Definitions

  • the present disclosure relates to a medical fluid container with a resealable cap.
  • resealable fluid containers with a screw cap and a seal on the cap are used.
  • Known fluid containers essentially have the shape of a bottle and have a container connection piece for opening/pouring onto which the closure cap is screwed.
  • the seal is a sealing ring or tamper-evident ring that breaks when the cap is screwed on. Due to the thread stroke when screwing on the cap, the sealing ring is pressed against a defined retaining geometry and breaks.
  • the seal serves as a means of control to indicate that the fluid container has not been unscrewed or manipulated since it was manufactured/filled.
  • the known fluid containers also have a sealing insert in the closure cap.
  • the sealing insert extends into the interior of the container connection piece in the form of a plug and seals the fluid container.
  • the fluid container with the closure cap has two different seals.
  • an end face of the container connecting piece forms a surface pairing with a flat surface of the sealing insert.
  • the two surfaces are pressed together by tightening the screw cap of the fluid container.
  • a peripheral surface of the sealing insert terminates with an inner surface of the container connecting piece.
  • the sealing insert points an excess size and is pressed into the container connection piece. The elasticity of the sealing insert and the fluid container makes it possible to assemble the two components despite the dimensional overlap.
  • the known fluid containers are manufactured by extrusion blow molding.
  • This manufacturing technique is not necessarily suitable for producing sealing surfaces. Therefore, the inner surface of the container connection piece may have irregularities.
  • the irregularities are due to manufacturing by extrusion blow molding.
  • the surfaces are not manufactured with as much precision as is necessary for a sealing surface. In particular, the flatness and roundness of surfaces is of insufficient quality to create sealing surfaces. Due to the possibly insufficient flatness of the inner surface of the inner channel, the inner surface may not be sufficient to function as a sealing surface between the inner surface of the container connection piece and the peripheral surface of the sealing insert. Since the inner surface may have unevenness and/or irregularities, a seal between the inner surface and the sealing plug may possibly leak.
  • the front seal After the tightening torque is removed, the front seal immediately loses contact between the contact surfaces. However, the sealing ring only breaks after a significantly greater opening distance. This eliminates the need for a front seal before the sealing ring tears off and is therefore irrelevant for security against manipulation. The seal on the inner surface of the container connection piece is too short to remain sealed over the opening distance covered when the closure cap is screwed on until the sealing ring breaks off.
  • the closure cap Even if the closure cap is opened only slightly, the primary frontal seal is eliminated and the secondary seal on the inner surface of the container connection piece is not sufficient to reliably seal the fluid container. Furthermore, the fluid container can be opened or leaky before the sealing ring on the fluid cap breaks. I.e. in the worst case, the cap is only screwed on to such an extent that the sealing ring has not yet broken, meaning that the fluid container is still considered to be originally closed and liquid can still escape from the fluid container.
  • a fluid container with a closure cap is known, which can be screwed onto a container connection piece using a thread.
  • the closure cap has a sealing insert with a sealing plug, from the circumferential surface of which a sealing lip projects radially outwards.
  • the GB 2 026 995 A discloses a medical container that is closed by a cap.
  • the closure cap has a sealing insert with a sealing plug, from the circumferential surface of which a sealing lip projects radially outwards.
  • the object of the disclosure is therefore to overcome the disadvantages of the prior art and to provide a medical fluid container with a closure cap which improves the tightness of the fluid container.
  • the disclosure relates to a medical fluid container with a container connection piece and a closure cap.
  • the container connecting piece forms an internal channel through which the interior of the container is accessible from outside and has an external thread on a longitudinal section of the piece.
  • the closure cap is screwed onto the longitudinal section of the nozzle using an internal thread in order to close the fluid container and has a sealing insert.
  • a sealing plug protrudes from the sealing insert and protrudes into the inner channel of the container connection piece in such a way that a peripheral surface of the sealing plug is in sealing contact with an inner surface of the inner channel.
  • a single or several axially spaced circumferential sealing lips protrude radially outwards from the circumferential surface of the sealing plug.
  • the inner channel of the container connection piece has a receptacle for the sealing lip.
  • the medical fluid container is closed by the screwed-on closure cap.
  • the cap is screwed onto the container connection piece through a thread.
  • the closure cap has the sealing plug, which projects into the inner channel of the container connection piece and seals the inner channel.
  • the sealing plug has one or more sealing lips which protrude radially outwards from the peripheral surface of the sealing plug.
  • the inner channel therefore has a section which is intended and designed for the sealing lip to be received therein.
  • the material of the container connection piece settles due to a sterilization temperature during the sterilization process.
  • the pressure that the sealing lip exerts on the inner surface of the inner channel during seating causes the inner surface to be deformed. It forms a receptacle for the sealing lip.
  • the sealing lip may seal the inner channel more poorly.
  • the primary seal loses or reduces its sealing effect. If the cap is unscrewed, the position of the circumferential sealing lip in the inner channel can also change.
  • the sealing lip no longer rests in the receptacle and can achieve its complete sealing effect again.
  • the recording can also prevent or at least reduce damage to the sealing lip. Since the fluid container is stored most of the time in a closed state, the sealing lip can be accommodated in the receptacle and is therefore subjected to less pressure. Only when (partially) opening the fluid container can a high pressure on the sealing lip and the associated high sealing effect be advantageous.
  • the fluid container When the cap is closed, the interior of the container is sealed not only via the sealing lip(s).
  • the fluid container also has a further seal between an end face of the container connecting piece and a flat surface of the sealing plug. The two surfaces are pressed together by the tightening torque of the screwed cap. This seal is the primary seal. However, if the cap is only partially or slightly screwed on, the tightening torque and thus also the sealing effect of the primary seal are eliminated. In this case, however, the one or more sealing lips prevent fluid from exiting the fluid container. This means that the fluid container is sealed even if the cap is not completely screwed on.
  • the closure cap also has a sealing ring.
  • the sealing ring is attached to or in the closure cap in a cohesive or form-fitting manner.
  • the sealing ring lifts with the closure cap due to the thread stroke.
  • the sealing ring breaks when unscrewed at a defined retaining geometry on the outside of the container connection piece. This makes it possible to determine whether the fluid container has already been opened or whether the fluid container is still open is originally closed.
  • the distance between the sealing ring and the retention geometry on the container connector defines a thread stroke that is necessary until the sealing ring breaks.
  • the receptacle is formed by pressing the circumferential sealing lip onto the inside of the inner channel.
  • the circumferential sealing lip can have such an excess that it presses/presses against the inside of the inner channel when the sealing insert is inserted into the container connection piece. This ensures good sealing ability.
  • the container When the sealed fluid container is sterilized, the container may be subjected to a high sterilization temperature.
  • the plastic from which the fluid container is preferably made can deform (minimally) due to the sterilization temperature.
  • the circumferential sealing lip can press into the inside of the inner channel. This forms the receptacle in the inner channel.
  • the primary seal loses its sealing ability.
  • the sealing lip is moved out of the receptacle by the thread stroke. Since the inner channel towards the end face has a smaller inner diameter than the receptacle or is not deformed, the sealing ability of the sealing lip is greater when the closure cap is screwed on than in the screwed state. The sealing lip seals the fluid container during the thread stroke.
  • each of the sealing lips is nose-shaped in a longitudinal section.
  • Each of the sealing lips has a (long) nose bridge, a rounded nose tip and a (shorter) nose bridge when viewed in the axial direction from the end face of the container connection piece.
  • the rounded nose tip represents the sealing lip.
  • the nose tip touches the inner surface of the inner channel and forms a linear seal.
  • the radial extent of the sealing lip is larger than the inside diameter of the inner channel.
  • the sealing plug or the sealing lip are made of an elastic material. This means that the sealing lip can be pressed into the inner channel of the container connection piece despite its oversize.
  • the nose-shaped sealing lip has good sealing ability due to its geometry.
  • the axial extent of the bridge of the nose is greater than that of the bridge of the nose.
  • the sealing lip is preferably not (axially) symmetrical in its extension in the longitudinal direction. Rather, a side that is positioned closer to the end face as seen from the apex of the sealing lip can be longer than the side opposite the apex.
  • the sealing lip can be pulled out of the inner channel with less resistance than it can be pushed into the inner channel. This makes it easier to open/unscrew the fluid container. The sealing plug is manually pulled out of the inner channel.
  • the sealing surface between the sealing lip and the inner surface of the container connection piece is linear.
  • the linear sealing surface increases the surface pressure at the contact point and thus the potential for sealing the inner channel of the Container connection piece increased. Due to the higher surface pressure, manufacturing-related or settlement-related irregularities on the inner surface of the container connection piece can be compensated for.
  • the flat surface of the sealing plug which terminates with the end face of the container connecting piece, has a recess.
  • the sealing plug has the flat surface which, together with the end face of the container connecting piece, forms the primary or front seal. The two surfaces are pressed together by the tightening torque of the closure cap.
  • the recess is positioned on the flat surface in the radial direction on the outside.
  • burrs or fringes or inhomogeneities in the contour on the end face of the container connection piece. These come, for example, from the separation of the fluid container from the head piece.
  • the inhomogeneities can reduce the sealing effect of the two surfaces and are usually present radially on the outside of the end face.
  • the recess which is attached radially on the outside of the flat surface, accommodates any burrs or fringes that may be present. This means that the remaining surface of the flat surface can be pressed onto the end face of the container connection piece without the contaminants preventing direct contact.
  • the thread stroke when opening the closure cap, which causes the sealing ring to break, which is attached to the closure cap and indicates whether the fluid container is still originally closed is smaller than an opening path at which the fluid container is no longer closed and which is defined by the position of the sealing lip.
  • the distance between the sealing ring and the retaining geometry of the container connection piece defines the thread stroke that must be covered when screwing on the closure cap until the sealing ring breaks.
  • a distance is defined by the thread stroke until the sealing ring breaks.
  • the path for opening the fluid container is defined by the position of the sealing lip in the container connection piece. The sealing lip is therefore positioned away from the end face of the container connection piece in such a way that the sealing ring breaks before the fluid container is opened. This ensures that the fluid container is never open or that liquid can escape without the sealing ring being broken. The sealing lip therefore ensures that the fluid container is sealed until the thread stroke is so large that the sealing ring breaks.
  • the distance between the sealing ring and the retaining geometry does not necessarily alone define the thread stroke until the sealing ring breaks.
  • Several factors can play a role. Examples of these factors include deformation of the thread when setting after sterilization and any axial distances between threads of the internal and external threads.
  • an injection point of the sealing plug points towards the interior of the container.
  • the sealing plug is manufactured, for example, by injection molding. That is why the sealing plug has the injection point. There the melt is injected into the cavity and, after cooling, the sealing plugs are formed. Given the current state of technology, it cannot be completely ruled out that burrs or fine threads (particles) will form at the injection point.
  • any particles that may be present are outside the fluid-contacting part of the closure cap. Contamination of the fluid by these particles is therefore ruled out.
  • a closure cap of the medical fluid container has the sealing insert with the sealing plug, which protrudes into the inner channel of the container connecting piece in such a way that an inside of the inner channel is in sealing contact with one Circumferential surface of the sealing plug stands.
  • a single or several axially spaced sealing lips protrude radially outwards from the circumferential surface of the sealing plug. The cap closes the fluid container.
  • the sealing insert of the closure cap seals the fluid container.
  • the present disclosure further relates to a method of producing a medical fluid container according to any of the above aspects.
  • the manufacturing process has the following steps.
  • a medical fluid is filled into the medical fluid container.
  • a sealing insert is introduced into a container connection piece of the medical fluid container forming an inner channel (6), so that a circumferential sealing lip of the sealing insert presses against an inner wall of the inner channel.
  • a closure cap is screwed on using an internal thread, which can be screwed to an external thread on a longitudinal section of the container connecting piece.
  • the sealed medical fluid container (including its contents) is sterilized.
  • the circumferential sealing lip forms a receptacle in the inner wall of the inner channel due to a sterilization temperature during the sterilization process, in which the circumferential sealing lip is received in a form-fitting manner.
  • the mount can reduce the pressure on the surrounding sealing lip.
  • the sealing lip can protrude beyond an inner diameter of the inner channel and thus be pressed into the inner channel.
  • the holder can reduce this pressure without reducing the sealing effect, since when the cap is completely screwed on, the primary seal seals the fluid container. Only when the cap is (partially) screwed on does the primary seal no longer apply and the sealing effect of the sealing lip is required. The sealing lip can then be moved out of the receptacle by the thread stroke and can therefore develop its maximum sealing effect.
  • Fig. 1 shows a sectional view through a fluid container 1 with a closure cap 2 according to the prior art.
  • the fluid container 1 has a container connection piece 4, which forms an inner channel 6 and via which a container interior (not shown) is accessible from outside.
  • the container connecting piece 4 has an external thread 10 on a longitudinal section 8 of the piece.
  • the fluid container 1 also has the closure cap 2.
  • the closure cap 2 has an internal thread 12 and is screwed onto the external thread 10 of the container connecting piece 4 in order to close the fluid container 1.
  • the closure cap 2 has a sealing insert 14 with a sealing plug 16 protruding from a base surface of the sealing insert 14.
  • the sealing plug 16 extends into the inner channel 6 of the container connecting piece 4.
  • the sealing plug 16 has a larger outer diameter than the inner diameter of the inner channel 6 and is therefore pressed into the inner channel 6 with an oversize. Due to this excess, the sealing plug 16 seals the inner channel 6.
  • the sealing insert 14 also has a flat surface 18 which extends radially outwards from the sealing plug 16.
  • the flat surface 18 rests on an end face 20 of the container connecting piece 4. Through the (screwed) Closure cap 2, the flat surface 18 is pressed onto the end face 20. When the closure cap 2 is completely screwed to the fluid container 1, a tightening torque of the closure cap 2 is greatest and the pressure on the flat surface 18 and the end face 20 is maximum.
  • Fig. 2 shows a sectional view through a bottle mouth or the container connection piece 4 of the fluid container 1 according to the disclosure with the closure cap 2.
  • the fluid container 1 contains the front-side container connecting piece 4 with the external thread 10. Further towards the interior of the container, the fluid container 1 has a retaining geometry 21 in the form of an edge. After the retention geometry 21, the fluid container 1 expands into a bottle shape.
  • the inner diameter of the inner channel 6 is larger than the outer diameter of the sealing plug 16.
  • the container connecting piece 4 has an end-side projection 22 (in Fig. 3 shown) in the direction of the inner channel 6. Viewed in the direction of the inside of the container, the inner channel 6 has a shoulder, whereby the inner diameter of the inner channel 6 is larger than the inner diameter of the front projection 22.
  • the sealing plug 16 rests on the front projection 22, between an inner surface of the inner channel 6 after the projection and the Sealing plug 16, on the other hand, has a distance.
  • the sealing plug 16 has a circumferential sealing lip 24 which projects radially outward from a peripheral surface of the sealing plug 16. The design of the sealing lip 24 is in Fig. 3 presented in more detail.
  • a sealing ring 26 is attached to the closure cap 2.
  • the sealing ring 26 can be attached to the closure cap 2 in a cohesive, positive or non-positive manner.
  • the closure cap 2 is a lid and has a circumferential side wall 28, on the inside of which the internal thread 12 is attached.
  • the sealing ring 26 is attached to an end side of the side wall 28 that faces the container interior.
  • the sealing ring 26 has a fastening section 30 which is formed parallel to the side wall 28 and is designed to fasten the sealing ring 26 to the closure cap 2.
  • the sealing ring 26 also has an undercut section 32.
  • the undercut section 32 is positioned behind the retaining geometry 21 of the container connecting piece 4.
  • the undercut section 32 is spaced from the retaining geometry 21.
  • the fastening section 30 and the undercut section 32 are connected by a thin predetermined breaking web 34.
  • the closure cap 2 When the closure cap 2 is unscrewed from the fluid container 1, the closure cap 2 and with it the sealing ring 26 are raised by a threaded stroke. The undercut section 32 is pressed against the retaining geometry 21 by the thread stroke. The thin predetermined breaking web 34 tears off. The thin predetermined breaking web 34 is therefore a predetermined breaking point. As a result, the sealing ring 26 is damaged when the closure cap 2 is unscrewed and thus indicates that the fluid container 1 has been opened. The sealing ring 26 therefore functions as a seal for the fluid container 1.
  • Fig. 3 shows a section of the sectional view in Fig. 2 .
  • the sealing lip 24 is essentially nose-shaped and has a frontal nose bridge 36, a rounded nose tip 38 and a nose bridge 40 in the axial direction.
  • the nose bridge 36 is longer than the nose bridge 40.
  • the sealing lip 24 has the largest radial circumference.
  • the outer diameter at the nose tip 38 is larger than the inner diameter of the inner channel 6. Since the sealing lip 24 is made of elastic material, the sealing lip 24 can be pressed into the inner channel 6.
  • the sealing lip 24 deforms and forms a substantially linear seal.
  • the inside of the inner channel 6 has a receptacle 41 for the sealing lip 24.
  • Recording 41 will be formed, for example, when the fluid container 1 is sterilized and the container connecting piece 4 and the inner channel 6 deform by being subjected to a sterilization temperature.
