Description

Technical Field

[0001] The utility model relates to the technical field of food packaging, in particular to a food packaging box. Background Art

[0002] Most existing food packaging cans consist of a can body and a top easy-tear cover. During manufacturing, the can mouth of the can body and the top easy-tear cover are generally sealed using special mechanical equipment.

[0003] like Figure 1 and Figure 2 As shown, the mechanical sealing operation is to first place the top easy-tear cover 08 on the mouth of the can body 07, and then place the can body 07 and the top easy-tear cover 08 together on the upper end of the workbench 06. The sealing machine can generally include the following: Figure 1 In the structure shown, when the start button is pressed on the sealing machine, the motor 02 drives the connecting frame 03 to rotate, and the connecting frame 03 drives the pressing roller 04 to rotate. At the same time, the hydraulic rod 05 pushes the connecting frame 03 downward, so that the pressing roller 04 folds the outer edge of the top easy-tear cover 08, and the edge of the top easy-tear cover 08 is neatly folded to form a folding part 010, forming an elliptical seal, and finally obtaining Figure 2 The packaging can shown.

[0004] However, during actual operation, we found that workers may start sealing without placing the top tear-off cover accurately at the expected position on the can opening due to hand shaking or haste. As a result, the top tear-off cover falls directly from the can opening during sealing, causing sealing failure and requiring a second seal. Therefore, it is necessary to design a structure that can pre-position the top tear-off cover and the can opening. Utility Model Content

DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0038] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the usual meanings understood by people with ordinary skills in the field to which this utility model belongs. The "first", "second" and similar words used in this utility model do not indicate any order, quantity or importance, but are only used to distinguish different components. "Include" or "comprise" and similar words mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative position relationships. When the absolute position of the object being described changes, the relative position relationship may also change accordingly.

[0039] like Figure 3 As shown, a food packaging box includes a can body 1 with an opening at the top; a cover body 2 adapted to the opening of the can body 1, the cover body 2 being provided with an easy-tear cover 3; a first engaging member connected to the cover body 2; and a second engaging member provided on the inner wall of the can body 1. When in use, the first engaging member and the second engaging member are engaged and locked with each other to limit relative movement between the cover body 2 and the can body 1.

[0040] The above technical solution can facilitate the pre-positioning of the cover 2 and the can body 1. During production, the worker places the cover 2 at the opening of the can body 1, presses the cover 2 to drive the first locking component and the second locking component on the inner wall of the can body 1 to contact each other until the first locking component and the second locking component are locked with each other, thereby pre-fixing the cover 2 at the opening of the can body 1. After that, the can body 1 and the cover 2 can be placed together on the work station of the sealing machine for processing. Since the first locking component and the second locking component limit the movement between the can body 1 and the cover 2, the cover 2 always remains inseparable from the can body 1 during the subsequent process of pressurizing the edge of the cover 2 by the sealing machine, preventing the cover 2 from deviating from the expected position and ensuring the processing quality.

[0041] like Figure 3 As shown, in this embodiment, the first engaging component is an arc-shaped plate 13 provided at the bottom end of the cover body 2, and an engaging member 14 is provided at the bottom end of the arc-shaped plate 13 and extends radially along the central axis of the cover body 2; the second engaging component is an inner sealing ring 11 provided on the inner wall of the can body 1 and extends radially along the central axis of the can body 1, and the inlet edge of the inner sealing ring 11 is turned outward to form an arc-shaped curling edge 12 that engages with the engaging member 14;

[0042] The above technical solution can be used to conveniently pre-position the cover body 2 at the upper opening of the can body 1. Specifically, during manufacturing, since the curved plate 13 and the inner sealing ring 11 are provided, when the worker places the cover body 2 on the can body 1, he presses the cover body 2 to drive the curved plate 13, and the curved plate 13 drives the locking member 14 to engage with the curved curled edge 12 of the inner sealing ring 11, thereby achieving the initial fixation of the cover body 2 on the can body 1 to prevent the cover body 2 from falling. Then the can body 1 can be placed in the sealing machine for processing. During the process of applying pressure to the edge of the cover body 2, the cover body 2 will not move relative to the can body 1.

[0043] like Figure 3 As shown, in this embodiment, the outer edge of the cover body 2 has a folded edge 9 for sealing, and the folded edge 9 is provided with an annular clamping portion 10 extending radially inward along the central axis of the cover body 2. The opening of the can body 1 is provided with an annular protrusion 8 extending radially outward along the central axis of the can body 1, and the annular protrusion 8 is engaged with the annular clamping portion 10;

[0044] The above technical solution can be used to fix the cover body 2 to the upper opening of the can body 1 to prevent the food in the can body 1 from leaking out of the opening. Compared with the existing technology, the provision of an annular snap-fit ​​portion 10 and an annular protrusion 8 can further improve the connection stability of the cover body 2 and improve the sealing performance.

[0045] like Figure 3As shown, in this embodiment, the packaging box further includes: an easy-tear film 15, which is arranged at the upper end of the arc-shaped curling edge 12 to seal the entrance of the inner sealing ring 11. The easy-tear film 15 is an airtight film, which can be a waterproof plastic film. It is arranged at the upper end of the arc-shaped curling edge 12 to seal the entrance of the inner sealing ring 11;

[0046] The above technical solution can better seal the food. After opening the easy-tear cover 3, the food inside the can body 1 can be taken out by tearing off the easy-tear film 15, thereby providing dual protection for the food through the easy-tear cover 3 and the easy-tear film 15.

[0047] like Figure 3 As shown, in this embodiment, the easy-tear cover 3, the arc-shaped plate 13 and the easy-tear film 15 together form a receiving space for placing objects;

[0048] The above technical solution can be used to conveniently place objects such as disposable gloves or spoons in the accommodating space of the packaging can, so that consumers can eat food more hygienically.

[0049] like Figure 8 As shown, in this embodiment, the arc plate 13 is a complete annular plate structure;

[0050] The above technical solution can ensure that the accommodating space does not leak objects, and the curved plate 13 can be set as follows: Figure 8 The annular plate structure shown in the figure provides a better sealing effect for the accommodating space.

[0051] like Figure 4 、 Figure 6 and Figure 7 As shown, in this embodiment, the packaging box further includes: a fixed plate 16, which is arranged at the bottom of the cover body 2; a rotating plate 17, with rotating shafts 18 provided at both ends, and the rotating shafts 18 cooperate with the rotating holes provided in the fixed plate 16; an annular wall 19, which is provided on the side of the rotating plate 17 that is in contact with the easy-tear cover 3 to enclose an area for placing objects; a spring 20, one end of which is connected to the bottom of the easy-tear cover 3, and the other end of the spring 20 is connected to the rotating plate 17;

[0052] The above technical solution can be used to fix objects such as disposable gloves or spoons. After removing the easy-tear cover 3, to prevent the objects from shaking and falling out during transportation, the rotating plate 17 can be pressed to rotate the rotating shaft 18 of the rotating plate 17 around the fixed plate 16, so that one side of the rotating plate 17 is tilted up, and the spoon or disposable gloves located in the annular wall 19 can be taken out, and the objects can be used to take out food.

[0053] like Figure 3 and Figure 5As shown, in this embodiment, the packaging box further includes: a pull ring 4, which is rotatably arranged on the upper end of the easy-tear cover 3; an easy-tear groove 5, which is opened at the junction of the easy-tear cover 3 and the cover body 2;

[0054] The above technical solution facilitates tearing off the easy-tear cover 3 . When in use, the user holds the pull ring 4 and pulls the easy-tear cover 3 upwards to move along the easy-tear groove 5 , thereby opening the easy-tear cover 3 .

[0055] like Figure 3 As shown, in this embodiment, the upper end of the cover body 2 is provided with a groove 6 that matches the bottom end of the can body 1; the bottom of the can body 1 is provided with a cavity 7;

[0056] The above technical solution can facilitate stacking of each food packaging can, and the concave cavity 7 can improve the stability of the center of gravity at the bottom of the can body 1 to prevent it from tipping over.

[0057] Working principle: When in use, hold the pull ring 4 and pull the easy-tear cover 3 upward to move along the easy-tear groove 5, so that the easy-tear cover 3 can be pulled open, and then the easy-tear film 15 can be torn off to take out the food inside the can body 1. In order to take out the food more hygienically, the rotating plate 17 can be pressed to make the rotating shaft 18 of the rotating plate 17 rotate around the fixed plate 16, so that one side of the rotating plate 17 is tilted, and objects such as a spoon or disposable gloves located in the annular wall 19 are taken out to take out the food. At the same time, due to the provision of the inner sealing ring 11, it can be avoided that excessive force is applied when tearing the easy-tear film 15 to prevent the food from spilling, thereby preventing waste;

[0058] And during manufacturing, since the curved plate 13 and the inner sealing ring 11 are provided, when the worker places the cover 2 on the can body 1, he presses the cover 2 to drive the curved plate 13, and the curved plate 13 drives the locking part 14 to engage with the curved curled edge 12 of the inner sealing ring 11, thereby achieving the initial fixation of the cover 2 on the can body 1 to prevent the cover 2 from falling. Then the can body 1 can be placed in the sealing machine for processing. During the process of applying pressure to the edge of the cover 2, the cover 2 will not move relative to the can body 1, preventing the cover 2 from flying out, which is safer during manufacturing.

[0059] Those skilled in the art should understand that the discussion of any of the above embodiments is merely illustrative and is not intended to imply that the scope of the present invention (including the claims) is limited to these examples. Within the scope of the present invention, the technical features in the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.

[0060] The present invention is intended to cover all such substitutions, modifications and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
