    Abstract: A pump dispenser has a pump body and a reciprocable plunger with a lock-down mechanism, comprising internal or external lock formations of the plunger and body, such as thread formations, by which the plunger can be locked down for shipping and released subsequently by a rotational release movement. To supplement security for demanding shipping conditions the dispenser also has a supplementary catch mechanism in which respective catch formations of the plunger and body engage selectively in the locked-down position to inhibit the rotational release movement. The catch formations may have circumferentially-directed surfaces which engage between the underside of a plunger head having a shroud and a nozzle and the top of the body beneath the plunger head. They can be released by resilient deformation of one or more of the catch formations.

    Abstract: A pumping device (100), comprising a movable part and a fixed part. The movable part is capable of reciprocating relative to the fixed part, thereby dispensing, by means of a straw (30) connected to the fixed part, a product contained in a container (20). The pumping device (100) comprises elastic members (150, 250, 350, 550, 650, 850, 950, 1050), one end of each of the elastic members (150, 250, 350, 550, 650, 850, 950, 1050) is connected or supported on the movable part, and the other end of each of the elastic members (150, 250, 350, 550, 650, 850, 950, 1050) is connected or supported on the container (20), or is supported on the container (20) by means of the fixed part. The pumping device (100) having the described structure allows the elastic members (150, 250, 350, 550, 650, 850, 950, 1050) to be fabricated using plastic, and is also capable of obtaining the required elasticity.

    Abstract: Disclosed is a full-plastic liquid pump and a containing container having same, which employs a plastic spring (12) and a plastic one-way valve (15), wherein the plastic spring (12), the plastic one-way valve (15), and other parts of the full-plastic liquid pump are all made of plastic materials. The full-plastic liquid pump can be recycled as a whole without splitting, which reduces the cost of recycling the full-plastic liquid pump, and facilitates improving the utilization rate of resources, thereby better facilitating protecting environment.

    Abstract: A food pump is provided with a safe outlet valve and an outer mounted spring. A pressing head, a primary column, a secondary column, a piston, a pump chamber, a spring and a bottle locking cover are also provided. A lock cover for fixing the primary column to the pump chamber is fixed on the pump chamber. An outer side of an upper end of the lock cover is provided with a cover flanging which is turned outwards and then turned downwards to stretch. An inner side of a locking flanging is provided with an inner thread in threaded fit with an outer thread of a lock opening of a lock cover, such that the primary column, the secondary column, the piston, the pump chamber, the spring, a glass bead and the lock cover can be stored and transported independently, thereby matching different pressing heads and bottle locking covers.

    Abstract: A dispenser pump has a plunger operable in a body including an outer cylinder body having a vent opening in its sidewall and a body insert fitting into the top of the body cylinder and providing an external collar through which the plunger stem operates. The body insert has a lock-down thread to lock down the plunger for shipping. The insert also has an undulating annular vent-control bead extending right round its cylindrical outer surface, engaging the cylinder wall with interference for either blocking or unblocking the vent opening, according to whether the vent-control bead lies above or below the interior vent opening, by rotation between the body cylinder and body insert. The rotation can be driven by rotation of the plunger head, which makes a catch engagement with the top of the body insert. Blocking the vent during shipping reduces leakage.

    Abstract: Disclosed are a pressure regulator for reciprocating pumps comprising an audible low pressure blow off and pumps comprising the pressure regulator. Also described is a pump comprising a larger diameter barrel with a higher volume for inflating an inflatable object at a lower pressure and a smaller diameter barrel with a lower volume for inflating an inflatable object at a higher pressure, wherein the pump is switchable to operate using either the larger diameter barrel or the smaller diameter barrel using a single lever attached to an end cap of the smaller diameter barrel.
