Abstract: Disclosed is an apparatus for beading the edge or rim of a cup having a seamed annular sidewall and a polygonal base. A spinning head having a plurality of radially moveable forming members for contact with the rim to produce a bead is located over and in register with a cup-supporting base plate. The base plate together with relatively moveable socket forming wall members provides a seat for the cup on a cam operated elevator device which moves the cup upwardly. The socket is complementary to the polygonal base to prevent rotation of the seated and supported cup relative to the socket. The socket walls retract into a common horizontal plane with the base plate to permit rotationally driven star wheels to guide and confine cups onto the base plate in register with the forming means and off of the base plate away from the forming means. An air stream is directed into the cup to produce a positive pressure which inhibits dust from entering the cup during the forming operation.

Abstract: A cylindrically shaped, open, rimmed topped carton suitable for containing ice cream or the like includes a polygonal shaped base and a pair of side wall sections formed integral with the base which are joined together along mutual edges to provide an essentially cylindrical exterior surface defining a rimmed circular opening in one end of the carton opposite the base. A plurality of Y-shaped pleats are provided in lower portions of the side walls at circumferentially spaced intervals corresponding to the juncture of the edges defining the polygonal base to provide a smooth transition of the side walls from an angular cross-section at the base to a rimmed circular cross-section at the open end of the carton. A rolled rim extends outwardly from the cylindrical side walls to assure tight frictional engagement with a removable lid while also facilitating lid removal.

Abstract: A two part paperboard container having adjustable vents is described and is intended for use with a sublimable composition. The container consists of an inner tubular member and an outer tubular sleeve member, both of a truncated, conical configuration. The inner tubular member, which is adapted to receive the sublimable composition, is disposed within the outer sleeve member. The outer surface of the inner member is in frictional engagement with the inner surface of the outer sleeve member which functions to seal the carton. The inner member may be rotated relative to the outer sleeve member to at least partially align apertures provided in the upper cover portions of the tubular members, thereby exposing the composition to the air enabling it to sublime. Continued relative rotation of the tubular members will reset the apertures in the upper cover portions in a nonaligned position, thereby resealing the container.

Abstract: The interior of the paperboard carton is subdivided into two equal volumes by means of an internal divider panel which is formed as an extension of one end of the blank which is used to form the carton. The carton has front and back walls, side walls, and top and bottom closure flaps foldably connected to the front, back and side walls. The carton is formed from a one piece blank having opposite ends thereof overlapping each other and glued together at the center of the back wall, the divider panel is formed as an extension of one of the overlapping ends of the blank and is set back on that end of the blank so that the divider panel has basal marginal legs between which there extends a glue tab which is glued to the other end of the blank to form part of the glue seam joining the ends of the blank together. A paperboard material savings is realized by setting the divider panel back to form the marginal legs.

Abstract: A container made from an integral blank in which a solid bottom wall is provided with hingedly connected side walls and ends walls which may be folded normal thereto. The end walls are provided with additional panels which may be placed in surface-to-surface relation with the interior of the side walls and secured thereto in any suitable manner as by any automatic machinery such as a "tray former". A pair of the securement panels from opposite end walls and opposite corners of the box have extensions which may be folded inwardly toward the opposite side wall panel to form a central partition. These extensions are longer than half the transverse distance between the opposite side walls so that portions of the extensions may meet in surface-to-surface relation to form a partition.

Abstract: The improved shock-absorbing wheel suspension assembly of the present invention comprises a rigid yoke having a generally upstanding neck and a pair of downwardly diverging hollow tubular sleeves connected to the lower end of the neck, both sleeves being directed either rearwardly or forwardly relative to the neck. A pair of flexible resilient lever support arms are provided which have their upper ends extending into the sleeves. Their middle portions are generally parallel to each other and extend downwardly and in the same rearward or forward direction as the sleeves. The lower ends of the arms are angled to approximate each other in an about horizontal plane and are secured in the central hub of a wheel disposed therebetween. Thus, the wheel is disposed rearwardly or forwardly of the yoke and is adapted for rotation on an axle formed by the lower ends of the arms. The neck is connected to an upwardly extending stem, in turn connectable to the underside of the body of a vehicle or the like.

Abstract: A lid insert is provided for releasable connection to a plastic lid having a subtantially flat top surface and an upwardly and inwardly projecting peripheral bead disposed above and spaced from the top surface of the lid. The lid insert is made of paperboard material having a planar configuration generally corresponding to the configuration of the flat top surface of the lid. The periphery of the planar lid insert includes a plurality of alternating indents and nodes. The area defined by the outermost points of the insert is greater than the area defined by the upwardly and inwardly projecting bead. This peripheral configuration of alternating nodes and indents facilitates the initial placement of the insert on the lid and enables the insert to compensate for the different expansion characteristics of the lid and the lid insert.
