Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a urine bag in which a plastic film bag is attached to a hard plastic filler body, and the bag body can be welded to the filler body in a stable manner and with good appearance. The present invention will be described in detail below with reference to embodiment figures regarding the manufacturing method thereof.

Figures 1 and 2 show a urine bag manufactured by the method of the present invention, in which the upper opening 2 of a bag body 1 made of a plastic sheet is welded to a substantially elliptical inlet body 3 made of a hard plastic material. It has been done. The inlet body 3 and the opening 2 are welded across the front and rear sides with heat welding parts 4a and 4b, and the corner parts of the left and right sides are welded with spot welds 5, respectively.
a, 5b are done.

To manufacture this bag, one corner of the upper opening of a plastic bag 1 as shown in Fig. 4 is cut diagonally from the chain line 7, and the cut part is heat-sealed 8, thereby forming the bag. The opening 1 is made to be slightly larger than the lower cylindrical portion 3 of the inlet body (Fig. 5). Next, the opening of the bag body is fitted into the lower part of the injection body 3 as shown in FIG. 6, and the front or rear corner of this fitted part, in fact, the front corner part is first spot welded 5a to the injection body. ,
After this welding, the rear part of the opening of the bag body is pulled and the rear corner part is spot welded 5b to the inlet body. After the mouth of the bag body is spot-welded to the inlet body in this manner, the left and right side parts of the bag mouth are thermally welded 4a to the inlet body using a pair of heat pressing plates 9a and 9b as shown in FIG. , 4b.

In addition, in the illustration, the symbols 6a and 6b are
Fastener protrusions and grooves are formed across the upper inner surface of the bag, and these can be fitted together to close the bag.

In order to manufacture this kind of urine bag, up until now, a plastic opening upper part as shown in FIG.
As shown in the figure, 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. As shown in Figure 8, there are portions a and b where the bag is not welded at the front and rear of the inlet body. Therefore, the welding of the bag body to the inlet body is uncertain, which gives a feeling of anxiety. Not only that, but the large diameter opening of the cylindrical bag itself is fitted into the inlet body and heat welded, so the opening of the bag must be significantly heat-shrinked during heat welding. Many wrinkles appear on the plant, giving it an unsightly appearance.

However, in the present invention, after fitting the opening of the bag in which one corner of the opening is cut diagonally and the cut portion is heat-sealed into the inlet body, the front or rear part of the bag opening, preferably, first The front part is spot welded 5a to the inlet body, and then the rear part of the bag mouth is also spot welded 5b, and then the bag mouth is welded to the inlet body using a hot press plate, so that the front part of the mouth part of the bag body and The rear part is also firmly welded to the inlet body, and can also be easily heat-pressed using heat-pressing plates 9a and 9b.
You can create a urine bag that doesn't make you feel anxious.

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, there was almost no part of the bag. It is possible to obtain a product with good appearance and high commercial value without wrinkles.

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 There is no problem and by making the width between the rear spot welds 5b a little larger, this gap can be used as an air leak port during urination.

The urine bag manufactured by the method of the present invention is used for urinating into the bag by applying the mouth of the inlet body 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 fastener protrusions 6a and grooves 6b to prevent leakage of urine and odor.

Claims (1)

[Claims] 1 Cut the corner of the plastic bag diagonally and heat seal the cut part to make the opening about one size larger than the cylindrical part of the hard inlet body, and then cut the opening of the bag. 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, apply the left and right sides of the opening of the bag to the left and right sides of the inlet body using a hot press plate. A method for producing a urine bag characterized by heat welding.
