The utility model is characterized in that the junction of the top and the inner wall of the upper basal body 1 forms a convex R border arc side 6 enveloping a bottle mouth, and the chamfer of the convex R border arc side 6 is gamma, which ranges from zero DEG to 30 DEG. The inner wall of the top of the upper basal body 1 is provided with a sealing gasket 5, and the sealing gasket 5 corresponding to the solid part of the bottle mouth is provided with a buildup area 1. The cross section of the antitheft grommet 4 is in a rabbet shape and can bend up beta angle, which ranges from 60 DEG to 90 DEG. An attenuated declivity is arranged on the outer margin of the lower basal body 2 and above the antitheft grommet 4, and the separation angle of the declivity and the normal plane is alpha, which ranges from zero DEG and 30 DEG. The utility model has good sealing property and antitheft property and is comprehensively suitable for various oxygen-containing or non-oxygen drink bottles.
Description
The utility model relates to a kind of plastic bottle closure, and particularly a kind of novel anti-theft plastic bottle closure belongs to sealing, the technical field of burglary prevention of plastic bottle closure.
The plastic bottle closure of band EVA, the PE of prior art or the pre-gasket of other village's matter, its sealing property is better than the plastic bottle closure of the direct injection moulding Gask-O-Seal of caping, but still has following shortcoming: 1. packing seal edge pressure is not firm, breaks away from lid easily; 2. the Safety ring locks buckle structure is unreasonable, and all much larger than 1, theftproof performance is undesirable to make the radian value (being called for short the LB value) of opening bottle cap hourglass angle (LEAK), the angle of rupture (BREAK).
The purpose of this utility model is in order to overcome the shortcoming of prior art, a kind of novel anti-theft plastic bottle closure to be provided, and this novel anti-theft plastic bottle closure has following characteristics:
The purpose of this utility model can reach by taking following measure: a kind of novel anti-theft plastic bottle closure, comprise matrix, lower substrate and be connected the connecting bridge of matrix, lower substrate, last matrix is made up of top and sidewall and madial wall is provided with screw thread, the inwall of lower substrate is provided with the anti-theft column lock clasp, its constructional feature is: the top of going up matrix forms the protruding R edge cambered surface of containing bottleneck with the junction of madial wall, the corner cut of this protruding R edge cambered surface is γ, and 0 °≤γ≤30 °; The inside top of last matrix is provided with packing seal, the sealing pad extends certain-length downwards along protruding R edge cambered surface, and corresponding to the entity part of bottleneck, packing seal is provided with buildup area L; But the cross-sectional plane of anti-theft column lock clasp is subtriangular tenon shape K/UP β angle, the antitheft groove of bottleneck outer rim is formed actv. interference district, and 60 °≤β≤90 °; The outer rim of lower substrate is provided with the attenuate dip plane on being positioned at the anti-theft column lock clasp, and the angle of this attenuate dip plane and vertical surface is α, and 0 °≤α≤30 °.
Compared with prior art, the utlity model has following outstanding advantage:
1. for the sealing property of enhanced leaktightness pad, in use connecting bridge is easily broken, in the utility model, it is molded that packing seal adopts elastomeric material to drip, connecting bridge by the lid injection moulding after excision forming.Because the top of last matrix and the junction of madial wall have the protruding R edge cambered surface that contains bottleneck, the corner cut of this protruding R edge cambered surface is γ, so packing seal can not come off from the top of matrix; Owing to the entity part corresponding to bottleneck, packing seal is provided with buildup area, so packing seal and bottleneck closed contact simultaneously, and theftproof performance is good.
2. but the cross-sectional plane of anti-theft column lock clasp is tenon shape K/UP β angle, the other antitheft groove of bottleneck outer rim is formed actv. interference district, the outer rim of lower substrate is provided with the attenuate dip plane on being positioned at the anti-theft column lock clasp, the angle of this dip plane and vertical surface is α, and 0 °≤α≤30 °, therefore lower substrate high resilience, theftproof performance is good.
Below in conjunction with accompanying drawing the utility model is described in detail:
Fig. 1 is the constructional drawing that partly cuts open of the present utility model.
Fig. 2 is the A place partial schematic diagram of Fig. 1.
Fig. 1, Fig. 2 constitute embodiment 1 of the present utility model.As can be seen from Figure 1, present embodiment comprises matrix 1, lower substrate 2 and is connected the connecting bridge 3 of matrix 1, lower substrate 2, last matrix 1 is made up of top and sidewall and madial wall is provided with screw thread, the inwall of lower substrate 2 is provided with anti-theft column lock clasp 4, the top of last matrix 1 and the junction of madial wall form the protruding R edge cambered surface 6 that contains bottleneck, the corner cut of this protruding R edge cambered surface 6 is γ, wherein γ=5 °; The inside top of last matrix 1 is provided with packing seal 5, sealing pad 5 extend downward R edge cambered surface along protruding R edge cambered surface 6 terminal point, entity part corresponding to bottleneck, packing seal 5 is provided with buildup area l, buildup area 1 is slightly larger than the poor of bottleneck external diameter, internal diameter, and packing seal 5 adopts elastomeric material to drip molded; But the cross-sectional plane of anti-theft column lock clasp 4 is subtriangular tenon shape K/UP β angle, the antitheft groove of bottleneck outer rim is formed actv. interference district, and β=60 °; The outside of lower substrate 2 is provided with the attenuate dip plane on being positioned at anti-theft column lock clasp 4, and the angle of this dip plane and vertical surface is α, and α=5 °; Connecting bridge 3 by the lid injection moulding after excision forming.
As can be seen from Figure 1, because the top of last matrix 1 and the junction of madial wall form protruding R edge cambered surface 6, the slip-off preventing γ angle of containing bottleneck, have protruding R edge cambered surface 6, the slip-off preventing γ angle of containing bottleneck for packing seal 5, so packing seal 5 can not come off from the top of last matrix 1 yet; Simultaneously because corresponding to the external diameter of bottleneck, packing seal 5 is provided with buildup area 1, and buildup area 1 is slightly larger than the poor of bottleneck external diameter, internal diameter, therefore packing seal 5 and bottle closed contact when bottle cap is screwed down, theftproof performance is good.As can be seen from Figure 2, the outside of lower substrate 2 is provided with the attenuate inclined angle alpha on being positioned at anti-theft column lock clasp 4, so lower substrate 2 has sufficient elasticity, and convenient and theftproof snap close ring 4 enters the antitheft groove of bottleneck outer rim; The cross-sectional plane of anti-theft column lock clasp 4 is subtriangular tenon shape, when bottle cap screws in bottleneck, anti-theft column lock clasp 4 K/UP β angles under the effect of bottleneck outward flange, the face 8 of anti-theft column lock clasp 4 is positioned on the M-M plane, this K/UP β angle disappears after anti-theft column lock clasp 4 strides across the bottleneck outward flange, anti-theft column lock clasp 4 enters the antitheft groove of bottleneck outer rim, because anti-theft column lock clasp 4 high resiliences, therefore, the antitheft groove that anti-theft column lock clasp 4 enters the bottleneck outer rim is positioned on the N-N plane, antitheft groove to the bottleneck outer rim forms actv. interference district, three faces 7 of anti-theft column lock clasp 4,8,9 all fully contact with the antitheft groove of bottleneck, the M-M face that presses bottleneck, the N-N face, therefore that lid 2 disengaging bottlenecks are just quite difficult.
Embodiment 2 of the present utility model is: γ=10 °, β=70 °, α=15 °, all the other are with embodiment 1.
Embodiment 3 of the present utility model is: γ=30 °, β=80 °, α=20 °, all the other are with embodiment 1.
Embodiment 4 of the present utility model is: γ=20 °, β=90 °, α=30 °, all the other are with embodiment 1.
