A Bag

Abstract

This invention relates to a bag. More particularly, the invention relates to a sling-type wearable bag having a waterproof pocket (12) for receiving a heat source, (i.e. a hot water bottle) therein, and a hand-warming pocket (30) located therein between the waterproof pocket and a layer (20, 22) of heat reflecting and/or insulating material.

1 . A bag including:
 a primary pocket for receiving a heat source therein, the primary pocket being formed by first and second layers of water impermeable material connected to one another along at least a portion of their respective edges thereby to define, along an unconnected portion of the edges, a primary access opening for accessing an interior of the primary pocket;   at least a first layer of heat reflecting and/or insulating material lying substantially over the first water impermeable layer of the primary pocket for: (i) operatively reflecting heat radiating from the primary pocket back towards it; and (ii) operatively slowing heat loss from the primary pocket; and   a secondary pocket for receiving a user's hands or other object therein, the secondary pocket being located between the first water impermeable layer and the first heat reflecting and/or insulting layer.   
     
     
         2 . A bag according to  claim 1  including a second layer of heat reflecting and/or insulating material lying substantially over the second water impermeable layer of the primary pocket such that the first and second heat reflecting and/or insulting layers jointly envelope the primary pocket therein. 
     
     
         3 . A bag according to  claim 2  including a first outer layer lying substantially over the first heat reflecting and/or insulting layers, and a second outer layer lying substantially over the second heat reflecting and/or insulting layers such that the first and second outer layers jointly envelope the first and second heat reflecting and/or insulting layers. 
     
     
         4 . A bag according to  claim 3 , wherein the edges of the first and second water impermeable layers are connected to one another along a fold line, or by one of at least welding or stitching such edges to one another. 
     
     
         5 . (canceled) 
     
     
         6 . A bag according to  claim 4 , wherein edges of the first and second heat reflecting and/or insulting layers are connected to one another along at least a portion of their respective edges thereby to form a heat reflecting and/or insulating pouch for receiving the primary pocket therein, the heat reflecting and/or insulating pouch defining along unconnected edges of the first and second heat reflecting and/or insulting layers a secondary access opening substantially coinciding with the primary access opening of the primary pocket, and further wherein the primary pocket and the heat reflecting and/or insulating pouch are connected to one another at least near their respective primary and secondary access openings such that the primary and secondary access openings jointly form a single common access opening into the primary pocket. 
     
     
         7 . A bag according to  claim 6 , wherein edges of the first and second outer layers are connected along the connected edges of the heat reflecting and/or insulating pouch. 
     
     
         8 . A bag according to  claim 7 , wherein the connected edges of the heat reflecting and/or insulating pouch, and the connected edges of the first and second outer layers, are connected along a fold line or by stitching such edges to one another. 
     
     
         9 . A bag according to  claim 8 , wherein fastener(s) extend along, or are spaced along, each of the unconnected edges of the common access opening for enabling the common access opening to be opened and closed. 
     
     
         10 . A bag according to  claim 9 , wherein the fasteners are a water-resistant zip, and further wherein the common access opening is located near a first end of the bag, with the second pocket being located nearer an opposing second end of the bag than to the first end thereof. 
     
     
         11 . A bag according to  claim 10 , wherein the bag comprises first and second opposing sides extending between the opposing first and second ends, and further wherein at least one of the first and/or the second opposing sides define a tertiary access opening into the one or more second pockets. 
     
     
         12 . A bag according to  claim 11 , wherein the second pocket is made up of a sleeve extending between each of the tertiary access openings defined on each of the first and the second opposing sides of the bag. 
     
     
         13 . A bag according to  claim 12 , wherein the bag comprises an adjustable strap for securing the bag to the body of a user such that the first or the second outer layer operatively lies in contact with the body of the user. 
     
     
         14 . A bag according to  claim 13 , wherein the adjustable strap comprises opposing first and second ends, the first end of the strap extending from the first end of the bag, with the second end of the strap extending from one of the first or the second opposing sides of the bag at a location there along nearer the second end of the bag such that the bag is wearable by the user as a sling bag. 
     
     
         15 . A bag according to  claim 14  including a tertiary pocket located on the strap near a first end thereof, the strap defining a quaternary access opening into the tertiary pocket, with quaternary access opening having zip fasteners located along unconnected edges thereof for opening and closing the quaternary access opening. 
     
     
         16 . A bag according to  claim 15  including a secondary strap for further securing the bag to the body of the user, the secondary strap having: (i) a first end extending from the side of the bag from which the second end of the adjustable strap extends; and (ii) a second end extending from the side of the bag opposite the side from which the second end of the adjustable strap extends. 
     
     
         17 . A bag according to  claim 16 , wherein the heat source is from a group of heat sources including chemically or electromagnetically activated heat pads or packs, chemically or electromagnetically activated heat bags and hot water bottles. 
     
     
         18 . A bag according to  claim 17 , wherein the first and second water impermeable layers are made from a waterproof, breathable polyurethane laminated fabric with a thickness of about 2 millimetres. 
     
     
         19 . A bag according to  claim 18 , wherein the first and second heat reflecting and/or insulting layers are made from a breathable polyester based fabric, the polyester fibres thereof being needle punched through a non-woven substrate and through a reflective metalized poly film. 
     
     
         20 . A bag according to  claim 19 , wherein the polyester based fabric is laminated on both sides with a material restricting migration of polyester fibres outwardly towards the first and the second outer layers. 
     
     
         21 . A bag according to  claim 20 , wherein the first and the second outer layers are made from a soft-touch, pliable material, and further wherein the connected edges of the first and second water impermeable layers are stitched prior to being welded.
