A rim seal for use with containers for paint having an upstanding rim at one end and a groove located radially inwardly of the rim defined in part by an inner terminal edge. The rim seal includes an annular top section disposed generally transverely to the axis of a container and providing a planar support surface when assembled to a container. An inner wall section extends downwardly at an angle from the inner peripheral edge of the top section terminating in a radially inwardly directed rib adapted to overlie and seal with the edge of the container. Also, an angular outer section depending from the outer peripheral edge of the top section includes a radial section defining a ledge, and a lower terminal axially extending wall terminating and having an inwardly directed radial circumferentially extending rib. Application of an axial force on the top section produces outward flexing of the inner and outer sections whereby the rim seal can be applied to a container by automatic assembly means.

A disposable device for use as a litter box comprising a blank made of disposable flat material scored and cut in a predetermined pattern to form a receptacle section. The receptacle section has a generally rectangular base and upstanding opposing side walls and end walls and a top closure section including at least two opposing end panels pivotally connected to opposing end walls of the base. The receptacle section is actuatable between a closed position overlying the base, and an open position wherein the side and end panels are upright permitting access to the receptacle section. The corners at the juncture of the side and end panels form foldable portions which are collapsible to pivot inwardly and thereby maintain and lock the side and end panels in an upright, open position.

A disposable dental drill assembly is disclosed in this application and includes a housing in which is rotatably carried a rotor member including a turbine blade configuration and which is fixed to the end of a dental burr. The housing is formed with interlock means cooperating with complimentary means formed on a handle member whereby the drill assembly is easily removable from the handle member and can be replaced when the burr wears out. Both the housing and handle are formed with air passages and the handle is connected to a source of air pressure so that air flows over the turbine blades driving the rotor member and, accordingly, the burr. Because the drill assembly is disposable, the housing and the rotor member, including the turbine blade configuration, are made of a relatively inexpensive plastic material which can also be utilized for the handle member.

A sight for mounting on a golf tee having a target arm to be pointed at the target by the golfer when he places the tee on the ground together with a club face alignment arm fixed to the target arm and extending outwardly on opposite sides thereof and spaced forward of the ball when the ball is on the tee whereby to be clearly seen by the golfer so that the golfer then can position the club to set up the club face parallel to the alignment arm and thereby to be set up normal to the intended flight path of the ball.
