发明名称 Cooler bag
摘要 A cooler bag intended to be carried at one's back by means of a shoulder strap. The bag is constructed to include an outer layer or shelll and an inner waterproof bladder with the body of the bag having between the outer shell and the bladder a layer of insulation. While the bag is generally circular in cross-section, the bottom of the bag has a forward concave edge portion so as to fit the general contour of one's back. The shoulder strap is selectively connected to the bottom portion of the bag either at one side or the other depending on which shoulder is engaged by the shoulder strap. The bag also has a desirable closure arrangement including closure flaps which are folded into overlying locked relationship.
