The invention is intended to solve the problem of squeezing and recycling of individual tea bags after their use, to enhance the aesthetic component of the process, as well as to be used as an advertising, information medium. In its original static state, the device has an elongated shape, presumably of a rectangular flat plate. After the device is folded in half, i.e. after the completion of its operation cycle, it acquires a different shape, presumably of a triangular, with four legs (the number is optional), fixing it to a surface, for example, a table. The used bag will be located inside the device, on any of its planes. Due to its low cost, a one-time and widespread use of the device is foreseen.

An overwrap envelope (7) containing a filter bag (1) for infusion products comprises a sheet (2) of overwrapping material folded into a U shape along its transversal axis (X) around the filter bag (1). The overwrap envelope (7) has two longitudinal sides (3, 4) and one transversal side (5) sealed by at least two sealing lines (6) which are uninterrupted along the longitudinal sides (3, 4) and along the transversal side (5). Each scaling line (6) is defined by two longitudinal stretches and one transversal stretch which are joined to obtain an uninterrupted shape and which form an uninterrupted perimeter seal.

The present invention relates to a device and a method for manufacturing a bag received in an envelope and containing a brewable material with a bag manufacturing means which is configured to manufacture a bag containing brewable material, and with a sealing station with a sealing jaw element and a counter-jaw element which act on the envelope from opposite sides to seal in the bag. The device is further developed for a reliable and safe manufacture of the packing unit consisting of a bag and an envelope by the sealing jaw element being fixed to a sealing jaw swivel arm at which a sealing jaw connecting rod is applied, and the counter-jaw element being fixed to a counter-jaw swivel arm at which a counter-jaw connecting rod is applied, and by the sealing jaw connecting rod and the counter-jaw connecting rod being each eccentrically connected to a common drive shaft of a servomotor. In the method according to the invention, the contact force between the sealing jaw element and the counter-jaw element is controlled via the torque of the servomotor actuating the sealing jaw element and/or the counter-jaw element.

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.

A Tea Display and Storage Device includes a front and back cover, a centralized spine with pages bound to it, a plurality of tea bag holders on each page to carry individual tea bags and a fastener to keep the Tea Display and Storage Device closed when not in use. The covers and the tea bag holders contain an absorbent layer to keep the tea bags fresh. Each tea bag holder can either be open to allow easy removal of tea bags, or be closed to seal the tea bag against the page. The seal on the tea holder can be a tongue and grove system, magnets or a type of adhesive strip. To aid in identification of the tea bag in each holder, the teabag holder can be clear or if the holder is opaque, a name tag can be attached to the holder.

A receptacle for a sodden beverage infusion pouch is disclosed herein. The receptacle for a sodden beverage infusion pouch includes a disposable sheet, and a disposable absorbent-barrier. The receptacle for a sodden beverage infusion pouch is useful for providing a means for no-mess disposal of the sodden beverage infusion pouch. In a preferred embodiment, the beverage infusion pouch may be a tea bag.

A filter-bag for liquid infusion products including a thermoformed body with filtration properties having an inner volume defined by a bottom, a mouth delimited on the perimeter by an upper flat edge, and a connecting wall between the bottom and the upper edge; the wall being provided with at least one rib extending from the bottom towards the upper edge in such a way as to define at least two chambers for containing corresponding infusion products separate from each other and included in the internal volume of the thermoformed body; a flat piece of non-thermoformable filter material, having transparency characteristics, and associated with the upper edge of the body for covering the opening and separating the chambers obtained in this way.

The cold-brewed tea beverage bottle includes a bottle cap and a bottle body; a tea container is arranged on an upper portion of the bottle body or the bottle cap; a retaining cap is mounted in the tea container in a clearance fit; a bottom end of the retaining cap is of a zigzag shape, which is just opposite to a seal sheet on a bottom portion of the tea container; a water outlet is formed on an upper portion of the retaining cap; a pushing rod is arranged on the tea container and in the bottle cap; the pushing rod and a force-exerting sealing cap both are in threaded connection with the bottle cap; by rotating the force-exerting sealing cap and pressing down the pushing rod, the retaining cap props against the seal sheet to open, and the tea leaves in the tea container fall into the bottle to soak.

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.

The present invention relates to water-soluble unit dose articles comprising cyclic diamines.
