Provided is a laser welded body which can be manufactured without undergoing complicated steps and maintain the characteristics of a resin contained in a resin member, which exhibits high welding strength even when scanned with a laser beam at a high speed, and which can be manufactured at high production efficiency. The laser welded body 10 comprises a first resin member 1 which is a laser-irradiated subject which contains a thermoplastic resin and nigrosine sulfate and has an absorbance a.sub.1 of 0.09 to 0.9; and a second resin member 2 which contains a thermoplastic resin as the same kind as or different kind from the thermoplastic resin and a laser beam absorbent, and has an absorbance a.sub.2 of 3.0 to 15, wherein the first resin member 1 and the second resin member 2 are laser-welded at a part at which the both resin members are overlapped and/or butted.

A substantially paper-based composite container for an off-gassing product includes a paperboard can body having a substantially gas-impervious liner attached to an inner surface thereof, and a pair of substantially paper-based end closures attached to the opposite ends of the can body, each end closure defining a generally cylindrical sealing panel in contact with an inner surface of the can body. Heat-sealable materials are disposed on opposing surfaces of the sealing panel and can body. The sealing panels of the end closures are attached to the can body by heat seals. The heat seal for at least one of the end closures is discontinuous such that at least one vent channel extends through the heat seal so as to establish fluid communication between an interior of the composite container and the environment outside the composite container. The at least one vent channel is operable to vent excess gas pressure from the interior of the container.

A honeycomb sandwich sheet or panel, based on thermoplastic polypropylene, includes a structure having two flat outer films, at the top and bottom, welded to at least two inner or central thermoformed blister films, repeated in a regular and continuous pattern, wherein the at least two inner thermoformed films are welded to each other.

A contact lens package includes a first package layer, a second package layer, a lens receiving area defined between the first and second package layers, and first and second seal portions. The first seal portion extends around a first portion of the lens receiving area. The second seal portion extends around a second portion of the lens receiving area. The second seal portion has different sealing properties than the first seal portion. The first seal portion may include a releasable seal between the first and second package layers, and the second seal portion may include a permanent seal between the first and second package layers.

This method for producing a packaged food product portion includes the following steps: providing a cup defining an inner area for receiving the food product; cold pouring, at a temperature below 50° C., the food product into the receiving area of the cup; covering the food product using a thermally insulating lid arranged such that thermally conducting flaps of the cup extend toward the outside of the lid after the covering step; folding the flaps on an outer face of the lid opposite the receiving area; and heat-sealing the flaps on the outer face.

A battery includes a battery element, a housing body, and a valve device. The housing body houses the battery element. The valve device is in communication with the inside of the housing body. Heat-sealable resin layers face each other in a peripheral edge portion of the housing body. A joined edge portion in which the mutually facing heat-sealable resin layers are fused together is formed in the peripheral edge portion of the housing body. The valve device is configured to reduce an internal pressure of the housing body if the internal pressure is increased due to gas generated in the housing body. The valve device includes a first portion that is located on an outer side of an edge of the joined edge portion and a second portion that is sandwiched between the heat-sealable resin layers in the joined edge portion.

Medicated starch-based powder formulations are packaged to ensure the medication remains stable for a desired shelf life. The medicated starch-based powder formulation may be packaged in a sealed container so as to maintain medicament functionality for at least one year. The container may be fabricated and/or lined with a low permeability coefficient and sealed with a foil heat induction seal liner. The container may be treated with a media to alter the surface properties of the container to increase the integrity of the container. The medicated starch-based powder formulation may include cornstarch and menthol.

Provided is a laser welded body which can be integrated through a laser-welding step without undergoing complicated steps even through use of the same or difference resin members each other, which has excellent welding strength between the resin members, which maintains the characteristics of a resin contained in the resin member and which exhibits the high welding strength by improving meltability of the resin members yet under a laser-welding condition of a medium and high scan speed. A laser welded body comprises a resin member(s) which contains a thermoplastic resin and nigrosine sulfate having a sulfate ion concentration of 0.3 to 5.0% by mass and has an absorbance a of 0.09 to 0.9, an adjoined part where the resin member(s) is overlapped and/or butted, and at least a part of the adjoined part is laser-welded.

A heat plate lock assembly for a heat scaling machine may include clamp plates mounted on either side of a heater assembly that are movable relative to the heater assembly and engage and support a heat plate beneath a heater platen of the heater assembly. Lift arms may be mounted to and movable relative to the heater assembly, and operatively connected to the clamp plates so that movement of the lift arms causes movement of the clamp plates relative to the heater assembly. In an open position, the heat plate can be inserted between and removed from between the clamp plates. In a closed position, the clamp plates move the heat plate into contact with the heater platen and a lock mechanism engages the heater assembly to retain the heat plate lock assembly in the closed position.

Systems, apparatuses, and methods to seal a container are provided. An apparatus for securing a film to a container includes a body portion to house film and a sealing portion. The sealing portion includes a loading zone to receive a portion of film from the body portion and an aperture to receive a top portion of the container and the portion of the film therethrough to enable positioning within a sealing volume. A plurality of near-infrared light emitting diodes (NIR LEDs) face toward and at least partially surround the top portion of the container when positioned within the sealing volume. A controller is configured to receive sensor input from a sensor indicating that the top portion of the container is within the sealing volume and cause, in response thereto, activation of the plurality of NIR LEDs to secure the portion of the film to the top portion of the container.
