Abstract
ABSTRACT
The stop device for cap threads is preferably applicable to plastic caps which are coupled by screwing on the corres-ponding neck of a bottle containing liquids.
The device consists of a thickening or projection (8) provided in the inner part of the cap (1), specifically in the intersection part between the side surface of said cap and the bottom of the same. When the cap (1) is screwed on the neck of the bottle this thickening (8) stops against the first thread (2') which the neck of the bottle has, consti-tuting an obstacle resistant enough to prevent the cap (1) in its last screwing phase from continuing screwing on the neck.

2~2~7 , :
OBJECT OF THE INVENTION
As is expressed in the title of this specification, the present invention refers to a stop device for cap threads, which has been conceived and made in order to prevent the ~ cap from screwing beyond some pre-established limits.
-, The stop device is applicable to the type of caps made out of plastic and which screw on a neck of bottles which preferably contain carbonated products, such as soft drinks :~
and the like.
; BACKGROUND OF THE_INVENTION
Plastic caps applicable to bottles as it has been stated above, when they are used several times, too easily have the ;
inconvenience that upon exerting a moderate rotating force ~
15 upon screwing on the cap the resistance of the threads of the ; ;
bottle and of the cap itself is exceeded and the so-called ;~
state of a "crossed thread" is reached. Thus, the cap and the `~
~<~ bottle become useless. Besides, on occasions the contents .. .. . ..
or the carbon dioxide leak and this has the corresponding nega-tive consequences.
~l In view of this problem some standards of quality which the type of caps which we are referring to should meet were -set down. These standards of quality established some minimal .i,,l.,~ll .
forces which all caps used to seal bottles for liquids should resist.
Now then, due to the nature of the material used to make caps, it is unquestionabIe that at certain temperatures the required standards of quality can be met on the basis of a specific size and design of the cap. Now then, above a certain 1 30 temperature, and due to the nature of the material, as it has been said, the same force stood before will now cause and in these conditions of higher temperature the thread no longer fits properly.
Therefore, cap manufacturers have been forced to over-size the whole and this involves technical and economic incon-2 ~ 7 1 veniences.
D~SCRIPTION OF THE INVENTION
- The cap that the invention proposes is of the type described but it includes a stop device which definitively . 5 solves the problems and conveniences cited above and all of this without the temperature having an influence on the greater or lesser effectiveness of the system.
In this sense, the stop that the cap has remains placed at the pitch of the thread of the neck of the bottle, prevent-ing said cap from continuing to screw before reaching a sideoverforce on the threads.
As it has been said, said stop device is applicable to plastic caps, and specifically to those that form a cap type i~ body with an inner thread for its coupling to the inner thread of the bottle, with the particular feature that said cap is ~, conveniently provided on its bottom edge with the respective sealing ring, which includes a tooth which interlocks in a transversal rib of the bottle.
~,j Likewise this cap has an inner ring-shaped flange or partition for its adjustment to the mouth of the bottle, in other words, the top edge of the bottle remains inserted between the flange or concentric partition and the side . ~ .
surface of the cap.
As to the stop device itself, the same consists of a "~'t 25 thickening located in the inner contour of the cap, pre~erably ~-, in correspondence with the inner edge established between the bottom and the flap or inner flange of said cap, this ~j all for the purpose that the thickening remains placed at the pitch of the first single thread of the neck of the bottle, determining an obstacle resistant to the turning of the cap in the last screwing phase.
Preferably, the stop covers an arc of approximately 75 and its inner radius has to be less than half of the outer diameter of the thread of the neck of the bottle.

BRIEF DESCRIPTION OF THE DRAWINGS
Figure 1.- It shows a sectional view, according to a vertical and diametral plane of the cap coupled to the 10 neck of a bottle, cap which includes the stop device made ~ in accordance with the object of the inve~ion.

DESCRIPTION OF A PREFERRED EMBODIMENT
In view of these figures, one can see how the stop ? device that the invention proposes is applicable to plastic~?` caps 1 which are to be screwed on the corresponding single 20 thread 2 provided on the neck of a bottle 3, with the parti-~ ~ cular feature that the latter is to contain liquids, such ~`

The stop device consists of a thickening 8 provided ?
in correspondence with the inner contour of the cap 1, preferably in the inner edge established between the bottom and the flap or concentric partition 7, as one can see very well in thè left ~art of figures 1 and 2.
Said thickening 8 is placed at the pitch of the first section 2' of the thread 2 of the neck of the bottle 3, ~i D~ ~ ~

determining an obstacle resistant to the turning of the cap in the l~st screwing phase. Besides this thickening 8 covers an arc of approximately 75 and has a bottom inner `,~ radius half the outer diameter of the thread 2 of the neck of the bottle 3.
In this way, when the cap 1 is screwed on the neck of ~ the bottle 3, a po~int will be reached in which the first fi section of the thread 2' wl].l be at the thickening 8, im~ ::

of the contained liquid, also avoiding all risks of leakage. ~.
