Description

Technical Field

[0001] The utility model relates to the field of packaging boxes, in particular to a cake packaging box with good sealing performance. Background Art

[0002] Cake boxes are used for cake packaging to protect cakes and facilitate consumers to carry them.

[0003] In the utility model patent with authorization announcement number CN201857013U, a cake packaging box is disclosed, including a box bottom for holding the cake, a tubular box body and a box lid. A slitting device is fixed to one end of the box body, and the slitting device is at a distance from the top of the cake; the slitting device is composed of multiple intersecting slicing slices, all of which intersect on the same straight line, and the intersection line of the slicing slices coincides with the central axis of the box body. The slicing slices divide the box body into multiple uniform areas, and the two ends of the slicing slices are respectively fixed to the box body.

[0004] However, due to the material of the existing cake box, the transparent enclosure in the middle is easy to collapse, thereby affecting the overall sealing, and the heat preservation effect is poor, and the cake is easy to melt. Therefore, it needs to be improved. Utility Model Content

[0005] The purpose of the utility model is to provide a cake packaging box with good sealing performance, which solves the problem that the transparent enclosure in the middle of the existing cake box is easily collapsed due to material reasons, thereby affecting the overall sealing performance, and at the same time solves the problem that the heat preservation effect is poor and the cake is easily melted.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a cake packaging box with good sealing performance, comprising a base, a transparent enclosure placed on the upper end of the base, a support bar slidingly connected to the inside of the corner of the transparent enclosure, the support bar is plugged into the base, the top of the transparent enclosure is slidingly connected to the box cover, the side of the box cover is fixedly connected to a locking bar, the locking bar is in contact with the base, a locking block is fixedly connected to the locking bar, and the locking block is clamped with the base.

[0007] Preferably, a clamping block is fixedly connected to the upper end of the locking block, and the clamping block is clamped with the base. By setting the clamping block, the strength of the combination of the locking block and the base can be increased.

[0008] Preferably, an ice bag is placed inside the base, which can keep the food in the packaging box fresh.

[0009] Preferably, a buckle cover is placed on the upper end of the base, and a through hole is opened inside the buckle cover. The through hole facilitates air to enter the bottom of the buckle cover.

[0010] Preferably, a positioning bead is fixedly connected to the bottom of the buckle cover, and the positioning bead is engaged with the base. The arrangement of the positioning bead provides a positioning and locking effect for the buckle cover.

[0011] Preferably, a slot is provided at the upper end of the base, and the support bar is inserted into the slot. The arrangement of the slot facilitates the positioning of the support bar on the base.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] 1. The utility model inserts a support bar into each of the four corners of the transparent enclosure of the packaging box. In this way, when the transparent enclosure is placed on the base, the support bar can be inserted into the base, and then a locking bar with a locking block is provided on the box cover. After the overall assembly is completed, the locking block can be snapped into the base, so that the overall structural strength is improved, it is not easy to sag or collapse, and the sealing is ensured.

[0014] 2. The utility model places an ice bag in the base of the packaging box and then buckles a buckle cover with a through hole, so that the cake in the packaging box can be kept fresh, making the cake not easy to melt and not occupying external space. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-4 A cake packaging box with good sealing performance includes a base 1, a transparent enclosure 2 is placed on the upper end of the base 1, and a support bar 11 is slidably connected to the inside of the corner of the transparent enclosure 2. The support bar 11 is plugged into the base 1. A slot is provided at the upper end of the base 1, and the support bar 11 is inserted into the slot. The provision of the slot facilitates the positioning of the support bar 11 on the base 1. The top of the transparent enclosure 2 is slidably connected to the box cover 3, and the side of the box cover 3 is fixedly connected to the locking bar 8. The locking bar 8 contacts the base 1. A locking block 9 is fixedly connected to the locking bar 8, and the locking block 9 is clamped with the base 1. The upper end of the locking block 9 is fixedly connected to a card block 10, and the card block 10 is clamped with the base 1.
