Description

Technical Field

[0001] The utility model relates to the field of anti-counterfeiting packaging, and in particular to a snap-fitting piece, a buckle body, an anti-counterfeiting buckle and a packaging box. Background Art

[0002] The packaging box has the functions of protecting goods, conveying product information, and promoting goods. It generally includes a box body and a cover body. The box body and the cover body are detachably connected. The packaging box usually does not have an anti-counterfeiting function. After the packaging box is opened, it can be repacked as it was, so that counterfeiters put fake products instead of the original products into the packaging box, and then reassemble the box body and the cover body, thereby deceiving consumers and causing adverse effects on the reputation of the original manufacturer. Therefore, it is necessary to provide an anti-counterfeiting buckle structure between the box body and the cover body of the packaging box to prevent counterfeiting and reduce the possibility of the packaging box being easily opened without damage.

[0003] The lid and body of a traditional packaging box are fastened together with an anti-counterfeiting buckle, but there are many ways to open the lid of a wine box. There are two mainstream ways: 1. The lid and the box body are separated, and the lid body is locked vertically from the top of the box body; 2. The lid body is connected to one side of the box body, and the lid body is flipped and locked from the connection side. In order to use the same anti-counterfeiting buckle to meet both scenarios at the same time, it is usually necessary to increase the width of the corresponding buckle body's receiving slot to facilitate the buckle body to be inserted obliquely from one side.

[0004] However, due to the large width of the receiving groove, the buckle body still has a certain amount of room to move when it is engaged in the receiving groove, so that a gap can be formed between the box cover and the box body by applying force, allowing counterfeiters to insert tools through the gap to open the anti-counterfeiting buckle.

DETAILED DESCRIPTION

[0071] The utility model is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the utility model, but do not limit the utility model in any form. It should be pointed out that for those of ordinary skill in the art, several changes and improvements can be made without departing from the concept of the utility model. These all belong to the protection scope of the utility model.

[0072] Example 1

[0073] like Figure 1 , Figure 2 and Figure 3 As shown, a snap-fitting member 2 mainly comprises three parts: a first fixing portion 201, an extension portion 207 and a first buckle body 200. One end of the extension portion 207 is connected to the first fixing portion 201, and the other end is a free end, which together with the first fixing portion 201 forms a first snap-fitting groove 208. Figure 1 As shown, both sides of the first slot 208 may be open. In other embodiments, both sides of the first slot 208 may be closed or semi-closed, thereby reducing / avoiding the possibility that counterfeiters insert tools into the first slot 208 from both sides. Fig.11 As shown, the closed type is that the two sides of the first slot 208 are connected to the first fixing portion 201 and the extension portion 207 through the shielding portion to achieve complete closure. The semi-closed type can be as follows Fig.12 , Fig.13 , Fig.14 and Fig.15In this way, the openings on both sides are blocked and closed by a blocking portion connected to only one of the first fixed portion 201 and the extension portion 207: the blocking portion 212 is connected to the first fixed portion 201 and extends toward the extension portion 207; or, the blocking portion 212 is connected to the extension portion 207 and extends toward the first fixed portion 201; or, the blocking portion 212 includes a first blocking portion 210 and a second blocking portion 211, the first blocking portion 210 is connected to the first fixed portion 201 and extends toward the extension portion 207, and the second blocking portion 211 is connected to the extension portion 207 and extends toward the first fixed portion 201.

[0074] The first buckle body 200 is located in the first slot 208 and is connected to the first fixing portion 201 and / or the extension portion 207, wherein along the direction from the slot opening to the bottom of the first slot 208, the first buckle body 200 sequentially includes: a guide portion 203 and a limiting portion 205, and the connection between the guide portion 203 and the limiting portion 205 forms a first clamping portion 204.

[0075] like Figure 1 and Figure 3 As shown, the free end of the extension portion 207 is connected to a guide portion 206, and the top of the guide portion 206 is tilted in a direction away from the surface of the first fixing portion 201. Specifically, the tilting degree is greater than or equal to half of the thickness of the side wall of the box cover / box body. On the one hand, the opening size of the first card slot 208 is increased, and on the other hand, the guide portion 206 is an arc surface, which plays a certain guiding role, so that the engaging member can be inserted into the buckle body.

[0076] The guide portion 203 may be connected to the guide portion 206, and the present invention does not limit this. Figure 4 As shown, the guide portion 203 includes a sliding contact portion 2031 , a transition portion 2032 and a main body portion 2033 which are connected in sequence along the direction from the slot opening to the slot bottom of the first slot 208 .

[0077] The surface of the sliding contact portion 2031 is an arc surface, so as to facilitate sliding on the surface of the receiving groove. The width of the main body portion 2033 near the limit portion 205 is greater than the width of the limit portion 205 near the main body portion 2033, thereby forming the first clamping portion 204, and the width of the transition portion 2032 gradually increases from the end connected to the sliding contact portion 2031 to the end connected to the transition portion 2032. Figure 3 As shown, the inclination angle α of the transition portion 2032 is preferably less than or equal to 120 degrees. When the engaging member is inserted into a receiving groove, the sliding contact portion 2031 can slide and rub on the surface of the receiving groove, and the transition portion 2032 reduces / avoids the interference between the main portion 2033 and the receiving groove, thereby guiding the first buckle body 200 into the receiving groove.

[0078] The first clamping portion 204 is in the shape of a barb, and can be directly formed by using different width designs of the connecting portion between the guiding portion 203 and the limiting portion 205 .

[0079] The width of the limiting portion 205 gradually increases from the notch to the bottom of the notch, and its side surface can be an inclined surface or a Figure 2 The arc surface shown can achieve mutual interference and limitation with the openings of receiving grooves of different opening sizes.

[0080] In order to increase the degree of firmness of the engagement of the engaging member in the receiving groove of a buckle body, the surface of the first fixing portion 201 or the extension portion 207 is connected with a second buckle body 202, and the second buckle body 202 is located in the first buckle groove 208. At the same time, the buckle body needs to be provided with a corresponding buckle groove to engage with the second buckle body 202. The second buckle body 202 can be trapezoidal or hook-shaped.

[0081] like Figure 3 As shown, the first fixing part 201 is used to connect to the surface or interlayer of the packaging box. In order to increase the firmness of the fixation, a positioning protrusion 209 is connected to the surface of the first fixing part 201 outside the first card slot 208. At the same time, a positioning hole needs to be synchronously set on the packaging box, and the positioning protrusion 209 is inserted into the positioning hole. The number of the second buckle body 202 and / or the positioning protrusion 209 is one or more, and the utility model does not limit this. The positions of the multiple second buckle bodies 202 and / or the positioning protrusions 209 can be set arbitrarily, preferably, they are set in mirror symmetry with the first buckle body 200 as the symmetry axis.

[0082] In order to further reduce / avoid the possibility of external tools being inserted into the first slot 208, the engaging member further includes a shielding portion, which is connected to the first fixing portion 201 and / or the extension portion 207 and is located at the openings on both sides of the first slot 208, shielding the first buckle body 200 at the openings. Specifically, there are many connection positions for the shielding portion, as long as it plays a shielding role. This embodiment provides the following different methods:

[0083] The shielding portion is connected to the first fixed portion 201 and the extension portion 207; or, the shielding portion is connected to the first fixed portion 201 and extends toward the extension portion 207; or, the shielding portion is connected to the extension portion 207 and extends toward the first fixed portion 201; or, the shielding portion includes a first shielding portion 210 and a second shielding portion 211, the first shielding portion 210 is connected to the first fixed portion 201 and extends toward the extension portion 207, and the second shielding portion 211 is connected to the extension portion 207 and extends toward the first fixed portion 201.

[0084] Example 2

[0085] like Figure 5 , Figure 6 and Figure 7As shown, a buckle body 1 adapted to Example 1 mainly includes two parts: a second fixing portion 105 and a second clamping portion 103. The second fixing portion 105 is used to fix the buckle body 1 as a whole on the box body. The second fixing portion 105 can be bonded to the surface of the box body, or the second fixing portion 105 can be pre-buried inside the box body. In order to facilitate connection and fixation, the second fixing portion 105 is preferably a flat plate structure.

[0086] A receiving groove 106 is provided on one side of the second fixing portion 105, and the second clamping portion 103 is disposed in the receiving groove 106. The second clamping portion 103 divides the receiving groove 106 into a clamping portion receiving section 1061 and a buckle body receiving section 1062 from the groove opening to the groove bottom. One end of the second clamping portion 103 is connected to the inner wall of the receiving groove 106, and the other end is a free end and extends toward the buckle body receiving section 1062. The opening width of the clamping portion receiving section 1061 gradually increases from the free end of the second clamping portion 103 to the groove opening of the receiving groove 106. The opening width of the clamping portion receiving section 1061 is relatively large, and the opening width gradually decreases inwardly along the second clamping portion 103, which can guide the buckle body inserted obliquely and guide it into the buckle body receiving section 1062. Therefore, even if the buckle body does not face the buckle body receiving section 1062 of the receiving groove 106 vertically during the insertion process, it can normally enter the buckle body receiving section 1062 to complete the engagement under the guidance of the second clamping portion 103. The shape of the notch from the free end of the second clamping portion 103 to the receiving groove 106 is adapted to the limiting portion 205 in Example 1.

[0087] There are two second clamping parts 103, which are mirror-symmetrically arranged on the inner walls on both sides of the opening of the receiving groove 106. In order to facilitate the introduction of the buckle body, the second clamping part 103 is preferably an arc-shaped structure and / or an elastic structure. At the same time, the second clamping part 103 uses its own elasticity to be forced to open when the buckle body is inserted, and recovers at the position where the buckle body is clamped, thereby completing the clamping with the buckle body. In order to facilitate the movement of the second clamping part 103, an activity space 1063 is reserved between the second clamping part 103 and the clamping part receiving section 1061 for the elastic deformation of the second clamping part 103. In order to increase the firmness of the clamping, the free end of the second clamping part 103 can be designed to be hook-shaped. Figure 6 As shown, the corner 1031 of the second clamping portion 103 at least on the side facing away from the inner wall of the clamping portion receiving section 1061 is rounded, and the side facing away from the inner wall of the clamping portion receiving section 1061 is rounded. Figure 6 The side where the middle shaded line is located has a rounded corner 1031 between the side and the other side of the second clamping part 103, and the radius of the rounded corner is greater than or equal to one-third of the thickness of the second clamping part 103, thereby reducing / avoiding the possibility of the buckle body being worn by the corner when sliding on the surface of the second clamping part 103, and at the same time can improve the smoothness of the buckle body sliding. The thickness refers to the thickness perpendicular to Figure 5The height in the direction of the plane where the second fixing portion 105 is located.

[0088] In this way, when the buckle body is engaged with the buckle body, the buckle body cannot be pulled out in the opposite direction. Without damaging the packaging box, the buckle body and other structures, or without external force causing permanent deformation of the packaging box, the packaging box cannot be opened. This can well protect the packaging box, reduce / avoid the possibility of being pried open, and achieve the purpose of increasing the difficulty of counterfeiting. In addition, considering that counterfeiters can use slender tools to reach into the buckle body through the gap of the packaging box to pry open the buckle body, such as Figure 6 , Figure 7 As shown, the inner wall of the receiving groove 106 of this embodiment extends to one side or both sides in a direction away from the surface of the second fixing portion 105 to form a protrusion 104, that is, Figure 7 As shown, the protrusion 104 can protrude in the X direction, the Y direction, or in both the X and Y directions. In this way, the protrusion 104 can shield the buckle body and the second clamping portion 103, reducing / avoiding the possibility of being touched by tools. The second clamping portion 103 can extend in the X direction and the Y direction like the receiving groove 106, and the surface of the second clamping portion 103 does not exceed the protrusion 104.

[0089] One or more positioning posts 101 are provided on the surface of the second fixing portion 105 , and the positioning posts 101 can be arbitrarily arranged on the outside of the receiving groove 106 . Preferably, an even number of positioning posts 101 can be arranged in a mirror-symmetrical manner with the receiving groove 106 as the axis of symmetry, and are used to be passed through the packaging box to assist in fixing the second fixing portion 105 .

[0090] The surface of the second fixing portion 105 is also provided with one or more second slots 102, which can be arbitrarily arranged outside the receiving slot 106. Preferably, an even number of second slots 102 can be arranged in a mirror-symmetrical manner with the receiving slot 106 as the symmetry axis, and are used to engage with the second buckle body 202 of the engaging member, thereby increasing the degree of firmness of the engagement between the engaging member and the buckle body. At the same time, in the engaged state, the second slots 102 on both sides of the receiving slot 106 and their buckles can limit the space for tools to be inserted, further reducing / avoiding the possibility of tools being inserted into the receiving slot 106 to pry open the second clamping portion 103, and also limiting the displacement of the engaging member.

[0091] Preferably, the shape of the buckle body 1 is adapted to the space in the first slot 208, so that the second clamping portion 103 enters the first slot 208 as deeply as possible within the controllable range of its elastic deformation, and the second clamping portion 103 of the buckle body 1 engages with the first clamping portion 204 while abutting against the limiting portion 205, thereby limiting the position of the engaging member 2 and reducing / avoiding the displacement of the engaging member 2. Without affecting assembly, the buckle body 1 occupies the first slot 208 as much as possible, so that the space in which the buckle body 1 and the engaging member 2 can move relative to each other is reduced as much as possible when the buckle body 1 and the engaging member 2 are in a mutually engaged state.

[0092] Example 3

[0093] like Fig.10 As shown, an anti-counterfeiting buckle comprises the buckle body 1 described in Example 2 and the engaging member 2 described in Example 1. The engaging member can be inserted into the buckle body from different angles and can be effectively introduced into the receiving groove to achieve engagement. It can be applied to both vertically inserted box covers / box bodies and box covers / box bodies that rotate from one side. There is no need to design the structures of the buckle body separately, thus saving costs.

[0094] Example 4

[0095] like Figure 8 , Fig. 9 and Fig.10 As shown, a packaging box 3 includes the anti-counterfeiting buckle described in Example 3, a box cover 301, and a box body 302. The buckle body 1 is arranged on one or more side walls of the box cover 301 / box body 302, and the engaging member 2 is correspondingly arranged on one or more side walls of the box body 302 / box cover 301.

[0096] The box cover 301 and the box body 302 may be separate structures, so that when closing the box cover, the buckle body of the locking member 2 can be directly inserted into the receiving groove 106 of the buckle body 1 in the vertical direction.

[0097] The box cover 301 and the box body 302 may also be a rotating connection structure connected at one side, and one side of the box cover 301 can be rotatably connected to one side of the box body 302. When the box cover 301 is turned over, the buckle body of the engaging member 2 first contacts the opening position of the clamping portion receiving section 1061, and then further enters the buckle body receiving section 1062 under the guidance of the second clamping portion 103, thereby completing the engagement.

[0098] The box cover 301 / box body 302 may be a multi-layer structure, and the first fixing portion 201 and the second fixing portion 105 may be connected to the surface of the multi-layer structure, or may be pre-buried in the multi-layer structure, and the remaining parts are exposed outside the box cover 301 / box body 302. The box cover 301 / box body 302 is also connected to the surface of the box body / box cover.
