Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a sealed container that can have a container body of different sizes with respect to a lid body, and can maintain its sealing performance.

[Conventional technology]

Conventionally, as a sealed container, a specific lid body is fitted onto a specific container body, and a sealing state between the two is maintained by a packing material interposed between the two or by a fixing means.

[Problem that the invention attempts to solve]

However, depending on these sealed containers, the former requires a fixing device such as a turnbuckle to seal the lid to the container body, and the other requires a sealing material, so although they have mutual sealing properties, However, when the size of the container body is changed to a certain lid, there is a problem in that it cannot be fitted onto the outside, and there is also a problem with its sealing performance. In particular, when food or the like is stored in the sealed container and the contents are heated in a microwave oven, the lid may come off due to the increase in internal pressure. The present invention aims to provide a sealed container which allows a single lid to be fitted onto container bodies of different diameters and which has a sealing property, in contrast to such conventional sealed containers.

[Means for solving problems]

In order to achieve the above object, the present invention has a container body for storing articles; the container body is made of ceramics, earthenware, porcelain, etc., and can be externally fitted onto the mouth edge of the container body, and the inner surface is directed downwardly and inwardly. An annular fitting piece is provided with an inverted tapered shape, and a tapered abutment surface is formed on the inner surface of the fitting piece, extending from the bottom of the fitting piece to the bottom surface of the lid and sloping downward and outward. It is an object of the present invention to provide a sealed container in which a soft sealing material is combined with a lid formed by baking silicone rubber.

[Effect]

The structure of the present invention is as described above, so that when the lid is externally fitted onto the container body, the soft sealing material of the annular fitting piece provided around the lid is tightly fitted to the rim of the container body. In addition to maintaining the sealing performance of the lid to the main body, by forming a tapered contact surface on the soft sealing material, it becomes possible to apply container bodies of different sizes to one lid. .

〔Example〕

The details of the present invention will be explained based on further illustrated embodiments. FIG. 1 is a partial longitudinal cross-sectional view of a first embodiment of a sealed container according to the present invention, in which numeral 1 is the container body and 2 is its lid. Both the container main body 1 and the lid 2 are made of ceramics, earthenware, porcelain, etc., and are suitable for storing food in this sealed container and using it for heating with electromagnetic waves. As shown in the figures, the container body 1 can be of various shapes, such as a round planar shape or a square shape, and there is a vertical wall 4 around the bottom wall 3 of the container body 1, which forms the container. Its upper end forms the rim. The lid 2 is fitted onto the rim of the container body 1 to provide a seal against the container body 1, and the illustrated example shows the lid 2 fitted over the rim of the container body 1. . In the figure, 5 is the top plate of the lid body 2, and 6 is its annular fitting piece, and the inner surface of the fitting piece 6 has a so-called reverse tapered shape that is inclined downwardly and inwardly as shown in the figure. The inner surface of this annular fitting piece 6 has the following as shown in the figure.
Further, the soft sealing material 7 is formed with a tapered abutting surface inclined downwardly and outwardly from the lower part of the fitting piece 6 to the lower surface of the lid top plate. Reference numeral 8 denotes the corresponding contact surface, which is a sloped surface in the downward and outward direction as shown in the figure. Therefore, this annular fitting piece 6
Due to the combination of the soft sealing material 7 and the sealing material 7, the surface of the sealing material 7 has an inclined surface in the downward and outward direction, but the thickness increases toward the upper part of the sealing material, increasing the elasticity. In addition, 9 is the fitting piece 6
This is a recess formed on the inner surface, and is used to forcefully attach the soft sealing material 7 to the inner surface of the annular fitting piece 6. Further, reference numeral 10 denotes a ridge for regulating the attachment position of the sealing material 7, which is provided on the lower surface of the top plate 5 of the lid body 2 at a position in contact with the upper end side edge of the soft sealing material 7, and the ridge 10 for regulating is provided. Possibly protrusion 10
When forming the sealing means by adhering the soft sealing material 7 to the inverted triangular space formed by the inner surface of the annular fitting piece 6, the sealing material adhesion position under the top plate 5 is aligned with the regulating protrusion 10. Therefore, the liquid is prevented from flowing to the center of the top plate 5. The container body 1 shown in FIG. 3 has a rim with an outward protrusion on the upper end of the outer surface, whereas the container body 1 in FIG. 1 has a planar inner and outer surface. 11 is shown. When the container main body 1 shown in FIG. 3 is press-fitted into the sealing material 7 of the lid body 2 having the sealing material tapered downward and outwardly, the opening edge protrusion 11 portion will be attached to the surface 8 of the soft sealing material 7. By pressing the annular fitting piece 6 in the direction of the reverse tapered surface of the inner surface, the ring is fitted, and the sealing state is completed, and at the same time, it becomes difficult for the lid 2 to come off from the container body 1.

The soft sealing material 7 is a material that has heat resistance and is soft depending on its sealing performance and the purpose of use when fitting the lid 2 to the container body 1 and sealing it. Then the silicone rubber is baked on. This silicone rubber is made of methylvinyl polysiloxane as a main component, methylhydrogen polysiloxane as a crosslinking agent, silicon dioxide as a filler, a platinum compound as a catalyst, silanes having silanol groups or amino groups as an adhesion aid, and reactive It is preferable to use silicone rubber using a tin-based compound as a control agent. The silicone rubber is Shin-Etsu silicone rubber KE-1251 (trade name of Shin-Etsu Chemical Co., Ltd.), and this silicone rubber is a one-component heating/self-adhesive type that can be heated to a temperature of 10°C or higher. It can be cured and bonded in a short time and becomes a rubber elastic body, and the use of this material as the present soft sealing material 7 is a preferable example in terms of its intended use.

Therefore, in order to use the sealed container according to the present invention shown in FIG.
If they are fitted together, the tapered inner surface 8 of the soft sealing material 7 will come into contact with the mouth edge of the container body 1, and if pressure is applied in the direction of fitting each other, the degree of fitting into each other will increase and at the same time , the soft sealing material 7 is compressed, and the compressed portion is released upward or downward from the compressed position of the abutment surface 8, further toward the reversely tapered inner surface of the annular fitting piece 6, that is, upward in the figure, and is tightly fitted. It is of a large size and functions as a sealed container. Since the soft sealing material 7 is set to have an inverted triangular shape as described above, that is, a shape tapering downward and outward, it is not limited to the container body shown by the solid line in FIG. It is possible to apply container bodies 1 having different diameters in a state of being closed, and to improve the degree of sealing, and at the same time, to make various combinations of the container body 1 and the lid 2. In addition, 12 is a hole for air release, and the container body 1
When food is stored inside and heated by electromagnetic waves and the vapor pressure inside increases, air is vented through the holes 12. Next, in the embodiment shown in FIG. 4, a soft sealing material 7 is provided on the inner surface of the annular fitting piece 6, and at the same time, a soft sealing material 7' is attached to the entire lower surface of the top plate 5 of the lid body 2. It is what it is.
By adopting such an example,
Not only can the seal portion having the tapered contact surface 8 of the soft seal material 7 be used, but also the flat seal material 7' on the lower surface of the top plate of the lid body 2 can be used, as shown by the imaginary line.
It can also be used as a lid 2 for a smaller container body 1.

In the case shown in FIG. 5, the container body 1 and the lid 2 are formed as a hollow container.
This hollow container is preferably made of ceramics, pottery, porcelain, etc., and has a hollow interior. ,
It can be used in the same way as the sealed container shown in FIG. In this state, not only can one lid 2 be used for container bodies 1 of different diameters, but also food can be stored in the sealed container and heated using electromagnetic waves because it has a hollow side wall. In such cases, or even when storing externally heated food in this container, it is possible to prevent the temperature of the internal contents from dropping or rising, and it can be used as a sealed container. It not only has the function of sealing, but also has the function of preventing heat conduction.

[Effect of idea]

As described above, the sealed container according to the present invention is made of a container body for storing articles and ceramics, earthenware, porcelain, etc., and can be fitted onto the rim of the container body, and the inner surface is placed around the periphery in a downward and inward direction. An annular fitting piece is provided with an inverted tapered shape, and a tapered abutment surface is formed on the inner surface of the fitting piece, extending from the bottom of the fitting piece to the bottom surface of the lid and sloping downward and outward. Since it consists of a lid body made of a soft sealing material by baking silicone rubber,
The degree of sealing achieved by fitting them together is high, and container bodies with different diameters can be sealed with one lid.Moreover, the soft sealing material is a lid made of silicone rubber or ceramics, etc. Since it is baked into the body, even if there is some dimensional error in the lid itself, the soft sealing material will firmly adhere to the lid without wobbling and will not fall off from the lid. In addition, it has high heat resistance and does not deteriorate when used with heating by electromagnetic waves, etc., maintains high sealing performance, and can withstand long-term use.
