Abstract

A bottle (1) for cosmetic and pharmaceutical products, hair dyes and the like having separate components, comprising a container body (2) for a first component which has a first opening (10) for accommodating a tear-open body (11) for containing a second component and a second opening (20) for dispensing the mixed product.

Description

The present invention relates to a bottle for cosmetic and pharmaceutical products, hair dyes and the like, having separate components.
It is known that in many fields of application it is necessary to have products formed by means of two components which must be mixed together substantially when they are used.
Currently available solutions use vials for containing a first component which are closed by a plug-like element provided with a compartment having a tear-open bottom, inside which a second component is provided which, at the time of use, can be introduced in the region where the first component is provided by tearing open the bottom.
This solution is usable only for single-dose products, since in order to access the mixed product it is necessary to fully remove the plug inside which the second component was contained.
Obviously, this method is not very practical and also constitutes a severe limitation to the use of two-part products, such as for example whenever one has cosmetic or pharmaceutical products in which the active principle must be mixed shortly before use.
The aim of the present invention is to eliminate the above-mentioned drawbacks by providing a bottle for cosmetic and pharmaceutical products, hair dyes and the like having separate components in which it is possible to separate the mixing of the second component from the dispensing of the mixed product.
Within the scope of this aim, a particular object of the invention is to provide a bottle which allows to contain an amount of product which can be used in a plurality of successive occasions without thereby having to remove the plug or similar elements.
Another object of the present invention is to provide a bottle which, thanks to its particular constructive characteristics, is capable of giving the greatest assurances of reliability and safety in use.
Another object of the present invention is to provide a bottle for cosmetic and pharmaceutical products, hair dyes and the like having separate components which can be easily obtained starting from commonly commercially available elements and materials and is also competitive from a purely economical point of view.
This aim, these objects and others which will become apparent hereinafter are achieved by a bottle for cosmetic and pharmaceutical products, hair dyes and the like having separate components, according to the invention, characterized in that it comprises a container body for a first component which has a first opening for accommodating a tear-open body for containing a second component and a second opening for dispensing a mixed product obtained by mixing said first and second components.
Further characteristics and advantages of the present invention will become apparent from the following detailed description of a bottle for cosmetic and pharmaceutical products, hair dyes and the like having separate components, illustrated only by way of non-limitative example in the accompanying drawings, wherein:
Figure 1 is a partially sectional view of the bottle according to the invention, with the first and second components separated from each other;
Figure 2 is a schematic view of the mixing of the two components;
Figure 3 is a schematic perspective view of the bottle.
With reference to the above figures, the bottle for cosmetic and pharmaceutical products, hair dyes and the like having separate components according to the invention, generally designated by the reference numeral 1, comprises a container body 2 which is closed by a cap 3 which can be applied in a per se conventional manner.
The container body 2 contains a first component, constituted for example by a liquid or the like, which is schematically designated by the reference numeral 4.
The container body 2 forms a first opening 10 in which a tear-open body 11 is inserted; the body 11 is provided with a bottom 12 which is connected to the body 11 by means of a prefracture line 13.
A hollow cylindrical piston 14 is slideable inside the body 11 and has an obliquely-cut end 15 which is designed, by applying pressure to the hollow cylindrical piston, to tear the prefracture line 13, breaking it and causing a second component 17 contained in the body 11 to pass into the first component 4 in order to mix the product.
Advantageously, the second component 17 is constituted for example, in the case of cosmetic or pharmaceutical products or products for hair dyes and the like, by an active principle which is mixed with the liquid 4 at the time of use.
An important feature of the bottle according to the invention resides in the fact that the container body 2 forms a second opening 20 which allows to dispense the mixed product externally without thereby having to remove the body 11.
Advantageously, a dispenser 21, for example of the pushbutton type, is provided at the second opening 20.
With the described arrangement, a bottle is accordingly provided which allows to mix the second component without then having to remove the plug inside which said component was contained.
It is also possible to provide a bottle which can contain a plurality of doses, since dispensing is performed through an opening which is different from the one used for mixing.
From the above description it is evident that the bottle according to the invention achieves the intended aim and objects, and in particular it is noted that it achieves results in terms of reducing pollution effects, i.e., achieves more efficient waste management.
In practice, the materials used, so long as they are compatible with the specific use, as well as the contingent shapes and dimensions, may be any according to requirements.
