In order that those skilled in the art can further understand the present invention, a description will be described in the following in details. However, these descriptions and the appended drawings are only used to cause those skilled in the art to understand the objects, features, and characteristics of the present invention, but not to be used to confine the scope and spirit of the present invention defined in the appended claims.
Referring to
A container 1 is included. Each of at least two lateral walls has a buckling recess 11 which do not penetrate through a wall of the container 1.
A cover 2 is as illustrated in
An inner diameter of the buckling recess 11 is smaller than the sum of one diameter of the buckle 21 and the buckling blocks 22 at two sides of the buckle 21.
The cover 2 is installed with a handle 23 which is integral or separably formed with the cover 2. In this drawing, it is illustrated that the handle 23 and the cover 2 are integral formed. If the handle 23 and the cover 2 are separated, the cover 2 has at least two buckling holes 24 for receiving two ends of the handle 23.
Referring to
By above mentioned structure, when the cover 2 covers upon the container 1, the buckling plates 20 of the cover 2 will be expanded so that the cover 2 covers the container 1. The buckles 21 of the buckling plates 20 of the cover 2 will align to and enter into the buckling recesses 11 of the container 1 so that the buckles 21 move downwards through a length. Thus the buckling blocks 22 of the buckles 21 will engage in the buckling recesses 11 of the container 1 (referring to
The present invention is thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
