A dispenser for discharging liquid to pasty masses, has a pump head and a pump chamber, having a pump chamber wall and an inlet valve and an outlet valve. The pump chamber is formed by a bellows part, on which the inlet valve is integrally formed. The inlet valve is retained of retaining arms, which extend in the peripheral direction of the inlet valve and are connected to the pump chamber wall and to the inlet valve, and the inlet valve forms a peripherally extending valve lip, which freely protrudes in cross-section. The inlet valve extends in the shape of a circle segment in a longitudinal cross-section of the bellows part, having an upper dome segment and the lower valve lip. The connection to the retaining arms is formed at a height center of the inlet valve or at an offset therefrom toward a free edge of the valve lip.

A device for dispensing fluid from a fluid container, the device capable of being set to different discrete and repeatable/equal dispensing amounts, depending on the amount of fluid required to be dispensed by the user for various applications and uses. The device may also be set to an off or closed position to prevent accidental dispensing of fluid when not in use. The device is preferably configured to be affixed to the outer surface of a fluid container, which fluid container is preferably a flexible bag or pouch.

In accordance with one embodiment of the present invention, the invention has two containers arranged head to head so that the opening at each head is attached to a central core that acts as cup, measuring device or simple connector or all of the aforementioned. A multiple container sandwich bag such that successive multiple containers are arranged end to end or the containers are arranged back to back.

In one aspect, a dispenser is provided herein for dispensing flowable material, such as sunscreen lotion, including a resiliently deformable body encompassing a closed volume with an optional flexible pouch disposed therein to accommodate the flowable material. A discharge element is also provided having at least one discharge opening, along with at least one valve regulating flow from the closed volume or the flexible pouch and through the discharge opening. The body is configured so that a threshold amount of deformation of the body causes the flowable material to urge from the closed body through the discharge opening or the pressure increase of the closed volume acting on the flexible pouch sufficiently so that flowable material accommodated in the flexible pouch is urged therefrom through the discharge opening. Advantageously, the dispenser of the subject invention allows for a generally isobaric environment to be created which acts evenly about the flexible pouch. This allows for a more even application of pressure acting against, and a more complete depletion, of the optional flexible pouch.

A container for pasty or semi-liquid products of substantially tubular shape and extending along a longitudinal axis. The container includes: a first longitudinal end which is closed and flattened; an opposite second longitudinal end including an opening and a dispensing element; a first side wall and a second side wall, opposite each other and interposed between the first longitudinal end and the second longitudinal end. The container includes, at the first side wall and second side wall, a plurality of first lines of weakness which are transverse to the longitudinal axis and which define a plurality of corresponding zones; the first lines of weakness are such that the zones of the first side wall and of the second side wall are selectively squeezable, in twos, towards each other and progressively from the first longitudinal end to the second longitudinal end, defining corresponding stable configurations for the zones.

The tube (1) includes a connector (9) with a dispensing duct (13) which connects a dispensing opening (11) to a reservoir (3). For the dosed dispensing of a liquid from the reservoir (3) through the dispensing opening (11), a throttle insert (31) is inserted into a distal section (9b) of the connector (9) and is connected in form-fitting fashion to the connector (9). The connection of the throttle insert (31) to the connector (9) is preferably realized by a radial pressing action. The throttle insert (31) is preferably of dome-like form and delimits at least one primary throttle duct (47) which forms in the dispensing duct a constriction which limits the volume flow of the liquid from the reservoir (3) to the dispensing opening (11).
