Abstract
Description
Technical Field
[0001] This utility model relates to the field of bottle cap technology, and more specifically, to a simple bottle cap and container bottle. Background Technology
[0002] Taking bottle caps for alcoholic beverages as an example, these caps typically consist of plastic parts such as an outer cap, outer sleeve, inner cap, liner, inner stopper, and inner sleeve. However, in some mid-to-low-end alcoholic beverage products, some plastic parts are omitted to reduce costs. For instance, patent document CN205707973U discloses a simple multi-piece combination bottle cap consisting only of an upper cap, lower cap, liner, inner stopper, and bottle neck stopper. However, this prior art still has some drawbacks. For example, after opening the bottle cap, it is necessary to pull the ring on the top of the bottle neck stopper to remove it. This not only makes the structure of the bottle neck stopper more complex, but also makes it difficult to directly pull out the bottle neck stopper, as it is fixed by an interference fit, which may affect the consumer experience. Utility Model Content
[0003] The purpose of this invention is to provide a simple bottle cap and container to overcome the aforementioned deficiencies of the prior art.
[0004] This utility model is achieved through the following technical solution:
[0005] A simple bottle cap includes an outer cap, an outer sleeve, an inner plug, and a sealing plug. The inner wall of the outer sleeve has a connecting structure for connecting to the bottle mouth. The outer cap and the outer sleeve are connected by threads. The inner plug is used to fit with the bottle mouth and act as a bottle nozzle. The sealing plug is fixedly connected to the inside of the outer cap and seals the inner plug.
[0006] Optionally, the sealing plug includes an annular plate and a plug cylinder disposed at the bottom of the annular plate. The plug cylinder is interference-fitted with the inner plug. The inner wall of the outer cover is provided with a plurality of support brackets spaced apart along the circumferential direction. The annular plate is pressed between the support brackets and the inner top of the outer cover.
[0007] Optionally, the inner plug has a flange that can cover the bottle mouth, and a limiting structure for restricting the upward displacement of the inner plug is provided between the outer wall of the flange and the inner wall of the outer sleeve.
[0008] Optionally, the limiting structure includes mutually cooperating limiting brackets and limiting annular grooves, with the limiting brackets spaced apart along the circumferential direction on the inner wall of the outer jacket, and the limiting annular grooves located on the outer wall of the flange.
[0009] Optionally, the outer wall of the outer jacket is provided with a limiting step in the middle that abuts against the outer cover, and the upper outer wall of the outer jacket is connected to the inner wall of the outer cover by threads.
[0010] Optionally, the top of the limiting step is provided with anti-counterfeiting teeth, and the lower end of the outer cover is provided with a notch for accommodating the anti-counterfeiting teeth so that the anti-counterfeiting teeth can be broken off when the outer cover is unscrewed; the upper threaded surface on the outer wall of the outer sleeve and / or the lower threaded surface on the inner wall of the outer cover have guide slopes so that the outer cover can be connected to the outer sleeve by press fitting.
[0011] Optionally, the inner edge of the top of the inner plug is pointed.
[0012] This utility model also provides a container bottle, including a bottle body and a simple bottle cap as described in any of the above.
[0013] The technical solution of this utility model has at least the following advantages and beneficial effects:
[0014] 1. In this utility model, the sealing plug and the outer cover form an integral whole. When the outer cover is opened, the sealing plug separates from the inner plug along with the outer cover, eliminating the need to remove the sealing plug by pulling it out, reducing the difficulty of operation and making it more convenient for consumers to use.
[0015] 2. In this utility model, the limiting structure set between the outer wall of the inner stopper and the inner wall of the outer sleeve can restrict the upward displacement of the inner stopper. This setting can prevent the inner stopper from being taken away by the outer cap when the outer cap is opened or from falling into the wine glass when pouring wine.
[0016] 3. In this utility model, the upper surface of the thread on the outer wall of the outer sleeve and / or the lower surface of the thread on the inner wall of the outer cover have guide slopes, so that the outer cover and the outer sleeve can be assembled by press-fitting without damaging the anti-counterfeiting teeth. After assembly, the outer cover can only be opened by rotating it. When rotating the outer cover, the anti-counterfeiting teeth will be broken, thus achieving the purpose of anti-counterfeiting.

Detailed Implementation
[0025] Example 1
[0026] refer to Figure 1 A simple bottle cap includes an outer cap 1, an outer sleeve 2, an inner plug 3, and a sealing plug 4. The inner wall of the outer sleeve 2 is provided with a connecting structure for connecting to the bottle mouth. In this embodiment, the connecting structure is not specifically limited. For example, a claw provided on the inner wall of the outer sleeve 2 and extending inward can be engaged with the annular groove at the bottle neck to limit the relative axial displacement between the outer sleeve 2 and the bottle body 6. At the same time, the anti-rotation ribs provided on the inner wall of the outer sleeve 2 cooperate with the anti-rotation ribs at the bottle neck to limit the relative circumferential rotation between the outer sleeve 2 and the bottle body 6.
[0027] The outer cap 1 and the outer sleeve 2 are connected by threads. The inner plug 3 fits with the bottle mouth and acts as the bottle spout. It is easy to understand that the inner plug 3 is embedded in the bottle mouth and forms a sealing pair with the inner wall of the bottle mouth (usually the inner plug 3 and the bottle mouth are interference-fitted). The inner plug 3 extends upwards to act as the bottle spout, meaning that when pouring wine, the liquid is poured out from the top edge of the inner plug 3. Alternatively, in this embodiment, the top inner edge of the inner plug 3 is pointed. This design can, to some extent, prevent the liquid from flowing onto the outer wall of the bottle body 6 after each pour.
[0028] In this embodiment, the sealing plug 4 is fixedly connected to the inside of the outer cover 1 and seals the inner plug 3. That is, the sealing plug 4 and the outer cover 1 form a whole. When the outer cover 1 is opened, the sealing plug 4 separates from the inner plug 3 along with the outer cover 1. There is no need to remove the sealing plug 4 by pulling it out, which reduces the difficulty of operation and makes it more convenient for consumers to use.
[0029] refer to Figures 1-4 As an alternative, in this embodiment, the sealing plug 4 is fixedly connected to the outer cover 1 in the following way: the sealing plug 4 includes an annular plate 401 and a plug cylinder 402 disposed at the bottom of the annular plate 401. The plug cylinder 402 is interference-fitted with the inner plug 3. The inner wall of the outer cover 1 is provided with a plurality of support brackets 101 spaced apart along the circumferential direction. The annular plate 401 is pressed between the support brackets 101 and the inner top of the outer cover 1. It should be understood that "fixed connection" here means restricting the separation of the sealing plug 4 and the outer cover 1, and does not necessarily mean that the two are fixed relative to each other. In other embodiments, "fixed connection" can of course also mean that the two are completely fixed. For example, in some embodiments, the sealing plug 4 and the outer cover 1 are fixed by adhesive bonding or heat pressing.
[0030] refer to Figure 1 as well as Figures 5-7In this embodiment, the inner plug 3 is provided with a flange that can cover the bottle mouth. A limiting structure is provided between the outer wall of the flange and the inner wall of the outer sleeve 2 to limit the upward displacement of the inner plug 3. This setting can prevent the inner plug 3 from being taken away by the outer sleeve 1 when the outer sleeve 1 is opened or from falling into the wine glass when pouring wine.
[0031] As an alternative, the limiting structure in this embodiment is as follows: the limiting structure includes mutually cooperating limiting platforms 202 and limiting annular grooves 301. The limiting platforms 202 are spaced apart along the circumferential direction on the inner wall of the outer sleeve 2, and the limiting annular grooves 301 are located on the outer wall of the flange. After the outer sleeve 2 and the inner plug 3 are pressed together, if the inner plug 3 moves upward, the limiting annular groove 301 will abut against the limiting platforms 202, restricting the inner plug 3 from continuing to move upward. In other embodiments, the limiting structure can of course be other structures, such as having several locking blocks on the inner wall of the outer sleeve 2 and locking holes on the outer wall of the inner plug 3 that cooperate with the locking blocks one by one.
[0032] refer to Figures 1-3 as well as Figure 5 and Figure 6 In this embodiment, the outer wall of the outer jacket 2 is provided with a limiting step 201 in the middle, which abuts against the outer cover 1, so as to facilitate the connection between the outer jacket 2 and the outer cover 1. It is easy to understand that the limiting step 201 divides the outer jacket 2 into upper and lower sections. The upper end is connected to the inner wall of the outer cover 1 by threads, while the lower section is exposed on the outside.
[0033] The top of the limiting step 201 is provided with an anti-counterfeiting tooth 203, and the lower end of the outer cover 1 is provided with a notch 102 for accommodating the anti-counterfeiting tooth 203, so that the anti-counterfeiting tooth 203 will break when the outer cover 1 is unscrewed. Based on this, in this embodiment, the upper surface of the thread on the outer wall of the outer sleeve 2 and the lower surface of the thread on the inner wall of the outer cover 1 have guide slopes 5. Due to the presence of guide slopes 5 and the elasticity of the plastic part, the outer cover 1 and the outer sleeve 2 can be assembled into place by press fitting without damaging the anti-counterfeiting tooth 203. After assembly, the outer cover 1 can only be opened by rotating it. When the outer cover 1 is rotated, the anti-counterfeiting tooth 203 will break, thus achieving the purpose of anti-counterfeiting. It is easy to understand that in other embodiments, the guide slope 5 can also be provided only on the upper surface of the thread on the outer wall of the outer sleeve 2, or only on the lower surface of the thread on the inner wall of the outer cover 1.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
