Paperboard Container with Tapered Handholds and Partition Shield
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional foldable cartons used for shipping flowable or pourable substances often leak through carry handles, leading to wasted capacity and the need for tamper-resistant, leak-resistant containers that are easily portable.
Innovation Solution
A paperboard container design featuring finger access openings with tapered punch-out panels that fold inwardly to form handhold openings, a tear-out panel for a dispensing opening below the handhold openings, and angled flap panels that create a shield to prevent leakage, along with small tabs to secure the container's corners and prevent leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional foldable cartons are equipped with carry handles for easy grasping, then ease of operation is improved, but leakage of flowable substance through the handles occurs
Solution Approach 1:
A partition panel is introduced as an intermediary element between the container contents and the handhold openings. This partition panel extends downwardly from the top wall flaps to isolate the flowable contents from the handhold openings, preventing direct contact and potential leakage while maintaining the ease of grasping function.
2Quantity of substance
If flowable substance is packed to the top of the container, then capacity utilization is improved, but the substance can spill out through the carry handles
Solution Approach 1:
The partition panel serves as a protective intermediary that allows the container to be filled to the top with flowable substance without risk of spilling through the handhold openings. The partition creates a physical barrier that maintains both full capacity utilization and tamper resistance.
3Ease of operation
If finger access openings are created in end walls for handholding, then ease of operation is improved, but structural integrity may be compromised
Solution Approach 1:
The top wall flaps are folded inwardly beforehand to form a ceiling for the handhold openings before the container is filled and used. This preliminary action strengthens the structural integrity of the end walls by creating a supportive ceiling structure that reinforces the areas around the finger access openings.

AI summary
The present invention is directed to a paperboard container having generally finger access or handhold openings forming carry handles in the end walls. The handhold openings are defined by two adjacent tapered punch-out panels aligned end-to-end and hinged at their outer ends to a respective end wall. When two adjacent tapered punch-out panels punched out they fold oppositely to one another and inwardly into the container in laterally spaced relation to one another on opposite sides of the respective openings. A tear-out panel in one end wall adjoins the associated hand hold openings and when removed forms a dispensing or pourable opening immediately below the associated hand hold openings.
