However, the present invention may be implemented in various other forms and is not limited to the embodiments described herein. In order to clearly explain the present invention in the drawings, parts not related to the description are omitted, and identical or similar components are assigned the same reference numerals throughout the specification.

In the description of the embodiment of the present invention, based on FIG. 1, the packaging box is referred to as the upper side or upper side wall of the upper portion (y direction in FIG. 1) and the lower side or upper side wall of the lower portion (-y direction of FIG. 1). It will be explained using the same meaning as the lower side part. In addition, in the description of the embodiment of the present invention, based on FIG. 1, the packaging box is referred to as the left side or left side wall of the left portion (-x direction in FIG. 1), and the wall of the right portion (x direction of FIG. 1) is referred to as the right side. Alternatively, it will be explained by expressing it in the same sense as the right side part.

Figure 1 is a diagram for explaining a first embodiment of the present invention, and shows a packaging box.

The packaging box of the first embodiment of the present invention includes a tray 100 and a box 300.

The tray 100 is fixed by inserting a product (P) such as a bottle containing cooking oil. This tray 100 can accommodate multiple products P while stored in the tray 300 .

The tray 100 includes a main body 110, a storage groove 130, and a movement prevention portion 150 (see FIG. 2).

The main body 110 is the middle part of the tray 100.

The storage groove 130 is shaped like a groove in which a portion of the main body 110 is dug so that the product P can be inserted. Taking a bottle containing cooking oil as an example, the storage groove 130 can firmly fit the bottle cap, bottle neck, and part of the bottle body (see FIGS. 2 and 3).

The movement prevention part 150 extends from the main body 110 and may be fixed to the bin 300. The movement prevention part 150 includes an upper movement prevention part 151 extending to the upper side of the main body 110 (y direction in FIG. 2), and an upper movement prevention part 151 extending to the left side of the main body 110 (-x direction in FIG. 2). It includes a left movement prevention part 153, and a right movement prevention part 155 extending to the right (x direction in FIG. 2) of the main body 110. In the description of the first embodiment of the present invention, the upper movement prevention part 151, the left movement prevention part 153, and the right movement prevention part 155 of the tray 100 are made of the same or similar structure, so the upper movement prevention part 155 has the same or similar structure. (151) will be described as an example, and the left movement prevention unit 153 and the right movement prevention unit 155 will be given the same symbols as the upper movement prevention unit 151 and will be replaced by their description.

Figure 4 is a cross-sectional view taken along section A-A of Figure 2, and the movement prevention part 150 includes an extension part 157, a fixing groove part 159, and a fixing protrusion part 161.

The extension portion 157 extends from the main body 110 of the tray 100 in the left, right, and upper directions. And a fixing groove 159 and a fixing protrusion 161 are formed in the extension part 157. The fixing groove 159 is a part where the tray fixing part 301 (see FIG. 6) of the paper box 300 is inserted and the tray 100 is fixed to the paper box 300, and has a shape dug in the -z direction (based on FIG. 4). achieves The bottom portion of the fixing groove portion 159 maintains a constant height (h) from the bottom portion of the extension portion 157. In this way, the height of the bottom surface of the fixing groove 159 is higher than the height of the bottom surface of the extension part 157 because the tray fixing part 301 of the box 300 is inserted into the fixing groove 159 due to an elastic force. Through this action, the force with which the tray fixing part 301 presses the fixing groove part 159 can be maximized. This structure maintains the tray 100 being firmly fixed to the tray 300, preventing products (P) with a large load, such as bottles of cooking oil, from flowing together with the tray 100, thereby stably housing the product. .

The fixing protrusion 161 is disposed above the bottom surface of the fixing groove 159 and at the same time is disposed outside the fixing groove 159. The fixing protrusion 161 is caught by the tray fixing part 301 and serves to prevent the tray 100 from moving. And the fixing protrusion 161 includes a first inclined portion 161a whose outer surface is inclined and a second inclined portion 161b whose inner surface is inclined. It is preferable that the inclination angle (a) of the first inclined portion (161a) of the fixed protrusion (161) is smaller than the inclination angle (b) of the second inclined portion (161b) relative to the horizontal plane (see FIG. 4 ). This structure allows the tray 100 to be easily inserted into the tray fixing part 301 of the box 300 through the low slope of the first inclined part 161a of the fixing protrusion 161 when the tray 100 is assembled to the box 300. After the fixing protrusion 161 is inserted into the tray fixing part 301, it is prevented from being separated from the tray fixing part 301 by the high slope of the second inclined part 161b of the fixing protrusion 161. . That is, the first inclined portion 161a and the second inclined portion 161b of the fixing protrusion 161 of the embodiment of the present invention are easily inserted into the paper box 300 and are easily separated from the paper box 300 after being inserted. The product packaging process can be easily performed by maintaining a solid fixed state without being damaged.

Meanwhile, the tray 100 of the first embodiment of the present invention is made of synthetic resin material (plastic material), and as shown in FIG. 1, its size is preferably small compared to the size of the product. The tray 100 is preferably, for example, approximately one third of the length of a bottle containing cooking oil.

The size of the tray 100 may vary depending on the size of the product cap (lid) and the neck of the bottle, and it is desirable to have a structure that can securely secure the cap and the neck of the bottle. The size of the tray 100 is preferably in the range of 32% to 36% compared to the length of the bottle containing cooking oil. In this first embodiment of the present invention, if the size of the tray 100 is less than 32% of the product, it is difficult to firmly fix it to the tray 300, and if the size exceeds 36%, the amount of plastic used cannot be sufficiently reduced. It may become impossible. That is, the first embodiment of the present invention can significantly reduce the size of the tray 100, thereby reducing the amount of plastic used, reducing environmental pollution, and protecting heavy products from external impacts.
