Description

The present invention relates to a hinged lid closure made of art Containers for flowable goods according to the preamble of Claim 1. A hinged lid closure according to the preamble of the claim 1 is known from US 5,875,907 (AptarGroup, Inc.).

Hinged lid closures are used for containers or bottles that liquid or pasty media, such as personal care products (e.g. creams or Shampoos), detergents (e.g. dishwashing liquid), food (e.g. honey or ketchup) or drinks.

Such hinged lid closures are usually prefabricated and as separate units on the opening of a previously filled container assembled. The intended tamper-evident serves to indicate whether the closure is in the closed original condition or whether the Closure has already been opened, which is due to the destroyed target break of the tamper-evident device should be displayed.

A hinged lid closure is described in US Pat. No. 5,875,907 (AptarGroup), where a tamper-evident element via a predetermined breaking point is attached directly to the lower edge of the cover shell. For the first time The tamper-evident element must open radially after opening the cover pressed inside, causing the predetermined breaking point or breaking line gets destroyed. Only through the inward-looking authenticity Rungselement creates a space for reaching under the lid, so that this can be opened over a hinge. This device requires Opening the lid two steps, namely destroying the break and opening the lid, with the predetermined breaking point directly below the lower edge of the cover shell and thus only visually very is difficult to control. Especially with a fleeting check  or if the user's attention is distracted, it can lead that the predetermined breaking point is not noticed. This effect can be reinforced if the target in the known device breakage destroyed, but not through the quality assurance element the intended anchor held in its radially inner position becomes. The tamper-evident element could be in its origin move back, providing a visual control of the directly under the Lower edge of the cover jacket lying predetermined breaking point even more difficult becomes. Furthermore, the lid of the known device on the edge of the The predetermined breaking point is raised, causing skin irritation or injury of the user.

The invention has for its object a hinged lid closure specify that eliminates the disadvantages mentioned above, in particular one problem-free visual inspection of the predetermined breaking point from one if possible allows a wide angle of view and skin irritation or injury of the Prevents user from opening the lid. Furthermore, the hinged lid should maintain the quality of the container contents, if the lid of the dispensing closure is not completely closed.

This object is achieved by a hinged lid closure according to claim 1 solved, claims 2 to 33 relate to particularly advantageous Ausfüh Forms of the tax closure according to the invention.

According to the predetermined breaking point between the lid and the origi Quality assurance element at least partially at a distance below the Lower edge of the cover shell arranged. This causes the debit breakage on the surface of the cover is clearly visible and can be checked visually from a large angular range without any problems. In particular, the visual inspection of the predetermined breaking point is not there made difficult by the fact that the predetermined breaking point is located directly at the abutting edge between the lid and cap.

The tamper-evident element remains with the sealing cap at zer disturbed predetermined breaking point firmly connected, so that when it is opened again and closing the dispensing closure does not interfere, or from the lid as Ab case must be demolished.

The tamper-evident element is preferably immovable on the Sealing cap held; but it can also be done after destroying the target break on the cap around a fastening pin between two be positioned close to each other easily movable.  

In addition to the visual control, this is a haptic control of the Tamper-evident element possible: the predetermined breaking point is still the tamper-evident element is not destroyed by its additional fixed points immovable. In the event of a destroyed predetermined breaking point however, the tamper-evident element is movable in its plane and indicates that the lid has already been opened.

The distance between the lower edge of the lid and the predetermined breaking point is preferred caused by an approach that extends from the bottom edge of the lid jacket extends approximately parallel to the main axis downwards. At his The underside is the approach over the predetermined breaking point with an upper edge of the Tamper-evident element connected. This ensures that the visual inspection body from the critical and bad to check the butt edge between the cover and the sealing cap is laid down. It also ensures that the tamper-evident element on the Closure cap remains attached so that it is not the subsequent opening Opening and closing processes of the lid is disruptive.

In a particularly preferred embodiment, the cap jacket instructs its outside a receptacle for the approach to the lower edge of the lid and the tamper-evident element. This will extend beyond the scope of Avoiding protruding parts of the cap during transport or damaged or disrupted when handling the container ten.

The resting position of the tamper-evident element is preferred by secured a locking pin from the bottom of the recess in the Kappenman Tel protrudes radially to the main axis of the cap and which in a Appropriate locking opening engages in the tamper-evident device element is introduced. It is also possible that to produce a Snap fit the peripheral edge of the tamper-evident element as well its inclusion in the cap undercuts each other accordingly ten are, so that a rest fit of the tamper-evident element is achieved in this way.

These or other options for realizing a shape and / - or frictional engagement can be used both individually and in combination become. In a particularly preferred embodiment, the rest seat with a locking pin in the receptacle for the tamper-evident element and a corresponding latch opening in the tamper-evident element provided, the tamper-evident element after the Zer interfere with the predetermined breaking point by a certain angle of z. B. 15 ° between  can move two positions within the recording. The Originali The security element is still firmly connected to the cap to avoid the generation of waste, the mobility of the However, tamper-evident element shows not only visually, but also haptically indicates that the predetermined breaking point has been destroyed.

More are preferred on the hinged lid closure according to the invention Elements attached, which a comfortable handling of a hinged lid ver allow closure and an associated container. In particular is a diaphragm valve is provided which is introduced into the closure cap, to control the amount of liquid dispensed or a ver Visible liquid release and the quality of the container contents to prevent impairing air access.

A drinking spout facilitates drinking from one with the invention ß hinged lid closure provided container, especially for sporty Activity, and improves drinking hygiene.

According to a further embodiment of the invention, the approach of Ver end cap a uniform stock connected by predetermined breaking points part of the form of the tamper-evident element, such that according to Zer disruption of the predetermined breaking points of the tongue-like approach on the outer Surface of the tamper-evident element protrudes and the Use of the container with a hinged lid lock Pack indicates.

Fig. 1 is a perspective view showing a first embodiment of a hinged-lid closure according to the invention with a closure cap 100 and a cover 200.

The closure cap 100 has a substantially round head plate 110 , from the outer edge of which a cap jacket 120 extends downward. The cap jacket 120 is provided on the inside with means for fastening the closure cap 100 on a neck of the container, in particular a bottle.

In Fig. 1, 2 and 4, a drinking nozzle 130 of the head plate 110 extends centrally cone shape from the center upwards. The drinking spout 130 has a removal opening 140 through which a flowable material, in particular a beverage, can be removed when the cover 200 , as shown in FIG. 1, is in the open position.

The drinking spout 130 is arranged essentially rotationally symmetrically to a main axis extending through the removal opening 140 and has a maximum diameter at its foot end facing the head plate 110 . At its end facing away from the head plate 110 , the drinking neck 130 tapers in two places, as is shown in particular by the front view shown in FIG. 2.

According to FIG. 4, a membrane valve 190 for the controlled dispensing of liquid from a container is arranged on the drinking nozzle 130 or the cap jacket 120 . This diaphragm valve 190 automatically receives the quality of the flowable material in the container by its self-closing function, since it only opens when there is a pressure difference between the inside and the outside of the diaphragm valve 190 .

At the edge of the head plate 110 of the closure cap 100 , a circumferential latching edge 112 is provided ( FIG. 1), which interacts with a complementary latching edge 222 of the lid 200 when the lid 200 is in a position closing the dispensing opening 140 . In the locking edge 112 of the head plate 110 are two diametrically opposite Stabilisie approximately grooves 114 are introduced, which cooperate with complementary stabilizing webs 224 of the lid 200 to position the lid 200 in its closed position on the cap 100 exactly and rotatably. Since for closing bottles or containers with the hinged lid closure according to the invention, only the hinged lid 200 of the closure above the handle element may be gripped because of the protruding handle element 230 , it is ensured that a torque to be exerted on the hinged lid by a closing head of a closer part of a closing machine for screwing on the Closure on a bottle or container neck is reliably transferred from the hinged lid to the closure cap without damaging the hinged lid closure.

The cap jacket 120 is provided on two diametrically opposite sides with parallel to the main axis, that is perpendicular to the head plate 110 , the longitudinal grooves 122 ( Fig. 1), which allow a better detection of the United cap 100 .

According to FIG. 1, a receptacle 350 for an extension 330 is molded into the outside of the cap jacket 120 and is attached to the cover 200 . The receptacle 350 is introduced in the outside of the cap jacket 120 and is open both radially outwards up to the top plate 110 of the closure cap 100 and from the cap jacket 120 . The receptacle 350 is tapered in the direction of the lower end of the receptacle 350 and has its maximum width in the circumferential direction at the height of the head plate 110 .

The lower part of the receptacle 350 opens in the axis-parallel direction in a recess 340 in the outside of the cap jacket 120 for an originality assurance element 320 , which is attached to the extension 330 and thus to the cover 200 . The recess 340 for the tamper-evident element 320 consists of a substantially rectangular cutout, the radial depth of which essentially corresponds to the thickness of the plate-shaped tamper-evident element 320 . Both the circumferential edge of the tamper-evident tamper-evident element 320 and side walls 342 and the lower transverse wall 344 of the recess 340 are cut back accordingly, so that a snug fit of the tamper-evident element 320 in the recess 340 in the cap jacket 120 of the closure cap 100 is provided securely when the cover 200 is closed for the first time after production, the tamper-evident element 320 being pressed into the recess 340 . In deviation from the above-described Ausgestal the tamperproof processing may also be provided depending on the desired requirements for such a tamper-evident, the plate-like tamper-evident member 320 instead of the extension 330 with the lower edge of the cap skirt 220 and this in turn via the predetermined breaking point 380 with the lug 330 connect to. Accordingly, in this case, the receptacle 350 for the approach 330 and the recess 340 for the plate-like tamper-evident element 320 on the cap jacket 120 would be exchanged. In addition, it is of course possible to inject the tamper-evident element 320 and the extension 330 in different colors in order to reinforce the labeling of the tamper-evident element and to increase the level of attention. Furthermore, instead of weakening the material that is used for the tamper-evident element 320 and the attachment 330 , the predetermined breaking point 380 can also be produced from a soft plastic, which may have a different color, which makes the predetermined breaking point visible as a colored dividing line.

Approximately in the middle of the recess 340 for the tamper-evident element 320 , a locking pin 360 is provided, the height of which corresponds approximately to the depth of the receptacle 350 , so that the locking pin 360 does not protrude beyond an imaginary envelope cylinder of the cap jacket 120 .

The detent pin 360 cooperates with a centrally arranged in the tamper-evident member 320 snap-in opening 370, so that the Originali tätssicherungselement 320 can be kept on the latch pin 360 in the recess 340 snap fit.

It is understandable that the locking pin 360 and the locking opening 370 with the above-mentioned undercuts of the walls 342 , 344 and the originality assurance element 320 can be used together, but in each case also alone. Of course, it is also possible to choose 320 as or to design the materials of the recess 340 and the tamper-evident element whose surfaces so that a backup of the origina surance elements 320 is ensured in the recess 340 by friction or interference fit.

A lower edge 150 of the cap shell 120 is connected via predetermined breaking points 160 to a retaining ring 170 which engages under a bead of the container terhalses. This ensures that when the entire dispensing closure is unscrewed or detached from the associated container, the locking ring 170 is destroyed, so that it can be checked visually whether the hinged lid closure has been released from the container.

The cover 200 is a snap-film hinge, the mung approximately at the level of the top plate 110 to the cap skirt 120 of the Ausneh 340 is disposed diametrically opposite to the tamper-evident member 320 via a hinge 400 here permanently connected to the closure cap 100th On its lower edge 226, the cover 200 has a locking edge 222 on the inside and two diametrically opposite stabilizing webs 224 for a locking connection with the locking edge 112 or the stabilizing grooves 114 of the closure cap 100 .

The hinge 400 diametrically opposite extends from the lower edge of the lid 200 of the approach 330 , on which the tamper-evident element 320 is arranged with the locking opening 370 already explained.

Above the extension 330 , a grip element 230 is provided as a handle for operating the hinged cover 200 , which projects as a radial projection of the lower edge of the cover. The grip element 230 can be clearly seen in particular in FIGS. 3 and 4.

Fig. 2 shows a front view of both the Ver shown in FIG. 1 closure cap 100 and the lid 200 shown in Fig. 1, wherein both elements separately for reasons of clarity and simplicity and above each other.

In FIG. 2, the attachment of the rectangular shaped originality Siche seen approximately elements 320 via a predetermined breaking point 380 on the hub 330, which is formed starting tapered from the lower edge of the lid 226, in the direction of the tamper-evident member 320 toward. The predetermined breaking point 380 is a notch of reduced material thickness, which extends over the entire connection area between originality element 320 and attachment 330 . Of course, other forms of a predetermined breaking point can also be provided here, e.g. B. webs, perforations or the use of other materials in the area of the predetermined breaking point 380 , which have a reduced tear strength compared to the material of the quality assurance element 320 or the approach 330 .

The recess 340 for the tamper-evident element 320 and the on 350 for the approach 330 are substantially congruent in shape, but the side walls 342 and the lower transverse wall 344 are designed so that they allow a snug fit of the tamper-evident element 320 by means of undercuts (see in particular Fig. 6). Mainly, however, the locking pin 360 already explained with reference to FIG. 1 serves for secure locking into the locking opening 370 of the originality assurance element 320 in the recess 340 .

In the embodiment shown in FIGS. 2 and 5, the projection 330 extends from the lower lid edge 226 downward by 1.7 mm. The tamper-evident element 320 has an area of approximately 6 × 9 mm. The handle element 230 extends in the central region of the approach about 2 mm beyond the outer circumference of the lid 200 so that the lid 200 can be pivoted about the hinge 400 by means of the Griffele element 230 .

The lid 200 , similar to the cap 100 , in the front loading area of the cover jacket 220 , the hinge 400 diametrically opposite an area with longitudinal grooves 223 . These longitudinal grooves 223 also enable better gripping of the cover 200 , so that the cover can also be opened by gripping the cover shell 220 without using the grip element 230 . In particular, the longitudinal grooves 223 enable a perfect frictional connection between the closing head and the hinged lid during assembly, in particular when the hinged lid closure is screwed onto a container or bottle. Of course, the increased friction circuit instead of the longitudinal grooves by other types of roughening the surface of the hinged lid, such as. B. by knurling, etc., who achieved the.

FIG. 2 also shows the securing ring 170 fastened to the cap jacket 120 of the closure cap 100 by means of the predetermined breaking points 160 .

Fig. 3 shows a plan view of the hinged lid closure shown and opened in Fig. 1, the closure cap 100 being shown on the left and the lid 200 being shown on the right. Both elements are connected to one another via the hinge 400 already explained. In this illustration, the removal opening 140 , which is formed and surrounded by the drinking nozzle 130 , and the stabilizing grooves 114 in the latching edge 112 of the closure cap 100 , which interact with the stabilizing webs 224 in the latching edge 222 of the cover 200 , and the ones arranged on the cap jacket 120 Areas with the longitudinal grooves 122 can be seen. In the lid 200 of the sealing ring 240 is arranged, which closes the extraction opening 140 in the closed state of the lid 200th

The tamper-evident element 320 is slightly curved in the circumferential direction in order to adapt to the outer contour of the closure cap 100 .

The hinge 400 diametrically opposite the recess 340 for the tamper-evident element 320 and the receptacle 350 for the attachment 330 and the centered locking pin 360 are arranged in the cap jacket 120 of the closure cap 100 . In this embodiment, the cap jacket 120 of the closure cap 100 is formed somewhat thicker in the region of the recess 340 or the receptacle 350 than in the remaining region of the closure cap 100 . Of course, the closure cap 100 can also be designed with a constant thickness of the cap shell 120 , in particular also in the region of the recess 340 and the receptacle 350 .

Fig. 4 shows a cross section through the Ausfüh approximate shape shown in Fig. 3 along the line IV-IV. In addition to the features already explained, which are provided with identical reference numerals in FIG. 4 but are not described again in detail, in FIG. 4, in particular the sealing ring 240 explained in connection with FIG. 3, it can be seen in the cover 200 . The sealing ring 240 consists of a substantially cylindrical wall extending from the top plate 210 into the interior of the cover 200 . An annular sealing edge 242 of the sealing ring 240 is chamfered radially inwards, so that when closing the Dec kels 200 it seals against the overlying, complementarily chamfered, ring-shaped sealing lip 132 of the drinking nozzle 130 of the cap 100 .

As soon as the cover 200 is fully engaged in its closed position, the cylindrical sealing ring 240 rests on the area 134 of the drinking neck 130 , which is also cylindrical, so that a sealing of the removal opening 140 is achieved. The seal is further strengthened by the fact that the cylindrical portion 134 is expanded of the drinking spout 130 downward away from the extraction opening 140, radial, so that the sealing ring is pressed 240 with a higher pressure against the side walls of the drinking spout 130 and seals.

The cap 100 has on the inside of the cap shell 120 with tel 180 for fastening the cap 100 on the neck of a container, in particular a bottle. These fasteners 180 are designed here as an internal thread that can be screwed onto the external thread of a bottle. Of course, deviating fastening means for the closure cap 100 on a container are also conceivable, e.g. B. snap connections or a friction or snug fit. The fastening of the closure cap 100 is of course dependent on the container with which the hinged lid closure according to the invention is to be used.

A membrane valve 190 is arranged in the closure cap 100 in the lower region of the drinking nozzle 130 . The diaphragm valve 190 is made of flexible material, such as. B. silicone or PE and is sealingly connected to the drinking neck 130 at its edge region. A clamping ring 192 closes within the cap 100 or the drinking spout 130 an annular flange 193 of the diaphragm valve 190 , which is connected via a cylindrical connecting sleeve 198 with a membrane 194 Ver. The wall thickness of the connecting sleeve 198 is substantially less than the thickness of the membrane 194 , which is concave in the direction of the removal opening 140 .

As FIG. 4 shows, the membrane has a cross-shaped slot 194 to 196, can flow through the fluid when the fluid at a positive pressure be voted to the membrane 194 is applied. Before this opening pressure of the diaphragm valve 190 is reached, the elastic, flexible connecting sleeve 198 of the diaphragm valve 190 is compressed or inverted, without the cross-shaped slot 196 of the diaphragm valve 190 being opened. As a result, the diaphragm valve 190 prevents the fluid from escaping from the container even when the lid 200 has not been closed completely. The diaphragm valve 190 is particularly suitable for squeeze bottles made of plastic with a hand-compressible, ela-elastic wall, so that the excess pressure required to open the diaphragm valve 190 can be caused in the squeeze bottle. The Mem branventil 190 can by appropriate selection and dimensioning of the material for its manufacture to very different operating conditions, such as. B. the viscosity of the fluid to be dispensed, adjusted.

The details V and VI are described below with reference to FIGS. 5 and 6 be. FIG. 5 shows the tamper-evident element 320 , which is attached to the shoulder 330 by means of the predetermined breaking point 380 . The originality assurance element 320 and the extension 330 have on their outside in Fig. 5 on the left a substantially flat surface, which in connection with that on the back and inside (in Fig. 5 on the right) in the border area between the extension 330 and the Tamper-evident element 320 incorporated stage leads to the predetermined breaking point 380 , which has a very small material thickness. This ensures that in the event of a tensile load acting on the tamper-evident element 320 and the approach 330 , when the tamper-evident element is fastened to the sealing cap 100 and the cover 200 is opened, the predetermined breaking point 380 is destroyed. The approach 330 remains connected to the lid 200 , while the tamper- evident element 320 remains held on the cap 100 .

Due to the arrangement of the predetermined breaking point 180 at a distance below the lower edge of the cover shell 220 or the handle element 230 , the broken predetermined breaking point can be checked visually from many viewing positions, in particular the destroyed predetermined breaking point is not covered by the handle element 230 .

The tamper-evident element 320 is further fastened to the closure cap 100 , in particular due to the locking pin 360 ( FIG. 6) which engages in the locking opening 370 . In FIG. 5 it can also be seen that the lower end 324 of the originality securing element 320, which is remote from the grip element 230 , is designed such that it can be latched to the lower transverse wall 344 of the recess 340 for the tamper-evident element 320 by means of undercuts ( FIG. 6 ).

FIG. 6 shows the detail identified by VI in FIG. 4, which in particular illustrates the structure of the recess 340 for the tamper-evident element 320 and in the upper region the receptacle 350 for the attachment 330 . Here, in particular, the walls of the cap jacket 120 in the region of the recess 340 for the tamper-evident element 320 can be seen , into which the locking pin 360 projects with a diameter of 1.5 mm. Overall, the area of the cap shell 120 , in which the recess 340 and the receptacle 350 for the tamper-evident element 320 and the extension 330 are arranged, is thicker compared to the other wall thickness of the cap shell 120 for reasons of stability. The normal wall thickness of the cap jacket is approximately 1.1 mm, while in the area of the recess 340 or the receptacle 350 it is 2 mm.

The lower transverse wall 344 of the recess 340 for the tamper-evident element 320 is formed such that the lower end 324 of the originality ticherungselements 320 is held in the recess 340 by means of an undercut. It should be noted that the lower transverse wall 244 , the side walls 342 and the lower end 324 of the tamper-evident element 320 can also be straight, as shown in FIG. 7. The attachment of the tamper-evident element 320 is in this case by the locking pin 360 and the locking opening 370 and if necessary. secured by a fit of the tamper-evident element 320 in the recess 340 .

In the enlarged detail shown in FIG. 6, the locking edge 112 of the closure cap 100 already explained above is also shown, which cooperates with the complementary locking edge 222 of the cover 200 in a closed position thereof.

In Fig. 7, a second embodiment of the hinged-lid closure of the invention in Fig. 6 shown enlarged detail is shown. All previously described characteristics are substantially the same, only the lower transverse wall 344 of the recess 340 for the Originali tätssicherungselement is just so formed to extend radially substantially so that no undercut is operative upon insertion of the tamper-evident member 320 into the corresponding recess 340th The tamper-evident element 320 is therefore only held in the recess 340 by the locking pin 360 and the associated locking opening 370 .

Furthermore, in the second embodiment shown in FIG. 7, the receptacle 350 for the attachment 330 is enlarged radially inward from the top edge of the closure cap 100 downward, so that the attachment for destroying the predetermined breaking point is 380 before the lid 200 is opened for the first time can be pressed radially inwards. However, it should be noted that the predetermined breaking point 380 can also be destroyed in this embodiment only by lifting the cover 200 by means of the handle element 230 , as has been explained in connection with the first embodiment.

Fig. 8 to 10 schematically show a third embodiment of to the invention OF INVENTION hinged lid closure. Similar or identical components are provided with identical reference numerals for the sake of clarity.

In this embodiment, the approach 330 is integrated into the form of the originality assurance element 320 . The approach 330 forms a central, tongue-shaped section of the plate-shaped originality assurance element 320 . The outline of the tongue-shaped cutout for the approach 330 in the tamper-evident element 320 is, with the exception of the flexible and uniformly formed tongue root on the lower edge of the lid edge with the material of the same through predetermined breaking points 380 , such that when a force is exerted on the lid edge in the opening direction Approach 330 hanging on the edge of the lid can be broken out and lifted from the plate-like tamper-evident element 320 and, in a subsequent closed position, assumes a position protruding beyond the circumference of the closure cap 100 , indicating the use, due to a production-related memory effect. The built in the shape of the tamper-evident member 320 outline of the projection 330 is connected cherungselementes 320 with the surrounding material of the plate-shaped Originalitätssi by predetermined breaking points 380 for sale. The originality assurance element 320 and the approach 330 can advantageously consist of materials of different colors. The predetermined breaking point 380 between the tamper-evident element 320 and the extension 330 can also consist of a soft plastic. The soft plastic can have a color that differs from the color of the tamper-evident element 320 and / or the extension 330 .

In particular, Fig. 8 shows a view of the hinged-lid closure in a closed state before the first opening. The lid 200 sits on the cap 100 and the tamper-evident element 320 , which is integral with the lid 200 z. B. has been produced in an injection molding process, for the first locking of the hinged lid closure on the cap 100 and in the common recess 355 for the approach 330 and the tamper-evident element 320 ( FIG. 10), where it was pressed due to the engagement of the locking pin 360 is held in the locking opening 370 of the tamper-evident element 320 .

In contrast to the first and second embodiment, the extension 330 is not arranged exclusively above the tamper-evident element 320 , but projects from the lower edge 226 of the cover jacket 220 into an interior of the tamper-evident element 320 . In this embodiment, the predetermined breaking point 380 is designed as a perforation line which is automatically destroyed by lifting the cover 200 , in particular by actuating the grip element 230 .

The predetermined breaking point 380 consisting of thin material webs is essentially U-shaped and tapers in the direction of the U-web from the lower edge 226 of the cover shell 220 , to which the open side of the U-shaped predetermined breaking point 380 adjoins, to a distance that is a maximum of 3 mm below the lower edge. Instead of the tongue shape shown of the predetermined breaking point 380 and, as a result, also of the approach 330 , the shape of the approach 330 integrated into the plate-like tamper-evident element can be arbitrary, for. B. taper downwards. The only prerequisite is that the projection 330 tapers downward so that it can break out and lift out of the tamper-evident element 320 , destroying the predetermined breaking point 380 , when the cover 200 is subjected to sufficient lifting force.

As explained in connection with the first two embodiments, the tamper-evident element 320 is held on the closure cap 100 even after the predetermined breaking point 380 has been destroyed by positive and frictional engagement.

Fig. 9 shows the hinged lid closure immediately after manufacture in an injection molding machine. The tamper- evident element 320 is shaped so that it extends substantially parallel to the lower edge 226 of the lid 200 and via an articulated connection 228 , which is realized in this embodiment by reducing the material thickness in this area, on the handle element 230 of the lid 200 is movably attached.

For the initial closing of the hinged-lid closure, the origina is surance element 320 about the articulation 228 rotates by about 90 ° ge until a stop 326 of the tamper-evident member 320 to the handle element 230 and the lower edge 226 abuts the cap skirt 200th This position of the tamper-evident element 320 , which corresponds to the position of the tamper-evident element 320 shown in FIG. 8 in a locked state of the hinged lid closure, is shown in dashed lines in FIG. 9.

In the partial cross section of the third embodiment of the hinged lid closure according to the invention in FIG. 10, the lid 200 on the closure cap 100 is closed, but after the lid 200 has been opened for the first time, that is to say after the predetermined breaking point 380 has been destroyed ( FIG. 8). Due to a memory effect, which is caused by the position explained in connection with FIG. 9, the approach 330 tends to stand out from the cap jacket 120 of the cap 100 , so that it from the common recess 355 for the tamper-evident element 320 and the approach 330 protrudes. The projection 330 protruding from the common recess 355 and from the outer surface of the cap shell 120 clearly shows that the predetermined breaking point 380 has been destroyed and the hinged cover has already been opened. The advantages explained in connection with the first two embodiments, in particular the clear visibility of the destroyed predetermined breaking point 380 at a distance below the lower edge 226 of the cover shell 220 and the possibility of opening the cover 200 via the grip element 230 without the pressure of an operator's fingertip must exert on the broken edges of the destroyed predetermined breaking point 380 are also ensured in this embodiment.

It is understandable that FIGS . 8 to 10 only schematically illustrate the essential differences of the third embodiment from the first two embodiments, many of the features explained in connection with the first two embodiments not being shown. Of course, all features of the embodiments can also be combined with one another without departing from the subject matter of the present invention.

Those disclosed in the claims, the description and the drawing Features of the invention can therefore be used both individually and in combination be essential for the implementation of the invention.
