Definitions

  • This invention pertains to self-closing caps for squeeze-type containers from which the contents is extruded by the application of pressure on the body of the container and in which a pair of coaxially disposed seals open to discharge the contents when pressure is applied and which automatically close when squeeze pressure is removed from the container.
  • closure caps have been employed for collapsible containers utilized for storing extrudible pasty materials such as for example toothpaste, ointments, beauty creams, food product spreads and the like.
  • Such containers usually comprise an extrusion nozzle, having been provided with a screw-on closure cap of solid composition whereby said cap has had to be removed every time it was desired to discharge the contents from the container.
  • this circumstance frequently led to the loss of the closure cap so that in many cases, the container with its contents had to be discarded, or at least, there existed the danger of an undesired extruded portion of the contents taking place by inadvertant compression of the unclosed or urcapped container.
  • the prior art devices do not ade ⁇ quately cut or sever the extruded portion of the contents from the unextruded portion remaining in the tube so that contamination and wastage of contents is encountered. Therefore, a long standing need has existed to provide a novel closure means for a collapsible container which is an integral part of the container and which will readily dispense the contents thereof in an extruded manner without encountering the above enumerated problems.
  • the automatic closure nozzle disclosed herein comprises a self sealing nozzle carried on a collapsible or squeezed-type container composed of a mouldable material so that when deformed, the deforming pressure forces the contents to extrude from the nozzle in a continuous stream as long as pressure is applied. Upon the release of pressure, the nozzle is closed and extrus- ion ceases.
  • the nozzle includes a flexible cap portion terminating at one end so as to define a discharge open ⁇ ing which is sealed by an inner and an outer seal, both of which include a plurality of stiff, triangularly shaped sections coaxially disposed in spaced apart relationship.
  • An accordion spring is operably disposed between the container at one of its ends and to the flexible cap portion at its other end midway between the inner and outer seals. Squeeze pressure on the collaps ⁇ ible tube causes the accordion spring to expand which actuates the seals from their closed position to an open position for releasing the contents of the tube through the discharge orifice. Upon release of the pressure, the contraction of the accordion spring causes the inner and outer seals to return to their closed and sealing position.
  • the present invention avoid the above enumerated problems and difficulties in that the closure means is self sealing after discharge of a desired amount of contents and the closure means as well as its attendant resilient actuator is integrally formed with and carried on the container so that the need for a separate closure means is obviated.
  • Another object of the present invention is to provide a novel closure means for a deformable or mould- able container which will effectively extrude the contents therefrom through an integral nozzle which includes closure means for nipping off the extruded portion of the contents and sealing the remainder of the contents from the discharge orifice.
  • Yet another object of the present invention is to provide a novel closure means for a squeeze type con ⁇ tainer which is integral with the container and which is reliable, easily maintained and which is not a separate unit requiring it to be removed before dis ⁇ charge of the contents.
  • FIGURE 1 is a front persepctive view of a typical squeeze type or collapsible container incorporating the novel integral automatic closure nozzle of the present invention
  • FIGURE 2a is a longitudinal cross sectional view of the novel closure nozzle and container shown in

  • FIGURE 4a is a view similar to the view shown in FIGURE 3a illustrating further pressure being applied so that the contents expands the resilient means to fully open the outer seal and partially open the inner seal of the closure nozzle;

  • FIGURE 5a is a view similar to the view of FIGURE 4a illustrating the outer and inner seals fully open;
  • FIGURE 5b is a view similar to the view of FIGURE 4b illustrating the outer and inner sealing means fully opened in accordance with the view of FIGURE 5a when full pressure has been applied to the container;
  • FIGURE 6 is a front elevational view of another embodiment of the present invention illustrating a single sealing means associated with the closure nozzle incorporating the present invention.
  • the novel automatic closure nozzle of the present invention is shown in the general direction of arrow 10 which is illustrated attached to a collapsible container 11 holding a quantity of paste ⁇ like material such as toothpaste, ointments or the like.
  • the closure nozzle 10 includes a flexible cap portion 12 which is suitably mounted or carried on the end of tube 11 by any suitable means and further includes an outer seal identified in general by the numeral 13.
  • the tube 11 includes contents as previously described illustrated by numeral 14.
  • the cap portion 12 not only includes the outer seal 13 but an inner seal 15 as well.
  • the nozzle 10 is of a self sealing nature for the squeeze-type container 11 and the cap portion 12 includes a cylindrical sidewall having one end carried on the end of tube 11 while its opposite end is reversed cr folded inward upon itself about a hinge area 16 of reduced thickness so that its extreme edge 17 is coaxially dis ⁇ posed with respect to the cylinder wall.
  • a discharge wall portion extending between the hinge or reduced area 16 and the edge 17 is identified by numeral 18 and this wall mounts the inner and outer seals 15 and 13 respectively.
  • the outer seal 13 comprises
  • a plurality of stiff, triangularly shaped sections such are suitably attached to the wall 18 and the inner and outer seals are arranged in fixed spaced apart relation ⁇ ship so as to form a double seal in cooperation with each other.
  • each section in the respective inner and outer seals overlaps to form a sealed closure in a first position and fully open in a second position to permit discharge of container contents through the discharge opening defined by the circular edge 17 of the wall 18.
  • the wall 18 is also attached to the tube 11 by means of an accordion type spring 21 which is normally biased in compression to pull the wall 18 downwardly in the direction of tube 11 so that the sections of the seals are tightly engaged in closure to prevent escape or leaskage of the tube contents 14.
  • the accordion spring 21 is urged into expansion so as to open the inner and outer seals to permit discharge of the contents 14.
  • FIGURE 3a Initial pressure placed on the tube 11 illustrates expansion of the spring 21 in FIGURE 3a so that the sections of the outer seal 13 spread apart as the flex ⁇ ible wall of the cap portion 12 expands and the wall 18 pivots about the hinge or reduced portion 16.
  • FIGURE 3b the sections 20 of the outer seal 13 are illustrated partially expanded to an open condition.
  • FIGURE 4a the pressure on the tube 11 has increased to the point where the accordion spring 21 is almost fully expanded and the outer seal 13 is almost in its fully open position and that the inner seal 15 is now partially open.
  • FIGURE 4b it can be seen that the seals are coaxially disposed with respect to each other and that once the outer seal is substan- tially open, the inner seal 15 begins to open.
  • FIGURE 5a shows the outer seal * 13 and the inner seal 15 is fully open so that the contents 14 may be extruded through the discharge orifice represented by the edge 17.
  • the accordion spring has been fully expanded against its normal bias because of the overpowering force or pressure of the contents as the tube is squeezed.
  • FIGURE 5b shows the open condition of both seals so that the product or contents may be dispensed therefrom.
  • FIGURE 6 another embodiment of the present invention is illustrated which includes a cap 30 having a discharge orifice illustrated in the general direction of arrow 31 which is sealed by a closure means 32.
  • the closure means 32 is identical to the outer seal 13 associated with embodiment 10.
  • the closure or sealing means 32 includes a plural ⁇ ity of triangular sections such as section 33 which are hingably carried at the discharge orifice 31 of the cap 30 so that when pressure is applied to the underside of the sections, the sections will expand or move to the position shown in broken lines so that the contents may be discharged or extruded from the cap 30 via the orifice 31.
  • the novel closure nozzle for collapsible containers is easy to use and will readily dispense or extrude a product contained in the tube or container 11. Opening of the closure or seals 13 and 15 is achieved by squeeze pressure on the tube or container 11 so that the contents 14 will cause the expansion of spring 12 against its normal bias and force the opening of the sections associated with the seals.
  • the flexible cap portion 12 will expand accordingly to accommodate opening of the seals. Therefore, expansion of the spring under squeeze pressure actuates the seals or closures to their open position and release of the pressure contracts the spring via its self bias to return the seals to their closed position.
  • the edges of the sections associated with each of the seals will nip or cut a portion of the extruded product so that a clean cut of the material being dispensed is made. In this manner, no overage or residue is encountered.
  • the sections 33 expand under squeeze pressure and upon the release of the pressure, the sections 33 will reverse to their closed position under their normal bias to the position shown in solid lines. The extruded product will be cut or severed accordingly and no overage or undesired material will be left outside the closure.

Abstract

Buse de fermeture automatique pour conteneurs souples qui s'ouvre pour laisser passer le contenu lorsque le conteneur est presse et qui se ferme lorsque la pression exercee sur le conteneur cesse. Le concept inventif est particulierement utile pour les conteneurs de pate dentifrice, de produits cosmetiques, de produits alimentaires et d'une variete de produits liquides et semi-liquides. Le concept inventif se rapport a une buse (10) a auto-fermeture pour un conteneur a presser (11) constitue d'un materiau pliable, qui comprend une partie flexible de couvercle (12) a une extremite afin de definir un orifice de decharge (17). Sur la partie formant couvercle, sont articules un obturateur interne (15) et un obturateur externe (13), chacun de ces obturateurs presentant une pluralite de sections (20) rigides triangulaires et disposees coaxialement ecartees les unes des autres. Chaque section dans les obturateurs interne et externe recouvre la section correspondante pour former une fermeture etanche dans une premiere position et ouvrir completement l'orifice dans une seconde position pour permettre d'exprimer le contenu (14) du conteneur a travers l'ouverture (17). Un ressort en accordeon (21) est dispose dans la partie formant couvercle (12) a mi-chemin entre les obturateurs interne et externe, et l'expansion du ressort sous la pression exercee sur le conteneur agit sur les obturateurs pour les amener dans leur seconde position, et le relachement de la pression contracte le ressort et fait revenir les obturateurs dans leur premiere position.
