BACKGROUNDStretch film or wrap is generally known in the industry as a material that can be used to securely wrap a collection of objects together using the stretch material's resiliency and dinginess. Stretch wrap is typically understood to be a polyethylene stretch film that is generally dispensed from a roll for use in a variety of applications. For instance, stretch wrap is held against a collection of objects and dispensed and stretched around the collection of objects and wrapped over itself up to several times to cover and hold together the collection of objects. In the shipping industry, for example, a collection of materials may be placed on a pallet to secure such articles together during the shipping process. A collection of boxes placed on a pallet can be shipped as a single cohesive unit when bound together through wrapping with stretch wrap.
Typically, during application, a tension is applied to the stretch film as it is applied to the objects being wrapped. This tension stretches the film to facilitate a secure binding of the wrapped objects together. Most known devices work by rotating the film around a spindle core while tension is applied to the core of the stretch film to create drag so that when the stretch film unrolls, it is stretched tight around the package. However, conventional devices are often configured to require the user to bend over or reach up while applying the stretch film around the package. This can result in user fatigue or even injury when applying stretch film to packages at a level below the waist of the user or above the chest of the user.

In an example embodiment, a method for assembling the stretch wrap dispenser 100 includes among the following operations: inserting the lower roll holder and stand-up base 145 over the stem 110, beveled side up and rotating the lower roll holder and stand-up base 145 until it locks in place with the stem stud 147; inserting a stretch wrap material roll 150 over the stem 110; inserting the upper roll holder 140 over the stem 110, beveled side down and causing the stretch wrap material roll 150 to fit snugly between the lower roll holder and stand-up base 145 and the upper roll holder 140; placing the compression spring 130 over the stem 110; inserting a handle 115 through an open loop of the tension control pin lanyard 137 to which the tension control pin 135 is attached; sliding the handle 115 over the stem 110; and adjusting to a desired level of tension by compressing the compression spring 130 and inserting the tension control pin 135 through one of a set of holes 112 in the stem 110.
The illustrations of embodiments described herein are intended to provide a general understanding of the structure of various embodiments, and they are not intended to serve as a complete description of all the elements and features of components and systems that might make use of the structures described herein. Many other embodiments will be apparent to those of ordinary skill in the art upon reviewing the description provided herein. Other embodiments may be utilized and derived, such that structural and logical substitutions and changes may be made without departing from the scope of this disclosure. The figures herein are merely representational and may not be drawn to scale. Certain proportions thereof may be exaggerated, while others may be minimized. Accordingly, the specification and drawings are to be regarded in an illustrative rather than a restrictive sense.
The description herein may include terms, such as “up”, “down”, “upper”, “lower”, “first”, “second”, etc. that are used for descriptive purposes only and are not to be construed as limiting. The elements, materials, geometries, dimensions, and sequence of operations may all be varied to suit particular applications. Parts of some embodiments may be included in, or substituted for, those of other embodiments.
