Description

Closure arrangement for crucibles with oblique crucible shoulder

The present invention relates to a crucible, in particular suitable for cosmetic products, with a crucible bottom part, in which the receiving space for a product is formed, a lid which can be fastened and detached on the crucible bottom part.

Generic crucibles are known from DE 202010009078 U. Crucibles of this type are used in great variety, especially for cosmetic products use. In order to obtain a visually appealing appearance, the contours of the crucible bottom part pass without offset into the crucible lid. For this purpose, the crucible bases have a cup-shaped body, which is adjoined by a cylindrical collar (crucible neck) which is reduced in its circumference relative to the body. The connection between cup-shaped body and cylindrical collar, the crucible shoulder, represents a paragraph. The cylindrical collar serves to receive the lid whose outer circumference corresponds to the circumference of the cup-shaped body. The crucible shoulder runs in known crucibles parallel to the footprint of the cup-shaped body or perpendiculular to the crucible main axis. In cylindrical or rotationally asymmetric crucibles, the crucible main axis is equal to the axis of symmetry.

Lid for generic crucibles have a cylindrical collar on the circumference is greater than the outer diameter of the crucible neck, so that the lid can be slipped over the crucible neck. Crucible bottom and lid are separated in the crucibles of the prior art by a visible, running parallel to the footprint 'line'.

On the outside of the crucible neck there are threaded closure parts that can interact with complementary threads located on the inside of the cylindrical collar of the cover, thus leading to lidded crucibles for a fixed but releasable connection.

The threads are symmetrical in height and distance on the cylindrical collar of the lid and arranged on the crucible neck. Only by a symmetrical arrangement, a simple screwing the lid can be achieved without previously accurate positioning of the threads of the lid and crucible neck to each other suc- must be. The thread automatically engages as the lid rotates, resulting in a secure closure of the crucible.

Depending on the requirements, the threads can be configured between multiple circulations up to very short sections, so-called catch hooks or closure elements (DE 60206956 B). State of the art, it is also the threaded sections with stop stages and .Klickstufen 'or bevels (chamfers, inlet slopes) to be provided to prevent over-rotation or to allow better mesh.

Object of the present invention is to provide crucibles available, the crucible shoulder is not parallel to the footprint of the cup-shaped body or not perpendicular to the crucible main axis, wherein between outer surface of the crucible body and outer surface of the lid in the closed state no paragraph but a visible, to

Contact area not parallel, dividing line is created.

This object is achieved in that the crucible neck has at least two closure elements, which are arranged in parallel, ie with the same distance to the crucible shoulder, with the result that the closure elements have a different distance to the edge of the crucible neck, as long as the edge of Crucible neck does not run parallel to the crucible shoulder.

Crucibles according to the invention have between the outer surface of the crucible body and the outer surface of the lid in the closed state only one seam but no shoulder, wherein a visible, not parallel to the contact surface, dividing line is formed. The body and lid have the same circumference or diameter.

The lid of a crucible according to the invention has the same number of complementary closure elements, which are arranged in parallel, ie at the same distance to the edge of the lid, which is meant with lid edge that portion of the lid, which comes to lie in the closed state of the crucible on the crucible shoulder and concludes with this.

Only with this arrangement of the closure elements is ensured that the positioned on the crucible neck and the crucible lid closure elements can interlock. If the closure elements of the crucible neck were arranged parallel to the edge region (crucible opening) of the crucible neck and complementarily in the cover with different arranged chem distance to the lid edge, so closure positions of the lid would be given in which the lid edge is not flush with the crucible shoulder.

The pitch of the threaded portions, based on the crucible main axis according to the invention is equal to or greater than the angle forms the crucible shoulder with the crucible main axis. The angle between crucible shoulder and crucible main axis is determined from the highest and lowest point of the crucible shoulder relative to the crucible main axis.

In general, the closure elements thread segments, so short threaded sections which extend only over a fraction of the circumference of Tiegelhals or cover. For the purposes of the invention is to be understood by closure element and the equivalent acting combination of grooves and cams, as in bayonet / Renkverbindung.

The higher the number of closure elements that are arranged over the circumference, the less freedom there is in putting the lid. In the case of two closure elements, the span width of the attachment angle is almost 180 ° -x °, where x is the circumference occupied by the closure elements. With three threaded sections only approx. 120 ° -x °.

According to the invention, it is preferable to arrange 2 to 6 closure elements evenly distributed over the circumference.

Particularly preferred is the arrangement of three closure elements over the circumference of the crucible neck, wherein a closure element is arranged in the region of the lowest point of the crucible shoulder.

Certain embodiments of the closure arrangements on which the invention is based are described below by way of example and with reference to the enclosed figures.

The following reference numbers are used:

1 crucible bottom

2 crucible lids

3 cup-shaped body

4 crucible neck 5 footprint

6 crucible main axis

7 crucible shoulder

8 closure elements of the crucible neck

9 lid margin

10 closure elements of the lid

10.1 stop level

1 1 lid margin

α Angle of the crucible neck to the crucible main axis

ß angle of the crucible bottom to the crucible main axis

Figure 1 shows a crucible according to the invention in side view, comprising a crucible bottom part (1) and a crucible lid (2). The crucible base (1) has a cup-shaped body (3), which carries on its open side the crucible neck (4). The connection between crucible neck and cup-shaped body is made by the crucible shoulder (7). In the illustrated embodiment, the crucible main axis (6) is perpendicular to the contact surface (5). The crucible shoulder (7) is set at an angle alpha (a) with respect to the crucible main axis (6). The crucible neck (4) has closure elements (8) which are arranged parallel to the crucible shoulder. The crucible lid (2) also carries on its inside closure elements (10), which are arranged parallel to the lid edge (1 1). The closure elements (10) carry a stop step (10.1), which prevent over-rotation of the lid.

FIG. 2 shows a plan view of a crucible according to the invention. The crucible has in each case three closure elements (8, 10) on the crucible neck (4) and on the crucible lid (3).

Figure 3 shows a crucible according to the invention in the side view with attached lid, comprising a crucible bottom part (1) and a crucible lid (2). The crucible base (1) has a cup-shaped body (3), which carries on its open side the crucible neck (4). The connection between crucible neck and cup-shaped body is made by the crucible shoulder (7). In the illustrated embodiment, the crucible main axis (6) is not perpendicular to the contact surface (5) (ß 90 °). The crucible shoulder (7) is set at an angle alpha (a) with respect to the crucible main axis (6). The crucible neck (4) has closure elements (8) which are arranged parallel to the crucible shoulder. The crucible lid (2) also carries on its inside closure elements (10), which are arranged parallel to the lid edge (1 1). The closure elements (10) carry a stop step (10.1), which is an over-rotation of the D e c k e l s v e r h e n d e r n.
