Dispensing Head With Integrated Tamper Seal for First-Use Indication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispensing heads for fluids lack a user-friendly tamper-evident seal that is easy to operate and allows for simple recycling.
Innovation Solution
A dispensing head with a tamper-evident seal that is integrated with the housing part, activated by the actuator's first rotation, ensuring the seal is damaged during initial use without requiring additional steps, and remains connected for easy recycling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a tamper-evident seal is provided on the dispensing head, then product security and tamper indication are improved, but device complexity and difficulty of operation increase
Solution Approach 1:
The tamper-evident seal is integrated directly into the housing part of the dispensing head, merging the sealing function with the structural component. This eliminates the need for separate tamper-evident devices and reduces overall device complexity while maintaining reliable tamper indication through the integrated seal's breakable connection to the housing.
Solution Approach 2:
The actuator's first rotation automatically activates the tamper-evident seal by exerting force that damages or acts upon it. This self-service mechanism eliminates the need for separate activation steps or additional user actions, simplifying operation while ensuring the tamper indication function is reliably triggered during initial use.
2Reliability
If a tamper-evident seal is provided on the dispensing head, then product security and tamper indication are improved, but ease of operation deteriorates
Solution Approach 1:
The tamper-evident seal is automatically activated during the actuator's first rotation without requiring additional user steps. The actuator's rotational movement itself exerts force on the seal to damage or act upon it, making the tamper indication process self-service and maintaining ease of operation.
Solution Approach 2:
The tamper-evident seal is designed to be activated in advance during the first rotation of the actuator, before normal dispensing operations begin. This preliminary action ensures the seal is damaged or actuated during a necessary initial step, preventing any additional operational complexity while maintaining ease of use.
3Reliability
If the tamper-evident seal is damaged during initial use, then tamper indication is improved, but recycling difficulty increases
Solution Approach 1:
The tamper-evident seal remains connected to the housing part even after being damaged during initial use. This integrated design ensures that the seal and housing can be recycled together as a single component, eliminating the need to separate damaged seal fragments and simplifying the recycling process while maintaining reliable tamper indication.

AI summary
A dispensing head for a dispenser for dispensing a fluid is proposed, wherein the dispensing head comprises a housing part and an actuator rotatable relative to the housing part for actuating the dispensing head or dispenser, and wherein the dispensing head, in particular the housing part, comprises a tamper-evident seal. According to a first aspect, the actuator and the tamper-evident seal are configured such that the actuator exerts a force on the tamper-evident seal when the actuator is first rotated relative to the housing part from a first rotational position to a second rotational position, in particular in the direction of rotation of the actuator and/or radially outwards, which causes the tamper-evident seal to be damaged and/or to fold down. According to a second aspect, the tamper-evident seal is formed integrally with the housing part.
