Solution Overview

Problem

Traditional fixed-amount discharge squeeze containers require complex structures and increased manufacturing costs due to the need for abutment members or cylindrical cover members to restrict squeeze deformation, leading to variations in discharge amount during repeated operations.

Innovation Solution

A plastic-made squeeze-deformable container body with a squeeze operating portion featuring a mountain-like compression face portion and an arc-shaped or U-shaped compression support portion, which restricts deformation to maintain a constant discharge amount by expanding the intersecting angle between inclined face portions, preventing variation during repeated squeeze operations.

Solution Approach 1:

The invention removes the need for separate abutment members or cylindrical cover members by integrating the deformation restriction function directly into the container body's compression support portion. The container body itself forms the restriction structure, eliminating additional components while maintaining discharge consistency.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The invention merges the deformation restriction function with the container body structure by forming the compression support portion as an integral part of the container body. This combines the support function with the existing structure, avoiding separate components and reducing overall complexity.

AI summary

A fixed-amount discharge squeeze container (10) which discharges a specific amount of content liquid from a discharge port by squeeze deformation of a container body (11) includes a squeeze-deformable plastic-made container body (11) and a squeeze operating portion (14) to perform squeeze operation is arranged at a barrel portion (13) of the container body (11). The squeeze operating portion (14) has a cross-sectional shape formed with a compression face portion (16) having a mountain-like section including a pair of inclined face portions (15) arranged along two faces intersecting obtusely and a compression support portion (18) having an arc-shaped section which is jointed integrally with foot parts (19b) of the compression face portion (16) respectively via an edge line portion (17). The compression face portion (16) is restricted so as not to be flipped into a valley-like shape after the inclined face portions (15) deforms until force to expand the distance between the bilateral foot parts (19b) vanishes.
