Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ice pillow filled with a cooling agent inside a bag, and even when the pillow is used, the cooling agent inside the bag extends around the bag due to the weight of a human head. An object of the present invention is to provide an ice pillow that fits the shape of a human head without flowing.

2. Description of the Related Art Generally, an ice pillow is used when it is desired to cool an affected part due to fever, headache, toothache, bruise, etc., or when it is hot and difficult to sleep in summertime. Has been widely used recently. This ice pillow can be cooled easily in a freezer, but if it is put in a freezer, it will not only cool to the required temperature but also solidify and become hard and painful. In order not to give a sense of incongruity, a towel, a cloth, etc. were wrapped around the ice pillow before use. However, wrapping a towel, cloth, etc. on an ice pillow when using it is too troublesome,
In order to eliminate this drawback, an ice pillow has recently been proposed in which a gel that does not freeze even when cooled in a freezer can be used so that the head can be placed directly on the ice pillow.

[0003]

However, since the above-mentioned ice pillow uses an antifreeze as a cooling agent, when the inside of the bag is filled with a cooling agent, the liquid fills the entire bag and swells. When he put his head in the center of the bag, the cooling agent that was under the head, depending on the weight of the head, the thinner layer of the bag at the center of the head to escape to the periphery of the bag, A new disadvantage arises in that it lacks the function of a pillow.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention comprises a bag body provided with a storage room for filling a cooling agent therein, and the storage room is completely contained in the storage room. An object of the present invention is to provide a partition device for an ice pillow containing a cooling agent, wherein a partition is provided in a non-partitioned state. Also,
An object of the present invention is to provide an ice pillow bulkhead device filled with a cold insulator, wherein the cold insulator is an antifreeze and the bulkhead is provided corresponding to the shape of a human head. It is another object of the present invention to provide an ice pillow partition device filled with a cooling agent in which the lower edge of the bag body is formed in a curved shape.

According to the present invention, the antifreeze cooling agent filled in the storage compartment of the bag is filled with the partition wall provided in the storage compartment so that the cooling agent does not flow around even when the human head is placed in the bag. Because the pillow stays at the swelling and expands, a pillow that fits the human head can be obtained.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a plan view of the present invention, and FIG. 2 is a vertical sectional view taken along line AA of the present invention. (1) is a bag made of a flexible material constituting a pillow, and the bag (1) is formed of a front member (2) and a back member (3). The front member (2) and the back member (3) are made of a three-layer synthetic resin film. For example, an LLD polyethylene film, a barrier nylon film for an alcohol barrier, and a polyolefin-based polypropylene are polymerized and formed from the inside of the bag (1).

The external dimensions of the bag (1) are 250 mm (width)
X 185 mm (depth) x 25 mm (height), and the inside of the bag (1) forms a storage chamber (4) for filling with a cooling agent. The storage chamber (4) is provided with a partition (5) by bonding the front surface member (2) and the back surface member (3) of the bag body (1). As shown in FIG. 1, the partition (5) does not completely partition the storage chamber (4), but has a gap from the upper edge (6) and the lower edge (7) of the bag body (1). It is provided substantially from the upper edge (6). In addition, the upper end (8) of the partition (5) is provided so as to draw a curve toward the center, and the head rest (9) is provided in the partition (5).
To form

In the interior of the storage room (4), a cooling agent (10)
Is filled. The cooling agent (10) is an antifreeze that does not solidify even when cooled in a freezer.
It is produced by adsorbing ethanol (41%) and water (56%).

The lower edge (7) of the bag (1) is formed in a curved shape, so that the neck is not particularly cooled during use.

However, in order to fill the storage chamber (4) in the bag (1) with the cooling agent (10), the cooling agent (10) is to be filled from one place of the upper edge (6) of the bag (1). ) Is injected, and then the injection port is subjected to heat fusion or ultrasonic fusion. Then
As shown in FIG. 2, the coolant (10) is uniformly filled in the storage chamber (4) by the partition walls (5) of the storage chamber (4).

FIG. 3 shows a use state of the present invention. When a human head is placed on a head mounting portion (9) formed on a bag (1), the head mounting portion (9) is directly below the head mounting portion (9). Storage room (4) for bag (1)
Since the cooling agent (10) filled in the storage chamber (4) does not flow to the other storage chamber (4) by the partition wall (5), the swelling of the storage chamber (4) is maintained as it is, and as a result, the shape of the head is reduced. Fits well and provides cushioning.

Although the basic mode of the present invention has been described above, the present invention is not necessarily limited to only the above-described embodiment, but has the above-mentioned constitutional requirements of the present invention and the present invention. The present invention achieves the object and can be appropriately modified and implemented within a range having the following effects.

[0013]

According to the ice pillow bulkhead device filled with the cooling agent according to the present invention, the partition wall is provided in the bag housing room, so that the cooling agent in the bag housing room flows to the outer periphery of the bag body. Instead, it stays on the partition in the storage room, so the storage room directly below the head rest is bulged, especially when a human head is placed, so it fits the shape of the head and provides cushioning. As a result, the cooling effect can be surely enhanced, so that the pillow has an optimum effect.
