Adhesive Tape

Personal protective equipment [PPE] covers a variety of equipment such as,
waterproof socks, wetsuits, masks, body suits, PPE kit, eye protection glasses; all of which are not perfectly sealed at their borders or ends where they meet with skin of a user or where they meet with other PPE.
Unsealed borders of PPE can cause trench foot, wet body, lower body temperature, bacterial /viral /chemical contamination from outer environment.

Such equipment need perfect sealing at borders near neck, face, wrist, waist, ankles, and the like body parts; so that there is no ingress /egress of air /water.
Aiming to result in an air-tight and water-tight space between skin and inside of PPE. Such a closure provides the most effective protection.

First Initial POC:
There is provided an four-sided adhesive tape, for fluid-tight sealing and for firm grip.

Multiple Application:

This is a schematic representation of how four sided adhesive tape
can be applied on Water proof socks and Face mask.
Similarly it can be used for other applications e.g., PPE borders, Dry suits, Wet suits.

Material properties
Out of Four sided adhesive tape, Different combination is possible
Two plastic grade/ industrial grade adhesive sides and two medical grade adhesive sides.
Four sides can be a combination of medical and plastic grade adhesive tape
All four adhesive sides can be plastic grade/industrial grade.

Differentiation of proposed solution
If single sided adhesive strip is overlapped over borders of PPE, raincoat, water socks, water suits, etc.; this single sided adhesive tape has weak grip over PPE and skin or between PPE and PPE because of its single side of attachment and tape can be either made for skin or for PPE material.

A double-sided adhesive tape is plagued with some disadvantages;
Firstly, both surface or one surface out of these two cannot move;
Secondly, gripping over surface is weak.
Thirdly, these tapes cannot stick two surfaces in a perpendicular effective manner, Fourthly, since PPE borders are directly exposed to outer environment – air and water leakage is highly possible.

Novelty
Four-sided adhesive tape can hold an object or PPE borders in a perpendicular manner and or in a horizontal manner.
Four-sided adhesive tape can, overlap object in a secure manner so that no air or water leakage is possible.
PPE are become more safe, secure, and comfortable, with firm grip over object

Feasibility
Challenges: Invented Four sided adhesive tape, is a combination of medical grade and plastic/ industrial grade adhesive tape.
How to Overcome: This combination of tape can be made manually or with the help of Automation.
