FIG. 4 is a perspective view of the lid body viewed from below, FIG. 5 is a partial perspective view of the L-shaped groove viewed from the inside of the lid body, and FIG. 6 is an L-shape. FIG. 7 is a partial perspective view of the pan body provided with a locking pin at the upper part of the inner surface of the pan body.

  First, FIG. 1 shows a pan 1 as an embodiment of the present invention. This pan 1 has a pan body 2 having an upper surface opened and a pair of handles 5 and 5 provided on an outer surface, and the pan. The lid 4 is detachably mounted on the upper surface of the main body 2 and closes the opening.

  As shown in FIGS. 2 and 7, the pan body 2 is formed, for example, in a bottomed cylindrical body whose upper portion is opened in a stainless steel plate or the like, and a pair of heat-resistant clothing handles 5 and 5 are provided on the outer periphery. A pair of locking pins 8a and 8b having a flange F formed at the tip are opposed to and project inward on the inner surface near the opening edge 2a of the pan body 2 corresponding to both handles 5 and 5. ing.

  As shown in FIG. 1, the lid 4 has a plan view, oval knob 6 attached to the center of the dome-shaped top plate, and the outer periphery of the lid 4 has an arcuate cross section outward. A cylindrical skirt portion 4a that forms the bulging portion 4b and extends vertically downward with a diameter slightly smaller than the diameter of the bulging portion 4b is formed below the arc portion so as to be insertable into the inner surface of the opening of the pan body 2.

  As shown in FIGS. 3 and 4, the top plate of the lid 4 is made of hot water or juice by tilting the pan 1 with the lid 4 closed after the noodles and vegetables are boiled. A large number of hot water cut holes h and H for discharging are disposed at symmetrical positions around the knob 6, and the large number of hot water cut holes h and H are attached to the inner surface of the top plate of the lid 4. Necessary areas can be opened and closed by turning the shielding plates 12a and 12b, and the shielding plates 12a and 12b are connected to the operation tool 7 rotatably supported around the knob 6 at the central portion. Yes.

  Furthermore, a pair of L-shaped locking grooves 10a and 10b are formed in the cylindrical skirt portion 4a of the lid body 4 at substantially target positions on both outer sides with the center of the lid body 4 interposed therebetween. The stop grooves 10 a and 10 b are provided so as to be able to be fitted with locking pins 8 a and 8 b protruding from the inner surface of the pan body 2.

  Specifically, as shown in FIGS. 5 and 6, the L-shaped locking grooves 10a and 10b are connected to the vertical cut portion 14a formed from the lower end edge of the cylindrical skirt portion 4a and the vertical cut portion 14a. It consists of a horizontal cut portion 14b facing in the same direction of rotation, and the inside of these locking grooves 10a, 10b is formed of a stainless steel plate having spring properties lined on the inner side surface of the cylindrical skirt portion 4a by spot welding or the like. Each of them is covered with a rectangular presser plate 16.

  The presser plate 16 is press-molded so that an L-shaped protruding portion 17 protrudes toward the inner side of the cylindrical skirt portion 4a corresponding to the locking grooves 10a and 10b. The flanges F of the locking pins 8a and 8b have a width capable of moving inside.

  A pair of elongated holes 18a and 18b are formed in the L-shaped projecting portion 17 in the vicinity of the rear end corresponding to the horizontal cut portion 14b of the locking grooves 10a and 10b, and are sandwiched between the elongated holes 18a and 18b. Thus, a spherical mountain-shaped protrusion 20 serving as a movement blocking body is formed to protrude.

  Further, the L-shaped locking grooves 10a and 10b formed in the cylindrical skirt portion 4a are narrower than the groove width of the L-shaped projecting portion 17 of the presser plate 16, and all are small diameter shaft portions P of the locking pins 8a and 8b. Is formed with a cut width that can pass through.

  Next, the opening / closing operation of the lid 4 will be described below.

  First, when closing the opening of the pan body 2 with the lid 4, when inserting the cylindrical skirt portion 4 a of the lid body 4 into the opening of the pan body 2, a pair of L formed on the skirt portion 4 a is formed. The insertion openings of the vertical cut portions 14a of the letter-shaped locking grooves 10a and 10b are lowered corresponding to the locking pins 8a and 8b on the inner surface of the pan body 2.

  As shown in FIG. 6, the size of the insertion opening 17a at the lower end of the vertical cut portion 14a has a width for receiving the flange F of both the locking pins 8a and 8b. When the bulging portion 4b at the upper end of the portion 4a abuts against the opening edge 2a of the pan body 2, both the locking pins 8a and 8b are positioned at a substantially middle portion of the groove width of the horizontal cut portion 14b.

  Therefore, when the lid 4 is rotated clockwise as viewed from above, the horizontal cut portion 14b moves in the rotational direction until it is guided by the small diameter shaft portion P of the locking pins 8a and 8b and hits the rear end. Immediately before the locking pins 8a and 8b abut against the rear end of the horizontal cut portion 14b, the front end surface of the flange F of the locking pins 8a and 8b comes into contact with the chevron-shaped projecting portion 20, thereby generating resistance in the rotational direction.

  When the lid 4 is further rotated against this resistance, the front end surface of the flange F applies a pressing force to the mountain-shaped protrusion 20 and the horizontal movement of the presser plate 16 due to the notch effect of the pair of elongated holes 18a and 18b. The portion corresponding to the cut portion 14b is elastically deformed inward, the front end surface of the flange F gets over the projection portion 20, stops in contact with the rear end of the horizontal cut portion 14b, and prevents the lid 4 from freely moving. Can do.

  In this way, since the protruding portion 20 can move over the protruding portion 20 while elastically deforming the presser plate 16 having a spring property, the closed position of the lid 4 can be taken. Not only prevents the lid 4 from being pushed up by the broth, but also if the pan body 2 vibrates or the lid 4 comes in contact with something, the lid 4 is moved by the protrusion 20. It is blocked and can completely prevent spilling.

  Further, the rectangular presser plate 16 is attached so as to cover one side of the L-shaped groove formed by the vertical cut portion 14a and the horizontal cut portion 14b, so that the inside of the pan body 2 is communicated with the outside. It can be cut off and can be easily elastically deformed by forming a pair of elongated holes 18a and 18b on both sides of the protrusion 20 of the protrusion 17 by notching.

  Furthermore, by forming the mountain-shaped protrusion 20 in a spherical shape, it is possible to reduce the frictional resistance when the tip surfaces of the locking pins 8a and 8b get over the protrusion 20. In the above-described embodiment, the example in which the L-shaped locking grooves 10a and 10b are arranged on both outer surfaces across the center of the lid 4 has been described. However, these L-shaped locking grooves are divided into two. Not limited to this, it is also possible to provide a predetermined number of the pan body 2 or the outer edge portion of the lid body 4 at equal intervals, and the degree of closure of the lid body 4 can be evenly increased with respect to the opening.

  As mentioned above, although the Example of this invention has been described with reference to the drawings, a pair of L-shaped locking grooves formed on both outer side surfaces of the lid body are provided on the inner surface upper portion of the pan body, and on both outer side surfaces of the lid body. A configuration in which a locking pin corresponding to the L-shaped locking groove is protruded is also possible, and the specific configuration is not limited to these embodiments, and there are changes and additions within the scope not departing from the gist of the present invention. Is included in the present invention.
