For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0044] Please refer to Figure 1 and Figure 2 The embodiment of the utility model provides a packaging container 10 with a tearable cover film to prevent material splashing. In this embodiment, the packaging container 10 with a tearable cover film to prevent material splashing is a cup, the shape of the cup is a truncated cone, and the diameter of the lower part of the cup is smaller than the diameter of the cup mouth. In other embodiments, the packaging container 10 with a tearable cover film to prevent material splashing can also be a bottle, or other structures capable of containing liquid products.

[0045] Specifically, the cover film tearable packaging container 10 for preventing material splashing includes a container body 200 and a cover film 100, the container body 200 includes a container mouth 210, the end surface of the container mouth 210 is provided with a protrusion 211, and the cover film 100 is heat-sealed with the container mouth 210 and the protrusion 211, so that the cover film 100 closes one end of the container mouth 210. Since the cover film 100 is heat-sealed with the container mouth 210 and the protrusion 211, the protrusion 211 of this embodiment can not only bear the role of pressure relief, but also block the spraying of a small amount of material during the pressure relief process, thereby improving the user experience.

[0046] In this embodiment, the container body 200 is a cup body, the container mouth 210 is a cup mouth, the cup mouth is annular, the raised portion 211 is also annular and is located on the cup mouth, and the raised portion 211 protrudes from the plane where the cup mouth is located.

[0047] In this embodiment, the size of the protrusion 211 includes a first size and a second size configured to enclose the width of the protrusion 211, and the first size is smaller than the second size. Since the protrusion 211 of this embodiment is a circular ring structure, it can be understood that the first size is the inner diameter of the protrusion 211, and the second size is the outer diameter of the protrusion 211.

[0048] The dimensions of the container mouth 210 also include a third dimension and a fourth dimension configured to be the thickness of the end surface surrounding the container mouth 210, and the third dimension is smaller than the fourth dimension. Since the container mouth 210 of this embodiment is also a circular ring structure, it can be understood that the third dimension is the inner diameter of the container mouth 210, and the fourth dimension is the outer diameter of the container mouth 210.

[0049] The annular structure of the protrusion 211 of this embodiment is completely accommodated between the inner and outer diameters of the container mouth 210. Therefore, the diameter relationship between the protrusion 211 and the container mouth 210 of this embodiment satisfies: the third dimension < the first dimension < the second dimension < the fourth dimension.

[0050] Among them, the meanings of the above-mentioned first size, second size, third size and fourth size may be slightly different depending on the shape of the tearable packaging container 10 with a cover film to prevent material splashing. For example, in this embodiment, when the shape of the tearable packaging container 10 with a cover film to prevent material splashing is a truncated cone structure, the first size, second size, third size and fourth size all represent diameters.

[0051] In other embodiments, the plane structure of the container mouth 210 of the tearable packaging container 10 for preventing material splashing may also be a polygon, such as a rectangle, square, triangle, pentagon or hexagon. When the plane structure of the container mouth 210 is a polygon, the shape of the protrusion 211 should match the shape of the container mouth 210. For example, if the plane structure of the container mouth 210 is a rectangle, the plane shape of the protrusion 211 is also a rectangle. That is, the container mouth 210 and the protrusion 211 are both square ring structures.

[0052] like Figure 3 As shown, when both the container mouth 210 and the raised portion 211 are square ring structures, the first dimension, the second dimension, the third dimension and the fourth dimension of the container mouth 210 and the raised portion 211 all represent the side length, that is, length × width, or the side length of each side of the container mouth 210 and the raised portion 211 in one-to-one correspondence. It should be further explained that the size relationship between the first dimension, the second dimension, the third dimension and the fourth dimension refers to: the size relationship between the side lengths of each side in one-to-one correspondence. For example, the length of the first dimension of the raised portion 211 is smaller than the length of the second dimension, and the width of the first dimension of the raised portion 211 is smaller than the width of the second dimension.

[0053] In this embodiment, the protrusion 211 is an annular structure, while in other embodiments, the protrusion 211 may also be a fan-shaped or a broken line-shaped structure.

[0054] For example, Figure 4 As shown, when the container mouth 210 is a circular ring, the protrusion 211 can be a fan ring, the width of the fan ring can account for 1 / 4 to 1 / 2 of the circular ring surface of the container mouth 210, and the height of the two ends of the fan ring of the protrusion 211 can be gradually reduced, and then connected with the container mouth 210. The user can open the protrusion 211 with a fan ring structure, so that the protrusion 211 can play the role of pressure relief and splash prevention.

[0055] For example, Figure 5As shown, when the container mouth 210 is a square ring structure, the protrusion 211 can also be a broken line shape, that is, the protrusion 211 is arranged on two adjacent sides of the square ring and connected to each other. The user can open the protrusion 211 with a broken line structure, so that the protrusion 211 plays the role of pressure relief and splash prevention.

[0056] The structures of the protrusions 211 in the above embodiments are all composed of smooth lines. In other embodiments, the protrusions 211 may also be the above-mentioned square ring, circular ring or fan-shaped structure composed of broken lines, such as Figure 6 shown.

[0057] The tearable packaging container 10 for preventing material splashing provided in this embodiment has the following working principle: by providing a circular raised portion 211 and cooperating with a circular container mouth 210, the raised portion 211 is completely accommodated between the inner and outer diameters of the container mouth 210, and the cover film 100 is heat-sealed to the raised portion 211 and the container mouth 210. When the cover film 100 is torn, the pressure in the container body is released from the torn opening, and a small amount of content will be blocked by the raised portion 211, thereby preventing the content from splashing.

[0058] like Figure 7 As shown, another embodiment of the utility model provides a tearable packaging container 10 for preventing material splashing, and its structure is similar to the above structure, except that the outer diameter of the protrusion 211 is equal to the outer diameter of the container mouth 210, that is, the second dimension is equal to the fourth dimension. Therefore, a step-like structure is formed between the container mouth 210 and the protrusion 211 of the tearable packaging container 10 for preventing material splashing of the present embodiment, and the step height of the protrusion 211 is higher than the height of the container mouth 210. The cover film 100 is heat-sealed to the container mouth 210. When the cover film 100 is torn, due to the step-like structure of the protrusion 211, the material splashed when the pressure in the container is released is blocked by the protrusion 211, thereby preventing the material from splashing onto the user.

[0059] In order to further realize the air release function and prevent material splashing, the utility model also provides another implementation method, which is as follows:

[0060] The tearable packaging container 10 for preventing material splashing of the present embodiment is still a cup, and the outer shape of the cup is still not a truncated cone, but the inner surface of the cup is a semicircular arc structure, and the cup mouth has the same Figure 7 A similar protrusion 211 is provided on the cover film 100 to increase the structure for venting air.

[0061] like Figure 8As shown, the cover film 100 includes a stacked heat-sealing layer 120, a barrier layer 130, and a printing layer 140. The heat-sealing layer 120 is heat-sealed to the container mouth 210, the barrier layer 130 is located on the side of the heat-sealing layer 120 away from the container mouth 210, and the printing layer 140 is in contact with the barrier layer 130 and is located on the side away from the heat-sealing layer 120.

[0062] like Fig. 9 As shown, in order to facilitate tearing of the cover film 100, the cover film 100 also includes an open end 110, which protrudes laterally from the cover film 100 body. Since the container of this embodiment is a truncated cone-shaped cup, the shape of the cover film 100 is also adaptively designed to be circular. When the open end 110 of the cover film 100 protrudes laterally from the circular surface, the cover film 100 provided in this embodiment has a teardrop-shaped structure as a whole.

[0063] The barrier layer 130 is provided with an opening section 111, which is a zigzag line segment and is provided at the outer annular surface of the connecting portion 122 corresponding to the opening end 110. The user can grasp the opening end 110 of the cover film 100 and then separate the cover film 100 from the container mouth 210 through the opening section 111.

[0064] Furthermore, the heat sealing layer 120 includes an annular connecting portion 122 and a partitioning portion 123 filled inside the connecting portion 122, the connecting portion 122 is used to connect with the container mouth 210, when the film layer is away from the container mouth 210, the connecting portion 122 and the partitioning portion 123 can be selectively separated; the connecting portion 122 is also provided with an air release area 121 corresponding to the opening end 110, and the air release area 121 is located on the side of the connecting portion 122 close to the partitioning portion 123.

[0065] In this embodiment, the air release area 121 is an air release hole, and the aperture of the air release hole is relatively small, which is not only conducive to air release, but also can prevent the material from spraying out of the air release hole.

[0066] There are three vent holes in this embodiment, which are evenly spaced and arranged in a row. The vent holes have the same shape, which is a quadrilateral, and the protrusion direction is toward the opening end 110, so that the air pressure can be discharged from the vent holes at the moment of opening.

[0067] The air leakage hole can be arranged inside the raised portion 211 of the container mouth 210, or can be arranged outside the raised portion 211 of the container mouth 210, that is, in the pressure relief process, the gas in the container is firstly discharged through the air leakage hole or the raised portion 211. In this embodiment, in order to improve the air release effect, the gas in the container is firstly discharged through the air leakage hole and then through the raised portion 211, so the air leakage hole is located at one end of the raised portion 211 close to the cavity in the container for holding materials.

[0068] Therefore, the present embodiment provides a tearable packaging container 10 with a cover film that prevents material splashing, and its working principle is: at the moment when the cover film 100 is torn, the pressure in the container is discharged through the vent hole, and the small amount of material carried is blocked by the protrusion 211 to prevent the material from splashing.

[0069] In other embodiments, the structure of the vent hole may also be changed, for example, Fig.10 The three horizontally arranged acute triangle structures shown, or Fig.11 The three laterally arranged semicircular structures shown, or Fig.12 An obtuse triangle structure as shown, or Fig.13 The five horizontally arranged linear structures shown, or Fig.14 The two vertically arranged acute triangle structures shown, or Fig.15 An acute triangle structure is shown.

[0070] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
