Technical Field
[0001] This utility model relates to the field of food container technology, and in particular to a bowl lid and a bowl. Background Technology
[0002] With the widespread adoption of fast-paced lifestyles, the market demand for convenience foods such as instant noodles, instant rice noodles, and self-heating porridge continues to grow. The "bowl body + lid" combination in their packaging structure is a core component ensuring food storage safety and ease of consumption. However, existing technologies only meet the minimum requirement of "basic sealing" and still have shortcomings: ordinary lids must be completely torn open by hand, which is not only laborious but also makes the size and shape of the opening completely uncontrollable. In actual use, the opening is often too small or irregular, causing water flow obstruction when pouring hot water, leading to scalding from the edges. Therefore, a new lid structure is urgently needed to achieve easy opening and controllability. Utility Model Content
[0003] The main purpose of this utility model is to provide a bowl lid and a bowl to solve the above-mentioned technical problems.
[0004] In a first aspect, the present invention provides a bowl lid, the bowl lid comprising an upper cover assembly, an adhesive layer and a lower cover assembly arranged sequentially from top to bottom; on both sides of a preset opening of the bowl lid, a first die-cutting line is respectively provided on the upper cover assembly; a second die-cutting line is provided on the lower cover assembly along the outline of the preset opening, the second die-cutting line being located between the first die-cutting lines, and used to form the opening path of the preset opening together with the first die-cutting lines; The upper cover assembly has a pull tab, and the first die-cut line extends from both sides of the root of the pull tab on the surface of the upper cover assembly; the lower cover assembly has a pinch handle, and the root of the pinch handle is provided with a third die-cut line; the pull tab and the pinch handle are positioned opposite each other, and the two ends of the third die-cut line extend to both sides of the root of the pull tab.
[0005] A release layer is provided between the top cover assembly and the adhesive layer within a preset area; the orthographic projections of the first die-cutting line, the second die-cutting line, and the third die-cutting line along the thickness direction of the bowl cover all fall within the coating area of the release layer.
[0006] The lower cover assembly includes a retaining portion located between the second die-cutting line and the third die-cutting line. A fourth die-cutting line passes through the retaining portion to form a latch on the retaining portion. The latch is configured to accommodate the pull tab and the pinch handle after the bowl lid is opened along the opening path. The two ends of the fourth die-cutting line are respectively spaced from the first die-cutting line.
[0007] The orthographic projection of the fourth die-cutting line along the thickness direction of the bowl lid falls into the coating area of the release layer.
[0008] The upper cover assembly includes an upper cover body located outside the first die-cutting line and a first peelable portion located inside the first die-cutting line; one edge of the first peelable portion protrudes from the rim of the bowl to form the pull tab; the lower cover assembly includes a lower cover body corresponding to the upper cover body and a second peelable portion located inside the second die-cutting line; the lower cover body forms the retaining portion between the second die-cutting line and the third die-cutting line, and one edge of the lower cover body protrudes from the rim of the bowl to form the grip.
[0009] The minimum distance between the first die-cutting line and the nearest point of the release layer coating edge is d1, where d1 ≥ 2 mm.

[0011] The minimum distance between the third die-cutting line and the nearest point of the release layer coating edge is d3, where d3 ≥ 2 mm.
[0012] The first die-cutting line is symmetrically distributed along the center line of the bowl lid; the second die-cutting line has an arc or U-shaped profile.
[0013] Secondly, this utility model also provides a bowl, including a bowl body, the rim of which is covered with a bowl lid as described in the first aspect.
[0014] The beneficial technical effects of this utility model are as follows: This bowl lid, through the first die-cutting line on the upper lid assembly, the second and third die-cutting lines on the lower lid assembly, and the corresponding pull tab and pinch handle, forms a controllable opening path, allowing users to easily pinch and pull, achieving multi-layer simultaneous tearing, thereby forming a pre-set opening of a regular shape and appropriate size on the bowl lid. This design effectively solves the problems of existing bowl lids being difficult to tear by hand, and the uncontrollable opening causing water flow obstruction and hot water splashing leading to scalding, thus improving the convenience of opening and the safety of use.

[0022] Please also refer to Figures 1-6 This utility model embodiment provides a bowl lid 10, which is used to seal and cover the rim of a bowl 31 to seal and package convenient food (such as instant noodles, instant rice noodles, etc.) inside the bowl 31. The bowl lid 10 has a multi-layer composite structure, including an upper cover assembly 11, an adhesive layer 12, and a lower cover assembly 13 arranged sequentially from top to bottom. On both sides of the preset opening 16 of the bowl lid 10, the upper cover assembly 11 is provided with first die-cutting lines 14; the lower cover assembly 13 is provided with second die-cutting lines 15 along the contour of the preset opening 16; the second die-cutting lines 15 are located between the first die-cutting lines 14 and are used to form the opening path of the preset opening 16 together with the first die-cutting lines 14. The upper cover assembly 11 has a pull tab 17, and the first die-cut line 14 extends from both sides of the root of the pull tab 17 on the surface of the upper cover assembly 11; the lower cover assembly 13 has a pinch handle 18, and a third die-cut line 19 passes through the root of the pinch handle 18; the pull tab 17 and the pinch handle 18 are positioned opposite each other, and the two ends of the third die-cut line 19 extend to both sides of the root of the pull tab 17.
[0023] In this embodiment, the upper cover assembly 11, the adhesive layer 12, and the lower cover assembly 13 are stacked to form an integrated bowl lid structure. To facilitate the user in tearing open the bowl lid 10 to form a pre-set opening 16 for pouring water, a specific opening structure is designed on the bowl lid 10 in this embodiment.
[0024] On both sides of the preset opening 16 of the bowl lid 10, the upper cover assembly 11 is respectively provided with first die-cutting lines 14. Specifically, there are two first die-cutting lines 14, located on both sides of the preset opening 16. Each first die-cutting line 14 forms a pre-break line penetrating the upper cover assembly 11 through a die-cutting process. For example, a die-cutting tool cuts a tangent line with a depth reaching the thickness of the upper cover assembly 11 on its surface to achieve a controllable tearing path. The first die-cutting lines 14 can extend along the surface of the bowl lid 10 for a certain length, the specific length of which depends on the size of the bowl lid 10 and the size of the preset opening 16, and are used to guide the separation of the upper cover assembly 11 when it is opened.
[0025] A second die-cutting line 15 is provided on the lower cover assembly 13 along the contour of the preset opening 16. The second die-cutting line 15 is located between the first die-cutting lines 14 and is used to form the opening path of the preset opening 16 together with the first die-cutting lines 14. Specifically, the second die-cutting line 15 is formed on the lower cover assembly 13 through a die-cutting process, and its contour extends along the shape of the preset opening 16, matching the latter half of the path of the second die-cutting line 15, ensuring that the two can cooperate to open the preset opening 16 of a certain size. The position of the second die-cutting line 15 is set between the two first die-cutting lines 14, that is, the projection of the second die-cutting line 15 is located inside the two first die-cutting lines 14 and adjacent to each other, ensuring that during the opening process, the first die-cutting lines 14 and the second die-cutting line 15 work together to form a continuous opening path. For example, when a user applies force to the bowl lid 10, the upper lid assembly 11 tears along the first die-cut line 14 and the lower lid assembly 13 tears along the second die-cut line 15, thereby jointly opening the preset opening 16, allowing hot water or other substances to enter the bowl through the opening without causing irregular tearing or hot water splashing.
[0026] The top cover assembly 11 has a pull tab 17, and the first die-cut lines 14 extend from both sides of the root of the pull tab 17 onto the surface of the top cover assembly 11. Specifically, the pull tab 17 is an edge portion of the top cover assembly 11, protruding from the rim of the bowl for easy gripping by the user's fingers. The two first die-cut lines 14 start from both sides of the root of the pull tab 17 and extend toward the surface of the bowl lid 10, forming a symmetrical guide path, so that when the user pulls the pull tab 17, the top cover assembly 11 can be smoothly torn along the first die-cut lines 14.
[0027] The lower cover assembly 13 has a pinch handle 18, the base of which is provided with a third die-cut line 19. Specifically, the pinch handle 18 is an edge portion of the lower cover assembly 13, also protruding from the rim of the bowl, and corresponds to the position of the pull tab 17. For example, the protruding length of the pinch handle 18 matches that of the pull tab 17. The third die-cut line 19 is formed at the base of the pinch handle 18 by a die-cutting process, creating a pre-break line penetrating the lower cover assembly 13, such as a transverse tangent, the length of which covers the width of the base of the pinch handle 18, thus defining the boundary of the pinch handle 18. The pull tab 17 corresponds to the position of the pinch handle 18, and both ends of the third die-cut line 19 extend to both sides of the base of the pull tab 17. Specifically, the pull tab 17 and the gripper 18 are aligned in the thickness direction of the lid 10, and the user can grip the gripper 18 at the same time when gripping the pull tab 17; the two ends of the third die-cut line 19 extend to the positions corresponding to the two sides of the root of the pull tab 17, that is, corresponding to the starting positions of the two first die-cut lines 14, to ensure that the gripper 18 can work in coordination with the pull tab 17 during the opening process, so that the gripper 18 can be opened together with the lid assembly 11.
[0028] Through this structural design, the third die-cut line 19 defines the boundary of the gripper 18 on the lower cover assembly 13. When the user pinches the pull tab 17 of the upper cover assembly 11, they can simultaneously pinch the corresponding gripper 18 of the lower cover assembly 13 formed by the third die-cut line 19. When the user pulls the pull tab 17 upwards, the applied force acts simultaneously on both the upper cover assembly 11 and the lower cover assembly 13.
[0029] The specific opening process is as follows: The user pinches the pull tab 17 and the handle 18 below it and pulls upwards. At this time, the upper cover assembly 11 will begin to tear along the two first die-cut lines 14; simultaneously, the lower cover assembly 13, driven by the handle 18, will first break along the third die-cut line 19, causing the handle 18 to separate from the lower cover assembly 13, and be lifted up along with the upper cover assembly 11. As the user continues to pull backwards, the upper cover assembly 11 continues to tear along the first die-cut line 14. When the tearing force is transmitted to the second die-cut line 15, because the second die-cut line 15 passes through the lower cover assembly 13, the tearing of the lower cover assembly 13 will unfold in a controlled manner along the second die-cut line 15. In this way, the upper cover assembly 11 and the lower cover assembly 13 can be torn open synchronously and controllably along the preset opening path, thereby forming a regular-shaped and appropriately sized opening on the bowl lid 10, effectively avoiding the problems of difficult opening and uncontrollable opening of traditional bowl lids 10, resulting in hot water splashing, and improving the user experience.
[0030] In one embodiment, a release layer 20 is provided between the top cover assembly 11 and the adhesive layer 12 in a preset area; the orthographic projections of the first die-cutting line 14, the second die-cutting line 15 and the third die-cutting line 19 along the thickness direction of the bowl cover 10 all fall into the coating area of the release layer 20.
[0031] In this embodiment, the release layer 20 can be a low-tack area formed by applying a release agent to the lower surface of the upper cover assembly 11. The function of the release layer 20 is to reduce the adhesive strength (i.e., peel force) between the upper cover assembly 11 and the adhesive layer 12 in its area, forming an interface that is easy to separate. Outside the area coated with the release layer 20, the upper cover assembly 11 and the adhesive layer 12 still maintain a high adhesive strength to ensure the overall structural stability of the bowl lid 10.
[0032] The orthographic projections of the first die-cutting line 14, the second die-cutting line 15, and the third die-cutting line 19 along the thickness direction of the lid 10 all fall within the coating area of the release layer 20. Here, "orthographic projection" refers to the outline of each die-cutting line on a two-dimensional plane when viewed vertically downwards from directly above the lid 10. Although the second die-cutting line 15 and the third die-cutting line 19 are physically located on the lower cover assembly 13, their positions on the plane of the lid 10 completely coincide with and correspond to the uppermost (between the upper cover assembly and the adhesive layer 12) low-tack release layer 20 area.
[0033] The effect of this structural design is that when the user pulls the tongue 17 and pinches the handle 18 to open the lid 10, the tearing force mainly propagates along the die-cut lines. For the first die-cut line 14, since it is located on the upper cover assembly 11, the interface below its tear path is precisely the release layer 20, so the upper cover assembly 11 can easily peel off from the adhesive layer 12 while tearing. For the second and third die-cut lines 15 and 19 located on the lower cover assembly 13, when they begin to tear, the interface directly above their tear path, located between the upper cover assembly 11 and the adhesive layer 12, is precisely the pre-defined release layer 20 area. This ensures that when the lower cover breaks along the die-cut line, the upper cover assembly 11 above it can peel off synchronously and with low resistance, without the difficulty of tearing caused by the obstruction of the highly viscous adhesive layer 12.
[0034] This structure limits the interlayer separation during opening to the range of action of the release layer 20, avoiding problems such as incomplete tearing, path deviation, or damage to the cup lid 10 structure caused by the tearing path deviating to the high viscosity area, thus ensuring the smoothness, controllability, and reliability of the opening process.
[0035] In one embodiment, the lower cover assembly 13 includes a retaining portion 21 located between the second die-cutting line 15 and the third die-cutting line 19. A fourth die-cutting line 22 passes through the retaining portion 21 to form a latch. The latch is configured to accommodate the pull tab 17 and the pinch handle 18 after the bowl cover 10 is opened along the opening path. The two ends of the fourth die-cutting line 22 are respectively spaced from the first die-cutting line 14 by a preset interval.
[0036] In this embodiment, the lower cover assembly 13 includes a retaining portion 21 located between the second die-cutting line 15 and the third die-cutting line 19. This retaining portion 21 is part of the lower cover assembly 13 and is strip-shaped. When the user tears open the bowl lid 10 along the opening path, the inner portion surrounded by the second die-cutting line 15 is opened, while the retaining portion 21, together with the outer body of the lower cover assembly 13, continues to maintain a seal with the rim of the bowl and will not be torn off.
[0037] To achieve the locking function, a fourth die-cutting line 22 is provided on the retaining portion 21 to form a latch on the retaining portion 21. This fourth die-cutting line 22 is also a penetrating cut or pre-break line formed on the retaining portion 21 of the lower cover assembly 13 by a die-cutting process. This cut is the latch, or the latch is an opening formed after the fourth die-cutting line 22 breaks.
[0038] The latch is configured to accommodate the pull tab 17 and the gripper 18 after the bowl lid 10 is opened along the opening path. When the user partially opens the bowl lid 10 along the opening path formed by the first die-cut line 14, the second die-cut line 15, and the third die-cut line 19, a movable lid is formed, consisting of the pull tab 17 of the upper lid assembly 11, the gripper 18 of the lower lid assembly 13, and a partially torn lid body. A preset opening 16 is also formed, and the retaining part 21 remains fixed in its original position on the bowl lid 10. At this time, the user can fold this movable lid forward and insert its tip into the latch formed by the fourth die-cut line 22. Through this insertion, the opened movable lid is stably fixed, effectively reducing heat loss by blocking the opening with the lid itself. For example, after pouring hot water to brew food, the bowl lid 10 remains relatively closed, improving the heat retention effect.
[0039] To ensure structural stability and integrity, the two ends of the fourth die-cutting line 22 are respectively spaced apart from the first die-cutting line 14. In other words, the fourth die-cutting line 22 is an independent cut that does not connect with the first die-cutting line 14 that guides the tearing of the cover assembly 11. This design avoids the formation of a weak area due to the intersection of multiple die-cutting lines, thereby preventing accidental tearing of the retaining part 21 during opening and ensuring the overall reliability of the bowl lid 10 structure.
[0040] In one embodiment, the orthographic projection of the fourth die-cutting line 22 along the thickness direction of the bowl lid 10 falls into the coating area of the release layer 20.
[0041] In this embodiment, the orthographic projection refers to the projection of the outline of the fourth die-cut line 22 onto the plane when viewed vertically downwards from directly above the lid 10, where the projection lies entirely within the boundary of the release layer 20 coating area. Although the fourth die-cut line 22 is physically located on the lower cover assembly 13, its position on the plane of the lid 10 corresponds perfectly to the release layer 20 area on the upper layer (between the upper cover assembly and the adhesive layer 12). This means that the interface between the upper cover assembly 11 and the adhesive layer 12 directly above the area where the fourth die-cut line 22 is located has been pre-coated with release agent, forming a low-tack area.
[0042] The effect of this structural design is that, although the fourth die-cut line 22 is mainly used to form the latch, its projection falling into the release layer 20 ensures that during the opening of the lid 10, if the tearing force indirectly affects the area around the retaining part 21, the interlayer separation in that area can also benefit from the low peeling force of the release layer 20. For example, when the user tears open the lid 10 along the opening path, the retaining part 21, as a fixed part, will not be completely peeled off. However, if a slight stress is transmitted to the vicinity of the fourth die-cut line 22, the release layer 20 can prevent the lid assembly 11 and the adhesive layer 12 from forming an unexpected strong bond at that point, thereby avoiding potential uneven tearing or structural damage. By incorporating the projection of the fourth die-cut line 22 into the effective range of the release layer 20, the reliability of the entire opening mechanism is further improved, preventing the retaining part 21 from accidentally detaching.
[0043] In one embodiment, the upper cover assembly 11 includes an upper cover body 24 located outside the first die-cutting line 14, and a first peelable portion 25 located inside the first die-cutting line 14; one edge of the first peelable portion 25 protrudes from the rim of the bowl body 31 to form the pull tab 17; the lower cover assembly 13 includes a lower cover body 26 corresponding to the upper cover body 24, and a second peelable portion 27 located inside the second die-cutting line 15; the lower cover body 26 forms the retaining portion 21 between the second die-cutting line 15 and the third die-cutting line 19, and one edge of the lower cover body 26 protrudes from the rim of the bowl body to form the pinch handle 18.
[0044] In this embodiment, the cover assembly 11 includes a cover body 24 located outside the first die-cut line 14 and a first peelable portion 25 located inside the first die-cut line 14. Specifically, the first die-cut line 14 serves as a pre-break line for the cover assembly 11, dividing the cover assembly 11 into the inner first peelable portion 25 and the outer cover body 24. The first peelable portion 25 is a part of the cover assembly 11, and its boundary is defined by the two first die-cut lines 14. When the user applies force to open the bowl lid 10, the first peelable portion 25 will separate from the cover body 24 along the first die-cut line 14, thereby being peeled off. One edge of the first peelable portion 25 protrudes from the rim of the bowl body 31 to form the pull tab 17, that is, the pull tab 17 serves as an extension edge of the first peelable portion 25, making it convenient for the user to pinch and apply force.
[0045] The lower cover assembly 13 includes a lower cover body 26 corresponding to the upper cover body 24, and a second peelable portion 27 located inside the second die-cut line 15. Specifically, the lower cover body 26 is the outer fixed part of the lower cover assembly 13, corresponding to the position of the upper cover body 24, and maintaining a seal with the rim of the bowl; the second peelable portion 27 is the inner part of the lower cover assembly 13, and its boundary is defined by the second die-cut line 15. When the user opens the bowl lid 10, the second peelable portion 27 will separate from the lower cover body 26 along the second die-cut line 15, thereby being peeled off. The lower cover body 26 forms a retaining portion 21 between the second die-cut line 15 and the third die-cut line 19. The retaining portion 21 is a part of the lower cover body 26 and is shaped as a ring-shaped area (e.g., an arc-shaped band). When the bowl lid 10 is opened, the retaining portion 21 remains fixed in place and will not be torn off. One edge of the lower cover body 26 protrudes from the rim of the bowl to form the pinch handle 18. That is, the pinch handle 18 is an extension edge of the lower cover body 26, corresponding to the position of the pull tab 17 of the upper cover assembly 11, so that the user can pinch the pull tab 17 and the pinch handle 18 at the same time.
[0046] With this partitioned design, during opening, the user pinches the pull tab 17 (i.e., the edge of the first peelable part 25) and the grip 18 (i.e., the edge of the lower cover body 26) and pulls upwards. First, the first peelable part 25 of the upper cover assembly 11 separates from the upper cover body 24 along the first die-cut line 14; simultaneously, the grip 18 of the lower cover assembly 13 separates from the lower cover body 26 along the third die-cut line 19 and is lifted up along with the first peelable part 25. As the tear progresses to the second die-cut line 15, the second peelable part 27 of the lower cover assembly 13 separates from the lower cover body 26 along the second die-cut line 15. In this way, the first peelable part 25, the grip 18, and the second peelable part 27 can be opened simultaneously, forming a preset opening 16, while the upper cover body 24 and the lower cover body 26 (including the retaining part) remain in place, ensuring the overall sealing and structural stability of the bowl lid 10 and avoiding unnecessary excessive tearing.
[0047] In one embodiment, the minimum distance between the nearest point of the first die-cutting line 14 and the coating edge of the release layer 20 is d1, where d1 ≥ 2 mm.
[0048] In this embodiment, in order to ensure the easy peelability of the area of the first die-cut line 14, and at the same time to avoid the excessive extension of the release layer 20 leading to a decrease in the overall structural stability of the bowl lid 10, the minimum distance between the nearest point of the first die-cut line 14 and the coating edge of the release layer 20 is d1, where d1 ≥ 2 mm.
[0049] This means that, in a plan view of the lid 10, the minimum distance from any point on the first die-cut line 14 to the boundary of the release layer 20 coating area is not less than 2 mm. In other words, the first die-cut line 14 is completely contained within the release layer 20 area, and its distance from the edge of the release layer 20 area is at least 2 mm. When the user tears open the lid assembly 11 along the first die-cut line 14, the tear path is always within the effective range of the low-adhesion release layer 20, ensuring smooth opening.
[0050] In one embodiment, the minimum distance between the second die-cutting line 15 and the nearest point of the coating edge of the release layer 20 is d2, where d2 ≥ 2 mm.
[0051] In this embodiment, by ensuring that d2 is not less than 2mm, a stable bonding transition zone can be formed on the outside of the second die-cutting line 15, ensuring that the lower cover assembly 13 is separated in a controlled manner along a predetermined path when it is opened and pushed to the second die-cutting line 15, while avoiding tearing and instability caused by the release layer 20 being too close to the boundary.
[0052] In one embodiment, the minimum distance between the nearest point of the third die-cutting line 19 and the coating edge of the release layer 20 is d3, where d3 ≥ 2 mm.
[0053] In this embodiment, the distance limitation ensures that the interlayer peeling in the area where the third die-cut line 19 is located proceeds stably within the range of the release layer 20, facilitating the formation of cracks and guidance during pinching; on the other hand, it preserves a sufficient normal bonding area outside the third die-cut line 19, improving the tear resistance of the boundary there and preventing edge curling from occurring in the initial opening section.
[0054] In one embodiment, the first die-cutting line 14 is symmetrically distributed along the center line of the bowl lid 10; the second die-cutting line 15 has an arc-shaped or U-shaped profile.
[0055] In this embodiment, the first die-cutting lines 14 are symmetrically distributed along the center line of the lid 10. Specifically, with a center line passing through the center of the lid 10 as the axis of symmetry, the two first die-cutting lines 14 are mirror-symmetrical in shape, length, and position relative to this center line. This symmetrical design ensures that the tearing force applied to the two first die-cutting lines 14 is evenly distributed when the user pulls the tongue 17 from the middle position. This not only makes the tearing process of the lid assembly 11 smoother and less prone to deviation, but also ensures that the opening formed after tearing has good symmetry.
[0056] Furthermore, the second die-cutting line 15 has an arc or U-shaped profile. Specifically, the second die-cutting line 15 located on the lower cover assembly 13 has an overall routing that is either an arc or an upward-opening U-shape (viewed from above). This arc or U-shaped design not only matches the distribution and shape of the two die-cutting lines, but also facilitates the user in subsequently pouring hot water or removing food.
[0057] In summary, by designing the first die-cutting line 14 to be symmetrically distributed and making the second die-cutting line 15 arc-shaped or U-shaped, this embodiment ensures the controllability and stability of the opening process, while also taking into account ergonomics, further improving the overall quality of the product.
[0058] like Figure 7 As shown, corresponding to the above-mentioned bowl lid, this utility model embodiment provides a bowl, specifically a convenient food packaging bowl, which includes a bowl body 31 and a bowl lid 10 covering the rim of the bowl body 31.
[0059] In this embodiment, the bowl 31 can be a conventional container used in the prior art for holding instant noodles, instant rice noodles, self-heating porridge, and other foods. The bowl 31 has an internal space for holding food, an open rim, and a rim surrounding the rim.
[0060] The bowl lid 10 is the same as the bowl lid 10 described in the aforementioned embodiment. In specific applications, the bowl lid 10 is heat-pressed or glued to the rim of the bowl body 31 to seal the food (such as noodles, seasoning packets, etc.) inside the bowl body 31, forming a complete product ready for sale.
[0061] When the user needs to consume the food, they can directly operate the bowl lid 10 as described in the aforementioned embodiments to easily open the preset opening 16 for subsequent brewing and heat preservation. For example, the user can pinch the pull tab 17 and the grip 18 to tear open the bowl lid 10 along the opening path formed by the first die-cut line 14, the second die-cut line 15, and the third die-cut line 19, forming a neat opening for easy pouring of hot water. After pouring in hot water, the user can also fold the opened portion and insert it into the latch for fixation, thereby achieving a better heat preservation effect.
[0062] 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.
