Abstract
Disclosed is a metal bottle seal that is disposed on the curl of the metal bottle. The bottle seal may be held in place by crimping of the curl. In addition, adhesive may be used to hold the bottle seal on the curl. Adhesives can be used that fill discontinuities that may exist in the curl as a result of substantial drawing and ironing of the metal. Further, the metal bottle seal can be made of a material or laminated with a material that is soft enough to fill the discontinuities. The seal can be preformed as a continuous annulus for easy application to the top of the metal bottle. The metal bottle seal can also be used in conjunction with a cap seal to ensure an adequate and reliable seal.
Claims18
A metal bottle and sealing system structured to cooperate with a cap to retain a liquid, said cap having a distal portion and a protrusion extending therefrom, said protrusion including a threaded portion having a first diameter, wherein said metal bottle and sealing system comprises:
- a first end defining an opening structured to be sealed by said distal portion of said cap, the first end having a second diameter;
- a second end disposed opposite and distal the first end, the second end having a third diameter larger than the second diameter;
- and
- a neck portion having an interior and an exterior, said neck portion extending from the first end toward the second end,
- wherein the first end includes a curl structured to cooperate with said sealing system to facilitate sealing of said bottle opening, said curl having a fourth diameter greater than the first diameter;
- wherein said neck portion is threaded only on said interior;
- wherein the interior of said neck portion is threadably engaged with said threaded portion of said cap;
- wherein said sealing system further comprises an annular-shaped bottle seal having an inner layer and an outer layer laminated to said inner layer;
- wherein said outer layer is made of a first plastic material in order to prevent metallic taste from being transmitted from said metal bottle to a user;
- wherein said inner layer is made of a second plastic material softer than the first plastic material in order to fill discontinuities in said curl;
- and wherein said curl is structured to engage said inner layer.
A bottle assembly comprising:
- a cap having a distal portion and a protrusion extending therefrom, said protrusion including a threaded portion having a first diameter, and
- a metal bottle comprising:
- a first end defining an opening structured to be sealed by said distal portion of said cap, the first end having a second diameter,
- a second end disposed opposite and distal the first end, the second end having a third diameter larger than the second diameter, and
- a neck portion having an interior and an exterior, said neck portion extending from the first end toward the second end,
- wherein the first end includes a curl having a fourth diameter greater than the first diameter,
- wherein said neck portion is threaded only on said interior,
- wherein the interior of said neck portion is threadably engaged with said threaded portion of said cap;
- wherein said bottle assembly further comprises an annular-shaped bottle seal having an inner layer and an outer layer laminated to said inner layer;
- wherein said outer layer is made of a first plastic material in order to prevent metallic taste from being transmitted from said metal bottle to a user;
- wherein said inner layer is made of a second plastic material softer than the first plastic material in order to fill discontinuities in said curl;
- and wherein said curl is structured to engage said inner layer.
