The retention piece (22) latches the stopper (10) so that the stopper is fixed in a predetermined position in an axial direction. An independent claim is given for a container with lock/seal.

Description

The invention relates to a closure for a container, comprising a cap, wherein the cap forms an interior, in which a plug for sealing the container can be inserted in the axial direction, and wherein the cap holding pieces for holding the plug, which in the Inner space protrude, wherein the holding pieces lock the plug such that it is fixed in a predetermined position in the axial direction.

A closure for a container is already out of the WO 2007/063218 A1 known. Closures of the type mentioned are used to seal containers made of glass or plastic, which contain substances that z. B. are freeze-dried or sterilized. The containers are in particular small bottles or ampoules made of glass or plastic, from which sterilized or freeze-dried substances are removed with a hypodermic needle.

The containers are sealed against the atmosphere by a rubber stopper, with the stopper permanently held in the container by a cap. From the prior art is in particular known to introduce a rubber stopper in a glass ampoule and to firmly connect the stopper with the ampoule by a metallic cap.

In the manufacture of such a container, the material to be picked up is placed in the container and the closure with the stopper is first placed on the container such that a passage connects the container interior to the atmosphere. In this drying position, it is possible to dry the fabric inside the container. For this purpose, the plug is first inserted in the axial direction in the cap and held by holding pieces in this. The thus prefabricated closure can now be transported and placed on the container.

To hold the plug in the cap are in the WO 2007/063218 A1 Holding pieces proposed which surround the plug in the circumferential direction and pinch. In this case, a flat surface at the upper portion of the plug on a mating surface of the cap come to rest.

A disadvantage here is that the plug can not be sufficiently cleaned or sterilized when the closure is seated on the container. Since the flat surface abuts a mating surface of the cap, the vapor can not reach this flat surface sufficiently. Furthermore, it is disadvantageous that the plug can fall out of the cap when transporting the closure, if the clamping action of the cap is not sufficient.

From the US 5,819,964 and from the DE 297 10 136 U 1 a closure for a container according to the preamble of claim 1 is known in which the plug is held captive in the cap, wherein the cap is fixable in two positions on the container, wherein the plug in a First position is spaced from the container and closes the container opening in a second position.

In the from the US 2001/0020607 A1 known closure the plug is held captive in the cap.

The invention has the object of providing a closure of the type mentioned in such a way and further, that a guide or centering of the closure is ensured when pressed onto the container.

According to the invention, this object is achieved with the features of patent claim 1.

Thereafter, a closure for a container of the type mentioned is characterized in that the cap has on the inside clamping elements, which are in particular formed as axially extending, projecting into the interior webs.

According to the invention, it has first been recognized that a latching of the plug by the holding pieces connects the plug to the cap in a captive manner. By the axial fixation of the plug in a predetermined position can be achieved that a sterilizing agent can flow around the plug so that it is sufficiently cleaned. It is possible to sterilize the cap and stopper together. The fixation of the plug in a predetermined position prevents individual surfaces or regions of the plug from abutting the cap in such a way that the sterilizing agent can not reach these surfaces or areas. In addition, the cap can be transported together with the plug, which is inserted into its interior, to a container. The closure can then be placed on the container and placed in a drying position.

According to the invention, the container is largely protected against the ingress of contaminants when the closure is in the drying position. In the drying position, the drying of the previously introduced into the container substance can take place. It is conceivable to dry the substance by means of freeze-drying under the application of reduced pressure and temperatures below freezing point. In that regard, a closure is specified, which captures the container sealing plug captive and can be sterilized or dried together with the container and the substance contained in this.

The formation of clamping elements allows a guide or centering of the closure when pressed onto the container. Furthermore, the clamping elements create a clamping action by which the cap is pressed in the drying position against the container edge.

The holding pieces could be designed as tabs, which are articulated elastically on the inside of the cap. By this specific embodiment, it is possible to insert the plug in the axial direction in the cap, that the tabs are pressed in the radial direction to the outside. After the plug has passed the tabs, these can jump radially inwardly due to their elastic linkage and engage behind the plug.

Against this background, it is conceivable that at least two tabs are arranged equidistantly on the circumference of the inside of the cap as holding pieces. The equidistant arrangement allows a uniform locking of the plug. It has been found that four tabs are particularly advantageous for correct positioning of the plug in the cap.

The cap could have at least one spacer which projects into the interior and cooperates with the holding pieces in axially fixing the plug. The spacer ensures that the plug is fixed in a predetermined position that allows the plug to flow around. It is prevented that the plug rests with a larger surface on a mating surface of the cap.

The spacers could be formed knob-shaped against this background and protrude in the axial direction from the inside of the cap into the interior. Due to this specific embodiment, a flat surface of the plug can be punctured against the inside of the Cap are supported. A sterilizing agent, e.g. As steam, or a cleaning agent can wash around the knob-shaped spacers and the plug together. The selective placement of the flat surface of the plug on the spacers minimizes the area not reached by sterilizing agents or cleaning agents.

The cap could be latched with a plug having a sealing portion and an upper portion that is flared over the sealing portion. Such a plug is particularly suitable for insertion into a narrowed container neck of the container. The sealing portion may sealingly abut the container neck of the container, wherein the upper portion may come to rest on an enlarged container edge of the container sealing. Furthermore, due to its widened upper section, such a stopper can be locked captively with the holding pieces when it is transported to the container and held thereon in a drying position.

Against this background, it is conceivable to manufacture the plug made of rubber or thermoplastic elastomer. Advantageously, the plug should withstand temperatures of minus 50 ° to 121 °. The extremely low temperatures occur during the freeze-drying of a substance in the container. Sterilization by steam can reach temperatures of 121 ° C and more.

The upper portion of the plug could lie between the holding pieces and the spacers, wherein the holding pieces engage behind the upper portion and wherein the sealing portion protrudes axially. By this specific embodiment, the closure can be transported to the container, wherein the plug in the cap is taken captive. Furthermore, the axially projecting sealing portion can be inserted into the container neck of the container.

The plug could have a sealing portion, in whose lateral surface a slot-shaped recess for forming a passage is formed. The slot-shaped recess ensures that there is a flow connection between the container interior and the atmosphere when the closure is placed in a drying position on the container. The slot-shaped recess forms a passage when the sealing portion of the plug protrudes into the container when the closure is placed on the container. Such a slot-shaped recess is not necessary if the sealing portion of the plug is so short that it does not protrude into the container neck when the closure is placed on the container. In this case, there is a passage between the container rim and the lower end of the plug, which does not protrude into the container neck.

The cap could have on the inside of clamping pieces for latching behind a container edge. By this specific embodiment, the closure can be pressed onto the container and permanently connected to the container.

Against this background, it is conceivable that the clamping pieces are designed as tabs, which are articulated elastically on the inside of the cap. By this specific embodiment, the container neck can be introduced together with the container edge in the axial direction in the cap and press the tabs in the radial direction to the outside. After the edge of the container has passed the tabs, these can spring back due to their elastic articulation to its original position and engage behind the edge of the container. At the periphery of the inside of the cap could be arranged equidistantly as clamping pieces at least two tabs. Four tabs have proven to be particularly advantageous to permanently connect the closure firmly to the container. The equidistant arrangement of the tabs ensures a circumferentially uniform contact pressure of the closure to the container. The clamping pieces can also serve as a stop when the closure is in the drying position on the container.

The cap could have a tamper-evident closure, which is hinged to the cap to release a puncture site for a hypodermic needle. Through the tamper-evident closure, the consumer can be given the information that the container is in intact condition. Only after tearing off the tamper-evident closure is the puncture site accessible for an injection needle. The puncture site can be protected from contamination by the tamper-evident closure.

The cap could be a support member for biasing a handle portion of the tamper-evident closure. By this specific embodiment, it is possible to easily grasp the handle portion, for example, with a thumbnail and deduct the tamper-evident closure.

Against this background, it is conceivable that the cap has first cap openings which break through the lateral surface of the cap. The first cap openings allow demolding of the injection-molded cap. Further, a first cap opening may serve to receive the handle portion of the tamper-evident closure. By this specific embodiment, the handle portion, which opens into the first cap opening, are particularly easily taken by a consumer.

The cap could have second cap openings which break through the lid of the cap. These cap openings serve to facilitate removal from the injection-molded cap.

However, the first and second cap apertures serve not only to facilitate demoulding of the cap after injection molding, but also to allow passage of steam or sterilant during sterilization of the cap and / or escape of gaseous constituents from the container when the cap is in place Drying position is located on the container.

Against this background, it is conceivable that the cap is made of a plastic. A plastic can be used to make the cap in one piece by injection molding. Against this background, it is conceivable that the cap is made of polypropylene or HDPE. These materials have proven to be particularly temperature stable. The high temperature stability is necessary to withstand sterilization by heat or steam. Further, the use of a plastic allows the replacement of the aluminum caps known in the art. In normal sterilization, the plastic used must be at a temperature of at least 20 minutes Withstand 121 ° Celsius. Furthermore, the plastic used must withstand a very low temperature of -50 ° C for at least 24 hours. The same requirements apply to the material from which the plug is made.

A container could comprise a closure according to any one of the preceding claims. Such a container can be made particularly cost-effective while maintaining all sterility requirements.

Other objects, features, advantages and applications of the present invention will become apparent from the following description of embodiments with reference to the drawings. All described and / or illustrated features, alone or in any combination form the subject matter of the invention, regardless of the summary in individual claims or their dependency.
