PUMP DISPENSER - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240050970 titled 'PUMP DISPENSER

Simplified Explanation

The abstract describes a pump dispenser for metered removal of liquid from a container. The dispenser includes a housing, a rising tube, a pump head, a piston, a dispenser opening, a spring, and a valve.

  • The housing is placed on the container to form a metering chamber.
  • The rising tube is connected to the metering chamber.
  • The pump head is movable along the longitudinal axis of the dispenser to carry out a pump stroke.
  • The piston, secured to the pump head, conveys the liquid in the metering chamber.
  • The dispenser opening is connected to the metering chamber for the liquid to leave the dispenser.
  • The spring resets the pump head relative to the housing.
  • The valve controls the conveying direction of the liquid and blocks the opposite direction.

Potential applications of this technology:

  • Pharmaceutical industry for precise dispensing of medications.
  • Cosmetics industry for controlled dispensing of beauty products.
  • Food industry for accurate measurement of ingredients.

Problems solved by this technology:

  • Ensures accurate and controlled metering of liquid from a container.
  • Prevents backflow or leakage of the liquid during the dispensing process.

Benefits of this technology:

  • Precise and consistent dispensing of liquid.
  • Reduces waste and ensures cost-effective use of the liquid.
  • Easy to use and maintain.
  • Suitable for various industries requiring metered liquid dispensing.


Original Abstract Submitted

a pump dispenser for metered removal of a liquid from a container includes a housing for placement on the container to form a metering chamber, a rising tube connected to the metering chamber, and a pump head movable relative to the housing along a longitudinal axis of the dispenser to carry out a pump stroke. the pump dispenser has a piston secured to the pump head that is movable in the metering chamber to convey the liquid, a dispenser opening is connected to the metering chamber through which metered liquid can leave the pump dispenser, a spring that resets the pump head relative to the housing, and a valve that defines a conveying direction of the liquid from the rising tube into the dispenser opening and that blocks a conveying process in the opposite direction. the spring has a plurality of rings connected by respective connecting webs.
