Description

The invention relates to a device according to the Preamble of claim 1.

Devices for mixing two components, consisting of a vessel with a connecting element and one on the Vessel-mountable lid elements are available in a wide variety Embodiments known. For example, there are essays that about a screwing movement of a screw element on a threaded neck of a vessel are able to cut through the foil used.

In a device known from DE-A-39 24 152 a cover element in the form of a cap with one in the Provide a tooth protruding into the thread neck of a container, a film in the screw movement of the cap Cuts out the threaded neck. Separates the film two different ones Components, for example two liquids or a liquid and a powdery substance after cutting the film and shaking the Container a mixture of the two components.

DE-A-42 19 063 describes a mixing device two components, consisting of a vessel open at the top with a screw thread as a connecting element and a Known screw-on lid element known which in the area of the upper edge of the open vessel Cutting mandrel is provided and in the screw element detachable depot vessel is used. With the cutting mandrel of the open vessel can be a film of the depot vessel be severed.

From DE-A-2432290 a device according to the preamble of claim 1 is known.
This device consists of a vessel with a connecting element and a lid element that can be placed on the vessel, a detachable depot vessel with a foil arranged on the vessel side, a recess in the lid element, and a cutting mandrel on the foil. The lower inside diameter of the depot vessel is larger than twice the distance between the vertical central axis of the depot vessel and the cutting mandrel, so that the cutting mandrel can cut through the film.

The use of such devices for Example of separate storage of Liquid components that appear just before their use should be mixed. A mixture of the Individual components are then only for a certain period of time processable, for example the components Permanent wave solution and ester for a hair treatment. Such Devices can also be useful for separate Storage of a dusty product and one Liquid can be used. As a result of the dissolution of the dusty product, for example a natural product Hair dye powder, in the liquid is one No dust development to the detriment of a user Given time.

A disadvantage of the known devices is that they are either relatively cumbersome to use or for an at least partial reuse is not suitable are. Or they're relatively smaller for use, interchangeable depot tubes not suitable.

The invention has for its object a device for mixing two components, according to the preamble of To create claim 1, the above disadvantages has, and a much easier replacement of the Depot vessel allowed.

The task is solved according to the characteristic part of the Claim 1. Then the cutting mandrel is on the edge of Recess provided and rigid with the cover element connected, and the depot is from above into the Recess and can be placed on the cutting mandrel.

In the solution according to the invention, the depot vessel is placed in the recess of the lid element after the lid element has been screwed onto the vessel.
When the depot vessel is placed on the lid element, the cutting mandrel arranged on the lid element pierces the film of the depot vessel. As a result, a product component contained in the depot vessel reaches the underlying vessel to a second product component present there. The entire device for mixing the product components is hermetically sealed. The mixing of the two product components can be improved by shaking the device.

The device according to the invention is relatively simple in construction and therefore inexpensive to manufacture. The vessel and the screw element can be manufactured by injection molding, as can the depot vessel. The film for the depot vessel is connected to the depot vessel, for example, by heat sealing. The container and the lid element can be reused after cleaning using a new depot container. A restoration of the functionality of the device is easily possible by a user insofar as, instead of an empty depot vessel, only a new, filled depot vessel has to be inserted into the screw element.
The diameter of the recess can also be relatively small, so that small depot vessels can also be used.

Further advantageous embodiments of the invention Device are described in claims 2 to 9.

The cutting mandrel extends around the recess on something more than a three-quarter circle (claim 2), then prevents the film from being completely separated from the depot container and falls into the vessel below, where the two product components mix.

The foil is a plastic-coated aluminum foil (Claim 3), the two components of one Foil separated due to the aluminum layer good barrier properties regarding product diffusion has, and because of their plastic coating (for example the same plastic as that Depot vessel) are sealed on the edge of the depot vessel can.

A particularly simple handling of the invention Device is reached when according to claim 4, the depot can be positively clamped in the cover element. An emptied depot container is pulled out of the lid element, and a new depot is placed in the lid element put in.

If a seal is provided on the edge of the vessel (claim 5), the edge when screwing on the cover element of the vessel against the seal and thus the Hermetically sealed interior of the vessel. Also at Shaking or turning the screwed device can no liquid should come out of the device.

The depot vessel can be manufactured particularly precisely if it is according to claim 6 consists of injection molded plastic.

Are gripping surfaces provided on the depot vessel (claim 7), so are placing the depot container on the lid element and simplified rotation of the depot vessel.

Analogous to claim 8 is the level in which the recess is inclined towards the bottom surface of the vessel, so is the distribution behavior from the depot vessel into the vessel improved.

If the cutting edge of the cutting mandrel lies in the area of the Snap area of the depot vessel (claim 9), so it is possible, this already when the depot vessel snaps into place open using the cutting edge.

The invention is described in more detail below with reference to figures which illustrate exemplary embodiments. It shows:

The device 1 according to the invention consists of an open vessel 2, a depot vessel 3 and a cover element 4 (FIG. 1). A cutting mandrel 6 is arranged on the upper region 5 of the cover element 4. The vessel 2 is provided with an external thread 7 at its upper region. The depot 3 is closed with a film 8. In the depot vessel 3 there is a powder component 9. A mixture of the powder component 9 with the liquid component 10 in the vessel 2 results in a ready-to-use solution.
In order to introduce the powdery component 9 into the liquid component 10, the depot vessel 3 is inserted into the snap-in area 11. The film 8 of the depot vessel 3 snaps all around underneath the beveled locking ring 12 of the cover element 4. The depot vessel 3 is rotated while applying pressure with the aid of the gripping surface 13, and the cutting mandrel 6 cuts through the film 8 in a circular manner and the powdery component 9 falls through the recess 14 of the cover element 4 into the liquid component 10. The cutting mandrel 6 extends over more than a three-quarter circle around the recess 14 (FIG. 3).

After the powdery component 9 to the liquid Component 10 has arrived, the device can better mixing of the components. Is located between the cover element 4 and the open vessel 2 an annular circumferential seal 15 (FIG 1), in order to reliably prevent liquid leakage there.

In another embodiment (Figure 2) is the Level in which the recess 14 is located opposite the floor surface 16 of the open vessel 2 inclined. This allows the Component 9 better after the cutting process in the direction of Component 10 are emptied.
