Described are various embodiments of a cooling pack. In one such embodiment a cooling pack is provided for cooling a crotch region of a human while seated on a seating surface, the cooling pack comprising a tapered container for holding a cooling material therein, and defined by tapering upper and lower surfaces drawing into a tapered edge to be positioned between the crotch region and the seating surface in use, thereby providing cooling for the region.

This invention provides a heating tool that is capable of significantly suppressing a reduction of an active ingredient contained in an adhesive layer. More specifically, the invention provides a heating tool comprising an exothermic composition containing an oxidation accelerator, an oxidizable metal powder, and water; an active ingredient-containing adhesive layer; and a vapor deposition layer, the exothermic composition being housed in an air-permeable container bag, the vapor deposition layer being disposed between the container bag and the adhesive layer.

A paper SAM pack with SAM inside and without refrigerant fluid inside, wherein an envelope of the paper SAM pack includes a paper component. A cold pack cooling system including an entrance for accepting refrigerant packs into the system, a conveyor for moving the refrigerant through the system, and a selector for selecting whether to send a cold pack which has passed through the system back to the entrance. An accumulator for cold packs in a cold pack cooling system wherein the accumulator is configured to sense when the accumulator is full of cold packs. Related apparatus and methods are also described.

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.

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 thermal pack including: a flexible pouch body having a plurality of pouch segments each defining a cavity; one or more straps integrally formed with a first end of the pouch body, where the pouch body has one or more openings for accepting a second end of the one or more straps for securing the pouch body to a body part. The thermal pack can also include a bendable and deformable support frame having at least two twisted wires on at least two longer sides of the pouch body and/or metallic cubes disposed in each of the cavities of the pouch segments, each of the metallic cubes having a metallic shell defining a cavity with a freezable substance.

Improvements in the cold pack with a sustained temperature of between 17-40 degrees Fahrenheit for over 2 hours and as long as 9 hours. The aloe and polyacrylamide cold pack can be configured so it does not continually condense or drip water for over 2 hours when using the ingredients of Ammonium C12-C15, Pareth Sulfate Ammonium C12-C15, Pareth Sulfate, Sodium Chloride, Poloxamer 124 DMDM Hydantoin Pent sodium Pentatate, Sodium Bisulfite. The main ingredients in regulating the ice pack temperature, longevity and hardness is the aloe, H2O and polyacrylamide ratio.

A heat pack using supercooled aqueous salt solution that resists premature activation at low temperatures is disclosed. The heat pack comprises two sheets that are bonded together to form a laminated sheet. The heat pack has a first and second compartment. A frangible seal separates the two compartments. One of the compartments contains a supercooled aqueous salt solution. The salt solution contains 15 to 25 percent glycerin by mass.

A flexible cold pack includes a cell layer and a flexible layer. The cell layer includes a plurality of cells that are coupled to one another. Each cell of the plurality of cells includes a first liquid associated with a first freezing temperature. The flexible layer is disposed adjacent to the cell layer such that the flexible layer spans the plurality of cells of the cell layer. The flexible layer includes a second liquid or flexible semi-solid disposed therein. The second liquid or flexible semi-solid is associated with a second freezing temperature that is lower than the first freezing temperature.

A fingertip warming device that can be used on either hand, will aid in warming of fingertips to help increase blood flow to the fingertips of the user for the purpose of easing the process of drawing blood, which will be used to check the user's glucose levels. The device will have warming elements either embedded in the distal end of fingertip slots/compartments or allow for the use of a heatable insert that will also reside in the distal end of the device for the purpose of warming the user's fingertips. The device will provide either flaps or a hole through which the user's fingertips can be exposed to allow for collection of a blood sample for testing glucose levels.
