Title:

Bottle with a cap that can be fixed in one end position.

Utility model

The innovation relates to a bottle with a closure cap which has a threaded bushing in a jacket with an internal thread can be screwed onto an external thread of a bottle neck that sits on a bottle holder, the bottle body and the bottle neck is asymmetrical with respect to the external dimensions and a cam is provided on the bottle that is, when the closure cap is screwed on and fixed in an end position against a stop provided on the closure cap is applied.

£ ine asymmetric closure cap must be fixed in a final position, if it is to form in a screwed state with the bottle line. In this final position, a reliable seal must be provided at the same time. In a known (DT-GIv '1 90C 904) bottle with a closure cap of the type mentioned at the beginning, the bottle is dp "crouching in the threaded part

of the external thread of the Piaschenhalses provided and is the stop also designed as a cam and sits in the threaded part of the internal thread. On the other hand, there is also a form-fitting Stop of the thread ends of the internal thread and the external thread possible.

Is the well-known closure in flexible plastics and If fine threads are used, difficulties arise in that when the cam is turned vigorously against the stop the thread ends rise and thus the exact positioning of the cap on the bottle is no longer guaranteed is. When screwing large closure caps onto small-diameter bottle necks, the piae necks are affected A large amount of torque is exerted, which often leads to the neck of the bottle breaking.

The innovation now sees a bottle with a cap from the beginning mentioned type, which is characterized in that the cam is provided on the bottle shoulder and the stop is provided at the lower edge of the threaded bushing of the closure cap, where d? 3 Height of the stop of the lowering of the sealing cap corresponds to one revolution of 360 ° or less.

In the case of a bottle according to the invention, a torque is generated essentially transferred to the bottle shoulder, so that the innovation is particularly useful for large caps and small diameter bottle necks is applicable.

It is conceivable to arrange the cam at a small distance from the bottle neck, so that when the cap is screwed on, the lower one The edge of the threaded bushing protrudes between the cam and the bottle neck, in which case the stop resting on the cam acts as a cam formed is provided laterally on the threaded bushing. It is preferred, however, if the cam is close to the bottle neck and the stop is provided under the Rpnd of the threaded bushing, since with this design the stop is easier can be produced.

In the drawing, the innovation is based on a preferred embodiment exemplified and shows

1 shows an upper part of a bottle with a screwed-on closure cap, partly in section,

FIG. 2 shows a section along line H-II in FIG. 1 through the closure cap,

Fi: .-. 3 shows a section along line IH-III in FIGS. 1 and

4 shows a view of the threaded bushing screwed onto the bottle neck the closure cap according to FIG. 1.

According to the drawing, a bottle 1 is provided which has a has flat shoulder 2 and has an elliptical cross-section in the area of the shoulder in etv / a. Uie shoulder 2 encloses a bottle neck 3 which is provided with an external thread 4. Near the bottle neck 3 is on the shoulder 2 a cam 5 integral with the bottle neck and shoulder is attached. A lid 7 is screwed onto the bottle 1, which has a jacket 8 whose outer dimensions juerschnitis the cross-step outer dimensions of the bottle 1 in the Shoulder 2 corresponds and whose lower edge rests on the shoulder 2 when the cap is screwed on or ends with little play in front of it. A threaded bushing is located centrally in the jacket 8 9 is provided, which receives a stopper 10 at the top to complete the bottle neck set 3 and an internal thread at the bottom 11, which is screwed into .las external thread 4.

The threaded bushing 9 forms an areal at its lower edge Stop 12, which is around the Oehäuseöicke of the threaded bushing extends in the radial direction. The / αϊ se hl ag 12 forms the vertical part of a gradation in the lower edge of the threaded bushing. From the upper end of the stop 12 forms the lower edge of the threaded bushing 8 has a section 13 which, seen in the circumferential direction + ung the threaded bushing, in the pass of the thread pitch lowers until it has reached the level of the lower T.ndes of the stop. This way ϊϊΐ down in the Threaded bushing provided a kind of recess.

Claims (3)

Protection claims 1. Bottle with closure cap, which has a threaded bushing in a jacket, which can be screwed with an internal thread onto an external thread of a piace neck that sits on a piach shoulder which, when the closure cap is screwed on and fixed in one end position, rests against a stop provided on the closure cap, characterized in that the cam (5) on the plate shoulder (2) and the stop (12) on the lower edge of the threaded bushing (9) of the Closure cap (7) is provided, the height of the stop corresponding to the lowering of the closure cap with one revolution of 360 or less. 2.
