DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lid for a container capable of dispensing a predetermined amount of granular or powdery contents.

[0002]

2. Description of the Related Art A container lid is known in which a desiccant is held inside a threaded outer lid via a back lid, and a swing outlet is provided in an inner lid attached to the mouth of the container. (Japanese Utility Model Publication No. 57-4614).

[0003] Since this product has ventilation holes in the back lid and the inner lid that hold the desiccant, when the outer lid is closed, the contents can be hermetically sealed with the desiccant inside the outer lid. it can. On the other hand, since the outlet is formed on the upper surface of the inner lid, by removing the outer lid and opening the outlet, the contents can be divided into small portions and spouted. The inner lid is mounted so as to cover the mouth of the container, and two outlets are formed.
The two outlets are formed on the upper surface of the inner lid at symmetrical positions sandwiching the central ventilation hole.

Further, a desiccant is held on the inner surface side of the inner lid,
It is also known that one large outlet is formed on the upper surface of the inner lid (Japanese Utility Model Publication No. 58-22942), and since the outlet is large, the amount of one ejection is larger than the former. Suitable for use.

[0005]

According to the prior art, since all the outlets are formed on the upper surface of the inner lid, once the contents are ejected from the outlet, all of the contents are external. At the same time, and there is a problem that the amount of squirting cannot be finely adjusted at all. In other words, when the container is a medicine or the like, even if the final required amount is determined by weighing, if the amount of the container cannot be finely adjusted when the container is shaken, the container once shaken is shaken. Often it is necessary to return to the container via the outlet, which makes the whole operation extremely remarkable and complicated.

In view of the above-mentioned problems in the prior art, it is an object of the present invention to form the outlet from the bottom surface of the inner lid to the peripheral wall so that the amount of the outlet can be finely adjusted freely. It is an object of the present invention to provide a lid of a container that can only gently shake out the container.

[0007]

In order to achieve the above object, the present invention comprises a screwed outer lid mounted on the mouth of a container, and a bottomed cylindrical desiccant mounted inside the outer lid. It consists of a back cover for holding, and a bottomed cylindrical inner cover that is inserted upwards so as to be dropped into the mouth of the container, and the inner cover has a ventilation hole corresponding to the ventilation hole at the center of the bottom surface of the back cover. And a spout that opens from the bottom surface of the inner lid to the peripheral wall and has a sealing rib all around, and the rib of the spout is attached to the mouth of the container by attaching the outer lid to the body of the back lid. The gist of the present invention is that the entire length is tightly attached to the main body portion and the bottom surface of the back cover to seal the entire circumference of the swing outlet by housing the inside of the back cover.

[0008] In addition, the bottom of the inner lid can be cut out so as not to form a sharp corner at both ends, and the bottom of the inner lid can be cut out in an arc shape. The peripheral wall can be cut out parallel to the bottom surface of the inner lid.

The vent hole of the inner lid is provided with a sealing rib around the inner lid, and the rib of the vent hole is attached to the bottom of the back lid by attaching the outer lid to the mouth of the container. In addition, it is possible to seal around the ventilation hole of the inner lid.

[0010]

According to the structure of the present invention, the outlet is formed from the bottom surface of the inner lid to the peripheral wall which is inserted upward so as to be dropped into the mouth of the container. By properly tilting the container, a part of the object can be retained on the peripheral wall of the inner lid without directly falling to the outside. Therefore, the amount of stagnation on the peripheral wall of the inner lid in this way can be easily fine-adjusted by dropping only a part of the container to the outside. By being erected, it can be returned into the container via the outlet.
In addition, the ventilation holes formed corresponding to the back lid and the inner lid can exert a dehumidifying effect by the desiccant in the container, and the ribs of the outlet, when closing the outer lid, seal the outlet, The contents are prevented from leaking between the inner lid and the back lid.

[0012] In the case of the outlet having no sharp corners at both ends, there is no possibility that the granular contents are hung on both ends of the outlet.

When the bottom of the inner lid is cut out in an arc shape, it is easy to increase the opening area of the bottom.

[0013] The swing outlet, which cuts out the peripheral wall of the inner lid in parallel with the bottom surface, opens long with respect to the peripheral wall, so that the excess contents remaining on the peripheral wall can be easily returned to the container.

When the outer lid is closed, the ribs of the vent seal the vent through the back cover, thereby enhancing the moisture-proof effect of the container.
