DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in combination with the implementation mode and the accompanying drawings. Here, the schematic implementation mode of the utility model and its description are used to explain the utility model, but are not used as a limitation of the utility model.

[0026] See also Figure 1-Figure 8 The embodiment of the utility model provides a flange barrel for nesting, comprising a barrel body 1 and a barrel cover 2 which is detachably nested at the top of the barrel body 1 and is used to package the barrel body 1. The barrel body 1 is in the shape of an inverted truncated cone with a thick upper part and a thin lower part.

[0027] In practice, the flange barrel can be made of high-strength plastic material as a whole; the barrel body 1 includes a barrel neck 3, a barrel body 4 and a barrel bottom 5, the barrel neck 3 is in a straight cylindrical shape, the barrel body 4 is in an inverted frustum shape connected to the bottom of the barrel neck 3, and the barrel bottom 5 is in a circular plate shape and encapsulated at the bottom of the barrel body 4.

[0028] An arc-shaped transition section 6 is provided between the barrel neck 3 and the barrel body 4; the three-section design structure facilitates the nesting and separation of the barrel bodies 1. The barrel neck 3, the arc-shaped transition section 6, the barrel body 4 and the barrel bottom 5 can be an integrally formed structure.

[0029] The barrel bottom 5 is provided with a stabilizing groove 7 protruding toward the inner side of the barrel body, which can strengthen the load-bearing function of the barrel body 1. In order to further improve the firmness of the barrel bottom 5, the barrel bottom 5 can be a two-section structure, specifically including an outer ring groove section connected to the bottom of the barrel body 1 and an inner circular plate section connected to the outer ring groove section.

[0030] The stabilizing groove 7 is arranged along the diameter direction of the barrel bottom 5 .

[0031] The stabilizing groove 7 includes an inverted V-shaped groove and arc grooves connected to both ends of the inverted V-shaped groove.

[0032] A fixing groove 8 is provided at the top of the barrel neck 3 along its circumference, and the fixing groove 8 protrudes toward the inner side of the barrel body 1 to improve the nesting firmness between the barrel neck 3 and the barrel cover 2.

[0033] A bottom wing edge 9 is disposed on the outer side of the barrel neck 3 and below the fixing groove 8 , and the bottom wing edge 9 is orthogonal to the axial direction of the barrel neck 3 .

[0034] The barrel cover 2 includes a circular plate-shaped cover body 10, and a snap-fitting portion 11 is provided on the outer edge of the cover body 10 and is adapted to the top of the barrel body 1 to achieve a sealed package with the barrel body 1. A through hole 12 is opened on the cover body 10, and the through hole 12 can be used as an exhaust hole to cooperate with existing vacuum pumping and inflation equipment to meet the needs of containing specific products, and at the same time balance the pressure difference inside and outside the barrel to prevent serious deformation. After the filling is completed and the needs are met, the through hole can be sealed with a suitable rubber plug.

[0035] The clamping part 11 is in an inverted V shape, and the outer edge is lower than the plane where the cover body 10 is located; the outer edge of the clamping part 11 is provided with a top wing edge 13, the plane where the top wing edge 13 is located is parallel to the plane where the body is located, and the top wing edge 13 is adapted to the bottom wing edge 9. The wing edge setting height can be changed as needed, so that when the barrel body 1 and the barrel cover 2 are packaged, the top wing edge 13 and the bottom wing edge 9 have a certain gap or are close to each other. When there is a gap, the barrel cover can be easily disassembled, and when they are close to each other, the packaging effect can be improved. At this time, a sealing tape can also be used to further improve the sealing. The inverted V-shaped size of the clamping part 11 is adapted to the wall thickness of the barrel neck 3 for nesting on the barrel neck wall and ensuring sealing. In addition, a convex strip 14 can be provided on the outside of the clamping part 11 to facilitate the application of force when the cover body is disassembled, and a sealing gasket can be provided on the inside of the clamping part 11 to further improve the sealing performance.
