Abstract

A moulded closure for a blow moulded bottle of the type in which drinks, sauces and shampoos are sold has two parts. The screw cap (14) has an integral nozzle and a tamper proof band (24) connecting it to the bottle neck. The nozzle is covered by a cover (36) hinged to a ring (38) which is captive to the screw cap. The ring is free to rotate beneath a projecting bead (32) on the screw cap and the hinge (46, 48) flexes to allow arcuate displacement of the cover to one side of the nozzle and an integral tongue (46 )allows the user to park the cover at 120 DEG to the nozzle. Tongue (46) arrests the cover at 160 DEG to the nozzle when the user tilts the cover further open and tongue (46) snaps over the bead (32). The cover (36) is attached to the ring (38) initially by frangible bridges (42) so that the ring acts as a second tamper proof band.

Description

Cover adapted to open without authorization for displaying

Technical field

The present invention relates to a kind of cover adapted to open without authorization for displaying, its be used for dispense liquid and gel bottle, extrude packing and similar molded container.

Background technology

Must make the public of shopping can contact product on the shelf such as the retail shop in supermarket.The shopper needs taste or other characteristic of test(ing) liquid product to attempt them usually.In this case, next buy this unit the shopper will bear this loss.A kind ofly serious may be, people toward bottle in added a kind of objectionable impurities, and another person buys subsequently and has used it.In order to prevent this danger, bottle and molded small container are sealed by cap usually, and whether this cap can show to have without authorization opens.For this reason, the cover adapted to open without authorization for displaying that the shape of some bottlenecks is molded is protected simply, and some have such as the bottle of drinking container or liquid cleaner distributing box and container presses/the pull-up Dump valve, and all there is specific technical difficulty in these.

U.S. Pat 4043475 has been described a kind of children's of preventing moulded closure, and this lid also is used to prevent to arrogate to oneself out, and has a cap that is hinged to a clamping band, and this clamping band is for good and all installed by the protruding pearl of bottleneck.This clamping band keeps the location and stops its rotation to be opened without authorization avoiding on bottleneck.

U.S. Pat 6152320 has been described a kind of control nozzle cap, and it is used to be provided with the beverage bottle of a nozzle.This cap is connected to a control band by first and second hinges, the combination of first and second hinges can make this cap connect via 180 degree.

Summary of the invention

Device of the present invention provides a kind of molded bottle cap, the bottle cap of this form has a nozzle that limits an outlet, nozzle closes on this outlet and comprises a neck, one captures (captive) ring cooperates with this neck, the periphery of this ring limits a minor arc and an auxilliary arc, one nozzle cover is captured ring with this and is connected, and a hinge is connected to this to this nozzle cover and captures ring above this auxilliary arc, and easy bridge cut-off is connected to this to this nozzle cover and captures ring above this minor arc.

This nozzle can be the part of conventional screw cap.This nut thereby can be connected to bottleneck by easy bridge cut-off or tearing tape.

Nut can be arrogated to oneself out band by easy bridge cut-off or tearing tape and and is connected, and this is arrogated to oneself out band and cooperates with flange or protruding pearl on bottle or the container.The skirt section can be ripply or be fixed to bottle or container, prevents rotation or removes generation when opening the bottle rotary nut with convenient user.

Another aspect of the present invention provides the combination of bottle or container and above-mentioned cover adapted to open without authorization for displaying.

Be easily, nozzle is molded as the part of nut, thereby holistic bottle cap is provided, and comprises bonded assembly nut and nozzle cover, available bottle placer can on the canning line of factory.Nut makes to arrogate to oneself out and shows that band keeps dangling from the skirt section of nut like this.Usually, bottleneck has the circumferential flange that closes on the mold-formed bottle screw thread, arrogates to oneself to open to prevent that band from embracing this bottle flange, and is received nut by tearing tape or easily broken bridging.In the bottle cap field, easily bridge cut-off is used in and cover between the part, and owing to the screw action of a part separates, the tearing tape that is used for part is not outwarded winding, but obvious they are equal in this manual.

Arrogate to oneself to open preventing that band from can have ripple or being made and clamping flange, stop when being the uncork rotary nut and remove or rotate with convenient user.Usually, the valve protection cap with beverage bottle of nozzle in use maintains the original state, because the user only needs to open nozzle cover and can drink and get final product from capturing ring.If bottle is become repeated usage by can or before drinking sealed thin need be removed the valve protection cap of just need outwarding winding.

Feature of the present invention is, bottle placer installs to lid on the bottle, thing in the air-tight bottle simultaneously, and do not need to apply disc seal to bottleneck.This can finish in two ways.Nut can have a circular interior sealing, and sealing can be supported a film phonograph seal, to get rid of the pollution of thing in the bottle, for example spore.Instead, nozzle can be erect integratedly and be superimposed upon on the nut, and puts in the nut, produces in the bottle apical margin in use altogether that crown of roll goes out neck ring, and an annular support surface is provided like this, is used to accept film phonograph seal.

Bottle placer can be executed the material machine through inverted bottle cap by a disc seal like this, and executing the material machine is that capsuling machine is prepared bottle cap.

Nozzle cover can have the stopper of one, and stopper is pressed and is installed in the jet expansion.Stopper flange circle, that be rotated down, its inside face from nozzle dangles.Selectively, nozzle cover can have molded groove thereon, and it is pressed and is installed in the jet expansion.

Even bottle and its bottle cap are dropped, nozzle cover and capture ring and also keep together with bottle cap.

Capture the enough looselys of ring and be installed in the neck of nozzle, allow with finger or (on) chin rotate and capture ring.This feature reduces the possibility that the nozzle cover hinge connects and capture the ring damage.The thin thickness of the comparable nozzle cover of thickness of band (strips) or the same depends on desirable performance.

Capture ring and nozzle cover and limit a hole together, this hole is striden across by a secondary flexible hinge band, and this hinge band connects nozzle cover and captures ring.This hinge band is connected or near their intermediate point, nozzle cover is produced a common hinge axes.The hinge band is crooked in use, and strengthens the two-stable position of uncover.When the user flicked nozzle cover with finger from capturing ring, the hinge band made nozzle cover and nozzle plane approximately become 120 degree angles to a direction bending.One tongue strides across described hole from nozzle cover and extends to capturing ring.The purpose of tongue is to slip over the nozzle neck surface, and against protruding pearl, this protruding pearl defines the border of nozzle neck and nozzle itself up to it.It rests on this place, makes nozzle cover become 120 degree angle lappings oblique with respect to the nut plane, makes tongue cross protruding pearl up to further elastic force, makes the angle of nozzle cover be increased to 150 degree-160 degree.

The bottle cap of this form is applicable to the bottle and the packing of beverage, flavoring, shampoo and body gels.

The specific embodiment

Bottleneck 6 has an apical margin 8 and a maintenance flange 10 near shoulder.Between this apical margin 8 and flange 10, be bottle screw thread 12.This bottle made by PET blowing typically.This lid is injection-molded typically to be made.

Nut 14 has a skirt section 16, and this skirt section has a periphery that ground 18 (see figure 2)s.The inside face in this skirt section has an internal spiral threads 20, the screw thread fit on this screw thread and the bottleneck.The top in this skirt section has a convex shoulder 22, and this convex shoulder covers on the apical margin of bottle.

Skirt section 16 is connected to one by easy bridge cut-off 26 (see figure 3)s and arrogates to oneself to open and be with 24.This band covers and keeps on the flange 10, and when valve protection cap was released, this bridge is fracture just, remained on its position and arrogate to oneself out band.This nut and nozzle 28 are one.

The lower rounded edge of nozzle is advanced by leaps and bounds in the apical margin of bottle, is used to paste selectable sealed foil 30, is not polluted by the biosome such as spore with a thing in the protection bottle.Nozzle has the pearl 32 of maintenance at circumference.The top of nozzle has an outlet 34.

One separates molded nozzle cover 36 has two parts, provides one second to arrogate to oneself out display structure.The bottom is a nozzle ring 38, and it has consistent profile, cooperates with these circumferential bead 32 downsides.Nozzle cover 36 is connected with this nozzle ring 38 by easy bridge cut-off 42, and this easily broken bridged ring extends around the main portion of this circumference.The residue slave part of this circumference is occupied by a hinge component.This assembly is made up of window 44, and the tongue 46 that this window is spaced apart separates.In a single day the user smashes bridge tags or tearing tape when ring separates, and the hinged of these tongue both sides is with 48 to allow lid to open or close.

Nozzle cover has a finger limit 50, is used to open nozzle cover.Nozzle cover also has a stopper 52, when nozzle cover 36 is pressed and when cooperating with nozzle, this stopper enters outlet 32.The thickness of hinged band (0.2mm) is thinner slightly than nozzle cover (1.00mm), and has a crooked knot 54, and when hinged band was crooked shown in Figure 4 and 5, this bending knot allowed hinged band to extend a little.Extend one when the length of hinged band is enough to make lid to be opened and open radian.Tongue rises on the curve of circumferential bead and is resisted against on the protruding pearl, makes nozzle cover typically become the angle of 120-130 degree with the jet expansion plane.

Nozzle ring 38 freely rotates on nozzle, and with the downside butt of protruding pearl 32.Nozzle cover 36 is with 48 to be connected with nozzle by hinged, and this can make the flexible position in Fig. 4 of lid.In this position, tongue 46 reside in protruding pearl 32 below.Nozzle ring 38 tilts slightly with respect to dwell point.Nozzle cover 36 becomes 120 degree angles with nozzle plane.If the drink person pushes nozzle cover again, tongue 46 plays excess convexity pearls 32 and tilts near 180 degree, as shown in Figure 5, and becomes 160 degree angles with nozzle plane.Tongue applies a downward power to nozzle cover, makes the more close nozzle of nozzle cover, but still remains on the hinged free bend of being with.

When the user opens lid, when exposing nozzle and coming to drink, if the valve protection cap overslaugh is drunk, just may rotate to lid and nozzle ring the position of hope with finger or chin from bottle with a hand.For this purpose, the nozzle ring loosely is installed on the nozzle.

With reference to figure 7-10, use a hinge 60 to connect nozzle cover and ring with flexible loose-leaf hinge lines 62, just replaced a secondary hinge with a hinge 60.Such hinge is described in the U.S. Pat 6152320.It is identical that the limit 64 in hole and tongue 46 play a part, and allows lid that nozzle is kept a parked position.

We have found that the advantage of the foregoing description is:

If 1 upper line of weakness in working order does not rupture, client knows that bottle is not opened so.

If 2 upper line of weakness in working order do not rupture, client knows that a bottle interior thing does not lose so.

3, nozzle cover is connected with cover adapted to open without authorization for displaying, and it can not lost no matter nozzle cover is removed how many times, makes client can drink or use a bottle interior thing.

4, cover adapted to open without authorization for displaying can be made by the color of two kinds of contrasts.

5, the rotation of nozzle cover can be by a manual manipulation.

6, the hinge band makes thinlyyer than other control piece, and the life-span of cover adapted to open without authorization for displaying is expected to prolong.

7, hinge assembly makes the manufacturer change the opening angle of nozzle cover by the length that changes hinge and tongue.

8, processing does not have complexity and molded easy so.

Should be appreciated that the wording of using in the specification sheets " comprises " that being interpreted as it comprises form, promptly wording " comprises " adding of not getting rid of other element.

Should be appreciated that, do not break away from groundwork of the present invention, the present invention can carry out various improvement and/or increase.Thereby think that these improvement and/or increase fall into scope of the present invention.
