[0027] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0028] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.

[0029] Some embodiments of the present invention are described below with reference to the accompanying drawings.

[0030] Reference Figure 1-8 , a hidden tube cover, including a cover body 1 for connecting to the mouth of a container, the cover body 1 is provided with a liquid outlet pipe 2 for communicating with the inner cavity of the container, and a hidden cavity 3 is provided on the cover body 1 corresponding to the liquid outlet pipe 2, the liquid outlet pipe 2 can be bent and hidden in the hidden cavity 3, which can reduce the space required for storage of the tube cover, making it convenient for storage and transportation. At the same time, the hidden cavity also plays a certain protective role for the liquid outlet pipe, avoiding the phenomenon of being hit by foreign objects when the liquid outlet pipe is bent, thereby extending its service life; an air inlet pipe 4 communicating with the inner cavity of the container is extended upward from the bottom of the hidden cavity 3, and the liquid outlet pipe 2 and the air inlet pipe 4 are blocked when they are bent, completely sealing the container, improving the sealing effect, and reducing the possibility of bacteria breeding.

[0031] The liquid outlet tube 2 consists of a flexible first bending portion and a liquid outlet portion located above the first bending portion. The first bending portion is connected to the cover body 1. The liquid outlet portion can be made of a hard plastic material or can be made of a flexible material consistent with the first bending portion.

[0032] Example 1: A first sealing sheet 5 is provided in the first bending portion. When the liquid outlet pipe 2 is bent normally, the structure of the first bending portion will undergo corresponding bending changes, thereby causing the liquid outlet portion to move toward the hidden cavity 3. The first sealing sheet 5 will follow the changes of the first bending portion and change synchronously (this change is within the design range and belongs to conventional design). At this time, the first sealing sheet 5 will not be damaged. When the liquid outlet pipe 2 is bent in other directions (the bending amplitude is small, only within 10 degrees), the structure of the first bending portion will undergo undesigned structural changes, thereby destroying the connection between the first sealing sheet 5 and the first bending portion, and it can be used normally at this time.

[0033] Example 2: A first sealing sheet 5 is provided in the liquid outlet portion, that is, it is located outside the first bending portion. No matter how the liquid outlet tube 2 is bent, it will not affect the first sealing sheet 5. When used for the first time, it is necessary to use tools (such as chopsticks) to destroy the first sealing sheet 5 before normal use.

[0034] The air inlet pipe 4 is composed of a flexible second bending portion and air inlet portions located at the upper and lower ends of the second bending portion. The air inlet portion located at the lower end of the second bending portion is connected to the cover body 1 .

[0035] The second sealing sheet 6 can be arranged in the second bending portion. When the liquid outlet pipe 2 bends normally, the air inlet pipe 4 bends synchronously, and the bending directions are consistent. When the air inlet pipe 4 bends in other directions, the second sealing sheet 6 is destroyed. In the principle embodiment 1, the principle of the first sealing sheet 5 is the same.

[0036] The second sealing sheet 6 may be disposed in the air inlet portion (it may be the air inlet portion located at the upper end of the second bending portion or the air inlet portion located at the lower end of the second bending portion), and the second sealing sheet 6 may be destroyed by a tool.

[0037] Furthermore, in this product, the first sealing sheet 5 and the second sealing sheet 6 may be destroyed in the following ways: both need to be destroyed by tools (i.e., the sealing sheets are set at positions other than the bend, such as above or below the bend); one of them may be destroyed by tools, and the other may be destroyed when bent in other directions (i.e., one of the sealing sheets is set at a position other than the bend, and the other sealing sheet is set at the bend); or neither of them requires tools to be destroyed (i.e., both sealing sheets are set at the bend).

[0038] Furthermore, the first sealing sheet 5 and the second sealing sheet 6 can be completely arranged in the corresponding bending part, that is, they are completely covered by the bending part. Alternatively, part of the sealing sheet is above the bending part and part of the sealing sheet is below the bending part, that is, the sealing sheet completely passes through the bending part.

[0039] Furthermore, the first sealing sheet 5 and the second sealing sheet 6 can be destroyed when the liquid outlet pipe 2 and the air inlet pipe 4 are bent for the first time, and the liquid outlet pipe 2 and the air inlet pipe 4 are sealed by the bent structure; they can be undamaged when they are bent for the first time, but destroyed when they are moved from the bent state to the vertical state; they can also be undamaged when they are bent for the first time, but destroyed when they are bent again; they can also be undamaged when they are bent for the first time, but destroyed when they are bent in other directions (different from the direction of the first bending).

[0040] like Figure 4 、 6 As shown, the liquid outlet pipe 2 and the air inlet pipe 4 are arranged in the left and right directions. It can be that when the liquid outlet pipe 2 is bent, the outer wall of the liquid outlet pipe 2 pushes the air inlet pipe 4 to bend synchronously; it can also be that the air inlet pipe 4 is manually bent first, and then the liquid outlet pipe 2 is bent.

[0041] Furthermore, the bending directions of the air inlet pipe 4 and the liquid outlet pipe 2 can be the same direction or different directions.

[0042] like Figure 8 As shown in A, the liquid outlet pipe 2 and the air inlet pipe 4 are arranged in the front-to-back direction, and the centers of the liquid outlet pipe 2 and the air inlet pipe 4 can be on the same parallel line (parallel to the side wall of the hidden cavity). Since the diameter of the liquid outlet pipe 2 is larger than the diameter of the air inlet pipe 4, when the cover plate 10 is closed, it will first contact the liquid outlet pipe 2 and then contact the air inlet pipe 4, that is, the liquid outlet pipe 2 is bent first, and then the air inlet pipe 4 is bent; the centers of the liquid outlet pipe 2 and the air inlet pipe 4 may not be on the same parallel line, as shown in FIG. Figure 8 As shown in B, the liquid outlet pipe 2 is closer to the cover plate 10 than the air inlet pipe 4, that is, the liquid outlet pipe 2 is bent first, and the air inlet pipe 4 is bent again; Figure 8 As shown in C, the side walls of the air inlet pipe 4 and the liquid outlet pipe 2 are at the same distance from the cover plate 10, and the air inlet pipe 4 and the liquid outlet pipe 2 are bent at the same time; in addition, the air inlet pipe 4 and the liquid outlet pipe 2 can also adopt other reasonable positional relationships.

[0043] Furthermore, the cover plate 10 can be eliminated from this product. During the production process, the liquid outlet pipe 2 and the air inlet pipe 4 are bent by equipment, and the user can manually bend them.

[0044] When the fluid (including gas and liquid) passes through the air inlet pipe 4, since the channel of the air inlet pipe 4 has a certain length, a certain pressure and flow rate are required to allow the fluid to pass through the air inlet pipe 4. During normal liquid pouring, the liquid pressure and flow rate in the container cannot meet this requirement. The external air has entered the container through the air inlet pipe 4 at the same time as the liquid is discharged, and formed a continuous airflow in the channel of the air inlet pipe 4 (until the pouring is completed), thereby flushing the liquid at the outlet end of the air inlet pipe 4 (such as forming small bubbles one after another), thereby reducing the possibility of liquid being discharged from the air inlet pipe 4 during pouring, and the possibility of blocking the air inlet pipe 4.

[0045] A slot portion 7 is provided at the pipe mouth of the liquid outlet pipe 2 away from the side of the hidden cavity 3, and a first buckle portion 8 is provided on the side wall of the hidden cavity 3 corresponding to the slot portion 7. After the liquid outlet pipe 2 is bent, the first buckle portion 8 is embedded in the slot portion 7; a second buckle portion 9 is provided on the side wall of the hidden cavity 3. After the liquid outlet pipe 2 is bent, the second buckle portion 9 is inserted into the inner side of the liquid outlet pipe 2, and the bottom surface of the second buckle portion 9 is in contact with the inner wall of the liquid outlet pipe 2. When the liquid outlet pipe 2 is bent, the first buckle portion 8 and the second buckle portion 9 limit the movement of the liquid outlet pipe 2, thereby ensuring the stability of the tube cover when it is hidden and making the structure more compact.

[0046] like Figure 7 As shown, gap grooves 13 are provided between the two sides of the first snap-fit portion 8 and the side walls of the hidden cavity 3. On the one hand, this facilitates demolding of the mold, and on the other hand, this increases the flexibility of the first snap-fit portion 8. When in use, the first snap-fit portion 8 is more easily embedded in the slot portion 7 or withdrawn from the slot portion 7.

[0047] A cover plate 10 for covering the hidden cavity 3 is provided on one side of the cover body 1 close to the liquid outlet pipe 2. After the cover plate 10 is lowered, the surface of the cover plate 10 is flush with the surface of the cover body 1, thereby improving the aesthetics of the tube cover; the side wall of the cover plate 10 is provided with a wing portion 11, and an inner recess 12 is provided on the cover body 1 corresponding to the wing portion 11. The wing portion 11 is embedded in the inner recess 12, which is convenient for opening the cover plate 10.
