Peelable Flap Container Lid with Adhesive Reclosure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional containers for storing products often require sharp objects to open and lack a secure mechanism for reclosing, posing risks to consumers and risking damage to contents, while also being aesthetically unpleasing when partially used.
Innovation Solution
A container design featuring a base member with a flexible laminate that includes a peelable flap portion and pressure-sensitive adhesive, allowing for easy access and secure reclosure, with a tamper evident feature to ensure product integrity and user safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional containers use sharp objects to open, then access to product is achieved, but consumer safety is compromised and container structure is damaged
Solution Approach 1:
The container lid is segmented into a removable portion that can be easily detached without sharp objects. The lid includes a window portion and a removable portion that can be pulled off to provide access to the container interior, eliminating the need for knives or other sharp tools.
Solution Approach 2:
A pull tab or access mechanism serves as an intermediary element that facilitates safe opening. The removable lid portion acts as a mediator between the consumer and the container contents, allowing access without direct contact with sharp edges or requiring external sharp objects.
2Ease of operation
If conventional containers lack reclosing mechanism, then opening is simple, but product security and aesthetics are compromised
Solution Approach 1:
The container lid is designed to be removable and replaceable. After opening by removing the lid portion, the same lid can be recovered and reattached to reclose the container, maintaining product security. The lid includes adhesive or snap-fit mechanisms that enable reliable reclosing.
Solution Approach 2:
The lid transitions from a fixed state to a removable state and back again. The container allows dynamic opening and reclosing through the removable lid portion, which can be detached for access and reattached for storage, providing flexibility while maintaining security.
3Ease of operation
If conventional containers require lidding removal, then product access is achieved, but container aesthetics and structure are damaged
Solution Approach 1:
The lid is segmented into a window portion that remains attached and a removable portion that can be detached. This segmentation allows the main lid structure with its aesthetic design to remain intact on the container, while only the necessary access portion is removed.
Solution Approach 2:
Only the necessary portion of the lid (the removable portion) is taken out for access, rather than removing the entire lid. This extraction approach maintains the overall aesthetic appearance of the container while providing sufficient access to contents.
4Reliability
If conventional containers use opaque materials, then product protection is achieved, but consumer visibility is reduced
Solution Approach 1:
The lid incorporates a window portion with different optical properties than the rest of the lid. The window area is made transparent or translucent to allow consumers to view the contents, while the remainder of the lid maintains its protective opaque quality.
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 container allows consumers to easily open and reseal products, maintaining product security and aesthetics, reducing the risk of injury and content damage, while enabling transparent viewing of contents.
Implementation Method 1
At least one of the first or second reclose surfaces may include pressure-sensitive adhesive to allow the peelable flap portion to be re-sealed to a remainder of the flexible laminate
Implementation Method 2
one of an outer surface or an inner surface of the lid of the base member may be coated with low density polyethylene (LDPE), and the flexible laminate may be heat sealed to a respective one of the outer surface or the inner surface

AI summary
Containers are described that allow a consumer to see inside the container and to more easily access the products. One form of the container includes a base member with a lid defining a window. A flexible laminate with a peelable flap portion is attached to the lid to provide access to the products inside. The flexible laminate includes a first film layer laminated to a second film layer. The first film layer includes a first cut line defining a peelable flap portion and the second film layer includes a second cut line offset from the first cut line that defines an opening into the container. First and second reclose surfaces defined between the cut lines on the corresponding film layers include pressure-sensitive adhesive to allow the container to be re-sealed via movement of the peelable flap portion back into engagement with the flexible laminate remaining with the container.
