Publication number: 20090097915Abstract: Disclosed is a protector for a retro-reflective road marker mounted on a road that includes a top surface that has a generally flat region and a bottom surface oppositely disposed from the top surface. The generally flat region has an opening where the retro-reflective road marker can be at least partially mounted to the protector by deforming studs located along the perimeter of the opening such that the retro-reflective road marker is moveable independent from the protector. The protector is made from a moldable polymer and the top surface is operable to protect the road reflector from motor vehicle tires passing thereover.Type: ApplicationFiled: October 14, 2008Publication date: April 16, 2009Applicant: Pac-Tec, Inc.Inventor: Peter Hedgewick

Patent number: 5098217Abstract: A pavement marker for a roadway surface includes a lower base portion and a retro-reflective lens mounted on the base portion at an angle to it. A photopolymerizable clear acrylic protective hard coat is deposited over and integrally formed with the front face of the lens for resisting abrasion of the lens and reducing the loss of optical efficiency resulting from such abrasion. The pavement marker also includes a frame of generally arcuate cross-section formed about an edge of the hard coat potentially susceptible to peeling from impact of vehicle tires against the hard coat. The frame is preferably formed as a bead raised from the face of the marker, and the bead includes a sharp interior edge lying generally perpendicular to the lens, adjacent the edge of the hard coat.Type: GrantFiled: May 23, 1990Date of Patent: March 24, 1992Assignee: Pac-Tec, Inc.Inventors: Peter Hedgewick, Douglas S. Forrer

Patent number: 5061114Abstract: A reflective pavement marker of the type having a shell-like housing of synthetic resin or other moldable material with a reflective end wall of light transmitting material with a filler of epoxy or other potting material. The reflective end wall is formed with retro-directive reflective elements of cube corner type. The end wall is dished so that light rays reflect from the array of cube corner reflective elements and converge to enhance the candle power of the reflective light. Also disclosed is a method and apparatus for making the device.Type: GrantFiled: February 5, 1990Date of Patent: October 29, 1991Assignee: Pac-Tec, Inc.Inventor: Peter Hedgewick

Patent number: 5002424Abstract: A reflective pavement marker of the type having a shell-like housing of synthetic resin or other moldable material with reflective end walls of light transmitting material and a filler of epoxy or other potting material. Ribbing is formed on the inner surface of the housing. The ribbing has a surface that makes an acute angle with respect to the inner surface of the housing to coact with the filler material to increase the resistance to separation of the filler material from the housing.Type: GrantFiled: January 24, 1990Date of Patent: March 26, 1991Assignee: Pac-Tec, Inc.Inventor: Peter Hedgewick

Patent number: 4883384Abstract: A roadway pavement marker protective member defined by a single rail for the protection of pavement markers. A pavement marker is placed on the roadway surface and one or two of these rails are placed about the pavement marker for its protection. The protective member deflects potential hazards presented by oncoming traffic, such as snowplow machines, from the pavement marker and prevents it from being dislodged.Type: GrantFiled: December 14, 1988Date of Patent: November 28, 1989Assignee: Pac-Tec, Inc.Inventor: Peter Hedgewick

Patent number: 4444327Abstract: A safety container and closure assembly including an integrally-molded, one-piece plastic cap having a sealing portion which provides an "oil-can" effect during axial and rotative motion of the cap relative to the container. The sealing portion comprises a relatively thin, radially outwardly curved wall which is integrally joined to a relatively stiff annular base portion from which a peripheral skirt portion axially projects for receiving the mouth of the container. Integrally formed with the sealing portion is a relatively thin, annular biasing portion which, in turn, is integrally formed with a relatively stiff, inner, disc-like base portion. The biasing portion biases the sealing portion to axially spaced positions such that when the cap is placed on the container, the biasing portion biases the cap in a fixed axial sealing position relative to the container and simultaneously applies pressure to the sealing portion.Type: GrantFiled: March 11, 1983Date of Patent: April 24, 1984Inventor: Peter Hedgewick

Patent number: 4319690Abstract: A safety closure and container assembly including a container and a closure comprising outer and inner caps which may be attached to the container by conventional capping machines. In first, second, third and fourth embodiments of the invention, the inner cap is formed with a circular dome-shaped top panel with a skirt portion projecting axially therefrom. The projecting skirt portion is threaded on its interior surface for engagement with a conventionally threaded container finish. A plurality of upwardly extending and spaced apart drive members are integrally molded with the periphery of the top panel. A plurality of ramped ratchet lugs also extend upwardly from the upper surface of the top panel. The outer cap has a circular end wall with an axially projecting second skirt portion.Type: GrantFiled: November 14, 1980Date of Patent: March 16, 1982Assignee: International Tools (1973) LimitedInventors: Stewart H. Birrell, Peter Hedgewick

Patent number: 4159779Abstract: A safety closure and container assembly including a container, cap and combined spring and sealing member. Retention nibs are 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 nibs 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.Type: GrantFiled: August 7, 1978Date of Patent: July 3, 1979Assignee: International Tools (1973) LimitedInventor: Peter Hedgewick
