The utility model is that related one kind can be intermittently using its warm packet, primary structure includes that a warm warm Bao Benti, the bag body and one for storing the warm packet ontology completely cut off the engaging portion of outside air for sealing the bag body, another with for the warm Bao Benti in receiving use and having the ventilative object of effect of keeping warm. By above structure, when user is intended to using the utility model, warm packet ontology need to only be taken out from bag body, contact it with air, it can start to generate heat, and warm packet ontology can be placed in ventilative object and be kept warm, in addition when use to be suspended, also only warm packet ontology need to be put back to bag body, and bag body is sealed really with engaging portion. Thereby, so that the heating effect of the utility model is had the characteristic that interval uses, and then extend its Use Limitation.本新型為有關一種可間歇使用之暖暖包，主要結構包括一暖暖包本體、一供收納該暖暖包本體之袋體及一供密封該袋體而隔絕外界空氣之結合部，另附有供收容使用中之暖暖包本體且具保暖功效之透氣物。藉由上述結構，使用者欲使用本新型時，只需將暖暖包本體自袋體取出，使其與空氣接觸，便可開始產生熱量，並可將暖暖包本體置入透氣物而得以保暖，另外欲暫停使用時，亦只需將暖暖包本體放回袋體，並以結合部確實密封袋體即可。藉此，使本新型之發熱效果具間歇使用之特性，進而延長其使用時效。
