Abstract:
A portable fuel container is disclosed that includes a paddle actuator that is depressible into an engaged position, whereby fluid may only be removed from the container while the paddle actuator is being depressed.
Abstract:
The invention relates to a spill proof self-closing flow control device (SCFCD) with adjustable actuator element for flexible or rigid containers with fluids. The SCFCD comprises a spout (2), a flexible valve-retaining element and a container closure element (12). The valve-retaining element is a one-part component consisting of an actuator element (9), a cylindrical valve holder (11) and a valve (10) for alternately opening and closing the flow-through orifice. In the various embodiments two or three pressure chambers are formed with pressures P1, P2 and P3 controlling the flow control device, separated by the valve- retaining element. In a first, second and fourth embodiments the actuator element is configured to move the valve in the downstream direction by an under pressure in the first chamber thereby bringing the valve in the open position, while in a third embodiment, the actuator element opens the valve in the upstream direction. Provisions are foreseen to increase the fluid outflow from container by externally adjusting the opening/closing force of the actuator element.
Abstract:
A closure element (10) for a fluid container (100) comprises a fluid pathway (20) having a first open end (21) and a second open end (22). The first open end (21) is adapted to be in fluid communication with the fluid container (100). A sealing element (30) is located in the fluid pathway (20) at its second end (22) and is moveable within the fluid pathway (20). A locking element (40) having an exit aperture (41) is adapted to fit over the second open end (22) of the fluid pathway (20). The locking element (40) is moveable with respect to the fluid pathway (20) between a locked position and an unlocked position. Furthermore, the application relates to a two- compartment fluid container (100).
Abstract:
A device for storing and dispensing a substance includes a container having a body defining therein a storage chamber for receiving and storing the substance. The container includes a head located at one end of the body and a first passageway that is in fluid communication with the storage chamber of the body and defines a flow path therebetween. The container also includes a pierceable wall located on an opposite side of the passageway relative to the storage chamber, and a first connecting portion for connecting another component thereto. The device also includes a one-way valve assembly that includes a valve body including a body base defining a second passageway and at least one piercing portion engageable with the pierceable wall of the container. The valve assembly includes a second connecting portion that is connectable to the first connecting portion of the container for fixedly securing the valve assembly to the container.
Abstract:
The present invention is directed toward molded plastic re-sealable closures (1, 31) for use with a fluent dispensing container (2). The closures (1, 31) each have a rupturing member (12) and a cover (19) on whose initial opening causes the rupturing member to tear a tearable sealing to form a generally rectangular fluent exit aperture (4), and secures the torn away material remote from the fluent exit aperture to prevent it from blocking same during subsequent re-openings and re-sealings. The present invention is also directed to screw cap assemblies (41, 61) similar to the closures (1,31) but each having an axially displaceable puncturing member and a cap on whose initial unscrewing causes the puncturing member to puncture a tearable sealing to form a generally circular fluent exit aperture. The present invention is further directed to toggle cap assemblies (71, 81) for use with a hand squeezable plastic bottle, the toggle cap assemblies each including a latchable arrangement disposable from a sealing position for preventing the dispensing of a bottle's contents to a flow communication position for enabling the dispensing of a bottle's contents on squeezing the bottle, and vice versa on applying a force against an exposed surface of the latchable arrangement in the direction of the bottle's interior. The present invention is still further directed to a collapsible plastic bottle (91), and a dual container dispenser (101).
Abstract:
A valve for dispensing the fluid contents of a container such that external contaminants such as dust, air or microbes cannot enter the container even after repeated dispensing cycles. The valve comprises a plug-type valve and an elastomeric sheath type valve such as a flapper valve, slit valve, or duck bill valve. All are one-way devices. The plug is provided with a means for resetting it to the closed position at the end of each delivery cycle such that the plug is a one-way device also. The means can be an elastomeric tether, gravity, or the deformation of a valve part. The plug can be provided with channels or other cut or shaped features, e.g. grooves, to facilitate fluid flow. The container used with this invention must be volumetrically reducible and thereby maintain its own internal pressure at the end of a delivery cycle. Alternatively, the valve of the present invention can be made without the outlet valve, i.e., the flapper, slit, or duck bill valve. In this case, the plug is the only one-way valve, mechanism.
Abstract:
A dosing cap is set on the product outlet of a container for pourable substances having a closable product outlet pipe with a pouring spout. In order to prevent the product from adhering to and soiling the cap, and at the same time to make it possible to accurately dose small amounts of product, a valve body (10) is arranged in the product outlet pipe (2) and cooperates therewith. In its closed position, the valve body (10) completely closes the product outlet pipe (2) and when the pressure changes in the container, its open or closed position is changed.
Abstract:
A thin film beam spring valve (21), a method and apparatus for assembling it are provided. The thin film beam spring vent valve (21) is provided in a squeeze pump package (22). The package includes an outer resilient bottle (22) and a flexible bag (24) with a relatively rigid fitment (30). The outer resilient bottle (22) is provided with a substantially cylindrical internal surface portion and an aperture (58) to enable fluid communication between the interior and the exterior of the outer bottle (22). The valve (21) includes a thin film beam spring (60) located adjacent the aperture (58) such that the beam spring (60) will seal the aperture (58) upon exposure to a positive dispensing pressure within the bottle (22). The beam spring (60) will allow air to enter the bottle (22) upon the application of negative pressure within the bottle. An automated mechanism is provided for cutting and grasping (e.g., utilizing a vacuum mandrel) a beam spring comprising a predetermined length of a band of flexible material. The vacuum mandrel is then inserted into the bottle adjacent the substantially cylindrical internal portion such that upon release of the vacuum the beam spring expands against the substantially cylindrical internal surface of the bottle such that central portion of the beam spring is adjacent the aperture. A method and apparatus for inserting the flexible bag into the outer bottle of the squeeze pump package is also provided.
