Abstract: An improved structure of trashcan includes an outer can with a controllable upper cover. The upper cover has a connecting hole with a stepping part that moves downward in the outer can when being stepped. A base is at the bottom of the upper cover. First, second, third, and fourth tracks surround the stepping part at symmetrical positions of the base. Each track accommodates a restoring assembly that connects to the stepping part so that the stepping part can restore its original position after the stepping part moves to the bottom of the trashcan. The first track and the second track are stacked vertically. The third track and the fourth track are also stacked vertically. This configuration decreases the area occupied by the base. As a result, the stepping area of the stepping part is increased for the user's convenience to step on.

Abstract: A materials handling apparatus for aiding in loading and transporting various materials has three major components, a wheeled cart, a truncated conical cylinder which is carried by the cart and a compaction lid which provide the apparatus with the capability of being operated in three different modes. In the first mode, a conventional trash bag is placed inside the cylinder and the lid can be placed atop the cylinder. In this mode, the apparatus operates as a conventional trash can. In a second mode, the cylinder in placed within a trash bag to protect it from being damaged by materials such as tree and shrub clippings or other materials which could tear the bag. In the third mode no trash bag is used, the materials are loaded into the cylinder, and when loading is complete, the cylinder is lifted off of the materials for direct deposit into a disposal site.

Abstract: A greeting card display has frame-supported rails and card shelves with laterally adjustable dividers which form multiple adjustable card pockets for display and storage of greeting cards and envelopes. The number of card shelves and pockets can be easily set-up and altered by any desired arrangement of the card shelves and dividers. The card shelves can be use in combination with other types of product displays on the same supporting frame.

Abstract: A garbage can capable of compressing garbage volume consists of an outer cylinder and a top cylinder. A top cover has a top plate with a through hole. The circumference of the top plate extends downwards to form an inner wall and the outer circumference of the top plate extends downwards to form an outer wall such that a space between the outer and inner walls can be formed. The front and the back sides of the space form a front trough and a back trough respectively and a small sheaf is placed on the front and back sections of the left and right hand walls of the space with a pedal located below the upper cover. A reset component includes mainly a first elastic part and a second elastic part. The first elastic part is located inside the front trough of the top cover, and the two ends have been fixed on a wire pedal. The second elastic part is placed inside the back trough of the top cover, and the two ends are fixed respectively on pedal with the wire.

Abstract: An apparatus for heat sealing composite lids, made of a laminate of a light ductile alloy coated with a layer of thermoweldable plastic material, on glass containers. The apparatus applies, under pressure, a flexible membrane onto said lid while disposed in position on the mouth of a glass container. The membrane is a simple sheet stretchingly supported by its outer periphery on a movably and hingedly supporting frame. The side of said membrane opposite said lid is subjected to a controlled heat flow, thus sealing the lid to the container.
