The present invention has been made to solve the above-mentioned conventional problems, and an object thereof is to provide an opening / closing device that fits tightly on the lid of a drum can and can be opened and closed smoothly.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention is a lid opening / closing device for opening and closing a lid of a drum can, which has a concave portion on the upper surface and forms a protrusion in the concave portion, and includes a handle portion and a fitting portion. A plurality of fitting portions are provided inside and outside the concentric circles corresponding to the recesses of the lid having different diameters, and each fitting portion has a notch portion that engages with a protrusion of the recess of the lid. Is characterized by. The lid opening / closing device for a drum according to claim 2 is characterized in that the notches of the fitting portion are provided at positions corresponding to each other inside and outside the concentric circle. A lid opening / closing device for a drum according to claim 3 is characterized in that a plurality of cut portions of the fitting portion are provided.

[0005]

[Action]

 In the present invention, as shown in the figure, the notch portion provided in the fitting portion is inserted at the position where it is fitted into the protruding piece provided in the concave portion. As a result, the lid can be rotated with the fitting portion firmly fitted in the recess, and the lid can be smoothly opened and closed.

[0006]

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view showing an embodiment of a device for opening and closing a lid of a drum according to the present invention.

According to this embodiment, the lid opening / closing device for a drum can is composed of a handle portion 10 and a fitting portion 20. The diameter of the fitting portion 20 is formed so that it can be easily attached and detached in the recess 51 of the lid 50. That is, the inner diameter of the recess 51 corresponds to the outer diameter of the fitting portion 20. As a result, when the fitting portion 20 is fitted in the recess 51, a state in which there is no looseness between the fitting portion 20 and the recess 51 can be maintained. The fitting portion 20 is formed in a cylindrical shape with one end opened, and the other end is connected to the handle portion 10.

Further, in this embodiment, a plurality of large and small fitting portions 20 having different diameters are provided concentrically so as to correspond to the sizes of the lid 50 having different diameters of the concave portions 51. At present, two types of sizes of the lid 50 of the drum can are provided, and in this embodiment, two types of fitting portions 20 adapted to the diameters of the two types of the lid 50 are provided. As a result, the lids 50 having different sizes can be opened and closed with one device.

Further, a cutout portion 21 that engages with a protrusion 52 of the recess 51 is provided at the lower end of the fitting portion 20. The notch 21 is formed to have a width such that the protruding piece 52 fits as shown in FIG. 4 when the fitting portion 20 is fitted in the recess 51. As a result, when the fitting portion 20 is turned, the notch 21 is caught by the projecting piece 52, and the lid 50 can be turned. Moreover, you may provide this notch part 21 with two or more. If a plurality of cutouts 21 are provided, alignment with the projecting piece 52 can be easily performed. Further, as shown in FIG. 2, it is also possible to provide four notches 21 on the inside and eight notches 21 on the outside so that the notches 21 are connected to each other in the radial direction. With this configuration, the fitting portion 20 can be fitted even in the case of the lid having the protruding piece 53 connected in the radial direction as shown in FIG.

The handle portion 10 has a T-shaped bar and is connected to the fitting portion 20. This allows the handle portion 20 to be firmly gripped with both hands. The handle portion 10 may be detachable from the fitting portion 20. In the above embodiment, the plurality of fitting portions 20 are provided on the concentric circles, but the handle portion 10 may be provided on the opposite side as the opposite. Further, the number of the fitting portions 20 is not limited to two and may be three or more.

[0011]

[Effect of the device]

 As described above, the device for opening and closing the lid of the drum according to the present invention comprises the handle portion and the fitting portion, and a plurality of fitting portions are provided inside and outside the concentric circles corresponding to the concave portions of the lid having different diameters. When the lid is opened and closed by having the notch that engages with the protrusion of the concave portion of the lid, the fitting portion fits into the concave portion of the lid and fits loosely. The lid can be opened and closed smoothly without leaving. Also, since the fitting parts are provided on the inside and outside of the concentric circle, it is possible to open and close lids of different sizes with one opening and closing device, so there is no need to prepare multiple devices according to the large number of lids. Become. According to the present invention of claim 2, the positions of the notches provided in the plurality of fitting portions provided inside and outside the concentric circle are made to correspond to each other, so that opening and closing of the lid conventionally provided having different protruding piece shapes is performed. Can be done with one opening and closing device. According to the present invention of claim 3, since the plurality of notches provided in the fitting portion are provided, it is possible to easily align the position with the protrusion of the lid, so that the lid opening / closing device can be smoothly fitted into the lid. it can.
