said contoured surfaces of said female recess portion comprising a generally planar and vertical inner end wall extending inwardly at an angle greater than ninety degrees from said front wall and a generally planar inner back wall surface,

said contoured surfaces of said female recess portion further comprising an elongated longitudinally contoured tapered inner base surface having a lower arcuate lip portion extending inwardly from said front wall, and an elongated longitudinally contoured tapered inner top surface having an upper arcuate lip portion extending inwardly from said front wall;

said contour of said male portion comprising a generally planar front surface and a generally planar and vertical inside surface extending outwardly at an angle greater than ninety degrees from said front wall, and said male portion further comprising oppositely disposed colateral longitudinally contoured elongated upper and lower engagement surfaces extending between said generally planar front surface and said front wall, said male portion further comprising a vertical outside surface extending in the same plane as said second side wall of said container, and

wherein said container is adapted to engage a second identical container, wherein the following conditions are met when said container is in abutting contact with the second identical container:

a. said male lug portion angularly disposed vertical inside surface of said container abuts said angularly disposed inner end wall of said female recess portion of the second identical container,

b. said male lug portion upper engagement surface abuts said upper arcuate lip portion of said female recess portion,

c. said male lug portion lower engagement surface abuts said lower arcuate lip portion of said female recess portion, and wherein

d. said vertical outside surface of said male portion of said container is positioned in the same plane as said first side wall of said second identical container to provide visual confirmation of said male portion positioned within said female portion when viewed from one of said first side of said container and said second side of said container.

2. The modular molded bottle container set forth in claim 1 wherein said inner base and top surfaces and said inner end wall surface intersect the plane of said front wall.

3. The modular molded bottle container set forth in claim 1 wherein said front surface of said male lug portion is of a known surface dimension less than that of said inner back wall surface of said female recess portion.

4. A modular molded container system comprising a pair of identical bottle containers of predetermined volume, each of said bottles having a top and bottom with multiple adjoining integral walls therebetween, wherein the integral walls include a front wall, a rear wall opposite said front wall, and a first and second oppositely disposed side walls extending between said front and rear wall, wherein said front wall is generally flat and planar, a neck portion extending from said top defining an opening therein, a generally flat planar surface on said front wall having interengagement portions thereon with the remainder of said front wall lying in a single plane, said interengagement portions comprising, a recessed receiving portion and a lug insert portion in spaced aligned horizontal relation to one another, said recessed receiving portion extending inwardly from the planar surface of said front wall and extending into said first side wall adjacent said front wall, said recessed receiving portion having longitudinally contoured tapered base and inner top surfaces, wherein said tapered base includes a lower lip portion extending inwardly from said planar surface of said front wall and said inner top surface includes an upper lip portion extending inwardly from said planar surface of said front wall, said lug insert portion having longitudinally contoured upper and lower engagement surfaces for co-lateral registration within said upper and lower lip portions of the other identical bottle container, and an outside engagement side surface extending in the same plane as said second side wall and an inner engagement side surface being planar and extending outwardly at an angle greater than ninety degrees from said flat planar surface of said front wall, said recessed receiving portion having a planar end inner wall extending inwardly at an angle greater than ninety degrees from said planar surface of said front wall for registration with the corresponding angularly disposed inner engagement side surface of said lug insert of an identical bottle container, such that said outside engagement side surface of said lug insert portion is positioned in the same plane as said first side wall of an identical bottle container to provide visual confirmation of said lug insert portion positioned within said recessed receiving portion of an identical bottle container when viewed from one of said first side and said second side of each container.

5. The modular molded bottle of claim 4 wherein said recessed receiving portion has a wall surface extending from said end inner wall outwardly from an adjacent adjoining integral wall and is of a divergent planar surface of reduced dimensional area.

6. The modular molded bottle of claim 4 wherein said recessed receiving portion comprises an inner back wall surface extending between said base and inner top surfaces, wherein said base and inner top surfaces and said inner back wall surface of said recessed receiving portion intersect the plane of said first side wall.

7. The modular molded bottle container set forth in claim 6 wherein said lug insert portion comprises a front surface extending between said upper and lower engagement surfaces, said front surface of said male lug portion is of a known surface dimension less than that of said inner back wall surface of said female recess portion.

8. The modular molded bottle of claim 5 wherein said base and inner top surfaces and said wall surface extending from said inner back wall surface of said recessed receiving portion intersect the plane of said first side wall.

9. A modular molded bottle container comprising,

a top and bottom and a plurality of walls therebetween,

said plurality of walls comprising a front wall having interengagement portions thereon for locking with identical interengagement portions of a second identical container,

said interengagement portions comprising a male portion and a female portion, said male portion extending from said front wall and having an outside surface extending in the same plane as a first side wall of said container adjacent said front wall, and said female portion extending into said front wall and further extending into a second side wall of said container that is adjacent said front wall and opposite said first side wall, said male portion configured to lock with a female portion of a second identical container, and said female portion configured to lock with a male portion of the second identical container,

said male portion having contoured surfaces,

said female portion having contoured surfaces that coincide with said contoured surfaces of said of said male portion of a second identical container when said container is locked with the second identical container,

said contoured surfaces of said female portion comprising an inner end wall that extends inwardly into said front wall at an angle greater than ninety degrees,

said contoured surfaces of said male portion comprising a vertical inside surface that extends outwardly from said front wall at an angle greater than ninety degrees, and

wherein when said container is adapted to be locked with a second identical container, the following condition is met: said male portion vertical inside side surface abuts said female portion inner end wall and said vertical outside surface of said male portion is positioned in the same plane as said second side wall of the second identical container to provide visual confirmation of said male portion positioned within said female portion when viewed from one of said first side wall and a second side wall of said container.
