Bottom-Loading Dispenser with Movable Support to Prevent Overfilling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispensers for folded web material face challenges in replenishing from the bottom end, leading to difficulties in managing the weight of large stacks and preventing overfilling, which can cause pinching and dispensing issues.
Innovation Solution
A dispenser design with a web material storage section that includes a movable supporting arrangement allowing for easy insertion of new stacks from the bottom, featuring a loading opening and a supporting mechanism that moves away to enable stack introduction, ensuring the stack is compressed and interconnected, and preventing overfilling by requiring a specific distance to be traveled for new material introduction.

Engineering Contradiction Analysis
1Quantity of substance
If a too large amount of folded web material is stored in the dispenser, then the storage capacity is increased, but the material becomes pinched and difficult to dispense
Solution Approach 1:
The supporting arrangement prevents overfilling by requiring that a specific distance be traveled for new material introduction. The support moves from the loading opening toward the stack, and if the stack is too large, the support cannot reach its full travel distance, providing preliminary prevention against overfilling that would cause pinching and dispensing difficulties

AI summary
The present disclosure relates to a dispenser (2) for dispensing a sheet of web material from a stack (82) of folded web material, the dispenser (2) comprising: a web material storage section (16) arranged to hold and support the stack (82) of folded web material, in a generally vertical direction during dispensing of the web material; the web material storage section (16) comprising an upper end portion (18) from which the web material is arranged to be lead for dispensing thereof, a lower end portion (20), opposite to the upper end portion (18) and being arranged to support the stack (82) of folded web material in said generally vertical direction (12), at least when the dispenser is in said dispensing position, said upper end portion (18) and lower end portion (20) being arranged in a fixed spatial relationship. The lower end portion (20) of the web material storage section (16) comprises -a loading opening (62) and -a supporting arrangement (70), arranged to be movable between a support position wherein the supporting arrangement extends at least partially over said loading opening (62) enabling said support of the stack of folded web material, and an insert position, wherein the supporting arrangement (70) is at least partially removed from the loading opening; wherein said supporting arrangement (70) is arranged to be movable from said support position to said insert position by pushing a stack (82) to be introduced in the loading opening towards the supporting arrangement (70) in a direction towards the upper end portion (18) of the web material storage section (16).
