Description

Technical Field

[0001] This application relates to the technical field of liquid storage bottles, and in particular to an anti-theft liquid storage bottle. Background Technology

[0002] Liquid storage bottles are extremely common containers in many fields, including industrial production and daily life, and are widely used for storing various liquids. With the continuous development of various industries, the demand for liquid storage bottles is becoming increasingly diversified and specialized. In industries such as food, chemicals, and pharmaceuticals, liquid storage bottles play a crucial role in ensuring the quality and safety of liquids, directly affecting product quality and final performance. At the same time, they also facilitate the transportation and storage of liquids, greatly improving the efficiency of liquid management.

[0003] In traditional liquid storage bottle designs, the container for storing liquids is mostly a simple, straight-sided bottle with a cap. When the liquid in these bottles needs to be used, people usually pour it out by tilting the bottle. This method is relatively simple and direct in some common applications and can meet basic usage needs. Moreover, this straight-sided bottle with a cap design is relatively simple to manufacture, has low cost, and is conducive to large-scale production and widespread adoption.

[0004] However, existing liquid storage bottles have significant shortcomings. On the one hand, in certain situations, pouring liquids can lead to unnecessary waste and inconvenience for users. On the other hand, when these bottles are used to store high-value liquids, the lack of effective anti-theft measures makes them vulnerable to theft. Utility Model Content

[0005] In order to reduce the possibility of accidental separation between the bottle body and the cap of the liquid storage bottle and improve the anti-theft performance of the liquid storage bottle, this application provides an anti-theft liquid storage bottle.

[0006] The anti-theft liquid storage bottle provided in this application adopts the following technical solution:

[0007] An anti-theft liquid storage bottle includes a bottle body and a cap assembly. The cap assembly includes an inner cap and an anti-theft ring. The upper end of the bottle body has a liquid storage cavity for storing liquid. The inner cap is threaded to the bottle body to cover the opening of the liquid storage cavity. A limiting ring is connected to the outer periphery of the bottle body near the inner cap. The limiting ring has a plurality of ratchet grooves on its outer periphery, which are circumferentially spaced around the axis of the bottle body. The anti-theft ring is connected to the limiting ring. An insert is connected to the inner wall of the anti-theft ring. One end of the insert along the axis of the bottle body is fixedly connected to one end of the inner cap. One end of the insert abuts against the wall of the ratchet groove to prevent the inner cap from separating from the bottle body.

[0008] By adopting the above technical solution, the inner wall of the anti-theft ring is connected to an insert, which is fixedly connected to the inner cover. The insert is embedded in the ratchet groove, which prevents the inner cover from rotating in the direction of separation from the bottle body, reducing the possibility of accidental separation between the inner cover and the bottle body. When it is necessary to open the inner cover, more force is required to break the connection between the inner cover and the insert, thereby improving the anti-theft performance of the liquid storage bottle.

[0009] Preferably, there are several inserts, and the inserts are distributed circumferentially around the axis of the anti-theft ring.

[0010] By adopting the above technical solution, several inserts are provided to improve the connection strength between the anti-theft ring and the inner cover, reduce the possibility of accidental breakage at the connection between the insert and the inner cover, and the multiple inserts are distributed and embedded in multiple ratchet grooves to improve the anti-theft performance of the liquid storage bottle.

[0011] Preferably, the bottle cap assembly further includes an outer cap, one end of which is provided with an outer receiving groove. The inner cap is embedded in the outer receiving groove. A retaining ring is connected to the outer periphery of the inner cap near the anti-theft ring. A retaining ring is connected to the groove wall of the outer receiving groove. The retaining ring is used to abut against the surface of the retaining ring near the bottom of the outer receiving groove. The outer periphery of the retaining ring is provided with a third chamfer. The third chamfer is located on the side of the retaining ring away from the anti-theft ring. The third chamfer is used to abut against the end of the inner wall of the retaining ring away from the bottom of the outer receiving groove.

[0012] By adopting the above technical solution, an outer cover is set and the inner cover is embedded in the outer receiving groove, which avoids external objects from directly contacting the inner cover. When it is necessary to rotate the inner cover, the outer cover and the inner cover need to be circumferentially fixed or the outer cover needs to be removed. A retaining ring and a retaining ring are set to reduce the possibility of accidental separation of the outer cover and the inner cover and improve the reliability of the liquid storage bottle.

[0013] Preferably, the outer receiving groove wall is connected with a plurality of reinforcing ribs, and the plurality of reinforcing ribs are distributed circumferentially around the axis of the outer cover.

[0014] By adopting the above technical solution, reinforcing ribs are connected to the outer receiving tank wall to improve the structural strength of the outer cover.

[0015] Preferably, the reinforcing rib has an abutment groove at the end away from the bottom of the outer receiving groove, the bottom of the abutment groove abuts the end of the inner cover away from the anti-theft ring, and the end of the inner cover near the bottom of the outer receiving groove is connected to a protrusion. The end of the protrusion near the bottom of the outer receiving groove has a second chamfer, and the second chamfer is located on one side of the protrusion along the circumferential direction of the inner cover axis.

[0016] By adopting the above technical solution, when the outer cover is rotated at will, the reinforcing rib abuts against the second chamfer, causing the outer cover to slide away from the anti-theft ring along the outer cover axis. When it is necessary to separate the inner cover from the bottle body, the bottom of the abutting groove is pressed against the inner cover, and the outer cover is rotated so that the outer cover abuts against the protrusion, thereby driving the inner cover to rotate.

[0017] Preferably, the outer cover has a plurality of anti-slip grooves on its outer periphery, and the plurality of anti-slip grooves are distributed circumferentially around the axis of the outer cover.

[0018] By adopting the above technical solution, several anti-slip grooves are provided on the outer wall of the outer cover to increase the friction between the user's fingers and the outer cover, making it easier to drive the outer cover to rotate.

[0019] Preferably, it also includes a bottle stopper, one end of which is embedded in the liquid storage cavity, the outer wall of which abuts against the wall of the liquid storage cavity, and the other end of which is connected to a bottle mouth. The end of the bottle mouth away from the bottle stopper is provided with a liquid outlet channel, which passes through the bottle mouth and the bottle stopper.

[0020] By adopting the above technical solution, a bottle stopper is provided, and the other end of the bottle stopper is provided with a bottle nozzle, which makes it easy to accurately drip the liquid in the storage chamber to the designated area, thereby improving the convenience of the storage bottle.

[0021] Preferably, the outer periphery of the stopper away from the bottle mouth is provided with a first chamfer, which is used to abut against the wall of the liquid storage cavity.

[0022] By adopting the above technical solution, one end of the bottle stopper is provided with a first chamfer, which guides the assembly of the bottle stopper and facilitates the insertion of the bottle stopper into the liquid storage cavity.

[0023] Preferably, the outer periphery of the stopper near the bottle mouth is connected to an abutment ring, and the surface of the abutment ring away from the bottle mouth is used to abut against the end of the bottle body near the inner cap.

[0024] By adopting the above technical solution, an abutment ring is provided on the outer periphery of the bottle stopper. The abutment ring abuts against the bottle body and limits the position of the bottle stopper, preventing the bottle stopper from being completely embedded in the liquid storage cavity. This reduces the possibility of liquid in the liquid storage cavity spinning away from the connection between the bottle body and the bottle stopper, and improves the sealing performance between the bottle stopper and the bottle body.

[0025] Preferably, the inner cap is connected to a plug at one end near the bottle mouth, the plug is embedded in the liquid outlet channel, and the outer wall of the plug abuts against the inner wall of the liquid outlet channel.

[0026] By adopting the above technical solution, the blockage area is sealed against the inner wall of the liquid outlet channel, preventing outside air from entering the liquid storage chamber and thus reducing the possibility of contamination of the liquid inside the storage chamber, thereby improving the reliability of the liquid storage bottle.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. The inner wall of the anti-theft ring is connected to an insert, which is fixedly connected to the inner cover. The insert is embedded in the ratchet groove, which prevents the inner cover from rotating in the direction of separation from the bottle body, reducing the possibility of accidental separation between the inner cover and the bottle body. When it is necessary to open the inner cover, more force is required to break the connection between the inner cover and the insert, thus improving the anti-theft performance of the liquid storage bottle.

[0029] 2. Several inserts are provided to improve the connection strength between the anti-theft ring and the inner cover, reduce the possibility of accidental breakage at the connection between the insert and the inner cover, and multiple inserts are distributed and embedded in multiple ratchet grooves to improve the anti-theft performance of the liquid storage bottle;

[0030] 3. An outer cover is provided, and the inner cover is embedded in the outer receiving groove to prevent external objects from directly contacting the inner cover. When the inner cover needs to be rotated, the outer cover and the inner cover need to be circumferentially fixed or the outer cover needs to be removed. A retaining ring and a retaining ring are provided to reduce the possibility of accidental separation of the outer cover and the inner cover and improve the reliability of the liquid storage bottle.

[0044] Reference Figure 1 and Figure 3The device has several inserts 321, which are circumferentially spaced around the axis of the anti-theft ring 32. In this embodiment, there are four inserts 321, which are evenly distributed around the axis of the anti-theft ring 32. A ratchet groove 1321 is provided on the outer wall of the limiting ring 132. The end of the insert 321 away from the inner wall of the anti-theft ring 32 abuts against the groove wall of the ratchet groove 1321 to prevent the inner cap 31 from separating from the bottle body 1. There are several ratchet grooves 1321, which are divided into two groups. The two groups of ratchet grooves 1321 are circumferentially spaced around the axis of the limiting ring 132, and several ratchet grooves 1321 in the same group are circumferentially spaced around the axis of the limiting ring 132. In this embodiment, there are eight ratchet grooves 1321, with four ratchet grooves 1321 in the same group evenly distributed around the axis of the limiting ring 132.

[0045] Reference Figure 1 and Figure 4 The bottle cap assembly 3 also includes an outer cap 33. One end of the outer cap 33 is coaxially provided with an outer receiving groove 331. The inner cap 31 is embedded in the outer receiving groove 331. The outer wall of the outer cap 33 near the limiting ring 132 is flush with the outer wall of the anti-theft ring 32. Several reinforcing ribs 332 are fixedly connected to the groove wall of the outer receiving groove 331. The length direction of the reinforcing ribs 332 is parallel to the axial direction of the outer cap 33, and the reinforcing ribs 332 are circumferentially spaced around the axial direction of the outer cap 33. In this embodiment, there are six reinforcing ribs 332, which are evenly distributed circumferentially around the axial direction of the outer cap 33. The end of the reinforcing rib 332 near the anti-theft ring 32 is provided with an abutment groove 3321. The side of the abutment groove 3321 away from the groove wall of the outer receiving groove 331 passes through the reinforcing rib 332, and the end of the inner cap 31 away from the anti-theft ring 32 abuts against the bottom of the abutment groove 3321. The abutment groove 3321 has a sixth chamfer 3322 at the end of the groove wall away from the bottom of the outer receiving groove 331. The sixth chamfer 3322 is used to abut against the end of the inner cover 31 near the protrusion 313.

[0046] Reference Figure 5 A plurality of protrusions 316 are fixedly connected to one end of the inner cover 31 near the protrusion 313, and the protrusions 316 are distributed circumferentially around the axis of the inner cover 31. In this embodiment, there are six protrusions 316, which are evenly distributed circumferentially around the axis of the inner cover 31, with one protrusion 316 between two adjacent reinforcing ribs 332. The end of the protrusion 316 away from the inner cover 31 is provided with a second chamfer 3161, which is located on one side of the protrusion 316 along the circumferential direction of the axis of the inner cover 31. In this embodiment, when the outer cover 33 rotates in the direction of the inner cover 31 away from the bottle body 1, the reinforcing rib 332 abuts against the second chamfer 3161.

[0047] Reference Figure 4A retaining ring 317 is coaxially fixed to the outer periphery of the inner cover 31 near the anti-theft ring 32. The retaining ring 317 has a third chamfer 3171 on its outer periphery, located on the side of the retaining ring 317 away from the anti-theft ring 32. A retaining ring 333 is coaxially fixed to the wall of the outer receiving groove 331. The surface of the retaining ring 333 near the anti-theft ring 32 is flush with the end of the outer cover 33 near the anti-theft ring 32. The inner wall of the retaining ring 333 has a fourth chamfer 3331 and a fifth chamfer 3332. The fourth chamfer 3331 is embedded in the side of the retaining ring 333 near the anti-theft ring 32 and is used to abut against the third chamfer 3171. The fifth chamfer 3332 is located on the side of the retaining ring 333 away from the anti-theft ring 32 and is used to abut against the outer wall of the retaining ring 317 near the anti-theft ring 32. In this embodiment, the included angle between the fifth chamfer 3332 and the wall of the outer receiving groove 331 is greater than the included angle between the fourth chamfer 3331 and the wall of the outer receiving groove 331.

[0048] Reference Figure 1 The outer wall of the outer cover 33 is provided with a plurality of anti-slip grooves 334, which are distributed circumferentially around the axis of the outer cover 33. In this embodiment, there are four groups of anti-slip grooves 334, which are evenly distributed circumferentially around the axis of the outer cover 33, and a plurality of anti-slip grooves 334 in the same group are evenly distributed circumferentially around the axis of the outer cover 33.

[0049] The implementation principle of an anti-theft liquid storage bottle according to an embodiment of this application is as follows: When the outer cover 33 is accidentally rotated, if it is rotated in the direction of separation between the inner cover 31 and the bottle body 1, the reinforcing rib 332 abuts against the second chamfer 3161, so that the outer cover 33 slides away from the bottle body 1. If it is rotated in the direction of tightening the inner cover 31 and the bottle body 1, the reinforcing rib 332 abuts against the protrusion 316, so that the inner cover 31 and the bottle body 1 are tightened.

[0050] When it is necessary to separate the inner cap 31 and the bottle body 1, press the outer cap 33 so that the bottom of the abutment groove 3321 presses against the end of the inner cap 31 near the protrusion 313. Rotate the outer cap 33, the reinforcing rib 332 abuts against the second chamfer 3161, and drives the inner cap 31 to rotate. The insert 321 presses against the wall of the ratchet groove 1321, so that the connection between the insert 321 and the inner cap 31 is broken, thus realizing the separation of the inner cap 31 and the bottle body 1.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
