[0002] The blister box currently used in production is designed as a split structure, which shows a certain degree of flexibility in the manufacturing and assembly process. In actual applications, the upper cover and the lower tray need to be placed on their own tray shelves during the production process so that they can be assembled according to the established process steps later.

[0003] However, when the upper covers are stacked during production, multiple upper covers are stacked together. Due to their structural limitations, it is difficult to separate the multiple upper covers after stacking. As a result, on the production assembly line, workers need to spend a lot of manpower to manually separate the upper covers, which reduces production efficiency and increases production costs.

[0005] To achieve the above-mentioned purpose, the utility model provides a cover body, wherein the cover body comprises a covering surface and a side wall, wherein the side wall encloses along the edge of the covering surface to form a cavity with an opening, and a plurality of the cover bodies can be sequentially sleeved through the cavity;

[0006] The side wall is provided with a plurality of abutment protrusions protruding outwardly on the outer side surface of the chamber, and the plurality of abutment protrusions are arranged at intervals along the circumference of the side wall;

[0007] When the plurality of cover bodies are sequentially sleeved, the cover body located at the upper part abuts against the abutting protrusion of the cover body located at the lower part.

[0008] In some embodiments of the present invention, the side of the abutting protrusion close to the covering surface is the first side, the side of the abutting protrusion away from the covering surface is the second side, and the protruding distance of the abutting protrusion gradually decreases from the first side toward the second side.

[0009] In some embodiments of the present invention, the distance from the first side to the covering surface is greater than the distance from the second side to the edge of the side wall.

[0010] In some embodiments of the present invention, the distance between the first side and the covering surface is greater than or equal to 2 mm, the distance between the first side and the side wall is 1-2 mm, and the distance between the second side and the side wall is 0-0.5 mm.

[0011] In some embodiments of the present invention, the distance between the first side and the covering surface is recorded as the width, and the ratio of the width to the length of the first side is 1:[7-10].

[0012] In some embodiments of the present invention, the abutting protrusion further includes an inclined plane, the inclined plane is connected to the first side and the second side, the inclined plane is arranged opposite to the side wall, and the angle between the inclined plane and the side wall is 17°-27°

[0013] In some embodiments of the present invention, the covering surface is rectangular, the side wall is enclosed at the edge of the covering surface to form a corner, and the abutting protrusion is located at one end of the side wall close to the corner.

[0014] The utility model also proposes a packaging box, comprising a box body and the cover body, wherein the box body comprises a placement surface and a surrounding portion, wherein the surrounding portion encloses the placement surface to form a receiving cavity with an opening, and the receiving cavity is used to place objects;

[0015] The chamber can be sleeved on the outer side of the enclosure portion.

[0016] In some embodiments of the utility model, a ring-shaped positioning rib is provided on the side of the covering surface facing the accommodating cavity;

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments 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 creative work are within the scope of protection of the utility model.

If the specific posture changes, the directional indication will also change accordingly.

[0034] In addition, the descriptions of "first", "second", etc. in the present utility model are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0035] See attached Figure 1-2 The utility model provides a cover body 100, which includes a cover surface 110 and a side wall 120. The side wall 120 is enclosed along the edge of the cover surface 110 to form a chamber with an opening, and multiple covers 100 can be sequentially mounted through the chamber;

[0036] The side wall 120 is provided with a plurality of abutting protrusions 130 protruding outwardly from the outer side surface of the chamber, and the plurality of abutting protrusions 130 are arranged at intervals along the circumference of the side wall 120;

[0037] When the multiple covers 100 are sequentially mounted, the cover 100 located at the top abuts against the abutting protrusion 130 of the cover 100 located at the bottom.

[0038] The cover body 100 based on the above technical features is provided with a plurality of abutting protrusions 130 on the outer side surface of the side wall 120, so that when multiple cover bodies 100 are stacked and covered, the side wall 120 of the upper cover body 100 can abut against the abutting protrusions 130 of the lower cover body 100. Compared with the traditional stacked cover bodies 100 that are bonded together, an abutting gap is formed by the abutting protrusions 130 abutting against the edges of the side walls 120 between the upper and lower adjacent cover bodies 100. At the same time, the abutting protrusions 130 ensure that a larger gap is still retained between the cover bodies 100 after stacking, thereby reducing the contact friction between the cover bodies 100 and avoiding the increase of atmospheric pressure on the upper cover due to the sealed stacking between the cover bodies 100, so that mechanical equipment can easily separate and pick up the adjacent stacked cover bodies 100 through the gap formed by the abutting protrusions 130, without the need for manual picking and separation, thereby improving work efficiency.

[0039] It should be noted that the number of the abutment protrusions 130 may be 2, 3, 4 or more, and the abutment protrusions 130 may be abutted against the upper cover body 100 by being symmetrically arranged or spaced apart, and the specific number is not further limited herein.

[0040] Among them, the side of the abutting protrusion 130 close to the covering surface 110 is the first side 131, and the side of the abutting protrusion 130 away from the covering surface 110 is the second side 132. The protruding distance of the abutting protrusion 130 gradually decreases from the first side 131 toward the second side 132. By making the vertical cross-section present an inverted cone-like shape, the force on the abutting protrusion 130 is more stable, thereby improving the structural stability of the abutting protrusion 130, avoiding excessive number of cover bodies 100 above the abutting protrusion 130, causing deformation of the abutting protrusion 130 and affecting the structural quality of the cover body 100, thereby achieving stable stacking of a large number of cover bodies 100 and improving the degree of automation.

[0041] Furthermore, the distance between the first side 131 and the covering surface 110 is greater than the distance between the second side 132 and the edge of the side wall 120, so as to ensure that when the upper and lower covers 100 are stacked, there is enough overlapping space to prevent the two from slipping off.

[0042] Among them, the distance between the first side 131 and the covering surface 110 is recorded as the width, and the ratio of the width to the length of the first side 131 is 1: [7-10]. While meeting the resistance width, the abutment protrusion has a sufficient length, and thus has a sufficient abutment area to stably abut against the upper cover body 100, reducing the protruding width of the abutment protrusion 130 while meeting the demand for stable abutment.

[0043] Furthermore, the abutment protrusion 130 also includes an inclined plane, which is connected to the first side 131 and the second side 132. The inclined plane is arranged relative to the side wall 120, and the angle between the inclined plane and the side wall 120 is 17°-27°. By controlling the angle between the inclined plane and the side wall 120, the abutment protrusion 130 can maintain the first side 131 and the width of the first side 131 at a certain height, ensuring that the abutment protrusion 130 can be stably supported while facilitating demoulding, and avoiding the angle being too large or too small to affect the structural stability of the abutment protrusion 130 or affect demoulding.

[0044] Specifically, the distance between the first side 131 and the cover surface 110 is greater than or equal to 2mm, which is convenient for achieving the abutment of the side wall 120 while avoiding the slippage of the side wall 120 due to the small distance of the first side 131. The distance between the first side 131 and the side wall 120 is 1-2mm, and the distance between the second side 132 and the side wall 120 is 0-0.5mm, which avoids the first side being too narrow or the second side being too wide, which is not conducive to the stable stacking of the upper cover. When the first side of the abutting protrusion 130 is too wide, the slope of the abutting protrusion 130 narrowing from top to bottom will increase, making it difficult to form in the blister process and affecting the smooth demoulding of the product.

[0045] In this embodiment, the covering surface 110 is rectangular, and the side wall 120 is enclosed at the edge of the covering surface 110 to form a corner. The abutment protrusion 130 is located at the end of the side wall 120 close to the corner. By making the abutment protrusion 130 located at the end of the side wall 120 close to the corner, the structural stability between the abutment protrusion 130 and the side wall 120 is further improved, ensuring that effective and stable support can be achieved when multiple cover bodies 100 are stacked.

[0046] See attached Figure 1-4 The utility model also proposes a packaging box 1000, including a box body 200 and a cover body 100. The specific structure of the cover body 100 refers to the above embodiment. Since the packaging box 1000 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0047] Among them, the box body 200 includes a placement surface 210 and an enclosure portion 220. The enclosure portion 220 encloses the placement surface 210 to form a accommodating cavity with an opening, and the accommodating cavity is used to place objects. The chamber can be covered and sleeved on the outer side of the enclosure portion 220, thereby achieving the covering of the accommodating cavity, so as to meet the closed storage of objects in the accommodating cavity.

[0048] Furthermore, a ring-shaped positioning rib 140 is provided on the side of the covering surface 110 facing the accommodating cavity; when the cover body 100 is covered on the box body 200, the positioning rib 140 abuts against the bottom surface of the accommodating cavity, and the positioning rib 140 abuts against the outer contour of the placed object to achieve positioning of the placed object, thereby avoiding the displacement of the object in the accommodating cavity during transportation.

[0049] Specifically, two or more support protrusions 150 are arranged at intervals on the side of the covering surface 110 facing the accommodating cavity, and the support protrusions 150 are arranged in the positioning ribs 140; when the cover body 100 is covered on the box body 200, the support protrusions 150 abut against the bottom surface of the accommodating cavity; by making the support protrusions 150 located in the positioning ribs 140, while the support protrusions 150 increase the positioning and abutting effect on the placed objects, the support protrusions 150 form a supporting structure between the covering surface 110 and the accommodating cavity, thereby strengthening the structural strength between the covering surface 110 and the accommodating cavity and reducing the situation where the packaging box 1000 is compressed and causes the covering surface 110 to be concave and press against the placed objects.

[0050] In some embodiments of the utility model, a convex buckle position 160 is provided on the side of the side wall 120 facing the enclosure 220, and a concave buckle position 230 is provided on the side of the enclosure 220 opposite to the convex buckle position 160, and the convex buckle position 160 and the concave buckle position 230 are arranged opposite to each other; when the cover body 100 is covered on the box body 200, the convex buckle position 160 can be engaged with the corresponding concave buckle position 230, and the positioning buckling connection between the box body 200 and the cover body 100 is achieved by the buckling between the concave buckle position 230 and the convex buckle position 160, thereby improving the connection stability between the box body 200 and the cover body 100.

[0051] Among them, the distance between the protruding end point of the convex buckle position 160 and the covering surface 110 is smaller than the distance between the abutting protrusion 130 and the covering surface 110, so as to avoid interference between the side wall 120 and the convex buckle position 160 when multiple cover bodies 100 are stacked and covered, thereby preventing the side wall 120 from interfering with the convex buckle position 160 and failing to effectively achieve stable abutment with the abutting protrusion 130.

[0052] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
