Abstract:
A side seamed plastic produce bag includes a front wall and a taller back wall, first and second side edges sealed together and a seamless bag bottom. The taller back wall provides means for finding the bag opening. The bag is joined at the side edges to additional bags by a perforation. The bag is corona treated on at least one of the front and back walls and advertising or promotional material is printed on the corona treated surface. The invention includes means for manufacturing the bags and winding them onto cores or forming the bags into coreless rolls. Dispensers are provided for both the cored and coreless rolls. The dispensers include a vertical container with an open top that is mounted on a planar base. The container includes a vertical slit for dispensing the bags. The dispenser for cored rolls includes a vertical rod on which the core revolves.

Description:
FIELD OF INVENTION  
         [0001]    The invention pertains to plastic film produce bags. More particularly, the invention relates to plastic produce bags having no bottom seam, thus providing for increased resistance to rupturing, and to methods for making and dispensing the bags.  
         BACKGROUND OF THE INVENTION  
         [0002]    Various designs have been developed for plastic produce bags as well as for methods for making and dispensing the bags.  
           [0003]    U.S. Pat, No. 5,611,627 issued to Belias et al. is directed to an easy open thermoplastic bag. The bag is manufactured from a flattened tube of thermoplastic material with transverse heat seals. The transverse heat seals along with the sinusoidally oscillating paths form the tube into two halves or bags. The result of the transverse heat-seals and the cutting paths, is that two bags are formed with seamless bottoms. The sinusoidal cuts in the front and back portions of the tube respectively give rise to a mouth or opening for the bags with tabs that allow for the bags to be more easily opened.  
           [0004]    U.S. Pat. No. 4,164,170 issued to Nordin, discloses a method of making bags. The Patent describes the manufacturing of a string of bags from a hose-like blank. Since a hose-like blank is used, the bottoms of the resultant bags are continuous in nature and the sides of a bag are formed by welds with separation lines in order to separate one set of bags from another. The hose-like blank is cut into two substantially equal parts along a center line while the cutting lines are offset to form the handles of the finished bag.  
           [0005]    U.S. Pat. No. 4,811,418, issued to Reifenhauser is directed to a method for the manufacture of plastic bags with welded side seams. The patent describes the production of two bags side-by-side in parallel from tubular film that is fed in a first direction. The tubular film is cut in a sinusoidal configuration in the center of the film, thus forming two semitubes to form two side seam bags with welded side seams and handle opening portions.  
           [0006]    U.S. Pat. No. 2,444,685 issued to Waters is directed to the multiple fabrication method and apparatus for forming liquid-type envelope bags. A supply roll of material with defined edges is passed through feed rolls and around a former plate in order to bring the edges together along a line with a defined space between them. The edges ultimately form the opening of the envelope after having been cut by a cutter into separate envelopes. A pair of transverse welds are formed in the process and the paired envelopes are cut by means of cross-cut knife.  
           [0007]    U.S. Pat. No. 5,967,663 issued to Vaquero et al. is directed to a thermoplastic bag structure. The thermoplastic tube is cut into two portions by means of cutting instruments that form sinusoidal paths and hence sinusoidal cuts. Transverse heat seals and transverse perforations separate the tube into pairs of bags such that the folded bottom edge does not require heat sealing and the openings of the resultant bags have “tabs” so that they may be more easily opened.  
           [0008]    While other variations exist, the above-described designs for plastic produce bags are typical of those encountered in the prior art. It is an objective of the present invention to provide a produce bag without a bottom seam for additional strength in the bag bottom. It is a further objective to provide a produce bag that provides means to easily identify and open the bag. It is a still further objective of the invention to provide the above-described capabilities in a produce bag that can be easily dispensed from a roll using a compact and inexpensive dispenser. It is yet a further objective to provide a means to manufacture such produce bags using economical and reliable high-speed methods. While some of the objectives of the present invention are disclosed in the prior art, none of the inventions found include all of the requirements identified.  
         SUMMARY OF THE INVENTION
