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.

A method for producing an adhesive layer composition for producing a cooling sheet including a backing layer, an adhesive layer, and a liner layer, the method comprising the step of:

mixing a composition to be mixed containing water, an alum, sodium edetate, a polyacrylic acid, and a neutralized polyacrylic acid such that a mixing temperature becomes 5 to 23° C., to obtain an adhesive layer composition, wherein

in the composition to be mixed,

a content of the water is 69 to 938.24% by mass relative to a total mass of the composition to be mixed,

a content of the alum is 0.18 to 0.42% by mass relative to the total mass of the composition to be mixed,

a content of the sodium edetate is 0.08 to 0.18% by mass relative to the total mass of the composition to be mixed, and

a mass ratio between the content of the alum and the content of the sodium edetate (the content of the alum:the content of the sodium edetate) is 1:1 to 5.25:1.

The present invention provides a weighted article for assisting sleep, wherein the weighted article includes heating and cooling means. The weighted article is perforated by a series of channels, which contribute to the weight of the weighted article and allow the passage of a fluid that is continuously pumped throughout the weighted article while the weighted article is in use. The weighted article is connected to a control unit including means to thermoelectrical heat or cool the fluid such that a user of the weighted article is able to increase or decrease their body temperature.

An iron powder for an exothermic composition according to the present invention has a bulk density of 0.3 to 1.5 g/cm.sup.3. Furthermore, an exothermic composition according to the present invention contains the iron powder, a carbon material, a halide salt, and water. Furthermore, an exothermic body production method according to the present invention includes: forming a coated member by coating a base material sheet with a flowable exothermic composition containing the iron powder, a carbon material, and water; and adjusting an amount of moisture in the coated member by removing water from the coated member. Furthermore, the present invention is directed to a production method for the iron powder (an iron powder for an exothermic composition) including: a reducing step of reducing iron oxide to obtain reduced iron; and a step of milling the reduced iron. In the reducing step, the iron oxide is reduced by introducing iron oxide and a solid reductant with a volatile matter content of 10% by mass or more into a heating furnace whose internal portion contains no sulfur gas or is set to an air or inert gas atmosphere, and setting the internal portion to a reducing gas atmosphere through heating under a condition that an ambient temperature of the internal portion is from 900 to 1000° C.
