Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

As shown in fig. 1 and 2, the utility model provides a high-sealing plastic bottle, which comprises a bottle body 1, a bottle mouth 3 is arranged on the upper portion of the bottle body 1, a bottle cap 2 is arranged on the bottle mouth 3, a convex ring 4 is arranged at the mouth of the bottle mouth 3, the convex ring 4 and the bottle mouth 3 are integrally formed, four clamping grooves 12 which are uniformly arranged are arranged on the convex ring 4, four inserting pieces 11 are arranged on the inner wall of the bottle cap 2, a gap is reserved between the inserting pieces 11 and the top of the bottle cap 2, so that the bottle can rotate after being inserted and closed, and the inserting pieces 11 are inserted into the clamping grooves 12 when the bottle is closed; a first sealing layer 5 is arranged at the lower part of the convex ring 4; a soft gasket 6 is arranged at the top in the bottle cap 2, and the convex ring 4 is pressed on the soft gasket 6; the soft gasket 6 is made of silica gel, and the soft gasket 6 is clamped in the annular positioning block 9 through the annular positioning block 9 arranged in the bottle cap 2, so that fixation is realized.

Bottle 1 with 3 junctions of bottleneck are equipped with protruding edge 7, be equipped with second sealing layer 8 on protruding edge 7, during the use, insert 11 with bottle lid 2 along draw-in groove 12 on the bulge loop 4 and insert the back, slightly rotate bottle lid 2 for insert 11 presses in bulge loop 4 lower part, can realize the fixed of bottle lid 2, it explains that, because bulge loop 4 lower part is provided with first sealing layer 5, can fill the clearance of insert 11 and bulge loop 4 lower part to cooperate the protruding edge 7 on the lower part second sealing layer 8, fill the clearance of insert 11 and lower part, greatly increased insert 11's stability after the interpolation closes, can not take place to become flexible even. The first sealing layer 5 and the second sealing layer 8 are silica gel layers.

And in order to further increase the sealing effect, the upper surface of the convex ring 4 is provided with a raised arc block, after the insertion, the arc block can be pressed on the soft gasket 6, the soft gasket 6 is a silica gel sheet, and the arc block can extrude and deform the soft gasket 6, so that the sealing effect is ensured.
