Description

Technical Field

[0001] The present invention relates to the technology of fasteners, in particular to a fastener device and a packaging device including the fastener device. Background Art

[0002] Currently, the opening and closing of a packaging box are usually controlled by magnets or fasteners. When using magnets, they are usually embedded on the surface or inside of the box, and the box is closed by the mutual attraction of at least two magnets. However, the source and price of magnet materials are extremely unstable, resulting in the disadvantage of high price cost. Among the currently used fasteners, some are designed with complex structures for maintaining stability, while some are simple in design but lack stability. Complex-structured fasteners also incur higher manufacturing, storage, and transportation costs. In addition, most existing fasteners are metal parts, while packaging boxes are mostly made of paper materials, which is not conducive to unified recycling and treatment and is not environmentally friendly enough.

Detailed implementation manner

[0026] To describe the technical content, achieved purpose and effects of the present invention in detail, the following is described in conjunction with the implementation manner and accompanied by the drawings.

[0027] The most crucial concept of the present invention lies in: through the engagement design of the first inclined side and the second inclined side, the engagement between the buckle surface and the buckle bottom is made simpler, and thus the overall structure of the buckle device is more simplified and compact.

[0028] Please refer to Figures 1 to 3 , a buckle device S, including a buckle bottom 1 and a buckle surface 2, the buckle bottom 1 includes at least one first inclined side 11, the buckle surface 2 includes a first panel 21, a second panel 22 and at least one third panel 23, wherein the first panel 21 and the second panel 22 are rotatably connected, the third panel 23 is connected above the second panel 22, the third panel 23 includes at least one second inclined side 231, when the buckle device S is buckled, the first inclined side 11 and the second inclined side 231 are engaged.

[0029] The working principle of the present invention is briefly described as follows: when buckling the buckle device, the second panel is folded relative to the first panel, so that the buckle surface is generally located above the buckle bottom, and then the third panel is pressed downwards, the tension provided by the overall buckle device enables the second inclined side to be pressed below the first inclined side, and the first inclined side and the second inclined side are engaged through the cooperation of their respective inclined surfaces; when opening the buckle device, only need to gently lift the third panel, so that the second inclined side is away from the first inclined side until the engaged state of the two is disengaged.

[0030] It can be seen from the above description that the beneficial effects of the present invention are: (1) through the engagement design of the first inclined side and the second inclined side, replacing the complex engagement structure in the prior art, such as the pin hole and pin structure, the engagement between the buckle surface and the buckle bottom is made simpler, thus simplifying the specific engagement structure; (2) the buckle device of the present invention is mainly composed of a buckle surface and a buckle bottom with simple structures, the overall structure of the buckle device is simpler and more compact, thus simplifying the processing method and effectively saving costs.

[0031] Furthermore, when the locking device S is fastened, the locking bottom 1 is located below the second panel 22 .

[0032] Furthermore, when the locking device S is fastened, the top surface and side surfaces of the locking bottom 1 are covered by the locking surface 2 .

[0033] As can be seen from the above description, the positional relationship between the lock bottom and the lock surface makes the overall structure of the lock device more compact.

[0034] Furthermore, relative to the bottom surface of the lock bottom or the bottom surface of the third panel, the first inclined side surface 11 and the second inclined side surface 231 are located on the same side of their respective bottom surfaces.

[0035] From the above description, it can be seen that, firstly, the overall stability of the locking device after being fastened is increased, and secondly, the overall structure of the locking device is made more compact.

[0036] Furthermore, the first panel 21 and the second panel 22 are connected via a crease line or a hinge 24 .

[0037] Furthermore, the first inclined side surface 11 of the lock bottom 1 and the bottom surface 12 of the lock bottom 1 form a first angle A1 greater than 90 degrees, and the second inclined side surface 231 of the third panel 23 and the top surface 232 of the third panel 23 form a second angle A2 less than 90 degrees.

[0038] Furthermore, the sum of the first angle A1 and the second angle A2 is equal to or slightly less than 180 degrees.

[0039] It can be seen from the above description that the first inclined side surface 11 and the second inclined side surface 231 are matched with each other through their inclined surfaces, and the engagement is stable.

[0040] Furthermore, the first panel 21 , the second panel 22 and the third panel 23 of the locking bottom 1 and the locking surface 2 are all flat panels.

[0041] As can be seen from the above description, the overall structure of the locking device for the flat panel is simpler, the manufacturing cost is low, and the transportation and storage costs are also greatly reduced.

[0042] Furthermore, the thickness of the locking bottom 1 is equal to or slightly smaller than the thickness of the third panel 23 .

[0043] It can be seen from the above description that, firstly, the stability of the engagement between the first inclined side surface 11 and the second inclined side surface 231 is increased, and secondly, the overall structure of the locking device is made more compact.

[0044] Further, the distance from the second inclined side surface 231 to the connection between the first panel 21 and the second panel 22 is equal to or slightly greater than the sum of the length of the first panel 21, the length of the latch base 1, and the distance between the latch base 1 and the first panel 21.

[0045] As can be seen from the above description, firstly, the overall stability after the latch device is latched is increased, and secondly, the overall structure of the latch device is made more compact. Further, the latch device is made of a flexible material.

[0046] As can be seen from the above description, the latch device made of a flexible material ensures the appropriate tension of the entire latch device.

[0047] Further, the flexible material includes a paper material or a plastic material.

[0048] As can be seen from the above description, firstly, the manufacturing cost is saved, and secondly, the use of environmentally friendly materials facilitates recycling.
