The present invention is directed to a method forming a bottom-gusseted package, wherein each package includes an inwardly-extending, pleat-like gusset at the bottom of the package. To permit heat-sealing formation of each package, the sleeve from which each gusset is formed comprises a lamination of two differing polymeric materials, so that only an exterior surface of each sleeve exhibits the desired heat-sealing characteristics. To facilitate package formation, the sleeves from which the bottom gussets are formed are maintained in a temporarily closed or sealed configuration during package formation by providing a preferably frangible bond or seal at the edge of each sleeve. This result is preferably achieved by folding the laminate material, and temporarily sealing or joining an outer layer of the laminate material from which gusset is formed, while an inner layer is maintained in an unsealed condition.

A counter-element for processing a material by means of ultrasound, the counter-element having a sealing surface, the sealing surface having a welding portion which is at least partially concavely curved. The sealing surface has a feed-in portion which is arranged adjoining the weld portion and is either not curved or is concavely curved with a radius of curvature that is larger than the radius of curvature of the welding portion.

A sealing tool includes an anvil and a horn, at least one of which includes a sealing surface having a gusset sealing section and a zipper sealing section, each configured differently than the other. The gusset sealing section includes a plurality of sealing beads including a gusset section barrier sealing bead having a first height and a protective sealing bead having a second height, the second height being smaller than the first height. The zipper sealing section includes a zipper section barrier sealing bead extending and a tapered section adjacent to the zipper section sealing bead, the tapered section tapering from a larger height adjacent to the zipper section sealing bead to a smaller height as a distance away from the zipper section sealing bead increases.

The present invention relates to a method for portion-packing of an oral pouched snuff product (1, 1). The method comprises a) supplying and advancing a tubular web (19, 19, 19) of packaging material enveloping a continuous feed (23, 23, 23a, 23b) of filling material in a direction of travel (L), b) forming transverse seals (39) in the tubular web across the continuous feed of filling material by means of ultrasonic welding, the transverse seals extending in a transverse direction (T) being perpendicular to the direction of travel. The present invention further relates to an arrangement (17, 17, 17) for portion-packing of an oral pouched snuff product.

The first electrode section (7a) and the second electrode section (7b) are formed such that the outer portion connected to the upper portion of the heating section (6) is thinner than the inner portion connected to the lower portion of the heating section (6). The heating section (6) and the first electrode section (7a) are interconnected by an R-shaped first connecting portion (21). The inner circumferential sloping surface of the heating section (6) and the second electrode section (7b) are interconnected by an R-shaped second connecting portion (22). The first and second connecting portions (21)(22) are formed such that R becomes larger from the upper end to the lower end, where the upper portion is thin and the lower portion is thick. The thickness of an intermediate portion (6b) is smaller than the thicknesses of the first and second connecting portions (21)(22).

A method and a machine for realizing containers, including at least steps of impressing a shape in relief on a sheet of deformable material, enveloping the sheet about itself and reciprocally joining lateral flaps thereof in order to form a tubular blank, and closing a bottom end of the tubular blank.

Provided is a thermal caulking method of melting, at one time, a plurality of bosses 33 of a second member 30 protruding toward an inner circumferential surface of a conical hollow portion 11 of a first member 10 while being fitted to a plurality of holes 132 provided in the inner circumferential surface of the hollow portion 11 of the first member 10 having the substantially conical hollow portion 11 so that the plurality of bosses are joined to the first member 10, in which the plurality of bosses 33 are melted at one time by using a heat chip 51 having a continuous shape in the circumferential direction of the hollow portion 11 along the inner circumferential surface and are joined to the first member 10 while the adjacent melted bosses 33 are connected to each other.

The first electrode section (7a) and the second electrode section (7b) are formed such that the outer portion connected to the upper portion of the heating section (6) is thinner than the inner portion connected to the lower portion of the heating section (6). The heating section (6) and the first electrode section (7a) are interconnected by an R-shaped first connecting portion (21). The inner circumferential sloping surface of the heating section (6) and the second electrode section (7b) are interconnected by an R-shaped second connecting portion (22). The first and second connecting portions (21)(22) are formed such that R becomes larger from the upper end to the lower end, where the upper portion is thin and the lower portion is thick. The thickness of an intermediate portion (6b) is smaller than the thicknesses of the first and second connecting portions (21)(22).

An induction sealing device for heat sealing packaging material for producing sealed packages of pourable food products, the sealing device comprising: an inductor configured to induce a current in the packaging material, the inductor comprising conductor elements; a polymer insert holding the conductor elements; and a supporting body holding the polymer insert; wherein the polymer insert comprises a polymer matrix into which graphene particles are dispersed.

The present invention relates to a sealing device (1, 101, 201) for sealing a packaging material (7, 107) enclosing a filling material (29) to provide portion-packed oral pouched snuff products (43). The sealing device comprises an anvil (3, 103, 203) with a first operation surface (11, 111, 211) and a sonotrode (5, 105, 205) with a second operation surface (13, 113), the anvil and the sonotrode being arranged to allow passage of the packaging material therebetween, the second operation surface being located opposite the first operation surface during operation of the sealing device. The first and second operation surfaces are arranged to weld a first portion (7a, 107a) of the packaging material to a second portion (7b, 107b) of the packaging material. At least one of the first or second operation surfaces comprises a first welding surface (11a, 111a) defining a first extension plane and a second welding surface (11b, 111b) defining a second extension plane, which has a different orientation than the first extension plane. The first and second welding surfaces are partly delimited by a cutting edge (15, 115, 215) having an extension direction along the first and second welding surfaces, such that the cutting edge separates the first welding surface from the second welding surface. The present invention further relates to an arrangement (19) for manufacturing of portion-packed oral pouched snuff products, which arrangement comprises such a sealing device. The present invention also relates to a method for portion-packing of an oral pouched snuff product.
