Description

Technical Field

[0001] The utility model relates to the technical field of beverage bottles, in particular to a fresh-keeping beverage bottle. Background Art

[0002] The existing beverage storage bottles generally consist of two layers inside. One layer is the outer bottle shell, and the other layer is the inner bag used to directly contact and store beverages. When some wine bottles pour out wine and fill it in, a wine spear is inserted into the outer bottle shell and then gas is filled, so that the air pressure in the outer bottle shell suddenly rises. The pressure of the air pressure acts on the inner bag, and the wine in the inner bag is pressed to the mouth of the inner bag and flows out.

[0003] However, for the existing beverage bottles, since gas needs to effectively enter and exit between the inner bag and the outer bottle shell, the inner bag and the outer bottle shell are not completely sealed. Therefore, when the user unscrews the bottle cap of the beverage bottle, the inner bag will rotate with the bottle cap.

[0004] Because the inner bag is installed inside the outer bottle shell, when the bottle cap is tightened, the inner bag and the top opening of the outer bottle shell are naturally tightened. However, one point is overlooked. Before the inner bag is installed into the outer bottle shell, the inner bag is empty and the opening of the inner bag is open. Therefore, at this time, the inner bag is likely to enter dust with air, and the beverage filled in the inner bag is easily contaminated and deteriorated. Content of the Utility Model

[0005] The purpose of the utility model is to provide a fresh-keeping beverage bottle to overcome the deficiencies in the prior art.

Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0023] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. When the number of an element is referred to as having "a plurality", it can be any number of two or more. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation manner.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0025] The following will describe the present utility model in detail with reference to the embodiments shown in the accompanying drawings:

[0026] As Figures 1 - 3 shown, in this embodiment, a fresh - keeping beverage bottle is provided, which includes an outer bottle shell 3. An inner bag 2 is installed inside the outer bottle shell 3. A bottle stopper 8 is fixedly arranged at the top of the inner bag 2. The upper opening of the bottle stopper 8 is provided with a sealing surface with a tearing strip 4 to ensure that the inside of the inner bag 2 is clean before the liquid is filled. The bottle stopper 8 and the outer bottle shell 3 are respectively provided with corresponding anti - rotation structures, and the anti - rotation structures are used to prevent the bottle stopper 8 from rotating relative to the outer bottle shell 3. When the inner bag 2 with the sealing surface having the tearing strip 4 is not used to hold the beverage, the tearing strip 4 can seal the opening of the inner bag 2, ensuring the sealing performance and cleanliness inside the inner bag 2, effectively avoiding the deterioration of the beverage and extending the storage period. Further elaborating, a constant - volume accommodation chamber is arranged inside the outer bottle shell 3, and the inner bag 2 is located inside the accommodation chamber. This accommodation chamber after putting the inner bag 2 is equivalent to a pre - set air - pressure cavity between the outer bottle shell 3 and the inner bag 2, and the air - pressure cavity is communicated with the outside through a communication groove 7, an air - ventilation gap 6 and an air - ventilation groove 5.

[0027] Before filling the beverage, the sealing surface is closed. When filling the beverage, the filling valve will break the sealing surface with the tear strip 4, and the sealing surface is in an open state to fill the beverage. As the beverage continues to enter, the volume inside the outer bottle shell 3 is constant, so the gas inside the outer bottle shell 3 (the air retained between the outer bottle shell 3 and the inner bag 2) will be squeezed out.

[0028] When pouring a beverage, it is just pouring a beverage in a normal way, unscrewing the bottle cap and pouring out the beverage. In order to achieve air pressure balance with the outside, the outside gas will sequentially pass through the venting groove 5, the venting gap 6 and the connecting groove 7 into the preset air pressure cavity between the inner bag 2 and the outer bottle shell 3.

[0029] In this embodiment, the anti-rotation structure includes a limiting protrusion and a groove. The limiting protrusion is arranged on the outer peripheral side of the bottle plug 8. A support is arranged at the bottle mouth of the outer bottle shell 3. The support is formed by the inner side wall of the outer bottle shell 3 extending inward in a circular shape. The groove is arranged on the support, and the limiting protrusion is used to engage with the groove. After the bottle cap rotates, the limiting protrusion will be supported by the groove, so even if the bottle plug 8 is driven by the bottle cap, the bottle plug 8 will not rotate.

[0030] The limiting protrusion is inserted into the groove, and then the bottle stopper 8 is placed on the above-mentioned support platform for limiting assembly. Further, the groove is formed by the surface of the support platform being recessed and extended downward in the axial direction. Further, the bottle stopper 8 is composed of two cylinders with different diameters, and the diameter of the cylinder near the upper part of the bottle stopper 8 is larger than the diameter of the cylinder at the lower part of the bottle stopper 8, so that the bottle stopper 8 can be placed on the support platform.

[0031] In this embodiment, a ventilation groove 5 is provided in the middle of the limiting protrusion, and a ventilation gap 6 is also provided on the side wall of the limiting protrusion. The bottle stopper 8 includes a plurality of abutment rings fixedly arranged on the outer peripheral side, and the plurality of abutment rings are used to abut against the inner wall of the support. Therefore, after the abutment ring abuts against the inner wall of the support, the connecting groove 7 provided on the abutment ring will form a channel with the support to allow gas to pass. It is worth mentioning that, in order to further improve the efficiency of ventilation, it is preferred to provide some ventilation holes extending to the top of the bottle stopper 8 at the top of the bottle stopper 8 to exchange gas with the outside world. Optionally, the ventilation holes can be connected to the ventilation groove 5.

[0032] In other embodiments, the positions of the limiting protrusion and the groove can also be swapped. The anti-rotation structure includes a limiting protrusion and a groove. A support is provided at the bottle mouth of the outer bottle shell, and the limiting protrusion is formed by the surface of the support protruding upward in the axial direction; the limiting protrusion is arranged in a ring on the inner side wall of the support, and the support is formed by the inner side wall of the outer bottle shell extending inward in a ring shape. The groove is arranged on the bottle stopper, and the limiting protrusion is used to engage with the groove.

[0033] The groove is formed by axially extending downward from the surface of the bottle stopper. Since the bottle stopper consists of two cylinders with different diameters, the diameter of the upper cylinder of the bottle stopper is larger than that of the lower cylinder, so that the bottle stopper can be placed on the support platform. Therefore, the groove is provided on the upper cylinder, extending upward axially from the bottom of the cylinder so as to be engaged with the limit lug. It is worth mentioning that the positions, quantities, and respective angles in the annular distribution of the grooves and limit lugs appearing in the above text all correspond to each other.

[0034] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification. For those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
