A container (70) for constituting a formulation in liquid form, comprises an elongate outer body (71) split into a first section (72) and a second section (73), along the longitudinal axis thereof, The container (70) has an inner chamber (77) divided into a first compartment (78) and a second compartment (79) by a seal (80). Seal (80) is movable in use between a closed position, wherein the first compartment 78 and the second compartment are sealed thereby, to an open position, wherein the first compartment (78) and the second compartment (79) are unsealed and any contents therein are free to mix together in the inner chamber (77) to form the formulation. The seal (80) is movable from the closed position to the open position by rotation of the first section (72) relative to the second section (73), and the volume of the inner chamber (77) remains unchanged following unsealing. Once the seal (80) has been moved to the open position it is retained in that position. Reversal of the rotational movement causes an outer cover (74) to become detached from a tear strip (75), permitting the outer cover (74) to be removed and the formulation to be capable of being delivered from the container (70). A formulation administered from the container (70) can ensure, for example, that a precise dose of an active ingredient is delivered to a patient, where the formulation is a pharmaceutical product.

L'invention concerne un contenant (70) permettant de constituer une formulation sous forme liquide, lequel contenant présente un corps extérieur (71) de forme allongée divisé en une première section (72) et une seconde section (73) le long de l'axe longitudinal dudit corps. Ce contenant (70) présente une chambre intérieure (77) séparée en un premier compartiment (78) et un second compartiment (79) par un joint (80). En cours d'utilisation, ce joint (80) peut être déplacé entre une position fermée, dans laquelle le premier compartiment (78) et le second compartiment (79) sont scellés, et une position ouverte, dans laquelle le premier compartiment (78) et le second compartiment (79) sont descellés et leurs contenus respectifs sont libres de se mélanger dans la chambre intérieure (77) pour former la formulation. Ledit joint (80) peut être déplacé de la position fermée à la position ouverte par rotation de la première section (72) par rapport à la seconde section (73) et le volume de la chambre intérieure (77) reste inchangé après le descellage. Une fois le joint (80) placé en position ouverte, le joint est maintenu dans cette position. L'inversion du mouvement de rotation amène un couvercle extérieur (74) à se détacher d'une bande déchirable (75), ce qui permet le retrait du couvercle extérieur (74) et la distribution de la formulation contenue dans le contenant (70). Une formulation administrée à partir de ce contenant (70) peut garantir, par exemple, l'administration d'une dose précise d'un ingrédient actif à un patient, ladite formulation étant un produit pharmaceutique.
