Description

    Technical field of the invention
  • The present invention describes a portable dispenser suitable for generating a flow of pressurised liquid without needing to use any energy source.
    • Background of the invention
  • It is known that in order to generate a flow of liquid it is necessary to have a pressure difference between two points. The pressure difference is obtained by means of pumping groups that work with electric energy, but in places where there is no connection to the electrical grid the use of generators is necessary. Generators are difficult to transport and require the use of fuels.
  • It is also known that vessels for water must be sanitised, because bacteria and mould proliferate in the corners of the vessels, especially in damp environments.
  • Likewise, metal containers rust, depositing particles in the bottom of the container.
  • A person skilled in the art knows different means to achieve the seal in the vessels, such as for example threading, welding or screws.
  • The document closest to the invention is ES1098105 U which describes a device for accumulating pressurised fluid. The device comprises a sealed container with a deformable bag. The deformable bag contains a pressurised fluid and the container contains a pressurised gas housed between the walls of the device and the deformable bag. bag. ES1098105 U discloses the preamble of independent claim 1.
  • The device described by ES1098105 U is suitable for obtaining a flow of liquid without any energy source. However, the use of the device can produce contaminated liquids or water when the deformable bag breaks. If the deformable bag were to break, the water would fall due to gravity to the bottom of the device, remaining accumulated. The accumulated water will produce the proliferation of microorganisms. Upon refilling the device, the clean water will be contaminated by the accumulated water.
  • The device of ES1098105U does not enable the replacement of the deformable bag.
  • Document US5911520A1 refers to a portable water shower apparatus that comprises a pressure vessel capable of withstanding an internal pressure of at least about 50 psig (3,45 bar).
  • The vessel, which may be sized to hold from about 1 (4,40l) to about 2¼ gallons (9,91 l) of water, is formed having an liquid filling and emptying opening and a combination handle and manual pressurizing pump which seals the opening against pressure loss when the vessel is pressurized. The vessel has a pressurized fluid outlet fitting and the apparatus includes an elongate liquid discharge conduit which is detachably attached to the vessel outlet fitting and which has a manually-operated shower head attached to the distal end of the hose for controlling the flow of pressurized liquid from the vessel. A conventional valve stem is provided for the vessel enabling the vessel to be pressurized by use of a CO2 device available in bicycle shops. A pressure relief valve is mounted to the vessel to prevent over-pressurizing the vessel. Temperature and pressure gauges are provided as is a manually-operated valve for venting pressure from the vessel. An insulating cover, having an attached pouch for carrying articles, is installed over the vessel.
  • Document US3080568A1 refers to a portable shower bath assembly comprising a water tank, means to admit water into said tank, conduit means connecting the lower portion of said water tank to a sprinkler head, means to seal said water tank, and an air inlet check valve on the top of said tank, whereby air may be pumped into the upper portion of the tank to develop a pressure sufficient to force the water in the tank through said conduit means for discharge at said sprinkler head.
  • Document GB2333129A refers to a dispenser having a collapsible, liquid impermeable container 4, e. g. a bag or pouch, and an extraction arrangement, e. g. with a hand actuated trigger pump, for extracting liquid from the collapsible container 4 and dispensing the liquid as a spray. A seal is arranged to prevent air ingress into the collapsible container 4. The seal and extraction arrangement being such that the extraction arrangement is operable to dispense the liquid whilst the seal is in the sealing position. The collapsible container 4 collapses as liquid is dispensed, resulting in little or no back pressure (vacuum) existing in the flexible collapsing container; this inhibits ambient air being drawn into the collapsible container. The dispenser is thus suitable for spraying sterile or reactive fluids, e. g. in clean room environments such as hospitals, pharmaceutical or food preparation areas.
    • Object of the invention
