The device is based on a metering chamber which is designed to be screwed onto a tube and which has inlet and outlet openings for the product. The product is dispensed by a plunger displaceable in the metering chamber. An axially displaceable plate valve is arranged between the plunger and the bottom of the metering chamber. The valve plate is provided with holes for the passage of product. The plate valve functions such that the valve plate closes the outlet opening during filling of the metering chamber and the inlet openings during emptying of the metering chamber. The dispenser may be screwed onto standard commercial tube packs for the application of salves or pastes.
A deformable spray dispenser comprises a valve unit which is capable of axial displacement within the container with respect to the container cover between a spray-discharge position and an air-suction position. The valve unit supports a member for shutting-off the eductor tube in its air-suction position. The valve unit is provided with a valve cap having an external face which is applied against an internal face of the container cover in the spray-discharge position and cooperates with the internal face so as to form a nozzle for discharging liquid through the container-cover orifice in an atomized spray pattern.
Apparatus for dispensing predetermined amounts of viscous product. The apparatus has a conduit which is telescopically received with a cap. The cap and conduit define an expandable dosing chamber which expands to a predetermined maximum volume when product is introduced into the chamber through the conduit. A check valve prevents back flow of product through the conduit. Collapsing the chamber from its maximum volume to a minimum volume dispenses the product from the dosing chamber.
A dispensing unit for a threaded neck bottle including a dispensing nipple, valve assembly, and a connector. The dispensing nipple is squeezable and mostly cylindrical in shape with one end converging. The bottom of the converging end is open so that the fluid contained within the dispensing nipple escapes when the nipple is squeezed. The valve arrangement is disposed inside the convergent end of the dispensing nipple and includes a rod connecting a ball valve at its bottom and a truncated cone shaped member at its other end. The connector secures the neck of the storage bottle to the dispensing nipple and includes outer and inner concentric cylinders secured to and made an integral part of an annular ring having an outside diameter and an inside diameter about the same diameter as the first and second concentric cylinders. The annular ring seals one end of the space between the cylinders. The inside of the outer cylinder is provided with threads for threadably receiving the top of the dispensing nipple into the side of the connector away from the annular ring. The inside of the inner cylinder is provided with internal threads to threadably receive the threaded neck of the storage bottle inserted from the side of the annular ring away from the concentric cylinders. The lower end of the internal concentric cylinder is provided with a seat which mates with the truncated cone shaped member within the dispensing nipple to seat when the condiment bottle is inverted.
The present invention is directed to a metered dispensing cap system for containers such as tubes and the like. The system has a base element which is attachable to the neck of a squeezable container and which has a sidewall portion and a top. The base element has an opening in the top for outflow of a material from a squeezeable container into a meter element. This base element may be removeably attachable, e.g. by being screwed on, or may be permanently attached, e.g. by being integrally molded with the container. A one way valve is located in the opening of the base element to permit the flow of material from a container through the opening while preventing backflow. The system also includes a meter element which acts like an inverted trap and which has a sidewall portion and a top with an opening in the top for dispensing of the material therefrom. The sidewall portion of the meter element is slightly larger than and has the same across section shape as the sidewall portion of the base element and this sidewall portion of the meter element is higher than and located about and encompasses the sidewall portion of the base element. Further, the meter element is vertically slideable along the sidewall portion of the base element with an upward position for receiving a volume of material in a pre-determined amount when the squeezeable container is squeezed and downward position whereby the opening in the top of the meter element allows for dispensing of the desired amount of fluid when the meter element is pushed down.
A gusseted envelope or box making apparatus and method including the use of a tractor feed unit (11) which perforates the web stock (5) prior to a subsequent printing step capable of printing on either side of the web (5). At least one thermal print head (61) precisely activates thermal ribbon (57) which is accurately registered with the web (5) by means of pin feed holes (16,17). A product conveyor (74) manipulates the product (75) so as to automatically load the box or envelope (69) thus manufactured and printed. A multipart form (141) is disclosed including a continuous envelope (167), return reply envelope (173) and enclosed coupon (166) which may all be imprinted with unique customer information (161). The complete form (141) is folded and inserted into a parent envelope (167) by a series of vacuum plates (376) and insertion rams (392).
