Description

Technical Field

[0001] The utility model belongs to the technical field of packaging boxes, and particularly relates to a cake box cover made entirely of paper. Background Art

[0002] Cake boxes are used to hold cakes and need to be stable and easy to take out. Cake boxes are usually composed of three parts: a base, a box tube that fits on the base, and a lid that covers the box tube.

[0003] With the growing awareness of environmentally friendly consumption, all-paper packaging boxes are becoming a trend. Consequently, all-paper cake boxes have emerged in the prior art. However, current all-paper cake boxes generally suffer from two drawbacks: first, the all-paper base has poor load-bearing capacity and is not stable enough to withstand the weight of the cake, easily collapsing. Second, because the box sleeve fits over the base, the base sinks completely into the tube, making it difficult to remove the box from the base when opening the cake box, affecting the consumer experience while eating the cake. Utility Model Content

[0004] The technical problem to be solved by the present invention is to provide a cake box made of all paper material with good bottom support and good load-bearing capacity, so as to overcome the defects of the prior art.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] Disclosed is a cake box made entirely of paper, wherein the box cover, box tube, and base are all made of paper material. The lower opening of the box tube is sleeved on the base, and the box cover covers the upper opening of the box tube. The base comprises a separate upper bottom plate and a lower bottom plate, a support member is provided between the upper and lower bottom plates, and outwardly protruding baffles are respectively provided on both sides of the base. The baffles stop the edge of the lower opening of the box tube to prevent the base from being completely sunken into the box tube.

[0007] By adopting the above technology, the utility model improves the load-bearing capacity of the base tray by arranging a support member at the bottom of the base tray, so that the base tray is not easy to collapse when a cake is placed on it; the two sides of the base tray are provided with outwardly protruding blocking pieces that can stop the lower end opening edge of the box tube to prevent the base tray from being completely sunken into the box tube, so that when the cake box is opened, the box tube can be easily removed from the base tray.

[0008] Therefore, compared with the prior art, the utility model has the advantages that the bottom support has a strong load-bearing capacity, the bottom support will not sink into the box tube, and people are easy to open the cake box. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will be combined with the accompanying drawings to clearly and completely describe the technical solution of the utility model. Obviously, the embodiments described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the utility model patent.

[0019] The terms "upper", "lower", "left", "right", etc. used in this specification are only for the convenience of description and are not intended to limit the scope of implementation of the present invention. Changes or adjustments to their relative relationships, without substantially changing the technical content, should also be regarded as the scope of implementation of the present invention.

[0020] See also Figure 1 and Figure 2 As shown in the figure, the cake box of the present invention is made of all paper material, which is a cube structure and is composed of three parts: a box cover 10, a box tube 20 and a base 30. The cake box of the present invention is made of all paper material, that is, the box cover 10, the box tube 20 and the base 30 are all made of corrugated paper or cardboard.

[0021] Combine Figure 4C and Figure 4DAs shown, the base 30 is provided with four support members 33 to enhance the supporting strength of the base 30 and improve the stability of the base's load-bearing capacity. The base 30 is folded on both sides to form outwardly protruding stoppers 40. When the lower opening of the box tube 20 is placed on the base 30, these stoppers stop the lower opening edge of the box tube 20 to prevent the base 30 from completely sinking into the box tube 20. This makes it easy to remove the box tube 20 from the base when the cake box is opened. The lid 10 is folded downward to form a peripheral edge 11, which is used to fit over the top of the box tube during packaging, enhancing the stability of the cake box packaging.

[0022] like Figures 3A to 3D and combined Figure 6 As shown, the box barrel 20 is formed by four side panels 21 connected sequentially from left to right. Each of the four side panels 21 has a box barrel thickening plate 211 on its upper and lower sides. After being coated with glue, the box barrel thickening plates 211 are folded inward and adhered to the inner surfaces of the side panels 21, increasing the thickness of the box barrel 20 and improving its strength. After the box barrel 20 is folded along the vertical crease lines 22 between the side panels, an adhesive plate 212 extends from the outer side of the leftmost side panel 21. After being glued, it adheres to the protruding edge 21a of the rightmost side panel 21, and after being stretched from the inside, the box barrel is finally formed.

[0023] like Figures 4A to 4D Shown and combined Figure 8As shown, the base 30 is composed of an upper base plate 31 and a lower base plate 32. There is a connecting sealing plate 36 between the upper base plate 31 and the lower base plate 32. The connecting sealing plate 36 is connected to the lower base plate 32 through a first crease line 34, and is connected to the upper base plate 31 through a second crease line 35. There are edge thickening plates 322 on the left and right sides of the lower base plate 32, which are folded inward along the thickening crease line 321 after gluing and adhered to the edge of the lower base plate 32 to form a thickened baffle 40. The lower base plate 32 has four support members 33 distributed in an array in the middle area. Each support member is cut through the lower base plate so that three side edges (i.e., the three first side edges 33a) are separated from the lower base plate 32, and only one side edge (i.e., the second side edge 33b) is connected to the main body of the lower base plate. The support member 33 is composed of a support portion 332 connected to the main body of the lower base plate and an adhesive portion 331 connected to the support portion 332. A support crease line 333 is defined between the adhesive portion 331 and the support portion 332. After the adhesive portion 331 is glued, it is folded along the first crease line 34 on the lower base plate and then adhered to the upper base plate 31. An upper sealing plate 31c extends from the upper side of the upper base plate 31, and a side sealing plate 31a extends from the left and right sides. The side sealing plates 31a are connected to the upper base plate 31 by a sealing plate crease line 311. The side sealing plates 31a are folded along the sealing plate crease line 311 so that the side sealing plates 31a are perpendicular to the upper base surface 31. There is an adhesive plate 212 on the outside of the upper sealing plate 31c. After the adhesive plate is folded along the transverse crease line 312, it is adhered to the lower edge 32a of the lower base surface 32 with glue. After the upper base plate 31 is folded along the second crease line 35, the upper base plate 31 and the lower base plate 32 are then stretched apart, one above the other, to separate the upper base plate 31 from the lower base plate 32. During the stretching process, the upper base plate 31 automatically pulls the support member 33, causing the support portion 332 to stand upright to support between the upper base plate 31 and the lower base plate 32, thereby increasing the supporting force of the base plate 30. This structure enhances the load-bearing capacity of the base plate 30 and solves the problem of weak load-bearing capacity of the full-paper base plate. The crease lines 311 of the side sealing plates 31a on the upper base plate 31 and its left and right sides are offset inward compared to the thickening crease line 321 of the lower base plate 32. In this way, after the upper base plate 31 is folded, two outwardly protruding baffles 40 are formed on the left and right sides of the base plate 30. There is a fold line 313 between the inserting plates 31b extending outward from the left and right closing plates 31a. The inserting plates 31b are folded along the fold line 313 and inserted into the inner surface of the lower bottom plate 32. In this way, the openings on both sides of the base 30 are sealed, and finally a three-dimensional structure is formed.

[0024] like Figures 5A to 5C Combine Figure 7As shown, the box lid 10 is composed of a cover plate 10a and a peripheral edge 11 folded downward from the cover plate. Extending outward from the outer sides of the left and right peripheral edges 11 are adhesive thickening plates 114. After being coated with glue, they are folded inward along the first vertical crease line 12 and adhered to the surfaces of the left and right peripheral edges 11, increasing the thickness of the peripheral edges 11 and thus increasing its strength. The peripheral edges 11 of the box lid 10 are folded along the first crease line 13 of the box lid to be perpendicular to the cover plate 10a. Extending outward from the outer sides of the upper and lower peripheral edges 11 of the box lid 10 are non-adhesive thickening plates 115, each with an insert 111 at its left and right ends. The adhesive thickening plates 114 have notches 112 at both ends. After the non-adhesive thickening plate 115 is folded and attached to the upper and lower edges 11 along the second crease line 14 of the box cover, the ears 111 are stuck on the inner surfaces of the left and right edges 11 and positioned in the notches 112. After the edges 11 are folded perpendicular to the cover plate 10a, the corner connecting pieces 113 between the edges 11 are folded into the interior of the box cover 10 to form the box cover 10.

[0025] When packaging a cake, the cake is placed on the base 30 , the lower opening of the box tube 20 is sleeved on the base 30 , and the box cover 10 covers the upper opening of the box tube 20 , and the three are assembled to form a fully paper-packaged cake box.

[0026] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
