AI Technical Summary

Technical Problem

In the prior art, containers equipped with non-removable dispensing pumps cannot be effectively refilled, resulting in resource waste and environmental pollution.

Method used

By positioning the bottom of the container at the lower side, the internal pressure of the refill cylinder is gradually increased and decreased using a pump piston and air channel, allowing liquid to flow from the refill cylinder to the container. Air is then expelled from the container through the air channel. This process is repeated until the target filling volume is reached.

Benefits of technology

It enables efficient container refilling, reduces resource waste and environmental pollution, is applicable to a variety of container designs, and optimizes the refilling process through personalized identifiers and management systems.

Abstract

A method for refilling a container (26) with a dispensing pump fitted on the neck (7) of the container, comprising the following steps: [1] placing the container (26) right side up and fluidly connecting the inside of a refill cartridge (30) having a refill liquid with an air passage (22) present in the pump, and, at a certain position of the piston (11) of the pump, the air passage communicates the inside volume (8) of the container with the outside, [2] moving the piston until fluid communication is established between the inside of the refill cartridge and the inside volume (8) through the air passage, [3] increasing the pressure under which the liquid in the inside of the refill cartridge is subjected, thereby causing part of the liquid to pass through to the inside volume, thereby increasing the pressure in the inside volume, [4] reducing the pressure in the inside of the refill cartridge to a value lower than the pressure in the inside volume, thereby allowing air to pass from the inside volume to the inside of the refill cartridge through the air passage, [5] repeating steps [3] and [4] at least once, [6] disconnecting the refill cartridge.
