A product dispenser is provided that includes a container within a shell, and a pump and insert for dispensing the product. A spring biases the container and pump away from the tip of the shell. The bottom of the container is pushed up relative to the shell to activate the pump, thereby dispensing the product.

A pumping-type cosmetic container having a side button, and, when pressing a button part which is positioned toward a side so as to be crossed at a right angle to a container body, a first check valve is closed while a second check valve is opened, and the contents flowing into a cylinder are discharged outward through an applicator. Therefore, with a simple structure of the pumping-type cosmetic container having a side button, a user can directly apply a fixed amount of contents to a desired region.

[Solution] A push-type dispenser 100 includes: a cap section 1 that is attachable to a container X containing a liquid; a housing section 2 fixedly fitted in a central portion of the cap section 1; a piston section 3 that is slidable in the housing section 2; a nozzle head section 4 fitted on an upper portion of the piston section 3; a spring section 5 housed in the housing section 2 and configured to bias the nozzle head section 4 upward; a tube section 6 attached to a lower portion of the housing section 2; an F valve A housed in the housing section 2 and configured to open and close a flow channel through which the liquid flows from inside the tube section 6 into the housing section 2; and an S valve B housed in the piston section 3 and configured to open and close a flow channel through which the liquid flows inside of the piston section 3, wherein the liquid is ejected from inside the housing section 2 by moving the nozzle head section 4 downward, the piston section 3 has a through-hole 34, provided in a side surface of the upper portion of the piston section 3, through which the liquid flows, and the through-hole 34 is opened and closed by rotating the nozzle head section 4 circumferentially with respect to the piston section 3.

When a cosmetic material is stored for several months, even in the case where hydrogen is contained in the cosmetic material at the beginning, hydrogen is gradually effervesced from the cosmetic material and after a certain time period has passed, the anti-oxidant effect cannot be maintained. Therefore, to solve this problem, a hydrogen-enriched cosmetic material container has hydrogen encapsulated in a bag formed of a hydrogen permeable sheet; then placing the hydrogen bag together with a liquid cosmetic material into a soft case formed of a flexible and hydrogen impermeable sheet, and then connecting a manually operable pump member for dispensing the liquid cosmetic material in the soft case through an opening of the soft case in an airtight manner.

Multifluid dispensing system comprising a receptacle of container in container type and an atomizer Within the receptacle, between at least two of the component-units is provided a connecting-system that includes at least some of: at least one residual interface; at least one permanent-joint of adhesive or weld type; at least one reinforcing functional-form. The connecting-system preferably extends on the entire height of the receptacle. The parts of the connecting-system are preferably, at least partially, superimposed and contained within an operational-section. Additionally, within the receptacle is provided a partitioning-system that consists of at least one mobile-sector which develops via delamination from an internal component-unit. Within the receptacle is equally provided a compression-system that consists of at least one mobile-sector which also develops via delamination from an internal component-unit. The atomizer is made entirely of plastic, is of multifluid type, comprises a return-spring having two curved arms, and a precompression valve-system.

A pump dispenser includes an actuator having at least one outward projection and a rotatable actuating collar at least partially surrounding the actuator and having at least one ramp rib defining a lower surface which engages the at least one outward projection such that rotation of the rotatable actuating collar acts on the actuator to dispense a product from or through the pump dispenser.

Disclosed is a liquid pump (100, 200, 300, 400, 500, 600, 700, 800, 900), including a movable unit and a fixed unit. The movable unit is capable of moving relative to the fixed unit so as to pump a product out. An elastic mechanism (130, 230, 330, 430, 530, 630, 730, 820, 930) is provided between the movable unit and the fixed unit, and the elastic mechanism (130, 230, 330, 430, 530, 630, 730, 820, 930) comprises at least one elastic strip (131, 231, 331, 431, 531, 631, 731, 821, 931). The elastic strip (131, 231, 331, 431, 531, 631, 731, 821, 931) applies a biasing force to the movable unit to restore the movable unit after the product is pumped. The liquid pump (100, 200, 300, 400, 500, 600, 700, 800, 900) further comprises an elastic mechanism adjusting member movable between a first position in which the elastic strip (131, 231, 331, 431, 531, 631, 731, 821, 931) of the elastic mechanism (130, 230, 330, 430, 530, 630, 730, 820, 930) is in a relaxed state, and a second position in which the elastic strip (131, 231, 331, 431, 531, 631, 731, 821, 931) of the elastic mechanism (130, 230, 330, 430, 530, 630, 730, 820, 930) is in a preloaded state. With the provision of the elastic mechanism adjusting member, it is convenient to press down a pressing head (110, 210, 310, 410, 510, 610, 710, 910) during use, and the yielding deformation of the elastic strip (131, 231, 331, 431, 531, 631, 731, 821, 931) due to long-term stress can also be avoided.
