Lunchbox lid structure

Abstract

A lid structure for a lunchbox includes a lid body with a sealing ring at the bottom for fitting and fixing to the top of a lunchbox. A platform protrudes above the sealing ring, and a plurality of limiting protrusions are provided on the upper surface of the platform. Each limiting protrusion is adjacent to the periphery of the platform and is not flush with the ring wall, thereby forming a stacking step on the outer edge of the limiting protrusions and the upper surface of the platform to allow for the stacking of another lunchbox. The limiting protrusions are spaced apart to define a straight space for placing a pair of chopsticks, so that the chopsticks can be securely attached to the lid body, eliminating the inconvenience of holding them by hand and preventing the chopsticks from being lost from the lunchbox, greatly improving the practicality of the lid body and the convenience of using the chopsticks.

Description

Lunchbox lid structure Technical Field

[0001] This work concerns a container structure, particularly the lid structure of a lunchbox. Prior Technology

[0002] Traditional lunchboxes consist of a lid and a body. The body holds the food, which is then sealed by the lid. The lid typically has a top and a side extending from the outer edge of the top towards the body. This side covers the upper perimeter of the body, securing the lid and achieving a seal. A pair of chopsticks or other utensils are usually included with the meal. However, the surface of traditional lunchbox lids is usually flat or simply recessed, lacking a dedicated structure for securing chopsticks. Therefore, chopsticks are often simply placed on top of the lid or inserted into a rubber band. During transport or delivery, chopsticks easily slip or fall, causing hygiene concerns and inconvenience. Furthermore, when multiple lunchboxes are stacked, if chopsticks are already on top of the lid, the bottom of the upper lunchbox cannot fit flush with the lid of the lower lunchbox, resulting in instability and a tendency to tip over. Therefore, how to design a system that can both position chopsticks and improve stacking stability is a problem that relevant manufacturers urgently need to solve.

[0003] In view of this, based on my years of experience in manufacturing, developing and designing related products, and after careful design and evaluation for the above objectives, I have finally come up with this work which is indeed practical. Summary of the Invention

[0004] The technical problem this invention aims to solve is to address the aforementioned deficiencies in existing technologies by providing a lid structure for a lunchbox. This structure includes a lid with a sealing ring at the bottom for fitting and fixing to the top of a lunchbox. A platform protrudes above the sealing ring, and a ring wall connects the sealing ring to the platform. A plurality of limiting protrusions are provided on the upper surface of the platform. Each limiting protrusion is adjacent to the periphery of the platform but not flush with the ring wall, thereby forming a stacking step on the outer edge of the limiting protrusions and the upper surface of the platform, which allows for the stacking and positioning of another lunchbox. Furthermore, the limiting protrusions are spaced apart to define a straight space for placing a pair of chopsticks.

[0005] Preferably, the upper surface of the platform of the cover is provided with four limiting protrusions. The limiting protrusions are symmetrically arranged in pairs on both sides of the platform. The two limiting protrusions on the same side do not come into contact with each other and have a gap, and the gaps are connected and located on the same straight line to form the straight space.

[0006] Preferably, the lid can be further secured to the lunchbox by a rubber band, which is perpendicular to the chopsticks and simultaneously tightens and positions the chopsticks.

[0007] Preferably, the cover body without the limiting protrusion has two positioning recesses symmetrically provided on the other two sides by the platform and the ring wall, and the two positioning recesses are used for positioning when the rubber band is coiled.

[0008] Preferably, the upper surface of the platform of the cover is provided with two raised protrusions between the limiting protrusions on both sides, the height of the raised protrusions is lower than that of the limiting protrusions, and the raised protrusions are located on the loop path of the rubber band.

[0009] Preferably, the platform of the cover is further recessed along the gap and the straight space to provide a chopsticks groove, so that when the chopsticks are placed in the chopsticks groove, they are indeed lower than the platform, which helps to improve the stability of the stacking limit of the other lunch box.

[0010] Compared with the effects of previous technologies, the lid of this invention, through the design of the platform and multiple limiting protrusions, defines a stacking step that can stably provide another lunchbox for stacking. The gaps formed by the spaced arrangement of the limiting protrusions facilitate the placement and positioning of the chopsticks, so that the chopsticks can be securely attached to the lid, eliminating the inconvenience of holding them by hand and preventing the chopsticks from being lost from the lunchbox. This greatly improves the practicality of the lid and the convenience of using the chopsticks. Simple Explanation of the Diagram

[0020] To enable your review committee to gain a deeper understanding of the purpose, characteristics, and effects of this work, please provide the following detailed explanation in conjunction with the accompanying illustrations:

[0021] First, as shown in Figures 1, 2, and 3, a lid structure for a lunchbox includes a lid 10. The bottom of the lid 10 has a sealing ring 11 for fitting and fixing to a lunchbox 20. A platform 12 protrudes above the sealing ring 11. A ring wall 121 connects the sealing ring 11 to the platform 12. The upper surface of the platform 12 has a plurality of limiting protrusions 13. Each limiting protrusion 13 is adjacent to the periphery of the platform 12 and is not flush with the ring wall 121. Thus, the outer edge of the limiting protrusion 13 and the upper surface of the platform 12 form a stacking step 14 that allows another lunchbox 20 to be stacked and positioned. The limiting protrusions 13 are spaced apart to define a straight space for placing a pair of chopsticks 30.

[0022] The structural embodiment is further illustrated in Figures 2, 4, and 5. The upper surface of the platform 12 of the cover 10 is provided with four limiting protrusions 13. The limiting protrusions 13 are symmetrically arranged in pairs on both sides of the platform 12. The two limiting protrusions 13 on the same side do not come into contact with each other and have a gap 131. The gaps 131 between the two limiting protrusions 13 on both sides are connected and located on the same straight line to form a straight space for placing and positioning the chopsticks 30. The cover 10 can be further fixed to the lunch box 20 by a rubber band 40. When the rubber band 40 is wrapped, it is perpendicular to the chopsticks 30, and at the same time, the rubber band 40 is used to tighten and position the chopsticks 30. The above-mentioned design of four limiting protrusions 13 is only one preferred embodiment and should not be limited to it. At least two limiting protrusions 13 can be used to define the straight space for placing the chopsticks 30.

[0023] Furthermore, in a further explanation of the above-mentioned design embodiment of the four limiting protrusions 13, the other two sides of the cover 10 without the limiting protrusions 13 are symmetrically provided with two positioning recesses 122 by the platform 12 and the annular wall 121. The two positioning recesses 122 are used for positioning when the rubber band 40 is coiled. Furthermore, the upper surface of the platform 12 of the cover 10 is provided with two raised protrusions 123 between the limiting protrusions 13 on both sides. The height of the two raised protrusions 123 is lower than that of the limiting protrusions 13, and the two raised protrusions 123 are located on the coiling path of the rubber band 40. When the rubber band 40 is coiled, it can simultaneously abut against the chopsticks 30 and the two raised protrusions 123, so that the rubber band 40 is not attached to the platform 12, so that the rubber band 40 can be pulled away from the cover 10, thereby achieving the purpose of quick disassembly of the rubber band 40.

[0024] Furthermore, the lid 10 has several variations depending on the shape of the lunch box 20. For example, Figures 1 and 2 show a circular lunch box 20 with a circular lid 10; and Figures 5 and 6 show a square lunch box 20 with a square lid 10.

[0025] Another embodiment of its structure, as shown in Figures 7 and 8, has a chopstick groove 124 recessed downward along the gap 131 and the straight space of the cover 10. When the chopsticks 30 are placed in the chopstick groove 124, they are indeed lower than the platform 12, which helps to improve the stability of the stacking limit of the other lunch box 20.

[0026] By utilizing the structure of the above-described specific embodiment, the following benefits can be obtained: The lid 10 of this invention, through the design of the platform 12 and a plurality of limiting protrusions 13, defines a stacking step 14 that can stably provide another lunch box 20 for stacking, and utilizes the gaps 131 formed by the spaced arrangement of the limiting protrusions 13 to facilitate the placement and positioning of the chopsticks 30, so that the chopsticks 30 can be reliably attached to the lid 10, eliminating the inconvenience of holding them by hand, and preventing the chopsticks from being lost from the lunch box, greatly improving the practicality of the lid 10 and the convenience of using the chopsticks.

[0027] In conclusion, this creation has indeed achieved a groundbreaking structural design and possesses improved new content, while also achieving industrial applicability and advancement. Furthermore, this creation has not been seen in any publication and possesses novelty, thus meeting the relevant provisions of the Patent Law. Therefore, we hereby file a new patent application in accordance with the law and earnestly request the Examining Committee of the Patent Office to grant legal patent rights. We are deeply grateful for your consideration.

[0028] The above description is merely one preferred embodiment of this invention and should not be construed as limiting the scope of this invention; that is, all equivalent changes and modifications made in accordance with the scope of this invention should still fall within the scope of this invention.
