DETAILED DESCRIPTION

[0036] The following description is intended to disclose the present invention and enable those skilled in the art to implement the present invention. The preferred embodiments described below are provided for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention as defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0037] First embodiment

[0038] like Figure 1 and Figure 2 As shown, the cup cover 100 includes:

[0039] The upper cover 110 includes an inner ring 111. The outer side surface of the inner ring 111 is recessed to form a guide slide 111a and a guide opening 111b. The guide slide 111a is provided with a latch 111a1. The latch 111a1 and the guide opening 111b are staggered along the circumferential direction of the inner ring 111. The guide opening 111b is connected to the guide slide 111a and is exposed on the axial lower side of the inner ring 111.

[0040] The lower cover 120 has an inner wall provided with a guide protrusion 120a, and the guide protrusion 120a enters the guide slide 111a from the guide opening 110b. After the upper cover 110 and the lower cover 120 rotate relative to each other, the guide protrusion 120a cooperates with the locking position 110a1 of the guide slide 110a.

[0041] The guide protrusion 120a of the lower cover 120 slides into the guide slide 110a through the guide opening 110b, and then the lower cover 120 or the upper cover inner ring 111 is rotated to engage the guide protrusion 120a of the lower cover 120 with the locking position 110a1 of the guide slide 110a. Since the locking position 111a1 and the guide opening 111b are staggered along the circumferential direction of the upper cover inner ring 111, and the guide protrusion 120a is engaged with the locking position 110a1, the lower cover 120 will not shift relative to the upper cover inner ring 111. This not only simplifies the structure and reduces costs, but also facilitates and quickly assembles, and the assembled cup cover 100 has a stable structure.

[0042] like Figure 1 、 Figure 3 and Figure 4 As shown, the upper cover inner ring 111 includes:

[0043] Upper cover plate 1111;

[0044] The upper cover lower plate 1112 , the guide slide 111 a is formed between the upper cover lower plate 1112 and the upper cover upper plate 1111 , and a guide opening 111 b is opened on the upper cover lower plate 1112 .

[0045] The upper cover upper plate 1111 and the upper cover lower plate 1112 are both annular, and the guide slide 111a is formed between the upper cover lower plate 1112 and the upper cover upper plate 1111. The guide slide 111a is exposed on the outer side of the upper cover inner ring 111 so that the lower cover 120 can be assembled on the outer side of the upper cover inner ring 111, and the guide protrusion 120a on the inner wall of the lower cover 120 can slide in the guide slide 111a formed between the upper cover upper plate 1111 and the upper cover lower plate 1112.

[0046] The guide opening 111b passes through the upper cover lower plate 1112, and the bottom of the guide opening 111b is flush with the bottom of the guide slide 111a, so that the guide protrusion 120a can slide smoothly from the guide opening 111b into the guide slide 111a.

[0047] refer to Figure 4 As described in 5, the guide opening 111b and the guide protrusion 120a are adapted in shape, wherein the guide opening 111b and the guide protrusion 120a are both fan-shaped. Preferably, the circumference of the guide opening 111b is slightly larger than the circumference of the guide protrusion 120a, so that the guide protrusion 120a can pass through the guide opening 111b.

[0048] like Figure 3 As shown, the upper cover inner ring 111 also includes:

[0049] The upper cover inner plate 1115 is connected to the inner edge of the upper cover upper plate 1111 and the inner edge of the upper cover lower plate 1112 respectively.

[0050] The upper cover inner plate 1115 is annular and is used to connect the upper cover upper plate 1111 and the upper cover lower plate 1112. The outer surface of the upper cover inner plate 1115 is convex and serves as the bottom of the guide opening 111b and the guide slide 111a. It can be seen that the guide slide 111a is annular.

[0051] like Figure 1 and Figure 3 As shown, the latching position 111a1 and the guide opening 111b are staggered along the circumferential direction of the upper cover inner ring 111, so that after the guide protrusion 120a cooperates with the latching position 111a1, the guide protrusion 120a is not easy to slide out from the guide opening 111b, thereby improving the stability of the structure after assembly.

[0052] refer to Figure 3 , the upper cover inner ring 111 also includes:

[0053] The locking protrusion 1113 is arranged on the upper cover lower plate 1112 where the locking position 111a1 is located, so that the locking position 111a1 is formed between the locking protrusion 1113 and the upper cover upper plate 1111, that is, the guide protrusion 120a abuts between the locking protrusion 1113 and the upper cover upper plate 1111, and at this time the guide protrusion 120a and the locking protrusion 1113 cooperate.

[0054] The locking protrusion 1113 is formed in a raised manner on the upper cover lower plate 1112 where the locking position 111a1 is located. The locking protrusion 1113 can be arched to facilitate the guide protrusion 120a to slide between the locking protrusion 1113 and the upper cover upper plate 1111. When the guide protrusion 120a slides to the highest point of the locking protrusion 1113, the guide protrusion 120a and the locking position 111a1 are interference fit to further improve the connection strength.

[0055] like Figure 1 、 Figure 2 、 Figure 5 As shown, the lower cover 120 includes:

[0056] The lower cover side plate 121 and the inner wall of the lower cover side plate 122 are provided with a guide protrusion 120a.

[0057] The lower cover side plate 121 is annular. After the guide protrusion 120a is aligned with the guide opening 111b, the lower cover side plate 121 moves upward from the axial lower side of the upper cover inner ring 111 to allow the guide protrusion 120a to pass through the guide opening 111b and slide into the guide slide 111a. When the lower cover side plate 121 rotates relative to the upper cover inner ring 111, the lower cover side plate 121 always remains outside the upper cover inner ring 111.

[0058] refer to Figure 3 and Figure 5 The number of guide openings 111b and guide protrusions 120a is equal and corresponds to each other. By increasing the number of guide protrusions 120a, the structure of the lower cover side plate 121 and the upper cover inner ring 111 is more stable after relative rotation and assembly, preventing the two from loosening or detaching after connection.

[0059] There are three guide protrusions 120 a , which are equidistantly spaced along the circumference of the lower cover 120 . In this case, there are also three guide openings 111 b and three latching positions 111 a 1 .

[0060] It should be noted that the number of the guide slide 111 a can be one, that is, the three guide protrusions 120 a slide on the same guide slide 111 a and cooperate with their respective locking positions 111 a 1 .

[0061] Of course, the number of the guide slideways 111a can be equal to the number of the guide openings 111b, and they correspond one to one.

[0062] Specifically, refer to Figure 3 , the upper cover inner ring 111 also includes:

[0063] The barrier member 1114 connects the upper cover upper plate 1111 and the upper cover lower plate 1112 , and a guide slide 111 a is defined between two adjacent barrier members 1114 .

[0064] refer to Figure 2 When looking down at the inner ring 111 of the upper cover, the guide opening 111b and the locking position 111a1 of each group are arranged in a clockwise direction. In this way, when the guide protrusion 120a of the lower cover 120 passes through the guide opening 111b of the inner ring 111 of the upper cover and slides into the guide slide 111a, the lower cover 120 is rotated clockwise to make the guide protrusion 120a of the lower cover 120 slide to the locking position 111a1 of the guide slide 111a to achieve engagement.

[0065] like Figure 2 As shown, the lower cover 120 further includes:

[0066] The lower cover bottom plate 122 has an upper side connected to the lower cover side plate 121 . A rotating protrusion 123 is provided on the lower side of the lower cover bottom plate 122 . A sealing ring 130 is provided on the outer periphery of the rotating protrusion 123 .

[0067] The bottom plate 122 of the lower cover is circular, and a user can act on the rotating protrusion 123 to drive the lower cover 120 to rotate relative to the upper cover inner ring 111, thereby facilitating the rotation of the lower cover 120 relative to the upper cover inner ring 111. When the cup cover 100 is assembled with the cup body, the sealing ring 130 is located inside the cup mouth of the cup body to improve the sealing performance.

[0068] Furthermore, the size of the rotating protrusion 123 is slightly smaller than that of the lower cover side plate 121, so that the sealing ring 130 is clamped on the outer periphery of the rotating protrusion 123, so that the outer side surface of the sealing ring 130 and the outer side surface of the lower cover side plate 121 are roughly flush, and can be adapted to the inner wall of the cup mouth of the cup body together. Figure 1 The rotating protrusion 123 and the sealing ring 130 are snap-connected, for example, the rotating protrusion 123 and the sealing ring 130 are connected by a slot or a block, wherein the sealing ring 130 is made of silicone, rubber or other materials.

[0069] refer to Figure 2 Two action holes 123a are provided on the lower side of the rotating protrusion 123, and an action rod 123b is provided between the two action holes 123a.

[0070] The user can insert the thumb and index finger into the two action holes 123a respectively, and act on the action rod 123b to drive the lower cover 120 to rotate, which is convenient for user operation.

[0071] like Figure 1 and Figure 2 As shown, the upper cover 110 further includes an upper cover outer ring 112, and the upper cover outer ring 112 includes:

[0072] An outer ring bottom plate 1121, the outer ring bottom plate 1121 is connected to the upper cover upper plate 1111 of the upper cover inner ring 111;

[0073] The outer ring side plate 1122 and the upper cover inner ring 111 are respectively connected to the lower side of the outer ring bottom plate 112, the outer ring side plate 1122 is located outside the upper cover inner ring 111, and the inner wall of the outer ring side plate 1122 is provided with an internal thread 1122a.

[0074] The size of the upper cover upper plate 1111 is larger than that of the upper cover lower plate 1112 , so that a structure for clamping is provided on the upper cover upper plate 1111 to be clamped with the outer ring bottom plate 1121 .

[0075] The upper end of the outer ring side plate 1122 is connected to the outer ring bottom plate 1121, and the lower end of the outer ring side plate 1122 extends beyond the bottom surface of the lower cover 120. The mouth of the cup body is inserted between the lower cover 120 and the outer ring side plate 1122, and the mouth of the cup body is screwed to the internal thread 1122a on the inner wall of the outer ring side plate 1122.

[0076] The upper cover inner ring 111 can be first assembled with the upper cover outer ring 112 to form the upper cover 110, and then assembled with the lower cover 120, or the upper cover inner ring 111 can be first assembled with the lower cover 120, and then assembled as a whole with the upper cover outer ring 112. The following only takes the assembly of the upper cover inner ring 111 and the lower cover 120 as an example to introduce the assembly process of the two:

[0077] First, align the guide protrusion 120a of the lower cover 120 with the guide opening 111b on the axially lower side of the inner ring 111 of the upper cover;

[0078] Then, the guide protrusion 120a of the lower cover 120 is slid into the guide slide 110a through the guide opening 110b. At this time, the lower cover 120 is located outside the inner ring 111 of the upper cover.

[0079] Then, the lower cover 120 or the upper cover inner ring 111 is rotated so that the guide protrusion 120 a of the lower cover 120 is engaged with the latching position 110 a 1 of the guide slide 110 a , thereby assembling the cup cover 100 .

[0080] It can be seen that the assembly can be completed by relative rotation of the lower cover 120 and the upper cover inner ring 111 until the guide protrusion 120a of the lower cover 120 is matched with the locking position 110a1 of the guide slide 110a. The assembly is convenient and quick, and the structure is simplified and the cost is reduced. In addition, by reverse rotation of the lower cover 120 or the upper cover inner ring 111, the two can be disassembled, which can achieve the purpose of easy cleaning.

[0081] In addition, the lower cover 120 and the upper cover inner ring 111 can be

[0088] Since the cup includes the cup cover 100 , the beneficial effects of the cup can refer to the cup cover 100 of the above embodiment.

[0089] The cup also includes a cup body, which has a cup mouth. The cup mouth of the cup body is inserted between the lower cover 120 and the outer ring side plate 1122. The cup mouth of the cup body is screwed to the internal thread 1122a on the inner wall of the outer ring side plate 1122 to realize the assembly of the cup cover 100 and the cup body. After rotating the cup cover 100 in the opposite direction, the cup cover 100 can be disassembled relative to the cup body to open the cup mouth of the cup body for the user to drink.

[0090] The embodiments described above are only used to illustrate the technical ideas and features of the present invention.
