Disposable can

Abstract

“The invention relates to a disposable can formed at least partly by flexible film material, wherethe can includes a top surface and where the can has at least one discharge arrangement having at least one re-closure foundation and where the discharge arrangement is attached to the cansuch that a drinking can may advantageously be formed by film material, where the can may advantageously be suitable for use in the same way as conventional cans made of solid walls and at the same time be manufactured in a very cost-efficient way, and the can may be disposed in a very environmentally friendly way.”

Description

TECHNICAL FIELD OF THE INVENTION[0001]The invention relates to a disposable can.BRIEF DESCRIPTION OF RELATED ART[0002]Different attempts in the prior art have been made to apply film-based packages in connection with e.g. distribution of carbonated or non-carbonated beverages.[0003]U.S. Pat. No. 5,833,368 discloses a beverage container which is made by film material. The container comprises a discharge system which involves a pull tab system covering a straw input area.[0004]International patent application WO 01185560 discloses a further container which is a stand-up bag of heat-sealable plastic film. The container is applied for containing flowable products.[0005]The above documents suffer from the disadvantage that the discharge systems are either not suitable for drinking per se, i.e. requires further discharge elements such as a straw, or that drinking directly from the beverage is inconvenient compared to conventional discharge arrangements such as bottles, cans or glasses in ...

AI Technical Summary

Benefits of technology

[0010]Moreover, the can according to the invention may be easily collapsed and handled after use during disposal.

[0159]In an embodiment of the invention, the can comprises a re-closure comprising cutting, pressing or perforation means. These means may allow an easy opening of the further sealing of the can. On embodiment of the re-closure may comprise a slightly inclined downwardly oriented surface or edge, which may break the further sealing when the re-closure is actuated, e.g. by screwing or pushing in the opposite direction than the screwing movement applied during removal of the re-closure. In other words, the re-closure may be applied alone or in conjunction with the re-closure foundation as a tool for opening the further sealing.

Problems solved by technology

The above documents suffer from the disadvantage that the discharge systems are either not suitable for drinking per se, i.e. requires further discharge elements such as a straw, or that drinking directly from the beverage is inconvenient compared to conventional discharge arrangements such as bottles, cans or glasses in the sense that the container itself comprises integrated discharge arrangements such as a pipe-like output from which a user may drink directly.

A further problem related to the above mentioned discharge arrangement is that re-closure is impossible or un-reliable.

It is noted that that a re-closure is quite attractive with respect to can structures but such re-closures are generally expensive and difficult to produce both with respect to fastening and with respect to compatibility of materials.

It is a known problem that the water in parts of the world is polluted, e.g. by health threatening organisms, bacteria, minerals, toxics, dangerous metals or the like.
