Abstract

Official abstract text for this publication.

A dispenser for dispensing bags from a roll includes a base, a bag separator, and a swing arm pivotably mounted on the base that includes a roll retaining portion shaped and arranged for being received in an axial opening of the roll. The swing arm is pivotable with respect to the base about a pivot axis in a braking direction in which the roll retaining portion travels toward the base. A spring is operatively connected between the swing arm and the base to bias the swing arm in the braking direction whereby, when the roll retaining portion is received in the axial opening, the roll retaining portion engages the roll and urges the roll into braking engagement with the base.

First claim

Opening claim text (preview).

What is claimed is: 1. A dispenser for dispensing bags from a roll, the dispenser comprising: a base having a first end portion and a second end portion; a bag separator comprising tongue projecting from the base adjacent the first end portion thereof and configured to separate bags from the roll as the bags are pulled across the tongue; a swing arm pivotably mounted on the base and including roll retaining portion shaped and arranged for being received in an axial opening of the roll and engaging the roll therein, the swing arm being pivotable with respect to the base about a pivot axis in a braking direction in which the roll retaining portion travels toward the base; and a spring operatively connected between the swing arm and the base to bias the swing arm in the braking direction whereby, when the roll retaining portion is received in the axial opening, the roll retaining portion engages the roll and urges the roll into braking engagement with the base. 2. A dispenser as set forth in claim 1 wherein the spring comprises a torsion spring having a tangential end portion and a radial end portion. 3. A dispenser as set forth in claim 2 wherein the tangential end portion of the spring is secured to the swing arm for movement therewith and the radial end portion of the spring is engaged with the base. 4. A dispenser as set forth in claim 3 wherein the swing arm includes a knob configured to capture the tangential end portion of the spring. 5. A dispenser as set forth in claim 1 wherein the spring comprises a coiled portion and a segment of the swing arm is received in the coiled portion. 6. A dispenser as set forth in claim 1 wherein the swing arm includes a pin portion that defines the pivot axis and an intermediate portion extending radially of the pivot axis between the pin portion and the roll retaining portion. 7. A dispenser as set forth in claim 6 wherein the base includes a bearing collar, the pin portion of the swing arm including a bearing segment received in the bearing collar for rotation about the pivot axis. 8. A dispenser as set forth in claim 7 wherein the spring comprises a coiled portion and the pin portion of the swing arm includes a segment that is rotatably received in the coiled portion. 9. A dispenser as set forth in claim 8 further comprising a flange mounted on the pin portion of the swing arm, the coiled portion of the spring being captured between the flange and the bearing collar. 10. A dispenser as set forth in claim 7 wherein the pin portion has a threaded end segment projecting out of the bearing collar. 11. A dispenser as set forth in claim 10 further comprising a nut threadably mated with the threaded end segment of the pin portion to secure the swing arm to the base. 12. A dispenser as set forth in claim 7 wherein the bearing collar comprises an elongate tube. 13. A dispenser as set forth in claim 7 wherein the bearing collar is located adjacent the second end portion of the base. 14. A dispenser as set forth in claim 6 further comprising a knob mounted on the intermediate portion of the swing arm between the pin portion and the roll retaining portion. 15. A dispenser as set forth in claim 14 wherein the spring comprises a swing arm end portion engaged with the knob. 16. A dispenser as set forth in claim 6 wherein the roll retaining portion of the swing arm extends generally along an axis that is parallel to and spaced apart from the pivot axis. 17. A dispenser as set forth in claim 1 wherein the bag separator further comprises a guide scoop located between the tongue and the swing arm and defining a concave guide surface that is generally aligned with the tongue. 18. A dispenser as set forth in claim 1 wherein the bag separator further comprises a retainer member extending generally parallel to the tongue and located between the tongue and the swing arm immediately adjacent to the tongue. 19. A dispenser for dispensing bags from a roll, the dispenser comprising: a base having a first end portion and a second end portion; a bag separator comprising tongue projecting from the base adjacent the first end portion thereof and configured to separate bags from the roll as the bags are pulled across the tongue; a bearing collar mounted on the base adjacent the second end portion thereof; a swing arm comprising a pin portion, an intermediate portion, and a roll retaining portion, the pin portion extending from the first end of the intermediate portion along a pivot axis, the roll retaining portion extending from the second end of the intermediate portion along an axis parallel to and spaced apart from the pivot axis, and the intermediate portion extending between and connecting the pin portion and the roll retaining portion, the pin portion including a bearing segment that is rotatably received in the bearing collar to constrain the swing arm for pivoting movement about the pivot axis with respect to the base, the swing arm being pivotable with respect to the base about the pivot axis in a braking direction in which the roll retaining portion travels toward the base; and a spring comprising a base end portion, an opposite swing arm end portion, and a coiled portion extending therebetween, the coiled portion of spring being located adjacent the bearing collar and receiving the pin portion of the swing arm therein, the base end portion of the spring being engaged with the base and the swing arm end portion of the spring being operatively connected to the intermediate portion of the swing arm for conjoint movement therewith, the spring being oriented with respect to the swing arm and the base such that pivoting movement of the swing arm from a position in which the roll retaining portion is located adjacent the base in a direction opposite the braking direction deforms the spring whereby the spring imparts a biasing force upon the swing arm that urges the swing arm in the braking direction.
