The present invention relates to a long-acting ice pack, and more particularly to a long-acting ice pack able to extend the time of cold preservation and provide an appropriate temperature for ice compress.
In many situations of our daily lives, there is a need for ice compress. Ice compress is one of cryotherapy, which is simple to practice, easy to obtain an ice pack, and has a good curative effect, etc. Therefore, within 24 hours after an acute injury, people often use an ice pack to reduce pain, inhibit an inflammation, contract blood vessels, reduce edema, reduce the metabolism, and achieve the purpose of the treatment of acute sports injuries.
In the early conventional ice compress method, ices are put in a plastic bag, and the ice bag is directly in contact with the user's skin for ice compress. In this way, the ices melt fast, so the effect of the ice bag is not good. An ice pack 1 is developed as shown in
Accordingly, the inventor of the present invention has devoted himself based on his many years of practical experiences to solve these problems.
The primary object of the present invention is to overcome the shortcomings of the prior art and to provide an ice pack. When in use, the initial temperature of the ice pack is appropriate, not too low, and the time of cold preservation is longer than the prior art. The ice pack can be used for ice compress for a long time, and its temperature is quite suitable for the human body.
In order to achieve the aforesaid object, the long-acting ice pack of the present invention comprises a mixture of a cold preservation substance and a gel therein. The gel is mixed with a plurality of heat-insulating particles. The heat-insulating particles can be used to block the transmission of the interior temperature of the ice pack and the outside temperature for a portion of the ice pack so as to decrease the area and efficiency of temperature transmission. The ice pack not only effectively extends the time of cold preservation, meeting the demand of ice compress or cold preservation for a long time, but also provides the most comfortable temperature for ice compress, without using a towel to cover the ice pack.
The ice pack comprises a body. The body comprises a cold preservation substance and a gel therein. The cold preservation substance may be one of methylcellulose and acrylic acid polymer, but not limited thereto. The gel may be a high water-absorbing molecular polymer, but not limited thereto. The cold preservation substance and the gel are disposed in a waterproof layer. The waterproof layer is covered with an outer covering layer. The feature of the present invention is that the gel is further mixed with a plurality of heat-insulating particles. The heat-insulating particles may be made of Styrofoam material and have a block shape, a strip shape, a sheet shape, or a spherical shape.
The mixing ratio of the heat-insulating particles can be increased or decreased as necessary. If the ratio is increased, the portion of the ice pack to block the transmission of the interior temperature of the ice pack and the outside temperature will be increased. On the contrary, if the mixing ratio of the heat-insulating particles is reduced, the portion of the ice pack to block the transmission of the interior temperature of the ice pack and the outside temperature will be decreased.
In order to understand the present invention, embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings.
As shown in
The mixing ratio of the heat-insulating particles 23 can be increased or decreased as necessary. If the ratio is increased, the portion of the ice pack for blocking the transmission of the interior temperature of the ice pack and the outside temperature will be increased. That is to say, the interior and exterior temperatures of the ice pack won't exchange easily. For the ice pack 2, the time of cold preservation time is prolonged, but the temperature sensed by the human body is relatively high during ice compress. On the contrary, if the mixing ratio of the heat-insulating particles 23 is reduced, the portion of the ice pack for blocking the transmission of the interior temperature of the ice pack and the outside temperature will be decreased. That is to say, the interior and exterior temperatures of the ice pack will exchange easily. For the ice pack 2, the time of cold preservation time will be shortened, but the temperature sensed by the human body will be relatively low during ice compress.
As shown in
Although particular embodiments of the present invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the present invention. Accordingly, the present invention is not to be limited except as by the appended claims.
