Abstract
The utility model relates to an anti-theft plastic bottle cap with a seal-reinforced anti-seepage structure, which comprises an upper cap body (1), a lower cap body (2) and a connecting bridge (3), wherein a screw thread is arranged on the inside wall of the upper cap body (1). The anti-theft plastic bottle cap is characterized in that an annular seal-reinforced inner plug (4) is arranged on the inner side at the top part of the upper cap body (1), R-arc transition (6) is arranged at the joint of the top part and the inside wall of the upper cap body (1), and the annular seal-reinforced inner plug (4) and the R-arc transition (6) together form a double seal structure; the diameter of the annular seal-reinforced inner plug (4) ranges between the inside diameter and the outside diameter of the bottle mouth; an axial annular wedged lock catch (7) is arranged on the inside wall of the lower cap body (2) and is provided with an axis-section cone angle 'r'. The utility model has the benefits of reduced running torque for opening the cap, convenient uncapping, and strong leak tightness and leak prevention.
Description
Technical field
The utility model relates to a kind of plastic bottle closure, particularly relates to a kind of anti-theft plastic bottle lid with the density anti-leakage structure, is a kind of have plug and wedge surface snap close anti-theft plastic bottle lid in the density.Belong to plastic wrapping bottle cap technical field.
Background technology
At present, the plastic seal anti-theft bottle cap, especially for the seal cover cap of potable water, its quality increasing people pay close attention to.But the cushion seal cover cap of prior art because sealing inner plug and theft-prevention structure are unreasonable, therefore, easily produces seepage.End is got up, and mainly is following two aspect reasons:
The one, have only the individual layer seal ring, be difficult to effectively prevent seepage, sealing effectiveness is undesirable, and the sealing deforming zone of seal ring is big, seal ring frangibility, and the moment of torsion of uncapping is big needs with very energetically could twist-off closure, sometimes even block and do not open;
The 2nd, all by easily broken rib bonded assembly anti-theft ring, when opening bottle cap, lid is separated with anti-theft ring, anti-theft ring easily breaks away from from bottleneck, and anti-theft effect is poor.
The utility model content
The purpose of this utility model is in order to overcome the shortcoming of prior art, a kind of density antiseep plastic bottle closure that has to be provided.
The purpose of this utility model can reach by taking following technical scheme:
The anti-theft plastic bottle lid of band density anti-leakage structure comprises upper cover body, lower cover and connecting bridge, and the madial wall of upper cover body is provided with screw thread; Its constructional feature is: be provided with in the ring-type density in the inside top of upper cover body and fill in, be provided with the transition of R arc at the top of upper cover body and the junction of madial wall, form double sealing structure by plug and the transition of R arc in the ring-type density; The diameter of plug is between the internal diameter and external diameter of bottleneck in the described ring-type density; The madial wall of lower cover is provided with an axial ring-type wedge surface snap close, and this wedge surface snap close has shaft section cone angle r.
The purpose of this utility model can reach by taking following technical scheme:
A kind of embodiment of the present utility model is: plug forms angle a with the extended line of R arc transition in the ring-type density, clips external diameter in the bottleneck by the transition of R arc, forms closed contact.
A kind of embodiment of the present utility model is: the inside top in upper cover body is provided with gusseted on several well-distributeds, described go up that gusseted is filled in the ring-type density and the upper cover body madial wall between on the circumference.
A kind of embodiment of the present utility model is: the madial wall of lower cover is provided with gusseted under several well-distributeds, is used to add the support of wedge surface snap close.
The utlity model has following beneficial effect:
The utility model upper cover body adopts gusseted sealing inner plug and a angle antiseep, strengthens bottleneck and bottle cap close contact; The madial wall of lower cover is provided with all wedge surface snap closes and an A-frame, and this group wedge surface snap close has cone angle r and support makes the lower cover balance buckle bottleneck, plays antitheft effect.Therefore, have moment of torsion, uncap convenience, leak tightness and the strong beneficial effect of anti-leakage that reduction is uncapped.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment 1.
The specific embodiment
Specific embodiment 1:
Fig. 1 constitutes specific embodiment of the utility model 1.
With reference to Fig. 1, present embodiment comprises upper cover body 1, lower cover 2 and connecting bridge 3, and the madial wall of upper cover body 1 is provided with screw thread; Be provided with in the ring-type density in the inside top of upper cover body 1 and fill in 4, be provided with R arc transition 6, form double sealing structure by plug 4 and R arc transition 6 in the ring-type density at the top of upper cover body 1 and the junction of madial wall; The diameter of plug 4 is between the internal diameter and external diameter of bottleneck in the described ring-type density; The madial wall of lower cover 2 is provided with an axial ring-type wedge surface snap close 7, and this wedge surface snap close 7 has shaft section cone angle r.
In the present embodiment:
Described shaft section cone angle r can be 15 °.Described angle a is 15 °.Last gusseted 5, following gusseted 8 have 3 at least respectively, and be evenly distributed in the form of a ring.
The utility model can be reached the interior external diameter closed contact of bottleneck and play the antiseep effect.Owing to be provided with lower support 8 and wedge surface snap close 7 in lower cover 2 inside, its snap close 7 angled r fit fixing formation anti-theft ring, play antitheft effect.Connecting bridge 3 couples together upper cover body 1, lower cover 2, is evenly distributed, and when turning upper cover body 1 when the user uses, connecting bridge fractures, and upper cover body 1 is separated with lower cover 2, and lower cover 2 is stayed bottle mouth position.。
In fitting process; When bottle cap screwed in bottleneck, wedge surface snap close 7 entered recessed through the edge outside the bottleneck, because the shaft section of wedge surface snap close 7 has downward cone angle r, and wedge surface snap close 7 is in balance height, directly inserts and blocks, and is difficult to lower cover 3 therefrom be broken away from bottleneck again; When screwing the lid bottleneck, plug 4 contacts with the bottleneck seal area earlier in the ring-type density, and along with bottle cap is screwed, last gusseted 5 and R arc transition 6 closed contact bottleneck necks thoroughly seal bottleneck; When twist-off closure, the R arc transition 6 angle a of place discharge stress and reduce the uncork moment of torsion, thereby reduce the required strength of uncork; The fastening of locking in same cross section is in addition closed captive joint bridge 3 and is disconnected, so upper cover body is separated with lower cover is easier during uncork.
Other specific embodiments:
The characteristics of other specific embodiments are: described shaft section cone angle r can be 5 °, 10 °, 15 °, 20 °, 30 °, 35 °, 45 °, 50 ° or 60 °.Described angle a is 5 °, 10 °, 15 °, 20 °, 30 °, 35 °, 45 °, 50 ° or 60 °.Last gusseted 5, down gusseted 8 have 3,5,7,9,11,15,20,25,30,35 respectively, more than 40 or 40, evenly distributed in the form of a ring.All the other are with specific embodiment 1.
