Description

[Detailed Description of the Invention] This paper describes a method of manufacturing a urine bag to which a bag made of plastic film is attached, which enables stable, firm, and stylish welding to the inlet body of the bag. The invention will be explained in detail based on embodiment figures.

Figures 1 and 2 show a urine bag manufactured by the method of the present invention, in which an upper opening 2 of a bag body 1 made of a plastic sheet is welded to a roughly oval-shaped inlet body 3 made of a hard plastic material. It is.

The inlet body 3 and the opening 2 are welded across the front and rear sides with heat welding parts 4a and 4b, and spot welds 5a and 5b are formed at the corners of the left and right sides, respectively.

To manufacture this bag, one corner of the upper opening of the plastic bag 1 as shown in FIG. 4 is cut diagonally from the chain line 7, and the cut part is heat sealed 8. Make the opening a little wider than the lower cylindrical part 3 of the inlet body (Fig. 5). Next, the mouth of the bag body is fitted into the lower part of the injection body 3 as shown in Fig. 6, and a part of the front or rear corner of this fitted part, in fact, a part of the front corner is first spot welded 5aL to the injection body. After this welding, the rear part of the bag opening is pulled and a part of the rear corner is spot welded 5b to the inlet body. After spot welding to the filler body at the mouth of the bag in this manner, as shown in FIG. 4b.

In addition, in the illustration, reference numerals 63 and 6b indicate fastener protrusions and grooves formed across the upper inner surface of the bag so that the bag can be closed by fitting these into each other.

In order to manufacture this kind of floor bag, the plastic opening upper part shown in FIG. In the conventional method, the opening of the bag is welded to the inlet body, but with this method, it is impossible or difficult to weld the opening of the bag to the front and rear of the inlet body, and as shown in FIG. There are portions a and b at the front and rear of the inlet body where the bag body is not welded. Therefore, the welding of the bag body to the injection port body is uncertain and gives a feeling of anxiety.

In addition, since the bag body is thermally welded by fitting the dog-sized opening of the cylindrical bag itself into the injection port body, the opening of the bag must be significantly heat-shrinked during heat welding.
As a result, many wrinkles occur in the bag, making it look unsightly.

However, in the present invention, after fitting the opening of the bag in which one corner of the opening is diagonally canted and the cut portion is heat-sealed to the inlet body, the front or rear part of the bag opening, preferably first, is fitted. Spot welding the front part to the inlet body 5a
Next, the rear part of the bag mouth is also spot welded 5b, and then the bag mouth is welded to the filler body using a hot press plate, so that the front and rear parts of the mouth of the bag body are also firmly welded to the filler body. Moreover, thermocompression bonding using the heat suppression plates 9a and 9b is easy, and a floor bag can be manufactured without any anxiety.

In addition, the opening of the bag body was cut and sealed at the corner as mentioned above, and the opening was only about one size larger than the inlet body, so when welding it with a hot press plate, A product with almost no wrinkles, good appearance, and high commercial value can be obtained.

Note that the front and rear parts of the bag opening are spot welded in two places on the left and right, and there are some unwelded parts left between the left and right spot welds 5a and 5a and between 5b and 5b, but these are essentially no welds. No problem, rear spot welding part 5b,
By making the width between 5b a little thicker, this gap can be used as an air leak opening during urination.

The floor bag manufactured by the method of the present invention is used for urinating into the bag by applying the mouth of the injection port to the private part. At this time, a hardening agent is placed in the bag in advance to harden the urine into a gel-like state. After urinating, the bag is sealed by fitting the protruding stripes 6a and the groove strips 6b, which serve as fasteners, to prevent leakage of urine and odor.

Claims (1)

[Claims] By cutting the corners of a plastic bag diagonally and heat-sealing the cut parts, the opening is made about one size wider than the cylindrical part of the hard inlet body, and then the opening of this bag is After fitting the cylindrical part of the inlet body and spot welding the front and rear openings of the bag to the front and rear of the inlet body, attach the left and right sides of the bag opening to the left and right sides of the inlet body on a hot pressing plate. A method for producing a urine bag, characterized in that the urine bag is heat-welded.
