A roll tensioner for use in maintaining a wrapping material cut edge of a wrapping material retained on a wrapping material roll located within a wrapping material box having an interior cavity with an interior front wall with a top cutting edge. The roll tensioner comprises a thin, flexible main body having distal and proximal end sections separated by a spring back reversion section, and formed having a first side and a second side. Attachment means, preferably an adhesive, is located on at least a portion of the proximal end section on the first side adapted to attach the proximal end section to the interior front wall of the wrapping material box. The spring back reversion section is composed of a material that has an immediate elastic response to a static load and is capable of substantially full recovery when the static load is removed. The distal end mechanically bends downward by way of the spring back reversion section in the interior cavity of the wrapping material box. The distal end section is adapted to rest against the wrapping material proximal to the wrapping material cut edge to retain the wrapping material cut edge in an upward, substantially parallel position to the interior front wall of the wrapping material box for easy grasping of the wrapping material cut edge by an end user.

Wrapping material roll tensioner system, method of manufacture and use
A dispensing box with a roll tensioner houses a material roll and maintains a material cutting edge in an upward position for easy grasping during use. The roll tensioner comprises distal and proximal end sections with opposing bottom tabs separated by a spring back reversion section. A roll tensioner slide assembly integrated in the front wall of the dispensing box has opposing parallel slits terminating at opposing parallel slots with parallel locking flaps. Opposing bottom tabs of a roll tensioner are inserted through the parallel slots, resting in a first position during non-use and adapted to be slid down into a second position in the parallel slits when later engaged for use to retain the material cut edge in the upward position for easy grasping. The locking flaps have break-away top and bottom walls abutting a bend wall and are in a stored position and later opened outward to a locking position during use to prevent movement of the roll tensioner.

A self-venting trashcan system for use with a trashcan having interior smooth sides and a bottom interior surface has an extruded rigid polymeric strip with an adjustable bend formed on its left and right sides bendable along a thin web for contacting smooth sidewalls of a trashcan. Along its height and perpendicular thereto a plurality of parallel easy-to-fracture lines are provided. The user breaks the polymeric strip to thereby adjust its height to be shorter than the height of the trashcan. The left and right sides of the polymeric strip are attached to the smooth sidewalls of the trashcan by double-sided pressure sensitive adhesive tape, leaving a gap or air entry/exit between the top and bottom of the polymeric strip and the top and bottom surface of the trashcan, respectively. During trashcan liner placement, air pockets are smoothed out. Air moves freely in both directions, entering/exiting, between the polymeric strip and the trashcan, and the trash filled plastic liner is readily removed without tearing or vacuum pull-back.
