Description

Technical Field

[0001] This utility model relates to the field of food packaging technology, specifically to a multi-sealed packaging bowl. Background Technology

[0002] Packaging bowls are containers widely used in the food, beverage, and daily chemical industries, primarily for holding and transporting various products. Common materials include plastics, paper products, metals, and glass, offering advantages such as lightweight, durability, and environmental friendliness. The design of packaging bowls not only needs to meet basic functions of holding and transporting products but also requires excellent sealing to ensure that the contents are not contaminated or leaked during transportation and storage. Sealing performance is particularly important when holding liquids or items requiring high levels of airtightness.

[0003] Currently, packaged bowls on the market typically consist of two parts: a bowl body and a lid. The lid is usually fastened to the inside of the bowl body. To improve the sealing performance, the opening at the top of the bowl body is usually designed as a stepped structure. This structure achieves initial sealing through a tight fit between the lid and the bowl body. However, this design has certain limitations in practical use. First, the sealing effect of a single-layer stepped structure is limited, especially when containing liquids or items requiring high sealing performance, making it difficult to completely prevent liquid leakage or the intrusion of external contaminants. Second, since the connection between the lid and the bowl body relies solely on the pressure of the single-layer stepped structure, its sealing performance is easily affected by external impacts or temperature changes, leading to seal failure. For example, during transportation, the lid may loosen due to vibration or compression, causing liquid leakage or damage to the contents. Furthermore, the single-layer stepped structure design may further reduce its sealing performance after long-term use due to material wear or deformation. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a multi-layer sealing packaging bowl, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0008] Furthermore, a bowl-shaped rim ring is fixed to the top surface of the first side rim ring. The outer diameter of the bowl-shaped rim ring is larger than the outer diameter of the first side rim ring. The top surface of the bowl-shaped rim ring is fitted with the stepped structure between the cover rim ring and the sealing ring.

[0009] Furthermore, the bowl rim component also includes a snap-fit ​​block, which is fixed to the inner wall of the first side rim ring. Four snap-fit ​​blocks are fixed in a cross-shaped arrangement.

[0010] Furthermore, the outer wall of the sealing ring is provided with a slot, and four snap-fit ​​blocks are snapped into the slot to secure the sealing ring to the inside of the first side ring.

[0011] Furthermore, a slanted guide ring is fixed to the bottom surface of the sealing ring. The slanted guide ring has an inclined cross-section and its bottom surface is attached to the second side ring stepped plane.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Example 1

[0026] To address the technical problems in the background section, the following multi-layered sealing packaging bowl is provided:

[0027] Combination Figures 1-6 As shown, the present invention provides a multi-sealed packaging bowl, including a bowl body 1 and a lid body 3. The bowl body 1 is a frustum-shaped structure that is wider at the top and narrower at the bottom. A bowl rim component 2 is provided on the top surface of the opening of the bowl body 1. The bowl rim component 2 is a two-stage stepped structure. The lid body 3 is a frustum-shaped structure that is narrower at the top and wider at the bottom. A lid rim ring 31 is provided on the bottom surface of the opening of the lid body 3. A sealing ring 32 is fixed on the bottom surface of the lid rim ring 31. The diameter of the lid rim ring 31 is larger than the diameter of the sealing ring 32. The lid rim ring 31 and the sealing ring 32 are in a stepped structure. The sealing ring 32 is inserted into the bowl rim component 2. A push block 4 is fixed on the outer wall of the lid body 3.

[0028] The above structure achieves the following effect: by setting a bowl rim component 2 with a two-stage stepped structure on the bowl body 1, the sealing ring 32 on the cover body 3 can be inserted into the inside of the bowl rim component 2 to tightly fit and seal the stepped structure of the bowl rim component 2, sealing the bending position of the stepped structure, thereby improving the overall sealing performance of the packaging bowl.

[0029] In this embodiment, the bowl rim component 2 includes a first side rim ring 21 and a second side rim ring 22. The first side rim ring 21 is fixed to the top surface of the second side rim ring 22, and the second side rim ring 22 is fixed to the top surface of the bowl body 1. Both the first side rim ring 21 and the second side rim ring 22 are stepped structures, and the diameter of the first side rim ring 21 is larger than the top surface of the second side rim ring 22. By setting the first side rim ring 21 and the second side rim ring 22 with stepped structures and fixing them to form a two-stage stepped structure, the stability of the sealing structure is ensured.

[0030] In this embodiment, a bowl-shaped rim ring 211 is fixed to the top surface of the first side rim ring 21. The outer diameter of the bowl-shaped rim ring 211 is larger than the outer diameter of the first side rim ring 21. The top surface of the bowl-shaped rim ring 211 is fitted with the stepped structure between the cover rim ring 31 and the sealing ring 32. By setting the bowl-shaped rim ring 211, the fitting area of ​​the stepped structure between the bowl mouth of the bowl body 1 and the cover rim ring 31 and the sealing ring 32 is increased, which further improves the sealing performance of the packaging bowl and enhances the stability of the seal.

[0031] Example 2

[0032] like Figures 1-6 As shown, based on the above embodiments, this embodiment further provides the following:

[0033] The bowl rim component 2 also includes a snap-fit ​​block 23, which is fixed to the inner wall of the first side edge ring 21. Four snap-fit ​​blocks 23 are fixed in a cross shape. By snapping the first side edge ring 21 onto the sealing ring 32, the stability of the connection between the sealing ring 32 and the first side edge ring 21 is improved.

[0034] In this embodiment, the outer wall of the sealing ring 32 is provided with a slot 321, and four snap-fit ​​blocks 23 are snapped into the slot 321 to snap the sealing ring 32 into the first side edge ring 21. By setting the slot 321 structure, the snap-fit ​​blocks 23 are snapped into the slot 321, which further improves the stability of the connection between the sealing ring 32 and the first side edge ring 21.

[0035] In this embodiment, a slanted guide ring 322 is fixed to the bottom surface of the sealing ring 32. The slanted guide ring 322 has an inclined cross-section and its bottom surface is attached to the stepped plane of the second side ring 22. By attaching the slanted guide ring 322 to the stepped surface of the second side ring 22, not only is the stability of the connection between the sealing ring 32 and the second side ring 22 ensured, but the sealing performance is further improved.

[0036] Working principle and usage process of this utility model:

[0037] First press Figures 1-6 Place the item inside the bowl 1, grip it firmly onto the two push blocks 4 with your fingers, and then close the bowl lid tightly onto the bowl 1. This allows the inclined guide ring 322 to first be inserted into the first side edge ring 21 using its inclined surface as a guide. Then, continue pushing the bowl lid to fully insert and press the sealing ring 32 into the first side edge ring 21. This ensures that the bottom surface of the inclined guide ring 322 is in contact with the stepped plane of the first side edge ring 21, and the top surface of the bowl rim ring 211 is in contact with the stepped surface formed between the lid rim ring 31 and the sealing ring 32. At this point, the four latching blocks 23 are fully engaged into the slots 321, ensuring a fully sealed connection between the lid 3 and the bowl 1, thus guaranteeing the safety and stability of the placed item.
