Description

Technical Field

[0001] The utility model relates to the technical field of paper boxes, in particular to a foldable and open paper box. Background Art

[0002] Carton is a common packaging container, usually made of cardboard or paper. Cartons are widely used in packaging in various fields. They can provide good protection and display functions, protect products from damage, and convey brand information and product information to consumers. Cartons can be customized according to customer needs. This customization can meet the special needs of different industries and products, and improve the attractiveness and market competitiveness of carton packaging.

[0003] However, existing paper boxes usually consist of two parts: a main body and a cover. The main body is the bottom part of the paper box, which is usually used to contain products or items, and the cover is the top part of the paper box, which is used to cover and close the main body. Generally, the main body and cover of the paper box are usually designed to be split or semi-split. When storing or taking objects, the cover needs to be removed. After the cover is separated from the main body, it will occupy additional storage space and will also affect the aesthetics of the paper box. Utility Model Content

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] See also Figure 1-Figure 4 The utility model provides a technical solution: a foldable open paper box, comprising a first shell 1, one side of the first shell 1 is connected to a second shell 2, a paper storage tray 3 is arranged inside the first shell 1 and the second shell 2, and a locking component is arranged inside the second shell 2, and the locking component is used to lock the first shell 1 and the second shell 2 to each other.

[0035] It is worth mentioning that the paper box can be opened by folding the first shell 1 and the second shell 2, so that the items stored in the storage paper tray 3 are exposed, and the paper box can be closed by folding the first shell 1 and the second shell 2 in the opposite direction, so that the items stored in the storage paper tray 3 are hidden inside the paper box, thereby improving the convenience of opening and closing the paper box, and the first shell 1 and the second shell 2 can be locked to each other by the locking component to ensure that the first shell 1 and the second shell 2 maintain different states, preventing the first shell 1 and the second shell 2 from rotating at will when the paper box is opened or closed.

[0036] See also Figure 1-Figure 7 The first shell 1 and the second shell 2 are both trapezoidal structures when viewed from the side, the height and length of the first shell 1 and the second shell 2 are equal, the inclination angles of the inclined surfaces of the first shell 1 and the second shell 2 are equal, the height of the paper storage tray 3 is less than the height of the first shell 1 and the second shell 2, and the connection method between the paper storage tray 3 and the first shell 1 and the second shell 2 is a movable connection.

[0037] It should be noted that: since the first shell 1 and the second shell 2 are both trapezoidal structures when viewed from the side, and their heights, lengths and inclination angles of the inclined surfaces are equal, when the first shell 1 and the second shell 2 are folded to adjust their positions, the paper box can be opened or closed, and the connecting surfaces of the first shell 1 and the second shell 2 are ensured to fit each other, and the paper storage tray 3 can move inside the first shell 1 and the second shell 2, so that the paper storage tray 3 is exposed or hidden.

[0038] See also Figure 1-Figure 6The locking assembly includes a card block 4, a shift block 6 and a spring 7. One side of the card block 4 is fixedly connected to the spring 7, and the other end of the spring 7 is fixedly connected to the second shell 2. The card block 4 forms a telescopic structure inside the second shell 2 through the spring 7. The outer surface of the card block 4 is sleeved with a limit block 5, and the limit block 5 and the shift block 6 are connected to each other. A notch 8 is provided on the outer surface of the second shell 2, and the depth of the notch 8 is less than the length of the shift block 6. A card slot 11 is provided on one side of the first shell 1. The connection between the card block 4 and the card slot 11 is a snap-fit ​​connection. The card block 4 is symmetrically distributed about the longitudinal center line of the second shell 2.

[0039] The principle of being able to lock the first shell 1 and the second shell 2 with each other when the paper box is in the open state is: when the first shell 1 and the second shell 2 are folded to open the paper box and the paper storage tray 3 is exposed, the spring 7 pushes the card block 4 to slide out from the inside of the second shell 2 and engage with the card slot 11. Through the engagement connection between the card block 4 and the card slot 11, the first shell 1 and the second shell 2 can be locked with each other. To release the lock, the shift block 6 is pulled through the notch 8, so that the shift block 6 drives the card block 4 to slide into the inside of the second shell 2 through the limit block 5, and then the card block 4 and the card slot 11 are separated from each other, that is, the mutual locking between the first shell 1 and the second shell 2 is released.

[0040] See also Figure 1-Figure 6 A slide groove 9 is provided inside the second housing 2, the limit block 5 is connected to the clamping block 4 by rotation, a positioning groove 10 is provided on one side of the first housing 1, and the shifting block 6 is connected to the positioning groove 10 by snap-fit ​​connection;

[0041] The principle of being able to lock the first shell 1 and the second shell 2 with each other when the paper box is in a closed state is: when the first shell 1 and the second shell 2 are folded to close the paper box and the paper storage tray 3 is hidden inside the first shell 1 and the second shell 2, first pull the shift block 6 through the slot 8 so that the shift block 6 drives the limit block 5 to move to the position of the slide slot 9, then push the shift block 6 so that the limit block 5 and the card block 4 rotate, and then the shift block 6 passes through the slide slot 9 and is engaged with the positioning slot 10. Through the engagement connection between the shift block 6 and the positioning slot 10, the first shell 1 and the second shell 2 can be locked with each other.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
