Definitions

  • the invention relates to a closure element according to the preamble of patent claim 1.
  • US-A-4,899,903 describes a closure element in the form of a tube closure which has a cap which can be broken off via a line of weakness. In both cases, the closure element is pushed onto a part of the hose or tube which is tapered in cross section, which results in the disadvantage that the hose or tube must be specially adapted to the closure element. Another disadvantage arises with regard to the breaking off process itself, since it is not ensured that the free hose or pipe end is not damaged by the breaking off process.
  • US Pat. No. 4,303,067 shows a closure element, in particular for a medical bag, which is welded between two bag films and has a breakable cap part.
  • the disadvantage here is that the breakable cap part is not protected against unwanted actuation, so that when handling the bag there is a risk that the cap part breaks off at the predetermined breaking point.
  • EP-A1-11 144 also shows a closure for a bag, in which a cap part or closure element can be separated from the connector part by means of a pull ring.
  • This is a solution in which the closure element is torn open.
  • the disadvantage is that on the one hand considerable forces are required for tearing open and on the other hand there is always the risk that the tear ring itself will tear off and / or the closure element will not be opened sufficiently. By applying a tensile force to open the closure, there is still the possibility that the remaining bag will be damaged or its contents may leak out in an undesired manner.
  • AT-PS 322 113 describes a medical container, the dispensing opening of which is closed with a conical cap. The cap is pushed over the dispensing opening, no break-off arrangement is provided. It follows from this that sterilization and handling have many disadvantages.
  • a container with a breakable cap part is also known from WO 84/03436.
  • a closure element of the type specified in the preamble of claim 1 is known from US-A-4,915,704.
  • the closure element designed as a tube closure has a cap which closes the outlet opening of a connector part and which can be broken off via a line of weakness.
  • the known closure element also has a handle placed over the cap, which serves on the one hand as a protective cap and on the other hand as a calibration aid. The handle is held by the breakable part of the cap.
  • the disadvantage is that the ingress of contaminating particles into the interior of the connector after breaking off the cap part cannot be prevented.
  • the invention has for its object to provide a closure element of the type mentioned, which on the one hand allows undisturbed outflow of the fluid with simple and reliable handling and on the other hand prevents the penetration of contaminating particles or the like.
  • the closure element according to the invention is characterized by a number of significant advantages.
  • the closure membrane provides the possibility of continuing to seal the outlet opening of the hose or tube or of the container to the environment after breaking off the cap part. At least penetration of contaminating particles or the like is avoided, so that a fluid can flow out unhindered by the subsequent connection of the closure element to a connection element or the like.
  • This has the further advantage that there is no need for additional closure or valve elements in the interior of the container, hose or tube can be.
  • a detachable protective cap is applied over the cap part and at least part of the connector part.
  • This protective cap prevents the cap part from accidentally breaking off and also serves as a tamper-evident device.
  • the protective cap is screwed to the connector part by means of a thread. In this way, an easy and targeted loosening of the protective cap can be achieved without the risk that the operating personnel will accidentally break off the cap part when loosening the protective cap.
  • the protective cap it is also possible to couple the protective cap to break off the cap part when the protective cap is loosened, for example by means of an integrated mechanism or the like, so that the cap part is broken off when the protective cap is removed or unscrewed.
  • the closure membrane is designed as an elastic membrane. This can be made of rubber or the like, for example, so that the membrane can be pierced to remove the liquid.
  • the membrane can also have a slotted design, as a result of which the individual wings of the membrane open when a pouring or draining element is inserted and enable an unimpeded flow of fluid.
  • the connector part in the connection area of the cap part has a cylindrical recess of larger diameter than the channel-shaped recess into which the membrane is inserted and into which a pipe socket of the cap part can be inserted.
  • the pipe socket of the cap part thus squeezes the disk-shaped closure membrane, so that it does not have to be attached by additional measures.
  • a secure connection of the cap part to the connector part is ensured, which can be designed to be sufficiently tight to ensure an excellent seal during sterilization and in the sterilized state.
  • the closure element shown in FIGS. 1 and 2 can be connected to a hose or tube 12, the tube or hose 12 not having to be adapted to the closure element. Rather, the closure element comprises a tubular connecting tube 11 which is bevelled on its front side and which can be inserted into the hose or the tube. Adjacent to the connecting pipe 11 is a collar 13 which serves as a stop for a protective cap 7 to be described below.
  • the connecting pipe 11 has a free, central cross section, which is only slightly smaller than the cross section of the outlet opening 1 of the pipe or hose 12.
  • a cylindrical tubular area Adjacent to the collar 13, a cylindrical tubular area is provided on the closure element, which has a cylindrical recess 9, the diameter of which is larger than the diameter of the connecting tube.
  • the transition to the cylindrical recess 9 takes place via a shoulder 14, against which a disk-shaped closure membrane 6 can be placed.
  • a pipe socket 10 is inserted, which, as can be seen from FIG. 1, clamps the closure membrane 6 together with paragraph 14.
  • the pipe socket 10 is connected via a predetermined breaking point 4 to a cap part 5, which seals the outlet opening 1 or the central interior of the closure element to the environment and can be broken off if necessary.
  • a thread 8 is provided, which can be single or multiple threads.
  • the thread 8 serves to screw the protective cap 7 shown in FIG. 2 onto the closure element in order to cover both the cap part and the pipe socket 10 connected to it, and also the connector part 2 of the closure element and protect against damage.
  • the closure element according to the invention has the following advantages: the flow rate through the channel-shaped recess 3 of the closure element can be greater than 1.5 l / min. Furthermore, no parts required for sealing are provided which can penetrate into the outlet opening 1 in an uncontrolled manner and thus into the container, the tube or the hose. In particular, additional sealing elements can essentially be dispensed with, otherwise the particulate loading of the sealing elements is zero. Furthermore, the cap part 5 ensures a tamper-evident closure, so that it can be easily and immediately determined whether the closure element has already been opened. Since the connector part 2 has a connecting tube 11, the closure element can be connected to any container, etc.
  • FIGS. 3 to 6 relate to the closure element according to the invention. These embodiments differ from the embodiment of FIGS. 1 and 2 first in that an additional ring seal 15 is provided in order to seal the protective cap 7 against the connector part 2 when the closure cap 7 is screwed on. This seal makes it possible to screw the protective cap 7 on tightly even after the cap part 5 has broken.
  • the tubular connector part 2 is provided with a flange 20.
  • the exemplary embodiments further show that the tubular Connector part 2 is connected in one piece to a foot element 17, the channel-shaped recess 3 of the connector part 2 opening into an inlet chamber 16 of the foot element 17.
  • the foot element 17 has a boat-like shape in plan view, it has two convexly outwardly curved side walls which converge at an acute angle on side edges 21, 22. The plate-like foot element 17 can thus be welded into the seam of a foil bag.
  • cap part 5 can be provided with corrugation or profiling in order to facilitate the breaking off process.
  • a filler neck 18 is also formed on the foot element 17, the interior of which is connected to the inlet chamber 16.
  • the filler neck 18 is sealed from the environment by means of a pierceable closure part 19.
  • the closure part 19 can, for example, as shown in Fig. 4, be in the form of a pierceable ball made of silicone or rubber. This is inserted into a cylindrical holder element 23, which is connected in one piece to the filler neck 18, and the ball is clamped by bending or flanging the edge of the holder element 23.
  • the foot element 17 can be made of polycarbonate or a similar material, for example, in order to facilitate welding into a foil bag.
