Abstract
Description
Technical Field
[0001] This utility model relates to the field of gaiwan technology, and in particular to an inner-lifting drain bowl lid and a water-filtering gaiwan. Background Technology
[0002] With the continued growth in consumer demand for convenience foods (such as instant noodles, instant soup, and self-heating rice), the functional integrity, ease of use, and production stability of bowl lids, as a core component of convenience food packaging, have become a key focus of the industry. Among them, bowl lids with drainage functions are gradually becoming the mainstream design direction because they can meet users' needs to drain excess soup after soaking (such as mixing seasoning after draining instant noodles, or draining and seasoning ready-made dishes).
[0003] For example, the patent publication number is CN120081093A, the application date is April 21, 2025, and the patent name is a drainage covered bowl and its preparation method. The above patent document discloses a covered bowl structure, which divides the bowl lid film into drainage sheets and corresponding handles by setting a knife line. Users can lift the drainage sheets by pinching the handles to drain water, which is convenient to use.
[0004] However, the above patent documents still have the following shortcomings: (1) High scrap rate: The handle usually protrudes from the edge of the lid or is located on the outer side of the lid. To separate the handle from the drain sheet and the main body of the lid, an additional cutting line is needed to separate the handle from the edge of the lid (i.e., at least three cutting lines are required: one to separate the drain sheet from the main body, one to separate the handle from the edge, and one to cut the drain opening). The increase in the number of cutting lines directly leads to problems such as cutting line misalignment, breakage, and membrane delamination during the membrane processing, which significantly increases the scrap rate and the production cost of the enterprise.
[0005] (2) The drain sheet is prone to fall off in advance during transportation: Since the handle is located on the outside of the bowl lid, during storage and transportation, the external force (such as squeezing, collision and friction) when the bowl lid is stacked and handled is likely to directly act on the handle on the outside, causing the handle to pull the drain sheet to separate from the bowl lid body in advance, affecting the sealing of the bowl lid (the fallen drain sheet may damage the edge sealing structure). Utility Model Content
[0006] This utility model provides an internally hinged drain bowl lid, which aims to solve the problem that the handle of the existing drain bowl lid protrudes from the edge of the lid, resulting in a high scrap rate during production and the drain sheet easily separating prematurely during transportation.
[0007] To achieve the above objectives, the present invention adopts the following technical solution: In a first aspect, the present invention provides an inner-lifting drain bowl lid, comprising: a lower film, an adhesive layer and an upper film stacked sequentially from bottom to top; The upper membrane is provided with a first cutting line that divides it into an upper membrane body and a drain sheet; the drain sheet is provided with a pinch handle, which is located within the area of the upper membrane; The lower membrane is provided with a plurality of second cutting lines, which divide the lower membrane into a lower membrane body and a plurality of peelable sheets; the plurality of peelable sheets correspond to the positions of the draining sheets; The adhesive layer is provided with a third cutting line corresponding to the second cutting line; A release layer is provided on the side of the adhesive layer facing the upper film. A first through area corresponding to a plurality of peelable sheets is provided through the release layer. The adhesive layer passes through the first through area to bond the peelable sheets and the drain sheet together.
[0008] In one embodiment, the projection of the drain sheet toward the release layer falls entirely within the area of the release layer.
[0009] In one embodiment, the first through region includes a plurality of parallel elongated adhesive regions, and a plurality of peelable sheets correspond to a plurality of elongated adhesive regions; the projection of each elongated adhesive region toward the lower film falls entirely within the area of the peelable sheet corresponding to it.
[0010] In one embodiment, the release layer is further provided with a second through area surrounding the first through area, and the adhesive layer passes through the second through area to adhere to the drain sheet.
[0011] In one embodiment, the entire space enclosed by the second through-area is located within the projection area of the drain sheet; the minimum distance between the end of the pinch handle and the second through-area is d3, where d3 > 5 mm.
[0012] In one embodiment, the minimum distance between the edge of the release layer and the edge of the drain sheet is d1, where d1 > 2 mm.
[0013] In one embodiment, the minimum distance between the edge of the peelable sheet and the edge of the elongated adhesive area is d2, where d2 > 1 mm.
[0014] In one embodiment, the pinch handle gradually curves upwards in a direction away from the upper film, and the vertical distance between the end of the pinch handle and the upper film is d4, where d4 > 1 mm.
[0015] In one embodiment, the plurality of elongated adhesive regions are arranged along the radial direction of the upper film.
[0016] Secondly, this utility model embodiment also provides a water filter bowl, including a bowl body, on which the above-mentioned inner-lifting drain bowl cover is provided, and the edge of the inner-lifting drain bowl cover is provided with a pull tab protruding from the bowl body, and the pull tab and the peelable piece are provided at both ends of the inner-lifting drain bowl cover in the radial direction.
[0017] The advantages of this utility model compared with the prior art are: (1) Simplified process and improved yield: The gripper is integrally formed when the first cutting line is cut, without the need for additional processing steps. This avoids problems such as cutting line misalignment, breakage or film delamination caused by multiple processing steps, and significantly reduces the scrap rate.
[0018] (2) Avoid accidental separation and more reliable sealing: The handle is designed on the inside of the bowl lid. During storage and transportation, even if it is subjected to external forces such as stacking, squeezing, collision or friction, it will not directly act on the handle, thus effectively preventing the drain sheet from being accidentally opened in advance and ensuring the complete sealing of the bowl lid before it reaches the consumer.
[0019] (3) Easy to operate and easy to identify: the hand part naturally lifts up (d4>mm), providing users with a clear point of force. No need to search, it can be lifted up with a pinch, reducing the operating resistance.
[0020] (4) Highly efficient drainage and leak-proof: The first through-zone is designed as a parallel strip, which can ensure smooth and orderly drainage and effectively prevent long and thin food (such as noodles) from leaking out of the hole.
[0021] (5) Smooth peeling: The design of the second through zone ensures that the adhesive layer and the drain sheet have sufficient bonding area, which not only prevents them from loosening, but also ensures that the force is even when peeling, and the tearing process is smooth.
[0022] The above description is only an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model, it can be implemented according to the contents of the specification. In order to make the above and other objects, features and advantages of this utility model more obvious and understandable, the following are preferred embodiments, which are described in detail below.

[0028] 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.
[0029] Please see Figure 1-5 This utility model provides an inner-lifting drain bowl lid, comprising: a lower film 1, an adhesive layer 2, and an upper film 3 stacked sequentially from bottom to top; The upper membrane 3 is provided with a first cutting line 31 that divides it into an upper membrane body 33 and a drain sheet 32; the drain sheet 32 is provided with a pinch handle 321, which is located within the area of the upper membrane 3; The lower membrane 1 is provided with a plurality of second cutting lines 11, which divide the lower membrane 1 into a lower membrane body 13 and a plurality of peelable sheets 12; the plurality of peelable sheets 12 are positioned corresponding to the drain sheet 32. The adhesive layer 2 is provided with a third cutting line 21 corresponding to the second cutting line 11; A release layer 4 is provided on the side of the adhesive layer 2 facing the upper film 3. A first through area 41 corresponding to a plurality of peelable sheets 12 is provided through the release layer 4. The adhesive layer 2 passes through the first through area 41 to bond the peelable sheets 12 and the drain sheet 32 together.
[0030] In this embodiment, by placing the handle 321 within the area of the upper film 3, the structure of the handle 321 can be completed during processing only when the first cutting line 31 is processed on the upper film 3. This eliminates the need for additional cutting lines, reducing the likelihood of problems such as cutting line misalignment, breakage, and film delamination during processing, thus significantly reducing the scrap rate. Furthermore, since the handle 321 is located inside the lid, external forces (such as squeezing, collision, and friction) during stacking and handling of the lids in storage and transportation will not directly affect the handle 321, preventing premature separation of the drain sheet 32 from the lid body and thus maintaining the lid's sealing performance.
[0031] Specifically, in this embodiment, the adhesive layer 2 has a high adhesiveness and is used to bond the upper film 3 and the lower film 1 together to form an integral structure. The release layer 4 is used to reduce the adhesive force of the adhesive layer 2 on the upper film 3 or the lower film 1. When processing the first cutting line 31, an outwardly protruding gripper 321 is formed on the periphery of the drain sheet 32. By pinching the gripper 321, the drain sheet 32 can be easily peeled off.
[0032] In addition, in this embodiment, the positions of the second cutting line 11 and the third cutting line 21 completely overlap, so that the first cutting line 11 and the third cutting line 21 can be processed simultaneously.
[0033] In a further embodiment, the first through region 41 includes a plurality of parallel elongated adhesive regions, and a plurality of peelable sheets 12 correspond to a plurality of elongated adhesive regions; the projection of each elongated adhesive region toward the lower film 1 falls entirely within the area of the peelable sheet 12 corresponding to it.
[0034] In this embodiment, the first through area 41 is set as several long strip-shaped adhesive areas, so that when the drain sheet 32 is torn off, a long strip-shaped drain net can be formed on the release layer 4, so that when draining, the food (such as noodles) in the bowl is not easy to leak out from the long strip-shaped adhesive areas.
[0035] In addition, the outline of the elongated adhesive area in this embodiment is smaller than the outline of the corresponding peelable sheet 12. This can prevent the adhesive layer 2 from connecting with the lower film body 13 on the periphery of the peelable sheet 12, so that the peelable sheet 12 can be easily peeled off when the drain sheet 32 is peeled off.
[0036] In this embodiment, as Figure 2 As shown, the minimum distance between the edge of the peelable sheet 12 and the edge of the elongated adhesive area is d2, where d2 > 1 mm.
[0037] In this embodiment, the plurality of elongated adhesive regions are arranged along the radial direction of the upper film 3.
[0038] This allows water to drain out in an orderly manner along several long, sticky zones during the draining process.
[0039] In a further embodiment, the release layer 4 is further provided with a second through area 42 surrounding the first through area 41, and the adhesive layer 2 passes through the second through area 42 and adheres to the drain sheet 32.
[0040] The second through area 42 is a closed hollow strip set on the release layer 4, surrounding the periphery of several long strip adhesive areas, so that the adhesive layer 2 can directly adhere to the drain sheet 32, which not only prevents the drain sheet 32 from loosening, but also ensures the smoothness when the drain sheet 32 is peeled off.
[0041] The entire space enclosed by the second through area 42 is located within the projection area of the drain sheet 32; the minimum distance between the end of the handle 321 and the second through area 42 is d3, where d3 > 5 mm.
[0042] In this embodiment, the end of the gripping part 321 is left with a distance from the second through area 42. Within this distance range, it directly contacts the release layer 4, so that the drain sheet 32 can be easily gripped by hand and then easily torn off.
[0043] In a further embodiment, such as Figure 5 As shown, the pinch handle 321 gradually curves upwards in the direction away from the upper film 3, and the vertical distance between the end of the pinch handle 321 and the upper film 3 is d4, where d4 > 1 mm.
[0044] Because there is a distance between the end of the handle 321 and the second through area 42, the handle 321 within this distance range corresponds to the release layer 4. Therefore, the handle 321 will be slightly raised under normal conditions, and the maximum distance between the highest point of the raised part and the surface of the upper film 3 of the bowl lid is d4, which is greater than 1mm. This design allows the user to pinch the handle 321 more easily without having to fumble for the position, reducing the operating resistance when peeling off the drain sheet 32.
[0045] In another embodiment, this utility model also provides a water-filtering bowl, including a bowl body, on which the aforementioned inner-lifting drain bowl lid is provided. The edge of the inner-lifting drain bowl lid is provided with a pull tab 5 protruding from the bowl body. The pull tab 5 and the peelable piece 12 are located at both ends of the inner-lifting drain bowl lid in the radial direction.
[0046] In this embodiment, the drain bowl is used in conjunction with the inner-opening drain bowl lid. Since the handle 321 is located inside the bowl lid, during storage and transportation, external forces (such as squeezing, collision, and friction) during stacking and handling of the bowl lid will not directly affect the handle 321, preventing the handle 321 from prematurely separating the drain sheet 32 from the bowl lid body, thus not affecting the sealing performance of the bowl lid. In addition, a pull tab 5 protruding from the bowl body is provided on the edge of the inner-opening drain bowl lid, making it easy to open the bowl. At the same time, the pull tab 5 and the peelable piece 12 are located at both ends of the inner-opening drain bowl lid in the radial direction. When the inner-opening drain bowl lid is opened from one end, the sealing performance between the inner-opening drain bowl lid and the bowl body at the peelable piece 12 at the other end is not affected, facilitating drainage.
[0047] It should be noted that in this embodiment, the drain sheet 32 can be configured into different shapes according to usage requirements, such as... Figure 6 and Figure 7As shown, the drain sheet 32 is configured in a crescent shape distributed along the edge of the bowl lid.
[0048] Compared with the prior art, this application has the following advantages: (1) Simplified process and improved yield: The gripper 321 is integrally formed when cutting the first cutting line 31, without the need for additional processing steps. This avoids problems such as cutting line misalignment, breakage or film delamination caused by multiple processing steps, and significantly reduces the production scrap rate.
[0049] (2) Avoid accidental separation and more reliable sealing: The handle 321 is designed inside the bowl lid. During storage and transportation, even if it is subjected to external forces such as stacking, squeezing, collision or friction, it will not directly act on the handle, thereby effectively preventing the drain sheet 32 from being accidentally opened in advance and ensuring the complete sealing of the bowl lid before it reaches the consumer.
[0050] (3) Easy to operate and easy to identify: the hand part 321 naturally lifts up (d4>1mm), providing users with a clear point of force. No need to search, it can be lifted up with a pinch, reducing the operating resistance.
[0051] (4) Highly efficient drainage and leak-proof: The first through-zone 41 is designed as a parallel strip, which can ensure smooth and orderly drainage and effectively prevent long and thin food (such as noodles) from leaking out of the hole.
[0052] (5) Smooth peeling: The design of the second through area 42 ensures that the adhesive layer 2 and the drain sheet 32 have sufficient bonding area, which not only prevents them from loosening, but also ensures that the force is uniform when peeling, and the tearing process is smooth.
[0053] 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.
