Description

The invention relates to empty containers for holding pasty or powdery substances, in particular pharmaceutical and cosmetic substances, cleaning and polishing agents or other cleaning and care agents, with an inner lid having a handle which can be inserted into the cylindrical container and axially in it is displaceable and rotatable

For the packaging of shoe polish or other pasier-shaped care products, cans are known which with a piston-like design, in the cylindrical

ίο Can insertable lids are provided, the <in his The underside has a flexible, porous pad with which the paste is removed from the jar in portions and can be applied to the treatment area. The lid is also used here as a removal and applicator for the container contents formed since the lid by interlocking projections and wells is rotatably held in the container, rotating the lid is for portion-wise The paste cannot be absorbed.

Furthermore, containers are known in which the lid by means of a screw cap or by clamping is set on the container. To remove the contents of the container, there is a Container insertable separate removal device is provided, which consists of a handle attached sponges or the like.

From DE-GM 19 00 560 a container of the type mentioned is bek innt, the one with a handle has provided inner lid, which can be introduced into the cylindrical container, in this axially is displaceable and rotatable. The inner lid here only forms an aroma-tight inner seal, which is provided in addition to the actual container lid. The function of a removal and In contrast, the inner lid does not have an application device for the container contents.

Finally, from FR-PS 13 98 903 is a plastic container known, the lid by means of a twist clamp fastener at the top of the cylindrical

• w container can be locked. For this purpose are on The upper edge of the container and the inner circumference of the lid clamping members are formed, which are made in the circumferential direction There are wedge-shaped rising V-ledges. Again, the lid is not used as a removal and Order device for the portion-wise removal of the Container contents «. as well as for spreading the removed Container contents formed The lid is also cannot be introduced into the cylindrical container.

The object of the invention is to form a container dei eingangsgenannie η kind as simple as possible Weiseso that can be formed with the same time as a withdrawal and Auftragsgeräl inside lid of the Behalterinhalt easily remove portions and • at the same time, the container seal reliable.

This object is achieved according to the invention in that the at the same time as a removal and application device for the portion-wise collection of the contents of the container formed Inner lid inside the container in different insertion handles by means of a twist clamp fastener is lockable. from on the inner wall of the container and on the outer circumference of the Interior ceiling hv arranged at circumferential intervals, clamping elements interacting in pairs be * stands, which in Üirlfarigsrechturig dnc such small

Have dimension and are arranged in such a large Umfängsabsland that the in the Container inserted at any depth, at least over an angle of rotation of about 30 °, preferably

from about 70 to 110 ", without jamming in the container is rotatable.

In this embodiment of the container, the inner lid that can be inserted into the container accordingly forms at the same time a removal and application device with which the contents of the container can be completely emptied the container can be removed in portions it is possible, depending on the filling level, to move the inner lid more or less deep and when the container is almost empty up to Introduce the bottom of the same without jamming and turn it in by a certain angle to lock each insertion depth in the container reliably. The lock can be turned in Solve opposite direction without difficulty. When the lock is released, the inner lid can be placed in the container Rotate freely to and fro to allow the powdery or pasty contents of the container to pass through the lid cushions arranged on the underside or the like. Both the insertion of the piston-like inner cover into the container as well as turning the inserted inner lid to accommodate the container contents as well finally also pulling out the inner lid the container can be conveniently in the jam-free Achieve the condition of the inner lid.

To ensure a safe and reliable locking of the inner lid in the container and, at the same time, a sufficient one To maintain the rotational mobility of the inner cover in the unlocked state, it is sufficient if at the Inside wall of the container and on the outer circumference of the lid, three clamping elements each at an angular distance of 120 ° are arranged. The clamping organs preferably consist of arranged on the inner wall of the egg container, radially projecting narrow strips and arranged on the cover circumference, wedge-shaped in the circumferential direction rising wedge projections. To lock the inner cover in each insertion depth / u allow, the axial strips expediently extend approximately over the entire inner height of the Container. The wedge projections on the inner cover advantageously have an axial height. which is considerably smaller than the total height of the Inner lid. The strips preferably consist of narrow, slightly rounded ribs. Because the said Clamping elements, based on the total circumference of the container or the inner lid. are only very narrow, the inner lid can be inserted into the container without this generally being necessary. by relative rotation of the inner lid and container to search for a specific rotational position in which the The inner lid can be inserted into the container without jamming. If, however, the inside cover should be a rotational position can be introduced into the container, in which d «: clamping elements on the container and inner lid are coaxially opposite and therefore collide, only the inner cover or the Container to be rotated through a small angle of no more than about 10 to 20 degrees in order to reach the rotational position / u in which the inner lid can be inserted into the container without jamming leaves. This rotary movement can be promoted by the fact that, according to a further feature of the Invention, the wedge projections an arcuately curved Subchannels reverberate. In this case, the Meeting of the Klemmörgane under the We ^ As a result of the axial insertion movement, there is a slight relative rotation between the inner lid and the container practically automatically enforced without the user having to worry about the type and manufacture of the closure needs to make special thoughts.

The container according to the invention can be due to its two-part design and due to the simple design of the rotary fastener comparatively cheaply made of plastic without it Here the exact fit of the inner lid and the container is important. A seal between the container and lid circumference can be achieved in a simple manner that the arranged on the lid underside resilient support for the removal of the container contents is designed so that it is in the radial direction protrudes slightly over the outer circumference of the inner cover and thus when it is inserted of the inner lid into the container while gently compressing it against the inner wall of the container The said edition can, for. B. od from a foam cushion or a felt disk. Like. exist, which can be glued or welded to the inner lid.

The inner cover itself consists expediently of a cylindrical plastic hollow body whose Height (including the above!) Support at least approximately equal to the depth of the plastic too manufactured cylindrical container and the one serving as a handle at the top is expedient has a broad approach.

In the above drawing is an embodiment of the Invention shown. It shows

1 shows a perspective illustration of the container according to the invention in the closed state;

F 1 g. 2 the container according to FIG. I in perspective Illustration, wherein the inner lid is removed from the container;

F i g. 3 in a partial view or a partial section the container filled with paste and the container filled with it separate inner lid;

4 shows the container according to FIGS. 1 to 3 with the inner lid inserted in a plan view.

The container shown in the drawing is made in two parts from plastic. It consists of one flat, pot-shaped plastic container 10, which has a flange-like reinforcement 11 on its upper edge auth. On the cylindrical inner wall 12 of the container are three at angular intervals of 120 ° narrow, rib-like strips 13 formed, which extend from the bottom 14 of the container to its upper free Extend edge. As the F i g. Figures 2 and 4 show the radially projecting narrow strips in their Rounded outer contour.

The inner lid of the container 10, which serves as a closure lid, is designated by 15. The inner lid serves at the same time as a removal and application device for the paste 16 located in the container (FIG. 3). to this purpose is on the underside of a topfior.nigen, cylindrical plastic hollow body existing inner cover 15 a resilient disk 17 made of FiIz or another resilient and porous material /. B. attached by gluing or welding.

The inner piglet 15 has such an axial Dimension that it can be inserted into the container 10 to a depth in which the support 17 against the container bottom 14?. In this position are the horizontally or slightly inclined Areas 18 of the cover recesses 19 located on the upper side of the inner cover are approximately at the same height with the upper edge 11 of the container. The cover part 20 located between the recesses 19 forms

an approach protruding from the container, which serves as a handle for the inner lid.

The inner cover has three arranged at an angular distance of 120 ° on the cylindrical outer circumference Wedge projections 21, which in the Utti longitudinal direction of the point 22 is wedge-shaped up to a radial Schuller 23 rise and the lower edge 24 of which is curved downward in an arc shape from the point 22 to the shoulder 23 is how this F i g. 2 shows. The wedge projections 21 thus have an approximately triangular shape in plan view Outline shape, the lower triangle side 24 a has an arcuate course.

In Fig. 2 the wedge rise of the projections 21 is shown somewhat exaggerated. The step formed by the shoulder 23 between the cylindrical outer circumference of the inner cover and the apex of the wedge projection is in reality somewhat smaller than shown here. The dimension of the wedge projections 21 ifi Un'ifäfigSfici'iiüfig is so small that between the wedge projections 21 a smooth cylindrical cover peripheral surface remains, the arc angle X is about 90 to 100 ° here. It is therefore possible to insert the inner lid 15 as deeply as desired into the container 10 without, as a rule, first having to search for the rotational position required for the insertion. Like Fi g. 4 shows, after the inner lid has been inserted, it can be locked to the container 10 at any insertion depth by rotating the inner lid in the direction of arrow P. In this case, the wedge projections 21 run onto the strips 13 on the inner wall of the container, thereby wedging the inner cover in the container. By rotating in opposite directions by a relatively small angular amount of z. B. 5 to 20 °, the inner cover can be solved again. If, in an exceptional case, the inner lid 15 is inserted into the container 10 in such a way that the wedge projections 21 abut against the ledge projections 13, a slight rotational movement of the inner lid is sufficient to bring the projections 13 and 21 out of their axially parallel position and thus to insert them without jamming of the inner lid into the container. This rotary movement is promoted by the fact that the wedge projections 21 are curved in a side view on their edge 24 which is vertical to the cylindrical peripheral wall of the inner cover. If the curved surfaces 24 come up against the upper end faces 13 'of the strips 13 during the production of the lid, a slight turning movement of the inner lid is already forced by the low insertion force with which the inner lid is pushed into the container

ίο of the upper ends 13 'of the strips from the edge 24 slide to the side and the innefideckcl in a rotational position is brought in which he is free of small expression in the container can be inserted.

In particular, it can be seen from FIG. 4 that the inner cover inserted into the container can be rotated in the unlocked state by approximately the angle X without the clamping members 13 and 21 coming into contact. This offers the

Paste 16 within the stated amount and twist to cause the paste to adhere to the resilient support 17. The inner lid can then klemmungsfrci again to apply the absorbed paste to a treatment area pulled out of the container.

In order to achieve a seal of the container on the outer circumference of the inner ceiling, it is recommended that the Resilient support 17 to be dimensioned so that it with its peripheral edge 17 '(Fig. 3) slightly over the

JO protruding cylindrical outer wall of the inner lid. When the inner cover 15 is inserted into the container 10, the protruding edge 17 'of the flexible lid support from the annular gap between the edge of the container and the circumference of the lid.

The container can be used to hold various substances that are made up in portions can be removed from the container. It is used in particular to hold pasty or powdery substances, like especially pharmaceuticals. Cosmetics, cleaning and polishing agents or other cleaning and care agents.
