Closure Cap With Pivoting Drinking Nozzle For Medical Fluid Containers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing closure systems for medical liquid containers, particularly those with piercable membranes, are difficult to handle, especially for debilitated individuals, as they cannot be easily closed or provide adequate air supply, leading to spillage and handling challenges.
Innovation Solution
A closure cap with a pivoting drinking nozzle that pierces the membrane to connect with the container's interior for both drinking and air supply, featuring a tubular body or additional penetrating spike for simplified handling and secure sealing, integrated into a single-stage production process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a piercable membrane is used to seal the container mouth, then the container can be sealed securely, but it becomes difficult for debilitated individuals to pierce and drink from
Solution Approach 1:
The closure cap is divided into separate functional components: a piercing element (needle or spike) integrated into the cap, and a drinking spout that can be positioned independently. This segmentation allows the piercing function to be simplified while maintaining sealing integrity through the separate action of the drinking spout.
2Ease of operation
If a straw is used to pierce the sealing foil, then the container can be opened for drinking, but the container cannot be closed again creating spillage risk
Solution Approach 1:
The closure cap is pre-designed with an integrated piercing element that automatically pierces the sealing foil when the cap is placed on the container. This preliminary action eliminates the need for separate straw piercing and enables subsequent secure closure, as the piercing is already completed before the drinking process begins.
Solution Approach 2:
The closure cap acts as an intermediary device that combines both the piercing function and the closure function. The piercing element (needle or spike) integrated into the cap serves as the mediator that pierces the sealing foil, while the cap itself provides the closure mechanism, eliminating the need for separate straw and closure components.
3Reliability
If air is not supplied to the container during drinking, then the sealing remains intact, but it becomes difficult for debilitated individuals to drink
Solution Approach 1:
The closure cap incorporates separate functional zones: a piercing element for breaching the seal, and a drinking spout with air supply capability. This segmentation allows air to be supplied through dedicated channels or openings in the cap structure, facilitating easier drinking for debilitated individuals while maintaining sealing integrity through the separated functions.
4Ease of operation
If a complex piercing device is integrated into the closure cap, then the container can be easily opened, but production becomes more complicated and costly
Solution Approach 1:
The piercing element (needle or spike) is integrally formed with the closure cap body as a single molded piece. This merging of functions into a single component eliminates the need for separate piercing devices and simplifies production to a single-stage injection molding process, reducing both complexity and cost while maintaining ease of opening.
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 closure cap allows easy handling and secure closure of containers, ensuring contents are retained and providing adequate air supply, making it suitable for debilitated individuals, with simplified production and tamper-evidencing features.
Implementation Method 1
means for piercing the membrane sealing the mouth section of the container, which co-operate with the drinking nozzle in such a way that the membrane is pierced when the drinking nozzle is pivoted, thus causing a connection to be made between the opening in the drinking nozzle and the interior of the container
Implementation Method 2
the main closure body also has an opening for supplying the container with air when drinking. The means for piercing the membrane co-operate with the drinking nozzle in such a way that, when the drinking nozzle is pivoted, a connection is made not only between the interior of the container and the opening in the drinking nozzle but also between the interior of the container and the opening for supplying air

AI summary
The invention relates to a closure cap for a container filled with medicinal fluid, which container has an aperture piece which is sealed off by a diaphragm which can be punctured. The closure cap has a cap-shaped closure body (1) and a drinking neck (4) with a drinking opening (4a) which is pivotable between a first position, in which the drinking neck bears against the closure cap, and a second position, in which the drinking neck projects from the closure cap. In addition, the closure cap has means (20, 22) for puncturing the diaphragm which seals off the aperture piece of the container, which means (20, 22) interact with the drinking neck in such a way that, as the drinking neck (4) is pivoted, the diaphragm is punctured such that a connection is produced between the opening (4a) of the drinking neck and the container interior. The closure cap is characterized in that the closure body has, in addition to the opening (4a) of the drinking neck (4), an opening (20a, 24) for ventilating the container during drinking.
