The present invention relates to an expandable infusion packet (1, 5), wherein the infusion packet is in a permanently compressed state in the absence of water and converts to an expanded state in the presence of water.

The present disclosure provides various kinds of coffee drinks such as espresso using compressed coffee bean blocks or coffee particles finely separated in a compressing process, thus allowing people to enjoy unique deep and rich flavor of the roasted coffee bean, and vacuum packs a coffee bean tea-bag by a vacuum wrapper, thus maintaining the flavor of the roasted coffee bean for a lengthy period of time, and utilizing compressed coffee as an air freshener.

A combined container and stirring device which can be used with and resembles the shape of known infusion bags is disclosed. The combined container and stirring device comprises a body made of material that is resistant to liquids. The body comprises a lower body and an upper body. A filter bag surrounding a granular, powdered, or liquid product is provided. The filter bag is arranged within a cavity in the lower body. The upper body wraps around the lower body to form a compact shape when the device is in a folded state. The upper body extends upwardly from the lower body to form a handle when the device is in an expanded state.

A dip-type extraction bag having a bag main body in a planar shape, being formed of a water-permeable filter sheet and filled with an extraction material, wherein the extraction efficiency is improved by providing the body with a specific gripping portion formed from a thin plate-like material and regulating the characteristics of the sheet. The extraction bag includes a bag main body, a thin plate-like member provided on an outer surface thereof, and an extraction material sealed in the bag main body, which is subjected to extraction. The bag main body is a flat bag that has two facing surfaces. The thin plate-like member has a gripping portion that protrudes or is able to protrude from an upper side or the outer surface of the bag main body. The bending resistance (41.5? cantilever method in JIS L 1913:2010 (ISO method)) of the water-permeable filter sheet is 0.09 to 6.0 mN.Math.cm.

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 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.

A portion capsule includes a peripheral side wall, a first cover element and a second cover element, wherein the peripheral side wall, the first cover element and the second cover element form a closed interior. The first cover element and/or the second cover element include an arching directed into the interior. At least the cover element including the arching is manufactured of a biologically degradable material.

The present disclosure relates to a container system comprising a flat package, which has walls that define an interior space, and at least one fibrous water-soluble unit dose article in the interior space, where the fibrous water-soluble unit dose article comprises household care active agents.
