Abstract
Description
A mouth-held food packaging box and its lid Technical Field
[0001] This application relates to the field of food packaging box technology, specifically to a mouth-held food packaging box and its lid. Background Technology
[0002] Oral food packaging typically consists of a box body and a lid. Oral foods such as chewing gum and cigarettes are placed inside the food cavity of the box body. Opening the lid allows access to the oral food for consumption. The lid usually has a recycling chamber and a resealable cap to hold the consumed oral food, such as chewed gum residue or cigarette residue removed after a period of use, preventing indiscriminate disposal and environmental pollution.
[0003] Existing oral food packaging boxes use a flexible connector on one side of the lid to connect to the outer wall of the lid, enabling opening and closing. However, this type of oral food packaging box has poor sealing performance. Specifically, there are narrow gaps at the connection points between the lower ends of the flexible connector and the side walls of the lid. When the lid is opened, these gaps widen, connecting the inner cavity of the lid to the outside environment, and subsequently to the food cavity. Outside air can enter the inner cavity of the lid through the gaps on both sides of the flexible connector, and then into the food cavity, causing the oral food to become damp or accelerating its evaporation, thus affecting its taste. Summary of the Invention
[0004] To address the aforementioned deficiencies, the technical problem to be solved in this application is to provide a food packaging box for oral use and its lid, so as to solve the problems of poor sealing of the food cavity in the prior art, which makes the oral food susceptible to moisture or accelerates the volatilization of the oral food, thus affecting the taste.
[0005] Therefore, this application provides a lid for a food packaging box that can be held in the mouth, including a lid body. The top surface of the lid body is provided with a recycling cavity, and the recycling cavity is provided with an openable and closable cover. The cover is connected to the lid body through a flexible connecting part. The top surface of the annular wall of the recycling cavity is provided with a recessed annular step. The top surface of the annular wall is also provided with a first notch and a second notch that are arranged opposite to each other. The bottom surface of the cover is provided with an annular barrier, and the outer wall of the annular barrier is adapted to the inner wall surface of the annular step. The lower end of the flexible connecting part is provided on the top surface of the second notch.
[0006] Based on the above technical solutions, in this application, the lower end of the flexible connecting part is located on the top surface of the second notch, so that the interior of the lid and the box body forms a closed space. Opening or closing the lid will not cause the inner cavity of the lid to communicate with the outside, thereby improving the sealing of the food cavity of the box body and allowing the food inside to maintain a good taste for a long time. Furthermore, after the lid is closed, the annular barrier inserts into the annular step, improving the sealing of the recycling cavity.
[0007] In the above technical solution, preferably, the bottoms of the first notch and the second notch are located below the step surface of the annular step, and the height of the annular enclosure is greater than the depth of the first notch and the second notch. This embodiment facilitates opening the cover while maintaining the airtightness of the recycling chamber.
[0008] In the above technical solution, preferably, the top surface of the annular wall of the recovery chamber and the bottom edge of the cover adopt a conical mating structure. This conical mating structure further improves the sealing performance.
[0009] In the above technical solution, preferably, the outer wall of the annular enclosure is provided with multiple buckles, and the inner wall of the annular step is correspondingly provided with multiple hooks that cooperate with the buckles. In this embodiment, after the cover is closed, the hooks engage the buckles, which can prevent the cover from being opened unintentionally.
[0010] In the above technical solution, preferably, the buckle is wider in the middle than on both sides along its length, and the thickness at the root of the upper and lower surfaces is greater than that at the outer edge. This structural form of the buckle makes closing and opening the cover easier and more convenient.
[0011] In the above technical solution, preferably, a positioning post is provided on the bottom surface of the cover at the position corresponding to the box cover connection part, which cooperates with the second notch for positioning after the cover is closed.
[0012] In the above technical solution, preferably, the outer side of the lid connecting part is smoothly connected to the outer wall of the lid body.
[0013] This application also provides a mouth-held food packaging box, including a box body and a lid detachably disposed at the opening of the box body, the lid being the lid of the mouth-held food packaging box described above.
[0014] As can be seen from the above technical solution, the oral food packaging box and its lid provided in this application solve the problems of poor sealing of the food cavity in the prior art, which makes the oral food susceptible to moisture or accelerates the volatilization of the oral food, thus affecting the taste. Compared with the prior art, this application has the following beneficial effects:
[0015] The lid is connected to the box lid via a flexible connector, and its lower end is located on the top surface of the second notch, which creates a closed space inside the box lid. Opening or closing the lid will not cause the inner cavity of the box lid to communicate with the outside, thereby improving the sealing of the food cavity of the box body that cooperates with the lid, and allowing the food in the mouth inside the food cavity to maintain a good taste for a long time.

[0033] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0034] To provide a clearer explanation and description of the technical solutions and implementation methods of this application, several preferred specific embodiments for implementing the technical solutions of this application are described below.
[0035] It should be noted that the directional terms such as "inner" and "outer", "front" and "back" and "left" and "right" in this article are based on the product's usage status. Obviously, the use of these directional terms does not limit the scope of protection of this solution.
[0036] As shown in Figures 1 and 2, this application provides a food packaging box for oral use, including a box body 10 and a lid 20 detachably disposed at the opening of the box body 10. The box body 10 has a food cavity for storing oral food. This application employs an assembly method where the box body 10 and lid 20 are interlocked, facilitating the opening of the food cavity. Both the box body 10 and lid 20 are molded from plastic and are cylindrical in shape.
[0037] The lid 20 includes a lid body 21, with a recycling cavity 22 on the top surface of the lid body 21 for storing oral food after consumption. The recycling cavity 22 is provided with an openable and closable cap 30 for opening or closing the recycling cavity 22. The cap 30 is connected to the lid body 21 via a flexible connector 40. The lid body 21, the cap 30, and the flexible connector 40 are integrally formed.
[0038] As shown in Figure 3, a recessed annular step 23 is provided on the top surface of the annular wall of the recovery chamber 22. A first notch 24 and a second notch 25 are also provided on the top surface of the annular wall of the recovery chamber 22, and their depths extend below the step surface of the annular step 23, meaning the bottoms of the first notch 24 and the second notch 25 are below the step surface of the annular step 23. The lower end of the flexible connecting part 40 is connected to the top surface of the second notch 25.
[0039] An annular barrier 31 is provided on the bottom surface of the cover 30. The outer wall of the annular barrier 31 is adapted to the inner wall of the annular step 23. The height of the annular barrier 31 is greater than the depth of the first notch 24 and the second notch 25, which can prevent external dust and other debris from entering the recycling chamber 22. The first notch 24 is used to facilitate opening the cover 30.
[0040] The top surface of the annular wall of the recovery chamber 22 and the bottom edge of the cover 30 adopt a conical mating structure, which improves the sealing performance of the recovery chamber 22.
[0041] Referring again to Figures 3, 4, 5, 6, and 7, the flexible connection portion 40 includes a lid connection portion 41, a flexible portion 42, and a sealing connection portion 43. The lid connection portion 41 is narrower at the top and wider at the bottom, with its lower end fixed to the top surface of the second notch 25, and its thickness is less than the thickness of the second notch 25. The outer surface of the lid connection portion 41 is smoothly connected to the outer wall of the lid body 21. The flexible portion 42 is arc-shaped, and the end of the sealing connection portion 43 is connected to the conical surface of the edge of the sealing lid 30.
[0042] In this application, the lower end of the flexible connecting part 40 (the lower end of the lid connecting part 41) is fixed to the top surface of the second notch 25. As a result, the inner cavity of the lower part of the lid 20 connected to the box body 10 forms a closed cavity at the upper end and is completely isolated from the recycling cavity. Opening or closing the lid 30 will not cause the inner cavity of the lid 20 to communicate with the outside, thereby improving the sealing performance of the food cavity of the box body 10 and maintaining the taste of the food in the mouth in the food cavity for a long time.
[0043] The lid connection part 41 adopts a structure that is narrow at the top and wide at the bottom, and the base is thickened to improve the connection strength.
[0044] Please refer to Figures 3, 8, 9, 10, and 11. In this application, the outer wall of the annular enclosure 31 is provided with multiple buckles 32, which can be evenly distributed circumferentially. The inner wall of the annular step 23 is correspondingly provided with multiple hooks 26 that cooperate with the buckles 32. When the cover 30 is closed, the hooks 26 lock the buckles 32, which can prevent the cover 30 from being opened unintentionally.
[0045] In this application, the buckle 32 is wider in the middle than on both sides along its length, i.e., wider in the middle and narrower on both sides. The buckle 32 and the thickness of the root of the upper and lower surfaces are greater than the outer edge, i.e., thicker at the root and thinner at the outer edge. This design allows the cover 30 to be easily closed or opened by pressing down and lifting up.
[0046] In addition, multiple positioning posts 33 are provided on the bottom surface of the lid 20 at the position corresponding to the lid connection part 41, which cooperate with the second notch 25 to achieve the sealing and positioning of the lid.
[0047] Based on the above description of specific embodiments, the oral food packaging box and its lid provided in this application have the following advantages compared with the prior art:
[0048] First, the lid is connected to the box lid through a flexible connecting part. The lower end of the flexible connecting part is fixed to the top surface of the second notch, and no longer adopts a structure that is connected to the outer wall of the box lid. As a result, the inside of the box lid forms a closed structure. Opening or closing the lid will not cause the inner cavity of the box lid to communicate with the outside, which improves the sealing performance of the food cavity and can maintain the taste of the food in the mouth for a long time.
[0049] Second, the top surface of the annular wall of the recovery chamber and the bottom edge of the cover adopt a conical mating structure to improve the sealing performance of the recovery chamber.
[0050] Third, the lid connection adopts a structure that is narrower at the top and wider at the bottom, with thickened base to improve connection strength.
[0051] Fourth, multiple buckles are provided on the outer wall of the ring-shaped enclosure, and multiple hooks are provided on the inner wall of the ring-shaped steps. When the cover is closed, the hooks lock the buckles, which can prevent the cover from being opened unintentionally.
[0052] Finally, it should be noted that the terms "comprising," "including," or any other variations thereof as used herein are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising a…" does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
[0053] This application is not limited to the above-described preferred embodiments. Anyone should know that any structural changes made under the guidance of this application, and any technical solutions that are the same as or similar to those in this application, fall within the protection scope of this application.
