A chalk bag for climbers includes a flexible bag structure with an internal cavity for holding chalk and an upper opening providing a passage to the cavity when open. A closure device circumscribes the opening and when open configures the opening in substantially circular shape for receiving the hand of a climber for chalking. When closed, the closure device configures opposite walls of the bag structure in engagement with one another in a substantially half-circular arcuate configuration. The chalk bag is wedge shaped in side elevation view to dispose the shape-retaining opening in vertically open disposition when the climber is standing with the chalk bag secured at the waist in the small of the back. Consequently, the climber can access the chalk within the bag easily with either hand, and may open and close the bag with either hand and with only one hand.

A bag for receiving an article which are to be easily accessed with the hand, said bag comprising: a flexible bag structure having an opening to an internal cavity, said bag structure being adapted to receive and contain the article in said cavity; means for securing said flexible bag structure to a person; a closure device associated with said opening of said flexible bag structure, said closure device including means for in an open first position disposing said flexible bag structure at said opening in a shape-retaining substantially circular configuration providing a substantially circular passage into said cavity of said bag structure, and in a closed second position disposing opposite walls at said opening of said flexible bag structure adjacent to one another to substantially close said passage into an arcuate substantially half-circular shape; wherein said closure device includes a substantially rigid and substantially half-circular member partially circumscribing said opening and having a pair of opposite end portions, an elongate resilient flexible member also having a pair of end portions and also being of substantially half-circular shape in said open first position and said closed second position of said closure device, said flexible member partially circumscribing said opening in opposition to said rigid member in said open first position of said closure device, and hinge means attaching respective end portions of said substantially rigid member and said flexible member to one another so as to allow said flexible member to flex between said first and said second positions, in said closed second position said flexible member laying adjacent to said rigid member to urge opposite walls of said bag structure into association with one another at said opening, closing said opening into a substantially half-circular arcuate shape; wherein said hinge means of said closure device includes structure connecting adjacent end portions of said substantially rigid member and of said elongate resilient flexible member to one another and including an integral flexible hinge portion; and wherein said hinge means of said closure device includes a length of heat-shrink tubing connecting adjacent end portions of said substantially rigid member and of said elongate resilient flexible member to one another in spaced apart relation to provide therebetween a flexible integral hinge portion of said heat-shrink tubing.
