Abstract

A bag dispenser includes a frame with a roller portion for receiving a bag roll defined by a plurality of bags attached to a leading bag to be dispensed, the roller defining a longitudinal axis. A brake plate is configured to capture the leading bag against the frame for providing frictional force on the leading bag to limit sliding thereof, the brake plate pivotally attached to the frame via a pivot arm, the brake plate pivotable with respect to the frame between a non-pivoted friction-application position and a pivoted bag roll-installment position, the pivot arm configured to pivot with respect to the frame along a pivot plane generally perpendicular to the longitudinal axis.

Claims

1. A bag dispenser comprising:

a frame including a roller portion for receiving a bag roll defined by a plurality of bags attached to a leading bag to be dispensed, the roller defining a longitudinal axis; and

a brake plate configured to capture the leading bag against the frame for providing frictional force on the leading bag to limit sliding thereof, the brake plate pivotally attached to the frame via a pivot arm, the brake plate pivotable with respect to the frame between a non-pivoted friction-application position and a pivoted bag roll installment position, the pivot arm configured to pivot with respect to the frame along a pivot plane generally perpendicular to the longitudinal axis;

wherein the frame further includes a pair of upwardly extending guide posts adjacent the brake plate, the guide posts defining spacing therebetween for receiving the leading bag and for receiving the pivotable brake plate when the brake plate is brought to the non-pivoted friction-application position to contact the leading bag, the guide posts configured for positioning the leading bag under the brake plate and configured for providing vertical side support surfaces for the leading bag during dispensing, wherein the brake plate defines a flat contact portion for capturing the leading bag against the frame for providing frictional force on the leading bag to limit sliding thereof and wherein the brake plate further includes a transition portion positioned behind the flat contact portion, the transition portion of the brake plate defining a curved contact surface that is convex to the leading bag for allowing the leading bag to slide smoothly while also providing additional frictional force on the leading bag.

2. A bag dispenser according to claim 1, further comprising a bag roll mounted to the roller portion of the frame.

3. A bag dispenser according to claim 1, wherein the roller portion of the frame is fixedly coupled to the frame and is configured to allow a cylindrical core of the bag roll to rotate therearound for dispensing of the bags.

4. A bag dispenser according to claim 1, further including a perforator for separating the leading bag from the plurality of bags of the bag roll, the perforator removably attached to the frame.

5. A bag dispenser according to claim 1, further comprising an accessory mount for mounting an accessory holder to the bag dispenser.

6. A bag dispenser according to claim 1, wherein the frame is removably mounted on a dispenser support, the dispenser support configured for mounting the frame on a mounting surface.

7. A bag dispenser according to claim 6, wherein the dispenser support is configured to allow height-adjustability for the frame with respect to the mounting surface.

8. A bag dispenser according to claim 6, wherein the dispenser support is configured to allow pivotability of the frame with respect to the mounting surface along a plane generally perpendicular to the pivot plane of the brake plate.

9. A bag dispenser according to claim 6, wherein the dispenser support defines a base and at least one post extending from the base to the frame, the base configured to be mounted to the mounting surface.

10. A bag dispenser according to claim 9, wherein the dispenser support defines the base, a base post attached to the base, a head post attached to the frame, and an intermediate post extending between the base post and the head post, the intermediate post rotatable with respect to the head post.

11. A bag dispenser according to claim 10, wherein one of the intermediate post and the head post defines a generally V-shaped self-centering groove configured to receive a spring-loaded pin extending outwardly from the other of the intermediate post and the head post.
