Embodiment
As shown in Figures 3 to 6, the utility model includes outer cover 21, pad for sealing the plastic combination cover of hot fill product
Piece 22, outer cover 21 are threadedly coupled with the sealing of bottleneck 23.Seal closure 24 is additionally provided with bottleneck 23.The middle part of outer cover 21, which is provided with, to be stretched into
Collar flange 211 in bottleneck 23.Seal closure 24 is located at center section in the range of 23 bore of bottleneck along bottleneck 23 axially inwards
Depression forms concave part 241, and concave part 241 is in the cylinder of upper end opening, when not carrying out hot filling, the bottom surface of concave part 241
2412 be the sphere that is swelled axially upwards along bottleneck 23, there are gap between its peak and outer cover 21 when sphere swells, not because
The protuberance influences 21 shape of outer cover.After hot filling, under suction function, the bottom surface 2412 of concave part 241 is drawn to lower recess,
It is spaced at greater between outer cover 21, outer cover 21 will not be made completely because negative pressure deforms.Around concave part 241 on seal closure 24
Edge part 242 be embedded in the cavity between collar flange 211 and the inner wall 212 of outer cover 21, gasket 22 is located at edge part
242nd, it is pressed in the space that inner wall 212, the side 2411 of concave part 241 surround and by edge part 242 on bottleneck 23.To ensure
Between the side 2411 of leakproofness, gasket 22 and concave part 241 for interference fit, while for ensure air circulation, gasket 22 with
It is clearance fit between the inner wall 212 of outer cover 21.Sealing is realized preferably to coordinate with bottleneck 23, and gasket 22 is opened up along its circumferential direction
There is the groove 221 coincideing with 23 shape of bottleneck.In protruding parts insertion groove 221 on bottleneck 23.Edge part 242 is along its circumferential direction
The fin 2421 protruded towards outer cover 21 is provided with, which contacts with the inner roof wall of outer cover 21.Preferably, along edge part
242 spaced radial is provided with two circle fins 2421, in this way, between edge part 242 and outer cover 21, side 2411 and collar flange
Just the air flow passage of perforation is formd between 211 and between outer cover 21 and bottleneck 23, and (multiple small arrows represent sky in Fig. 6
Flow of air direction).To ensure compactedness, the stability of combined bottle cap entirety, ensure outer cover 21 and seal closure 24 when bottle cap is opened
Depart from bottleneck 23 at the same time, be circumferentially provided between the upper and lower every cloth along bottleneck 23 on the inner and outer wall of the side 2411 of concave part 241
Put and pothook A2413 that projected direction is opposite, the left side of collar flange 211 are provided with the grab projected radially outwardly along bottleneck 23
Portion B2111, pothook B2111 engage with the pothook A2413 being arranged on the inner wall of side 2411, and seal closure 24 is limited
Position.For the position of further setting-up piece 22, ensure its sealing performance, the pothook A2413 on the outer wall of side 2411
Positioned at the lower section of gasket 22, prevent gasket 22 from shifting.
The plastic combination cover of the utility model makes to pass through between seal closure 24 and outer cover 21 by increasing a seal closure 24 newly
Pothook A2413, pothook B2111 coordinate, and gasket 22 passes through the pothook A2413 on seal closure 24 on seal closure 24
Will not fall off gasket 22.In short, the plastic combination cover structure of the utility model is reliable and stable, outer cover 21 is turned round with 23 screw thread of bottleneck
Tightly, gasket 22 and bottleneck 23 fit closely, and ensure that the leakproofness of product.Meanwhile the suction function produced after hot filling is sealing
In lid 24, direction shown in block arrow is to lower recess along Fig. 6 under suction function for the bottom surface 2412 of seal closure 24, and outer cover 21 is then
From negative pressure influence, thus thoroughly solve the problems, such as consumer be difficult open bottle cap, and after hot filling bottle cap appearance not
It can deform.
Embodiment described above is only that the preferred embodiment of the utility model is described, not to this practicality
New scope is defined, and on the premise of the spirit of the design of the utility model is not departed from, those of ordinary skill in the art are to this
The various modifications and improvement that the technical solution of utility model is made, should all fall into the protection that the utility model claims book determines
In the range of.
