Definitions

  • the present invention relates to an ampoule for liquids which is closed with a stopper which is connected via webs to a sleeve which is placed over the neck of the ampoule.
  • Concentrated solutions for the production of measurement, standard or buffer solutions for measurement analysis are usually supplied in ampoules. If necessary, the ampoules are opened, the contents are placed in a volumetric flask and filled with water.
  • a critical point is the opening of the ampoules.
  • the most well-known opening aids are glass rods, which must be up to 30 cm long. These can break through for various reasons and cause injury.
  • plastic and metal rods are excluded from the cleaning agents used in measurement analysis, such as chromic sulfuric acid or alkaline solutions, for repeated use. A metal rod would also contaminate the solutions, which would therefore no longer be used in trace analysis of metals.
  • Another known opening aid is a plastic knife.
  • the disadvantage of this is that it cannot be rinsed off and the contents of the ampoule can be lost. The latter can also happen when the ampoule is opened on one side. If, on the other hand, you place the volumetric flask on the ampoule before turning it around and turn both together, there is a risk that the volumetric flask will break during this cumbersome operation. In addition, if the opening on the ampoule is too small, the content drains very slowly and there are difficulties in rinsing the ampoule.
  • ampoules with a twist lock which is welded to a membrane are already known.
  • This version also has disadvantages, since the welding of the ampoule membrane with the closure can be damaged under extreme transport loads. Any leaked liquid makes the remaining content worthless. Dangerous goods fillings can also cause personal injury and property damage.
  • US-A-3 351 249 already describes a container, for liquids, which, however, is not to be regarded as an ampoule, consisting of a body, a neck and a stopper for closing the neck, in which the stopper is connected via webs with one over the neck slipped sleeve is connected, which in turn is connected to the body via a thread.
  • EP-A-332914 is described in EP-A-332914 as funnel-shaped sleeves for ampoules which contain a membrane welded to the plastic membrane of the ampoule, both membranes tearing when the ampoule is opened.
  • the object of the present invention is to provide an ampoule for liquids which can be opened and emptied in a simple and unproblematic manner without loss of content.
  • an ampoule for liquids consisting of ampoule body (1), ampoule neck (2) and stopper (3) for closing the ampoule neck (2), characterized in that the stopper (3) via webs (4) with a the ampoule neck (2) slipped sleeve (5) is connected, which in turn is connected to the ampoule body (1) via a thread (6) which the Ampoule neck (2) opposite end of the ampoule body (1) is welded to a plastic membrane (10) and the end of the ampoule body (1) welded to the plastic membrane (10) with an inverted funnel (11) into which a tip (12) with baffles (13) is integrated, is provided.
  • the stopper (3) advantageously has a slightly larger diameter than the opening of the ampoule neck (2).
  • the ampoule according to the invention preferably has an originality ring (7). This is connected to the ampoule body (1), for example via a bead (8) and to the sleeve (5) in the original state via several connections.
  • the ampoule according to the invention can be opened in a simple manner by screwing on the thread (6), the originality ring (7) on the bead (8) being simultaneously stripped off and the stopper (3) being pulled out of the ampoule neck (2).
  • the ampoule can then be emptied into a volumetric flask via the spaces (9) of the webs (4).
  • the lower diameter of the sleeve (5) is advantageously designed for emptying into standard volumetric flasks, for example those with NS 14/23 ground joints.
  • the tip (12) with baffle surfaces (13) is preferably connected to the funnel (11) via one or more webs (14).
  • the funnel (11) is removed, rotated and placed back on the ampoule. Punctures the tip (12), the plastic membrane (10) and, via the funnel (11), the contents of the ampoule can be completely transferred into a volumetric flask with the aid of washing liquid.
  • the washing liquid is preferably injected into the funnel (11) using a laboratory spray bottle. The jet of liquid is directed from the baffle (13) under the pierced membrane (10) so that the contents of the ampoule left behind can also be rinsed out.
  • the ampoules according to the invention preferably consist of plastic, with thermoplastically processable materials being particularly advantageous.
  • the ampoules according to the invention particularly preferably consist of polyethylene, polypropylene or polyvinylidene fluoride.
  • Figure 1 shows an ampoule according to the invention in the closed original condition.
  • the ampoule neck (2) On the underside of the ampoule body (1) there is the ampoule neck (2), over which the sleeve (5) is placed and which is screwed to the ampoule body (1) via the thread (6).
  • the tamper-evident ring (7) secures the connection.
  • the stopper (3) connected to the ampoule neck (2) via the webs (4) closes the ampoule.
  • the ampoule body (1) is closed on the top with the membrane (10).
  • the funnel (11) in which a tip (12) with baffles (13) is integrated, is placed upside down.
  • FIG 2 shows the ampoule according to the invention according to Figure 1 in the open state.
  • the connection between the ampoule body (1) and the sleeve (5) is screwed on, the tamper-evident ring (7) is stripped off by the bead (8).
  • the stopper (3) is pulled out of the opening of the ampoule neck (2) so that the ampoule can be emptied through the spaces (9) located between the webs (4).
  • the funnel (11) was placed rotated on the upper side of the ampoule body, the tip (12) penetrating the membrane. Washing liquid can be injected via the baffles (13).
