Receiving Container Grip Member and Separation Portion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional packaging boxes are not designed for portability and do not leave traces of opening, making them difficult to pack and carry without visible signs of opening.
Innovation Solution
A receiving container with a hollow tubular body, extending portions, and a grip member that includes attachment portions to prevent opening and facilitate easy carrying, featuring through holes and a separation portion for secure closure and visible trace of opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional packaging box structure is used, then manufacturing without gluing is achieved, but portability and easy carrying are not improved
Solution Approach 1:
The packaging box is divided into modular components: a grip member separate from the box body, extending portions that can be folded, and a separation portion that divides the lid. This segmentation allows each part to serve specific functions (grip member for portability, extending portions for closure) while maintaining manufacturing simplicity through die-cutting and folding alone.
Solution Approach 2:
The grip member extends from the top surface of the box in the vertical dimension, providing a hand-gripping interface without adding horizontal complexity. The extending portions fold vertically to close the opening, transforming the box from an open to closed state through dimensional change rather than lateral movement.
2Ease of operation
If simple closure structure is used, then easy packing is achieved, but visible trace of opening is not left
Solution Approach 1:
The separation portion is pre-formed with a tear line that guides the opening action. When the box is opened, the lid separates along this predetermined path, automatically leaving a visible trace that indicates the box has been opened. This preliminary preparation ensures reliable opening traces without requiring complex locking mechanisms.
Solution Approach 2:
The separation portion can be designed with visual indicators such as colored strips or contrasting patterns along the tear line. When separated, these visual elements create a noticeable trace that clearly indicates the box has been opened, enhancing the reliability of opening detection through optical contrast rather than mechanical complexity.
3Ease of manufacture
If extending portions are used to close opening, then closure is achieved, but attachment strength is insufficient
Solution Approach 1:
The grip member is merged with both extending portions through adhesive attachment, creating a unified structure where the grip member reinforces the connection between the two extending portions. This combination distributes mechanical stress across multiple attachment points and the grip member itself, significantly strengthening the overall attachment beyond what the extending portions could achieve alone.
Solution Approach 2:
The packaging box combines different materials with complementary properties: the box body and lid are made of paperboard or cardboard, the extending portions are made of the same material, and the grip member is made of a different material (such as plastic or reinforced paper) with higher strength and grip characteristics. This composite construction leverages the advantages of each material to achieve both ease of manufacture and high attachment strength.

AI summary
A receiving container includes a container body and a grip member. The container body includes: a body portion in a hollow tubular shape; a bottom portion configured to close one end side opening portion of the body portion; and a ceiling portion configured to close another end side opening portion of the body portion. One of a first extending portion and a second extending portion of the ceiling portion has a separation portion configured to separate a tip portion. The grip member includes: attachment portions, and a grip portion grippable by hand. The attachment portions are configured to prevent the first extending portion and the second extending portion from opening from the other end side opening portion. The attachment portions are attached to a tip side of the separation portion in either of the first or second extending portion provided with the separation portion.
