Display Ready Container with Nested Sleeve Preassembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Two-piece containers require multiple steps for assembly, leading to inefficiencies and material waste, while existing solutions do not effectively balance cost reduction with maintaining structural strength.
Innovation Solution
A preassembled container design featuring an outer and inner sleeve, where the inner sleeve has tear-away sections and slots aligning with the outer sleeve's fold lines, allowing for easy assembly into a knockdown form that can be efficiently erected into a fully enclosed container with reduced material usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional two-piece containers are assembled from separate top and bottom sections, then the container can be fully enclosed and secured for shipping, but the assembly process requires multiple steps increasing complexity and time
Solution Approach 1:
The patent combines the top and bottom sections into a single integrated container structure where the top flaps are formed as part of the same blank as the bottom flaps. This merging eliminates the need for separate assembly of two pieces, reducing the number of steps while maintaining full enclosure capability.
Solution Approach 2:
The container is pre-configured with all necessary flaps and structural elements formed during the single-blip manufacturing process. The top and bottom sections are preliminarily arranged in their final spatial relationship, requiring only simple erection steps rather than complex multi-step assembly.
2Strength
If more material is used to create traditional two-piece containers, then structural strength is maintained, but material waste increases and costs rise
Solution Approach 1:
The container blank is segmented into functional zones (bottom flaps, side walls, top flaps) that are efficiently arranged to minimize material waste. The segmentation allows optimal use of material while maintaining structural integrity through strategic placement of reinforcement zones where needed.
Solution Approach 2:
The patent optimizes material parameters such as flap dimensions, panel thickness, and fold line positions to achieve the minimum material required for structural strength. By carefully adjusting these parameters, the design reduces material consumption while maintaining adequate strength for shipping and display applications.
3Adaptability or versatility
If traditional two-piece containers are used for display purposes, then the bottom section can be opened for retail display, but cutting or tearing of the container is required
Solution Approach 1:
The container incorporates dynamic elements such as removable top flaps or panels that can be easily detached or opened without damaging the container structure. This allows the container to adapt from a fully enclosed shipping state to an open display state through simple user actions rather than destructive cutting or tearing.
4Ease of manufacture
If separate top and bottom sections are manufactured, then each section can be optimized independently, but the number of manufacturing steps and assembly operations increases
Solution Approach 1:
The manufacturing process merges the production of top and bottom sections into a single blank formation and folding operation. This eliminates separate manufacturing steps for each section while still allowing optimization of different zones within the unified blank design.

AI summary
A container preassembly which has an inner sleeve in a flat unopened position disposed within an outer sleeve in a flat unopened position, where in the inner sleeve is substantially shorter than the outer sleeve. The two sleeves are adapted for form the top and bottom ends of the final opened container. The inner sleeve is cut so that gaps at the top of the inner sleeve form notches at the corners of the final opened container. The shorter outer sleeve rests on these notches preventing the pieces from shifting during the manufacturing process and to allow the preassembly to be folded into the final container using current machine technology.
