The present disclosure is directed to a heating pad that conforms to body parts of a user. The conforming heating pad can be worn to provide heat relief on different parts of a user's body. In an embodiment, a conforming heating pad includes a first layer on a posterior side of the heating pad, a second layer, a third layer, and a fourth layer on an anterior side of the heating pad. A continuous heating element is distributed throughout the second layer. The continuous heating element is capable of being selectively heated to increase the temperature of the heating pad. The third layer has a plurality of cavities formed in it. Each cavity holds a plurality of beads. When the heating pad is applied to a body portion of a user, the weight of the beads applies a force against the conductive heating element, the second layer, and the first layer to thereby conform them to the body portion of the user.

An ice pack comprises a plastic sac with an external surface, the plastic sac forming an interior chamber, a substance within the interior chamber capable of absorbing thermal energy, and a coating, which contains one or more antimicrobial agents, on the external surface. The substance can comprise water, including polymer beads mixed with the water. The one or more antimicrobial agents can include a quaternary ammonium ion or salt thereof, such as a silane quaternary ammonium ion or salt thereof. The silane quaternary ammonium ion or salt thereof can be 3-(trimethoxysilyl)propyldimethyloctadecyl ammonium ion, 3-(trimethoxysilyl)propyldimethyloctadecyl ammonium chloride, 3-(trihydroxysilyl)propyldimethyloctadecyl ammonium ion, or 3-(trihydroxysilyl)propyldimethyloctadecyl ammonium chloride. Instead of an ice pack, the apparatus comprising the coating containing one or more antimicrobial agents can be an object that is used around injured people and/or perishable items such as heating pads, coolers, and ice pack carriers.

This film for an outer bag is a film that is used in an outer bag for containing a chemical body warmer. The film contains at least a deposition film layer obtained by depositing a metal and/or a metal compound. and the film has an oxygen permeability. at 50? C. of 11.4 to 62.8 cc/m.sup.2?day?atm. The film forms the outer bag of a chemical body warmer.

Packs for providing heat or cold to a body part or parts. In some embodiments, packs comprising an outer flexible shell or skin housing or carrying a plurality of beads mixed in combination with a liquid or gel. In some embodiments, packs, which can be (or are) configured into various shapes, which contain heads in combination with a liquid or gel solution, which can be heated or cooled for application, thereafter, to a body part for providing hot or cold therapy to the body part.

An outer bag for disposable body warmer packaging and a disposable body warmer are provided that are excellent in a gas barrier property that inhibits permeation of oxygen gas, water vapor, and the like, which can allow swelling due to hydrogen gas generated during a storage period to be prevented. Provided is an outer bag for disposable body warmer packaging having an accommodating portion accommodating a disposable body warmer accommodated in an air-permeable inner bag and generating heat through contact with air, the outer bag comprising a low air-permeability portion having an oxygen permeability of 1.5 to 20 cc/m.sup.2.Math.day.Math.atm measured at 20? C. and 90% RH and having a water vapor permeability of 0.05 to 10 g/m.sup.2.Math.day measured at 40? C. and 90% RH; and an air-impermeable portion having an oxygen permeability of 1.3 cc/m.sup.2.Math.day.Math.atm or lower measured at 20? C. and 90% RH and a water vapor permeability of 2.0 g/m.sup.2.Math.day or lower measured at 40?

A therapeutic device such as an eye mask for delivery of moist heat therapy to a body part such as an eye of a human or animal subject. Example devices are configured to be worn with one or more eye coverage portions positioned over the subject's eye(s). The eye coverage portions have a front side configured for placement against the treated body part, and a back side opposite the front side. A moisture barrier material positioned at or adjacent the back side substantially prevents moisture from escaping from the back side and directs moist heat delivery through the front side and toward the body part to be treated.

A cooling pack is provided that can both maintain the human body at a suitable, low temperature and ensure a sufficient usage time. The present invention, in one aspect thereof, is directed to a cooling pack that cools a human body. The cold storage layer includes: a freezing medium having a phase transition temperature specified in a range of temperature suitable to maintain the human body at low temperature; and a cold-storage-layer-packaging member containing the freezing medium therein. The buffer layer includes: an antifreeze medium flexible at the phase transition temperature of the freezing medium; and a buffer-layer-packaging member made of a flexible material and containing the antifreeze medium therein. The buffer layer has a prescribed thermal conductivity, thermal diffusivity, thermal effusivity, and heat transmission coefficient. The buffer layer is brought into contact with human skin to transfer heat between the human body and the cold storage layer.
