Benefits of technology

"The present invention is a set of improvements to a cited invention co-authored by this inventor. The additional features are non-obvious and confer additional, valuable, and useful capabilities to the cited invention. The improvements include a clamp for closing and holding closed a polymer bag, a blade for cutting the bag, a split anvil for holding bag material, ribs on the inside of each clamp member for holding the bag and distributing the gripping force away from the hinge spring location, and an improved spring for holding larger bags. The invention also includes an additional tooth in the bag \"lips\" for easier drawing of the bag through the clip."

Problems solved by technology

Opening polymer bags is also a problem, because they are usually tightly sealed to prevent product degradation while on store shelves.

Embodiment Construction

[0024]The present invention is an improved clamp for safely opening, clamping, and resealing polymer plastic storage bags. As shown in FIG. 2 and FIG. 3, the improved bag clamp100 is comprised of an upper clamp member101 and a lower clamp member102 that are separated from each other as shown, the separation defining an opening103 through which a polymer bag can be drawn. The upper101 and lower102 members each include a lip104,105 that guides the polymer bag into the improved bag clamp opening103.

[0025]The upper and lower clamp members each possess a leading end portion106,107 for receiving the polymer bag. These end portions terminate in curved receptor edges108,109. The outer surface of each of the clamp members101,102 is smooth.

[0026]An open box-like structure112, having a slot113, is disposed on the inner surface of the lower clamp member102. An elongated member110, fixedly attached to the inner surface of the upper clamp member, is accepted in the slot113 for rotational movement...

Abstract

An improved bag clamp and bag cutter is presented that is a non-obvious increase in capability over this inventor's previous bag clamp / cutter invention. The improved clamp possesses a stronger spring, an improved cutting blade with safety guard, a springboard button for pressing the blade firmly against a bag surface, and other improvements.

Description

BACKGROUND OF THE INVENTION[0001]This invention relates to devices for use with bags of food, pet food, potting soil, and other bulk items. More particularly, this invention relates to devices used to close and open these types of bags.[0002]A previous invention, U.S. Pat. No. 6,105,217, “Bag Clamp”, was co-authored by this inventor, and this patent application is a set of improvements to that invention.[0003]As covered in the cited patent application, modern polymer plastic bags are useful containers for bulk foods, bulk pet foods, and other loose, granular or small-sized items. The bags have the drawback that they are difficult to close properly once opened. They usually have smooth or slick surfaces which are difficult to grab with closure devices.[0004]Polymer bags such as those under consideration here are often opened with the intention of closing and then re-opening then at a future time. Secure closure of the bag, to preserve product freshness for example, is necessary as is...
