PURPOSE:To eject through an ejecting orifice in an appropriate amount possible for contents and make a container disposable after using up of the contents by a method wherein a spirally structure reciprocating device for pressing the rear-side part of a flow rate adjusting body is porovided while the flow rate adjusting body made of a soft elastic material is proided to a ejecting passage communicating wiht the ejecting orifice on an ejecting head is provided, and thereby the flow rate in the ejecting passage is adjusted. CONSTITUTION:Even through properties and kinds of pressurized gas are changed, appropriate conditions can be secured for ejecting with a spirally structure reciprocating device 14 for pressing the rear-side part of a flow rate adjusting body 5 operated on occasion of every change. As the flow rate in the ejecting passage 3 provided to the flow rate adjusting body 5 made of a soft elastic material interposed in the jet passage 3 leading to the ejecting orifice 2 on the ejecting head 1 can be adjusted, appropriate adjustment is possible for the flow rate. Grooves 10, provided to the surface of the flow rate adjusting body 5, are extended or reduced, enabling contents to be ejected in an appropriate amount through the ejecting orifice 2 of the ejecting head 1 together with the pressurized gas, and the contents can be consumed sufficiently even through the pressure inside the container decreases. The container can be made disposable without providing any of explosion-preventing devices. |
