Abstract

(57) [Summary] [Problem] To provide a trash can structure having a structure for effectively compressing trash volume in a trash can. An inner cylinder (20) and an isolation cylinder (30) are provided in an outer cylinder (10), and a tread plate (50) for compressing dust by stepping on a leg is provided on an upper portion thereof. The opening space around the opening is divided into a front groove and a rear groove, and a first elastic portion made of a spring or the like is provided at an appropriate position in each of the installation spaces. By providing a second elastic portion and suspending the tread plate 50 from these elastic portions via a pulley, when the tread plate is stepped on by a leg, the tread plate descends while compressing dust from a position where the opening is closed, When the step on the tread plate 50 is stopped by the leg, the tread plate 50 automatically returns to the original position and closes the opening.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a trash can structure, and more particularly to a trash can having a structure for compressing the volume of trash.

[0002]

[Prior art]

 As is well known in the general use of trash cans, a garbage bag is first placed on the inside of a trash can, and trash is thrown into the trash bag. Regarding garbage and its collection, in many areas, a method is adopted in which designated garbage bags are purchased and only the garbage in the designated garbage bags is collected.

[0003]

[Problems to be solved by the invention]

 The more garbage, the more garbage bags will be used, but the purchaser of the designated garbage bags will increase the cost of garbage bags, so we hope that the garbage bags will be saved as much as possible. . Therefore, the structure of the trash can of the present invention is provided to effectively reduce the volume of the trash.

[0004]

[Means for Solving the Problems]

 An inner cylinder and an isolation cylinder are provided in the outer cylinder, and a tread and a top cover are provided on the upper part of the outer cylinder, where the dust is compressed with the legs. In particular, the top cover is a surface plate with an opening inside. The installation space inside the surface plate is divided into a front groove and a rear groove, and when the tread is stepped on with the legs, the tread descends, compresses dust, and is located at an appropriate position in the installation space. A pulley is pivoted, and a restoring structure including a first elastic portion provided in the front groove, a second elastic portion provided in the rear groove and the like is provided, and both ends of the first and second elastic portions are respectively provided. The strap is fixed on the tread and the pulley so that when the tread is stopped, the position of the tread is automatically restored.
