Abstract

A hinge cap having a preferable appearance irrespective of opening and closing of a cap cover, to facilitate a one-hand opening manipulation, and to prevent cost increase. In the hinge cap, a cap main body has a top plate, and most of a manipulation body for transmitting pushing force for opening the cap to the inside surface of an opening/closing hinge is covered even in a state that a cap cover is opened. Therefore, the hinge cap appearance is improved and the movement of the manipulation body does not deteriorate because the contents hardly leak into the movable portion of the manipulation body.

Independent Claims | See all claims (18)

  1. 1. A hinge cap comprising: a cap main body; a cap cover configured to cover a top portion of the cap main body and connected to the cap main body by an opening/closing hinge; and a manipulation body incorporated in the cap main body to be used for a manipulation of opening the cap cover; the cap main body comprising: a top plate formed with an output mouth; an outer circumferential wall provided along an outer circumference of the top plate; and an inner circumferential wall extending from the top plate and integrally formed with the outer circumferential wall, the manipulation body comprising: a push button portion exposed to outside penetrating through the outer circumferential wall of the cap main body; and a pushing end for causing the cap cover to open when the push button portion is pushed, wherein a portion of the manipulation body is accommodated under the top plate between the outer circumferential wall and the inner circumferential wall, and the top plate is configured to cover a main part of the manipulation body even in a state that the cap cover is opened.
  2. 2. A hinge cap comprising: a cap main body; a cap cover configured to cover a top portion of the cap main body and connected to the cap main body by an opening/closing hinge; and a manipulation body incorporated in the cap main body to be used for a manipulation of opening the cap cover; the can main body comprising: a top plate formed with an output mouth; an outer circumferential wall provided along an outer circumference of the top plate; and an inner circumferential wall extending from the top plate, provided inside the outer circumferential wall and integrally formed therewith; the manipulation body comprising: a pushing end; a push button portion exposed to outside penetrating through the outer circumferential wall of the cap main body; and a transmission rod connecting the pushing end and the push button portion to cause the pushing end to push the opening/closing hinge from inside when the push button portion is pushed; the transmission rod being made of a resilient material to store a force for pushing the opening/closing hinge during a manipulation stroke from a position where the pushing end contacts the opening/closing hinge to a position where the push button portion is pushed thereafter by a prescribed length, the pushing end and the transmission rod of the manipulation body being accommodated under the top plate between the outer circumferential wall and the inner circumferential wall, the top plate being configured to cover a main part of the manipulation body even in a state that the can cover is opened.
  3. 7. A hinge cap comprising: a cap main body; a cap cover configured to cover a top portion of the cap main body and connected to the cap main body by an opening/closing hinge; and a manipulation body being incorporated in the cap main body to be used for a manipulation of opening the cap cover; the cap main body comprising: a top plate formed with an output mouth; an outer circumferential wall provided along an outer circumference of the top plate; and an inner circumferential wall extending from the top plate, provided inside the outer circumferential wall and integrally formed therewith; the manipulation body comprising: a push button portion exposed to outside penetrating through the outer circumferential wall of the cap main body; a pushing end disposed to be opposed to the opening/closing hinge from inside; and a transmission rod connecting the pushing end and the push button portion to cause the pushing end to push the opening/closing hinge and thereby cause opening action on the cap cover when the push button portion is pushed, wherein a portion of the manipulation body being accommodated under the top plate between the outer circumferential wall and the inner circumferential wall, the top plate is configured to cover a main part of the manipulation body even in a state that the cap cover is opened, and the transmission rod is made of a resilient material to store a force for pushing the opening/closing hinge during a manipulation stroke from a position where the pushing end contacts the opening/closing hinge to a position where the push button portion is pushed thereafter by a prescribed length.
