ABSTRACT:
BACKGROUND OF THE INVENTION
This invention relates to a men's disposable urine holding bag adapted to be suitably used by, for example, bedridden patients, aged men or incontinent patients.
Japanese Utility Model Application Disclosure No. 1985-69114 describes a men's disposable urine holding bag dimensioned to be longitudinally long and comprising a liquid-pervious topsheet, a liquid-impervious backsheet and a liquid-absorbent core disposed between these two sheets. The bag is formed at its upper end with a penis insertion mouth and the penis is inserted into the bag through the insertion mouth.
In the bag disclosed in the aforesaid Disclosure, the portions of the top- and backsheets extending outward beyond the peripheral edge of the core are continuously bonded together along the bond zone extending along the longitudinally opposite ends as well as the transversely opposite side edges of the bag by means of hot melt adhesive or heat-sealing technique. Such continuously bonded periphery creates a feeling of discomfort and irritation against the wearer when the bonded periphery is in contact with the wearer, since the bonded periphery might be excessively hardened, depending on a width of the bonded periphery.
SUMMARY OF THE INVENTION
An object of the invention is to provide a men's disposable urine holding bag that is designed so as to be free from a possibility that a bond zone of the bag might create a feeling of discomfort and irritation against the wearer and an amount of discharged urine might leak out through the bond zone.
According to this invention, there is provided a men's disposable urine holding bag comprising: a flexible liquid-impervious base sheet; a mouth for insertion of the penis defined by bonding transversely opposite side edges of the base sheet; a body fluid absorbent panel attached to an inner side of the base sheet; the side edges of the base sheet being intermittently bonded to define a bond zone along the side edges of the base sheet; and the bond zone having a water pressure resistance of 50-1500 mm.
With the men's disposable urine holding bag according to this invention, there is no possibility that the bond zone of the bag might be excessively hardened and therefore create a feeling of discomfort and irritation against the wearer and an amount of urine having reached the bond zone of the bag might permeate the bond zone.
