Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing containers for liquid products face challenges in simplified disposal due to difficulties in removing and applying inner coverings, which often require special machinery and laborious operations, leading to increased costs and inefficiencies.
Innovation Solution
A method involving a covering layer applied to a pad with suction holes, an adhesive layer, and a foldable bottom for easy attachment to the container's inner surface, allowing for quick and reliable detachment without specialized equipment, using easily sourced materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a covering layer is applied to the inner surface of the container to enable easy removal and reduce waste, then the ease of disposal is improved, but the device complexity increases due to the need for special machinery and laborious operations
Solution Approach 1:
A pad is introduced as an intermediary carrier that temporarily holds the covering layer during application. The pad simplifies the process by providing a manageable substrate that can be easily positioned and pressed against the container inner surface, eliminating the need for complex machinery while ensuring complete coverage.
Solution Approach 2:
The covering layer is pre-applied to the pad before insertion into the container. This preliminary action allows the covering to be prepared in advance under controlled conditions, making the actual application to the container simple and quick, thereby reducing device complexity while maintaining ease of disposal.
2Ease of operation
If a covering layer with grip elements is designed for easy removal, then the ease of operation is improved, but the manufacturing precision requirements increase to ensure proper detachment
Solution Approach 1:
Grip elements are added locally to specific portions of the covering layer, particularly at the edges or selected areas. This localized enhancement provides easy detachment without requiring high precision across the entire covering structure, as the grip elements serve as dedicated access points for removal.
3Manufacturing precision
If special machinery is used to apply the covering layer, then the manufacturing precision is improved, but the loss of substance increases due to material waste from complex processes
Solution Approach 1:
The pad serves as a self-contained carrier that brings the covering layer directly to the container in a ready-to-apply state. This self-service approach eliminates the need for complex application machinery that would generate material waste, while still achieving precise coverage through the simple act of pressing the pad against the container inner surface.
4Ease of operation
If the covering layer is made easily removable with grip elements, then the ease of operation is improved, but the strength of the covering may be compromised
Solution Approach 1:
The covering layer is designed with differentiated properties: the main body maintains sufficient strength through appropriate material selection and thickness, while specific localized portions incorporate grip elements or thinner sections that facilitate easy detachment. This local differentiation allows the covering to be both strong enough for its protective function and easy to remove when needed.

AI summary
A method for providing a container for liquid products and the like, with simplified disposal, consisting in applying a covering layer (1) on a lateral surface of a pad (2), applying a covering bottom (10) to the base (5) of the pad (2), folding the perimetric edge (10a) of the covering bottom (10) onto the covering layer (1), jointly connecting the perimetric edge (10a) to the covering layer (1), inserting the covered pad (2) in a container (3) in order to apply the covering layer (1) with the bottom (10) to the inner surface of the container (3), extracting the pad (2) and folding onto the container (3) the free edge (1d) of the covering layer (1).
