Abstract: A tube with indication function is provided, including a reflection layer and an organization layer. The reflection layer is located on the outermost layer of the tube. The reflection layer is transparent and includes a number of reflectors that are capable of reflecting light densely distributed therein. With the tube being set up in a dark environment and irradiated with light, the light may transmit through the transparent reflection layer to reach the reflectors distributed in the reflection layer such that the reflectors reflect the light back to project the light outward. The reflection of light makes the tube noticeable to achieve an effect of indication, allowing a user to visually identify the location of the tube.

Abstract: A tube packaging box is generally in the form of a box having an open top. The box includes a front board, a rear board, a bottom board, and two side boards such that the boards collectively form a rectangular receiving space. The front board is connected to a folding board. The folding board is extended to form a first folding section and a second folding section. With a tube positioned in the receiving space, the folding board is folded inwardly into the receiving space such that the first folding section of the folding board covers a top side of the tube and the second folding section is fit into and interposed between the tube and the rear board to have the second folding section simultaneously clamped by and between the tube and the rear board with two opposite edges of the first folding section abutting the tube.

Abstract: A guiding device for drawer is disclosed. The device comprises a cupboard body having a vertical slot at the inner wall thereof near to the external edge of the cupboard body, and a plurality of drawers. A plurality of safety connection blocks are mounted to the slot so that only a sliding space is provided. The top and bottom sides of each safety connection blocks are provided with rollers, so that when a drawer is withdrawn, the rail board located at the side of the drawer will squeeze in between two adjacent rollers and the sliding space of the slot is fully filled. This will cause the other safety connection blocks to mutually urge against each other and other drawers are restricted from withdrawal.
