Description

[Detailed explanation of the idea] The present invention relates to the improvement of so-called disposable body warmers.

A so-called disposable bag that is filled with iron powder, oxidation accelerators such as food temperature, fillers such as activated carbon and wood chips used as water retention hardening inhibitors, and water, and shaken or kneaded to cause an oxidation reaction and generate heat. Conventionally, warmers have a flat shape and must be carried in a pocket or wrapped around a cloth or a belt to secure them, which has the drawback of limiting the scope of their use.
On the other hand, a disposable body warmer is known from Japanese Utility Model Application Publication No. 57-126221, which has an adhesive surface applied to the edge of the bag so that it can be fixed anywhere. In the case of the publicly known example,
Since the adhesive adheres to the object to which it is attached, the residue after removing the disposable body warmer tends to be sticky or dirty, and if the adhesive is too weak, the disposable body warmer may fall off even when a slight external force is applied. On the other hand, if the adhesive is too strong, there is a risk that it will be difficult to peel off the disposable body warmer, or that part of the surface of the adhered article will be peeled off and damaged when it is peeled off. The present invention aims to provide a disposable body warmer that solves these problems.

The present invention is intended to achieve the above-mentioned purpose, and is made by cutting the bag into the desired length by cutting it off at both ends of the bag, which contains oxidation accelerators such as iron powder and salt, filler materials such as activated carbon and wood chips, and water. It is characterized by having a cut line that is shaped like a string.

In the illustrated embodiment, cut lines (so-called perforations) 3 extending from the edge to the vicinity of the opposite edge are alternately formed on the ears 2, 2' at both ends of the bag body 1. They are arranged parallel to each other at intervals. Therefore, by cutting along the cut line 3, each of the ears 2, 2' can be made into a single string as shown in FIG. 2, and the strings 4, 4' on both sides By tying together the disposable body warmers can be attached to various articles.

The disposable body warmer of the present invention has a much wider range of use than conventional disposable body warmers as follows. First of all, it can be used for human body heating, such as on the back, where clothing normally does not have pockets. It can also be used to insulate and heat pots that store food. For example, when an infant goes out, it has until now been necessary to fill a thermos pot with hot water and carry it around, but if you fill a milk bottle with hot water and fix the disposable body warmer of this invention to the outer periphery of the bottle, you can keep it warm. You can make warm milk anytime without having to carry a pot. Also, you can enjoy hot sake by fixing it to a pack of sake, etc., while traveling in a car or the like. As described above, the present invention is convenient in that it can be attached to any article to be attached, and there is no need for special fasteners such as cloth or belts, which is required when attaching conventional products. Furthermore, unlike the above-mentioned known example in which an adhesive surface is provided, there is no problem caused by the adhesive adhering to the article to be adhered, and the adhesive is too weak and may fall off due to some external force, or the adhesive may fall off due to some external force. The above object is achieved by eliminating the fear that the adhesive will be too strong and difficult to peel off, or that part of the surface of the adhered article will be peeled off and damaged at the same time when it is peeled off.
