The present invention also relates to a cellulosic laminar element and to a disposable foods and/or drinks service packaging and containers obtained by means of the method of the present invention.

Method and Apparatus for Folding and Opening-Up Wipes

Apparatus is provided for manufacturing a wipe in a three dimensional form out of an essentially flat piece of material. The apparatus produces a blank (12) of essentially flat planar form with a pleat folded on each side. The folded blanks are fed by a conveyor belt (21) to an opening station (22). The opening station comprises a pair of movable pinch rollers (34, 35) which selectively grab individual blanks from the conveyor belt and feed them via belts (32, 33) to a pair of counter-rotating drums (30, 31). The blanks are ejected from the drums, which partially opens them up in the process. The partially open blanks are fed onto a shaped former (37), where the final process of forming the wipe into its chosen three dimensional form is completed.

PAPER PICTURE FRAME, BLANK THEREFOR, AND METHOD FOR HOLDING A PICTURE IN A PAPER PICTURE FRAME SUPPORTED ON A PAPER STAND

The present application relates to a paper picture frame including a central rectangular portion and four rectangular tubular frame sections extending along four margins of the central rectangular portion at the rear surface thereof. The paper picture frame further includes a paper stand for holding the paper picture frame on a flat surface. The paper stand may be in the form of a triangular tubular structure formed by a base panel, a first side panel, and a support panel. A second side panel extends from the base panel over the support panel, and has a terminating end extending beyond the first side panel. A blank for forming the paper picture frame and a method for holding a picture in the paper picture frame supported on the paper stand are also disclosed.

TUBE FILTER PRODUCTION DEVICE AND TUBE FILTER PRODUCTION METHOD

According to embodiments of the present invention, there is provided a tube filter production device including a tube filter exterior forming case into which one or more filter tows are introduced and from which a tubular rod formed from the one or more filter tows is discharged, a tube filter forming bar extending in an inner region of the tube filter exterior forming case in order to form a hollow of the tubular rod, and a steam chamber having at least one steam nozzle in communication with the inner region of the tube filter exterior forming case and configured to supply steam to the one or more filter tows through the steam nozzle, wherein the tube filter forming bar has a duct extending in a longitudinal direction of the tube filter forming bar and a flavoring nozzle formed in a downstream end region of the tube filter forming bar to deliver a flavoring liquid or a moisturizing liquid supplied through the duct to the hollow of the tubular rod.

Method for manufacturing paper straw

The present invention relates to a method for manufacturing a paper straw, the method comprising: a paper roll transmission step, a paper strip heating step, a bonding and shaping step and a cutting step. Wherein, a plurality of raw paper rolls face a connection position jointly to transmit a raw paper strip, the raw paper strip includes a paper material and a dry hot-melt adhesive. The dry hot-melt adhesive of the raw paper rolls is heated for changing into flow hot-melt adhesive. Then the raw paper rolls is transmitted to the connection position for rolling jointly, and the flow hot-melt adhesives are bounded on another raw paper strip to form a pipe. Finally, the pipe is cut to form at least one paper straw after the pipe exceeds a setting length. The present invention uses dry adhesive to manufacture paper straw, without the excessive glue problem and mold phenomenon of the traditional wet bonding method as well as without an extra dry fixing step of traditional manufacture process, so the productivity will be raised significantly, and the defect rate will be reduced.

COATED PAPERBOARD CONTAINER, METHOD OF MANUFACTURING A COATED PAPERBOARD CONTAINER, AND CUP BOTTOM FORMING APPARATUS

A method of manufacturing a coated paperboard container includes: providing a coated paperboard bottom blank, the coated paperboard bottom blank comprising a paperboard substrate and a first barrier coating layer on a first outermost surface of the paperboard substrate; heating the coated paperboard bottom blank; shaping the heated coated paperboard bottom blank, thereby forming a peripheral skirt portion about a periphery of a bottom wall portion of the coated paperboard bottom blank; and sealing a coated paperboard sidewall to the first barrier coating layer of the peripheral skirt portion.

Apparatus for the manual or machine-made production of a tube-like packaging material and packing station

An apparatus for the manual/automatic production of a tube-like packaging material can include a guiding chute with an opening for ejecting the packaging material from a roll arranged in the ejection position, wherein the guiding chute has an inner contour narrowing towards an opening in an ejection direction, a primary seating for at least partly circumferentially gripping the first roll and for holding the first roll in the ejection position, and at least one secondary seating for receiving of at least a second roll for reloading the apparatus, wherein the secondary seating is movable with a second roll between a passive position in which the second roll is outside an ejection position and an active position in which the second roll is arranged in the ejection position or is displaceable from the secondary seating into the primary seating under (e.g. exclusively under) the impact of gravity.

Collapsible article comprising combinations and multiplications of foldable sections
11814214 · 2023-11-14 · ·

A collapsible article comprising a plurality of foldably interconnected foldable sections/modules. The foldable sections can be part of cylindrical or conical surfaces. They can also be in the form of closing sections. When the foldable sections are part of tubular surfaces, either cylindrical or conical, they consist of four polygonal surface segments. The polygonal segments are curved/round in unfolded state and have a flat or approximately flat shape in partly folded and folded states. The folding process usually involves an abrupt transition between the unfolded and folded positions which makes the unfolded article almost as stable as non-foldable equivalents. The folding process usually requires application of force on the edges that form valley creases during folding.
