A spray pump comprising a small piston and an upper pump rod with a liquid accumulation cavity is provided. The upper pump rod is provided with a liquid discharge hole communicates with the liquid accumulation cavity, and the small piston is provided with a sealing column for sealing the liquid discharge hole. A central column is provided with an ejector rod extending into the liquid discharge hole, and a liquid flow gap is disposed between the ejector rod and the liquid discharge hole. A central hole communicates with the liquid discharge hole is disposed at a central part of the central column, and a press head with a lower part being fixed with the central column. A press plate is fixed with the upper pump rod, and a press gap is disposed between an upper side of the press plate and a lower side of the press head.

A spray canister device includes a canister element containing a sprayable solution and a sleeved cover element. The sleeved cover element includes a sleeve portion having a first end and a second end opposite the first end, a handle grip extending from the second end of the sleeve portion, a projection extending from the sleeve portion, the projection disposed on a side of the sleeve portion opposite from the handle grip, and a cap portion extending form the first end of the sleeve portion. The cap portion having a body portion, a cut-out portion including an opening configured to spray the solution, and a channel disposed within the body portion. The channel forming a conduit between an outlet of the canister device and the opening.

A method and apparatus is provided for spraying a solution, such as a cleaning solution a barrier material, out of a spray canister device to a surface area of a human body. The spray canister device generally includes a removable sleeved cover element covering an inner canister element. The spray canister device with the removable sleeved cover is easy to carry and easy to spray, and can be handled manually or functions together with other devices.

The disclosure relates to a fluid dispensing device comprising: a housing comprising an orifice and configured to accommodate a portion of a spray delivery device comprising an outlet, a protective cap configured to accommodate the outlet of the spray delivery device and comprising a cap portion, wherein the protective cap is configured for fitting to the housing so that the cap portion covers the orifice, a biasing member transferable between a pre-loaded state and an unloaded state and configured to store energy in the pre-loaded state to produce a discharge of the spray delivery device, a releasable interlock configured to retain the biasing member in the pre-loaded state, a trigger engaged with the interlock and configured to release the interlock when actuated, wherein release of the energy stored in the pre-loaded biasing member is prevented as long as the cap portion covers the orifice.

A cleaning device includes a cartridge assembly, a hose/tubing, a nozzle, and an activator. The cartridge assembly includes at least one cartridge configured to hold a liquid solution. An attachment device is coupled to the cartridge assembly and is configured to secure the position of the cartridge assembly to a user's arm adjacent the hand. A pump is located within the cleaning device and is located between cartridge and the nozzle, such that pump regulates dispensing of the liquid solution. The nozzle is in communication with the pump and acts as a diffuser to adjust the stream of the liquid solution passed through the hose from pump. The activator is in communication with the pump such that operation of the activator selectively releases a volume of the liquid solution from the cartridge so as to pass through the nozzle. A control unit and interface are permitted.

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.

A method and device for indicating whether a dispensable product will require refilling prior to the next scheduled service interval includes tracking the amount of use over a first interval, and calculating a frequency based from the use over the first interval. The quantity remaining is compared with the required amount, which is the product of the number of weeks in the service interval and the calculated frequency. Thus, when the quantity remaining is less that the required amount, a warning will be provided to indicate that the dispensing product should be replaced, as it will be empty before the next service interval.

A multi-chamber applicator (1) comprising a multi-chamber container (4, 5) for storing at least two subcomponents (A, B), having a device (3) for removing a mixture of the subcomponents.

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.
