Description

[Detailed description of the invention] This invention relates to a sterilizer lid that maintains sufficient strength and heat insulation properties.

Conventionally known sterilizer lids are made of a single thin plate, but this does not provide sufficient strength and also has poor insulation properties.

In particular, the pressure inside the sterilizer is quite high, so if the lid is not strong enough, it can be extremely dangerous.

In addition, the temperature inside the sterilizer becomes quite high, and if the lid also becomes hot at this time, there is a risk of burns when opening and closing the lid.

In order to eliminate the above-mentioned conventional drawbacks, this invention is such that the lid is composed of two pieces, an upper lid plate and an auxiliary lid plate.

This will be explained below with reference to the illustrated embodiment.

A sterilizer main body 1 of this embodiment is directly connected to a steam generator 2, and a nozzle 3 is made to protrude into the main body 1.

This sterilizer main body 1 has a main cover plate 5 inscribed in its opening edge 4, and the main cover plate 5 has the following shape.

That is, the main cover plate 5 is made of an elastic circular iron plate, and as shown in FIG.
It is curved in the direction perpendicular to the front, making it slightly elliptical when viewed from the front.

Of course, the diameter R of the main cover plate 5 is made slightly larger than the diameter of the opening edge 4, while the length in the short axis direction is shorter than the diameter of the opening edge 4 when viewed as an ellipse.

The leftover auxiliary lid plate 6 has a similar shape, one size smaller than the main lid plate 5, and is made of an elastic material.

One end of the bifurcated connecting member 1 is fixed to the center of the auxiliary lid plate 6 constructed as described above, and this connecting member I is further inserted through the main lid plate 5.

The relative relationship between the raincoat plates 5□ and 6 at this time is as follows.

That is, the curved surfaces of the raincoat plates 5 and 6 are opposed to each other, and the long axes of the raincoat plates 5 and 6 when viewed as ellipsoids are perpendicular to each other.

A heat insulating material 8 having a certain degree of elasticity is interposed between these raincoat plates.

The other end of the connecting member 1 that holds the raincoat plates 5 and 6 as described above passes through the elongated hole 10 of the arm member 9, which has a length that crosses between the opening edges 4, and is attached to the end thereof. A handle 11 is rotatably attached.

This handle 110 is attached to the cam member 1 of this invention.
2.

That is, the cam member 12, depending on its rotational position,
The distances from the center of rotation 13 to the contact surface of the arm member are made different.

In addition, the reference numeral 14 in the figure is a leaf spring, which connects the main cover plate 5 and the arm member 9.
This applies force in the direction that separates the two.

One end of the arm member 9 constructed as described above is attached to the sterilizer main body 1 in the following manner.

That is, the reinforcing member 15 fixed to one end of the arm member 9
is rotatably fixed to one end of a dogleg-shaped link member 16.

The other end of this ring member 16 is attached to the main body 1.
It is rotatably fixed to the free end of a hinge plate 17 fixed to.

Note that the arm member 9 is made to coincide with the long axis when the main cover plate 5 is viewed as an ellipse.

However, in order to insert the main cover plate 5 into the main body 1 from the state shown in FIG. At the same time, the other end is inserted in the direction of arrow 18 when the other end in the long axis direction is positioned inward from the opening edge 4.

The main cover plate 5 easily enters into the main body 1 as described above because the link member 16 and the hinge 17 allow the main cover plate 5 to move freely in the longitudinal direction.

After the main cover plate 5 is inserted into the main body 1, it is made parallel to the opening edge 4, the arm member 9 is passed over the opening edge, and the handle 11 is turned to the position shown in FIG.

Then, the function of the cam member 12 causes the connecting member 1 to be drawn outward from the arm member 9.

At this time, the auxiliary cover plate 6 comes into sliding contact with the main cover plate 5, and its curvature in the short axis direction is corrected and becomes flat.

After the auxiliary cover plate 6 becomes flat, when the connecting member I is further drawn as described above, the main cover plate 5 has both ends in the long axis direction touching the opening edge 4, so that its short axis The curvature in the direction is corrected, and the main cover plate 5 is tightly inscribed around the opening edge 4.

Note that the sliding surfaces of both hook plates 5 and 6 are preferably coated with tetrafluoroethylene resin or the like in order to improve lubricity.

It goes without saying that to remove the lid plate as described above, the procedure for putting the lid on is reversed.

As is clear from the above explanation, the sterilizer lid of this invention has a double structure consisting of a main lid plate and an auxiliary lid plate, so it can withstand even if the pressure inside the sterilizer body is quite high. It's watery.

'Also, since we have placed a heat insulating material between the main cover plate and the auxiliary cover plate,
The surface of the main cover plate does not get very hot.

Therefore, even if your hand touches the main lid plate when opening and closing the lid, there is no risk of getting burned.
