Description

SPECIFICATION Portable device for disposing of water retaining excreta The present invention relates to a portable device for disposing of water retaining excreta such as urine or vomit.

There is known conventionally a devicefor disposing of water retaining excreta as shown at B in Figure 7. The device B is for use in disposal of urine.

The device B comprises a sheet bag 02 having a receiver 01 disposed at an opening thereof.

Designated at or is a fastenerfor closing the opening of the sheet bag 02 after use of the device B and for opening at the time of washing the device B. With such an arrangement, a granularabsorbent04 contained in an absorbent bag 03 is entered from the receiver 01 into the sheet bag 02. The sheet bag 02 is repeatedly usable as a device for disposing of water retaining excreta.

The conventional device B has the shortcomings that the provision ofthe receiver 01 is not only expensive, but is inconvenient because the device B cannot be compactly folded with thin form and bulk.

Moreover, with regard to the operations needed two be performed by the user, the conventional device B has the shortcomings that time and labour need to be spent by the user in introducing the granular absorbent 04 by tearing open the absorbent bag 03, and also need to be spent in washing the sheet bag 02 afterthe use thereof.

According to the present invention, however, a portable device for disposing of water retaining excreta comprises: (a)a water impermeable sheet bag having an end provided with an opening, and the other end closed; and (b) a water fixing material previously housed within said sheet bag.

It will be appreciated that, by avoiding the need for a receiver and by already providing the waterfixing material in the sheet bag, the portable device ofthe present invention can be compactly folded with thin form when carried by the user and can be manufactured with low cost, the cost indeed being sufficiently iow for the portable device to be disposable thereby avoiding the need for time-consuming and troublesome pre-treatment or after-treatment by the user.

Said sheet bag may be formed of a water impermeable resin (or plastics material) such as polyvinyl chloride. Said sheet bag may be shaped as a rectangle, having initially been shaped asa cylinder with one end being cut to provide the opening and the other end being closed byfor example thermal sealing.

Said water fixing material may be formed of a water absorbent and water soluble paper. The water absorbent may be capable of absorbing and fixing water from the water retaining excreta in a jelly-like form and may be polyacrylic acid soda. The water soluble paper may be carboxylmethylcellulose and wood pulp.

Preferably, the portion of said sheet bag close to its opening is provided with a closure, and said closure is a releasable fastener including a male portion and a female portion receiving said male portion.

Also preferably, said water fixing material is formed as a rectangle which has been folded in half to fit within that half of said sheet bag by its closed end; said sheet bag has itself been folded in half so that its opening overlies its closed end to form a compact package; and two of said compact packages are housed within a closable bag in such a manner that, when said closable bag has been folded in half to bring an openable end thereof into overlying relationship with a closed end thereof, a respective one of said compact packages is housed within each of said halves of said closable bag to form a compact assembly.

A portable device in accordance with the present invention, and two ofthe portable devices in a compact assembly with a closable bag, will now be further described, by way of example only, with reference to the accompanying drawings, in which Figure lisa front elevational view, partly broken away, of a portable device for disposing of water retaining excreta according to the present invention; Figure2 is a cross-sectional view taken along line ll-ll of Figure 1; Figure 3 is a perspective view of a waterfixing member of the portable device; Figure 4 is an enlarged cross-sectional viewtaken along line IV-IV of Figure 3; Figure 5 is a front elevational view, partly broken away, of a closable bag containing two of the portable devices;; Figure 6 is a partially cross-sectioned view taken along line VI-VI of Figure 5; and Figure 7 is a perspective view of a conventional portable device for disposing of water retaining excreta.

A portable device A for disposing of water retaining excreta comprises a sheet bag 10 and a water fixing member 20. The sheet bag 10, formed as a rectangle and made of a water impermeable resin sheet, has an end provided with an opening 1 Oa, the other end being thermally sealed. The sheet bag 10 is, for example, made of sheet polyvinyl chloride resin. The sheet bag 10 may be formed from a cylindrical body extended longitudinally and cut in the prescribed length. One end of the cut portion is thermally sealed and the other end is opened to form the opening 1 0a. A closure is provided at the portion close to the opening 1 Oa.The closure is a linear fastener 11 provided at an inner surface of the sheet 10 and composed of a male portion 1 a and a female portion llbforclosing the opening 1Oa.

The waterfixing member 20 is made of a paper or a cloth including a water absorbent capable of absorbing and fixing water in a jelly-like form. The fixing member 20 according to the present embodiment comprises an absorbent 21 and water soluble papers 22, 22 sandwiching the absorbent 21 therebetween and thereafter the fixing member 20 is folded in two as shown in Figure 3. The water absorbent21 is made ofpolyacrylicacid soda, the water soluble papers 22, 22 are made of carboxylmethylcellulose and wood pulp. The water fixing member 20 is housed in the bottom half ofthe sheet bag 10 before use of the portable device A.

To make a compact package, the portable device A is folded in half. Preferably, two of the compact packages are housed in a portable bag 30 having an opening 30a in a manner as shown in Figure 5. The portable bag 30 is then itself folded in two in the same width as that of the water fixing members 20 to thereby form an easily carried compact assembly.

The opening 30a ofthe portable bag 30 has as adhesive 31 applied by the opening 30a to enable repeated closing ofthe opening 30a.

Operation ofthis embodiment ofthe present invention will be described here.

The opening 30a ofthe portable bag 30 is opened to pick up from the portable bag 30 one ofthe portable devices A. Then, the fastener 11 of the portable device A is released to open and slightly inflatethe sheet bag 10 for enabling urine to be passed through the opening 1 Oa. The sheet bag 10 is held in the manner of pushing from outside and widening the sheet bag 10 by one hand which presses against a resilient returning force of the fastener 11 and thereby separates the male portion 11 a from the female portion 11 btoform a rounded opening through which urine can easily be passed.

Then, urine passed from the opening 1 Oa into the sheet bag lOis fixed like a jelly form bythewater fixing member 20. After urine is passed, the portable device A is resealed by closing the fastener 11 and is then thrown away, for example in a wastebasket or other suitable container.

As mentioned above, the portable device A according to the present embodiment comprises a combination of the impermeable sheet bag 10 having the opening 1 Oa and the water fixing member 20 capable of absorbing andfixing water in the water retaining excreta in the form of jelly so that the portable device A is simple to make and use being both inexpensive and compact.

Although the material of the sheet bag loins polyvinyl chloride resin,thesheet bag may be another impermeable resin and may not be a resin sheet. The water absorbent 21 and the water soluble paper 22 is not limited to polyacrylic acid soda and carboxylmethylcellulose. The fastener 11 may be replaced by a holder, a code or the like, orthe opening 1 Oa may be merely closed by hand.

Although the portable device A is housed in the portable bag 30, the portable bag 30 is not always required.

The portable device according to the present invention is intended to be used as a urinal fora patient, an aged person, or a handicapped person, or an outdoor urinal for use in an outdoor practice field, a campground, ora baseball ground, ora urinal in a car whilst driving, or as a disposerforvomitted material.
