Definitions

  • This invention is a sealing unit for re-sealing the conventional type of 'Ring Pull' drinks can.
  • EP 0934 887 A further example which is typical of the art can be found in EP 0934 887 where particular attention has been paid to the design of the inner surface of the sides of the cap in order to ensure a better grip between the cap and the can. Though, in the same way as in previous art it is still necessary to rely on the ability of the cap to grip onto the raised rim at the top edge of the drinks can.
  • This European patent also takes the art a stage further however by providing a re-sealable exit for the liquid inside of the can so as to eliminate the need to remove the cap before taking a drink from the can.
  • a sealing unit for drinks cans consisting of a driving member, a driven member, a compression washer and an expanding seal. These elements being assembled together such that the driving member applies force to the driven member. Such force is maintained either by continuous pressure from the driving member onto the driven member or by rotating the driving member along a screw thread of suitable pitch formed between the driving member and the driven member. Pressure applied to the driven member is transferred directly to the compression washer. As the pressure on the compression washer is increased, the distance between the driving surface of the driving member/compression washer and the distal end of the driven member is reduced, thus compressing the expanding seal. If this action takes place when the expanding seal is placed into the open hole in a drinks can then the expansion seals the hole in the drinks can both from above and below thus preventing the escape of gas from the can.
  • the compression washer could be shaped with a tapered neck extending down from the underside of the compression washer into the expanding seal.
  • Fig.1 Is an illustration of a standard drinks can
  • Fig 2 Is a threaded cap driven sealing unit where 2/1 is the driving member, 2/2 is the driven member, 2/3 is the compression washer , 2/4 is the expanding seal.
  • Fig 3 l a wing nut driven sealing unit where 3/7 is the driving member
  • 3/8 is the driven member, 3/3 is the compression washer and 3/4 is the expanding seal.
  • Fig 4 Is an alternate threaded cap sealing unit where the thread diameter is smaller than Fig 2.
  • 4/9 is the driving member
  • 4/8 is the driven member
  • 4/3 is the compression washer
  • 4/4 is the expanding seal
  • Fig 5 Is a further sealing unit with a clamp lever action in which 5/5 is the driving member, 5/6 is the driven member, 5/3 is the compression washer and 5/4 is the expanding seal.
  • Fig 6 Is a further sealing unit of different construction to the previous example where 6/10 is the driving member, 6/11 is the driven member, 6/3 is the compression washer and 6/4 is the expanding seal.
  • Fig 7 Shows the compression washer.
  • Fig 8 Shows an alternate view of the compression washer 3 and the expanding seal 4.
  • This invention relates to a sealing unit for a drinks can such as the can 12 shown in Fig 1.
  • These cans typically have a ring pull 1/13 which is pulled upwards breaking off a section of the can 1/14, leaving a hole at 1/14. In some cans the ring pull is retained and in others it is removed completely. It is desirable in the case of the current invention if the ring pull is removed from the can completely, even with those cans intended to retain the ring pull.
  • the invention can be brought into use by placing it on the top of the can 12 and inserting it through hole 14.
  • the distal end of the driven member 2 together with the distal end of the compression washer 4b both extend through the hole 14 in the can. The unit would then come to rest with the shoulder of the compression washer 4a resting on the top of the can.
  • the compression washer 3 which is shown in greater detail in Figures 4 and 7 is arranged so that its curved edge is aligned with the curvature of the top of the can 12.
  • a trough extending around the whole of the inner periphery of the top edge of the can. This trough has the appearance of a recess and is a by product of the forming process during manufacture of the can.
  • the protrusions 3a formed on the compression washer 3 will fit into the cans peripheral recess thus assisting retention of the unit in the correct position on the top of the can.
  • pressure is applied to the compression washer by rotating the driving member 1 on the screw thread which coexists between the driving member 1 and the driven member 2 causing the shoulders 1a to apply pressure to the compression washer 3.
  • the distance between the shoulders 1a and the distal end of the driven member 2a is reduced thus compressing the expanding seal 4.
  • the expanding seal 4 maybe assisted by the compression washer, which can be equipped with a conical flange 3a designed to enter the expanding seal 4 and assisting in its expansion.
  • the expanding seal 4 deforms in a number of directions but essentially it expands to fill the hole 14 in the drink can. It becomes a barrel shape inside the can where the waist of the barrel grips the underside of the hole 14. A seal is therefore formed in three ways.
  • FIG. 3 Another form of seal is shown in Fig 3 which operates exactly the same as the previously described seal in Fig 2.
  • the diameter of the threaded portion of the driven member 8 is narrower than that shown in the Fig 2 example.
  • the driving member 7 is differently shaped but such shape is not restricted to that shown in Fig 3.
  • a similar arrangement to Fig 3 is shown in Fig 4, again illustrating a differently shaped driving member 9, and a differently pitched thread on the driven member 8.
  • FIG. 5 A further arrangement is shown in Fig 5 in which the driving member 5 is a lever which pivots on a bearing contained in the top of the driven member 6. Fliping the lever 5 over through 180 caused the surface 5a to bear on the compression washer 3 thus achieving the same compression action as in the previous examples.
  • FIG 6 A final example is shown in Fig 6 which still retains the same compression principal but in this case the turning action to achieve the pressure is achieved by rotating the driving member bring the driven member 11 to bear on the compression washer 3 but in this case the driving member 10 itself extends downwards through the expanding seal 4.
  • a further version of the sealing unit is intended wherein there is incorporated a provision for storage of the can seal after it has been broken from the can.
