Point of Sale Envelope with One-Handed Peelable Flap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing point of sale envelopes lack efficient designs for easily opening and viewing contents, such as change and receipts, and often require two hands, which can complicate customer use.
Innovation Solution
The development of point of sale envelopes formed through a process involving substrate cutting, creasing, perforating, scoring, and gluing, with specific fold lines and die-cutting to create a pocket that can be easily opened with one hand, allowing contents to be viewed through a cut-out portion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional envelope designs are used, then the envelope structure is simple and easy to manufacture, but the envelope requires two hands to open and makes it difficult to view contents
Solution Approach 1:
The envelope is divided into distinct functional sections: a pocket for holding contents, a flap for closing, and a window portion for viewing. This segmentation allows each part to serve its specific function independently, enabling one-handed operation while maintaining structural integrity
Solution Approach 2:
A window portion is added to the envelope face, creating a new dimensional feature that allows visual access to contents without physical opening. This dimensional addition transforms the envelope from a purely functional container to one with informational transparency
2Reliability
If the envelope includes a pocket and flap design, then contents can be securely held, but the envelope requires tearing or complex opening actions
Solution Approach 1:
The envelope is pre-formed with a pocket and flap structure during manufacturing, with the flap designed to peel back along predetermined tear lines. This preliminary structuring allows the user to simply peel the flap open without complex manipulation, while the pocket remains intact to retain contents
Solution Approach 2:
The opening function is extracted from the main envelope body through a separate peelable flap design. The flap can be removed or peeled back independently, allowing access to contents without disturbing the pocket structure that holds the change and receipt
3Ease of operation
If the envelope is designed for secure closure, then contents remain protected, but the envelope cannot be easily opened with one hand
Solution Approach 1:
The flap is designed with asymmetric tear lines and adhesive application patterns that allow easy peeling in one direction while maintaining strong closure when sealed. The structure transitions from a static sealed state to a dynamic easy-open state through simple peeling motion
Solution Approach 2:
Adhesive material serves as an intermediary between the flap and envelope body, providing secure closure when bonded but allowing easy separation when the adhesive bond is broken along predetermined tear lines. The adhesive enables both strong closure and controlled opening

AI summary
Point of sale envelopes and methods of producing the same are disclosed herein. An example method includes moving a substrate in a direction. The substrate includes a first side opposite a second side. The method includes applying adhesive to the second side of a first portion and a second portion of a first panel of the substrate. The first portion is spaced apart from the second portion. The method includes folding the first panel about a first fold line to couple the first panel to a second panel of the substrate and forming an opening to a pocket in the first panel. The pocket is defined by the second panel and a third portion of the first panel. The third portion is positioned between the first and second portions.
