Description

bottle cap

technical field

The utility model relates to a bottle body cover, in particular to a sealing (unopened) state which is easy to identify and which can still maintain an excellent sealing effect after unsealing, so that the sealed objects in the bottle have excellent preservation Environmental bottle closures.

Background technique

The common bottle body capping structure is generally common in plastic or PE bottles with external threads on the periphery of the bottle mouth, and a metal cap with internal threads is directly screwed on the external threads of the bottle mouth (that is, generally Common plastic bottle caps), using plastic or PE materials with a certain degree of elastic deformation, can achieve a good airtight effect, and because of its simple structure and low cost, it has been widely used in low-priced liquid beverage products Packaging; however, the above-mentioned bottle capping structure can achieve better airtight effect only when it is applied to soft and elastically deformable bottle materials (such as: plastic or PE). Bottles or containers made of materials that cannot be deformed (such as glass, metal, etc. with high-quality textures) cannot produce the preset sealing function, so there is a limitation in its scope of application.

In addition, a metal cover is directly pressed on the bottle mouth of a hard and difficult-to-deform bottle such as glass or a container, and the wrinkles produced on the periphery of the metal cover are used to clamp and cover the bottle mouth, which is a common beer bottle cap. It also has an excellent airtight (sealing) effect; however, this structure requires a specific opening tool, that is, a bottle opener, when it is opened, and the metal bottle cap is deformed after opening and cannot maintain airtightness. It is suitable for Bottles and containers for single use or very short storage time.

Another example is the bottle of champagne, which is filled with a conformable cork in the mouth of the glass bottle, which can also achieve a certain degree of excellent sealing and preservation effect; but the same, it also requires a specific opening tool to open it. That is, the cork bottle opener, and after opening, not only the cork is not easy to plug back into the bottle mouth, but also the cork is easy to break, which reduces the preservation function of the beverage, which is also the shortcoming of the cork bottle cap application.

Utility model content

The purpose of this utility model is to overcome the shortcomings of the above-mentioned bottle body seal, and provide a kind of easy to identify the sealed (unopened) state, and can still maintain an excellent sealing effect after unsealing, so that the seal in the bottle The bottle cap with excellent preservation environment.

The utility model tightly clamps a bottle mouth cover on the bottle mouth of a preset bottle body or container. An outer threaded outer sleeve is arranged on the top of the bottle mouth sleeve, and a hollow conical convex with the same center is arranged inside the outer sleeve. There are a plurality of hollow flow holes on the periphery of the conical convex part, and a rotating cap with internal thread can be screwed on the outer periphery of the bottle mouth sleeve. A flow channel is arranged in the center of the rotating cap, and the flow A conical mouth matching the conical convex part is set under the channel, and a plurality of axially extending convex ribs are provided on the outer peripheral edge of the rotating cap, which can be inserted into a preset guide groove on the inner peripheral edge of a hat-shaped inner sleeve to form a Sliding, there is a through hole in the center of the top surface of the inner sleeve corresponding to the flow channel of the rotating cap, and the inner edge of the bottom opening of the inner sleeve is provided with a stop flange, which can be clamped to the preset outer ring on the outer periphery of the bottle mouth sleeve The flange forms an inseparable hooking state. When in use, turn the inner sleeve to link the rotary cap, and use the rotary cap and the inner sleeve to generate relative displacement through the thread, so that the rotary cap can be changed to fit with a tapered mouth The state of blocking the flow hole by the tapered convex part of the bottle mouth sleeve, thereby achieving a bottle body cap that is easy to open repeatedly and can ensure a sealed state.

In addition, the utility model can fit an outer cover outside the inner sleeve, and an easily broken punching line is arranged in the center of the top surface of the outer cover corresponding to the through hole of the inner sleeve. During the opening action, the flow channel can protrude outward from the through hole of the inner sleeve and press against the punching line of the outer cover to break it. The unsealed state is expressed by the irreversible punching line.

Detailed ways

Please refer to Fig. 1 and shown in Fig. 2, the utility model includes parts such as bottle mouth cover 1, rotating cap 2, inner cover 3 and outer cover 4, wherein this bottle mouth cover 1 is a tubular shape, and the outer periphery of middle section is provided with a The outer ring flange 15 is provided with an outer casing 11 with an external thread 111 at one end, and a hollow conical convex part 12 is provided in the outer casing 11, and a plurality of hollow flow holes 121 are arranged on the periphery of the conical convex part 12 , an annular accommodation chamber 13 is provided on the inner edge of the middle section of the bottle mouth cover 1, and an inner ring flange 14 is provided on the side of the annular accommodation chamber 13, so that the annular accommodation chamber 13 is sleeved on the bottle Bottle mouth 51 outside outer ring flange 52 of body 5, cooperate this inner ring flange 14 to stop at outer ring flange 52 lower edges, can make bottleneck cover 1 stably be positioned on the bottleneck 51 of bottle body 5, again A leak-proof gasket 53 is placed between the bottle mouth 51 and the bottle mouth cover 1, so that an airtight connection can be maintained between the bottle mouth cover 1 and the bottle body 5, and the inner ring flange 14 is connected to the other end. There are a plurality of ribs 141 extending in parallel, which can be bound to the outer peripheral edge of the bottle mouth 51 of the bottle body 5, so as to avoid the mutual rotation between the bottle mouth cover 1 and the bottle body 5. The inner peripheral edge of the rotating cap 2 is provided with an internal thread 22 for Screwed on the external thread 111 of the bottle mouth cover 1, a through flow channel 23 is provided in the center of the rotary cap 2, and the flow channel 23 extends a gradually expanding tapered mouth 231 in the rotary cap 2, and the rotary cap 2 The outer peripheral edge of the inner sleeve 3 is provided with a plurality of axially extending ribs 21, and the inner sleeve 3 is in the shape of a cap, and its inner peripheral edge is provided with a plurality of axially extending guide grooves 33, which can be inserted by the ribs 21 of the aforementioned rotating cap 2. Sliding, and the center of the top surface of the inner sleeve 3 is provided with a through hole 31 corresponding to the flow channel 23 of the aforementioned rotary cap 2, and the inner edge of the bottom opening of the inner sleeve 3 is provided with a plurality of stop flanges 32, which can be hooked to the bottle mouth The outer ring flange 15 of the cover 1 forms an inseparable hooked state, the outer cover 4 is bonded to the outer peripheral edge of the inner cover 3, and an easy-to-break punching line 41 is provided in the center of the top surface corresponding to the inner cover 3.
