Benefits of technology

[0012] A primary object of the present invention is to provide a vinyl nitrile co-polymer powder free exam glove, which is good in barrier protection, strength, durability, elasticity, puncture resistance, and chemical resistance, with a solid cost saving.
[0013] Another object of the present invention is to provide a vinyl nitrile co-polymer powder free exam glove, which is not irritating to the human skin.
[0014] Another object of the present invention is to provide a vinyl nitrile co-polymer powder free exam glove, which is inherited all advantageous characteristics of the nitrile gloves but affordable like a conventional vinyl glove.
[0015] Another object of the present invention is to provide a vinyl nitrile co-polymer powder free exam glove, which is comfortable like natural latex gloves.
[0016] Another object of the present invention is to provide a vinyl nitrile co-polymer powder free exam glove, wherein no donning powder would be required to solve the gloves sticking problem.

Problems solved by technology

Unfortunately, the nature proteins of latex glove would cause skin irritations to some users.
The gloves directed contact with the human skin would result to efflorescence and afflicted itching.
There are substantial complaints around the world about the allergic reactions caused by the latex medical gloves.
Even worse, not all latex gloves are created equal, there are significant differences between manufacturers and product lines in the amount of free latex protein that can be liberated from the glove and the number and types of chemicals used in glove production.
A user would have been hassle to choose a glove from a variety of brands.
As a result, the vinyl gloves have been overwhelmed in the market to replace conventional latex gloves.
However, the vinyl gloves have a poor performance in leakage rate with respect to the latex gloves.
That is to say, some of the nitrile gloves are comfortable and fit well, whereas some are stiff and not flexible.
However, disposable glove is a kind of heavily consuming products.
Users would always be in a dilemma between the costs versus quality.

Embodiment Construction

[0028] Referring to FIG. 1, a manufacturing method for preparing a co-polymer glove according to a preferred embodiment of the present invention is illustrated. The glove of the present invention is to provide a patient examination glove, which is disposable device intended for medical purpose that is worn on the hand of healthcare and similar personnel to prevent contamination between healthcare personnel and the patient's body, fluids, waste or environment.

[0029] Accordingly, the present invention provides a glove comprising a thin elastomeric film, the film comprises a co-polymer which is selected from a group consisting of polyvinyl chloride, oil-based liquid nitrile rubber (LNBR), pentanediol diisobutyrate (TXIB), di-isononyl phthalate and calcium zinc stabilizer.

[0030] In other words, the present invention provides a disposable glove which is prepared of polyvinyl co-polymer thus inheriting advantageous characteristics of nitrile gloves but in solid cost-saving like vinyl gl...

Abstract

The present invention discloses a glove as well as the manufacturing method for preparing thereof, the glove comprises a thin elastomeric film, the film comprising a co-polymer which is selected from a group consisting of polyvinyl chloride, oil-based liquid nitrile rubber (LNBR), pentanediol diisobutyrate (TXIB), di-isononyl phthalate and calcium zinc stabilizer. The glove prepared in such method inherited the characteristics of nitrile gloves but with a solid cost saving.

Description

BACKGROUND OF THE PRESENT INVENTION [0001] 1. Field of Invention [0002] This invention relates to disposable gloves, and more particularly, relates to disposable gloves used by the healthcare or similar personnel, wherein the disposable gloves are made of vinyl and nitrile copolymer so as to prevent the skin irritation and simultaneously achieve a solid cost saving. [0003] 2. Description of Related Arts [0004] Commonly, a patient examination glove is a disposable device intended for medical purpose that is worn on the hand of healthcare and similar personnel to prevent contamination between healthcare personnel and the patient's body, fluids, waste or environment. [0005] As a result, such gloves are supposed to provide excellent barrier protection and touching comfort. First of all, gloves should offer barrier protection both for the health care worker and the patient to guard against contact with blood, other body fluids, and micro-organisms. In short, people working in a high-risk...
