A container (10) having a curved bottom (12) and base cup (20) which allows the container to stand upright. The container and base cup are fitted together by a mechanical engagement- (32) having portions on the container and base cup. The mechanical engagement of the container is disposed within the bottom cone of the container. The mechanical engagement of the base cup is cantilevered from the bottom of the base cup. Such disposition reduces stress at the interface between the side wall of the container and edge of the base, providing for a smoother transition and better appearance. Also, this disposition provides resistance to separation of the container and base cup during drop impact. The bottom of the container may be curved and have a well therein for receiving the contents of the container and a dip tube.

L'invention porte sur un conteneur comportant un fond incurvé et sur une coupelle de base qui permet au conteneur de tenir debout. Le conteneur et la coupelle de base sont ajustés l'un à l'autre par un engagement mécanique comportant des parties sur le conteneur et la coupelle de base. L'engagement mécanique du conteneur est disposé à l'intérieur du cône inférieur du conteneur. L'engagement mécanique de la coupelle de base est en porte-à-faux à partir du fond de la coupelle de base. Cette disposition réduit les contraintes à l'interface entre la paroi latérale du conteneur et le bord de la base, produisant une transition plus douce et un meilleur aspect. Cette disposition produit également une résistance à la séparation du conteneur et de la coupelle de base durant un impact de chute. Le fond du conteneur peut être incurvé et comporter un puits à l'intérieur de celui-ci pour recevoir le contenu du conteneur et d'un tube plongeur.
