PURPOSE: To make it possible to freely pour additives into a drink within a container according to a taste, by sealing the bottom and top of the container with an impermeable film to water and air which can be perforated and by fitting a small container for the additives filled with milk or syrup, etc., into an insertion-recess for the small container on a cap-form cover.

CONSTITUTION: This container for drinks comprises a small vessel 1 to enclose such additives as milk and syrup, etc., and a cap-form cover 6 which is fitted with the small vessel and applied to the container 10 for drinks. The small vessel 1 for additives is sealed with an impermeable film 2 to water and air, which can be performed, at the upper and bottom openings. The cap-form cover 6 applied to the container 10 with a drink 24 like coffee prevents dust and flies from intrusion and also the contents from spilling over. Persons, who want milk and/or syrup, fit the small vessel 1 into a insertion-recess 8 of the cap-form cover 6 and insert a straw 12 into the container through a laminated film 2 of the small vessel 1. In this way, milk and/or syrup of the small vessel can be poured into the container 10 for drinks.
