A fin sealer and method to seal a radially outwardly directed fin of a tubular web structure by directing the fin through a nip between a first and a second fin sealing rollers while communicating heat to the fin through at least one of the fin sealing rollers is provided. The fin sealer is configured to maintain a nominal face-to-face relation between an outer annulus of the first fin sealing roller and an outer annulus of the second fin sealing roller with a flexible connection between a hub element of the second fin sealing roller with the outer annulus of the second fin sealing roller.

A repair system that includes a handheld device comprising a first extruder tip having an interior passageway extending between an inlet and a tip outlet, wherein the inlet is configured to receive a solid thermoplastic material and the tip outlet is configured to dispense a fluidic thermoplastic material; a nozzle surrounding the first extruder tip to form an annulus between an interior surface of the nozzle and an exterior surface of the first extruder tip; and a heater that is configured to heat the interior passageway of the first extruder tip such that the solid thermoplastic material becomes the fluidic thermoplastic material. In some embodiments, the repair system also includes a gas source in fluid communication with the annulus such that a skirt-shaped curtain of gas extends from the annulus and in a direction towards the tip outlet of the extruder tip.

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.

Multilayer Films have a first skin layer that is prepared from a high density polyethylene and a second skin layer (also referred to as the sealant layer) that is prepared from a linear low density polyethylene (LLDPE) having a density of from 0.90 to 0.92 g/cc and a Dilution Index, Yd, of greater than 0°. Seals can be prepared by placing two pieces of this film against each other such that the sealant layers are in contact with each other, then applying heat to at least one high density skin layer such that heat is transmitted/conducted through the multilayer film in a sufficient amount to melt the sealant layer and form a seal. The use of LLDPE having a Dilution Index of greater than 0° has been found to improve the sealing performance of multilayer films in comparison to multilayer films where the sealant layer is a conventional LLDPE having a Dilution Index of less than 0°.

The present invention relates to a device for making a pouch received in a wrapping, comprising a pouch making device which is adapted to produce a pouch containing brewable material in a water-permeable wrapping, and comprising a sealing station with two sealing jaws movable relative to each other for sealing the pouch in a wrapping formed by a wrapping material. This device is characterized in that it comprises a pouch handling device for removing the finished pouch from the pouch making device and a wrapping material handling device for handling the wrapping material during the U-shaped wrapping of the wrapping material, wherein the handling device and the wrapping material handling device are adapted such that the pouch held by the pouch handling device and the wrapping material held by the wrapping material handling device are introduced into the sealing station.

There are provided a synthetic resin joined body and a method of manufacturing the same, with which it is possible to secure both of sealing performance of a fluid passage and joint strength between synthetic resin parts, even if an area of a portion to be welded is reduced. The synthetic resin joined body includes: a baffle plate; an oil passage forming member which comes in contact with the baffle plate; an oil passage which is formed between the baffle plate and the oil passage forming member and through which lubricant flows; a sealing portion which is formed by welding the baffle plate and the oil passage forming member to each other on an outer side of the oil passage to seal a periphery of the oil passage; and a joint portion for joining the baffle plate and the oil passage forming member to each other.
