Description

Technical Field

[0001] The utility model relates to the technical field of express packaging boxes, in particular to a tape-free express packaging box. Background Art

[0002] Corrugated cardboard boxes are widely used for product packaging in the express delivery industry. They are used in large quantities and can be recycled and reused.

[0003] During the use of existing packaging boxes, the upper side of the box is opened. After the product is placed in, the upper side is sealed with a top plate, and finally the top plate is firmly glued with tape. However, after the box reaches the customer's hands, the tape on the top plate is torn off and discarded. The tape is difficult to recycle, causing pollution and waste.

[0004] A large number of tape-free packaging boxes have also appeared in the postal industry. For example, the patent document with authorization announcement number CN210708331U discloses a tape-free packaging box for express delivery. The top plate is sealed by plugging the cover. Although it uses a plug and a clamp to cooperate with each other for connection and sealing, in this plug-in connection, the plug and the socket are directly opposite each other up and down, and the connection is still unstable and easy to fall off. Moreover, the more firmly the plug is plugged in, the easier it is to be damaged and torn during disassembly, which is not conducive to the reuse of the packaging box.

[0005] In the prior art, the plug and the socket are vertically opposite to each other, which is unstable and has the problem of being easily fallen off, which needs to be solved. Utility Model Content

[0006] The technical problem to be solved by the present invention is to provide a tape-free express packaging box in response to the above-mentioned technical deficiencies, which solves the problem in the prior art that the plug and the socket are directly opposite each other, which is unstable and easy to fall off.

[0007] The technical solution adopted by the utility model is to provide a tape-free express packaging box, including a box body, the side of which includes four side panels connected in sequence along a ring, each of the side panels is provided with a top panel at the upper end, the four top panels are composed of two first upper covers and two second upper covers arranged at intervals, the first upper cover is located on the upper side of the second upper cover, the first upper cover and the second upper cover are sealed with a sealing plate, the second upper cover has a plug hole on one side close to the side panel, the plug hole is "U"-shaped, and plugs for passing through the plug hole are provided at both ends of the sealing plate; it is characterized in that the plug includes a trapezoidal locking portion, and after the plug passes through the locking portion, the locking portion abuts against the lower end of the second upper cover; the upper end of one of the side panels connected to the second upper cover has two side wing through holes and a positioning through hole, the two side wing through holes are respectively opposite to the two sides of the locking portion, the positioning through hole is opposite to the lower side of the locking portion, and the positioning through hole is located between the two side wing through holes; it also includes:

[0008] A first blocking plate is movably provided in each of the side wing through holes, for blocking or opening the side wing through holes;

[0009] A second blocking plate is movably provided in the positioning through hole and is used for blocking or opening the positioning through hole.

[0010] To further optimize the technical solution, the side panels are formed by breaking holes to form the first blocking panel and the second blocking panel, and the breaking hole positions are the wing through-hole positions or the positioning through-hole positions.

[0011] Further optimization of this technical solution also includes:

[0012] The mounting plate is arranged on the outer side of the upper portion of the side plate having the side wing through holes, and the first blocking plate and the second blocking plate are both movably arranged on the mounting plate.

[0013] To further optimize the technical solution, the mounting plate is formed by breaking and punching holes to form the first blocking plate and the second blocking plate.

[0014] To further optimize the technical solution, the first blocking plate and the second blocking plate are both hinged to the mounting plate.

[0015] Further optimization of this technical solution also includes:

[0016] The inner plate is arranged on the inner side of the upper part of the side plate and is arranged opposite to the mounting plate. The inner plate and the mounting plate are plug-connected.

[0017] To further optimize the technical solution, the upper part of each side panel connected to the second upper cover has two side wing through holes and one positioning through hole, a first blocking plate is movably provided in each side wing through hole, and a second blocking plate is movably provided in each positioning through hole.

[0018] To further optimize the technical solution, the sealing plate is provided with a plurality of connectors, and the connectors are plug-connected to the first upper cover and / or the second upper cover.

[0019] To further optimize the technical solution, the second upper cover is provided with an upper pressure edge, and the upper pressure edge abuts against the upper side of the first upper cover.

[0020] The beneficial effects of the present invention are:

[0021] 1. The plug is bent downward relative to the sealing plate. The locking portion of the plug is a trapezoidal structure, but there are no bending lines on both sides of the locking portion in the horizontal direction. By squeezing the locking portion inward to make it close to a "U" shape, it passes through the jack and enters under the second upper cover. Then, the locking portion naturally returns to a nearly flat state. The locking portion abuts against the lower end of the second upper cover and is not completely opposite to the jack, avoiding loosening and falling off when the plug slides up and down when it is exactly opposite, thereby improving the connection stability.

[0022] 2. The connection is more stable and is not easily torn or damaged when removing the sealing plate. Through the two movable first and second sealing plates, you can use your fingers to enter the box from the outside through the side holes and the positioning holes, squeeze the locking part inward to form a "U" shape, and then pass it out from the jack.

[0023] 3. The first blocking plate and the second blocking plate block the side wing through holes and the positioning through holes to keep the box in a relatively closed state. BRIEF DESCRIPTION OF THE DRAWINGS

Furthermore, to simplify the drawings and facilitate understanding, in some figures, only one of the components with the same structure or function is schematically shown or labeled. In this document, "one" not only means "only one" but also "more than one," and "several" includes "two" and "more than two."

[0035] It should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0036] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0037] like Figure 1-8As shown, a tape-free express packaging box includes a box body 1, the side of the box body 1 includes four side panels 101 connected in sequence along a ring, and a top panel is provided on the upper end of each side panel 101. The four top panels are composed of two first upper covers 102 and two second upper covers 103 arranged at intervals. The first upper cover 102 is located on the upper side of the second upper cover 103. The first upper cover 102 and the second upper cover 103 are sealed with a sealing plate 2. The second upper cover 103 has a socket 1031 on the side close to the side panel 101. The socket 1031 is "U"-shaped. Plugs 201 for passing through the socket 1031 are provided at both ends of the sealing plate 2; the plug 201 includes a trapezoidal locking portion 2011. After the plug 201 passes through the socket 1031, the locking portion The part 2011 abuts against the lower end of the second upper cover 103; one of the side panels 101 connected to the second upper cover 103 has two side wing through holes 1011 and a positioning through hole 1012 on the upper part, and the two side wing through holes 1011 are respectively opposite to the two sides of the locking part 2011, and the positioning through hole 1012 is opposite to the lower side of the locking part 2011, and the positioning through hole 1012 is located between the two side wing through holes 1011; it also includes: a first blocking plate 3, a first blocking plate 3 is movably provided in each side wing through hole 1011, for blocking or opening the side wing through hole 1011; a second blocking plate 4, a second blocking plate 4 is movably provided in the positioning through hole 1012, for blocking or opening the positioning through hole 1012. The upper part of each side panel 101 connected to the second upper cover 103 has two side wing through holes 1011 and a positioning through hole 1012, and a first blocking plate 3 is movably provided in each side wing through hole 1011, and a second blocking plate 4 is movably provided in each positioning through hole 1012.

[0038] When in use, after the product enters the box body 1, the second upper cover 103 is closed first, and then the first upper cover 102 is covered on the second upper cover 103. The fingers squeeze the protruding two sides of the engaging clamping portion 2011 inward to make it close to a "U" shape, pass through the socket 1031 of the second upper cover 103, and enter the interior of the box body 1. The clamping portion 2011 is a flat structure without a bending line, etc., and the pressure of the fingers is lost. The clamping portion 2011 naturally unfolds (even if it is not flattened, it can be used), and the protruding two sides are moved away from the bottom of the two side channels of the "U"-shaped socket 1031, changing the situation of being directly opposite (or very close) in the prior art. If there is more deviation, it is not easy to shake or fall off. The plugs 201 on both sides pass through the two sockets 1031 respectively, and the sealing plate 2 covers the upper side of the first upper cover 102 to complete the sealing of the box body 1.

[0039] When the sealing plate 2 needs to be removed, the thumb, index finger and middle finger can be used to control the locking portion 2011 (the three fingers are in a similar posture to holding a wine glass, with the thumb and index finger on both sides and the middle finger bent in the middle). The thumb and index finger press the two first blocking plates 3 to open the two side wing through holes 1011 after moving. The two side wing through holes 1011 are respectively opposite to the two sides of the locking portion 2011 in the horizontal direction, that is, the thumb and index finger can be used to squeeze the locking portion 2011 inward from both sides. 1. At the same time, the middle finger presses the second blocking plate 4 to move it and open the positioning through hole 1012. The positioning through hole 1012 can be opposite to the lower part of the locking part 2011 or below the locking part 2011. The middle finger can touch the middle part of the lower side of the locking part 2011. The middle finger can limit the middle part of the locking part 2011. At this time, the thumb and index finger can squeeze the two sides of the locking part 2011 inward to make the locking part 2011 close to a "U" shape, and then take it out of the insertion hole 1031.

[0040] One of the side panels 101 is provided with a flank through hole 1011 and a positioning through hole 1012. When the sealing plate 2 is removed, the box body 1 can be opened by opening one side. Of course, the two side panels 101 connected to the second upper cover 103 can also be provided with the same arrangement.

[0041] Since the locking portion 2011 is not completely opposite to the insertion hole 1031 after insertion, the insertion hole 1031 can be a slit structure, and the locking portion 2011 can be deformed and opened when passing through, or it can be loosely matched with the locking portion 2011 to facilitate the locking portion 2011 to freely pass through in a "U" shape, thereby reducing tearing damage caused by obstruction of movement of the locking portion 2011.

[0042] The structure of the bottom and side parts of the box body 1 can refer to the existing technology.

[0043] Furthermore, the side plate 101 is formed into a first blocking plate 3 and a second blocking plate 4 by means of broken line punching, and the broken line punching positions are the positions of the side wing through holes 1011 or the positioning through holes 1012 .

[0044] When in use, the first sealing plate 3 and the second sealing plate 4 can be processed on the side panel 101 by means of breaking and punching. When used for the first time, the first sealing plate 3 and the second sealing plate 4 are still an integrated structure with the side panel 101. When removing the sealing plate 2, the first sealing plate 3 and the second sealing plate 4 are pressed to disconnect them from the side panel 101 at the breaking point. After opening, the side wing through holes 1011 and the positioning through holes 1012 are naturally exposed on the side panel 101.

[0045] By using the broken line punching method, it is possible to determine whether the package has been unpacked during the first use. The broken line punching can be set along the entire angle of the ring, or it can be set to be partially broken. The first blocking plate 3 and the second blocking plate 4 are partially integrated with the side plate 101. After the broken line is broken, the first blocking plate 3 and the second blocking plate 4 can rotate to open the side wing through hole 1011 and the positioning through hole 1012.

[0046] Of course, it is also possible to open a hole in the side panel 101 and then insert the first blocking plate 3 and the second blocking plate 4 for use.

[0047] Furthermore, it also includes: a mounting plate 5, which is arranged on the upper outer side of the side plate 101 with the side wing through holes 1011, and the first blocking plate 3 and the second blocking plate 4 are both movably arranged on the mounting plate 5.

[0048] During use, the first and second blocking plates 3 and 4 can be directly mounted on the side panels 101 as described above, or mounted on the mounting plate 5. Mounting plate 5 is mounted on the side panels 101, and the first and second blocking plates 3 and 4 are positioned opposite the wing through-holes 1011 and the positioning through-holes 1012, respectively. The mounting plate 5 facilitates partial replacement, extending the service life of the first and second blocking plates 3 and 4, and facilitating more recycling of the box body 1. The mounting plate 5 can be mounted on the inside of the side panels 101 to reduce bulging, or it can be mounted on the outside of the side panels 101 to better block the wing through-holes 1011 and the positioning through-holes 1012.

[0049] Furthermore, the mounting plate 5 is formed into a first blocking plate 3 and a second blocking plate 4 by breaking and punching.

[0050] During use, the mounting plate 5 can also be punched to form the first and second blocking plates 3 and 4, respectively. The punching method can refer to the above example. The mounting plate 5 can be made of the same cardboard material as the box body 1, or can be made of common materials such as plastic, and can be recycled along with the box body 1.

[0051] Furthermore, the first blocking plate 3 and the second blocking plate 4 are both hinged to the mounting plate 5 .

[0052] When in use, the first blocking plate 3 and the second blocking plate 4 can be hinged to the mounting plate 5 via a rotating shaft structure, or can be integrally connected to the mounting plate 5 at a local position in a bendable manner.

[0053] Furthermore, it also includes: an inner plate 6, which is arranged on the inner side of the upper part of the side plate 101 and is arranged opposite to the mounting plate 5, and the inner plate 6 and the mounting plate 5 are plug-connected.

[0054] During use, the inner panel 6 and the mounting plate 5 sandwich the side panel 101 in between for positioning. Insertion posts 601 can be provided on the inner panel 6. Insertion posts 601 pass through the side panel 101 and connect to the mounting plate 5, making installation convenient and stable, and allowing for non-destructive replacement. A clearance window is provided on the inner panel 6 to facilitate the movement and opening of the first and second blocking panels 3 and 4.

[0055] Furthermore, the sealing plate 2 has a plurality of connectors 202 , which are plug-connected to the first upper cover 102 and / or the second upper cover 103 .

[0056] During use, a connector 202 can be provided, as described in prior art, to further enhance connection stability. The connector 202 can be a trapezoidal structure, plugging into the corresponding through-holes in the first upper cover 102 and / or the second upper cover 103. Multiple connectors 202 can be provided at intervals along the annular side of the sealing plate 2.

[0057] Furthermore, the second upper cover 103 has an upper pressing edge 1032 , which abuts against the upper side of the first upper cover 102 .

[0058] When in use, an upper pressure edge 1032 can be set on the side of the second upper cover 103 away from the side plate 101. By breaking the line, the upper pressure edge 1032 can be bent upward and pressed against the upper end of the first upper cover 102. Two upper pressure edges 1032 can be symmetrically set in the middle of one side of each second upper cover 103, which press the first upper covers 102 on both sides respectively, thereby strengthening the connection between the second upper cover 103 and the second upper cover 103.
