One-Handed Zip Bag Opener

USER

People with hemiplegia or reduced grip strength who want to open and close zipper bags with one hand

WHAT

A self-help device that makes it easy to open and close zip bags with just one hand. Simply hold the main body and slide it along the opening to open or seal the bag, so people with weak grip strength or those who must work one-handed can handle it smoothly. Non-slip rubber is attached to the bottom to hold the bag firmly in place. For example, someone who stores sesame seeds or medication in zip bags can take the contents out using only their own strength, which improves independence in daily life.

This 3D-printed grip with a rubber sheet makes it possible to open and close zipper bags with one hand. Its non-slip design lets you handle the bag steadily whether opening or closing it. We developed the shape and material in consultation with users, so that it is easy to use for people with weak grip strength or paralysis. It supports the joy of doing things on your own without relying on others.

Accessories

No accessories are included. Use it together with a commercially available rubber sheet. The feel of use may differ depending on the size and specifications of the zipper bag.
