Abstract: The present disclosure relates to a reclosable package or bag with a slider zipper, and further including a first gusset with a perforated line or similar line of weakness formed between the slider zipper profiles in order to provide tamper evidence and a second gusset formed below one zipper profile in order to allow the filled packaged to stand up for display purposes. This package or bag is typically bottom filled, but then displayed to the customer in the orientation with the bottom in the upper position and the zipper in the lower position. One alternative embodiment substitutes a press-to-close-zipper for the slider zipper. A further alternative embodiment omits the perforated line and provides for a separation in the web between the zipper profiles to form a mouth for the package or bag.

Abstract: A cutting tool for laminate flooring and the like for removing some or all of the retaining lip on a flooring plank to facilitate sliding the plank into place under an obstruction such as a door frame. The cutting tool comprises a main housing with a recess to allow it to be positioned against a flooring plank. An adjustment screw allows the cutting blade to adjust vertically to remove material from varying sizes of planks. An alternate embodiment of the cutting tool positions the cutting edge of the razor blade at the same vertical position as the retaining lip of the flooring plank to remove all of the retaining lip.

Abstract: A slider-zipper assembly in which the slider has a design lending itself to economical manufacture using an injection molding process. The slider comprises a frame that straddles the zipper, a plow supported by the frame and separating respective sections of two interlockable profiled zipper parts, and a plurality of projections that latch under the zipper parts to retain the slider on the zipper. The frame has three bridging members, a first opening disposed between the first and second bridging members, and a second opening disposed between the second and third bridging members, the plow being connected to and depending downward from the second bridging member.

Abstract: A reclosable package or bag having a slider-operated string zipper. The respective parts of the string zipper comprise a respective base strip and a respective set of profiled closure elements projecting from a front side of the base strip. The upper margins of the respective bag walls are joined to the backs of the respective base strips. The slider rides on the string zipper with the upper margins of the bag film being disposed between the zipper and the slider.

Abstract: Methods and apparatus for low-cost manufacture of reclosable packages having slider-operated zippers. One method of manufacture comprising the following steps: (a) joining film material to a back side of a first flangeless zipper strip having a first closure profile on its front side; (b) joining film material to a back side of a second flangeless zipper strip having a second closure profile on its front side, the first and second closure profiles of the first and second zipper strips being interlockable to form a string zipper assembly; and (c) loading a slider comprising a plow onto an open section of the string zipper assembly with the plow being inserted between the first and second flangeless zipper strips. Respective portions of the first and second portions of film are respectively disposed between the slider and the string zipper assembly when the slider is loaded.

Abstract: A reclosable package or bag having a mouth with a hermetic plastic zipper installed therein. The hermetic zipper has first and second interlockable profiled structures connected by a frangible connection and having no flanges. The package or bag is constructed such that the frangible connection resides on the product side of the zipper, i.e., the frangible connection extends inside the receptacle of the package or bag, when the package is in an unopened state, i.e., when the zipper is closed. Preferably, the first interlockable profiled structure has at least one male member with an expanded head and the second interlockable profiled structure has at least one female member with a groove for receiving the expanded head of a male member.
