Paper Container with Continuous Wall for Reliable Cassette Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional containers with dispensers face issues such as blocked loading spaces, difficulty in loading complex-shaped articles, and poor reproducibility when loading consumables into cartridges, especially in vending machines and automatic systems, due to inadequate control over the posture of falling items and potential deformation under external shocks.
Innovation Solution
A container design featuring a single lid structure with folding surfaces that allow contents to fall parallel along a continuous wall surface, ensuring controlled loading and maintaining the shape of items, even when dropped, by folding back to form a single wall surface and using a grip to facilitate easy opening and closing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional containers with dispensers are used, then opening and dispensing articles becomes easier, but the loading space becomes blocked and loading complex-shaped articles becomes difficult
Solution Approach 1:
The container is divided into a main body portion and a separate lid portion that can be easily detached. The lid includes a grip portion for easy holding and opening, while the main body provides the dispensing function. This segmentation allows the lid to be removed without blocking the loading space, solving both the ease of operation and loading space blockage issues.
2Productivity
If articles are allowed to fall freely into the container, then loading speed increases, but the posture control and shape maintenance of items deteriorates
Solution Approach 1:
The container is designed with a bottom opening that allows articles to be preliminarily positioned in the correct posture before being loaded. The continuous wall surface structure guides the articles into the proper orientation as they fall, ensuring that even at high loading speeds, the posture and shape of the items are maintained without requiring complex control mechanisms.
3Ease of operation
If multiple folding surfaces are used in the lid structure, then the lid can engage and disengage easily, but the structure becomes complex and reproduction of loading becomes poor
Solution Approach 1:
The lid is designed with a simple single folding surface that connects the grip portion to the closing portion. This extracted simplified structure eliminates the complexity of multiple folding surfaces while maintaining easy engagement and disengagement functionality. The single folding surface reduces structural complexity and improves the reproducibility of the loading 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
Enables reliable and efficient loading of articles onto cassettes or cartridges with improved reproducibility, maintaining item shape and preventing deformation, suitable for vending machines and consumable refills.
Implementation Method 1
at least a first folding surface that makes a mountain fold on the first container-constituting surface
Implementation Method 2
a side surface of any one of the contents contacts the continued wall surface formed by the wall surface constituted of the first container-constituting surface and the first folding surface along it

AI summary
A container that is capable of loading articles onto a cassette for containing articles and the like with high reproducibility and is suitably applicable to a paper-made refill, is provided with, as shown in FIG. 1, if two constituting surfaces of container-constituting surfaces, which stand facing each other across an opening (6) with a predetermined size in one of the container-constituting surfaces, are supposed as first and second container-constituting portions (1 and 2), at least a lid-constituting portion (11) that has a width extending beyond the opening (6) and makes a mountain fold on the container-constituting portion (1), and a lid-closing portion (12) that makes a mountain fold on the lid-constituting portion (11) to engage the container-constituting portion (2). The container is formed so that when opening the opening (6), the lid-closing portion (12) disengages the container-constituting portion (2) and the lid-constituting portion (11) is folded back to a position so that it becomes the same wall surface as that of the container-constituting portion (1). When binding members (43) are taken outside while directing a side of the opening (6) downward, a side surface of each of the articles (30) comes into contact with a continuous wall surface formed of a wall surface constituting the container-constituting portion (1) and a wall surface constituting the lid-constituting portion (11) with it being along the continuous wall surface.
