Definitions

  • the invention relates to a device for storing and dispensing a flowable substance according to the preamble of patent claim 1.
  • Such a device is known from EP 0 895 943 B1 and comprises a container which is formed from two films which define a first chamber for receiving the substance and a separate second chamber for applying the substance to a job instrument.
  • a pressure applied from the outside to the foils By means of a pressure applied from the outside to the foils, a predetermined separation point between the two foils can be released and thus a connection between the two chambers can be established, whereby the substance is applied to the application instrument.
  • the invention has for its object to provide a simple and safe to use device for storing and dispensing a flowable substance of the type mentioned in the introduction.
  • a device in which a first chamber is formed by a pot-like container which has in the region of its inner peripheral wall a radially inwardly projecting, sealing annular collar, and a second chamber is formed by a loading unit which has a in
  • the pot-like insert used comprises the container whose bottom limits the first chamber and on whose peripheral wall at least one transverse opening is formed.
  • the container and the insert can be brought by coaxial telescoping pushing from a closed storage position into an open release position. In the closed storage position, the bottom of the insert is spaced from the bottom of the container and the collar is positioned sealingly against the insert such that communication between the first chamber and the transverse opening of the insert is blocked.
  • the bottom of the insert In the open release position, the bottom of the insert is displaced in the direction of the bottom of the container as a result of the telescoping pushing together, that under reduction of the first chamber, the substance contained in the first chamber is conveyed through the transverse opening in the second chamber for acting on the applicator.
  • the rod-shaped application instrument is oriented substantially perpendicular to the axis of the insert and the container.
  • the device according to the invention is characterized in particular by its ease of use, as the unit container and loading unit are simply clamped between the index finger and the thumb of a hand and can be activated by a pressure then applied and the substantially rod-shaped application instrument by its right-angled orientation to the telescoping ergonomically favorable after exposure to the substance by means of the other hand separated from the rest of the device and can be used.
  • the application instrument is separated from the substance before activation of the system. This will prevent the job instrument from being affected qualitatively by prolonged exposure to the substance.
  • the device according to the invention can be used in many ways and is particularly suitable for use in the dental field.
  • the flowable substance is in particular a liquid.
  • the job instrument is, for example, a brush or a brush, such as a so-called microbrush.
  • a protective cover is provided which delimits the second chamber.
  • the protective cover is formed for example of a film, such as a PE-coated aluminum foil.
  • the protective cover is designed in the manner of a blister pack, so that it is therefore formed from a deep-drawn part and a cover film, wherein the assembly consisting of the container and the loading unit is inserted into a cup of the deep-drawing film.
  • the protective cover can serve to hold the applicator instrument and be designed to be tear-open or peelable, so that the applicator element of the protective cover which is acted upon by the flowable substance can be conveniently removed.
  • the application unit can also form an immersion tray or unit for the application instrument, so that it can be repeatedly immersed in the substance which is contained in the application unit after activation of the device.
  • the loading unit may comprise a bearing surface for the job instrument aligned at right angles to the axis of the insert and the container.
  • the bearing surface is formed by a stalk-like projection of the loading unit.
  • the support surface may have a groove-like cross-section.
  • the job instrument can also be stored in a pipe section of the loading unit.
  • the pipe section secures the application tool radially.
  • the application unit it is expedient for the application unit to have at least two inserts, each of which interacts with a container. In each of the containers, a component of the multi-component system is held before activation of the device. The components are then mixed after activation in the application unit.
  • the inserts can be arranged side by side and have parallel axes or also be arranged coaxially and opposite one another.
  • the closed storage position insert may have an annular groove that cooperates with the annular collar of the container.
  • a further specific embodiment of the device according to the invention can be designed such that it has a wall-type separating device, for example, which separates the application instrument from an admission space of the application unit and cuts it through with the substance in question for applying the application instrument or pierced by the order instrument.
  • the separator may be formed by the loading unit or the protective cover.
  • FIGS. 1 to 4 a device 10 for storing and dispensing a flowable substance A is shown, which is contained in the deactivation position shown in the drawing in a chamber 12 and the For example, for application in the field of dental medicine can be used.
  • the loading device 13 is designed pan-like and comprises a stick-shaped, a support surface forming storage area 27 for the applicator 14 and a cup-like insert 15, which is essentially a cylindrical peripheral surface and encloses a chamber 16 for acting on the applicator 14 with the substance A.
  • the stem-shaped bearing portion 27 has a substantially channel-shaped cross-section, so that the rod-shaped applicator 14 is secured laterally.
  • the insert 16 immersed in a likewise cup-shaped container 17, which encloses the chamber 12 for storing the flowable substance A and in the region of its inner wall has a radially inwardly projecting, sealing annular collar 18 which in the in Fig. 1 shown closed storage position engages in an arranged on the circumference of the insert 15 of the loading unit 13 annular groove 19, whereby a closed storage position is defined in which no connection between the chamber 12 of the container 17 and the chamber 16 of the loading unit 13 is.
  • the insert 15 on the periphery of two formed as transverse openings recesses 20A and 20B, on the activation of the device 10, a connection between the chamber 12 of the container 17th and the chamber 16 of the insert 15 is made so that the flowable substance 11 can flow from the chamber 11 into the chamber 16.
  • a protective cover 21 which is formed from an aluminum bottom foil forming a cup 22 and an aluminum cover foil 24 coated with PE.
  • a user takes the device 10 between an index finger and a thumb of a hand. Then, pressure is applied to the bottom of the container 17 and the bottom of the opposite side of the loading unit 13, so that the container is displaced in the direction of the insert 15 and a connection between the chambers 12 and 16 is made via the recesses 20A and 20B ,
  • the insert 15 in this case acts in the manner of a piston, so that the flowable substance A contained in the chamber 12 is displaced via the recesses 20A and 20B into the chamber 16 of the insert 15 and the application instrument 14 is charged with the substance A.
