Glue Applicator Nozzle Sealing With a Compressible Stand
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing glue applicators face issues with nozzle sealing, leading to glue drying out or clogging, especially in cold glue bottles, and there is a need for improved stands to support these applicators effectively.
Innovation Solution
A squeeze container applicator with a chamber and trigger mechanism, combined with a stand featuring a compressible seal to securely hold the nozzle without a cap, using materials like silicone or TPE to prevent glue drying and clogging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pin is used to mate with the needle to seal the nozzle, then the nozzle can be sealed, but it is difficult to mate the pin to the needle and the sealing reliability is poor
Solution Approach 1:
The patent removes the cap and pin assembly from the system entirely. Instead, the nozzle itself is designed with a compressible seal mechanism that seals when the container is squeezed, eliminating the need for separate sealing components like pins and caps.
Solution Approach 2:
The nozzle incorporates a self-sealing mechanism where the compressible container wall directly seals against the nozzle opening during the dispensing action. The squeezing motion that dispenses the adhesive also automatically seals the nozzle, making the system self-servicing without requiring separate sealing operations.
2Ease of operation
If the nozzle is left unsealed, then the container can be easily accessed, but the glue can dry out or clog
Solution Approach 1:
The seal is activated periodically during the dispensing cycle. When the container is squeezed to dispense adhesive, the wall compresses and seals the nozzle. When the squeezing stops, the wall returns to its original shape and the nozzle remains accessible. This periodic sealing action prevents drying and clogging while maintaining ease of access during dispensing.
3Productivity
If ribs are added to compress the squeeze container, then dispensing efficiency is improved, but device complexity increases
Solution Approach 1:
The container wall serves multiple functions: it holds the adhesive, transmits squeezing force to dispense the adhesive, and seals the nozzle during compression. The ribs are integrated into the container structure itself rather than being separate components, making the container structure perform both containment and actuation functions.
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 drying and clogging by maintaining a sealed nozzle tip, ensuring smooth dispensing of cold glue without the need for a cap, enhancing usability and efficiency.
Implementation Method 1
a compressible seal to seal the tip of the nozzle
Implementation Method 2
the 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
