Hermetic Liquid Container With Flared Cap And Multi-Sided Seal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing containers fail to provide a reliable hermetic seal and easy opening mechanism for liquid containers, particularly for dental adhesives or materials, which are sensitive to atmospheric exposure and light.
Innovation Solution
A container design featuring a base and cap with multi-sided interengaging upper regions, where the cap can be rotated axially to create a hermetic seal and be easily released, utilizing flared faces and sealing rings to protect the contents while allowing manual operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional container design is used, then the structure is simple, but the hermetic seal reliability is insufficient and the opening mechanism is difficult
Solution Approach 1:
The cap is nested within the base in a telescopic arrangement, with the cap's outer peripheral surface fitting into the base's inner peripheral surface. This nested structure allows the sealing surfaces to be in direct contact when the cap is in the retracted position, ensuring reliable hermetic sealing while maintaining a compact overall form.
Solution Approach 2:
The container employs dynamic movement of the cap along the axial direction between retracted and extended positions. When the cap is rotated, it dynamically transitions from the retracted sealed position to the extended opening position, enabling easy opening and closing operations while maintaining seal integrity during storage and transport.
2Ease of operation
If the cap is easily rotatable, then the ease of operation is improved, but the risk of accidental opening increases
Solution Approach 1:
The cap and base feature curved guide surfaces with complementary geometries. The outer peripheral surface of the cap and the inner peripheral surface of the base have curved profiles that guide the cap's axial movement and rotational motion, ensuring smooth operation while the sealing surfaces maintain contact during the opening sequence.
Solution Approach 2:
Before the cap can be fully opened by rotation, it must first be preliminarily moved axially to break the hermetic seal. This preliminary axial movement separates the sealing surfaces, preventing accidental opening while still allowing easy intentional opening through the two-step motion sequence.
3Stability of the object's composition
If the container is protected from light and atmosphere, then the material stability is improved, but the device complexity increases
Solution Approach 1:
The container employs flexible sealing rings made of elastomeric material that can deform to conform to the sealing surfaces. These thin film-like sealing elements create effective hermetic barriers against light and atmosphere penetration while adding minimal structural complexity to the overall container design.
Solution Approach 2:
The container utilizes composite construction with the base and cap made from different materials optimized for their specific functions, combined with elastomeric sealing rings. This composite approach provides effective protection against environmental factors while maintaining a relatively simple overall structure through the use of specialized sealing components.

AI summary
A container (10) has a base (12) on a cap (14). The container (10) has a chamber (38) for liquid. The base (12) on the cap (14) are arranged to be interengaged so as to seal hermetically the chamber (38). The base (12) and the cap (14) have multi-sided portions which interengaged to form the hermetic seal. The cap (14) has outwardly flared sides so that as the cap (14) is rotated relative to the base (12) the cap is caused to move out of the base and the hermetic seal is broken so that the contents of the chamber (38) may be accessed.
