Applying Material Extruding Container With Segmented Middle Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing applying material extruding containers face issues where the leading portion, made of soft materials, can detach from the rear portion, leading to a loss of airtightness and inefficiency in material application.
Innovation Solution
The container design incorporates a middle member with an annular shape, engaged with both the leading and rear portions, featuring outer and inner peripheral projections that secure the leading portion to the rear portion, ensuring it remains attached and maintaining airtightness, with the leading portion made of soft rubber or thermoplastic elastomer and the rear portion made of hard thermoplastic resin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the leading portion is formed of a soft material to enable elastic recovery and material extrusion, then the applicability and ease of operation are improved, but the leading portion may detach from the rear portion of the container
Solution Approach 1:
The container is divided into three main segments: the leading portion (10), the middle member (30), and the rear portion (20). The middle member acts as a connector between the leading and rear portions, while the leading portion remains soft for material extrusion. This segmentation allows the soft leading portion to maintain its elasticity for easy operation while the rigid middle member ensures reliable attachment to the rear portion.
Solution Approach 2:
The middle member (30) serves as an intermediary component between the soft leading portion (10) and the rigid rear portion (20). It provides a stable connection point for the leading portion while being firmly attached to the rear portion, thereby preventing detachment while allowing the leading portion to maintain its soft, elastic properties for material extrusion.
2Ease of operation
If the leading portion is made soft and elastic for material discharge, then the ease of operation is improved, but the structural strength decreases leading to potential separation
Solution Approach 1:
The container structure is segmented into functional zones: the leading portion (10) is made of soft material for ease of operation and material extrusion, while the middle member (30) and rear portion (20) are made of rigid materials providing structural strength. This segmentation allows each part to have optimized properties for its specific function without compromising overall structural integrity.
Solution Approach 2:
The container employs composite construction with different materials for different parts: the leading portion uses soft elastomeric materials for flexibility and ease of operation, while the middle member and rear portion use rigid thermoplastic resins for structural strength. This composite approach allows the system to simultaneously achieve ease of operation and maintain structural strength.
3Reliability
If the leading portion is detached preventable by engagement structures, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The container is segmented into modular components (leading portion, middle member, rear portion) that can be assembled and disassembled. The engagement structures are integrated into these segments rather than being separate additional components, thereby providing reliable attachment while maintaining relatively simple device architecture.
Solution Approach 2:
The engagement structures are merged with the functional components themselves. The outer peripheral projection is integrated into the leading portion, and the inner peripheral projection is integrated into the middle member. This merging approach provides reliable attachment without adding separate complex fastening mechanisms.

Function Achieved in This Case
This design effectively prevents the leading portion from detaching from the rear portion, ensuring reliable airtightness and efficient material application, with significant prevention of separation when using materials like soft rubber or thermoplastic elastomers.
Implementation Method 1
an outer peripheral surface of a rear end portion in the filling portion is provided with an outer peripheral projection which extends along a peripheral direction
Implementation Method 2
the outer peripheral projection and the inner peripheral projection are engaged with each other at least in an axial direction
Implementation Method 3

AI summary
An applying material extruding container includes a leading portion including a filling portion filled with an applying material and a flat applying portion and a grip tube inserted into the leading portion. The applying material is extruded from a discharge portion on a leading end side of the applying portion by pressing and deforming the filling portion so as to be used. The applying material extruding container includes an annular middle member engaged with the leading portion and the grip tube. An outer peripheral surface of a rear end portion in the filling portion is provided with a collar portion extending along a peripheral direction. An inner peripheral surface of a front end portion in the middle member is provided with an inner peripheral projection which extends along the peripheral direction. The collar portion and the inner peripheral projection are engaged with each other in an axial direction.
