Hinge Lid Pack Ramp Element for Easy Goods Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging for aerosol-generating articles and consumer goods makes it difficult to remove items through the access opening, especially when the container is full, due to the design of hinge lid packs constructed from laminar cardboard blanks.
Innovation Solution
A container design featuring a ramp element extending from one side wall into the box, providing a sloping surface for consumer goods to slide towards an access opening in the top wall, combined with a lid flap connected along a hinge line that can move between closed and open positions, and a microsuction closure structure to secure the lid in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a hinge lid pack is constructed from laminar cardboard blanks with a standard box and lid design, then the packaging structure is simple and easy to manufacture, but it makes it difficult for consumer goods to be removed through the access opening when the container is full
Solution Approach 1:
The container is divided into functional zones: a ramp element zone that guides goods, a storage zone, and an access zone. The ramp element is a separate structural component that segments the interior space to facilitate goods movement toward the opening, resolving the contradiction by adding internal segmentation rather than changing the overall simple box structure.
Solution Approach 2:
The ramp element introduces a sloped dimensional feature within the box interior, creating an inclined plane that guides goods from the bottom toward the opening. This dimensional change transforms the flat bottom surface into a sloped guide, enabling easy removal without complicating the external box structure.
2Strength
If the access opening in the top wall is made smaller to maintain structural integrity, then the box strength is improved, but consumer goods become trapped and difficult to remove
Solution Approach 1:
The ramp element acts as an intermediary mechanism between the goods and the opening. Instead of enlarging the opening, the ramp provides a sloped pathway that guides goods toward the opening, allowing small openings to remain structurally sound while enabling easy goods removal through the ramp's guiding function.
Solution Approach 2:
The design replaces the need for large openings with a mechanical guiding system (the ramp). The ramp's inclined plane mechanism substitutes for direct manual manipulation of goods, using gravity and surface geometry to propel goods toward the opening without requiring large access points.
3Object-affected harmful factors
If the lid flap is made secure with a closure structure to maintain freshness, then protection of goods is improved, but the lid becomes harder to open
Solution Approach 1:
The closure mechanism uses parameter changes in the form of weakness lines that alter the structural integrity of the lid at specific locations. These lines allow the lid to transition from a secure closed state to an easy-to-open state by concentrating stress at predetermined locations, resolving the contradiction between security and ease of opening.
Solution Approach 2:
The weakness lines are pre-formed during manufacturing to anticipate future opening actions. This preliminary structural preparation ensures that when opening is needed, the lid will open easily at the predetermined location without requiring excessive force, while maintaining full security during storage.
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
Facilitates easy removal of consumer goods by guiding them along the ramp element through a smaller access opening, ensuring they are not trapped and maintaining the freshness and protection of the goods by securing the lid when not in use.
Implementation Method 1
the closure structure includes a microsuction structure
Implementation Method 2
providing a sloping surface for consumer goods to slide towards an access opening

AI summary
The method includes establishing a blank with a bottom wall, the blank including a first sidewall and a second sidewall on opposing ends of the bottom wall and a lid panel and a top panel on opposing sides of the bottom wall, first folding the first sidewall and the second sidewall to be perpendicular to the bottom wall such that an end panel of a ramp contacts the bottom wall, the ramp being directly connected to a first edge of the first sidewall, second folding the top panel into a first closed position such that a first top wall of the top panel is parallel to the bottom wall as the first top wall at least partially covers the ramp, and third folding the lid panel into a second closed position such that a second top wall of the lid panel covers the first top wall.
