A package for companion products has two containers (102, 104), each comprising a mating formation (408, 502) protruding in a direction toward the other container and defining a mating surface facing at an angle to the direction of protrusion and engaging the mating surface of the other container. Each container has a generally flat bottom and a center of gravity in vertical alignment with the generally flat bottom, whereby each container can stand independently of the other container. The shape of each container is the same as the other, and the containers are attached to one another. The shape enables the mating surfaces to be brought into engagement with one another by movement in a plane parallel to the bottoms of the containers.

1. A package for companion products having a first container and a second container, each container comprising:a body, the body including a mating formation protruding from the body in a direction toward the other container, the mating formation having a mating surface facing at an angle to the direction of protrusion and engaging the mating surface of the other container, wherein the mating surfaces on the first and second containers are the same as one another; a first generally flat surface adjacent to a first side of the mating formation, and a second generally flat surface adjacent to the mating formation on a second side of the mating formation, opposite to said first side; a generally flat bottom; a center of gravity, the center of gravity being in vertical alignment with the generally flat bottom, whereby each container can stand independently of the other container; and a shape, the shape of the first and second containers being the same as one another, wherein the containers are attached to one another and the bottom of each container lies in a common plane. 2. The package of claim 1, wherein each said container further comprises a front defining:a recessed grip; a first shoulder positioned above said recessed grip; and a second shoulder positioned below said recessed grip. 3. The package of claim 2, further comprising a shrink-wrap extending around the containers and attaching the containers to one another, the shrink-wrap contacting the recessed grips and terminating, in a direction transverse to the direction of extending, below said first shoulder and above said second shoulder.4. The package of claim 2, wherein each container further comprises a back and opposite sides, and the mating formation is positioned on the back, generally midway between the opposite sides.5. The package of claim 1, wherein each container further comprises a narrow side and a wide side.6. The package of claim 1, further comprising an adhesive attaching the containers to one another.7. The package of claim 6, wherein the adhesive is on said mating surfaces.8. The package of claim 1, further comprising a shrink-wrap extending around the containers and attaching the containers to one another.9. The package of claim 8, wherein said shrink-wrap comprises a label.10. The package of claim 1, wherein each container has a front, a back and opposite sides, and the mating formation is positioned on the back, generally midway between the opposite sides.11. The package of claim 1, wherein each container further comprises a neck offset from the vertical centerline of its container.12. The package of claim 11, wherein the neck of each container has a structure for retaining a closure.13. The package of claim 11, wherein the necks are spaced from one another.14. The package of claim 1, wherein each container has a curved surface opposite to the mating formation, the curved surface being made of a pliable material such that the curved surface is deflectable by squeezing by hand.15. A package for companion products having a first container and a second container, each container comprising:a body, the body including a mating formation protruding from the body in a direction toward the other container, the mating formation having a mating surface facing at an angle to the direction of protrusion and engaging the mating surface of the other container; a first generally flat surface adjacent to a first side of the mating formation, and a second generally flat surface adjacent to the mating formation on a second side of the mating formation, opposite to said first side; a generally flat bottom; and a shape, the shape of the first and second containers being the same as one another, wherein said shape comprises means for enabling the mating surfaces to be brought into engagement with one another by movement in a plane parallel to the generally flat bottoms of the containers when the generally flat bottoms are in a common plane. 16. The package of claim 15, wherein the first and second generally flat surfaces of the first container are in substantially flush contact with the second and first surfaces, respectively, of the second container.17. The package of claim 16, wherein said first and second generally flat surfaces lie in planes that are parallel to and spaced from one another.18. The package of claim 15, wherein each container further comprises a center of gravity, the center of gravity being in vertical alignment with the generally flat bottom, whereby each container can stand independently of the other container.19. A method of in making a package for companion products, wherein the package has a first container and a second container each having an outer surface and a generally flat bottom, the method comprising:providing each container with a shape the same as the shape of the other container and with a protrusion extending in a direction outward from the outer surface; providing each protrusion with a mating surface facing in a direction at an angle to the direction of protrusion extension, wherein the mating surfaces on the first and second containers are the same as one another, and wherein each container has a first generally flat surface adjacent to a first side of the protrusion, and a second generally flat surface adjacent to the protrusion on a second side of the protrusion, opposite to said first side; orienting at least one of the containers such that the generally flat bottoms lie in the same plane and each protrusion extends generally towards the other container; moving at least one of the containers toward the other in a plane parallel to the generally flat bottoms such that the mating surfaces come into engagement with one another; and attaching the containers to one another so that the first and second generally flat surfaces of the first container are in substantially flush contact with the second and first surfaces, respectively, of the second container. 20. The method of claim 19, wherein the movement comprises a single straightline movement.21. The method of claim 19, wherein the step of attaching comprises adhering the containers to one another with an adhesive.22. The method of claim 21, wherein the mating surfaces are adhered to one another.23. The method of claim 19, wherein the step of attaching comprises positioning a shrinkwrap around and in contact with the containers.24. The method of claim 23, further comprising:providing a recessed grip in each container, wherein the step of attaching comprises positioning the shrink wrap in the recessed grips. 25. The method of claim 19, wherein said moving is in a direction transverse to the direction of protrusion extension.26. The method of claim 19, wherein the step of orienting comprises sensing the orientation of said first container relative to said second container, and turning said first container to a position in which the mating surface of the first container contacts the mating surface of the second container after the moving step is performed.27. The method of claim 26, wherein said sensing comprises detecting the position, relative to the direction of motion of said first container, of a neck of the first container that is offset from the vertical centerline of the container.28. The method of claim 19, wherein the step of attaching comprises gluing the containers to one another.29. The method of claim 19, wherein the step of attaching comprises positioning a shrink wrap around said package; andaffixing a shrink wrap to maintain the positions of the said containers in said package. 30. The method of claim 19, further comprising employing the engagement of the mating surfaces with one another to stop said moving.
