< Topic >It cools around the neck in commuting of the shirt wearing person of summer season and the time etc of field work, it offers the insulated tool which lightens heat.SolutionsInsulated tool is enclosed, in order the insulated medicine length of the synthetic resin make 1 - 6cm, in the bag body of the size side 1 - 7cm to become thickness 0.5 - 1.5cm, at the same time the bag body through the adhesion generation of width within 1cm in the side one string, in order at number 4 - 25 to become total length 5 - 50cm, to be a little larger than the insulated component and the insulated component which are concatenated and is formed the insulated component from the stowage which possesses the taking in and out possible opening. Adhesion generation of the insulated component is formed by the both ends part of cross direction and the joining segment of the bag body, furthermore the both ends part of cross direction of the insulated component in order to be able to take in and out easily in the stowage, has become the form which angle takes.< Choice figure >Drawing 1【課題】夏場のシャツ着用者の通勤や野外作業時などにおける首周りを冷やし、暑さを軽減する保冷具を提供する。【解決手段】保冷具は、保冷剤が合成樹脂製の縦1~6cm、横1~7cmの大きさの袋体に厚み0.5~1.5cmになるように封入され、かつ袋体が横一列に1cm以内の幅の接着代を介して4~25の数で全長5~50cmになるように連結されている保冷部材と、保冷部材よりやや大きくかつ保冷部材を出し入れ可能な開口部を有する収納部から構成される。保冷部材の接着代が横方向の両端部分および袋体の連結部分に形成され、さらに保冷部材の横方向の両端部分は収納部の中に容易に出し入れできるように角が取れた形状となっている。【選択図】図1
