[0018] In order to make the technical scheme of the utility model more clear, the following combines the drawings of the utility model Figures 1 to 3 , and the utility model is explained in detail, it should be understood that the specific embodiment described in the specification is only for explaining the utility model, and is not for limiting the protection scope of the utility model.

[0019] The utility model is a special-shaped container, including container main part 1 and container bottom 2, the cross section of container main part 1 and container bottom 2 is square and four corners are all circular segments, container bottom 2 is close cooperation and is set in the lower end of container main part 1.

[0020] Specifically, the container body 1 is sequentially provided with a body portion 11 and a bottom portion 12 from top to bottom, wherein the outer diameter of the bottom portion 12 is not greater than that of the body portion 11, so that there is a step between the body portion 11 and the bottom portion 12; after the container bottom 2 is assembled to the bottom portion of the container body 1, the inner side wall of the container bottom 2 is tightly fitted and fixed with the bottom portion 12, the top end of the container bottom 2 is limited by the step, and the outer side wall of the container bottom 2 is smoothly butted with the outer side wall of the body portion 11.

[0021] Specifically, the four corners of the bottom portion 12 are first circular arc segments 121, and the four corners of the container bottom 2 are second circular arc segments.

[0022] Specifically, a groove 124 is arranged at the joint between the upper end of the bottom portion 12 and the body portion 11.

[0023] In the first embodiment, the cross section of the container body 1 and the container bottom 2 is square or rectangular, and the four corners are circular arc segments.

[0024] In this embodiment, it is found through testing that when the container bottom 2 is press-fitted to the lower end of the container body 1, the tight fit will cause the four sides of the container bottom 2 to be outwardly expanded, and the second circular arc segment will be inwardly contracted under stress, so that the second circular arc segment will more forcefully scrape the coating on the first circular arc segment 121 and cause it to form a shell, thereby affecting the coating on the body portion 11 to fall off; by arranging the groove 124 on the first circular arc segment 121, the second circular arc segment will not extrude and scrape the coating in the groove 124, which is equivalent to setting a protective zone to avoid affecting the coating on the body portion 11, and can prevent the problem of the coating on the body portion 11 from being affected and falling off.

[0025] In the second embodiment, the cross section of the container body 1 and the container bottom 2 is rectangular, and the four corners are circular arc segments; wherein the straight line segment with a short length of the four sides of the bottom portion 12 is a first short side 122, and the straight line segment with a long length of the four sides is a first long side 123; correspondingly, the straight line segment with a short length of the four sides of the container bottom 2 is a second short side, and the straight line segment with a long length of the four sides is a second long side.

[0026] In this embodiment, in addition to the arrangement of the first embodiment, as a preferred option, the groove 124 can be continuously arranged on the first circular arc segment 121 and the first short side 122; since the length of the first short side 122 is relatively short, when press-fitted, the second short side will not be expanded enough to the downside, and the second short side will also scrape the coating on the first short side 122, causing the coating to be peeled off; therefore, the groove 124 is also arranged on the first short side 122, which can further avoid the problem of coating peeling caused by press-fitting.

[0027] In the third embodiment, in order to further ensure that the coating of the body 11 is not affected, the groove 124 can be a ring groove surrounding the bottom 12. Since in the actual production process, if the thickness of the coating sprayed is too thick or the inner diameter of the container bottom 2 is too small (i.e. the problem of matching tolerance), the second long side can also scrape the coating on the first long side 123, and in this embodiment, the groove 124 is arranged in a ring, which can completely avoid the problem of the coating on the body 11 falling off due to the scraping of the coating on the bottom 12 by the side wall of the container bottom 2.

[0028] For the above three embodiments, the depth of the groove 124 cannot be too shallow, too deep, too wide or too narrow; if the coating is not stable, the coating will be too thick and cover the groove 124 if it is too shallow; it is not easy to process if it is too deep, and it is easy to break when processing the groove; if it is too wide, the top end of the container bottom 2 will not be supported and will be inwardly retracted, resulting in a step between the body 11; if it is too narrow, the groove 124 will be easily covered by the coating; after measurement and test, the depth of the groove 124 is 0.2mm-0.3mm, and the width is 0.8mm-1.5mm, which is more appropriate; and preferably the depth is 0.3mm and the width is 1mm, which is a moderate groove depth and is easy to process.
