Description

Tin box closure One already knows bottle closures, consisting made of a disc made of metal with the bottle neck rim bead turned downwards enclosing lobes which, due to their elasticity, are normal against the bottle neck are pressed, but by a pressure on a bent part of the disc can be spread out so that the closure can be removed. These In addition to bottles, the arrangement can also be used for circular boxes, but not for square or oval boxes.

It has also been suggested to have square containers with a through Pressure releasable closure to be provided. But the lid was set up so that to open the closure one presses on the one engaging in the container had to exercise side edge of the lid to bring it out of engagement with the container.

According to the invention, the arrangement is now made so that the on known sheet metal box closure with a bent part on the lid disc, on the one to spread apart the corners surrounding the box Can exert pressure, is designed such that it is also suitable for sheet metal boxes of rectangular or oval shape is applicable. To that end, it's down curved edge of the lid on the long edges with two opposite one another provided with narrow lobes that fit into corresponding indentations in the box itself engage and disengage by pressing on the domed lid of the box can be brought with those indentations.

In the drawing, the invention is illustrated, for example, namely Fig. 1 shows a top view and Fig. 2 shows a vertical section the line II-II in Fig. i.

Fig.3 shows a box from the front and Fig.4 shows a modified one Embodiment in side view.

Fig. 5 is a section along the line V-V of Fig. 4, and Fig. 6 is a longitudinal section through the box shown in Figures 4 and 5.

The box i itself has exactly in the middle -section plane II-II, which cuts the long sides of the box vertically, a few indentations a, and the cover 3 has two short, inwardly facing indentations corresponding to these indentations Tip 4. The lid has a round, upturned curvature 5 and one oval depressed furrow 6.

If the lid is to be removed or put on, one presses on its arched part 5, and thereby the two lugs 4 are bent outwards, while the remaining part of the downwardly taught edges of the lid is not significantly influenced by this pressure. The lid can now be removed and put back on. After putting the lid on, all you need to do is press the middle of the long sides of the lid to remove the tabs q. to force into the bends a, whereby at the same time the curved part 5 is lifted into its normal position. A very similar arrangement can be applied to boxes of oval or other elongated or possibly square shape.

A suitable closure can be used for boxes with sliding lids be used when the downwardly curved edge of the box lid is along a Side of the box is removed. Pressing the middle of the lid spreads the Lugs without disengaging them completely; and the box lid can then be pushed to the side.

A modified embodiment is shown in Figures 4 to 6, which show a pill box in the form of a completely closed box i, only a small hole 7 is present in the ceiling 9; over that solid ceiling sits an outer sliding cover that can be moved so far that the hole 7 in the top of the box is covered.

This inner box cover 9 does not need to be present, but can be omitted and forms in other applications of the box not part of the innovation. The downward curved frame of the outer lid is along one narrow side of the box, and the lid can be at this point instead of the frame, it is provided with a narrow edge 8 that is slightly bent downwards that just grips around the top edge of the box when the lid is closed, but who lets go of his grip when you press the center of the domed lid.

On the two long sides of the lid is the downward curved frame provided with lobes, which are bent here under the bottom of the box and either press it straight or interact with depressions in it.

When the box is to be opened, the center of the lid becomes pressed down, which stops the pressure of the tabs4 against the box. Simultaneously the edge 8 gives up its grip on the box, and the lid can now give way to the right in Figures 4 and 6. When the box opening 7 is closed again, you press lightly on the tabs 4 supporting edges of the lid bent at the bottom. The curvature of the lid springs back, and. the box is then closed.

Claims (1)

PATENT CLAIMS: i. Tin box closure with a bent out Part on the lid disc that you can apply pressure to in order to create a To cause spreading apart the tabs surrounding the box, so that the closure can be removed, characterized in that this closure also made applicable for sheet metal boxes of rectangular or oval shape is that the downwardly bent edge of the lid (3) on the long edges two opposite tip (4) carries, which in corresponding indentations (z) the box itself and engaging by pressing on the domed lid the box can be disengaged from the indentations. a. Embodiment according to claim i, characterized in that the cover is designed as a sliding cover is whose frame-like edge bent downwards on two opposite sides Has side tabs (4) that grip under the bottom of the box while on one of the other two sides of the cover instead of the longitudinal edge of the rectangular one Box lid removed, downwardly curved edge part, only slightly The narrow edge strip (8), which is curved at the bottom and which turns around when the lid is closed the box edge engages in such a way that a pressure is exerted on the curvature of the box lid not only causes the pressure of the tabs (4) against the box to cease, but also brings the edge part (8), which is slightly bent downwards, to the edge of the box let go, so that the cover can be moved in the longitudinal direction.
