In addition, the present invention further provides a kind of pilfer proof closure made from synthetic resin, it comprises a lid and a stopper, described lid has a roof and a lateral margin that hangs down from roof, make a lid thread segment that can be screwed on the container finish outer surface thread segment in the interior perimeter surface of ring-type lateral margin, and a pilfer band is linked to be integral body with the lateral margin base in flakes by a plurality of; Described stopper oral area of airtight container reliably still when lid is loosening; It is characterized by, before each described even piece fracture, the air-tightness of container finish is maintained by stopper; A stopper lead ring can lift stopper from container finish; Stopper also has an interior hermetic unit, and it can be inserted among the inside face of container finish reliably; Stopper also has the air reservoir of a surface formation thereon in addition.Described air reservoir also can form on a roof lower surface relative with the described upper surface of stopper.
According to the present invention, the described stopper lead ring of employing has an annular protrusion that forms on the perimeter surface in described lateral margin.When lid is screwed onto on the container, described convex annular role is: be fixed on the oral area that under the state of cap topwall lower surface one side lid is installed to container at stopper, therefore, rotate lid along the closed with covers direction, the lid thread segment is slided along the container finish thread segment, just can make the oral area of container obtain firm sealing by means of stopper, described stopper just remains between roof lower surface and the annular protrusion.In addition, the function of described annular protrusion also has when lid is loosening, although the lid thread segment slides along the container threads section, but the air-tightness that before rupturing in flakes, can keep container finish at least by means of stopper, and when rupturing in flakes, annular protrusion can lift stopper from container finish.Annular protrusion can be made integral body with lid, and it and leaves the distance D of an appointment with the lower surface of roof 1 between lid thread segment 5 and roof 1; Annular protrusion also can separate making with lid, and placement location is the same.That is to say,, before rupturing in flakes, can make stopper keep the air-tightness of container, and when rupturing in flakes, can lift stopper cancellation sealing as the annular protrusion of stopper lead ring.
In addition, in order to guarantee described distance to a declared goal D, also can assign to replace described annular protrusion with the topmost of the conventional thread segment of lid.
According to this stopper of the present invention can for example paper and synthetic resin be made by some common used materials.
And this stopper uses in following situation:
(1). when container is full of a kind of liquid of at high temperature heat-treating, or after full of liquid, stand high-temperature heat treatment, and then cool to room temperature, consequently the pressure of sealed container interior reduces;
(2). the pressure that is full of the tight seal internal tank of article is higher than the pressure of this external container;
(3). the pressure of tight seal internal tank equals the pressure of this external container.
According to the present invention, (A) at first, under container is held in situation as decompression state mentioned above, when lid is loosening, in order to prevent that at least stopper from rotating with lid, on stopper upper surface or roof lower surface, make air reservoir with respect to the stopper upper surface.Described air reservoir comprises a plurality of groove circular depressions and the groove between shim, and described groove is along the circumferencial direction H of this shim on shim.Form with one heart mutually, described circular depressions is centered on by each shim, and described groove is to form on the upper surface of stopper.During closed with covers, though air layer can form between roof lower surface and stopper naturally, according to the present invention, be preferably in make on the thread segment of container finish a plurality of, make the groove that can go into recess and shim by the concentrated flow between the shim, so that between the upper surface of the lower surface of roof and stopper, determining to form an air layer during the closed with covers by the air of this groove.In addition, the groove that forms on the also available lid thread segment replaces the groove that forms on the container threads section, gives air layer air supply with it.(B) secondly, be in as under (2) described pressurized state situation above at container, when lid is loosening, rotate with lid in order to prevent stopper, adopt a kind of stopper with an interior hermetic unit, described interior hermetic unit can closely insert among the inside face of vessel port.On the lower surface of described stopper, make the interior hermetic unit of an annular.In order to improve air-tightness, the insertion length L of described interior hermetic unit is preferably pressed selected works and is selected.

With reference to the accompanying drawings, introduce a most preferred embodiment of synthetic resin anti-theft lid of the present invention.But the present invention is not limited by this embodiment.
At first referring to Fig. 1 to 3, the pilfer proof closure that synthetic resin is made (hereinafter referred is lid) C comprises a lid 6 and a stopper 9, described lid 6 has flat-top wall 1 and ring-type lateral margin 2 that hangs down from roof 1 of a circle, on the outer surface 3a of container bottle oral area 3, make thread segment 4, thread segment 5 at the lid of making on the interior perimeter surface 2a of ring-type lateral margin 26 just is screwed on this thread segment 4, anti-theft circle (hereinafter be referred to as PP circle) 87,7 is linked to be integral body with described lid 6 in flakes by a plurality of; And described stopper 9 is positioned at the inside of lid 6, and it can closely seal container finish 3 during described lid is closed; Make a lead ring 10 between lid thread segment 5 in described lateral margin on the perimeter surface 2a and the roof 1, so that before 7 fractures in flakes, can keep the air-tightness of container finishs 3 by described stopper 9; When twisting the lid off, as long as described 7 fractures in flakes, lead ring 10 just can lift the stopper 9 on the container finish 3; Hermetic unit 11 can insert among the inside face 3b of container finish 3 stopper 9 securely in the annular, also has an air reservoir 12 that on stopper 9 upper surface 9a, forms, during lid was closed, air a can flow into air reservoir 12 from the described outer surface 3a of container finish 3.
Again simultaneously referring to Fig. 2, the described air reservoir of making on stopper 9 upper surfaces 12 comprises a plurality of groove 13, a circular depressions 15 and an a plurality of groove N, described groove 13 is that the circumferencial direction (the H direction among the figure) along this shim is made separately with one heart on a plurality of shims 14, described recess 15 is centered on by each shim 14, and described groove N is between shim 14.During lid is closed, air a flows through a plurality of groove M that make earlier on the container threads section 4,4 of container finish outer surface 3a, flow into a plurality of described groove 13 of described recess 15 and shim 14 again through groove N between shim 14, thereby between the upper surface 9a of the lower surface 1a of roof 1 and stopper 9, form an air layer S.
In addition, on the lower surface of stopper 9, make described in hermetic unit 11 be intended to improve air-tightness and prevent that stopper from rotating together in company with lid, and it (is L 〉=D) that the length L of inserting the interior hermetic unit 11 of container bottle a inside face is configured to be equal to or greater than length D from roof 1 lower surface to stopper lead ring 10 upper ends.
And stopper lead ring 10 has an annular protrusion, and this annular protrusion is made integral body along the interior perimeter surface 2a of lateral margin 2 with lid 6.As mentioned above, to leave the distance of roof 1 lower surface be D to annular protrusion 10.In addition, lid C by themoplasticity synthetic resin for example polyethylene and polypropylene make, the method for employing can be injection moulding or other method that is suitable for.In order to support described PP circle 8, a plurality of intervals of hanging down from the base 20 of lateral margin 2 suitable in flakes 7.Described PP encloses inside reflexed, thereby has suitable elastomeric protruding 21 a plurality of of its compartment of terrain, lower end formation.Make a shoulder 22 around container finish 3, when lid C correctly is installed on the container finish 3, PP circle 8 and container finish 3 mechanical engagement, this moment described protruding 21, the following junction surface 22a with shoulder 22 idle sides engaged.In addition, on the outer surface 2b of lateral margin 2, also make many suitable serrations.Be noted that container threads section 4 and lid thread segment 5 are in fact respectively continuous in a cluster, in Fig. 1, they marked many times just for convenience of explaining the action of uncapping.
Because this most preferred embodiment has said structure, be used to closely seal at this synthetic resin pilfer proof closure C under the situation (A) of the container that the decompression state article are housed, cover 6 and apply that a turning effort is feasible covers 6 when closed state shown in Figure 4 unclamps state shown in Figure 5 when giving along the direction of uncapping, not only because air a is flow to the upper surface 9a (seeing Fig. 2 for details) of stopper 9 by the outer surface 3a of container finish 3, between the upper surface 9a of the lower surface 1a of roof 1 and stopper 9, form an air layer S, consequently form air reservoir air chamber 12 in other words, and stopper 9 also has hermetic unit 11 in the annular among the inside face 3b that can insert container finish 3 reliably, therefore, even proceed to the degree of not removing lid fully owing to mischief and so on reason makes the action of uncapping, stopper 9 still can be avoided rotating together in company with lid really, thereby at least up in flakes 7 owing to elongation rupture and can be kept before the air-tightness of container.And, at least in flakes 7 determine fracture after, keep above-mentioned vacuum-packed stopper 9 under the effect of stopper lead ring 10, to rise together in company with lid 6, thus the mouth cylindrical part of openable container 3.
As mentioned above, in this most preferred embodiment, when lid is removed, before a plurality of 7 fractures in flakes, stopper 9 can both keep the air-tightness of container finish 3, so that, even if it is loosening that this lid has slightly, as long as 7 do not rupture in flakes, stopper 9 can not rise in company with lid 6 together yet.
In addition, even replaced situation (A) in situation (B), that is be used to the situation of container that the tight seal splendid attire is in the article of pressurized state at the synthetic resin pilfer proof closure and replaced the synthetic resin pilfer proof closure to be used for the tight seal splendid attire when being in the situation of container of article of decompression state, use a kind of structure or another kind of structure that is similar to above-mentioned most preferred embodiment still can present the effect similar to above-mentioned most preferred embodiment, stopper comprises the interior hermetic unit that can closely insert the container finish inside face and have designated length in this another kind structure.
Yet, although in above-mentioned most preferred embodiment, use so-called one chip PP lid, wherein lid is made integral body by in flakes a plurality of or similar component and PP circle, the present invention also can adopt so-called two-piece type PP lid, wherein lid is with to separate with PP and is made, and just is linked to be integral body before being about to be installed to container finish.
Have again, in Fig. 6,7, expressed two kinds of distortion of air reservoir.Referring to Fig. 6, shim 14 has a plurality of radially grooves 13 of (the R direction among the figure) respectively, and makes the circular depressions 15 that is centered on by each shim 14 on the upper surface of stopper earlier.And in Fig. 7, the circular depressions of making on the stopper upper surface 15 is centered on respectively by a plurality of shims 14 with rough surface.
Obviously, also can make and be similar to the air chamber in other words of the air reservoir shown in Fig. 2,6 and 7 at the roof lower surface.
In addition, shim not only can provide aforesaid groove along concentric direction (graphic H direction), along the radially groove or the rough surface of (graphic R direction), and can make the checkerboard groove, also is so-called annular knurl groove.In brief, just enough as long as can prevent that stopper from rotating together in company with lid.
As mentioned above, making pilfer proof closure at this synthetic resin is used for closely sealing under the situation that the container that is in the decompression state article is housed when being full of container with the liquid of just at high temperature heat-treating, perhaps container is subjected to high-temperature heat treatment after being full of this liquid, then again during cool to room temperature, the pressure of internal tank reduces, produce vacuum, therefore only otherwise produce the power that rises stopper, just can continue the oral area of airtight container securely with stopper.And, even if do not remove the degree of lid fully owing to reasons such as mischief get loose lid, the air reservoir that provides by means of stopper upper surface or the top cover lower surface relative with the stopper upper surface, can between roof lower surface and stopper upper surface, form air layer, thereby can prevent that at least stopper from rotating in company with lid, thereby before rupturing owing to elongation in flakes, keep the air-tightness of internal tank at least.And, be at least after determining fracture in flakes, keep above-mentioned vacuum-packed stopper under the effect of stopper lead ring 10, to rise together in company with lid, finally open this container.
Be maintained at article under the situation of pressurized state, has the stopper that can closely insert the interior hermetic unit of container finish inside face as long as use, even take off the degree of not removing lid fully owing to reasons such as mischief make lid, can prevent at least that also this stopper from rotating together in company with lid, thereby keep the air-tightness of internal tank.And, after rupturing really in flakes, keep the leak free stopper under the effect of stopper lead ring, can rise together at least in company with lid, finally open this container.
Therefore adopt this simple structure, loosening even lid has slightly, also can keep the air-tightness of container, thereby protect the article of being adorned effectively.
