Claims (5)

1. It comprises a cap body that is attached to the container body and a lid that is screwed onto the cap body, The cap body has a mounting portion that is attached to the mouth of the container body, a locking plate portion that extends radially from the lower outer edge of the mounting portion and has a projection erected on its upper surface , and a display portion formed on the locking plate portion . The lid has a screw cap that is screwed onto the cap body, a flange-shaped sealing portion connected to the lower outer circumference of the screw cap via a breakable weakening connecting piece, and a guide opening that is opened in the sealing portion and guides the projection. The dispensing cap is characterized in that, when the lid is opened, the locking plate portion has a projection that restricts the rotation of the sealing portion, and the display portion can be seen through the guide opening of the sealing portion, thereby confirming that the lid has been opened .
2. The locking plate portion has a display portion formed near the projection portion. The dispensing cap according to claim 1, characterized in that the guide opening has a locking opening that locks a projection by a locking projection formed in the radial direction, and a display opening adjacent to the locking opening and the locking projection, allowing the display to be seen.
3. The dispensing cap according to claim 1 or 2, characterized in that the locking plate portion has a connecting portion extending radially from the lower end of the mounting portion, a flange portion formed circumferentially from the connecting portion toward an adjacent connecting portion, and a severable break portion formed at the connection point between the flange portion and the connecting portion.
4. The cap body has a dispensing tube for pouring out the contents. The dispensing cap according to claim 1 or 2, characterized in that the dispensing cylinder has a transition stopper body connected to the inner circumferential surface via a thin-walled weakened portion, which engages with the screw cap and is removed when the lid is opened.
5. The cap body has a dispensing tube for pouring out the contents. The dispensing cap according to claim 3, characterized in that the dispensing cylinder has a transition stopper body connected to the inner circumferential surface via a thin-walled weakened portion, which engages with the screw cap and is removed when the lid is opened.

Description

This invention relates to a dispensing cap comprising a cap body attached to the mouth of a container body and a lid that is screwed onto the cap body. More particularly, it relates to a dispensing cap that allows the open state to be easily confirmed by rotating the lid in the opening direction. A conventional dispensing cap is known for its ability to hold dressings, condiments, and other food products. It features a sealed container body that remains airtight until opened. The lid, which screws onto the cap body, is rotated in the opening direction to remove a transition stopper from the cap body. The removed transition stopper is then held in place by the lid's locking mechanism, allowing for opening. Furthermore, the cap body has an opening confirmation section on its outer circumference, and the lid has a sealing band connected to its lower end via a breakable weakening connecting piece. The sealing band has an opening indicator visible from the opening confirmation section of the cap body when the lid is opened, allowing for visual confirmation of the opening status. (See, for example, Patent Document 1.) Japanese Patent Publication No. 2020-196532 This figure shows an embodiment of the present invention, a dispensing cap, attached to the container body; (a) is a top view, and (b) is a partial cross-sectional view.This figure shows the cap body of a dispensing cap, which is an embodiment of the present invention, with (a) being a top view and (b) being a side view.This figure shows the cap body of a dispensing cap, which is an embodiment of the present invention, with (a) being a side cross-sectional view and (b) being a bottom view.This figure shows the lid of a dispensing cap, which is an embodiment of the present invention, with (a) being a top view and (b) being a side view.This figure shows the lid of a dispensing cap, which is an embodiment of the present invention, with (a) being a side cross-sectional view and (b) being a bottom view.Figure 1(a) shows the state of opening the dispensing cap, with (a) being the set position, (b) being the start of opening, and (c) being an explanatory diagram just before the sealing part is broken from the lid. Next, the dispensing cap of the present invention will be described with reference to the drawings showing an embodiment of the dispensing cap, which comprises a cap body having a transition stopper. The dispensing cap of the present invention is suitable for use with containers of food, beverages, and condiments that require maintaining a sealed state before use. By simply rotating the lid in the opening direction, the sealing portion, detached from the lid, is securely locked to the cap body. This allows the indicator portion of the cap body to be visible through the indicator opening of the sealing portion, making it immediately clear whether the cap is open.
