Description

  The present invention relates to a disposable body warmer that easily fits the body.

  Conventionally, a disposable body warmer has a heat generating composition that generates heat in the presence of air, for example, a heat generating composition made of iron powder, inorganic salt, activated carbon, water, etc., and has a nonwoven fabric made of, for example, a thermoplastic synthetic fiber and a vent hole. What is stored in a bag comprising a surface layer laminated with a non-breathable resin film and a back layer laminated with a non-porous non-breathable resin film and a non-woven fabric is known (Japanese Patent Publication No. 57-14814). . The disposable body warmer has a palm-like, generally rectangular shape, and is usually manufactured by superimposing the surface layer and the back surface layer, placing the exothermic composition therebetween, and further thermally bonding the outer periphery thereof. In order to avoid contact with air when not in use, the disposable body warmer is hermetically stored in a bag made of a non-breathable resin film, and is taken out of the bag and used in contact with the exothermic composition when in use. As a result, the exothermic composition and air are reacted to generate heat.

  The disposable body warmer immediately starts to generate heat when taken out from the airtight bag or container, and can maintain a predetermined temperature for a long time. Therefore, the disposable body warmer is used as a hand warmer for warming various parts of the body. Yes. Recently, there is an increasing demand for thermal medical use not only for hands and feet but also for hot compresses such as the neck and waist.

Japanese Utility Model Publication No. 57-14814

However, in the conventional disposable body warmer, since it has a substantially palm-like rectangular shape, it is necessary to surround and warm the front and back sides of the body from the circumferential direction, that is, around the hand (palm and back of the hand), torso Around the body, around the waist, around the neck, around the forearm, around the upper arm, around the thigh, around the lower leg, around the ankle, or around the foot (ankle and sole) from the circumferential direction It was difficult to fit when it was desired to surround and warm up.
Specifically, when it is desired to surround and warm the circumference of the hand from the circumferential direction, a disposable hand warmer gripped by the left and right hands is used, and while warming the palm of one hand by the hand warmer held by one hand, the other hand The warmer must be warmed by pressing the disposable hand warmer held by one hand against the back of the other hand. In this case, it is possible to warm only one hand (one hand), that is, the palm of one hand and the back of the hand using both hands, and cannot efficiently warm by surrounding the left and right hands from the circumferential direction.

  Disposable body warmers can also be used on other parts of the body: around the torso, around the waist, around the neck, around the forearm, around the upper arm, around the thigh, around the lower leg, around the ankle, or around the foot. Since it is difficult to fit in the surroundings (the back of the foot and the sole), the specific part of the body cannot be surrounded from the circumferential direction and heated efficiently.

  The present invention has been made in view of such points, and the object of the present invention is to dispose of a disposable body warmer that fits a specific part of the body and surrounds the specific part of the body from the circumferential direction to efficiently warm the body. Is to provide.

In order to achieve the above object, in the present invention, a heat generating composition that generates heat in the presence of air is stored in a breathable composite structure in which a thermoplastic synthetic resin film is laminated on a nonwoven fabric made of thermoplastic synthetic fibers. A disposable body warmer is assumed. And the said composite structure is formed in cyclic | annular form or strip | belt shape so that it may fit in the specific site | part of a body, It is characterized by the above-mentioned.
Because of this specific matter, the composite structure is formed in a ring or band, so if you want to warm around a specific part of the body, for example around the hand, you can fit the hand by wrapping the composite structure around the palm and back of the hand. The exothermic composition housed therein heats one palm and the back of the hand without using the other hand, enabling efficient heating around the left and right hands.
Moreover, body identification around the torso, around the waist, around the neck, around the forearm, around the upper arm, around the thigh, around the lower leg, around the ankle, or around the foot (ankle and sole) The specific structure of the body can be efficiently warmed by the exothermic composition that fits the specific part by winding the composite structure around the part and is housed in the specific part.

Moreover, it is preferable that the said composite structure is divided into several storage chambers so that the said heat-generating composition may be separately accommodated in the circumferential direction.
In this case, the exothermic composition is restricted from being displaced in the circumferential direction, and the exothermic composition is uniformly heated in the circumferential direction of the composite structure, so that it is not only around the hand such as the palm and the back of the hand, Specific parts of the body such as around, around the waist, around the neck, around the forearm, around the upper arm, around the thigh, around the lower leg, around the ankle, or around the foot (ankle and sole) It can be warmed evenly by surrounding from the circumferential direction.

  In short, by forming the composite structure in an annular shape or a belt shape, the composite structure can be wound around and fitted to a specific part of the body such as the palm and the back of the hand, and the specific part can be efficiently heated.

It is a perspective view of the disposable body warmer concerning the present invention. It is a perspective view which shows the state which fitted the disposable body warmer of FIG. 1 around the hand.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings for understanding of the present invention. The following embodiment is an example embodying the present invention, and is not intended to limit the technical scope of the present invention.

  In FIG. 1, reference numeral 1 denotes a disposable body warmer according to an embodiment of the present invention. This disposable body warmer 1 generates heat in the presence of air (not shown), for example, iron powder, inorganic salt, activated carbon, water, and the like. A surface layer obtained by laminating a heat-generating composition (not shown), for example, a nonwoven fabric made of a thermoplastic synthetic fiber such as polytrimethylene terephthalate fiber and a non-breathable resin film having vent holes, and a non-porous non-breathable resin film And a back surface layer laminated with a non-woven fabric. And the said disposable body warmer 1 is normally manufactured by superposing | stacking the said surface layer and a back surface layer, putting a heat-generating composition in the middle, and also heat-bonding the outer periphery. In order to avoid contact with air when not in use, the disposable body warmer 1 is hermetically housed in a bag made of a non-breathable resin film. As a result, the exothermic composition and air are reacted to generate heat.

  The disposable body warmer 1 starts to generate heat immediately after being taken out of the airtight bag or container, and can maintain a predetermined temperature for a long time. For this reason, the disposable body warmer 1 is used for heat insulation of various parts of the body, and recently, for thermal medical use, palms and back of the hand (around the hand), around the trunk, around the waist, around the neck, around the forearm. It is also used for a hot compress around a specific part of the body such as around the upper arm, around the upper arm, around the thigh, around the lower leg, around the ankle, or around the foot (back of the foot and sole).

  As shown in FIG. 2, the bag 11 of the disposable body warmer 1 is formed in an annular shape so as to fit around the hand as a specific part of the body. In addition, the bag body 11 includes a storage chamber 12 corresponding to the palm side of the hand 2 so that the exothermic composition is stored in positions corresponding to the palm of the hand 2 and the back of the hand 2 in the circumferential direction. The storage room 13 corresponding to the back side of the hand 2 is divided into two. The bag body 11 is bound with the back side (inner surface) sides of the circumferential edges 12a and 13a of the storage chamber 12 on the palm side of the hand 2 and the storage chamber 13 on the back side of the hand 2 facing each other. Yes. In this case, both the storage chambers 12 and 13 are formed in a size of 150 mm × 100 mm, and the edge portions 12a and 13a are bound by using hot melt (not shown) or heat sealing.

  Therefore, in this embodiment, since the bag body 11 of the disposable body warmer 1 is formed in an annular shape, the bag body 11 is fitted around the palm of the hand 2 and the back of the hand 2 to fit around the hand 2, The exothermic composition housed inside allows the palm of one hand 2 and the back of hand 2 to be surrounded and warmed from the circumferential direction without using the other hand, so that the left and right hands 2 can be warmed efficiently. it can.

In addition, the bag 11 and the storage chamber 12 and the hand corresponding to the palm side of the hand 2 are stored so that the heat generating composition is stored at positions corresponding to the palm of the hand 2 and the back of the hand 2 in the circumferential direction. Since the compartment is divided into two storage chambers 13 corresponding to the second instep side, the exothermic composition is restricted from being offset in the circumferential direction. That is, the heat generating composition in the bag body 11 is restricted from moving toward the palm side of the hand 2 or the back side of the hand 2.
Thereby, the heat generating composition can generate heat uniformly in the circumferential direction of the bag body 11, and the palm of the hand 2 and the back of the hand 2 can be warmed evenly.

  In addition, this invention is not limited to the said embodiment, The other various modifications are included. For example, in the above-described embodiment, the bag 11 of the disposable body warmer 1 is wrapped around the hand 2 (the palm and the back of the hand) so as to surround it from the circumferential direction. Disposable body warmers around the body, around the forearm, around the upper arm, around the thigh, around the lower leg, around the ankle, or around the foot (back of the foot and sole) Needless to say, it may be wound so as to be surrounded. In this case, it is necessary to set the length of the bag body to a length according to the specific part of the body, and it is possible to efficiently warm the specific part of the body.

  Moreover, in the said embodiment, although the bag body 11 was divided into the two storage chambers 12 and 13 in the circumferential direction, you may be divided into the three or more storage chambers. In addition, the storage chamber may be partitioned so that the length of the bag set to a specific length of the body increases as the length of the bag increases. On the other hand, the bag body may be formed in an annular shape or a belt shape made of a single storage chamber.

  Moreover, in the said embodiment, although it bound with the back surface (inner surface) side of the edge parts 12a and 13a of the circumferential direction of both storage chambers 12 and 13 of the bag body 11 facing each other, both storage chambers of a bag body They may be bound in a state where the back surface and the front surface (outer surface) side of the edge in the circumferential direction face each other. An elastic material such as rubber that expands and contracts in the circumferential direction may be interposed between the circumferential edges of the two storage chambers of the bag body. In this case, the fitting performance with respect to the specific part of the body is remarkably improved and the deviation is eliminated, and the specific part of the body can be warmed more efficiently.

  Furthermore, in the said embodiment, although the bag body 11 of the disposable body warmer 1 was formed in cyclic | annular form, the bag body of a disposable body warmer may be formed in strip | belt shape. In that case, the end portion of the bag body may be locked with a hook-and-loop fastener, or may be surrounded and locked from the outside with a rubber band or the like.
