Description

TECHNICAL FIELD

THIS INVENTION relates to a reclosable cap for a beverage container, the cap having a partially severable portion which can be severed to reveal a dispensing aperture and a movable panel selectively positionable for re-closing the aperture.

BACKGROUND OF THE INVENTION

The applicant has observed that beverage containers, especially aluminium alloy drink cans, have a cap with a partially severable portion that must be severed to reveal a dispensing aperture for dispensing the beverage therein. The severed portion cannot reclose the aperture. Many cans are designed to press the severed portions into the interior of the cans and the severed portions are not retrievable. In some known cans the severed portions can be totally removed. In some containers, a tab opener that is pivotally fixed to the cap is used to open a can by pressing against the severable portion until severed. In some other containers, the severable portion is severed by pushing in that portion.

Once opened, the dispensing apertures of these containers remain open. The opened containers allow insertion of undesirable substances such as drugs into the containers without any need to tamper with them. In addition, insects such wasps, flies and undesired objects such as dusts can find their way into the container.

Many people drink beverages directly from the aperture in the cap. Wasps, flies and other foreign matters that have entered the container after opening and left unattended, can be consumed by drinkers, or may sting to cause pain or otherwise discomfort to these people.

OBJECT OF THE INVENTION

It is an object of the present invention to alleviate or to at least reduce to a certain level one or more of the prior art disadvantages.

DETAILED DESCRIPTION OF THE DRAWINGS

Referring initially to FIGS. 1 to 7 there is shown a beverage container 10 which in this case is in the form of an aluminium alloy beverage can for a beverage such as any one of beer, carbonated drink, fruit juice and the like. It should be noted that the container 10 can also be made of steel or plastic or any material that can be formed into a can.

The can 10 has a tubular body member 12 with a top open end and a bottom end. As can be seen in FIG. 2 a base 14 is integrally formed at the bottom end to close this end, and a cap 16 is sealingly fixed to the periphery at the top open end by seaming in this case. A rim 18 is formed at the seam and a countersink 32 is formed radially inwardly of the rim 18.

The can 10 as shown is an easy open type. The cap or panel member 16 has a severable portion 20 with its severable perimeter defined by a score line 22. A ring pull tab 24 fixed to the panel member 16 by a rivet 26. The tab 24 has an outer end configured for lifting or pulling with a user's finger and an inner end extending over the severable portion 20. The tab 24 when pulled moves pivotally so that its inner end presses against the portion 20 to partially sever the portion 20 along the score line 22. The partially severed portion 20 remains connected with the main portion of the panel member 16 at a position shown as 71. Further pulling of the tab 24 would bend the severed portion 20 into the can 10 about the position 71. Thereby, a dispensing or pour aperture 38 is presented for dispensing the beverage in the can 10.

FIGS. 2 and 3 show that the panel member 16 has a post 41 fixed in the hollow section of the underside of the rivet 26. A closure member 67 in the form of a disk is rotatably mounted to the post 41. The disk 67 has a handle 49 accessible through the aperture 38, thereby allowing the disk 67 to be rotated by using the handle 49.

FIG. 4 shows the post 41 has a head 90 and a recessed section 91 to which the disk 67 is rotatably mounted. The recessed section 91 and the head 90 prevent separation of the disk 67 from the post. The rivet 26 is hollow and its top end is in the form of a cam or wedge shaped section 37. The interior of the section 37 is also wedge shaped. The inner end 29 of the post 41 is within the wedge shaped interior and this end is flared to assist retaining the post 41 in the rivet 26.

FIG. 6 shows that the handle 49 is above the top surface of the cap 16 when the severable portion 20 is pressed to the position as shown in this Figure. The handle 49 is positioned that it has minimal interference with the severing action and the disk 67 is made of a resilient material so that the handle 49 would extend through the aperture 38 when the severed portion 20 moves past the handle 49. The user can push the handle 49 to move the disk 67 to the closed position as shown in FIG. 5. FIG. 5 shows the disk 67 is in the closed position after the panel member 16 has been opened by severing the portion 20. The disk 67 has the word WIN 87 printed as one example for the promotional use of the product.

FIG. 7A shows the underside view of the panel member 16 where the disk 67 is in a the open position and the severable portion 20 is intact with the panel member 16. When the portion 20 is severed and pressed into the can 10, the handle 49 will be exposed through the so formed aperture 38 as shown in FIG. 7B. Returning to FIG. 6, the can 10 as shown is opened by severing the portion 20 which is folded down and remained attached to the panel member 16 in the position marked as 71. The handle 49 is exposed through the aperture 38.

FIGS. 8A and 8B shows another form of the closure member or disk 67. As shown in FIG. 8A, the disk 67 is circular in shape and has an outer peripheral edge 105 and a hole 52 in the disk 67 is partially covering the underside of the severable portion 20 before opening the can 10. When opening, the severable portion 20 passes through the hole 52 and the portion 20 contacts a downward curved section 172 and pivots the disk 67 to allow the handle 49 to be exposed through the dispensing aperture 38. FIG. 8B shows the disk 67 is a closed position covering the aperture 38. FIG. 13 shows that the tab 24 being lifted to sever the severable portion 20. The severed portion 20 is then folded down about the position 71. The disk 67 has a curved projection 172 positioned so that the severed portion 20 is in contact with the curved projection 172 when it is being folded. The severed portion 20 thus causes the disk 67 to rotate while it is being folded. The disk 67 is configured so that when the severed portion 20 rotates the disk 67 through a certain degrees to an open position the handle 49 is in line with the dispensing aperture 38 and due to resiliency of the disk 67 would then projects above the top surface of the panel member 16.

FIGS. 9A to 10 shows a further form of the invention. In FIG. 9A, there is shown that the panel member 16 has a score line 93 to allow the tab 24 and severable portion 20 to be totally removed from the panel member 16 when opened. An indent or stop 152 is formed in the panel member 16 to prevent the disk 67 from moving to an inaccessible position. FIG. 10 shows another rivet 132 formed with the wedge section 58 in the panel member 16 to which the post 41 is applied. In another form the post 41 is bonded to the underside of the panel member 16. FIG. 9B shows the panel member 16 after it has been opened and the disk 67 has been pivoted to close the aperture 38.

FIGS. 11 to 12 shows another embodiment of the invention. As shown in FIG. 11, the panel member 16 has a groove 34 formed in the inner wall of a countersink to receive a curved section 54 on the disk 67. The curved section 54 is configured so that it is supported in and can rotate in the groove 34 to thereby allow the user to move the disk 67 to the closing and opening positions. FIG. 12 shows the panel member 16 having a groove 47 formed on the outer wall of the countersink to receive the curved section 97 of the disk 67. The curved section 97 can rotate in the groove 47 to allow the disk 67 to be positioned for closing and opening of aperture 38. Details of the groove 34, 47 and the curved section 54, 97 are clearly shown in the enlarged views in FIGS. 16 and 17 respectively.

FIG. 14 shows another embodiment of the invention where the disk 67 is fixed between the tubular member 12 and the cap member 16. The disk 67 has an outer peripheral portion 95 to be fixed between the tubular body member 12 and cap member 16. The tubular member 12 has a turned edge 95 at said other end and the panel member 16 has a curved edge 102 configured for wrapping around the turned edge 42 and fixed thereto by a seaming process. As such, the outer edge 95 of the disk 67 is retained between the curved edge 102 and the turned edge 42, and the disk 67 is free to rotate. FIG. 15 shows the disk 67 having grooved section 5 to receive the curved section 7 on the outer peripheral portion 95 allowing the disk 67 to rotate.

Referring to FIG. 18, there is shown a closure member 67 in the form of a disk with a semi-circular shaped through hole 52 and a curved peripheral edge 54. A handle 49 is provided adjacent to the through hole 52 at a position which is slightly off centre. FIG. 19 shows an embodiment of the cap member having the panel member 16 fitted with the disk 67 shown in FIG. 18. The curve edge 54 of the disk 67 is retained in the groove 34 which is configured to allow edge 54 of the disk to be movable while being retained therein. The groove 34 is in the inner wall of the countersink 32. A strip of sealing member 178 is applied around the score line 22. Using the handle 49, the user can turn the disk 67 between the closed position and the open position. In the closed position, the sealing member 178 engages the solid section of the disk 67 and thereby seals the gap between the disk 67 and the panel member 16 adjacent to the dispensing aperture 38. As such, the flow passage through the aperture 38 is closed.

In FIG. 20, the disk 67 has a strip of sealing member 178 on the solid section thereof. The strip of the sealing member is shaped and positioned to surround the dispensing aperture 38 when the disk 67 is placed in the closed position. FIG. 21 shows the disk 67 in the open position to allow the severable portion 20 to be severed so that beverage can flow through the aperture 38 formed following severing of the portion 20. To close the dispensing aperture 38, a user simply engages the handle 49 which is now projecting through the aperture 38 and above the top surface of the panel member 16, with a finger or fingers and turns the disk 67 in a counter clockwise direction to the closed position. In this position, the through hole 52 is no longer in line with the aperture 38. Instead, the sealing member 178 is in position to surround the aperture 38 and thereby sealing the gap between the disk 67 and the panel member 16 adjacent to the dispensing aperture 38. Accordingly, the flow passage through the aperture 38 is closed.

FIG. 22 shows a closure member 67 in the form of a disk with a substantially semi-circle shaped through hole 52. The disk 67 has a curved peripheral edge 54 arranged for retention in the groove 34 in the panel member 16, tubular member 12 or between the curved edge 102 and the turned edge 42 as hereinbefore described. A contoured portion 55 is provided along the inner edge of the through hole 52. The contoured portion 55 is shaped to substantially match that along the inner edge of the score line 22. A strip of sealing member 178 is applied to the disk's top surface. The sealing strip 178 is shaped to encircle a score line 22 on a top panel member 16 (see FIG. 23). The sealing strip 178 has an enlarged sealing part 147. The disk 67 also has a handle 49 extending outwardly and an engagement projection 114 directed into the through hole 52. Referring to FIG. 23, the panel member 16 has a countersink 32 arranged with a groove 34 (see FIGS. 16 and 17) for retaining the peripheral edge 54 of the disk 67. The panel member 16 also has a score line 22 defining a severable portion 20 which is to be severed therefrom to form a dispensing aperture 38 (see FIG. 25). The score line 22 terminates at a position 71 so that when a severable portion 20 is severed along the score line 22 the severed portion remains connected to the panel member 16. A sealing pad 142 is applied at a termination point of the score line 22. The pad 142 is arranged for sealing a gap between the folded down portion 22 and the panel member 16 as shown in FIGS. 24A and 25. The panel member 16 has a rivet 26 foe rotatably supporting a lift opener 24 as aforedescribed.

In FIG. 24, the disk 67 shown in FIG. 22 is fitted to the panel member 16 shown in FIG. 23. As shown, the severable portion 20 is yet to be severed and the disk 67 is positioned so that its engagement projection 114 is under the portion 20 and the through hole 52 is in place to allow the portion 20 when severed to be folded downwardly in to the container 10. As shown in FIG. 24A, the portion 20 is severed along the score line 22 as the severed portion 20 is being folded downwardly it engages the projection 114 and causing the disk 67 to rotate in an anticlockwise direction. The handle 49 extends through the now formed dispensing aperture 38. The sealing pad 142 seals a small gap behind the folded portion 20.

When the user desires to close the aperture 38, the handle 49 is moved from one side of the aperture 38 to the opposite side. In doing so, the disk 67 rotates to the position where the sealing strip 178 is in line with the aperture 38 and seals the gap between the panel member 16 and the disk 67. The disk 67, if made of a resilient material, would apply pressure to positively seal the gap. To open the aperture 38 for dispensing beverage, the handle 49 is moved to said one side of the aperture 38 to move the disk 67 so that the through hole 52 is in line with the aperture 38 to thereby allowing a passage through the aperture 38.

Whilst the above has been given by way of illustrative example of the present invention many variations and modifications thereto will be apparent to those skilled in the art without departing from the broad ambit and scope of the invention as herein set forth in the following claims.
