Technical Field

[0001] This application relates to the field of eye drop bottles, and in particular to an eye drop bottle with a function of preventing the cap from falling off. Background Art

[0002] With the increasing problems of eye diseases and eye fatigue, the market demand for eye drops is growing continuously. As a packaging container that directly contacts the medicine, the design and manufacturing quality of the eye drop bottle are directly related to the safety and convenience of using the medicine.

[0003] Existing eye drop bottles usually use a threaded connection to fix the cap. However, during transportation and use, due to vibration or improper operation by the user, the cap is likely to fall off. Utility Model Content

[0004] In order to improve the problem that the cap of the eye drop bottle is likely to fall off due to vibration during transportation and use, this application provides an eye drop bottle with a function of preventing the cap from falling off.

[0005] An eye drop bottle with a function of preventing the cap from falling off provided by this application adopts the following technical solutions:

[0006] An eye drop bottle with a function of preventing the cap from falling off includes a medicine storage bottle, an inner cap, an outer cap, and a packaging layer. The inner cap is threadedly connected to the medicine storage bottle, the inner cap is in communication with the medicine storage bottle, the outer cap is threadedly connected to the inner cap, and the outer cap closes the inner cap. The packaging layer wraps around the outer walls of the medicine storage bottle and the outer cap, relatively fixing the medicine storage bottle and the outer cap.

[0007] By adopting the above technical solutions, by wrapping the packaging layer on the outer cap and the medicine storage bottle, the outer cap and the medicine storage bottle are relatively fixed. When vibration occurs during transportation or storage, the outer cap and the medicine storage bottle will not rotate relative to each other, thereby preventing the outer cap from falling off and effectively improving the problem that the cap is likely to fall off, ensuring the quality of the eye drops.

[0008] Preferably, an opening dotted line is provided on the packaging layer. The opening dotted line is arranged along the circumferential direction of the packaging layer and is located at the port of the outer cap.

[0009] By adopting the above technical solutions, the packaging layer is easy to open from the opening dotted line, facilitating the tearing of the packaging layer during use.

[0010] Preferably, a plurality of small holes are provided in the packaging layer. The plurality of small holes are arranged at intervals along the circumferential direction of the packaging layer, and the plurality of small holes are connected to form the opening dotted line.

[0011] By adopting the above technical solutions, the structure of the opening dotted line is simple and easy to process.

[0012] Preferably, a ring is provided on the outer wall of the medicine storage bottle. When the outer cap is tightened, the port of the outer cap abuts against the top surface of the ring, and the outer diameter of the ring is greater than the outer diameter of the outer cap.

[0013] By adopting the above technical solution, by providing the ring, the ring is located near the opening dotted line, and the outer diameter of the ring is greater than the outer diameter of the outer cap. Thus, by pressing the packaging layer, the opening dotted line is easily cracked, facilitating the opening of the packaging layer.

[0014] Preferably, multiple protrusions are provided on the surface of the ring that fits with the port of the outer cap, and the protrusions are arranged along the radial direction of the ring; multiple grooves are provided on the port of the outer cap that fits with the ring, and the grooves are arranged corresponding to the protrusions.

[0015] By adopting the above technical solution, by providing the protrusions and the grooves, the friction between the outer cap and the ring can be increased, further avoiding the relative rotation between the outer cap and the medicine storage bottle under non-human force.

[0016] Preferably, a tear strip is provided on the opening dotted line.

[0017] By adopting the above technical solution, by pulling the tear strip, it is easier to crack the packaging layer at the opening dotted line, facilitating the opening of the packaging layer.

[0018] Preferably, an adhesive substance is applied to the inner wall of the packaging layer.

[0019] By adopting the above technical solution, the adhesive substance can further improve the effect of relatively fixing the outer cap and the medicine storage bottle by the packaging layer.

[0020] Preferably, an indicating arrow is marked on the packaging layer, and the direction of the indicating arrow is the direction in which the outer cap is screwed open.

[0021] By adopting the above technical solution, the indicating arrow can clearly indicate the correct opening direction of the bottle cap to the user.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. By wrapping the packaging layer on the outer cap and the medicine storage bottle, the outer cap and the medicine storage bottle are relatively fixed. When vibrations occur during transportation or storage, the outer cap and the medicine storage bottle do not rotate relative to each other, thus avoiding the detachment of the outer cap, effectively improving the problem of easy detachment of the bottle cap, and ensuring the quality of the eye drops;

[0024] 2. The packaging layer is easy to open from the opening dotted line, facilitating the tearing of the packaging layer during use;

[0025] 3. By setting a circular ring such that the circular ring is located near the unsealing dotted line and the outer diameter of the circular ring is greater than the outer diameter of the outer cap, the unsealing dotted line can be easily cracked by pressing the packaging layer, thereby facilitating the opening of the packaging layer.

Detailed Description of the Embodiment

[0031] The following further describes the present application in detail Figures 1-4 with reference to the accompanying drawings.

[0032] An embodiment of the present application discloses an eye drop bottle with a function of preventing the bottle cap from falling off. Referring to Figure 1 and Figure 2 , the eye drop bottle with a function of preventing the bottle cap from falling off includes a medicine storage bottle 1, an inner cap 2, an outer cap 3, and a packaging layer 4. The packaging layer 4 can relatively fix the medicine storage bottle 1, the inner cap 2, and the outer cap 3, thereby ensuring that the medicine storage bottle 1, the inner cap 2, and the outer cap 3 do not rotate relative to each other during transportation or storage, and preventing the medicine storage bottle 1, the inner cap 2, and the outer cap 3 from separating from each other.

[0033] The medicine storage bottle 1 is a cylindrical bottle with one end open. An outlet nozzle 5 is integrally formed at the open end of the medicine storage bottle 1, and the outlet nozzle 5 is in communication with the inside of the medicine storage bottle 1; the outlet nozzle 5 includes a threaded section 51 and a liquid outlet section 52. The threaded section 51 and the liquid outlet section 52 are integrally formed. A first external thread is provided on the outer wall of the threaded section 51. A liquid outlet hole is provided at the end of the liquid outlet section 52 away from the medicine storage bottle 1. The liquid in the medicine storage bottle 1 can drip out through the liquid outlet hole, and the cross-sectional areas of the medicine storage bottle 1, the threaded section 51, and the liquid outlet section 52 decrease in sequence.

[0034] The shape of the inner cover 2 is adapted to the shape of the liquid outlet nozzle 5. The inner cover 2 is threadedly connected to the liquid outlet nozzle 5. The inner cover 2 includes a lower connection section 21 and an upper connection section 22. The lower connection section 21 and the upper connection section 22 are integrally formed, and the cross-sectional diameter of the upper connection section 22 is smaller than that of the lower connection section 21. A first internal thread is provided on the inner wall of the lower connection section 21, and the first internal thread is adapted to the first external thread, so that the lower connection section 21 is threadedly connected to the threaded section 51. A second external thread is provided on the outer wall of the upper connection section 22 for connecting to the outer cover 3. A plurality of ribs 211 are further provided on the outer wall of the lower connection section 21. The surface of the ribs 211 is arc-shaped. The plurality of ribs 211 are arranged along the circumferential direction of the lower connection section 21, and the ribs 211 are arranged in the vertical direction.

[0035] The outer cover 3 is a barrel-shaped structure with one end closed. The diameter of the closed end is smaller than that of the open end, and the cross-section of the outer peripheral wall of the outer cover 3 is polygonal, making it more convenient to twist the outer cover 3. A connecting cylinder 31 is integrally formed on the top of the outer cover 3. A second internal thread adapted to the second external thread is provided on the inner wall of the connecting cylinder 31. When the outer cover 3 is tightened onto the inner cover 2, the connecting cylinder 31 is threadedly connected to the upper connection section 22, thereby relatively fixing the outer cover 3 and the inner cover 2.

[0036] A plurality of clamping strips 32 are provided on the inner wall of the outer cover 3. The clamping strips 32 are arranged along the length direction of the outer cover 3. When the outer cover 3 is tightened onto the inner cover 2, the clamping strips 32 cooperate with the ribs 211. In the case of non-artificial twisting of the outer cover 3, relative rotation between the outer cover 3 and the inner cover 2 can be avoided, playing an anti-detachment role for the outer cover 3.

[0037] Reference Figure 3 and Figure 4 Furthermore, a plurality of grooves 33 are formed on the end face of the open end of the outer cover 3. The plurality of grooves 33 are evenly spaced. A ring 11 is provided on the outer wall of the medicine storage bottle 1. The ring 11 is arranged close to the liquid outlet nozzle 5, and the outer diameter of the ring 11 is larger than the outer diameter of the open end of the outer cover 3. A plurality of protrusions 111 are integrally formed on the side of the ring 11 facing the outer cover 3. The plurality of protrusions 111 are arranged along the radial direction of the ring 11, and the protrusions 111 are adapted to the grooves 33. When the outer cover 3 is tightened, the end face of the outer cover 3 abuts against the ring 11, and the protrusions 111 and the grooves 33 can increase the friction force between the outer cover 3 and the ring 11, thereby further playing an anti-detachment role for the outer cover 3.

[0038] Reference Figure 1 and Figure 2, after the medicine storage bottle 1, the inner cap 2 and the outer cap 3 are connected, the packaging layer 4 is wrapped around the outer walls of the medicine storage bottle 1 and the outer cap 3. The packaging layer 4 is made of degradable plastic. The packaging layer 4 fixes the medicine storage bottle 1 and the outer cap 3 relative to each other, further preventing the relative rotation of the medicine storage bottle 1 and the outer cap 3, thereby preventing the inner cap 2 and the outer cap 3 from falling off. A viscous substance can also be applied to the inner wall of the packaging layer 4, which can further improve the effect of the packaging layer 4 in fixing the outer cap 3 and the medicine storage bottle 1 relative to each other. An indicating arrow 41 is also marked on the outer wall of the packaging layer 4. The direction indicated by the indicating arrow 41 is the direction in which the outer cap 3 is screwed open. The indicating arrow 41 can clearly indicate the opening direction of the outer cap 3 to the user.

[0039] Reference Figure 2 and Figure 3 , an opening dotted line 42 is provided on the packaging layer 4. The opening dotted line 42 is arranged along the circumferential direction of the packaging layer 4. The opening dotted line 42 is a dotted line formed by evenly opening a plurality of small holes in the packaging layer 4. By providing the opening dotted line 42, when in use, it is easier to tear the packaging layer 4 to open the medicine bottle.

[0040] Further, the opening dotted line 42 is arranged at the port position of the outer cap 3, and due to the arrangement of the ring 11, the ring 11 can abut against the position of the opening dotted line 42, so that by pressing the packaging layer 4, the opening dotted line 42 is more likely to crack, and the packaging layer 4 is more easily torn.

[0041] An easy-to-tear strip 421 is also provided on the opening dotted line 42. The easy-to-tear strip 421 is connected to the opening dotted line 42. When tearing the packaging layer 4, the packaging layer 4 can also be torn by pulling the easy-to-tear strip 421 by hand.

[0042] The implementation principle of an eye medicine bottle with a function of preventing the cap from falling off according to an embodiment of the present application is: by wrapping the packaging layer 4 around the outer walls of the outer cap 3 and the medicine storage bottle 1, the packaging layer 4 fixes the outer cap 3 and the medicine storage bottle 1 relative to each other. During transportation and storage, the relative rotation of the outer cap 3 and the medicine storage bottle 1 is avoided, effectively preventing the outer cap 3 or the inner cap 2 from falling off the medicine storage bottle 1.

[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
