  • Patent number: 11241331
    Abstract: An object of the present invention is to provide a heat-generating device with which a warm sensation is persistently perceived, and which can effectively exert a heating effect. In a heat-generating device that is used by being attached to skin, (1) a packaging material constituting a skin attachment surface of a housing is formed of a laminated sheet in which at least a moisture absorption layer that absorbs moisture and a moisture barrier layer that blocks penetration of moisture are laminated in this order from the adhesive layer, (2) an adhesive layer is partially provided on a surface of the moisture absorption layer, and (3) a warming agent that allows an enhanced warm sensation to be perceived in the presence of moisture is contained in at least one of the adhesive layer and the moisture absorption layer. This heat-generating device thereby has improved persistence of a perceived warm sensation, and can exert a markedly high heating effect.

  • Patent number: 10195074
    Abstract: The present invention provides a disposable body warmer that makes it possible to suppress scattering of moisture contained in the exothermic composition from the outer bag, and thereby ensure a desired exothermic duration of the exothermic composition when the disposable body warmer is kept in an unused state for a long period of time. The disposable body warmer is structured such that an exothermic composition that contains moisture and generates heat by contact with air is enclosed in one or more air-permeable inner bags, which are accommodated in an airtight outer bag. The outer bag comprises two accommodation units that are partitioned from each other and capable of containing the one or more inner bags. The one or more inner bags each comprise at least one enclosure unit capable of enclosing the exothermic composition, and are accommodated in each accommodation unit in a manner such that at least one of the enclosure units is overlaid with another enclosure unit.
