Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a kettle used to boil hot water, and more particularly to a whistle-blowing kettle that emits a whistling sound when hot water is boiled.

[0002]

[Prior art]

 There are two types of kettles: a so-called whistle-blowing kettle that has the function of making a whistle-like sound to notify when hot water is boiling, and a general kettle that does not make a sound.

The latter general kettle is composed of a kettle body and a lid having a vapor escape hole, which is simply fitted in a water injection opening provided on the upper surface of the kettle body. In the case of the whistle-blow kettle, not only the lid is fitted over the water injection opening, but also the lid is closed without creating a gap between the water injection opening and the lid, and the vapor escapes. Steam generated using a lid without holes is mainly discharged from the hot water supply port.

In addition, recently, there are some that further improve the chemical durability or make the appearance beautiful and further enhance the commercial value by applying enamel processing to the inner and outer surfaces of the kettle.

However, if an attempt is made to construct a whistle blowing kettle using a kettle body and a lid body that have undergone enamel processing on the entire kettle, a water injection opening provided on the top surface of the kettle body and the water injection opening There is a dimensional deviation from the lid that is fitted in the opening, the lid cannot be fitted, or a considerable gap is created between the two, and steam escapes from there and the whistle blows. There were drawbacks such as the difficulty of producing sound, and it was very difficult to cover the kettle body and lid without a gap.

That is, in enamel processing, the surface of a metal plate such as an iron plate is coated with glassy glaze and fused at a high temperature, so that it is difficult to uniformly coat the surface of the metal plate. Even so, variations in thickness occur. This variation in thickness is noticeable at the edges of the enamel processed product.

Therefore, even if the kettle body is subjected to enamel processing, in order to adapt the lid body to the water injection opening on the upper surface of the kettle body, one without enamel processing, for example, stainless steel must be used. I have to. However, the kettle body that has been made with such an enamel process and the lid made of stainless steel is not well-balanced in appearance, and its commercial value is inevitably lower than that of the enamel processed product. It is inevitable.

Therefore, as a means for using the kettle body and the lid body that have been subjected to enamel processing, the lid body is weighted to be covered, or a peripheral portion of the water injection opening on the upper surface of the kettle body is made of stainless steel or the like. There is one in which a enamel-processed lid body can be closely fitted by winding a ring and making the peripheral portion a uniform surface.

[0009]

[Problems to be solved by the device]

 However, weighting the lid is uneconomical because the lid is not too heavy and cumbersome to handle, and requires extra material.On the other hand, the water injection opening on the top surface of the kettle body is uneconomical. In the method of winding a ring made of stainless steel or the like around the peripheral edge of the ring, the process of winding the ring is very time-consuming and inefficient, resulting in low productivity.

Furthermore, since the lid body can be freely inserted and removed, it is necessary to consider the aesthetic appearance of the inside of the lid body. In other words, when applying enamel processing to the lid, it is necessary to prevent excess glaze from remaining inside the locking edge (see 16 in Fig. 5) that is provided so that the lid does not fall into the kettle body. However, it was very troublesome to remove this extra glaze.

As described above, it is extremely difficult to make the kettle body and the lid body both enameled, and to manufacture the kettle body in which the lid body is fitted to the kettle body without any gaps easily and efficiently. It was

The present invention is intended to address such a problem, and has achieved its object by completing the invention described below.

[0013]

[Means for Solving the Problems]

 As shown in FIGS. 1 to 4, the present invention comprises a lid (2) for fitting into a water injection opening (8) on an upper surface of a kettle body (1), a top plate (3) and the top plate (3). This is a combination of (3) with a bottomed cylindrical inner lid part (4) that integrally covers the bottom side part from the peripheral side part.

Further, according to the present invention, the kettle body (1) and the top plate portion (3) of the lid body (2) are subjected to enamel processing so that the inside of the lid body (2) inserted into the kettle body (1). The lid (4) is also made of a combination of stainless steel.

Furthermore, the bottom surface of the inner lid portion (4) having a bottomed cylindrical shape, which is combined with the top plate portion (3) of the lid body (2), is curved outward so that the bottom surface has elasticity. It is also a thing.

[0016]

[Action]

 Since the bottom portion is integrally covered with the bottomed cylindrical inner lid portion from the peripheral side portion of the top plate portion, the side surface of the lid body is a flat and even surface, and the lid body is fitted on the kettle body without any gap.

Further, a hollow portion is formed between the integrated top plate portion and the inner lid portion, and the air is sealed in the hollow portion, so that the lid is double and the kettle is double. It will have a heat retaining effect.

Further, when the lid body is fitted on the kettle body, the bottom surface of the inner lid portion is curved as the side surface of the inner lid portion is pressed from the surroundings, so that the lid body can be easily fitted. Since the bottom surface of the inner lid part, which has a leaf spring shape and has a biasing force by bending after fitting, tries to return to its original state by the biasing force, the lid body is pressed against the kettle body by its pressure contact force. It will be firmly fitted without a single layer gap.

[0019]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. The kettle lid (2) of the present invention comprises a top plate portion (3), an inner lid portion (4) and a knob (5) as shown in FIGS. 1 and 2, and the top plate portion (3) is shown in FIG. The shape of only the upper half of the ordinary lid (13), that is, the shape without the hakama (17), is pre-enameled, and then the inner lid (4 with a bottomed cylindrical shape is formed. ) To form a lid (2). At this time, a step portion is provided in the middle of the peripheral side portion of the inner lid portion (4) so that the top plate portion (3) does not completely fall into the inner lid portion (4). The cover may be formed by bending the upper edge around the inner lid (4) inward and caulking (see Fig. 3), but in order to prevent water from entering the inside of the lid, the top plate (3) It is advisable to apply a resin or the like to the contact portion between the inner lid portion (4) and the inner lid portion (4) in advance and then crimp.

In addition, the lower side of the inner lid portion (4) of the lid body (2) is tapered to facilitate fitting into the kettle body, and a plurality of protruding locking portions (dowels) are provided on the circumferential side portion. You may make it possible to provide a tighter lid. Needless to say, the lid of the kettle according to the present invention is not limited to the kettle and can be used as a lid of a general closed container because of its good hermeticity.

[0021]

【effect】

 The lid configured as described above has the following effects. By combining it with the enamel-processed kettle body, it is possible to make a kettle with a beautiful aesthetic appearance and a high commercial value. Since the shape and structure of the lid is extremely simple, it can be manufactured very easily and efficiently. By making the inside of the lid an inner lid such as stainless steel, it is not necessary to perform enamel processing on the inside of the lid, which saves labor and weight, and the enamel portion does not appear inside the lid. , Very hygienic. In other words, the enamel part tends to get bleached when the steam hits directly, but by covering it with stainless steel or the like, the fear disappears. By making the shape of the inner lid part a cylindrical shape with a bottom, the appearance of the inside of the lid is very good and cleaning can be easily performed. From this, it can be said that it is very hygienic. Since the inside of the lid is a hollow double-layered lid, the heat retention effect can be improved. By bending the bottom surface of the inner lid, the elasticity of the inner lid is further strengthened, and the opening of the lid can be covered very easily, and after the lid is closed, the main body of the kettle and the lid are closed. It is possible to close the lid more closely. Since the kettle body and lid are fitted more closely, it is not necessary to have a large-capacity kettle to sound the whistle of the whistle, and it is assumed that the kettle has a whistle blowing function even in a small kettle. be able to. In other words, the amount of vapor escaped is much smaller than that of the conventional one, so that even if the internal volume is small, sufficient vapor pressure for whistling can be obtained.
