Propelling Container with Click Feedback and Stopper
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional propelling containers for cosmetic and similar materials face issues with recognizing the content amount dispensed, risk of component damage from incorrect operation, and leakage due to residual pressure and viscosity-dependent flow, especially when laid on their side.
Innovation Solution
A propelling container design featuring an inner cylinder with a screw rod, an inner plate threadedly engaged with the screw rod, an annular sealing member for air-tightness, and a rotator with an elastic body generating a click feeling upon rotation, along with a stopper to prevent incorrect rotation and improve sealing, and a dispenser head with a barrier wall to prevent heaping of the content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a smooth rotator is used for propelling content, then the dial can be easily rotated, but it becomes difficult to recognize the amount of content propelled
Solution Approach 1:
The rotator incorporates an elastic body that generates periodic click sensations during rotation, creating distinct tactile feedback intervals that allow users to recognize the amount of content propelled through the sequence of clicks experienced during the propelling action
Solution Approach 2:
The patent uses tactile feedback (click feeling) analogous to visual color changes, where the elastic body's periodic engagement creates distinguishable sensory intervals that indicate progression and amount of content dispensed
2Ease of operation
If the dial can be rotated freely, then operation is simple, but wrong operation can damage component members
Solution Approach 1:
The stopper is positioned in advance to prevent wrong operation before damage can occur. When the inner plate reaches the lowermost end, the stopper blocks further rotation of the rotator, preventing excessive force from being applied to the propelling mechanism components
Solution Approach 2:
The stopper acts as a protective barrier that cushions against wrong operation by physically blocking the rotator before excessive force can damage the inner plate or other component members
3Reliability
If the cap is attached to seal the container, then leakage is prevented, but residual pressure can still lift and leak content into the gap between cap and head
Solution Approach 1:
The inner plate is designed to reach the lowermost end position where the content is fully discharged before the cap is attached. This preliminary completion of discharge prevents residual pressure from lifting and leaking content into the gap between cap and head
4Device complexity
If a single opening is used for discharge, then the structure is simple, but the content tends to heap when discharged
Solution Approach 1:
The single discharge opening is segmented into multiple opening sections by bridges, allowing content to discharge through multiple smaller channels simultaneously. This segmentation prevents heaping while maintaining overall structural simplicity
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 easy recognition of dispensed content, prevents component damage, ensures air-tight sealing, and reduces leakage, allowing for reliable dispensing regardless of content viscosity, with a decorative effect from the segmented discharge holes.
Implementation Method 1
the rotator is provided with an elastic body repeatedly contacted with and moved away from a projection of the inner cylinder upon rotation of the rotator to generate a click feeling
Implementation Method 2
an annular sealing member arranged in the inner plate for keeping an air tight state between the inner plate and the screw rod
Implementation Method 3
a rotator for rotating the screw rod via a connecting rod to slide the inner plate along an axis of the screw rod with the air tight state being kept so that the content in the content filling space is lifted and discharged from the dispenser opening of the dispenser head
Implementation Method 4
a propelling container for discharging a content in the container from an opening of a dispenser head by sliding an inner plate to press or lift the content

AI summary
A highly air-tight propelling container is provided, in which it is easy to recognize how much the content is extruded, and rotation of the rotator is prevented to avoid that the component are damaged by a wrong operation. A propelling container comprises an inner cylinder 1 having a screw rod 2 rotatably standing on a bottom part of the inner cylinder and an inner space surrounded by a side wall and serving as a content filling space M; a dispenser head 4 detachably attached to a mouth part 1c of the inner cylinder 1 and having at least one discharge hole communicated with the content filling space; an inner plate 5 threadedly engaged with the screw rod 2 and having an annular sliding band 5b elastically contacted with an inner face of the side wall of the inner cylinder 1; an annular sealing member 14 arranged in the inner plate 5 for keeping a space between the inner plate 5 and the screw rod 2 in a air tight state; a rotator 6 for rotating the screw rod 2 via the connecting rod 7 to extrude the content in the content filling space M and to discharge it from the dispenser opening of the dispenser head 4 by sliding the inner plate 5 in a air-tight state along an axis of the screw rod 2; and a lid body 21 detachably engaged with an upper part of the inner cylinder 1 to accommodate the dispenser head 4 therein. The rotator comprises a bottom wall part 6a connected to a lower end of the connecting rod 7, and a circumferential wall part 6b extending from a periphery of the bottom wall part 6a along an outer face of the inner cylinder 1 and surrounding the inner cylinder 1, thereby rotatably held by the inner cylinder 1. The rotator is provided with an elastic body 10 repeatedly contacted with and moved away from a projection of the inner cylinder 1 upon rotation of the rotator to generate a click feeling. A stopper 16 is arranged on a base part 3 of the screw rod 2 and associated with a lower part of the inner plate 5 when the inner plate 5 is positioned at the lowest end of the content filling space M, so that rotation of the rotator 6 is prevented.
