Abstract

A garment applies heat to the neck, head or torso with air-activated chemical heating packets. The garment is formed from cloth and is preferably soft and sufficiently supple to conform to the body contours during use. The garment has at least one pouch positioned between two layers of cloth for holding the air-activated heat-producing packet. A layer of cloth between the heating packet and the body is a high pile cloth with air-trapping qualities for diffusing heat supplied by the heating packet to distribute the heat evenly to the body for assuring comfort for the user. In one form of the invention, the garment comprises a neck wrap, scarf, bandanna, a head covering in the form of a hat liner, or a cap insert. The neck wrap, scarf or bandanna includes an elongated pouch for holding the heating packet and has overlapping ends that can be fastened together by means of hook-and-loop fasteners. The head covering has side, rear and top portions, a face opening, and includes pouch positioned to hold the heating packets next to the ears of the user.

Dependent claims

A heating garment in combination with an inserted air-activated chemical heating packet that can produce overheating or a sensation of burning of the skin comprising,

a garment article formed from cloth for covering a portion of the body, said garment article being flexible and sufficiently supple to conform to the body contours,
said garment article having inner and outer adjacent layers of cloth forming a pouch therebetween for receiving and supporting the heating packet therein,
each pouch has an opening to enable the heating packet to be inserted into the pouch before use and removed after use,
said air-activated chemical heating packet comprises a flexible packet containing chemically reactive substances that provide an exothermic chemical reaction which increases the temperature of the packet to about 130.degree. F. to 140.degree. F. to provide heat for up to about 18 hours,
at least the inner layer of cloth of the pouch is a porous layer positioned between the heating packet and the person's body and comprising a high pile cloth including a multiplicity of fibers extending from a portion of the cloth for holding trapped air to control heat distribution by diffusing the heat supplied by the chemical heating packet to the body to enhance the comfort of the user,
the pouch is elongated horizontally to provide a passage that is substantially longer than the width of the chemical heating packet and extends in a generally horizontal direction when the garment is in use to support the heating packet so that the packet will rest in the pouch wherever it is positioned therein,
the heating packet is smaller than the pouch which extends substantially from one end of the garment to the other and the elongated shape of the pouch serves as a means for enabling the relatively smaller heating packet to be shifted within the garment to different positions throughout substantially the entire length of the garment in heat transfer relationship with different selected parts of the body for distributing heat to different points for providing optimum warmth and comfort for the user, and
the friction between the pouch and the packet holds the heating packet in the desired position in the pouch.

5 more elements

A heating garment in combination with an inserted air-activated chemical heating packet comprising,

a cloth head covering having left and right sides for covering the sides of the head, a top for covering the top of the head, and a rear portion for covering the rear of the head, said garment covering substantially the entire head except for the face and a face opening at the from of the garment,
said head covering is flexible and sufficiently supple to conform to the body contours,
said head covering has inner and outer adjacent layers of cloth forming a pouch therebetween which extends substantially from one end of the garment to the other for receiving and supporting the heating packet and the pouch has an opening to enable the heating packet to be inserted into the pouch before use and removed after use,
the pouch is elongated horizontally to provide a passage that is substantially longer than the width of the chemical heating packet and extends in a generally horizontal direction when the garment is in use to support the heating packet so that the packet will rest in the pouch wherever it is positioned therein,
the heating packet is smaller than the pouch and the elongated shape of the pouch serves as a means for enabling the relatively smaller heating packet to be shifted within the garment to different positions throughout substantially the entire length of the garment in heat transfer relationship with different selected parts of the body,
said air-activated chemical heating packet comprises a flexible packet containing chemically reactive substances that react to provide an exothermic chemical reaction which increases the temperature of the packet to about 130.degree. F. to 140.degree. F. to provide heat for up to about 18 hours,
at least the inner layer of cloth of the pouch has fibers extending from a portion of the cloth,
said head covering has fastener means for securing the head covering in place,
the pouch holds said heating packet in heat conductive relationship with the head during use, and
each such pouch has one of said openings therein for inserting and removing the heating packet from the garment.
