Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a lid opening/closing device for taking out contents such as powder or granules from an outlet provided on the top surface of a container.

(Prior Art) In this type of container, there is a device described in Utility Model Publication No. 51-38584, which opens and closes the lid of a dispensing hole provided on the top surface of the lid in conjunction with the rotation of the lid.

(Problems to be Solved by the Invention) The device described in the above-mentioned publication has a swinging hole 14 at a position close to the periphery of the top surface of the container, and a hinge 10 for raising and lowering the opening/closing lid 12 that opens and closes the opening hole 14 is rotatable. Lid 6
The opening/closing lid 12 is erected by the contact between the contact piece 13 provided near the hinge 10 and the one-side abutting portion 16 of the recess 15 formed on the container 2 side. Therefore, the distance between the contact piece 13 and the abutment part 16 is set such that the free movement section is as small as possible in order to make the opening operation advantageous, and the hinge relative to the swinging hole 14 is set so as to limit the amount of rotation of the rotating lid 2. The amount of rotation of the opening/closing lid 12 is reduced, and the contents from the shaking hole 14 are generally shaken out in a direction close to the periphery of the container 1, that is, in a radial direction, and the contents are shaken out in a radial direction perpendicular to the rotating direction of the opening/closing lid 12. Therefore, when the amount of rotation of the opening/closing lid 12 is limited as described above, there is a problem in that the distance between the dispensing hole 14 and the opening/closing lid 12 is not sufficient, causing trouble in dispensing the contents.

(Means for solving the problem) The present invention eliminates the inconveniences caused by the above conventional means,
It is designed to facilitate the removal of contents, with a top plate of a circular cylindrical inner lid that attaches to the mouth of the container, with an outlet deviated to one side from the center and an axis centered on the other side. An arc-shaped slot intersecting the arc and gradually curving inward at one end is provided, and one side edge is aligned approximately in the direction of rotation on the top plate of a cylindrical outer cover that is rotatably fitted to the inner cover. An opening/closing lid is formed of cut-out free pieces connected by bent edges, and a protruding piece is provided on the inner surface of the opening/closing lid protruding from the bent edge, and the protruding piece is inserted into the slot. It is formed along the side edges.

(Function) In the present invention, FIGS. 1 and 3 of the embodiment
When the outer cover 8 is rotated counterclockwise as shown by the arrow in FIG. 3 from the closed state shown in the figure, the protrusion 11 is pushed by the outer edge of the slot 7 and sequentially tilts inward. As the lid 10 is tilted, the lid 10 is bent and erected at the bent edge 9, and when the protruding piece reaches the other end of the slot 7, as shown at 11' in FIGS.
At a predetermined opening degree of 0, the lid becomes open as shown in FIG. 2, and at this time, the bending line 9 of the opening/closing lid 10 sandwiches the center 4 of the inner and outer lids as shown by the phantom lines in FIG. Therefore, the outlet 5 is opposite to the opening/closing lid 10.
It is located on the opening/closing direction line, and the outlet 5 and the bent line 9 are at the maximum distance position, and the upper surface of the outlet 5 is wide open, making it easy to take out the contents. If the protrusion 11 is rotated clockwise in the opposite direction to the direction of the arrow from this state, the opening/closing lid 10 will be pushed down by the inner edge of the slot 7, and the protrusion 11 will return to its original position at the end of the slot 7. When this happens, the opening/closing lid 10 is in the opening/closing state shown in the first figure.

(Example) Embodiments of the present invention will be described with reference to the drawings.

Reference numeral 1 denotes a container, to which a cylindrical inner lid 3 is fastened to its mouth 2 with, for example, screws or other means to prevent it from rotating unintentionally, and a cylindrical outer lid 8 can be freely rotated by overlapping the outer surface of the container. However, fit it in such a way that it cannot be pulled out.

As shown in FIG. 4, the top plate of the inner lid 3 has an outlet 5 opened on one side relative to the center 4, and the other side intersects an arc 6 with the center 4 as an axis, so that one end gradually connects to the center 4. An arcuate slot 7 is provided which curves inwardly.

Reference numeral 8 denotes an outer cover that is rotatably fitted to the inner cover 3, and the top plate of the outer cover 8 has a thin linear weakened line with one side edge substantially along the direction of rotation, as shown in FIG. An opening/closing lid 10 is provided which is made of a cut-out free piece connected by a bent edge 9 formed by, etc., and is undulated at the bent edge 9 to open and close the outlet 5.
A projecting piece 11 protruding to the inner surface was provided adjacent to the inner cover 3, and this was inserted into the slot 7 of the inner cover 3 so as to run along the side edge of the slot 7. Then, when the outer cover 8 is attached to the inner cover 3 and the protruding piece 11 of the outer cover 8 is positioned on one side of the arcuate side far from the center 4 of the slot 7 of the inner cover 3, the first As shown in the figure, the opening/closing lid 10 is made to fall down and close the outlet 5, and the outer lid 8 is rotated in the direction of the arrow in FIG.
When the opening/closing lid 10 is positioned at the end of the opening/closing lid 10, the opening/closing lid 10 is raised to open the outlet 5;
0 is arranged to face the outlet 5 with the center 4 in between, the outlet 5 and the opening/closing lid 10 are widely separated, and the outlet 5 is positioned on the line in the opening/closing direction of the opening/closing lid 10.

Although not shown, the inner lid 3 is designed so that when the protrusion 11 reaches both end positions of the slot 7 and the opening/closing lid 10 is in the open or closed state, the opening/closing lid 10 is automatically stopped at each position. It is optional to provide a locking function using a convex portion and a concave portion on the fitting surface between the outer cover 8 and the outer cover 8.

In the figure, reference numeral 12 denotes a thick wall portion that reinforces the slot 7.

(Effect of the invention) According to the present invention, by simply rotating the outer cover, as the protrusion protruding from the inner surface of the opening/closing cover moves, the protrusion can be pushed by the side edge of the arcuate hole. The opening/closing lid can be raised and lowered to open and close the outlet, and the operation is extremely simple.The opening/closing lid's undulating bent edge is a straight line approximately along the direction of rotation, and when the opening/closing lid is opened, the bent edge is Since the center of the rotating lid is sandwiched between the rotating lid and the opening to face the opening, the opening and the opening/closing lid are facing each other at the maximum distance, and the opening is located on the line in the opening/closing direction, so the contents can be dispensed from the opening. The opening/closing lid does not get in the way, making the shaking operation smooth, and the opening/closing of the opening/closing lid is done in one operation, which has the effect of simplifying handling.
