Rechargeable and resealable container for e.g. corrosive liquids - is liner of suitable chemically resistant polymer which fits into container, with spout fitting into mouth and sealed after each use

摘要

A liner is inserted into containers for chemicals which can be e.g. only partially emptied, and partic. into cans or bottles. It consists of a plastic bag whose dimensions at least equal those of the interior of the containter. This bag has a tubular part whose dimensions fit those of the neck/mouth of the container. The bag is pref. made of polyethylene, PVC or polyamide. The inner liner (1) is a plastic bag, of size conveniently fitting inside the outer container (2). The bag (1) has a spout (3) where suitable for the end prod. The bag (1) is 50-200 micrometers thick. Polyethylene is a pref. material as this fits itself to the container contours and is easily cleaned. The container (2) can have a 2nd opening e.g. to allow air to escape from the liner. The spout (3) can have a welded ring (9) resting against the neck or it can be sealed off e.g. by a plug or screw top etc. ADVANTAGE - The liner solves the problems of having a container for e.g. corrosive liquids, which can be completely refilled and again sealed off. It eliminates problems of air pockets inside or between the liner and the outer container.
