Description

Technical Field

[0001] This utility model relates to the field of food container technology, specifically a sealing lid structure for a bowl-shaped bird's nest. Background Technology

[0002] Currently, canned food packaging is difficult or even impossible to open under vacuum. Even if tools are used, it is easy to cut fingers and cause unnecessary injury. As a ready-to-eat bird's nest product, bowl-shaped containers are usually used for packaging. The sealing structure of the container directly affects the product's shelf life, ease of consumption, and quality stability.

[0003] Chinese Utility Model Patent Publication No. CN206126808U discloses a vacuum opening structure for bowl-shaped bird's nest. The specification describes a structure that abandons plastic materials and uses glass for the bowl body. The bowl lid features a protruding, easy-to-press pressing part. A metal needle corresponding to the pressing part is located on the inner surface of the lid. Pressing causes the metal needle to pierce the vacuum-sealed lid, providing a simple opening method. However, while this vacuum opening structure for bowl-shaped bird's nest allows for quick opening by piercing the seal with the metal needle, the operation is cumbersome. Furthermore, placing a metal needle in each bowl increases production costs, hindering its widespread use. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a sealing cap structure for bird's nest bowls. It can effectively solve the problems in the prior art, which not only involves cumbersome operation steps using metal needles, but also requires placing metal needles in each serving of bird's nest bowls, which easily leads to high production costs and makes it inconvenient to promote and use.

[0005] The technical solution adopted by this utility model is: a sealing cover structure for a bowl-shaped swallow, including a bowl body and a bowl cover that matches the bowl body. An extension edge and a raised edge are provided at the upper edge of the bowl body. A fastening edge is fixedly installed downward at the edge of the bowl cover. An inner protrusion and an outer protrusion are fixedly installed at the center of the bowl cover. A through groove is opened from top to bottom at one end of the bowl cover near the inner and outer protrusions. A sealing film is provided at the end of the outer protrusion away from the bowl cover. The bowl cover is placed directly above the bowl body.

[0006] Preferably, a fastening groove is provided between the bowl lid and the fastening edge, and the fastening groove overlaps with the extension edge.

[0007] Through the above technical solution, the design of the interlocking groove and the extended edge allows the bowl body and the bowl lid to be initially positioned when they are closed, and the bowl lid can be easily placed on top of the bowl body, which facilitates subsequent negative pressure bonding.

[0008] Preferably, the upper edge of the bowl body and the cross-section of the bowl lid are in a circular shape, and a bowl support is fixedly installed at the end of the bowl body away from the bowl lid.

[0009] The above technical solution ensures that the upper edge of the bowl with a circular cross-section matches the bowl lid, ensuring even force distribution when the lid is closed and avoiding gaps that could lead to air leakage. In addition, the bowl support design enhances the stability of the bowl when placed, preventing it from tipping over, while also increasing the hand area for easier handling when taking out the bowl.

[0010] Preferably, the sealing film is an aluminum foil, the sealing film is located directly above the through groove, and the diameter of the sealing film is the same as the diameter of the outward protrusion.

[0011] The above technical solution involves covering the channel with a sealing film made of aluminum foil and fitting it to the outward protrusion. By utilizing the sealing and barrier properties of aluminum foil, it not only facilitates sealing and prevents the contents of the bowl from oxidizing and deteriorating, but also avoids leakage caused by insufficient sealing area when it covers the top of the channel, thus affecting its normal use.

[0012] Preferably, a raised edge is fixedly installed at the outer edge of the sealing film, and the raised edge fits against the inner protrusion and the bowl lid.

[0013] The above technical solution uses the raised edge of the sealing film to fit with the inner protrusion and the bowl cover to form an annular sealing strip, which further enhances the sealing performance of the through groove. In use, the user can peel off the sealing film through the raised edge, which can make the negative pressure inside disappear. This facilitates quick opening and closing, simplifies the operation steps, reduces production costs, and improves its practicality.

[0014] Preferably, the inner protrusion and the outer protrusion have the same shape and the same thickness.

[0015] The above technical solution uses inner and outer protrusions of the same shape and thickness to form a symmetrical support structure, which can balance the force on the sealing film and avoid local damage to the sealing film caused by the asymmetry of the protrusion structure.

[0016] Preferably, the bowl body and the bowl lid are bonded together by negative pressure, and an outer edge is fixedly installed on the end of the bowl body away from the inner protrusion.

[0017] Through the above technical solution, the negative pressure fit between the bowl body and the lid allows them to adhere tightly and form a seal. Atmospheric pressure is used to further prevent air from entering, and the outer edge increases the structural strength of the bowl body edge, making it easier to apply force when closing the lid.

[0018] Compared with the prior art, this utility model provides a sealing cap structure for a bowl-shaped bird's nest, which has the following beneficial effects:

[0019] 1. The sealing lid structure of this bowl-shaped bird's nest uses negative pressure to ensure a tight seal between the bowl and the lid, further preventing air from entering. An aluminum foil sealing film covers the channel and fits against the outward protrusion. The sealing and barrier properties of the aluminum foil not only facilitate sealing and prevent oxidation and deterioration of the contents of the bowl-shaped bird's nest, but also cover the channel directly above it, avoiding insufficient sealing area and leakage that could affect its normal use.

[0020] 2. The sealing cap structure of this bowl-shaped bowl is formed by the raised edge of the sealing film fitting with the inner raised part and the bowl lid to form an annular sealing band, which further enhances the sealing performance of the through groove. In use, the user can peel off the sealing film through the raised edge, which can make the negative pressure inside disappear. This facilitates quick opening and closing, simplifies the operation steps, reduces production costs, and improves its practicality. Attached Figure Description

[0029] 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, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1: As Figure 1-7 As shown, the present invention provides a sealing cover structure for a bowl-shaped swallow, including a bowl body 1 and a bowl cover 5 that matches the bowl body 1. An extension edge 3 and a raised edge 4 are provided at the upper edge of the bowl body 1. A fastening edge 7 is fixedly installed downward at the edge of the bowl cover 5. An inner protrusion 8 and an outer protrusion 10 are fixedly installed at the center of the bowl cover 5. A through groove 9 is provided from top to bottom at one end of the bowl cover 5 near the inner protrusion 8 and the outer protrusion 10. A sealing film 11 is provided at the end of the outer protrusion 10 away from the bowl cover 5. The bowl cover 5 covers the bowl body 1 directly above it.

[0031] Specifically, a fastening groove 6 is provided between the bowl lid 5 and the fastening edge 7. The fastening groove 6 overlaps with the extension edge 3. The advantage is that, through the design of the fastening groove 6 and the extension edge 3, when the bowl body 1 and the bowl lid 5 are closed, the cooperation between the two can play a preliminary positioning role, and it is convenient for the bowl lid 5 to overlap directly on the top of the bowl body 1, which is convenient for subsequent negative pressure bonding treatment.

[0032] Specifically, the upper edge of the bowl body 1 and the bowl lid 5 have a "circular" cross-section. A bowl support 2 is fixedly installed at the end of the bowl body 1 away from the bowl lid 5. The advantage is that by matching the upper edge of the bowl body 1 with the bowl lid 5 through the circular cross-section, the force is evenly distributed when the lid is closed, avoiding gaps that could lead to air leakage. In addition, the design of the bowl support 2 can improve the stability of the bowl body 1 when it is placed, prevent it from tipping over, and increase the hand area, making it easier to hold when taking out the bowl.

[0033] Specifically, the sealing film 11 is made of aluminum foil. The sealing film 11 is located directly above the through groove 9. The diameter of the sealing film 11 is the same as the diameter of the outer protrusion 10. The advantage is that by covering the through groove 9 with the sealing film 11 made of aluminum foil and fitting it to the outer protrusion 10, the sealing and barrier properties of aluminum foil not only facilitate sealing and prevent the contents of the bowl from oxidizing and deteriorating, but also avoid leakage caused by insufficient sealing area when it is directly above the through groove 9, thus affecting its normal use.

[0034] Example 2: Figure 2-7 As shown, this is an improvement on the previous embodiment.

[0035] Specifically, a raised edge 12 is fixedly installed on the outer edge of the sealing membrane 11. The raised edge 12 fits against the inner protrusion 8 and the bowl cover 5. The advantage is that the raised edge 12 of the sealing membrane 11 fits against the inner protrusion 8 and the bowl cover 5 to form an annular sealing band, which further enhances the sealing performance of the through groove 9. In use, the user can peel off the sealing membrane 11 through the raised edge 12, which can make the internal negative pressure disappear. This facilitates quick opening and closing, simplifies the operation steps, reduces production costs, and improves its practicality.

[0036] Specifically, the inner protrusion 8 and the outer protrusion 10 have the same shape and the same thickness. The advantage is that the inner protrusion 8 and the outer protrusion 10, which have the same shape and thickness, form a symmetrical support structure, which can balance the force on the sealing membrane 11 and avoid local damage to the sealing membrane 11 caused by the asymmetry of the protrusion structure.

[0037] Specifically, the bowl body 1 and the bowl lid 5 are bonded together by negative pressure. An outer edge 13 is fixedly installed at the end of the bowl body 1 away from the inner protrusion 8. The advantage is that the negative pressure bonding between the bowl body 1 and the bowl lid 5 makes the two adhere tightly and form a seal. Atmospheric pressure is used to further prevent air from entering. The outer edge 13 increases the structural strength of the edge of the bowl body 1, making it easier to apply force when closing.

[0038] Working Principle: During use, the design of the interlocking groove 6 and the extension edge 3 allows for initial positioning when the bowl body 1 and the bowl lid 5 are closed. This facilitates the lid 5 to overlap the bowl body 1, enabling subsequent negative pressure bonding. The circular cross-section of the bowl body 1 and the bowl lid 5 ensure even force distribution during closing, preventing gaps and air leakage. The bowl support 2 enhances the stability of the bowl body 1, preventing tipping, and increases the hand area for easier handling. The aluminum foil sealing film 11 covers the through groove 9 and adheres to the outward protrusion 10. The aluminum foil's sealing and barrier properties not only facilitate sealing and prevent oxidation and deterioration of the contents, but also cover the through groove 9, minimizing the sealing area. Insufficient sealing can lead to leakage, affecting normal use. The raised edge 12 of the sealing membrane 11 fits with the inner protrusion 8 and the bowl cover 5 to form an annular sealing band, further enhancing the sealing performance of the through groove 9. During use, the user can peel off the sealing membrane 11 through the raised edge 12, which can eliminate the internal negative pressure, making it easy to open and close quickly, simplifying the operation steps, reducing production costs, and improving its practicality. The inner protrusion 8 and the outer protrusion 10, which are of the same shape and thickness, form a symmetrical support structure, which can balance the force on the sealing membrane 11 and avoid local damage to the sealing membrane 11 caused by the asymmetry of the protrusion structure. The negative pressure fit between the bowl body 1 and the bowl cover 5 makes them tightly adhered and form a seal. Atmospheric pressure is used to further prevent air from entering. The outer edge 13 increases the structural strength of the edge of the bowl body 1, making it easier to apply force when closing.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
