Integrally formed attachment cap with lid opened by single push

Abstract

A thin attachment cap capable of simply taking out contents from a container containing drinking water, juice, powder or the like. In the attachment cap ( 30 ), by pressing down a pressing part ( 33 ) in the direction of an arrow ( 34 ) while a lid ( 31 ) is closed, the lid ( 31 ) rotates in the direction of an arrow ( 35 ) and an extraction port ( 37 ) is opened. When the pressing part ( 33 ) is completely pressed down, the lid ( 31 ) stands up approximately at the right angle with respect to a cap base ( 32 ). When the lid ( 31 ) stands up, the lid ( 31 ) is temporarily fixed, and a liquid or the like in the container can be smoothly taken out through the extraction port ( 37 ).

1 . An integrally formed attachment cap attached to a container in order to take out contents in the container and allowing its lid to be opened and closed by a single push, the integrally formed attachment cap comprising:
 a cap base having a pouring opening for taking out the contents, an attachment surface of the cap base being attached to the container;   a hinge section including a pushing operation section rotatably connected adjacently to one end of the cap base and a correction arm section formed spaced apart from and parallel to the pushing operation section; and   a lid body rotatably connected adjacently to the other end of the pushing operation section and the correction arm section and having a plug section for sealing the pouring opening,   wherein the cap base has a receiving region capable of receiving the pushing operation section on an upper surface of the cap base facing an attachment surface of the cap base; a bottom surface of the receiving region is formed lower than the surface on which the correction arm section abuts against the upper surface; and in a state in which the pouring opening is sealed by the plug section, when the pushing operation section is pushed out into the receiving region, the lid body rotates to release the plug section from the pouring opening.   
     
     
         2 . The integrally formed attachment cap according to  claim 1 , wherein the correction arm section is formed spaced apart from and parallel to both sides of the pushing operation section. 
     
     
         3 . The integrally formed attachment cap according to  claim 1 , wherein a sectional side of the correction arm section contacting the cap base is formed flared such that when a pushing operation is performed, the correction arm section always contacts a lower portion of the cap base, thereby preventing lifting upward. 
     
     
         4 . The integrally formed attachment cap according to  claim 1 , further comprising a cylindrical wall around the pouring opening. 
     
     
         5 . The integrally formed attachment cap according to  claim 1 , wherein the plug section has a protruding section fit into the pouring opening. 
     
     
         6 . The integrally formed attachment cap according to  claim 1 , further comprising a hook section for temporarily fixing the lid body to the cap base. 
     
     
         7 . The integrally formed attachment cap according to  claim 1 , wherein the attachment cap is integrally formed of a synthetic resin. 
     
     
         8 . The integrally formed attachment cap according to  claim 1 , wherein the cap base has an air vent for passing air into the container and the lid body has an air vent plug section for closing the air vent when the lid body is completely closed. 
     
     
         9 . The integrally formed attachment cap according to  claim 1 , wherein when the pushing operation section is pushed down into the receiving region by a pushing operation, an end section on a pushing operation section side in a bending section formed between the pushing operation section and the lid body contacts a wedge-shaped side surface in an upstanding section of the cap base from a bottom section in the receiving region, an end section on the lid body in the bending section is located on an upper surface of the upstanding section of the cap base, and thereby the lid body maintains a state of standing up on the upper surface of the cap base.
