Description

The present invention relates to a protective cap for a container, and further to containers provided with such a cap.

More specifically, the invention relates to a protective cap for a fluid container, in particular a compressed gas bottle, comprising a cap body and an interface ring for mounting the cap body on the container.

The protection of taps or pressure reducing valves on pressurized fluid containers against impacts and various attacks is generally provided by an accessory called a cap that can be "open or" closed (see NF E29-640). The general features and characteristics of these caps are described, for example, in NF EN 962.

The closed cap provides complete protection when the tap is in place, but needs to be removed in order to access the tap. Thus, the closed cap no longer protects the tap when the bottle is in use.

Open caps are relatively simple when designed to protect conventional taps. Generally more complex

EP2,016,329B1

16E06639.doc are faucet caps with integrated pressure reducers because their release gives access to control and visibility of pressure gauges (cf. eg FR 2 774 452 A1). The design of the cap must take into account several restrictive conditions, which are sometimes contradictory. In order to perform its protective function while allowing access to the tap and also to ensure ergonomic use (when transporting the bottle as well as when filling or bottling liquid), the cap must be as close as possible. Furthermore, in order to allow inspection and maintenance of the tap, it must be very open and / or removable. The removable cap is useful for the maintenance of the faucet, but also for the maintenance of the cap itself (dyeing, cleaning, repair or replacement). However, the fitting and removal of the cap must be relatively simple and its mounting must be sufficiently reliable to prevent the cap from being released or lost during handling or transport. To allow access to control and visibility of pressure gauges or other components, the cap must be positioned accurately with respect to the faucet.

Finally, the cap must conform to the type of attachment available on the bottle on which it will be placed (such as the "neck type" attachment according to NF EN 962). However, there are different types of attachments for protective caps: plain neck, threaded neck with different diameters (especially 78 mm and 80 mm). Typically, the necks have a larger outer diameter than the spatial envelope of most conventional faucets. This allows the cap to be mounted on a faucet that is already mounted on the container. However, a large number of taps, and in particular taps with integrated pressure reducing valves, have a spatial envelope larger than the outer diameter of the necks.

EP 2,016,329 B1

Accordingly, it is necessary to either provide a removable cap that can be mounted on the container without having to remove the tap, or mount the faucet up to the cap. In the latter case, this makes it impossible to remove the cap without first removing the tap. Installing the tap is a delicate operation, especially since the tightening torque with respect to the bottle must be respected. Disassembly of the faucet can in turn result in damage to the faucet, for example due to wear of the tapered thread of the neck or to the marking of the surfaces in contact with the tightening and loosening tool.

US 4,880,134 discloses a smooth protective cap that is attached to a container by a threaded adapter ring. However, this solution is not suitable for taps whose space shell does not enter the diameter of the adapter ring. US 4,352,370 discloses a container comprising a faucet and a protective cap.

According to other known solutions, the protective cap may be formed of two parts that grip the smooth neck. However, this solution is not suitable for threaded necks and is only adapted to a single neck profile (diameter and height).

It is an object of the invention to overcome all or at least some of the above-mentioned disadvantages of the prior art.

For this purpose, the container according to the invention is formed according to claim 1. Individual embodiments of the invention may comprise one or more of the following features:

the ring has resilience which allows for temporary enlargement and / or constriction of the aperture during insertion and / or removal;

EP2,016,329B1

The end of the ring lying substantially over the center opposite the opening has an area that is weakened and / or deformed relative to the rest of the ring;

the ring has an inner surface intended to be mounted on the outer surface of the container and an outer surface intended to cooperate with the surface of the cover body to be mounted on the container, the inner surface of the ring being smooth or having fastening reliefs, such as thread;

the outer surface of the ring comprises a fastening or positioning profile designed to cooperate with a complementary surface profile of the cover body;

the outer surface of the ring comprises at least one cavity and / or relief;

the cover body comprises at least two parts which can be joined;

the cover body comprises at least two parts which can be joined to clamp the ring on the container;

the ring is sized to have clearance relative to the outer dimensions of the neck;

the ring forms an open ring;

the at least two portions of the cover body comprise flange and bolt fasteners;

the at least two portions of the cover body comprise openings for visibility and / or access to elements located within the cap;

said at least two portions of the cover body forming a cage, preferably metal;

the ring comprises metal and / or metal alloy and / or plastic type material.

In a preferred embodiment of the invention, the cover body can be attached to the neck by means of an interface comprising

EP2,016,329B1

16E06639.doc

a slit ring, the inner surface of which is provided with a thread which cooperates with the thread of the neck.

The outer profile of the ring has a rotating surface that cooperates with a complementary profile located in the inner surface of the cap or cover body.

The slit of the slit ring has a width determined so that the ring can be fitted when the tap or tap with integrated pressure reducer is already mounted on the bottle. The neck and the slit ring are preferably threaded. This allows the ring to be screwed onto the neck and placed at an ideal height for positioning the cap relative to the tap or tap with integrated pressure reducer.

To facilitate the fitting and removal of the cap, the cap may be divided into at least two parts which first join together without special tightening on the ring. This allows the cap to be positioned in the correct angular position with respect to the faucet. Then it is sufficient to tighten the connected parts of the cap or cover body, which simultaneously secures the cap on the slit ring and the slit ring on the bottle neck. Thus, the slit ring can be made with slight play relative to the neck, making it easier to manufacture and fit. This clearance can be compensated after tightening the cover body. In order to achieve greater grip between the slit ring and the neck, the inertity of the slit ring can be reduced locally, for example in a region lying over the center opposite the slit. To this end, it is possible to provide a notch and / or aperture here, which the person skilled in the art would design to achieve a compromise between its elastic efficiency and the ease of its formation.

EP 2,016,329B1

E06639.doc

The same cap can be mounted on the slit rings of different internal shapes or sizes, allowing it to be adapted to different types of bottles. Similarly, the same slit ring can receive different caps. This makes it possible to replace the cover body without having to replace the slit ring forming the mounting interface.

The cap may be used with smooth necks, requiring the use of a suitably cut slit ring. In this variant, the fineness and accuracy of the height positioning of the ring on the neck is somewhat worse than when the slit ring is threaded and screwed onto the threaded neck. However, the height deviations can be corrected either by using other slit rings, if these deviations are general, or by using interlinings cut as well as placed below the ring to form a dimension at the desired height.

Another solution may be to use slit rings whose outer profile is not centered with respect to thickness. That is, the protruding or recessed portion of the outer surface of the ring is closer to one of the flanks (upper or lower) of the ring than to the other flank (lower or upper) of the ring.

When mounting the ring with its protruding flank facing upwards, the cap will be mounted in a position that is relatively higher. Conversely, when the projecting flank is mounted downward, the cap will be mounted in a relatively lower position. To facilitate the selection of the slit ring and its orientation, a template carrying different notches can be easily formed. In another variant, the operator may be guided by automatic metrological means.

EP2,016,329B1

For smooth-necked bottles with circlips locking as described in US 3,776,412, the slip-ring lock against displacement can be provided with the same circlips as used. at the swivel cap. Tightening the cover body then fixes the angular position and disturbs the clearance between the cap and the bottle.

Other particularities and advantages of the invention will be apparent from a reading of the following description given with reference to the accompanying drawings, in which:

Fig. 1 is a perspective view of an upper portion of a pressurized gas bottle provided with a tap with an integrated pressure reducing valve without a protective cap; Figures 2 to 6 are perspective views showing a sequence of steps for mounting a protective cap according to one embodiment of the invention to the container of Figure 1;

Fig. 7 is an enlarged perspective view of the container of Fig. 1 fitted with a protective cap fitted in accordance with one embodiment of the invention.

[0022] FIG. 1 shows a compressed gas bottle 1 provided with a tap 2 with an integrated pressure reducing valve, which comprises, as is known, control means and pressure gauges.

Referring now to Figures 2 to 7, a sequence of steps for assembling one embodiment of a protective cap according to the invention will be described.

EP2,016,329B1

As seen in Fig. 2, the slit ring 3 is in a position allowing it to be positioned by sliding it around the neck 4 of the bottle 1 (arrow T). More specifically, the ring 3 can be fitted or threaded around the tap and / or at the top of the neck 4 of the bottle 1 by moving the ring 3 in a direction substantially perpendicular to the vertical axis of the bottle 1. This means that the ring 3 can be placed around the base 2 or in the region of the top of the neck in a direction that extends substantially transverse to the axis of the bottle 1.

The inner surface 23 of the ring 3 is provided with a thread which cooperates with a composite thread formed on the neck

4. The outer surface 33 of the ring 3 comprises a peripheral rib intended to cooperate with a mating groove formed on the inner surface of the cover body to be mounted on the ring 3 (cf. below).

The width of the slot 13 in the ring 3 is determined so that the faucet can pass through the slot 13 inside the ring 3. When the slit ring 3 is placed on the neck 4 of the bottle 1, the axes of the bottle 1 and the ring 3 substantially coincide. In this position, the ring 3 can be screwed onto the neck 4 by rotation (arrow R in Fig. 3).

The dimensions of the ring 3 can be determined with sufficient clearance to make screwing of the ring 3 easy. Indeed, at the end of the cap assembly, the ring 3, which has a certain flexibility due to its slot 13, will be clamped on the neck 4 and the clearance will be leveled.

[0028] FIG. 4 and 5 show the location of the two half caps 5,

6, which will be clamped on the slit ring 3 by two screws

7. Half caps 5, 6 for this purpose in their lower part

E06639.doc comprises a half flange 8, complementary to the outer surface of the exemplary embodiment). Screws with 7 tapped holes

Of course, the attachment of two half-caps 5, for example cotters, elastic as in the case of a bicycle wheel, may be provided to <

the inner surface of which is 33 in the form of a ring 3 (the groove in this is intended to cooperate through the flanges 8 of the half caps 5, any other means 6 forming the cover body, such as clamps, cam mounts like scaffolding clips, clips, loop lugs, rivets The choice of a particular fastening system will depend, in particular, on the intended ease or difficulty of dismantling, the fastening being capable of fulfilling the integrity function of the seal.

In this way, after clamping the half caps 5, 6 around the ring 3 mounted on the neck 4, the assembled cap is connected to the ring 3 which is secured to the neck 4.

[0030] FIG. 6 shows possible complementary parts for the cap composition: a manipulation knob 9 comprising in its lower part a threaded length 19, a washer 10 and a flange 11 having a threaded crown in its center. Thus, the length 19 of the threaded knob 9 can be screwed into the crown flange 11 after placing the flange 11 under the part (bars forming the lattice) forming the upper part of the half caps 5, 6.

[0031]

In another variation, the knob may rotate freely to facilitate transport of the bottle.

As can be seen in Fig. 7, the crown flange 11 connects, in cooperation with the washer 10 and the knob 9, the upper parts of the two half caps 5, 6. This gives the entire cap a good stiffness. Clamping knob 9 screwed in crown flange

Of course, the mechanical connection between the upper parts of the two half caps 5, 6 is not limited to the example described above. Thus, the upper portions of the two half caps 5, 6 may be secured by any equivalent means, for example complementary fastening systems arranged on the half caps 5, 6.

Similarly, the construction of the cap is not limited to the embodiment described above, in which it is formed by a metal cage with optional reinforcements 15, 16 (Fig. 4). The cap body forming the cap may have any shape and any protective structure and may include any other material or combination of materials, in particular plastic.

For example, the cover body may comprise a single surrounding partially open portion that will cooperate with the attachment flange. This means that, compared to the embodiment of Figures 2 to 7, one of the half caps will have a more surrounding shape, whereas the other half-cap will only be replaced by an assembly (eg, half-flange) that will not participate in the faucet protection or very little.

Thus, it can easily be assumed that the invention, although proposing a simple and inexpensive design, has a number of advantages over known solutions. Thus, the cap according to the invention allows simultaneously:
