Description

Technical Field

[0001] This invention relates to the field of oral liquid packaging container technology, and in particular to an oral liquid bottle. Background Technology

[0002] Currently, the caps of oral liquid bottles on the market are difficult to open, making them cumbersome and providing a poor user experience. They are all pre-filled mixed liquids that can be consumed directly after opening the cap, which makes it difficult to solve the problem of adding powdered or concentrated medications before consumption. Furthermore, the state of some powdered or concentrated medications becomes unstable after being mixed with oral liquids, and their shelf life is significantly shortened.

[0003] With technological advancements, bottle containers for storing solid powders or concentrated liquids with water have gradually emerged. See Chinese patent document CN107284838A, which discloses a bottle cap including a lower cap and an upper cap connected to the lower cap. The upper cap has a storage chamber for storing solid powders or concentrated liquids, with an opening at the lower end and a sealing film at the opening. The lower cap includes an upper connecting part and a lower connecting part. The outer wall of the upper connecting part has external threads, and the inner wall of the upper cap has internal threads that mate with the external threads. The lower end of the upper cap has an anti-counterfeiting limiting ring that prevents the upper cap from moving downwards relative to the lower cap. The lower connecting part has a piercing element that, when the anti-counterfeiting limiting ring is removed from the upper cap, rotating the upper cap causes it to move downwards relative to the lower cap, thereby piercing the internal sealing film and allowing the solid powders or concentrated liquids in the storage chamber to mix smoothly with the solution inside the bottle. However, the patent document CN107284838A still has the following technical problems: (1) During the puncture process, the sealing film may still produce debris that falls into the solution inside the bottle; (2) When the puncturing part punctures the sealing film upwards, it is easy to block the puncture opening of the sealing film, so that when the solid powder or concentrated liquid in the storage chamber falls from the puncture opening, it is easy to be blocked by the puncturing part and difficult to fall into the bottle. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to address the shortcomings of the prior art by providing an oral liquid bottle that can separately hold powdered or concentrated drugs and oral liquid. The drug can be dropped from the drug-containing cavity into the bottle body by rotating the inner stopper cap, allowing the drug to mix with the oral liquid, making it convenient to use. Furthermore, the oral liquid bottle uses the bottom of the inner stopper rod of the inner stopper cap to seal the drug outlet, or the drug outlet can be pulled out to connect the drug-containing cavity with the bottle body, eliminating the need for a sealing film and puncture device. Pulling the bottom of the inner stopper rod of the inner stopper cap out of the drug outlet allows the drug outlet to be fully opened, preventing blockage and allowing the drug in the drug-containing cavity to easily fall into the bottle body. Alternatively, the oral liquid bottle can be inverted to allow the oral liquid inside the bottle to flow back from the drug outlet into the drug-containing cavity to mix with the drug, and then the bottle can be inverted back and placed upright to allow the mixed oral liquid to flow back into the bottle body from the drug-containing cavity through the drug outlet.

[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is: an oral liquid bottle, comprising: The bottle body contains an oral liquid, and the upper end of the bottle body is provided with a bottle body connecting part.

The inner cap includes a rotating cylinder and an inner plug rod. The top end of the rotating cylinder and the top end of the inner plug rod are integrally connected. A second annular cavity is provided between the upper part of the rotating cylinder and the inner plug rod. The outer wall of the rotating cylinder is provided with an outwardly protruding protrusion. The rotating cylinder can rotatably extend into the first annular cavity. The protrusion extends into the inclined guide hole and can move along the inclined guide hole. The upper part of the inner cylinder can rotatably extend into the second annular cavity. The inner plug rod is inserted into the drug receiving cavity of the inner cylinder. The bottom of the inner plug rod can be inserted into the drug outlet hole and block the drug outlet hole, or pulled out from the drug outlet hole, so that the drug receiving cavity is connected to the bottle body.

[0006] Preferably, the bottle body connecting part is provided with external thread, the lower part of the outer cylinder of the lower screw cap is provided with internal thread, a third annular cavity is provided between the lower part of the outer cylinder and the inner cylinder, the bottle body connecting part extends into the third annular cavity, and the external thread of the bottle body connecting part is threadedly connected to the internal thread of the inner cylinder.

[0007] Preferably, the connection between the middle part of the outer cylinder and the middle part of the inner cylinder has an annular connecting ring, which isolates the first annular cavity from the third annular cavity.

[0008] Preferably, the upper part of the outer cylinder has two oblique guide holes with opposite positions, and the outer wall of the rotating cylinder has two protrusions corresponding to the oblique guide holes; the upper inner wall of the outer cylinder has two assembly notches corresponding to the oblique guide holes, and the lower end of the assembly notch has a guide slope, so that the protrusion can slide through the assembly notch and the guide slope and be assembled into the oblique guide hole.

[0009] Preferably, the upper outer wall of the inner plug rod is provided with a sealing ring, and the outer side of the sealing ring contacts and is interference-fitted with the upper inner wall of the inner cylinder. Further, the sealing ring is integrally connected to the upper outer wall of the inner plug rod, and the number of sealing rings is 2-5, with the 2-5 sealing rings spaced apart from each other.

[0010] Preferably, the lower part of the inner plug rod is smaller than the upper part of the inner plug rod, and there is a space for accommodating the drug between the lower part of the inner plug rod and the inner wall of the drug receiving cavity.

[0011] Preferably, the oral liquid bottle further includes an upper screw cap, which closes to the upper end of the inner stopper cap, and the outer side of the upper screw cap is provided with a ring of anti-slip texture; the inner stopper cap has a central hole axially provided in the middle of the inner stopper rod, the lower end of the central hole is closed and the upper end is open. The wall thickness of the central hole is uniform, the upper end of the inner stopper cap is provided with a ring of vertical outer grooves, and the inner wall of the upper screw cap is provided with a ring of vertical inner grooves, the outer grooves and the inner grooves interlocking with each other.

[0022] The structural and working principles of the present invention will be further described in detail below with reference to the accompanying drawings.

[0023] like Figure 1-8 As shown, the present invention provides an oral liquid bottle comprising a bottle body 1, a lower screw cap 2, and an inner stopper cap 3; the bottle body 1 is used to contain oral liquid, and the upper end of the bottle body 1 is provided with a bottle body connecting part 11; the lower screw cap 2 comprises an outer cylinder 21 and an inner cylinder 22, the outer cylinder 21 is fitted over the inner cylinder 22, the middle part of the outer cylinder 21 is integrally connected to the middle part of the inner cylinder 22, the lower part of the outer cylinder 21 is detachably connected to the bottle body connecting part 11, a first annular cavity 24 is provided between the upper part of the outer cylinder 21 and the inner cylinder 22, and an oblique guide hole 25 penetrating through the inner and outer sides is provided on the upper part of the outer cylinder 21; the inner cylinder 22 contains a drug receiving cavity 26, and the bottom end of the drug receiving cavity 26 is provided with a drug outlet 27; the inner stopper cap 3 comprises a rotating cylinder 31 and a... The inner stopper rod 32 is integrally connected to the top end of the rotating cylinder 31. A second annular cavity 33 is provided between the upper part of the rotating cylinder 31 and the inner stopper rod 32. The outer wall of the rotating cylinder 31 is provided with an outwardly protruding protrusion 34. The rotating cylinder 31 can rotatably extend into the first annular cavity 24. The protrusion 34 extends into the inclined guide hole 25 and can move along the inclined guide hole 25. The upper part of the inner cylinder 22 can rotatably extend into the second annular cavity 33. The inner stopper rod 32 is inserted into the drug receiving cavity 26 of the inner cylinder 22. The bottom of the inner stopper rod 32 can be inserted into the drug outlet hole 27 and block the drug outlet hole 27, or be pulled out from the drug outlet hole 27, so that the drug receiving cavity 26 is connected to the bottle body 1.

[0024] The bottle body 1 of this invention can be filled with oral liquid, and the drug receiving cavity 26 inside the inner cylinder 22 of the lower screw cap 2 can be filled with powdered drug or concentrated drug, thereby enabling the invention to separately store powdered drug or concentrated drug and oral liquid; by rotating the inner stopper cap 3, the protrusion 34 can move along the inclined guide hole 25, thereby pushing the inner stopper cap 3 to rise or fall; when the protrusion 34 is at the lowest position of the inclined guide hole 25, the bottom of the inner stopper rod 32 of the inner stopper cap 3 is inserted into the drug outlet hole 27 and blocks the drug outlet hole 27, and the drug outlet hole 27 is in a closed state (see Figure 2The powdered or concentrated medication within the drug receiving cavity 26 is isolated from the oral liquid within the bottle 1, preventing the powdered or concentrated medication within the drug receiving cavity 26 from falling into the bottle 1. When the inner stopper 3 is rotated and the protrusion 34 moves upward along the inclined guide hole 25, the inner stopper 3 is pushed upward, opening the drug outlet 27. The bottom of the inner stopper rod 32 of the inner stopper 3 is then pulled out of the drug outlet 27, connecting the drug receiving cavity 26 with the bottle 1 (see [link]). Figure 8 This allows the medication to fall from the medication receiving cavity 26 into the bottle body 1, mixing with the oral liquid for convenient use. The invention utilizes the bottom of the inner stopper rod 32 of the inner stopper cap 3 to seal the medication outlet 27, or to remove the inner stopper rod 32 from the medication outlet 27 to connect the medication receiving cavity 26 with the bottle body 1. This eliminates the need for a sealing film and puncture devices. After the bottom of the inner stopper rod 32 is removed from the medication outlet 27, the outlet 27 is fully opened, preventing blockage and allowing the medication in the medication receiving cavity 26 to easily fall into the bottle. Inside the body 1; or the oral liquid bottle can be turned upside down so that the body 1 faces upwards, allowing the oral liquid inside the body 1 to flow back from the drug outlet 27 into the drug receiving cavity 26 to mix with the drug. During this process, the bottle can be shaken several times to ensure that the drug and oral liquid are fully mixed. Then the oral liquid bottle is turned upside down and placed upright so that the bottle faces downwards, allowing the mixed oral liquid to flow back into the body 1 from the drug receiving cavity 26 through the drug outlet 27. Finally, the user can unscrew the lower cap 2 from the top of the body 1 to open and then take the oral liquid inside the bottle.

[0025] like Figure 2 , Figure 4 , Figure 6 and Figure 8 As shown, the bottle body 1 has an external thread on its connecting part 11, and the lower part of the outer cylinder 21 of the lower cap 2 has an internal thread. A third annular cavity 28 is provided between the lower part of the outer cylinder 21 and the inner cylinder 22. The bottle body connecting part 11 extends into the third annular cavity 28, and the external thread of the bottle body connecting part 11 is threadedly connected to the internal thread of the inner cylinder 22. An annular connecting ring 23 is provided at the connection between the middle of the outer cylinder 21 and the middle of the inner cylinder 22. The annular connecting ring 23 isolates the first annular cavity 24 and the third annular cavity 28 from each other. After the bottle body connecting part 11 extends into the third annular cavity 28 and connects with the lower part of the outer cylinder 21, the annular connecting ring 23 can still provide a good sealing effect.

[0026] like Figure 1 , Figure 2 , Figures 4-8As shown, the upper part of the outer cylinder 21 has two oblique guide holes 25 with opposite positions, and the outer wall of the rotating cylinder 31 has two protrusions 34 corresponding to the oblique guide holes 25; the upper inner wall of the outer cylinder 21 has two assembly notches 29 corresponding to the oblique guide holes 25, and the lower end of the assembly notch 29 has a guide slope 291. The protrusions 34 can slide through the assembly notch 29, pass through the guide slope 291, and be assembled into the oblique guide hole 25. When installing the inner plug 3, first insert the inner plug 3 into the inner cylinder 22 of the lower screw cap 2; then align the protrusions 34 of the inner plug 3 with the assembly notches 29 on the outer cylinder 21 of the lower screw cap 2; then, press the inner plug 3 down with a little force, so that the protrusions 34 of the inner plug 3 push down to open the outer cylinder 21, slide through the guide slope 291, and be assembled into the oblique guide hole 25. The assembly is convenient.

[0027] like Figure 2 , Figure 3 and Figure 8 As shown, a sealing ring 35 is provided on the upper outer wall of the inner plug rod 32. The outer side of the sealing ring 35 contacts and is press-fitted with the upper inner wall of the inner cylinder 22. Under the action of the sealing ring 35, the upper end of the drug receiving cavity 26 can be sealed, preventing powdered or concentrated drugs from escaping from the gap between the inner plug rod 32 and the inner cylinder 22, and preventing outside air from entering the drug receiving cavity 26 from the gap between the inner plug rod 32 and the inner cylinder 22. Preferably, the sealing ring 35 is integrally connected to the upper outer wall of the inner plug rod 32, and the number of sealing rings 35 is 2-5, spaced apart from each other, achieving a very good sealing effect. More preferably, the number of sealing rings 35 is 3.

[0028] like Figure 2 , Figure 4 , Figure 6 and Figure 8 As shown, the lower part of the inner plug rod 32 is smaller than the upper part of the inner plug rod 32, and there is a space for accommodating drugs between the lower part of the inner plug rod 32 and the inner wall of the drug receiving cavity 26.

[0029] like Figure 1 , Figure 2 , Figure 4 , Figures 6-8As shown, the oral liquid bottle also includes an upper screw cap 4, which covers the upper end of the inner cap 3. The outer side of the upper screw cap 4 has a ring of anti-slip texture 41. The inner cap 3 has an axially oriented central hole 36 in the middle of its inner plug rod 32, with the lower end of the central hole 36 closed and the upper end open. The main purpose of the upper screw cap 4 is to allow the inner cap 3 to be formed into a hollow structure, facilitating injection molding. Furthermore, the wall thickness of the central hole 36 is uniform, and the upper end of the inner cap 3 has a ring of vertical outer grooves 37. The inner wall of the upper screw cap 4 has a ring of vertical inner grooves 42, with the outer grooves 37 and inner grooves 42 interlocking. The advantage of using a hollow structure with uniform hole wall thickness for the inner plug cap 3 is that after injection molding, the surface of the inner plug rod 32 of the inner plug cap 3 is uniform and smooth, and the sealing effect between the inner plug rod 32 and the inner cylinder 22 and the drug outlet 27 is good. However, if a solid inner plug rod 32 is used, it will shrink and deform significantly after molding and cooling, resulting in an uneven appearance and poor sealing.

[0030] As a preferred embodiment of the present invention, the bottle body 1, the lower screw cap 2, the inner plug cap 3, and the upper screw cap 4 are all made of PP material, which has excellent sealing effect, can be recycled, and reduces waste of outer packaging materials.

[0031] The above description is merely a preferred embodiment of the present invention. Any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical solution of the present invention shall fall within the scope of the technical solution of the present invention.
