Description

2 AT 501 748 B1

The invention relates to a container closure with a closure cap, which has an outer shell and an insert to form a receiving space for an additional medium, wherein a cutting means is provided which is movable between a first position and an engagement position and which upon movement into the engaged position Cut through the insert and open the 5 receiving space.

Both in the beverage and food industry, as well as in medicine, there is often the need to add an additional medium to the contents of a container immediately before use. In this context, it is known to keep the additional medium in a container Ver-io final separated from the contents of the actual container, so that the consumer has the opportunity to achieve by appropriate manipulation release of the additional medium, so that this with the content of the Can mix container. By way of example, the additional medium may be a flavorant which is arranged in the closure cap of a bottle and is added only immediately before use. 15 In this way it is possible to provide drinks that would not last long enough in the ready-mixed state.

In the pharmaceutical industry too, it is often necessary to mix a preparation of two or more components first immediately before use. It can be both antibiotics, cytostatics or other drugs, as well as calibration fluids for medical devices or the like.

In order to meet the above requirements, a variety of container closures, caps and the like have been developed. Known solutions are described in US Pat. No. 4,024,952 A, EP 1 550 619 A, WO 2004/113190 A, WO 2004/089777 A, WO 2004/024587 A or WO 02/36065 A.

It has been found that none of the above solutions meets all the criteria required for such a container closure, namely simple and cost-effective manufacturability, high process reliability, ease of use, protection against counterfeiting, and largely independence from the media to be stored or produced.

In particular, for medical use, it is necessary to avoid any contamination of the container contents. This not only implies sterility of the components involved, but also a design that ensures that neither macroscopic nor microscopic components of the container closure are released when it is opened or released.

The object of the present invention is to provide a solution which meets all the above requirements optimally.

According to the invention it is provided that the insert consists of an axial holding part and a membrane which is integrally formed on the axial holding part, that the holding part is centrally connected in the upper area with the outer shell and that an annular cutting element is vorgese-45 hen, the trained is to shear the membrane at its outer periphery.

Essential to the present invention is to provide a closure which consists of a few components and has a simple structure. In general, the cap will consist of only three parts, namely the outer shell, the insert and the cutting element so. The inventive design ensures that the container contents can not be contaminated by detached parts of the cap.

The container closure according to the invention can not only be used for mixing of factory-produced ingredients, but is also suitable for connecting samples, such as urine samples, which are filled by the user into the container, to a reaction medium which is kept airtight in the container closure to allow analysis.

A particularly simple and cost-effective production is achieved when the insert is pressed into the outer shell. In general, this will be done in two places, namely at the upper end of the axial holding part of the insert, as well as on the outer circumference of the membrane. Now, if the axial holding part of the insert at the distal end of the membrane has a substantially cylindrical holding portion which is fixed in a hollow cylindrical receiving portion which is formed on the inside of the outer shell, and when the retaining groove opens in the use position down, is achieved that can be pressed by a single insertion movement during manufacture of the insert in the outer shell. This ensures a particularly simple production.

A particularly simple and structurally favorable embodiment variant results if the annular cutting element is slidably guided in the axial direction in the outer shell. Axial grooves can additionally prevent co-rotation in a disturbing for the separation extent. Initially, the axial movement of the cutting element is preferably prevented by a retaining lug or a plurality of retaining lugs, in order to prevent unintentional puncturing of the membrane. Only after overcoming a resistance, the retaining lugs 20 are deformed and the cutting element can perform the intended stroke to cut the membrane. In this way, the required pressure force is applied to overcome the resistance of the retaining lugs by the end face of the container opening, which presses on a bearing surface of the cutting element. The actuation thus takes place in that the closure cap is screwed against an increased resistance to a container 25 to be closed. In a particularly preferred manner, the support surface is simultaneously formed as a sealing surface which seals the closure cap against the container to be closed.

It is particularly advantageous if the cutting element has two mutually opposite recesses, that is, that it does not extend over the entire circumference, but has interruptions of the cutting edge at diametrically opposite points. Now, if the membrane is severed, remain in this way two relatively narrow webs, so that the membrane is not only connected to the holding part, but is also held over the webs. The membrane opens in this embodiment in the form of two approximately semicircular two sections, which fold down and release the receiving space. It has been found that in this embodiment, the risk is reduced that small parts of the membrane completely bare and contaminate the contents of the container. 40 A particularly reliable sealing of the container can be achieved in that the cutting element below has a circumferential sealing lip. The sealing lip protrudes approximately frusto-conical down and is in a closed container on the inside of the container opening. The particular advantage of this embodiment is that an increased internal pressure in the container supports the sealing effect. 45

A special stability with low wall thickness can be achieved in that the membrane is formed wavy in the radial direction. In this way, it is also possible to apply a bias in the radial direction in order to create as free as possible a connection between the interior of the container closure and the Behäl-50 ter after the membrane has been severed. Furthermore, it is of particular advantage when the membrane is biased, as this causes it to contract accordingly after cutting and the interior completely free. The bias can be made by stretching to 180% or more with proper material selection (e.g., SLR, i.e., liquid silicone rubber, silicone rubber). Alternatively, or in addition to the bias, a pre-fold may cause the membrane to fold after severing to further open the transition to the container.

Another particularly preferred embodiment variant of the invention provides that the axial holding part of the insert has an opening extending in the axial direction and that the outer shell preferably has a recess in the axial region. The opening extends from the bottom to the top of the axial holding part, but is not continuous. With this opening two major advantages can be achieved. On the one hand, it is possible to remove the container contents with a syringe by piercing the insert from above with a needle. The needle is inserted along the opening in the interior of the container. On the other hand, the production can be simplified by using a dome which is received in the opening when the insert is pressed into the outer shell.

Furthermore, it is particularly preferred if the insert and in particular the membrane is made of 15 SLR, fluorine silicone rubber or polymer or other materials which are sufficiently elastic and inert. In this way, unintentional opening or confusion can be reliably avoided. Thus, for example, it is possible in hospitals to variously distinguish different drugs or groups of drugs or other operating means, such as calibration fluids, irrigation fluids, or the like, in that various opening tools are required to open the individual containers. For example, all intravenously administered drugs could only be opened with a red tool.

Furthermore, it is preferred if the insert and in particular the membrane is designed as a functional part 25 and has a coating that influences a chemical reaction of the contents of the container and the closure. The coating may, for example, be in the form of a catalyst or luminescent in order to be able to carry out optical measurements. In the following, the present invention will be explained in more detail with reference to the embodiments illustrated in the figures. 1 shows a first embodiment variant of a container closure according to the invention in section, FIGS. 2a and 2b show a section along line II-II in FIG. 1, FIG. 3a and FIG. 3b shows a section along line III-III in FIG 4 shows a further embodiment variant of the invention, FIG. 5 shows a tool for opening a container closure 35 s of FIG. 4 and FIG. 6 a and FIG. 6 b shows a section along line V 1 -V 1 in FIG. 5 and FIG. 7 shows a detail of a further embodiment variant in an axonometric representation.

The container closure of Fig. 1 consists of a closure cap 1, which is composed of an outer shell 2, an insert 3 and an annular cutting element 4. The outer shell 2 has an upper top surface 5 and an upper cylindrical wall 6. A hollow cylindrical receiving portion 7 projects downwardly in the top surface 5 to receive the insert 3. At the lower end of the upper cylindrical wall 6, an annular retaining groove 8 is provided, which is also designed to hold the insert 3. Below this, a threaded portion 9 is provided, which is a screw thread 10 with which the cap 45 1 can be screwed onto the container, not shown here.

The insert 3 consists of an axial holding part 11 and a membrane 12, which is integrally formed thereon. In the upper region of the axial holding part 11, a cylindrical holding portion 13 is provided, which is pressed into the hollow cylindrical receiving portion 7. The membrane 12 is pressed with a thickened edge region 14 in the retaining groove 8.

By the upper top surface 5 and the cylindrical wall 6 of the outer shell 2, and the axial holding part 11 and the membrane 12 of the insert 3, a substantially annular receiving space 15 is limited, which is intended to receive an additional medium 55, not shown here. The annular cutting element 4 is slidable in the axial direction on a Gleitflä-

Several knob-shaped retaining lugs 17, which are supported on a shoulder 18 of the outer shell 2, initially prevent movement of the annular cutting element 4 upwards. After overcoming a predetermined compressive force exerted by the end face of the container on a support surface 19 of the cutting element 4 5, the retaining lugs 17 are elastically deformed and release the movement. In this way, a cylindrical cutting surface 20 of the annular cutting element 4 shears the membrane 12 in cooperation with a cylindrical inner surface 21 in its outer region. In the interior of the axial holding part 11 of the insert 3, an opening 22 is provided which opens downwards. This opening 22 facilitates the piercing of the insert 3 with a needle to remove the container contents via a syringe and makes it possible to facilitate the pressing of the cylindrical holding portion 13 in the hollow cylindrical receiving portion 7 in the manufacture of the cap 1. A recess 23, which is located centrally in the upper region of the outer shell 2, is a further relief for the piercing of the closure cap 1. A sealing lip 24 is circumferentially provided on the underside of the cutting element 4 in an inwardly projecting manner. In this way, the seal against the container, not shown, is improved. In Fig. 2b can be seen with 30 sensors that interact with the ingredients of the container or the cap 1 and thus allow the implementation of measurements. In the embodiment of Fig. 4 at the lower edge of the threaded portion 9, a locking ring 25 is provided, which makes it possible to determine whether the closure was in the original state, or whether the membrane is already separated. In contrast to the circlip in beverage bottles o. The like., This circlip 25 is designed so that it is blown up by the further screwing the cap 1 at the flared neck portion of the container. The embodiment variant of FIG. 5 is equipped with a turning tool 26 in the form of a cap. The twisting tool 26 has specific engagement surfaces 27 which are arranged on annular projections 28 to ensure a clear assignment of cap 1 and twisting tool 26. In this way, confusion can be largely prevented, since the twisting tools can be designed differently depending on the content of the container in color and shape. The cap itself is designed so that a twisting tool 26 is required in any case for proper opening. Fig. 7 shows a variant in which the membrane 12 remains connected via webs 29 with the periphery 40 of the closure. This ensures a central hold even in the separated state and it is possible to increase the filling level in the container. Claims 1.
