Definitions

  • the invention relates to an infusion bottle in which a push-through part for an infusion spike is provided in the region of the mouth, the push-through part being made of a thermoplastic material and provided with at least one integrally molded sealing lip which can be expanded by the infusion spike.
  • Such an infusion bottle is known from DE-OS 41 03 041.
  • the closure cap and the infusion bottle are made of plastic, the closure cap having a double-walled lid area with an outer wall as a tear-off part and the inner wall being designed as a cannula push-through part.
  • the cannula push-through part is provided with an essentially circular opening, which surrounds a cannula of larger diameter with an elastic lip sealingly on the circumference.
  • the infusion bottle is inexpensive to manufacture in terms of production technology and economy, with all parts used being made of a plastic and being recyclable together. It should be noted, however, that the lip touches the cannula in a largely linear manner, which can lead to damage to the sealing edge as soon as the cannula is inserted into the infusion bottle.
  • Leaks can then be expected during the intended use.
  • the cannulas with which the content is removed from the infusion bottle must always have a substantially matching outer diameter, since only very small diameter tolerances of the cannulas can be compensated for without the seal deteriorating.
  • the invention has for its object to further develop an infusion bottle of the known type such that the sealing lip ensures an improved sealing result on the outer circumference of the cannula, even if cannulas with different outer diameters are used.
  • the radial contact pressure with which the sealing lip encloses the cannula on the outer circumference should then also be of essentially the same size.
  • the push-through part of the infusion bottle is provided with a sealing lip which is formed on its radially inward-facing side by a cylinder section, the cylinder section having an inner diameter which essentially corresponds to its length and the cylinder section and the push-through part are connected by an intermediate ring , which has a substantially Z-shaped profile. It is advantageous here that the content of the infusion bottle can be removed through cannulas with different outer diameters without fear of disadvantages with regard to the sealing in the area of the outer circumference of the cannulas. Starting from an average outer diameter of the cannula, diameter deviations of ⁇ 25% can be compensated for by the design of the sealing lip without leakage occurring in the area of the sealing surface between the sealing lip and cannula.
  • the sealing lip Due to the Z-shaped intermediate ring, the sealing lip is resilient in the radial direction, the radial contact pressure of the sealing lip on the outer circumference of the cannula to be sealed always within the tolerance range is substantially the same size.
  • the risk of damage to the sealing lip when inserting the infusion spike is minimized by the configuration of the sealing lip as a cylinder section, so that particularly simple handling and the good performance properties are of particular importance.
  • the cylinder section and the intermediate ring can have an essentially matching wall thickness. Particularly in the area of the transitions between the sealing lip, which is formed by the cylinder section, and the intermediate ring, essentially matching wall thicknesses necessitate production without different shrinkage stresses within the push-through part. The material load is thus evenly distributed within the push-through part.
  • the intermediate ring can be connected to the cylinder section and the push-through part in the region of the ends opposite each other in the axial direction.
  • the infusion spike is particularly easy to insert into the infusion bottle if the cylinder section is conically narrowed in the direction of the infusion bottle. This configuration requires centering when inserting the infusion spike into the infusion bottle, so that damage in the area of the sealing lip which is essential for the seal is reliably avoided.
  • the cylinder section is preferably connected to the intermediate ring on this side, the intermediate ring being connected to the push-through part on the side facing away from the infusion bottle.
  • a good seal of the cannula on the one hand and a sufficiently large elastic resilience in the radial direction with a reliable fixing of the sealing lip within the push-through part is achieved according to an advantageous embodiment if the profile of the intermediate ring in the area of the ends is substantially perpendicular to the imaginary axis of the Cylinder section extends. Radial displacements of the cannula and thus the sealing lip are absorbed by the intermediate ring in the area of the ends, and in connection with the essentially matching wall thicknesses of the cylinder section, intermediate ring and outer circumference of the push-through part even with a large number of load changes, due to radial and axial displacements of the cannula within the push-through part there is no fear of deterioration in the properties of use.
  • the profile of the intermediate ring extends between the ends preferably essentially parallel to the axis of the cylinder section.
  • the advantage here is that the intermediate ring is designed as a stop buffer and limits extreme deflection movements of the cylinder section and the cannula in the radial direction. This configuration minimizes twisting of the infusion spike in the area of the passage through the cylinder section and the infusion bottle, so that the cannula is securely held in the area of the sealing lip, for example, in an infusion bottle hanging with the bottle neck underneath.
  • the cylinder section can be arranged eccentrically within the push-through part.
  • the advantage here is that the cylinder section is offset to the seam of the infusion bottle, so that the bottom of the infusion surface is easier to pierce.
  • the push-through part can have, for example, three cylinder sections evenly distributed in the circumferential direction.
  • the advantage here is that, for example, several cannulas can be inserted into the infusion bottle. For example, if only one cannula is to be inserted, at least one cylinder section lies outside the seam of the infusion bottle and can therefore be pierced with less effort.
  • the closure cap 9 is double-walled and comprises on the side facing away from the infusion bottle a tear-out part 11 which can be removed from the closure cap 9 by a tear-out bracket 12.
  • an essentially disk-shaped push-through part 2 is arranged, which is fixed in the cap 9 in a liquid-tight manner.
  • the cap 9 and the Infusion bottles are made of plastic and are connected in a liquid-tight manner in the region of a collar 13, which is integrally formed on the bottle neck of the infusion bottle.
  • the liquid-tight connection in the region of the collar 13 can be produced, for example, by welding or gluing.
  • the infusion bottle, the cap 9 with the pull-out part 11 and the push-through part 2 are preferably designed as injection molded parts.
  • the pull-out part 11 is limited by a weakening line of relatively reduced material thickness.
  • the content from the infusion bottle can be removed by an infusion spike if first the pull-out part 11 is removed from the closure cap 9 and the cannula is then inserted through the sealing lip 3 of the push-through part 2 and then through the bottom 10 of the infusion bottle into the cavity.
  • the entire infusion bottle is made of the same material from thermoplastic, the push-through part 2 being provided with a sealing lip 3 which can be expanded by the infusion spike.
  • the sealing lip 3 is formed on the side facing the infusion spike by a cylinder section 4, which surrounds the inserted cannula in a sealing manner on the outer circumferential side under radial prestress.
  • the cylinder section 4 and the push-through part 2 are connected to one another by an essentially Z-shaped intermediate ring 5.
  • the cylinder section can have a slightly hollow-conical profile in order to simplify the removal from the mold.
  • the push-through part 2 is shown as an individual part in FIG. 2.
  • the cylinder section 4 is conically narrowed along its axial extent in the direction of the infusion bottle. This results in a centering effect when the cannula is inserted and the sealing surface facing the cannula is protected from damage.
  • the cylinder section 4 By fixing the cylinder section 4 to the Z-shaped intermediate ring 5, the its end 6 facing the infusion bottle on the cylinder section 4 and its end 7 facing away from the infusion bottle on the push-through part 2 results in an elastic flexibility of the cylinder section 4 in the radial direction to compensate for diameter tolerances of the cannula.
  • the ends 6, 7 extend substantially perpendicular to the imaginary axis 8 of the cylinder section 4 and the intermediate ring 5 between the ends 6, 7 is formed essentially parallel to the axis 8.
  • cannulas with a diameter of between 3 and 5 mm can be used. Due to the design of the push-through part 2 and the flexibility in the radial direction, an approximately constant pressure of the cylinder section 4 in the radial direction on the cannula is ensured in this diameter range and a secure seal is required.
  • the cylinder section 4 is arranged eccentrically in the push-through part 2 such that the manufacturing-related seam of the infusion bottle in the region of its base 10 does not have to be penetrated by the infusion spike to be inserted.
  • the push-through part 2 from FIG. 2 is shown in a view on the side facing the infusion bottle.
  • the push-through part 2 is provided with stiffening ribs 14, 15, 16 which at least partially surround the sealing lip 3 on the outside. This simplifies the handling of the infusion bottle.
