Embodiment Construction

[0042] Next, an embodiment of the squeeze container 1 of the present invention will be described in detail. like figure 1 As shown, the squeeze container 1 of the present invention has: an open cylindrical neck 10, a shoulder 20 extending substantially horizontally from the base end of the neck 10, a trunk 30 disposed below the shoulder 20, and The bottom portion 40 is provided below the trunk portion 30 .

[0043] The neck 10 has an opening 11 for discharging the contents, such as figure 1 of (a), figure 1 As shown in (b), the neck portion 10 is composed of a cylindrical neck body 12 and a constricted portion (reduced diameter portion) 13 formed below the neck body 12 . On the outer peripheral surface of the neck main body 12, a thread 12a for attaching a cap C that closes the opening 11 is formed. like figure 2 As shown, on the neck 10, in addition to the cap C, a droplet nozzle N capable of dripping the contents drop by drop, and a check valve V for preventing substan...

Abstract

The present invention provides a squeeze container in which it is possible to prevent content from remaining, even without greatly compressing and deforming the vicinity of a shoulder part. The present invention is a squeeze container (1) that discharges content by compressing a body part (30) from outside from the front / rear. The planar-view shape of the body part (30) is polygonal or oval that is shaped so as to be tapered in the left / right direction. The body part (30) includes: a pair of front and rear pressing parts (31) arranged so as to oppose one another such that, by being compressedfrom the front / rear so as to contact one another, the polygonal or oval shape is flattened in the left / right direction; and a pair of left and right tapered parts (32) connecting the pressing parts. Between the pressing parts (31) of the body part (30) and a shoulder part (20), a pair of front and rear V-shaped grooves (50) recessed toward the central axis of the body part (30) is formed so as tooppose one another, an upper bending line (51) extending substantially horizontally serving as the bottom of the grooves.

Description

technical field [0001] The present invention relates to squeeze containers that discharge their contents by compression. Background technique [0002] A general squeeze container usually discharges the contents by compressing the trunk, but only compressing the trunk causes a problem that a large amount of contents remains at the corner formed between the shoulder and the trunk. [0003] In order to discharge the contents of the corner portion, it is necessary to compress and deform the vicinity of the shoulder portion greatly, specifically, it is necessary to fold the inner surface of the shoulder portion and the inner surface of the trunk portion into contact, or to crush the shoulder portion. However, the shoulders are often formed thick, and a large force is required to compress and deform the vicinity of the shoulders. [0004] Therefore, in Patent Document 1, creases are formed in advance near the shoulder so that the vicinity of the shoulder can be compressed and def...
