Blow-Molded Container Layout for Fast Filling and Easy Pouring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plastic containers with a single opening for filling and pouring are inefficient for rapid filling and user-friendly pouring, requiring additional steps or materials that hinder single-type disposal and increase material requirements.
Innovation Solution
Designing containers with separate filling and pouring openings, where the center axes of both openings are parallel and oriented to the extrusion direction, allowing flexible and space-saving production, and incorporating adaptable shoulder geometries for easy closure and user-friendly pouring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single opening is provided for both filling and pouring, then the container structure is simple and material usage is reduced, but the filling speed is limited and pouring is less user-friendly
Solution Approach 1:
The single opening is divided into two separate openings: a filling opening and a pouring opening. The filling opening has a larger cross-section to enable rapid filling, while the pouring opening is smaller and positioned lower for user-friendly pouring. This segmentation resolves the contradiction by allowing both functions to be optimized independently.
Solution Approach 2:
The filling and pouring openings are arranged in different spatial positions and orientations. The center axes of both openings are parallel to each other and to the extrusion direction, creating a space-saving configuration that enables rapid filling without significantly increasing structural complexity.
2Ease of operation
If a closure element is inserted between sealing surfaces before welding, then pouring is enabled, but the production process becomes more complex and additional materials are required
Solution Approach 1:
The pouring opening is pre-formed during the extrusion blow molding process itself, rather than requiring post-production insertion of closure elements. The parallel center axis configuration allows the pouring opening to be created in the same molding step, eliminating additional production steps and maintaining single-type disposal capability.
3Productivity
If both filling and pouring openings are provided with sufficient space, then both functions can be optimized, but the material requirement increases and production becomes more difficult
Solution Approach 1:
The filling and pouring openings are arranged with parallel center axes that are parallel to the extrusion direction, creating a space-efficient configuration. This dimensional arrangement allows both openings to have sufficient cross-sectional area for their respective functions while minimizing the overall material requirement and maintaining production efficiency.
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
Enables rapid filling, user-friendly pouring, reduced material usage, and efficient production with no additional steps, facilitating single-type disposal and improved consumer experience.
Implementation Method 1
plastic suitable for blow molding is plasticized and introduced into a tube head by means of an extruder. In the tube head, the plastic is formed into a tube
Implementation Method 2
The hose is introduced into the blow molding tool, inflated by overpressure of a gas when the tool is closed so that the hose expands and is pressed against an inner wall of a cavity
Implementation Method 3
The container blown out of the hose is cooled by means of the inner wall until the plastic is hardened

AI summary
The invention relates to a container produced from a plastic material, in particular by extrusion blow molding, said container comprising a container body having a first end and a second end substantially opposite the first end and having a jacket; a filling opening having a first and second sealing surface formed on the inner wall of the first end, wherein the first and second sealing surfaces can be connected to one another in a fluid-tight manner; and a container base having a standing surface formed at the second end and a pouring opening formed at the first end. The filling opening has a first center axis, and the pouring opening has a second center axis. The first and the second center axis are substantially parallel to one another.
