摘要： Disclosed is a tubeless dispenser container. A tubeless dispenser container according to one aspect of the invention is a tubeless dispenser container for dispensing a content held in a filling space and includes: a bottle part in which the filling space is formed and which has a supply hole, for allowing a flow of the content, and an air hole, for allowing an inflow of air, formed in its upper surface; a connector part coupled to an upper portion of the bottle part to spatially separate the supply hole from the air hole; and a pump part that is secured to a designated position of the connector part and configured to suction and dispense the content supplied through the supply hole, where a supply channel connecting a lower portion of the filling space with the supply hole may be formed in the bottle part.

摘要： In exemplary embodiments of the present invention, various novel dispensing devices can be provided. Such devices can involve a range of sprayer heads and sprayer/foamer systems incorporating such heads. Novel sprayer/foamer heads can include buffers of various types. By using a buffer, a user need not continually be pumping the device in order for the device to be spraying or foaming. In exemplary embodiments of the present invention, such a buffer can be spring loaded, spring loaded combination, elastomeric or gas. In exemplary embodiments of the present invention, the buffer can be in line or adjacent to a piston chamber. If adjacent, it can be connected to the piston chamber with a one way valve, to provide for spray after a downstroke of the piston has been completed, or without, to allow spraying to cease once a user releases the trigger or other actuator. In exemplary embodiments of the present invention, such novel sprayers and foamers can be mounted upside down, in various “Flairomop” devices, used to clean floors or the like. When using a buffer, a piston chamber can be designed to deliver greater amount of liquid per unit time than can be possibly dispensed through the nozzle or nozzles. The fraction of liquid that cannot be sent through the nozzle(s), due to their inherent restriction, can thus be sent to the buffer for dispensing after the piston downstroke has been completed. A volume of the piston chamber, a volume of the buffer, a pressure response of the buffer, the throughput of the nozzle, and the minimum opening pressure of the outlet valve can be arranged to restrict the outlet pressures of liquid droplets exiting the nozzle within a defined range.

摘要： A dispensing device includes an air inlet hole passing through a cylinder in its thickness direction to connect an internal space of the container to an external space; and an action valve fitted onto an outer circumferential surface of the cylinder to close the air inlet hole, and that is isolated from the outer circumferential surface of the cylinder to introduce external air to the container when an internal pressure of the container is lower than an external pressure. An upper end portion of the cylinder is diametrically larger than a lower end portion. The action valve includes a ring-shaped annular section; and a valve section that extends axially from the annular section to close the air inlet hole while maintaining a radial clearance from the air inlet hole, to shield the air inlet hole from the internal space of the container.
