[0039] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.
[0040] The embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.
[0041] Combination Figure 1 and Figure 3 As shown, the embodiment of the present disclosure provides a self-locking carton, which includes a carton body 1; first flaps 11 are respectively provided in the two long sides of the bottom of the carton body 1; second flaps 12 are respectively provided in the two wide sides of the bottom of the carton body 1; wherein the first flap 11 has a first sub-segment 111 and a second sub-segment 112 of different widths along its own length direction, and a buckle card 13 is also provided at the connection between the two; the two first flaps 11 are centrally symmetrically arranged about the center of the carton body 1, and are respectively overlapped with the other second sub-segment 112 through their respective first sub-segments 111, and the two buckle cards 13 are respectively buckled and connected correspondingly.
[0042] When assembling the self-locking carton, the carton body 1 is first formed into a square ring shape, so that the first flaps 11 in the two long sides of the bottom of the carton body 1 can be arranged symmetrically about the center of the carton body 1, and the second flaps 12 in the two wide sides of the bottom of the carton body 1 can be arranged relatively, and the first sub-segment 111 in the first flap 11 can overlap with the second sub-segment 112 in the other first flap 11, and the buckle cards 13 in the two first flaps 11 can also be buckled and snapped respectively, so as to realize the mutual fixation of the two first flaps 11. At the same time, the two second flaps 12 can also be clamped and fixed under the condition that the two first flaps 11 are fixed to each other, so that the bottom wall of the carton body 1 is finally realized by "two first flaps 11 + two second flaps 12".
[0043] Compared with the common packaging cartons or self-locking cartons in the prior art, the self-locking carton provided by the embodiment of the present disclosure has a simple structure, does not require adhesive tape to be adhered, and can achieve stable fixed forming of the bottom wall of the carton by latching and snapping together the buckle cards 13. It has the beneficial effects of simple assembly process, firm latching, and will not be opened by external pressure, and good anti-dismantling safety performance.
[0044] In one embodiment, the buckle card 13 has a folded side edge 131 connected to the first flap 11, and a buckle side edge 132 protruding away from the first flap 11 along the length direction; the buckle card 13 can be flipped up and down around the folded side edge 131; when the buckle card 13 is locked, the buckle side edge 132 overlaps and blocks the first sub-segment 111 in the other first flap 11.
[0045] Specific, combined Figure 2 To further explain in detail, the buckle card 13 is provided with a folded side edge 131 connected to the first flap 11, and a buckle side edge 132 protruding away from the first flap 11 along the length direction, and the buckle card 13 can be flipped up and down around the folded side edge 131, thereby driving the buckle side edge 132 to overlap and block the first sub-segment 111 in another first flap 11, or no longer overlap and block the first sub-segment 111 in another first flap 11.
[0046] The specific configuration of the buckle card 13 has the beneficial effects of being simple in structure and being able to achieve self-overlapping and blocking by turning the folded side edge 131 up and down.
[0047] In one embodiment, the buckle card 13 further includes a flush side edge 133 flush with the length side of the first sub-segment 111 ; the folded side edge 131 , the buckle side edge 132 and the flush side edge 133 together form a triangle-shaped buckle card 13 .
[0048] Specific, combined Figure 2 To further explain in detail, a flush side edge 133 flush with the length side of the first sub-segment 111 is also provided in the buckle card 13, and the folded side edge 131, the buckle side edge 132 and the flush side edge 133 together form a triangular buckle card 13, so that the protrusion of the triangular buckle card 13 is provided at the connection transition point between the first sub-segment 111 and the second sub-segment 112, and forms an angle less than 90° with the second sub-segment 112, so that the two buckle cards 13 are buckled and connected with each other to form a stable self-locking fixing structure.
[0049] The specific configuration of the buckle card 13 has the beneficial effects of simple structure and stable self-locking in the buckle connection.
[0050] In one possible implementation, the angle between the folded side 131 and the flush side 133 is denoted as α; the angle between the buckled side 132 and the flush side 133 is denoted as β; and α<β, or α=β, or α>β is satisfied.
[0051] Specific, combined Figure 2To further explain in detail, the angle α between the folded side 131 and the flush side 133 can be specifically but not limited to 30°, and the angle β between the buckle side 132 and the flush side 133 can be specifically but not limited to 60°, at this time α<β, so that the buckle card 13 itself presents a right triangle shape, and the length of the buckle side 132 is the shortest, which can reduce the torque received when the buckle side 132 is buckled and connected with each other, thereby avoiding stress concentration on the buckle side 132 and irreversible destructive deformation; the angle α between the folded side 131 and the flush side 133 can be specifically but not limited to 45°, and the angle β between the buckle side 132 and the flush side 133 can be specifically but not limited to 45°, at this time α=β, so that the length of the folded side 131 is moderate, which can ensure the fatigue resistance of the buckle card 13 after multiple folding; the length of the flush side 133 is the longest, which can ensure the abutment stability of the buckle card 13 with the inner wall of the carton body 1.
[0052] In one embodiment, a connection between the buckle side edge 132 and the flush side edge 133 is provided with a rounded corner or a chamfered corner structure.
[0053] Specific, combined Figure 2 To further explain in detail, at this time, a chamfered structure is provided at the connection between the buckle side edge 132 and the flush side edge 133. Of course, a chamfered structure can also be provided at the connection between the buckle side edge 132 and the flush side edge 133. This can avoid sharp angles at the connection between the two. On the one hand, it can avoid damage to the packaged product caused by top piercing, and on the other hand, it can avoid the problem of stress concentration on the corners of the buckle card 13.
[0054] In one embodiment, the buckle side edge 132 is vertically connected to the folded side edge 131 , and is disposed between an end of the folded side edge 131 close to the second sub-segment 112 .
[0055] Specific, combined Figure 2 In further detail, the buckle side 132 is vertically connected to the folded side 131, and is disposed between the buckle side 132 and the folded side 131 at one end close to the second subsection 112. In this way, a reserved gap is generated between the buckle side 132 and one end of the folded side 131, and when the two buckle cards 13 are buckled and connected to each other, the reserved gap can allow the two buckle side 132 to avoid each other during the folding process, thereby avoiding the problem of mutual interference during the folding process.
[0056] In one embodiment, the first flap 11 and the second flap 12 are respectively connected integrally to the carton body 1 ; the first sub-segment 111 and the second sub-segment 112 are connected integrally, and the width of the first sub-segment 111 is greater than the width of the second sub-segment 112 .
[0057] Specific, combined Figure 1To further explain in detail, the first flap 11 and the second flap 12 are respectively connected to the carton body 1 as a whole, so that it is convenient to cut and shape the raw material cardboard into one piece; the first sub-segment 111 and the second sub-segment 112 are connected as a whole, so that the structural strength of the first flap 11 can be improved as a whole; the width of the first sub-segment 111 is set to be larger than the width of the second sub-segment 112, so that the buckle card 13 can be raised and set at the connection transition between the first sub-segment 111 and the second sub-segment 112, so as to facilitate the subsequent stable mutual buckle connection.
[0058] In one embodiment, an inserting portion 111 a is protruded from the long side of the first sub-segment 111 facing away from the carton body 1 ; the inserting portion 111 a can abut against the relative inner wall of the carton body 1 .
[0059] Specific, combined Figure 1 and Figure 3 Further detailed description, an insert portion 111a is protruded from the long side of the first sub-segment 111 facing away from the carton body 1, and the insert portion 111a can abut against the relative inner wall of the carton body 1, so that the insert portion 111a can further improve the supporting stability of the first sub-segment 111 and the inner peripheral wall of the carton body 1, so that the supporting and solidifying effect of the three-dimensional molding of the carton body 1 is better.
[0060] In one possible implementation, the plug-in portion 111 a is configured as a plug-in edge extending along the length direction of the first sub-segment 111 ; and the width of the plug-in edge is 1 to 2 times the thickness of the first flap 11 .
[0061] Specific, combined Figure 1 and Figure 3 To further explain in detail, the plug-in portion 111a is specifically configured as a plug-in edge extending along the length direction of the first sub-segment 111, and the width of the plug-in edge is 1 to 2 times the thickness of the first flap 11, so that the plug-in portion 111a itself has a certain structural strength, which can ensure that it will not be squeezed and collapsed by the inner wall of the carton body 1.
[0062] In one embodiment, a slot receiving opening 14 corresponding to the inserting portion 111 a is further formed in the inner wall of the carton body 1 ; the inserting portion 111 a can be at least partially inserted into the slot receiving opening 14 .
[0063] Specific, combined Figure 1 and Figure 3To further explain in detail, a slot receiving opening 14 corresponding to the plug-in portion 111a is further opened in the inner wall of the carton body 1, and the plug-in portion 111a can be at least partially plugged into the slot receiving opening 14. In this way, through the plug-in action of the plug-in portion 111a and the slot receiving opening 14, the connection stability between the first flap 11 and the inner wall of the carton body 1 can be further improved, so that the load-bearing capacity of the bottom wall of the carton body 1 formed by overlapping the two first flaps 11 and the two second flaps 12 is stronger.
[0064] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present disclosure, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.
[0065] The above is only a specific embodiment of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present disclosure, which should be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be based on the protection scope of the claims.
