Container with a security closure
The container comprises a container body (1) and a sealing cap (9) which may be screwed to the container body (1). Barbs (5) are circularly distributed on the container body (1). Said barbs (5) each comprise a run-up ramp (7) and a locking surface (8). The sealing cap (9) is connected to a security ring (16) by means of break-off webs (15). The security ring (16) comprises projections (17) extending inwards from the inner circumference thereof, with run-up ramps (18) and locking surfaces (19). On closing the sealing cap (9) the run-up ramps (7;18) slide over each other. On unscrewing the sealing cap (9) an opposing blocking occurs due to the locking surfaces (8;19). The security ring (16) is thus blocked relative to the sealing cap (9), whereupon the break-off webs (15) are torn off.
This application claims the priority of PCT patent application No. PCT/IB2001/002017, filed 29 Oct. 2001, the disclosure of which is incorporated herein by reference in its entirety.
BACKGROUND OF THE INVENTION1. Field of the Invention
The present invention relates to a container with a security closure, with a sealing cap which may be screwed onto the container body, and with a security ring connected to the sealing cap through break-off webs.
2. Prior Art
Security closures are used to inform a purchaser and user, resp. of a container equipped with a security closure whether the container has already been opened earlier and possibly if a portion of its contents has already been extracted. A great many designs of security closures have become known, whereby often a given security closure can be used for only one container design and not universally, which means that different containers such as e.g. bottles, plastic containers for medical liquids and tube shaped containers necessitate a respective particular design of a security closure.
SUMMARY OF THE INVENTIONHence, it is a object of the invention to provide a container equipped with a security closure which a security closure which can be produced in a great variety of different structural designs.
It is a further object of the invention to provide a container of the kind mentioned above in which the container body comprises resiliently yielding barbs which are arranged at mutual distances, each having a run-up ramp and a blocking surface, and in which the security ring comprises projections extending inwards and are adapted to cooperate in a resiliently yielding manner with the barbs.
Still a further object of the invention is to provide a container with a security closure which comprises a tube shaped container body with a dispensing cannula and which can be stored standing on its closure cap.
The container according to the invention is characterized by the features of the independent claim 1. Advantageous embodiments can be derived from the dependent claims.
BRIEF DESCRIPTION OF THE DRAWINGSThe invention can be better understood and objects different from those set forth above will become apparent when consideration is given to the following description. This description makes reference to the annexed drawings, in which:
Barbs 5 which are arranged in a wheel like fashion are located on the shoulder portion. These barbs are arranged along the outer circumference of a wheel-like shaped disc 6 formed integrally with the shoulder portion 3 and accordingly reinforcing same. Every barb 5 includes a run-up ramp 7 and a blocking surface 8.
The above described parts are the same for all embodiments of the invention.
The sealing cap 9 includes a outer jacket part 10. The sealing cap 9 includes, furthermore, a stub part 11 extending coaxially to the outer jacket part 10 which is equipped with a inner thread 12 which, in order to close the container, is to be screwed onto the outer thread 4 of the cannula. The outer jacket part 10 is integrally connected to the stub part 11 through a end plate 13. The diameter of the sealing cap 9 is at least approximately the same as the diameter of the container body 1 such as can be seen for instance in
The outer jacket part 10 is connected through break off webs 15 to a security ring 16.
This security ring 16 includes in turn projections 17 which are directed inwards. These projections 17 include in turn run-up ramps 18 and blocking surfaces 19. The projections 17 are also designed in form of barbs.
The barbs 5 of the container body 1 are designed in form of a gear rim which is firmly attached to the container body 1 or its shoulder portion 3, resp. and have teeth facing outwards whereby these barbs define with the respective radius lines of the circular shape of the security ring a angle.
The projections of the security ring 16 define also with the circular shape of the security ring a angle.
The projections 17 of the security ring 16 are arranged inversely relative to the barbs 5 of the container body 1 so that when the sealing cap 9 is screwed onto the container body 1 the run-up ramps 18 of the security ring 16, since they are made of a plastic material, slide over the barbs 5 which are also made of a plastic material in a elastically yielding manner. However, when the sealing cap 9 is unscrewed at container body 1 the blocking surfaces 19 of the projections 16 of the security ring 16 abut the blocking surfaces 18 of the barbs 5 of the container body 1 or its shoulder portion 3, resp. and block accordingly the security ring 16 which is connected through the break-off webs 15 to the sealing cap 9 so that upon a continued screwing off of the sealing cap 9 the break-off webs are ruptured and accordingly release the sealing cap 9.
A comparison between
In order to avoid a damaging or wear of the barbs 5, specifically their run-up ramps 7 and also of the projections 17, specifically their run-up ramps 18 when screwing the sealing cap 9 down, the sealing cap 9 includes at its outer jacket part 10 two driving dog projections 20 located diametrically opposite each other, such as specifically illustrated in
As can be seen in
The arrangement and the shapes of the barbs 5 on the shoulder portion 3 of the container body 1 are the same in all embodiments.
In contrast to the first embodiment this embodiment has the advantage that the screwing of the sealing cap 9 onto the container body proceeds by a smaller expenditure of force because the projections 24 present in the form of leaf springs can be pushed away by the barbs 5 at their run-up ramps 7 with a smaller expenditure of force. Thus, during a screwing off motion of the sealing cap the run-up ramps 7 of the barbs 5 are exposed to a much smaller wear. At this embodiment the projections 24 are also arranged in two groups arranged at a distance from each other, whereby the recesses 21 are located between these groups.
In this embodiment, see
In the embodiments described until now the security ring 16 is a unseparated ring which is connected to the sealing cap 9 exclusively though break-off webs 15.
According to a further variant the security ring 16 is a split ring. This embodiment is illustrated in
In this embodiment, attention is drawn to
This embodiment of the security ring is characterized in that at the one hand it is indeed connected through the break-off webs 15 to the outer jacket part 10 of the sealing cap 9 (see
When the sealing cap 9 is turned back for a breaking of the break-off webs the security ring 16 is obviously widened. It remains, however, connected at the portion 29 to the sealing cap 9. This portion 29 can also be torn off the sealing cap 9 in the sense of a break-off part. To this end, see hereto
While there are shown and described presently preferred embodiments of the invention, it is to be distinctly understood that the invention is not limited thereto but may be otherwise variously embodied and practised within the scope of the following claims.
