A receptacle for mixing different kinds of materials includes an outer receptacle for holding cosmetic contents; a shoulder member of a cylindrical member with the upper and lower portions opened, which is screw-coupled to an upper opening portion of the outer receptacle; a pump coupling member of a disk-shaped member coupled to the inner circumference of the shoulder member, which couples a first pump set and a second pump set side by side; an inner receptacle of a cylindrical member, an upper flange of which is placed between a lower surface of the pump coupling member and an upper surface of the upper opening portion of the outer receptacle, which is partitioned into a first and a second space portions, into which a first and a second pump sets are inserted from the upper part, respectively.

The device for packaging and dispensing a product comprises a container provided with at least one variable volume compartment, and a dispensing head fastened to the container. The dispensing head comprises a mounting base, an internal piston that is movable in translation along a displacement axis Y-Y and delimits, inside said base, first and second pumping chambers, and at least one actuating rod that extends through the pumping chambers and the piston and projects from either side of the mounting base. The actuating rod internally delimits a first feed duct in communication with a first outlet orifice of the dispensing head and a second feed duct separate from said first duct and in communication with a second outlet orifice of said head.

A refillable fluid dispenser having a dispenser head including a fluid pump, such as a pump or a valve; a reservoir of variable volume; and a filling valve that is connected to the reservoir. The dispenser further comprises an air pump of variable volume, having a volume that varies inversely with the volume of the reservoir, so as to create resistance to the variation in volume of the reservoir.

An all plastic compression spring assembly includes a slotted tubular spring element formed from a tensile polymer material and upper and lower loading cones received at opposing upper and lower ends of the slotted tubular spring element. The upper loading cone may be axially compressible towards the lower loading cone within the slotted tubular spring element whereby the slotted tubular spring element radially expands in tension to create an opposing radial contraction force, and in turn, an axial extension spring force. When released, the spring element elastically returns to its normal at rest shape, returning the cones to their normal at rest positions. In some dispenser configurations, the lower loading cone may be stationary or fixed within the dispensing head and the upper loading cone may be downwardly compressible toward the lower loading cone by movement of a nozzle head.

Disclosed is a lotion pump comprising: a pressing head (10) comprising a pressing head body (11); a cylinder (30); a cylinder head connected to an upper end of the cylinder and having an inner hole; a threaded sleeve (20) connected to the cylinder head; and a piston rod (40), with one end being connected to the pressing head body, and the other end extending into the cylinder and being provided with a piston (50). The lotion pump further comprises a neck sleeve (13) formed on the pressing head body. A first slope is formed on a lower portion of the neck sleeve, and a second slope matching the first slope is formed on the top of the threaded sleeve. The lotion pump having the foregoing structure can ensure the sealing against the outside when the lotion pump is in a standby state or an upper locked state, so as to prevent water from seeping into the lotion pump during bathing.

The present invention disclosed herein relates to a bead discharge pump container, in particular, a bead discharge pump container, which has a cylinder-type pump structure having a check valve and designed by changing a check valve structure, a piton rod structure, a gap between a piston rod and a seal cap, and the like such that the bead contents are easily discharged without being burst.

There is provided a cosmetic vessel. The cosmetic vessel includes an airless pump configured to discharge cosmetics accommodated therein by using a piston that rises in a cylinder, a discharge plate provided at one side of the airless pump and having at least one discharge hole, and a guide unit provided between the airless pump and the discharge plate. A lower end of the guide unit is combined with the piston and rises or falls in a state of being integrated with the piston.

A fluid dispenser head (T) including a spray wall (26) that is perforated with a network of holes (O) through which the fluid under pressure passes so as to be sprayed in small droplets;

the dispenser head being characterized in that the network of holes (O) comprises at least two series of holes (O), with the holes (O) of a given series presenting holes that are substantially identical in size, and with the holes (O) of different series presenting holes that are different in size, such that one series of holes (O) generates a spray of small droplets with droplet sizes that define a first Gaussian distribution, while another series of holes (O) generates a spray of small droplets with droplet sizes that define a second Gaussian distribution that is offset relative to the first Gaussian distribution, thus producing a complex spray having at least two distinct Gaussian distributions.

Provided is an elastic member according to an embodiment of the present invention. In the elastic member, a protrusion portion formed outward and a recessed portion formed inward may be repeatedly formed in a longitudinal direction, an outer groove may be formed in the protrusion portion along an outer circumference of the elastic member, an inner groove may be formed in the recessed portion along an inner circumference of the elastic member and guide bending-deformation of the protrusion portion and the recessed portion during elastic compression.

A manually operated pump including: an inlet one-way valve; a pump chamber downstream of and in fluid communication with the inlet one-way valve; a piston interior to the pump chamber and slideably engaged with the pump chamber; an actuator engaged with the piston or the pump chamber; a block thermoplastic elastomeric spring engaged with the actuator to move the actuator as the block thermoplastic elastomeric spring relaxes; and an optional outlet one-way valve downstream of and in fluid communication with the pump chamber.
