Description
- f SCZEW CA? W1-ri4 5-Top -DEvkcr-- t, 1 0 2 -
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.
Plastic caps applic.able 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 upon screwing on the cap the resistance of the threads of the bottle and of the cap itself is exceeded and the socalled 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 negative consequences.
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 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 unquestionable 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 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 oversize the whole and this involves technical and economic incon 0 1 3 veniences.
The cap that the invention proposes is of the type described but it includes a stop device which definitively 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, preventing said cap from continuing to screw before reaching a side overforce on the threads.
-As it has been said, said stop device is applicable to plastic caps, and specithcally to those that form a cap type body with an inner thre-ad 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.
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 thickening located in the inner contour of the cap, prEferably in correspondence with the inner edge established between the bottom and the flap or inner flange of said cap, this 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 752 and its inner radius has to be less than half of the outer diameter of the thread of the neck of the bottle.
In order to complement the description which is going
0 4 - to be made hereinafter and for the purpose of providing a better understanding of the characteristics of the invention, the present specification has a single sheet of drawings attached to it. On the basis of the drawings the features object of the invention will be understood more easily.
BRIEF DESCRIPTION OF THE DRAWINGS
Figure 1 shows a sectional view, according to a vertical and diametral plane of the cap coupled to the neck of a bettle, cap which includes the stop device made in accordance with the object of the invetion.
---Figure2 shows a sectional view, in accordance with a horizontal plane, in other words, perpendicular to the axial axis of the whole which constitutes the coupling between the cap and the neck of the bottle.
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 thread 2 provided on the neck of a bottle 3, with the particular feature that the latter is to contain liquids, such as soft drinks or the like.
The cap 1 that forms a cap, which is conventionally complemented and in correspondence with its bottom edge with a sealing ring 4 provided with a ring-shaped tooth 5 interlocks in the transversal rib 6 of the bottle 3, while in the bottom of the whole there is a flap or concentric partition 7 between which and the inside side surface of the cap fits the top edge of the neck of the bottle 3.
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 the left part 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, 0 4 determining an obstacle resistant to the turning of the cap in the last screwing phase. Besides this thickePing 8 covers an arc of approximately 759 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 point will be reached in which the first section of the thread 2' will be at the thickening 8, impeding its advance until reaching a resistance such that the force needed to continue screwing on the cap by hand exceeds that which is established as a safety standard.
-----Logically said force is borne only by the thickening 8 and by the first section 21 of the thread 2 corresponding to the bottle 3, all in such a way that the threads of the bottle and of course the ones of the cap will not bear any side overpressure, thus attaining an indefinite duration of the sealing of the cap and a a guaranteed conserving of the contained liquid, also avoiding all risks of leakage.
