[0029] Example 1

[0030] like Figures 1 to 4 As shown, a hot or cold compress water bag includes a bag body and a cover 3. The bag body is provided with an injection port 4. The cover 3 is used to seal the injection port 4 on the bag body. The inner end of the injection port 4 protrudes on one side of the inner wall of the bag body to form a protrusion 4-1. At least one drainage ramp 5 is provided between the top of the protrusion 4-1 and the inner wall of the bag body.

[0031] At the same time, the outer end of the injection port 4 is flush with or concave inwardly with the outer wall of the bag body, forming an inwardly retracted injection port. Figure 4 As shown, the outer end of the injection port 4 is recessed into the outer wall of the bag body.

[0032] The drainage ramp 5 has a drainage groove. In the present embodiment 1, the drainage groove is formed on the drainage ramp 5 by arranging water retaining edges 5 - 1 on both sides of the drainage ramp 5 .

[0033] One end of the drainage ramp 5 located on the inner wall of the bag body is an inlet, and the other end of the drainage ramp 5 located on the top of the protruding portion 4-1 is an outlet. The width of the inlet is greater than the width of the outlet.

[0034] There is a supporting rib 7 between the bottom of the drainage ramp 5 and the bag body, and the extending direction of the supporting rib 7 is the same as the extending direction of the drainage ramp 5. Figure 2 and Figure 4 shown.

[0035] The bag body is U-shaped or C-shaped as a whole and is used for hanging around the neck. The connecting part of the side arms on both sides of the bag body is the top of the bag body, and the opening parts of the side arms on both sides are the bottom of the bag body. The injection port 4 is located at the top of the bag body, and there are two drainage ramps 5, which are respectively located on both sides of the injection port 4 facing the side arms.

[0036] The hot and cold compress water bag of this embodiment 1 is mainly injected with hot water through the injection port 4 for hot compress, so it is also called a hot water bag. It can also be injected with cold water or ice water mixture through the injection port 4 for cold compress.

[0037] The extension direction of the drainage ramp 5 is consistent with the extension direction of the bag body. When the liquid in the bag body needs to be drained, the bag body can be shaken left and right so that the liquid in the bag body can be completely drained out of the bag body with the help of the drainage ramps 5 on both sides, without forming water accumulation at the corner between the protrusion 4-1 and the bag body.

[0038] The bag body includes an inner bag body part 1 and an outer bag body part 2, wherein the inner bag body part 1 is located inside the bag body cavity, and the outer bag body part 2 is located outside the bag body cavity, and the edge of the inner bag body part 1 and the edge of the outer bag body part 2 are sealed together.

[0039] The injection port 4 and the drainage ramp 5 are located on the outer bag body part 2. In this embodiment, the inner bag body part 1 and the outer bag body part 2 are injection molded parts. When the outer bag body part 2 is injection molded, the drainage ramp 5 is integrally injection molded with the bag body to form an integrated form.

[0040] The inner bag body part 1 extends from the inner side to the outer side of the bag body, forming the cold and hot compress surface of the bag body for the neck. The outer bag body part 2 is located away from the outside of the neck, and is used to make the joint edge as far away from the cold and hot compress part, i.e. the human body, as possible.

[0041] This embodiment 1 does not exclude the possibility that water retaining edges 5-1 are not provided on both sides of the drainage ramp, because the PVC bag body and the drainage ramp 5 in the bag body are soft, and the drainage ramp 5 can be pinched by squeezing the bag body to make the two sides of the drainage ramp 5 turn up to form a drainage groove.

[0042] PVC is a soft material, and the cover 3 is a hard material. Therefore, in order to reliably seal the injection port 4, a cover seat 6 is also required in the injection port 4. The cover seat 6 is a hard material and is used to provide an internal thread. The cover seat 6 cooperates with the internal and external threads of the cover 3 to reliably seal the injection port 4. However, when the injection port 4 is located on the outer bag body part 2, which can be made of hard plastic, an internal thread that cooperates with the internal and external threads of the cover 3 can be directly formed in the injection port 4. Of course, it is not ruled out that the cover 3 and the cover seat 6 use other sealing assembly methods to reliably seal the injection port 4.

[0043] The cover seat 6 in the injection port 4 is pre-placed in the injection mold, and is embedded and combined with the injection port 4 by means of rubber encapsulation during the injection molding of the outer bag body part 2. Figure 4 shown.

[0044] The edges of the inner bag body part 1 and the outer bag body part 2 can be joined together by welding or gluing. In addition to high-frequency welding, welding also includes other welding methods, such as hot pressure welding.

[0045] Of course, the present invention does not exclude the possibility that the filling port 4 and the drainage ramp 5 are located at other positions of the bag body when the bag body as a whole is in other shapes.

[0046] Example 2

[0047] like Figures 5 to 8 As shown, a hot and cold compress water bag is basically the same as the hot and cold compress water bag of Example 1, except that the injection port 4 is located on the outer side of the end of one side arm, and there is one drainage ramp 5, which is located on the upper side of the injection port 4. The outer bag body part 2 constitutes the outer side of the bag body, so the injection port 4 and the drainage ramp 5 are also located at the end of the outer bag body part 2.

[0048] When the liquid in the bag needs to be discharged, the liquid in the bag can be completely discharged from the bag by means of the drainage ramp 5 on one side, without forming water accumulation at the corner between the protrusion 4 - 1 and the bag.
