A cream holding tube of molded plastic. This tube includes an automatic valve portion at the forward end which when the rear of the tube is squeezed will open due to cantilevers and a bellows portion. When pressure is released from the body of the tube, the accordion like portion of the valve will cause the opening to close.

A valve mechanism for a tube-type fluid container includes a valve seat portion having an upper opening portion and a lower opening portion; and a valve portion disposed co-axially with the upper opening portion. The valve portion includes a supporting portion attached at or below the lower opening portion, a closing portion for closing the upper opening portion, and a connecting portion connecting the closing portion and the supporting portion. At least either the closing portion or the connect...

A dosing head (1) includes a dosing chamber (30), of axis X, inside which a piston (21) is slidably fitted, a first surface (31) of which is in communication with the interior of a container and a second surface (25) of which is in communication with the dosing chamber (30). The piston (21) is fitted so as to be able to pass from a first position in which the dosing chamber (30) has a maximum volume to a second position in which the dosing chamber has a minimum volume. The dosing chamber (30) in...

Dispenser for dispensing a liquid, in particular a drug, such as for instance eye drops, which dispenser comprises two half portions which can be assembled by means of a snap lock to form a closed chamber adapted to surround a plastic bag containing the liquid, said bag having a constricted portion into which the reservoir of the bag extends, the constricted portion forming a neck with a dosage duct, through which the liquid, after breaking of the constricted portion, may be squeezed by compress...

A dispensing device for flowing substances comprises a tube (19) of flexible material adapted to receive the substance in question from a conduit (13) and a valve arrangement (20) for regulating flow of substance from the tube out through a discharge opening (21). The valve arrangement has two or more valve parts (23), which are adapted to each other so as to in a first relative position shut the flow past the valve and in a second relative position open for flow therethrough. A cooling device (...

A squeeze container has a flexible and resilient sidewall and a top mouth closed by a cap through which a measuring tube extends into the container to terminate adjacent the container bottom wa1. A normally-closed check valve is fitted to the tube bottom end to allow liquid in the container to enter the tube in a measured quantity when the side wall is squeezed and for retaining the measured quantity of liquid when the tube sidewall is released. The measured liquid in the tube is discharged when...

Disclosed are closure mechanism for the open-neck of manually resiliently squeezable receptacles permitting fluids of a wide viscosity range to be dispersed through the open-neck only so long as manual pressure is being exerted against a visually indicated portion of the receptacle deflectable wall. The dispensing closure mechanism generally includes: a cap for the receptacle open-neck and having an outlet-opening; an elongate spindle within the receptacle along the central-axis thereof, the spi...

Containers, particularly insulated containers are disclosed consisting essentially of a container body filled with a pump mechanism and featuring a flexible bell shaped member, immersed in liquid and equipped with disc valve. This bell shaped member is compressed whenever the actuating button is pressed, thereby forcing the liquid contents of the container to flow out through the pipe up to the pouring spout. A flexible tube is automatically squeezed shut when the bottom returns to its uppermost...

A fluid dispensing device having a container with a collapsible body section and an upper neck which is adapted to receive therein a dispensing head which is automatically self-closing. The dispensing head has a housing defining a dispensing channel vertically therethrough in which a valve is positioned having a valve head for abutting a valve seat defined in the upper portion of the dispensing channel and a valve stem extending downwardly to a valve flange. A resilient member is secured to the ...

An automatic closure for collapsible tubes, squeeze bottles, and the like containers of the type formed from resilient plastic material. The container typically is tubelike, provided with a tapered or frusto-conical neck portion terminating in a flattened mouth defining end lips forming an openable closure. Pressure applied to the body of the container remote from the lips to forms a transverse pinch-off across the end portions wherein the lips are deflected or bent along a line of curvature to ...
