Description

  The present invention relates to a disposable body warmer which is inserted inside clothing (especially underwear) and directly attached to a human body part, for example, around both shoulders and neck, or attached inside clothing (particularly underwear).

  Some conventional disposable warmers have compartments that divide the inside of the bag into multiple compartments, restrict the amount of heat generated so that the heating element in the bag does not move significantly, and improve flexibility and wrapping. Has been proposed.

  The disposable body warmer shown in Patent Document 1 is partitioned by a plurality of column seals and row seals, and a perforated cut line is provided at the center of the seal width of the partition seal, and is manually cut from the perforated cut line. Then, the size is such that it has a plurality of compartments in a row, and it can be attached because it is deformed and closely adheres to the shoulder, arm, neck, foot, and the like.

JP 2000-288008 A

  However, the disposable body warmer of Patent Document 1 is attached to clothing (especially underwear) corresponding to both shoulders and the neck, and is inserted inside the clothing (especially underwear) and immediately around both shoulders and neck. It is not affixed or affixed to the inside of clothing (especially underwear), and the heat generation temperature is set to be higher than that of direct affixing. Even if the exothermic temperature is lowered for direct application, the separator (release paper) is peeled off and inserted inside the clothing (especially underwear) and stuck around both shoulders and neck or the clothing (especially underwear) When trying to stick to the inner surface, the weak adhesive coating formed on the disposable warmer body before inserting the disposable warmer body into place will be in close contact with the inner surface of the skin or clothing (especially underwear). In many cases, it is difficult to insert the main body into a predetermined position.

  The present invention has been devised in view of the above-described points, and the object of the present invention is to insert a disposable hand warmer from the outside of the garment with one hand by inserting it at a position where the hand can reach between the human body part and the garment. Is to provide a disposable body warmer that can hold and hold the separator with the other hand.

  In order to solve the above problems, the disposable body warmer of the present invention has a heating element enclosed in a bag body, and has an adhesive coating on one outer surface of the bag, and is adhered to a human body part or clothing by the adhesive coating. A disposable body warmer body and a separator in which the sheet material is folded in half, and one outer surface of the half-folded sheet material is laminated on the pressure-sensitive adhesive coating film and adhered to one outer surface of the bag body. It is characterized by that.

  According to this configuration, the disposable body warmer in a state where the separator is not peeled is applied to a portion where a human body or clothing is to be attached, and in that case, the direction in which the separator is peeled is determined, and the folded end of the separator becomes the peeling start end. Like that. Then, when the half edge (on the side opposite to the folded end) of the separator that is not attached to the disposable body body of the separator is pulled, the separator starts to peel so as to turn 180 ° from the folded end. As the separator is peeled off, the adhesive coating coated on the disposable body warmer gradually increases the exposed area and opposes the human body part or clothing. If the force which presses a disposable body warmer main body is strengthened, this disposable body warmer body can be stuck to a human body part or clothes.

  In the invention having the above-described configuration, it is preferable that the separator is formed by half-folding the sheet material and bringing the overlapping surfaces into close contact with each other by a peelable adhesive means. With this configuration, since the separator does not open at the manufacturing stage, it is easy to individually package the disposable body warmers. At the time of use, after separating the overlapping surface of the sheet material in advance, the separator is half-folded and the overlapping surface is peeled and developed, and then the separator is applied to a human body part or clothing and is separated.

In the invention having the above-described configuration, the disposable body body has a long shape corresponding to both shoulders and the circumference of the neck, and has the adhesive coating film on the left and right portions of one outer surface of the bag body, and the separator includes the adhesive It is preferable that the left and right pair are provided so as to cover the agent coating film. In the case of this configuration, it is attached as follows.
First, the outer half surface portion of the separator is set to be in close contact with the skin and the edge of the outer half surface portion is the upper end, and the disposable body warmer is inserted into the clothing (especially underwear). To apply directly, insert the separator on the skin side and the disposable warmer body as the clothing (especially underwear) side, and to apply it on the clothing (especially the underwear), place the separator on the clothing (especially the underwear) side and the disposable body warmer body. Insert as skin side. Since the separator covers the weak adhesive film formed on the disposable warmer body, the weak adhesive film does not adhere to the skin or clothing (especially underwear) during insertion. Can be smoothly inserted into a predetermined position. When the disposable body warmer is inserted into positions corresponding to both shoulders and around the neck, in that state, the area corresponding to the back of the neck of the disposable body warmer is pressed with one hand. Next, with the other hand, the edge of the separator is picked and pulled, so that the folded end of the separator is peeled off so that the angle is 180 °. Next, it can be weakly adhered to the skin through the weak adhesive coating film exposed by the peeling of the separator, and the separator can be peeled off in the same way to weakly adhere to the skin through the weak adhesive coating film. Thereby, the disposable body warmer body can be directly pasted around both shoulders and the neck, or it can be pasted on clothes (especially underwear).
If comprised in this way, it can insert smoothly into the position corresponding to the both shoulders and neck circumference inside clothing (especially underwear), and it sticks directly to both shoulders and neck circumference, or it sticks on the inner surface of clothing (especially underwear). Disposable body warmers for both shoulders and neck can be provided that can be worn well by one person.

  According to the present invention, since the separator can be peeled off so that the separator is turned 180 ° from the folded end, the disposable body warmer in a state where the separator is not peeled is applied to the human body part or the part to which the clothes are to be applied and pressed from the outside of the clothes. Until this time, the separator can be easily peeled off and the disposable body body can be attached to a human body part or clothing. Therefore, in particular, it can be inserted in a position where the bare hand between the human body part and the clothing can reach, hold the disposable body warmer from the outside of the clothing with one hand, and peel the separator with the other hand, It is convenient in that the disposable body body can be attached to a position where the bare hand between the body part and clothing can be reached by one person.

  Hereinafter, a disposable body warmer according to an embodiment of the present invention will be described with reference to the drawings.

[First Embodiment]
As shown in FIG. 1, the disposable body warmer 1 of this embodiment includes an elongated disposable body warmer body 10 corresponding to both shoulders and around the neck, and left and right hands corresponding to both shoulders of one surface portion of the disposable body warmer body 10. It has the separators 20 and 20 stuck to the position so that peeling is possible.

  As shown in FIG. 2, the weak adhesive coating films 30 and 30 are provided in the position where the separators 20 and 20 of the disposable warmer main body 10 are affixed. The separator 20 is adhered in such a manner that it can be folded and peeled in half, covers the weak pressure-sensitive adhesive coating 30, and the folded-back end 20c faces downward when the disposable body 10 is used. Yes. The weak adhesive coating film 30 can be, for example, a weak adhesive hot melt coating film.

As shown in FIG. 1, a disposable body warmer body 10 is formed by enclosing a heating element 12 that generates oxidation heat in the presence of air in a flat bag body 11 having air permeability. The bag body 11 has an elongated shape corresponding to both shoulders and around the neck, the center upper edge 11a is a concave arc shape corresponding to the neck, both side upper corners 11b are formed in the corners of a small arc, Both edge portions 11c are formed in the corners of a large arc. The bag body 11 has a flat shape in which the inner space of the bag body is divided into three sections corresponding to both the shoulder and the neck by a heat seal S, and a heating element 12 is enclosed in each of the three sections.
The form and composition of the heating element 12 is a heating composition mainly composed of metal powder such as iron powder that generates heat by oxidation in the presence of air, but is not particularly limited. The heating element 12 generally includes iron powder, activated carbon, salts, a water-absorbing resin, and water, or mainly contains metal powder such as iron powder, salts, water, activated carbon, and a water retention agent. The iron powder that generates heat by oxidation in the presence of air includes, for example, raw material iron powder for a composition that mixes with a reaction aid, water, and a water retention agent and generates heat slowly in the atmosphere.

  The bag body 11 is sufficient if at least one surface portion has air permeability. Since the weak pressure-sensitive adhesive coating film 30 is formed on the surface portion including the separator 20 of the bag body 11, it is preferable that the at least one surface portion is a surface portion on which the weak pressure-sensitive adhesive coating film 30 is not formed. For example, the surface portion 11d of the bag body 11 on the side not provided with the separator 20 has an outer layer made of a non-woven fabric and an inner layer made of an air permeable sealant film (polyethylene film) and has a pierced hole to make it air permeable. In order to make the surface portion 11e on the side provided with a surface property suitable for the formation of a weak pressure-sensitive adhesive coating film, the surface portion 11e has a single layer sealant film (polyethylene film) or an air permeability composed of a sealant film (polyethylene film). It can be composed of laminated films that do not.

  As a specific configuration example of the surface portion 11e on the side of the bag body 11 including the separator 20, a polyethylene uniaxially stretched film (white) containing inorganic filler, low density polyethylene (LDPE), and linear low density polyethylene (LLDPE) A three-layer coextruded film having no air permeability can be used.

  The separator 20 is a slightly sticky hot coated and formed in the middle of one half surface portion (half surface portion having a short dimension a) 20a of a pair of half surface portions that overlap each other by folding a sheet (for example, paper) in half. The melt coating film 21 and the release agent coating film 22 formed on the other half surface portion (half surface portion of the long dimension b) 20b are brought into close contact with each other and maintain easy peeling and adhesion. In addition, it can replace with the slightly adhesive coating film 21, and can maintain easy peelability and an adhesive state also by carrying out an easy peel and carrying out a weak heat seal.

  In the separator 20, the release agent coating film 23 formed on the outer surface of the outer half surface portion (the outer surface of the half surface portion 20 a having a short dimension “a”) overlaps the weak adhesive coating film 30 formed on the bag body 11. Thus, the separator 20 is adhered to the bag body 11 in an easily peelable and bonded state.

  The separator 20 is adhered to the bag body 11 so that the folded back end 20c is on the lower end side when the disposable body 10 is used, and the bag body is cut by a press or the like in a folded state. 11 has an arcuate contour side 20 d corresponding to the corner of the large arc on both side portions 11 c of the lower edge 11, so that it does not protrude from the bag body 11.

  Separator 20 has an advantageous configuration for ensuring easy peelability when deployed, and the adhesion area between slightly adhesive hot-melt coating film 21 and release agent coating film 22 is not an entire surface. The half-folded sheet (paper) has a partial portion that does not reach the edge of one half surface portion and the edge of the other half surface portion. Separator 20 is a slightly folded hot paper that is slightly sticky than the edge of one half surface (half surface portion of short dimension a) 20a of a folded sheet (paper) on which a slightly adhesive hot melt coating film 21 is formed. The other half surface portion (long surface b half surface portion) 20b on which the melt coating film 21 is formed is overlaid in an extended state, and the other half surface portion can be picked and unfolded. Since it has releasability, it can be easily deployed.

  According to the disposable body warmer 1 of the above embodiment, since the separator 20 attached to one surface of the disposable body body 10 is in a state of folding the sheet material in a folded state before use, the individual packaging is not performed. This is a suitable form.

  For direct attachment, the separator 20 is inserted on the skin side and the disposable body warmer body 10 is inserted on the clothing (especially underwear) side. The body 10 is inserted as the skin side. As shown in FIGS. 4A and 4B, since the separator 20 covers the weak adhesive coating film 30 formed on the disposable body warmer body 10, the weak adhesive coating film 30 is inserted into the skin or during the insertion. It can avoid sticking to the inner surface of clothing (especially underwear) and can be smoothly inserted into the inside of clothing (especially underwear) corresponding to both shoulders and around the neck.

  Next, the disposable body warmer 1 is put on both shoulders and around the neck, and in this state, the area corresponding to the neck rear surface of the disposable body body 10 is pressed with the hand opposite to the separator 20 to be peeled off. Next, with the hand on the same side as one separator 20 to be peeled off, the edge of the separator 20 is picked and pulled, so that the folded end of the separator 20 is peeled so as to be turned 180 °. . Next, the skin or clothing (especially underwear) can be weakly adhered through the weak adhesive coating film 30 exposed by the separation of the separator 20, and the separator 20 is similarly peeled off to form the weak adhesive. It can weakly adhere to the skin or clothing (especially underwear) through the coating film 30. Thereby, the disposable body warmer body 10 can be attached to both shoulders and around the neck.

  Further, according to the disposable body warmer 1 of the above-described embodiment, the separator 20 includes an end edge of one half surface portion (half surface portion having a short dimension a) 20a and an end portion of the other half surface portion (half surface portion having a long dimension b) 20a. Since the edges do not coincide with each other and do not overlap, it is easy to pick the edge of the other half surface portion 20a, so that the edge of the other half surface portion 20a of the separator 20 is placed with the disposable body warmer body 10 applied to both shoulders and around the neck. It can be easily picked and pulled, the separator 20 can be easily peeled off, and the disposable body warmer body 10 can be easily stuck around both shoulders and the neck.

  Furthermore, according to the disposable body warmer 1 of the above-described embodiment, the disposable body body 10 has the interior space of the bag body 11 divided into three in the shoulder width direction by heat sealing, and the heating element 12 is enclosed in each space, and Since the upper edge 11a of the central portion of the bag body 11 has a concave arc shape corresponding to the circumference of the neck, the uneven movement of the heating element 12 is restricted inside the bag body 11, and the heat generation is made uniform as a whole. If the center part of the upper edge of the body 11 is located around the neck, both side portions can be attached not on the back but on both shoulders.
