Description

FIELD OF THE INVENTION

The present invention relates to stretch wrap hand dispensers produced from non-traditional polymers or natural materials,

BACKGROUND OF THE INVENTION

U.S. Pat. No. 10,077,137 relates to a combination carrying device that includes a rigid basket having a flexible nest therein. The flexible bag may be formed from one or more fabrics or like materials and form or define a tapered volume having a pair of handle extensions.

US patent publication 2011/0219631 relates to plastic cutlery and tableware made in at least two parts joinable to form a unitary utensil, serving piece, beverage container or non-food contacting tableware in which the two parts are made of different materials. The materials of the two parts differ in at least one of the following: color, type of plastic, grade of plastic, source of plastic, and additives such as the presence of an anti-microbial agent, transparency or reflectivity, Food-grade resins, for example, can be used for the heads of the cutlery while recycled resins can be used for the handles. Heads can be separately metallized and then joined to non-metallized handles.

US patent publications 2012/0046411 and 2015/0218354 relate to compositions including recycled resin components and medical devices and components made from such compositions. The compositions and medical devices are characterized as biocompatible and sterilization stable. The compositions include a recycled resin component and may include one or more of an anti-oxidant component, slip additive component, and anti-static component.

US patent publication 2009/0126204 relates to a product formed from a crop-based resin that decomposes into a compost within 120 days or less and is heat resistant being able to remain in hot water at a temperature of at least 190 degrees Fahrenheit for at least 15 minutes without any substantial loss in rigidity.

Handles that are used to dispense stretch film from a roll are historically produced using virgin polymers such as polyvinyl chloride or polypropylene. This is true for handles that are inserted into a roll's inner core, for handles that are slid over a roll's inner core, and for handles that are used in coreless applications. With consumers looking to produce less plastic waste and requesting more sustainable options, the present invention changes the basic material from which these handles are produced. The result is a fully functional handle that reduces the consumption of new petroleum based raw materials.
