Definitions

  • the invention relates to a container with the features of the introductory Part of claim 1.
  • Such containers are used for example in the cosmetics industry, if two substances are used together just before use are to be mixed.
  • a two-chamber container with the characteristics of the introductory part of claim 1 is known from FR 2599006 A.
  • the top of the container is opened by turning the cap Container, which is screwed onto the lower part, rotated and so on adjusted in the axial direction relative to the lower part of the container, so that by the provided on the cap, in the Interior of the top protruding device in the bottom of the top one Connection opening between the two receiving spaces of the known Container is manufactured.
  • the invention has for its object a container with two Reception rooms for liquid to be stored separately from each other Media to be mixed before use is available to provide the simplest possible structure, the consists of as few individual parts as possible and that after mixing the liquid media allows the batch to be easily applied there, where it is needed. Doing so is an unintended Moving the cap and thus an early manufacture of the Connection opening between the recording rooms can be prevented.
  • this consists of a bottle-shaped lower part 2, in which the first receiving space 3 is accommodated, and one on the lower part 2 attached upper part 4, in which the second Recording room 5 is housed for a liquid medium.
  • the interior of the bottle-shaped lower part 2 serves as the first receiving space 3 for receiving a first liquid medium 6.
  • the Recording space 5 in the upper part 4 receives the second liquid medium 7.
  • the screw cap 10 On the upper part 4 containing the second receiving space 5 is one Screw cap 10 on a hollow, tubular nozzle 11 with the help screwed on a thread 12.
  • the screw cap 10 In the area of its pouring opening 13 is the screw cap 10, for example, by a detachable, preferably with the screw cap 10 one-piece closure part 14 locked.
  • the nozzle 11, on which the cap 10 is screwed is, with its lower end 15 in the neck 16 on the upper end wall 17 of the bottle-shaped lower part 2 and closed there by a membrane 20 so that the receiving space 5 in the upper part 4 of the container 1 from the receiving space 3 in the lower part 2 of the Container 1 is separated, and the liquid media 7 and 6 can't mix with each other.
  • a bell-shaped wall part 22 protrudes from the nozzle 11, its free edge 23, for example by a snap connection 24 with the wall 25 of the lower part 2 in the area between the Side wall 25 and the upper end wall 17 provided inwards jumping shoulder 26 is connected. So the lower part 2 is with connected to the upper part 4 of the container 1.
  • the snap connection 24 between the upper part 4 and the lower part 2 of the container 1 includes one above the shoulder 26 to the outside projecting ring rib on the wall 25 of the lower part 2 and in Area of the free edge of the bell-shaped wall part 22 of the Upper part 4, an inwardly facing ring rib.
  • each other connected lower part 2 and upper part 4 is the free edge of the Wall portion 22 on the inwardly facing wall area of the shoulder 26 on and the rib on the wall part 22 engages under the rib on the Wall 25 of the lower part 2. So is a simple snap connection 24 given.
  • the closure cap 10 has an inwardly projecting, hollow, cylindrical projection 34, which is within the nozzle 11 of the upper part 4 is received and preferably with its outer surface abuts the inner surface of the nozzle 11.
  • the approach 34 is in the longitudinal direction interrupted at least once, e.g. by at least one Longitudinal slot.
  • the free, downward-facing edge of shoulder 34 is designed as a cutting edge 36, which is shown in FIG Position of the container 1 in which the two receiving spaces 3 and 5 not yet connected to each other, the the recording rooms 3 and 5 separating membrane 20 is assigned.
  • An unintentional moving the cap 10 down, for example by a screw movement of the cap 10, is by the between its lower edge 30 and the shoulder 31 in the wall 22 the upper part 4 provided guarantee ring 32 prevented.
  • To remove the membrane 20 by the cutting edge 36 on To facilitate approach 34 can be on the edge of the membrane 20, that is, where the cutting edge 36 attacks, a line of weakness (material thinning) be provided.
  • the cap 10 can the mixed medium from the now together connected first and second receiving spaces 3 and 5 poured out or by elastic deformation of the lower part 2 of the container 1 be pushed out.
  • FIGS. 7 and 8 largely corresponds the embodiment shown in Figs. 1 to 6 with the Difference that the two recording rooms 3 and 5 are not by one Membrane, but by a closure element 35 in the manner of a stopper are separated from each other.
  • the closure element 35 is in the lower end of the nozzle 11 used in the upper part 4 and is by an outer rib 56 which over the upward end 37 of the Opening limiting wall 38 engages, held.
  • an outer rib 56 can also be provided with several retaining projections his.
  • the closure element 35 can also be a full plug be made of (rubber) elastic material.
  • a (hollow) stamp 40 arranged in the shown Embodiment two (or more) in cross section has arcuate wall parts 41, the free ends 42 in the 7 shown position (separate receiving spaces 3rd and 5) on the surface of the closure element facing the receiving space 5 35 abut or are arranged just above this.
  • the cap 10 can be moved down, the closure element 35, as shown in Fig. 8, from the lower opening of the second receiving space 5 limiting nozzle 11 is pushed out and the liquid contained in the receiving rooms 3 and 5 Can mix media with each other.
  • the further handling is similar to that of FIGS. 1 to 6, it should be pointed out that the stamp 40 on the cap 10, the closure element 35 is assigned, the pouring is not hindered because between through its wall parts 41 through slots 43 are provided.
  • a support e.g. a ring is provided which from the inside on the inner surface of the ring wall pointing upwards of the closure element 35 abuts. This will prevent the rib 56 undesirably released from the end 37.
  • FIGS. 9 to 14 corresponds to the differences described in 7 and 8 embodiment shown.
  • Upper part 4 is at the lower end of the second receiving space 5 to the side bounding wall of the nozzle 11 .
  • Internal thread-bearing extension 50 is provided.
  • the extension 50 can have an external thread on the neck 16 of the bottle-shaped lower part 2 can be screwed.
  • the outer wall 22 of the upper part 4 is seated with its free edge in the edge region of the upper wall 17 of the lower part on and in an annular step molded there.
  • the inwardly facing, lower edge of the nozzle 11 parallel to the An internally threaded extension 50 of the same has a ring flange 51 provided which engages in the neck 16 of the lower part 2 when the Lower part 2 is connected to the upper part 4, as shown in FIGS. 13 and 12 show.
  • the Cap 10 are moved only after the guarantee ring 32nd has been removed.
  • FIGS. 9 to 14 has the advantage (see Figs. 9 and 10) that the lower part 2 through a over his neck 16 screwed cap is still closed when the top 4 is not attached.
  • This allows, for example, in a shop, bottom parts 2 and filled with liquid media
  • upper parts filled with the corresponding liquid medium 4 and lower parts 2 are selected and the two parts of the container 1 after removing the screw cap from the lower part 2 by screwing on of the upper part 4 are connected to each other.
  • FIGS. 9 to 14 can as a finished unit, namely as a container 1 with each other connected lower part 2 and upper part 4 are available for purchase.
  • Bottom part 2 top part 4
  • FIG. 15 An embodiment of how this can look in detail is shown in 15 to 18.
  • a container is shown, the is constructed similarly to the container shown in FIGS. 7 and 8. In this respect, it is therefore possible to refer to the description of FIGS. 7 and 8 shown embodiments are referenced.
