Description

Technical Field

[0001] The utility model relates to the field of product paper packaging, in particular to a theft-proof two-piece board packaging carton with less material consumption. Background Art

[0002] In recent years, with the gradual popularization of online shopping, the commodity packaging industry has also developed vigorously, especially the packaging cartons used in the logistics and express delivery industry, which are widely used in product packaging in various industries, and the usage is increasing year by year. This kind of carton is generally a regular hexahedron structure formed by a single cardboard. Its packaging shape and design structure are relatively simple, and the packaging strength is insufficient. Most of them need to use plastic tape to help bond and seal the box. Its box formation is slow and cannot be self-fixed at all. When using tape to seal the box, it not only pollutes the box body, but also increases the packaging cost and affects the appearance. The sealing mouth is more difficult to open quickly, and sometimes other tools are needed to open the box body. In addition, there is no anti-theft structure at the sealing mouth. As long as the box body is open during storage and transportation, the goods inside are very easy to be stolen.

[0003] In order to solve the above problems, some methods have been developed in the industry to increase the number of cardboard layers or thickness on multiple sides of the packaging carton to enhance the packaging strength of the packaging carton. This will invisibly increase the material consumption of the packaging carton and the cost. Such packaging cartons are not very fast to unpack. Subsequently, tear strips are set on the top cover of the carton to help unpacking. However, since the end of the existing tear strip is flush with the top cover of the carton and fits on the top surface of the carton, it is not easy for the hand to grasp when unpacking, so it is still slightly insufficient for fast unpacking. At the same time, there are also many cartons in the industry that use the tongue inserted into the socket on the side of the top cover of the carton to prevent theft. However, due to the unreasonable structural design of the tongue and the socket, the gap between the tongue and the socket will be larger after the tongue is inserted into the socket, which also affects the compactness of the box packaging. In addition, the existing packaging cartons basically rarely carry out anti-theft treatment on the bottom of the box body of the packaging carton, which also affects the packaging safety of the entire packaging box.

[0004] In view of this, the inventor of the present invention conducted in-depth research on the above-mentioned defects in the prior art, and thus this case came into being. Utility Model Content

In this way, when the left top plugboard 113, the right top plugboard 114, the left bottom plugboard 133 and the right bottom plugboard 134 are respectively inserted into the upper left socket 5, the upper right socket 9, the lower left socket 6 and the lower right socket 10, the rear sides of the ends of the left top plugboard 113, the right top plugboard 114, the left bottom plugboard 133 and the right bottom plugboard 134 will first enter the wider mouth surface parts of the rear sides of the upper left socket 5, the upper right socket 9, the lower left socket 6 and the lower right socket 10 respectively, and then the ends of the left top plugboard 113, the right top plugboard 114, the left bottom plugboard 133 and the right bottom plugboard 134 will enter the entire gaps of the upper left socket 5, the upper right socket 9, the lower left socket 6 and the lower right socket 10 respectively from back to front very smoothly, thereby making it easier to insert.

[0054] At the same time, the entire upper edge of the top cover 11 is in a wavy structure, and a wavy side edge is formed, and after the upper double-sided tape 3 is pasted on the top cover 11, its upper side edge is flush with the upper edge of the wavy side edge. This makes the top cover 11 not fully overlapped, and the wavy edge is made on the premise of saving paper, making the top of the packaging carton beautiful, and with the straight edge release paper of the double-sided tape 3, it is easy to tear open for use.

[0055] When opening the box, people only need to open the handle 142 with their fingers and hold it to pull it upwards, and the connection between the tear structure 14 and the front side plate 22 will break along the dotted line of the punching process, and the tear structure 14 will be separated from the front side plate 22. Then continue to pull upwards, the tearing part 141 of the tear structure 14 drives the front upper lining plate 221 to be forced upwards, so that the two ends of the upper side of the tearing part 141 extend to both sides and break at the dotted line punching process, so that the front upper lining plate 221 can drive the top cover 11 to open from the top of the packaging carton.

[0056] Example 3.

[0057] like Fig. 9 As shown, a theft-proof two-panel packaging carton with less material consumption includes an A panel structure 1 and a B panel structure 2;

[0058] The A panel structure 1 includes a top cover 11, a rear side panel 12 and a bottom panel 13 connected in sequence from top to bottom. The top cover 11 has an upper double-sided tape 3 bonded to the inner side of the entire edge of the upper side.

The left and right sides of the lower part of the top cover 11 are respectively connected to the left top plug plate 113 and the right top plug plate 114; the left and right sides of the rear side panel 12 are respectively connected to the left rear plug plate 121 and the right rear plug plate 122; a rectangular notch 15 is opened in the middle of the lower side of the bottom panel 13, and the lower double-sided tape 4 is bonded to the lower side of the bottom panel 13 near the top of the rectangular notch 15. The lower double-sided tape 4 can not only increase the tightness of the bottom structure of the packaging carton, but also improve the anti-theft performance of the bottom when used for express delivery, and at the same time, it can also save the cardboard material at the rectangular notch 15 during production.

[0059] The B panel structure 2 includes a left side panel 21, a front side panel 22 and a right side panel 23 connected in sequence from left to right, the left side panel 21 is connected to an upper left lining panel 211 and a lower left lining panel 212 upward and downward respectively near the right side, and a left upper socket 5 is provided near the left side at the connection between the left side panel 21 and the upper left lining panel 211; the front side panel 22 is connected to an upper front lining panel 221 and a lower front lining panel 222 upward and downward respectively, a tearing structure 14 is provided in the middle of the upper side of the front side panel 22, and the connection between the tearing structure 14 and the front side panel 22 is punched by a dotted line; the tearing structure 14 includes a tearing portion 141 and a hand pinch head 142, the width of the tearing portion 141 is greater than the width of the hand pinch head 142, and the upper side edge of the tearing portion 141 is connected to the side edge of the upper front lining panel 221, and the middle of the lower side edge of the tearing portion 141 is connected to the upper side edge of the hand pinch head 142. The right side plate 23 is connected to the right upper liner 231 and the right lower liner 232 upward and downward near the left side, respectively, and the right upper socket 9 is provided near the right side of the connection between the right side plate 23 and the right upper liner 231; the left and right sides of the front lower liner 222 are both beveled downward, and the left and right sides of the front lower liner 16 and the right and left sides of the front lower liner 17 are formed after the beveling; the left side of the left lower liner 212 and the right side of the right lower liner 232 are also beveled downward, and the left lower liner notch 18 is formed on the left side of the left lower liner 212, and the right lower liner notch 19 is formed on the right side of the right lower liner 232. Thus, while ensuring the bottom strength of the packaging carton, the cardboard materials at the left notch 16, the right notch 17, the left lower liner notch 18 and the right lower liner notch 19 of the front lower liner are further saved.

[0060] When the packaging carton is folded and formed, the top cover 11 is located at the outer top of the packaging carton, the rear side panel 12 is located at the rear side of the packaging carton, and the bottom panel 13 is located at the outer bottom of the packaging carton. The outer sides of the left rear plug-in plate 121 and the right rear plug-in plate 122 are coated with glue and then bonded to the inner sides of the ends of the left side panel 21 and the right side panel 23 respectively, so that the left side panel 21 is located on the left side of the packaging carton, the front side panel 22 is located on the front side of the packaging carton, and the right side panel 23 is located on the right side of the packaging carton; the upper left lining plate 211 and the upper right lining plate 231 are at After being folded inwards 90°, they are respectively located on the left and right sides of the inner top of the packaging carton, and the upper left socket 5 and the upper right socket 9 are respectively close to the left and right sides of the top end of the rear side panel 12; the front upper lining plate 221 is folded inwards 90° and covers the front of the upper left lining plate 211 and the upper right lining plate 231; the top cover 11 is folded forwards 90° and the front part covers the front upper lining plate 221, and the upper double-sided tape 3 is adhered to the upper surface of the front upper lining plate 221, and the left top plug plate 113 and the right top plug plate 114 are respectively inserted into the upper left plug 5 and the upper right plug 9.

[0061] The left lower lining board 212 and the right lower lining board 232 are respectively located on the left and right sides of the inner bottom of the packaging carton after being folded inwards 90°, and the front lower lining board 222 is covered under the front of the left lower lining board 212 and the right lower lining board 232 after being folded inwards 90°; the front of the bottom plate 13 is covered under the front lower lining board 222 after being folded forwards 90°, and the lower double-sided tape 4 is adhered to the lower surface of the front lower lining board 222. The state of each side and top of the packaging carton when folded and formed in this example can be referred to Figure 7 and Figure 8 As shown, the side and top structures of the packaging carton in this example are the same as the side and top structures of the packaging carton in Example 2, and the difference between the two lies in their bottom structures.

[0062] The upper left plug hole 5 and the upper right plug hole 9 are both angular opening structures. Thus, when the left top plug plate 113 and the right top plug plate 114 are inserted into the upper left plug hole 5 and the upper right plug hole 9 respectively, the rear sides of the ends of the left top plug plate 113 and the right top plug plate 114 will first enter the wider opening surface of the rear side of the upper left plug hole 5 and the upper right plug hole 9 respectively, and then the ends of the left top plug plate 113 and the right top plug plate 114 will smoothly enter the entire gap of the upper left plug hole 5 and the upper right plug hole 9 respectively from back to front, so that the insertion is easier.

[0063] At the same time, the entire upper edge of the top cover 11 is in a wavy structure, and a wavy side edge is formed, and after the upper double-sided tape 3 is pasted on the top cover 11, its upper side edge is flush with the upper edge of the wavy side edge. This makes the top cover 11 not fully overlapped, and the wavy edge is made on the premise of saving paper, making the top of the packaging carton beautiful, and with the straight edge release paper of the double-sided tape 3, it is easy to tear open for use.

[0064] When opening the box, people only need to open the handle 142 with their fingers and hold it to pull it upwards, and the connection between the tear structure 14 and the front side plate 22 will break along the dotted line of the punching process, and the tear structure 14 will be separated from the front side plate 22. Then continue to pull upwards, the tearing part 141 of the tear structure 14 drives the front upper lining plate 221 to be forced upwards, so that the two ends of the upper side of the tearing part 141 extend to both sides and break at the dotted line punching process, so that the front upper lining plate 221 can drive the top cover 11 to open from the top of the packaging carton.

[0065] Example 4.

The top cover 11 has an upper double-sided tape 3 bonded to the inner side of the entire edge of the upper side. The design of the upper double-sided tape 3 not only has a bonding effect, but also can increase the anti-theft ability after the top cover 11 of the packaging carton is bonded. The middle of the left and right sides of the top cover 11 are respectively provided with an upper left anti-theft notch 115 and an upper right anti-theft notch 116. The middle of the top cover 11 is provided with a tear strip 112 in the left and right directions. The tear strip 112 is provided with a tear head 1121 near one end of the outer side. The outermost end of the tear head 1121 protrudes outside the upper right anti-theft notch 116 on the right side of the top cover 11, and the width of the tear strip 112 on the outer side of the top cover 11 is greater than the width of the main body of the tear strip 112 on the inner side of the top cover 11. This makes it convenient for people to pinch the tearing head 1121 to pull the box open, and it is also more conducive to the head of the tear strip 112 to bear the force to pull down the entire tear strip 112, helping to quickly open the packaging carton. The right side of the rear side plate 12 is connected to the right rear plug plate 122, and the middle of the left and right sides of the bottom plate 13 are respectively provided with a lower left anti-theft notch 135 and an upper right anti-theft notch 136, and the lower side of the bottom plate 13 is bonded with a lower double-sided tape 4. The lower double-sided tape 4 can not only increase the tightness of the bottom structure of the packaging carton, but also improve the anti-theft performance of the bottom when used for express delivery.

[0069] When the packaging carton is folded and formed, the top cover 11 is located at the outer top of the packaging carton, the rear side panel 12 is located at the rear side of the packaging carton, and the bottom panel 13 is located at the outer bottom of the packaging carton. After the outer sides of the left rear plug-in plate 121 and the right rear plug-in plate 122 are coated with glue, they are respectively bonded to the inner side of the left end of the rear side panel 12 and the inner side of the end of the right side panel 23, so that the left side panel 21 is located on the left side of the packaging carton, the front side panel 22 is located on the front side of the packaging carton, and the right side panel 23 is located on the right side of the packaging carton; the upper left liner 211 and the upper right liner 231 are respectively located on the left and right sides of the inner top of the packaging carton after being folded inwards 90°, and the upper front liner 221 covers the front of the upper left liner 211 and the upper right liner 231 after being folded inwards 90°. After the top cover 11 is folded forward 90°, the front part covers the front upper lining plate 221, and the upper double-sided tape 3 is bonded to the upper surface of the front upper lining plate 221. After the left side panel 21 is folded forward 90°, the left rear plug plate 121 is folded inward again 90°, and the left rear plug plate 121 is attached to the right inner side of the rear side panel 12, and the two anti-theft protrusions 20 punched out at the connection between the left side panel 21 and the left upper lining plate 211 are stuck in the left upper anti-theft notch 115 provided in the middle part of the left side edge of the top cover 11, and the two anti-theft protrusions 20 punched out at the connection between the right side panel 23 and the right upper lining plate 231 are stuck in the right upper anti-theft notch 116 provided in the middle part of the right side edge of the top cover 11, and the tear strip 112 is provided with a tear head 1121 at one end of the outer side thereof, which is stuck in the bayonet 24, and the outer end of the tear head 1121 protrudes out of the bayonet 24.

[0070] The left lower lining plate 212 and the right lower lining plate 232 are respectively located on the left and right sides of the inner bottom of the packaging carton after being folded inwards 90°, and the front lower lining plate 222 is covered under the front of the left lower lining plate 212 and the right lower lining plate 232 after being folded inwards 90°; the front of the bottom plate 13 is covered under the front lower lining plate 222 after being folded forwards 90°, and the lower double-sided tape 4 is adhered to the lower surface of the front lower lining plate 222; after the right side plate 23 is folded forwards 90°, the right rear plug plate 122 is folded inwards 90°, and the right rear plug plate 122 is attached to the inner surface of the right side plate 23. The two anti-theft protrusions 20 punched out at the connection between the left side plate 21 and the left lower lining plate 212 are stuck in the left lower anti-theft notch 135 provided in the middle of the left side edge of the bottom plate 13, and the two anti-theft protrusions 20 punched out at the connection between the right side plate 23 and the right lower lining plate 232 are stuck in the right lower anti-theft notch 136 provided in the middle of the right side edge of the bottom plate 13.

[0071] The entire upper edge of the top cover 11 is in a wavy structure, and a wavy side edge is formed, and after the upper double-sided tape 3 is pasted on the top cover 11, its upper side edge is flush with the upper edge of the wavy side edge. This makes the top cover 11 not fully overlapped, and the wavy edge is made on the premise of saving paper, making the top of the packaging carton beautiful, and with the straight edge release paper of the double-sided tape 3, it is easy to tear and use.

[0072] At the same time, the top cover 11 on the upper side of the wavy structure is also provided with a straight knife cut 117 at the bottom of each concave part, and the straight knife cut 117 extends toward the middle of the top cover 11. The wavy edge plus the straight knife cut not only looks good, but also increases the anti-theft performance of the top of the packaging carton after the double-sided tape 3 is bonded, making it difficult to open, which will destroy the structural integrity of the straight knife cut 117 provided on the top cover 11 of the carton.

[0073] In the above-listed embodiments, the utility model designs the packaging carton to be composed of A panel structure 1 and B panel structure 2, and respectively glues the side connection of A panel structure 1 and B panel structure 2 and then performs corresponding folding processing, and then plugs the folded A panel structure 1 and B panel structure 2 into each other and glues them with double-sided tape, so that the four sides of the formed packaging carton are still single-layer cardboard structures, saving material use, and the top cover 11 and bottom plate 13 of the packaging carton with greater load-bearing strength and greater extrusion pressure are multi-layer cardboard structures. At the same time, double-sided tape is set on the board surfaces of the top cover 11 and bottom plate 13 of the packaging carton, and the sides of the top cover 11 and bottom plate 13 are designed to be plug-in or clip-on connection structures. That is, in combination with the actual situation that the top and bottom are generally subjected to greater forces when packaging goods, a packaging carton with a two-panel structure is designed. By increasing the number and thickness of cardboard layers on the top and bottom surfaces, the strength of the top and bottom surfaces of the packaging carton is improved, which not only saves cardboard materials, but also enhances the strength of the carton, and the folding and unpacking are faster. It not only uses less materials during production, but also has high strength, and can be folded and unpacked quickly. Not only does the top and bottom have sufficient packaging strength, but the top and bottom of the packaging box also have anti-theft functions, which can fully meet the packaging and transportation needs of goods. Thus, the purpose of novel design, reasonable structure, and good application effect is achieved.

[0074] The above is only a preferred implementation of the utility model's anti-theft two-piece packaging carton with less material. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the utility model, which all fall within the protection scope of the utility model.
