Abstract

A beverage can is provided with an internal stopper arm 1 bearing a flexible sealing ring 5. The stopper arm is riveted to the underside of the can's top 8 at 2 such that by finder pressure the stopper arm may be swivelled about the rivet to cause the can's dispensing aperture to be sealed or unsealed as desired. A lug 6 may facilitate movement of the arm 1.

Description

IMPROVEMENT TO BEVERAGE CANS This invention relates to a re-sealable beverage can The'ring-pull'beverage can suffers from the disadvantage that it is not re-sealable; once opened any remaining contents will soon'go flat', and there is the risk of spillage.
The invention consists of an internal stopper fitted to an arm which is free to be pivoted about a fixed riveted point on the underside of the can's top such that the stopper may be moved by finger pressure to seal or unseal the dispensing aperture of the can as required.
A specific embodiment of the invention will now be described by way of example with reference to the accompanying drawings in which: Figure 1 shows in plan form the beverage can.
Figure 2 (a) and (b) show the stopper arm assembly in plan form and cross section respectively.
Figure 3 shows the stopper arm assembly fitted to the underside of the can's top.
Figure 4 (a) and (b) shows the can in sealed and unsealed mode respectively.
Figure 5 shows in cross-section an all plastics stopper arm assembly.
Figure 6 shows a modified form of stopper arm.
Figure 7 shows an anti-tamper device.
Referring to Figure 2 (a) and (b). The stopper arm assembly consists of three elements-the stopper arm 1; the stopper/button 3 (which incorporates the lug 6) and the compressible ring seal 5.
The assembly is fitted to the underside of the can's top by rivet 2 and is free to be pivoted about this point. In the can's sealed mode the stopper/button 3 occupies the dispensing aperture 4 (Figure 1) and is slightly proud of the can's top, 8. (Figure 1) Figure 3 shows in cross-section the stopper arm assembly fitted to the underside of the can's top. As with the existing'ring-pull'can the fixing ofthe rivet through the can's top does not impair the integrity of the airtight seal.
Figure 4 (a) shows the can in the sealed condition ie. with the stopper/button 3 occupying the dispensing aperture and sealing it. By the use of finger pressure on the button/stopper 3 the assembly may be moved in the direction indicated by the arrow 7, under the can's top 8, until it occupies the'open'position shown in Figure 4 (b) thus allowing the contents of the can to be dispensed. The lug 6 prevents the assembly from over-riding the dispensing aperture.
To re-seal the can, again using the button and lug, the assembly may be moved in the direction indicated by arrow 7 in Figure 4 (b) until the button occupies the dispensing aperture and seals it.
The pre-requisite of the stopper arm 1 is that it should be flexible and resilient such that when the can is in the sealed condition the flexible ring seal 5 effectively seals the dispensing aperture, without reliance on additional carbonated pressure created by the can's contents.
The stopper arm could be formed of stainless steel or other suitable metal having the above properties, with the button 3 (incorporating lug 6) formed of a rigid plastics material bonded to the stopper arm. The ring seal may be formed of a suitable soft compressible plastics material.
However, in the interest of lower production cost, it would be desirable to construct the stopper arm assembly entirely of plastics material. Figure 5 shows in crosssection the stopper arm and the stopper/button 3 moulded or pressed in one piece from a plastics material possessing the requisite flexibility and resilience; the assembly is completed by the addition of the ring seal 5.
As stated earlier, the lug 6 is provided to facilitate the moving of the stopper arm assembly from the sealed position to the unsealed position and vice versa, and to prevent the assembly from over-riding the dispensing aperture. However, Figure 6 shows a modified version of the stopper arm lwhich incorporates a spur 9. Matters are so arranged that when the arm is moved to unseal the can the stopper/button reaches the desired point then the spur is brought up against the side of the can and thus prevents further movement of the stopper arm past this point.
The modification of the stopper arm described above could allow the lug 6 to be dispensed with if desired; in which case the button 3 would be provided with a ridged and dished profile to facilitate the moving of the stopper arm assembly.
The invention provides for an anti-tamper device designed specifically for the resealable beverage can. It takes the form of a circular label 10 of paper or other suitable material, the outer edge of which is coated with a strong waterproof contact adhesive 11, except for the area adjacent to the tab 12 as shown. The label is provided with perforations 13 in the manner of postage stamps and may be removed using the tag 12. It could be printed with instructions in the use of the can and promotional material.
The re-sealable can is used as follows: 1. The label is removed.
2. The stopper button is moved clockwise to reveal the dispensing aperture.
3. The contents are partially dispensed.
4. The stopper button is moved anti-clockwise to seal the dispensing aperture.

Claims (4)

  1. CLAIMS 1. A beverage can incorporating an internal stopper arm, bearing a ring seal, which is riveted to the underside of the can's top such that the stopper arm may, by finger pressure, be snivelled about the rivet thus allowing the can's dispensing aperture to be sealed and unsealed as desired.
  2. 2. A' stopper arm as claimed in Claim 1 v/hich is so shaped as to limit the traverse of the stopper arm about the dispensing aperture, thus allowing the facilitatin@ g lug of the stopper arm to be dispensed with if desired.
  3. 3. A stopper arm as claimed in Claim 1 or Claim 2 which is made of resilient metal or resilient plastics material, or a combination of such materials, such that an adequate sealing of the can is provided without regard to the pressure renerated by the can's contents.
  4. 4. R beverage can substantially as herein described and illust rated in the accompanying drawings.
