A beta container for an alpha-beta port system includes a sheath for receiving transport material and a flange part having a through opening for transferring the transport material from and/or into the sheath, a first interface for a reversible connection to an alpha connection of the port system, and a second interface for releasable attachment of a beta cover for closing the through opening. An edge of the sheath is connected with a first surface of a ring which encompasses a jacket surface of the flange part, the first surface and the jacket surface having different materials. An elastic bellows may be fastened to the flange part such that, in the relaxed state, it engages over the second interface and/or projects out of the through-opening on the side facing away from the sheath, and such that it can be compressed. At least one transponder for transmitting an identification may be arranged on the flange part.

An open container closure assembly and method for attaching to an upper end of an open bag style container includes a sleeve including a front wall, a back wall, and a pair of lateral edges joining the front and back walls. The front and back walls abut each other. The sleeve has a top edge and a bottom edge, and each are open. A fastener is mounted on the sleeve adjacent to the bottom edge and engages an exterior surface of a bag style container such that an open upper end of the bag style container is positioned within the sleeve. A seal is attached to the sleeve adjacent to the top edge and closes the top edge in an air-tight condition.

A leakproof cap of a soft water bottle and a water bottle are disclosed. The leakproof cap includes a cap body having an installation cavity with a screw thread circumferentially arranged on a side of the installation cavity, and a sealing member annularly arranged on another side of the installation cavity that is opposite to the screw thread at a predetermined distance. The sealing member is an elastic sealing member and a side of the sealing member facing the screw thread has a plurality of sealing rings. The sealing rings are arranged concentrically and evenly, and a sealing cavity is formed between adjacent sealing rings. When the bottle opening deforms following the bottle body, the sealing member adapts to the deformation and blocks the liquid through the plurality of sealing rings.

A pouring spout sealing structure of an inside plug includes a sealing member including a bottom part for sealing an opening of a pouring spout of the inside plug, a peripheral wall rising from the peripheral edge of the bottom part, and a knob part extending from the peripheral wall, in which the sealing member is connected to the upper end of the opening of the pouring spout at the peripheral edge of the bottom part, the connected portion constitutes a thin part breakable by a certain pulling force, and the peripheral wall is inclined upwardly and outwardly from the opening of the pouring spout. The container pouring spout sealing structure achieves both sealability and easy opening properties, reduces number of parts and manufacturing steps, and is applicable to small containers such as cosmetic containers.

The present invention discloses a portable coffee brewing apparatus and a using method therefor, and belongs to the technical field of coffee brewing. The apparatus comprises an upper lid, a bottle body, a bottom lid, a pushing structure, and a powder cartridge, wherein two ends of the powder cartridge are provided with a first filtering device and a second filtering device with a permeability lower than that of the first filtering device, the pushing structure is configured to push the powder cartridge to move axially along the bottle body, and the upper lid and the bottom lid are in sealing connection with two ends of the bottle body in a detachable manner. The coffee brewing apparatus of the present invention adopts the second filtering device with a low permeability to filter, which is beneficial to pressurization and infiltration to improve the concentration of the coffee.

A resealable airtight storage jar assembly that includes a portable jar body defining ajar opening, an inner cap member with an internal sidewall extending from an upper wall and an inner cap sidewall extending from the upper wall and defining a threaded configuration corresponding to a threaded configuration defined on a sidewall of the portable jar body, wherein the inner cap member is operably configured to have a hermetically sealed position covering the jar opening. The jar assembly also includes an outer cap member with a lip radially extending from a sidewall thereon and to restrict longitudinal movement of the inner cap member thereover. The jar assembly also includes an elastomeric gasket coupled to the inner cap member and operably configured to seat over and seal the jar body defining the jar opening.

A container lid assembly includes a cover, a pivoting lid connected with the cover, and a lid gasket connected with the pivoting lid. The cover is configured to fit with an associated container and defines an opening through the cover. The pivoting lid is positioned in the opening in the cover. The pivoting lid is movable between an open position and a closed position.

A sealing cover for covering an opening of a barrel body includes an outer cover body, an inner cover body, an airtight ring and an operating member. The outer cover body includes two pivot connecting portions. The airtight ring is sleeved on an outer peripheral surface of the inner cover body. The operating member is pivotally connected to the pivot connecting portions and the inner cover body. The operating member is operable to pivot so as to drive movement of the inner cover body between a sealed position and an unsealed position. When at the sealed position, the airtight ring is deformed and airtightly pressed between the barrel body and the outer cover body. When at the unsealed position, the airtight ring restores to its original shape and is configured not to be pressed between the barrel body and the outer cover body.

A cap for a squeeze bottle that is simply constructed, easily manufactured, simple to assemble and easily reassembled. The cap includes three components, a rounded lid with a slot, a nozzle with a near spherical base and an extended cone portion, and a gasket with a top, bottom and side walls to form a pocket. The user may insert and remove the nozzle from the pocket by pushing and pulling, respectively, on the stem.

A reusable container housing. The housing includes a hollow shell that receives a recyclable cup, e.g., filled with powdered detergent, and holds it sealed and secure. A lid of the housing, when placed on top of the shell to seal its top opening, causes the cup within to be pressed downward past a set of detents and locked thereby. The hollow shell includes an open bottom sealed with a flexible diaphragm. To eject the cup from the housing (e.g., when it is empty), the lid is removed, and the flexible diaphragm is pushed upward thereby forcing the cup upward and past the detents. The cup may then be removed and replaced.
