Detailed ways

The present invention will be further described below with reference to the accompanying drawings.

Embodiment 1: Figure 1, Figure 2, a disposable plastic bag with both opening and closing, with a plastic bag opening retaining ring 1 connected with the plastic bag mouth as a whole, in this embodiment, the plastic bag The bag opening retaining ring 1 is a circular elastic plastic ring, which is connected as a whole when the plastic bag is formed. Between the plastic bag opening retaining ring 1 and the plastic bag, there is an easy-to-tear continuous point-breaking hole line 2, which is convenient to tear off when the opening retaining ring is not needed. There is a sealing zipper 3 under the easy-to-tear continuous-point breaking line, which is convenient for closing the plastic bag after tearing off the opening retaining ring; if the plastic bag is long enough, it is not necessary to easily tear the continuous-point breaking line 2, and it is directly closed with a sealing zipper. According to different uses; for example, in use as a bedpan for bedridden patients, the size of the disposable plastic bag with the plastic bag opening retaining ring is shallow and the mouth is large enough, only the opening retaining ring 1 is sufficient. Another example is for travel, which is also used as a bedpan. The size of the disposable plastic bag with the plastic bag opening and retaining ring needs to be deep enough. Depending on the application, it depends on whether it has an easy-to-tear continuous point-breaking hole line 2, or a sealing zipper 3 and a preset bag. Contains water-retaining agent 4.

Embodiment 2: Fig. 3 shows, the disposable plastic bag with both opening and closing, and the plastic bag opening retaining ring 1 connected with the plastic bag mouth as a whole is a drop-shaped plastic ring, which is another type of the present invention. Continuity in production is easy to achieve; at the same time, the disposable plastic bag with the plastic bag opening retaining ring has a natural handle (handle 5), a special example of use is travel, which is convenient for one hand when it is inconvenient to go to the toilet Complete urination by holding a disposable plastic bag with a plastic bag opening retaining ring. The plastic bag used as a soft urinal should be considered according to different needs. At the same time, it has a water drop-shaped plastic bag opening and retaining ring. 1. The volume size of the plastic bag is sufficient length, and whether it has an easy-to-tear continuous point breaking line according to the situation. 2. Sealing zipper 3 with a pre-set bag with a water-retaining agent.

Example 3: It is another kind of disposable plastic bag with both opening and closing, the structure design of the opening retaining ring of the water drop type plastic bag. Fig. 4 is a schematic diagram showing that the plastic bag opening retaining ring 1 is connected with the plastic bag body in a manner of surrounding, wrapping, interpenetrating and relatively sliding. The plastic bag opening retaining ring has a bend that facilitates fit with the body part. The plastic bag has a water-retaining agent 4 . The plastic bag has a structure 6 that is convenient to be relatively fixed with the opening and retaining ring of the plastic bag. This figure shows a tie, and the tie is also the structure for finally tying the bag mouth. The cross-sectional view of A-A in FIG. 4 shows that the opening retaining ring of the plastic bag has different cross-sections according to different usage scenarios. This schematic diagram is a section of the retaining ring to increase the one-way bending strength.
