Also disclosed are methods using the modular container systems and methods of storing substances in containers. The containers have a container base and a container cap and provide for child-resistant containers. A user can releasably remove the container cap from container base with a squeeze and lift sequence. For example, the user squeezes opposite sides of the container base, which releases a locking mechanism and allows for removal of the cap by lifting or pulling the container cap off from the container base. The components of the modular container system are modular and stackable. The modular system allow for organized, efficient, accessible and storage of the child-resistant containers. The modular container system also allows for easy counting, sorting and processing of the containers. ## Claims ### Claim 1 A child-resistant container comprising: a container base comprising a closed bottom end, an open top end, a radially-extending flange disposed on an outer surface of the container base, a first cap engagement element, and a second cap engagement element; wherein the first and second cap engagement elements are disposed on the outer surface of the container base, opposite each other, and between the open top end and the flange; and a container cap comprising one or more base engagement elements on an interior surface of the container cap, wherein each of the one or more base engagement elements are configured to engage and reversibly couple to the first and second cap engagement elements of the container base; wherein each of the one or more the base engagement elements of the container cap comprises an upper row of ridges and a lower row of ridges, and wherein the upper row and the lower row of ridges are configured to engage with the radially-extending flange, the first cap engagement element, the second cap engagement element, or a combination thereof; and wherein the first and second cap engagement elements of the container base each comprise: a raised surface to receive and engage with the base engagement element, wherein the raised surface is substantially parallel to the flange; a plurality of ridges disposed between the raised surface and the flange; and at least one groove between the plurality of ridges, wherein the at least one groove is configured to receive a ridge from the lower row of ridges. ### Claim 2 (depends on 1) The child-resistant container of claim 1, wherein engagement of the container base with the container cap enables the one or more base engagement elements to lockably secure with the first and second cap engagement elements to substantially provide a child resistant container when in a closed configuration. ### Claim 3 (depends on 2) The child-resistant container of claim 2, wherein the container base further comprises one or more anti-rotation locks symmetrically disposed on the outer surface radially between the first cap engagement element and the second cap engagement element. ### Claim 4 (depends on 3) The child-resistant container of claim 3, further comprising a grip marking disposed on the outer surface just below the radial flange on the same side of the cap engagement elements of the container base. ### Claim 5 (depends on 3) The child-resistant container of claim 3, wherein the container cap comprises four base engagement elements. ### Claim 6 (depends on 1) The child-resistant container of claim 1, wherein the container cap further comprises an elevated portion at a top end of the cap; and wherein the container base further comprises a receiving portion defined by a recessed floor of the base; wherein the elevated portion of the cap is adapted to engage the receiving portion of the container base so the child-resistant container can stack on another child-resistant container. ### Claim 7 (depends on 6) The child-resistant container of claim 6, wherein the receiving portion comprises a plurality of stacking elements disposed along an outer edge of the receiving portion. ### Claim 8 (depends on 1) The child-resistant container of claim 1, wherein the container base, the container cap or both comprise a polymer. ### Claim 9 (depends on 8) The child-resistant container of claim 8, wherein the polymer comprises polypropylene, polypropylene copolymer, ultra-clarified polypropylene, colored polypropylene, PET, PETE, polycarbonate, polystyrene, or a combination thereof. ### Claim 10 (depends on 8) The child-resistant container of claim 8, wherein the container cap further comprises an annular sealing ring positioned on an inner surface of the top end of the cap. ### Claim 11 (depends on 10) The child-resistant container of claim 10, wherein the container is substantially air-tight, liquid-tight, light resistant, temperature resistant, moisture resistant, bacterial resistant, tamper resistant, or a combination thereof. ### Claim 12 A method of applying a child-resistant closure on a container comprising: providing a child-resistant container comprising a container base and a container cap; wherein the container base comprises a closed bottom end, an open top end, a radially-extending flange disposed on an outer surface of the container base, a first cap engagement element, and a second cap engagement element, wherein the first and second cap engagement elements are disposed on the outer surface of the container base, opposite each other, and between the open top end and the flange; wherein the container cap comprises one or more base engagement elements on an interior surface of the cap, each of the one or more base engagement elements are configured to engage and reversibly couple to the at least one cap engagement element of the base; sliding the container cap over the open end of the container base, wherein the first and second cap engagement elements engage with and couple to the one or more base engagement elements, wherein: (1) each of the one or more base engagement elements of the container cap comprises an upper row of ridges and a lower row of ridges, and wherein the upper row and the lower row of ridges are configured to engage with the radially-extending flange, the first cap engagement element, the second cap engagement element, or a combination thereof, and (2) the first and second cap engagement elements of the container base each comprise: a raised surface to receive and engage with the base engagement element, wherein the raised surface is substantially parallel to the flange; a plurality of ridges disposed between the raised surface and the flange; and at least one groove between the plurality of ridges, wherein the at least one groove is configured to receive a ridge from the lower row of ridges. ### Claim 13 (depends on 12) The method of claim 12, wherein sliding the container cap over the open end of the container base enables the lower row of ridges to slide over and couple with the raised surface of the cap engagement element, and wherein a ridge from the lower row of ridges is received within the at least one groove on the container base. ### Claim 14 (depends on 13) The method of claim 13, further comprising removing the container cap by simultaneously applying about 2 to about 6 pounds of external compression force to opposite sides of the container base and pulling the container cap off of the container base.
