Definitions

  • the invention relates to a device for storing and dispensing viscous substances.
  • viscous in this context are all flowable, i. understood liquid to pasty substances, which may, for example, be gel-like.
  • the substances may be mixed in the application of at least two components.
  • the components themselves may also be viscous, but not all, but only at least one.
  • the viscous substances are, for example, adhesives or sealing materials, as used in dental technology.
  • the individual components are currently stored separately, for example, in bottles.
  • For use in the dental field are usually very small amounts, eg. Between 0.01 and 10 ml.
  • the dosage of such small amounts of substance is difficult, so that the desired mixing ratio is not accurate.
  • the substances are, after they are mixed, for example. With a brush or the like. Auxiliaries applied to the application site, whereby in addition, the risk of contamination of the individual components stored in the bottles arises.
  • a liquid container in the form of an elongate, flat bag is known, which is divided into two compartments.
  • the first compartment two superimposed and separate chambers are housed, in the second compartment a single third chamber, which is separated from the first two chambers.
  • the first two chambers are formed by two outer foils and a middle foil whose peripheral edges are sealed.
  • the first two chambers are filled with different liquids.
  • the third chamber which adjoins directly to the first two chambers and is formed by the two outer films of the first two chambers, contains no liquid.
  • the first two chambers merge into a tip facing the third chamber, the sealed edges of which have a lower bond strength than that of the sealed peripheral edges.
  • the container allows the mixing of at least two liquids, possibly also with a non-liquid substance.
  • a predetermined breaking point in the form of tear notches is provided in the edges of the two outer foils. By tearing off the end part of the third chamber at this point, the liquid content can escape from the third chamber.
  • This known liquid container should, for example, be used in the pharmaceutical sector or in adhesives. No contamination of the liquids or non-liquid substances can take place in the container because the peripheral edges of the container are hermetically sealed. By these tightly sealed peripheral edges and no leakage of liquids can be done.
  • two hands are required for emptying, since the container for discharging the liquid must be compressed flat, so that the liquid is not moved only within the container.
  • metering the amount of liquid discharged from the container is almost impossible.
  • EP 0 895 943 A2 is a device for storing and applying substances, preferably liquids in small quantities, known which comprises a container formed by two heat-sealed together films, the films together a chamber for receiving the liquid and a pocket for receiving a brush form. Between the chamber and the pocket a predetermined breaking point is formed in the connection of the two films, which is released by pressure on the chamber, so that the liquid can be pressed out of the chamber into the pocket and the tip of the brush located there can be wetted.
  • One of the two films may be a thermoforming film and the other film may be a cover film.
  • two chambers, a first and a second chamber may be provided for separately receiving different substances which are to be brought into communication with one another via a passage area to be selectively opened.
  • a connection to the second chamber is first made by pressure on the first chamber to mix the two components together.
  • the mixture leaves much to be desired.
  • the part of the device containing the deflated chamber is bent onto the second chamber so that the chambers on the cover sheet are in contact with each other lie and after pressure on the second chamber, the brush is wetted with the liquid mixture.
  • This device also has the disadvantage that the second chamber must be so large that it can accommodate the volume of both components. This either suffers from the component contained in the second chamber, because it is exposed during storage of the air, or the space above the second component must be filled or evacuated with an inert gas, which increases the manufacturing cost. To ensure that the bending process takes place at the right place, the two foils are drawn in laterally in the area between the two chambers. Due to the arrangement of the two chambers in series, they must be expressed one after the other. For all alternatives, nothing is mentioned about the way the components are filled. Because of the use of a brush as an applicator handling when applying the flowable substance on the application site is also possible only with two hands. In addition, manufacturing and storage of the device is complicated because of the brush required for applying the liquid mixture.
  • the device has a pocket, an applicator and at least one chamber with an indicator substance and possibly another chamber with a buffer substance, wherein the first chamber with the pocket and the possibly existing second chamber each with the first chamber and / or the Bag can be connected via a selectively open passage area.

  • the storage and spreading of larger amounts of substance to be made possible without the mixing result is impaired.
  • a dental bleaching system serving only for storage in which heated silica is to be used as the basis for the preparation of a paste with a hydrogen peroxide solution.
  • the paste serves as a non-reactive carrier to control the delivery of the hydrogen peroxide solution to a tooth surface.
  • the silica is initially contained in a predetermined amount in a mixing chamber, while the hydrogen peroxide solution in a predetermined volume taken in an ampoule. Both, the silica and the ampoule, are received in upwardly open recesses of a suitably deep-drawn support, which are covered for storage with a protective film.
  • a plastic packaging for the storage and delivery of active material which has several departments, which are intended for receiving liquid, solid or gelatinous material.
  • the compartments are formed by the connection of two flexible polymeric sheets so that there is at least one sealed storage compartment which is impermeable to the active material and a sealed receiving compartment.
  • At least one of the edges of the storage compartment is formed by a system which consists of an inner foam layer and adheres on its two outer surfaces to leak-proof flexible polymer films. External pressure on one of the compartments causes the foam layer to rupture without damaging the polymer sheets, thereby allowing the storage compartment to be emptied into the receiving compartment without exposing the active substance to the environment.
  • This plastic packaging is particularly useful for ready mixes of different components just prior to their use. It is not said how the storage compartment is filled and the active mixture is released from the package.
  • From the DE 31 22 237 A1 is a package for liquid filling material, consisting of a deep-drawn part and the deep-drawn from above tightly sealed cover sheet, in which there is a liquid medium and an insert for dispensing liquid in the space between the deep-drawn part and cover sheet.
  • the packaging has a predetermined breaking point, which is laid out so that when breaking off one part of the packaging from the remaining part of the insert is exposed, so that liquid are discharged through a passageway from the liquid space through the insert can.
  • This packaging is intended especially for use as disposable packaging or for samples. By suitable design of the insert (brush, sponge, dropper, stopper, etc.), the type and speed of the liquid delivery can be determined.

  • the peelbar sealed passageway also separates the chambers from each other. While the two chambers in the closed state of the device due to the sealed passage area have no connection with each other, a mixing of the two located in the chambers substances in the common dispensing area after opening of the passage area is possible.
  • the weakening of the passage area to facilitate the opening is done by a rotation of the chambers in the region of the chamber shoulder against a wing in the longitudinal direction of the Ausbring Schemees. After turning back to the initial position of the passage area is weakened so that even by slight pressure on one or both of the chambers opening of the passage area and thus a connection between the respective chamber or two chambers and the dispensing area can be achieved. It is also possible, if necessary, to apply only a portion of the amount of substance in the chamber due to reduced pressure on one of the chambers. As a result, for example, the mixing ratio of the two substances to be applied can be influenced, which, however, requires a complicated handling. In particular, this device also requires a two-hand operation.
