Solution Overview

Problem

Existing packaging solutions for beverage containers, particularly those with tapered necks, face challenges in secure fixation and accessibility during machine handling, leading to instability and difficulty in handling.

Innovation Solution

A method involving a packaging unit with an outer packaging that includes defined buckling and bending lines, allowing side walls to be pressed inward for secure orientation and fixation, combined with a horizontal conveyor system and manipulator for efficient insertion and closure, ensuring the upper flap is folded and fixed to create a stable packaging unit.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional packaging without inwardly pressed side walls is used, then the packaging structure is simple and easy to manufacture, but the beverage containers cannot be securely held at the neck and are unstable

Engineering Contradiction:
Improvestability of beverage container fixationVSAvoidcomplexity of packaging structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The side wall is divided into an upper section and a lower section by a defined buckling line. The upper section can be pressed inward independently to create a tapered shape that secures the beverage container neck, while the lower section remains unchanged. This segmentation allows the packaging to gain stabilizing functionality without overly complicating the overall structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The defined buckling lines are pre-formed in the side walls during packaging manufacturing, but the actual inward pressing of the side walls occurs after the beverage containers are inserted into the packaging. This preliminary preparation of buckling lines enables easy and quick side wall deformation without requiring complex equipment during the insertion process.

Inventive Principle:
Principle #10Preliminary action

2Ease of operation

If cuboid-shaped outer packaging is used, then the packaging is easy to manufacture, but it is difficult to access for machine handling when moved in immediate succession

Engineering Contradiction:
Improveaccessibility for machine handlingVSAvoidcomplexity of packaging shape
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The packaging transitions from a static cuboid shape to a dynamic structure where the upper side walls can be pressed inward to create a tapered form. This dynamic shape change allows the packaging to adapt between a stable cuboid form for stacking and a tapered form with protruding necks for easy machine gripping and handling.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention adds a dimensional aspect to the packaging by creating protruding necks that extend beyond the main body of the packaging. This dimensional protrusion provides machine handling elements that can easily grip and manipulate the packaging in sequences, solving the accessibility problem without fundamentally changing the base cuboid structure.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Reliability

If adhesive is applied to multiple flaps before item insertion, then the top flap can be securely folded and fixed, but the manufacturing process becomes more complex and time-consuming

Engineering Contradiction:
Improvesecurity of top flap closureVSAvoidspeed of packaging assembly
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The adhesive is applied to the side walls and top flap in advance, before the beverage containers are inserted into the packaging. This preliminary adhesive application allows the containers to be quickly inserted without interrupting the bonding process, and the top flap can be immediately folded and secured, maintaining high production speed while ensuring reliable closure.

Inventive Principle:
Principle #10Preliminary action

AI summary

A method for producing a packaging unit is disclosed. In this method, an outer packaging (2) is provided. At least one article (12) is inserted into the provided outer packaging (2) from above. Furthermore, an upper flap (21) of the provided outer packaging (2) is folded over, into which the at least one article (12) has been inserted. The upper flap (21) is secured in its folded position, thereby closing the top of the outer packaging (2) and forming a packaging unit (4) together with the at least one inserted article (12).It is provided that at least one side wall (25) of the provided outer packaging (2) comprises at least one defined crease and/or bend line (24), via which at least one defined crease and/or bend line (24) presses the at least one side wall (25) of the provided outer packaging inwards and fixes it in an orientation (26) provided for the packaging unit and pressed inwards.
