[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] See also Figure 1-Figure 5 The utility model provides a technical solution: a detachable structure for easy cleaning of laminated paper bowl, comprising a laminated paper tube 1 as a bowl wall and an outer pad 2 sleeved on the outside of the laminated paper tube 1, a bottom support assembly 3 is arranged at the bottom end of the laminated paper tube 1, a bowl cover assembly 4 is arranged at the top end of the laminated paper tube 1, and the edges at both ends of the laminated paper tube 1 are rolled outward to form a lower roll 11 and an upper roll 12 respectively.

[0034] The base assembly 3 includes a first clamping seat 32 fixedly mounted on the outer wall of the bottom end of the laminated paper tube 1 and clamped with the lower roll 11, a bottom cover 31 covering the bottom end of the laminated paper tube 1 and screwed to the first clamping seat 32, and a sealing ring 33 fixedly connected to the side of the bottom cover 31 close to the laminated paper tube 1 and in contact with the lower roll 11.

[0035] The bowl cover assembly 4 includes a second clamping seat 42 fixedly connected to the outer wall of the top end of the laminated paper tube 1 and clamped with the upper roll 12 , and a top cover 41 covering the top end of the laminated paper tube 1 and clamped with the second clamping seat 42 .

[0036] When in use, the bottom cover 31 serves as the bottom of the bowl and is screwed to the first holder 32 fixed on the outer wall of the bottom end of the coated paper tube 1, and a sealing ring 33 is provided to maintain a seal between the bottom cover 31 and the lower roll 11 to prevent water leakage and keep warm. When food is placed, the top cover 41 can be placed on the coated paper tube 1 and connected to the second holder 42 to further seal and keep warm. When cleaning is required, the top cover 41 is removed from the second holder 42, and the bottom cover 31 is unscrewed from the first holder 32, thereby being divided into three parts that can be cleaned independently, especially the coated paper tube 1 of the cylinder body has no dead corners for cleaning.

[0037] Furthermore, a plug protrusion 311 is provided at the central position of the top end of the bottom cover 31, and its side surface contacts the inner wall of the bottom end of the laminated paper tube 1. When the bottom cover 31 is closed toward the bottom end of the laminated paper tube 1, the plug protrusion 311 is inserted into the center of the bottom end of the laminated paper tube 1. Since the side surface of the plug protrusion 311 contacts the inner wall of the laminated paper tube 1, it helps with positioning, making it convenient to tighten the bottom cover 31 and the first clamping seat 32 later, while also improving the sealing performance and being able to support the material placed in the laminated paper tube 1.

[0038] Specifically, a first snap ring 312 is fixedly connected at a position near the edge of the top end of the bottom cover 31, a first slot 322 for accommodating the first snap ring 312 is provided on a side of the first socket 32 ​​close to the bottom cover 31, a second snap ring 411 is fixedly connected at a position near the edge of the bottom end of the top cover 41, and a second slot 422 for accommodating the second snap ring 411 is provided on the second socket 42; when the bottom cover 31 is covered on the coated paper tube 1, the first snap ring 312 will also be inserted into the first slot 322, to assist in positioning and further prevent air leakage to ensure sealing; when the top cover 41 is covered on the coated paper tube 1, the second snap ring 411 will also be inserted into the second slot 422, to help position the top cover 41 and prevent air leakage, thereby providing a heat preservation effect.

[0039] It should be noted that a first sealing groove 321 for accommodating the lower roll 11 is formed on the first clamping seat 32 close to the bottom cover 31, and a second sealing groove 421 for accommodating the upper roll 12 is formed on the second clamping seat 42; the first clamping seat 32 seals the paper body and the laminated film at the bottom end of the laminated paper tube 1 by clamping the lower roll 11 into the first sealing groove 321, and the second clamping seat 42 seals the paper body and the laminated film at the top end of the laminated paper tube 1 by clamping the upper roll 12 into the second sealing groove 421, thereby preventing the two ends of the laminated paper tube 1 from opening.

[0040] Furthermore, the inner wall at the bottom end of the top cover 41 has an inner edge 412 that contacts the bottom edge of the second card seat 42; when the top cover 41 is covered on the second card seat 42, the inner edge 412 may inwardly cover the bottom corner of the second card seat 42, thereby facilitating the top cover 41 to cover the top of the coated paper tube 1 tightly, which helps to seal.

[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
