Abstract

Apparatus for storing and dispensing paper bags, wherein the bags are stored in collapsed condition and are automatically opened upon successive removal of the bags from the apparatus. The apparatus includes a frame for slidably supporting a container having a bag storing chamber and a front opening, an opening bar at the front opening of the container engaging the folded bottom panel of the front-most bag, restraining means for engaging the opposite sides and top of the front-most bag and a resiliently biased pusher member for applying pressure to the rear of a stack of bags in the container and forcing them to the front opening.

Claims

1. Apparatus for storing and successively dispensing paper bags in opened condition, wherein each bag includes opposite side walls and opposite end walls connected by a bottom wall and being foldable between an open condition and a collapsed condition with the end walls folded between the side walls and the bottom wall folded against one of the side walls, said apparatus comprising a box-like structure defining a bag storing chamber and having a rectangular front opening and means for supporting a stack of substantially vertically arranged collapsed bags in said chamber with the upper end portion of said one side wall of the front-most bag in the stack exposed for manual gripping, restraining means adjacent the front opening for normally restraining the stack of bags in the chamber and for restraining the other side wall of the front-most bag when said one side wall is pulled from said restraining means, a transversely extending opening bar across the front opening and near the bottom thereof against which the entire lower half of the bottom wall of the bag engages, said opening bar being positioned below the restraining means and spaced inward of the restraining means such that the upper portion of the bags extends forward through the opening, a pusher member supported within said structure and engaging the back of the stack of bags, and means resiliently biasing said pusher member toward the front opening to continually maintain the front-most bag against the opening bar and the restraining means, whereby pulling upward on the one side wall of the bag causes unfolding of the bottom wall and opening of the bag as the bag is removed from the stack.

2. Apparatus as defined in claim 1, wherein the pusher member is guidably supported along a pair of parallel guide rods mounted at the lower end of the cabinet, and said guide rods also supporting the lower edges of the bags.

3. Apparatus as defined in claim 2, wherein said guide rods are removable from the cabinet in disassembly of the apparatus.

4. Apparatus as defined in claim 1, wherein said restraining means includes a pair of fingers at the top of the opening.

5. Apparatus as defined in claim 1, wherein said pusher member may be released to facilitate loading of bags.

6. Apparatus for storing and successively dispensing paper bags in opened condition, wherein each bag includes opposite side walls and opposite end walls connected by a bottom wall and being foldable between an open condition ad a collapsed condition with the end walls folded between the side walls and the bottom wall folded against one of the side walls, said apparatus comprising a frame, a box-like container having a front opening and defining a bag chamber for storing a stack of substantially vertically arranged collapsed bags, means for slidably supporting said container on said frame such that the container may be moved between bag loading and dispensing positions, means adjacent the front opening for normally restraining the stack of bags in the chamber and for restraining the other sde wall of the front-most bag when said one side wall is pulled from said restraining means, a transversely extending opening bar across the front opening and near the bottom thereof against which the entire lower half of the bottom wall of the bag engages, said bar being spaced inward of the restraining means such that the upper portion of bags extends forward through the opening, a pusher member supported within said container and engaging the back of the stack of bags, and means resiliently biasing said pusher member towards the front opening to continually maintain the front-most bag against the opening bar and the restraining means, whereby pulling upward on the one side wall causes unfolding of the bottom wall and opening of the bag as the bag is removed from the stack, said biasing means being bottomed at one end on said frame so that the biasing action is automatically released from the pusher member when the container is moved to the bag loading position for loading bags and automatically applied to the pusher member when the container is returned to the dispensing position.

7. Apparatus as defined in claim 6, wherein said means for slidably supporting said container on said frame includes a plurality of track and roller assemblies.

8. Apparatus as defined in claim 6, wherein said means for slidably supporting said container on said frame includes cantileverly supported rods extending from said frame and telescopically receiving tubular members carried by said container.

9. Apparatus as defined in claim 6, wherein said restraining means includes a tab at each side of the opening and a pair of fingers at the top of the opening.

10. Apparatus as defined in claim 6, wherein said opening bar is cylindrical.

11. Apparatus as defined in claim 10, wherein said bar is rotatably mounted.

12. Apparatus as defined in claim 6, wherein said pusher member has a forwardly extending portion at the upper end thereof to push the upper ends of the bags ahead of the lower ends thereof.

13. Apparatus as defined in claim 6, wherein said biasing means includes a coil spring.

14. Apparatus as defined in claim 6, wherein means is provided to prevent the pusher member from moving with the container when the container is in bag loading position thereby maintaining the pusher member in retracted position relative the container to permit loading of bags.

15. Apparatus as defined in claim 6, wherein said pusher member is guidably supported along a pair of parallel guide rods mounted at the lower end of the container, and said guide rods also supporting the lower edges of the bags.

16. Apparatus as defined in claim 13, wherein guide members are provided on the frame and the pusher member for maintaining the spring in alignment therewith.

17. Apparatus as defined in claim 14, wherein said frame and container includes means for retaining the container in dispensing position.
