Pressing bottle with bag

Abstract

The invention discloses a pressing bottle with a bag. The pressing bottle with the bag comprises the inner bag, a bottle body and a pump head connected with the bottle body; the inner bag is positioned in the bottle body; an opening of the inner bag is connected with an opening of the bottle body; a through hole communicating with the outside is formed in the bottle body; the minimum elastic modulus of the material of the bottle body is not lower than 850 MPa, and the material of the inner wall of the bottle body is not bonded with EVOH; the inner bag comprises an EVOH layer and an LDPE layer;the EVOH layer and the LDPE layer are bonded through an adhesive; the EVOH layer is positioned on the outermost side of the inner bag; and the air does not enter the inner bag from outside the bottlebody during the processes of the pressing and the rebounding of the pump head. The pressing bottle with the bag is less in using residue and good in user experience; contents in the bottle can be isolated, the quality of the contents is improved, and the shelf life of the contents is prolonged; the design is unique, the structure is simplified, the cost is low, the shape and the size of the bottle body are controllable, and the bottle body is attractive and elegant; and after the pressing bottle is used, the bottle body is separated from the inner bag, no content residue exists in the bottlebody, and the bottle body can be directly recycled, so that the energy is saved, the environment is protected, and the pressing bottle has great application prospects.

Description

technical field [0001] The invention belongs to the technical field of packaging, relates to a press bottle with a bag, in particular to a press bottle with a bag which has less residue, can isolate the content in the bottle and has a simple structure.
