[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention can be implemented as in the first aspect of the present invention. That is, the vertical piece around the top plate placed on the upper surface of the opening of the kitchen counter is bent inward to form a hook-shaped cross section, and the seal packing attached along the periphery of the top plate is hooked. An insertion piece press-fitted into the space inside the shape, and a bottom portion pressed against the lower surface of the top plate,
The cross section including the insert piece and the vertical connecting piece that connects the bottom portion has a hook shape, and the insert piece is a seal packing made of an elastic body having a hollow central portion of the cross section. is there.

[0010] Then, by inserting the insert of the seal packing into the space inside the hook shape of the top plate, the insert having a hollow shape and elasticity is compressed and closely adhered to the inside space. Since the seal packing is firmly held by the top plate, the seal packing is prevented from falling off when the top plate is washed with water or placed on a kitchen counter, and the seal packing is more easily retained.

Furthermore, in order to seal the space between the top plate and the kitchen counter as in the second aspect of the present invention, the bottom of the seal packing is in contact with the kitchen counter in the opening direction of the kitchen counter. The obliquely extending tongue can be projected from the center left side, and a step can be provided below the thickness of the base located above the tongue to form a storage space for accommodating the tongue.

[0012] The tongue piece extending obliquely toward the opening direction of the kitchen counter at the bottom of the seal packing fits in the storage space even at the corner, and hermetically seals the gap between the top plate and the kitchen counter to prevent boiling. Water can be prevented from penetrating into the kitchen counter opening, and the tongues extend diagonally toward the kitchen counter opening direction. Improvement can be achieved.

[0013] Further, by reducing the thickness of the base located above the tongue piece to provide a storage space for the tongue piece, even if the tongue piece is pressed against the storage space side, the top plate is not pushed upward. It is possible to flexibly change the angle from a downward diagonal direction to a substantially horizontal state, and even when there is local unevenness or warpage on the kitchen counter top surface, the tongue piece creates a gap between the top plate and the kitchen counter. The two can be absorbed by elasticity to bring them into close contact with each other, thereby improving the hermetic sealing performance.

Furthermore, a hooking projection projecting upward from the hook shape is provided on the upper surface of the bottom of the seal packing, so that the intersection angle between the connecting piece and the bottom can be formed at an acute angle.

[0015] By forming the intersection angle between the connecting piece and the bottom portion to be an acute angle of 90 degrees or less, when the seal packing is mounted on the top plate, the bottom of the seal packing made of an elastic material has a hook-like shape of the top plate. The lower end is brought into contact with the locking projection to be pressed down and deformed, pulling in the surrounding vertical pieces and firmly adhering to the top plate, enabling the top plate to be placed downward on the corner when placed on the kitchen counter. It is possible to prevent collapse of the shape such as falling or biting, and to improve the hermetic sealing between the top plate and the kitchen counter at the corner.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. The same components as those of the conventional example shown in FIGS. 5 and 6 are denoted by the same reference numerals, and detailed description thereof will be omitted.

(Embodiment 1) FIG. 1 is a sectional view of a seal packing in a state where a top plate according to an embodiment of the present invention is placed on a kitchen counter. FIG. 2 is a sectional view of the seal packing in a state where the seal packing is mounted on the top plate.

In FIG. 1 and FIG. 2, a top plate 13 having a vertical vertical section 12 bent inward and having a hook-shaped cross section is placed on the upper surface of the opening 9 of the kitchen counter 1. A seal packing 14 made of an elastic material such as silicon rubber is interposed between the top plate 13 and the kitchen counter 1 so that the top plate 1
3 and the kitchen counter 1 are hermetically sealed.

The seal packing 14 is composed of three parts: an insertion piece 15 and a bottom part 16 located on the lower surface of the top plate 13, and a connecting piece 17 connecting the insertion piece 15 and the bottom part 16, and has a hollow at the center of the cross section. The insertion piece 15 having the hole 15 a is inserted into the hook-shaped inner space in which the vertical piece 12 of the top plate 13 is bent inward while undergoing compression to reduce the width B, and is attached to the top plate 13.

Next, the operation will be described. Hollow molding
The insert piece 15 having elasticity has a width B in compression and closely adheres to the hook-shaped inner space of the top plate 13,
Since the upper surface 15b abuts against the inner surface 13b of the top plate 13 to receive the reaction force against the compression, the seal packing 14 is firmly held by the top plate 13, so that the seal plate 14 can be washed and cleaned with the top plate 13 or the kitchen counter 1 The seal packing 14 can be sufficiently resisted even if it receives a pulling force at the time of mounting on the device, and the falling off of the seal packing 14 can be prevented.

A tongue piece 18 is provided on the bottom 16 of the seal packing 14. The tongue piece 18 has a shape extending obliquely toward the opening 9 of the kitchen counter 1 and the thickness of a base portion 16a located above the tongue piece 18 is reduced by providing a step H to reduce the thickness of the tongue piece. 18 storage spaces 1
9 is provided as shown by oblique lines.

In FIG. 3, the angle of intersection θ between the connecting piece 17 and the bottom 16 is an acute angle of 90 degrees or less. In FIG. 4, the rectangular top plate 13 has four corner portions 3. The seal packing 14 is bent at the corner 3 with the connecting piece 17 inside. At this time, as shown in FIG. 2, the bending center C is closer to the left than the connecting piece 17 because the insertion piece 15 is located on the left side. And
The bottom portion 16 grows more to the left from the bending center C,
Since the tongue piece 18 has the least extension at the right end, the tongue piece 18 naturally enters the storage space 19 at the corner portion 3.

Therefore, as in the case of the straight portion, the tongue piece 18 does not have wrinkles or the like at the corner portion 3, can be in close contact with the kitchen counter 1, and has good sealing properties. Intrusion can be prevented.

When the top plate 13 is placed on the kitchen counter 1, the tongue piece 18
The angle can be freely changed from a lower oblique direction to a substantially horizontal state without pushing up the top plate, and even if there is unevenness or warpage on the upper surface of the kitchen counter 1, it is absorbed by local deformation of the tongue piece 18, and the top plate is absorbed. A large gap between the kitchen counter 13 and the kitchen counter 1 can be closed to maintain hermetic sealing.

The seal packing 14 is connected to the connecting piece 1.
By forming the intersection angle θ between the bottom 7 and the bottom 16 to be an acute angle of 90 degrees or less, the bottom 16 of the seal packing 14 made of an elastic body is attached downward by the lower end 13 a of the top plate 13 at the time of attachment to the top plate 13. However, it is attempted to escape to the right side of the figure by the reaction force for maintaining the intersection angle, but because it is received by the locking projection 20, it is slightly pulled into the vertical piece 12 side of the top plate 13 to enable strong adhesion, The shape of the connecting piece 17 such as downward sagging or biting generated at the corner 3 of the top plate 13 is prevented, and the hermetic sealing between the top plate 13 and the kitchen counter 1 is improved.

[0026]

As is clear from the above description, the following effects can be obtained by the seal packing of the top plate of the present invention.

According to the first aspect of the present invention, the vertically formed insertion piece of the seal packing made of an elastic body is press-fitted into the interior space formed by bending the vertical piece of the top plate inward and forming a hook shape. As a result, the seal packing is firmly held on the top plate, so that the seal packing does not fall off during cleaning or mounting on the kitchen counter, and the seal packing has good retaining properties.

According to the second aspect of the present invention, a seal is provided between the top plate and the kitchen counter by providing a tongue at the bottom of the seal packing and extending obliquely in the opening direction of the kitchen counter. The appearance is good by improving the sealing performance and eliminating the protrusion of the top plate to the outer periphery.

Further, by providing a storage space for the tongue pieces by providing a stepped portion under the base located above the tongue pieces and having a reduced thickness, the tongue pieces abut on the kitchen counter when placed. It can be kept in the storage space even if it is almost horizontal, so it can be kept horizontal without pushing up the top plate. And even if there is unevenness or warpage on the upper surface of the kitchen counter, the tongue can fill the local gap between the top plate and the kitchen counter while flexibly changing the angle from the lower oblique direction to the substantially horizontal state. This has the effect of further increasing the hermetic sealing performance.

Further, according to the third aspect of the present invention, a mounting projection is provided on the upper surface of the bottom left end of the seal packing so that the intersection angle between the connecting piece and the bottom is formed to be an acute angle, so that it is mounted on the top plate. Occasionally, the bottom of the seal packing, which is made of an elastic body, has a locking projection stopped at the lower end of the hook shape of the top plate, the acute intersection angle between the connecting piece and the bottom is enlarged to the obtuse side, and the vertical piece is firmly pulled to the left This prevents the downward tilting that occurs at the corners of the top plate, prevents pinching when placed on the kitchen counter, and improves the hermetic sealing between the top plate and the kitchen counter. is there.
