Description
2~9~381 INTEGRALLY MANUFACTURED CLOSURE FOR BOTTLES AND THE LIKF
FIELD OF THE INVENTION
The present invention relates to integrally manufactured closures of plastic makerial in particular for bottles and the like, comprising a closure cylinder having a pouring side and a closure lid that is integrally connected with the closure cylinder by means of at least one flexible connection which in its closing position closes the pouring spout and which can be folded from this closed position into an open position.
; BACKGROUN~ OF THE INVENTION
Known bottle-closures of this type have the cylinder and the lid connected with each other by one or several hinge or articulation elements in the process of their production.
This linking operates in the manner of a hinge and serves to prevent the loss of the lid when the closure is open. A spe~
cific exemplary version of such closures has on the opening side of the cylinder a tear-off stripe that is additionally integrally injection molded at the production and into which the lid snaps-i~ the first time the closure is closed after production, Such mechanical tamper evidencing means are poor-2 ~
ly or even not at all protected against unauthorized manipu-lations of the closure. With some skill it is poss-ible to open them for example by a slight warming-up of the closwre and to re-close the closure afterwards without such manipu-lation being recognizable.
Further known bottle-closures are of the screw-off type, whereby a lower collar is secured by punctuated molded connections. This collar is twisted or teared off the first time the closure is opened and then remains on the shoulder of the bottle.
Other known closures are two or multipart constructions, whereby a tear-oFf stripe is injection molded with one part o-F the closure. After assembling of the closure this stripe will hide a further part of the closure. Only removal of this tear-off stripe for example by tearing off liberates the lid and permits opening of the closure. The disadvantage of such tamper evidenciny closures is the risk of loosing the lid.
Still another type of known integral or multi-part bottle-closures consist of a capsule that is mounted on the bottle opening subsequent to the fllling of the bott'le and that is then deformed by shrinking under heat or by a mechanical action in such a manner that the closure cannot be opened without destroying the capsule. The disadvantage of such capsules is that they require an additional working step in the'bott'ling operation.
A purpose of the presen-t invention is to realize a closure for bottles or like articles giving an absolute guarantee of evidencing any tamper attempts and that can be manu-factured in one molding operation as integral closure to keep produc-tion costs low.
~9538~
Throughout the specification and claims the term bottle-closure is meant to also include closures for similar uses such as for example closures for small containers or similar items.
A further object of the invention is to realize a bottle-closure of high esthetical quality that can also be applied to cosmetic products and that may be manufactured with an unloosable lid that can be opened or closed with or without snap action.
SUMMARY OF THE INVENTION
In the inventive closure the flexible connecting element bet-ween the cylinder and the lid is not, as in the heretofore known closures, located and produced in one molding operation at the hinge-side o-f the closure but in that area of the closure where the same will be opened for use.
The flexible connection between the closure cylinder and the lid can be either a direct connection or one via an interme-d-iate integrally injection molded tear-off stripe. The first opening of the closure by flexing open the lid is only pos-sible after rupture or tearing-ofF of this connection which thus forms a tamper evidencing means. The realization o-f the connection as tamper evidence affords for a more economic mold production. An interlinked tear-off part allows an easy op~ical control of the tamper evidencing means.
A realization of the closure with a tear off stripe or a force-off or twist-off bar connected to the flexible con-nections makes possible a multitude of shapes, whereby a longer stripe will be particularly favorable -for handling.
The tear off stripe may additionaly be connected with the closure lid or the closure cylin~er at further locations, 2~3~1 preferably by punctuated interlinking produced in the in-jection molding step. This ensures a stable attachement of the tamper evidence on one of the parts of the closure with the result, that at assembling the closure parts are easier to interengage due to a determinated rotation axis.
A snap hinge may be arranged on or at that side of cylinder that is opposite the pouring side of the closure cylinder thereby affording for the closure lid to be flexed open about a hinge axis from its closed position into an open position.
Such arrangement has proved particularly convenient if spouts of larger diameter are required.
The closure lid part situated at the pouring side of the closure lid may be provided with a pouring tube and the counter surface of the closure cylinder may have an appro-priate counter part for receiving this pouring tube in the closed position of the lid. Such a construction may meet the request for an outstanding spout.

DETAILED DESCRIPTION
The embodiment according Fig. 1 to 3 shows a bottle-closure made of plastic material, preferably of polypropylene. In the injection molding tool the cavities of the closure cylinder 1 and lid 2 are arranged such that in manufacture the injected plastic material can flow from one cavity to the other.
Thereby a thin and flexible element 3 is formed between the closure cylinder 1 and lid 2 as a destroyab1e linking element which, in the represented example, is unitary but could also be of multiple form. Fig. 1 shows the bottle-closure as it leaves the mold after manufacture. After production the lid 2 is folded about the element 3 onto the cylinder l whereby fastening elements 4, shown here as fastening pins, engage in appropriate openings so that a permanent or at least durable securing of the lid 2 to the cylinder 1 in -this position is obtained. Simultaneously a pin 5 provided at the lid 2 enga-ges the pouring spout 7 in the cylinder 1 to tightly close .
2~9~
this opening. The resulting bottle-closure is shown in Fig.
2. In this form as shown in Fig. 2 the closure will then preferably be delivered to the market or to the filling lines.
The closure lid 2 comprises two lid parts 2a, 2b connected by a snap hinge. Lid part 2b, which is opposite the pouring side la, is permanently connected to the cylinder l by means of fastening elements 4, while lid part 2a on the pouring side can be snapped open about the hinge axis 8 from its snap-closed position on the closure cylinder l.
When the bottle-closure is opened the first time by a con-sumer the lid part 2a on which the tightening pin 5 is pro-vided, is flexed upwardly about the hinge axis 3, whereby the web 3 will be destroyed by tearing. In order to keep the lid part 2a in a determinated open position use is preferably made of a snap hinge system of the type described in European Patent ~ 056 469 which connects -the two lid parts 2a, 2b through the hinge axis 8 and the intermediate elements 9. The bottle-closure with the lid part 2a opened and held in this open position is illustrated in Fig. 3.
The second embodiment illuatrated in Fig. 4 to 7 the inven-tive bottle-closure has a tamper evidencing means shaped as tear off stripeO While in the first embodiment of Fig. ~ to 3 the tamper evidencing means is realized by the connecting element 3 in the manufacturing process, in this second emho-diment according to Fig. 4 to 7 a further cavity is provided in -the mold between the cavities of the cylinder l and the lid 2. This further cavity serves to form a tear ofF stripe 13 as tamper evidencing means. The method of manufacturing this second embodiment as well as the steps of the first closing of the closure correspond to those described above 8 ~
for the first embodiment. As long as the bottle-closure oF
Fig. 4 to 7 has not been opened a first time the tamper evi-dence stripe 13 lies closely around the closure as appears in Fig.7. After the stripe 13 has been torn ofF and the connect-ing element 3 ruptured for the first opening of the closure by a consumer, the bottle-closure of Fig. ~ to 7 has ~he same appearance as that shown in Fig. 2 and 3 for the first embodiment.
Fiy. 8 illustrates a possible variant construction of the closure of Fig. 4 to 7. In this variant the tear off stripe 13 of the previous embodiment is replaced by a stud 23 form-ing the tamper evidence means that has to be forced or twisted off for the first opening of the bottle-closure.
The third embodiment according Fig. 9 to 12 illustrates an alternative to the bottle-closure according to the second embodiment with a tear off tamper evidence. In this embodi-ment the tear o~f stripe 13 is connected to the periphery of lid 2 in segments by means of punctuated connections pre-fe-rably, as shown, in different levels formed at production.
Such additional connections of the tear of~` stripe could also be provided on the cylinder instead of on the lid as this is shown in Fig. 9a. The further steps correspond to those des-cribed with respect to the second embodiment. In order to facilitate a centering of lid 2 with respect to cylinder 1 when the closure is closed the first time after production, the lid 2 and the cylinder 1 are provided with centering means. In the illustrated example such centering means are shown as a pyramid-shaped device 42 on the lid 2 and an cor-responding recess 41 in the cylinder 1.
The fourth embodiment illustrated in Fig. 13 shows a bottle-closure similar to the previously described embodiments in .
2~38~
which the pouring spout 7 and the tightening pin 5 of the previous examples are replaced by a pouring tube 57 on the closure lid and a counterpart 55 in the closure cyltnder.
The ~ifth embodiment according Fig. 14 shows a bottle~closure with tear off stripe as tamper evidence means similar to the second embodiment. It differs however from the latter in that the hinge axis 68 of the openable lid is located at the wall of the cylinder and not at -the closure surface as in the em-bodiments of Fig. 1 to 13. Connecting elements 69 linked to a hinge part 70 serve to obtain a desired snap hinge effect.
Hinge part 70 may be secured to the closure cylinder 1 for example mechanically or by welding.
In the sixth embodiment illustrated in Fig. 15 and 16 the closure lid 2 is integrally connected with the closure cylinder 1 by a flexible connection~ preferably as shown by a snap hinge 68, 6g. Diagonally opposite to this first flexible connection a further element 72 is secured to the closure cylinder 1 via a flexible connection 13. If the two parts 2, 72, connected to the closure cylinder 1 at opposite locations each, are flexed onto the cylinder 1 in the correct order they permanently interengage via fastening means so that the closure can only be opened by destroying the second linking connection 13. The connection 13 may also be shaped as that shown in Fig. 8.

In the sixth embodiment illustrated in Fig. 15 and 16 the closure lid 2 is integrally connected with the closure cylinder 1 by a flexible connection~ preferably as shown by a snap hinge 68, 6g. Diagonally opposite to this first flexible connection a further element 72 is secured to the closure cylinder 1 via a flexible connection 13. If the two parts 2, 72, connected to the closure cylinder 1 at opposite locations each, are flexed onto the cylinder 1 in the correct order they permanently interengage via fastening means so that the closure can only be opened by destroying the second linking connection 13. The connection 13 may also be shaped as that shown in Fig. 8.
