Description

Technical Field

[0001] The invention belongs to the technical field of food packaging, and in particular relates to a storage cup with a splash-proof sealed cup rim. Background Art

[0002] In daily life, storage cups packaged with sealing film are quite common, such as for beverages or food. However, to keep the beverages or food fresh, they are usually filled with nitrogen when sealing the package. By "replacing active gas with inert gas", the food spoilage is delayed from the chemical (anti-oxidation) and biological (antibacterial) levels, and the product form is protected by physical support, ultimately achieving the purpose of extending the shelf life and maintaining quality. Therefore, there will be a certain amount of pressure in the cup. In plateau areas, the greater the pressure, the more likely it is that the following technical defects will occur during the eating process:

[0003] 1) Once the cup contains a liquid beverage (such as yogurt), the internal pressure will leak out instantly when the sealing film is torn off, causing the liquid to splash out. This will not only cause inconvenience to consumers, but also stain clothes and tabletops, resulting in a poor user experience;

[0004] 2) The cup edge is fully bonded to the sealing film, resulting in a large sealing contact area and a serious lack of ease of opening the sealing film (for example, jelly). That is, there is a contradiction between sealing and ease of opening. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an improved storage cup with a splash-proof sealed cup rim.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A storage cup with a splash-proof sealed rim comprises a cup body and a rim, wherein the rim is formed with a plurality of annular sealing modules inwardly from the outer edge, an annular groove with an open top is formed between two adjacent annular sealing modules, and the annular groove and the inner edge of the rim are connected by a through opening penetrating the corresponding annular sealing modules; the top surfaces of the plurality of annular sealing modules are flush to form a sealing surface.

[0008] Preferably, the annular sealing module is arranged concentrically with the annular groove. This design can achieve relatively uniform sealing and can also be arranged at any position of the end portion opened by the edge.

[0009] According to a specific embodiment and preferred aspect of the present invention, there are at least two annular grooves. The liquid storage space formed by the multiple annular grooves can not only quickly disperse the pressure released during the peeling process, but also temporarily store the beverage released due to the pressure in the liquid storage space, eliminating the possibility of beverage splashing and preventing beverage waste.

[0010] In some specific embodiments, the multiple annular sealing modules are divided into an outer sealing portion and an inner sealing portion based on the outermost annular groove. The outer sealing portion is used to seal the cup rim against the sealing film, while the inner sealing portion is used to guide the gas inside the cup toward the annular groove and relieve pressure. The layout and application of the inner and outer sealing portions not only meet sealing requirements, but also improve the ease of removing the sealing film by reducing the contact area and segmenting it. Furthermore, when the sealing film is not fully removed, the annular groove can be used to guide and relieve pressure to release the gas inside the cup.

[0011] Preferably, the outer sealing portion is formed by an annular sealing module, and the width is at least 1 / 2 of the width of the cup rim, so as to meet the sealing requirements.

[0012] Furthermore, the inner sealing portion is composed of at least two annular sealing modules, and the sum of the widths of the multiple annular sealing modules of the inner sealing portion is less than or equal to 1 / 3 of the width of the outer sealing portion. Based on the width formed by the inner and outer sealing, the conflict between sealing and tearability is resolved.

[0013] According to another specific implementation and preferred aspect of the present invention, the widths of the multiple annular sealing modules of the inner sealing portion gradually increase from the inside to the outside. Based on the principle of gradually increasing the width of the annular sealing modules, a feeling of increasing ease in opening the lid is achieved.

[0014] According to another specific embodiment and preferred aspect of the present invention, the width of the plurality of annular grooves gradually increases from the inside to the outside. The resulting liquid storage space is variable, which means that instantaneous partial pressure and splashing of liquid can be achieved, further reducing the probability of splashing.

[0015] According to another specific embodiment and preferred aspect of the present invention, a through-hole is located on the annular sealing module of the inner sealing portion, and the through-hole is recessed inward from the top surface of the corresponding annular sealing module. Due to the layout of the through-hole, the contact area of ​​the entire annular sealing module is segmented, thereby improving the pressure relief capacity and the tearability of the sealing film.

[0016] Preferably, there are multiple through-holes and they are circumferentially spaced and distributed around the corresponding annular sealing module.

[0017] Furthermore, the through openings on the annular sealing module of the inner sealing portion are relatively staggered and distributed in an annular array. Based on the staggered layout, the beverage leakage rate is reduced, and the instantaneous pressure distribution capability is also increased.

[0018] In some specific embodiments, the widths of the through-ports on the same annular sealing module are equal. Specifically, the width of the through-ports on the same annular sealing module is greater than or equal to the width of the connected annular groove, and the widths of the through-ports on each annular sealing module gradually increase from the inside out. Here, by correlating the widths of the through-ports with the widths of the annular grooves and varying them with the groove widths, both pressure-dividing and flow-discharging capabilities can be combined to meet operational needs.

[0019] Due to the implementation of the above technical solution, the present invention has the following advantages compared with the prior art:

[0020] In the existing storage cup, when the sealing film is used for sealing, once there is a liquid drink in the cup (such as yogurt), the internal pressure will leak out instantly when the sealing film is torn off, causing the liquid to splash out, which not only brings inconvenience to consumers, but also stains clothes and tabletops, resulting in a poor user experience; at the same time, the cup edge is fully bonded and sealed with the sealing film, resulting in a large sealing contact area and causing serious inadequacy in the ease of peeling the sealing film (for example, jelly). The present invention has an overall design for the structure of the storage cup, which cleverly solves the shortcomings and defects of the existing technology. After using the storage cup, based on the sealing film sealingly attached to multiple annular sealing The annular groove is on the sealing surface of the mouth module and is connected to the cup body space. When the sealing film is gradually opened, the annular groove is used for instant pressure relief to balance the pressure difference between the inside and outside of the cup body, and the liquid flowing with the pressure relief is temporarily stored in the annular groove. Therefore, on the one hand, the present invention can instantly relieve pressure and divide the pressure to balance the pressure difference, and at the same time greatly reduce the splashing rate of the beverage when the film is removed based on the temporary storage of liquid, that is, it not only reduces the accident rate caused by removing the film, but also improves the user's physical experience; on the other hand, it solves the contradiction between sealing and easy removal, so that the sealing and easy removal between the sealing film and the edge of the cup can meet the use requirements, and at the same time, the structure is simple and the implementation is convenient.

[0034] like Figures 1 to 5 As shown, the storage cup with a splash-proof sealed rim of this embodiment includes a rim 1 and a cup body 2, wherein the top surface of the rim 1 is flush, and the sealing film is sealed on the top surface of the rim 1 to seal the storage cup.

[0035] Specifically, a plurality of concentrically arranged annular sealing modules 10 are formed from the outer edge inward of the cup rim 1, and an annular groove 11 with an open top is formed between each two adjacent annular sealing modules 10, wherein the annular groove 11 and the inner edge of the cup rim 1 are connected by a through opening 10a that passes through the corresponding annular sealing module 10.

[0036] In this example, there are three (or more) annular sealing modules 10, which are arranged in a spaced-apart arrangement from the inside out. Two annular grooves 11 are formed, and based on the outer annular groove 11, the three annular sealing modules 10 are divided into an outer sealing portion 1a and an inner sealing portion 1b. The outer sealing portion 1a is used for sealing the cup rim 1 with the sealing film, and the outer sealing portion 10 is composed of one annular sealing module a. At the same time, the width of the outer sealing portion 1a is at least 1 / 2 of the width of the cup rim 1; the inner sealing portion 1b is used to guide and relieve the gas in the cup body 2 to the annular groove 11, and the inner sealing portion 1b is composed of two annular sealing modules 10, and the sum of the widths of the two annular sealing modules 10 of the inner sealing portion 1b is less than or equal to 1 / 3 of the width of the outer sealing portion 1a. The through-holes 10a are located on the two annular sealing modules 10 of the inner sealing portion 1b, and there are multiple through-holes 10a and they are evenly spaced around the corresponding annular sealing modules 10.

[0037] Furthermore, the top surfaces of the three annular sealing modules 10 are flush to form a sealing surface, and the width of the two annular sealing modules 10 of the inner sealing part 1b gradually increases from the inside to the outside. Based on the principle that the width of the annular sealing modules gradually increases, a physical feeling of becoming easier and easier to open is achieved; the width of the annular groove 11 gradually increases from the inside to the outside, and the liquid storage space formed is variable, that is, it can achieve instantaneous pressure division and splashing liquid, further reducing the probability of splashing; the through-hole 10a is located on the annular sealing module 10 of the inner sealing part 1b, and the through-hole 10a is recessed inward from the top surface of the corresponding annular sealing module 10. The through-holes 10a on the annular sealing module 10 of the inner sealing part 1b are relatively staggered and distributed in an annular array. Based on the staggered layout, the beverage leakage rate is reduced, and the instantaneous pressure division capability is also increased.

[0038] In this example, the widths of the through-ports 10a on the same annular sealing module 10 remain uniform, and are greater than or equal to the width of the connected annular groove 11. The widths of the through-ports 10a on each annular sealing module 10 gradually increase from the inside outward. By correlating the widths of the through-ports 10a with the widths of the annular groove 11 and varying them with the groove width, the pressure-dividing and flow-discharging capabilities can be combined to meet operational requirements.

[0039] For a clearer presentation, in this example, the inner sealing portion 1b comprises two annular sealing modules 10, defined as a first annular sealing module and a second annular sealing module arranged from the inner line outward. The width of the first annular sealing module ranges from 0.1mm to 0.6mm. Within this range, the structure can meet both sealing and tearability requirements while also taking into account the feasibility of molding. A width less than 0.1mm may result in insufficient structural strength or inability to achieve the intended function; a width exceeding 0.6mm may increase material costs. The width of the second annular sealing module ranges from 0.18mm to 0.58mm. Within this range, the structure can meet both sealing and tearability requirements while also taking into account the feasibility of molding. A width less than 0.18mm may result in insufficient structural strength or inability to achieve the intended function; a width exceeding 0.58mm may increase material costs. A first through-notch is formed in the first annular sealing module, with a width ranging from 0.24mm to 0.84mm. A second through-notch is formed in the second annular sealing module, with a width ranging from 0.27mm to 1.37mm. The widths of the first and second through-notches are primarily determined to ensure that liquid or gas can enter the liquid storage tank. Within this width range, the structure can effectively function, ensuring a reasonable structural gap with other components and avoiding difficulties in liquid or gas discharge or functional failure caused by insufficient or excessive width. Simultaneously, the first and second annular grooves are arranged from the inside out, considering not only the groove width but also the groove depth. Generally, the groove depth ranges from 0.25mm to 0.85mm. The height dimension is set to meet the vertical space requirements of the structure and the requirement that the heat-sealed film cup rim 1 remain intact. Within this height range, the structure can achieve good performance, such as liquid storage. If the height is lower than 0.25mm, the temperature may be too high during film sealing, causing the cup edge 1 to deform and unable to meet the functions of liquid storage or exhaust; if the height is higher than 0.85mm, it may increase the structural cost, reduce the strength of the cup edge 1, and cause the product to break (in this case, the groove depth of the second annular groove is greater than the groove depth of the first annular groove). The groove width range of the first annular groove is 0.13mm to 0.73mm, and the groove width range of the second annular groove is 0.15mm to 1.15mm. The determination of the groove width mainly considers the ability of liquid or gas to enter the liquid storage tank and to buffer the air pressure difference in the cup to a certain extent. The structural size range of this application is not absolutely fixed and can be appropriately adjusted according to actual application requirements and special circumstances. At the same time, the protection scope of this application includes not only the specific size ranges clearly listed above, but also covers all similar size structures within this size range through equivalent replacement, reasonable scaling, or based on the same design principles and functions. Any structure within this size range, regardless of its specific size value, should be deemed to fall within the scope of protection of this patent as long as it adopts the same or equivalent structural design and functional implementation method as the application.

[0040] In summary, after adopting the storage cup, based on the sealing film being sealed and attached to the sealing surfaces of multiple annular sealing modules, and the annular groove and the cup body space being connected, when the sealing film is gradually peeled off, the annular groove is instantly depressurized to balance the pressure difference between the inside and outside of the cup body, and the liquid flowing with the pressure relief is temporarily stored in the annular groove. Therefore, on the one hand, the present invention can instantly relieve pressure and divide pressure to balance the pressure difference, and at the same time greatly reduce the splashing rate of beverages when peeling off the film based on the temporary storage of liquid, that is, it not only reduces the accident rate caused by peeling off the film, but also improves the user's physical experience; on the other hand, it solves the contradiction between sealing and easy peeling, so that the sealing and easy peeling between the sealing film and the cup edge are improved. The ease of peeling can meet the use requirements, and the structure is simple and easy to implement; fourthly, the annular sealing module and the annular groove are arranged concentrically, so that the design can seal relatively evenly and can also be arranged at any position of the edge peeling end; fifthly, the liquid storage space formed by multiple annular grooves can not only quickly disperse the leakage pressure in the peeling film, but also temporarily store the beverage leaked with the pressure in the liquid storage space, eliminating the probability of beverage splashing, and at the same time will not cause beverage waste; sixthly, based on the layout and application of the inner and outer sealing parts, while meeting the sealing requirements, based on the reduction and segmentation of the contact area, there is no It not only improves the ease of peeling off the sealing film, but also can discharge the pressure based on the annular groove diversion and pressure relief when the sealing film is not completely peeled off; the seventh aspect is that the outer sealing part is composed of an annular sealing module, and the width is at least 1 / 2 of the cup edge width, which meets the sealing requirements required for sealing, and the inner sealing part is composed of at least two annular sealing modules, and the sum of the widths of the multiple annular sealing modules of the inner sealing part is less than or equal to 1 / 3 of the width of the outer sealing part. Based on the width formed by the inner and outer seals, the contradiction between sealing and tearability is resolved; the eighth aspect is that the widths of the multiple annular sealing modules of the inner sealing part gradually increase from the inside to the outside, based on the annular The principle of gradually increasing the width of the annular sealing module is adopted to achieve a feeling of becoming easier and easier to open; the width of the multiple annular grooves gradually increases from the inside to the outside, and the liquid storage space formed is variable, that is to say, it can achieve instantaneous pressure division and splashing liquid, further reducing the probability of splashing; the through-holes on the annular sealing module of the inner sealing part are relatively staggered and distributed in a circular array. Based on the staggered layout, the leakage rate of the beverage is reduced, and the instantaneous pressure division capacity is also increased. Moreover, based on the correlation between the width of the through-holes and the width of the annular grooves, and changing with the change of the groove width, the pressure division capacity and the discharge capacity can be combined to meet the needs of use.

[0041] The above detailed description of the present invention is intended to enable persons familiar with the art to understand the contents of the present invention and implement them. It does not limit the scope of protection of the present invention. Any equivalent changes or modifications made based on the spirit of the present invention should be included in the scope of protection of the present invention.
