Definitions

  • This invention relates to improvements to snap action closures.
  • Snap-action closures are used extensively on containers for liquids and creams, such as cosmetics and household cleaning products. While not necessarily more effective than other closures, such as screw closures for example, they are well liked by consumers and consequently have had considerable commercial success.
  • Figures 1a-1c show an example of a snap-action closure which is described in more detail in UK patent application GB 2 269 811.
  • Part of the wall at the dispensing end of the container is flexible and is defined by a thin section which acts as a hinge.
  • the hinge also defines an aperture through which a flexible panel must pass.
  • the area of the aperture is slightly smaller than the area of the flexible panel.
  • the flexible panel can either be in a convex, open position (not shown) or a concave, closed position (shown). By pressing on the flexible panel when it is in the convex and open position, it is deformed to pass through the smaller aperture, so as to reverse its curvature and snap into a concave opening in the container thus closing it.
  • a resealable closure comprises a curved flexible panel forming part of the wall of a container or cap therefore, the area of the curved flexible panel being greater than the area of the wall of the container or cap defined by a hinge line of action, so that the curved flexible panel may be forced to pass from a convex form to a concave form and vice versa with an over centre snap action as the curved flexible panel is caused to pass through area of the wall of the container or cap defined by the hinge, and the curved flexible panel being inwardly concave to at least partially close an opening in the container or cap when in a first position, and being outwardly convex to form a dispensing opening in the second position, wherein the container or cap has a seal comprising an elastic seal attached thereto which seals the opening when the curved flexible panel is in the first position.
  • the problem of leakage in the conventional snap-action closures described above is overcome by providing a resilient seal between the opening and the flexible panel which deforms when the flexible panel is closed to create a liquid-tight seal.
  • the gap in the region of the closure hinge is closed by the elastic flow of sealant material where very little, if any, closing force is otherwise exerted.
  • the seal may be co-injection moulded onto a portion of the perimeter of the opening or instead, or in addition, onto a perimeter portion of the flexible panel.
  • the seal may be an initially separate component which is then assembled to the closure during manufacturing.
  • the material of the elastic seal has an elongation of at least 100%, preferably at least 200%, most preferably at least 1000%, a compression set at 70°C of less than 30%, preferably less than 20%, most preferably less than 10%, a cone penetration (ASTM D217 for greases) of from 10 to 40 mm, an initial softening point of greater than 100°C and a stress relaxation of greater than 500 seconds.
  • the elastic seal can be a closed cell foam, silicone or polyurethane rubber, preferably it is an elastic gel composition.
  • the elastic gel composition exhibits a low compression set since this enables the seal to return rapidly to essentially the same form when the compressive force of the flexible panel is removed. It is desirable that the elastic gel composition is tacky, so that it conforms and lightly adheres to the mating surface. This enables the closure to survive transient pressure increases.
  • the seal is capable of adhesive release from the mating surface without rupture, and further should be sufficiently soft to accommodate some foreign material contaminating the seal surface without loss of sealing.
  • One particularly suitable material for use as a sealant is a liquid-extended polymer composition.
  • the polymer of the liquid-extended polymer composition is a block co-polymer. More preferably, the polymer of the liquid-extended polymer composition is a block copolymer having hard blocks and soft blocks. More preferably, the polymer of the liquid-extended polymer composition is a styrene-diene block copolymer.
  • the polymer of the liquid-extended polymer composition is a poly(styrene-butadiene-styrene) block copolymer (SBS), a poly(styrene-isoprene-styrene) block copolymer (SIS), a poly(styrene-ethylene-butylene-styrene) block copolymer (SEBS), a poly(styrene-ethylene-propylene-styrene) block copolymer (SEPS) or a poly(styrene-ethylene-propylene) block copolymer (SEP).
  • SBS poly(styrene-butadiene-styrene) block copolymer
  • SIS poly(styrene-isoprene-styrene) block copolymer
  • SEBS poly(styrene-ethylene-butylene-styrene) block copolymer
  • SEPS poly(s
  • suitable elastic gels include bio-gels, ie gels derived from plants and animals. Examples of these include polysaccarides, for example hydroxypropyl cellulose, derived from cellulose; or protein gels such as gelatin, derived from collagen; and, latex rubber.
  • a package comprising the combination of the container and a resealable closure according to the present invention is capable of containing a liquid under pressure, and in particular a liquid which contains a dissolved gas. Accordingly, the invention may be used to store and dispense carbonated beverages.
  • the container comprises a flexible tube which may contain a paste or cream.
  • the container has a tab fitted to or integral with the flexible panel, to assist operation of the resealable closure.
  • Figure 1a is a cylindrical closure for attachment to a container, comprising a body 1, with a flexible panel 2 attached to the cylindrical wall, and an end wall 4 against which the flexible panel 2 closes - that is, the curved flexible panel 2 co-operates with a substantially matching cut-out 5 in the end wall 4.
  • One or more ribs 3 attached to or integral with flexible panel 2 stiffens the flexible panel 2 in the longitudinal direction, whilst maintaining flexibility in the radial plane; this results in a crisp and repeatable action of the closure.
  • Figure 1b is a scrap cross-section through the end wall 4 of closure shown in Figure 1a, showing how the flexible panel 2 closes against the cut-out 5 in the end wall 4.
  • FIG. 2a and 2b An example of the present invention is shown in Figures 2a and 2b.
  • the aperture 8 is sealed by the application of a seal 9 to the cut-out 5.
  • the seal 9 may not be desirable or possible for the seal 9 to join with the film hinge 7, particularly if the seal 9 is to be co-injection moulded onto the cut-out 5, where for certain sealant materials, the moulding temperature would melt the film hinge 7.
  • a small gap 10 may remain between the seal 9 and film hinge 7; this is not detrimental because the sealant material will flow to seal the small gap 10. If the application so requires the sealant material may be moulded onto the flexible panel 2.
  • the seal 9 is sufficiently soft to elastically flow into the apertures 8 and 10, thus to form a seal between the adjacent surfaces of the cut-out 5, flexible panel 2, and film hinge 7. Even though the closing force of the flexible panel 2 is virtually zero at the film hinge 7 area, the sealant material elastically flows into the apertures 8 and 10, and will in fact exert a small pressure against the adjacent surfaces, and compensate for the lack of closing force in this area.
  • a sealant material comprising a liquid-extended polymer composition is particularly effective in this application as it acts almost as a hydraulic fluid, so that the pressure exerted in the centre of the flexible panel 2 is transmitted laterally until the pressure throughout the seal 9 is nearly uniform.
  • Figures 3 and 4 show containers having a flexible panel closure, in the closed and open positions.
  • the flexible panel 2 is attached to the top wall 11 with a film hinge 7 and closes against the cut-out 5 in the side wall 12.
  • This arrangement is preferred for pourable liquids such as fruit juice or milk, because the air can enter the container via the open part marked Z, whilst the liquid pours from the lower part K, and this prevents "glugging" caused by air passing through the liquid and into the container.
  • a lip 13 extending from cut-out 5 helps the liquid to pour in a controlled fashion, and may also serve to provide a convenient opening from which to drink.
  • the lip may be the remainder of the tamper-evident device after removing the tear-off strips described below with reference to Figures 6a and 6b.
  • the flexible panel 2 is attached to the side wall 12 of a container by film hinge 7, and closes against a cut-out 5 in the end wall 4 of the container. This arrangement is suitable for more viscous liquids, powders and granules.
  • FIG. 5 shows a flexible tube type of container frequently used for creams and pastes.
  • Flexible tube 14 has a flexible panel closure 2 attached to end wall 4 with a film hinge 7, and which closes against the cut-out 15 in side wall 16.
  • a seal 9 as previously described is attached to the flexible panel 2 or the cut-out 15.
  • the side wall 16, cut-out 15, film hinge 7 and flexible panel 2 are moulded integrally with the flexible tube 14.
  • the flexible panel 2 may be thermo-seated or otherwise bonded to the cut-out 15 to provide tamper evidence, as described below.
  • the advantage of this design is that the flexible tube type of container may be filled from the open end, and heat sealed, crimped, or otherwise sealed to retain the contents, to provide a cost-effective pack.
  • Another advantage of this embodiment is that the tube may be safety stood upright on the closure end without the contents leaking.
  • Figures 6a and 6b are a scrap cross-section on the longitudinal axis through a flexible panel type of closure, and illustrate a principle applicable to all of the examples described herein.
  • Body 1 has an end wall 4, and flexible panel 2, shown in the open position.
  • the seal 9 is moulded onto either the sealing face of cut-out 5, or preferably onto the flexible panel 2, when the flexible panel 2 is in the open position.
  • the flexible panel 2 has a strip 17 attached by a thin web 18, and the cut-out 5 has a flange 19, also with a rib 17 attached by a thin web 18.
  • the flexible panel 2 is then closed as shown in Figure 6b, and the strips 17 are heat sealed together or otherwise sealingly bonded.
  • the thin webs should be adjacent to one another.
  • Seal 9 is compressed to seal the aperture, and a further seal is provided by the bonded strips 17.
  • the bonded strips 17 are torn off along the line of the thin web, which permits the flexible panel 2 to be opened.
  • the seal 9 then performs as previously described.
  • Figure 7 shows an enhancement which may be adapted to all of the foregoing flexible panel types of closure.
  • Cap 20 has a flexible panel 2, and attached to it by frangible means at approximately right angles is a tear-off strip 21, having a finger grip 22. This construction prevents the flexible panel 2 from flexing until the tear-off strip 21 is removed.
  • FIGs 8a-8f An alternative method of making a flexible panel closure is shown in Figures 8a-8f, where the flexible panel is an initially separate component.
  • body 1 has an end wall 4, and a panel 22 between the end wall 4 and body 1.
  • the panel 22 is perforated by an aperture 23, and the wall 24 of the body 1 is cut away to form a groove 25 around the panel 22.
  • the groove 25 extends to form a pocket 26 between the wall 24 and panel 12.
  • a hole 27 is formed through the wall 24 into the pocket 26.
  • Flexible panel 2 has a retaining clip 28 having a hole 29 through, and is attached to the flexible panel 2 by at least one frangible connection 30.
  • the hole 29 is of a size to engage with the frangible undercut projection 31 on the top surface of the end wall 4.
  • a detent 32 is sized to fit into the hole 27 in wall 24 of the body 1.
  • a seal 9 is attached to the perimeter of the flexible panel 2.
  • a view of the other side of the flexible panel 2 shows the seal 9.
  • the flexible panel 2 is inserted into the groove 25 until the detent 32 engages in the hole 27.
  • the undercut on detent 32 ensures that the panel 2 cannot be removed once assembled.
  • the hole 29 is then pushed over the frangible projection 31, and again, the undercut on the frangible projection prevents removal without breaking the projection.
  • Figures 8b and 8c are cross-sections to show the flexible panel in the open and closed positions. respectively, and how the seal 9 seals against the panel 22.
  • Figure 8d shows a rear view of the flexible panel 2.
  • Figure 8e shows the assembled closure
  • Figure 8f shows the appearance after removing the retaining clip 28 from the flexible panel 2. This breaks the frangible projection to leave a small pip 31a, thus providing evidence that the closure has been opened.
  • the shape of the seal 9 should follow the shape of the aperture 13, so that product does not accumulate in the pocket 26. Again, it is quite possible to mould or otherwise attach the seal 9 to the face of panel 12, surrounding the aperture 13.
  • Figures 9a-9d and Figures 10a and 10b show a closure of the flexible panel type, where the sealing element for the moveable panel is continuous with a seal for sealing between the closure body and its associated container.
  • Figure 9a shows a cap 20 comprising a side wall 1 and end wall 4, and the flexible panel 2 attached by the film hinge 7 to the end wall 4.
  • the flexible panel 2 is shown in the open position for clarity.
  • Figure 9b is a view of the inside of the cap 20.
  • a seal 9 is moulded into or otherwise attached into a groove 33 on the inside face of the end wall 4, and continues over the inside face of the flexible panel 2.
  • the seal 9 may be likened to an 'O' ring (or similar section seal), fixed to the end wall 4 of the cap 20, and free to move with the flexible panel 2.
  • 35 is a container or the body of a cap (for example a screw cap) having a rim 36 and cut-out 37, the shape of which conforms to seal against the seal 9 attached to the flexible panel 2 when in the closed position.
  • a cap for example a screw cap
  • the panel 2 presses the seal 9 into the cut-out 37 in container 35.
  • the cap 20 and container 35 have a co-operating snap fit 38.
  • the cap 20 is pushed on to the container 35 so that the rim 36 of container 35 presses sealingly into the seal 9 in the groove 33, and is maintained in that position by the snap fit 38.
  • the seal 9, which continues over the flexible panel 2 thus co-operates with and seals against the cut-out 37 in the wall of the container 35 when the flexible panel 2 is in the closed position.
  • Figure 11 shows a similar type of closure, with the seal 9 attached to the container instead of the flexible panel 2.
  • the connection between the cap 20 and container 35 is effected by ultrasonic welding at 39, or by adhesive or sealant.
  • a metal-loaded plastic sealing ring may be incorporated, which is melted by the application of radio frequency energy to join and seal the two parts.
