Description

  The present invention relates to a hinge cap comprising a cap body fixedly held at the mouth of a container and a lid connected to the cap body via a hinge, and in particular, a container filled with heated contents. The shower water sprayed to cool these containers and hinge caps after being fixed to and held in can effectively enter the gap between the cap body and the lid body and effectively avoid problems that remain. It is related with the hinge cap which can do.

  After filling the contents into the container, the hinge cap is stoppered and fixed and held at the mouth of the container. In the contents filling and stoppering process, for example, when the contents are food, the container is filled. In addition to the contents themselves, in order to sterilize the container and the hinge cap, the contents are heated and filled into the container. Then, when the contents are heated and filled, it is common to cool the entire container by spraying shower water on the outside of the container and the hinge cap (cooling step).

  By the way, in a container fitted with such a hinge cap, when the contents are poured out from the container and the contents poured out on the mating surface of the cap body and the lid are attached, the lid is closed. This residual content may scatter around. In order to deal with such a problem, a cap is formed on the upper surface of the cap body on the edge side, and the cap body is brought into contact with the lower surface of the edge side of the lid body when the cover body is changed to the closed posture. There is known a hinge cap that attempts to effectively prevent scattering of the residual contents by providing a gap between the lid and the lid (for example, see Patent Document 1).

  In the hinge cap provided with such a gap, shower water sprayed after filling the contents may enter the gap. And if this water remains, it will be unsanitary and the product value will be lost, so it will be necessary to remove it. The water that has entered the narrow gap is surely and easily removed. However, it is not easy to discharge by simple work, and there is still room for improvement in this respect.

  The problem of the present invention is to reliably prevent the trouble that shower water sprayed in the cooling process enters and remains in the gap between the cap body and the lid body by a simple operation. A hinge cap that can be used is proposed.

The present invention has a top wall that covers the mouth of a container, a cap body fixedly held in the mouth, and a ring that is slidably connected to the cap body via a hinge and stands up from the top wall A lid that removably locks the inner surface of the peripheral wall to the claw portion, and a pouring cylinder that stands up from the top wall in a closed posture of the lid, and a seal cylinder that hangs down from the top wall of the lid periphery in to a hinge cap you and form a circular space surrounded by the peripheral wall of the lid body,
The lid has an opening that penetrates the front and back and faces the annular space ,
The cap body is provided with a gap between the upper surface of the top wall and the lower surface of the peripheral wall in the closed posture of the lid,
It is a hinge cap characterized in that at least one cutout for communicating the opening and the gap is formed in the annular claw portion.

  Preferably, the gap is formed by at least one step portion provided on at least one side of the upper surface of the top wall and the lower surface of the peripheral wall and in contact with the other side.

A plurality of the stepped portions are provided at intervals along the edge of the top wall of the cap body or the edge of the peripheral wall of the lid,
The notch is preferably provided between the stepped portions.

  It is preferable that the openings are provided in series between the stepped portions and the notches.

An opening that penetrates through the front and back of the lid connected to the cap body via a hinge and faces the annular space is provided, and a gap is formed between the upper surface of the top wall of the cap body and the lower surface of the peripheral wall of the lid.
