Description

"Cap"

The invention relates to a closure cap for containers of liquids or pasty materials with tamper-evident security.

In particular, the invention relates to such closure caps for Medicine bottles and / or tubes. With such containers it is important to determine to be able to determine whether the lock is still in use when the user is using it Original condition or not.

Containers of the type in question are, for example, in the sterilized Condition in pouches or bags or in tapes welded to pharmacies or theirs Suppliers delivered. The contents can then be removed with a hypodermic needle that occur when a tamper-evident part is removed from the container is introduced or an inserted seal or a metering device or Pierce pouring device in the container.

Sealing caps with tamper-evident security are available in numerous embodiments known. In general, a securing part is provided when the first time Opening the shutter is disconnected. To enable separation are Slits between the original in alit äts safety steep and the rest of the cap required. With the known closure caps of this type there is a risk that the contents of the container can be removed by sticking a hypodermic needle into the slot can without the tamper-evident security being separated or destroyed.

The invention is therefore based on the object of a closure cap to create that can be produced in a simple manner and in a simple manner by a associated container can be fastened, the authenticity of the container located in the container Filling goods recognizably guaranteed and easy to use, especially when used for the first time is.

According to the invention, this object is essentially achieved by that an upper cap part with a part of an associated container encompassing Edge part with the formation of a slot over tearable webs and at least one hinge-like connecting web is connected so that it can be opened and folded away.

The invention can be implemented in various ways.

According to a first embodiment is advantageous the upper cap part by a preferably flat, disc-shaped part of the cap lid educated. The cap is cylindrical or cup-shaped, with the Tamper-evident part consists of a part of the cap itself.

The diameter of the upper cap part is expedient smaller than the outer diameter of the cap.

To facilitate the initial opening, it is advantageous if the top cap portion has a portion of reduced thickness.

Appropriately, the section of lesser thickness is the (or the) hinge-like connecting webs approximately diametrically opposite. This will also the folding process, e.g. when closing again, is facilitated.

A still further improvement is obtained if, according to another Design of the embodiment of the cap lid at least one section having less thickness.

The section of lesser thickness of the cap lid is expediently arranged radially adjacent to the portion of lesser thickness of the upper cap part.

According to another embodiment of the invention, the cap is designed as an annular cap, with an annular rim, the annular rim with two diametrically opposite flap is provided and the upper tear-open and fold-away cap part as a cover cap, for example for a drip or dosing insert of the container, is trained.

To facilitate the handling or dosing of the product has advantageously the ring edge in the region of the tabs approximately axially parallel slots on.

According to yet another embodiment of the invention, the Cap designed as a cone and the upper part of the cap forms the tip of the cone.

In this embodiment, too, it is advantageous if the lower Conical part has areas of lesser wall thickness. Lying in an advantageous manner the areas of lesser wall thickness are approximately diametrically opposite.

In particular when using a closure cap according to the invention in containers with sugary or other crystallizing liquids the deformable sections are useful because by compressing the Cap any crystallization of the container contents at the points of lesser thickness can be eliminated. This also increases the accuracy of the dosage of each Contents ensured with the help of suitable dosing or pouring devices.

To attach the closure cap to the associated container, a cylindrical shell part of the cap has an internal thread for screwing on the cap have on a container with an external thread.

The cap according to the invention can, however, also be snapped on. clampable be trained. For this purpose, a cylindrical casing part of the cap is elastically stretchable educated. The elastic extensibility can be achieved by selecting the appropriate material for the cap or by means of a corresponding geometric design (e.g. corrugation, Ribs or the like) be ensured.

For use on containers with a thickened circumference, e.g. ring bead or transfer ring, it is useful if a cylindrical shell part of the cap this circumferential thickening overlapping edge portion has, which over the Circumferential thickening can be flanged or rolled.

In all the exemplary embodiments, it is advantageous if they can be torn off Bars are arranged approximately diametrically to the connecting bar (s).

An advantageous embodiment results when in the cap lid at least one sealing element is arranged. Here, according to a first embodiment, the sealing element can be designed as a single or multiple annular bead. At a Modification is the sealing element as in the interior of the container or one in it arranged dosing or pouring insert projecting pin formed.

It is advantageous in terms of production if the sealing element is integrally formed with the cap. The sealing element (s) are expediently provided on the tear-open and fold-down upper part of the cap.

According to a further embodiment of the invention is at the bottom of the edge portion 22, an inner ring 29 is provided as a tamper-evident.

According to one embodiment of the invention, there is the inner ring from individual knobs. Appropriately, these knobs are triangular in cross section educated.

To achieve tamper-evident security, i.e. for compulsory separation of the lower extended edge portion of the shell part of the cap is a ring-like one Separating cut provided in which web-like connections between the edge portion and the jacket section remain.

There are known capping machines with a greatly increased number of revolutions, whereby high circumferential speeds when screwing a cap onto a container can be achieved, or steeply increasing torques occur. When using such Sealing machines there is a risk that the tear-off webs of the tamper-evident section can be torn off as soon as it is screwed onto the container, without any deliberate action The shutter has opened.

In order to counter these difficulties, according to further development proposed the invention, the separating cut not as a circular line but in shape of successive spikes. This ensures that the individual Spikes one below the other when the cap is screwed onto a container as a driver act so that the high forces that occur are absorbed by the prongs of the separating cuts and are not transferred to the tear-off bars.

The formation of the prongs of the severing cut can be different geometric shapes. It is particularly advantageous if the prongs are sawtooth-like are formed with a steep edge in relation to the screwing direction of rotation of the upper part of the cap, which is followed by a flat edge. This will achieves that the steep edge of the upper part takes the steep edge of the lower part with it, while when unscrewing (opening the container) the flat edges slide against each other and make it easier to tear off the tear-off webs.

According to a modified embodiment, the prongs of the The separating cut is designed as a semi-trapezoidal prong, with a leading axially parallel Edge and a sloping rear flank.

According to a further modification of the training according to the invention can the prongs are also square, preferably rectangular or square be.

Another possibility is to make the separating cut wavy form, wherein the waves can be sinusoidal or semi-sinusoidal.

It if the cap from a corresponding one is particularly advantageous Plastic is made.

In all of the various exemplary embodiments of the invention, it is advantageous if the cap is made of plastic.
