Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of blister product, and relates to a blister packaging box which is convenient to open and close. BACKGROUND

[0002] The blister packaging box is commonly used for packaging take-out meals, cakes, bulk food and the like, and comprises a box body and a cover sheet. The existing buckle cover modes of the blister packaging box are divided into two kinds. One is that the cover sheet is provided with a downwardly turned flange which can be matched with the horizontal flange on the box body and is sleeved outside the horizontal flange on the box body. The other is that the cover sheet is provided with a plurality of protrusions, and the box body is provided with notches matched with the protrusions to buckle the cover sheet by the close matching of the protrusions and the notches. However, the two modes have respective defects. The first mode is inconvenient to buckle and unbuckle, and it is difficult to open the cover sheet. Since the blister product is soft, the cover sheet or the box body is easily torn in the process of opening and closing the cover sheet, and the packaged objects in the box are easily scattered. The second mode is not tightly buckled and has poor sealing. SUMMARY

[0003] The utility model aims at the above problems existing in the prior art, and provides a blister packaging box which is convenient to open and close. The utility model aims to improve the opening and closing convenience.

[0004] The utility model discloses a blister packaging box which is convenient to open and close, characterized in that the box body and the cover sheet are rectangular, the outer circle of the box body is provided with four horizontal flanges matched with the four edges of the box body, the outer side of each horizontal flange is provided with a flange, the outer contour of the cover sheet is matched with the four horizontal flanges, the flange is provided with a plurality of protrusions, the upper surface of the horizontal flange is provided with notches matched with the protrusions, and the outer edge of the cover sheet can be clamped between the flange and the horizontal flange.

[0005] Further, the cover sheet is provided with an avoiding groove avoiding the protrusions.

[0006] The opening and closing connection positions of the blister packaging box are independent of each other, the four flanges are buckled on the respective horizontal flanges, the protrusions and the notches are tightly connected to limit the cover sheet, the sealing surface between the objects in the box body and the outside is greatly increased after the cover sheet is limited, the sealing effect is better, the blister packaging box is convenient to open and close, a large external force is not needed, the box body is not easily torn, and the objects in the box are not easily scattered. The avoiding groove can reduce the interference between the notches and the protrusions, and the cover sheet is also positioned, so that the cover sheet can be placed more accurately. BRIEF DESCRIPTION OF DRAWINGS

[0007] Figure 1 is a structural schematic view of the blister packaging box after the cover sheet is placed (the flange is not buckled on the horizontal flange).

[0008] Figure 2 is an exploded view of the blister pack.

[0009] In the figure, 1, the box body; 2, the cover piece; 3, the transverse flange; 4, the flap; 5, the protrusion; 6, the notch; 7, the avoidance slot. DETAILED DESCRIPTION

[0010] The following is a specific embodiment of the present application and further describes the technical scheme of the present application in conjunction with the accompanying drawings, but the present application is not limited to these embodiments.

[0011] As shown in the blister pack shown in Figure 1 and Figure 2 , comprising a rectangular box body 1 and cover piece 2, the outer ring of the box body 1 has four pieces of transverse flange 3 respectively matched with the four edges of the box body 1, the outer side of the transverse flange 3 has a flap 4, the outer contour of the cover piece 2 is matched with the four pieces of transverse flange 3, the flap 4 has a plurality of protrusions 5, the upper surface of the transverse flange 3 has a notch 6 matched with the protrusion 5, the outer edge of the cover piece 2 can be clamped between the flap 4 and the transverse flange 3, the cover piece 2 has an avoidance slot 7 avoiding the protrusion 5.

[0012] The opening and closing connection position of the blister pack is independent, four flanges are respectively buckled on the respective transverse flange 3, the protrusion 5 and the notch 6 are used to realize the limiting of the cover piece 2, after the cover piece 2 is limited, the sealing surface between the internal articles of the box body 1 and the outside world is greatly increased, the sealing effect is better, and in the process of opening and closing the packaging box, it is more convenient, it does not need large external force, it is not easy to tear the box body, and it is not easy to cause the external spilling of the articles in the box. The avoidance slot 7 can reduce the interference between the notch 6 and the protrusion 5, and at the same time, it is also a positioning for the cover piece 2, which can place the cover piece 2 more accurately.

[0013] The specific embodiments described in this paper are only illustrative of the spirit of the present application. Those skilled in the art to which the present application belongs can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, but will not deviate from the spirit of the present application or exceed the scope defined by the appended claims.
