Description

Hot and cold bag

This case relates to a hot and cold bag, especially a hot and cold bag with shaping function.

According to my use of hot and cold bags, more common, such as mattresses, cushions, pillows, cushions, eye masks, protective gear, etc., can be described as dazzling.

The drawback of the conventional hot and cold pack is that the liquid in the bag is attracted by gravity and causes a vertical flow problem, and the general solution is divided into two categories, one of which is to fill the bag with a gel to delay the gel. The second is to fill the bag with liquid and add a supporting lining, and form a negative pressure state in the bag, so as to limit the flow of liquid in the bag by atmospheric pressure.

Basically, these two types of hot and cold bags are used to overcome the problem of internal liquid gravity sag, but they can not overcome the shortcomings of the cold and hot bag temperature maintenance time and the inability to shape. For example, in U.S. Patent No. 4,700,706, it discloses a hot and cold bag with a silicic acid gel as a content, and the vacuum-packed bag can be kneaded; however, since the gelatin is a gel And the specific heat is lower than water, so the heat transfer between the cold and hot pack and the outside is fast, and the temperature is not easy to maintain; further, the contents disclosed in the patent, such as the gel, do not have supporting force, and cannot block the heat convection. Heat conduction; since the gel body has no supporting force, it has no shaping function under the compression type, so that the temperature of the cold heat pack is maintained for a short time.

In addition, as shown in Japanese Patent Laid-Open No. 8-84742, the contents thereof are Round pellets and liquids, because the bag system of the hot and cold bag is made of water vapor permeable material, not water-tight material, and is not sealed by vacuum, so there is no shaping function.

Therefore, how to provide a cold and hot bag with a long temperature maintenance and a shaping function is a difficult problem to be overcome by related companies.

The main purpose of the present invention is to provide a cold and hot bag, which is sealed after being subjected to a vacuuming process, so that the heat storage material in the content or the heat storage unit is mostly filled in the bearing space of the plurality of carrying units, and the storage The thermal material or the remainder of the thermal storage units are located outside of the carrying units to form a lubricating function so that the carrying units can be moved when the bag is squeezed to achieve a shaping function.

The secondary object of the present invention is to provide a hot and cold pack, wherein the heat storage material or the heat storage unit comprises a water-absorbing polymer and a second component of the first component, and the first component has high water absorption. The molecular polymer has a first weight, the second component of water has a second weight, and the first weight accounts for 3% to 15% of the sum of the first weight and the second weight, so that the heat storage material Or the heat storage units have almost no fluidity, thereby reducing the heat convection of the heat storage material or the heat storage units, thereby prolonging the maintenance time of the hot and cold pack temperature, and alleviating the heat absorption and heat release rate of the human body to achieve the most Mild cold compress and hot compress effect.

Another object of the present invention is to provide a cold and hot pack, wherein the heat storage material or the heat storage units are mostly accommodated in the bearing space of the load bearing unit, and the outer shell of the load bearing unit further limits the heat storage. The heat convection of the materials or the heat storage units to slow the movement of the heat storage materials or the energy of the heat storage units, thereby substantially prolonging the maintenance time of the cold pack temperature.

A further object of the present invention is to provide a hot and cold pack, wherein the load bearing unit has When the bag body is pressed, the heat storage material or the heat storage unit is not easily removed from the load bearing unit, so that the bag body does not bulge when pressed, and the pressure type can be tied. It is conducive to the treatment of sprain swelling.

Another object of the present invention is to provide a hot and cold pack, wherein the heat storage material or the The heat storage unit has almost no fluidity, and most of it is accommodated in the load bearing unit. Since the bag body is sealed after being subjected to a vacuum process, when the bag body is damaged, the contents are not easily removed from the damaged bag. The body flows out without causing skin burns or frostbite.

In order to achieve the above objectives, the technical means adopted in this case provide a kind of hot and cold a bag comprising a water-impermeable soft bag and a content contained in the soft bag, the content comprising a heat storage material comprising a first component of a water-absorbing polymer and a second And a plurality of carrier units each having at least one bearing space; wherein the soft bag system is sealed by a vacuum process to seal the bag body, and the vacuuming process enables the bearing space of the carrier units A portion of the heat storage material is disposed and the remainder of the heat storage material is retained outside of the plurality of carrier units such that the contents form a shapeable structure within the water impermeable flexible bag.

Another technical means adopted in the present case is to provide a cold and hot compress bag, which comprises a a soft bag body which is a water-tight bag body; and a content contained in the soft bag body, and the content includes a heat storage material having a plurality of heat storage units, the heat storage units The first component of the water-absorbing polymer and the second component of water; and a plurality of carrier units each having at least one bearing space; wherein the soft bag system is sealed by a vacuum process, the bag is sealed Vacuuming the program to accommodate the storage spaces of the carrier units A portion of the heat storage unit is retained outside of the plurality of carrier units such that the contents form a shapeable structure within the flexible bag.

In order to further reveal the specific technical content of the present case, first, please refer to the drawings, wherein: FIG. 1 is a perspective view of the cold and hot bag of the present invention; FIG. 2a and FIG. 2b are cross-sectional views of two different embodiments of the bag body; FIG. 3a and FIG. 3 is a perspective view of two different embodiments of the carrying unit of the present invention; FIG. 4 is a perspective view of the granular load bearing unit and the heat storage material inside the cold and hot compressing bag after being moved and shaped; and FIG. 5 is adapted to the human body after the cold and hot compressing bag is adjusted A perspective view of the heel.

As shown in FIG. 1 to FIG. 5, basically, the hot and cold pack of the present case comprises a bag body 1 and a content 2. The content 2 includes a heat storage material 3 formed by combining superabsorbent polymers and water, and a plurality of particulate load cells 4.

The bag body 1 is a soft material that is impervious to water, for example, selected from the group consisting of polyvinyl chloride (PVC), polyurethane (PU), polyethylene bonded polyamine (PE/Nylon), vinyl acetate (EVA), and hydrogenated styrene thermoplastic. It is made of high molecular weight polymer such as elastomer (SEBS) or silicone. Furthermore, as shown in FIG. 2a, the bag body 1 is sandwiched between two identical or different polymer film, such as a polyethylene film and a polyimide film, with a foam interlayer 11, such as polyethylene. The foam interlayer is used to reduce the heat exchange between the cold and hot pack and the outside, and to prolong the temperature maintenance time. Wherein, the foam interlayer 11 can be selected from high molecular weight such as neoprene, polyurethane (PU) or polystyrene (Polystyrene). Compound.

In addition, as shown in FIG. 2b, the surface of the bag body 1 can be additionally attached to a fabric 12 to The texture and beauty of the bag body 1 are increased.

The contents 2 are loaded into the bag body 1, and the contents 2 include the first component of water absorption. The high molecular polymer is combined with the water of the second component to form an almost no-flow heat storage material 3 as a medium for heat absorption and heat dissipation; and a plurality of particulate load-bearing units 4 having at least one bearing space 41.

Since the water absorbing polymer has a high water absorption force, the type of the heat storage material 3 The state varies with the ratio of the water-absorbing polymer contained, for example, the first component of the water-absorbing polymer has a first weight, the water of the second component has a second weight, and the first Preferably, one weight is from 3% to 15% of the sum of the first weight and the second weight. The heat storage material 3 such as a fluid containing 1% by weight of a water-absorbing polymer generally has fluidity; and the heat storage material 3 containing 3% by weight of a water-absorbing polymer exhibits a fluid-free mass. Appearance; the heat storage material 3 containing 6% by weight of the water-absorbing polymer exhibits a fluid-free granular appearance to form a plurality of heat storage units 3'. When the proportion of the water-absorbing polymer of the first component exceeds 15% by weight, the water content (second component) of the heat storage material 3 is also relatively reduced, which inevitably lowers the heat storage material 3 or the heat storage units. 3' as a medium function of heat absorption and heat dissipation, so the first component of the water-absorbing polymer (first weight) ratio accounts for 5% of the total weight of the heat storage material 3 or the heat storage unit 3' to 12% is the best.

Furthermore, if the amount of ions contained in the water is more, the water absorption of the water-absorbing polymer The lower the force, the lower the ratio of the water-absorbing polymer can be appropriately reduced by using pure water. Wherein, the water-absorbing polymer is selected from the group consisting of, for example, polyacrylates, copolymerization of vinyl alcohol and acrylate Mainly modified or modified polyvinyl alcohol.

It is well known that the transfer of energy includes convection, conduction and radiation. The heat storage material 3 or the heat storage unit 3' can substantially reduce the energy movement caused by the heat convection, and the addition of the granular load-bearing unit 4 having the bearing space 41 can further block the heat convection and simultaneously hinder the occurrence of heat conduction. It is possible to extend the time of cold and hot application of the hot and cold pack. In other words, the cold and hot compress bag can provide colder or longer heat, and can achieve mild cold and hot application, in order to overcome the frostbite or burn of the skin caused by too severe temperature changes in the conventional hot and cold pack.

The carrying units 4 are selected from high molecular polymers such as polyethylene (PE), poly Urethane (PU), polypropylene (PP), acrylonitrile-butadiene-styrene copolymer (ABS), polyethylene terephthalate (PET) or polyamine (PA) or silicone (Silicon) The polymer polymer is prepared by mixing a far-infrared emitting material such as zirconia, tantalum or bamboo charcoal. Each of the carrying units 4 has at least one carrying space 41. As shown in FIG. 3a and FIG. 3b, the carrying unit 4 is, for example but not limited to, a tubular or hollow spherical shape, since the carrying unit 4 is of a material having a relatively high hardness, such as Xiao. The hardness (Shore A) is 85 A or more. Therefore, when the load bearing unit 4 is pressed by an external force, such as atmospheric pressure or pressure-type tension, the heat storage material is made by having appropriate supporting force and elasticity. 3 or the amount of the heat storage unit 3' removed from the bearing space 41 of the carrying unit 4 is very small, so that the cold and hot bag can remain slack and soft under the use state, so that the body shape can be closely matched and the most Good cold and hot effect.

Furthermore, each of the carrying units 4 is a thin-shell-shaped object, and the bearing space 41 accounts for each volume. The volume of the carrying unit 4 is at least 65% or more, so that the carrying units 4 can accommodate more heat storage materials 3 or the heat storage units 3 ′, so that most of the heat storage materials 3 or the heat storage units 3 ′ The thermal convection and heat conduction are effectively limited to the bearing space 41 of the carrying unit 4 without affecting the bag body. 1 volume. For example, the tubular load-bearing unit 4 having a diameter of 6 mm and a wall thickness of 0.2 mm has a bearing space 41 of about 87% of the volume of the tubular load-bearing unit 4; and a tubular load-bearing unit 4 having a diameter of 3 mm and a wall thickness of 0.2 mm, which has a bearing space. 41 occupies approximately 75% of the volume of the tubular carrier unit 4.

In practice, the content 2 includes 100 ml of heat storage material 3 or the heat storage. The unit 3' is added to the same volume of 100 ml of the carrying unit 4, and if the carrying space 41 is 87% of the volume of each carrying unit 4, after being uniformly stirred and vacuumed, the carrying unit 4 carries about 87 ml of the load. The heat storage material 3 or the heat storage units 3', while about 13 ml of the heat storage material 3 or the heat storage units 3' remain outside the load bearing units 4 to form a lubricating layer, and the contents 2 The volume is about 113ml. The ratio of the heat storage material 3 or the heat storage units 3 ′ to the load bearing units 4 may be determined by the support force, but the volume of the heat storage material 3 or the heat storage units 3 ′ is Compared with the volume of the load bearing unit 4, it can have both shaping and lubrication functions.

The bag body 1 must be subjected to a vacuum process to seal the bag body. 1. The purpose of the vacuuming procedure is to exclude most of the air in the bag body 1 so that the inside of the bag body 1 exhibits a low negative pressure, and the vacuum is basically controlled for a length of time, as long as the content 2 is not obtained. It is free to move inside the bag body 1. If the vacuum is excessive, the pressure difference between the inside and the outside of the bag body 1 is too large, so that the contents 2 are pressed by the excessively collapsed bag body 1 and cannot be moved, and the shaping function cannot be achieved.

The inside of the bag body 1 exhibits a low negative pressure, and appears to be compressed by atmospheric pressure. The appearance of the trap, but the load bearing unit 4 has a supporting force against the pressure difference between the inside and the outside of the bag body 1, and thus can accommodate the majority of the heat storage material 3 or the load of the heat storage units 3' on the load bearing units 4. In the space 41, the shaping function is achieved, and the remaining portion of the heat storage material 3 or the heat storage units 3' are left in the external gap of the carrying units 4 to achieve the lubricating function.

As shown in FIG. 4, most of the heat storage material 3 or the heat storage units 3' are It is limited to the bearing space 41 of the carrying unit 4, so that it is basically unable to move, so the heat convection and heat conduction with the outside is very small, so the temperature maintenance time becomes long. And the remaining part of the heat storage material 3 or the heat storage unit 3' provides a lubricating function, so that the heat storage material 3 or the heat storage unit 3' in the load bearing unit 4 and its bearing space 41 can be together The bag body 1 is moved by kneading to achieve a shaping function.

The production preparation procedure of the content 2 is as follows: first, the water-absorbing polymer is polymerized. The material is poured into the water according to the above ratio, and is uniformly stirred to form the heat storage material 3 or the heat storage units 3'; then, an appropriate amount of the plurality of load-bearing units 4 is further added, and the mixture is uniformly stirred again. In order to keep the cold and hot bag under the freezing point, the preparation process can be carried out by first mixing an appropriate proportion of the antifreezing agent with water. The antifreeze agent is mainly alcohol, such as propylene glycol, but not limited thereto.

Furthermore, the addition of an appropriate amount of preservative will contribute to the preservation of the contents 2, and The preservative is selected from the group consisting of salicylic acid, Benzoic acid, and the like, but is not limited thereto.

As shown in Figure 5, the bag is adjusted to fit the rear heel of the human body. The content 2 is substantially only between 15% and 60% of the volume of the bag body 1, so that the bag body 1 is flat to facilitate bending; if the volume of the content 2 is more than If the bag body 1 is 60% of the volume, the bag body 1 will be too fat due to the shape, and it will be difficult to bend, and there is no excess volume to move the contents 2, so that the shaping function cannot be achieved. Therefore, the larger the bag body 1 is, the lower the volume ratio of the content 2 is, because the heat storage material 3 or the heat storage units 3 ′ are substantially fluid-free, and the majority of the heat storage material 3 or The heat storage units 3' are confined in the bearing space 41 of the carrying units 4, so that they do not move or flow, so they are easy to be filled, and there is no liquid with vacuum. The air is removed together, so that the bag mouth of the bag body 1 is not contaminated, so that the sealing quality is not affected. Therefore, the hot and cold bag made according to the technical features of the present invention can be extruded and shaped, but does not bulge and harden, and can be pressed and tied to the body, and can help the sprain of the compression treatment and achieve the best. Cold and hot effect.

Therefore, through the implementation of this case, the effect of the gain is that the hot and cold bag Combining a water-absorbing high-molecular polymer of a suitable first component concentration with water of a second component to form a heat storage material or a plurality of heat storage units that are hardly flowing, and then storing the heat storage material or the heat storage unit The appropriate amount of the carrying unit 4 with the bearing space is combined, and the bag body is subjected to a vacuuming process, thereby facilitating shaping, prolonging the temperature maintaining time, not bulging when the bag body is pressed, and alleviating the heat absorption and heat release rate of the human body and The contents do not sag and other functions, in order to completely overcome the conventional cold and hot compress bag can not be stably supported, shaped but no support, the bag body bulges when the bandage is tied, the temperature maintenance time is too short, the human body heat absorption and heat release is too intense, seal The edge is easy to burst and the contents will sag.

Furthermore, the heat storage material or the heat storage units mostly follow the carrier list The bag can be shaped by pushing the carrying units in the moving bag to completely conform to any part of the body, so that the best cold or hot compress effect can be achieved.

In addition, since the majority of the heat storage materials or the heat storage units are housed in the In the carrying space of the carrying unit, the carrying unit can block the heat convection and heat conduction of the heat storage material or the heat storage unit, and can slow the movement of the heat storage material or the energy of the heat storage unit, so that the cold load can be greatly extended. Or hot time.

Especially in advance, this case has a stable support ability, in addition to being used as an anti-acne bed Pads, hot and cold pads, insulation pads, water beds and mouse pads can be used as mattresses in summer to sleep, instead of air-conditioning, in addition to environmental protection sources, but also to maintain indoor air circulation, can be called hot and cold bags Production One of the major breakthroughs.

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.
