Description

Technical Field

[0001] The utility model belongs to the technical field of sealing covers, in particular to a disposable bottled water cover with an aluminum foil sealing film. Background Art

[0002] Currently, disposable bottled water bottles on the market typically use a screw-on lid. Specifically, a sealing ring in the lid clings tightly to the inner wall of the container opening, creating a watertight seal. This structure can also be supplemented with a sealing gasket that clings to the top surface of the container opening for even better sealing.

[0003] However, the cover body of the above structure has certain disadvantages, such as:

[0004] First, the screw-on seal method often features a safety ring at the bottom of the lid. Once the lid is unscrewed, the connection between the lid and the ring is severed, but the ring remains on the barrel to serve as a reminder that the lid has been opened. This structure requires more raw materials, increasing the cost of the lid and impacting market competitiveness.

[0005] Second, because disposable bottled water has a large capacity, with common capacities ranging from 3 to 18L, if it falls or collides during transportation or lifting, a large internal and external pressure difference will be generated, which can easily lead to temporary sealing failure. This will not only cause leakage, but will also easily breed microorganisms and bacteria after long-term storage, affecting hygiene conditions.

[0006] Third, the screw-tight sealing method requires a large amount of force to open the cover, which is inconvenient. Utility Model Content

[0007] The purpose of the utility model is to solve the technical problems of the above-mentioned sealing cover body having high cost and incomplete sealing, and to provide a disposable bottled water cover body with an aluminum foil sealing film to solve the above-mentioned technical problems.

[0008] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0009] A disposable bottled water cover with an aluminum foil sealing film comprises a sealing cover body, wherein the inner wall of the sealing cover body is provided with a screw thread;

[0010] Its characteristics are:

[0011] The top wall of the sealing cover body is provided with a lower pressure ring extending toward the top edge of the barrel opening, and an aluminum foil sealing film for sealing the barrel opening is also provided between the lower pressure ring and the top edge of the barrel opening.

[0012] As a further improvement of the present invention, at least one extension portion is provided around the periphery of the aluminum foil sealing film.

[0013] As a further improvement of the present invention, the side wall inside the sealing cover body is further provided with at least one fragile part extending toward the top edge of the barrel mouth, and the fragile part is close to one side of the extension part and is blocked by the extension part and broken when the sealing cover body is loosened.

[0014] As a further improvement of the present invention, the side wall inside the sealing cover body is further provided with at least one second fragile piece extending toward the barrel opening, and the second fragile piece is close to the other side of the extension portion.

[0015] As a further improvement of the present invention, the first and second fragile parts are columnar.

[0016] As a further improvement of the present invention, at least one side of the lower pressure ring is provided with a plurality of reinforcing ribs connected to the sealing cover body.

[0017] Due to the adoption of the above technical solution, the beneficial effects of the utility model are as follows:

[0018] The traditional sealing method of tightening the lid has been improved to the current sealing method using aluminum foil. When the aluminum foil passes through the electromagnetic wave induction coil, it can instantly heat up to achieve a sealing effect of magnetic heat conversion, which can firmly seal the mouth of the disposable bucket, greatly improving the sealing effect.

[0019] Since the sealing is achieved by the aluminum foil sealing film, the sealing cover body plays a common covering role, and the user can easily open the sealing cover body and tear off the aluminum foil sealing film.

[0020] Moreover, the sealing cover does not need to be equipped with a safety ring, the height of the cover can be greatly reduced, the amount of raw materials used is significantly reduced, and about 30%-40% of the raw materials can be saved. The price of the final product is greatly reduced, and the market competitiveness is higher. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] In order to make the purpose, technical solutions and advantages of this utility model more clear, the following is a brief description of the invention. Figure 1 To the attached Figure 10 The present invention is further described in detail with reference to the following embodiments. However, it should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the scope of the present invention. In addition, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0037] refer to Figures 1 to 3 The sealing caps of traditional disposable bottled water are all sealed by screwing. The tighter the screwing, the better the sealing. The internal sealing ring 102 is tightly fitted on the inner wall of the barrel mouth 2. A sealing cushion 103 can also be added to fit tightly on the top edge of the barrel mouth 2. The sealing effect of this structure of the cover has certain limitations. During transportation and lifting, if the barrel body collides, the internal pressure will break through the seal and cause a temporary leakage, which will affect the shelf life of the water. The safety ring 101 is positioned at the barrel mouth 2. When the traditional sealing cap 100 is opened, the two are disconnected and cannot be repaired or reset.

[0038] Example 1

[0039] This embodiment discloses a disposable bottled water cover with an aluminum foil sealing film, including a sealing cover body 300. The inner wall of the sealing cover body 300 is provided with a screw thread 305, which can be threaded with the thread at the outer periphery of the barrel mouth 2 using the thread 305. This structure is for the purpose of covering the barrel mouth 2 and is consistent with the common cover body connection method.

[0040] refer to Figure 4 The improvement of the present invention is that the top wall of the sealing cap body 300 is provided with a lower pressure ring 301 extending toward the top edge of the bung opening 2 (i.e., the annular surface at the top of the bung opening 2). When the sealing cap body 300 is tightened, the lower pressure ring 301 continuously moves toward the top edge of the bung opening 2. Conversely, when the sealing cap body 300 is loosened, the lower pressure ring 301 and the bung opening 2 gradually separate. Conventional sealing caps, on the other hand, have the sealing ring 102 tightly attached to the inner wall of the bung opening 2.

[0041] In addition, an aluminum foil sealing film 400 for sealing the barrel mouth 2 is provided between the lower pressure ring 301 and the top edge of the barrel mouth 2. Of course, its diameter should be larger than the diameter of the barrel mouth 2 and smaller than the inner diameter of the sealing cover body 300. When the sealing cover body 300 is tightened, it will be screwed down together with the aluminum foil sealing film 400 until the upper and lower directions of the aluminum foil sealing film 400 are clamped by the lower pressure ring 301 and the top edge of the barrel mouth 2. After that, the aluminum foil sealing film 400 can be instantly heated up and fixed to the top edge of the barrel mouth 2 using electromagnetic heating equipment to complete the seal. The sealing cover body 300 only plays a simple covering role and does not need to have a sealing effect.

[0042] Thus, a new sealing method different from the traditional sealing structure is formed, the sealing cover body 300 does not need to be provided with a safety ring 101, its height can be shortened, and the overall material consumption is greatly reduced (comparable to Figure 2 and Figure 6 Moreover, the sealing effect of the aluminum foil sealing film 400 is much better than that of the traditional thread sealing method. Even if a person steps on the bucket, it will not cause leakage, and the sealing effect is qualitatively improved.

[0043] In this embodiment, in order to facilitate people to uncover the aluminum foil sealing film 400, at least one extension portion 401 is provided around the periphery of the aluminum foil sealing film 400. The aluminum foil sealing film 400 can be opened by pinching this portion with fingers and lifting it up with force. In practice, three extension portions 401 are usually evenly arranged. Even if one is damaged, the others can still be used conveniently. In addition, the extension portion 401 has another function, which is to be stuck inside the sealing cover body 300 and not easily fall off. In particular, when the aluminum foil sealing film 400 is placed in the sealing cover body 300 in advance, because its length exceeds the inner diameter of the sealing cover body 300, it will bend to form a snap-on effect (such as Figure 7 、 Figure 9 and Figure 10 As shown), even if the processing equipment flips over the sealing cover body 300, the aluminum foil sealing film 400 will not fall off.

[0044] Example 2

[0045] The purpose of this embodiment is to achieve a reminder effect after the sealing cover body 300 is opened for the first time, to prevent someone from damaging or contaminating the barrel mouth 2 and other locations after opening the sealing cover body 300, and then reinstalling it without being noticed, causing the user to be unaware and affecting the hygiene condition.

[0046] Specifically, with this structure, the sealing cap body 300 no longer functions as a screw-on seal, but rather simply covers the bung opening 2. Consequently, the sealing cap body 300 does not need to be provided with the safety ring 101, which could easily lead to malicious or unintentional opening of the bung opening 2. For example, if the sealing cap body 300 is opened, contamination could occur at the bung opening 2. Even if the water in the bung is uncontaminated, the contaminated area could be easily exposed when the aluminum foil sealing film 400 is opened to pour out the water, without the user being able to tell that the sealing cap body 300 has been previously opened.

[0047] refer to Figures 5 to 8 To prevent this from happening, the inner sidewall of the sealing cap body 300 is further provided with at least one breakable member 303 extending toward the top edge of the bunghole 2. This member 303 utilizes a breakable connection, is no higher than the top edge of the bunghole 2, and is located close to the outer wall of the bunghole 2. Furthermore, the breakable member 303 is located near one side of the extension 401, so that the two are in close proximity or contact with each other. When the sealing cap body 300 is loosened, the breakable member 303 is blocked by the extension 401 and breaks.

[0048] In other words, only when the sealing cap body 300 is loosened and opened will the fragile member 303 break or crack and deform. At this point, the user will feel a distinct tactile sensation and hear a clear "snap" sound (i.e., the sound of breaking), reminding the user that the sealing cap body 300 has been opened for the first time and that drinking is safe. Because the aluminum foil sealing film 400 contains aluminum, the fragile member 303 is easily broken. Furthermore, the aluminum foil sealing film 400 contacts the fragile member 303 with its side, and the internal space is extremely limited. The aluminum foil sealing film 400 is also not prone to bending or slipping, and can contact the fragile member 303 in a flat state, thus easily breaking and deforming it.

[0049] When placing the aluminum foil sealing film 400, the extension portion 401 can be placed on one side of the fragile part 303 (refer to Figure 9 ), which also serves as a mutual limit and support between the two. As the sealing cap body 300 is continuously tightened and lowered, the aluminum foil sealing film 400 rotates and lowers along with it. When it contacts the top edge of the bunghole 2, that is, when it is fully tightened, the aluminum foil sealing film 400 clamps the sealing cap body 300 and the top edge of the bunghole 2 together, and the sealing cap body 300 cannot be tightened and lowered. After electromagnetic heating, the aluminum foil sealing film 400 is firmly adhered to the top edge of the bunghole 2.

[0050] When the user is ready to open the bottle for drinking, the aluminum foil sealing film 400 is firmly attached to the top edge of the barrel opening 2, while the sealing cover body 300 can be loosened. This creates a dynamic and static connection between the aluminum foil sealing film 400 and the sealing cover body 300, i.e., the sealing cover body 300 is loosened while the aluminum foil sealing film 400 remains stationary. At this point, the breakable piece 303 is blocked by the extension 401 and breaks or cracks, producing a crisp "snap" sound. Of course, providing multiple breakable pieces 303 will produce multiple "snap" sounds, thereby reminding the user that the sealing cover body 300 has been opened. After tightening the sealing cover body 300 again and opening it a second time, no sound is emitted, or the user experiences no or very little jerking sensation, thus reminding the user that the sealing cover body 300 has been opened and that they need to pay attention to hygiene.

[0051] In this embodiment, the inner sidewall of the sealing lid body 300 may also be provided with at least one second breakable member 304 extending toward the barrel opening 2, with the second breakable member 304 located near the other side of the extension 401. In other words, the extension 401 is provided with breakable members on both opposing sides. The first breakable member 303 serves as an anti-theft reminder when loosening the lid, while the second breakable member 304 acts as a positional support for the extension 401. This serves to limit and support the aluminum foil sealing film 400 when initially inserted into the sealing lid body 300, preventing it from falling. Of course, when the sealing lid body 300 is tightened again after opening, it may prematurely come into contact with the second extension 304, causing it to break or crack, further alerting the user that the lid has been opened.

[0052] The first and second breakable members 303 and 304 are cylindrical, and their connection with the sealing cover body 300 is a breakable connection. Of course, they can also be plate-shaped, sheet-shaped, or other shapes, as long as they are a breakable connection.

[0053] As a further improvement of the present invention, at least one side of the lower pressure ring 301 is provided with a plurality of reinforcing ribs 302 connected to the sealing cover body 300, which can support the lower pressure ring 301, prevent it from being offset due to excessive force, and ensure its upper and lower corresponding relationship with the top edge of the barrel mouth 2.

[0054] Working principle:

[0055] First, the aluminum foil sealing film 400 needs to be pre-placed into the sealing cover body 300, and the extension portion 401 and the fragile part 1 303 are close to each other, and the two can form a mutual limiting support effect to prevent the sealing cover body 300 from separating and falling off when turning over.

[0056] The sealing cap body 300 is then tightened. Because the aluminum foil sealing film 400 is held in place within the body 300, it rotates with it until the foil sealing film 400 contacts the top edge of the bung opening 2. At this point, the sealing cap body 300 cannot be tightened. As the bung opening 2 passes through the electromagnetic heating device, the foil sealing film 400 is instantly melted to the top edge of the bung opening 2 by the high temperature, creating a complete seal. The sealing cap body 300 merely serves to cover the bung opening 2 and the foil sealing film 400.

[0057] When the sealing cover body 300 is first opened, the aluminum foil sealing film 400 is in a fixed connection state, and the fragile part 1 303 will be limited and blocked by the extension part 401 therein. Only when a certain force is reached will the fragile part 1 303 be irreparably damaged, such as being disconnected (such as Figure 10 ) or cracking, at this time the hand will have a clear sense of resistance and a "snap" sound can be heard.

[0058] Due to the adoption of the above technical solution, the beneficial effects of the utility model are as follows:

[0059] The traditional sealing method of tightening the lid has been improved to the current sealing method using aluminum foil. When the aluminum foil passes through the electromagnetic wave induction coil, it can instantly heat up to achieve a sealing effect of magnetic heat conversion. It can firmly seal the mouth of the disposable bucket, greatly improving the sealing effect. Even if people step on it, it will not cause leakage.

[0060] Since the sealing is achieved by the aluminum foil sealing film, the sealing cover body plays a common covering role, and the user can easily open the sealing cover body and tear off the aluminum foil sealing film.

[0061] Moreover, the sealing cover does not need to be equipped with a safety ring, the height of the cover can be greatly reduced, the amount of raw materials used is significantly reduced, and about 30%-40% of the raw materials can be saved. The price of the final product is greatly reduced, and the market competitiveness is higher.

[0062] While the present invention has been described above with reference to exemplary embodiments, various modifications may be made and equivalent components may be substituted without departing from the scope of the present invention. In particular, as long as no structural conflicts exist, the various features of the disclosed embodiments may be combined with one another in any manner. The omission of an exhaustive description of these combinations in this specification is solely for the sake of space and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions within the scope of the claims.
