[0024] Reference Figure 1-4 The present invention provides an anti-misalignment container cover, comprising: an inner cover 1 and an outer cover 2;

[0025] The inner side of the inner cover 1 is provided with an internal thread, and the outer top surface of the inner cover 1 is provided with an interlocking portion A3. The inner top surface of the outer cover 2 is provided with an interlocking portion B4, and the outer cover 2 wraps the inner cover 1 inside and can rotate relative to the inner cover 1; the top of the outer cover 2 has the ability to deform, and under normal conditions, there is a gap between the interlocking portion B4 set on the inner side of the top of the outer cover 2 and the interlocking portion A3 set on the outer top surface of the inner cover 1 to maintain a separation state, and at this time, the inner cover 1 does not rotate with the rotation of the outer cover 2.

[0026] When the top of the outer cover 2 is under pressure, the top of the outer cover 2 deforms inward so that the interlocking portion B4 arranged on the inner side of the top of the outer cover 2 is engaged with the interlocking portion A3 arranged on the outer top surface of the inner cover 1, thereby making the outer cover 2 and the inner cover 1 enter a circumferentially fixed connection state. At this time, the inner cover 1 can rotate with the rotation of the outer cover 2.

[0027] During use, when the container cover needs to be opened or closed, the outer cover 2 is pressed on the top while being twisted to make the interlocking portion B4 engage with the interlocking portion A3, and the inner cover 1 rotates as the outer cover 2 is twisted, thereby completing the work of opening or tightening the container cover. When the pressure on the top of the outer cover 2 is released, the top of the outer cover 2 is reset, and the interlocking portion B4 is separated from the interlocking portion A3, so that the inner cover 1 no longer rotates as the outer cover 2 is twisted, that is, when the outer cover 2 is rotated, the inner cover 1 does not move, which can prevent the container cover from being accidentally opened and improve the safety of use.

[0028] In this embodiment, the interlocking portion A3 is a convex structure or a concave structure provided on the outer top surface of the inner cover 1, and when the interlocking portion A3 is a convex structure provided on the outer top surface of the inner cover 1, the interlocking portion B4 is a concave structure or a convex structure provided on the inner top surface of the outer cover 2. When the interlocking portion A3 and the interlocking portion B4 are both convex structures, in the interlocking state, the interlocking portion A3 is on one side of the rotation direction of the interlocking portion B4, so that when the outer cover 2 is twisted, the interlocking portion B4 pushes the interlocking portion A3 to rotate with the inner cover 1. When the interlocking portion A3 is a convex structure and the interlocking portion B4 is a concave structure, in the interlocking state, the interlocking portion A3 is embedded in the interlocking portion B4, so that when the outer cover 2 is twisted, the interlocking portion B4 pushes the interlocking portion A3 to rotate with the inner cover 1. When the engaging portion A3 is a groove structure and the engaging portion B4 is a convex structure, in the engaging state, the engaging portion B4 is embedded in the engaging portion A3, so that when the outer cover 2 is twisted, the engaging portion B4 pushes the engaging portion A3 to rotate the inner cover 1.

[0029] Furthermore, in this embodiment, a plurality of anti-slip protrusions are evenly distributed on the circumference of the outer wall of the outer cover 2 to increase the friction of the circumferential wall of the outer cover 2, thereby facilitating the twisting of the outer cover 2.

[0030] Furthermore, there are multiple interlocking parts A3, which are evenly distributed circumferentially on the outer top surface of the inner cover 1; the number of interlocking parts B4 is consistent with the number of interlocking parts A3, and they are evenly distributed circumferentially on the inner top surface of the outer cover 2, so as to increase the driving effect of the outer cover 2 on the inner cover 1 when the outer cover 2 is twisted.

[0031] The outer cover 2 in this embodiment is sleeved on the inner cover 1 and is rotatably connected to the inner cover 1 , so that the outer cover 2 wraps the inner cover 1 inside thereof and can rotate relative to the inner cover 1 .

[0032] In addition, an undercut structure 5 is provided on the inner side of the port of the outer cover 2 , and the undercut structure 5 is stuck on the edge of the port of the inner cover 1 , so as to prevent the inner cover 1 from slipping out of the outer cover 2 by using the undercut structure 5 .

[0033] The inner side of the outer cover 2 is provided with a limiting ring extending inward, and the outer periphery of the inner cover 1 is provided with a limiting groove, in which the limiting ring is located, so as to form a rotating assembly of the outer cover 2 and the inner cover 1 and ensure the stability of the assembly of the two.

[0034] In addition, in order to be suitable for some occasions where exhaust is required, the present embodiment may also be provided with an air hole 6 on the inner cover 1, and an exhaust groove 7 is provided at the junction of the outer wall of the outer cover 2 and the inner wall of the inner cover 1, so that the gas passes through the air hole 9 into between the outer cover 2 and the inner cover 1, and is then discharged from the exhaust groove 7 between the two. In this way, this structural design prevents the air hole 9 from leaking out, which can avoid the problem of blockage of the air hole 9 and is more beautiful in appearance.

[0035] Furthermore, the exhaust port of the exhaust groove 7 is arranged at the port of the outer cover 2 or the inner cover 1, so that the gas is discharged from the lower end of the container cover, so as to further enhance the aesthetic appearance.

[0036] In addition, in order to be suitable for waterproof and breathable occasions, the present embodiment can cover the air holes 6 on the inner cover 1 with a waterproof and breathable membrane 8 to achieve a waterproof and breathable effect.

[0037] Furthermore, in this embodiment, an inner groove is provided on the outer top surface of the inner cover 1, the vent hole 9 is provided inside the inner groove, and the waterproof breathable membrane 8 is fixed inside the inner groove. This structural design facilitates the installation of the waterproof breathable membrane 8, and the inner groove can limit the installed waterproof breathable membrane 8, thereby ensuring the firmness of the installation of the waterproof breathable membrane 8.

[0038] Furthermore, the inner top surface of the outer cover 2 is provided with a plurality of protrusions 9 circumferentially evenly distributed around the vent holes 9, and all the protrusions 9 are located on the inner side of the inner groove and rest against the waterproof breathable membrane 8 to press the waterproof breathable membrane 8 and ensure the firmness of the installation of the waterproof breathable membrane 8.

[0039] In this embodiment, the outer cover 2 is made of plastic, and its top is a thin-walled structure so that its top has deformation capability.

[0040] As can be seen from the above, the present invention configures the container cover to be a combined structure of an inner cover 1 and an outer cover 2, and sets a fitting portion A3 on the outer top surface of the inner cover 1, and sets a fitting portion B4 on the inner top surface of the outer cover 2, and the outer cover 2 is rotatably mounted on the outside of the inner cover 1, and the top of the outer cover 2 has deformation ability. When the container cover needs to be unscrewed, it is necessary to press the top of the outer cover 2 to make the locking portion on the outer cover 2 fit with the fitting portion A3 on the inner cover 1, so that the outer cover 2 and the inner cover 1 are circumferentially fixed, and then when the outer cover 2 rotates, the inner cover 1 can be driven to rotate accordingly, so that the container cover and the corresponding container can be tightened or loosened. In a normal state, the inner cover 1 cannot rotate with the rotation of the outer cover 2. This structural design can prevent the container cover from being accidentally opened, thereby improving the safety of use.

[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
