A dispenser system for a canister. The system includes an actuator and a cover that can prevent inadvertent actuation. The actuator may include a button, a stem connector and an actuator housing. The stem connector may include wings with a protrusion to create a snap-fit with the actuator housing, thereby holding the stem connector in place during operation of the dispenser system.

A dispenser for dispensing a liquid or pasty compound that has a dispenser head which has a dispenser opening and a dispenser lower part, a storage chamber, and a pump device in the dispenser head. The compound can be dispensed out of the storage chamber via the dispenser opening by the pump device. The storage chamber is additionally produced as a bag-like storage chamber part and is received in the dispenser lower pat in a replaceable manner. The storage chamber part has an adapter part for interacting with the pump device in order to conduct the compound, and the adapter part has a cover element which can be acted upon in order to form an opening of the storage chamber. A seal wall which extends so as to surround the cover element is suitable for sealingly interacting with the dispenser.

In exemplary embodiments of the present invention, “Flairosol” dispensing devices can be provided. Such devices utilize a combination of Flair® technology, pre-compression valves and aerosol-like pressurization of the dispensed liquid. Such a dispensing device has, for example, a main body comprising a pressure chamber, the latter being provided with a pressure piston and a pressure spring. The device further has a piston and a piston chamber which draws liquid from a container, for example, the inner container of a Flair® bottle, and fills the pressure chamber with that liquid as a user operates a trigger in various compression and release strokes. The piston chamber has both an inlet valve and an outlet valve, which serve to prevent backflow. Liquid exiting the piston chamber under pressure (supplied by, a user pumping the trigger) enters a central vertical channel which is in fluid communication with both the pressure chamber (above the pressure piston) and a dome valve provided near the outlet channel at the top of the dispensing head. The dome valve has a preset pressure, such that once exceeded by the liquid, opens and allows for a spray. If the liquid pressure drops below such preset pressure, the dome valve closes off the outlet channel, which serves to regulate the strength of the flow and preclude leakage. Alternatively, in an activated embodiment, for example, once the liquid is sufficiently pressurized, it can be dispensed by a user allowing the dome valve to open by pressing on an activation button that removes a dome lock.

A dispensing device including a bottle provided with a neck and a trigger dispensing head fitted to the neck is provided. The dispensing head includes a socket at least partially housed in the neck compartment, a main body that, with the socket, delimits a valve compartment in the neck, a valve group, a piston, a chassis, a trigger group, and elastic return elements. The valve group is contained in the valve compartment, limiting the overall size of the device.

The present invention relates to vacuum pump, to the extent that the difficulties of putting similar products in automatic assembly and production and the technical issues of carrying out one-piece plastic production, assembly and recycling would be resolved. A pump core assembly, the pump body of the pump core assembly is provided with an elastic sleeve, the inner diameter of the upper plug of the first inner plug outwardly of the pump body is provided with a lower elastic cavity that is larger than the inner diameter of the plug, the inner diameter hole of the upper plug of the first inner plug is provided with the upper elastic cavity of the outer diameter of the first valve stem whose outer diameter is smaller than the inner diameter of the upper plug. The spring is substituted by the first plastic spring, the said first valve stem is substituted by the second valve stem, or the said large ring is substituted by an inner ring, an outer guard and a rotating ring, the spring is substituted by the second plastic spring.

A dispensing device for paste products, including toothpaste, is provided. The dispensing device includes a container, a pumping diaphragm and a head applied to the container. The head is equipped with a tube and a button for acting on the diaphragm and deforming it for dispensing. The button has a pressure surface for a user's dispensing action. An extension element which, in an active position, is arranged as an extension of the pressure surface of the button, increases a leverage effect.

An apparatus and a method are provided for a sprayer nozzle support to a pump mechanism of a trigger sprayer assembly. The sprayer nozzle support generally comprises a tower portion and a first and second side protrusions. The tower portion is configured to convey stability to the pump mechanism when a screw cap of the trigger sprayer assembly is screwed onto a neck of a container. A top of the tower portion is configured to support the pump mechanism and a bottom of the tower portion is configured to contact the screw cap. The first and second side protrusions provide structures whereby the sprayer nozzle support may be removed from the trigger sprayer assembly. A curved proximal surface of the tower portion and the first and second side protrusions facilitates an unobstructed grasping of the trigger sprayer assembly in a hand.

A dispenser for dispensing a flowable product from a container has a pump module mounted on the container at an opening thereof. The pump module includes a pump body, which defines a pump chamber and a pump chamber inlet for product to flow from the container interior into the pump chamber. A pump actuator is operable in a pumping stroke relative to the pump body to vary the volume of the pump chamber and dispense the product. The pump includes a movable body portion which is operable in a displacement stroke into the container. The movable portion has a displacement body with a product-engaging face directed onto an interior product space of the container upstream of the pump chamber inlet, to assist priming. Below this a disrupter member, a grid of narrow bars, projects to penetrate the product.

A dispenser container having a retractable nozzle is proposed. The container is configured such that an air pumping part (30) is coupled and secured to an upper portion of a container body (10) by a locking cap (20), a guide cap (20) configured to be movable up and down is coupled to the outer surface of the locking cap (20) at a location outside the locking cap, and a nozzle cap (50) configured to pressurize and operate the air pumping part while being rotated and being moved up and down in conjunction with the guide cap is coupled to an upper portion of the guide cap (40) at a location outside the guide cap so that the nozzle (60) coupled to the nozzle coupling hole formed at the side of the nozzle cap is extended and retracted in response to the rotation of the nozzle cap.

A dispensing device for paste products, including toothpaste, is provided. The dispensing device includes a container, a pumping diaphragm and a head applied to the container. The head is equipped with a tube and a button for acting on the diaphragm and deforming it for dispensing. The button has a pressure surface for a user's dispensing action. An extension element which, in an active position, is arranged as an extension of the pressure surface of the button, increases a leverage effect.
