This disclosure relates to infusion bags for infusible substance such as tea or herbs or the like for which separation of the infusible substance from liquid is desired. The disclosure also relates to a device which provides function of storing empty infusion bags in a container, and retrieving the empty bag individually from the container, holding and opening the retrieved bag for filling, and ejecting the filled bag for use. The infusion bags and device of the present invention is ideal for making hot tea or herbal beverages, and for other infusion needs in cooking where separation of the infused material from liquid is desired.

Disclosed is a method for manufacturing a stick-type tea bag, which includes (a) forming a part of a board to form a pair of holes symmetrically based on a virtual center line formed at the board, (b) disposing a jig, which has grooves at locations respectively corresponding to the pair of holes, below the board, (c) disposing a mesh member on the pair of holes to respectively cover the pair of holes, (d) attaching an edge of the mesh member to a part of the board adjacent to the holes by pushing an upper portion of the mesh member with a push rod, in a state in which the push rod is inserted into the groove, and (e) adhering inner sides of the board in a state in which the board is folded based on the center line with tea being interposed therein so that the tea is confined in a storage bag.

Provided is a process for thermoforming a gas and liquid permeable layer (10) of thermoplastic material having an average thickness of less than 1.0 mm, the process comprising the steps of bringing the layer of thermoplastic material, at a temperature below that required for thermoforming, into contact with a mould (16) at a temperature above that of a thermoforming temperature of the thermoplastic material; pressing the mould into contact with the layer of thermoplastic material, the contact between mould and thermoplastic material causing heat to transfer from the mould to the thermoplastic material and raising the temperature of the thermoplastic material to a thermoformable temperature; such pressing thereby causing thermoforming of the thermoplastic material to conform to the shape of the mould.

The present invention relates to a device for transporting ready-cut and filled hose pieces within a machine for producing bags filled with brewable material, having at least one transport wheel which includes, distributed over its circumference, a plurality of holders each holding the bag, wherein an insertion station in which one of said hose pieces is inserted into said holder in a radial direction to form a bag with at least one chamber between a head and a bottom of said bag, a label feeding station in which a label is fed to said head, a connecting station, in which a thread is connected to the label and/or the bag, and a removing station, in which the bag is removed from the transport wheel, are provided distributed in the circumferential direction around the transport wheel.

A biodegradable whole leaf pillow tea bag is provided, along with a system and method for manufacturing biodegradable whole leaf pillow tea bags. The method for manufacturing the whole leaf pillow tea bags includes the steps of providing a biodegradable infusion substrate having two opposing edge; creating a sleeve from the biodegradable infusion substrate by infusing the two opposing edges of the substrate together and closing the sleeve at its bottom; placing whole leaf tea in the bottom of the sleeve; vertically feeding the sleeve containing the whole leaf tea into a heat sealing machine that will, at predetermined intervals create heat seals across the sleeve to create pillow bags; cutting the pillow bags from one another across the heat seal. In one example, the biodegradable infusion substrate may contain hemp and/or the whole leaf tea may be infused with CBD oil or other supplements. The same method of manufacturing may be used to create a biodegradable pillow bag containing coffee.

A machine for manufacturing pouches containing a cohesionless material, including feed means for feeding the cohesionless material to a pick-up station, a transfer drum by which the material is picked up at the pick-up station and transferred to a release station, delivery means operating at the release station and by which portions of the material are delivered from the transfer drum through a duct toward a wrapping station at which the portions are sealed in pouches, and a mixer located at the pick-up station for performing a mixing action on the material at the pick-up station before the material is picked up by the transfer drum.

An over-wrapping envelope containing a filter bag for an infusion product, includes a sheet of over-wrapping paper folded in a U shape along a transversal axis around the filter bag to have two parts of over-wrapping material superposed on said filter bag, the sheet having two parallel longitudinal flaps, a bottom flap at the folding and a top flap parallel to the bottom flap, parallel first and second closing tracks formed by grooves along lateral edges of the longitudinal flaps of the folded sheet and where the first and second tracks are obtained by mechanical deformation of the two superposed parts of the sheet (2) at the respective longitudinal flaps; and a third closing track formed by grooves along the transversal top flap obtained by mechanical deformation of the two superposed parts of the sheet at the transversal top flap.

The present invention concerns a process for producing a container for the preparation of a beverage in a beverage preparation device, comprising the steps of: a. providing a water injection wall (3) of said, b. providing a beverage delivery wall (4) of said container, wherein at least one, preferably both, of said injection and delivery walls (3, 4) has a cup shape, c. placing a beverage ingredient body in said at least one cup shaped wall (4), d. sealing together edge portions (3A, 4A) of said injection and delivery walls (4, 3) in a sealing station, such as to form a chamber (1), wherein said sealing station comprise a housing element having a housing temperature (Th), wherein said body (2) is shaped and dimensioned such as not to completely fill said chamber (1), said process being characterized in that, after the sealing step, the container is cooled to a cooling temperature (Tc) being either: at least 15 C. lower than the temperature of the housing, orcomprised between 10 C. and +25 C.

A single-serve coffee package has an outer envelope having one folded edge and three heat-sealed edges, comprising 95% by weight materials that are compostable and demonstrate bio-degradability, a filter bag fully within the outer envelope, having one folded edge and sealed edges, forming a closed envelope having opposite sides, each side comprising one layer of filter material, fully compostable and biodegradable, the filter material exhibiting a plurality of openings through the material, enabling water to pass through, the openings having no dimension exceeding a minimum dimension, a volume of grains of ground coffee within the filter bag, dimensions of the grains precluding coffee grains passing through the openings through the filter material, and an atmosphere of gas within the outer envelope, enveloping the filter bag and the coffee grains, the gas inert relative to materials exposed within the outer envelope.
