Description

Technical Field

[0001] The utility model relates to the technical field of packaging paper, in particular to a foldable packaging paper tray. Background Art

[0002] When transporting fragile bottles such as wine bottles, it is necessary to support and protect the fragile bottles by using a paper shell bottom plate in combination with a foam bottom tray; when the fragile bottle is placed on the foam bottom tray, the bottle body is limited so that it can be protected during transportation. However, foam is generally made of polystyrene (PS) material, which is difficult to be degraded by microorganisms and will continue to exist in the natural environment. The garbage disposal of foam mainly depends on landfill. During the landfill process, the foam box will be buried underground with other garbage and exist underground for a long time, causing pollution to the environment. Therefore, the prior art designs wine bottle paper trays, such as the patent with publication number CN207107201U, which discloses a new type of wine bottle bottom tray, but the main structure used is a split structure, including a paper box constituting the bottom tray, and a supporting structure of the bottom tray; it cannot achieve integrated folding molding; it needs to be cut separately during production line processing, and the operator needs to match the bottom tray structure and the supporting structure of the bottom tray one by one during assembly, and the assembly steps are cumbersome; it is not conducive to factory assembly line production. Utility Model Content

[0003] In view of the deficiencies in the prior art, the technical problem solved by the utility model is to provide a foldable packaging paper tray, which solves the problem that the existing paper trays for fragile bottles are mainly split paper trays, the assembly steps are cumbersome, and are not conducive to factory assembly line production.

[0004] The foldable packaging paper tray of claim 1, wherein the two bottom side panels are symmetrically arranged on both longitudinal sides of the support plate, and the two support side panels are symmetrically arranged on both transverse sides of the support plate. A first fold is provided at the connection between the bottom side panel and the support plate, and a second fold is provided along the longitudinal direction of the bottom side panel near the first fold. A third fold is provided at the connection between the support side panel and the support plate, and a support strip is provided at the longitudinal side edge of the support side panel and the support strip is transversely arranged, and a fourth fold is provided at the connection between the support strip and the longitudinal side edge; the bottom side panel can be flipped to the bottom of the support plate along the first fold and the second fold, and the support side panel can be flipped to the side of the support plate along the third side panel, and the support plate and the flipped bottom side panel and support side panel together constitute a support portion, and the support strip abuts against the bottom of the support portion after being flipped along the fourth fold.

[0005] The beneficial effects of this solution are as follows: by adopting the foldable packaging paper tray of this solution, a base tray and a supporting structure at the bottom of the base tray can be formed by folding the same paperboard, which is easier to assemble than a split structure, does not require separate cutting of different components, and is more suitable for factory assembly line production; the bottom side panels and supporting side panels are folded to form a supporting portion with the supporting plate, and a fragile bottle is placed in the supporting portion through the opening of the supporting plate, and the supporting portion has a buffering effect on the bottle body; secondly, the bottom of the supporting portion is supported by the folded support strips, and a buffering effect is played on the bottom of the bottle body.

[0006] Furthermore, the support bar is provided with a card interface, and a plurality of support bars are provided; the plurality of support bars are turned over along the fourth fold and connected through the card interface. The support bars are connected through the card interface, so that the support side panels are limited in position by the support bars connected together, and the bottom is supported and limited in position at the same time, so as to ensure that the bottom bracket structure is stable after folding, and is easy to connect and disassemble.

[0007] Furthermore, four support bars are symmetrically arranged along the center line of the support plate, and the card interface is arranged at the end of the support bar. The card interface of the support bar located on the same support side plate has opposite opening directions, and the card interface of the support bar located on the same side of different support plates has the same opening direction. By arranging four support bars, the four support bars are connected together through the card interface to form an X shape, thereby stably supporting the bottom of the support part and playing the role of limiting the bottom side plate after folding.

[0008] Furthermore, the support bar is divided into a connection end and a support section through the card interface, the support section is located between the card interface and the support side plate, and the height of the connection end is less than the height of the support section. The connection end is set lower than the support section, leaving enough space for multiple support bars to be connected to the same card interface, so that multiple support bars can be connected together through the card interface.

[0009] Furthermore, the opening of the support plate is a polygonal opening, and a plurality of cutouts are sequentially arranged along the extension lines of the two diagonals of the polygonal opening, a trapezoidal support plate is formed between the two cutouts, and a fifth fold is arranged between the ends of the four cutouts, and the trapezoidal support plate can be turned down along the fifth fold to the inside of the support portion. The plurality of fifth folds form a larger polygonal opening, and the trapezoidal support plate turned down has a tendency to turn up, thereby contacting the bottle body placed in the polygonal opening, thereby playing a supporting role.

[0010] Furthermore, a first circular hole is formed on the support plate at the end of the cutout. By processing the first circular hole at the end of the cutout, the trapezoidal portion is conveniently folded along the fifth fold line. Due to the first circular hole, two adjacent trapezoidal support plates are appropriately left with space when folding, and interference will not occur at the end of the cutout, so that it is not easy to break the edge at the end, thereby improving the product yield rate.

[0011] Furthermore, a second circular hole is formed on the fifth fold of the support plate, and the diameter of the second circular hole is larger than that of the first circular hole. The second circular hole is provided to facilitate consumers to take the wine out of the bottom tray.

[0012] Furthermore, the polygonal opening of the support plate is a 4-8 polygon. Most glass bottles are mainly square and round, and the 4-8 polygon can meet the packaging needs of mainstream glass bottles.

[0013] Furthermore, the aperture of the first circular hole is 2-6 mm, which can prevent creases and bursting edges after cutting and facilitate processing.

[0014] Furthermore, the direct length from the end of the bottom plate to the second fold is equal to the length of the support plate. Therefore, after folding, the two bottom side plates will overlap at the bottom to form the support bottom plate, thereby improving the stability of the bottom structure.

[0020] Embodiment 1 is basically as attached Figure 1-3 As shown:

[0021] A foldable packaging paper tray comprises a support plate with an opening, two bottom side panels 2 and two support side panels 3, the two bottom side panels 2 are symmetrically arranged on both sides of the support plate in the longitudinal direction, the two support side panels 3 are symmetrically arranged on both sides of the support plate in the transverse direction, a first fold 21 is arranged at the connection between the bottom side panel 2 and the support plate, a second fold 22 is arranged at the bottom side panel 2 near the first fold 21 along the longitudinal direction, a third fold 31 is arranged at the connection between the support side panel 3 and the support plate, a support strip 32 is arranged at the longitudinal side edge of the support side panel 3, and the support strip 32 is arranged along the transverse direction. A fourth fold 33 is provided at the connection between the support bar 32 and the longitudinal side edge; the distance between the support bar 32 and the bottom side panel 2 is equal to the distance between the first fold 21 and the second fold 22 plus the thickness of the bottom side panel 2; the bottom side panel 2 can be flipped along the first fold 21 and the second fold 22 to the bottom of the support plate, and the support side panel 3 can be flipped along the third side panel to the side of the support plate, and the support plate and the flipped bottom side panel 2 and support side panel 3 together constitute the support part 1, and the support bar 32 is flipped along the fourth fold 33 and abuts against the bottom of the support part 1.

[0022] The opening of the support plate is a polygonal opening, and a plurality of cutouts 11 are sequentially arranged along the extension lines of the two diagonals of the polygonal opening, a trapezoidal support plate 14 is formed between the two cutouts 11, and a fifth fold 15 is arranged between the ends of the four cutouts 11, and the trapezoidal support plate 14 can be turned down along the fifth fold 15 to the inside of the support part 1, a first circular hole 12 is opened on the support plate at the end of the cutout 11, and a second circular hole 13 is opened on the fifth fold 15 of the support plate, and the aperture of the second circular hole 13 is larger than the first circular hole 12, the aperture of the first circular hole 12 is 5mm, and the aperture of the second circular hole 13 is 10-25mm, and the preferred aperture in this embodiment is 20mm. The width of a finger is generally about 13mm, and the circular hole with an aperture in this range is convenient for the finger to be inserted into the circular hole to take out the bottle.

[0023] The plurality of fifth folds 15 form a larger polygonal opening, through the downwardly turned trapezoidal support plate 14, because the trapezoidal support plate 14 has a tendency to turn upward, it will conflict with the bottle body placed in the polygonal opening, and then play a supporting role. The polygonal opening of the support plate is a 4-8-gon, and in this embodiment it is a quadrilateral. Most glass bottles are mainly square and round, and the use of a 4-8-gon can meet the packaging needs of mainstream glass bottles.

[0024] The direct length from the end of the bottom plate to the second fold 22 is equal to the length of the support plate, so after folding, the two bottom side plates 2 will overlap at the bottom to form the bottom plate of the support part 1, thereby improving the stability of the bottom structure.

[0025] Four support bars 32 are symmetrically arranged along the center line of the support plate, and the card interface 321 is arranged at the end of the support bar 32. The opening directions of the card interface 321 of the support bar 32 located on the same support side plate 3 are opposite, and the opening directions of the card interface 321 of the support bar 32 located on the same side of different support plates are the same. By setting four support bars 32, the four support bars 32 are snapped together through the card interface 321 to form an X shape, thereby stably supporting the bottom of the support part 1 and playing a role in limiting the bottom side plate 2 after folding. The support bar 32 is divided into a connecting end 323 and a supporting section 322 through the card interface 321. The supporting section 322 is located between the card interface 321 and the support side plate 3, and the height of the connecting end 323 is less than the height of the supporting section 322. The connecting end 323 is set to be lower than the supporting section 322, leaving enough space for multiple support bars 32 to be snapped together at the same card interface 321, so that multiple support bars 32 can be snapped together through the card interface 321.
