Definitions
- the present invention relates generally to a container closure and particularly to a snap-on closure which is snapped on/pushed on to a container opening.
- a conflicting requirement for snap-on closures is that they should not be too difficult to open and yet the means for lifting the closure off the container should not project excessively from the closure body.
- a snap-on container closure comprising a body having a pull member of removing at least part of the closure, the pull member being movable from a stowed position to a deployed position.
- the present invention therefore provides the possibility of a pull member which can extend considerably from the main body when required, but can be transported and supplied in a more compact form with the pull member in a stowed position.
- the pull member may comprise a ring pull or the like structure.
- a ring pull can be easily grasped by a user in order to remove the closure and this allows the closure to be formed with a strong and stable connection to the container which is not overly difficult to overcome using a ring pull.
- the pull member may be formed, for example by moulding, in the deployed position or in the stowed position or in a position intermediate the stowed and deployed positions.
- the pull member may be formed in the deployed or intermediate position and moved to the stowed position post-production ready for transport or storage.
- the pull member may be formed so that it is folded out from the stowed to the deployed position in use.
- the member may, for example, be joined to the body by a hinge, such as a film or snap hinge.
- the closure may be replacably removable from the container.
- the body comprises a stopper member which can be replaced on to a container if required.
- the body may comprise a sidewall that includes a snap-on band for pushing onto a container neck bead.
- the hoop strength of the band may be broken when the closure is opened for the first time.
- the pull member may cause part of a snap bead to be torn out of the main body.
- the closure may be formed from a thermoplastics material, for example polypropylene or polyethylene.
- a thermoplastics material for example polypropylene or polyethylene.
- a single-serve beverage container closure comprising a snap-on body formed from a thermoplastics material.
- This aspect of the present invention therefore has particular application for single-serve beverage containers.
- a container which has an individual serving of product, for example a 330ml beverage bottle.
- the closure By forming the closure to be snap- on/push-on it becomes technically easier to reduce the size of the closure and the amount of material used when compared to screw-on closures.
- Any suitable thermoplastic material may be used, for example, polypropylene or polyethylene.
- the body may comprise a stopper member. This means that following first opening the closure can be replaced on to the container to close it if the entire beverage has not been consumed.
- the body may comprise a pull member for removing at least part of the closure from a container in use. For example, a pull tab or the like may be provided for lifting the closure body off the container.
- the body may be formed in such a way that upon first opening its structure is changed so that it can no longer function as a complete closure. This may, for example, be used in conjunction with a body having a stopper member so that the closure can be replaced in its altered form and still function as a stopper.
- the body may comprise a sidewall that includes a snap-on band that allows it to be push fit onto a container neck bead. The hoop strength of the snap-on band may be broken when the closure is opened for the first time.
- the band may be a turned-in band, part of which is formed by a pull tab that is torn upon first opening.
- a plastics snap- on cap for a single-serve beverage container.
- a snap-on container closure comprising a body formed from a thermoplastics material and having a snap-on band for pushing onto a container neck bead, the hoop strength of the band being breakable as the closure is opened for the first time.
- the present invention also provides a container having a closure as described herein.

- Figure 31 is a rear perspective view of the closure of Figure 30. Referring first to Figures 1 and 2 there is shown a snap-on closure generally indicated 10 attached to a container generally indicated 15.
- the closure 10 comprises a body with disc-shape top plate 20 and a generally cylindrical sidewall 25 which depends from the periphery of the top plate 20.
- the closure 10 is firmly retained on the container 15 by a snap bead (not shown) which projects inwardly from the free end of the sidewall 25 and engages on a corresponding retention bead (not shown) on the container neck.
- a ring pull member 30 is provided in order to be able to overcome the resistance provided by the beads on the closure and the neck.
- the ring pull 30 is shown in a stowed position in which it is folded onto the top plate 20 and fits within a recess.
- the ring pull 30 is connected ⁇ o the sidewall 25 by a hinge 35.
- the hinge 35 allows the ring pull 30 to be moved from the stowed position shown in Figure 1 and 2 to a deployed position as shown in Figures 3 and 4 in which it is folded approximately 180° out from the closure body as shown by the arrow A.
- the recess in the top plate 20 formed by a raised peripheral wall 40 can now be seen.
- hinge 35 and ring pull 30 are configured so that the ring pull can be locked in the deployed position.
- FIG. 5 to 8 there is shown a closure 1 10 formed according to an alternative embodiment.
- the closure 1 10 is very similar to the closure 10 shown in Figures 1 to 4.
- the closure 1 10 is moulded from a thermoplastics material and is moulded with the ring pull member 130 in the position shown in Figures 1 to 8, that is approximately orthogonally to the plane of the closure. After the closure 1 10 is removed from the mould the ring pull member 130 is folded down into the recess provided by the wall 140 so that it can easily be transported and stored with the ring pull member in a stowed position.
- Figure 9 there is shown a closure 210 formed according to an alternative embodiment.
- the closure 210 is shown connected to a container neck.
- the free end of the closure sidewall 225 is provided with a snap bead 245 which allows the closure to be push-or snap-fit onto the container neck, which is provided with a retention bead 250.
- the closure 210 is shown in an as-moulded condition, in which the ring pull member 230 is formed in the deployed position shown in Figure 9.
- FIG. 10 there is shown a closure 310 formed according to an alternative embodiment.
- the closure 310 is very similar to the closure 210 shown in Figure 9.
- an annular stopper 355 is provided and depends from the interior of the top plate 320.
- the stopper 355 is dimensioned to fit sealingly within the container neck mouth 360 and allows the closure to re-seal the mouth 360 after first opening.
- FIG. 1 1 to 19 there is shown a closure 410 formed according to an alternative embodiment.
- the closure 410 is shown connected to a container neck 460, but with the container shown removed for ease of reference.
- the closure 410 is similar to the closure 1 10 shown in Figures 5 to 8 and accordingly comprises a sidewall 425 and a ring pull 430 connected together by a hinge 435.
- the sidewall 425 is generally cylindrical and includes an annular snap bead 445 extending around the inside for snap engagement under the container neck retention bead 450.
- the snap bead 445 is continuous except in the region of the hinge 435 where a disconnected bead member 446 is provided that is separated from the bead by a gap 447 either side as best shown in Figures 16 and 17.
- a short annular platform 468 At the opposite end of the skirt 425 to the bead 445 a short annular platform 468 extending radially inwardly.
- annular plug 465 depends and an annular turret 470 projects.
- the underside of the platform 468 also includes an annular projection 475 spaced radially outwardly from the plug 465 by a distance such that the projection 475 and plug 465 are spaced to fit either side of the container neck mouth.
- the turret 470 comprises an annular top plate 471 and a cylindrical inclined sidewall 472 depending from the periphery thereof and connecting to the platform 468.
- the exterior face of the sidewall 472 is provided with a plurality of circumferentially spaced lugs.473 as shown best in Figures 18 and 19.
- the ring pull 430 is shown in a stowed position.
- the ring pull 430 comprises a flat annulus connected at one side to the hinge 435. Opposite the hinge 435 the ring pull 430 is provided with a peak 431 to facilitate lifting of the ring pull as described in more detail below.
- the annulus of the ring pull member is dimensioned so that it fits around the turret 470 and engages the lugs 473 with a friction fit to hold it in position.
- the hinge 435 is generally strap-like and C-shape with a first connector portion 436 joined to the ring pull 430, a second connector portion 437 joined to the open end of the sidewall 425 and the connector pieces 436, 437 being joined by a convexly curved link 438.
- the section of the sidewall 425 to which the connector 437 is joined is flanked by two thinned regions 426 which form lines of weakness as described in more detail below.
- the closure 410 is assembled onto a container neck 460 by pushing it axially onto the neck so that the beads 445, 446 snap engage underneath the retention bead 450.
- the plug push fits into the container mouth to form a seal.
- the ring pull 430 is lifted up using the peak 431 and away from the turret 470. Pulling on the ring pull 430 will cause tearing of the sidewall 425 along the lines of weakness 426 as shown in Figures 18 and 19.
- the closure can be pulled off the container neck by pulling further on the ring pull 430.
- the closure can be replaced on the container neck 460 to reseal the container if required by pushing the closure 410 back down onto the neck so that the plug 465 reengages in the container neck mouth.
- the bead 445 will re-engage under the bead 450 but the bead 446 will not and combined with the released hoop strength of the sidewall 425, replacing the closure on the container neck is not made unduly difficult.
- FIG. 20 to 25 there is shown a closure generally indicated 510 shown attached to a container neck generally indicated 515.
- the closure 510 comprises a generally circular top plate 520 and a generally cylindrical sidewall (or band) 525 which depends from the periphery of the top plate 520. Because the closure uses a snap-on engagement this allows the sidewall to be relatively shallow.
- a curved, generally semi-circular pull tab 530 depends from the free end of the sidewall 525.
- the container neck 515 forms part of a container for a single-serve beverage.
- the container (not shown) is intended to accommodate volume of approximately 330ml.
- different container volumes are possible, with the intention being that the container is formed and marketed to provide a single serving of product.
- a snap bead 535 is provided at the free end of the sidewall 525 .
- the bead 535 is a continuous annular projection.
- annular stopper 540 depends from the underside of the top plate 520 .
- the stopper 540 is dimensioned to fit tightly within the container neck mouth.
- the pull tab 530 is grasped by a user and pulled upwards as shown by the arrow A. This causes tearing of a section of the sidewall 525 best illustrated by the dotted lines 545 in Figure 22. By removing the section of the sidewall 525 in this wall the hoop strength of the sidewall is removed. Thereafter the closure 510 can be pulled off the neck 515 using the tab 530 in the direction illustrated by the arrow B.
- the closure 510 can be replaced onto the neck 515. In doing so, the stopper 540 re-engages into the container mouth to provide a temporary seal.
- the closure does not completely re-engage the neck, but does function as a stopper.
- FIG. 26 there is shown a closure 610 fitted to the neck 616 of a single- serve beverage container 615.
- the closure 610 comprises a sidewall 625 and a ring pull 630 connected together by a hinge 635.
- the sidewail 625 is generally cylindrical and includes an annular snap bead (not shown) extending around the inside for snap engagement under a container neck retention bead (not shown).
- the snap bead is continuous except in the region of the hinge 635.
- At the closed end of the skirt 625 a short annular platform 668 extending radially inwardly to form a step with an annular turret 670 projecting from its centre.
- the turret 670 comprises an annular top plate 671 and a cylindrical sidewail 672 depending from the periphery thereof and connecting to the platform 668.
- the ring pull 630 is shown in a stowed position.
- the ring pull 630 comprises a flat annulus connected at one side to the hinge 635.
- the ring pull 630 is provided with a peak or "hood" 631 to facilitate lifting of the ring pull as described in more detail below.
- the annulus of the ring pull member 630 is dimensioned so that it fits tightly around the sidewail 625.
- the hinge 635 is generally strap-like and is joined to the ring pull 630 and also to the open end of the sidewail 625.
- the section of the sidewail 625 to which the hinge is joined is flanked by two thinned regions 626 which form lines of weakness as described in more detail below.
- the closure 610 is assembled onto a container neck 616 by pushing it axially onto the neck so that the co-operating snap beads engage. An internal plug push fits into the container neck mouth to form a seal.
- the ring pull 630 is lifted up using the peak 631 and hinged away. Pulling on the ring pull 630 will cause tearing of the sidewall 625 along the lines of weakness 626. The closure can then be pulled off the container neck by pulling further on the ring pull 630.
- the closure can be replaced on the container neck 616 to reseal the container if required by pushing the closure 610 back down onto the neck so that the internal plug re-engages in the container neck mouth.
- the ring of the pull member can be pushed back down and over the sidewall. Because the ring extends around the sidewall it can act like a belt to re- tighten the engagement of the closure on the neck. This principle could, of course, be used in combination with other aspects and embodiments of the invention.
