Description

Container cover

Technical field

The present invention relates to a kind of container cover, particularly be suitable for being applied in the lid of container threads end.

Background technology

US6543634 discloses a kind of threaded cap, and it comprises that inside is provided with the cup of threaded portion, and this threaded portion is suitable for the thread neck part engagement with the mode of form fit combination and bottle.This lid also is included in the tamper-evident ring (tamper-evident ring) that a plurality of bridgewares place is connected to the cup lower edge.This tamper-evident ring comprises the cylindrical wall that is provided with upper limb, and bridgeware extends out from this upper limb, and this cylindrical wall has relatively thin thickness.The join domain of cylindrical wall in the bottom is connected on the ring muscle (bead) that is limited by outside face and inside face, and this surfaces externally and internally is parallel to each other and is all cylindrical.Ring muscle thickness is obviously greater than the thickness of the cylindrical structural that is positioned at its top.The a plurality of tongue pieces that extend out from join domain are arranged on the position of also facing the cup diapire with respect to the cylindrical wall face tilt.

When disclosed lid puts on bottle in US 6543634, tamper-evident ring and tongue piece distortion so that make this tamper-evident loop mapping be located at neck ring on the bottle below.If subsequently lid is outwarded winding, this tongue piece just comes to the lower surface of neck ring, thereby the tamper-evident environmental protection is held on the position of contiguous neck ring.The moment of torsion that in the process of outwarding winding, applies thereby can make bridgeware fracture by the user, and remove cup, and tamper-evident ring and bottle connect together.

The shortcoming of disclosed lid is in US 6543634, it is put on along normally very inconvenient on the bottle of bottling product line high-speed mobile, and may be apply inappropriate.

In fact, the internal diameter of tamper-evident ring is near the external diameter of neck ring, and in this structure, the structure of tamper-evident ring is really up to the mark.

In the first bottling stage, lid must be put on the screwed neck of bottle, and in subordinate phase, it must be fastened on the screwed neck, so that the material in the bottle is isolated from the outside.In these phase process, must on lid, apply sizable moment of torsion, so that the tamper-evident ring deforms by expansion, till it slides to the below of screwed neck and neck ring.

Yet, in some cases, bottle closure can not be lived, this is because the moment of torsion that is applied on the lid is not enough to lid is pressed onto on the neck of bottle, perhaps, if moment of torsion is enough, but lid is difficult to be applied in, and lid may deform, and can not correctly be applied, and under a stable condition, may on bottle, protrude very high.

Summary of the invention

The objective of the invention is to improvement and be used for closed bottle, particularly be provided with the lid of the bottle of thread neck part.

Another purpose is to reduce the problem that may occur in the process of bottling, and particularly those can cause breaks in production circulation and/or difference to cover the problem of quality packing and selling.

The specific embodiment

Fig. 1 represents to be applicable to for example lid 1 of the open end of bottle of closed container.Lid 1 for example can obtain by compression moulding or injection-molded plastic.

Lid 1 comprises cup 2, and this cup is limited by rounded plane diapire 3 basically.Cup 2 also comprises skirt section 4, and this skirt section extends out from diapire 3, and can be approximately perpendicular to described wall.Skirt section 4 is provided with screw thread 5 in inside, this screw thread is suitable for engaging with the thread neck part 31 (Fig. 3) of bottle, and skirt section 4 externally can be limited by the surface 6 of annular knurl, so that the user is easier to hold on cup 2, screws off thereby it is spun on the bottle or from bottle.

On diapire 3, can be formed for holding the bearing of sealing member 7, sealing part 7 is suitable for abutting against on the end of bottleneck, escapes in the external environment condition with the material that prevents to be contained in the bottle.

Skirt section 6 is limited by skirt 8 in respect to the zone of diapire 3 in this skirt section, and tamper-evident ring 9 links together with skirt 8 removably.Tamper-evident ring 9 is limited with second edge 14 relative with this first edge 13 by first edge 13 of contiguous cup 2.When being spun on lid 1 on the bottle, first edge 13 limits this tamper-evident ring 9 at the top, and second edge 14 limits it in the bottom.First edge 13 is connected on the skirt 8 by otch 11 separated bridgewares (bridge) or engaging zones 10 by a plurality of, so that limit the line of rupture 12 that extends around whole first edge 13.

As shown in Figure 2, tamper-evident ring 9 comprises the side wall arrangement 15 that is inserted between first edge 13 and second edge 14.

Side wall arrangement 15 is provided with join domain 16 in inside, holding device extends out from this join domain, this holding device be suitable for be positioned at bottleneck on neck ring engage.This holding device can comprise a plurality of towards diapire 3 inclinations, also by sector 18 tongue pieces 17 separated from one another, or alternatively, a continuous tongue piece.

As an alternative, as among Fig. 2 with shown in the dotted line, tongue piece 17 can be arranged essentially parallel to bottom 3 or tilt towards second edge 14.

Tongue piece 17 can equidistantly be provided with along tamper-evident ring 9 angledly.

As an alternative, tongue piece 17 can not be the equidistant setting in angled ground.

Odd number or even number tongue piece 17 can be set.

Join domain 16 is defining the first area 19 that is inserted between the join domain 16 and first edge 13 on the side wall arrangement 15, and is inserted into the second area 20 between the join domain 16 and second edge 14.First area 19 comprises the wall portion 21 that reaches tamper-evident ring 9 outsides.Second area 20 defines an edge, and tongue piece 17 is drawn from the each several part on this edge.

In example shown in Figure 2, wall portion 21 is a frusto-conical, and the less base surface of this truncated cone is to first edge 13, and big base surface is to join domain 16.The structure of wall portion 21 is such, so that the diameter of tamper-evident ring 9 increases to join domain 16 from first edge 13.In particular, the inside diameter of the first area 19 of tamper-evident ring 9 is from being positioned near the first numerical value D1 first edge 13, changing near the second value D2 greater than D1 that is positioned at the join domain 16.

Tubular substantially part 22 extends out from the end of the wall portion 21 relative with first edge 13, and this part 22 is limited by outside face 23 and inside face 24.The transverse gage that is tubular part 22 substantially is substantially the same with the thickness of wall portion 21.Being tubular part 22 substantially is connected in the wall portion 21 at 25 places, edge.

Each tongue piece 17 links to each other with cylinder bodily form part 22 by sector parts 26, and is limited by substantially parallel each other end face 27 and bottom surface 28.The end face 29 that is arranged essentially parallel to outside face 23 links together the end face 27 and the bottom surface 28 of each tongue piece 17.The end face 29 of tongue piece 17 defines diameter D3 in the inboard of lid 1.

Join domain 16 is connected on the base 14 by the dip plane 30 that is frusto-conical substantially, and the less base surface of this truncated cone is to diapire 3.Dip plane 30 and second edge, 14 angulation α, so as when lid 1 to be applied to bottleneck as promoting part.In particular, the numerical value of angle [alpha] is about 70 °.

As an alternative, as shown in figure 13, join domain 16 is connected on the feather edge 14 by another surface 41, and this surface 41 is substantially perpendicular to second edge 14, and in this way, second area 20 has along whole length constant thickness S substantially.

Fig. 3-5 shows lid 1 is applied to three application stages on the bottleneck 31.Neck 31 is provided with screw thread 35 at the top, it is applicable to and is positioned at cup 2 in-to-in screw threads 5 and engages.Below screw thread 35, be provided with the neck ring 32 that is limited by first side 33 and second bottom surface 34.

Lid 1 leans against on the screw thread 35 at first, then is spun on the latter gradually.Because dip plane 30 defines an inner chamfer on second area 20, lid 1 can relatively easily be forced on neck 31.In fact this inner chamfer has reduced lid 1 has been positioned at risk on the neck 31 improperly.Simultaneously, the inclined-plane that is limited by dip plane 30 can reduce and form tamper-evident ring 9 needed quantity of plastics.In fact, dip plane 30 provides the cross section that is essentially trapezoidal for the second area 20 of tamper-evident ring 9, with as among Figure 10 with shown in the dotted line, be that second area inside is parallel to the situation that the surface of outside face 23 limits and compares, this trapezoid cross section has the scope that reduces.

By continuation lid is spun on the screw thread, the tamper-evident ring begins and neck ring 32 mutual actions.By dip plane 30 make on the inclined-plane that limits on the second area 20 can be softr between tamper-evident ring 9 and neck ring 32 and mutual action little by little.By contacting with first side 33 of neck ring 32, tongue piece 17 trends towards around join domain 16 rotations, thereby near the first area 19 of side wall arrangement 15.This rotation can be followed the increase of angle [alpha].Simultaneously, join domain 16 trends towards deforming, radial expansion, thus can cross neck ring 32.In this phase process, the first area 19 of side wall arrangement 15 is tending towards outwardly-bent, presents arching structure shown in Figure 4.

This structure of the first area 19 of side wall arrangement 15 is beneficial to the radial expansion of join domain 16.In fact, give prominence to the outside, part 21 plays the effect that promotes distortion, and makes first area 19 can present the structure of arching easilier, this be with first area 19 be the diameter that has and the cooresponding tubular situation of first edge, 13 diameters Comparatively speaking.

The structure of part 21 makes that bridgeware 10 can be more near the bottle axis, thus utilize be applied to cup 2 on be used for moment of torsion that its moment of torsion that screws off is equated, can obtain being released in the bigger power on the bridgeware 10.

Green phase continues screw capping 1 for bottle, and tongue piece 17 is crossed neck ring 32, and will himself place the below of second bottom surface 34.On this position, tongue piece 17 no longer with neck ring 32 mutual actions, and owing to make the elasticity of their material, they turn back to its undeformable structure, first area 19 too.This situation is shown in Fig. 5.

When the customer wants lid 1 when bottle removes, he holds knurled surface 6, so that screw off cup 2.In this way, tamper-evident ring 9 is near neck ring 32, and tongue piece 17 beginnings and second bottom surface, 34 mutual actions.In particular, the end face 27 of each tongue piece 17 leans against on second bottom surface 34 of neck ring 32, and this second bottom surface 34 prevents that as the backstop that is used for tongue piece 17 they are further along bottleneck 31 risings.The moment of torsion that the customer applied of lid outwarded winding makes tongue piece 17 rotate around join domain 16, so that as shown in Figure 6, reduces the amount of angle [alpha].Owing to be subjected to pointing to the power of diapire 3, wall portion 21 tends on cylinder bodily form wall 22 in line, thereby reduces its gradient.

If the customer continues the lid of outwarding winding, just as shown in Figure 7, bridgeware 10 will rupture, and cup 2 separates from tamper-evident ring 9, and this tamper-evident ring 9 is connected with bottleneck 31 maintenances.

As reference Fig. 2 was formerly disclosed, the size of the inside diameter D 3 that is limited by tongue piece 17 made the clearance G between the end face 29 of neck 31 and tongue piece 17 keep the state that is limited as shown in Figure 8.Owing to clearance G with owing to plastic deformation second area 20 and/or tongue piece 17, after cup 2 was removed from bottle, tamper-evident ring 9 was owing to gravity falls along neck 31, away from neck ring 32.As shown in Figure 9, after part consumes vial matter, when the customer is applied in cup 2 on the neck 31 once more, lean against the skirt 8 that tamper-evident ring 9 on the annular protruding portion 36 of drawing from the neck 31 of neck ring 32 belows is kept away from cup 2, this expression bottle was unlocked.In fact, even tamper-evident ring 9 contacts with cup 2, in case tamper-evident ring 9 has been released, it falls along neck 31 with regard to by gravity.In this way, can prevent the passive mistake of bottle interior material and the ignorant possibility of customer.

This character does not have in available best lid.

In fact, in this lid, tongue piece is flexible and is elastomeric that promptly they can be easy to deform.Thereby after first the unlatching, they contact with neck, in this way, so that the tamper-evident environmental protection is held in the lifting state with respect to annular protruding portion.

Figure 10 shows according to the tamper-evident ring 109 of replacing modification, and this tamper-evident ring is different from the tamper-evident ring 9 that is shown in Fig. 1 to 9, and this is because it lacks and is tubular part 22 basically.Wall portion 121 outstanding outside tamper-evident ring 109 is frusto-conical basically, and it is limited by first edge 13 at the top, and is limited by join domain 16 in the bottom.The less base surface of the frustum of a cone that is limited by wall portion 121 is to diapire 3, and is big so that the internal diameter of tamper-evident ring 109 becomes gradually from first edge 13 to join domain 16.

Tamper-evident ring 109 comprises the second area 120 that is externally limited by frusto-conical wall portion 39, this wall portion 39 is β with respect to the angle of inclination of knurled surface 6, in this way, the external diameter of second area 120 becomes big from join domain 16 beginnings to second edge 14.

Figure 12 shows the tamper-evident ring 309 that is provided with wall portion 321, and this wall portion 321 is roughly similar in appearance to the wall portion 121 that is shown in the tamper-evident ring 209 among Figure 10.

Tamper-evident ring 309 is with the difference of tamper-evident ring 209, the former comprises the second area 320 that is externally limited by another frusto-conical wall portion 40, this wall portion 40 is γ with respect to the angle of inclination of knurled surface 6, in this way, the external diameter of second area 320 reduces to second edge 14 from join domain 16 beginnings.

Figure 11 shows the tamper-evident ring 209 of replacing modification according to another, and wherein outwards outstanding wall portion 221 is configured to the arching shape, and is limited by first edge 13 at the top, is limited by join domain 16 in the bottom.

The part 121,221 and 321 that is shown in Figure 10 to 12 makes that the radial expansion of tamper-evident ring is more easy, makes it can be positioned at the below of neck ring.In fact, the part of outstanding sidewall is as the distortion initiator towards the lid outside, thereby makes the first area 19 of tamper-evident ring can present the arching shape easilier, and therefore helps the expansion of join domain 16.

In addition, have owing to dip plane 30 second area 20,120,320 that reduces thickness be pulled to neck ring 31 below the time easy deformation more, make that like this applying lid 1 required moment of torsion has further reduced.Even now, tongue piece 17 can be guaranteed and the tamper-evident ring can not be removed from neck 31.

In Figure 14, show cup 2 is being suitable for fracture when bottle removes, and keep being anchored on this class tamper-evident ring 409 on the cup 2 by bridgeware 37.In unshowned modification, replace single bridgeware, a plurality of bridgewares can be set.

Such tamper-evident is equipped with the atenuator region 38 that crosses the side wall arrangement 15 that is parallel to bottleneck, and when the customer removed lid, tamper-evident ring 9 was along this atenuator region fracture.

Because the bigger deformability of side wall arrangement, atenuator region can be very dark, and therefore is easy to rupture removing in the process of lid, and can not rupture applying in the process of lid.

On the other hand, in the stiff tamper-evident zone of prior art, atenuator region must be very shallow.As a result, if atenuator region crosses tongue piece, more difficult removing in the time of will occupying the situation that is inserted in the sector between the tongue piece than atenuator region so.

Therefore be necessary on two separated sectors of adjacent tongue piece, to form atenuator region.Machine of the prior art thereby needs can form the setting device of line of weakness in the desired location.

On the contrary, in lid according to the present invention, line of weakness can be formed at any position, no matter pass tongue piece or pass sector.

Because weakening region can be very dark,, will be easy to fracture removing in the phase process of lid.

This makes lid production machine of the prior art more to simplify, thereby needn't use complicated setting device.
