Abstract
Description
Technical Field
[0001] This utility model relates to the field of corrugated paper packaging box technology, specifically a corrugated paper packaging box that is easy to divide. Background Technology
[0002] Corrugated cardboard boxes are detachable cardboard boxes made of corrugated cardboard. Corrugated cardboard is made by bonding together face paper, liner paper, core paper, and corrugated paper that has been processed into a wave shape. Depending on the needs of product packaging, corrugated cardboard can be processed into single-face corrugated cardboard, three-layer corrugated cardboard, five-layer, seven-layer, eleven-layer, etc. Single-face corrugated cardboard is generally used as a protective lining for product packaging or to make lightweight card slots or pads to protect products from vibration or impact during storage and transportation. Most existing corrugated cardboard boxes have a relatively simple structure, making it inconvenient to divide the internal storage space.
[0003] To address the aforementioned issues, we propose a corrugated cardboard packaging box that facilitates separation. Utility Model Content
[0004] To address the problems in the background art, this utility model provides a corrugated cardboard packaging box that is easy to separate.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A corrugated cardboard packaging box that is easy to separate includes a box body, a supporting base plate is provided on the bottom inner side of the box body, and an inner lining is provided on all four sides of the upper end of the supporting base plate. The inner lining is in close contact with the inner wall of the box body. Multiple sets of dividing grooves are provided in the middle of the upper end of the inner lining, and the multiple sets of dividing grooves are distributed at equal intervals.
[0007] Preferably, the bottom of the liner is provided with two sets of pins on both sides, and the upper end of the support base plate is provided with insertion holes around the perimeter, and the pins are inserted into the insertion holes.
[0008] Preferably, the upper perimeter of the box is provided with two sets of horizontal cover plates and vertical cover plates respectively.
[0009] Preferably, the back of the liner is provided with double-sided adhesive, which allows the liner to be tightly connected to the inner wall of the box.
[0010] Preferably, the liner is made of a single piece of cardboard folded in half.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] In this solution, an inner liner is installed around the inner cavity of the box, and multiple sets of partition grooves are opened in the upper center of the inner liner. During use, the user can insert a partition plate into the corresponding partition groove as needed, thereby dividing the inner cavity space of the box and preventing items from contacting or colliding with each other.

[0018] The technical solution in this application embodiment is to solve the problems of the background technology mentioned above. The general idea is as follows: By installing an inner liner 6 around the inner cavity of the box body 1, and opening multiple sets of partition grooves 8 at the upper center of the inner liner 6, the user can insert a partition plate into the partition groove 8 as needed during use, thereby providing convenience for the user to divide the inner cavity space of the box body 1.
[0019] Example: Refer to Figure 1 - Figure 4 As shown, this embodiment of a corrugated cardboard packaging box that is easy to separate includes a box body 1. A supporting base plate 4 is provided on the bottom inner side of the box body 1. An inner liner 6 is provided on all four sides of the upper end of the supporting base plate 4. The inner liner 6 is tightly attached to the inner wall of the box body 1. Multiple sets of dividing grooves 8 are provided in the middle of the upper end of the inner liner 6. The multiple sets of dividing grooves 8 are evenly distributed. By inserting dividing plates into the dividing grooves 8, the inner cavity space of the box body 1 can be divided for use. The design of multiple sets of dividing grooves 8 can improve the convenience of separation.
[0020] In some examples, the bottom of the liner 6 is provided with two sets of pins 7 on both sides, and the upper end of the support base plate 4 is provided with holes 5 around the perimeter. The pins 7 are inserted into the holes 5 to limit the installation of the liner 6 and improve the stability of the liner 6 installed on the inner wall of the box body 1.
[0021] In some examples, two sets of horizontal cover plates 2 and vertical cover plates 3 are respectively provided around the upper part of the box body 1. By folding the two sets of horizontal cover plates 2 and vertical cover plates 3, the top opening of the box body 1 can be covered and sealed.
[0022] In some examples, double-sided adhesive tape 9 is provided on the back of the liner 6, which allows the liner 6 to be tightly connected to the inner wall of the box 1, further improving the stability of the liner 6 installation and preventing the liner 6 from falling off the support base plate 4.
[0023] In some examples, the inner liner 6 is made by folding a single piece of cardboard. This one-piece design improves the ease of cutting and processing the inner liner 6.
[0024] In some examples, the materials used in this invention are all made of corrugated paper.
[0025] The working principle of this utility model is as follows:
[0026] During use, first place the support base plate 4 into the bottom of the inner cavity of the box 1, and then install the inner liner 6 around the upper end of the support base plate 4 in sequence. During the installation process, the pins 7 on both sides of the bottom end of the inner liner 6 need to be inserted into the pin holes 5 at the upper edge of the support base plate 4 to limit the installation of the inner liner 6 and improve the stability of the inner liner 6.
[0027] By opening multiple sets of partition grooves 8 in the upper middle part of the inner lining 6, users can insert partition plates into the partition grooves 8 as needed during use, thereby dividing the inner cavity space of the box 1 and preventing items from contacting or colliding with each other.
[0028] This utility model provides convenience for users to divide the internal space of the box body 1 by attaching an inner liner 6 to all four sides of the inner cavity of the box body 1, and opening multiple sets of partition grooves 8 in the upper middle part of the inner liner 6.
[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
