[0028] The following is a detailed description of the structure of this utility model based on the accompanying drawings. However, the following description is not intended to limit this utility model. Changes, substitutions, combinations, deletions, etc., can be made to the constituent elements of the technical solution without departing from the spirit of this application.

[0029] <The overall structure of the cup>

[0030] exist Figure 1 A perspective view of the cup 1 of this application is shown in the figure, as follows: Figure 1As shown, the cup 1 has a cup body 3 and a cup cover 2, the cup body 3 is a cylinder with an open upper end for containing liquid, the cup cover 2 is a cylinder with an open lower end opposite to the cup body 3, the cup cover 2 is connected to the cup body 3 via a connecting piece 4, thus the open upper end of the cup body 3 is closed by the cup cover 2 to prevent liquid from flowing out. The cup 1 further has an automatic locking member 5 formed at the connection of the cup cover 2, the cup body 3 and the connecting piece 4.

[0031] In Figure 2 a plan view of the cup 1 is shown, Figure 2 the A-A view in Figure 3 the structure observed by the view angle of the A-A view is shown.

[0032] As Figure 3 shown, the connecting piece 4 is a cylinder with an open upper end and an open lower end, has an opening 15 extending through in the up-down direction, the lower side of the connecting piece 4 is threadedly combined with the cup body 3 in a detachable manner, and the cup cover 2 is threadedly connected to the upper side of the connecting piece 4 in a detachable manner. A filter screen can be provided in the opening 15.

[0033] <Automatic locking member>

[0034] The automatic locking member 5 of the present application will be described in detail below. Figure 3

[0035] As Figure 3 shown, the automatic locking member 5 has a first receiving portion 8, a second receiving portion 7, a third receiving portion 13 and a fourth receiving portion 14. Among them, the first receiving portion 8 and the fourth receiving portion 14 are provided on the connecting piece 4, the second receiving portion 7 is provided on the cup cover 2, and the third receiving portion 13 is provided on the cup body 3.

[0036] As Figure 3 shown, the first receiving portion 8 is provided on the connecting piece 4, the second receiving portion 7 is provided on the cup cover 2, when the cup cover 2 and the connecting piece 4 are threadedly connected together, the second receiving portion 7 is opposite to and communicates with the first receiving portion 8 in the up-down direction, a first rotation-stopping member 10 is received in the first receiving portion 8, the first rotation-stopping member 10 is movably installed in the first receiving portion 8, and the first rotation-stopping member 10 is used to limit the relative rotation between the cup cover 2 and the connecting piece 4 in the inverted state of the cup.

[0037] The length of the first rotation-stopping member 10 in the up-down direction is less than the length of the first receiving portion 8 in the up-down direction, thus when the cup 1 is placed upright, Figure 3 ​(As shown in the diagram), the first anti-rotation member 10 is entirely housed within the first storage section 8. When the cup is inverted, the first anti-rotation member 10 slides downwards. Since the second storage section 7 and the first storage section 8 are opposite and connected in the vertical direction, a portion of the first anti-rotation member 10 can slide into the second storage section 7. Since the length of the first anti-rotation member 10 in the vertical direction is greater than the length of the second storage section 7 in the vertical direction, the first anti-rotation member 10 will not slide entirely into the second storage section 7. A portion of the first anti-rotation member 10 enters the second storage section 7, while the other portion remains within the first storage section 8. That is, the first anti-rotation member 10 enters the second storage section 7 while being housed in the first storage section 8.

[0038] When the cup 1 is inverted, the first anti-rotation member 10 is located simultaneously in the first storage part 8 (located in the connector 4) and the second storage part 7 (located in the cup lid 2). Therefore, the first anti-rotation member 10 acts like a latch, locking the cup lid 2 at the connection between the cup lid 2 and the connector 4, preventing the cup lid 2 from rotating relative to the connector 4. This prevents the user from unscrewing the cup lid 2 from the connector 4. Thus, it prevents the user from accidentally unscrewing the cup lid 2 when the cup 1 is inverted.

[0039] Alternatively, the cross-sectional areas of both the first storage section 8 and the second storage section 7 can be larger than the cross-sectional area of ​​the first anti-rotation member 10. Therefore, the first anti-rotation member 10 can slide freely within the first storage section 8 and the second storage section 7. When the cup 1 is placed upright, the first anti-rotation member 10 is entirely housed within the first storage section 8. At this time, the first anti-rotation member 10 is not located at the connection between the lid 2 and the connector 4, thus not hindering the user from unscrewing the lid 2 from the connector 4. When the cup 1 is inverted, the first anti-rotation member 10 slides downwards as the cup 1 is inverted, entering the second storage section 7 while being housed within the first storage section 8. This prevents the lid 2 from rotating relative to the connector 4, thus preventing the user from unscrewing the lid 2 from the connector 4.

[0040] It could also be, such as Figure 3 As shown, a portion of the first anti-rotation member 10 protrudes from the first storage portion 8. Therefore, the user can determine whether the cup 1 is upright or inverted based on the protruding portion of the first anti-rotation member 10. Furthermore, if the first anti-rotation member 10 accidentally gets stuck and cannot move with the cup 1's orientation, the user can move the first anti-rotation member 10 by adjusting the protruding portion, thus releasing the stuck state of the first anti-rotation member 10.

[0041] Preferably, the second receiving portion 7 is fixed with a magnet 6, and the first rotation-stopping member 10 is formed of a material that can be attracted by the magnet 6. When the first rotation-stopping member 10 enters the second receiving portion 7, the magnet 6 contacts the first rotation-stopping member 10, thereby magnetically attracting the first rotation-stopping member 10 to the magnet 6, so as to maintain the state that the first rotation-stopping member 10 enters the second receiving portion 7. In this case, the first receiving portion 8 is formed on the outer circumferential surface of the connecting member 4, a long hole 9 is formed on the outer circumferential surface of the first receiving portion 8, and a protruding portion 11 is formed on the first rotation-stopping member 10, which protrudes from the long hole 9.

[0042] Thus, when the cup 1 is inverted, the first rotation-stopping member 10 slides to the second receiving portion 7 and is magnetically attracted to the magnet 6, and the protruding portion 11 slides in the long hole 9 and stops at a certain position. The user can clearly determine the state of the cup 1 according to the position of the protruding portion 11. The first rotation-stopping member 10 reliably functions as a latch to prevent the user from mistakenly opening the cup cover 2. When the user wants to open the cup cover 2, the user places the cup 1 upright, and slides the first rotation-stopping member 10 back into the first receiving portion 8 by jiggling the protruding portion 11, so as to release the latching state.

[0043] As to the structure that the first rotation-stopping member 10 partially protrudes from the first receiving portion 8, it is not limited to the structure that the protruding portion 11 protrudes from the long hole 9. The first rotation-stopping member 10 can also protrude from the lower portion of the first receiving portion 8. The user can clearly determine the upright / inverted state of the cup 1 according to the length of the portion of the first rotation-stopping member 10 that protrudes from the lower portion of the first receiving portion 8. The user can also prevent the first rotation-stopping member 10 from being latched at a certain position by jiggling the portion of the first rotation-stopping member 10 that protrudes from the lower portion of the first receiving portion 8.

[0044] The above describes the automatic locking structure of the cup cover 2 and the connecting member 4. The present application can also automatically lock the cup body 3 and the connecting member 4.

[0045] As shown in FIG. 1, Figure 3 the connecting member 4 is provided with a fourth receiving portion 14, and the cup body 3 is provided with a third receiving portion 13. When the connecting member 4 and the cup body 3 are screwed together, the fourth receiving portion 14 and the third receiving portion 13 are opposite and communicate in the up-down direction,

[0046] As shown in FIG. 1, Figure 3 the cup 1 further includes a second rotation-stopping member 12 for limiting the relative rotation between the cup body 3 and the connecting member 4 in the inverted state of the cup. The second rotation-stopping member 12 is received in the third receiving portion 13, and is movably installed in the third receiving portion 13.

[0047] The length of the second rotation-stopping member 12 in the up-down direction is smaller than the length of the third receiving portion 13 in the up-down direction, so that when the cup 1 is right-side-up, the second rotation-stopping member 12 is entirely received in the third receiving portion 13, and when the cup 1 is upside-down, the second rotation-stopping member 12 slides downward. Since the fourth receiving portion 14 is opposite to and communicates with the third receiving portion 13 in the up-down direction, a part of the second rotation-stopping member 12 can slide into the fourth receiving portion 14. The length of the second rotation-stopping member 12 in the up-down direction is greater than the length of the fourth receiving portion 14 in the up-down direction, so that the second rotation-stopping member 12 cannot slide entirely into the fourth receiving portion 14. A part of the second rotation-stopping member 12 enters the fourth receiving portion 14 and another part of the second rotation-stopping member 12 remains in the third receiving portion 13. That is, the second rotation-stopping member 12 enters the fourth receiving portion 14 while being received in the third receiving portion 13.

[0048] Since the second rotation-stopping member 12 is located in both the fourth receiving portion 14 (provided in the connecting member 4) and the third receiving portion 13 (provided in the cup body 3) when the cup 1 is upside-down, the second rotation-stopping member 12 functions as a latch at this time, and is latched at the connecting portion of the cup body 3 and the connecting member 4, so that the cup body 3 cannot rotate relative to the connecting member 4. Therefore, the user cannot unscrew the cup body 3 from the connecting member 4 at this time. Thus, the user can be prevented from mistakenly unscrewing the cup body 3 from the connecting member 4 when the cup 1 is upside-down.

[0049] The cross-sectional area of each of the third receiving portion 13 and the fourth receiving portion 14 can be greater than the cross-sectional area of the second rotation-stopping member 12, so that the second rotation-stopping member 12 can slide in the third receiving portion 13 and the fourth receiving portion 14 in a freely movable manner. When the cup 1 is right-side-up, the second rotation-stopping member 12 is entirely received in the third receiving portion 13, and at this time, the second rotation-stopping member 12 is not located at the connecting portion of the cup body 3 and the connecting member 4, so that the user can unscrew the cup body 3 from the connecting member 4. When the cup 1 is upside-down, the second rotation-stopping member 12 slides downward with the cup 1, and enters the fourth receiving portion 14 while being received in the third receiving portion 13, so that the cup body 3 cannot rotate relative to the connecting member 4, and the user cannot unscrew the cup body 3 from the connecting member 4.

[0050] Thus, the automatic locking member 5 can also prevent the user from mistakenly unscrewing the cup body 3 from the connecting member 4 when the cup 1 is upside-down. That is, the automatic locking member 5 described above can prevent both the cup cover 2 and the cup body 3 from being mistakenly unscrewed from the connecting member 4. However, the automatic locking member 5 can prevent only the cup cover 2 or only the cup body 3 from being mistakenly unscrewed from the connecting member 4.

[0051] As described above, the connecting member 4 has the first receiving portion 8 and the fourth receiving portion 14. Here, either the first receiving portion 8 and the fourth receiving portion 14 can be independent of each other, or the first receiving portion 8 can pass through the connecting member 4 in the up-down direction, and a portion of the first receiving portion 8 below the first rotation-stopping member 10 can be regarded as the fourth receiving portion 14. That is, the connecting member 4 has only the first receiving portion 8, and a portion of the first receiving portion 8 below the first rotation-stopping member 10 can be regarded as the fourth receiving portion 14. In this case, the first receiving portion 8, the second receiving portion 7, and the third receiving portion 13 are continuous.

[0052] When the cup 1 is right-side up, the first receiving portion 8 does not enter the third receiving portion 13. For example, the first receiving portion 8 can be prevented from entering the third receiving portion 13 by making the cross-sectional area of the first receiving portion 8 larger than the cross-sectional area of the third receiving portion 13. The first receiving portion 8 can also be prevented from entering the third receiving portion 13 by making the protruding portion 11 be engaged with one end of the long hole 9. Further, when the cup 1 is right-side up, a portion of the first receiving portion 8 below the first rotation-stopping member 10 can be regarded as the fourth receiving portion 14. Alternatively, when the cup 1 is right-side up, a portion of the first receiving portion 8 below the first rotation-stopping member 10 can not exist, but even in this case, when the cup 1 is inverted, the first rotation-stopping member 10 moves with the inversion of the cup 1, and thus a space is created after the movement as the fourth receiving portion 14. Both of the above cases belong to the case where "a portion of the first receiving portion 8 below the first rotation-stopping member 10 is regarded as the fourth receiving portion 14".

[0053] <Modified Example>

[0054] The above describes the structure having the cup cover 2, the cup body 3, and the connecting member 4, but the present application can not have the connecting member 4. That is, the present application can have only the cup cover 2 and the cup body 3.

[0055] In Figure 4 , a schematic view of the cup 1' having only the cup cover 2 and the cup body 3 is shown, Figure 5 , a B-B cross-sectional view through the automatic locking member 5' is shown, and Figure 5 , a structure observed from the angle of view of the B-B cross-sectional view is shown.

[0056] As shown in Figure 5 , compared with the structure in Figure 3 , the structure in Figure 5 omits the connecting member 4, and the cup 1' includes the cup body 3 having an open upper end, and the cup cover 2 having an open lower end and being threadedly connected to the cup body 3 in a detachable manner. The automatic locking member 5' has the first receiving portion 8 and the second receiving portion 7. The first receiving portion 8 is provided to the cup body 3, and the second receiving portion 7 is provided to the cup cover 2.

[0057] As shown in Figure 5 , a first receiving portion 8 is arranged in the cup body 3, a second receiving portion 7 is arranged in the cup cover 2, when the cup cover 2 and the cup body 3 are screwed together, the second receiving portion 7 and the first receiving portion 8 are opposite and communicated in the up-down direction, a first rotation-stopping member 10 is received in the first receiving portion 8, the first rotation-stopping member 10 is movably installed in the first receiving portion 8, and the first rotation-stopping member 10 is used to limit the relative rotation between the cup cover 2 and the cup body 3 in the inverted state of the cup set.

[0058] The length of the first rotation-stopping member 10 in the up-down direction is less than the length of the first receiving portion 8 in the up-down direction, so that the first rotation-stopping member 10 is entirely received in the first receiving portion 8 in the state shown in Figure 5 . When the cup set is inverted, the first rotation-stopping member 10 slides downward, since the second receiving portion 7 and the first receiving portion 8 are opposite and communicated in the up-down direction, part of the first rotation-stopping member 10 can slide into the second receiving portion 7, the length of the first rotation-stopping member 10 in the up-down direction is greater than the length of the second receiving portion 7 in the up-down direction, so that the first rotation-stopping member 10 cannot slide entirely into the second receiving portion 7, part of the first rotation-stopping member 10 enters the second receiving portion 7 and the other part of the first rotation-stopping member 10 is still in the first receiving portion 8. That is, the first rotation-stopping member 10 enters the second receiving portion 7 while being received in the first receiving portion 8.

[0059] Since the first rotation-stopping member 10 is located in the first receiving portion 8 (arranged in the cup body 3) and the second receiving portion 7 (arranged in the cup cover 2) at the same time when the cup set 1 is inverted, the first rotation-stopping member 10 at this time plays the role of a latch, is clamped at the connection of the cup cover 2 and the cup body 3, so that the cup cover 2 cannot rotate relative to the cup body 3, and the user cannot unscrew the cup cover 2 from the cup body 3 at this time. Thus, it can be prevented that the user mistakenly unscrews the cup cover 2 in the case that the cup set 1 is inverted.

[0060] It can be that the cross-sectional area of both the first receiving portion 8 and the second receiving portion 7 is greater than the cross-sectional area of the first rotation-stopping member 10, so that the first rotation-stopping member 10 can slide in the first receiving portion 8 and the second receiving portion 7 in a movable manner. When the cup set 1 is placed upright, the first rotation-stopping member 10 is entirely received in the first receiving portion 8, at this time, the first rotation-stopping member 10 is not located at the connection of the cup cover 2 and the cup body 3, so it will not hinder the user from unscrewing the cup cover 2 from the cup body 3. When the cup set 1 is inverted, the first rotation-stopping member 10 slides downward with the inversion of the cup set 1, enters the second receiving portion 7 while being received in the first receiving portion 8, so that the cup cover 2 cannot rotate relative to the cup body 3, hindering the user from unscrewing the cup cover 2 from the cup body 3.

[0061] It can also be that, as shown in Figure 5As shown, a part of the first rotation stopping member 10 protrudes from the first receiving portion 8. Thus, a user can determine whether the cup 1 is in a right position or upside down according to the protruding part of the first rotation stopping member 10, and if the first rotation stopping member 10 is unexpectedly stuck somewhere and cannot move with the cup 1 being righted or upside down, the user can move the first rotation stopping member 10 by pushing the protruding part of the first rotation stopping member 10 to release the stuck state of the first rotation stopping member 10.

[0062] Preferably, the second receiving portion 7 is fixed with a magnet 6, and the first rotation stopping member 10 is made of a material that can be attracted by the magnet 6. When the first rotation stopping member 10 enters the second receiving portion 7, the magnet 6 contacts the first rotation stopping member 10, thus the first rotation stopping member 10 can be magnetically attracted to the magnet 6 to keep the first rotation stopping member 10 in the second receiving portion 7. In this case, the first receiving portion 8 is formed on the outer circumferential surface of the connecting member 4, a long hole 9 is formed on the outer circumferential surface of the first receiving portion 8, and an extending part 11 is formed on the first rotation stopping member 10, which protrudes from the long hole 9.

[0063] Thus, when the cup 1 is upside down, the first rotation stopping member 10 slides to the second receiving portion 7 and is magnetically attracted to the magnet 6, and the extending part 11 slides in the long hole 9 and stops somewhere. A user can clearly determine the state of the cup 1 according to the position of the extending part 11, and the first rotation stopping member 10 reliably functions as a latch to prevent the user from mistakenly opening the cup cover 2. When the user wants to open the cup cover 2, the user rightens the cup 1 and pushes the extending part 11 to slide the first rotation stopping member 10 back to the first receiving portion 8 to release the stuck state.

[0064] As to the structure that a part of the first rotation stopping member 10 protrudes from the first receiving portion 8, it is not limited to the structure that the extending part 11 protrudes from the long hole 9. The first rotation stopping member 10 can protrude from below the first receiving portion 8. A user can clearly determine the righting or upside down state of the cup 1 according to the length of the part of the first rotation stopping member 10 protruding from below the first receiving portion 8, and can prevent the first rotation stopping member 10 from being stuck somewhere by pushing the part of the first rotation stopping member 10 protruding from below the first receiving portion 8.
