Description

PACKAGE TO CONTAIN SEPARATE AND MIX TWO PRODUCTS

DIFFERENT

Field of the Invention

^'The present invention concerned- to a package for containing two different separate products and mixing, which keeps the two products separate for an indefinite period, without risk that may be mixed or contact each other and mix them in the same package in the time you want, for use.

More specifically, the package of the invention is of the type comprising: a container for a first product _. , equipped with threaded neck and filling mouth; a capsule containing a second product, which is open at its upper base, closed at the bottom by means of a breakable skirt, and fits tightly into the container from the mouth thereof; a container closure cap that includes a threaded wall and warranty ring; and an internal coaxial skirt that is finished off in a cutting edge for the bottom of the capsule.

Background of the invention

The packages of the exposed type are widely used in the chemical-pharmaceutical industry, for example for the distribution and sale of certain medications that include two products of substances that must be kept separate until they are taken.

A package of the type described is described for example in EP 0963325, according to which when the cap is screwed to the maximum screwed position, the inner skirt breaks the bottom of the capsule and the edge of the wall of the container capsule It is retained between the wall of the cap and the inner skirt, so that unscrewing said cap causes the removal of the container capsule. This possibility requires a special configuration of the edge of the container capsule and a good adjustment of said edge between the internal skirt and the wall of the breaker cap, to ensure the removal of the container capsule. In addition, the wall of the container capsule, at least the upper part thereof, has to have some elastic deformability in the radial direction. This package has as an inconvenience the difficulty in achieving the necessary adjustment of the upper edge of the capsule between the wall of the cap and the wall of the breaker capsule, so as to ensure the removal of said container capsule when unscrewing the cap, so that the opening from the container, for the extraction of the contents, once the mixture has been carried out, it requires in most cases to have to remove the capsule manually, once the cap has been unscrewed.

Description of the invention

The present invention has as its object a container of the type initially exposed and constituted so that, once the mixing has been carried out, by unscrewing the cap the extraction of the capsule is ensured, thus simplifying the operations necessary to achieve the pouring of the content .

In the package of the invention, the cap includes an external wall and an internal coaxial skirt. The external wall is a carrier of _' thread, for its screwed into the neck of the container, and the guarantee ring. The internal skirt has a free edge capable of breaking the bottom of the capsule when the cap is screwed to the maximum screwed position.

In accordance with the invention, the inner skirt of the closure cap has a peripheral thickening on its outer surface, while the capsule wall internally has two axially separate peripheral thickening. The external thickening of the inner skirt of the cap is of a maximum diameter slightly larger than the minimum diameter of the internal thickening of the capsule wall. In addition, the outer skirts of the skirt and the internal capsule wall are located at heights such that when the cap occupies the inviolated closing position, that is before its opening, the outer peripheral thickening of the inner skirt is faced with the inner thickening of the capsule wall, and when the cap is screwed to the position of maximum screwing, in which the rupture of the bottom of the capsule takes place, the outer peripheral thickening of the inner skirt is located immediately below the inner lower thickening of the capsule wall. To this end, the outer peripheral thickening of the skirt and internal of the capsule wall are located at heights such that when the closing cap occupies the inviolated closing position, the outer peripheral thickening of the inner skirt is faced with the inner upper thickening of the capsule wall, while when the cap is screwed to the position of the capsule bottom rupture, the outer peripheral thickening of the inner skirt is located immediately below the inner bottom thickening of the capsule wall.

In the initial assembly position of the container, once the first product has been poured into the container and the capsule is coupled with the second product inside the neck of said container, the cap is partially screwed in until the guarantee ring occupies the locking position and rests on the shoulders of the container, in which ^'the peripheral thickening of the outer surface of the inner skirt is in registry with the upper peripheral thickening of the wall of the capsule, which is achieved by the ability of elastic deformation in the radial direction of the ^" internal coaxial skirt of the cap. In this situation the peripheral thickening of the inner skirt of the cap presses radially outwardly to the wall of the capsule, which is compressed against the inner surface of the neck of the container, thus guaranteeing the tightness of the assembly.

When you want to mix the two products, the cap is screwed in completely to achieve the breakage of the guarantee ring and the bottom of the capsule. In this same operation the peripheral thickening of the inner skirt exceeds the lower thickening of the. wall of .. the capsule, thanks to the elastic deformation capacity radially of both components. Once the mixing has been carried out, unscrewing the cap allows the internal coaxial skirt of said cap to drag upwards to the capsule, until it is completely removed from the neck of the container.

The closure stopper can also have an easily broken weakening line at the bottom and in coincidence with the internal coaxial skirt ^■ , which delimits a detachable lid, to obtain an opening through which the contents of the package can be emptied , without having to unscrew the cap.

Detailed description of one embodiment

The characteristics of the cap of the invention as well as the form of use thereof will be set forth in greater detail below, with the aid of the embodiment shown in the attached drawings.

Figure 1 shows a package constituted according to the invention, which comprises a container .1, a capsule 2 and a closure cap 3.

The container "1 is intended to contain a first product and has a neck 4 with an external thread 5, immediately below which it has a peripheral rib 6 for fixing the guarantee ring of the closure cap 3, as will be explained more ahead.

The capsule 2 is a carrier of the second product contained in the container of the invention and fits tightly on the neck 4, from the mouth thereof, this capsule 2 being open at the upper base and closed at the bottom by a bottom 7 .

The closure cap 3 includes an external wall 8 and an internal coaxial skirt 9 protruding from the bottom 10 of the cap. The external wall 8 has an internal thread 11, to be screwed onto the thread 5 of the neck 4, and is also a carrier of a guarantee ring 12 separated from the wall 8 by means of a weakening line 13, this ring 12 having a rib internal ring 14.

The bottom 10 of the cap 3 can have a central opening 15, coinciding with the contour of the inner skirt 9, which will be closed by a flap 16 attached to the edge of the opening 15 by means of an easily broken weakening line 17. The placket 16 is a carrier of a traction ring 18a.

According to the invention, the inner skirt 9 has a thickening on its outer surface peripheral 18, while the wall of the capsule 2 internally has two axially separated peripheral thickening, one upper 19 and the other ^' lower 20.

As shown in Figure 7, the external thickening 18 of the inner skirt 9 of the closure cap is of maximum diameter D slightly larger than the minimum diameter d of the internal thickening 19 ^' and 20 of the capsule wall 2.

In addition, the contour bounded by the lower peripheral thickening 20 of the capsule wall may be slightly larger in diameter than the boundary delimited by. upper peripheral thickening 19.

On the other hand, the external thickening 18 of the skirt 9 and internal 19 and 20 of the capsule wall are located at heights such that when the closing cap 3 occupies the inviolated closing position, the external peripheral thickening. 18 of the inner skirt 9 is facing the upper internal thickening 19 of the capsule wall 1, while when the skirt is screwed to the position where the bottom 7 of the capsule causes rupture, the outer peripheral thickening 18 of the skirt internal 9 is located immediately below the lower internal thickening 20 of the capsule wall. Thus, when the cap occupies the inviolated closing position, shown in Figure 2, the outer peripheral thickening 18 of the inner skirt 9 is in a position facing the upper upper thickening 19 of the capsule wall. In this situation and thanks to the condition between the diameters D and d set forth above, the thickening 18 of the inner skirt -9 leans against the internal thickening 19 of the capsule wall and presses said wall radially outward, pressing it against the internal surface of the neck 4 of the container, thus ensuring the tightness between the different components.

To achieve maximum effect on _: this tight seal, the wall of the capsule 2 has an externally upper area 21, figure 1, of radial support against the inner surface of the neck, container 4, the internal upper thickening 19 of the wall of said capsule located coinciding with said support area 21, below the free edge of the wall of the ^' capsule. Below ^' this zone 21 the capsule wall reduces its outer section, so that it is separated from the inner surface of the neck 4, as shown in Figure 2, being located in coincidence with this section of wall of smaller thickness internal thickening 20.

As can be best seen in Figure 7, the external thickening 18 of the inner skirt 9 of the closure cap and the internal upper thickening 19 of the capsule wall 2 are cylindrical, while the internal lower thickening 20 of the wall of The capsule takes the form of a nerve, with a rounded section. Furthermore, the cylindrical bearings mentioned 18 and 19 are limited, at least on the opposite side through the. Which are coupled to each other, by paths 22 and 23 of conical surface, opposite.

Both the capsule 2 and the closure cap 3 are constituted of plastic material, the wall of said capsule having and the. internal skirt 9 of the closure plug certain capacity of elastic deformation in radial direction.

With the described characteristics, to reach the inviolated closing position of figure 2, the capsule 2 is coupled inside the neck 4 of the container and then the closing cap 3 is screwed in, until the guarantee ring 12 rests on the shoulders of the container 1 and nerve 14 of said ring exceeds peripheral nerve 6 of the container neck. In this position the cutting edge 24 of the inner skirt 9 of the closure cap is ^' close to the bottom 7 of the capsule 2 and the external thickening 18 of the skirt 9 in a position coincident with the internal thickening 19 of the capsule wall 2. The confrontation between both regruesamientos is achieved thanks to the partial capacity of deformation of the internal skirt 9 in radial direction. In this situation, shown in Figure 2, the total tightness of the package is ensured.

By means of the total screwing of the closure cap 2, figure 3, the breakage of the guarantee ring 12 ^' is caused, with the separation thereof, at the same time as the breakage of the bottom 7 of the capsule 2, thus obtaining both products in contact for mixing. When the inner skirt 9 is lowered, the outer thickening 18 of said skirt is achieved to exceed the inner peripheral nerve 20 of the capsule wall and be located immediately below it. This circumstance is mainly achieved due to the elastic deformation capacity in the radial direction towards the outside of the wall of the capsule 2, thanks to the reduction of. section of said wall, in the area occupied by the lower thickening 20.

The extraction of the mixture made inside the container 1 can be achieved by separating the placket 16, fractionating the ring 18a, as shown in figure 5. The contents of the container 1 will exit through the internal skirt 9 and the opening 15 obtained by separating the placket 16.

Also the extraction of the container can be achieved by the total opening of the container, by unscrewing the cap 3, as shown in Figure 6. Because the peripheral, external thickening 18 of the skirt 9 is located below the thickening or nerve peripheral 20 of the capsule wall, when unscrewing the cap 3, said external thickening 18 of the skirt 9 will rest against the rib .20 by fractionating upwards of the capsule, until its extraction is achieved as shown in figure 6 and all this because the sliding of the capsule 2 on the inner surface of the neck 4 of the container requires less effort - than the upward passage of the external thickening 18 - of the skirt 9 through the inner rib 20 of the capsule 2. The package described could lack the opening 15 and placket 16, in which case the extraction of the content would be achieved by unscrewing the cap 3, as described with reference to Figure 6.

In short, with the container of the invention, by means of the external thickening 18 of the inner skirt 9 and internal thickening 19 and 20 of the wall of the capsule 2, there is a means that ensures the extraction of the capsule by unscrewing the cap of closure 3, without risk of said capsule being retained by the neck 4.
