Description

Technical Field

[0001] The invention relates to the field of bottle caps, in particular to a sealed bottle cap and a sealed bottle. Background Art

[0002] As the sealing part of the bottle, the bottle cap is an important part of the liquid container packaging. For companies such as wine, perfume, medicine, chemical liquid, etc., the anti-counterfeiting of packaging bottles is very important.

[0003] Bottles that fail to pass the anti-counterfeiting test, such as wine bottles, can be easily recycled by criminals to make fake wine. This makes the market full of low-priced fake wine, impacting the real wine market, and causing great reputation damage to wine production companies, affecting the development of enterprises. At the same time, drinking fake wine can cause great damage to people's health, especially fake liquor mixed with industrial alcohol, which can also cause life-threatening.

[0004] However, the existing bottle cap structure has certain defects, resulting in poor sealing of the bottle. When the bottle is tilted, inverted or shaken, some liquid is likely to overflow from the bottle mouth. Although the external packaging can prevent the wine from spilling directly from the bottle mouth to a certain extent, there will still be liquid accumulation in the gap between the bottle mouth and the bottle cap and overflow when it is opened. In addition, when the wine bottle cap is assembled on the wine bottle, some technical means can still be used to fill the wine bottle with some other liquid without almost destroying the overall structure of the wine bottle cap, thereby counterfeiting and passing off inferior goods as good ones. Summary of the invention

[0005] Based on this, it is necessary to address the technical problem that the sealing of the bottle in the prior art is poor, which causes the liquid in the bottle to easily overflow and cause waste. The present invention provides a sealed bottle cap and a sealed bottle.

[0006] The invention discloses a sealed bottle cap, which comprises an inner sleeve, an inner cover and a sealing component.

[0007] The inner sleeve is fixedly sleeved on the bottle mouth of a bottle. An opening is formed on the top of the inner sleeve.

[0008] The inner cover is detachably connected to the inner sleeve.

[0009] The sealing assembly is arranged inside the inner sleeve. The sealing assembly includes an inner plug and a sealing valve. The top of the inner plug is clamped with the inner sleeve, and the bottom is plugged into the inner wall of the bottle mouth. The inner plug is provided with a channel connected to the bottle. The top of the sealing valve passes through the opening and abuts against the inner cover. The bottom end of the sealing valve covers the inner plug to block the channel, and forms a sealing structure of the bottle mouth with the inner plug.

[0010] The sealing valve includes a cover plate, a resistance section and a plug-in section. The top surface of the cover plate is fixedly connected to the resistance section. The top of the resistance section passes through the opening and resists the inner cover, and the diameter of the resistance section is smaller than the diameter of the opening. The bottom surface of the cover plate contacts but is not fixed to the top end surface of the inner plug. The plug-in section is fixedly connected to the center of the bottom surface of the cover plate, and the plug-in section extends into the channel and is located in the bottle mouth.

[0011] As a further improvement of the above scheme, the inner cover includes an integrally connected cover body 1, a cover body 2 and a baffle. The inner side of the cover body 1 is threadedly connected to the inner sleeve. The bottom of the cover body 2 penetrates the cover body 1 and contacts the inner sleeve. The baffle is integrally connected to the inner wall of the cover body 2. The bottom surface of the baffle contacts and abuts against the top of the abutting section.

[0012] As a further improvement of the above scheme, the inner plug includes a first sleeve. The outer side of the first sleeve is clamped on the inner wall of the inner sleeve. The second sleeve is coaxially fixedly connected to the bottom of the first sleeve. The outer wall of the second sleeve is in contact with the inner wall of the bottle mouth, and the inner cavity of the second sleeve forms a channel. The cover plate covers the top of the second sleeve.

[0013] As a further improvement of the above solution, the portion where the top of the second sleeve contacts the sealing valve is bent obliquely upward, and the second sleeve is an elastic structure that deforms when subjected to external force. When the inner cover is assembled on the inner sleeve, the baffle abuts against the abutment section, so that the cover presses down the top of the second sleeve and causes the bend to deform elastically.

[0014] As a further improvement of the above solution, a plurality of anti-slip keys are arranged on the outer side of the inner cover.

[0015] The sealed bottle cap further comprises: an outer cover. The outer cover is fixedly sleeved on the outside of the inner cover. A plurality of anti-slip keys 2 corresponding to the anti-slip keys 1 are arranged on the inner wall of the outer cover. The anti-slip keys 1 and 2 are both arranged vertically, and when the outer cover is matched with the inner cover, the anti-slip keys 1 and 2 are meshed with each other.

[0016] As a further improvement of the above solution, the sealed bottle cap further comprises: an outer sleeve, which is fixedly sleeved with the outer edge of the bottom of the inner sleeve, and the top of the outer sleeve abuts against the bottom of the outer cover.

[0017] As a further improvement of the above solution, the plug-in section is composed of a plurality of flat plates perpendicular to the horizontal plane. The plurality of flat plates are distributed in a circle around the central axis of the cover plate, so that when the plug-in section extends into the channel, the channel is divided into a plurality of flow spaces with fan-shaped cross sections and evenly distributed.

[0018] As a further improvement of the above solution, two flat plates are provided, and the two flat plates are arranged in a cross shape, thereby dividing the channel into four circulation spaces.

[0019] As a further improvement of the above solution, the opening is arranged at the center of the top of the inner sleeve. The top of the inner sleeve is also provided with a plurality of flow holes around the opening.

[0020] The present invention also discloses a sealed bottle, which comprises: a bottleneck and a bottle cap. A bottle mouth is arranged on the top of the bottleneck. The bottle cap covers the bottle mouth. The bottle cap adopts any of the sealed bottle caps mentioned above.

[0021] Compared with the prior art, the technical solution disclosed in the present invention has the following beneficial effects:

[0022] 1. The sealed bottle cap is provided with a sealing assembly inside the inner sleeve. When the inner cover is assembled on the inner sleeve, the baffle can press the abutment section, so that the entire cover is tightly covered on the inner plug, and the channel in the center of the inner plug is blocked by the sealing valve, so that the liquid can neither flow between the inner plug and the bottle mouth nor flow through the channel in the center of the inner plug. And due to the effect of the baffle, as long as the inner cover is not removed from the inner sleeve, it can resist the sealing valve and maintain a continuous sealing effect. This not only ensures that the liquid inside the bottle is not easy to spill from the bottle mouth when it is shaken, laid flat or inverted, but also that there will be no liquid left inside the lid after opening, avoiding waste and pollution of the liquid. It also effectively increases the difficulty of filling and replacing the liquid from the outside of the bottle into the bottle, further improving the anti-counterfeiting performance of the bottle.

[0023] 2. The second sleeve of the sealed bottle cap inner plug can produce elastic deformation when subjected to external force. By pressing down the cover plate, the top end of the second sleeve is deformed, thereby providing a pre-tightening force for the cover plate when the bottle cap is in a sealed state, thereby playing a role similar to an interference fit, making the cover between the sealing valve and the inner plug tighter, further improving the sealing performance of the bottle.

[0024] 3. The beneficial effects of the sealed bottle are the same as those of the sealed bottle cap described above, and will not be described in detail here. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present invention belongs. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "or / and" used herein includes any and all combinations of one or more of the related listed items.

[0043] Example 1

[0044] See also Figures 1 to 4 The present embodiment provides a sealed bottle cap, which covers the mouth of a bottle. The neck of the bottle may be provided with an annular groove that is easy to break. The sealed bottle cap comprises: an inner sleeve 3, an inner cover 2 and a sealing assembly 5. In the present embodiment, the bottle cap may further comprise an outer cover 1, an inner sleeve 3, an outer sleeve 4, a limiting ring 6, a welding ring 7, a transparent cover 8 and an information carrier 9.

[0045] Please combine Figure 5 The outer cover 1 is the main part of the bottle cap. Normal consumers generally open the bottle by twisting the outer cover 1 to get the liquid inside the bottle. In this embodiment, the outer shape of the outer cover 1 can be designed to be spherical. Of course, in other embodiments, the outer shape of the outer cover 1 can also be set to a cylindrical, prismatic, etc. shape, as long as it can have a sealed inner cavity and is easy to twist. The outer surface sidewall of the outer cover 1 can also be selectively provided with anti-slip textures.

[0046] Please combine Figure 6 and Figure 7 , the inner cover 2 is coaxially fixedly connected to the inside of the outer cover 1. In this embodiment, the inner cover 2 can be fixed to the outer cover 1 by a welding ring 7. The welding ring 7 is arranged between the inner cover 2 and the outer cover 1. The inner side of the welding ring 7 is welded to the inner cover 2, and the outer side is welded to the outer cover 1, thereby realizing the coaxial fixed connection between the outer cover 1 and the inner cover 2. The inner cover 2 can also adopt a transparent structure in this embodiment. It should be noted that in the actual assembly process of the bottle cap, before the outer cover 1 and the inner cover 2 are welded and assembled, an information carrier 9 for anti-counterfeiting and / or lottery can be filled between the two.

[0047] Among them, the outer side of the inner cover 2 can be provided with a plurality of anti-slip keys 1, and the inner wall of the outer cover 1 can be provided with a plurality of anti-slip keys 2 corresponding to the anti-slip keys 1; wherein the anti-slip keys 1 and the anti-slip keys 2 are both arranged vertically, and when the outer cover 1 and the inner cover 2 are matched, the anti-slip keys 1 and the anti-slip keys 2 are meshed with each other. In addition, the anti-slip keys 1 and the anti-slip keys 2 can be evenly distributed. In this way, when the outer cover 1 is put on the inner cover 2, the two will not rotate relative to each other, which is convenient for the subsequent welding process and can also enhance the fixing strength after welding.

[0048] In this embodiment, the transparent cover 8 can be arranged inside the outer cover 1, and the top of the outer surface of the transparent cover 8 is embedded in the through hole opened at the top of the outer cover 1. The top of the inner surface of the transparent cover 8 can form a coin-like interlayer space with the inner cover 2. The information carrier 9 can be assembled in this interlayer space. The upper and lower surfaces of the information carrier 9 can be provided with a two-dimensional code. The two-dimensional code located on the top surface can be used to be scanned and identified by the user to query the authenticity of the product or the place of origin and other public information. The two-dimensional code located on the bottom surface can only be observed from the bottom of the inner cover 2 after the bottle cap is opened normally. The two-dimensional code can be used to be scanned by consumers, so as to carry out one-time activities such as lottery or exchange. The top and bottom surfaces of the information carrier 9 can be closely fitted with the transparent cover 8 and the outer cover 1 respectively. In other embodiments, the information carrier 9 can also have a built-in NFC identification chip, and the user can also sense and identify the public information by approaching the bottle cap with a mobile phone supporting NFC function.

[0049] In this embodiment, the information carrier 9 can be first placed inside the transparent cover 8, and then the transparent cover 8 can be placed inside the outer cover 1, and the end of the transparent cover 8 can be embedded in the through hole on the outer cover 1. Then the welding ring 7 can be put on the bottom of the inner cover 2, and then the top of the inner cover 2 can be filled into the outer cover 1, so that the top of the inner cover 2 can contact the information carrier 9 and fit tightly. After that, the outer cover 1 and the inner cover 2 can be fixed by the welding ring 7 using ultrasonic welding technology, and the information carrier 9 and the transparent cover 8 can also be firmly fixed inside the outer cover 1.

[0050] Please combine Figure 8 To further explain the function of the inner cover 2, the inner cover 2 may further include a cover body 1 21, a cover body 22 and a baffle 23. The cover body 1 21, the cover body 22 and the baffle 23 may be integrally formed by injection molding. The baffle 23 is integrally connected to the inner wall of the cover body 22. A section of thread may be provided on the inner side of the cover body 1 21. The bottom of the cover body 22 passes through the cover body 1 21 and contacts the inner sleeve 3.

[0051] Please combine Fig. 9, the inner sleeve 3 is detachably connected to the inner cover 2. Specifically, a thread matching the inner wall of the cover body 21 may be provided on the outer side of the inner sleeve 3 near the top. Therefore, the inner sleeve 3 may be threadedly connected to the cover body 21, thereby realizing a detachable connection between the inner sleeve 3 and the inner cover 2. After the outer cover 1 and the inner cover 2 are welded, they may be sleeved together on the outer edge of the top of the inner sleeve 3. In addition, in this embodiment, an opening 31 is provided in the center of the top of the inner sleeve 3, and flow holes arranged at intervals may also be provided at the edge. The liquid in the bottle may flow out from the flow holes on the inner sleeve 3, or from the opening 31 in the center thereof. The inner wall of the inner sleeve 3 may also be provided with an annular clamping groove.

[0052] Please combine Fig.10 The sealing assembly 5 is arranged inside the inner sleeve 3. The sealing assembly 5 includes an inner plug 51 and a sealing valve 52.

[0053] The top of the inner plug 51 is engaged with the inner sleeve 3, and the bottom is plugged into the inner wall of the bottle mouth, which preliminarily improves the sealing of the bottle. The inner plug 51 can be provided with a channel running through the top and bottom as shown in the figure, and the channel can be connected to the inside of the bottle. The top of the sealing valve 52 passes through the opening 31 on the inner sleeve 3 and abuts against the inner cover 2. The bottom end of the sealing valve 52 covers the inner plug 51 to block the above-mentioned channel, and forms a sealing structure of the bottle mouth with the inner plug 51, further improving the sealing of the bottle.

[0054] In this embodiment, the inner plug 51 may include a first sleeve 511 and a second sleeve 512. A snap ring is integrally connected to the outer side of the first sleeve 511. The snap ring is snapped into the snap groove to fix the inner plug 51 and the inner sleeve 3. A bent lip plate 513 is also integrally connected to the outer edge of the bottom end of the first sleeve 511. The lip plate 513 fits on the end surface of the top of the bottle, so that when the inner plug 51 is plugged on the bottle mouth, it provides better sealing for the corner between the inner wall of the bottle mouth and the top of the bottle mouth, and can also prevent the inner plug 51 from falling into the bottle from the bottle mouth. The second sleeve 512 is coaxially fixedly connected to the bottom of the first sleeve 511. The outer wall of the second sleeve 512 fits the inner wall of the bottle mouth, and the inner cavity of the second sleeve 512 constitutes a channel. Among them, the sealing valve 52 covers the top of the second sleeve 512.

[0055] In this embodiment, the outer wall of the second sleeve 512 can be provided with a plurality of anti-skid rings distributed in a stepped manner at intervals. The plurality of anti-skid rings are arranged parallel to each other. Each anti-skid ring is connected to the second sleeve 512 in one piece. When the inner plug 51 is plugged in the bottle mouth, the plurality of anti-skid rings can make the inner plug 51 produce an interference fit with the inner wall of the bottle mouth, and then be tightly plugged in the bottle mouth, thereby improving the sealing performance. In addition, the part where the top of the second sleeve 512 contacts the sealing valve 52 is bent obliquely upward, and the second sleeve 512 is an elastic structure that deforms when subjected to external force. In this way, when the inner cover 2 is assembled on the inner sleeve 3, the baffle 23 abuts against the abutment section 522, so that the cover plate 521 presses down the top of the second sleeve 512 and causes its bending shape to produce elastic deformation, which can also play a role similar to interference fit, so that the sealing valve 52 and the inner plug 51 are more tightly covered.

[0056] The sealing valve 52 may include a cover plate 521, a resistance section 522 and an insertion section 523. The top surface of the cover plate 521 is fixedly connected to the resistance section 522. The top of the resistance section 522 passes through the opening 31 and resists the inner cover 2, and the diameter of the resistance section 522 is smaller than the aperture of the opening 31. The bottom surface of the cover plate 521 contacts but is not fixed to the top end surface of the second sleeve 512. The insertion section 523 is fixedly connected to the center of the bottom surface of the cover plate 521, and the insertion section 523 extends into the channel and is located in the bottle mouth.

[0057] In this way, when the outer cover 1 and the inner cover 2 are assembled on the inner sleeve 3, the baffle 23 can press the abutment section 522, so that the entire cover 521 tightly covers the inner plug 51, and then the channel at the center of the inner plug 51 is blocked by the sealing valve 52, and the liquid can neither flow between the inner plug 51 and the bottle mouth, nor flow from the channel in the center of the inner plug 51. And due to the effect of the baffle 23, as long as the inner cover 2 is not removed from the inner sleeve 3, it can resist the sealing valve 52 to maintain the sealing effect, avoiding the displacement of the sealing valve 52 due to external forces such as shaking, thereby effectively improving the sealing effect of the bottle. Not only can it ensure that the internal liquid is not easy to spill during the transportation of the bottle, but it can also effectively increase the difficulty of filling and replacing the liquid from the outside of the bottle into the bottle, further improving the anti-counterfeiting performance of the bottle.

[0058] When ordinary consumers twist the outer cover 1 together with the inner cover 2 to separate from the inner sleeve 3, the top of the sealing valve 52 loses the contact of the baffle 23, so when the bottle is tipped, the sealing valve 52 is affected by gravity or the impact of the liquid in the bottle, causing relative shaking with the inner plug 51, thereby canceling the seal on the bottle mouth, and the liquid in the bottle can flow out normally from the channel in the center of the inner plug 51. Of course, when the inner cover 2 is put back on the inner sleeve 3 again, the baffle 23 can still play the original contact role, and the sealing structure can still continue to produce a sealing effect.

[0059] In this embodiment, the plug-in section 523 is composed of a plurality of flat plates perpendicular to the horizontal plane, and the plurality of said flat plates are distributed in a circular manner around the central axis of the cover plate 521, so that when the plug-in section 523 extends into the channel, the channel is divided into a plurality of circulation spaces with fan-shaped cross sections and evenly distributed. Two flat plates can be provided, and the two flat plates are arranged in a cross-shaped manner, so as to divide the channel into four said circulation spaces. In this way, when the plug-in section 523 extends into the channel, it will not easily cause blockage of the channel as a cylindrical plug-in, and can play a positioning role similar to the "root" for the cover plate 521.

[0060] Please combine Fig.11 and Fig.12 The limiting ring 6 is arranged on the inner side of the inner sleeve 3. The top of the limiting ring 6 is fixedly connected to the inner sleeve 3. A plurality of latch teeth 61 are fixedly connected to the circumference of the inner wall of the limiting ring 6.

[0061] In this embodiment, the limit ring 6 and the plurality of latch teeth 61 can be an integrally formed structure. One end of each latch tooth 61 is connected to the inner wall of the limit ring 6, and the other end is inclined to the axis of the limit ring 6 and is arranged upward, and the limit ring 6 and the latch teeth 61 can be made of a metal material with high rigidity such as aluminum alloy, iron, and stainless steel. Specifically, a "Π" shape can be cut on the limit ring 6 first, and then the cut portion can be stamped toward the inside of the limit ring 6 to form a plurality of integral latch teeth 61. After the limit ring 6 is processed, its top can be integrally connected with the inner sleeve 3 by injection molding, which effectively improves the structural strength of the fixed connection between the two.

[0062] When the bottle cap is assembled on the bottle mouth, the multiple latch teeth 61 can abut against the annular groove and are used to limit the axial movement of the inner sleeve 3 when the inner sleeve 3 is assembled on the bottle mouth, thereby preventing the inner sleeve 3 from being separated from the bottle mouth. When the inner sleeve 3 is pried by external force, the latch teeth 61 are forced to break the annular groove, so that the bottle mouth together with the inner sleeve 3, the limit ring 6 and the sealing component 5 are separated from the bottle neck, that is, the bottle neck structure of the bottle is destroyed, preventing the situation of filling and replacing liquid into the bottle by taking off the entire bottle cap without destroying the bottle body structure, effectively increasing the difficulty and cost of counterfeiting, thereby further improving the anti-counterfeiting performance of the bottle.

[0063] The outer sleeve 4 is fixedly connected to the outer edge of the bottom of the inner sleeve 3. The top of the outer sleeve 4 abuts against the bottom of the outer cover 1. In this embodiment, two groups of anti-counterfeiting teeth 10 are also fixedly connected to the top of the outer sleeve 4. The bottom of the outer cover 1 is provided with receiving grooves 11 corresponding to the anti-counterfeiting teeth 10. Each group of anti-counterfeiting teeth 10 is located in the corresponding receiving groove 11.

[0064] When consumers open the bottle cap normally, they twist the outer cap 1 to generate relative movement between the outer cap 1 and the outer cover 4, so that each set of anti-counterfeiting teeth 10 is sheared by the outer cap 1 and breaks off from the outer cover 4, thereby playing an anti-counterfeiting role in identifying that the bottle cap has been opened. In this embodiment, the number of tooth blocks of each set of anti-counterfeiting teeth 10 can be set to three.

[0065] Example 2

[0066] This embodiment provides a method for assembling a sealed bottle cap, through which the various components of the bottle cap in Embodiment 1 can be assembled and assembled together on the bottle.

[0067] The assembly method comprises the following steps:

[0068] (1) The welding ring 7 is placed on the bottom of the inner cover 2, and then the inner cover 2 is threadedly connected to the inner sleeve 3 on which the limiting ring 6 has been integrally injection-molded, thereby forming a combined body.

[0069] (2) Insert the bottom of the assembly 1 (i.e., the bottom of the inner sleeve 3) into the outer sleeve 4 to fix it, thereby forming the assembly 2.

[0070] (3) Place the information carrier 9 into the transparent cover 8, and then fill the transparent cover 8 into the outer cover 1, so that the end of the transparent cover 8 is embedded in the through hole of the outer cover 1.

[0071] (4) The top of the second assembly (i.e., the top of the inner cover 2) is filled into the outer cover 1, so that the top of the inner cover 2 contacts the information carrier 9 and fits tightly, and then the outer cover 1 and the inner cover 2 are fixed by the welding ring 7 using ultrasonic welding technology.

[0072] (5) Cover the sealing valve 52 on the inner plug 51, and then clamp the top of the inner plug 51 into the inner sleeve 3 to form an integral bottle cap, thereby completing the assembly of the bottle cap.

[0073] (6) Place the assembled bottle cap just above the bottle mouth, and move the bottle cap toward the bottle mouth by using a stamping technique. During this process, the latching teeth 61 are squeezed by the outer wall of the bottle neck until they fall into the annular groove to reset and abut against the annular groove, thus completing the assembly of the bottle cap and the bottle neck.

[0074] Example 3

[0075] This embodiment provides a sealed bottle, which includes a bottleneck and a bottle cap.

[0076] The top of the bottle neck is provided with a bottle mouth and the bottle neck is provided with an annular groove which is easy to break.
