Paper Container Lid With Arc Creases And Overlapping Flaps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing paper containers with lid functions have complex structures that make assembly difficult, particularly for restaurant staff who need to quickly assemble and use them.
Innovation Solution
The paper container design includes a bottom section, a body section, right and left flaps that overlap to form a lid, a collar section, and an insertion flap. The flaps are designed with arc-shaped creases that allow for the selection of tap width, enhancing convenience and assembly ease.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If multiple flaps are provided side by side on the upper edge of the body section to form a lid, then the container can be easily disposed, but the structure becomes complicated and assembly becomes difficult
Solution Approach 1:
The lid is divided into multiple flaps (right flap, left flap, and insertion flap) that are segmented and arranged side by side on the upper edge of the body section. Each flap can be independently folded and positioned, allowing the lid to cover the opening effectively while maintaining a relatively simple overall structure that is easy to manufacture and dispose.
2Reliability
If the flaps are designed to overlap each other to cover the opening, then the lid function is achieved, but the assembly process becomes more complex
Solution Approach 1:
The flaps are pre-formed with specific geometric shapes and crease lines during manufacturing. The right flap and left flap are designed to overlap each other in a predetermined manner, and the insertion flap is pre-positioned to be inserted into a slit. This preliminary configuration ensures that when the container is assembled, the lid function is automatically achieved without requiring complex assembly steps.
3Adaptability or versatility
If arc-shaped creases are provided between the body section and flaps, then tap width can be selected for enhanced convenience, but the structure becomes more complex
Solution Approach 1:
Arc-shaped creases are provided between the body section and the flaps, allowing the tap width to be dynamically adjusted. The creases enable the flaps to be folded at different angles, creating variable tap widths that can be selected based on user preference or specific usage requirements. This dynamic feature enhances versatility while the creases are integrated into the existing flap structure, minimizing additional complexity.

AI summary
Provided is a paper container which has a lid function and a simple configuration, and which is easy to assemble and highly convenient. The paper container comprises: a bottom section 1; a body section 2; a right flap 11 and a left flap 12 which are formed by being folded inward along a crease 30; a collar section 13 which is formed folded outward along a crease 21 at one end of the right and left flaps 11, 12; and an insertion flap 14 which is formed by being folded inward along a crease 22 at the other end of the right and left flaps 11 and 12. The right and left flaps 11 and 12 overlap each other and cover an opening 3 formed by the body section 2. The right and left flaps 11, 12 have a slit 26 on the insertion flap side. The insertion flap 14 is inserted into the slit 26 and maintains the state of overlap between the right and left flaps 11, 12. Between the body section 2 and the right and left flaps 11, 12, there is also a first arc-shaped crease 31 on the right and left flaps side and a second arc-shaped crease 32 on the body section side.
