Description

Technical Field

[0001] The present disclosure relates to the technical field of packaging parts, and specifically to a paper buckle. Background Art

[0002] In the packaging industry, in order to facilitate the packaging of large and heavy products, upper and lower card sleeve or wrapping packaging is adopted. Such packaging needs to be locked with a buckle so that the outer packaging boxes can be combined together to form a closed integral structure. For many heavy-duty anti-theft packages or packages that need to be sealed, a rotary buckle is often used to lock the opening to improve the stability of the packaging opening.

[0003] Also, the rotary buckle is usually made of plastic or metal. The plastic rotary buckle will generate a large amount of pollutants and toxic substances during the production process, and it is difficult to degrade, which is easy to cause harm to the environment. The commonly used plastic buckles on the market no longer meet the market requirements in terms of environmental protection with the trend of packaging plastic removal; some use pulp molding, but the load-bearing capacity is relatively weak, and for the metal rotary buckle, the cost is difficult to control; in addition, for the packaging using a rotary buckle, when recycling, the rotary buckle needs to be separated from the packaging body first, which increases the recycling cost of the packaging.

[0031] Next, the technical solutions in the embodiments of the present disclosure will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present disclosure.

[0032] As Figure 1 shown, a paper buckle provided in this embodiment can be applied to heavy packaging or packaging that needs to be sealed to improve the stability of the opening of the packaging.

[0033] As Figures 2 - 4 shown, a paper buckle includes:

[0034] A first component 1, in the shape of a cube, specifically a cuboid, which includes a first square groove 11 provided on one side surface, a first locking groove 13 provided on another side surface, and a first locking channel 12 communicating with it; the top surface of the first component 1 is an open opening, and the first locking channel 12 communicates with the first opening 14;

[0035] A second component 2, sleeved outside the first component 1, includes a second square groove 21 provided on one side, a second locking groove 23 provided on the other side, and a second locking channel 22 communicating with it. The positions of the first locking groove 13 and the second locking groove 23 are both circular and coincide in position. The side surface of the second component 2 is an open opening, and the second locking channel 22 communicates with the second opening 24;

[0036] Both the first locking groove 13 and the second locking groove 23 are strip-shaped and cross-shaped. The strip-shaped outer shape is beneficial to the translational movement of the rotating part 31 mentioned below, and the circular outer shape is beneficial to the rotational movement of the rotating part 31.

[0037] Furthermore, arc chamfers are provided at the beginning of the first locking track 12 and the second locking track 22 , so that they will not be damaged too quickly due to frequent contact and force during assembly, and it is also convenient for inserting the rotating part 31 .

[0038] The third component 3 has a raised rotating portion 31 on its surface in a stepped shape. On the one hand, it beautifies the shape. On the other hand, due to the thickness of the paper structure, the rotating portion 31 will conflict with it when it moves. The stepped setting cancels part of the structure on its edge, thereby staggering the paper structure during movement, and will not hinder the rotational and translational movements of the rotating portion 31.

[0039] The rotating portion 31 passes through the first lock channel 12 and is confined in the first lock groove 13, and is exposed in the first square groove 11 and the second square groove 21, so that the operator can pinch the rotating portion 31 by hand. In addition, a reinforcing plate 32 is provided on the back of the third component 3 to strengthen the back strength of the third component 3 to prevent bending, deformation, etc., which affect the structural strength.

[0040] The following is the production process and assembly process of each component:

[0041] The first component 1, the second component 2 and the third component 3 are all formed by punching out rectangular paper tubes, which is quick and convenient. The reinforcing plate 32 is formed by a whole piece of rectangular gray paperboard.

[0042] like Figure 5 As shown, the rotating portion 31 of the second member 2 is placed in the same direction as the first square groove 11 of the first member 1 , inserted from the first opening 14 , and passed through the first locking channel 12 and confined in the first locking groove 13 .

[0043] like Figure 6 As shown, the second square groove 21 of the third component 3 is placed in the same direction as the first square groove 11 of the first component 1, the second opening 24 is aligned with the first component 1, the second locking channel 22 is aligned with the stepped rotating portion 31, and the third component 3 is inserted into the second component 2, and the positions of the first square groove 11 and the second square groove 21 are adjusted so that the two overlap. At this time, the first locking channel 12 and the second locking channel 22 are in a cross shape, and the first opening 14 of the first component 1 is closed by the second component 2, and the second component 2 cannot be detached from the first component 1.

[0044] The rotating part 31 is rotated to drive the third component 3 to rotate 90° as a whole, and the base part is perpendicular to the second component 2 to form a lock.

[0045] like Figure 10As shown, restore the buckle in Step 3, that is, rotate it 90° in the reverse direction. Otherwise, it cannot be installed into the carton. Align the paper buckle with the holes of the outer carton and the bottom cover, and insert it into the inside. The cross-sectional area of the second member 2 is larger than the cross-sectional area of the carton hole, so that the whole buckle can be prevented from falling into the carton.

[0046] As Figure 11 shown, after the whole buckle is inserted into the carton, rotate the rotating part 31 to set the state of the third member 3 perpendicular to the second member 2, and the locking of the carton can be completed.

[0047] Furthermore, the first member 1, the second member 2, and the third member 3 can be formed not only by stamping with mechanical equipment but also by gluing.

[0048] As Figure 7 shown, it is the cardboard unfolding diagram of the first member 1. Apply glue evenly on the surfaces of both sides of the cardboard, use the fitting machine track to fold the two sides of the cardboard inward, and stack them into a cuboid with a certain thickness. Then, straighten the two sides of the first member 1 to be in a vertical state, as shown in the figure.

[0049] As Figure 8 shown, it is the cardboard unfolding diagram of the second member 2. Apply glue evenly on the surfaces of both sides of the cardboard, use the fitting machine track to fold the two sides of the cardboard inward, and stack them into a cuboid with a certain thickness. Then, straighten the two sides of the first member 1 to be in a vertical state.

[0050] As Figure 9 shown, it is the cardboard unfolding diagram of the third member 3. Apply glue evenly on the surfaces of both sides of the cardboard, use the fitting machine track to push the two sides of the cardboard inward, then the middle part bulges upward to form the rotating part 31, and then attach the grey cardboard to its back to complete the molding.

[0051] The above is only the specific implementation manner of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present disclosure can easily think of changes or substitutions, which should all be covered within the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be subject to the protection scope of the claimed rights.
