An end piece is adapted for connection and fluid communication with a dip tube for drawing in matter through suction. The end piece includes an upper part and a lower part. The upper part is connected with the bottom end of the tube. The lower part includes an upper base, a lower base and an enclosing wall by which the lower base is joined to the upper base. The enclosing wall defines a hollow space between the upper base and the lower base. The lower base is larger in area than the upper base such that the hollow space is tapered toward the upper base. The lower base provides an opening for matter to enter.

1. A container including: a hull defining an interior space for storage;a dip tube assembly for drawing in matter through suction from the container and configured to establish fluid communication with the interior space, the dip tube assembly including: a fitting configured to secure the assembly to the hull;a tube including a top end and a bottom end, the top end of the tube configured to be connected to the fitting, the tube comprising a longitudinal axis extending through the tube between the top end and the bottom end, and the tube being rotatable relative to the hull about said longitudinal axis; andan end piece including: an upper part configured to be connected with the bottom end of the tube, and comprising a central axis arranged substantially concentric with the longitudinal axis of the tube; anda lower part including an upper base, a lower base and an enclosing wall by which the lower base is joined to the upper base, the enclosing wall defining a hollow space between the upper base and the lower base, the lower base being larger in area than the upper base such that the hollow space is tapered toward the upper base, the lower base providing an opening for matter to enter, the upper base and the lower base being at a non-zero angle relative to one another,wherein the upper base comprises a first perimeter that abuts a second perimeter of the lower base, the lower base being shaped such that a radially outermost end of the second perimeter is farthest from said central axis of the upper part to define a maximum radius of the end piece; anda vacuum source configured to draw matter into the end piece,wherein the dip tube assembly is positioned in close proximity to a wall of the hull and a maximum radius of the dip tube assembly within the interior space is constrained by the maximum radius of the end piece, such that the dip tube is rotatable 360 degrees relative to the hull without contacting said wall of the hull. 2. The container of claim 1, wherein the lower part is shaped as a truncated portion of a cone. 3. The container of claim 1, wherein the opening has an oval shape. 4. The container of claim 1, wherein the fitting is elbow-shaped. 5. A container including: a hull defining an interior space for storage; anda dip tube assembly for drawing in matter through suction from the container, the dip tube assembly being in fluid communication with the container, the dip tube assembly including: a fitting configured to secure the assembly to the container, the fitting configured to rotate 360-degree about the container;a tube including a top end and a bottom end, the top end of the tube connected to the fitting; andan end piece including: an upper part connected with the bottom end of the tube, and comprising a central axis; anda lower part including an upper base, a lower base and an enclosing wall by which the lower base is joined to the upper base, the enclosing wall defining a hollow space between the upper base and the lower base, the lower base being larger in area than the upper base such that the hollow space is tapered toward the upper base, the lower base providing an opening for matter to enter, the upper base and the lower base being at a non-zero angle relative to one another, wherein the upper base comprises a first perimeter and the lower base comprises a second perimeter, the lower base being shaped such that a radially outermost end of the second perimeter is farthest from said central axis of the upper part to define a maximum radius of the end piece, wherein the hull includes a wall adjacent to the assembly and the assembly is mounted to the container in close proximity to the wall, and spaced a distance from the wall greater than the maximum radius of the end piece such that the radially outermost end of the lower part can be rotated 360 degrees without contacting the wall. 6. The container of claim 5, wherein the end piece is oriented such that the upper base is substantially parallel to a ground. 7. The container of claim 5, wherein the fitting is mounted from above the container. 8. The container of claim 5, wherein the assembly is dimensioned such that the opening is near a floor of the container.
