Description

[Detailed description of the invention] [Industrial field of application] This invention relates to a whistling kettle.

[Conventional technology]

As shown in Figure 5, a whistle kettle is a kettle with a spout hole on the kettle body A that is closed with a small lid with a whistle. A whistle is sounded inside to let you know when the water is boiling.

In addition, even if the amount of steam generated increases, the lid of the kettle will not lift up and the steam will not escape from the opening, so the lid and opening are equipped with a lid lifting prevention structure. There is.

In addition, to prevent the lid from lifting up, conventional kettles use elastic materials such as aluminum for the kettle body and stainless steel for the lid. A friction resistance portion for fixing the lid is formed on one of the parts to prevent the lid from lifting up due to an elastic force. R is the handle, and N is the push button for opening the small lid.

[Problem that the invention attempts to solve]

The above-mentioned conventional whistling kettle uses frictional resistance and pressure action between the metals to prevent the lid from lifting up, and as a result, the lid creaks when attached and removed, giving a poor feeling of operation.
Moreover, not only is it difficult to control dimensions due to the narrow tolerance range of dimensions, but also a process of pressing the lid is required.

The purpose of this invention is to provide a novel lid lifting prevention structure for a whistling kettle, which provides a smooth feeling when attaching and removing the lid, and allows for a wide range of dimensions for preventing the lid from lifting up.

[Means for solving problems]

In order to solve the above problem, this invention consists of a hem ring that can be fitted on the outside of the rising edge of the lid fitting opening of the kettle body, and the ring is a molded product of heat-resistant reinforced plastic with a vertical width dimension. The height of the rising edge is approximately equal to the total height of the rising edge of the lid fitting opening and the peripheral plate portion of the lid that rests on the rising edge, and has an inner diameter on the inner circumferential surface that matches the outer diameter of the rising edge. A bulging annular portion having a vertical width dimension smaller than the bulging annular portion is provided, and protrusions for holding down the circumferential side plate portion of the lid are provided at multiple locations in the circumferential direction on the inner circumferential surface above the bulging annular portion, and at least these protrusions are used as the center. , the vicinity thereof is hollow, and each side of the protrusion except for one side is cut to form a tongue-shaped protrusion, the hem-wrapping ring is externally fitted on the rising edge of the opening, and the upper end of the rising edge is formed. This is a structure of a lid floating prevention part of a whistle kettle, which is fixed in an unremovable manner by being pressed and bent outward so as to rest on the upper edge of the bulging annular part.

[Effect]

The edge wrapping ring is firmly attached to the outside of the rising edge of the lid fitting opening, and a tongue piece having a lid pushing protrusion is provided on the inner peripheral surface of the portion of the ring that projects upward from the rising edge. When the lid is attached to the opening, it will move back once, but the restoring elasticity of the material will press against the peripheral plate of the lid and prevent the lid from floating freely.

〔Example〕

FIG. 1 shows the main parts of the whistle kettle according to the present invention, where 1 is the kettle body, 2 is an opening into which a lid 3 is fitted, 4 is a spout, and 5 is a handle.

Reference numeral 6 denotes a small lid that closes the spout 4, and the portion that overlaps the spout is ring-shaped, and the ring-shaped portion 7 may hold a flute 8, or the flute may be integrally molded into the small lid itself. can.

The flute 8 consists of upper and lower dish-shaped plates 9 and 10, each with a small hole in the center so that the whistle will sound when steam passes through it rapidly.Since the small lid with the flute is well known, details will be given here. The explanation will be omitted.

The small lid 6 is designed to be turned over when pouring hot water or stopping the whistle, and 24 is a lid opening knob protruding from one side of the small lid 6. Additionally, this small lid has been given the ability to recover in the closing direction.

A hem ring 11 made of a heat-resistant, fiber-reinforced plastic molded product is fitted onto the opening 2 of the kettle body 1 into which the lid 3 is fitted, and is fixed in an unremovable manner.

As shown in FIG. 2, the hem ring 11 has a bulging annular portion 12 formed in the lower half of the inner peripheral surface.

The inner diameter of the bulging annular portion 12 is made to match the outer diameter of the rising edge 13 of the opening 2, and the longitudinal width is slightly smaller than the height of the rising edge 13. By pressing and bending the upper end outward so as to rest on the upper edge of the bulging annular portion 12, the edge wrapping ring 11 can be firmly attached.

The upper half 14 of the hem ring 11 is close to the circumferential plate 15 of the lid 3, and the inner circumferential surface of the upper half 14 is provided with protrusions 16 in pressure contact with the circumferential plate 15 of the lid at multiple locations in the circumferential direction. is formed.

The hem ring 11 is hollow with a downward opening except for the bulging annular part 12, and the inside of the protrusion 16 that presses against the lid is also a hollow part 17.
6 is in the center, and in the vicinity thereof, except for the upper side, cuts 18 reaching the hollow portion 17 are made on the other three sides, and therefore the protrusion 16 is a tongue piece that retracts when subjected to external force, but always protrudes. It has directional restorability.

The hem ring 11 has two handle attachment portions 19 protruding upwardly at two diagonal positions, and a flat convex portion 20 on the opposite inner surface of the lower end of the handle 5 is fitted onto the opposite outer surface thereof. A matching flat recess 21 is formed. 22 is a hole through which the handle connecting stud 23 is passed.

〔effect〕

The structure of the lid floating prevention part of the whistle kettle of this invention has the following effects.

(1) The operation of attaching and detaching the lid is smooth because the metal and plastic fit together.

(2) Since the protrusion for preventing the lid from floating has a hollow dorsal side and a tongue-like shape, it has high resilience in the lid pressure contact direction, and therefore the permissible range of dimensions of the lid from floating is wide. It is wider and the dimensions are easier to manage.
