Description

The invention relates to a container for in particular liquid, pasty or powdery products, in particular creams, lotions, ointments or powders.

The invention is described using the example of a container in the form of a crucible, d. H. a generally flat, preferably cylindrical and preferably relatively massive vessel. However, this is not a limitation; Of course, the invention can also be used for containers with other shapes.

Crucibles for the products mentioned are often closed with a lid, in particular a screw cap.

To a crucible a high-quality appearance and an equally high-quality appearance during its handling - d. H. To give a high-quality "look and feel" - the crucible is preferably made thick-walled. As a result, the production of the crucible is relatively expensive, since a relatively large amount of material has to be used for the thick-walled design. Furthermore, the crucible is preferably made of glass or plastic, in particular a production of glass - in contrast to a production of plastic - can not be done in economic injection molding.

This also increases the overall cost to the consumer of the product since the cost of producing the crucible must be co-financed by the selling price of the product.

The invention is therefore based on the object to provide a container for particular liquid, pasty or powdery products with low overall costs for the consumer of the product.

This problem is solved by a container according to claim 1 and by an inner container according to claim 10 for use in the container according to claim 1. Advantageous developments of the invention are contained in the subclaims.

The invention is based on the idea of creating a refillable and thus reusable crucible. In a refill solution, the cost of producing the relatively expensive crucible for the consumer is only reflected once, while the product itself can be offered as a refill pack in a simpler designed and thus much cheaper to manufacture package.

To implement this concept of the invention, a container is proposed for in particular liquid, pasty or powdery products with an inner container for directly receiving the product and an outer container, wherein the inner container is receivable in the outer container and detachably connectable with this. In this case, the inner container has a first fastening element and the outer container has a second fastening element which can be brought into positive engagement for producing the releasable connection and disengaged to release the detachable connection. Here, the engagement and disengagement bring the first fastener and the second fastener by the user of the container with manual force and without tools can be made.

Thus, the container having an outer container and an inner container filled with the product can be offered for sale, and after the consumption of the product, the user can easily remove the empty inner container, purchase a new inner container filled with the product as a refill pack, and so on simply insert into the outer container.

The fact that when refilling only the simple and inexpensive to produce and consisting of relatively little material inner container must be exchanged and disposed of, the total costs incurred in the use of the container and the resulting amount of waste are reduced.

Preferably, both the inner and the outer container each have a substantially cylindrical shape, and the inner container is accommodated concentrically in the outer container.

Due to the positive connection of inner and outer container accidental dropping out of the inner container with the product from the outer container is prevented. Through this connection, the user is also given the impression of always having a "one-piece" product container with the usual, high-quality "look and feel" available.

In addition to the positive connection of the inner and outer containers, these can preferably also be non-positively connected, in particular by friction and / or clamping forces.

Preferably, the inner container can also have a plurality of first fastening elements and the outer container can have a plurality of second fastening elements, with a first and a second fastening element respectively engaged and disengaged can be brought. Preferably, the engagement or disengagement of all the first and second fastening elements takes place essentially simultaneously.

In a preferred embodiment of the invention, an edge of the inner container, preferably axially and / or radially beyond an edge of the outer container, when the inner container is received in the outer container, so that the protruding edge of the inner container for the user a gripping surface for gripping the inner container forms.

As a result, the engagement and disengagement of the first and the second fastener and thus the replacement of the inner container by the user with manual force is facilitated.

In a further preferred embodiment of the invention, the first fastening element and the second fastening element form a plug connection. This allows a particularly easy and fast connection of the inner and the outer container. The positive connection between the inner and the outer container acts preferably in the circumferential direction of the two containers, whereby unintentional rotation of the two containers is prevented from each other. In this way, a certain rotational position of the inner container relative to the outer container can be ensured, preferably in order to achieve an optical match between a label of the inner container and a label of the (preferably transparent or partially transparent) outer container.

In a further preferred embodiment of the invention, the first fastening element and the second fastening element form a bayonet connection. The positive connection between the inner and the outer container acts preferably both in the circumferential direction of the two containers and in the axial direction of the two containers, whereby both an unintentional rotation of the two containers against each other with the advantages described above as well as falling out of the inner container of the Outer container is prevented.

In a preferred variant of this embodiment, the bayonet connection can be closed and opened in each case by a combination of a translational movement of the inner container relative to the outer container and a rotational movement of the inner container relative to the outer container.

In a further preferred variant of this embodiment, the bayonet connection has a pin on the outer wall of the inner container and a curved groove in a wall of the outer container. By this arrangement of the elements of the bayonet connection must - in contrast to the reverse arrangement - the wall of the inner container, which is preferably relatively thin, so that the inner container is inexpensive to produce and thus occupies the inner container between the outer container and the product only little space, not through the groove of the bayonet connection weakened or even broken.

In a further preferred embodiment of the invention, the container further comprises a lid which completely encloses the inner container together with the outer container when the inner container is received in the outer container, wherein the outer container has a, in particular cylindrical, cover connecting portion for connection with the lid and the lid having a, in particular cylindrical, outer container connecting portion for connection to the outer container and wherein the second fastening element is arranged in the lid connecting portion.

Due to the arrangement of the second fastening element in the cover connection section of the outer container, the remaining, preferably thick-walled, section of the outer container need not be changed by the second fastening element. The aesthetics of the outer container, which contributes significantly to the high-quality appearance of the entire container, thus retained.

In a preferred variant of this embodiment, the lid connecting portion of the outer container has a substantially cylindrical portion and an external thread and the outer container connecting portion of the lid has a substantially cylindrical portion and an internal thread, wherein the external thread and the internal thread for screwing the lid on the outer container engaged can be, and the second fastening element is disposed in the cylindrical portion of the cover connecting portion of the outer container.

By means of this arrangement of the second fastening element, both the cylindrical portion and the internal thread of the outer container connection portion of the lid can rotate undisturbed when the lid is screwed onto the outer container. The screwing the lid on the outer container is thus not affected.

In a further preferred variant of this embodiment is the first fastener radially outwardly beyond the cylindrical portion of the lid connecting portion of the outer container when the inner container is received in the outer container.

This arrangement of the first fastening element has the same effect as the arrangement of the second fastening element in the last-described variant.

Further advantageous embodiments of the invention are illustrated in the accompanying drawings in conjunction with the following description. Showing:

1 a first embodiment of a container according to the invention in a semi-transparent, perspective view;

2 : A second embodiment of a container according to the invention in a semi-transparent, perspective view.

The terms "top" and "bottom" in the following description refer to the usual orientation of the container when, for example, it stands on a surface so that the product can be removed from above.

The two embodiments common crucible 1 has an outer container 2 and an inner container 3 on, which in a corresponding, downwardly closed cavity of the outer container 2 is included.

The outer container 2 and the inner container 3 have substantially each a cylindrical shape, but may also have other shapes. The cavity in the outer container 2 and thus the inner container 3 are preferably concentric with the cylindrical shape of the outer container 2 arranged.

Preferably, the outer container 2 made of plastic or glass and the inner container 3 made of plastic. However, other combinations of materials may be used.

The outer container 2 has in its lower region preferably a thick-walled section 5 on, where "thick-walled" in the present case means that the wall thickness of the cylindrical portion 5 at least 5%, preferably at least 10% and most preferably about 14% of the outer diameter of the outer container 2 is.

In its upper area, the outer container 2 a lid attachment portion 6 with a cylindrical section 6a with a much smaller wall thickness than that of the thick-walled section 5 on. On the outer side of the cylindrical section 6a is circumferentially made of individual sections existing external thread 7 arranged on a (not shown) cover with a corresponding internal thread can be screwed to close the container.

The inner container 3 has at its upper edge over the remaining inner container 3 radially outwardly projecting ring 4 on, which serves the user as a grip surface to the inner container 3 on the ring 4 to grab and insert it from above into the cavity of the outer container 2 introduce.

The ring 4 is radially above the remaining inner container 3 just so far over that it is radially outward with the cylindrical section 6a concludes. In this way, the rotational movement of the lid when screwing the lid on the external thread 7 not disabled.

In the embodiment according to 1 has the outer container 2 in the cylindrical section 6a the lid attachment portion 6 a semicircular recess 8th on which extends from the top of the cylindrical section 6a extends down and which as a second fastening element for fixing the inner container 3 serves.

Accordingly, the inner container 3 at the bottom of the protruding ring 4 a downwardly extending semicircular wall thickening 9 as a first fastener, which in their dimensions of the recess 8th corresponds, so the wall thickening 9 during insertion of the inner container 3 in the outer container 2 in the recess 8th positively engages.

The recess 8th and the wall thickening 9 thus form a connector, which the inner container 3 at a rotation within the outer container 2 prevents.

Both the recess 8th as well as the wall thickening 9 extend radially only in the region of the cylindrical portion 6a the lid attachment portion 6 and thus do not hinder the rotational movement of the lid when screwing the lid on the external thread 7 the lid attachment portion 6 ,

In the embodiment according to 2 has the outer container 2 in the wall of the cylindrical section 6a the lid attachment portion 6 a curved groove 10 on, which as a second fastening element for fastening the inner container 3 serves. The groove 10 extends, beginning at its open end at the top of the cylindrical section 6a , initially axially down. After an axial extension in a first section 10a down over about half the height of the cylindrical section 6a has the groove 10 a curvature of 90 degrees and runs in a second section 10b whose length approximately corresponds to that of the first section, further in the circumferential direction of the cylindrical section 6a in its wall. The closed end of the groove 10 lies in its second section 10b and has a semi-circular end. The width of the groove 10 is essentially constant. The groove 10 is only at its open end in the first section 10a slightly wider and just before its closed end in the second section 10b a little narrower.

The inner container 3 has in its upper region a radially outwardly extending, cylindrical pin 11 as a first fastening element whose diameter is slightly smaller than the width of the groove 10 ,

When inserting the inner container 3 in the outer container 2 the pin engages 11 initially axially in the upper end of the groove 10 a positive fit and goes through the first section 10a the groove 10 , Then the user needs a rotation of the inner container 3 relative to the outer container 2 perform, causing the pin 11 the second section 10b the groove 10 goes through to the end. Just before the closed end of the groove 10 the user has to spend a little bit more force around the location of reduced width of the groove 10 overcome, causing the pin 11 at the closed end of the groove 10 locks.

The groove 10 and the pin 11 thus form a bayonet connection, which the inner container 3 both in rotation and in axial movement within the outer container 2 prevents.

The release of the bayonet connection takes place in the opposite way to the procedure described above, wherein the user again first the resistance at the point of reduced width at the closed end of the groove 10 must overcome, so that the pin 11 from the closed end of the groove 10 disengages.

Of course, the groove 10 and the pin 11 also have other coordinated courses or forms to form a bayonet joint together.

Both the groove 10 as well as the pin 11 extend radially in the cylindrical portion 6a and thus do not hinder the rotational movement of the lid when screwing the lid on the external thread 7 the lid attachment portion 6 ,
