摘要:
A rigid dip tube connector for a trigger spray bottle having a threaded opening. A cap body is screwed onto the opening and has a hinged cap attached thereto. The cap body has an annulus and an opening in the center for supporting a rigid dip tube. A plastic connector is provided and has a cylindrical bore extending from its bottom which fits into the opening in the cap body. The plastic connector is cylindrical and has an annulus in its upper portion for receiving a flexible tube for connection to a sprayer. The plastic connector fits into the annulus of the cap body so that the rigid dip tube and flexible tube align with one another. In a second embodiment, the annulus of the cap body is open and the rigid dip tube connects directly to the plastic connector or plunger. As a result, the plastic connector by itself connects and aligns the rigid dip tube and the flexible tube. The plastic connector snap fits into the opening of the cap body.

摘要:
The preferred embodiment of the invention comprises a glass sealed thyristor and a method for simultaneously constructing a plurality of thyristors and a common semiconductor wafer. The thyristor utilizes a body of semiconductor material with the cathode and base regions extending to one major surface and the anode region extending to the second major surface. A groove is etched in the first surface of the body of semiconductor material to expose the PN junction formed at the interface of the cathode emitter and cathode emitter base regions. A second groove is etched in the second major surface to expose the PN junction formed at the interface of the anode emitter region and the anode emitter base region. Ring shaped glass members are fused to the body of semiconductor material to form seals providing environmental protection for the PN junctions exposed by etching the grooves in the major surfaces of the body of semiconductor material. A plurality of thyristors can be simultaneously constructed on a common semiconductor wafer.

A two piece, molded plastic dispenser, that functions with a push-pull motion, comprising an outer shell and an inner shell. The outer shell comprises a top wall with an aperture defined at its center, and a skirt of generally cylindrical shape. A plug seal extends below the top wall, and annular groove and bead are formed in the vicinity of the upper end of the inner surface of the skirt and the underside of the top wall. The inner shell comprises a top wall, a tapered spud extending upwardly from the top wall, an annular barrier encircling the spud, and a depending skirt. Detents and arcuate wall segments extend, in interspersed fashion, about the perimeter of the upper shell, and cooperate with the bead on the outer shell. Vertical ribs on the inner surface of the outer shell cooperate with serrations on the exterior surface of the inner shell to guide the relative movement of the outer shell, in a vertical direction, while preventing relative rotation between the shells. The contents of the container are discharged through apertures in the inner shell proximate to the spud to flow through the aperture in the outer shell. The plug seal and annular barrier, and the spud and aperture, are fully engaged, when the dispenser is closed, to provide leak-proof operation. The arcuate walls segments extend vertically above the detents to protect same, and the underside of the annular bead abuts a shoulder on each wall segment when the dispenser is closed.
