- ABSTRACT [51 Int. Cl B32b 31/20 Material for p liners the form of a Sandwich and 53 Field f Search u 1 1/42 43 211 242 252 so arranged that a compressible intermediate layer of 1 1/253 401; 215 40 43 R relatively great thickness is disposed between two .relatively thin non-resilient layers.
- the intermediate layer 5 References Cited can be squeezed beyond the periphery of the material for makmg a better Sal.
- liners are employed to seal the contents of the container 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 and material used for liners therefor have been a compromise between the requirement that the liner material be stress and crack resistant while also being moisture impervious and impervious to chemicals and acids, yet being bendable and compressible enough to provide for an effective seal.
- the present invention oversomes the difficulties of the prior art liner material and has all of the advantages of these prior materials without the corresponding disadvantages.
- a further advantage of the liner according to the present invention is that liners are capable of being stamped out of stock liner material without freezing.
- One of the features of the invention resides in liner material capable of forming a liner that 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 side walls of the cap for making a most effective seal.
- a further object of the invention resides in the production of a liner material that is capable of being extruded as a multi-layer sandwich.
- FIG. 1 is an exploded sectional detail view illustrating the cap and liner therefor made from liner material according to the invention
- 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 portion of the cap and liner therefor as firmly secured on a container;
- FIG. 4 is a partial sectional view of the linermaterial
- 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;
- FIG. 6 is a sectional view of a modification
- FIG. 7 is a sectional detail view of a modified form of liner material.
- reference numeral 10 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 side walls 18 which are internally threaded at 20 and atop 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 be threadedly secured on the neck 12 with the threads 20 engaging the threads 14.
- the liner 26, see FIG. 4, is from a liner material in accordance with the invention formed of a sandwich of outer layers 28, and 30, and an innerlayer 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 non-resilient, impervious and is extruded in a very thin layer in the order of approximately 1 /2 one-thousandths of an inch.
- the intermediate layer 32 is a thermoplastic 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 28 and 30.
- the outer layers 28 and 30 are extruded at a temperature approximately 300 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 dye and at about 300 F for bonding within the combination dye.
- 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.
- the intermediate layer 32 be between 12 to 30 times the normal width of each of the outer layers 28 and 30.
- FIGS. 6 and 7 there is shown a modified form of the invention wherein a two-ply liner is used.
- the cap has its top 122 serve as the upper outer liner, there being only an intermediate liner 132 and a lower outer liner 130.
- outer layers being relatively thin and non-resilient, said intermediate layer being resilient, compressible, and relatively thick, said outer layers being of low density polyethylene, said intermediate layer being of an ethylene vinyl acetate copolymer, said intermediate layer being from 12 to 30 times the thickness of said outer layers.
