2. Description of the Related Art Since seasoning containers used in cooking and the like are often used while holding a frying pan or a pan with one hand or handling food, the cap is opened with a thumb while holding it functionally with one hand. There is a need for a so-called one-touch operation that can be used with one hand as it is and can be returned to the original position after use by closing the cap with the thumb or the like. Conventionally, various caps have been developed and used in response to the demand, but many of them are generally composed of three pieces, and some use metal springs to realize one-touch operation. The smaller number of parts is advantageous in terms of cost because the number of dies is smaller, and the smaller number of parts reduces the assembly burden. A material made of a foreign material in which a plastic cap body and a metal part are combined has a problem that it must be disassembled and discarded at the time of disposal. In response to such demands, the applicant has previously developed a two-piece cap made of plastic material and has received a utility model registration (Registration No. 2060010). This is of the form shown in FIG. 5 and comprises a cap body 2 having a spout hole 21 in the top part, and a lid 3 pivotally supported by the cap body 2 and covering the spout hole 21 so as to be openable and closable. By pushing down the rear plate portion 32 located rearward from the pivot portion of the lid 3,

I want to. The state of (II) when the lid 3 is in the middle position is shown by a broken line.

Therefore, in the present invention, the front plate 31 is also provided with a rotation shaft 37 at a position away from the thin portion 36 by a predetermined distance R2, and the position of the rotation shaft 37 when the lid 3 is closed is determined. The cap body 2 is provided with an elongated hole 27 extending in the front-rear direction by connecting a position of the rotation shaft 37 in the fully opened state to guide the rotation shaft 37. With this mechanism, when the rear plate portion 32 of the lid body 3 is pressed and rotated counterclockwise in the drawing, the thin portion 36 is moved on the circumference in the rearward and downward direction.
Since the front plate 31 is connected to 36, the front plate 31 is also pulled in that direction. However, the front plate 31 has a thin wall 36
A rotation shaft 37 is provided at a position separated by a predetermined distance R2 from
Since the rotating shaft 37 is guided by the elongated hole 27 provided in the cap body 2, the front plate portion 31 is rotated clockwise by the hinge action of the thin portion 36 while allowing the displacement in the front-rear direction, and is fully opened. Displace to the state. The closing operation is performed by pressing the end of the rear plate 32 of the lid 3 inclined by the α angle, the rear plate 32 rotates clockwise in the drawing, and the thin portion 36 moves upward on the circumference. Since the front plate 31 is connected to the thin portion 36, the front plate 31 is also pushed up in that direction. However, a rotating shaft 37 is provided on the front plate portion 31 at a position away from the thin portion 36 by a predetermined distance R2, and the rotating shaft 37 is guided by the elongated hole 27 provided in the cap body 2, so that The front plate 31 is rotated counterclockwise by the hinge action of the thin portion 36 to displace it to a closed state while allowing the displacement in the direction. Thus, the mechanism of the present invention is a mechanism that can easily open and close the lid by a one-touch operation of pressing and rotating the rear plate portion 32. Moreover, although it is made of a two-piece plastic member,
In the fully opened state, the opening angle of 90 degrees is ensured with respect to the ceiling having the squirt hole 21, so that the lid does not obstruct the swaying unlike the conventional one.
