Modular mid-section detachment system for drinkware bottles and containers

A modular container system comprising:

• a base vessel member having a closed first end configured to hold a fluid, and an open second end configured for removably coupling to a body vessel member;
• one or more body vessel members having a first end for removably coupling to the base vessel member, and a second end for removably coupling to additional body vessel members and a lid vessel member, and
• the lid vessel member having a first end configured to couple to the body vessel member and a second end configured for opening and closing the modular container system;
• wherein the base, body, and lid vessel members are removably coupled to one another through a modular detachment interface;
• wherein the modular detachment interface includes an internal detachment system having a threaded sealing mechanism configured to maintain a leak-proof connection between one or more vessel portions, and an external detachment system having a snap-fit sealing mechanism configured to maintain a leak-proof connection between one or more vessel portions;
• and
• wherein at least one vessel portion includes an accessory insert, and wherein the accessory insert includes one or more curved surfaces that extend along a longitudinal axis of said vessel portion.

A modular container system comprising:

• a plurality of vessel portions, including at least a first vessel portion and a second vessel portion, each having a modular detachment interface;
• wherein the first and second vessel portions are detachably couplable via said modular detachment interface;
• wherein the modular detachment interface includes an internal coupling system and an external coupling system;
• wherein the internal coupling system of the modular detachment interface includes a rotatable securement member;
• wherein the external coupling system of the modular detachment interface includes a snap securement member;
• wherein the system further comprises an external fastener positioned between the first vessel and the second vessel to secure them together;
• and
• wherein the external fastener is configured to receive and at least partially conceal a portion of the first vessel and the second vessel;
• wherein at least one vessel portion includes a modular insert interface configured to removably receive an accessory member.
