Definitions

  • the invention relates to opening aids for ampoules, which ensure a safe and safe opening of the ampoules and at the same time a quick, loss-free transfer of the entire ampoule content into a vessel, for. B. allow a volumetric flask or a beaker.
  • the ampoules that can be opened are primarily plastic ampoules with concentrated solutions for the production of standard, standard and buffer solutions.
  • the most well-known opening aids for these ampoules are glass rods.
  • the glass rod In the sense of the device safety law, the glass rod is a device that carries dangers. When using the up to 30 cm long glass rods, they can break through for different reasons and the pressing hand gets into the splintered glass stump.
  • plastic-coated glass rods have a number of disadvantages: the runoff behavior of water and aqueous solutions is unfavorable; the casing can peel off at the glass / plastic transition point; these glass rods are disproportionately expensive.
  • plastic and metal rods are excluded from the cleaning agents used in the dimensional analysis (ethanolic potassium hydroxide solution or chromosulfuric acid) for repeated use.
  • the metal rod is also unusable for work in the field of trace analysis of metals, since it contaminates the standard solutions.
  • Another opening aid for ampoules on the market is a plastic knife.
  • this aid also has disadvantages: loss of the ampoule content because the knife cannot be rinsed off; Loss of ampoule contents when the ampoule opened on one side is turned over; if you place the volumetric flask on the ampoule before turning it around and turn both around together, there is a risk that the volumetric flask will break during this cumbersome operation; If the opening at the end of the ampoule is too small, the contents run out very slowly and there are difficulties when rinsing the ampoule.
  • the present invention has for its object to provide opening aids that allow rapid and quantitative emptying of the ampoule contents with little subsequent rinsing and with which the disadvantages described above do not occur.
  • the invention relates to opening aids for ampoules (2) sealed with plastic membranes (1), which are characterized in that they are designed as sleeves (3) which contain a device (4) designed as a cutting edge (5) on the inside.
  • the sleeves (3) preferably have the shape of a funnel, the device (4) being located in the tubular part of the funnel.
  • the device (4) is preferably designed as an inner tube which is connected at one end to the sleeve (3) either over the entire circumference or via webs (6).
  • the other end of the inner tube is chamfered both over the entire circumference and from the outside inwards and thus represents an effective cutting edge (5).
  • the cutting edges can also be welded to the plastic membrane (1) in such a way that the sleeve is already rotating (3) causes the plastic membrane (1) to tear.
  • FIG. 1 shows a preferred embodiment of the ampoule with the opening aids according to the invention.
  • Figure 2 shows a cross section through the sleeve (3), the webs (6) being recognizable.
  • the ampoule necks (8) and, accordingly, the associated sleeves (3) can have different diameters, preferably the neck (8) located at the outlet point of the ampoule has a diameter such that the ampoule contents are also in volumetric flasks Standard ground joint NS 14/23 can be emptied.
  • All parts of the ampoule and the opening aids according to the invention consist of plastics such as polyethylene, polypropylene, polyvinylidene difluoride or methylpentene polymers.
  • the dimensions can be chosen according to the desired amount of liquid.
  • a 100 cm 3 ampoule is z.
  • the ampoule body is provided with a thread (7) which, owing to its profile and its profile cross section, permits perfect and reliable guidance on the sleeve (3) provided with a corresponding counter thread. In this way, the rotary movement is converted into an axial movement.
  • the upper plastic membrane is preferably opened by being pressed in, the opening aid being guided in the axial direction as a sliding sleeve (3) on the ampoule neck (8).
  • the opening aid is also possible to provide the upper opening aid with a screw thread.
  • a guide groove can perform the same function as the thread.
  • the sleeve (3) contains an inner tube, the end of which is formed into a sharp-edged cutting edge (5).
  • This tube is preferably connected to the sleeve (3) at 2-6 points via webs, so that the contents of the ampoule rise up between the outside of the ampoule neck and the inner tube during emptying.
  • the opening aids can be placed conversely on the ampoule so that the cutting edge (5) faces away from the plastic membrane (1). If opening aids are used which convert a rotary movement into an axial movement via a thread (7), two circumferential annular beads on the tubular extension of the ampoule, which hold a corresponding bead in the plug-on funnel, can form a lock. This lock can be overcome by vigorous turning; an overcoming by vertically acting forces, such as. B. when the ampoule falls, is not possible. Other options for securing transportation are e.g. B. bayonet catches or a tear-off tab that must be removed before screwing in.
  • the opening aid according to the invention ensures a safe opening of the ampoule and a quick, complete and loss-free transfer of the ampoule contents into a volumetric flask or into a beaker. No further aids, which may be dangerous or impair the contents of the ampoule, are required to open the ampoule.
