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? C. and 90% RH, wherein a ratio of an area of the low air-permeability portion to a total internal area of the accommodating portion is 15 to 75%.

Disclosed is a system which employs a cooling or heating pad which is preferably a thin, flexible pad for placement at an intended area of the body. The pad includes a layer of highly conductive material which can be cooled or heated using a portable source of heat or cold material delivered to the conductive material by a delivery conduit. Valves can be included to regulate flow of the cooling or heating material from the source to the pad. The system can also include a dual-chambered canister for containing two different media for heating, cooling or for alternating heating and cooling the pad.

A therapeutic mask system for treatment of the eyes, including a mask portion for attachment to the head of a patient and an eye coverage pod that is detachably coupled to the mask portion. The mask portion can include an eye coverage portion comprising a receiver in which the pod is releasably secured. The pods can also be directly secured to a mask strap. The pod includes material for delivering thermal, moisture and/or medication therapy and treatment to the eye. The system can also include a heat-transmissive treatment pad positioned between the pod and the eye of the user.

The invention relates to heat products for single treatment and/or as self-therapy in the event of acute, recurrent and/or chronic states of pain, comprising heat-generating materials arranged in annular form.

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 including a first base material and a second base material, and a covering material, at a peripheral edge portion thereof. The first base material has a nonwoven fabric layer and a heat sealable resin layer; and 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. The heat sealable resin layer and the nonwoven fabric layer are bonded together, and the resin film of the second base material and the covering material are bonded together.

Provided is a multilayer film for a disposable body warmer outer bag, and a disposable body warmer, which are excellent in 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, and which are excellent in seal strength, impact resistance and weather resistance.

A disposable body warmer outer bag formed from a multilayer film comprising a first barrier layer (10) and a second barrier layer (20), wherein the first barrier layer (10) and the second barrier layer (20) consist of a polyvinylidene chloride layer (12) or a polyvinylidene chloride layer (22) obtained by coating at least one surface (upper portion in FIG. 1) of a heat-resistant resin substrate (11) or a heat-resistant resin substrate (21) with polyvinylidene chloride.

A gel-pack has a plurality of self-contained components organized as layers in an interior chamber of the gel-pack. Each layer may be inserted into, and removed from, the interior chamber individually. The components include a solid-state gel layer that stores thermal energy, a first radiant energy barrier that prevents the transfer of thermal energy radiating from an exterior of the gel-pack into the solid-state gel layer, and a second radiant energy barrier that reflects the thermal energy radiating from the user's body into the solid-state gel layer.

A cooling assembly is provided for cooling selected parts of the body of a patient to treat hyperthermia or to induce mild hypothermia in the treatment of strokes. The assembly includes a self-contained cooling unit containing a water supply, a battery operated refrigeration unit and circulating pump. A cooling member is connected to the cooling unit and is adapted for receiving cooled water and contacting selected parts of the patient to cool the patient. The cooling member can be a vest, wrap, blanket, chair, hood or cap.

A thermal pack holding apparatus includes a thermal pack holder including an interior cavity configured to receive a thermal pack, the interior cavity bounded by a face panel and an opposed back panel, the face panel is thermally conductive and the back panel is moisture-resistant.

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.
