Description

Technical Field

[0001] This utility model relates to the field of food packaging technology, and in particular to a bowl lid and a bowl with graphic information. Background Technology

[0002] In the current market for fast food and convenience foods, bowl lids with promotional information such as QR codes for prize draws are widely used. Currently, the QR code is typically printed directly on the inner surface of the lid. Consumers can see the QR code after opening the lid and scan it to participate in the prize draw. However, because the promotional QR code is printed during the manufacturing stage of the bowl lid, before it is heat-sealed to the bowl body, the inner surface of the lid is directly visible during subsequent warehousing, transportation, and automated packaging. This allows criminals to steal the QR code information in bulk and use it for fraudulent activities. This risk of information leakage not only causes significant economic losses to businesses and undermines the fairness of promotional activities but also seriously harms consumer rights and damages brand reputation.

[0003] Therefore, how to design a new type of bowl lid that can prevent the illegal theft of promotional information before sealing, while ensuring its basic sealing function, has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0004] The main purpose of this utility model is to provide a bowl lid and a bowl with graphic information to solve the above-mentioned technical problems.

[0005] The objective of this utility model can be achieved by adopting the following technical solution:

[0006] A bowl lid includes: an upper lid assembly and a lower lid assembly stacked on top of each other, with an adhesive layer between the upper lid assembly and the lower lid assembly; a first tangent line is provided on the surface of the upper lid assembly, dividing the upper lid assembly into a connected upper lid body and a pull tab structure; a release layer is provided in a predetermined area between the pull tab structure and the adhesive layer, and a through hole is provided on the release layer along the thickness direction; a first graphic layer is provided on the bottom side of the pull tab structure corresponding to the predetermined area.

[0007] The tongue structure includes a main body and a first tongue piece disposed on the main body; the main body covers the preset area, and the first tongue piece protrudes from the outer contour of the upper cover body.

[0008] The lower cover assembly has a second tangent line on its surface, which divides the lower cover assembly into a lower cover body and a peelable part. The position of the peelable part corresponds vertically to the position of the through hole, so that the peelable part can be bonded to the body part through the adhesive layer. The connection strength between the peelable part and the lower cover body is less than the bonding strength between the peelable part and the body part.

[0009] The lower cover body includes a lower main body part and a pinch handle part connected to each other; a third tangent line is provided between the pinch handle part and the lower main body part, and the two ends of the third tangent line extend to the edge of the lower main body part respectively; the pinch handle part is bonded to the first tongue piece.

[0010] The plurality of through holes are provided, and the plurality of through holes are arranged on the release layer to form a through hole band extending along the boundary of the preset area, and the through hole band is provided around the first graphic layer.

[0011] The through-hole strip has an outer boundary and an inner boundary, and the shortest straight-line distance between the outer boundary and the inner boundary is 2mm to 10mm.

[0012] The minimum straight-line distance between the outer edge of the first graphic layer and the inner boundary of the through-hole strip is not less than 2 mm.

[0013] The upper cover assembly comprises, from top to bottom, a protective layer, a second graphic layer, a printed film layer, and the first graphic layer; the lower cover assembly comprises, from top to bottom, a barrier layer and a heat-sealing layer.

[0014] The bowl lid has two tongues extending radially outward, the two tongues including a first tongue and a second tongue disposed opposite to the first tongue.

[0015] A bowl with graphic information includes a bowl body, the bowl body having a cavity and an opening communicating with the cavity, and the opening of the bowl body being provided with a bowl lid as described above.

[0016] The beneficial technical effects of this utility model are as follows:

[0017] This invention achieves complete concealment of promotional information by placing the first graphic layer on the bottom side of the pull tab structure and physically shielding it with the lower cover assembly. This fundamentally solves the problem in the prior art where sensitive information such as QR codes is visible in the finished product stage of the bowl lid. Simultaneously, the combination of the release layer and the through-hole design forms a controlled local bonding mechanism, preventing accidental opening of the pull tab structure while ensuring that legitimate users can obtain the hidden information through active tearing. Any unauthorized information acquisition must damage the bowl lid structure and leave irreversible marks. This "physical isolation + active disclosure + single-use" technical solution effectively eliminates the possibility of bulk theft of QR code information during warehousing, transportation, and packaging, protecting the fairness of promotional activities and the economic interests of merchants, while maintaining the basic sealing function of the bowl lid and a good user experience.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0030] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0031] like Figures 1-5As shown in the figure, an embodiment of the present invention provides a bowl lid, comprising: an upper lid assembly and a lower lid assembly stacked on top of each other, with an adhesive layer 30 disposed between the upper lid assembly and the lower lid assembly; a first tangent line 13 is disposed on the surface of the upper lid assembly, the first tangent line 13 dividing the upper lid assembly into a connected upper lid body 11 and a pull tab structure 12; a release layer 14 is disposed in a preset area between the pull tab structure 12 and the adhesive layer 30, and a through hole 41 is disposed on the release layer 14 along the thickness direction; a first graphic layer 17 is disposed on the bottom side of the pull tab structure 12 corresponding to the preset area.

[0032] In this embodiment, the bowl lid 80 includes an upper lid assembly and a lower lid assembly in its overall structure. The upper lid assembly and the lower lid assembly are arranged in a stacked manner to form the main body of the bowl lid 80. In order to combine the upper lid assembly and the lower lid assembly into a whole, an adhesive layer 30 is provided between them. The function of the adhesive layer 30 is to bond the bottom surface of the upper lid assembly and the top surface of the lower lid assembly together to form a stable composite structure.

[0033] To enable partial revealing functionality, a first tangent line 13 is provided on the surface of the cover assembly (i.e., the side facing outwards and away from the rim). This first tangent line 13 is a pre-formed indentation or semi-cut line created through processes such as die-cutting. It extends along a predetermined path, thereby physically dividing the cover assembly into two parts: the larger cover body 11 and the smaller pull tab structure 12. It is worth noting that the first tangent line 13 does not completely sever the cover, but rather maintains a necessary connection between the cover body 11 and the pull tab structure 12, ensuring that the pull tab structure 12 will not detach when no external force is applied. However, when the user applies a pulling force, it can be easily torn open along the first tangent line 13.

[0034] A release layer 14 is specifically provided in a predetermined area between the tab structure 12 and the adhesive layer 30. This predetermined area roughly corresponds to the outline of the main body 121 of the tab structure 12 in a top view. The function of the release layer 14 is to prevent the upper cover assembly (i.e., the tab structure) within its coverage area from bonding with the adhesive layer 30. In this way, when the user pulls up the tab structure 12, this area will not generate strong resistance due to adhesion.

[0035] To ensure both easy peeling and sufficient adhesion between the pull tab structure 12 and the underlying structure before opening, preventing accidental opening, through-holes 41 are provided along the thickness direction of the release layer 14. These through-holes 41 penetrate the entire release layer 14, providing a "channel" for the adhesive layer 30. Through these through-holes 41, the material of the adhesive layer 30 can pass through the release layer 14, directly contacting and bonding with the bottom surface of the pull tab structure 12. This design creates a localized bond between the pull tab structure 12 and the underlying adhesive layer 30, rather than a large area of ​​complete non-adhesion, thus balancing the need for easy peeling and prevention of accidental opening.

[0036] Furthermore, to conceal information, a first graphic layer 17 is provided on the bottom side of the pull tab structure 12 (i.e., the side facing the adhesive layer 30) at a position corresponding to the aforementioned preset area. Specific patterns, text, or symbols can be printed on this first graphic layer 17. Since this first graphic layer 17 is located inside the pull tab structure 12 and is obscured by the lower cover assembly, it is invisible under normal conditions. Only when the user tears open and lifts the pull tab structure 12 along the first tangent line 13 will the information carried by the first graphic layer 17 be revealed, thus achieving the effect of information concealment and a progressive interactive experience.

[0037] This embodiment achieves physical concealment and protection of graphic and textual information through the above structural design. The first graphic and textual layer 17 is completely covered after the bowl lid 80 is sealed, avoiding the risk of premature information leakage. Users need to actively peel off the layer to obtain the graphic and textual information on the first graphic and textual layer 17, thereby ensuring information security. This is particularly suitable for bowl lids 80 containing sensitive promotional information such as QR codes and barcodes.

[0038] In one embodiment, the tongue structure 12 includes a main body portion 121 and a first tongue piece 122 disposed on the main body portion 121; the main body portion 121 covers the preset area, and the first tongue piece 122 protrudes from the outer contour of the upper cover body 11.

[0039] In this embodiment, in order to enable the user to easily pull the tongue structure 12 to reveal the first graphic layer 17 below it, the tongue structure 12 includes a main body 121 and a first tongue piece 122 disposed on the main body 121.

[0040] Specifically, the main body portion 121 is the main area of ​​the pull tab structure 12, and its shape and size in top view correspond to the preset area, that is, the main body portion 121 covers the preset area. Therefore, the release layer 14 and through-hole 41 used to achieve controllable adhesion, as well as the hidden first graphic layer 17, are all located below the main body portion 121. This design ensures that the first graphic layer 17 is completely hidden when the main body portion 121 is not peeled off, avoiding accidental exposure of information.

[0041] The first tongue 122 is designed for easy gripping and lifting by the user. It is attached to the edge of the main body 121 and extends outward from that edge. From the overall outline of the lid 80, the first tongue 122 protrudes beyond the outer contour of the main body 11. This design allows the user to easily see and pinch this protruding part when the lid 80 is sealed to the bowl. It provides the user with an intuitive and convenient point of application; the user simply pinches the first tongue 122 and lifts it upward to begin peeling the entire pull tab structure 12 along the first tangent line 13. During the peeling process, the release layer 14 and the through-hole 41 within the preset area covered by the main body 121 function. The localized adhesion at the through-hole 41 provides moderate resistance to the peeling operation, ensuring the user can feel the tearing process and preventing accidental opening; while the other areas covered by the release layer 14 remain relatively easy to peel, making the entire tearing process both challenging and not overly difficult.

[0042] In one embodiment, the surface of the lower cover assembly is provided with a second tangent 22, which divides the lower cover assembly into a lower cover body 21 and a peelable portion 23; the position of the peelable portion 23 corresponds vertically to the position of the through hole 41, so that the peelable portion 23 can be bonded to the body portion 121 through the adhesive layer 30; wherein, the connection strength between the peelable portion 23 and the lower cover body 21 is less than the adhesive strength between the peelable portion 23 and the body portion 121.

[0043] In this embodiment, not only does the upper cover assembly have a pre-set tear-off structure, but the lower cover assembly also has a corresponding separable structure to achieve simultaneous peeling. Specifically, a second tangent line 22 is pre-set on the surface of the lower cover assembly (i.e., the side facing the upper cover assembly). This second tangent line 22 can also be formed by processes such as die-cutting, and its function is to divide the lower cover assembly into two parts: a larger lower cover body 21 and a smaller peelable part 23. The second tangent line 22 constitutes a weak connection between the peelable part 23 and the lower cover body 21.

[0044] The peelable portion 23 on the lower cover assembly is positioned, shaped, and sized vertically corresponding to the through-hole 41 on the release layer 14. Due to the presence of the through-hole 41, the adhesive layer 30 can pass through the release layer 14 to firmly bond the bottom surface of the main body portion 121 of the pull tab structure 12 to the top surface of the peelable portion 23.

[0045] The connection strength between the peelable part 23 and the lower cover body 21 is determined by factors such as the depth of the second tangent 22 and the density of breakpoints, and is designed to be relatively weak. The bonding strength between the peelable part 23 and the main body 121 of the pull tab structure 12 is determined by the material properties of the adhesive layer 30 and the bonding area / number of bonding points formed through the through hole 41, and is designed to be relatively strong.

[0046] Based on the aforementioned strength difference, when the user pulls the tab structure 12, the adhesive force between the main body 121 of the tab structure 12 and the peelable part 23 is much greater than the connection force between the peelable part 23 and the lower cover body 21. Therefore, the applied pulling force will not cause the tab structure 12 to detach from the peelable part 23, but will preferentially act on the weaker second tangent line 22, causing the peelable part 23 to be completely torn off from the lower cover body 21 along the second tangent line 22 and lifted up together with the tab structure 12.

[0047] Removing the peelable part 23 creates a hole that extends through the thickness of the lower cover body 21. In applications such as instant noodle bowls where broth needs to be drained, this hole can function as a drainage hole, allowing consumers to drain the broth from the bowl before eating.

[0048] In one embodiment, the lower cover body 21 includes a lower body portion 211 and a grip portion 212 connected to each other; a third tangent line 213 is provided between the grip portion 212 and the lower body portion 211, and the two ends of the third tangent line 213 extend to the edge of the lower body portion 211 respectively; the grip portion 212 is bonded to the first tongue piece 122.

[0049] In this embodiment, the lower cover body 21 includes two connected parts: a lower body part 211 and a handle part 212. The lower body part 211 constitutes the main area of ​​the lower cover body 21, and its main functions are to form a sealed connection with the bowl body 70 and to form a peripheral support structure for drainage holes after the peelable part 23 is removed.

[0050] The gripper portion 212 is a protruding part specifically designed for easy user gripping. It remains connected to the lower main body portion 211, but a third tangent line 213 is provided between them. This third tangent line 213 functions similarly to the first tangent line 13 and the second tangent line 22 described above, forming a controllable tear line between the gripper portion 212 and the lower main body portion 211 through pre-cutting or indentation. To ensure the integrity of the tear, both ends of the third tangent line 213 extend to the edge of the lower main body portion 211, forming a complete separation path.

[0051] In the assembly structure of this embodiment, the gripper 212 is positioned vertically opposite to the first tongue 122 of the upper cover assembly, and the two are bonded together by the adhesive layer 30. This design allows the user to simultaneously grip both the first tongue 122 and the gripper 212, forming a composite grip structure, which improves the convenience and reliability of operation.

[0052] When the user pulls the tab, due to the adhesion between the first tab 122 and the gripper 212, the pulling force acts simultaneously on the tab structure 12 of the upper cover assembly and the gripper 212 of the lower cover assembly. Under continuous pulling force, the tangents tear in a predetermined order of strength: first, tearing begins at the third tangent 213, at which point the tab structure 12 and the gripper 212 attached below it begin to peel off from the upper cover body 11 as a whole; then, the tearing at the first tangent 13 continues, causing the main body 121 of the tab structure 12 to gradually detach from the predetermined area below it; finally, during the tearing process of the tab structure 12, because the adhesive strength between the main body 121 of the tab structure 12 and the peelable part 23 is greater than the connection strength between the peelable part 23 and the lower cover body 21, the peelable part 23 on the lower cover body 21 is gradually pulled and torn off from the lower main body 211, ultimately forming a drainage hole penetrating its thickness on the surface of the lower cover body 21.

[0053] This multi-layered tearing design not only ensures the gradual reveal of hidden graphic information but also provides users with clear operational feedback, making the entire peeling process more controllable. It also provides a practical soup draining function for applications such as instant noodle bowls.

[0054] In one specific embodiment, the first tangent 13 and the third tangent 213 are connected end to end, forming a continuous tear path. Specifically, the first tangent 13 is disposed on the surface of the upper cover assembly to divide the upper cover body 11 and the pull tab structure 12; the third tangent 213 is disposed between the lower body portion 211 and the handle portion 212 of the lower cover assembly. In the layered structure of the bowl lid 80, the two endpoints of the first tangent 13 coincide or nearly coincide with the corresponding endpoints of the third tangent 213 in the vertical projection direction, thereby forming a continuous tear guide line on the entire bowl lid 80.

[0055] This end-to-end design ensures that when the user begins to pull up the first tongue 122, the tear starts from the connection point and proceeds sequentially along the third tangent 213 and the first tangent 13, guaranteeing the continuity and controllability of the tearing process. Due to the connection of the two tangents, the tearing force can be smoothly transferred from the third tangent 213 of the lower cover assembly to the first tangent 13 of the upper cover assembly.

[0056] In one embodiment, a plurality of through holes 41 are provided, and the plurality of through holes 41 are arranged on the release layer 14 to form a through hole band 40 extending along the boundary of the preset area, and the through hole band 40 is provided around the first graphic layer 17.

[0057] In this embodiment, in order to ensure that the pull tab structure 12 has appropriate peel resistance while protecting the first graphic layer 17 from damage, the through holes 41 on the release layer 14 are not randomly distributed, but are provided with multiple through holes 41, which are arranged on the release layer 14 according to a specific path.

[0058] Specifically, the plurality of through holes 41 are arranged on the release layer 14 to form a through hole band 40 extending along the boundary of the preset region. The through hole band 40 is arranged to follow the outer contour of the preset region, forming a ring or near-ring distribution pattern around the region. Through this arrangement, the adhesive layer 30 can form local bonding points with the pull tab structure 12 along the boundary through the various through holes 41 in the through hole band 40, thereby establishing a controllable connection strength in the peripheral area of ​​the pull tab structure 12.

[0059] More importantly, the through-hole strip 40 is disposed around the first graphic layer 17. This means that the first graphic layer 17 is located in the central area enclosed by the through-hole strip 40, while the through-hole strip 40 itself is located on the periphery of the first graphic layer 17. Since there are no through holes 41 in the area of ​​the first graphic layer 17, the adhesive layer 30 below this area cannot be directly bonded to the pull tab structure 12. Therefore, during the peeling process, the first graphic layer 17 will not tear or be damaged due to excessive adhesive force.

[0060] When the user pulls the tab structure 12, the tearing force mainly acts on the through-hole strip 40 area, that is, the outer area of ​​the first graphic layer 17. The individual through-holes 41 in the through-hole strip 40 provide moderate and dispersed adhesive resistance, allowing the user to feel clear operational feedback during the peeling process and preventing accidental opening too easily. Simultaneously, since the adhesive points are mainly distributed in the boundary area, the graphic content in the center of the first graphic layer 17 can remain intact during the peeling process, ensuring the integrity and readability of the information.

[0061] This through-hole design 40 also helps to achieve a uniform peeling effect. Because the adhesive points are evenly distributed along the boundary, the pull tab structure 12 will detach from each adhesive point sequentially during peeling, thereby ensuring a smooth peeling process and the integrity of the final torn portion.

[0062] In one embodiment, the through-hole strip 40 has an outer boundary and an inner boundary, and the shortest straight-line distance from the outer boundary to the inner boundary is 2 mm to 10 mm.

[0063] In this embodiment, the via strip 40 has clearly defined geometric boundaries, including an outer boundary and an inner boundary. The outer boundary is the boundary line of the via strip 40 away from the first graphic layer 17, and the inner boundary is the boundary line of the via strip 40 closer to the first graphic layer 17. The area between these two boundaries constitutes the effective range of the via strip 40, and multiple vias 41 are provided within this annular region.

[0064] In this embodiment, the shortest straight-line distance from the outer boundary to the inner boundary is controlled within the range of 2mm to 10mm. This size range is determined based on the following technical considerations:

[0065] When the width of the through-hole strip 40 is less than 2mm, the bonding area is too small to provide sufficient peeling resistance. When the width of the through-hole strip 40 exceeds 10mm, the bonding area is too large, making the peeling operation difficult. Users need to apply excessive force to complete the tearing action, which not only affects the user experience but may also damage the first graphic layer 17 or the pull tab structure 12 itself due to excessive force during the peeling process.

[0066] Within a range of 2mm to 10mm, the through-hole tape 40 provides moderate adhesive strength, ensuring a secure connection of the pull tab structure 12 when it is not in the open state, while also allowing the user to complete the peeling operation smoothly with reasonable force.

[0067] In one embodiment, the minimum straight-line distance between the outer edge of the first graphic layer 17 and the inner boundary of the through-hole strip 40 is not less than 2 mm.

[0068] In this embodiment, to prevent damage to the first graphic layer 17 during the peeling process, the spatial relationship between the outer edge of the first graphic layer 17 and the inner boundary of the via strip 40 is specifically defined. Specifically, the minimum straight-line distance between the two is not less than 2 mm.

[0069] The minimum distance of 2mm provides ample safety buffer space for the first graphic layer 17. During the peeling process, even if slight tearing, irregularities, or material deformation occur near the inner boundary of the through-hole strip 40, it will not affect the graphic content of the first graphic layer 17, ensuring the integrity of the information. Furthermore, this distance setting also helps improve the visual appeal of the first graphic layer 17. After the pull tab structure 12 is completely peeled off, a clear blank border area will appear around the first graphic layer 17, which not only makes the graphic content more prominent but also provides better visual conditions for subsequent scanning or recognition operations.

[0070] In one embodiment, the upper cover assembly includes, from top to bottom, a protective layer 19, a second graphic layer 18, a printed film layer 110, and a first graphic layer 17; the lower cover assembly includes, from top to bottom, a barrier layer 24 and a heat-sealing layer 25.

[0071] In this embodiment, the top cover assembly adopts a four-layer structure, which includes, from top to bottom (i.e., from the outer surface away from the bowl opening to the inner surface near the bowl opening): a protective layer 19, a second graphic layer 18, a printed film layer 110, and a first graphic layer 17.

[0072] The protective layer 19 is located on the outermost layer and its main function is to protect the internal graphic layer and printed film layer 110 from damage caused by the external environment, such as preventing scratches and moisture. The second graphic layer 18 is located below the protective layer 19 and can carry visible graphic information, such as brand logos and product information. The printed film layer 110 serves as an intermediate layer and provides a suitable substrate for graphic printing. The first graphic layer 17 is located on the innermost layer of the top cover assembly, namely the hidden graphic layer set on the bottom side of the pull tab structure 12, which carries graphic information that can only be revealed through a peeling operation.

[0073] The lower cover assembly has a two-layer structure, comprising, from top to bottom: a barrier layer 24 and a heat-sealing layer 25. It should be noted that the aforementioned adhesive layer 30 is actually a functional coating on the surface of the barrier layer 24.

[0074] Among them, the barrier layer 24 is located on the upper layer of the lower cover assembly, and its main function is to provide barrier performance against moisture, oxygen, etc., to prevent adverse substance exchange between the food in the bowl and the external environment; the heat sealing layer 25 is located on the bottom layer of the lower cover assembly and is in direct contact with the bowl body 70. Its material has good heat sealing performance and can form a firm seal connection with the rim of the bowl body 70 under heating conditions.

[0075] This multi-layered composite structure design not only ensures that the bowl lid 80 has excellent sealing and barrier performance, but also provides a structural foundation for carrying and displaying multiple graphic and textual information in layers.

[0076] In this embodiment, the user's information acquisition process is divided into two stages: In the first stage, the user can directly observe the content of the second graphic layer 18 through the protective layer 19, obtaining basic product information and visual appeal; in the second stage, the user needs to actively pinch the first tongue 122 and perform a tearing operation along the first tangent line 13 to gradually peel off the pull tab structure 12, ultimately discovering the first graphic layer 17 on the back of the pull tab structure 12. This transition from passive observation to active operation effectively creates an exploratory experience. The moderate peeling resistance provided by the through-hole strip 40 ensures that the user receives clear tactile feedback during the tearing process, enhancing the sense of ritual in the operation. When the hidden first graphic layer 17 is fully revealed, the user experiences a sense of discovery, significantly improving the participation and fun of the promotional activity.

[0077] In one embodiment, the protective layer 19 is made of PET material; the printed film layer 110 is a composite film of PET film and PP synthetic paper.

[0078] In this embodiment, the protective layer 19 is made of PET material. PET (polyethylene terephthalate) has excellent transparency, mechanical strength, and chemical corrosion resistance, providing reliable protection for the internal graphic layer while maintaining good light transmittance, ensuring that the graphic information of the second graphic layer 18 can be clearly observed by the user through the protective layer 19. The printed film layer 110 is a composite film of PET film and PP synthetic paper. This composite structure can fully utilize the advantages of both materials.

[0079] This material configuration not only ensures the overall performance of the bowl lid 80, but also provides a reliable material foundation for the high-quality presentation and long-term preservation of graphic information.

[0080] In one embodiment, the barrier layer 24 is a composite film of PET film and aluminum foil; the heat-sealing layer 25 is a PE heat-sealing film.

[0081] In this embodiment, the barrier layer 24 is a composite film of PET film and aluminum foil. This composite structure combines the excellent barrier properties of both materials. This composite film can effectively protect the quality of food inside the bowl, prevent the external environment from adversely affecting the food, and prevent the aroma and moisture of the food from escaping.

[0082] The heat-sealing layer 25 is made of PE heat-sealing film. PE (polyethylene) material has excellent heat-sealing performance and can form a strong heat-melt bond with the bowl body 70 material under appropriate temperature and pressure conditions. PE heat-sealing film has good flexibility and sealing performance, can adapt to changes in the shape of the bowl rim, and ensures the integrity and reliability of the seal; at the same time, PE material also has good food safety and meets the relevant standards for food contact materials.

[0083] By using a PET film and aluminum foil composite film as a barrier layer 24, and a PE heat-sealing film as a heat-sealing layer 25, the lower cover assembly can provide excellent barrier protection while achieving a reliable sealed connection with the bowl body 70, ensuring the sealing integrity and food safety of the entire packaging system.

[0084] In one embodiment, the first graphic layer 17 includes at least one of a QR code or a barcode.

[0085] In this embodiment, in order to achieve effective information transmission and user interaction, especially for application needs such as promotional activities, the first graphic layer 17 includes at least one of QR code or barcode.

[0086] When the first text and image layer 17 includes a QR code, this QR code can carry rich digital information, such as promotional activity links, lottery codes, product details, official website links, user feedback entry points, etc. Users can quickly obtain relevant information or participate in corresponding activities by scanning the QR code with smartphones or other devices. QR codes have a large information capacity and strong error correction capabilities; they can still be recognized normally even when partially damaged, making them suitable for carrying important promotional or product information.

[0087] When the first graphic layer 17 includes a barcode, the barcode can be used for purposes such as product identification.

[0088] In some application scenarios, the first image and text layer 17 can include both QR codes and barcodes to meet different functional requirements. For example, barcodes are used for basic product identification, while QR codes are used to carry promotional information. The two complement each other, providing users and merchants with more comprehensive information services.

[0089] Since the first graphic layer 17 is located on the bottom side of the pull tab structure 12, it is completely hidden when the lid 80 is sealed. It can only be revealed after the user actively peels it off. This design effectively prevents the premature leakage of QR code or barcode information in packaging, storage and transportation, and ensures the fairness and security of promotional activities. It is especially suitable for promotional scenarios that require preventing cheating, such as lucky draws and points redemption.

[0090] In one embodiment, the bowl lid 80 has two radially outwardly extending tongues, the two tongues including a first tongue 122 and a second tongue 60 disposed opposite to the first tongue 122.

[0091] In this embodiment, to facilitate user operation of the bowl lid 80 from different angles and positions, the bowl lid 80 has two radially outwardly extending tongues. The two tongues are arranged symmetrically on the bowl lid 80, that is, the two tongues include a first tongue 122 and a second tongue 60 disposed opposite to the first tongue 122.

[0092] The first tongue 122 is the tongue associated with the tongue-pulling structure 12 mentioned in the previous embodiment. Its main function is to provide a gripping point for the peeling operation. The user can peel off the tongue-pulling structure 12 and expose the first graphic layer 17 by lifting the first tongue 122.

[0093] After the lid 80 is sealed to the bowl body 70, both tongues protrude from the outer contour of the bowl body 70. In a specific application, the user can peel off the peelable part 23 by pinching the first tongue 122 to drain water, or pinch the second tongue 60 to peel the entire lid 80 off the bowl body 70.

[0094] like Figure 6 As shown, corresponding to the above-mentioned bowl lid, this utility model embodiment also provides a bowl with graphic information. The bowl includes a bowl body 70, the bowl body 70 has a cavity 71 and an opening communicating with the cavity 71, and the opening of the bowl body 70 is provided with a bowl lid 80 as described above.

[0095] In this embodiment, the bowl with graphic information mainly includes a bowl body 70 and a bowl lid 80 disposed on the bowl body 70. The bowl body 70 has a cavity 71 for holding food and an opening communicating with the cavity 71. The cavity 71 constitutes the main storage space of the bowl body 70.

[0096] The opening is the upward-opening portion of the cavity 71, and its edge is designed as a flat, annular structure to provide a suitable contact surface for the sealing of the lid 80. The diameter and shape of the opening match the corresponding dimensions of the lid 80 to ensure an effective fit and seal.

[0097] The key feature is that the rim of the bowl body 70 is provided with the bowl lid 80 described in the aforementioned embodiments. The bowl lid 80 possesses all the technical features described in the aforementioned embodiments, including the stacked structure of the upper and lower lid components, the pull tab structure 12 divided by the first tangent 13, the setting of the release layer 14 and the through hole 41, the hidden first graphic layer 17, and various material configurations, etc.

[0098] In practical applications, the bowl lid 80 forms a sealed connection with the opening of the bowl body 70 through its heat-sealing layer 25. Consumers can choose different opening methods when using it: if they only want to open the lid normally for eating, they can lift it from the second tongue 60 and tear the entire bowl lid 80 off the opening of the bowl; if they want to obtain hidden graphic information (such as a QR code), they need to follow the description of the aforementioned embodiment, pull the first tongue 122 to start the peeling operation, and gradually tear open the third tangent line 213, the first tangent line 13 and the second tangent line 22 to finally reveal the information content on the first graphic layer 17.

[0099] When the detachable part 23 is removed, a drainage hole will be formed on the bowl lid 80, which provides an additional practical function for foods such as instant noodles that require draining soup.

[0100] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
