Description

Lock catch female head, lock catch male head, anti-counterfeiting lock catch structure and packaging box

The present application is based on the following prior patent applications:

application number: 202311120217.1

Filing date: 2023-08-31

Patent name: lock catch female head, lock catch male head, anti-counterfeiting lock catch structure and packaging box

Technical Field

The invention relates to an anti-counterfeiting technology of a packaging box, in particular to a locking female head, a locking male head, an anti-counterfeiting locking structure and the packaging box.

Background

In order to avoid the counterfeiting of the product, the anti-counterfeiting label is arranged on the package of the product, so that the anti-counterfeiting label has a certain suppressing effect on the counterfeiting action. However, not all products are suitable as a means of security labels. Taking white spirit as an example, the traditional mode is to verify the authenticity of a product by designing an anti-counterfeiting label on a bottle cap. However, there have been illegal molecules that unpack the wine in the bottle by drilling holes in the body of the bottle, making it difficult for consumers to identify the wine at the time of purchase. Therefore, a technique for further anti-counterfeiting the packaging box outside the product is produced in the market.

Fig. 1 and fig. 2 are prior anti-counterfeiting buckle structures, in which a clamping piece 2 mounted on a side plate of a box cover of a packaging box is inserted into a clamping groove 104 of a buckle body 1 mounted on a side edge of a box body, so that a dead buckle is formed between a clamping hole on the clamping piece 2 and a buckle body 105 on the buckle body 1, the packaging box can be opened only by destroying the integrity of the box body and the box cover, and the difficulty of falling and counterfeiting of internal products is greatly increased. Although the structural design provides an anti-counterfeiting thought, the structural design still has obvious defects in the actual use process: in order to increase the fastening firmness, the fastening member 2 is usually made of a metal sheet, and the fastening body 1 may be made of plastic or metal. Because the material of lid and box body is soft, and has certain clearance, consequently the lid is pried up a take level easily, and the card hole bottom limit of fastener 2 will contact on buckle 105's bottom surface this moment, if constantly make a round trip movement fastener 2 in the direction of vertical in the plane of figure 1, sharp card hole edge will make a round trip cut buckle body 105, finally makes buckle body 105 cut off. At this time, the package can be opened to remove the inner product, and then the button body 105 is stuck back and the box cover is fastened. At this time, the consumer can only see that the whole structure of the package is good, so that the consumer considers the internal product as a genuine product, but hardly notices that the internal structure of the buckle body 1 is damaged. To avoid or reduce this possibility, the present invention provides a new structural design.

Detailed Description

The present invention will be described in detail with reference to specific examples. The following examples will assist those skilled in the art in further understanding the present invention, but are not intended to limit the invention in any way. It should be noted that variations and modifications could be made by those skilled in the art without departing from the inventive concept. These are all within the scope of the present invention.

Example 1

As shown in fig. 3 and 4, the latch female includes: a mounting portion 101, a first connection portion 102, and a second connection portion 103. The mounting portion 101 is used for connecting a first component to be packaged, such as a case body of a case. The first connecting portion 102 is connected to the mounting portion 101, the second connecting portion 103 is connected to the first connecting portion 102, and the first connecting portion 102 serves as a bottom of the clamping groove 104, together forming the clamping groove 104. In the clamping groove 104, the buckle body 105 is connected to the first connecting portion 102 or the mounting portion 101, and the bottom surface of the buckle body 105 is a contact surface which contacts with the buckling hole and is mutually buckled. The number of the buckles is one, and in other embodiments, the buckles can be multiple. An elastic supporting leg 106 is provided on the mounting portion 101 or the first connecting portion 102 opposite to the fastening body 105, for pressing the inserted second member in a direction in which the fastening body 105 is located, so that the fastening body 105 and the fastening hole are in an effective fastening state. The number of the elastic supporting legs 106 is one or more, preferably two, and the second parts are respectively pressed against the side of the buckle body 105 from the left side and the right side. In other embodiments, the number may be 3, 4, or the like, and in the case of 3, the second member may be pressed against the side of the buckle body 105 from the corresponding vertex angle position in the form of an equilateral triangle, and in the case of 4, the second member may be pressed against the side of the buckle body 105 from the corresponding vertex angle position in the form of a square. One end of the second connecting portion 103 is connected to the first connecting portion 102, and the other end is tilted toward a direction away from the mounting portion 101, thereby facilitating insertion of the second component.

Further, an elastic pull-out preventing leg is connected to the mounting portion 101 and the second connecting portion 103 on the same side as the elastic support leg 106, and is positioned opposite to the buckle 105. The elastic anti-pulling leg is similar to the elastic supporting leg 106 in structure, but is not supported by the buckling hole because the movable end of the elastic anti-pulling leg is located at the buckling hole in a state where the first member is engaged with the second member in opposition to the buckling body 105. However, when the male end of the lock catch is pried away from the buckle body, the buckle Kong Youhui is clamped by the elastic anti-pulling pin, so that the first component and the second component cannot be separated, and the anti-prizing effect is enhanced. In order to increase the contact area of the button body 105 with the corresponding button hole, the width (left-right direction in fig. 3) of the button body 105 is designed to be at least 2.5mm, and an excessively wide width may cause difficulty in male insertion, so that the width of the button body 105 is preferably designed to be 4.5mm to 7mm.

In the clamping groove 104, the limiting part 108 is arranged on the inner wall of the clamping groove 104 where the elastic supporting leg 106 is located, the height of the elastic supporting leg 106 is higher than that of the limiting part 108, the protruding part extends towards the inner wall where the buckle body 105 is located, a certain limiting effect is achieved, the elastic supporting leg 106 is prevented from being extruded in a transitional mode, the gap between the limiting part 108 and the buckle body 105 is guaranteed to be larger than or equal to the width of the second component, and the movable space of the second component in the clamping groove is reduced.

Example 2

As shown in fig. 11, since the package is usually made of paper, the first fastening hole 301 formed directly on the package is easily damaged during pulling, so the present embodiment provides a male fastener for use with the female fastener of embodiment 1.

The male locking device is of a metal sheet structure and comprises second locking holes 201 corresponding to the first locking holes 301 respectively. The male latch portion is embedded in the second member or attached to the surface of the second member such that the first latch aperture 301 and the second latch aperture 201 overlap each other. In order to increase the firmness of the connection, the latch male further comprises a second bending part 204, the second component comprises a mounting groove matched with the second bending part 204, and the second bending part 204 is used for being inserted and fixed in the mounting groove. The side of the second bayonet 7 can be in surface contact with the buckle 105, so that a limit is formed, and the limit means that the buckle is damaged and moved by cutting the buckle after the clamping piece is clamped. The edge of the second button hole 201 includes a cut-resistant contact structure with the contact surface of the button body 105. Specifically, the edge of the second buckling hole 201 may be provided with a first bending portion 202 facing away from the direction where the buckling body 105 is located, so as to increase the contact area with the contact surface of the buckling body 105, or the edge angle of the edge of the second buckling hole 201 may be designed to be a smooth arc surface, or the thickness of the second buckling hole 201 (the thickness of the first bending portion 202 is added in the case of the first bending portion 202, i.e. the thickness indicated by the letter a in fig. 15) may be increased to be equal to or greater than 0.3mm, so that the buckling hole edge cannot cut the buckling body 105, and the maximum thickness thereof is designed according to the actual cost and the actual application scenario, and in the packaging box field of the present invention, the thickness is preferably not greater than 2mm.

As shown in fig. 12, in a state where the first component to be packaged is packaged with the second portion, the contact surface of the buckle body 105 contacts with the anti-cutting contact structure of the second buckle hole 201 to form a clamping engagement, and the elastic supporting leg 106 presses the second component towards the direction of the buckle body 105 under the action of self elastic force. Because the second buckling hole 201 is rectangular, the edge of the buckling hole is in surface contact with the buckling body, and the surface contact area is larger by the design of the invention, the buckling body is difficult to cut, and the firmness of the buckling is ensured. In the case that the number of the fastening bodies is plural, the plural fastening bodies 105 correspond to one first fastening hole, or one fastening body corresponds to one first fastening hole.

Example 3

The present invention provides an anti-counterfeiting lock catch structure, which is based on embodiment 1 and embodiment 2, as shown in fig. 3 and fig. 5 to 8, in order to prevent a prying tool from extending into a clamping groove 104 from a gap between a box cover and a box body, side blocking parts 107 are arranged at openings at two sides of the clamping groove 104. In the present invention, the side guard 107 may be connected to the mounting portion 101 and extend toward the second connection portion 103 to cover the opening of the card slot 104, or the side guard 107 may be connected to the second connection portion 103 and extend toward the mounting portion 101, or the extending end may be connected to the mounting portion 101 or the second connection portion 103, or may not be connected thereto, and the present invention is not limited thereto. In other embodiments, the side blocking portion 107 may be divided into two parts, that is, a first side blocking portion 1071 and a second side blocking portion 1072, where the first side blocking portion 1071 is connected to the mounting portion 101 and extends toward the second connecting portion 103, and the second side blocking portion 1072 is connected to the second connecting portion 103 and extends toward the mounting portion 101, and the first side blocking portion 1071 may be inside or outside the second side blocking portion 1072. The surfaces of the side stopper 107, the first connecting portion 102 and the second connecting portion 103 may be provided with reinforcing ribs.

The male latch head further includes a second guide slot 203, and the male latch head is embedded in the second member or attached to the surface of the second member, so that the first guide slot 302 and the second guide slot 203 overlap each other. In a state where the first member to be packaged and the second portion are packaged, the side stoppers 107 are inserted into the second guide grooves 203, respectively, to restrict lateral movement of the second member.

As shown in fig. 9, the side blocking portion 107 has a gathering region 1073, and the area of the notch of the slot 104 in the gathering region 1073 gradually decreases in a direction away from the first connecting portion 102. The angle of the prying tool is limited by the folding area, and the prying tool can be inserted into the clamping groove only at a limited angle, for example, 45-60 degrees, so that the prying tool is better prevented from touching the buckle body after being obliquely inserted into the clamping groove.

As shown in fig. 10, the bottom surface of the buckle body 105 is a contact surface contacting with the clamping hole, a damage prompting structure is arranged on the buckle body 105, and specifically, a containing space is arranged in the buckle body 105, and the containing space is filled with a dyeing material. In the event of damage to the button 105, the inner coloring material may flow out. Correspondingly, a hollowed-out structure is arranged at the position of the first connecting part 102, which is opposite to the buckle body 105, and the flowing dyeing material can enter the packaging box from the hollowed-out structure, so that the inner wall of the box body is dyed, and the warning effect is achieved.

In a state where the first component to be packaged and the second component are packaged, the buckle body 105 is engaged with the first buckle hole 301 formed in the second component, the first buckle hole 301 is rectangular, the elastic supporting leg 106 supports the second component towards the direction of the buckle body 105 under the action of self elasticity, and the side blocking parts 107 are respectively inserted into the first guide grooves 302 in the second component. Thus, the anti-counterfeiting lock catch structure is formed.

Example 5

Taking a packaging box as an example, as shown in fig. 12 to 15, a locking female head is connected to the inner wall of the box body 4/the side plate of the box cover 3, and a locking male head is connected to the inner wall of the corresponding side plate of the box cover 3/the box body 4 or a clamping structure is directly prepared. The number of the locking female heads and the locking male heads/clamping structures can be one, or can be two, three or four, and the locking female heads and the locking male heads/clamping structures are arranged on different surfaces of the box body.

As shown in fig. 6, the box body is formed by compounding a plurality of layers of paper boards, and at least part of the periphery of the male latch is covered by the paper boards. The mounting part is fixedly mounted on the side plate of the box body/box cover in an adhesive, clamping or embedding way.

When the box cover is covered on the box body, the buckling body 105 on the side plate/box body of the box cover is clamped with the first buckling hole 301 or the second buckling hole 201 of the side plate/box body of the box cover, and the side blocking part 107 on the side plate/box body of the box cover is inserted into the first guide groove 302 or the second guide groove 203 of the box body/box cover to guide and limit. The region that sets up the installation department is provided with easily tears line 5, and the user can destroy the box body through easily tearing line 5 to open the lid and take out inside product.

Through the arrangement, under the condition that a counterfeiter prizes by external force of tools such as a steel ruler, the side plate of the cover body has strong perforable deformation capacity because of the embedded metal sheet, the deformation is very small, the packaging box is difficult to prize under the condition that the shell does not leave marks, and the packaging box is damaged by forced plugging in to damage the tearing opening. Meanwhile, the guide grooves on the side plates of the cover body are inserted into the side blocking parts on the locking female head, and meanwhile, the two sides on the side plates of the cover body are accommodated in the box body to form a cavity, so that the moving amount of the cover body is very small. Meanwhile, if an lawbreaker uses an iron wire to jack in from a gap on one side of the back of the box body and the side plate, the iron wire cannot be pried away from the lock catch male head due to deformation of the box cover on the other side caused by elastic supporting legs on the lock catch female head. Meanwhile, because of the improvement of the shape and the matching of the metal iron sheet on the box cover, the buckle cannot be damaged and cut no matter what the box cover is pulled left and right. The packaging box can not be opened under the condition that the structures such as the cover body and the anti-counterfeiting buckle are not damaged or the shell is permanently deformed due to external force. The technology can well protect the packaging box and prevent prying and damage.
