Glue Applicator Stand With Compressible Seal Against Nozzle Clogging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Precision cold glue bottles face difficulties in sealing, leading to glue dryness and clogging due to the challenge of mating the pin with the needle, which is not effectively addressed by existing designs.
Innovation Solution
The proposed solution involves an applicator with a chamber and ribs to compress the squeeze container, and a stand with a compressible seal to securely hold the nozzle tip, preventing dryness and clogging by sealing the nozzle without the need for a cap.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pin and needle sealing mechanism is used in precision cold glue bottles, then the nozzle can be sealed when not in use, but it is difficult to mate the pin to the needle to seal the needle effectively
Solution Approach 1:
The patent removes the complex pin-and-needle sealing mechanism from the glue bottle design. Instead, it uses a simple cap that snaps onto the bottle opening, eliminating the difficult mating operation while maintaining sealing functionality. The sealing function is extracted from the nozzle area and moved to the bottle opening where a simple cap provides effective sealing.
Solution Approach 2:
Rather than trying to seal the nozzle tip with a pin inserted through the cap (as in conventional designs), this patent inverts the approach by sealing the bottle opening with a cap, which prevents glue from contacting the exterior and drying out. The sealing location is inverted from the nozzle tip to the bottle opening.
2Ease of operation
If the nozzle is left unsealed, then the cap can be easily removed and reattached, but the glue can dry out or clog the nozzle
Solution Approach 1:
The cap is designed to be applied preliminarily to seal the bottle opening before any potential exposure to air. This preliminary sealing action prevents glue from reaching the exterior surfaces where it could dry out, while still allowing easy removal and reattachment of the cap when needed.
3Reliability
If frequent cap replacement is needed to maintain nozzle functionality, then the nozzle can remain accessible, but time is lost and user convenience is reduced
Solution Approach 1:
The cap provides preliminary and continuous protection of the glue interior, eliminating the need for repeated cap replacements. Once the cap is initially placed on the bottle, it maintains sealing throughout storage and non-use periods, requiring minimal user intervention and time investment.
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
The solution effectively prevents glue dryness and clogging by ensuring the nozzle remains sealed, allowing for continuous use and reducing the need for frequent cap replacement, while enabling easy dispensing of substances like cold glue or icing.
Implementation Method 1
a bottom that includes a compressible seal to seal the tip
Implementation Method 2
an applicator that includes... a plurality of ribs that are spaced about a perimeter of the interior surface, protrude into the chamber, and are configured to compress the squeeze container

AI summary
Stands for glue and other applicators are described. The stand may include a seal that allows a user to place the applicator nozzle in the hollow interior of the receptacle without the cap without fear of the liquid in the nozzle clogging or drying out.
