Disclosed is a self-heating thermal-insulation multilayer film comprising a structure of at least three layers, which from outside to inside are respectively: an outer layer (1) formed of an air permeable material; a heat-generating layer (2) loaded with heat-generating composition (21) that generates heat on contact with air, at least an upper sealing surface of the heat-generating layer that is in contact with the outer layer being formed of an air permeable material; and an thermal-insulation layer (3) formed of a material having waterproof and thermal-insulation properties. The present self-heating thermal-insulation film is structurally simple, is not constrained by environmental resources, does not require energy supply from an external energy source, is safe and stable, uniformly generates heat, and can effectively prolong heating time and reduce peak heating temperature. The present self-heating thermal-insulation film can be manufactured into a three-dimensional face mask, a face mask, or an eye mask.

Moreover, the one or more strips may be configured to emit energy to the underlying region of skin and where the one or more strips are shaped to follow a location of one or more meibomiam glands contained within the underlying region of skin.

A handheld multi-tip scraping and moxibustion device, including: pushing and scraping air-guiding tips distributed on a panel each having a through-cavity; and a moxa burning chamber communicating with the through-cavity to enable heat and air in the moxa burning chamber to be discharged gradually for use through the pushing and scraping heat-conducting and air-guiding tips. The pushing and scraping air-guiding tips including a first set of pushing and scraping heat-conducting and air-guiding tips located in a middle portion of the panel and a second set of pushing and scraping heat-conducting and air-guiding tips located around the first set of pushing and scraping air-guiding tips, wherein the height of the first set of pushing and scraping heat-conducting and air-guiding tips is less than the height of the second set of pushing and scraping heat-conducting and air-guiding tips in order to form a multi-layered stepped air discharge.

Disclosed are thermoregulatory systems. In particular, thermoregulatory devices are incorporated into garments for warming and cooling a user's body. Thermoregulatory devices are waterproof and breathable, which allow thermogenerators such as hot packs and cold packs, to remain dry while still allowing air flow such that thermogenerators using air-activated chemical reactants remain active. Thermoregulatory devices are particularly useful with garments maintaining the thermogenerators close to the body's core where they will be most effective. The thermoregulation systems advantageously allow a user to selectively position thermoregulatory devices in different regions of the user's body to self-regulate core body temperature.

A heating device having at least one package surrounding a hygroscopic salt and a heater mix having at least a metal reactant. The heating device may include a source of moisture positioned in the package, the source of moisture initially generating an atmosphere having nearly 100% relative humidity inside the package. The hygroscopic salt is spatially separated from the source of moisture within the at least one package and positioned so as to absorb moisture out of the atmosphere to form an electrolyte, and the hygroscopic salt is further positioned so that the electrolyte generated by the hygroscopic salt is in contact with the heater mix. Rather than have an internal source of moisture, the at least one package may be water vapor permeable to allow ambient moisture from the atmosphere to enter the interior of the package to combine with the hygroscopic salt to generate an electrolyte.

It is an object of the present invention to provide a chemical body warmer that achieves a sufficient heating effect even in a low-temperature environment at about 10° C. or less. A chemical body warmer including a flat housing including one or a plurality of cells each containing an exothermic composition that generates heat upon contact with air, wherein a total area of the cell or the plurality of cells in a plan view of the housing is 200 cm.sup.2 or more, and the chemical body warmer is used by being placed under a blanket.

Provided is a heating body that enables high-speed production using a conventional rotary heat-sealing roll, has a wearing portion with sufficient strength to use by inserting a hand or the like, thereby being used safely and conveniently, and can be worn on the body or the like without being adhered thereto, and a method for producing the same. An example of one aspect of the present invention is a heating body in which a heat-generating composition that generates heat in the presence of air is accommodated in a bag body formed by heat sealing a one-surface side laminated base material comprising a first base material and a second base material, and a covering material, at a peripheral edge portion thereof, characterized in that: the first base material has one surface being a nonwoven fabric layer and the other surface being a heat sealable resin layer; the second base material is a sheet in which an olefin-based nonwoven fabric layer and a resin film are laminated using an olefin-based resin; the first base material and the second base material are capable of forming a space into which a body part can be inserted or held, in a part surrounded by the peripheral edge portion; and in a heat sealed part of the bag body peripheral edge portion, the heat sealable resin layer of the first base material and the nonwoven fabric layer of the second base material are bonded together, and the resin film of the second base material and the covering material are bonded together; as well as a method for producing the same.

Provided is a method for efficiently producing products having good heat generation performance without reducing the production speed by delaying or preventing the start of heat generation of heat-generating compositions/heating elements during production or before sealing to an outer bag. Provided is a production method capable of avoiding unevenness of a heat-generating compositions in a bag/container or formation of a portion not filled with heat-generating compositions. A method for producing a heating element including a heat-generating composition that generates heat upon reaction with oxygen in air includes encapsulating a heat-generating composition precursor including a mixture containing a water-insoluble component of the heat-generating composition in an air-permeable bag/container formed of a water-permeable packaging material at least in part. The method also includes injecting a liquid component of the heat-generating composition into the heat-generating composition precursor through the water-permeable packaging material from a nozzle tip in contact with the water-permeable packaging material.

A self-heating warming blanket includes a pliable outer shell forming a liquid impermeable enclosure. A heat generation layer disposed inside the enclosure has a plurality of liquid permeable heater compartments containing an exothermic reactant. The blanket also has a heater activation system including a sealed bladder containing an activator liquid inside the enclosure. An activation strip extends from outside the outer shell into the enclosure. One segment of the strip is an unsealing segment connected to the bladder. Another segment of the strip is a handle segment outside the outer shell. Pulling on the handle segment opens the bladder and releases the activator liquid into the enclosure where at least a portion of it permeates at least one heater compartment and combines with the exothermic reactant contained therein to initiate an exothermic chemical reaction that heats the warming blanket.
