Squeeze Container V-Groove Shoulder Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional squeeze containers require significant force to deform the shoulder portion to remove contents from the corner between the shoulder and body portions, leading to usability issues and potential problems with attached components like nozzles and check valves.
Innovation Solution
A squeeze container design featuring a polygon or oval body portion with front-and-back pressing portions, left-and-right tapered portions, and V-shaped grooves between the body and shoulder portions, allowing for efficient content discharge without extensive deformation of the shoulder area, along with a check valve and droplet nozzle for controlled dispensing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the shoulder portion is compressed and greatly deformed to discharge contents from the corner, then the remaining contents are reduced, but a large force is required and the neck portion may be deformed causing component failure
Solution Approach 1:
The body portion is divided into a pressing portion and a non-pressing portion (shoulder vicinity). The pressing portion is specifically designed to be compressed back and forth, while the shoulder portion maintains its structural integrity. This segmentation allows contents to be discharged without requiring large forces on the shoulder portion, preventing neck deformation while still reducing remaining contents.
Solution Approach 2:
The pressing portion is given different mechanical properties compared to the shoulder portion. The pressing portion is designed with thickness and structural characteristics that make it suitable for repeated compression, while the shoulder portion maintains its original strength. This local differentiation allows the pressing portion to deform easily under compression while the shoulder and neck portions remain stable.
2Quantity of substance
If the shoulder portion is greatly deformed to reduce remaining contents, then content discharge is improved, but the neck portion may be deformed causing components to come off or leak
Solution Approach 1:
The container is segmented into a pressing portion that undergoes deformation and a shoulder/neck portion that maintains structural stability. The pressing portion is specifically designed to be compressed back and forth, while the shoulder portion with its attached neck and components remains outside the deformation zone, preventing component failure.
Solution Approach 2:
Different parts of the container have different mechanical characteristics. The pressing portion is designed with local quality suitable for compression (thinner, more flexible), while the shoulder and neck portions maintain higher strength and rigidity to protect attached components from deformation and failure.
3Productivity
If the body portion is compressed back and forth to discharge contents, then content dispensing is efficient, but the corner between shoulder and body portion retains a large amount of contents
Solution Approach 1:
The pressing portion is pre-formed with a shape and thickness that enables effective back-and-forth compression. This preliminary design ensures that when compression is applied, the pressing portion deforms in a way that effectively reduces remaining contents in the corner, achieving high discharge efficiency without requiring excessive force on the shoulder portion.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design reduces remaining contents at the corner, minimizes deformation of the neck portion, and prevents excessive discharge, enhancing usability and structural integrity while allowing for easy content dispensing.
Implementation Method 1
a pair of front-and-back V-shaped grooves are provided between each of the pressing portions of the body portion and the shoulder portion so as to face each other while being recessed in a central axis direction of the body portion and having a groove bottom formed by an upper bending line extending substantially horizontally
Implementation Method 2
the neck portion is provided with a check valve for allowing a flow from inside to outside and blocking a flow from outside to inside

AI summary
The present invention provides a squeeze container capable of reducing remaining contents without greatly compressing and deforming the vicinity of a shoulder portion thereof. The present invention relates to a squeeze container (1) for discharging contents by compressing a body portion (30) back and forth from the outside, wherein the body portion (30) has a shape of a polygon or an oval tapered in a left-right direction in plan view, the body portion (30) includes a pair of front-and-back pressing portions (31) that is disposed to face each other so as to flatten the polygonal or the oval in the left-right direction by being compressed back and forth so as to be brought into close contact with each other, and a pair of left-and-right tapered portions (32) connecting the pressing portions (31) to each other, and a pair of front-and-back V-shaped grooves (50) are provided between each of the pressing portions (31) of the body portion (30) and the shoulder portion (20) so as to face each other while being recessed in a central axis direction of the body portion (30) and having a groove bottom formed by an upper bending line (51) extending substantially horizontally.
