The present invention will be further described below with reference to the accompanying drawings and an embodiment in an embodiment.

Please refer to FIG. 1 , which is a schematic three-dimensional structure diagram of a food storage tank 100 provided by the present application. The food storage tank 100 includes a main body 10 , a cover sheet 20 , a pull ring 30 and a guide 40 . The main body 10 is provided with a storage cavity 11 (shown in FIG. 8 ) and an opening 12 communicating with the storage cavity 11 ; the cover sheet 20 is connected to the main body 10 and covers the opening 12 to seal the storage cavity 11 ; the pull ring 30 is connected to the The cover sheet 20 is rotatably connected; the guide member 40 is arranged on the surface of the main body 10 and/or the cover sheet 20 facing the pull ring 30, and is located on the rotation path of the pull ring 30, and the guide member 40 protrudes from the cover sheet 20 by a height greater than The distance between the pull ring 30 and the cover sheet 20 .

To sum up, in the embodiment of the present application, the pull ring 30 is rotated and arranged on the cover sheet 20, and the guide member 40 is arranged on the rotation path of the pull ring 30. When the cover does not need to be opened, the distance between the pull ring 30 and the cover sheet 20 The distance between the openings 12 is relatively small to avoid accidental opening of the opening 12. When the cover needs to be opened, the pull ring 30 can be rotated to move to the top of the guide member 40. Since the guide member 40 protrudes from the cover 20 at a height greater than that of the pull ring 30 Therefore, the guide member 40 can increase the distance between the pull ring 30 and the cover sheet 20, so that it is convenient to pull the pull ring 30 to open the cover sheet 20, so that the opening of the cover is more convenient , to improve the user's opening experience.

Optionally, the storage cavity 11 can be used to store solid foods, such as cans, powders, etc., or the storage cavity 11 can also be used to store liquid foods, such as porridge, beverages, and the like.

Wherein, the main body 10 may be made of materials such as metal or alloy, so as to improve the safety of food preservation. Further, the main body 10 and the cover sheet 20 may be integrally formed, and a thinning groove 13 may be formed at the junction of the main body 10 and the cover sheet 20 to reduce the connection strength between the cover sheet 20 and the main body 10 . When the cover sheet 20 is pulled forcibly, the cover sheet 20 can be separated from the main body 10 along the thinning groove 13 , thereby opening the opening 12 . By integrally molding the cover sheet 20 and the main body 10 , the production efficiency of the food storage tank 100 can be improved.

Further, as shown in FIG. 1 , a welding portion 21 is connected between the cover sheet 20 and the side wall of the opening 12 , and the welding portion 21 is used to enhance the connection strength between the cover sheet 20 and the opening 12 .

Specifically, the welding portion 21 may be filled in a partial area of the thinning groove 13 to increase the connection strength between the cover sheet 20 and the main body 10 . When the cover sheet 20 is pulled forcibly, in the area where the welding part 21 is not provided, the cover sheet 20 and the main body 10 are easily separated due to the existence of the thinning groove 13 . The connection strength is large, and it is inconvenient to separate, so that the cover sheet 20 can be prevented from being separated from the main body 10 as a whole and falling into the storage cavity 11 from the opening 12 .

Further, as shown in FIG. 1 , a toggle portion 31 can be protruded on the surface of the pull ring 30 away from the cover sheet 20 . When the user toggles the pull ring 30 to rotate, the user can abut the toggle portion 31 and rotate by hand. . The setting of the toggle portion 31 can facilitate the user to operate by hand, thereby making it more convenient to open the cover.

Optionally, as shown in FIG. 1 , the toggle portion 31 may be disposed at the end of the pull ring 30 away from the rotational connection between the pull ring 30 and the cover sheet 20 . Specifically, the rotational connection between the pull ring 30 and the cover sheet 20 is the rotation axis A of the pull ring 30 relative to the cover sheet 20. By arranging the toggle portion 31 at the end of the pull ring 30 away from the rotation axis A, the toggle can be increased The distance between the moving part 31 and the rotation axis A, that is, to increase the distance between the toggle action force and the rotation axis A, so as to increase the lever arm of the toggle action force, thereby reducing the toggle action force, which is convenient for opening. cover.

Further, the toggle portion 31 and the welding portion 21 can be arranged on the same side of the pull ring 30 . For example, in some embodiments, the toggle portion 31 and the welding portion 21 may be disposed on the right side of the pull ring 30 at the same time. When the pull ring 30 is driven to rotate to the right by the toggle portion 31, the presence of the welding portion 21 will cause The separation force between the left side of the cover sheet 20 and the main body 10 is increased, thereby facilitating the separation of the left cover sheet 20 from the main body 10 .

It can be understood that, in some other embodiments, the toggle portion 31 and the welding portion 21 may be disposed on the left side of the pull ring 30 at the same time.

Further, in one embodiment, the height of the guide member 40 protruding from the cover sheet 20 may be set to be greater than or equal to twice the distance between the pull ring 30 and the cover sheet 20 .

Further, in some embodiments, along the rotation direction of the pull ring 30 , the height of the guide member 40 may be set to gradually increase.

For example, as shown in FIG. 1 , the pull ring 30 is rotated in a clockwise direction, and the height of the guide member 40 in the clockwise direction can be gradually increased, so as to stably lift the pull ring 30 relative to the height of the cover sheet 20 , and then it is convenient to drive the pull ring 30 to move, so as to make opening the cover more convenient.

The gradual increase in the height of the guide member 40 may mean that the height of the guide member 40 changes continuously, or the gradual increase in the height of the guide member 40 may also mean that the height of the guide member 40 changes in stages. Yes, within each segment, the heights of the guides 40 are equal and between adjacent segments, the heights of the guides 40 are gradually changed.

Since the pull ring 30 is on the guide member 40, the included angle between the pull ring 30 and the cover sheet 20 becomes larger. If the included angle of the pull ring 30 with respect to the cover sheet 20 is too large, the pull ring 30 will be broken, and the cover cannot be opened. Therefore, in this embodiment, when the pull ring 30 is located on the guide member 40, the included angle of the pull ring 30 relative to the cover sheet 20 may be smaller than the bending limit angle of the pull ring 30. The bending limit angle of the pull ring 30 specifically refers to the maximum angle at which the pull ring 30 can be bent before breaking. By arranging that when the pull ring 30 is located on the guide member 40, the included angle of the pull ring 30 relative to the cover sheet 20 is smaller than the bending limit angle of the pull ring 30, so that the pull ring 30 can be prevented from being broken and the cover cannot be opened.

Further, as shown in FIG. 1 , the top surface of the guide member 40 can be set to be a plane connected to the surface of the cover sheet 20 , that is, the height of the guide member 40 can be continuously increased, so that the pull-ring 30 can be moved more easily. move.

Or, in another embodiment, as shown in FIG. 2 , FIG. 2 is a partially enlarged schematic structural diagram of a food storage tank 100 in another embodiment of the present application. The guide member 40 may include a first guide portion 42 and a second guide portion 44. The first guide portion 42 and the second guide portion 44 are continuously arranged along the rotation direction of the pull ring 30. The height is smaller than that of the second guide portion 44 . In this way, when the pull ring 30 is pushed to move, the pull ring 30 will first move to the first guide portion 42 with a smaller height, and then gradually rise to the second guide portion 44 with a larger height. The amplitude of each lift of the pull ring 30 is reduced, thereby reducing the lifting resistance of the pull ring 30 .

Optionally, the top surface of the first guide portion 42 may be provided to smoothly connect the surface of the cover sheet 20 with the top surface of the second guide portion 44 . In this way, the resistance to movement of the pull ring 30 can be further reduced.

In a specific embodiment, the top surface of the first guide portion 42 may be set as an inclined surface inclined relative to the surface of the cover sheet 20 . Alternatively, in another embodiment, a chamfer or fillet may be formed at the intersection of the first guide portion 42 and the cover sheet 20 , and at the intersection of the first guide portion 42 and the second guide portion 44 Chamfered or rounded corners are formed to reduce the resistance of the pull ring 30 when it moves to the junction of the first guide portion 42 and the cover sheet 20 and the junction of the first guide portion 42 and the second guide portion 44, so as to facilitate The pull ring 30 continues to move to achieve a stable lift.

It is understandable that the guide member 40 may also be arranged in three or four sections, and may be arranged according to the shape and size of the pull ring 30 , which is not specifically limited in the embodiment of the present application. For example, a third guide part may be provided on the side of the second guide part 44 away from the first guide part 42 along the rotation direction of the pull ring 30 , and the height of the third guide part is greater than that of the second guide part 44 . By arranging the guide member 40 in multiple stages with gradually changing heights, the stability of the height of the pull ring 30 can be improved, and the lifting of the pull ring 30 is facilitated.

Further, as shown in FIG. 2 , the food storage tank 100 in the present application further includes an abutting portion 46 . The structures of the first guide portion 42 and the second guide portion 44 are similar to those in the above-mentioned embodiments, please refer to the descriptions in the above-mentioned embodiments, which will not be repeated here. The contact portion 46 is disposed on the side of the second guide portion 44 away from the first guide portion 42 along the rotation direction of the pull ring 30 , and the height of the second guide portion 44 is smaller than that of the contact portion 46 . In this way, when the pull ring 30 is moved to the second guide portion 44 , the abutting portion 46 will block the pull ring 30 to prevent the pull ring 30 from being displaced, and preventing the pull ring 30 from being skewed and causing the pull ring 30 to break .

Wherein, in order to improve the blocking effect of the abutting portion 46 on the pull ring 30, a step can be formed at the junction of the abutting portion 46 and the second guide portion 44, thereby increasing the resistance of the pull ring 30 to rotate and preventing the pull ring 30 from continuing to Rotating relative to the guide member 40 and removing from the guide member 40 causes the distance between the pull ring 30 and the cover sheet 20 to decrease.

Alternatively, the abutting portion 46 may not be connected with the guide member 40 , but may be provided on the main body 10 at an interval from the guide member 40 , so as to limit the rotation angle of the pull ring 30 and prevent the pull ring 30 from self-guiding 40 and out.

For example, in one embodiment, the abutting portion 46 may be provided at a position between the guide member 40 and the rotational connection between the pull ring 30 and the cover sheet 20, so that, compared with the above-mentioned embodiment, the abutting portion 46 can not only limit the rotation angle of the pull ring 30, but also shorten the protruding height of the abutting portion 46 relative to the main body 10 or the cover sheet 20, so as to prevent the abutting portion 46 from being bent when the height is large.

Optionally, the number of the guide pieces 40 may be set to one, and one guide piece 40 may be set on one side of the pull ring 30 .

Alternatively, the number of the guide members 40 can also be set to two, and the two guide members 40 can be respectively arranged on opposite sides of the pull ring 30 at intervals. In this way, no matter whether the user rotates the pull ring 30 to the left or to the right The height of the pull ring 30 can be raised, so as to satisfy customers with different switching habits.

A through hole 32 can also be opened on the pull ring 30, one of the guide members 40 is arranged in the through hole 32, and the other guide member 40 is arranged outside the through hole 32. In this way, when the user toggles the pull ring 30 , the side wall of the pull ring 30 surrounding the through hole 32 can be lifted through the guide member 40 disposed in the through hole 32, and at the same time, the outer periphery of the pull ring 30 can be lifted through another guide member 40. , in this way, the force of the pull ring 30 can be made more uniform.

Further, as shown in FIG. 1 , the main body 10 includes a bottom wall 14 , a top wall 15 and a side wall 16 connected between the top wall 15 and the bottom wall 14 , and the top wall 15 , the bottom wall 14 and the side wall 16 are enclosed to form In the storage cavity, the opening 12 is formed on the top wall 15 , and the cover sheet 20 is connected to the top wall 15 and covers the opening 12 .

Optionally, the top wall 15 and the bottom wall 14 may be configured in a circular shape, and the side walls 16 are arranged around the outer periphery of the top wall 15 and the bottom wall 14 , thereby forming a cylindrical food storage tank 100 . The shape and size of the top wall 15 and the bottom wall 14 may be the same or different, or the top wall 15 and the bottom wall 14 may also be oval, square, triangular, etc., which are not specifically limited in this application.

Further, as shown in FIG. 1 , the end of the side wall 16 protrudes from the side of the top wall 15 away from the bottom wall 14 to enclose the installation cavity 17 , and the guide member 40 and the pull ring 30 are arranged in the installation cavity 17 , And the height of the guide member 40 protruding from the top wall 15 does not exceed the height of the side wall 16 protruding from the top wall 15 . In this way, the guide member 40 and the pull ring 30 can be sunk in the installation cavity 17 to prevent the guide member 40 and the pull ring 30 from being damaged by contact with external objects or opening the cover by mistake.

Another aspect of the present application further provides a food storage tank 200, please refer to FIG. 4 and FIG. 5, FIG. 4 is a three-dimensional schematic diagram of the food storage tank 200 in another embodiment of the present application, and FIG. 5 is the food in FIG. 4.
