Storage box structure

Abstract

This invention relates to a storage box structure, which mainly features positioning ribs and positioning grooves formed on the outer and inner walls of opposite sides of the box body. The positioning ribs and positioning grooves on opposite sides of the box body are staggered, thereby allowing two storage boxes to be placed in the same or opposite directions during use, so that the upper and lower storage boxes can be mutually accommodated or stacked. In addition, the storage box of this invention is made of stainless steel and other metal materials, thus avoiding the release of harmful substances such as plasticizers. Therefore, when using the storage box of this invention to store food or other food items, the hygiene and safety of the food can be ensured.

Claims

1. A storage box structure made of metal, comprising a box body with a receiving space provided in the box body, the inner and outer sides of the receiving space forming the inner wall and outer wall of the box body respectively, the upper end of the box body forming the opening of the receiving space, and the box body forming a first side and a second side, the box body having two first positioning ribs formed on the outer wall of the first side, and two first positioning grooves formed on the inner wall of the first side at positions corresponding to the two first positioning ribs, and two second positioning ribs formed on the outer wall of the second side, and two first positioning grooves formed on the inner wall of the second side. Two second positioning grooves are formed on the inner wall of the side opposite to the two second positioning ribs. The two first positioning ribs and two first positioning grooves on the first side of the box body are staggered with the two second positioning ribs and two second positioning grooves on the second side of the box body. The box body has two spaced first abutment parts formed on the inner wall of the first side. The two first abutment parts are respectively located on the side of the two first positioning grooves. The inner wall of the second side of the box body has a second abutment part at the position between the two second positioning grooves. The upper ends of the first abutment part and the second abutment part are adjacent to the opening of the accommodating space.

2. The storage box structure as described in claim 1, wherein, The first positioning rib, the first positioning groove, the second positioning rib, and the second positioning groove of the housing extend from top to bottom and gradually narrow into a cone shape.
