Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, the utility model discloses a plastic container, which comprises a barrel body 1 and a barrel cover 2.

Referring to fig. 1 and 2, the barrel 1 is provided with a sealing assembly 3 at the bung, and the sealing assembly 3 includes a sealing ring 31 having an inner diameter smaller than the bung, and a telescopic portion 32 provided at the bung of the sealing ring 31. The lower terminal surface of sealing ring 31 is provided with bulge loop 311, and confession bulge loop 311 male seal groove 11 has been seted up along circumference to bung hole up end, and for making things convenient for personnel to put into the seal groove 11 with bulge loop 311, the inside wall of bulge loop 311 sets up to the spigot surface 312 that has the cambered surface. In order to improve the sealing effect after the protruding ring 311 abuts against the sealing groove 11, referring to fig. 3, a gasket 111 abutting against the protruding ring 311 is provided at the bottom of the sealing groove 11. The expansion part 32 comprises a bellows 321 connected to the opening of the sealing ring 31, and a moving plate 322 connected to the other end of the bellows 321. The two ends of the corrugated expansion pipe 321 are respectively connected with the sealing ring 31 and the moving plate 322 in a sealing manner, and the corrugated expansion pipe 321 is arranged in a folding manner along the axial direction of the barrel body 1, so that the expansion can be performed along the axial direction of the barrel body 1. The moving plate 322 is provided with a handle on its upper surface.

Referring to fig. 4 and 5, the outer diameter of the sealing ring 31 is the same as or slightly smaller than the inner diameter of the tub cover 2.

Referring to fig. 1 and 6, a plurality of limiting grooves 12 are uniformly formed in the upper end surface of the bung along the circumferential direction of the bung outside the sealing groove 11, and preferably, three limiting grooves 12 are formed in the embodiment. The bottom of each limit groove 12 is communicated with a clamping groove 13. The bottom of the outer ring of the sealing ring 31 is provided with a limiting block 51 for sliding insertion into the limiting groove 12, the bottom of the limiting block 51 is provided with a blocking block 52 for insertion into the blocking groove 13 when rotating, and the notch of the limiting groove 12 can be inserted by the blocking block 52. To facilitate the insertion of the stopper 51 into the stopper groove 12, referring to fig. 3, the groove wall of the stopper groove 12 has a guide surface 121 with a curved surface at the notch. In order to ensure that the locking block 52 is matched with the locking groove 13, referring to fig. 2, the side walls of the locking block 52 and the locking groove 13 are both arc-shaped surfaces 53, and the arc-shaped surfaces 53 are circumferentially arranged for matching with the bung.

The implementation principle of the embodiment is as follows: after a person takes out a part of the articles in the barrel, the person firstly puts the sealing ring 31 at the opening of the barrel, and presses the moving plate 322 downwards by the handle to a position close to the upper surface of the articles in the barrel, so that the corrugated expansion pipe 321 will move downwards along with the moving plate 322 to unfold. Subsequently, the person puts the stopper 51 into the stopper groove 12, horizontally rotates the sealing ring 31, rotates the stopper 52 into the stopper groove 13, and simultaneously clips the convex ring 311 of the sealing ring 31 downward into the sealing groove 11. When the person screws the barrel cover 2, the bottom surface of the barrel cover 2 abuts against the upper surface of the sealing ring 31, so that the convex ring 311 abuts against the sealing gasket 111 to realize a sealing effect, and at the moment, the object stored in the barrel body 1 can be prevented from contacting with a large amount of air.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
