Description

Technical Field

[0001] The present invention relates to the field of nonferrous metal processing, and in particular to a bottle cap assembly having a titanium sleeve and a cap body. Background Art

[0002] Bottle caps are widely used to cover beverages, including soda, liquor, red wine, beer, fruit and vegetable juice, etc. Beverages on the market usually have different specifications, with liquor and red wine as typical representatives. Beverages of common specifications are often difficult for consumers to consume at one time. At this time, bottle caps are needed to seal the beverage container to prevent the beverage from spilling from the container.

[0003] Taking red wine as an example, most of the red wine containers on the market are glass bottles, and their bottle caps are matching corks or rubber stoppers. In order to ensure the quality and taste of the red wine before opening the bottle, the red wine bottle cap is usually pressed into the bottle mouth of the glass bottle. Once the bottle cap is opened, its volume expands and it is difficult to put the bottle cap back into the bottle mouth, so it is difficult to preserve the flavor of the red wine after opening the bottle.

[0004] Similarly, most liquor containers on the market are glass bottles, and their bottle caps are usually made of metal or plastic. For anti-counterfeiting purposes, some high-end liquors have destructive structures inside the bottle caps, which makes it difficult to seal the bottle caps back on the container once they are removed. Even if they are sealed on the container, it is difficult to meet the sealing standards at the factory, affecting the taste and flavor of the liquor when it is consumed again. Summary of the invention

[0005] In view of this, the embodiment of the present disclosure provides a bottle cap assembly with a titanium sleeve and a cap body, which is arranged at the mouth of the beverage container and can be opened or closed as needed, so as to flexibly control the outflow or sealing of the beverage, so as to increase the shelf life of the beverage, maintain the flavor and taste of the beverage, and improve the drinking experience and health of beverage consumers.

[0006] In one aspect of the present disclosure, there is provided a bottle cap assembly having a titanium sleeve and a cap body, comprising:

[0007] The first plug body is made of elastic material, has a through hole between the upper and lower surfaces, and is configured to be embedded in the bottle mouth of the beverage container through its own compression;

[0008] A sleeve, which is inserted into the through hole along the length direction;

[0009] a cap body, which is elastic, is disposed inside the sleeve with its opening upward, and has a set gap with the sleeve in the radial direction of the through hole; and

[0010] The second plug body is made of elastic material and can be inserted into the opening of the cap body, so that the cap body is forced to expand outward in the radial direction of the through hole to eliminate the set gap.

[0011] In some embodiments, in the axial direction of the through hole, the position of the cap body relative to the sleeve is fixed.

[0012] In some embodiments, the cap body is fixed inside the sleeve by spot welding, and the number of welding points between the cap body and the sleeve is not less than two.

[0013] In some embodiments, the set gap is between 0.1 and 1 mm.

[0014] In some embodiments, the set gap is 0.5 mm.

[0015] In some embodiments, the first plug body comprises:

[0016] A first flange, disposed on an upper surface of the first plug body and configured to extend outwardly in a radial direction of the through hole;

[0017] an annular groove, provided on one side of the outer peripheral surface of the first plug body close to the lower surface; and

[0018] A vent hole is formed through the outer peripheral surface of the first plug body and is connected to the through hole.

[0019] In some embodiments, the sleeve comprises:

[0020] a first curling edge, disposed on an upper surface of the sleeve and configured to extend outwardly in a radial direction of the through hole; and

[0021] The second curling edge is arranged on the lower surface of the sleeve and is configured to extend outwardly along the radial direction of the through hole and fit and cover the lower surface of the first plug body.

[0022] In some embodiments, the cap body comprises:

[0023] The bell mouth is arranged at the opening of the cap body so that the opening area of ​​the cap body increases gradually from bottom to top.

[0024] In some embodiments, the sleeve and / or the cap body is made of a metal material, and the metal material includes pure titanium or a titanium alloy.

[0025] In some embodiments, the first plug body and the second plug body are made of wood material, rubber material or PET material.

[0026] Therefore, according to the embodiment of the present disclosure, by embedding the first plug in the container mouth of the beverage and controlling the second plug to be inserted into or taken out of the cap body, the container mouth of the beverage can be selectively opened or closed, thereby flexibly controlling the outflow or sealing of the beverage to increase the shelf life of the beverage; by selecting a sleeve and a cap body made of titanium or titanium alloy materials, the first plug or the second plug can be prevented from contacting the beverage, so as to maintain the flavor and taste of the beverage flowing out from between the sleeve and the cap body, thereby improving the drinking experience and health of beverage consumers.

[0037] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. The description of the exemplary embodiments is merely illustrative and is in no way intended to limit the present disclosure and its application or use. The present disclosure can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided to make the present disclosure thorough and complete and to fully express the scope of the present disclosure to those skilled in the art. It should be noted that unless otherwise specifically stated, the relative arrangement of the components and steps, the composition of the materials, the numerical expressions and the numerical values ​​set forth in these embodiments should be interpreted as being merely exemplary and not as limiting.

[0038] The words "first", "second" and similar words used in this disclosure do not indicate any order, quantity or importance, but are only used to distinguish different parts.

[0039] In the present disclosure, when a specific device is described as being located between a first device and a second device, there may or may not be an intermediate device between the specific device and the first device or the second device. When a specific device is described as being connected to other devices, the specific device may be directly connected to the other device without an intermediate device, or may not be directly connected to the other device but have an intermediate device.

[0040] All terms (including technical terms or scientific terms) used in the present disclosure have the same meanings as those understood by ordinary technicians in the field to which the present disclosure belongs, unless otherwise specifically defined. It should also be understood that terms defined in general dictionaries, such as general dictionaries, should be interpreted as having meanings consistent with their meanings in the context of the relevant technology, and should not be interpreted in an idealized or extremely formal sense, unless explicitly defined herein.

[0041] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0042] like Figures 1 to 5 As shown, for the convenience of description, the up and down directions in the figure are used as the up and down directions in the following description, and a cylindrical coordinate system is established with the through hole 11 of the first plug body 1 as the object, so as to describe the radial, circumferential and axial directions.

[0043] In one aspect of the present disclosure, there is provided a bottle cap assembly having a titanium sleeve and a cap body, comprising:

[0044] The first plug body 1 is made of elastic material, has a through hole 11 between the upper and lower surfaces, and is configured to be embedded in the bottle mouth of the beverage container through its own compression;

[0045] The sleeve 2 is inserted into the through hole 11 along the length direction;

[0046] The cap body 3 is elastic and is disposed inside the sleeve 2 with its opening facing upward, and has a set gap with the sleeve 2 in the radial direction of the through hole 11; and

[0047] The second plug body is made of elastic material and can be inserted into the opening of the cap body 3, so that the cap body 3 is forced to expand outward in the radial direction of the through hole 11 to eliminate the set gap.

[0048] The bottle cap assembly with titanium sleeve and cap provided by the present disclosure realizes a sealed connection between the bottle cap assembly with titanium sleeve and cap and the beverage container through the first plug body 1, realizes the flow of beverage from the bottle cap assembly with titanium sleeve and cap through the set gap between the sleeve 2 and the cap 3, and then realizes the gap control of the set gap through the pressure of the second plug body on the cap 3, thereby stopping the flow of beverage from the bottle cap assembly with titanium sleeve and cap, and realizes the function of selectively opening or closing the container mouth of the beverage. Therefore, before the beverage in the container is consumed, especially when the original bottle cap or disposable bottle cap loses its sealing effect, the beverage container is sealed, and when it is continued to be used, it only needs to remove the expansion pressure of the second plug body on the cap 3 to make the beverage flow out from the set gap between the sleeve 2 and the cap 3.

[0049] In some embodiments, in order to ensure the stability of the set gap, the position of the cap body 3 relative to the sleeve 2 is fixed in the axial direction of the through hole 11. In this case, the position of the cap body 3 relative to the sleeve 2 is limited to prevent the cap body 3 from being too deep into the sleeve 2, thereby reducing or eliminating the set gap, or the cap body 3 from being too close to the upper surface of the sleeve 2, thereby increasing the set gap, so that the second plug body no longer has sufficient expansion force to compress the set gap, thereby causing the cover assembly to fail to seal the beverage.

[0050] In order to achieve the axial position fixation of the cap body 3 relative to the sleeve 2, a mechanical matching structure can be used, such as a hook and a snap ring, or the cap body 3-sleeve 2 integral structure can be processed at the same time. However, considering the convenience of engineering implementation, connection stability and implementation cost, in some embodiments, the cap body 3 is fixed to the inside of the sleeve 2 by spot welding, and the number of welding points between the cap body 3 and the sleeve 2 is not less than two.

[0051] In order to take into account both the beverage flow rate of the bottle cap assembly having the titanium sleeve and the cap body in an open state and the sealing performance in a closed state, in some embodiments, the gap is set to be between 0.1 and 1 mm.

[0052] Preferably, in some embodiments, the gap is set to 0.5 mm.

[0053] like Figure 4 As shown, in some embodiments, the first plug body 1 includes:

[0054] The first flange 12 is provided on the upper surface of the first plug body 1 and is configured to extend outwardly along the radial direction of the through hole 11;

[0055] an annular groove 13, provided on one side of the outer peripheral surface of the first plug body 1 close to the lower surface; and

[0056] The vent hole 14 is formed through the outer peripheral surface of the first plug body 1 and communicates with the through hole 11 .

[0057] The above-mentioned first flange 12 can increase the contact area between the first stopper 1 and the beverage container, thereby strengthening the sealing performance between the first stopper 1 and the beverage container; the above-mentioned annular groove 13 can self-compress after the first stopper 1 is inserted into the bottle mouth of the beverage, thereby increasing the contact tightness between the first stopper 1 and the inner wall of the container with a greater compression amount, preventing the beverage from leaking from between the first stopper 1 and the container wall; the above-mentioned vent hole 14 is arranged on the outer peripheral surface of the first stopper 1, and is used to balance the air pressure inside and outside the beverage container when pouring the beverage through the bottle cap assembly having a titanium sleeve and a cap body.

[0058] like Figure 3 As shown, in some embodiments, the sleeve 2 includes:

[0059] A first curling edge 21 is provided on the upper surface of the sleeve 2 and is configured to extend outwardly in the radial direction of the through hole 11; and

[0060] The second curled edge 22 is disposed on the lower surface of the sleeve 2 , and is configured to extend outwardly in the radial direction of the through hole 11 , and fit and cover the lower surface of the first plug body 1 .

[0061] The first curled edge 21 is used to form a guide channel for the beverage to flow out of the bottle cap assembly having the titanium sleeve and the cap body, so that the beverage can be poured outward in a combined form, thereby preventing the beverage from splashing everywhere due to the shape of the outlet, which would bring a bad user experience to consumers; and the second curled edge 22 is arranged on the lower surface of the sleeve 2 and fits and covers the lower surface of the first plug body 1, so as to prevent the beverage from contacting the first plug body 1 and preventing the beverage from penetrating between the first plug body 1 and the sleeve 2.

[0062] like Figure 2 As shown, in some embodiments, the cap body 3 includes:

[0063] The bell mouth 31 is arranged at the opening of the cap body 3 so that the opening area of ​​the cap body 3 increases gradually from bottom to top.

[0064] The bell mouth 31 and the first curled edge 21 together limit the shape of the liquid column of the beverage flowing outward, and form an opening shape that expands outward, making it easier for the second plug to be inserted into the cap body 3.

[0065] Considering that the sleeve 2 and the cap body 3 may contact the beverage in the beverage container, in some embodiments, the sleeve 2 and / or the cap body 3 are made of metal material, and the metal material includes pure titanium or titanium alloy.

[0066] Titanium or titanium alloy has the advantages of high strength, good corrosion resistance, high heat resistance, and good memory. After expanding due to the pressure of the second plug, it can return to its original state in a short time after the second plug is removed. It also has extremely strong biocompatibility and will not have adverse effects on the human body or damage the flavor and taste of the beverage.

[0067] In some embodiments, the first plug body 1 and the second plug body are made of wood material, rubber material or PET material.

[0068] Therefore, according to the embodiment of the present disclosure, by embedding the first plug body 1 in the container mouth of the beverage, and by controlling the second plug body to be inserted into the cap body 3 or taken out from the cap body 3, the container mouth of the beverage can be selectively opened or closed, thereby flexibly controlling the outflow or sealing of the beverage to increase the shelf life of the beverage; by selecting the sleeve 2 and the cap body 3 made of titanium or titanium alloy materials, the first plug body 1 or the second plug body can be prevented from contacting the beverage, so as to maintain the flavor and taste of the beverage flowing out from between the sleeve 2 and the cap body 3, thereby improving the drinking experience and health of beverage consumers.
