Description

Shapeable hot and cold pack

This case relates to a hot and cold bag, especially a shapeable hot and cold bag.

According to the occasions where I use hot and cold bags, more common ones, such as mattresses, cushions, pillows, chair cushions, eye masks, etc., can be described as dazzling.

The conventional hot and cold packs are mainly divided into two categories, one of which is to fill the bag with liquid, and the other is to fill the bag with liquid and add a block lining to make the bag under negative pressure. Basically, the first type of hot and cold bag is filled with liquid in a hot and cold bag, and a thickener is added or the bag is further divided into a plurality of small independent partitions, thereby improving the disadvantage that the liquid is naturally sag due to gravity attraction. The second type of hot and cold bag has a negative pressure inside, and uses atmospheric pressure to force the liquid to reside in the pores of the inner liner, thereby improving the disadvantage of the natural vertical flow caused by gravity attraction.

Because water is cheap, environmentally friendly, and easy to obtain, and more importantly, water is hotter than heat, it is naturally the best cooling or heating medium; but water is both fluid, so it has no fixed shape and is subject to gravity. Attraction will cause a sag. This feature causes the above-mentioned first type of hot and cold pack to cause floating instability when used as a cushion for sitting and lying. In fact, when used as a hot and cold pack, the liquid cannot reside where it is needed, resulting in poor results. In addition, when the tension is tied, the bag body will swell and cannot conform to the body shape, which is troublesome. When the second type of hot and cold bag is made of sponge as the inner lining, the weak support force of the sponge is compressed when the bag body is compressed, the liquid will be compressed from the sponge, and the negative pressure state will be lost, and the liquid will be produced. Vertical. In order to improve the aforementioned drawbacks, the prior art has used a three-dimensional fabric lining to replace the sponge, but the three-dimensional fabric lining still has the following disadvantages in production and use:

1. The three-dimensional fabric lining is expensive and cannot be widely used in hot and cold bags.

2, three-dimensional fabric lining weaving is not easy, and the general thickness is about 1cm, so that the inside of the bag body has a limited space of negative pressure, unable to fill enough liquid.

3. When the three-dimensional fabric lining is cut, the falling segmental monofilament is difficult to remove, causing troubles in subsequent filling of the liquid, and even sticking to the sealing position of the bag body, so that the bag body cannot be completely sealed.

4. The three-dimensional fabric lining is a sheet-shaped body, which cannot allow the user to move or adjust the thickness according to his needs, so that it can truly conform to the body shape to achieve the best cold and hot compress effect.

5. The production of hot and cold bags for three-dimensional fabric lining is difficult because the air that resides inside is difficult to discharge, and it is not easy to achieve a negative pressure state.

As shown in the patent application No. 585054 and No. I293601 (corresponding to U.S. Patent No. 6,622,781) owned by the applicant of the present application, a piece of a spacer fabric is installed in the bag body, and the inside of the bag body is formed. Negative pressure, in order to use atmospheric pressure to press the liquid inside the three-dimensional fabric to make the liquid not sag; but because the thickness of the three-dimensional fabric is mostly below 1cm, and the cost is high, the thickness of different parts of the bag cannot be adjusted to fit the human body. The body shape makes the hot and cold pack more efficient.

In addition, as shown in the patent application No. M304954 (corresponding to the Chinese Patent No. ZL 200520119277.2) owned by the applicant of the present application, it is a device in which a piece of foam is placed in the bag body and allowed to be in the bag body. The part is generally formed with a negative pressure so as to compress the liquid in the internal cavity of the bulk foam by atmospheric pressure, so that the liquid does not sag; although the sponge is superior in cost and thickness to the three-dimensional fabric, the supporting force is not as good as the three-dimensional fabric, when the sponge The weak support force shrinks when the bag is under pressure, causing the liquid to flow out of the sponge, and the bag body is inflated to lose the negative pressure state, and the liquid will flow and sag, and the thickness of different parts of the bag body cannot be adjusted, so that More suitable for the body shape, making hot and cold compress more efficient.

The main purpose of the present invention is to provide a shapeable cold and hot compress bag, wherein the support inside the bag body is a granular body with pores, and the user can squeeze the bag body at will, thereby pushing the granular support and simultaneously moving the particles. The shape of the support and the liquid contained in the pores, thereby adjusting the shape of the hot and cold pack to make it more conformable to the human body.

Another object of the present invention is to provide a shapeable cold and hot bag in which the granular support and the liquid contained in the pores thereof are pressed and fixed by atmospheric pressure under a negative pressure without sag.

In order to achieve the foregoing objectives, the technical means adopted in the present invention is to provide a shapeable cold and hot compressing bag, which comprises: a soft sealed bag body which is impervious to water;

Figure 8 is a perspective view of the second embodiment of the liquid control valve of the present invention combined with the opening of the bag body.

As shown in FIG. 1 to FIG. 4, basically, the hot and cold bag of the present invention is composed of a bag body 1, a plurality of granular supports 2, and a liquid 3.

As shown in FIG. 1, the bag body 1 is a soft material that is impervious to water, such as, but not limited to, a high molecular polymer, for example, selected from the group consisting of polyvinyl chloride (PVC), polyurethane (PU), and polyethylene-coated polyamine (PE/). Nylon), vinyl acetate (EVA), hydrogenated styrene thermoplastic elastomer (SEBS), silicone (Silicon), and the surface of the polymer has a fabric attached to increase the texture of the bag 1 Aesthetic.

The inner volume of the bag body 1 is larger than the total volume of the granular support 2 and the liquid 3, so that the support 2 and the liquid 3 are accommodated in the inner space of the bag body 1. As shown in FIG. 1 , after the bag body 1 accommodates a plurality of granular supports 2 and an appropriate amount of liquid 3, the inside of the bag body 1 exhibits a negative pressure state. At this time, the bag body 1 is pressed by the external atmospheric pressure, and further The confined granular support 2 and the liquid 3 contained in the pores 21 are in a certain area inside the bag body 1, so that the liquid 3 is not attracted by gravity to generate a vertical flow.

Since the bag body 1 has a margin space 11 therein, the margin space 11 is sufficient to accommodate a small amount of liquid 3 removed by the pores 21 of the granular support 2, so that the bag body 1 remains slack and soft in use, so as to provide close It fits the body shape and achieves the best cold and hot compress effect.

The particulate support 2 is a high molecular polymer such as polyethylene (PE), polyurethane (PU), polypropylene (PP), acrylonitrile-butadiene-styrene copolymer (ABS), polyethylene to benzene. Made of dicarboxylic acid ester (PET) or polyamidamine (PA), or the polymer blend is made of a far-infrared radiation material such as zirconia, tantalum or bamboo charcoal. Each of the particulate supports 2 has at least one aperture 21, as shown in Figures 2a and 2b, such as but not limited to a tubular or hollow spherical shape, since the particulate support 2 is a material of comparable hardness, for example Shore hardness (ShoreA) is 60 A or more. Therefore, when pressed by an external force, it has appropriate supporting force and elasticity, so that the amount of liquid 3 removed from the pores 21 of the granular support 2 is small to match. The remaining space 11 of the bag body 1 keeps the cold and hot bag in a state of being relaxed and soft, so that it can closely conform to the body shape and achieve the best cold and hot compress effect.

The liquid 3 is, for example but not limited to, water. To prevent freezing or hardening, an appropriate amount of an antifreezing agent such as salt, alcohol, propylene glycol or glycerin may be added. At the same time, the liquid 3 mainly resides in the pores 21 of the respective particulate supports, and a small amount resides in the gap after the stacking of the particulate supports 2.

When the cold and hot bag is manufactured in the present case, the granular support 2 and the liquid 3 can be filled through the filling port of the bag body 1, and the air in the bag body 1 is driven by the liquid 3, and the excess liquid 3 is removed at the same time, and the inside of the hot and cold bag is presented. When the proper negative pressure state is reached, the filling port can be closed. By controlling the discharge amount of the liquid 3, various different negative pressure levels can be easily obtained to meet the individual requirements of different products. For example, the greater the discharge amount of the liquid 3, the greater the degree of negative pressure, so that the more the granular supports 2 and the liquid 3 It is not easy to be moved, and the opposite bag body 1 is relatively soft.

As shown in FIG. 3, the user pushes both sides of the bag body 1 with both hands, so that the internal granular support 2 and the liquid 3 contained in the pores 21 therein move in the middle to form the center of the bag body 1. Forming a bulging shape.

As shown in FIG. 4, the cold heat pack is wrapped around the back heel of the human body, and the granular support 2 in the bag body 1 is squeezed by hand, thereby pushing the granular support 2 and simultaneously moving the same. The granular support 2 and the liquid 3 contained therein are arranged in the pores 21 to adjust the shape of the cold heat pack to fit the rear heel, thereby achieving an optimum cold or hot compress effect.

5 is a schematic view of a second embodiment of the cold and hot pack of the present invention, the bag body 1 includes at least one openable and closable opening 12, and the openable and closable opening 12 includes a liquid control valve 4 composed of a polymer polymer injection molding. The filling or discharging of the liquid 3 can be controlled by the liquid control valve 4. The liquid control valve 4 has a fixing member 41 coupled to the opening 12. The fixing member 41 is internally provided with a grid 411 to prevent the granular supports 2 from falling out of the bag body 1 through the opening 12, and the external device is separately provided. There is a joint portion 412 such as, but not limited to, a threaded section for attaching an on-off valve 42. The on-off valve 42 is provided with a slidable valve cover 421 which is opened when the valve cover 421 is pulled out. Conversely, when the valve cover 421 is pushed in, the on-off valve 42 is closed.

6 is a schematic view of the second embodiment of the cold-hot pack filling liquid. When the bag body 1 is filled with the liquid 3, the bag body 1 is removed from the switch valve 42 to fill the liquid 3, and the liquid 3 is filled and opened from the opening 12. After the outflow, the on-off valve 42 is then replaced, and the on-off valve 42 is attached to the joint portion 412 of the fixing member 41 provided in the opening 12 so that the liquid 3 does not flow out of the liquid control valve 4.

7a and 7b are schematic views showing the second embodiment of the cold-hot pack, after filling the liquid, and removing excess liquid, so that the bag body exhibits a negative pressure state. First, the opening 12 of the bag body 1 filled with the liquid 3 is turned downward, and the valve cover 421 of the on-off valve 42 is pulled apart, so that the liquid 3 is discharged downward due to the pressure of gravity and atmospheric pressure until the atmospheric pressure cannot recompress the particles. When the volume of the support 2 is shaped, the liquid 3 is no longer discharged; then, the on-off valve 42 is locked, and the valve cover 421 is pushed in, so that the on-off valve 42 is closed.

At this time, the inside of the bag body 1 has been in a negative pressure state; of course, the user can also press the granular support 2 according to actual needs, so that the liquid 3 continues to flow out through the opening 12, so that the inside of the bag body 1 exhibits a higher negative pressure. . At this time, the granular support 2 and the liquid 3 are all pressed by the atmospheric pressure without sag, and the granular support 2 can be squeezed and displaced to shape the shape of the desired bag 1.

FIG. 8 is a schematic view showing the second embodiment of the liquid control valve of the present invention combined with the opening of the bag body. The liquid control valve may also be a clamp 43 which can be removed from the opening 12 of the bag body 1 to fill the liquid 3 After the liquid 3 is filled and flows out from the opening 12, the opening 12 of the bag body 1 filled with the liquid 3 is turned downward as described above, so that the liquid 3 is discharged downward due to the pressure of gravity and atmospheric pressure until the atmospheric pressure cannot be compressed. When the volume of the granular support 2 is small, the liquid 3 is not discharged again. Then, after the opening 12 is folded back, the jig 43 is clamped to the reflexed opening 12 so that the liquid does not bleed out.

In addition, the shape of the bag body 1 is not limited to the example disclosed in the drawings, and it can also be made into a cute shape such as a cartoon doll, or installed inside a pile pillow to create a more friendly use interface. Further, the far-infrared radiation ore may be mixed in the granular support 2 or mixed with the liquid 3, so that after the bag 1 is heated, the heat energy can be converted into sufficient far-infrared rays to produce an optimum heat application effect. In particular, in the negative pressure state, most of the liquid 3 is contained in the pores 21 of the granular support 2, and the pores 21 can block the convection of the liquid 3, thereby reducing the heat energy of the cold and hot pack and the outside. Exchange, greatly extend the maintenance time of the hot and cold pack temperature.

Therefore, through the implementation of the present case, the gain of the present invention is that the cold and hot compressing bag utilizes atmospheric pressure and recombines the new correspondence between the components, thereby generating a plurality of new functions, completely overcoming the conventional cold and hot compressing bag, unable to stably support, and high contact pressure. The sealing edge is prone to bursting and the liquid will sag. The liquid in this case is completely distributed along with the granular support with pores. By pushing the moving of the granular support in the moving bag, the shape of the bag can be shaped to fully fit the body shape of any part of the body. Good cold or hot compress effect. In addition, since the liquid system is saturated in the pores of the particulate support, the particulate supports hinder the convection of the liquid, slowing the movement of the liquid energy, and thereby greatly prolonging the time of cold or hot application.

Especially in advance, this case has stable support ability, no drooping and maximum liquid content, in addition to being used as an anti-decubitus mattress, hot and cold pad, insulation pad, water bed and mouse pad, when sleeping in summer When the mattress is used instead of the air conditioner, in addition to the environmental protection source, the indoor air circulation can be maintained, which is a breakthrough in the hot and cold bag product.

The disclosure of the present invention is a preferred embodiment. Any change or modification of the present invention originating from the technical idea of the present invention and being easily inferred by those skilled in the art will not deviate from the scope of patent rights of the present invention.
