Description

Improvements in or about closures

technical field

The present invention generally relates to a closure, such as a dispensing closure. In some aspects and embodiments, the present invention relates to a dispensing closure, such as a "sport cap," wherein a user can drink directly through a portion of the closure.

Background technique

It is known to provide a dispensing closure for use eg in combination with beverages such as mineral water, sports drinks and the like. Typically, these closures are provided as a base with a drinking tube and a lid hinged to the base so that the lid can be flipped from a closed position in which the drinking tube is protected to an open position in which the drinking tube is protected. In the open position, the drinking tube is accessible so that a user can drink from the drinking tube.

One consideration for such a closure is to ensure that it is as convenient as possible for the user to drink through the drinking tube. For example, in many known closures, when the lid is moved to the open position, the hinge arrangement tends to pull the lid back towards the closed position and thus interferes with the user's mouth during drinking.

Contents of the invention

The present invention seeks to provide improvements over known closures.

According to an aspect of the invention, there is provided a closure comprising a base and a lid, the base and lid being joined together by hinge means so that the lid can move between a closed position and an open position, so that The hinge means includes one or more links for connecting the base and lid, and the closure includes a deformable section that deforms and applies force when the lid is moved to the open position. on the link so as to apply pressure to said link and hold the lid securely in the open position.

This aspect of the invention thus provides a firm open position which prevents the cover from passively returning to the closed position and thus prevents the cover from interfering with any activity taking place in or around the base.

The deformable section may be provided on or by the cover.

The hinge may comprise a plurality of links, and the deformable section may act on an intermediate link of the hinge. For example, two links may be provided and the deformable section acts in the middle of the two links. Embodiments are possible in which more than three links are provided and also embodiments in which more than one deformable section each acts, for example, on one or more links.

The base can deform the deformable section. In other words, when the lid is moved towards the open position, the base contacts the deformable section and said deformable section deforms so as to exert stress on the link when the open position is reached.

The deformable section may form part of the hinge arrangement. Alternatively, the sections may be separate from the articulation means but adapted to interact with the articulation means.

The hinge arrangement may comprise two or more joints spaced apart from each other. As discussed above, arrangements with three or more linkages are possible.

The connecting piece or each connecting piece may be in the shape of a belt as a whole. A relatively thin plate-like strip is used to provide the bond and is relatively susceptible to stress.

The link can be extended in the open position. In other embodiments, tension or torsion may be applied to stress the link when in the open position.

The deformable section may be adjacent to the base. In some embodiments, the deformable section is integral with the base; however, in other embodiments, a separate break, such as a gap or thinned material, is provided between the deformable section and the base.

The deformable section is movable between generally convex and concave configurations in closed and open positions. For example, the segment may flip between two such curved configurations.

The deformable section may form part of the side wall of the lid. For example, the section may be arranged at or around the free end of the edge portion.

The closure may be formed as a dispensing closure, such as a flip-top dispensing closure. For example, the closure may comprise a drinking tube which may for example form part of the base or may be formed as a separate part which is integrated with the base. The cap may include a plug for use in conjunction with a drinking tube.

The base may include coupling means for connecting the closure to the container. For example, threading and/or snap-fit arrangements may be provided. In addition or as an alternative, a tamper-evident device can be provided. For example, a tamper-evident strip may be provided at the open end of the base.

When the cover is in the open position, it can move at least 180 degrees from the base. For example, the lid can move at least 180 degrees between the closed and open positions, or the lid can be oriented relative to the base so that after movement (the movement can be less than 180 degrees), the open position provides at least 180 degrees between the base and the lid clearance.

The closure may also include a second hinge for joining the lid relative to the base. The second hinge may operate independently of the first hinge; alternatively, the first and second hinges may cooperate. The second hinge may be curved, or may be straight.

The cover may have a generally frusto-conical shape, wherein the side edge portions taper into a cone.

The present invention additionally or alternatively relates to a closure for a container, and in particular to a closure capable of providing some indication that the closure has been opened at least once.

It is known to provide a tamper-evident tab which can be released from the open end of the side wall of the closure upon first opening. Although the drop band provides some indication that the closure has been opened, because of its physical separation there is no clear indication of opening the rest of the closure. It is also known to provide a tear-off (peel-off) strip which is removed from the closure body upon first opening. However, the tear-off strip presents a mess problem and a potential risk of jamming because it is usually a small tab that is separate from the closure body.

The present invention seeks to solve the problems of known tamper evident closures.

In other aspects, the present invention provides a tamper-evident closure comprising a base, a lid, a dispensing member and a tamper-evident member that, during use, The closure is visible before opening and becomes at least partially hidden from view when the closure is opened for the first time, wherein the tamper-evident member conceals at least a portion of the dispensing member prior to opening the closure for the first time during use, and At least a portion of the dispensing member is revealed upon opening the closure for the first time so as to indicate that the closure has been opened at least once.

In one embodiment, the base may at least partially define a void, and upon first opening the closure, the tamper evident member may be at least partially moved into the void.

The base and cover may be integrally hinged to each other so that they are manufactured in one piece. For example, the closure could be manufactured from plastic and the base and lid could be molded in one piece and connected together via hinge means. The hinge may be a snap-type hinge and may include at least one strap.

The dispensing member may be a separate member from the cover and/or base. For example, the dispensing member may be molded separately, as opposed to the lid and/or base being integral. The dispensing member can then be assembled with the cover and/or base. The dispensing member may be a drinking tube for drinking directly therefrom or for pouring. Alternatively, the dispensing member may be integrated with the cover or base.

The tamper evident member is movable from an unarmed position to an armed position. This movement occurs during assembly of the dispensing member and base.

The tamper-evident member may be frangibly connected to the base and/or lid, and the frangible breakable connection or connections may be compromised when the closure is opened for the first time. For example, the tamper-evident member may be releasably connected to the cover at one end. At the opposite end, a protrusion may be provided. Such a protrusion may be combined with the base and/or the dispensing member such that when the closure is first opened, the tamper-evident member cannot follow the relative movement of the lid such that the breakable connection(s) are damaged. Alternatively or additionally, the tamper-evident member can be breakably connected to the base at one end and the extension can be combined with the cover so that the act of opening the cover for the first time causes the breakable connection (multiple Breakable connector) fracture effect.

The tamper-evident member may be separate from the base, lid and dispensing member, and the closure and tamper-evident member may include corresponding means for limiting their relative movement when first opened. For example, the tamper evident member may be in the form of two rings connected together by a breakable link(s). Such a ring may fit between the cover and the base and surround the dispensing member. The lid and drinking tube or base may include protrusions that engage corresponding protrusions on the tamper-evident member such that when the closure is opened for the first time, the tamper-evident strip is pulled apart so that the lid Pull one loop and the base or drinking tube pulls the other loop. The breakable connection(s) may then be broken such that the tamper evident member splits into two parts. The lower ring of the tamper-evident member may drop into a pocket or void provided in the base so as to be at least partially hidden from view and to at least partially reveal the dispensing member.

The color of the dispensing member may be different from that of the lid and/or base so that the dispensing member can be seen more clearly when the tamper-evident member is moved when opening for the first time.

More than one tamper evident member may be provided.

In other aspects, the present invention provides a tamper-evident closure comprising a closure body and a tamper-evident member for first opening the closure during use wherein the tamper-evident member is at least partially hidden from view when the closure is opened for the first time, thereby indicating that the closure has been opened at least once.

Thus, while the tamper-evident member of the closure remains on first opening, it becomes at least partially hidden from view when the indicator indicates that the closure has been opened at least once. In some embodiments the tamper evident member may be completely hidden from view.

In other aspects, the present invention provides a tamper-evident closure comprising: a closure body defining a void; and a tamper-evident member which, during use, The tamper-evident member is visible on a single opening of the closure, wherein the tamper-evident member is at least partially moved into the clearance on first opening of the closure, thereby indicating that the closure has been opened at least once.

A tamper-evident member formed in accordance with the present invention may be releasably connected to the closure body. The tamper-evident member can thereby be released from the body when the closure is opened for the first time.

The closure body may include an open-indicating section, and the tamper-evident member may include a cover that reveals the open-indicating section when the closure is opened for the first time.

The section indicating opening may include other sections or components of the closure, such as a drinking tube.

The opening-indicating section may be formed so as to be highly visible, so that once after moving the tamper-evident member, there is presented clear evidence that the closure has been opened at least once.

The color and/or texture of the opening-indicating section contrasts sharply with the color and/or texture of other components of the closure to increase visibility.

The closure may comprise a window in or through which the tamper-evident member is visible prior to opening the closure for the first time. Thus, when the closure is opened for the first time, the tamper-evident member can fall out of the window or become misaligned with the window.

The tamper-evident member may be moved from an unarmed position to an armed position, for example, the closure may comprise multiple parts and the tamper-evident member may only be moved to the armed position when the closure parts are assembled together. In other words, the tamper evident system is only actuated upon assembly.

The closure body may comprise multiple components. For example, the closure body may comprise a first part and a second part such as a base and a lid, which may be hingedly connected together.

The closure may include a drinking tube portion through which the contents of the associated container can be dispensed. In one embodiment, the closure comprises a base portion connected to the lid by hinge means, and a drinking tube portion received internally by the base/lid.

The closure may be formed from any suitable material, such as plastic or metal material. Different parts of the closure may be formed from different materials.

In other aspects, the invention relates generally to a closure and in particular to a closure comprising a body portion and an insert portion.

It is known to provide a closure having two or more parts, such as a body and a drinking tube. In many cases, foreign fluids must be applied to such closures. For example, cooling or cleaning fluid is sprayed onto the closure during the manufacturing process.

It is difficult to produce a closure that reliably prevents the ingress of water between the body and the various components of the insert. The result is that fluid can become trapped within the closure, which is undesirable.

The present invention seeks to solve the problems of known closures.

According to a further aspect of the invention there is provided a closure comprising a body and an insert and having a vent system for allowing fluid applied to the closure to pass between the exterior of the insert and the interior of the body to allow Remove the fluid.

The vent system may include one or more vent paths formed at the interface between the insert and the body.

The discharge path(s) may be wholly or partially formed in either one or both of the body and the insert.

The or each vent path may comprise one or more slots formed at the periphery of the insert.

The insert may include a plurality of ribs or radial projections at its periphery. Slots may be formed between the ribs.

The slot(s) may include sloped discharge surfaces to facilitate drainage.

The insert may include a plurality of spaced apart retention barriers. The obstruction may at least partially define a discharge path.

The insert may comprise a drinking tube. For example, a drinking tube would need to be sanitized with a cleaning fluid, and then the fluid would need to be removed so as not to affect the user's taste.

The body can include a base and a cover. The base and lid may be joined by a hinge, such as a follow-through type hinge. The interface between the cover and base is a likely location where fluid will enter.

According to a further aspect, there is provided an insert for a closure body, the insert comprising one or more drain paths for allowing fluid applied to the closure to pass between the exterior of the insert and the interior of the body so that Allow the fluid to be removed.

Among other aspects, the present invention relates generally to a closure, and in particular to a known type of closure such as a sports cap.

Recently, the use of sports caps has been increasing. Sports caps differ from the more traditional so-called integral caps in that they have two sealing areas: 1) the sealing area between the closure and the neck of the container (which integral caps have); ii ) the sealing area between two parts of a closure. The two parts of the closure may comprise eg a drinking tube and a lid or a push-pull drinking tube and a base.

Hot filling is a filling method with which containers are filled with product at relatively hot processing temperatures in order to ensure continuous sterilization of containers and product during or after the filling process. When capping such containers, the closure must be suitable for the application.

It is known to provide a closure having two or more parts, such as a body or a drinking tube. In many cases, external fluid must be applied to the closure. For example, cooling or cleaning fluids are sprayed onto the closure during the manufacturing process. It is difficult to produce a closure that reliably prevents the ingress of water between the body and the various components of the insert. The result is that fluid can be trapped within the closure, which is undesirable.

The present invention seeks to solve the problems associated with known kinematic lid closures.

According to other aspects of the present invention, there is provided a linerless, thermally charged sports lid closure.

According to other aspects of the present invention, there is provided a closure for a thermally charged sports cover, the closure comprising a body having two or more components and two or more sealing areas, the first sealing One region can be closed to the container neck, while the second sealing region is located between the two body parts.

According to a further aspect of the invention, there is provided a thermally charged sports lid closure comprising a body which does not form a sealing gasket but has a base with a drinking tube and a lid for sealing drinking tube.

The closure may be a one-piece integral closure. For example, the base could be formed with an integral drinking tube and an integrally formed lid could be provided.

Alternatively, the closure may be formed from two or more separate parts. For example, a closure may include a body and an insert. The closure may have a drain system for allowing fluid applied to the closure to pass between the exterior of the insert and the interior of the body to allow removal of the fluid.

The closure may include a body and an insert, and have a drain system for allowing fluid applied to the closure to pass between the exterior of the insert and the interior of the body to allow removal of the fluid.

By providing a venting system, the closure is particularly, though not exclusively, suitable for hot charging applications where the closure is typically sprayed after capping for cooling and/or sterilization purposes.

Detailed ways

Referring first to Figures 1 to 3, there is shown a closure generally indicated by the reference numeral 10, which is connectable to a container neck (not shown). The closure 10 comprises a translucent body 11 and a drinking tube insert 20 .

The main body 11 includes a base 12 and a cover 14 .

Base 12 includes a generally cylindrical side wall 16 having at one end a tamper-evident annular band 17 connected to the base by a plurality of breakable bridges 18. Described side wall 16.

The side wall 16 terminates at its end opposite the band 17 with an annular shoulder 16c extending radially inwards.

The generally tower-shaped cover 14 is connected to the free end of the shoulder 16c via hinge means, indicated generally at 32 .

The interior of the base side wall 16 includes internal thread formations 16a for engaging corresponding external thread formations on the container neck. The interior of the side wall 16 also includes an annular retaining rib 16b.

The interior of the strap 17 includes segmented retaining ribs 17a for engaging under locking ribs on the container neck so that the strap 17 will remain on the container neck if the closure is unscrewed.

The lid 14 includes a top plate 34 from which lid side walls 35 depend; a plug 36 depends from the underside of the lid's center.

Opposite the hinge means 32, the lid 14 includes a small protrusion 38 for lifting the lid relative to the base 12 and for flipping the lid open.

Drinking tube 20 includes a generally cylindrical lower portion 50 , a generally cylindrical central portion 51 and a generally frusto-conical upper portion 52 .

The lower portion 50 includes an annular outer sealing bead 56 . In use, portion 50 enters the hole in the neck of the container such that sealing bead 56 seals against the inner surface of said hole.

The central retaining portion 51 includes a plurality of radially outwardly extending retaining spokes 60 .

Upper portion 52 includes a curved, generally frusto-conical outer surface that defines a drinking tube. A cylindrical end portion 70 is located at the end of the side wall of the drinking tube opposite the central portion 51 . A sloped annular hole wall 72 extends inwardly from the free end of portion 70 and an annular wall 73 depends from said sloped annular hole wall 72 ; wall 73 defines hole 74 .

A drinking tube 20 is received into the body 11 . Retaining spokes 60 engage the retaining ribs 16b to securely hold the drinking tube in place. Plug 36 extends through arm 73 to close hole 74 .

With the insert 20 in place, slots are formed between the spokes 60 of the central portion 51 and the side walls 16 , as shown in FIG. 9 .

As illustrated in FIG. 8 , if fluid is splashed on the closure 10 , the fluid will enter the interior of the closure through the hinge line interface between the lid 14 and base 12 . If this happens, fluid can pass between the spokes 60 and then between the closure and container threads and out at the bottom of the side wall 16 . This means that there is an unobstructed discharge path A for fluid to flow as it flows into the closure. The fluid must be forced through the discharge path, for example by blowing air at the closure.

The articulation device 32 is described in more detail below with reference to FIGS. 13 to 36 . The hinge arrangement 32 allows the lid 14 to be held securely in the open position approximately 180 degrees from the closed position.

A tamper-evident member 1 for the closure is provided and is shown in more detail in FIG. 7 .

The member 1 is in the form of a separate element having an upper ring 2 and a lower ring 3 connected together by a breakable connection, and said member 1 is assembled with a closure 10 . When assembled, the tamper-evident member 1 fits between the base and lid and radially outwards from the drinking tube 12 . The tamper-evident member 1 has an upper projection 4 protruding radially inward at the upper ring 2 and a lower flange 5 on the lower ring, which protrudes radially outward.

When the tamper-evident member 1 is assembled with the closure 10, the upper projection 4 is combined with the projection 25e provided on the radially inner surface of the side edge portion 25b of the cap. Furthermore, the flange 5 engages the underside of the shoulder 16c on the drinking tube 20 . In this way, when the lid is first closed, said lid cannot be opened without breaking the breakable link. Thus, as shown in FIGS. 4 to 6 , 9 and 10 , the component 1 is divided into two rings 2 , 3 and the lower ring 3 is no longer visible through the cover window, said lower ring 3 falling into the drinking tube holder-like protrusion 21 In the gap 7 above.

In Figures 1 to 3, the closure 10 is shown in the closed position. When the user wishes to drink from the drinking tube, they grasp the lid and use the protrusion to flip the lid open.

The user now has free access to the drinking tube and is not hindered by the cap. In case the lid is in the open position, the projection 25e holds the ring 3 in the lid and allows said ring 3 to be clearly seen.

The lid can be returned to the closed position by overcoming the forces present in the panel sections and linkages (see below). The articulation returns to its original stress-free state, ready to open again when required. Separated rings 2, 3 indicate that the closure has been opened at least once, as shown in FIGS. 4 to 6 .

Hinge features of the general type used with the closures of FIGS. 1-12 are now described in detail with respect to a closure 110 formed according to the alternative aspect shown in FIGS. 13-36 .

Referring first to Figures 13 to 23, there is shown a closure, generally indicated at 110, attached to the neck 105 of the container. As shown in FIGS. 4 , 10 and 11 , the closure 10 includes a main body 111 , a drinking tube 120 and a self-closing valve assembly 125 .

The main body 111 includes a base 112 and a cover 114 .

Base 112 includes a generally cylindrical side wall 116 having at one end a tamper-evident annular ring 117 connected thereto by a plurality of breakable bridges 118 .

The side wall 116 is terminated at its end opposite the band 117 by an annular shoulder 116c extending radially inwards.

The generally tower-shaped cover 114 is connected to the free end of the shoulder 116c by hinge means, generally indicated at 132 .

The interior of the base side wall 116 includes internal thread formations 116a for engaging corresponding external thread formations on the container neck. The interior of the side wall 116 also includes an annular retaining rib 116b.

The interior of the strap 117 includes an annular retaining rib 117a for engaging under the locking rib 106 on the container neck 105 so that the strap will remain on the container neck if the closure is unscrewed.

Cover 114 includes a top plate 134 from which cover sidewalls 135 depend; a plug 136 depends from the underside of the cover's center.

Opposite the hinge means 132, the lid 114 includes a small protrusion 138 for lifting the lid relative to the base 112 and flipping said lid open.

Drinking tube 120 includes a generally cylindrical lower portion 150 , a generally cylindrical central portion 151 and a generally frusto-conical upper portion 152 .

The lower portion 150 includes an annular outer sealing bead 156 . In use, the seal 154 enters the bore in the neck of the container such that the sealing bead 156 seals against its inner surface.

The central retaining portion 151 includes a plurality of radially outwardly extending retaining spokes 160 .

Upper portion 152 includes a curved, generally frusto-conical outer surface that defines a drinking tube. A cylindrical end portion 170 is located at the end of the side wall of the drinking tube opposite the central portion 151 . An annular aperture wall 172 extends inwardly from the free end of portion 170 and defines aperture 174 . Wall 172 includes a depending annular protrusion 173 . An annular retaining rib 176 depends internally from the base of the end portion.

Self-closing valve assembly 125 includes a body 126 and a valve 127 . Such a structure is known from the Applicant's International Patent Application No PCT/EP2005/053917. The valve body 125 includes a retaining rib 128 which clips onto the drinking tube retaining rib. Valve assembly 125 is received between retaining rib 176 and annular wall extension 173 .

Drinking tube 120 is received into body 115 . Retaining spokes 160 bond to retaining ribs 116b so that the drinking tube is held securely in place. Plug 136 enters hole 174 .

With the insert 120 in place, slots are formed between the spokes 160 of the central portion 151 and the side walls 116 .

If fluid is splashed on the closure 110, the fluid will pass through the hinge line interface between the lid 114 and the base 112 into the interior of the closure. If this happens, fluid can pass between the spokes/ribs 160 and then between the closure and container threads and out at the bottom of the sidewall 116 . This means that there is an unobstructed drain path for fluid to flow as it flows into the closure. The fluid must be forced through the discharge path, for example by blowing air at the closure.

Hinge arrangement 132 includes a pair of generally trapezoidal straps 180 , 182 that join the base to a generally trapezoidal hinge plate 184 . Between the straps 180 , 182 , the base includes elongated trapezoidal uprights 186 and the plate 184 includes mirror-image deformable projections/regions/sections 188 . Projections 186, 188 are separated by a gap 190, which has a thus formed generally dumbbell-shaped configuration with generally triangular openings 191, 192 bounded by a thin rectangular opening 193. connect.

At the opposite end of the hinge plate 184 , a generally straight line of material thinning 195 provides a secondary hinge line 195 .

In FIGS. 21-23 , the housing 110 is shown in a closed position. When the user wishes to drink from the drinking tube, they grasp the lid and use the protrusion to flip the lid open.

In FIGS. 24 to 27 the cover is shown in an intermediate position in which the cover has been rotated approximately 140 degrees away from the base. The lid is joined relative to the base by joints 180,182. In the position shown, the hinge plate extension 188 area (shown most fully in FIG. 19 ) comes into contact with the shoulder of the cover.

In Figures 28 to 31 the cover is shown rotated a further approximately 160 degrees. Plate 184 begins to rotate onto the shoulders.

At approximately 170 degrees, the plate extension 188 deforms from the seat with an accompanying click when flipping/snapping from the generally convex configuration to the concave configuration.

In Figures 32 to 36 the closure is shown fully open. Plate extension 188 has deformed and transitioned from a generally convex configuration to a generally concave configuration. Deformation of the plate section 188 puts the straps 180, 182 under stress and this holds the lid in the open position. Note that the fully open position is facilitated by the secondary articulation means 195, which allows further articulation of the cover than would be the case with the straps 180, 182 alone.

The user now has free access to the drinking tube without being hindered by the cap.

The lid can be returned to the closed position by overcoming the forces present in the panel sections and the link. The articulation returns to its original unstressed state, ready to open again when required.

The tamper evident features suitable for use with the closures of the present invention, such as in Figures 1 to 12 and Figures 13 to 36, are now described in more detail with reference to different closures.

Referring first to Figure 37, there is shown a tamper evident closure generally indicated by the reference numeral 210. The closure 210 is intended to be attached to the neck 215 of the container.

The closure 210 includes a base 220 and a cover 225 which together comprise a closure body. Cover 225 is connected to base 220 by hinge means 226 .

The base 220 includes a cylindrical edge portion 220a opened at both ends. At the end of the rim portion 220a adjacent the cover 225, a flange 224, or a top or upper surface 224 of the base 220, extends radially inwardly.

The cover 225 includes an upturned cup having a top plate 225a and side edge portions 225b depending from the outer periphery of the top plate 225a.

Edge portion 225b is coaxial and concentric with base edge portion 220a. Flange 224 reduces the radius of base 220 to match the cover. Accordingly, flange 224 includes an inward step.

The base 220 is provided with an anti-tamper tab 230 . The tab 230 is shown in an upright position in which it is aligned with a window 227 formed as a cut-out at the base of the lid edge portion 225b.

Tab 230 is positioned at the mouth of pocket 231 formed in flange 224 . Tab 230 is held in place by two breakable bridges (not shown). One bridge connects the tab 230 to the base 220 , while the other bridge connects the tab to the cover 225 .

To open the closure 210, the lid 225 is hinged to a position shown in FIG. 38 remote from the base 220. As shown in FIG. When the lid is moved, the two breakable bridges break. The tab 230 is released into the pocket 231 where it remains as shown in FIG. 38 .

When the cover 225 is returned to the closed position as shown in Figures 39 and 40, the window 227 of the cover 225 is no longer covered by the tab 230, because the tab is hidden from view and thus provides an indication that the closure has been opened. Visible evidence.

Closure 210 may include a dispensing member (not shown), which is visible through window 227 .

Referring now to FIG. 41 , a closure 310 according to a second embodiment is shown.

The closure 310 includes a base 320 and a cover 325 joined together by hinge means (see Figures 47-49). The base and lid together comprise a closure body.

The base 320 includes a generally cylindrical edge portion 320a having an internal thread structure 321 and a retaining rib 322 formed on the inner surface.

At one end of the base edge portion 320a, a tamper-evident drop strap 323 is provided. The band 323 comprises an annular strip 323a having an upturned annular flap 323b formed at its free edge portion to engage under the retaining rib of the container. The strap 323a is connected to the lower end of the base 320 by a breakable bridge 323c. At the other end of the edge portion 320a, a flange 324 extends radially inwardly to form a shoulder.

The cover 325 includes a top plate 325a and side edge portions 325b that hang down from the outer periphery of the top plate 325a. A sealing plug 325c is formed on the lower side of the top plate 325a. At the open end of the edge portion 325b, two diametrically opposite tamper-evident tabs 330 are provided. Tab 330 is formed in window 327 at the lower end of edge portion 320a and is disconnectably connected to window 327 by bridge 332, as best shown in FIG.

The tab 330 is generally L-shaped in cross-section and includes a main plate 330a to which a breakable bridge 332 is centrally connected and an undercut leg portion 331 .

Flange 324 is formed with two diametrically opposed cut-outs 324a that align with tabs 330 as best shown in FIG. 46 .

The closure 310 is shown as it is molded (ie it is molded in the closed position) with the hinge means holding the lid 325 on the base 320 (see Figures 47 and 48). Thus, the tab 330 is effectively suspended from the window 327 by the bridge 332 . The relative size of the tab 330 and the recess 324b of the flange 324 means that in the as-molded state, if the lid 325 is hinged away from the base 320, the tab 330 will pass through the recess 324 without breaking off.

The closure 310 also includes a drinking tube section generally indicated at 340 . Drinking tube section 340 includes a frustoconical boss 341 defining a bore 341a and joined to base section 342 and shoulder 342a. A retaining hook 343 extends laterally from the base 342 . A sealing lip 344 depends from the free end of the base 342 and is intended to seal in a bore (not shown) in the neck of the container.

Referring now to FIGS. 42 and 43 , the closure 310 is shown in a partially assembled position.

The drinking tube 340 is introduced into the interior of the closure 310 through the base edge 320a to the position shown in FIG. 42 . It should be noted that the upper side of the rib 343 of the drinking tube 340 engages the underside of the rib 322 of the base 320 . Also, the plug 325c begins to enter the hole 341a of the nipple 341 .

It should also be noted that rounded shoulder 342a of drinking tube 340 engages tab 330 at the intersection of main plate 330a and leg portion 331 .

Referring now to FIGS. 44-47 , the drinking tube 340 is shown maximally inserted into the closure body. Continuous insertion of the drinking tube 340 means that the rib 343 snaps onto the rib 322 to hold the drinking tube 340 securely in place. Also, the plug 325c is hermetically engaged in the hole 341a.

Continued insertion of drinking tube 340 means that shoulder 342a pushes against tab 330 causing said tab 330 to swing radially outwards as it pivots about bridge 332 . This means that the leg portion 331 of the tab 330 is joined under the flange 324 on the outside of the recess 324a.

It should be noted that a void 350 is formed between the flange 324 and the annular retaining rib 343 .

Referring now to FIG. 48 , the cover 325 is shown flipped to its open position so that the nipple 341 is exposed through the base 320 . The window 327 in the open end of the lid edge portion 325b is clearly shown.

It will be noted that tab 330 is now hidden from view, indicating that lid 325 has been opened. This is because when the lid 325 is opened, the leg portion 331 of the tab 330 abuts against the flange 324 so as to prevent the tab 330 from being lifted by the rest of the lid. Thus, when the lid 325 is lifted, the bridge 332 breaks, which releases the tab 330 . Tab 330 drops into void 350 as shown in FIGS. 49-53 . Tab 330 remains in void 350 during subsequent opening and closing operations.

It will be noted that the drinking tube nipple 341 will be clearly visible through the lid 325 because the tab 330 is no longer aligned with the window 360 . In this embodiment, drinking tube nipple 341 and cap 325 are formed of differently colored materials so that drinking tube 340 can be clearly seen through window 327 and as an indication that tab 330 is no longer present.

Referring now to FIG. 54 , there is shown an enlarged cross-section of a region with a tamper-evident tab 430 formed in accordance with other embodiments. Tab 430 is very similar to tab 330 shown in FIG. 46 . However, the tab 330 shown in Figure 46 is held from above by a single bridge, while the tab 430 is held by side bridges 432 at the side.

In FIG. 55 , a closure according to a further embodiment is indicated with reference numeral 510 . The closure includes a base 520 having a generally cylindrical rim portion 520a and a cover 525 having a top plate 525a. The cover 525 also includes a generally cylindrical side edge portion 525b. In this embodiment, the side edge portion 525b has a portion directly opposite the hinge, which is similar to a visor in a motorcycle helmet.

At the junction between the top of the base 520 and the outside of the cover 525, a tamper evident member 530 can be seen. Such a tamper-evident member 530 is in the form of a tab and is releasably connected to the cover 525 . 58 and 59, the tamper-resistant member 530 has a protrusion 533 on its lower radially outward side. The cover is molded in the open position. At least a portion of the tamper-evident member 530 passes through the opening in the top surface 524 of the base and at least partially into a void or pocket 531 provided in the base 520 when the lid is initially closed. The protrusion 533 is incorporated under the top surface 524 of the base 520 . The protrusion is formed such that it allows the tamper evident member to pass through the opening in the top surface 524, but will not allow it to be removed. Thus, when the lid 525 is first opened, the breakable bridges 532 break due to the protrusions 533 preventing the tamper-evident member 530 from leaving the gap 531 below the hole provided in the top surface 524 of the base 520, which breaks A piece 532 connects the tamper evident member 530 to the cover 525 . When this occurs, the tamper evident member moves further into the void or pocket 531 .

A cross-sectional side view of a portion of a closure 510 is shown in FIG. 59 where the closure has been initially opened and reclosed. Thus, the breakable bridge 532 has been broken and the tamper-evident member 530 remains in the void 531 provided in the upper portion of the top surface 524 of the base 520 . A gap 527 is left between the underside of the cover 525 and the upper surface 524 of the base, through which gap 527 the dispensing member 540 is visible.

Figure 56 shows a perspective view of the closure 510 after it has first been opened and then closed again. In the case where the tamper-evident member 530 is provided in advance, the gap 527 can be seen. No other components of the closure are located between the gap 527 and the drinking tube 540 within the closure 510 . Accordingly, the drinking tube 540 can be seen through the gap 527 . If the drinking tube is made of a different material and/or the color of the drinking tube is different from the color of the lid and/or base, and in particular from the color of the tamper-evident member 530, the drinking tube can be seen more clearly through the gap 527 And thus provides evidence in a more obvious manner that the closure has been opened and closed again.

Figure 57 shows the closure 510 in the open position. The tamper evident member 530 cannot be seen because it falls inside a void 531 provided in the upper surface 524 of the base 520 . Just above the tamper-resistant member 530 , a clamping portion 525 c is provided at an upper end portion of the cover 525 . It is understood that the cover 525 is connected to the base 520 by hinge means 526 . The cover and base may be molded as one piece or may be formed as separate parts. Closure 510 may fit to container 515 . The closure 510 may include a further tamper-evident member 523 disposed at the lower end of the base 520 . Such a tamper-evident member 523 provides evidence that the closure has been removed from the container 515 and operates in the well-known manner of tamper-evident tabs.

60 to 65 relate to other embodiments of closures generally indicated by the reference numeral 610 . FIG. 60 is a cross-sectional view of closure member 610 . It is appreciated that the closure 610 includes a base 620 and a cover 625 . The lid has a top surface 625a and an extension 625c on one side for gripping and opening the lid 625 . A drinking tube or dispensing member 640 is located within the closure 610 . This is a separate member that fits inside the base 620 and cover 625 . Base 620 and cover 625 pivot together by hinge means 626 . The cap 625 has an annular protrusion 625d depending from the top surface 625a and pressing against a portion of the drinking tube 640 to provide a seal. Moreover, the lid 625 includes an annular projection depending from the underside of the top surface 625a and which is in the form of a sealing hole to seal the inner surface of the drinking tube 640 so that when the lid is in the closed position prevent the contents of the container from leaking.

The drinking tube 640 includes an extension 641 that projects radially outward from the side of the drinking tube 640 at substantially the same axial height as the cover 625 when assembled with the base and/or cover The separation surface between the lower side of the base and the upper surface of the base 620. Also, the edge portion 625b of the cover 625 has a protruding piece 625e. Such projections protrude radially inwards at the lower end of the cover 625 in the region of the circumference diametrically opposite the articulation device 626 . A gap 627 is left between the lower end portion of the side edge portion 625 b and the upper surface of the base 620 in a region substantially opposite to the hinge device 626 . A void or pocket 631 is provided between drinking tube 640 and base 620 . The closure 610 is assembled with a tamper-evident member 630, which is a separate element having an upper ring 630a and a lower ring 630b connected by a breakable connection 632 at together (see Figure 63). When assembled, the tamper-evident member 630 fits between the base and lid and radially outwardly from the drinking tube 640 . The anti-tampering member 630 includes an upper protruding part 634 protruding radially outward and a lower protruding part 633 protruding radially inward. When the tamper-resistant member 630 is assembled with the closure 610 , the upper protrusion 634 is combined with the protrusion 625 e provided on the radially inner surface of the side edge portion 625 b of the cover 625 . Also, the lower protrusion 633 is combined with the protrusion 641 provided on the drinking pipe 640 . With this method. When the lid is first opened, it cannot be opened without the breakable connection 632 breaking. This is because the protrusions 634, 625e, 633, 641 prevent the lid from being opened. The protrusions 634, 633, 625e, 641 are all appropriately shaped to allow initial installation, they have an angled surface on one side so that corresponding protrusions can pass over each other during assembly. However, said projections also include an undercut on the side opposite to the side with the angled surface, said undercut engaging a corresponding undercut of the corresponding projection in order to prevent The protrusions pass over each other after installation.

The drinking tube 640 also includes a bore seal 644 which seals against the radially inner surface of an associated container (not shown). Furthermore, the closure 610 has a tamper evident member 623 at the lower end of the base 620 which operates in a similar manner to the well known tamper evident pendant members.

In Fig. 61, the hinge means 626 can be seen more clearly at the "rear" portion of the closure member diametrically or circumferentially opposite the gripping projection 625c. In FIG. 62 , a tamper-evident member 630 can be seen between the base 620 and the cover 625 . In Fig. 64, the tamper-evident member drops into the void 631 when the lid 625 has first been opened and reclosed. Thus, part of the drinking tube 640 can be seen through the gap 627 . In Fig. 65, drinking tube 640 is shown more clearly. The drinking tube includes the aforementioned annular extension 641 for engagement with the tamper-evident member 630 . Also included at an axially downward location is an annular projection 642 that seals against the interior of the base 620 .

Figures 66 to 67 relate to other embodiments of closures. This embodiment operates in a manner similar to that described above with respect to FIGS. 60-65 , whereby the closure has a separate tamper-evident member 730 . In this embodiment, the closure 710 is molded with the lid 725 in the closed position. The cover 725 may be connected to the base 720 via breakable bridges. The lid 725 of the closure 710 has a top surface 725a and a shield 725b in a manner similar to that described above. Also, the closure 710 has a tamper-evident strip 723 at the lower end of the base 720 in a similar manner to that described above. The gap 727 allows the drinking tube 740 to be visible even when the lid 725 is in the reclosed position when the tamper evident member 730 is dropped into the gap 731 (cf. FIGS. 69 and 70 ). Cover 725 may be connected to base 720 by hinge means 726 .

The tamper evident member 730 has an upper ring 730a and a lower ring 730b. The upper ring 730a includes protrusions 734 on a radially outer surface. The lower ring 730b includes protrusions 733 on the radially inner surface. The drinking tube 740 includes a protrusion 741 on its radially outer surface. The shield 725b includes a protrusion 725e on a radially inner surface at its lower end. When the tamper evident strip 730 is assembled with the closure, the protrusions 734 and 725e engage each other and the protrusions 741 and 733 engage each other. The protrusions are all formed with angled surfaces on one side to allow the protrusions to pass one over the other during assembly. The protrusion also includes undercut surfaces on the side opposite the angled surface, which abut each other when the lid is initially opened such that the breakable link 732 breaks and the lower ring 730b falls to the set position. In the void 731 in the base 720 .

Throughout the specification, as far as the usage of relative terms such as "upper" and "lower" are concerned, these terms relate to the orientation of the closure shown in the figures and are not to be construed as limiting the invention in any way. The term "axial" relates to the vertical axis through the dispensing aperture of the closure (as shown in the figures), while the term "radial" corresponds to said axis.

Although several different embodiments are described in this specification, many of the features in each closure are similar and/or identical. For example, each closure may be retained on the associated container by beading and/or threads. Furthermore, the shape and arrangement of the dispensing member in each closure is similar, said dispensing member having a "nipple" and means for coupling with the base. Therefore, not all of the different features in each embodiment have been fully described.

The main body 815 includes a generally cylindrical side wall 816 having at one end a tamper-evident annular ring 817 connected thereto by a plurality of breakable bridges 818 .

The side wall 816 is terminated at its end opposite the band 817 by an annular shoulder 816c extending radially inwards. A generally tower-shaped cover 830 is connected to the free end of shoulder 816c via hinge means 832 .

The interior of the side wall 816 includes internal thread formations 816a for engaging corresponding external thread formations on the container neck. The interior of the side wall 816 also includes an annular retaining rib 816b.

The interior of the strap 817 includes a plurality of upper flaps 817a for engaging under the locking ribs of the container neck so that if the closure is unscrewed, the strap will remain on the container neck.

Cover 830 includes a generally hexagonal top plate 834 from which a plug 836 depends. Opposite the hinge means 832, the lid 830 includes a small protrusion 838 for lifting the lid relative to the base 815 and flipping the lid open.

A tamper-evident strip 840 is disconnectably connected between the cover 830 and the base 815 . Strip 840 is terminated at either end by tabs 842 to allow it to be torn off when the lid is first opened.

Referring now also to FIG. 74 , drinking tube 820 includes a generally cylindrical lower portion 850 , a generally cylindrical central portion 851 , and a generally frusto-conical upper portion 852 .

The lower portion 850 includes an annular seal 854 having an outer sealing rib 856 . In use, the seal 854 enters the bore in the neck of the container so that the sealing bead 856 rests against its inner surface (as shown in Figures 75 and 76).

The central retaining portion 851 includes an annular base 858 from which extends a plurality of axially spaced ribs 860 for securing the insert 820 in the body 815 .

The base 858 also includes a plurality of radially outwardly extending retaining spokes 862 positioned at the bottom of each rib 860 . Between each spoke 862 is an angled shelf protrusion 864 that extends radially outward to substantially the same extent as rib 860 . Spokes 862 are generally L-shaped, with shorter legs extending away from upper portion 852 .

As best shown in FIG. 71 , upper portion 852 includes a curved, generally frusto-conical outer surface that defines a drinking tube. A cylindrical end portion 870 is located at the end of the side wall of the drinking tube opposite the central portion 851 . An annular aperture wall 872 extends inwardly from the free end of portion 870 and defines aperture 874 . An annular retaining rib 876 depends internally from the base of the tip portion.

Self-closing valve assembly 825 includes a body 826 and a valve 827 . Such a structure is known from the Applicant's International Patent Application No PCT/EP2005/053917. The valve body 825 includes a retaining rib 828 which clips onto the drinking tube retaining rib. Valve assembly 825 is received between retaining rib 876 and annular wall 872 as best seen in FIG. 71 .

Referring now to FIGS. 75 and 76 , drinking tube 820 is received into body 815 . Retention spokes 862 engage retention ribs 816b and ribs 860 fit snugly within the apertures defined by shoulders 816c to hold the drinking tube securely in place. The ribs 860 fit snugly within the cover 830 so as to hold it in the closed position. The plug 836 enters the hole 874 and abuts on the valve 827 to prevent it from opening when the lid is closed.

As will be fully understood from FIGS. 74 to 76 . Slots are formed between the spokes 862 and shelf-like protrusions 864 of the central portion 851 and the side walls 816 when the insert 820 is in place. Also, the ribs 860 establish a channel between the cover 830 and the base 858 .

As shown in FIG. 76 , when a fluid is sprayed on the closure 810 , the fluid will enter the interior of the closure through the hinge line interface between the lid 830 and the base 815 . If this occurs, fluid can pass between the ribs 860 and down the shelf-like projection 864 before passing through the slot and then between the closure and container threads and at the bottom of the side wall 816 outflow. This means that there is an unobstructed drain path for fluid to flow as it flows into the closure. The fluid must be forced through the discharge path, for example by blowing air at the closure.

Although illustrated embodiments of the present invention have been disclosed herein in detail with reference to the accompanying drawings, it should be understood that the invention is not limited to the precise embodiments shown and that, without departing from the invention, it is defined by the appended claims and Various changes and modifications can be made by those skilled in the art within the range defined by their equivalents.
