Device for packaging two products to be mixed and for dispensing the mixture of these products

Abstract

Device including a bottle having two open ends and a central body receiving a first product, one end of the bottle has an orifice receiving a stopper which contains a second product to be mixed with the first, another end of the bottle has an orifice receiving a removable cap provided for withdrawing the mixture after removal of the cap.

Description

TECHNICAL FIELD[0001]The present invention generally concerns a device for packaging two products to be mixed, at least one thereof being a liquid product, and for dispensing the mixture of these products. One particular, but non-limiting exemplary application of the subject of this invention is a combined device intended for the extemporaneous preparing of medicinal products in the liquid state, and for the secure withdrawing of the prepared liquid preparation from the device. The problem underlying the invention is set forth below with reference to this particular application.BACKGROUND[0002]The oral dosing of medicinal products in tablet form, in the solid state, is often difficult for children and the elderly notably for reasons of palatability, the size of the tablets often being too large. In addition the doses to be prescribed are not uniform and current tablets do not allow personalized dose adaptation.[0003]Therefore, liquid forms of medicinal products can improve the palat...

AI Technical Summary

Benefits of technology

[0017]Regarding the other end of the bottle which receives the cap, this end may also carry or itself form a section reducer with a central orifice having a diameter corresponding to the diameter of a dosing syringe which can be used to withdraw the mixture in secure, sterile manner with no risk of leakage.

Problems solved by technology

The oral dosing of medicinal products in tablet form, in the solid state, is often difficult for children and the elderly notably for reasons of palatability, the size of the tablets often being too large.

In addition the doses to be prescribed are not uniform and current tablets do not allow personalized dose adaptation.

However, from an industrial viewpoint, liquid forms are fairly complicated to prepare, chiefly having regard to the stability of the active ingredient in the liquid.

In these patents, the mixture is prepared through voluntary action on the part of the user, and the disadvantages of conventional extemporaneous preparations are not eliminated: risk of contamination for sterile products, risk of loss of part of the components, risk of using only a single component and, in general, difficulty in applying or using the method to be followed to obtain proper mixing.

This latter form of embodiment remains fairly difficult to manipulate and comprises risks of product leakage when placing one bottle over the other and at the time of dispensing the prepared mixture.

In addition, the applications thereof are limited to the mixing together of liquid products.
