Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 Disposable gloves for processing where it is not desirable for humans to directly touch the object in fields such as food processing, testing and research, medical treatment and drug handling sites, etc., especially for waste disposal gloves characterized by treatment after use It is a thing.

[0002]

[Prior art]

 The material of disposable gloves for one-time use prevents miscellaneous bacteria and dirt that may be attached to human hands from transferring and contaminating the object, and conversely protects the object from danger and dirt. In order to protect it, strength is required, and since it has to be low cost because it is a one-time use, most of them are made of polyethylene film.

Although it is a polyethylene film that can withstand pulling and rubbing, is not damaged by strong alkali and acid, and can withstand the viscosity of heavy oil, it is incinerated or burned at the stage of disposal after being used. The problem is that there is no disposal method other than landfill.

[0004]

[Problems to be solved by the device]

 When exchanging diapers for people who do not remain in the body at the site where disposable gloves are needed, especially in the care site for the elderly and the physically handicapped, it is necessary to remove feces in the case of a cloth diaper and then wash. The polyethylene film gloves used to remove feces must be treated separately.

That is, a caregiver can remove stools of a physically handicapped elderly person while exchanging diapers, and clean and clean a dirty body because the stools do not directly adhere to the hands. Disposable gloves are used.However, in the case of a cloth diaper, it is necessary to remove adhered feces in the toilet by hand before putting it in the washing machine. Is coming.

[0006] Therefore, a storage place for used gloves is required, and it cannot be left for a long time from a hygiene point of view in the summer, and care must be taken to discard it. It was necessary to do something other than the task of doing.

[0007] In addition, when polyethylene is incinerated, black smoke and a foul odor are generated, and landfill in the soil is not a property that can be decomposed with time, which causes a problem for posterity from the viewpoint of environmental protection. .

In consideration of such post-treatment of gloves, Japanese Examined Patent Publication No. 29574/1996 proposes a microbiodegradable thermoplastic resin film fused body, which is also mentioned in the description of the plan. In addition, the physical properties are only "easy disintegration in an environment where microorganisms exist and reduction in bulk", and they are not easily dissolved in water, so a complete solution has not been reached.

[0009]

[Means for Solving the Problems]

 The inventors of the present invention faced various daily problems of care if the gloves as well as the feces could be directly discharged to the flush toilet or sewer in the above-mentioned field of care for the elderly and the physically handicapped. We focused on reducing the burden on existing nurses and home helpers.

Therefore, instead of polyethylene film gloves, a material of polyvinyl alcohol film (hereinafter referred to as PVA film), which is characterized in that 80% to 100% of its own weight is water-solubilized in water at 20 ° C. or less, is used as a material. We found that many caregivers did not have to worry about disposing of gloves dirty with feces when exchanging diapers, and were able to concentrate on other detailed work. did.

However, when such a filth-disposal glove is flushed into a flush toilet, a new load is placed on a septic tank / sewage treatment plant of a hospital or facility that receives and purifies feces and toilet paper that is flushed with the wastewater. Can be considered.

Furthermore, in the state where it is less than 80% water-soluble in water at 20 ° C. or less, even if the drain pipe can pass, it will float in the first tank, that is, the septic tank to form scum. However, even if it can be transferred to the second tank, the aeration tank, it cannot be the target of biodegradation by activated sludge, and conversely, it is caught in the nest of aerobic microorganisms in the tank. As a material for the sewage treatment gloves of the present invention, 80% to 100% of its own weight dissolves even in water of 20 ° C or less, which is an essential condition because it impedes convection and impairs the purification function.

It is known that the partially saponified PVA film has a property of rapidly decomposing in water at a saponification degree of 85 to 90 mol% and gradually dispersing and dissolving at a saponification degree of 91 to 97 mol%. .

It is also known that leaving acetic acid groups randomly between PVA molecules weakens the bond between hydrophilic hydroxyl groups and enhances solubility in a low temperature range of 20 ° C. or lower.

The PVA film of the present invention is composed of raw materials that make full use of such known knowledge and technology, and it is necessary that 80% to 100% of its own weight is dissolved in cold water at 20 ° C. or lower. The reason why the condition was set is nothing other than the fact that we wanted to make a brake that should be adhered to so as not to put the maximum load on the wastewater treatment plant.

Then, it should be ensured that the introduction of the wastewater treatment gloves into the flush toilet does not cause deterioration of drainage.

However, if the filth-disposal gloves for carrying out the present invention do not endure the purpose if they are easily broken or melted while touching feces in a wet state, the thickness of the PVA film for carrying out the present invention should be adjusted. It is desirable to increase the strength during use by increasing it by 10 μm or more as compared with the case of polyethylene.

Further, a measure for imparting a temporary water resistance function or a waterproof property to the surface is not rejected as long as it does not impair the cold water solubility.

In this way, the present invention is characterized in that it does not cause a functional disorder even at the terminal treatment plant after use.

[0020]

[Embodiment of the invention]

 Heat-seal and cut into a handbag type that has a thickness of 35 microns and 80% to 100% of its own weight is 20 degrees C or less and is soluble in cold water and has a polyvinyl alcohol film that has an opening for inserting a hand. With a punching machine with a punching die that can be used, punch gloves for both left and right in sequence.

The shape of the fingers at this time may be one having five fingers or a globe type having a thumb and four other fingers. The length of the gloves may be a long length used in the medical field such that not only the hands are wrapped but also part of the arms is covered. Also, the inner surface is embossed so that it can be removed without clinging to the hand.

[0022]

[Effect of the invention]

 At a nursing facility in a facility that accommodates 80 bedridden elderly people, a total of 100 pieces of the filth-disposal gloves of the present invention were used for 2 days, and after changing diapers and removing feces, they were flushed to the flush toilet. The gloves did not puncture or tear during use, and the purpose was achieved.

After one week, the septic tank of the septic tank of the facility was agitated, the lid of the aeration tank was opened, and the suspended matter of the two tanks was scooped up and observed with a 4-mesh wire net. I could not confirm the trace.

The average water temperature in the septic tank during the one-week experiment period was 14.6 ° C, but it was also confirmed that it did not affect the water decomposability of the glove for waste treatment of the present invention.

[0025] Also, a functional contractor of the septic tank carefully inspected and observed the functional effect of applying a load of about 500 g to 100 pieces of the septic tank. Moreover, no evidence of adverse effects on aerobic microorganisms in the activated sludge could be confirmed.

The SS value in the waste water from the septic tank also showed no extreme amplitude.

As described above, the waste bag made of the polyvinyl alcohol film of the present invention can be used like the conventional product, and can be easily dissolved in cold water, so that it does not cause environmental pollution during disposal. There is no fear and there is no problem even if it is flushed to the flush toilet.

The production cost is slightly higher than that of the conventional product, but it leads to a reduction in the public burden of waste treatment, and the total cost including waste treatment can be reduced.
