Abstract: A dog waste receptacle device has a container with an opening at the top and bottom, a top cover and a bottom tray that each can be opened and closed freely, a latch for holding the bottom tray in a closed state, and a carrying rod whose lower end is attached to the side of the container. The top cover is hinged to the carrying rod in such a manner that it can be opened and closed freely. A trigger connected to the top cover for opening and closing it is mounted on the upper part of the carrying rod. A latching device capable of latching and unlatching the trigger is provided to hold the trigger in its position with the top cover open. A paper bag to accommodate dog droppings is placed inside the container. The top cover is closed under its own weight by releasing the trigger and the device is carried along by holding the carrying rod. As soon as the dog shows a motion of excreting, the top cover is opened and the container is placed under the dog's bottom.

Abstract: A method of molding a heat-resistant container comprising a primary blow molding step, a primary heat treatment step, a secondary heat treatment step, and a secondary blow molding step. In the primary blow molding step a synthetic resin preform is blow-molded into a primary blow-molded article. In the primary heat treatment step, the primary blow-molded article is held in a heat treatment mold and subjected to heat treatment. The primary blow-molded article, removed from the mold, shrinks, and forms an intermediate molded article. In the secondary heat treatment step, the intermediate molded article is subjected to heat treatment outside the mold. At this time, almost no shrinkage occurs. In the secondary blow molding step, the intermediate molded article is blow molded within a final blow mold to form a final molded product.
