Definitions
- 215/40 liner is formed of a sandwich and so arranged that a com- [5 I] Int. Cl. 865d 53/04 pressible intermediate layer can be squeezed beyond the nor- [50] Field of Search 215/40, 43 mal periphery ofthe liner to engage the cap and make a better R seal.
- This invention relates to a liner for a cap and to a combination cap and liner for use in providing closures for containers such as bottles, tubes, cans, and the like.
- cap constructions utilizing liners have been devised in the past. These liners are employed to seal the contents of the container 7 preventing leaking between the threaded portions of a container neck and the cap by providing for a positive seal at the mouth of the container.
- Such previous cap constructions and liners therefor have been a compromise between the requirement that the liner be stress and crack resistant while also being moisture impervious and impervious to chemicals and acids yet being bendableand compressible enough to provide .for an effective .seal.
- the present invention overcomes the difficulties of the prior art caps and seals and has all of the advantages of these prior devices without the corresponding disadvantages while providing for satisfactory seal.
- A, further advantage of these liners is that they are capable of being stamped out of stock without freezing.
- One of the features of the invention resides in a cap and liner combination in which the liner is freely rotatable within the cap until such time as the mouth of the container is firmly against the liner compressing the liner so that an intermediate layer of the liner is compressed and expands outwardly thereby abutting against the sidewalls of the cap for making a most effective seal.
- Still further objects and features of this invention reside in the provision of a cap and liner therefor that is capable of being extruded by conventional combination discs and which can be conveniently stamped to shape thereby permitting manufacture at a relatively low cost, and which is highly effective in use.
- FIG. 1 is an exploded sectional detail view illustrating the cap and liner therefor;
- FIG. 2 is a sectional detail view showing the cap liner therefor in a stage of being secured on the neck of a container;
- FIG. 3 is an enlarged vertical detail view illustrating a pot tion of the cap and liner therefor as firmly secured on a container;
- FIG. 4 is a partial sectional detail view ofthe liner
- FIG. 5 is a view similar to FIG. 4 but showing the shape of the liner after it has been compressed when the cap has been tightly closed on the container.
- reference numeral is used to generally designate a conventional container such as a bottle, tube, or can having a neck 12 which is threaded at 14.
- a cap 16 is employed which includes cylindrical sidewalls 18 which are internally threaded at 20 and a top 22.
- a cylindrical groove 24 is formed as the uppermost of the threads 20 and is for the purpose of receiving therein a liner 26.
- the cap 16 is preferably molded out of any suitable synthetic plastic material and is adapted to gaging the threads 14.
- the liner 26, see FIG. 4, is formed of a sandwich of outer layers 28, and 30, and an inner layer 32, the liner 26 preferably being stamped in the shape of a disc.
- the outer layers 28 and 30 are formed of a low density polyethylene, such as that sold under the trademark Alathion 20. This material is stress resistant, crack resistant, relatively nonresilient, impervious and is extruded in a very thin layer in the order of approximately 1 V2 one-thousandths of an inch.
- the intermediate layer 32 IS a thcrmoplastlc rubber like material such as butylene in polyethylene known as pliothene, or other resilient material such as ethylene vinyl acetate or the material sold under the trademark Karton, which is a thermoplastic rubber.
- this material is resilient though not necessarily as resistant to stress and cracks/or as impervious to foreign substances as the material of the outer layers 28and 30.
- the outer layers 28 and 30 are extruded at a temperature approximately 300 F. to 400 F. while the intermediate layer 32-.is extruded at approximately 220 F. to 320 F.
- the various layers are brought together within a combination die and at about 300 F. for bonding within the combination die.
- the resultant sheet material has a much increased resistance to distortion or stress, can be stamped without freezing and is impervious to chemicals and acids as well as moisture.
- a closure device comprising a cap having a top and an internally threaded cylindrical sidewall, said sidewall having a groove therein adjacent said top, a liner normally rotatably disposed in said groove and including a disc having a pair of outer layers and an intermediate layer sandwiched between said outer layers and bonded thereto, saidouter layers being relatively thin and nonresilient, said intermediate layer being resilient and being compressible to form a lip extending beyond the periphery of said outer layers and into engagement with said sidewall in said groove, said intermediate layer being relatively thick.
- a closure device according to claim 1, wherein said intermediate layer is from 12 to 30 times the thickness of said outer layers.
