Resin joined body and method for manufacturing same

A method for producing a resin joined body in which a specific region L1 of a welding portion of a second resin member (21) is provided to form a low-laser-light-transmissible portion, and the low-laser-light-transmissible portion has a laser light transmissibility lower than that of a region of the welding portion other than the specific region L1. Welding is carried out so that a portion between points S2 and F2, serving as a weld overlap portion (112), is present in the specific region L1 forming the low-laser-light-transmissible portion. Also disclosed is a resin joined body.

Lidding device

Embodiments of the present invention provide a three-panel lidding device used to seal a food container. Such devices are particularly useful for covering and sealing a plastic food container, eliminating (or diminishing) the need for an outer carton and the clear film membrane that traditionally covers a food container. The lidding device may contain all brand identifiers, product messaging, ingredient list, instructions (e.g., opening and cooking) printed directly on the device. The device may also allow for venting of the food container during cooking and may then be removed for serving. The device may further provide a foot panel that allows the food product container/lidding device to sit upright, enhancing store front and freezer display options.

Heat sealing thru food contaminants

A container is provided with a flange defining a container opening that may help expunge food product as the film and seal head comes down on the container flange. The flange of the container opening has a predetermined angle. The container flange with its sealing surface generally deflects or angularly pivots when sealed with the film during the sealing process. The container flange and film may push product contamination from the sealing surfaces inwardly into the container. The flange may be continuous about the periphery of the container opening.

FORMABLE FILMS, LAMINATE STRUCTURES, AND RELATED METHODS

Embodiments of the disclosure relate to a blister package having a laminate structure that is heat-sealable to a lacquer layer on strain-hardened aluminum foil. The blister package includes a lid layer comprising a strain-hardened aluminum foil, a lacquer layer on a sealing surface of the strain-hardened aluminum foil and a laminate structure sealed directly to the lacquer layer. The laminate structure includes a multilayer film and a plurality of wells formed therethrough. The multilayer film includes a first formable layer of a thermoplastic material and a sealing layer of a copolyester material. The sealing layer overlies the first formable layer and has an outer surface opposite the first formable layer. The sealing layer has crystallinity from 5% to 20% as measured by differential scanning calorimetry (DSC). The outer surface of the sealing layer is sealed directly against the lacquer layer.

SEALING SUPPORTED BY PRESSURIZED AIR

A method of closing a packaging tray comprises arranging a packaging tray between a lower tool and an upper tool of a sealing station, positioning a cover film above the packaging tray between the lower tool and the upper tool, and pressing together the cover film and the packaging tray by a lower sealing surface of the lower tool and an upper sealing surface of the upper tool cooperating with the lower sealing surface. During the pressing together, a connection is established between the cover film and the packaging tray along a sealing seam. While the cover film and the packaging tray are being pressed together, an overpressure is locally generated by supplying pressurized gas from a pressurized-gas source, the overpressure cooperating as a counterpressure with the lower sealing surface or with the upper sealing surface so as to press the cover film and the packaging tray together.

Method for determining whether a sealing area of a primary packaging container for an ophthalmic lens is unacceptable for properly sealing a foil thereto

A method for determining whether a sealing area of a primary packaging container for an ophthalmic lens is unacceptable for properly sealing a foil to the sealing area is disclosed. The method involves comparing the temperature of an infrared image of the sealing area to a reference temperature to determine if the difference in temperature exceeds a predetermined threshold.

A shaped article, a method for making it, and its use. The shaped article is formed from flat fiber material and has a bottom (2), a body (4), and an opening, which is surrounded by a circumferential flange (6). The shaped article (1) comprises a flange stabilizer (10) attached to the second flat side (18) of the flange (6) facing the bottom (2). The flange stabilizer (10) is disc-shaped and has an inner contour (12) corresponding to the desired cross-sectional shape of the shaped article (1) in the region of the opening and can be slipped over the body (4) in the region of the bottom (2) and up to the flange (6). The flat sides (16, 18) of the flange stabilizer (10) extend essentially parallel to the flange (6), defining and stabilizing the cross-sectional shape of the body (4) in the region of the opening and the flange.

A method of making a flowcell includes bonding a first surface of an organic solid support to a surface of a first inorganic solid support via a first bonding layer, wherein the organic solid support includes a plurality of elongated cutouts. The method further includes bonding a surface of a second inorganic solid support to a second surface of the organic solid support via a second bonding layer, so as to form the flowcell. The formed flowcell includes a plurality of channels defined by the surface of the first inorganic solid support, the surface of the second inorganic solid support, and walls of the elongated cutouts.

SYSTEMS AND METHODS FOR THE HIGH-SPEED APPLICATION OF PAPER-BASED END CLOSURES ON COMPOSITE CONTAINERS
20210371140 · 2021-12-02 ·

A system for assembling a container and closure comprising an expanding collet which has a plurality of pivoting collet segments, each configured to simultaneously pivot radially outward about a pivot point and comprising. The collet comprises a lip that is engagable with the rim of the open end of the container and an angled tip positioned radially inward from the lip and shaped to press a countersink portion of the closure against an interior wall of the container as the collet segments pivot radially outward. As the container and the chuck are brought together, the rim engages with the lips of the collet segments and causes the angled tips of the collet segments to pivot outward toward the interior wall of the container, thereby pushing the countersink portion of the closure against the interior wall of the container.
