The present disclosure relates to a spring for a pumping-type container having a first helical part and a second helical part, and a pumping-type container including the same, and has been made to solve a problem caused by independent elastic deformation of the first helical part and the second helical part.

The present disclosure relates to a pumping-type container, and is to solve the problem of a discharge opening/closing part in which the force of pressing a button toward a cylinder is great and the assembly operation thereof is difficult. To this end, a discharge opening/closing part may be configured to have an elastic deformation opening/closing part which is made of an elastic material and has an opening/closing cutting line thereon, and is detachably coupled to the button such that the elastic deformation opening/closing part closes the end of the button discharge channel part.

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 pasty products which has a head, a pump, an actuator, and a container tube is provided. The pump is provided with a plurality of flexible flaps protruding inwardly from a dome-shaped elastically deformable cap of the pump or from a connection portion of the pump to form a lower or suction valve.

A dispenser for dispensing flowable, for example liquid or pasty, compounds, includes a storage tank for the compound and a pump chamber, and also includes a dispenser head, wherein the dispenser head has a dispensing mouth and the dispenser head can be pressed down against a stop in the direction of a vertical axis of the dispenser to perform a pumping operation, wherein the stop is adjustable in terms of its height. In order to give a dispenser of the kind in question an advantageous design, in particular with regard to handling, the stop is formed by an outwardly exposed sliding track that can be rotated around the vertical axis, against which a projection that protrudes radially outward on the dispenser head comes to a stop when pressing down.

The device for packaging and dispensing a product includes a preassembled inner unit mounted in a hollow body, with a dispensing head surrounded by an upper connector which allows removably attaching the body. The inner unit includes a reservoir, and the head sealingly closes the opening of the reservoir. A peripheral retaining ring for the inner unit keeps the reservoir and head integrally secured. The connector is connected to the body by a locking action which is achieved by relative pivoting between the connector and the body, without interference with the ring. An actuating portion of a dose metering pump of the head is accessible on the top via a channel of the connector, while a tubular outer portion of the connector covers the area of attachment to the body, by axially extending an outer wall of the body.

A multiple dose syringe has a first valve defining a first valve opening pressure and a second valve defining a second valve opening pressure. A storage chamber in fluid communication with the second valve stores multiple doses of a substance therein and includes an outlet for dispensing multiple doses of the stored substance therethrough. A compression surface is movable between first and second positions and defines a compression chamber between the compression surface and the first valve. Movement of the compression surface in a direction from the first position toward the second position dispenses substance in the compression chamber through the first valve and out of the syringe. Movement of the compression surface in a direction from the second position toward the first position causes substance to flow from the storage chamber through the second valve and into the compression chamber.

A piston for a reservoir of a dispenser of a fluid product without air intake, and presenting a central axis X includes both sealing means and also guiding means. The sealing means extend in a plane orthogonal to the axis X and define a single external sealing line in a closed loop, distal from the axis X, capable of coming into contact with an inner wall of the reservoir 10. The guiding means include a base from which extends one or more tabs with free ends defining external guide points, distal from the axis X, capable of coming into contact with the inner wall of the reservoir.

A fluid dispenser assembly having a fluid reservoir (4), a dispenser member (5), and a dispenser orifice (62). The fluid reservoir (4) includes a piston (42) movable in leaktight sliding contact in a slide cylinder (41) over a maximum stroke defined between a start position that corresponds to a substantially full state of the reservoir, and an end position that corresponds to a substantially empty state of the reservoir. The dispenser assembly further includes an RFID tag (40) that is secured to the piston (42).

A container includes an airless dispenser for a cosmetic product. The container includes a hollow vessel body defining a sealed receptacle for containing a cosmetic product and a base. A dispensing head mounts at one end of the container and communicates with the receptacle for dispensing the cosmetic product. An actuator is associated with the dispensing head and configured to be operable to cause a pressure drop inside the receptacle. An outlet nozzle allows dispensing a desired quantity of cosmetic product when the actuator is operated. A plunger slidably and sealably mounts in the receptacle and is pushed from a spaced-out position towards a closer position relative to the outlet nozzle due to the pressure drop generated by operating the actuator. The hollow vessel body is made of glass, is substantially cylindrical, and defines a substantially constant cross-section through the axial segment in which the plunger is slidable.
