ORlQSNAL INSPECTED

According to the main application, the device for • Closing bottles and the like. For storing Products which comprise at least two components, which are stored separately until the moment of use should be, with one, on the bottle mouthpiece screw-on screw cap is provided in the manner designed that two container parts are provided which can be pushed into one another in a sealing manner, one of which is a container part is open at the top and has a closed bottom and in the bottle mouthpiece can be used and means for locking on the Flasehenmundstüek owns, and change the other part of the container the end facing the first container part has tear-open means for the container bottom of the other container part. Here, the means for locking one container part on the bottle mouthpiece consist of a protruding, flange resting on the bottle mouthpiece. The other container part has on the former Container part facing end a protruding tip as a tear-open means for the bottom and the container part has at the end facing the other part of the container a boundary running obliquely to the tip, Furthermore, the other container part is open at the end facing one container part and at the other end Formed closed at the end. In this way, not only is a secure, tight seal of the two containers for separate storage of the components achieved, but also the possibility of repeating the main container to be able to close when the other container is removed.

409833/0267

According to the present invention is the screw cap of the type described is also provided with a safety device that enables, in a known manner, to be able to determine whether the screw cap has already been opened or not. Such a Safety lock makes this special Difficulties because there are two different positions for the screw cap, namely the position of the Screw cap with inserted auxiliary container and the further position of the screw cap where the auxiliary container no longer exists.

The invention is characterized in that the screw cap for the safety lock has a collar obtained, which has a height that is greater than the height difference between the position 'the screwed Screw cap with the auxiliary container inserted and the one without this container. The covenant is a Associated ring with sawtooth-like teeth on the circumference and the collar has elastically deformable projections on its inner circumference, which are formed with the saw teeth grab together. In this case, tear-off bars known per se are arranged between the screw cap and the collar. The elastically deformable projections should be inclined in the direction of the steep flanks of the saw teeth get lost.

The inside of the bottle or the like has a partially cylindrical neck or mouthpiece 12 of a given inner diameter D (FIG. 6) and has an external thread 14. The final edge should be as flat or flat as possible. be even.

The actual device comprises in combination the parts 1δ and 20, which are the auxiliary container for storage a component of the product, which is supported by a further component (generally consisting of a solution or dispersion liquid), which in turn in the main container realized by the bottle 10 should be kept physically hermetically separated.

The part 18 comprises a small transparent container body 22, which has a bottom 2h , which can thereby be opened or cut off circumferentially, since at 26 at its connection zone with the named-

409833/0267

th container body 2? is weakened. The above-mentioned container body 22 is provided with a flange 28 at the top} whose lower ring-shaped surface can be equipped with elevations or ribs JO (FIG. 2) to rest on the edge Io of the mouthpiece or is flat, as in J> Q 'in Fig. JJ indicated.

Said flange 28 has an annular groove 52 ₃ which in turn surrounds an inner elevation which is used for sliding and seals with part 20. Furthermore. the upper fraction 22a of the small transparent body 22 is so dimensioned that it conforms precisely to it, ie with sufficient tightness to form a hermetic seal with the interior 36 (FIGS. 2, 5 and 6) of the customer of the bottle the lower part of the body 22 has a smaller diameter and is connected to the upper part 22a via a conical or appropriately curved section, in order to allow the part 1δ 'to open into and deeply into the mouthpiece (Fig. 1 and 4 ), taking up minor coaxial errors in the insertion process and thus generally facilitating the use of mechanized systems for such insertion and the carrying out of the packing work in general.

The good sealing contact between the transparent container 18 and the interior 36 of the dog piece, so that the mentioned part also secures the closure of the main container individually, can be ensured by lamellae or other elevations.

For example, according to the Aus-409833/0267 shown in FIG

leadership change of the upper part 22a of the body 22, which may possibly have a smaller diameter than the inner diameter D of the mouthpiece, at least provided with a lamella serving as a support or with a rib construction 3> 8. The other part 20 forms the Tear means of the bottom 24 of the part 18, in addition it forms with the latter the small auxiliary container. That said part 20 is in turn designed as an upside-down cylinder, includes a top through a bottom 42 closed hollow body 40, which is preferably provided with a slightly protruding edge 44 is and is diametrically dimensioned so that it fits tightly and sealingly in the inner elevation .J4 of the part 18 starts. '· -. - ......

The lower part 40a of the body 40 has a slightly smaller diameter and is tapered with the upper part 40 connected to the confluence of the part 20 in the part 18 for the aforementioned Zv; corner for insertion of the latter part 18 to facilitate.

As can be seen particularly from FIGS. 2 and 4, the edge of the lower open end of the body 40, 40a inclined and comprises, as indicated at 46, an edge-shaped edge with a tip ¹ IQ ends so that das.Abschneiden and opening of the bottom 24 is effected when the part 20 is pushed into the part 18, as shown in FIG.

The said small compound auxiliary container is in turn a screw cap 50 to form the device assigned. This screw cap comprises an upper closed base 52, a tubular circumferential

409833/0267

part 54, which is preferably provided with external toothing or corrugation or has such a design that allows a secure grip and a rotation of hard. The screw cap has a thread 56 on the inside which is suitable for engaging the thread 14 of the mouthpiece 12. The sight capsule 50 also includes within its bottom 52 a tubular inner extension 58 * which is preferably provided with an initial frustoconical grip section 58a, the outer diameter of which is equal to the inner diameter D of the mouthpiece 12 (FIG. 6), so that the said extension 58 is fixed adjacent and therefore sealingly inserted into the interior 36 of said mouthpiece.

However, the inside diameter d of the same extension 58 is larger than the maximum diameter of the part 20, so that any contact with the end edge 44 of said Teües is excluded. The lower edge 60 of the same lug 58 forms a flat annular surface, which is dimensioned so that it is the flat, annular through the flange 28 of part 18 of the small Auxiliary container exhibited surface 62 axially opposite. The height h (Fig. 5) of the interior of the mentioned approach 58 resulting recess is slightly larger than the projection S (Fig »1), the Part 20 of the small container has opposite the annular plane 22 which is the tip of the other part 18 defines when the said part 20 is inserted sealingly in part l8 to the sealing of the small container, but in incomplete Dimensions, i.e. that the tip 48 does not come into contact with the weakened part 26 of the base 24.

tion arrives and the said soil is preserved intact.

From the above and in particular from the geometrical and dimensional relationships of the above considered various components of the device according to the invention and from the comparative observation of the various figures contained in the accompanying drawings show the possibilities and advantages of the Invention clearly emerges.

Taking into account the packaging conditions and the long storage times of the product consisting of separate components, the device according to the invention is identified as shown in FIG. 1. The two parts 18 and 20 of the small container are inserted into one another in a sealing manner and therefore ensure the insulation of the component enclosed in the container formed in this way both from the external environment and from the other component enclosed in the bottle 10 below. The inside of this bottle is also by tightening the part. 1δ sealed in the inner part 36 of the mouthpiece 12 of the bottle. The second part 20 protruding to the extent S from part 18 does not damage the bottom 24 of the transparent container. Tightening and screwing down the screw cap 50 brings the annular surface 60 into contact with the underlying annular surface 62 of the flange 28, the underlying annular surface JO or JO 'of which rests on the rim 16 of the mouthpiece 12. Said screw cap 50 therefore ensures the stability of the closure without otherwise affecting the

409833/0267

Inner part 20 to act, the protruding part of which • embedded within the tubular extension 58 is, therefore, as a limit to the depth of screwing and pulling the capsule acts. The unauthorized or premature removal of the screw cap can be prevented or are indicated in a manner known per se by further external means that are prior to voluntary removal of the said screw capsule are to be torn or removed.

The screw cap is used to prepare the product removed and the protruding part of the tear-off device 20 is freely accessible to point it in the direction of A-through to act a manually exerted pressure / whereby the effect shown in Fig. 4 of the opening of the Soil 2% is reached. The contents of the auxiliary container falls in direction 3 into the bottle below and forms the desired suspension, solution or combination the components of the product »During the process the bottle remains tightly closed» This is due to the Diehi setting of part 18 ins Mouthpiece and part 20 in the. Part l8 ensures.

To consume the contents of the bottle prepared in this way, the parts 18 and 20 mentioned are pulled out together and removed, thereby releasing the opening of the mouthpiece (FIG. 6). The available and unaffected remaining Schraubkapsel 50 is then used to make the bottle to be closed again, (represented in Fig. 1) which contrasted by the absence of the small Innenbehalters Tiefanschrauben the Schraubkapsel is possible in such a way that dev annular extension 58 for his part with close

4Q9833 / Q267

Plant rotates into the interior 36 of the mouthpiece, wherein the resulting subsequent hermetic sealing condition is shown in FIG.

In Figs. 7 to 10, the screw cap 50 is with a Safety device provided, through which it can be seen whether the screw cap was open or not, Such safety devices are known per se. Since the screw capsule has different positions on the Mouthpiece of the bottle, depending on whether the auxiliary container is present or not, the screw cap 50 requires a special design for the Safety device. '-'-... "".

As can be seen from a comparison of FIGS. 1 and 5, the screw cap 50 assumes a position in said first and second operating conditions which axially with respect to the screw mouthpiece 12 of the bottle is different, the distance or difference axially between these positions being approximately A in Fig. 7 is indicated. However, the safety and guarantee means whether the screw cap has already been unscrewed has been or not, no obstacle to such a variation in position and operation represent. It must, however, the integrity of the content in the first position (Fig. 7) of the original closure be guaranteed.

These means are implemented by a guarantee collar 6h, which is firmly connected to the screw cap 50 and in one piece, and by a ring 65 with saw teeth 66, which are firmly connected to the mouthpiece 12 and provided under the thread 14 of the same. The said

409833/0267

The collar 64 has a number of internal projections 68 that elastically deformed v / ground, so that the rotation in direction B (Flg. 10), and thus in the screwing direction the capsule 50 on the thread 14, can be made possible without the integrity of the screw cap 50, 64 is damaged, while the collar 64 is not individually rotatable in the opposite direction.

Said collar 64 is connected to the lower edge of the screw cap 50 by means of a ring 70 which breaks easily. E.g. this ring consists of a series of small webs 72 that run radially and with one another - Are connected to the other and their mechanical strength for the movement in direction B of the said covenant around the annular projection with saw teeth 66 is sufficient. But it is stronger when you have limited use makes by hand on the capsule 50 in the direction of unscrewing. When the broken capsule however, the first time it is unscrewed, the connection at 70 between the capsule and the collar 64 is made broken, and the capsule is consequently individually rotatable, unscrewable and removable, as Fig. 8 shows. The collar 64, which is so separated, can remain in place and ropes (FIGS. 8 and 9), it can also be removed or be destroyed.

When the Schraubkapsel 50 is screwed on again to the extreme (Fig. 5)> the subsequent hermetic sealing is not hindered by the presence of the annular projection 66th The original screw cap must be sized so that under the conditions of the initial closure (Fig. 7) between the

3/0267

lower edge * jk (FIG. 8) and the edge or the surface 76 of the screw cap 50 or of the annular projection 66, there is an axial gap which is approximately equal to A (FIG. 7). This can be achieved if the said band 6k is provided with axial dimensions greater than A with a sufficient oversize so that the use of the inner projections 68 of the collar with the saw teeth of the annular projection 66 is possible.

The screw cap can be made from any suitable plastic consist of injection molding.
