A pump dispenser where the pump assemblies does not require disassembly to be recycled in current recycling streams. The pump assembly can include a plastic spring that does not lose stiffness over time and does not interact with the liquid product.

A wearable accessory for storing and dispensing liquid and a method of using the same are provided. The accessory can include a housing having a loop structure with a through-hole configured to receive a hand of a user therethrough, and a liquid container enclosed within the housing. The through-hole can be sized for the user's lower arm. The liquid container can include a first end having a sealable opening for adding liquid for storing and dispensing, and a second end in fluid communication with a nozzle opening recessed in an external surface on the front side of the housing. The nozzle opening can be configured to receive and dispense a volume of atomized liquid from a sprayer coupled to the second end of the liquid container when the sprayer is activated by an actuator integrated into the housing. The recessed nozzle opening prevents the user from contacting the sprayer.

The present disclosure relates to a cosmetic container wherein a holder side portion has holder engaging protrusions formed on the inner surface thereof so as to face each other, left deformation assistance long holes are formed in straight shapes in left areas of the holder engaging protrusions, respectively, so as to extend from the lower end to positions higher than the holder engaging protrusions, and right deformation assistance long holes are formed in straight shapes in right areas of the holder engaging protrusions in parallel to the left deformation assistance long holes, respectively, so as to extend from the lower end to positions higher than the holder engaging protrusions. Accordingly, the inner container can be replaced easily.

A dispenser for dispensing a liquid product, the dispenser comprising a housing, a pump assembly, a dispensing head, and an inner container. The inner container accommodates the liquid product and is configured to be inserted into a cavity of the housing. The inner container is replaceable and detachably connected to the housing such that the housing, the pump assembly, and the dispensing head can be retained for reuse while the inner container can be replaced with a new inner container. A protrusion is provided on an underside of the inner container that a user can grip to rotate the inner container in a clockwise or anticlockwise direction to disengage the inner container from the housing.

An example portable fluid spraying system includes a handheld fluid sprayer. The handheld fluid sprayer includes a fluid reservoir configured to store a fluid, a pump configured to pump the fluid from the fluid reservoir to an outlet of the handheld fluid sprayer and a handle. The handheld fluid sprayer includes a first trigger proximate the handle, configured to control fluid flow to the outlet. The portable fluid spraying system includes a fluid hose having a coupling mechanism configured to removably couple to the handheld fluid sprayer proximate the outlet and a fluid spray gun. The fluid spray gun includes a gun inlet configured to couple to the fluid hose and receive the fluid from the handheld fluid sprayer, a gun outlet configured to expel the fluid in a spray pattern and a second trigger configured to control fluid flow to the gun outlet.

Automatic electric actuation of the pump of a liquid dispenser apparatus is provided by a stepper motor having a threaded hollow liquid-conducting tube positioned therein and configured such that motor drives the hollow tube up and down in response to supply of a plurality of electrical pulses thereto. A lower end of the hollow tube is constructed to inter-fit with a stem of the pump such that driving the hollow tube up and down creates a pumping action.

A dispensing pump (10) for liquids, viscous materials, foams, gels, etc. includes a resilient cup spring (18) so that the entire pump can be more easily recycled. The dispensing pump (10) includes a base portion (12), an inlet valve (14), a piston valve (16), a cup spring (18), a spring guide structure (20) and a pump actuator (22). When actuated, the cup spring (18) is elastically deformed over opposing spring ribs (39), and then upon release, the cup (18) elastically returns to its normal at rest shape, returning the guide (20) and pump actuator (22) to their normal at rest positions. The cup spring (18) includes structures which interact with the piston valve (16) to open the outlet valve.

Disclosed is a heterogeneous contents mixing container with improved productivity and sealing ability. The heterogeneous contents mixing container includes a container body for containing a second content; a first content receiving member formed in the container body to contain a first content and including an upper separation cap and a lower fixing cap; a shoulder rotatably coupled to the container body; a lift guide member fixed to the container body and formed with a spiral groove; a lift member moving up by a rotation of the shoulder and formed with a lift protrusion; a pump housing moving up with the lift member; a discharge pump moving up with the pump housing to pump the first and second contents mixed with each other; and a push button coupled to the discharge pump to be movable up or down and formed with a discharge outlet.

A pump dispenser has a pump body and a reciprocable plunger with a lock-down mechanism, comprising internal or external lock formations of the plunger and body, such as thread formations, by which the plunger can be locked down for shipping and released subsequently by a rotational release movement. To supplement security for demanding shipping conditions the dispenser also has a supplementary catch mechanism in which respective catch formations of the plunger and body engage selectively in the locked-down position to inhibit the rotational release movement. The catch formations may have circumferentially-directed surfaces which engage between the underside of a plunger head having a shroud and a nozzle and the top of the body beneath the plunger head. They can be released by resilient deformation of one or more of the catch formations.

A dispenser for viscous products, including: a container for a product, a sealing cap designed to be screwed onto the container, a pipette, and a piston capable of causing a suction of the product into the pipette, the dispenser being arranged such that, when the cap is screwed onto the container, the unscrewing of the cap in the direction of opening of the dispenser causes, by itself, a movement of the piston producing the suction.
