An external reinforcing strap system for a bulk material cargo container liner comprises a plurality of vertically spaced, horizontally oriented reinforcing straps, or a plurality of horizontally spaced, vertically oriented reinforcing straps and a plurality of vertically spaced, horizontally oriented reinforcing straps, to have their tension levels individually adjusted in an independent manner in order to provide selected sections of the external reinforcing strapping system with requisites amount of tension. In addition, a substantially U-shaped reinforcing gusset system is also disclosed which provides the necessary reinforcement for the rear wall member of the bulk material cargo container liner but with a simplified structure effectively eliminating the aforenoted strapping system.

A method for forming a longitudinal bend in a strap in a strapping machine by forming a pre-bend in the strap between a first wheel and a second wheel having cooperating, non-planar strap contact surfaces and subsequently forming the longitudinal bend in the strap between the second wheel and a third wheel having cooperating non-planar strap contact surfaces.

Modular strap feed head with forming wheels

A strap having increased column stiffness includes a leading edge and a trailing edge forming a length of the strap, a first outer edge and second outer edge defining a width of the strap, and a first side and a second side defining a thickness of the strap. A crush region is formed in the first or second side, between and generally parallel to the first and second outer edges. The crush region is defined by a thickness that is less than the thickness of the strap adjacent to the crush region. The crush region forms a line along which a bend may be formed in the strap. The bend increases the column stiffness of the strap at least about 67 percent over that of a comparable flat strap. The bend defines an acute angle and an obtuse angle in the strap as viewed in cross-section.

Strap with improved column stiffness

A strap forming assembly for a strapping machine includes a first forming wheel having a circumferential groove formed in a rim thereof and a second forming wheel cooperating with the first forming wheel and having a mating a circumferential crown extending therefrom. The first and second forming wheels cooperate to define a forming wheel nip therebetween. The forming wheel nip is non-planar. Strapping material fed into the forming wheel nip is permanently, longitudinally deformed.

A nozzle head for dispensing sealant within a gap is provided. The nozzle head includes, but is not limited to, a body section and a port connected with the body section. The body section forms a primary channel through which sealant is dispensed. The primary channel forms an entrance through which sealant enters the body section and an exit through which sealant is dispensed from the nozzle. The port is connected with the body section and surrounds the exit. The port forms a chamber having a tip portion opposed to a rear opening. The chamber forms an angled path from the tip portion to the rear opening to trap and guide excess sealant within the chamber to the rear opening.

Methods of making slide-zippered reclosable packages are provided. In one embodiment, a pair of opposing film extensions are provided on each package between which a zipper and slider are attached. In another embodiment, sliders are inserted on to zippered packages output from a form-fill-seal machine or the like. In yet another embodiment, during package formation a reclosable zipper is sealed to each package and then a slider is inserted on to the zipper. In yet another embodiment, during package formation a reclosable zipper is sealed to each package and a slider is inserted on to each zipper, either before or after zipper sealing.

A reclosable vacuum storage bag that can be hermetically sealed by flat resealable means that extend across the full width of the bag. The flat resealable means are designed to provide a barrier to prevent ambient air from leaking into the evacuated interior volume of the bag. The storage bag is also provided with a plastic zipper. The flat resealable means can be arranged on the product side of the zipper, on the user side of the zipper, or in between two zippers installed in the storage bag.

A bulk material cargo container liner system comprises an inflatable bulk material cargo container liner which has at least one vacuum discharge tube member disposed internally within the bulk material cargo container liner and extending along the longitudinal extent thereof for discharging bulk cargo material outwardly from the bulk material cargo container liner, and at least one inflatable air bag component for conducting the bulk material, disposed within the bulk material cargo container, toward the vacuum discharge tube member.

A bulk container liner assembly for use in conjunction with a bulk material cargo container comprises structure incorporated therein such that restraint forces are impressed upon or transmitted to the back or rear wall member of the bulk material cargo container liner, along linearly seamed loci, so as to effectively prevent the back or rear wall member of the bulk material cargo container liner from experiencing or undergoing any outward bulging thereof under the influence of the hydrostatic head load forces generated internally within the bulk material cargo container liner as a result of the charging of bulk cargo material into the interior portion of the bulk material cargo container liner.

A new and improved thermal type bulkhead assembly comprises a pair of new and improved thermal type bulkhead members which are adapted to be adjustably positioned with respect to each other in an overlapped mode in the widthwise direction whereby oppositely disposed side edge portions of the pair of bulkhead members can effectively engage the oppositely disposed interior side walls of the refrigerated cargo container, while upper sections of the bulkhead members can flexibly engage the ceiling portion of the refrigerated cargo container. In this manner, the lateral extent or width dimension x of the thermal type bulkhead assembly, as well as the vertical extent or height dimension y of the thermal type bulkhead assembly, can be adjustably varied whereby the thermal type bulkhead assembly of the present invention is effectively universal in structure so as to be capable of being utilized within different refrigerated cargo containers characterized by different internal width and height dimensions.

A zipper strip for a reclosable bag or package includes a male interlocking profile and a female interlocking profile. The male interlocking profile includes a male interlocking member and a male web coextruded therewith. In like manner, the female interlocking profile includes a female interlocking member and a female web. The male interlocking member snappingly engages into the female interlocking member to join the profiles to one another. One of the male and female webs is wider than the other in at least one of two directions from the male and female interlocking members, the greater width being represented by at least one flange extending widthwise beyond the other web. The zipper strip is designed to be attached to thermoplastic sheet material by sealing the at least one flange thereto without sealing the male and female webs to each other. Methods for securing the zipper strip to thermoplastic sheet material, and for making packages on a horizontal form-fill-and-seal machine, are also disclosed.

An ultrasonic welding assembly comprising a horn, an anvil and an anvil cover. The horn comprises a generally T-shaped flattening surface and a rail projecting forward of the flattening surface. The rail is shaped to serve as a dam for flowing thermoplastic zipper material during stomping of slider end stops. The horn further comprises a plurality of vertical energy directors designed to direct ultrasonic energy into the mass of zipper material and deflect flowing zipper material toward the dam. The horn further comprises first and second recesses located on opposite sides of a stem of the T-shaped flattening surface. The anvil cover overlies opposing portions of the anvil and comprises a T-shaped cutout. The T-shaped flattening surface of the horn fits in the T-shaped cutout of the anvil cover. The resulting zipper has slider end stops located at opposing ends. Each end stop comprises flattened zipper material having a plurality of spaced indentations, the indentations being formed by the energy directors during stomping. The zipper can be pre-heated prior to ultrasonic stomping. A flange of the zipper can be cooled by fluid during ultrasonic stomping of the zipper parts.
