The present disclosure relates to an oral pouched snuff product comprising a filling material and a saliva-permeable pouch enclosing the filling material, the oral pouched snuff product having a longitudinal direction and a transverse direction perpendicular to said longitudinal direction, the saliva-permeable pouch comprising a first elongated seal and a second elongated seal, each of said first and second elongated seals having a seal length extending along the transverse direction of the product and a seal width extending along the longitudinal direction of the product, wherein the seal width of said at least one elongated seal being equal to or less than 2 mm, such as within the range of from 0.1 mm to 2 mm or from 0.1 mm to 1 mm or from 0.1 mm to 0.5 mm. There is also provided a container having a base and a detachable lid together providing an interior container space in which a plurality of these oral pouched snuff products is contained.

An apparatus for sealing the top of a package for a food product is disclosed. The apparatus comprises a pair of oppositely disposed first and second sealing jaws configured for reversibly engaging each other over the top of the package, at least one wedge on the first sealing jaw configured for contacting a first top portion of the package to form a first gable panel, a key on the second sealing jaw configured for contacting a second top portion of the package to form a second gable panel, at least one lug on the key configured for reducing skewing of the package prior to sealing, and a rubber dolly on either the first or the second sealing jaw, the rubber dolly and the opposing sealing jaw being configured to form and seal a fin between the rubber dolly and the opposing sealing jaw thereby sealing the top of the package. A system for forming, filling, and sealing a package containing a food product comprising the apparatus is also disclosed.

A plastic container and a method for producing a plastic container for liquids, in particular an inner container for transport and storage containers for liquids comprising an outer jacket made of latticework or of sheet metal material and a pallet-type understructure, the plastic container being realized as a blow-molded body by blow molding from a tubular preform in a blow mold and having a container socket for connecting a container fitting in a fitting connecting area of a container wall, the container socket being provided with a container opening and being connected to a connecting flange of the container fitting via a welded joint, wherein the container wall has an inner layer made of a first plastic material and an outer layer made of a second plastic material, and the container socket has a longitudinal cross section widening toward the container opening in such a manner that an end face of the container socket is formed at least in part by an inner layer segment disposed opposite the outer layer, and a welding contact surface of the container socket is formed by the inner layer segment.

A process for welding profiles (1) of a thermoplastic or thermoplastic elastomer to a top layer (3) of a belt (2), such as a conveyor belt, also being made of a thermoplastic or thermoplastic elastomer. The process uses thermal impulse welding and applies the welding heat onto the surface (21) of the belt (2) which is opposite to the top layer (3). The process is in particular suited for welding TPO profiles to TPO top layers.

The present invention discloses a heat fusing device for a smart trash receptacle, including: a heating wire for fusion-cutting and thermally sealing an open end of a trash bag, the heating wire being connected to a heat-fusing circuit; a base having heat-resistant and insulating properties, the base having a first end surface on which the heating wire is arranged; and a control mechanism communicatively coupled to the heat-fusing circuit for control thereof. The present invention also discloses a smart trash receptacle incorporating the heat fusing device and a method for controlling a heat fusing temperature. With the present invention, during automatic bagging by the smart trash receptacle, good contact between the heating wire and the trash bag can be ensured while preventing adhesion of the trash bag. This results in improved sealing quality and enables the fulfillment of two tasks, i.e., thermoplastic sealing and thermal fusion-cutting, in the same action of the heat fusing device. As a result, higher automatic bagging quality and reliability are obtainable at lower bagging control difficulty and reduced bagging cost. Moreover, control in the system is simplified, and the stability and reliability of the system are increased.

A system for consolidating materials, comprising a sonotrode configured to direct ultrasonic energy into materials to be consolidated, wherein the materials to be consolidated have both a glass transition temperature and a melting temperature; a non-rigid consolidating material in proximity to the sonotrode, wherein the non-rigid consolidating material and sonotrode define a region therebetween for receiving the materials to be consolidated, and wherein the non-rigid consolidating material has a glass transition temperature that is higher than the glass transition temperature of the materials to be consolidated and a melting temperature that is higher than the melting temperature of the materials to be consolidated.

A device for manufacturing a battery cell according to one embodiment of the present disclosure includes a sealing tool that forms a sealing part on the outer peripheral surface of a battery case to which an electrode assembly is mounted, wherein the sealing tool comprises a sealing surface that is brought into contact with the outer peripheral surface of the battery case, and wherein the sealing surface comprises a central surface and an inclined surface formed on at least one side of the central surface.

Methods of manufacturing and fixtures for manufacturing containers, particularly for holding cosmetic products, using thin-walled tubes. One end of a container may be formed using an integral process, such as insert molding, while the other end of the container is formed using assembly steps, such as welding, to form a completed cosmetics container from a thin-walled tube.
