Description

Tamper-evident closure

Technical field

The present invention relates generally to a kind of lid that is used for container, particularly a kind of have show be opened the lid of device at least once of lid.

Background technology

At present, increase day by day for the demand that shows cheating system, this system clearly indicates whether that to the customer container practises fraud, and such as, filled content without permission again.Though producing the cheating sign of certain form is easier to relatively, but provide following cheating sign much more difficult, this cheating sign is not make under the situation of preventing fraud system start-up to overcome, and starts exactly to return to visually identical state then, thereby appears as without startup.

A kind of useful especially the method for anti-fraud is provided is to adopt a kind of system, and wherein, lid is positioned at primary importance at first, but in case be removed, and just only turns back to look the second place that is different from primary importance.For example US5738231 has described a kind of lid, and it has the parts that move in opening procedure, make after opening, and can't return the ridge of crossing on the container finished product.As a result, lid can only be got back to respect to axially movable position, its initial position.Document WO 02096771 has been described a kind of lid with first and second portion, and this first has inner component and exterior part.At first, under the horizontal surface of one section parts that extend of the inner component of first, and keep securely, form the reduced circumference of this part by a zone of second portion.When taking off first, this intersegmental part spare is pulled up under the zone of the reduced circumference on the second portion.Take off after the inner component of first, the zone of the reduced circumference on the second portion keeps its original size, if make when reusing first, inner component no longer can be by the below in reduced circumference zone.Therefore, between the exterior part of first and second portion, produce a gap, because at this moment this intersegmental part spare that is cut in advance below second portion is cut on the zone of reduced circumference.

In above-mentioned two pieces of prior art documents, form a gap by stopping barriers.It is approaching that the problem of this system is that barriers is easy to, and can for example take off by cutting, to eliminate the cheating sign.

The present invention attempts to address the above problem.

Summary of the invention

On the one hand, the invention provides a kind of tamper-evident closure that is used for container, this lid comprises: the first with inner component and exterior part; And second portion, wherein, exterior part can move to the second place from primary importance with respect to inner component, in primary importance, exterior part is closely adjacent with second portion, in the second place, have clog-free gap therebetween, and wherein, inner component and exterior part are suitable for irreversibly being locked in the second place, make exterior part not move and return primary importance, with closing gap, it is characterized in that this lid comprises device, be used to prevent that inner component from moving with respect to second portion, arrived the second place up to exterior part.

Therefore, the present invention relies on the barriers stopped to form therebetween gap.Can not eliminate the cheating sign so only take off barriers by cutting.

Protective device can comprise the friction gear between first and the second portion.

Friction gear can be made of two groups of hook tooths.This tooth is easy to make with plastic material.

Second portion can be connected on the container, and first can comprise a cap.Some industrial sectors need have the lid of a first and a second portion, and first comprises a cap, and second one then comprises the sleeve pipe that is connected to container; For example, alcohol industry.

Second portion can for good and all be fixed on the appropriate location on its container.Prevent like this that second portion from moving up and with space closure.

Second portion can be suitable for engaging the check fittings that links with container.This is because in some industry, and especially alcohol industry needs other measure to prevent cheating.Check fittings satisfies this requirement by preventing that container from pouring into again, does not consider other anti-fraud measure.

First can comprise escapement, is used for inner component and exterior part are locked in the second place.Escapement is a kind of simple and efficient way that inner component and exterior part are irreversibly locked together.

On the other hand, the invention provides the fabricate block of a kind of container and tamper-evident closure, this lid comprises: the first with inner component and exterior part; And second portion, wherein, second portion is connected on the container, and first is a removable top cap, the exterior part of first can move to the second place from primary importance with respect to inner component, in primary importance, exterior part is closely adjacent with second portion, in the second place, has sky between the two, clog-free gap, after this, first is movably, and inner component and exterior part are suitable for irreversibly being locked in the second place, causes when first puts back to original position, exterior part can not move and return primary importance, with closing gap, it is characterized in that, protective device is set, to prevent that inner component from moving with respect to second portion, arrived the second place up to exterior part.

Fabricate block also comprises the check fittings that can link to each other with container, and second portion is suitable for engaging this accessory.

The specific embodiment

At first, common shown in the figure with 10 lids of representing referring to Fig. 1.This lid 10 comprises: outer ratchet 30; Handle ratchet wheel 40; Optional packing seal 50; And filling machine 60.When in the aluminum hull 20 of packing into and when placing on the bottleneck 80 through tightening seal washer 70, lid 10 is suitable for forming the part of lid arrangement.

Fig. 2 A to 2F illustrates in greater detail filling machine 60.This filling machine 60 comprises bottom 61, this bottom be generally cylindrical shape and diameter and the external diameter of the container neck that links approximately equal, lid can be installed on the container neck.Bottom 61 has upper surface 62.Small diameter cylinder 63 with outside thread 65 is installed on upper surface 62.The fabricate block of bottom 61 and less cylinder 63 has the hole of running through wherein 64, in a single day opens with toilet cover and just makes container energy can content.Two groups of hook tooths 64 are set on the outer wall of less cylinder 63.

Fig. 3 A to 3F illustrates in greater detail handle ratchet wheel 40.This handle ratchet wheel 40 has cylindrical body 41.These cylindrical body 41 1 end openings, and the other end is by top board 42 cappings.On the inside face of the open end of cylindrical body 41, form hook tooth 43.In addition, on the outside face of cylindrical body 41, form screw thread 44.Between screw thread 44 residing outside faces and hook tooth 43 residing inside faces, step 45 is set.The reason that step 45 is set will illustrate below.On the outside face of the cylindrical body 41 of a relative end, also form two groups of hook tooths 46 with open end.At last, on the inside face of cylindrical body 41, form another screw thread 47, but axially be positioned at hook tooth 43 tops.

Fig. 4 A to 4F illustrates in greater detail outer ratchet 30.Should outer ratchet 30 have and wherein run through porose 32 cylindrical body 31.On the inside face of the upper end of cylindrical body 31, form one group of hook tooth 32.On the lower end of cylindrical body 31 and inside face, form screw thread 34.At last, cylindrical body 31 has endless belt 35, and this endless belt is positioned at the lower end of cylindrical body 31, and hole 32 is dwindled.

Fig. 5 illustrates the section-drawing of the lid 10 that assembles, and this lid comprises filling machine 60, handle ratchet wheel 40 and outer ratchet 30.Shown in the lid 10 with container neck 80 combined.Filling machine 60 is by being installed in tightening seal washer 70 fix in position on container in the neck 80.

Shown in lid 10 be in beginning and end open position just.This shows that from the following fact promptly the endless belt 35 of ratchet 30 flushes applying with respect to the upper surface 62 of filling machine 60.

Fig. 5 illustrates the screw thread of various hook tooths and filling machine 60 and the interrelation between the

ratchet member

30,40.

Fig. 6 illustrates and covers another section-drawing of 10.But, in the figure, lid is opened especially, as shown in the figure, has gap " G " between upper surface 62 and endless belt 35.

The state that partially opens among Fig. 6 is realized by outer ratchet 30 is rotated with respect to filling machine 60.This rotation makes the screw thread 34 of outer ratchet 30 ride on the screw thread 44 of handle ratchet wheel 40.

Hook tooth

32 and 46 does not stop this relatively rotating, because these hook tooths are arranged such that when they rotate with described unfolding mode, and not interlocking of hook tooth, and the method for only knowing with hook tooth is overlapped.

On the contrary, when lid just is being opened, hook

tooth

64 and 43 interlockings.Guarantee that like this handle ratchet wheel 40 and filling machine 60 do not rotate each other at first.

Following feature also is shown in Fig. 6 in addition, and promptly endless belt 35 rises and leaves upper surface 62, thereby forms gap " G ", but the step 45 that moves axially on the downside that is subjected to handle ratchet wheel 40 of endless belt 35 limits.In case reach this position, outer ratchet 30 can't be further rotated with respect to handle ratchet wheel 40.

Therefore, outer ratchet 30 will overcome the

hook tooth

64,43 of interlocking with respect to the continuous rotation of filling machine 60, thereby filling machine 60 can be backed out from handle ratchet wheel 40 separately.This interaction by

screw thread

65 and 47 realizes.At last, the fabricate block of inside and

outside ratchet

40,30 will separate with filling machine 60, make that the content in the container can distribute by the hole on the filling machine 60 64.

Fig. 7 illustrates filling machine 60 and the container neck 80 that does not have inside and

outside ratchet

40,30.

When the needs closing containers, inside and

outside ratchet

40,30 is placed on the filling machine 60 and rotates, but make

screw thread

65,47 mutual actions towards the direction of closing usually.Hook

tooth

64,43 is designed to when each other towards the rotation of described closing direction, not interlocking of hook tooth and only overlapping each other.

The fabricate block of inside and

outside ratchet

40,30 is only rotatable to reach degree shown in Figure 6.This is because the downside of the hook tooth 43 on the handle ratchet wheel 40 will be against on the upper surface 62 of filling machine 60, has prevented any further motion to axial thus.In addition, when outer ratchet 30 when closing direction rotates,

hook tooth

46,32 is interact with each other.Prevent that so inside and

outside ratchet

40,30 from having any relatively rotating.This mutual action between the

hook tooth

46 and 32 also plays the effect that prevents that outer ratchet 30 is rotated along closing direction, is only opened minutely even cover 10.

As long as cover 10 and be opened once, between the downside of endless belt 35 and upper surface 62, will produce gap " G ".This gap will be closed once more never, as mentioned above, because the hook tooth device stops this situation to take place.Even inside and

outside ratchet

40,30 is taken off and then uses from filling machine 60, this gap still exists, and relatively rotates because hook

tooth

46,32 prevents inside and

outside ratchet

40,30.

In addition, though not shown, the upper end of outer ratchet 30 can be sealed, thereby can not overcome

opposed hook tooth

46,32 with instrument.

In addition, owing to remain tubular body wall 31, under the situation of ratchet 30, opposed

hook tooth

46,32 can not be changed from following quilt outside not damaging significantly.

So these combination of features prevent that lid from by " replacement ", so that eliminate this gap " G ", therefore, covering much more superior than known systems in this respect.

Lid 10 is combined with ROPP (seaming cautions against stealing) metal case 20 shown in Fig. 8 A to 8C, and this metal case is as a kind of sheath.

This shell 20 is divided into three main portions: top 21; Middle part 22; With bottom 23.These three parts were opened by the line of two frangible bridge-shaped objects in 24,25 minutes.Top 21 is fixed on the outer ratchet 30 by the device of knowing, so that open lid, this top 21 is firmly grasped and rotated.When outer ratchet 30 rotates and axial motion when leaving filling machine 60, first line 24 of frangible bridge-shaped object disconnects.The effect of anti-fraud is played in this fracture.As mentioned above, the gap " G " that produces when lid is opened will be regarded as the gap between top 21 and the middle part 22, shown in Fig. 8 C.The in addition effect of anti-fraud device also can be played in top 21, because this device ring is around outer ratchet 30, and thus also around handle ratchet wheel 40, and by such as crimping or glue together this mode and be attached on the outer ratchet 30.Therefore, opposed

hook tooth

46,32 is difficult to approaching more, so under the situation that does not have apparent damage upper shell 21, in fact can not reinstall lid.

Middle part and

bottom

22,23 are used to guarantee that filling machine 60 can not take off from container neck 80.Reach this point and be because bottom 23 convolutions on neck 80, this can see from Reference numeral 26.Outer ratchet 30 remains in the top 21 by crimping, and this can see from Reference numeral 28.In addition, middle part 22 convolutions are on the bottom 61 of pouring attachment 60, and this can see from Reference numeral 27.Like this, if the can part is taken off from container neck 80, then 25 fractures of rolling off the production line of frangible bridge-shaped object, thus play the effect of preventing fraud.

Fig. 8 B illustrates the lateral plan of a kind of embodiment of lid, and this lid comprises ROPP, and wherein, has taken off with handle ratchet wheel 40 and outer ratchet 30 on top, exposes filling machine 60.Filling machine 60 is connected on the container 80 by being added by the bottom 23 of convolution ROPP thereon and middle part 22.Although the crimping of Lun Shuing is as

housing parts

21,22,23 being fixed to the mode of covering on 10, also can adopting other method certainly, for example gummed or welding here.

The other feature of handle ratchet wheel 40 can be found out in Fig. 3 A to 3F.These features are that two groups of hook tooths are formed at and are with on 48, and this is connected on the other parts of handle ratchet wheel by fillet 49 with 48.Two groups of teeth closely are engaged on the inside face of outer ratchet 30 on the corresponding tooth 32.Yet the periphery with 48 is slightly less than the periphery in the hole of outer ratchet 30.This makes the flexibility that can have to a certain degree with 48, will be explained below.Bar 49 is arranged around the peripheral intervals of handle ratchet wheel 40, and form " window " 49A between them.This layout is also for 48 flexibilities that provide to a certain degree, makes it can be deformed into non-circular when opening at first when lid.This can slip over

hook tooth

46,32 as mentioned above each other.This flexibility is necessary, because two groups of

hook tooths

46 and 32 are arranged to such an extent that they very closely are combined together.This compactness guarantees that outer ratchet 30 can not rotate with respect to handle ratchet wheel 40 along closing direction, because this relatively rotating can be eliminated gap " G ", and eliminates the sign that lid has been opened thus.

Though illustrate by this way, should be appreciated that so that other layout that hook tooth can slip over each other also is possible.In addition, the quantity of hook tooth 46 also can be different from described two groups.

In another embodiment, the outside face of the lower end of handle ratchet wheel 40 (being the part that has hook tooth on its inside face) is managed to make do light tone.This can emphatically point out the existence of gap " G " because just should the surface in case lid by initial opened just can be visible.

Although top lid of the present invention be with the line description that is combined into of metal ROPP, also can make the combination of materials of lid and other type.And this lid also can be attached on the container that links by the alternate manner of for example bonding or welding.In addition, because itself live telecast of the basic combination of inside and outside ratchet and filling machine is air tight, so under situation, also can use this combination without any the oversheath of other form.

At last, although hook tooth the 64, the 46th so that lid can proper operation necessary friction gear be described, also can use other device.Such as selecting coarse surface that enough friction force are provided, so that common " locking " filling machine 60 and handle ratchet wheel 40 when opening at first, and outer ratchet 30 is with respect to handle ratchet wheel 40 rotations, but after gap " G " formed and under the situation that ratchet 30 continues to rotate outside, can not provide enough friction force to prevent that handle ratchet wheel 40 and pouring attachment 60 from rotating each other.

Can adopt other device for example to use material such as VELCRO (RTM) or this class of adhesives.
