Abstract: A method for blow molding bottles having a hole formed in a molded interior recess extending from a top face of a bottle neck includes the steps of: (i) providing a mold having a neck forming cavity with an end flange surface therein; (ii) disposing a parison of molten material within the mold; (iii) introducing pressurized fluid into the parison to expand it against the mold walls, thereby forming a final shape of the bottle; (iv) forming the interior recess in the bottle by advancing a recess forming rod through a hole in the end flange surface and into the neck forming cavity; and (v) creating a dispensing hole in the interior recess by advancing a punch through a hole in an end face of the recess forming rod.

Abstract: An apparatus for blow molding bottles having a hole formed in a molded interior recess is provided. The apparatus includes a mold having a neck forming cavity having an end flange surface. A recess forming rod is slideable within a hole in the end flange surface from an initial position wherein a face of the rod is withdrawn into the hole in the mold to an extended position wherein the face of the rod protrudes into the neck forming cavity so as to create the molded interior recess. A punch is slideable within a hole in the rod from an initial position wherein a face of the punch is withdrawn into the hole in the mold to an extended position wherein the face of the punch protrudes beyond the face of the rod into the neck forming cavity so as to create the hole in the interior recess.

Abstract: A mold having a hole therein is provided, with a punch disposed within the hole in the mold surface. A portion of the punch extends out beyond the mold surface in an initial position such that the wall of the structure is initially formed therearound. The punch is movable to an activated position wherein the punch extends out beyond the mold to an extent greater than in the initial position. The punch is moved from the initial position to the activated position at a time interval after blow molding selected so that at least a portion of, and preferably a majority by volume of, the material forming the wall of the structure is in a molten state such that the cutting edge of the punch forms a hole through the wall of the structure along a line substantially perpendicular to a direction of travel of the punch.

Abstract: A children's wagon comprising a wagon body, a bottom wall, and front and rear bolsters secured to the bottom wall. The front bolster is pivotally secured to the bottom wall and a pin is associated with the bottom wall and is adapted to extend downwardly therefrom to interfere with the front bolster movement to thereby minimize the possibility of tipping of the wagon. The pin is adapted to be moved upwardly out of interfering position whereby the front bolster can be moved 180° in either direction to thereby place the wagon in more convenient positions for transportation and storage. The front and rear bolsters are each provided with shock absorbers positioned above the front and rear axles adjacent each of the wagon wheels. Slotted vertically extending extensions on each side of each bolster receive the wagon axles and provide for vertical movement of the bolsters relative to the axles.
