Description

Hot and cold compress water bags Technical Field

[0001] The present invention relates to the technical field of cold and hot compress bags, in particular to a cold and hot compress water bag. Background Art

[0002] The bag body of the conventional cold or hot compress water bag is provided with an injection port, through which cold water or an ice water mixture or hot water is injected for cold or hot compress.

[0003] The bag body of a hot and cold compress water bag is generally made of soft materials, such as rubber, PVC, and silicone. The bag body is generally formed by welding or gluing the edges of the bag parts together, and the joint edges between the bag parts form a joint edge on the bag body.

[0004] Hot and cold compress water bags are designed in various shapes to suit different parts of the body. For cold or hot compresses on the neck, there is a U-shaped hot and cold compress water bag that is hung around the neck. This U-shaped hot and cold compress water bag is also known as a hot water bag on the market. The bag body of this U-shaped hot and cold compress water bag has an inlet sealed by a lid. To ensure the reliability of the lid sealing the inlet, the inlet must be at a certain height. However, to prevent the liquid in the bag from being completely emptied, the inlet cannot protrude from the inner wall of the bag. Therefore, the inlet inevitably protrudes from the bag body, affecting the user experience.

[0005] If the injection port is to be prevented from protruding from the bag body, the injection port will protrude from one side of the inner wall of the bag body to form a circle of protrusions. The protrusions will hinder the complete discharge of liquid from the bag body, and water will accumulate at the corner between the protrusions and the bag body. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a cold or hot compress water bag to prevent the accumulated water in the bag from being unable to be emptied.

[0007] The technical solution adopted by the present invention to solve its technical problems is: a hot and cold compress water bag, including a bag body, with an injection port on the bag body, the inner end of the injection port protrudes on one side of the inner wall of the bag body to form a protrusion, and at least one drainage ramp is provided between the top of the protrusion and the inner wall of the bag body.

[0008] It is further defined that the drainage ramp has a drainage groove.

[0009] It is further defined that both sides of the drainage ramp are provided with water retaining edges for forming drainage grooves on the drainage ramp.

[0010] It is further defined that one end of the drainage ramp located on the inner wall of the bag body is the inlet, the other end of the drainage ramp located on the top of the protrusion is the outlet, and the width of the inlet is greater than the width of the outlet.

[0011] It is further defined that there are supporting ribs between the bottom of the drainage ramp and the bag body.

[0012] It is further defined that the bag body as a whole is U-shaped or C-shaped, with the connection part of the side arms on both sides of the bag body as the top of the bag body, the opening parts of the side arms on both sides as the bottom of the bag body, the injection port is located at the top of the bag body, and there are two drainage ramps, which are located on both sides of the injection port facing the side arms; or, the injection port is located on the outer side surface of the end of one side arm, and there is one drainage ramp, which is located on the upper side of the injection port.

[0013] It is further defined that the bag body includes an inner bag body part and an outer bag body part, the inner bag body part is located on the inner side of the bag body inner cavity, the outer bag body part is located on the outer side of the bag body inner cavity, the edge of the inner bag body part and the edge of the outer bag body part are sealed together, and the injection port and the drainage ramp are located on the outer bag body part.

[0014] It is further defined that the extension direction of the drainage ramp is consistent with the extension direction of the bag body.

[0015] It is further defined that the drainage ramp is integrated with the bag body.

[0029] Example 1

[0030] As shown in Figures 1 to 4, a hot and cold compress water bag includes a bag body and a lid 3. The bag body has an injection port 4. The lid 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 or concave in the outer wall of the bag body, forming an inward-retracted injection port. As shown in Figure 4, the outer end of the injection port 4 is concave in the outer wall of the bag body.

[0032] The drainage ramp 5 has a drainage groove. In this 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] A supporting rib 7 is provided between the bottom of the drainage ramp 5 and the bag body. The extending direction of the supporting rib 7 is the same as that of the drainage ramp 5 , as shown in FIG2 and FIG4 .

[0035] The bag body is U-shaped or C-shaped as a whole and is used for hanging around the neck. The connection 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 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 needs to be drained, the bag can be shaken left and right so that the liquid in the bag can be completely drained out of the bag through 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. The inner bag body part 1 is located inside the inner cavity of the bag body, and the outer bag body part 2 is located outside the inner cavity of the bag body. The edges of the inner bag body part 1 and the edges 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 hot and cold 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 hot and cold compress part, that is, the human body, as possible.

[0041] This embodiment 1 does not exclude the possibility of not setting water retaining edges 5-1 on both sides of the drainage ramp, because the PVC bag body and the drainage ramp 5 inside 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, while the lid 3 is a hard material. Therefore, to reliably seal the injection port 4, a cap seat 6 is also required within the injection port 4. The cap seat 6 is made of a hard material and is used to provide internal threads. The cap seat 6 mates with the internal and external threads of the lid 3 to reliably seal the injection port 4. However, if the injection port 4 is located on the outer bag member 2, which can be made of hard plastic, internal threads that mate with the internal and external threads of the lid 3 can be directly formed within the injection port 4. Of course, other sealing assembly methods for the lid 3 and the cap seat 6 are not excluded 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 when the outer bag component 2 is injection-molded, as shown in FIG4 .

[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. Welding includes other welding methods besides high frequency welding, such as hot press welding.

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

[0046] Example 2

[0047] As shown in Figures 5 to 8, a hot and cold compress water bag is essentially the same as the hot and cold compress water bag of Example 1, except that the inlet 4 is located on the outer side of the end of one side arm, and there is a single drainage ramp 5 located above the inlet 4. The outer bag body component 2 constitutes the outer side of the bag body, so the inlet 4 and drainage ramp 5 are also located at the end of the outer bag body component 2.

[0048] When the liquid in the bag needs to be drained, the liquid in the bag can be completely drained out of 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.
