Abstract
An adhesive is described. The adhesive is formulated from one or more organic components that have FDA approval.
Description
- The present invention relates to an adhesive.
- It is known to use adhesives to prepare containers for foodstuffs, such as foods and beverages. For example, it is known to use an adhesive to adhere a coated aluminium pressurised gas container to the inner surface of the base of a can, especially when that can is for containing beer. Pressurised gas containers are generically called “widgets”. Teachings on widgets may be found in British patent application No. 90/06731.7.
- Another example of the use of adhesives in preparing containers for foodstuffs may be found in U.S. Pat. No. 5,370,941 which describes a laminated film comprising a base resin layer, a barrier layer and an adhesive layer. The adhesive layer is made from a blend of ethylene, alkyl (meth)acrylate, a copolymer of propylene and ethylene, and other ethylene impact copolymers.
- We now recognise that some adhesive components may leak into, and thereby contaminate, foodstuffs contained in containers. This, in turn, could make the foodstuffs unpalatable or, just as importantly, not suitable for consumption, in particular human consumption.
- The present invention seeks to overcome this problem.
- According to a first aspect of the present invention there is provided an adhesive formulated from one or more organic components that have FDA approval.
- According to a second aspect of the present invention there is provided a container for a foodstuff comprising at least two parts joined together by an adhesive, wherein the adhesive is formulated from one or more organic components having FDA approval.
- Some or all of the at least two parts may be parts of a common single body or different bodies. Some or all of the at least two parts may be edges of a common single body, for example the edges of a container, preferably a can.
- According to a third aspect of the present invention there is provided a container for a foodstuff having held inside a body, wherein the body is adhered to at least a part of at least one inner wall of the container by an adhesive, wherein the adhesive is formulated from one or more organic components having FDA approval.
- The adhesives of the present invention are advantageous in that any leakage of the adhesive component(s) into the foodstuff contained in the container would not make the foodstuff unsuitable for consumption, in particular human consumption.
- Thus, the present invention is based on the surprising finding that it is possible to formulate an adhesive composition for use in preparing a container for foodstuffs (such as a beverage) wherein the adhesive is formulated from organic components that have FDA approval.
- The term “that have FDA approval” means that the components do have or can have or would have (such as in the future) FDA approval.
- The term “wall” includes any side wall, base portion or top portion.
- The adhesive composition of the present invention is an adhesive in that it is a non-metallic substance capable of joining materials by surface bonding (cohesion) and the bond possessing adequate internal strength adhesion. This definition is in accordance with the definition of “adhesive” presented in the February 1996 version of the draft European standard booklet EN 923:199X as compiled by the European Committee for Standardisation.
- The adhesive composition does not primarily serve as a functional barrier between food and a substrate.
- The adhesive is formulated solely from one or more organic components that have FDA approval. This means that the adhesive does not contain organic components that do not have FDA approval.
- Preferably, the adhesive further comprises one or more inorganic inert filler components. These inert filler components may have FDA approval.
- In a highly preferred embodiment, the adhesive is not water soluble.
- The adhesive compositions can be tailored to cure as quickly or slowly as desired, such as by the addition of suitable and acceptable catalysts etc. or even varying the temperature of application and/or for curing.
