Description

Plastic anti-counterfeit safety cap

Technical field

The present invention relates to a kind of improvement that can confirm the anti-counterfeit safety cap of making by synthetic resin (pilfer-proof cap) in improper Kaifeng.

Background technology

Common plastic anti-counterfeit safety cap is generally by grappling bottleneck, being constituted to the threaded cap of under shed and the hoop bar (tapper-evidenceband) that is configured in this threaded cap lower end.Threaded cap and hoop bar link with the bridge portion that can break, and form such structure on the hoop bar, promptly constitute the locking part of the sealed ligule in the lower end of flange etc. on bottleneck.

This anti-counterfeit safety cap has threaded cap integrally formed with the hoop bar, also has threaded cap and hoop bar to make respectively, utilizes the hoop bar to resist elastomeric deformation with screw thread and chimeric (or claiming assembly type) that becomes by two component set-ups.

As the anti-counterfeit safety cap of the latter, concrete report was once arranged, public strictly according to the facts clear 51-18195 communique, special fair 3-75424 branch newspaper, real fair 4-9330 communique, and real fair 4-30113 communique by two component set-ups.These technique known, the hoop bar can be from being separated by the bridge portion bonded assembly upper and lower that can break, and the top of hoop bar is connected the lower end of threaded cap, forms and bottleneck bead lower end bonded assembly connecting portion in the bottom of hoop bar.

As further introducing, the real anti-counterfeit safety cap of being reported for public clear 51-18195 number forms the outside flange part of radius in the lower end of threaded cap in above-mentioned these known technologies, on the top of hoop bar from this flange part of outside clamping.In addition, special fair 3-75424 number, real fair 4-9330 number and the real product of being reported for fair 4-30113 number are the upper end of hoop bar to be entrenched on the inner peripheral surface of threaded cap bottom constitute.

Form the occasion that integral body is parts at threaded cap and hoop bar, both wanted to accomplish molding easily during fabrication, it is difficult making locking part to the bottleneck flange have solid structure again.For this reason, report as above-mentioned each communique, threaded cap and hoop bar are constituted two parts respectively, owing to can make locking part that solid structure is arranged to the bottleneck flange, prevent from not draw just to make bridge portion Kaifeng, have and improve the advantage of sealing performance (can confirm to have or not the performance in improper Kaifeng).

In addition, product attractive in appearance need be paid attention to, edge lines such as the gold of ring-type or silver color can be formed in the lower end of lid for this class of container cover as used for cosmetic.Also can owing to have feeling of high class and special result, can significantly improve the aesthetic feeling of product to anti-counterfeit safety cap by the design of duotone method.

And, like this as a kind of two-tone method of designing, in the technology of above-mentioned each report, all consider to utilize threaded cap is separated the product that constitutes anti-counterfeit safety cap with the hoop bar, and change threaded cap and the color that binds round bar, on the hoop bar, pay color with methods such as vacuum coatings.

But, reported for public strictly according to the facts clear 51-18195 number, the chimeric hoop bar of bead that forms in the threaded cap lower end, when utilizing the injection moulding manufactured, though molding easily, it is easy to process, but, must improve aesthetic feeling because the external diameter of threaded cap and hoop bar has big difference.Promptly almost there is not the design-calculated freedom.

On the other hand, fair strictly according to the facts 3-75424 number, real fair 4-9330 number, real fair 4-30113 number like that, make the top of binding round bar be entrenched in the inside of threaded cap, shown in Figure 11 in the fair strictly according to the facts 4-30113 communique, threaded cap can form straightsided shape, yet, because can form the bottom (exposed parts) and the same footpath of the outer peripheral face of threaded cap of hoop bar, though so can improve aesthetic feeling, but trouble that exists the sealed excessive cutting of the inner peripheral surface hoop bar be formed on threaded cap to cause again.

Goal of the invention

The present invention is developed in view of above-mentioned existing actual conditions, and its purpose is to provide a kind of anti-counterfeit safety cap by two component set-ups, and this anti-counterfeit safety cap neither loses the easiness of manufacturing, can improve aesthetic feeling again.

For achieving the above object, the anti-counterfeit safety cap of synthetic resin of the present invention has on the externally threaded bottleneck by being screwed in outer peripheral face, plastic threaded cap at the bottom of Open Side Down the tubular band, constitute with the plastic ring bodies of installing in this threaded cap lower end, threaded cap and ring bodies are made respectively, on described ring bodies, relatively on the bottleneck with the following formation locking part of flange, it is characterized in that lower end at described threaded cap, be provided with the dip portion of ring-type of overlapping with the inner peripheral surface of ring bodies etc. integratedly by the bridge portion that can break, at the outside of this dip portion and the inner face of ring bodies, closure is set, chimeric because this dip portion and ring bodies utilize elastomeric resistant function, threaded cap and ring bodies can not be locked together in together between mutually with breaking away from.

Press said structure, the closure that is arranged on the dip portion of threaded cap forms at outer peripheral face, even enter the inner sides of radius state, utilize injection moulding also to form easily to be provided with threaded cap with sealed band dip portion such as ring flange so dip portion is by the threaded cap outer peripheral face.Owing to there is no need to make the external diameter of this dip portion big, also just there is no need to make the external diameter of ring bodies (hoop bar) excessive than the external diameter of threaded cap, its result can make the external diameter of threaded cap and ring bodies all claim, makes integral body do exquisitely.

In addition, threaded cap and ring bodies can be used the material of different color respectively, method affords such as vacuum available plated film apply metallochrome etc. in the outside of ring bodies, again because make anti-counterfeit safety cap become duotone also to carry out easily, can play making product have feeling of high class and outstanding effect, can improve aesthetic feeling extraordinarily.

Therefore, by method of the present invention, not only do not impair the easiness of manufacturing, and can improve the aesthetic feeling of anti-counterfeit safety cap extraordinarily.

Also have, structure as claimed in claim 2 can make ring bodies keep paying closely with spring leaf, is trapped among very stable being located on the bottleneck just like ring bodies, can improve the aesthetic feeling of product.And, because being in the base portion and the spring leaf of ring bodies, the dip portion of threaded cap forms the state of seizing on both sides by the arms, so have the advantage of the installation strength that can improve threaded cap and ring bodies from inside and outside both sides.

The specific embodiment

Fig. 1-Fig. 6 is the state of the embodiment of the invention 1.As shown in Figure 1, make tooth form screw thread 3, below tooth form screw thread 3, make flange 4 simultaneously at the outer peripheral face of bottleneck 2.In addition, make one small-borely in the upper end of bottleneck 2, setting-in is by plastic nozzle 5 on this small-bore 2a.

Anti-counterfeit safety cap 1 by be screwed on the bottleneck 2, downwards the threaded cap 6 at the bottom of the opening tubular band and the ring bodies 7 that is installed in these threaded cap 6 lower ends constitute.The both makes by injection moulding of synthetic resin such as polypropylene.Be embedded with packing seal 8 on the top of threaded cap 6.

As shown in Figure 2, the dip portion 10 that connects ring-type in the lower surface of the 6a of tube portion of threaded cap 6 by the bridge portion 9 of many (embodiment as shown in Figure 3 is 6) integratedly.This dip portion 10 is arranged on the radius side than the outer peripheral face of threaded cap 6, and on the outer peripheral face of dip portion 10, constitutes the ring flange 11 as an embodiment of locking part.Bridge portion 9, make its upper end the less formation one important actor shape of sectional area.

As shown in the Examples, make bridge portion 9 form the important actor shapes, when Kaifeng since the upper end stress concentration of bridge portion 9 together velamen break, the vestige that the lower end of threaded cap that can be behind Kaifeng prevented or avoided residual bridge portion 9 can improve aesthetic feeling.

Ring bodies 7 forms in the top with the lower end of threaded cap 6 and is identical substantially external diameter, and as a whole, form the profile that expands the lower end (also straight flange), the locking part of ring flange 11 tablings of side face formation within it and described dip portion 10, as an embodiment, this locking part is the endless groove 12 around full Zhou Yanshen.Utilize the elastic deformation of ring bodies 7 and dip portion 10, make endless groove 12 and ring flange 11 tablings together, ring bodies 7 can not be installed on the threaded cap 6 with breaking away from.

In addition, make under the chimeric state of endless groove 12 and ring flange 11, the lower end that threaded cap 6 is close in the upper end of ring bodies is provided with.As shown in Figure 2, the position in the upper surface of ring bodies 7 between the adjacent bridge portion 9 is provided with the protruding upward flange 13 slightly little than the bulge size of bridge portion 9.This flange 13 can prevent the 9 crooked deformation of bridge portion when ring bodies 7 and dip portion 10 tablings.

Inner peripheral surface at ring bodies 7, constitute sealed pawl 14 and spring leaf 15 along its circumferencial direction with intermeshing, sealed pawl 14 is to tangle an example that keeps the locking part that ring bodies 7 can not upwards move below the flange 4 of bottleneck 2, and spring leaf 15 is the outer peripheral face rubber-like spring leafs that are positioned at flange 4.When making these sealed pawls 14 and spring leaf 15 distortion, because of threaded cap 6 is torqued into bottleneck 2, as shown in Figure 5, sealed pawl 14 is positioned at the below of the flange 4 of bottleneck 2, and spring leaf 15 is elastically-deformable state in the outside of flange 4.

This occasion, sealed pawl 14 can be in the elastomeric settings of root of the flange 4 that is equivalent to bottleneck 2, but during design, should avoid making when threaded cap 6 is torqued into bottleneck 2 resistance of sealed pawl 14 excessive, both made just that threaded cap 6 is torqued into, and sealed pawl 14 can not be crossed bead 4.To this, when constituting sealed pawl 14 and spring leaf 15 respectively, following advantage should be arranged, that is: should guarantee really to make sealed pawl 14 be locked together in flange 4 below, can keep 15 pairs of flanges of spring leaf, 4 relative ring bodies 7 to be in stable status again.

Size in the radius of setting spring sheet 15 is smaller slightly to projecting inward size than sealed pawl 14.Simultaneously, about the width and the interval of sealed pawl 14 and spring leaf 15, under the condition that does not influence its function, can set arbitrarily.

Shown in Fig. 5 (B), when threaded cap 6 tightens bottleneck 2, set the dip portion 10 of seizing threaded cap 6 on both sides by the arms with the base portion and the spring leaf 15 of ring bodies 7.Therefore, the chimerism of ring flange 11 and endless groove 12 can be guaranteed, the installation strength of double thread lid 6 and ring bodies 7 can be improved extraordinarily.

Make the mould of threaded cap 6 of injection moulding, shown in the dashdotted part of Fig. 2, the I type 16 that the die cavity that embeds threaded cap 6 is arranged, constitute the II type 17 of bridge portion 9 and dip portion 10 outsides, constitute the IV type 18 of bridge portion 9 and dip portion 10 inner faces and be the IV type 19 of the tooth bar of the inner face threaded portion that constitutes threaded cap 6.Rotate tooth bar III type 19 on one side from threaded cap 6, can draw dial, inner face in the lower end of the tube portion 6a of threaded cap 6, III type 18 formation meshing nicked groove 20 on one side.

I type 16, III type 18 and IV type 19 move along the direction of principal axis of threaded cap 6, II type 17 along radial direction move form combined.

Ring bodies 7 utilizes elastic deformation by a pair of die forming that axially moves, and promptly pulls out mould with so-called pressure extracting method from sealed groove 12.

In above-mentioned moulding, owing to can easily form ring flange 11 in the outside of dip portion 10, so also just can easily make dip portion 10 place the outer peripheral face inner sides of radius of threaded cap 6.Its result becomes excessive can prevent the external diameter of ring bodies 7, though be two component set-ups, but do exquisitely, can be designed to the outstanding style of visual impression.Simultaneously, owing to form bridge portions 9, make bridge portion 9 is set on the high position, upper end of ring bodies 7 becomes easy at threaded cap 6.Therefore, still have with the threaded cap 6 at the bottom of the common tubular band identical shapedly at Kaifeng rear thread lid 6, the appearance behind the Kaifeng might as well.

And shown in the style of Fig. 6, for example threaded cap 6 is by white synthetic resin manufacturing, and 7 of ring bodies are by red synthetic resin manufacturing.Because the variation of the color of threaded cap 6 and ring-type 7, can give with a kind of feeling of high class of anti-counterfeit safety cap or play special effect, therefore, can improve the aesthetic feeling before and after the Kaifeng significantly.

Above-mentioned threaded cap 6 and ring bodies 7 are to make with the synthetic resin of different color, but also can not make in this way or on above-mentioned method for making, shown in two long and short dash lines among Fig. 2, side at the band of synthetic resin etc. is used vacuum coating metallo-dubs 21, the outer peripheral face of ring bodies 7 is contacted with the overlay of dubs 21 colors, in rotation ring bodies 7, the output of dubs 21 is carried out on the limit, the limit applies color with the outer peripheral face pushing dubs 21 of hot rubber cylinder (not shown) at ring bodies 7 on the outer peripheral face of ring bodies 7.Like this, use dubs 21, can pay various metallo-colors such as silver color, gold, chromium look easily, can obtain to a kind of effect of aesthetic feeling.

In addition, be under the situation that bridge portion 9 is set, to constitute threaded cap 6 in an embodiment, but under the situation that does not constitute bridge portion 9, cut the bottom of the tube 6a of portion, also can constitute bridge portion 9 and dip portion 10 with cutter.Simultaneously, the locking mode as dip portion 10 and ring bodies 7 can form endless groove in dip portion, forms ring flange at ring bodies 7.And dip portion 10 is not only limited to the formation ring-type, can along the circumferential direction extend to form discontinuously yet.

That shown in Figure 7 is the embodiment 2 of the outside warpage of ring bodies 7, is to add a plurality of ring-type muscle to constitute in the outside of ring bodies 7, and can utilizes heat the outer peripheral face that suitable means are applied to many lines ring bodies 7 such as to duplicate.

Fig. 8-Figure 10 shows that form of the embodiment of the invention 3.At embodiment 3, circumferentially extend at the outer peripheral face of the dip portion 10 of threaded cap 6 and to constitute outside ring-type pawl 22.On the other hand, along the circumferential direction intermittently extend many (being 4 in Fig. 9) the inside sealed pawls 23 that lock together to outer ring-like pawl 22 that constitute with described dip portion 10 at the inner peripheral surface of ring bodies 7.

This occasion, and the position between the adjacent inside sealed pawl 23 in the inner peripheral surface of ring bodies 7 constitute to not sealed recessed outer 24 of outer ring-like pawl 22, at this recess 24, to the sealed pawl 14 of flange 4 formations of bottleneck 2.And, the position of inside sealed pawl 23 opening (peristome is represented with symbol 25) downwards in the bottom of ring bodies 7.By the connecting portion 26 of seizing peristome 25 on both sides by the arms spring leaf 15 is set.

At this embodiment, 23 circumferencial directions along ring bodies 7 of inside sealed pawl partly are provided with, because peristome 25 arranged, and the easy degree of molding when not losing moulding, and can strengthen inside sealed pawl 23 to projecting inward size, therefore two sealed

pawls

22,23 can be tangled securely.Its result, ring bodies 7 can be fixedly mounted on the threaded cap 6.

In addition, sealed pawl 14 is connected along the wide main body with ring bodies 7 of its full width, so can not damage the supporting role of 14 pairs of flanges 4 of sealed pawl.And, the same with embodiment 1, because the main part and the spring leaf 15 of ring bodies 7 are seized outside sealed pawl 14 on both sides by the arms,, can improve the installation strength of double thread lid 6 and ring bodies 7 more so two sealed

pawls

22,23 are easy to be locked together in together.

In the various embodiments described above, back, Kaifeng ring bodies 7 remains on the bottleneck 2, but the form that also can break constitutes dip portion 10 and ring bodies 7.In addition, during requiring on design is arranged, also the external diameter of ring bodies 7 can be set at big than the external diameter of embodiment.

In addition, sealed pawl is set and spring leaf is a kind of stable form, also can be useful in the occasion that ring bodies constitutes bridge portion at ring bodies.

Also have an advantage, promptly as bottle (main body of container) and lid with identical materials (for example using polypropylene) manufacturing, then after container breaks a seal, again during repeated usage, take off ring bodies from bottleneck easily.
