Description

Technical Field

[0001] This utility model relates to the field of packaging boxes, and in particular to a glue-free cardboard flip box. Background Technology

[0002] A flip-top box mainly consists of a box body and a flip-top. One side of the flip-top is flexibly connected to the box body. The flip-top can be flipped down onto the box body or flipped up to expose the items inside. However, existing flip-top boxes are generally formed by gluing, which does not meet the environmental requirements of some customers who want to avoid the use of adhesives. Therefore, it is necessary to research a cardboard flip-top box that does not require gluing. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned problems existing in the prior art and provide a glue-free cardboard flip box.

[0004] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0005] A paperboard flip-top box without adhesive includes a flexible insert plate, a front cover, a top cover, a back plate, a bottom plate, and an outer panel connected in sequence. A rear hook plate is flexibly connected to each side of the back plate, and a front hook plate is flexibly connected to each side of the outer panel. The front hook plate and the rear hook plate on the same side of the flip-top box hook each other, so that the bottom plate, back plate, outer panel, front hook plate, and rear hook plate enclose a rectangular box with an open top. A strip-shaped insertion slot is provided in the middle of the junction of the outer panel and the bottom plate. The insert plate is inserted into the strip-shaped insertion slot, so that the top cover covers the opening at the top of the box and the front cover covers the outer panel.

[0006] Preferably, the outer panel is flexibly connected to the inner panel on the side away from the bottom plate, and when the cardboard flip box is in the formed state, the inner panel and the outer panel are tightly fitted back to back.

[0007] Preferably, the inner panel is flexibly connected to the side opposite to the outer panel with a front support plate, and when the cardboard flip box is in the formed state, the front support plate is tightly fitted to the bottom plate.

[0008] Preferably, a set of side blocking mechanisms is flexibly connected to the left and right sides of the base plate. Each set of side blocking mechanisms includes an outer baffle, an upper baffle, an inner baffle, and a side support plate that are flexibly connected in sequence. The side of the outer baffle away from the upper baffle is flexibly connected to the base plate. When the cardboard flip box is in the formed state, the base plate is perpendicular to the outer baffle and the inner baffle, respectively, and the upper baffle, the side support plate, and the base plate are parallel to each other. The front hook plate and the rear hook plate that are hooked to each other are wrapped in the side blocking mechanism.

[0009] Preferably, a side wing plate is flexibly connected to the front and rear sides of the inner baffle. When the cardboard flip box is in the formed state, the side wing plate located on the front side of the inner baffle is sandwiched between the inner baffle and the front hook plate, and the side wing plate located on the rear side of the inner baffle is sandwiched between the inner baffle and the rear hook plate.

[0010] Preferably, a protrusion is provided at the junction of the side support plate and the inner baffle. When the cardboard flip box is in the formed state, the protrusion is inserted between the bottom plate and the front hook plate, and between the bottom plate and the rear hook plate.

[0011] The beneficial effects of this utility model are as follows: The front and rear hook plates are designed to hook together, allowing the bottom plate, back plate, outer panel, front hook plate, and rear hook plate to enclose and form the box body. This achieves box body formation without the use of adhesives, meeting customers' environmental requirements for adhesive-free production. During packaging, simply flip the front and top covers downwards, insert the insert plate into the strip-shaped slot so that the top cover covers the opening at the top of the box body, and the front cover covers the outer panel. To open the box, simply pull the insert plate out of the strip-shaped slot, and then flip the front and top covers upwards. This adhesive-free cardboard flip-top box can be formed without adhesives, facilitating flattening and delivery, and its forming and flipping operations are simple. Attached Figure Description

Detailed Implementation

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] like Figures 1 to 4 As shown, the paperboard flip box 100 includes a flexible insert plate 1, a front cover 2, a top cover 3, a back plate 4, a bottom plate 5, and an outer panel 6 connected in sequence. A rear hook plate 9 is flexibly connected to each side of the back plate 4, and a front hook plate 10 is flexibly connected to each side of the outer panel 6. The front hook plate 10 and the rear hook plate 9 on the same side of the paperboard flip box hook each other, so that the bottom plate 5, the back plate 4, the outer panel 6, the front hook plate 10, and the rear hook plate 9 enclose a box body 200 with a top opening and a rectangular box shape, thus achieving the box body formation without the use of adhesives, thereby meeting the customer's environmental protection requirements for the absence of adhesives.

[0020] A strip-shaped slot 11 is provided at the middle of the junction of the outer panel 6 and the bottom plate 5. The insert plate 1 is inserted into the strip-shaped slot 11, so that the top cover 3 covers the opening at the top of the box 200 and the front cover 2 covers the outer panel 6.

[0021] The outer panel 6 is flexibly connected to the inner panel 7 on the side away from the bottom plate. When the cardboard flip box 100 is in the formed state, the inner panel 7 and the outer panel 6 are tightly fitted back-to-back. The inner panel 7 and the opposite side of the outer panel 6 are flexibly connected to the front support plate 8. When the cardboard flip box 100 is in the formed state, the front support plate 8 is tightly fitted to the bottom plate 5. The inner panel 7, the front support plate 8, and the outer panel 6 work together to increase the rigidity of the front of the box body 200, which helps the front of the box body 200 maintain a good shape during use.

[0022] A set of side blocking mechanisms 300 are flexibly connected to the left and right sides of the base plate 5. Each set of side blocking mechanisms 300 includes an outer baffle 12, an upper baffle 13, an inner baffle 14, and a side support plate 15, which are flexibly connected in sequence. The side of the outer baffle 12 away from the upper baffle 13 is flexibly connected to the base plate 5. When the cardboard flip box 100 is in the formed state, the base plate 5 is perpendicular to the outer baffle 12 and the inner baffle 14, respectively, while the upper baffle 13, the side support plate 15, and the base plate 5 are parallel to each other. The front hook plate 10 and the rear hook plate 9, which are hooked to each other, are wrapped in the side blocking mechanism 300.

[0023] A side wing plate 16 is flexibly connected to the front and rear sides of the inner baffle 14. When the cardboard flip box 100 is in the formed state, the side wing plate 16 located in front of the inner baffle 14 is sandwiched between the inner baffle 14 and the front hook plate 10, and the side wing plate 16 located behind the inner baffle 14 is sandwiched between the inner baffle 14 and the rear hook plate 9.

[0024] The side guard mechanism 300 is designed to improve the rigidity of the left and right sides of the box body 200, which helps the left and right sides of the box body 200 maintain a good shape during use. On the other hand, it increases the width of the top of the left and right sides of the box body, increases the overlap area between the top cover and the left and right sides of the box body, and reduces the risk of light leakage from the left and right sides of the glueless cardboard flip box.

[0025] A protrusion 17, which is integrally connected to the side support plate 15, is provided at the junction of the side support plate 15 and the inner baffle plate 14. When the cardboard flip box 100 is in the formed state, the protrusion 17 is inserted between the bottom plate 5 and the front hook plate 10, and between the bottom plate 5 and the rear hook plate 9. The protrusion 17 is used to prevent the side baffle mechanism from becoming loose during use, which helps to ensure that the side baffle mechanism maintains its formed state during use.
