Description

  The present invention relates to a valve suitable for being attached to a container suitable for heating food by a microwave oven or other heating device, and a heating container equipped with this valve.

  A container used when heating food with a microwave oven or other heating device is composed of a container main body and a lid that covers the container. Usually, the container main body and the lid are made of synthetic resin or glass having good heat resistance. Or it consists of pottery.

In order to be able to store food frozen and refrigerated using such a heated container, it can be completely sealed, keep the food dry, and prevent the smell of other foods from moving. Furthermore, it is preferable that the humidity of the food can be maintained.
However, if this container is used with the heating device without a lid, food in the container may burst and scatter, and the inside of the heating device may be soiled. Moreover, if it heats by the said heating mounting | wearing without a lid | cover, the surface of a food will dry and a taste will be impaired.
To prevent this from happening, you must put a lid.

  Therefore, in order to be able to heat this container with the heating device with the lid on, the lid over the container body is used for discharging pressurized air / overwater vapor, or when it is cooled at the end of heating and in the refrigerator It is necessary to provide a hole for eliminating the negative pressure in the container generated in the container, and to provide a valve body having a protrusion capable of closing the hole in the lid so that the hole can be opened and closed as necessary. (For example, refer to Patent Document 1).

When heating the food contained in the container body, the valve attached to the lid is opened with the lid closed, and the protrusion that has blocked the hole provided in the lid is opened. In addition, the inside and outside of the container body can be brought into communication with each other through the opened hole, and can be heated. When the food is heated, the pressure in the container body rises, but this pressurized air and excess water vapor generated at that time are smoothly discharged from the open holes. If the open valve is closed, it can be used in the same way as a normal sealed container.
Also, when the internal pressure becomes low when the heating is finished or when it is cooled in the refrigerator and the lid cannot be removed due to sticking to the container body, the negative pressure generated in the container can be reduced by opening the closed valve body. It can be eliminated and the lid can be easily removed.

JP 2009-143626 A

  The valve body provided in the container described in Patent Document 1 is integrally formed on the lid body through a hinge with the above-described synthetic resin having good heat resistance by a normal method such as using a mold. Therefore, the valve body is also hard like the lid body, and even if the hole provided in the lid body is closed by the protrusion of the valve body, it cannot be completely sealed. In addition, the mold for integrally molding the valve body and the lid body is not only complicated, but also has a drawback that the cost for manufacturing the mold increases.

  On the other hand, it has also been attempted to integrate the valve body made of a soft material into the cover made of the synthetic resin by double molding of the soft material, but the soft material is difficult to withstand the temperature, Depending on how heat is applied, the valve body undergoes a dimensional change, and there is a drawback in that stable sealing performance in a wide temperature range from low temperature to high temperature cannot be maintained.

  Further, when the valve body and the lid body are connected, there is a drawback that it is difficult to clean the valve body and the lid body.

  In order to eliminate these disadvantages, we have devised a valve structure made of silicone or other heat-resistant soft material that has high heat resistance and high flexibility, and attaches this valve body to the lid. It can be set as the container which can be cooked with a microwave oven or other heating devices. That is, a hole is formed in the valve body for discharging pressurized air / super-steam, or for eliminating the negative pressure in the container that occurs when heating is completed and when the refrigerator is cooled in the refrigerator. By connecting a plug made of the same material, such as silicone or other heat-resistant soft material, through the connecting portion, the valve body hole can be closed by a protrusion provided on the plug body. The above disadvantages can be solved.

  The valve body made of a heat-resistant soft material such as silicone can be attached to and detached from the cover body simply by forming a valve mounting hole in the cover body. Therefore, if it is a container having heat resistance, it can be transformed into a container that can be cooked by a microwave oven or other heating device simply by mounting the valve in a valve mounting hole formed in the lid. it can.

  On the other hand, in a heating container consisting of at least a heat-resistant container body and a lid that covers the container body, a valve mounting hole is formed in the lid, and this hole is used for discharging pressurized air and excessive water vapor, or At the end of heating and when cooled in the refrigerator, a valve body made of silicone or other heat-resistant soft material with holes for eliminating the negative pressure in the container is attached, and this valve body is made of the same material If a plug made of a heat-resistant soft material such as silicone is connected, and the hole of the valve body can be closed by a protrusion provided in the plug through the connection, a microwave oven or other It becomes a container which can be cooked by a heating device.

  A valve for a heating container according to the present invention is a valve made of silicone or other heat-resistant soft material that can be attached to and detached from a valve mounting hole formed on a lid body that can be covered at least on a heat-resistant container body, A hole is formed in this valve body for discharging pressurized air and excess water vapor, or for eliminating the negative pressure in the container that occurs when heating is finished and when it is cooled in a refrigerator. The plug body made of a heat-resistant soft material such as silicone is connected, and the hole of the valve body can be blocked by the protrusion provided in the plug body through the connection portion. To do.

  In this case, the valve body made of a heat-resistant soft material such as silicone can be attached to and detached from the lid body simply by forming a valve mounting hole in the lid body. If it is a high container, it is very easy to transform it into a container that can be cooked by a microwave oven or other heating device simply by mounting the valve for a heating container according to the present invention in the hole for valve mounting formed in the lid. Can be made.

  If the size of the valve mounting holes to be formed in the lid body is the same, the size of the container body and the lid body to cover the same will differ, but the valves for the heating container have the same common size. There is also an advantage that can be used.

  In particular, when the valve for the heating container is made of a silicone material, the heat resistance temperature of the silicone material itself is about 230 ° C. to 280 ° C., which is extremely higher than that of the synthetic resin. If it is installed in the hole of the lid of a container made of heat-resistant glass or ceramics, it will be a container for heating using an oven, and the valve will not be thermally deformed even when heated, and it has excellent durability Therefore, there is an advantage that it can be used for a long time.

  In addition, since the silicone material is also flexible, not only can the sealing and sealing properties of the heating container equipped with the heating container valve be improved, but the valve can be removed from the lid very easily. Since this is possible, there is an advantage that the valve and the lid are easy to clean.

  On the other hand, the heating container according to the present invention comprises a container body having at least heat resistance and a lid body that covers the container body. The lid body is provided with a valve mounting hole, and this hole is used for discharging pressurized air and excessive steam. Or a valve body made of soft heat-resistant silicone or other material with holes to eliminate the negative pressure in the container that occurs when heating is finished or when it is cooled in a refrigerator. A plug body made of the same material, such as silicone or other heat-resistant soft material, is connected, and the hole of the valve body can be blocked by a protrusion provided on the plug body through the connection portion. It is a feature.

  According to this heating container, a hole for attaching a valve body is formed in advance in a lid body that covers the container body when molding with a mold, or a valve body is attached later to the lid body having no hole. Since the heating container valve can be easily installed later in this hole, the open container without the valve is made into a container that can be cooked by a microwave oven or other heating device. It is very easy to upgrade.

In particular, when the valve for the heating container is made of a silicone material, the mold cost for molding the valve made of the silicone material is extremely inexpensive, and further, the lid is molded for mounting this valve. The mold for use in this process requires only a very simple structure that simply opens a hole in the lid, so it is necessary to mold various types of heating containers with different shapes and sizes. The cost advantage is extremely large.
Moreover, since the valve body is detachable from the lid body and is not integral, the structure of the mold is not complicated compared to the case where the valve body and the lid body are molded integrally, and the mold cost is low. is there.

A handle extending in the lateral direction protrudes at a facing position in the peripheral portion of the container body, and a hinge lock is formed at a position facing the both handles on the peripheral portion of the lid body that covers the container body, The container body may be covered with a lid, and the handles are fitted into respective holes formed in both hinge locks so that the lid can be locked to the container body with both hinge locks.
In this case, even when both hinge locks are released and the lid is opened, the food in the container body remains hot, using both handles extending laterally from the container body. Can be carried with bare hands.

  If the heating container valve according to claim 1 is used, the valve body made of a heat-resistant soft material such as silicone can be freely attached to and detached from the lid body simply by forming a valve mounting hole in the lid body. If it is a highly heat-resistant container, it can be cooked by a microwave oven or other heating device simply by mounting the heating container valve according to the present invention in the valve mounting hole formed in the lid. It can be very easily transformed into a possible container.

  If the size of the valve mounting holes to be formed in the lid body is the same, the size of the container body and the lid body to cover the same will differ, but the valves for the heating container have the same common size. There is also an advantage that can be used.

  In particular, when the valve for the heating container is made of a silicone material, the heat resistance temperature of the silicone material itself is about 230 ° C. to 280 ° C., which is extremely higher than that of the synthetic resin. If it is installed in the hole of a container made of heat-resistant glass or ceramics, it will be a container for heating using an oven, and this valve will not cause thermal deformation even when heated, and it has excellent durability. There is also an advantage that it can be used for a long time.

  In addition, since the silicone material is also flexible, not only can the sealing and sealing properties of the heating container equipped with the heating container valve be improved, but the valve can be removed from the lid very easily. Since this is possible, there is an advantage that the valve and the lid are easy to clean.

  According to the heating container of the second aspect, the valve body mounting hole is formed in advance in the lid body to be covered with the container body during molding by the mold, or the lid body having no hole is formed in the rear body.

An example of a heating container valve according to the present invention and an example of a heating container equipped with the valve will be described in detail with reference to the drawings.
The heating container valve A illustrated here is a valve formed on the lid 2 that is a part of the heating container B as shown in FIG. 4, for example, suitable for heating food by a microwave oven or other heating device. It is detachable from the mounting hole 2a. As shown in FIG. 1, the heating container valve A includes a valve body 3 made of a silicone material, and a plug body 4 made of a silicone material connected to the valve body 3 and made of the same material as the valve body 3. It is made up of.
Hereinafter, although the case where the valve body 3 and the plug body 4 are made of silicone is illustrated, they can be made of a heat-resistant soft material other than the silicone material.

  In addition, the heating container B suitable for heating food with a microwave oven or other heating devices is a bottomed container body 1 having at least heat resistance, and can be placed on the container body 1. It consists of a lid made of the same material. A heat-resistant synthetic resin, heat-resistant glass, or heat-resistant ceramic can be used. Examples of the synthetic resin having good heat resistance include polyolefin resins such as polypropylene and polyethylene terephthalate.

The details of the valve body 3 are such that the upper part 3a has a disk shape as shown in FIGS. 4 to 6, and is lowered one step so that the vicinity of the center becomes a round depression 3b. The peripheral edge of the depression 3b It is bent so that it gradually becomes lower as it goes to the outside.
A ring-shaped groove 3d that protrudes in a umbilical shape from the upper part 3a of the valve body 3 downward and fits into the hole 2a between the umbilical protrusion 3c and the upper part 3a. Is formed.
On the other hand, the valve body 3 is formed with a round hole 3e that reaches the back surface (lower end surface) of the protruding portion 3c from the recess 3b. This hole 3e is for discharging the pressurized air and excess water vapor in the container B, or for eliminating the negative pressure in the container that occurs when the heating is completed and when the container B is cooled in the refrigerator.

The valve body 3 is connected to the valve body 3 by the connection part 3f on the valve body 3 side and the connection part 4a on the plug body 4 side, and the connection parts 3f and 4a can be folded at least in two. A hinge portion 5 is formed between the two.
Further, a stepped flat surface portion 4b that can be fitted into the recess 3b is formed in the vicinity of the tip of the connecting portion 4a of the plug body 4, and a protrusion 4c that protrudes upward from the center thereof is formed.

  On the other hand, the disc-shaped upper part 3a of the valve body 3 is formed with a recess 3g having a width capable of fitting the connecting part 4a on the plug body 4 side from the connecting part 3f to the peripheral part of the recess 3b. .

  When the ring-shaped groove 3d of the valve body 3 is fitted into the valve mounting hole 2a formed in the lid body 2, the valve body 3 can be mounted in the hole 2a. The heating container B is provided with a hole 3e for discharging water vapor or for eliminating the negative pressure in the container that is generated at the end of heating and when cooled in the refrigerator.

  By simply forming a valve mounting hole 2a in the lid body 2, the valve body 3 made of silicone or other heat-resistant soft material can be attached to and detached from the lid body 2 and has high heat resistance. If it is a container, it is very easy to transform it into a container that can be cooked by a microwave oven or other heating device by simply mounting the heating container valve A in the valve mounting hole 2a formed in the lid 2. Can be made.

  If the size of the valve mounting hole 2a to be formed in the lid 2 is the same, the size of the container body 1 and the size of the lid 2 to be put on the container body 1 will vary. There is also an advantage that the same size can be used.

  Also, the heat resistance temperature of the silicone material itself is about 230 ° C to 280 ° C, which is much higher than that of synthetic resin. If a valve made of silicone material is attached to the hole of a heat resistant glass or ceramic container, an oven is used. This valve also has a merit that it can be used for a long period of time because it does not undergo thermal deformation even when heated and is excellent in durability.

  Furthermore, since the silicone material is rich in flexibility, not only can the sealing / sealing property of the heating container B equipped with the heating container valve A be improved, but the heating container valve A can be extremely improved from the lid 2. Since it can be easily removed, there is an advantage that the heating container valve A and the lid 2 can be easily washed.

On the other hand, as described above, the heating container B suitable for heating food by a microwave oven or other heating device includes at least a heat-resistant container body 1 and a lid 2 that covers the container body 1. And the hole 2a for valve attachment is formed in the said cover 2, The negative pressure in the container which generate | occur | produces at the time of completion | finish of heating and cooling for the discharge of pressurized air and excessive steam in this hole 2a A valve body 3 made of a silicone material having a hole 3e for eliminating the above is attached, and a plug body 4 made of the same silicone material is connected to the valve body 3.
Then, when the connecting portion is folded in half by the hinge portion 5 formed between the connecting portion 3f on the valve body 3 side and the connecting portion 4a on the plug body 4 side, the hole 3e of the valve body 3 is connected to the plug body. 4 can be closed by the protrusion 4c provided on the head 4.

  According to the heating container B exemplified here, the hole 2a for attaching the valve body is formed in advance in the lid body 2 to be put on the container body 1 at the time of molding by the mold, or the hole 2a is not opened. A hole 2a for attaching a valve body is opened in the lid 2 later, and the heating container valve A can be easily attached to the hole 2a later. It is very easy to upgrade to a container that can be cooked with a heating device such as a range.

In addition, the mold cost for molding the valve A made of silicone material is very inexpensive, and the mold for molding the lid 2 for mounting the valve A simply opens a hole in the lid 2. Therefore, the cost merit in forming variations of the heating container having variously different shapes and sizes of the container body 1 and the lid 2 covering the container body 1 is extremely great.
In addition, since the valve body 3 is detachable from the lid body 2 and is not integral, the structure of the mold is not complicated compared to the case where the valve body 3 and the lid body 2 are integrally molded. The bill is extremely inexpensive.

When the food contained in the container body 1 is heated, the stopper 4 is raised as shown in FIGS. 2 and 5 to open the protrusion 4c that has closed the hole 3e of the valve 3. . Then, the inside and outside of the container main body 1 can be actively communicated through the opened hole 3e.
And in this state, it puts into a microwave oven and other heaters, and heats it. When the food is heated, the pressure in the container body 1 rises, but this pressurized air and excess water vapor generated at that time are smoothly discharged from the open hole 3e. In addition, when the internal pressure becomes low when the heating is finished or when it is cooled in the refrigerator and the lid 2 is stuck to the container main body 1 and cannot be removed, if the closed valve body 3 is opened, the inside of the container main body 1 is opened. Since the generated negative pressure can be eliminated by the hole 3e, the lid body 2 can be easily removed.

  2 and 5, the connecting portion is bent through the hinge portion 5 so that the connecting portion 4 a overlaps the connecting portion 3 f, and as shown in FIGS. 2 and 6, as shown in FIGS. When the protrusion 4c of the plug body 4 connected to the valve body 3 is pushed into 3e, the protrusion 4c closes the hole 3e of the valve body 3, so that the heating container B can be sealed. It can be used in the same way as a closed container.

  The valve body 3, the plug body 4, and the protrusion 4c formed on the plug body 4 are all made of silicone. Therefore, in combination with the flexibility and adhesiveness of the material itself, the valve body 3 is on the lid body 2. In particular, the ring-shaped groove 3d surface on the upper 3a side of the valve body 3 is on the upper surface of the lid body 2. Further, the ring-shaped groove 3d surface on the projecting portion 3c side of the valve body 3 is in close contact with the lower surface of the lid body 2, and the projecting portion 4c of the plug body 4 is in close contact with the hole 3e of the valve body 3. Since the hole 3e is closed on the airtight side, the sealing and sealing properties of the container B are further improved.

  And the connection part 3f which connects the valve body 3 and the plug body 4, the connection part 4a, and the hinge part 5 located between both are also made from silicone. Therefore, the valve body 3 and the plug body 4 including these can be formed very easily by integral molding.

As described above, when the connecting portion is bent via the hinge portion 5 so that the connecting portion 4a on the plug body 4 side overlaps the connecting portion 3f on the valve body 3 side, the upper portion 3a of the valve body 3 is formed. The connecting portion 4a on the plug body 4 side is fitted into the recess 3g, and the stepped flat surface portion 4b formed on the plug body 4 is fitted into the recess 3b formed on the upper portion 3a of the valve body 3. Get stuck.
Therefore, the sealing property and sealing property of the container B can be further improved.

In the heating container B illustrated here, as shown in FIG. 7, it is placed at a facing position in the peripheral part of the container body 1, here at a facing position on the short side of the heating container B or the container body 1. As shown in FIGS. 8 (a) to 8 (c), the handle 1 a, 1 a extending in the direction is protruded, and the peripheral portion on the short side of the lid body 2 that covers the container body 1 is The hinge locks 6 and 6 that can be bent at the connecting portion 6a with the lid body 2 are formed at positions facing the hands 1a and 1a, and the container body 1 is covered with the lid body 2 so that both the hinge locks 6 and 6 are attached. As shown in FIG. 9 (a), the handles 1a and 1a are fitted into the formed holes 6b and 6b, respectively, and the lid 2 can be locked to the container main body 1 with both hinge locks 6 and 6. .
In this case, even when both the hinge locks 6 and 6 are released and the lid body 2 is opened, the container can be used using the two handles 1a and 1a extending in the lateral direction from the container body 1. The food in the main body 1 can be carried with bare hands while the food is hot.

  In addition, here, a case where hinge locks 7 and 7 that can be bent at the connecting portions 7a and 7a are formed at opposing positions in the peripheral portion on the long side of the lid 2 is illustrated. Both hinge locks 7 and 7 are formed with engaging claws 7 b and 7 b extending inward, and both engaging claws 7 b and 7 b are formed at the peripheral portion of the container body 1. The lid body 2 can be locked to the container main body 1 by engaging with the container body 1.

  Further, here, a concave groove is formed over the entire circumference on the back surface of the peripheral edge portion of the lid 2, and as shown in FIG. 9, an elastic cross-section tubular packing 8 is inserted into the concave groove. It is. Therefore, when the lid 2 is put on the container body 1 and the lid 2 is locked by the hinge locks 6 and 6 and the hinge locks 7 and 7, the cylindrical packing 8 is deformed as shown in FIG. It is press-contacted to the peripheral part of the main body 1, and the sealing property of the container main body 1 and a sealing performance further improve.

  Here, the case where the container main body 1 and the lid body 2 covering the container main body 1 are rectangular is illustrated, but the present invention is naturally applicable to a round shape or a bowl shape.

  As shown by reference numeral 4d in FIGS. 1 to 3, if a knob is formed at the tip of the plug body 4, it is convenient because the plug body 4 can be opened by picking the knob 4d.

  If the container body 1 and the lid body 2 are made transparent, the food in the container body 1 can be seen through without opening the lid body 2. Is also very convenient.
