The invention relates to a set of dispensing containers (100) for liquid and semi-liquid substances, comprising a main dispening container (1) and a secondary dispensing container (4). The main dispensing container (1) comprises an outlet (2) and a main pump (3) and is suitable for placing more substance therein and for filling of the secondary dispensing container (4), and the secondary dispensing container (4) is suitable for containing a smaller amount of substance and comprises a pumping mechanism, wherein during filling the secondary dispensing container (4) is connected to the main dispensing container (1). A sliding mechanism (7) is located at the outlet (2) of the main dispensing container (1), and the main pump (3) is mounted in the outlet (2) of the main dispensing container (1), said main pump (3) being connected to the atomizer (8) at the outside of the main dispensing container (1). The atomizer (8) is equipped with a control valve (9) for opening and closing of a nozzle (11) of the atomizer (8), and in an upper part of the atomizer (8) an upper valve (10) is located for connecting the channel of the main pump (3) with the secondary dispensing container (4), when the secondary dispensing container (4) is mounted on the atomizer (8). The secondary dispensing container (4) and the outlet (2) of the main dispensing container (1) contain means for a detachable attachment of the secondary dispensing container (4) to the main dispensing container (1).

A lotion pump includes a movable portion and a stationary portion. A shifting mechanism is formed on the movable portion and the stationary portion, which shifts the elastic restoring mechanism of the lotion pump between a standby state and a non-standby state as the movable portion rotates or moves up and down. The structure of the lotion pump can prevent the spring from yielding due to compressed for a long time, while can also realize a form of locking at lower position.

A dispenser is disclosed that includes a pump having a pump chamber that receives a fluid, a pulsation dampener, and a discharge conduit. The pulsation dampener has a dampener housing with an interior volume and a dampener housing opening. A spring biased movable piston is located in the interior volume of the pulsation dampener and defines a variable volume headspace between the piston and the dampener housing opening. The discharge conduit provides fluid communication between each of an outlet of the pump chamber, the dampener housing opening, and a nozzle such that, when the pump is activated, at least a portion of fluid from the outlet of the pump chamber flows within the discharge conduit to the dampener housing opening. The dispenser is configured to, when the pump is activated, emit a substantially constant stream of fluid from the nozzle for at least one second.

A dispenser for discharging flowable compounds has a reservoir for holding the compound and a dispensing pump. The dispenser has a longitudinal axis. The dispensing pump has an inflow and an outflow channel, a pumping chamber which is delimited on the inflow and outflow sides by valves, and a head piece. The head piece has a dispensing opening. A pumping part can be moved relative to a cup part against an elastic force of a restoring device in order to achieve a pumping stroke, and the head piece is coupled to the pumping part with respect to motion such that a motion of the head piece from a completely depressed position to a reachable extension height corresponds to the pumping stroke. A variable limiting device is provided for variably limiting the pumping stroke and a change in the pumping stroke corresponds to a change in the extension height.

A spray pump comprising a small piston and an upper pump rod with a liquid accumulation cavity is provided. The upper pump rod is provided with a liquid discharge hole communicates with the liquid accumulation cavity, and the small piston is provided with a sealing column for sealing the liquid discharge hole. A central column is provided with an ejector rod extending into the liquid discharge hole, and a liquid flow gap is disposed between the ejector rod and the liquid discharge hole. A central hole communicates with the liquid discharge hole is disposed at a central part of the central column, and a press head with a lower part being fixed with the central column. A press plate is fixed with the upper pump rod, and a press gap is disposed between an upper side of the press plate and a lower side of the press head.

Provided is an elastic member according to an embodiment. The elastic member includes an upper support, a lower support provided under the upper support, and at least one elastic part configured to connect the upper support to the lower support, wherein the elastic part includes an upper support portion formed downward from the upper support, a lower support portion configured to extend upwardly from the lower support, and a connecting portion configured to connect the upper support portion to the lower support portion with a predetermined inclination and to be bent and deformed when the elastic member is pressed.

A biasing member for use in reciprocating dispenser pumps is contemplated. The member is made completely of polymeric materials and is suitable as a direct replacement for metallic coil springs. The biasing member includes spiral shape defined by inner and outer helix traces, with a series of perforations provided along one or both of those traces. These perforations, in conjunction with thinned channels, the size and shape of holes, and the size and shape of apertures, all cooperate to allow for a spring with sufficient resilience and greater spring force in comparison conventional, all-polymer biasing members.

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.

A pump container includes: a container in which a liquid is contained; a shoulder member configured as a cylindrical member, the upper and lower portions of which are open, the shoulder member having a lower outer peripheral portion formed to have an inner diameter larger than that of an upper inner peripheral portion; a valve housing comprising a cylinder portion, a hose being inserted/connected into/to the lower portion of the cylinder portion, the upper portion of the cylinder portion being open, the valve housing comprising an outer-periphery cylinder portion configured on the outer peripheral edge of the cylinder portion in a flared shape, the upper portion of the outer-periphery cylinder portion being open, the valve housing comprising an upper-end insertion portion bent outwards, and the valve housing comprising a seating portion bent outwards from the upper end of the upper-end insertion portion and a discharge cap.

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.
