Description

Technical Field

[0001] This utility model belongs to the technical field of disposable bottled water caps, and particularly relates to disposable bottled water pressure caps. Background Technology

[0002] Large-capacity drinking water buckets can be broadly categorized into reusable buckets (such as the 18.9-liter blue bucket, with thick walls that are difficult to deform) and disposable buckets (such as transparent buckets with handles, with thin walls that are easily deformed).

[0003] Disposable, large-capacity bottled water is quite common, with thinner walls that can be discarded after use. To achieve a better seal, aluminum foil is used to seal the opening before tightening the cap. This seal is more effective than a traditional cap alone. Chinese utility model patent CN223315539U discloses a disposable bottled water cap with an aluminum foil sealing film, which reduces material usage and provides an irreparable opening indicator to prevent accidental damage.

[0004] However, the above structure achieves a sealing effect through aluminum foil film, with the lid only serving a covering function. During transportation, to increase the capacity per shipment and improve stability, the buckets are laid horizontally and then stacked in an alternating pattern. The reason for using the horizontal placement method is that vertically stacked buckets would cause the upper part of the bucket to be flattened and deformed, and this deformation would be irreversible and affect sales; therefore, the buckets are always stacked horizontally.

[0005] The bottom bucket experiences the greatest pressure. Combined with the bumps during transportation, the aluminum foil bulges under pressure. In addition, there is a gap between the aluminum foil and the lid. When the pressure reaches a certain value, the aluminum foil will break (including the aluminum foil breaking at the joint where it is glued to the bucket opening, or any crack on the surface of the aluminum foil), causing water leakage. Therefore, the high breakage rate has not been completely resolved.

[0006] Therefore, it is necessary to design a lid that can effectively withstand pressure on disposable water buckets sealed with aluminum foil to solve the technical problem of easy breakage and leakage of aluminum foil under pressure. Utility Model Content

[0007] The purpose of this invention is to solve the technical problem of leakage caused by easy breakage of the aluminum foil film of disposable water buckets under pressure, and to provide a pressure-bearing cover for disposable bottled water to solve the above-mentioned technical problem.

[0008] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A disposable bottled water pressure cap includes a sealing cap body, the inner wall of which is provided with screw threads, the top wall of which is provided with a downward pressure ring extending toward the top edge of the bottle opening, and an aluminum foil sealing film for sealing the bottle opening is provided between the downward pressure ring and the top edge of the bottle opening. The top wall inside the sealing cover body is also provided with a pressure-bearing structure extending toward the aluminum foil sealing film, and the bottom surface height of the pressure-bearing structure is the same as the top surface height of the aluminum foil film.

[0009] As a further improvement of this utility model, the top of the sealing cover body is provided with a corresponding break-open top cover, and the bottom height of the break-open top cover is consistent with the top height of the aluminum foil film.

[0010] As a further improvement of this utility model, the pressure-bearing structure is at least one pressure-bearing ring.

[0011] As a further improvement of this utility model, the pressure-bearing ring is concentrically corresponding to the sealing cover body.

[0012] As a further improvement of this utility model, the plurality of pressure-bearing rings are evenly distributed in all directions around the center of the sealing cover body.

[0013] As a further improvement of this utility model, the pressure-bearing structure consists of several ribs, which are evenly distributed around the center of the sealing cover body.

[0014] As a further improvement of this utility model, the pressure-bearing structure consists of several pressure-bearing columns, which are evenly distributed around the center of the sealing cover body.

[0015] Due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows: By adding a pressure-bearing structure to support the aluminum foil sealing film, the pressure is distributed to the sealing cap body, thereby improving the pressure-bearing capacity of the aluminum foil sealing film and ensuring that it will not be damaged by pressure during transportation. The actual breakage rate after use is almost zero. Secondly, the bottom height of the broken top cover can be set to be the same as the top height of the aluminum foil film, so that the aluminum foil film is also subjected to pressure from the center, further improving the pressure-bearing effect.

[0016] By effectively improving the existing sealing cap, better pressure resistance can be achieved while controlling the amount of raw materials, and costs can be controlled. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the following is a summary description. Figure 1 To be continued Figure 9 The present invention will be further described in detail with reference to 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. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present invention.

[0020] First, please refer to Figure 8 and Figure 9 The diagram shown illustrates the existing technology structure in order to provide a more intuitive and targeted understanding of the shortcomings of the existing technology.

[0021] Figure 8 The structure shown is that of an existing product sealing cap. Since the aluminum foil film serves a sealing function, the sealing cap is mainly used to cover the barrel opening. The lower pressure ring 101 can also be used to press the aluminum foil film to a certain extent to further improve its sealing performance. However, the dotted circle in the figure marks the gap. There is no structure to support the aluminum foil film 3 here. That is, the aluminum foil film is only thermally bonded to the top edge of the barrel opening by ultrasonic welding or electromagnetic welding, leaving a certain amount of deformation space above it. Figure 9As shown, when water buckets are laid horizontally and stacked one on top of the other, the aluminum foil film (circular, approximately 55mm in diameter and 0.2mm-0.5mm thick) at the opening of the bottom bucket can withstand a maximum pressure of about 130KG. Exceeding this value, the aluminum foil film is easily damaged, and this does not even consider the impact of bumps during transport. Therefore, to solve the problem of damage and leakage, either the number of stacked buckets should be reduced, or double or multi-layer supports should be added to the vehicle to control the number of stacked buckets. However, both methods have drawbacks, such as reduced capacity per vehicle or increased loading time and cost.

[0022] In other words, the aluminum foil film 3 in traditional products not only needs to achieve the function of sealing, but also needs to withstand the pressure generated by stacking.

[0023] Example 1 refer to Figures 1 to 7 This embodiment discloses a disposable bottled water pressure cap, including a sealing cap body 100. The inner wall of the sealing cap body 100 is provided with a screw thread 102. The top wall inside the sealing cap body 100 is provided with a pressure ring 101 extending toward the top edge of the bottle opening 4. An aluminum foil sealing film 3 for sealing the bottle opening 4 is provided between the pressure ring 101 and the top edge of the bottle opening 4. The pressure ring 101 corresponds vertically to the top edge of the bottle opening 4 and can apply a certain pressure to the aluminum foil sealing film 3. This structure is based on the utility model patent with announcement number CN223315539U.

[0024] The improvement is as follows: the top wall inside the sealing cap body 100 is further provided with a pressure-bearing structure 200 extending towards the aluminum foil sealing film 3, which can effectively support the aluminum foil sealing film 3, thereby dispersing the pressure it receives onto the sealing cap body 100; the bottom surface height of the pressure-bearing structure 200 is the same as the top surface height of the aluminum foil film 3, making the deformability of the aluminum foil sealing film 3 smaller. Of course, a small gap can exist between the two, but it is preferable that they are horizontally fitted together. With this structure, when the water bucket is placed horizontally (e.g., ... Figure 4 When the pressure from above acts on the aluminum foil sealing film 3, the pressure-bearing structure effectively supports the aluminum foil sealing film 3, and the pressure is distributed to the sealing cap body 100, thereby ensuring that the aluminum foil sealing film 3 will not be deformed significantly and damaged, and the water bucket itself will not be deformed significantly, thus effectively controlling the damage rate.

[0025] This invention supports the aluminum foil sealing film by adding a pressure-bearing structure, distributing the pressure to the sealing cap body (which is then threaded and fastened to the barrel opening), thereby improving the pressure-bearing capacity of the aluminum foil sealing film and ensuring that it will not be damaged by pressure during transportation. The actual breakage rate after use is almost zero.

[0026] After the improvement, the pressure resistance of the existing aluminum foil film 3 (whose diameter, thickness, and other parameters remain unchanged) is increased to approximately 240KG. In other words, the bottom bucket can withstand greater pressure, more buckets can be stacked, the transport capacity of a single vehicle is increased, no other support frame is needed, and the breakage rate is almost eliminated.

[0027] Of course, the inner top surface of the sealing cap body 100 can also be thickened to form a flat surface to fit the top surface of the aluminum foil film 3, which can also achieve a good pressure-bearing effect. However, this extensive material stacking method will significantly increase the amount of raw materials used, and the cost will increase by at least 40%, directly affecting the market competitiveness of the product and failing to achieve the best performance with the least amount of material.

[0028] Example 2 This embodiment is an improvement on Embodiment 1, and the similarities will not be repeated.

[0029] refer to Figures 1 to 7 In this embodiment, the top of the sealing cap body 100 may also be provided with a concentrically corresponding split top cap 103. This component is for easy insertion into the smart seat of the water dispenser after inversion. Traditional products also include this split top cap 103, but the published documents do not describe any limitation on its bottom height, nor do they describe any specific technical solutions for it to bear pressure in conjunction with the aluminum foil film 3. In this technical solution, the bottom height of the split top cap 103 is set to be the same as the top height of the aluminum foil film 3. This ensures that the aluminum foil film 3 can maintain a nearly flat state when under pressure, and the pressure can be distributed to the sealing cap body 100. The two share the pressure, preventing large deformation and damage / leakage.

[0030] Moreover, the top cover 103 and the sealing cover body 100 are concentric, and the pressure at the center of the aluminum foil film 3 is the greatest. Therefore, after the bottom surface of the top cover 103 and the top surface of the aluminum foil film 3 are at the same height, the pressure of the aluminum foil film 3 can be effectively dispersed, further improving the pressure-bearing effect.

[0031] Example 3 The purpose of this embodiment is to provide a specific pressure-bearing structure.

[0032] refer to Figure 1 and Figure 5The pressure-bearing structure 200 comprises at least one pressure-bearing ring, which is preferably concentrically aligned with the sealing cap body 100. Multiple pressure-bearing rings can be provided, and their width, spacing, and other values ​​can be modified according to actual needs. The technical effect of this structure is to maximize or optimize the support area or position on the surface of the aluminum foil film 3 within its limited surface area, thereby enabling it to withstand greater pressure on the limited surface area of ​​the aluminum foil film 3.

[0033] As a further improvement of this utility model, the plurality of pressure-bearing rings are evenly distributed in all directions around the center of the sealing cover body 100. This structure can be a petal-like distribution, with the plurality of pressure-bearing rings distributed around the center of the sealing cover body 100. The specific number and position can be modified according to actual needs.

[0034] Example 4 The purpose of this embodiment is to provide a pressure-bearing structure with an alternative specific structure.

[0035] refer to Figure 3 , Figure 4 and Figure 6 The pressure-bearing structure consists of several ribs, which are evenly distributed outwards from the center of the sealing cover body 100. The arrangement direction, position, number, spacing, and other parameters of the ribs can also be modified as needed.

[0036] Example 5 The purpose of this embodiment is to provide another specific pressure-bearing structure.

[0037] refer to Figure 7 The pressure-bearing structure consists of several pressure-bearing columns, which are evenly distributed outwards from the center of the sealing cover body 100. The position, number, spacing, and other parameters of their arrangement can also be modified as needed.

[0038] Working principle: By adding a pressure-bearing structure to the existing sealing cap body 100, the bottom surface of which is at the same height as the top surface of the aluminum foil film 3, the deformability of the aluminum foil sealing film 3 is reduced. Alternatively, the bottom surface of the broken top cap 103 can also be set to be at the same height as the top surface of the aluminum foil film 3, providing better support for the aluminum foil film 3 from the center, further ensuring that it does not undergo significant deformation. When the bucket is placed horizontally, the pressure is distributed to the sealing cap body 100, improving its pressure-bearing capacity. By utilizing the sealing cap body 100 and the aluminum foil film 3 to jointly bear pressure, the goal of achieving the highest pressure-bearing effect with the least amount of material is achieved.

[0039] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
