Erectable Food Container Joint Sealing for Moisture and Oil Leakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional erectable-type containers allow moisture and oil from food to seep out through their joints, necessitating a container that prevents leakage while maintaining durability.
Innovation Solution
A food container with a flat bottom and side part sealed by an insoluble sealing material, adhered with adhesive, made of woody material, featuring a cross-section seal and engagement mechanism to prevent moisture and oil leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional erectable-type containers are used, then the container can be kept compact for transportation and inventory management, but moisture and oil from food seep out through the joints of members
Solution Approach 1:
A waterproof adhesive is introduced as an intermediary substance between the wooden members to seal the joints. The adhesive fills the gaps and pores at the joint interfaces, creating a waterproof barrier that prevents moisture and oil from food from seeping through, while maintaining the simplicity of the joint structure
Solution Approach 2:
The container combines woody material with waterproof adhesive to create a composite structure. The wooden members provide the structural framework while the waterproof adhesive forms a sealing layer at the joints, creating a composite material system that兼具 structural integrity and leakage prevention
2Reliability
If conventional erectable-type containers are used, then the container structure is simple and easy to manufacture, but the durability is poor due to moisture infiltration at joints
Solution Approach 1:
The waterproof adhesive serves as a mediator that enhances the durability of the container by sealing the joints against moisture infiltration. While it adds a manufacturing step, the adhesive application is straightforward and does not significantly complicate the overall manufacturing process
Solution Approach 2:
The invention changes the chemical parameter of the joint interface by applying waterproof adhesive, which modifies the permeability and hydrophobicity of the joint region. This parameter change prevents moisture infiltration and thereby improves durability without fundamentally altering the manufacturing process
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 container effectively prevents moisture and oil from seeping out, ensuring excellent durability even when storing food with high moisture or oil content.
Implementation Method 1
a cross section appearing on a periphery of the bottom part is sealed with an insoluble sealing material which prevents moisture infiltration
Implementation Method 2
the side part is adhered to the bottom part by adhesive or the sealing material interposed between the cross section appearing on the periphery of the bottom part

AI summary
An erectable-type container having excellent durability is provided. The container 1 includes a bottom part 11, a side part 12 forming a box-shaped storage 1a with the bottom part 11, and a cross section appearing on a periphery 11a of the bottom part 11 is sealed with an insoluble sealing material which prevents moisture infiltration, and the side part 12 is adhered to the bottom part 11 by adhesive or the sealing material interposed between the cross section appearing on the periphery 11a of the bottom part 11. Further, the bottom part 11 is circular, and the side part is annular. Furthermore, the side part 12 is formed by engaging a belt-shaped body having an engagement protrusion 121 on one end and an engagement recess 122 on another end.
