Description

本発明は、二重に包装された従来の使い捨てカイロに対して、特に、一重包装とするため、発熱材を充填する部屋と発熱させる部屋とに分けた2室式の使い捨てカイロ包装材に関するものである。   The present invention relates to a two-room disposable body warmer packaging material, which is divided into a room for heating material and a room for heat generation, in order to make a single-layer packaging, in contrast to the conventional disposable body warmer packaged twice. It is.

従来の使い捨てカイロは、紙や樹脂繊維或いは孔あき加工されたフィルム等で作成したカイロ包装袋に、炭、鉄粉、吸水性素材等の内容物を充填したカイロ本体と、それを外気から遮断して、発熱を防ぐための外袋との構成になっている。すなわち、内容物を充填したカイロ本体をバリア性を有する外袋にいれた二重包装形式で流通していることが知られている。   A conventional disposable body warmer is a body warmer made of paper, resin fiber, or perforated film, filled with contents such as charcoal, iron powder, water-absorbing material, etc., and shielded from outside air. And it is the structure with the outer bag for preventing heat generation. That is, it is known that the body of the warmer filled with the contents is distributed in a double packaging form in an outer bag having a barrier property.

この二重に包装された使い捨てカイロの使用方法は、外袋からカイロ本体をとりだすことにより、空気中の酸素と内容物が反応して発熱するようになっている。また、発熱を促進させるためにカイロ本体を手で揉む等をすることにより、内容物がよく混合されて薄く形成された本体の袋の繊維間等を通じての外気により一段と早く発熱するものである。   In the method of using the double-packed disposable body warmer, the body body is taken out from the outer bag so that oxygen in the air reacts with the contents to generate heat. Further, by manually holding the body of the warmer in order to promote heat generation, the contents are mixed well and heat is generated more quickly by the outside air between the fibers of the main body bag formed thinly.

しかしながら、従来の使い捨てカイロは本体の発熱を防ぐためのバリア性を有する外袋が必要である。しかし使用時にはこの外袋が不必要となり、ゴミとなってしまう。さらに、内袋(カイロ本体)と外袋と二重に包まれていることも包装材コストを上げる原因になっていた。   However, the conventional disposable body warmer requires an outer bag having a barrier property to prevent heat generation of the main body. However, this outer bag becomes unnecessary and becomes garbage when used. Furthermore, the double wrapping of the inner bag (the body of the warmer) and the outer bag has also caused the packaging material cost to increase.

そこで本発明は、上記の問題点を解決するためになされたもので、使い捨てカイロの包装形態を二重包装から一重包装にしても内容物が発熱しない形態とし、特に、表裏の樹脂フィルムにより内容物を充填する収納部とその片側或いは両側端部に空収納部を設け、この空収納部の裏面フィルムには内容物が漏れない程度の大きさの多数の微細孔を設けた2室式の使い捨てカイロ包装材を提供するものである。   Therefore, the present invention has been made to solve the above-described problems, and even if the packaging form of the disposable body warmer is changed from double packaging to single packaging, the contents do not generate heat. A two-chamber type in which a storage portion for filling an object and an empty storage portion are provided at one or both ends thereof, and a back film of the empty storage portion is provided with a large number of fine holes of a size that does not leak contents.

FIG. 3 is an explanatory cross-sectional view showing a state in which the isolated portion (weakly sealed portion) in the two-chamber disposable warmer packaging material showing an embodiment of the present invention is peeled off and the contents are partially moved to generate heat. .

図1に示すように、本発明における2室式の使い捨てカイロ包装材の構成は、適宜トレイ形状や袋形状等に形成された表面フィルムに炭、鉄粉、吸水性素材等の発熱体である内容物を充填した後、裏側を裏面フィルムで密封した2室式の使い捨てカイロ包装材であって、前記トレイ形状等の表面フィルム(11)を複数の収納室に隔絶区分けし、このいずれか一つの収納室(11a)に内容物(30)を充填し、この片側或いは両側に区分けされた空収納室(11a,11a)を設けたものである。また、裏面フィルム(14)は、表面フィルム(11)及び空収納室(11a,11a)より一回り大きく、かつ表面フィルムの周囲に余白部(14a,14a)を設けた構成である。次に、このいずれか一つの表面フィルム(11)による収納室(11a)に内容物(30)を充填した後、裏面フィルムで収納室底部や空収納室を密封して、しかも前記空収納室(11a,11a)部分の表面フィルム(11)、裏面フィルム(14)或いはこの両面には多数の外気取り入れ用の通気孔(15)が設けられていることを特徴とするものである。   As shown in FIG. 1, the configuration of the two-chamber disposable warmer packaging material according to the present invention is a heating element such as charcoal, iron powder, and a water-absorbing material on a surface film appropriately formed in a tray shape, a bag shape, or the like. A two-room type disposable warmer wrapping material having a back side sealed with a back film after filling the contents, wherein the tray-shaped surface film (11) is separated into a plurality of storage chambers, The two storage chambers (11a) are filled with the contents (30), and the empty storage chambers (11a, 11a) divided into one or both sides are provided. The back film (14) is larger than the front film (11) and the empty storage chambers (11a, 11a), and has a configuration in which blank portions (14a, 14a) are provided around the front film. Next, after the storage chamber (11a) of any one of the surface films (11) is filled with the contents (30), the bottom of the storage chamber or the empty storage chamber is sealed with the back film, and the empty storage chamber The surface film (11), the back film (14) or both surfaces of the (11a, 11a) portion are provided with a large number of vent holes (15) for taking in outside air.

また、図2(A)に示すように、前記表面フィルム(11)の片側或いは両側に設けた空収納室(11a,11a)は、裏面フィルム(14)と容易に剥離可能な二箇所の弱シール部分(12,12)により隔絶区分けされているもので、これにより表面フィルムを複数の収納室、空収納室に区分けしたものである。   Further, as shown in FIG. 2A, the empty storage chambers (11a, 11a) provided on one side or both sides of the surface film (11) have two weak spots that can be easily peeled off from the back film (14). These are separated from each other by the seal portions (12, 12), whereby the surface film is divided into a plurality of storage chambers and empty storage chambers.

また、前記裏面フィルム(14)は、表面フィルム(11)による収納室(11a)及
び空収納室(11a,11a)より一回り大きく、かつ表面フィルムの周囲に余白部(14a,14a)を設けた構成である。この余白部(14a,14a)に、前記表面フィルム(11)の周囲を強シールにより密封したものである。さらに、図2(B)に示すように、裏面フィルムで収納室底部や空収納室底部を密封して、しかも前記空収納室(11a,11a)部分の裏面フィルム(14)には多数の外気取り入れ用の通気孔(15)が設けられている。
Further, the back film (14) is slightly larger than the storage chamber (11a) and the empty storage chamber (11a, 11a) of the front film (11), and a blank portion (14a, 14a) is provided around the front film. It is a configuration. The margins (14a, 14a) are sealed around the surface film (11) with a strong seal. Further, as shown in FIG. 2B, the bottom of the storage chamber or the bottom of the empty storage chamber is sealed with a back film, and a large amount of outside air is applied to the back film (14) in the empty storage chamber (11a, 11a). An intake vent (15) is provided.

次に、本発明の2室式の使い捨てカイロ包装材の使用時は、図3に示すように、複数室に隔絶された表面フィルムと裏面フィルムとによる弱シール部分(12,12)を剥離して収納室、空収納室を一体にして、この何れか一つの収納室(11a)に充填した内容物(30)の一部を空収納室(11a,11a)内に移動させる(振り分ける)ことにより、元の空収納室底部の裏面フィルムの多数の外気取り入れ用の通気孔(15)から外気が入り内容物全体が発熱するものである。さらに裏面フィルムだけでなく、空収納室の表面フィルム、裏面フィルム或いはこの両面に通気孔を設けることも可能である。   Next, when the two-chamber disposable warmer packaging material of the present invention is used, as shown in FIG. 3, the weakly sealed portions (12, 12) formed by the surface film and the back film separated from each other are peeled off. The storage chamber and the empty storage chamber are integrated, and a part of the contents (30) filled in any one of the storage chambers (11a) is moved (sorted) into the empty storage chambers (11a, 11a). As a result, outside air enters through the large number of outside air intake holes (15) in the back film at the bottom of the original empty storage chamber, and the entire contents generate heat. Furthermore, not only the back film, but also air holes can be provided on the surface film, the back film, or both surfaces of the empty storage chamber.

本発明に使用する表面フィルム(11)の詳細は、バリア性フィルムを基本として、内面にイージーピールシーラント貼ったものが良い。シーラントとしてはカイロの発熱温度考慮して、発熱温度よりも融点の高いものが望ましいが、ある程度低温シール性が無いと充填機スピードに制約がでるので、融点が70℃から160℃程度のものが望ましい。材料としては、ポリエチレン系イージーピールフィルム、ポリプロピレン系イージーピールフィルム等を用いて、シール圧力やシール温度で開封強度をコントロールできるタイプのものが望ましい。また、バリアフィルムとしては、アルミ箔、透明蒸着フィルム、ポリ塩化ビニリデンコートフィルムを使用することができる。また、シーラント層の外側に内容物(中身)が見えないように、印刷等による隠蔽層やアルミ蒸着フィルムを用いることでも構わない。   As for the details of the surface film (11) used in the present invention, it is preferable that an easy peel sealant is applied to the inner surface based on a barrier film. In consideration of the heat generation temperature of the warmer, a sealant having a melting point higher than the heat generation temperature is desirable, but if there is no low temperature sealing property, the filling machine speed is limited, so that the melting point is about 70 ° C to 160 ° C. desirable. The material is preferably of a type in which the opening strength can be controlled by a sealing pressure or a sealing temperature using a polyethylene easy peel film, a polypropylene easy peel film or the like. Moreover, an aluminum foil, a transparent vapor deposition film, and a polyvinylidene chloride coating film can be used as a barrier film. Further, a concealing layer or aluminum vapor deposition film by printing or the like may be used so that the contents (contents) cannot be seen outside the sealant layer.

次に、裏面フィルム(14)は、基本的に表面フィルムと同様の構成であるが表面フィルムと異なる点は、
・発熱開始時に空気中の酸素を取り入れるための通気孔(15)を一部に設けておく
ことが必要である。
Next, the back film (14) is basically the same structure as the surface film, but the difference from the surface film is that
-It is necessary to provide a part of the ventilation hole (15) for taking in oxygen in the air at the start of heat generation.

また、表面フィルムのイージーピールフィルムとシール可能、かつイージーピール可能なフィルムであれば通常のシーラントフィルムでも構わない。但し、表裏の両方のフィルムをイージーピールフィルムにする必要はない。   Moreover, a normal sealant film may be used as long as it can be sealed with an easy peel film as a surface film and can be easily peeled. However, it is not necessary for both the front and back films to be easy peel films.

さらに、発熱体(内容物)充填時の「強シール部」と「要事に剥離させる弱シール部」の強度コントロールの方法としては、
・強シール部シール時は温度と圧力を高く設定し、弱シール部シール時は温度と圧力
を低く設定して、それぞれ別々にシールする(2回シール)。
Furthermore, as a method of strength control of “strong seal part” and “weak seal part to be peeled off as needed” when filling the heating element (contents),
・ Set the temperature and pressure high when sealing a strong seal, and set the temperature and pressure low when sealing a weak seal, and seal each separately (twice sealing).

・強シール部はシールバーを高くして、弱シール部を低く設定したシールバーを用い
て、同時シールをする。
・ Use a seal bar with a high seal bar for the strong seal and a low seal for the weak seal.

等が考えられるが、上記方法を組み合わせたり、他の方法で実施しても良い。さらに、弱シール部のみに、イージーピールフィルムのリボンを挟み込んでシールし、使用時に剥離できるようにしておく方法も可能である。   However, the above methods may be combined or implemented by other methods. Furthermore, it is possible to use a method in which an easy peel film ribbon is sandwiched and sealed only in the weak seal portion so that it can be peeled off during use.

なお、空気中の酸素を取り入れるための通気孔の孔空け加工は発熱体である炭、鉄粉、吸水性素材等の内容物より小さい孔を、微小な針り等で物理的に空けたり、放電やレーザー等で焼き空けたりする方法を使用することができる。   In addition, the hole drilling process for taking in oxygen in the air is to make a hole smaller than the contents of charcoal, iron powder, water absorbent material etc. as a heating element physically with a fine needle or the like, A method of baking with a discharge or a laser can be used.

以下に具体的な実施例を詳細に説明する。   Specific examples will be described in detail below.

エチレン(VMLLDPE)をドライラミネートし、蒸着リニア低密度ポリエチレンのポリエチレン(PE)面にリニア低密度ポリエチレン(LLDPE)を30μmエキストルーダーラミを施した。また、内袋用の裏面フィルムとして、上記内袋用の表面フィルムと同一構成品のものに、実施例1と同様に内容物が零れない程度のピンホールを空けて裏面フィルムとする。この表面フィルムと裏面フィルムを用いて、「炭、鉄粉、吸水性材料」等のカイロ内容物を充填して四隅をシールした(サイズ:50×80mm角)。さらに、この外袋として構成が、塩化ビニリデンコート延伸ポリプロピレン(KOP)/「VA含有量10%のエチレン酢酸ビニル共重合体(EVA)」30μmのもので外袋を作成し、さらに包装する。
(Comparative Example 1)
As Comparative Example 1, a warmer bag similar to the conventional one was manufactured and used as a comparative product. First, as a surface film for the inner bag, nylon (Ny) having a thickness of 15 μm and vapor-deposited linear low density polyethylene (VMLLDPE) having a thickness of 20 μm are dry-laminated, and the linear low-density polyethylene is deposited on the polyethylene (PE) surface of the vapor-deposited linear low-density polyethylene. (LLDPE) was subjected to 30 μm extruder lami. Further, as the back film for the inner bag, a pin film having the same configuration as the above-described surface film for the inner bag is provided with a pinhole that does not spill the contents in the same manner as in Example 1 to obtain a back film. Using this surface film and the back film, the contents of the body such as “charcoal, iron powder, water-absorbing material” were filled and the four corners were sealed (size: 50 × 80 mm square). Further, the outer bag is made of vinylidene chloride coated polypropylene (KOP) / “ethylene vinyl acetate copolymer (EVA) with 10% VA content” 30 μm, and further packaged.
