Abstract: An interlocking plastic display has a first member formed as a first shot of an injection molding process. The first member includes a submerged grid system which is formed only where necessary to connect otherwise unconnected portions of the top layer or to stabilize the top layer where openings may be relatively large. An array of spacers is formed beneath those portions of the top layer having material therein, to space the top layer from the bottom of the mold used during a second shot of injection molding. No spacers are formed beneath completely spaces of the top layer in which no material is disposed. The arrangement of the spacers provides an open area underneath the top layer, so that the second member may be formed in the second shot and allows the second shot material to flow around the spacers on the bottom of the mold to interlock the two members.

Abstract: A display device has two interlocked contrasting elements. A display element includes indicia and a first locking member. The background element includes a second locking member complementarily shaped to conform to the shape of the first locking member. The first locking member has two portions. The first portion is a waffle plate which tapers from top to bottom. The second portion includes a plurality of frusto-conical pads disposed beneath nodes of the waffle plate of the second portion.

Abstract: A fixture for fluid dispensing bags having lower portions with nozzles. The bags are used with the lower portions folded forwardly and the nozzles pointed downwardly. The nozzles form keys which differ for different groups of the bags. The fixture has a forwardly extending shelf for the lower portions of the bags and in which a hole is formed and an insert is positioned in the hole and has a nozzle hole forming a key hole fitted by the nozzles of only one group of the bags.

Abstract: A fixture for a bag-type liquid dispenser has a bracket having an upstanding plate for attachment to a wall and from the bottom of which a shelf having a nozzle hole extends forwardly, and a cover adapted to open and close in front of the plate and shelf. The dispenser has a flexible bag in which the liquid is sealed and having a main portion in front of the plate and a dispensing portion folded forwardly on the shelf and having a dispensing nozzle extending downwardly through the nozzle hole. The cover has a forwardly extending portion covering the bag's forwardly folded dispensing portion, an opening being formed in this forwardly extending portion above the actuator, and a push button being positioned in this opening for applying pressure on the valve's actuator.

Abstract: A display device has two interlocked contrasting elements. A first element is of a first color, and has a top surface configured to resemble desired indicia, e.g. one or more letters or numerals. The first element also has a bottom surface which includes a plurality of first locking members. A second element has a plurality of second locking members which interlock with the first locking members, and is of a second color. The second color preferably contrasts with the first color. The interlocking action of the first locking members with the second locking members serves to interlock the two contrasting elements, thereby providing a good mechanical locking action therebetween. In a first embodiment, the first and second elements together form a generally flat top surface, while in a second embodiment, the two elements are of different top levels, so that the indicia may be either raised or recessed with respect to the background.

Abstract: A dispensing device for a bag container a liquid, made of flexible material and forming upper and lower walls through which holes are formed for receiving the device, has a tubular lower part with a top flange which is sealed to the inside of the lower wall and depends through the hole in the lower wall. A tubular upper part has a top flange sealed to the inside of the upper wall and depends through the hole in that wall and is telescoped inside the lower part so as to move up and down in the lower part. The top of the upper part forms a piston such as a collapsible dome extending upwardly through the hole in the upper wall and exposed on the outside of the upper wall and therefore exposed on the outside of the bag. The lower part has a lower end having a self-closing valve and has at least one side port normally open to a space between the flanges and therefore between the bag walls.

Abstract: A wall fixture containing a liquid dispenser, the fixture comprising a bracket having an upstanding plate from the bottom of which a shelf having a nozzle hole extends forwardly and a cover adapted to open and close in front of the plate and shelf, the dispenser comprising a flexible bag having front and back walls containing the liquid and having a main portion with its back wall suspended in front of the plate and a dispensing portion folded forwardly on the shelf so as to form a lower wall, the lower wall having a dispensing valve having a dispensing nozzle extending downwardly through the nozzle hole, and a depressible upper wall above the valve, the valve having an operator between the upper and lower walls and actuated by pressing the upper wall downwardly on the operator; the cover having a pressing arrangement for pressing a bulge in the bag's front wall and extending towards the bag's back wall at a position above the bag's dispensing portion and so as to form a passageway on at least one side of the

Abstract: A liquid dispenser includes a flexible bag, an enclosing box and an actuator. The bag is formed with two chambers, a supply chamber and a discharge chamber, and a hole through which the actuator moves. The discharge chamber has a discharge member which is acted upon by the actuator to dispense a measured discharge. The bag is suspended in the housing with the discharge chamber folded relative to the supply chamber.

Abstract: A flexible-bag self-closing metering dispensing valve for a flexible bag containing a fluid product, has a collapsible dome with an entrance for the product, and a valve seat supported by spokes, below which a diaphragm is positioned with a hole having a periphery seated on the valve seat. The spider and seat and the diaphragm are mounted so they cannot be driven out by sudden depression of the collapsible dome.

Abstract: A self-closing squeeze bottle dispensing valve includes a vent for venting the bottle after squeezing. The valve is made with a cap which can be rotated so as to positively shut-off not only the valve's dispensing orifice, but also its vent, the two shut-offs being simultaneous.

Abstract: Hollow shapes are blow molded with a special form of gate connecting the shapes to the parison from which they are blow molded and permitting subsequent degating of the shapes by ultrasonic mechanical vibration applied to the gates.

Abstract: A pill box has a sliding cover for a bottom part having a rim on which an elastically compressible gasket is positioned, providing moisture-proofness. By a programmed squeezing together and sliding action the cover may be slid from the bottom part to gain access to the box's interior, the programmed actions making the box child-resistant. The gasket functions both as a seal and as a spring which keeps the cover and bottom part biased apart.
