Description

Technical field

The present invention relates to devices for dispensing viscous materials, such as creams.

State of the art

WO 2005/101969 describes a refillable bottle adapted to re-take and dispense a liquid, such as a perfume. A refillable bottle comprises a bottle having a lower portion and an upper portion, an opening provided in the upper portion, the opening being made covered, and a refill mechanism provided in the lower portion. The liquid is received by a refill mechanism from a standard bottle, preferably provided with a spray mechanism, and is dispensed through an opening.

The refillable bottle described in WO 2005/101969 is unsuitable for viscous materials such as pastes, creams and liquid soaps. For example, cream may accumulate in large amounts in areas within the dispenser that are not available for bottle dispensers.

Cream bottles available on the market are not reusable; furthermore, they are usually made of hard and thick plastic to withstand unacceptable mechanical stress, such as accidental falls, and thus pose a serious environmental damage.

One object of the invention is to provide a cream bottle that is refillable; another task is to perform such a bottle with the possibility of replenishing it in small quantities, which are essentially issued from the bottle; another task is to make this bottle so that the cream in the bottle can be substantially removed from the bottle using a dispensing mechanism.

SUMMARY OF THE INVENTION

In the claims, the word “comprise” and its variations, such as “comprises”, “comprising” and the like, indicate inclusion of the listed components, but in general do not exclude other components.

Detailed description

The present invention relates to the problem of contamination from the disposal of containers with viscous compositions, since containers are usually thrown away after one use. Additionally, due to the high viscosity of the compositions, a large amount of material remains adhered to the walls of the containers, etc. and thrown away with the container.

Adding a replenishment mechanism to containers allows you to reuse these containers, and miniaturization of replenished containers also allows you to do two important things: 1) put containers in a bag / bag / bag, etc. for convenient use outside the home due to the small size and 2) take small samples of the first viscous composition (for example, cream), and then take small samples of the second viscous composition, i.e. the user can simply change the composition. However, miniaturization also exacerbates the ejection of the material, since a relatively large amount of material remains inside the container, which can deteriorate, dry and crust, etc., and can adversely affect another composition that is introduced into the container. In this regard, it is important to include in the dispenser a mechanism that allows you to fully remove viscous compounds from the container.

Thus, in one aspect, a refillable viscous dispenser is provided that is designed to solve all these problems. In FIG. 1 dispenser 100 contains:

a bottle 111 having walls forming an upper cavity 114 and a lower cavity 116;

a viscous composition replenishment mechanism 106 configured to allow the viscous composition to enter the indicated upper cavity 114 when said replenishment mechanism 106 is fluidly coupled to a viscous composition source;

a viscous composition dispensing mechanism 102 configured to allow the viscous composition 7 to protrude from said upper cavity 114 to the outside of the bottle 111 when the dispensing mechanism 102 is actuated;

a gasket 105 configured to substantially seal said upper cavity 114 from said lower cavity 116, said gasket 105 being able to move towards the upper cavity 114 when the dispensing mechanism 102 is actuated and move towards the lower cavity 116 when the viscous composition enters 7 into said upper cavity 114.

When the dispensing mechanism 102 is driven, a certain viscous material 7, such as a cream, is removed from the outward mechanism 102 of the bottle 111. In some embodiments, the material removed from the mechanism 102 is replaced with secondary material pulled by the dispensing mechanism 102 from the same drive. When material 7 moves from the upper cavity 114, the pad 105 may rise, thereby maintaining pressure in the upper cavity 114 and keeping the (smaller) cavity 114 completely filled with cream. Air can simultaneously enter through the opening 171 into the lower cavity 116, thereby preventing pressurization below atmospheric in the lower cavity 116. When the replenishment mechanism 106 is activated, material 7 enters the upper cavity 114 and lowers the gasket 105, i.e. the upper cavity 114 expands and the lower cavity 116 narrows, releasing air through the opening 171.

Other embodiments have alternative means of maintaining vacuum / pressure.

In certain embodiments, the openings 171 in the walls may be completely absent so that only the openings in the bottle 111 are used by the replenishment mechanism and the dispensing mechanism.

The dispensing mechanism 102 may include a pump: when the pump is driven, for example, in some embodiments, it pushes downward, thereby compressing the space inside the pump containing viscous material, the pump pushes the viscous material. When the pump is not active, viscous material moves upward from the upper cavity 114 into the pump. In preferred embodiments, the pump is configured to prevent air from entering the upper cavity. In other embodiments, air has access to the upper cavity, but is pumped out using a pump.

Dispenser 100 may be a foam dispenser. In embodiments having foam dispensers, the dispenser may comprise two or more pumps that, when used, move both air and a viscous composition through a small opening to create foaming, for example, shaving cream. In preferred embodiments, air is preferably introduced into the pump (s) outside the bottle 111.

In some embodiments, the dispenser is automatic and is driven by a signal, such as a time activation signal.

As shown in FIG. 2, the dispenser 100 further comprises a lid 103 for closing the dispenser 102 and an outer bottle body 112 that complements the lid 103. The outer casing 112 has a transparent window 121 through which the level of material 7 can be measured to evaluate when to replenish the dispenser 100. However, , in certain embodiments, these features are absent, as shown in FIG. 3. Dispenser 200 likewise comprises a bottle 211, dispensing mechanism 202, replenishment mechanism 206 and gasket 205. The dispenser, as shown, is empty.

FIG. 3 is another embodiment 200, empty, that includes a bottle 211, dispensing mechanism 102, gasket 205, and filling mechanism 206.

FIG. 4 shows a bottle 211 partially filled, and FIG. 5 shows the same bottle 211 completely filled with a viscous composition 7.

The replenishment mechanism in FIG. 1 is defined as including a tube 104. Thus, the replenishment mechanism continues outside the bottle 111 and throughout the lower cavity 116 and the gasket 105 so that the composition 7 can be conditionally provided from the bottom of the bottle 111. The gasket 105 is sealed on the tube and in a bottle. In some embodiments, the tube may be proximal or flush with or even be part of the wall, in which case the gasket cannot be perforated, however, it can effectively seal the upper cavity from the lower cavity. FIG. 6 shows an embodiment 300 in which the replenishment mechanism 306 does not continue throughout the lower cavity 316. Instead, the replenishment mechanism 306 is installed in the dispenser 300 so that it directly extends to or in the upper cavity 314. The dispenser 300 may be particularly suitable for filling dispenser 300 of containers having dispensing heads with openings facing downward.

FIG. 7 and 8 illustrate the filling of a refillable dispenser 200 with non-refillable dispensers 400, 400 '. The dispenser mechanism 409 40 of the dispenser 400 shown in FIG. 7 is driven by a pumping action, while the dispenser mechanism 409 ′ of the dispenser 400 ′ shown in FIG. 8 is driven by indentation of the refillable dispenser 200 and the non-refillable dispenser 400 ′ towards each other. A bottle 411 containing a viscous composition can be compressed. In some embodiments, the replenishment mechanism comprises a check valve. In some embodiments, the dispensing mechanism comprises a shutoff valve (to help prevent air from entering the upper cavity 114 through the valve). In some embodiments, both the replenishment mechanism and the dispensing mechanism comprise a check valve.

Commercially available dispensers may possibly be replenished by removing their dispensing mechanism, but for all practical purposes, such replenishment is time consuming and complex, and thus they are essentially non-replenished. Moreover, their size, usually 250 ml or more, is substantially larger than refillable dispensers, which usually have a size of less than 100 ml, so there are few reasons to replenish large dispensers.

Thus, according to another aspect, a kit is provided comprising any refillable dispenser of the types described above and at least one adapter, each adapter being configured to provide a sealable connection and a fluid connection of the non-refillable viscous dispenser with a filling mechanism for a refillable dispenser. Each adapter is suitable for the special design of the dispenser dispensing mechanism. Thus, a set of adapters can be used to connect the first refillable dispenser with various commercially available non-refillable dispensers.

Many commercially available dispensers have a dispensing head (not shown) that can be removed to allow access to the dispensing mechanism 409 of the non-refillable dispenser 400, then the available mechanism 409 can simply be connected to the replenishment mechanism. Such removal will usually open access to such a structure as the stem 415 of the dispensing mechanism 409 (see FIG. 7).

The adapter may be a tube having ends with the same or different sizes. Typically, one end is firmly mounted to the replenishment mechanism of the refill dispenser, and the other end is firmly mounted to the stem of the dispenser mechanism of the refill dispenser to create a sealed connection for transferring the viscous composition from the refill dispenser to the refill. Alternatively, the adapter may be the dispensing mechanism itself, which replaces the original dispensing mechanism of the non-refillable dispenser.

In other embodiments, the non-refillable dispenser is simply a receiver without any dispensing mechanism at all, for example, a cream jar with a thread on top and a lid with a corresponding thread, and then the adapter is connected to the jar without a lid. In preferred embodiments, the refill mechanism of the refillable bottle further comprises at least one sealing ring, as shown in FIG. 1, a ring 161 in the replenishment hole 160 below the shutoff valve (in FIG. 1 comprising a ball 162 and a compression spring 163) to provide a sealed connection.

According to another aspect, a kit is provided comprising a refillable dispenser and a non-refillable dispenser. The uniqueness of the non-refillable dispenser in this embodiment is that the refillable dispenser and the non-refillable dispenser are configured to provide a sealable connection to the non-refillable dispenser with a refill mechanism, preferably without the need for an adapter. Such a non-refillable dispenser may be a commercially available dispenser, wherein the rechargeable dispenser is specially adapted to the size of the recharge mechanism of the dispenser of the non-refillable dispenser, but perhaps more often the non-refillable dispenser is also specially adapted to easily and closely match the rechargeable dispenser.

Typically, a non-refillable dispenser will be economical and too large to carry in a bag, pocket, etc. A non-refillable dispenser further minimizes material waste.

It should be noted that unlike a non-refillable refillable dispenser is ideal for use at home, a refillable dispenser is ideal for use on airplanes, since currently only very small containers of viscous compounds are allowed to fly on board an airplane.

Certain embodiments may be modified to have a lower atmospheric pressure in the upper cavity, at least when the upper cavity is substantially empty of material and ready to receive secondary material. This can be done by having a gasket that cannot move all the way to the upper part of the upper cavity, so that after delivery is complete, a space can be left in which pressure can be created below atmospheric. For example, see FIG. 9-12.

Dispenser 500 comprises a rigid body 501, in which there is an upper cavity 502 sealed from the lower cavity 516 by a gasket 530. In particular, the housing 501 has sufficient rigidity so that the volume of the upper cavity 502 remains substantially constant. The upper cavity 502 may, for example, have a capacity between 1 and 20 ml (whereby the dispenser has traditional pocket sizes).

The housing 501 may be integral, for example, made by injection molding or blown extrusion, or may consist of several parts cast and further assembled, for example, by ultrasonic welding, they may be made of rigid plastic material, metal, for example aluminum or glass .

The dispenser 500 also comprises a dispenser 503, which is sealed to the housing 501, in particular in the upper opening of the housing. In the illustrated embodiments, the dispenser comprises a dispensing pump 503, manually actuated by a push button 504.

Pump 503 comprises a housing 505 equipped with means for supplying material. In the figures, the supply means comprise a plunger tube 506 located in the upper cavity 502, said tube being equipped with a valve 507 for admitting the product (viscous material) into the pump 503. A push button 504 is mounted on the nozzle 508 of the pump 503, which comprises a piston 509 mounted near said nozzles in order to limit the metering chamber 510 in the housing 501. The piston 509 provides nozzle openings 511 for the nozzle 508 to open or close during delivery or, accordingly, the suction movement of said nozzle.

The push button 504 comprises an upper region allowing the user to apply pressure with the finger to said push button in order to be able to move it axially within its movement to actuate the pump 503, the push button 504 being returned within its suction movement traditionally carried out by a spring 512 In the shown embodiment, the inner region of the housing 505 of the pump 503 is equipped with an extension 513 with which the lower end of the spring 512 is docked.

The push button 504 is equipped with a head 514, which is configured to distribute the product radially. However, the invention is not limited in a particular way to product delivery.

The dispensing method provides, prior to the initial filling of the upper cavity 502 with the product, the inclusion of the indicated empty reservoir for the product in connection with the air intake device and actuating the specified device in order to create negative pressure inside the specified reservoir.

According to one embodiment, the air suction device comprises a vacuum bell in which a dispensing mechanism 505 is located, wherein a sealed installation of the extraction device 503 on the housing 501 is achieved after the actuation of said bell. Thus, a negative pressure is generated in the upper cavity 502, and then the extraction device 503 is sealed so as to maintain the indicated negative pressure.

According to another embodiment, an air suction device, for example, a vacuum pump, is connected to the extraction device 503 after it is sealed on the housing 501, while air is sucked from the upper cavity 502 through said extraction device. In an embodiment, air can be sucked in by means of a replenishment mechanism (not shown) by enabling it to be connected to the air suction device after a sealed installation of the extraction device 503 on the housing 501.

The dispensing method provides for the initial implementation of the initial filling of the upper cavity 502 by including the product source in a tight connection with the specified upper cavity 502 by means of a replenishment mechanism so that negative pressure causes the filling of the specified reservoir by suction of the product contained in the specified source. Subsequently, the consumer may operate the extraction device 503 in order to deliver the finished product.

One click on the replenishment mechanism can cause the valve to open in the replenishment mechanism, as well as possibly opening the refillable dispenser pump so as to form a product transfer path between the source and the upper cavity 502. Further, negative pressure compensation provides filling. Subsequently, when the upper cavity 502 is filled, the negative suction pressure becomes zero, and then the replenishment mechanism valve closes, and in the next step, the product contained in the upper cavity 502 can be discharged by the extraction device 503.

In this regard, the dispenser 500, which is supplied to distributors, may be an empty product and may have a negative air pressure, and the specified negative pressure makes it possible to perform further initial filling, in particular during the transfer of the dispenser 500 to the consumer according to the product that they wanted to purchase and / or experience. In this regard, the method allows for a very diverse initial filling, which in particular allows distributors the simplified use of the dispenser 500s, in particular as a dispenser 500s for testing samples.

The versatility of the dispensing method can also be improved by linking the tags on the housing 501 during the initial filling of the upper cavity 502 with the product, in particular according to the specified product. The label may have a detachable part containing a special commercial offer for the distributor in order to encourage the consumer to return and purchase the selected product.

Regarding FIG. 9 and 10, the extraction device in embodiments 500, 600 refers to the airless type without involving air in the upper cavity as a compensation for the volume of the dispensed product. To do this, the housing 505 of the pump 503 in the embodiment 500 does not have a vent.

However, since pumps with a vent are most applicable, it may be preferable to create negative pressure in the upper cavity even with this type of pump. To do this, as shown in embodiment 600 of FIG. 10, the housing 605 is provided with a vent 626, which overlaps with the possibility of sealing by installing it in the rigid housing 601 (FIG. 10A). In particular, the seal between the housing 605 and the rigid housing 601 is further performed at least under the ventilation hole 626 so as to prevent the passage of air from the pump 603 in the upper cavity 602 through the hole.

In FIG. 10, a seal is also achieved above the vent 626, which does not impair operation without air and is a bit easier to achieve.

A sample of the product without involving air in the upper cavity 602 makes it possible to create a negative pressure in said upper cavity 602, which increases with delivery. In particular, in order to ensure complete emptying of the upper cavity 602, the maximum air height above the product during initial filling must be such that the negative pressure reached at the end of the emptying is at a maximum equal to the negative pressure reached by the pump 603.

In this embodiment, the dispensing method further enables the next filling of the upper cavity 602 by densely engaging the product source (non-refillable dispenser) with said upper cavity 602 by means of a replenishment mechanism such that negative pressure causes the filling of said upper cavity 602 by suction of the product contained in specified source.

Regarding FIG. 11 and 12, the product is removed to remove air in the upper cavity so as to prevent the next filling of the specified upper cavity by suction. To do this, the pump contains a vent, which is configured to provide compensation for the volume of product recovered in the upper cavity with air.

Regarding FIG. 11, the pump 703 in the embodiment 700 is installed in the housing 701 by a sleeve 727, in which the housing 705 is sealed. A ventilation hole 726 is formed in the housing 702 radially opposite to the larger diameter 727a, which is formed on the sleeve 727 so as to leave the specified hole free in order to allow air to enter the upper cavity 702 (FIG. 11a).

According to one embodiment, the dispensing method may, prior to initially filling the upper cavity with the product, ensure that the extraction device is mounted on the housing in a storage position in which the airtightness of the upper cavity is enhanced, while said extraction device is subsequently moved to the dispensing position. This is because in the dispensing position, the constant airtightness of the upper cavity having a negative pressure may not be sufficient, in particular in the presence of a ventilation opening, to ensure that this negative pressure is maintained for long periods of storage.

In addition, nevertheless, in order to improve the maintenance of negative pressure over time, the replenishment mechanism can be covered with the possibility of removing a sealing cap (not shown). The lid can be welded in a recess formed at the free end of the lining (not shown) so that the lid completely covers the replenishment mechanism, and the lid has a free edge that allows it to be removed for the purpose of initial filling.

Regarding FIG. 11 and 12, the pump 703 is mounted so as to be able to slide in relation to the housing between the upper storage position in which the ventilation hole is blocked (FIG. 12) and the lower delivery position (FIG. 11), in which said ventilation hole 726 is free for ensure air filling.

In particular, the housing 703 is installed in the sleeve 727 with a fit suitable for sliding, and the passage between these positions is achieved by pressing the push button 704 during the initial actuation of the pump 703. The sleeve 727 has a step 727b defining the upper diameter 727c for a sealed installation housing 705 in order to close the ventilation hole 726, and an enlarged lower diameter 727, leaving the specified ventilation hole free, while the specified pump housing has a stopper 729 to stop Sliding movements in sleeve 727.

The replenishment of the dispenser 700 may facilitate pressures below atmospheric. In embodiments in which the material is not too viscous, for example, various lotions are more suitable. Shaking the lotion (thereby sometimes decreasing the viscosity) immediately before replenishment can facilitate replenishment in such cases.

Certain creams and lotions and colloids may have a precipitate, lumps, etc., so that the separation of solid particles is also undesirable as the product used, and in some embodiments, may interfere with the operation of the dispenser, in which case it may be preferable to shake the dispenser immediately up to issuance. In such cases, excessive shaking of the lotion can be reckless, since shaking can excessively reduce the viscosity of the viscous material. A certain experiment may be necessary to obtain the most expected results, both in terms of the quality of the material and in relation to a more satisfactory operation of the dispenser. Certain embodiments may be more suitable for particular types of viscous materials.

Returning to FIG. 1, note that the upper portion of the pad 105 has a bullet shape, i.e. narrowed at the top, as it is part of the upper cavity 114, facilitating emptying of the bottle 111 from the viscous material 7. The upper part of the gasket 105 can generally correspond to the shape of the upper part of the upper cavity so that the gasket 105 can simply reach the uppermost part of the upper cavity 114 and essentially remove viscous material from bottle 111, if necessary. However, in other embodiments, the top of the bottle 111 is not bullet-shaped. Moreover, the gasket is preferably flexible and, therefore, in embodiments having bullet-shaped upper cavities, the gasket may be able to simply move and fit snugly against the walls on the upper part of the upper cavity.

The examples described above represent the various selected embodiments of the cream refillable dispenser. Note that additional embodiments are considered as also falling within the scope of protection of the present invention. The scope of protection of the present invention is determined by the claims and includes both the totality and the subset of the various features described above, as well as its changes and transformations that will be encountered by a person skilled in the art when studying the above description.
