The present invention will now be more particularly described, by way of example, with reference to the accompanying drawings.
The example embodiments are described in sufficient detail to enable those of ordinary skill in the art to embody and implement the systems and processes herein described. It is important to understand that embodiments can be provided in many alternate forms and should not be construed as limited to the examples set forth herein.
Accordingly, while embodiment can be modified in various ways and take on various alternative forms, specific embodiments thereof are shown in the drawings and described in detail below as examples. There is no intent to limit to the particular forms disclosed. On the contrary, all modifications, equivalents, and alternatives falling within the scope of the appended claims should be included. Elements of the example embodiments are consistently denoted by the same reference numerals throughout the drawings and detailed description where appropriate.
Unless otherwise defined, all terms (including technical and scientific terms) used herein are to be interpreted as is customary in the art. It will be further understood that terms in common usage should also be interpreted as is customary in the relevant art and not in an idealized or overly formal sense unless expressly so defined herein.
In the following description, all orientational terms, such as upper, lower, radially and axially, are used in relation to the drawings and should not be interpreted as limiting on the invention.
Referring first to FIGS. 1 to 5 there is shown a one-piece, tamper-evident closure generally indicated 10.
The closure 10 comprises a generally annular base 15 and a disc-like lid 20.
The base 15 is non-detachably attachable to a container neck 50. The interior of the base 15 includes a generally annular retention (snap) bead 17 which engages under a corresponding bead 52 on the neck finish.
The base 15 and lid 20 are connected by a hinge arrangement 25. The hinge 25 comprises a pair of generally trapezoidal/truncated triangular flanking links 27, 29. Between the links 27, 29 is a central link 30 which comprises a pair of projections 32, 34. When the lid is opened the projections 32, 34 wedge/abut against each other to hold the lid in a stable open position.
The lid 20 includes a generally disc-shape top plate 21 and a sidewall 22 which depends from the top plate, slightly inboard of its periphery (so that it resembles an upturned top hat). An annular plug 23 depends from the underside of the top plate 21 and in use seals in the bore of the container neck.
The sidewall 22 extends from the hinge links 27, 29 around towards the “front” of the lid, opposite the hinge 25. Between the two ends of the sidewall a lifting strap 35 is provided.
The strap 35 is a generally hyoid shape, with two axial strap portions 36, 37 and a central bight 38. The strap 35 has a central gap/aperture/window 39.
In the unopened condition (see FIG. 1, for example) a tamper-evident tab 40 is frangibly connected to the lid sidewall within the window 39 by frangible bridges 42.
The base 15 is provided with a retaining ledge 18. The ledge 18 is positioned so that the “top” of the bight 38 engages thereunder when the lid is closed.
The tamper-evident tab 40 includes a hook 41 which engages under a corresponding hook 19 on the ledge 18.
In use, when the lid is opened for the first time the lifting strap 35 is lifted (using the bight 38, the centre of which is formed like a jutting chin). The tab 40 cannot move upwards because of the hooks 41, 19, so this causes the bridges 42 to break. The tab 40 falls down and therefore fall out of the window (see FIG. 2, for example). This provides visual evidence that the lid has been opened at least once.
FIGS. 6 to 12 show a closure 110 formed according to a further aspect of the present invention. The closure 110 is formed as a one-piece, non-detachable snap-on closure.
The closure 110 comprises a generally annular base 115 and a disc-like lid 120.
The base 115 is non-detachably attachable to a container neck 150. The interior of the base 115 includes a generally annular retention (snap) bead 117 which engages under a corresponding bead 152 on the neck finish.
The base 115 and lid 120 are connected by a hinge arrangement 125. The hinge 125 comprises a pair of generally trapezoidal/truncated triangular flanking links 127, 129 which connect to the base and the lid.
Between the links 127, 129 the top plate 121 of the lid is provided with a tab extension 126 and the base is provided with a corresponding upstanding tab extension 128. When the lid is opened the extensions 126, 128 wedge/abut against each other to hold the lid in a stable open position (see FIGS. 7 and 9, for example).
The lid 120 includes a generally disc-shape top plate 121 and a sidewall 122 which depends from the top plate, slightly inboard of its periphery (so that it resembles an upturned top hat). An annular plug 123 depends from the underside of the top plate 121 and in use seals in the bore of the container neck.
Opposite the hinge 125 a lifting strap 135 is provided. The strap 135 is a generally hyoid shape, with two axial strap portions 136, 137 and a central bight 138.
The interior of the bight 138 is provided with a bead 155 which engages under the container neck rim 154. This engagement provides a strong retention force, preventing the lid from being accidentally lifted.
FIGS. 13 and 14 show a closure 210 formed according to a further embodiment. The closure 210 is similar to the closure 110.
In this embodiment the base 215 includes a frontal cut-out 216 in which a strap bight 238 sits. This means that a bight retaining projection 255 can engage under a neck bead 253 (rather than under the rim) to hold the lid closed. In this embodiment, at the split line between the base and the lid they are joined by a plurality of frangible bridges 260.
The bight 238 is joined to the straps 236, 237 by thinned lines 265, 267 and the bight is joined to the lid sidewall 222 by a thinned line 269. This means that the bight 238 can be hinged outwards to allow the projection 255 to pass over the bead 253.
FIGS. 15 to 19 show a tamper-evident closure 310 formed according to a further aspect of the present invention.
The closure 310 comprises a base 315 and a lid 320. The base and lid are connected by a hinge 325.
The base 315 is generally annular and is non-detachably attachable to a container neck 350. The interior of the base 315 includes a generally annular retention (snap) bead 317 which engages under a corresponding bead 352 on the neck finish.
The lid 320 comprises a disc-shape top plate 321 and a sidewall 322 that depends from the periphery thereof.
At the “front” of the lid 320, generally opposite the hinge 325, the sidewall 322 includes a cut-out 324 that extends from the free end of the sidewall. Axially above (i.e. closer to the top plate 321) the sidewall includes a window 340. The cut-out 324 and window 340 are separated by a bar 343.
A tamper-evident lifting member 370 is provided. The member 370 comprises a lower peak 372 and an upper hook 374 joined together by an intermediate portion 376. In the unopened condition the peak 372 is frangibly connected to the base by frangible bridges 378. The lid sidewall includes a recessed portion 380 which has a hook 382. In this embodiment the portion 380 sits on top of the neck rim 384. In the unopened condition the upper hook 374 sits above the bar 343 and below the hook 382 and is visible in the window 340.
In use, the lid is opened by lifting the member 370 using the peak 372. This causes the bridges 378 to break and the member moves axially towards the top plate 321. The member hook 374 moves over and engages above the sidewall hook 382, which prevents it from moving back down. Continued lifting of the member 370 now lifts the lid. The position of the member 370 with respect to the cut-out 324 and the window 340 provides visual evidence of opening of the lid.
FIGS. 20 to 30 show a closure 410 formed in accordance with a further aspect of the present invention.
The closure 410 comprises a generally annular base 415 and a disc-like lid 420.
The base 415 is non-detachably attachable to a container neck 450. The interior of part of the base 415 includes a generally annular retention (snap) bead 417 which engages under a corresponding bead 452 on the neck finish.
The lid 420 includes a generally disc-shape top plate 421 and a sidewall 422 which depends from the top plate, slightly inboard of its periphery (so that it resembles an upturned top hat). An annular plug 423 depends from the underside of the top plate 421 and in use seals in the bore of the container neck.
The base 415 and lid 420 are connected by a hinge arrangement 425. The hinge 425 comprises a pair of generally trapezoidal/truncated triangular flanking links 427, 429 which connect to the base and the lid.
Between the links 427, 429 the top plate 421 of the lid is provided with a tab extension 426 and the base is provided with a corresponding upstanding tab extension 428. When the lid is opened the extensions 426, 428 wedge/abut against each other to hold the lid in a stable open position (see FIGS. 29 and 30, for example).
The sidewall 422 extends from the hinge links 427, 429 around to the “front” of the lid, opposite the hinge 425. A lifting strap 435 is provided. The strap 435 is a generally hyoid shape, with two axial strap portions 436, 437 and a central bight 438. The strap 435 defines a gap/aperture/window 439. The upper surface of the bight 438 is flat and engages under the neck bead 453. The base includes a frontal cut-out 490 that is shaped to correspond with the bight 438.
A tamper-evident member 480 is provided. The member 480 comprises a double ring structure, with an upper 482 and lower 484 ring which are frangibly connected together. The upper ring 482 has a hook 483 which extends radially outwards. The lower ring 484 has a hook 485 which extends radially inwards. The lid sidewall includes a retention bead 486. The upper ring hook 483 engages over the bead 486 to retain the ring 482. The lower ring hook 485 engages under the neck rim 454.
The closure is shown unopened in FIGS. 20, 21, 23 and 24. The lid cannot be lifted because of the engagement of the flat upper face 492 of the bight under the bead 452. In order to open the lid the strap 435 must be bent/pivoted from under the bead, as illustrated in FIG. 25. This causes the rings 482, 484 to be broken apart (FIG. 26). The lid can be pivoted over, in this embodiment by 270 degrees (FIGS. 29 and 30). The tabs 426, 428 engages to provide a stable open position.
When the lid is reclosed the inclined face 487 of the bight 483 allows it to pass over the bead 452 (FIG. 27). The upper ring is retained in the lid. The lower ring has dropped down onto the neck bead 452 and is visible through the window 439 (FIGS. 22, 27 and 28) to serve as visual evidence that the lid has been opened.
FIGS. 31 to 39 show a closure 510 formed according to a further embodiment. The closure 510 is similar to the closure 410. In this embodiment the lower ring hook 585 extends radially inwards with a flat upper surface (as opposed to extending radially inwards and upwards towards the top plate as with the hook 485).
FIGS. 32, 34 and 36 show the closure unopened. FIGS. 33, 35 and 37 show the closure following opening. The lower ring 584 has dropped down and is visible through the window 539.
In this embodiment the hinge arrangement provides a stable open position at approximately 180 degrees (FIGS. 38 and 39).
FIGS. 40 to 45 show a closure 610 formed according to a further embodiment. The closure 610 is similar to the closures 410, 510. In this embodiment the lower ring hook 685 extends radially inwards with a flat upper surface. The upper ring is formed with a chicane-like section.
In this embodiment, in the unopened condition the lower ring is visible. Upon first opening the lower ring drops onto the neck bead and is no longer visible, whereby to indicate opening. FIGS. 46 and 47 show a closure 710 formed according to a further embodiment. The closure 710 is similar to the closures 410, 510, 610, with a double ring tamper-evident member. The upper ring 784 drops to become visible upon first opening.
FIGS. 48 to 55 show a closure 810 formed according to a further embodiment. The closure 810 is similar to the closures 410, 510, 610.
In some aspects and embodiments a standard neck finish is used. In other embodiments a bespoke neck finish is used.
