A fluid container is disclosed with a cap body made of rigid or semi rigid material and a valve body disposed within the cap body and movable between and open and closed position. The valve body is made of a semi flexible semi rigid material that has a coefficient of thermal linear expansion that is smaller than that of the cap body. The cap body and nozzle valve are configured with three different hermetic seals to counteract the effects of exposure to heat and cold over time and thereby extend the useful life of the cap and valve.

A spouted pouch (1) has a spout (10) with a neck (14) extending upward from an attachment portion (12). A cap unit (30) has a cap body (35) and an integrated ring member (50), made as one piece of plastic. A ring member is integrally formed to the lower edge of the skirt of the cap body and comprises an annular base portion (51) connected via breakable bridges (53) to the skirt. The base portion and the spout body (11) have cooperating permanent snap-fit joint portions (56, 21, 23) that keep the ring member fixed to the spout upon removal of the cap body. The pouch further comprises a flow control device (80) made distinct from the spout and from the cap unit. The flow control device is mounted to the neck (14) and has an external part (82) located outside of the exterior surface of the neck. The cap body is arranged over the neck and the flow control device. The ring member and the external part of the flow control device have cooperating retention portions (55, 83).

A device for the transport, storage, opening and closing of a cartridge capable of receiving a liquid, the cartridge being closed by a valve, includes a shell, a base, and a cap including a tubular body, a neck, a stopper, a safety system and a locking ring. The cartridge is intended to be mounted in such a device. A method for mounting such a cartridge in such a device is also included.

A fluid container is disclosed with a cap body made of rigid or semi rigid material and a valve body disposed within the cap body and movable between and open and closed position. The valve body is made of a semi flexible semi rigid material that has a coefficient of thermal linear expansion that is smaller than that of the cap body. The cap body and nozzle valve are configured with three different hermetic seals to counteract the effects of exposure to heat and cold over time and thereby extend the useful life of the cap and valve.

The utility model belongs to cups, particularly a new side push button lid. The cup lid comprises a threaded body, a hold-down piece, a sealing seat, an upper lid body, an upper lid plate, a push rod, a sealing valve, and a button connected successively from bottom up. The middle area of the lower end of the push rod is movably connected with the holder on the hold-down piece; one end of the push rod is connected with a sealing valve in a snap-fit manner; the other end is connected with a drive rod of the button; and the upper end of the seal valve abuts the water outlet of the upper lid plate. The pressed button drives the drive rod to apply a pushing force to the push rod to force the sealing valve to move downward, the sealing valve is removed from the water outlet and water is supplied.

A mechanism for measuring an amount of a liquid composition and discharging it, and a quantitative dispensing container and a quantitative applicator including such a mechanism including a base and a head defining a measurement space therebetween. The base and the head are configured to be capable of changing the volume of the measurement space in response to a predetermined operation of the head including a measurement operation for increasing the volume of the measurement space and a discharge operation for reducing the volume of the measurement space. The base includes a first passageway for allowing the composition to flow from the outside into the measurement space, and a first check valve located on the first passageway. The first check valve of the base increases its sealability if there is a positive pressure in the measurement space.

Double container includes: inner layer body provided with upper opening; outer layer body accommodating inner layer body and including mouth portion provided with aperture; and dispensing cap provided with content dispensing spout and fitted to mouth portion. Double container further includes: inside plug provided with dispensing passage and fitted to upper opening; and check valve configured to open and close dispensing passage. Dispensing cap has a cylindrical wall, and cylindrical wall has a lower end portion fitted to an outer circumferential surface of outer layer body to provide vent region inside dispensing cap. Throttle passage is provided in a passage extending from ambient air introducing hole through vent region to aperture.

A valve structure, a bottle cap, and a bottle are provided, relating to the technical field of bottles. The valve structure includes a rigid connecting portion, a flexible valve body, and a connecting part. The rigid connecting portion has a liquid flow channel, and the liquid flow channel axially penetrates through the rigid connecting portion. The flexible valve body is located inside the liquid flow channel and connected to the rigid connecting portion, a valve opening is arranged at a middle of the flexible valve body, and the flexible valve body is configured to be deformed under pressure to open the valve opening. The connecting part is arranged on an outer wall of the rigid connecting portion, and the rigid connecting portion is detachably connected to an inner wall of a water outlet of a cap body by the connecting part.

A sealing unit comprising a male and a female sealing unit portion (300, 200) are provided for selectively sealing and opening a liquid container (100). The female sealing unit portion comprises a tubular element (210, 410) comprising a liquid passage (211) configured to be fixedly positioned relative to the container and a valve (220) with a tubular valve portion (229) axially movable between a closed and open position. The valve may comprise a flexible valve skirt portion (219) configured to bend when the tubular valve portion is moved to the open position by an external axial force and to urge the tubular valve portion back from the open position to the closed portion when the external axial force is removed. The male sealing unit comprises a rigid operating tube (310) configured to be axially movable inside the liquid passage so as to engage the force receiving part of the valve portion and apply the external axial force to open the valve portion.
