Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example

[0016] like Figure 1 , 2 The rotary lifting center dispensing bottle device shown in pictures 3, 5, 6, 7, 9, and 10 includes a rotating outer sleeve 1, a sliding inner cover 4, upper and lower center dispensing caps 2, and a bottle body 3. The bottle body 3 has a bottle opening at its upper part, which is threaded onto the sliding inner cover 4. The upper and lower center dispensing caps 2 have sliding posts 5 on both sides of their outer walls, and a dispensing hole 6 in the center. The walls of the upper and lower center dispensing caps 2 include a first wall and a second wall. The outer side wall of the sliding inner cover 4 has a sliding groove 9. The first wall is located inside the outer side wall of the sliding inner cover 4, and the second wall is... Outside the inner sidewall of the inner cover 4, a sliding column 5 is engaged in the sliding groove 9. The sliding groove 9 is a sloped groove. The inner wall of the rotating outer sleeve 1 has a vertical groove 10, in which the sliding column 5 is engaged. An annular body 7 is provided on the outer side of the liquid outlet 6. A plug 8 is provided in the middle of the inner cover 4. The plug 8 and the liquid outlet 6 cooperate, and a slightly tight fit allows for movable sealing. The inner cover 4 has a threaded cap housing that wraps around the bottle mouth. The outer wall of the threaded cap housing is fixedly connected to the bottle mouth by threads, and the inner wall faces downward and contacts the inner wall of the bottle mouth, allowing for movable sealing. Under the action of rotating the outer sleeve 1 and rotating the sliding column 5 vertically up and down, and the interaction with the threaded directional strip, the upper and lower caps 2 of the central liquid outlet move up and down, opening or closing the liquid outlet 6. When open, the amount of liquid or water dispensed can be freely adjusted by inverting the bottle or squeezing the bottle.

[0017] The lower part of the inner wall of the rotating outer sleeve 1 is provided with a threaded guide bar 11, and the top extends inward to form a ring body. The ring body blocks the outer side wall of the inner cover 4 of the slide groove. The lower part of the outer side wall of the inner cover 4 of the slide groove is provided with a convex ring 12, which is located above the threaded guide bar 11.

[0018] The lower diameter of the central liquid outlet cap 2 is larger than the upper diameter, the height of the second wall is smaller than that of the first wall, and the lower part of the inner wall of the annular body 7 is provided with a slope, which can be moved to fit and seal.

[0019] The inner cover 4 of the slide is provided with a boss in the middle, and a three-pronged groove 21 is provided on the inner wall of the boss. The three-pronged groove 21 forms a liquid outlet. The bottom end of the boss is threaded to cover the shell. The outer wall of the plug 8 and the inner wall of the annular body 7 are smooth walls. The lower part of the plug 8 is a groove seat, which is connected to the three-pronged groove 21. The three-pronged groove 21 is evenly distributed. The groove seat and plug in the middle of the three-pronged groove 21 are smooth, with the upper part being smaller and the lower part being larger. When closed, the used liquid is quickly returned.

[0020] The upper wall 13 and lower wall 14 of the inner wall of the second wall are smaller in diameter than the middle wall 19, and are slightly tight-fitting, allowing for movement and precise sealing.

[0021] The slide 9 has a notch at the top, an upper protrusion 24 at the top, and a lower protrusion 23 at the bottom. The upper and lower protrusions 24 and 23 have grooves on their outer sides. The grooves are L-shaped. The movement of the slide column 5, especially with the grooves at the upper and lower protrusions, provides a certain amount of flexible space, reducing hard compression and damage to parts. PET bottles can also be blown and positioned with square blocks.

[0022] The bottle body 3 is a PET bottle.

[0023] The bottle body 3 has a locking block 22 on the lower outer wall of the bottle mouth, and the inner wall of the inner cover 4 has a protrusion 27 and an elastic protrusion 28 on the lower part of the inner wall. The locking block 22 is locked between the protrusion 27 and the elastic protrusion 28. The buckle is convenient and durable and not easy to fall off.

[0024] like Figure 8 , 11 As shown in Figures 14 and 15, during use, the lifting specifications are 6mm and 12mm. The chute crosses the groove at different heights. Simply changing the chute can upgrade the upper and lower caps 2 of the center outlet, modifying them to different heights. The plug 8 and the outlet hole 6 cooperate to seal, completing the first seal. The diameters of the upper wall 13 and lower wall 14 of the inner wall of the second wall are smaller than those of the middle wall. The middle wall 19 is slightly tight-fitting, allowing it to move up and down and also sealing water. In this way, the outer side wall of the inner cover 4 of the chute fits more closely with the upper wall 13 and lower wall 14, with a slightly tight fit, allowing it to move and seal, completing the second seal. The inner and outer side walls of the threaded cap shell complete the third seal with the bottle mouth, sealing the bottle mouth. This greatly improves the sealing effect. When the outer sleeve 1 rotates, the vertical slot 10 squeezes the sliding column 5 to move in the chute, and the upper and lower caps 2 of the center outlet move up and down. After inverting or squeezing the bottle body 3 times, the liquid will be dispensed. After use, rotate to close. The innermost center always maintains a sealed state. This is a PE material extrusion blow bottle, a center-discharge directional bottle. Two types of bottles can be used, mainly bottles made by secondary blow molding of PET preforms. This PE / PP material can be produced by blow molding on an extruder. That is, after the round material tube is extruded, the material tube is automatically closed and then hot-cut. After the mold is closed, it is top-flush and formed. After it comes out, the flash is removed. It has strong versatility and wide applicability. The thickness and material of the bottle can also be adjusted to make the bottle appearance and hardness change to adjust to a suitable softness and hardness. PET, LDPE and HDPE can be mixed and used. The thickness of the bottle is also due to the different materials that produce bottles with different softness and hardness. All of these are for the needs of moderate softness and hardness and quality requirements, so as to facilitate the use of different liquids and achieve better results. Example

[0025] like Figure 13As shown, the difference between this embodiment and embodiment 1 is that the bottle body 3 is a PE bottle, and the bottle mouth clamp is provided with a convex block. There are two symmetrical convex blocks. The outer wall of the convex block extends to the lower ring body, and the ring bodies are connected together. The bottle preform on the shoulder has a ring of blow clamping ring. The key point is that the two convex blocks play a positioning role. The inner cap of the threaded directional sliding groove is tightened and matched for orientation.
