Embodiment Construction

[0047] Embodiments of the present invention will be described below. Various characteristic items shown in the embodiments shown below may be combined with each other. Moreover, each feature independently establishes the invention.

[0048] Such as Figure 1 ~ Figure 2 As shown, a laminated peel container 1 according to an embodiment of the present invention includes a container body 3 and a valve member 4 . The container main body 3 includes a storage portion 7 for storing the contents, and a mouth 9 for discharging the contents from the storage portion 7 .

[0049] Such as figure 2 As shown, the container body 3 is provided with an outer layer 11 and an inner layer 13 in the accommodating portion 7 and the mouth portion 9 , the outer layer 11 constitutes the outer shell 12 , and the inner layer 13 constitutes the inner bag 14 . As the content decreases, the inner layer 13 is peeled off from the outer layer 11, and the inner bag 14 is peeled off from the outer shell 12 t...

Abstract

Provided is a delamination container which is excellent in each of squeezability, drop breaking resistance, and water vapor impermeability. The present invention provides a delamination container (1)provided with a container body (3) having an outer shell (12) and an inner bag (14), the inner bag (14) contracting in conjunction with a reduction in contents thereof, wherein an inner layer (13) constituting part of the inner bag (14) includes a mixed resin layer configured from a mixed resin containing a cycloolefin polymer and a styrene-based thermoplastic elastomer.

Description

【Technical field】 [0001] The present invention relates to laminate peel containers. 【Background technique】 [0002] There are known laminated peelable containers having an outer shell and an inner bag and having a container main body in which the inner bag shrinks as the content decreases (for example, Patent Documents 1 to 2). [0003] [Prior Art Literature] [0004] 【Patent Literature】 [0005] [Patent Document 1] Japanese Patent Laid-Open No. 2005-75414 [0006] [Patent Document 2] Japanese Patent No. 3650175 【Content of invention】 [0007] 【Problems to be solved by the invention】 [0008] (1st point of view) [0009] Such a laminated peel-off container is sometimes required to have a small squeezing force (squeezability) when the contents are discharged, and it is difficult to break when the container is dropped (drop crack resistance), so that water vapor is difficult to permeate (water vapor non-toxicity). permeability) etc. The inner bag of the laminated peel...
