Patent number: 10315804Abstract: A method for making a film bag with reinforced bag seams includes a film extruder that produces a continuous tube of film. A flattener produces a continuous web of flattened film which has an upper surface and a lower surface. A fold maker has a receiving portion positioned above the web and a displacing portion is positioned below the web that moves cyclically upward to a first position to locate a portion of the web into the receiving portion, thereby forming a fold. A fold retention device prevents the fold from opening. A presser flattens the fold against the web. A sealer seals through the fold, forming a reinforced bag seam. A cutter severs a sealed portion from an unsealed portion of the web. A transport mechanism moves the film from the extruder, through the flattener, into the fold maker, beneath the presser, into the sealer and to the cutter.Type: GrantFiled: October 6, 2014Date of Patent: June 11, 2019Inventors: Daniel Brian Tan, David H.

Patent number: 9850034Abstract: A self-opening bag includes front and real walls joined at their respective first and second side and bottom edges. The bag is folded at least once parallel to its side edges. At least one attaching feature is located on the outer surface of the bag adjacent the upper end and between the folded walls. The bag is releasably attached to a subsequent bag. The at least one attaching feature causes the bag to open as the bag is pulled from the subsequent bag. The once folded bag may be sealed at the bottom edges after folding to form a star-sealed bag bottom. The bags may be removably attached to each other at a perforation line and wound onto a compact roll for use with a bag dispenser. The bags may have an upper seam, a U-shaped cut and a pair of bag handles. The bags may be corona treated.Type: GrantFiled: May 12, 2017Date of Patent: December 26, 2017Inventor: Daniel Brian Tan

Patent number: 9140036Abstract: A bag container dispenser rack includes a containment structure that has an open first end and an opposite, second end. The structure is sized and shaped to fit slidably about a container dispenser for film bags and has an aperture at the second end. The aperture is sized, shaped and located to at least partially align with a dispensing opening in the container dispenser. A support stand is attached to the containment structure and provides connection to a surface. The support stand is pivotally mounted to an underside of the structure and optionally is securable in either a first, upper position or a second, lower position. A latch prevents unwanted removal of the dispenser from the rack. Two or more structures may be attached to the support stand, thereby providing a choice of bags. Openings are provided in the rack to provide visual access to outer surfaces of the dispenser.Type: GrantFiled: July 2, 2014Date of Patent: September 22, 2015Inventor: Daniel Brian Tan

Patent number: 9126362Abstract: An apparatus for corona treating film includes a source of film material and at least one transport roller that is rotatably mounted in a frame. The transport roller has a longitudinal axis and has a width greater than the film. First and second treater heads have first and second leading edges, first and second trailing edges and are mounted parallel to the longitudinal axis. The second leading edge is parallel to and spaced from the first trailing edge by a second predetermined distance. The film is transported over the roller and a high voltage electric arc is provided to the first and second treater heads. The roller is grounded and provides a return path for the electric current provided to the first and second treater heads, thereby corona treating the front side or back side of the film if a second roller and third and fourth treater heads are used.Type: GrantFiled: April 24, 2013Date of Patent: September 8, 2015Inventor: Daniel Brian Tan
