Embodiment Construction

[0015] figure 1 Shown is a container 10 having film-shaped materials 30 arranged in a stack therein with a separator material 40 sandwiched between them.

[0016] The container 10 is, for example, a box, a foil bottle, etc., made of plastic, glass or other material that does not absorb the fragrance or the active substance of the film-like material 30 . figure 1 The illustrated cartridge 10 is, for example, a parallelepiped. It includes, for example, a housing 11 and a cover 12 that can be folded and opened. In this embodiment, the cover 12 is connected to the housing 11 by a film hinge 13 . The cover 12 can also be designed as a sliding cover, a removable cover, and the like. The corners and edges of the box 10 are for example rounded. When the lid 12 is closed, the box 10 is, for example, as sealed as possible against the penetration of impurities. If necessary, additional sealing elements can be provided on the lid 12 and / or the housing 11 in order to close the box 10 ...

Abstract

The packaging unit comprises a container (10) and film-like materials (30) which are hygroscopic or become soft in the presence of moisture. The film-like materials are stacked in the container, and achemically inert and physically durable separating material (40), such as a PET film, is arranged between them. Each separating material makes contact with two respective film-like materials. The separating material does not adhere to one of these film-like materials, or at least less strongly than it does to the other film-like material.

Description

technical field [0001] The present invention relates to a packaging unit comprising a container and a film-like material which is hygroscopic or softens when wet. Background technique [0002] Hygroscopic film-like materials are, for example, edible films, strips or flakes which are used, for example, as pharmaceutical, confectionary, cosmetic and oral hygiene products. They are, for example, rapidly soluble in water and soluble in saliva. And most of them are composed of hydrophilic and hygroscopic matrix polymers such as starch or polysaccharides of the cellulose family, polyvinylpyrrolidone, polyvinyl alcohol and pullulan. They are highly hydrophilic and eager to absorb water. When used in the mouth, this results in rapid dissolution, however, during storage a large amount of water is absorbed from atmospheric humidity. The film-like material has a minimum moisture content of 5% by weight relative to water. At lower moisture contents it may become brittle. At moistur...
