Abstract: A safety closure and container assembly including a container, cap and combined spring and sealing member. A retention rib is formed on the inner surface of the skirt of the cap, and a spring and sealing member has a radially projecting flange that engages the retention rib to prevent separation of the spring and sealing member from the cap. Cap and container locking elements are formed respectively on the inner surface of the skirt of the cap and the outer surface of the mouth of the container. The cap and container locking elements are engageable with and disengageable from each other by combined axial and rotary motion of the cap relative to the container. The spring and sealing member biases the cap and container locking elements toward locked engagement with each other when the cap is applied to the container.

Abstract: A child resistant safety closure and container assembly of the type including a cap having locking lugs projecting from its skirt for engagement with complementary bayonet locking elements on the container. A combined spring and sealing member is carried by the cap to resiliently maintain the cap and container in locked engagement, and provide a moisture proof seal. The spring and sealing member includes a plunger having a cylindrical base portion concentric with a cylindrical sealing wall. A plurality of radial stiffening members extend between the base portion and the inner end of the cylindrical sealing wall. In one embodiment, the stiffening members are in the form of ribs molded integrally to the side wall. In another embodiment, the stiffening members are in the form of flutes molded into the side wall.

Abstract: A pavement marker of the type including a shell-like body of light transmitting material, such as synthetic resin, having a reflective wall formed thereon, and which is filled with epoxy resin or the like for reinforcing the shell-like body against external forces applied by vehicles. The body has a fore and aft axis that intersects the reflective wall and extends parallel to the direction of travel of vehicles when the base of the pavement marker is secured to a roadway. The reflective wall has a lower edge adjacent the plane of the base that is spaced forwardly of the upper edge thereof such that the reflective wall is in nonperpendicular relationship with the plane of the base, and the outer surface of the reflective wall is curved outwardly and downwardly between the upper and lower edges. The reflective wall also curves rearwardly from the fore and aft axis on opposite sides thereof. The body also has a top surface that is convexly curved.

Abstract: A pavement marker having a shell-like body with a chamber formed therein, the body being at least partially of transparent material to form a transparent outer wall for the chamber so that the interior of the chamber is visible through the transparent outer wall. Marker elements are located in the chamber so as to be visible through the transparent wall of the chamber. The body has a continuous, or endless, peripheral edge portion that lies in a base plane. The body projects from the base plane and is of dome-like configuration to define the chamber. A closure plate is secured to the body at the peripheral edge portion thereof to close the chamber. The closure plate, either before or upon installation on the surface of a roadway, is sealed to the body to hermetically seal the chamber. Either daytime or nighttime marker elements, or both, may be provided in the chamber so as to be visible through the transparent wall thereof.

Abstract: A foldable triangular traffic signalling device including a collapsible body having first, second and third leg members connected together for movement between an erect triangle forming position in which each leg member constitutes one leg of a triangle and a folded position. One of the leg members has a pair of spaced sidewall members, and the other leg members each have an inner end received in the space between the sidewall members and pivotally connected to the sidewall member such that the other leg members can be folded and stored within the space between the sidewall members when the device is not in use. Light reflective means is provided on the outer surface of the leg members to define a triangular warning device when the leg members are in their erect position.
