Dispenser Container Shiftable Outlet Pre-ventilation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispenser containers face issues with dirt and harmful particles penetrating through pressure compensation openings, potentially damaging the container, as ventilation or pressure compensation is only possible when fluid is withdrawn, leaving the container vulnerable before use.
Innovation Solution
A dispenser container design featuring a shiftable first outlet region relative to a second outlet region, allowing for pre-ventilation through a pressure compensation opening, which is sealed by a complementary projection before shifting, ensuring pressure compensation is possible before fluid withdrawal, and a pump device can be securely fitted with a holding mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pressure compensation opening is provided in the outer container for pressure compensation during fluid withdrawal, then pressure compensation is enabled, but dirt particles and harmful particles can penetrate into the dispenser container through the opening
Solution Approach 1:
The patent applies preliminary action by providing a vent channel that allows pressure compensation to occur before the outlet valve opens. The vent channel is positioned to enable air intake during filling and pressure equalization during dispensing, preventing negative pressure formation that would otherwise cause liquid to be drawn through the outlet valve. This preliminary pressure compensation action prevents harmful liquid ingress while maintaining the necessary pressure balance.
Solution Approach 2:
The patent uses an intermediary approach by introducing a vent channel as a separate pathway for pressure compensation. This vent channel acts as an intermediary structure that allows air to pass through the container wall independently of the outlet valve, thereby enabling pressure equalization without requiring the outlet valve to open. This separates the pressure compensation function from the liquid discharge function, preventing particle ingress.
2Object-affected harmful factors
If the outlet region is made shiftable to enable pre-ventilation and pump device attachment, then sealing and particle prevention are improved, but the device structure becomes more complex
Solution Approach 1:
The patent applies dynamics by making the outlet region shiftable relative to the container wall. The outlet region can move between a first position (for normal operation) and a second position (for pump attachment and pre-ventilation). This dynamic positioning allows the system to adapt its configuration based on operational needs, enabling both sealed operation and maintenance access through a single integrated structure.
Solution Approach 2:
The shiftable outlet region serves multiple functions: it provides a sealed outlet during normal operation, enables pre-ventilation by allowing air intake before pump activation, and facilitates pump device attachment by creating access space. This multi-functionality reduces the need for separate structures for each function, managing complexity through consolidation.
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 design enhances sealing and prevents particle ingress by allowing pressure compensation before fluid use, protecting the container and ensuring effective operation from the outset, while the shiftable outlet regions facilitate easier pump device attachment and operation.
Implementation Method 1
the inner container being deformable
Implementation Method 2
the inner container has, on an outer face, at least one complementary projection for sealing the pressure compensation opening

AI summary
The invention relates to a dispenser container consisting of an outer container and an inner container for receiving a fluid, wherein the outer container and the inner container are formed from blow-moulded plastics, which do not form an integral connection with one another, and wherein a first plastic from which the inner container is formed has a higher elasticity than a second plastic from which the outer container is formed, such that the inner container is deformable, and wherein the outer container has at least one pressure compensation opening for pressure compensation in the region between the outer container and the inner container, wherein the inner container has a first outlet region and the outer container has a second outlet region, wherein the first outlet region can be shifted relative to the second outlet region in an outlet direction.
