The invention relates to a system (S) for dispensing a product, comprising a pump (P) with a flexible pumping bellows, a lower-end flexible tubular wall section of which is automatically assembled on a chimney of a rigid end piece by interlocking of two complementary hooks, ensuring a sealed connection by pressing together of two complementary annular surfaces.

A dispenser includes a body having a an exterior surface, an interior surface, a first chamber, a first opening in fluid communication with the first chamber and extending through the body, a second opening in fluid communication with the first chamber and extending through the body, a first valve and a second valve disposed on the body, the valves having a closed and an open configuration, and an actuator disposed at least partially within the first chamber. The actuator may be configured to increase and decrease pressure in the first chamber such that the first valve and the second valve change from their respective closed configurations to their respective open configurations and from their respective open configurations to their respective closed configurations. When in the closed configuration, flow through the valves is impeded.

The invention relates to a jar comprising: a body having an upper wall, a flexible pouch containing a product to be dispensed, a deformable chamber delimited by a rigid wall and a flexible diaphragm and in fluidic communication with, for the one part, the flexible pouch and, for the other part, a dispensing orifice that opens out at the upper wall, a lid mounted on the upper wall so as to be movable between an open position and a closed position, the movement between these positions consisting of the lid being slid over the upper wall, pressurizing means designed to press on the flexible diaphragm while the lid moves from the closed position to the open position.

Some embodiments are directed to a valve made up of a rigid wall and a flap. The flap has a non-perforated flexible and deformable peripheral region situated facing the rigid wall. The rigid wall is perforated by at least one orifice situated facing the peripheral region. The flap is joined to the rigid wall by a non-deformable fixed connection. The peripheral region has a substantially conical shape before mounting with a large base and a small base and an inner face on the inner side of the cone. The peripheral region exhibits a deformation following the pressing of the inner face of the large base against the rigid wall in a assembled position.

A fluid dispenser comprising a deformable outer shell (1) and a flexible inner pouch (2) that is arranged inside the shell (1) in such a manner as to define between them a compression space (E) that is filled with air, the pouch (2) containing a fluid for dispensing through a dispenser valve (4), the compression space (E) communicating with the outside through an air inlet valve (5), such that deformation of the shell (1) puts the air contained in the compression space (E) under pressure, the air under pressure acting on the pouch (2), so that the fluid therein is then forced through the dispenser valve (4), the dispenser also comprising a head (3) that is fitted on the shell (1) and on the pouch (2), the head (3) comprising a first valve support (34) on which the dispenser valve (4) is mounted, and a second valve support (35) on which the air inlet valve (5) is mounted; the dispenser being characterized in that it further comprises a hood (6) that is fastened in non-leaktight manner on the deformable outer shell (1), the hood (6) holding the head (3) in place on the deformable outer shell (1) and on the flexible inner pouch (21), the hood (6) including a window (63) in which the dispenser valve (4) is positioned.

A squeeze sprayer for dispensing fluid product as a spray or spray mist includes a squeeze bottle and a squeeze sprayer closure attached to the squeeze bottle. The squeeze sprayer includes a cap which defines a chamber for receipt of air and fluid and further defines an outlet. Further included as a part of the squeeze sprayer is a valve which is assembled into the cap and a dip tube which is received by the cap. The dip tube is constructed and arranged to provide air to the chamber and the squeezing of the bottle forces air and fluid into the chamber and from there through the outlet to be dispensed as a spray or spray mist. A second embodiment provides an upright squeeze sprayer with a unique orifice cup. A third embodiment includes a directional adapter.

The disposable powder-dispensing bulb is configured for use with talcum powder. The disposable powder-dispensing bulb stores the talcum powder. The disposable powder-dispensing bulb dispenses the talcum powder. The disposable powder-dispensing bulb is disposable. The disposable powder-dispensing bulb is degradable after disposal. The disposable powder-dispensing bulb comprises a degradable bulb, a degradable cap, and talcum powder. The degradable bulb is a hollow containment structure. The talcum powder is stored in the degradable bulb. The degradable cap attaches to the degradable bulb. The degradable cap opens and closes to provide access to the talcum powder stored within the degradable bulb.

A dropper dispenser comprising: a fluid reservoir (1) including at least one movable wall (11) so as to put the fluid in the reservoir (1) under pressure; a cannula (24) having an outlet (25) that is designed to form a drop of fluid; and a valve (3) that is arranged between the reservoir (1) and the cannula (24) so as to control firstly the flow of fluid from the reservoir (1) into the cannula (24), and secondly the flow of fluid, and possibly air, from the cannula (24) into the reservoir (1), the valve (3), when subjected to sufficient pressure from the fluid in the reservoir (1), defining an opening (33) having a flow section that is proportional to the force exerted on the movable wall (11) of the reservoir (1); the dropper dispenser being characterized in that it further comprises a valve-opening limiter (27) so as to limit the opening (33) of the valve (3) while fluid is flowing from the reservoir (1) into the cannula (24), so as to create additional head loss that reduces the flow of fluid through the cannula (24).

Provided is a medication dispenser configured to discharge a liquid state medication stored therein by a pumping operation in a predetermined amount in a drop state and prevent a noise occurrence during medication discharge, and having a bacteria infiltration prevention function, wherein a flow path member and a second check valve are mounted in a liner, the second check valve is composed of a hemispherical cylinder mounted in an elevation space of the liner, having an open upper part, and of which a diameter decreases toward a lower end and includes a variable part in which the hemispherical cylinder is vertically variable and an opening and closing protrusion configured to perform supply and blocking of a flow path.

A dispensing head including: a cap having: an outer wall with at least one part referred to as the shell part and at least one part referred to as the pressing part that is made of a material more flexible than the at least one shell part; at least one outlet; an insertion orifice, a stopper, the stopper being mounted in the cap by being inserted into the cap from the insertion orifice side and in an insertion direction, at least one assembly, each assembly comprising: an inlet, passing through the stopper; a deformable pocket, an interior volume of which is intended to contain the fluid of this assembly and is delimited at least in part by the at least one pressing part of the cap; preferably a feed duct and/or a dispensing duct.
