A method of manufacturing an ink jet print head capable of bonding the printing element substrate to the support surface with high precision in a reduced period of time is provided. For this purpose, raised flat portions are formed in the support surface of the supporting member to provide in an adhesive layer between the printing element substrate and the supporting member a portion of the thermosetting adhesive that is thinner than others. After the relative positions of the printing element substrate and the supporting member are adjusted, the thin portions of the adhesive layer are hardened. This enables the printing element substrate to be bonded to the supporting member in a relatively short period of time. As a result, if there are undulations on the support surface, the printing element substrate can be bonded to the supporting member with high precision, improving the mass productivity of the print head.

A process for packaging a product arranged on a support comprising unrolling a film, moving the film to a packaging assembly defining at its inside a packaging chamber, progressively moving a number of supports inside the packaging chamber of the packaging assembly, closing the packaging chamber with the film sheets held above the respective support, optionally causing one or both of: a gas withdrawal from the hermetically closed packaging chamber and gas injection of a gas mixture of controlled composition, heat sealing the film to said support, wherein the heat sealing uses one or more heaters having heating surfaces which are heated for discrete and short time periods only. An apparatus for performing the above process is also disclosed.

A sealing plate for use with a packaging machine that integrates a seal formed indicia into a portion of a package seal. A package having a seal formed indicia integrated into the package seal, which when the package is opened undergoes undergo a visual transformation, and a method of making the same.

A tamper evident card package includes a first portion comprising plastic polymer and defining a cavity extending from a base surface of the first portion. A second portion comprises a flat sheet of plastic polymer joined to the first at a seal extending around an entirety of a perimeter of the tamper evident card package, where the first portion and the second portion form a unitary structure at the seal. An insert contained between the first portion and the second portion includes a point-of-sale activated card and machine readable activation information for the point-of-sale activated card from an exterior of the tamper evident card package.

The present disclosure provides a method for detecting thermal sealing defects of a container during its transportation along a process line. The method is particularly suitable for containers caped with a cap liner and sealed with an inner seal. The method makes use of a high frequency heat (e.g. by a high frequency heat induction unit) to cause eddy current in the inner seal after which there is sensing by an IR imager of radiation emitted from the conductive innerseal to generate sensed IR image data indicative of the sensed radiation. The sensing is characterized by at least one of (i) a time window of a sensing session of between 50 msec to 300 msec during which said container is being transported through the FOV; and (ii) a sensing range of a wavelength spectrum region from 2 μm to 6 μm. The IR data is then processed so as to generate output data indicative of the presence or absence of at least one defect in the sealing of the container by said innerseal.

A polar functional group is added onto a surface of a metallic member. A resin member contains an adhesive functional group. The adhesive functional group and the polar functional group attract each other. A method for joining the metallic member and the resin member to each other includes: heating a junction between the metallic member and the resin member while pressing the metallic member and the resin member against each other with a first load; maintaining temperature of the junction higher than melting temperature of a resin that structures the resin member while pressing the metallic member and the resin member with each other with a second load smaller than the first load; and cooling the junction to temperature lower than the melting temperature while pressing the metallic member and the resin member against each other with a third load larger than the second load.

A patterned thermoplastic elastomer (TPE) film for fabricating a liquid-filled blister, has a blister-sized cavity in fluid communication with a microfluidic channel via a gating region. The gating region is defined by a relief pattern that has at least one of the following: at least 5 separate compartments defined by respective recesses in the first side, each of the recesses bounded by walls that separate the compartments from each other, the recess, or the channel; at least 5 walls defined by the patterning of the first side, the walls separating a plurality of compartments from each other, the recess, or the channel, wherein the walls have a mean thickness that is less than a mean height, and each pair of walls has a mean separation greater than twice the mean thickness; an array of separate compartments bounded by walls defined by the patterning of the first side that collectively define a polygonal regular planar tiling with at least 50% of the surface area of the gating region being open spaces; and a focusing region in fluid communication with the cavity, and a seal region having at least one wall defined by patterning of the film, wherein the at least one wall separates the focusing region from the seal region, and a shape of the at least one wall tapers the focusing region towards the seal region.

Liner having an induction heat sealable layer for sealing to a rim of a container, and a pull tab for ease of removal of the liner from the container rim. A folded insert disposed between multilayer upper and lower components, has a heat bondable polyolefin layer that is thermally laminated to polyolefin layers of the upper and lower components, forming a pull tab between the integrated polyolefin layers. The resulting composite resists delamination and can be formed in a single thermal lamination step, avoiding the multiple lamination steps, associated high equipment costs, and complex layer constructions of the prior art.
