Description

Technical area

The invention relates to a closure device, in particular for a container, in particular for medicine or the like, and such a container with a closure device.

State of the art

In the medical field in particular, it is known in the prior art that, in particular, liquid solutions or medicaments are received in containers as storage containers and patients are administered by way of treatment.

For this purpose, containers have become known in the art, which have a screw cap. For example, by the DE 692 08 561 T2 and the DE 32 21 164 A1 a closure device has become known in which a screw cap is provided for closing a container with a cylindrical opening. The screw caps are constructed in such a way that they are oiled so-called childproof and can only be screwed onto the lid under axial pressure. This requires a very complicated lid mechanism. However, such covers are not removable, if they have already been opened.

Also, the issue of tightness of such covers is difficult to answer if the lid is not properly closed. It is difficult for the user or operator to determine if the closure device is turned far enough to be sealed.

In addition, screw caps are through the DE 101 55 578 B4 become known, in which a tamper-evident ring is provided to indicate that the cap was either still unopened or has already been opened at least once. The construction of the closure lid with tamper evident ring is very complex and therefore cumbersome and expensive in terms of production costs and price.

Furthermore, it is very disadvantageous, in particular in the case of closure caps with tube connections, when the closure cap has to be rotated, because this causes the tubes attached to the closure cap to be twisted and optionally twisted together if more than two tubes are provided.

The 1 shows a closure device 1 a container 2 , The closure device 1 has with a lid 3 with a substantially flat base area 4 , a substantially cylindrical edge region 5 and a radially extending circumferential flange 6 on. The container has a flange 7 on which with the flange 6 comes into contact when the lid 3 on the container 2 is put on. To close the closure device is a clip 8th over the two flanges 6 . 7 pushed, so that the U-shaped receiving area 9 the two flanges 6 . 7 absorbs and thus secures the lid on the container. The recording area 9 is as U-shaped profile with two approximately parallel legs 10 . 11 and one the two thighs 10 . 11 connecting thighs 12 designed. In the end areas 13 . 14 the clip are recording means 15 for receiving a fuse element 16 intended. In the embodiment of 1 are the receiving means 15 as openings in the end areas 13 . 14 provided, so that as a fuse element, for example, a string 16 can be pulled through, which can be sealed so with a seal that opening the clip can be completed only with destruction of the seal.

The lid 3 has not shown connection areas for connecting, for example, hoses 17 . 18 , wherein in the embodiment of the 1 on the hose 18 a filter element 19 is provided. Inside the lid may also be provided a connection area for connecting hoses, but then in the container 2 protrude into what is in the 1 but not visible. The lid 3 indicates at its cylindrical edge region 5 a structure on, as in the manner of a gear, which serves the better handling of the lid.

The clip 8th has a part-circular shape, for example, in the range of about 270 ° C or more, with respect to the opening of the pitch circle, a handling element 20 connected to the clip to better push the clip onto the flanges.

The 2 shows the subject of the 1 again in another perspective view. The container 2 is approximately cylindrical with a provided in the upper region arrangement of the flange 7 , Will the lid 3 with its flange 6 on the flange 7 put on the container, so the clip 8th be pushed over the two flanges. Subsequently, in the receiving means 15 the fuse element 16 be inserted and fixed so that is identifiable when the lid is already lifted off or at least the clip 8th was removed at least once.

The 3 shows the embodiment of the 1 and 2 on average. Here is the closure device 1 on the container 2 placed. The container is designed substantially cylindrical in its lower region, wherein in the area 21 a radius reduction takes place and into a cylindrical edge area 22 passes, from which the flange 7 protrudes radially outward. The lid with its cylindrical edge area 5 overlaps the cylindrical edge area 22 the container radially and axially, so that the flange 6 , which is arranged at the lateral end of the cylindrical edge region, with the flange 7 comes into contact. The axial end area 23 of the cylindrical edge region 22 occurs with a seal 24 in sealing contact to seal the container against the lid. The seal 24 is disposed between a contact area of the lid and a contact area of the container, wherein the contact area of the container is the axial end area and the contact area of the lid is a receptacle in which the seal is arranged or injected. Between the radial edge area 5 the lid and the bridge 26 is the recording 25 educated. The web stands in the axial direction of the base area 4 of the lid inside. The thus formed U-shaped receiving space serves to receive the seal 24 ,

Furthermore, it can be seen that the cover at its base not only outwardly projecting connection areas 27 but also inwardly projecting terminal areas 28 , These are advantageously designed as a hose connection piece, so that hose lines or the like can be connected to these connection areas.

The 4 shows a detail of 1 to 3 on average, especially the 3 , Here is the cylindrical edge area 22 of the vessel 2 to be seen, spaced from the axial end portion 23 the flange 7 protrudes radially. The lid 3 with its basic area 4 and its cylindrical edge area 5 overlaps the cylindrical edge area 22 of the container, leaving the flange 6 with its lower surface on the flange 7 comes to rest with its upper surface. The seal in the receiving space between the bridge 26 and the cylindrical edge area 5 is through the axial end 23 of the cylindrical edge region 22 charged so that it ensures the lid-container seal. The clip 8th with her U-shaped profile with the thighs 10 . 11 and 12 is on the flanges 6 . 7 deferred and embraces these. The inside of the thighs 10 and 11 is bevelled, like the bevels 30 . 29 demonstrate. This causes the stronger the clip 8th on the flanges 6 . 7 is postponed, the stronger the compression of the two flanges to each other.

The 5 shows again the arrangement of the seal 24 in the recording 25 , This is the footbridge 26 from the basic area 4 of the lid 3 formed projecting in the axial direction, so that between the web 26 , the basic area 4 and the cylindrical edge area 5 a U-shaped recording 25 is formed, in which the seal 24 , for example, as an O-ring or oval ring is added. In the recording 25 also grips the axial end 23 of the cylindrical edge region 22 of the container 2 and acts on the seal 24 in the recording 25 ,

The 6 shows a detail of 4 or the 3 , The two flanges 6 . 7 are in attachment and the bracket 8th with her thighs 10 . 11 and 12 is pushed onto the flanges. The slopes 29 and 30 act on the end areas of the flanges and on the clip 8th on the flanges 6 . 7 the clip engages until the flanges on the bevels 29 . 30 are pending and acted upon by these. By the spring action of the clip 8th , which is preferably made of plastic or metal, becomes the staple 8th pushed on the flanges in the radial direction inwardly pushed, so that a permanent application of force to the two flanges takes place in the axial direction towards each other.

The 7 shows a perspective view of the lid 3 with basic area 4 , cylindrical edge area 5 and flange 6 , where the connection areas 27 are formed as hose nozzle, which protrude axially from the base area and have two conical areas for pushing and fixing a hose. The conical areas 31 . 32 are preferably spaced apart to secure a deferred hose.

The 8th shows the clip 8th with her thighs 10 . 11 and 12 , which are U-shaped on average, as can be seen in the end. In the end areas 13 . 14 are recording means 15 provided by means of which a securing element can be fastened.

In a further embodiment of the invention, the receiving means can also be flat areas on which, for example, a film, a sticker or the like can be applied or glued.

In such a case could be detected by the destruction of the securing means when the clip has been pulled off once or the lid was opened.

The flange surfaces are preferably formed smooth so that they lie flat on each other. However, it could also be advantageous in a further embodiment if the flange surfaces which lie on one another, in particular of the two flanges 6 . 7 , Have a structure which engages, so that a rotation of the two flanges is ensured.

In a preferred embodiment of the invention, the seal may be arranged not only in a receiving space on the inside of the lid, but alternatively or in addition to such a seal, a seal between the two flange surfaces may be arranged. For this purpose, it may be advantageous if in a flange or in both flanges, a groove is introduced, in which the seal is arranged. This seal could then be inserted into the groove or in the grooves or molded onto the flange.

Alternative to the connection areas 27 . 28 could also have an opening in the base area of the lid 3 be arranged to be able to pass through such an opening a hose can.

The clip 8th with their bevels in the region of the legs of the U-shaped profile can alternatively also be provided with conical projections, elevations or other contours, in order to slide the clip onto the flanges 6 . 7 to cause an axial force of the flanges on each other.

The seal can be inserted as already mentioned above as an O-ring or oval ring in the recording. Alternatively, the seal may also be a molded part having an individual contour to be ideally received in the receptacle. Alternatively, the seal may also be formed as a two-component injection-molded element, wherein the lid is preferably designed as a plastomer or hard component and the seal made of elastomer or soft component.

Particularly preferred in the embodiment of the invention is that a defined seal by the arrangement of the seal and the application of the clip 8th he follows. The lid is placed on the container 2 put on and the clip 8th over the flanges 6 . 7 pushed, it can be assumed that the seal seals and the two flanges are properly set to each other. By securing the clip with a fuse element can be immediately recognized in a visual inspection, whether the container has been previously opened or not. The putting on of the clip 8th can be identified as a guarantee that the seal seals and the container is sealed.

Advantageously, the clip may be connected to a captive with the container. This can be a ring on the clip 8th be provided with a connection to the bracket so that the ring is slipped over the opening of the container and thus secures the bracket. Alternatively, the clip can also be connected to the lid. Thus, it is advantageous if the lid or the container with the clip is also formed in one piece, wherein between the clip and the lid or the container, a flexible web is present,
