  The containers of Patent Document 1 and Patent Document 2 above are built in such a manner that a small container is easy to use in the mouth / neck part of the container body or a part of the cap, but in recent years, products are distributed from the viewpoint of safety. In order to meet these requirements, it was necessary to cover the containers of both documents with a shrink film or the like.

  An object of the present invention is to provide a combination container in which an existing portion container can be easily and safely incorporated into a main container and can be easily taken out.

The first means is
The coupling tube 20 that links potions container 6 to the top of the cap 4 with main container 2, together with fitting the potion container 6 in a closed-top of the cylindrical wall in the upper, a cylindrical wall lower end, to the main container portion of the cap downward A virgin ring 34 that is fixed and separable from the other part of the connecting cylinder via the breaking line 32 is formed, and at the center of the top wall of the connecting cylinder 20 is an elastic dome wall 26, the breaking line 32 is broken. The portion container 6 can be taken out of the connecting cylinder 20 by the downward inversion of the elastic dome wall 26 later.

  The “main container” is a container for storing food and drink and the like, and a cap can be fitted to the outer surface of the container body neck.

  The “portion container” is a small container for mainly containing additives such as milk and seasonings. This small container can be an existing portion container in which a sealing lid is attached to the upper end surface of a cup-shaped main body with a top.

The “connecting cylinder” also functions as a cover cylinder that covers the cap portion of the main container and the portion container, and seals the upper portion of the main container and the portion container . The outer peripheral surface of the portion container is fitted (fitted) into the cylinder wall of the connecting cylinder . Furthermore , you may engage the collar part of a portion container with the engagement rib attached to the appropriate place of the inner surface of a connection cylinder. It should be noted that fixing the lower end portion of the connecting cylinder may be performed so that it cannot be pulled out upward, and this lower end portion may be engaged with an engaging means attached to the main container portion below the cap.

  The “elastic dome wall” is formed so that it can be elastically reversed and restored between the dome shape and the inverted dome shape, and the elastic force and the reversal width that can push the potion container downward by elastic reversal downward ( The height of the dome center portion in the dome shape and the reverse dome shape) is provided.

    The second means includes the first means, and the portion container 6 has a collar portion 10 attached to the upper end of the cup-shaped main body 8, and a seal lid 14 is attached to the upper surface of the collar portion. The potion container 6 is formed so that it can be accommodated along the upper surface of the cap 4 by fitting the portion container 6 to the upper part of the connecting cylinder 20 in an inverted state.
