Description

Detailed Description of the Invention

In the present invention, cooking and leftovers made in a pan are sterilized by heating, and after the fire has been turned off, the lid is put on and initially adsorbed, and then the natural pressure reduction due to the temperature drop is used as it is. The present invention relates to a pan-size free-size vacuum lid that can be stored in a pan.

Conventionally, when you want to eat dishes and leftovers made in a pan after half a day or after the next day, it is usually stored in a pan or stored in a refrigerator etc. after transferring to another container. It is a simple method. The former method is possible in the winter when the temperature is low, but in summer when the temperature is high or in the kitchen where the room temperature is always high, the dishes inside are damaged in a short time. (Patent Document 1) A lid for a container has been proposed.
Further, in the latter method, the following (Patent Document 2) using a reduced pressure only by pressing as a means for improving the storage stability, the following (Patent Document 3) food or the like using a suction tool to reduce the pressure. A sealing lid member for a storage container has been proposed.
Special table 2002-536249 Actual Application 2000-1671 JP 2001-46234 A

(Patent Document 1) states that the dedicated use pan can be directly sealed under reduced pressure, but the configuration is such that the lid is integrally formed with a seal clip so that the periphery functions as a gasket on the use pan or container of unknown material, It is said that the airtightness in the pan is maintained. However, in this structure, if there is a slight scratch or deformation in the pot mouth, the outside air will flow in and the pressure will not be reduced, and if you use a plastic lid while cooking, Since the temperature becomes high, the seal part is deformed or melted by high heat, and this is a practically almost impossible proposal.

(Patent Document 2), when the lid is pressed by hand and sealed, the pressure of the air is very small because of this, and the decompression force is very weak, and when the dish is transferred to this container, Even if it is stored in a weakly decompressed state after being exposed to water, mold and bacteria mixed in the container with the food are easy to propagate inside, and even if it is refrigerated, it is not very suitable for long-term storage.
(Patent Document 3) is effective for long-term storage because it can be strongly decompressed with a suction tool, but for example, to preserve dishes made in a pan, mold and bacteria are also transferred when transferred to a container as described above. Mixing and complete sterilization of the container itself is also very difficult.
In addition, the documents 2 and 3 are troublesome and time for transferring from the pan to the dedicated container, and cannot be put in the refrigerator until it is further cooled. In addition, a considerable amount of space is required in the refrigerator, and the energy to cool and this cooling. In order to eat the cooked food again, it is still consumed in large quantities, such as moving to a pot and reheating it. And the proposed appliances of the above three examples cannot be used unless the relationship between the pan, the container and the lid is always the same size, and there is no compatibility with other calibers and there are restrictions on the use. It was inconvenient.

Currently, in order to store the pan in a pan, keep it heated for a long time with low heat, or repeat the heat sterilization several times every few hours, or put it in the refrigerator directly in the pan. In addition to ordinary households, a large amount of energy is wasted not only in ordinary homes, but also in restaurants and restaurants that make dishes at once.
And even if the power outage is prolonged due to natural disasters such as earthquakes and typhoons, and even when cooking outdoors or camping, there is no appropriate preservation method of dishes made with pots, and global warming is now being screamed, This trend is increasing at present.

In the present invention, the lid body has a shallow dish-shaped double structure, a durable base material on the upper surface, heat-resistant silicone rubber suitable for adsorbing to the pan mouth on the lower surface, and a pan with a different caliber on the lower surface. A wide suction surface is formed so as to be compatible, and a pressing portion is provided at the center of the main body so that hot air in the pan is pushed out to facilitate initial suction.

According to the present invention, any pan having a diameter within the range of the maximum and minimum diameters of the suction surface on the lower surface of the main body can be used. Even if the tip of the pan grip part is higher than the pan mouth surface, the lid can be adsorbed without being disturbed. And the use of the inside of the pan is sufficiently heat sterilized, and after stopping the fire, if the lid of the present invention is put on and pushed down from above, the air inside will be pushed out by that amount, so the initial adsorption is easy and It can be done quickly and can be securely attached to the pot mouth.
For example, if the lid is left on without being pressed, even if the pan changes from thermal expansion to contraction, the initial contraction force and contraction amount are minimal and very small. The inflow of outside air from the pot mouth cannot be prevented, and no matter how much time elapses, the lid will not be in close contact with the initial adsorption and will fail.

The lid of the present invention can complete the initial adsorption when the inside of the pan is at a high temperature of about 90 ° to 95 ° C. Therefore, the adsorption surface that contacts the hot air in the pan and the inner surface of the pressing portion are almost completely the same as the inner dish. It can be sterilized, and after adsorbing, it is not necessary to do anything, and the adsorbing state can be easily confirmed by just looking at the dents in the entire pressing part, and the heat in the pan decreases. The suction force is increased by gradually increasing the decompression force due to the contraction, and the maximum suction force due to the decompression is when it is lowered to room temperature. And until it reaches room temperature after heat sterilization, and after that, no outside air will flow into the pan, and it is effective similar to bottled preservation by suppressing bacteria and oxidation by very strong decompression It can be stored at room temperature. The lid opening method is a method of making a slight gap in a part of the pan mouth by deforming part of the outer periphery by hand, or a method of opening a part of the valve body provided in the center with a fingertip. Thus, the lid can be easily removed if the decompression is released by flowing in the outside air.

Hereinafter, it demonstrates in order based on the Example of this invention.
FIG. 1 shows a first embodiment of the present invention (Claim 2), wherein the base material 2 of the lid 1 body is made of polyethylene and the cross-sectional shape is formed in a corrugated shape. The height and the number thereof may be arbitrary, and the shape may be a trapezoidal shape continuously connected as shown in FIG. One to three reinforcing plates 3 projecting upward are provided on the upper surface of the outer periphery of the main body, and a peripheral stopper portion 4 opened obliquely downward is provided on the lower surface. And in the center of the base material 2, an inverted saddle-shaped pressing part 6 having a knob part 5 formed integrally with the upper part is provided. The base material 2 formed in this way has at least one reinforcing plate 3 on the outer periphery, a lower peripheral stopper portion 4, and the entire lower surface of the base material 2 with an appropriate thickness and stretch. Covered with silicon rubber 7 with a relatively low rate.

The forming method is a method of fitting in a shape opposite to each other, or making the entire silicon rubber 7 slightly small and forcibly fitting it to the base material 2 to use the tensile force, friction and adsorption of the rubber. 2 or a method of fixing with a dedicated adhesive, a method of pouring one of the materials into a mold and bonding or welding them later, or as shown in FIG. Is a method in which a plurality of small holes 8 are provided on a concentric circle, and a locking piece 9 that can lock the tip is provided on the upper surface of the silicone rubber 7 and is fixed through the small holes 8 or B. As shown in the figure, a locking wall 10 connected concentrically is projected downward on the bottom surface of the corrugation, and a concave groove 11 is formed on the upper surface side of the silicon rubber 7 to fit with each other, or the bonding or welding described above. To stick together It may be any fixing method.

The surface of the silicon rubber 7 on the lower surface of the main body configured as described above has a suction surface 12 corresponding to the pan mouth as a mirror finish, and a peripheral edge having a width of about 1 to 2 centimeters left so that a fingertip can be hung on the outer peripheral surface. A space portion 13 is provided. The peripheral space portion 13 has a rough surface, or a plurality of protruding or groove-like step portions 14 extending radially from the center of the body to the surface so as to prevent the pot mouth from adsorbing. is there.
The usage method of the first embodiment will be described. First, a pan lid is put on a pan containing dishes, and the heat is sterilized sufficiently at 95 to 100 degrees, and then the fire is stopped. After about 5 minutes, the pan lid is removed and the lid 1 of the present invention is placed instead. At this time, there is no problem even if the lid 1 is slightly deviated from the center of the pot mouth, but the center position is adjusted as much as possible. Next, the center knob portion 5 is held with one hand, and the pressing portion 6 is pushed down from above. Then, the corrugated polyethylene base material 2 is dented in the center together with the silicon rubber 7 on the lower surface, and then the periphery thereof is slightly extended to slightly deepen the dish shape. Thereby, the hot air in the pan is pushed out from a part of the adsorption surface 12. And by releasing the hand after this, a weak decompression state is created in the pan by the restoring force that the main body and the pressing portion 6 try to return before deformation, and the suction surface 12 is weakly attracted to the pan mouth and is initially Adsorbed.

The operation is completed as described above, and it is only necessary to leave it as it is. However, if the pan is moved immediately after the completion of the initial adsorption, a re-boiling phenomenon occurs at a high temperature of 95 degrees or more, and the internal pressure increases. Therefore, it is necessary not to move for at least 10 minutes.
The temperature of the left pan gradually decreases with time, and the expanded air in the pan gradually contracts, the decompression force gradually increases, the adsorption force increases, and the entire lid 1 becomes a deep dish shape. Become.
The adsorption force is greatest when the temperature drops to room temperature, and a very strong decompression force and adsorption force can be obtained. After half a day to several days, if the center is dented and deep, it means that the outside air has not flowed in, so it is easy to confirm the success or failure of adsorption holding.

Next, the lid 1 is opened by using the right hand to place the fingertip on the inner side of the reinforcing plate 3 on the upper surface using the right hand and hook the remaining two to four fingertips on the peripheral space portion 13 on the lower surface. It is only necessary to rotate counterclockwise with the thumb as a fulcrum, and only a part of the suction surface 12 is deformed. Therefore, it is possible to easily create a gap and allow the outside air to flow in, and the decompression is released. At that time, the lid 1 can be removed. Since the main body is dish-shaped, it is easier to turn to the center side with a lighter force than when it is flat or inverted (dome-shaped). In addition, even if a lateral shift occurs, the pot opening is suppressed by the peripheral space portion 13. And since an adsorption | suction location touches not the upper end of a pot opening but the inner peripheral surface side slightly, a frictional force generate | occur | produces and initial adsorption | suction can be performed with a weak decompression force rather than the shape of the said 2 examples. In addition, since the peripheral space portion 13 provided on the lower surface of the outer periphery in this embodiment is a space necessary at the time of opening, it is ensured that the space is not adsorbed to a caliber pan having a specified dimension or more with respect to the lid 1. Can be secured.

FIG. 3 shows a second embodiment (Claim 3), wherein the base material 2 is made of polypropylene, and an opening 15 having a circular shape with an inner diameter of about 5 to 15 cm, preferably about 12 cm, is provided at the center. It is provided. This illustrates the case where the outer diameter of the lid 1 is about 26 centimeters, but if the outer diameter is larger than this, the inner diameter may be increased accordingly.
Around the opening 15, there is provided a reinforcing wall 16 facing upward and having a bulging or keyed cross-sectional shape at the tip. Further, the silicon rubber 7 continues from the reinforcing plate 3 of the base material 2 to the lower surface, and further upwards in the opening 15. It is protruded to.
The inner space of the pressing portion 6 is larger than that of the first embodiment, and the outer peripheral portion at the lower end of the pressing portion 6 is stopped so as to wrap the reinforcing wall 16. Note that a metal or plastic ring-shaped member 17 may be fitted on the outer peripheral surface as necessary, and the lower end may be tightened, or may be fixed using a dedicated adhesive. Moreover, you may make it attach to the said knob part 5 by the method of screwing in or pushing in the plastic cap with a collar (not shown) etc. which assists a grip from the top.

In addition, although the said press part 6 illustrated the state formed integrally with the silicon rubber 7 in a lower surface, as shown in FIG. 4, the press part 6 whole is formed independently, and the lower end is formed in the silicon rubber 7 of a lower surface. It is also possible to fit the reinforcing wall 16 whose one end is locked, and finally tighten the outer periphery with the ring-shaped member 17. In this case, the pressing part 6 uses properties (elongation rate and hardness) and materials (natural rubber, heat-resistant urethane rubber, chloroprene rubber, other heat-resistant elastic materials) different from the silicon material used for the adsorption surface 12, It is possible to replace only the pressing portion, which is very advantageous compared to the integrated type because it is easy to use and change.
The reinforcing plate 3 and the peripheral stopper portion 4 of the base material 2 provided on the outer periphery of the main body, the peripheral space portion 13 on the outer periphery of the suction surface 12 and the like are provided in substantially the same manner as in the first embodiment. Yes, the operation method is the same, but since the base material 2 of the second embodiment uses a material with little deformation even under strong decompression, the vertical movement of the pressing part 6 can be made to react sensitively. It is possible to know the decompression state in more detail.

C of FIG. 5 shows a third embodiment (Claim 4), in which a knob with a valve is provided at the knob portion, and a through hole 18 penetrating to the lower surface of the pressing portion 6 is provided at the center of the knob portion 5. It is. A projecting ring 19 having a circular shape and a mountain-like cross section is provided on the upper surface of the knob portion 5, and a concave guide groove 21 that helps the initial inflow of outside air from the projecting ring 19 on the vent 20 side to the through hole 18 is provided. The valve body 22 made of a plate-like silicon rubber or an elastomer resin is placed thereon, and the upper part of the through hole 18 is cold. This state is maintained, and a protective cap 23 is attached to the upper portion of the valve body 22 from above, leaving a slight gap. The protective cap 23 is made of a bendable material such as polypropylene, and a front surface of the vent hole 20 has a peripheral surface plate 24 whose lower portion is opened obliquely, and an upper surface that has a folding plate 25 that can be raised upward. A confirmation window 27 for viewing the valve element 22 from above is provided at the center of the top plate 26.

The protective cap 23 is attached by using the elasticity of the knob 5 to fix the cap inner surface in close contact with the peripheral surface, or by providing a protrusion 28 in the middle of the peripheral surface and hooking the cap inner surface on this. It may be fixed. In addition, although it may be fixed by screwing with a screw thread, in this case, it is preferable to provide a plurality of the guide grooves 21 radially from the through hole 18.
Further, as shown in FIG. 5D, the shape of the valve body 22 is a metal or plastic sphere, which is placed directly on the upper surface opening of the through hole 18 to close the hole, and on the lower surface of the bent plate 25. A vertical plate 29 extending downward from the fold portion is projected near the sphere, and the top plate 26 is provided with a step 30 that suppresses the movement of the sphere within a certain range, and the protective cap 23 is formed by a screw thread 31. It is fixed by screwing.

As described above, the operation method of the valve cap shown in FIG. 5C in the third embodiment holds the protective cap 23 in the same manner as a general method of gripping the lid, and pushes down the pressing portion 6 as it is. Then, the hot air in the pan pushes up the valve body 22 through the through-hole 18, passes through the vent 20 of the cap from the gap with the protruding ring 19, and a part is blocked by the peripheral plate 24, and the arrow opens from the open part below. Discharged in the direction. At this time, the gripped hand is guarded from heat by the peripheral surface plate 24 in front of the vent hole 20 and the inner side of the hand is guarded by hot air by the bent plate 25 located above, so that safety is ensured.
Next, when the pressed hand is released, the valve body 22 is instantaneously drawn downward by the restoring force of the pressing portion 6 to prevent the inflow of outside air. At the same time, the lower surface of the valve body 22 is surrounded by the projecting ring 19 and the center. Is attracted to the upper surface of the through-hole 18 and is adsorbed in a dent-like state as a whole. At this time, the pressing portion 6 returns slightly, but stops in a state close to when it is almost pressed. In addition, when there are a lot of large and deep pots and dishes in a small space, or when it is too hot and does not turn into shrinkage, the extrusion ratio will be reduced quantitatively, so the pressing part will be more than the pressure reducing force in the adsorbed pot. In some cases, the restoring force of 6 is stronger, and it almost returns to its original shape. At first glance, external air may flow in and it may appear as if adsorption has failed. However, since the plate-like valve element 22 of this embodiment reacts sensitively to a very weak decompression force and shows an adsorbing state, the initial adsorbing can be seen by looking at the dent of the valve element 22 from the confirmation window 27 on the upper surface of the cap. It is very convenient, and if it is left as it is, it can be visually observed that the pressing part 6 starts to dent slowly after 5 to 10 minutes. When it is, it may be re-adsorbed by pressing again.

Next, the release method is that the bent plate 25 at the tip of the top plate 26 of the cap is raised with an index finger, then the fingertip is inserted as it is, and one end of the valve body 22 is caused to rise upward from below, By creating a gap up to the through hole 18, the outside air flows from the vent hole 20 through the through hole 18 into the pan, and the decompressed state is released. At this time, if there is a guide groove 21, the outside air is instantly guided to the through hole 18 only by creating a gap only in the protruding ring 19, so that the triggering operation can be quickly released with a lighter force than the above.
Further, in the spherical valve body 22 shown in FIG. 5D, when the tip of the bent plate 25 is pushed downward with a fingertip, the valve body 22 is pushed to the lower end of the lower vertical plate 29 and slightly rearward. The outside air flows into the through hole 18 from the front side and the decompression is released. When the valve is spherical, the deformation of the valve itself cannot be confirmed as in the case of the plate shape, but other operation methods and effects are almost the same.

FIG. 6 shows a fourth embodiment (Claim 5), and the entire outer surface of the pressing portion 6 is provided with a metal or plastic spiral member 32, the upper end of which is the entire circumference of the lower end of the knob portion 5. It is firmly clamped and fixed in the recess 33 provided in the. Further, as shown in FIG. 4, the bullet body 32 may be mounted so as to be in contact with the inner surface of the pressing portion 6. The elastic body 32 may be provided as necessary when the repulsive force or restoring force cannot be sufficiently obtained due to the shape, material, thickness, etc. of the pressing portion 6 itself. It may be a method of enclosing within the cross section of the pressing portion 6.

A fifth embodiment (Claim 6) is shown in FIG. 1, and a plate-like protruding piece 35 having a finger hole 34 is formed on the upper end of the innermost reinforcing plate 3 provided on the outer periphery of the base material 2. It protrudes upward via the folding part 36. Further, the projecting piece 35 shown in FIG. 3 projects two parallel plates 38 each having a shaft hole 37 on the upper surface of the base material 2 near the reinforcing plate 3, and the projecting piece 35 is provided with shafts for the holes on both sides of the lower end. Is attached to the parallel plate 38.
In the use of the above two examples, when the lid 1 is initially attracted, the fingertip of the left hand is hooked into the finger hole 34 of the projecting piece 35 while the pressing portion 6 is pressed down with the right hand, and the inner pressure is released slightly. Release the left hand and then the right hand afterwards. As a result, it is possible to completely remove the applied pressure in the pan that has been slightly left only by pressing, and the initial suction is easier and the suction force can be increased than when this operation is not performed. Further, the projecting piece 35 can also be used for hanging on a nail, a hook or the like when the lid 1 is stored.

FIG. 7 shows a sixth embodiment (Claim 7). On the surface of the base material 2, mark lines 39 are provided at equal intervals on a concentric circle from the center side to the outer peripheral direction. The method may be a protruding line that is stronger than the groove shape, and its thickness and height may be arbitrary, and the used dimensions and notes of the pot mouth may be written on a part of the line. When the mark line 39 is provided, if the main body material is made transparent, the cover line 1 is placed so that the mark line 39 on the upper surface and the pot mouth seen through below overlap on the concentric circles when placing. It can be set almost at the center.

FIG. 8 shows a reduced pressure state at room temperature in the use of the third embodiment, and the pan 40 shows the use of the maximum diameter (the broken line is the minimum diameter) with respect to the lid 1. When the temperature in the pan reaches room temperature, the maximum decompression force and adsorption force are obtained, and the lower surface of the main body is strongly attracted to the pan mouth, and as it is, it is strongly adsorbed so that it cannot be easily removed even by the power of an adult. Yes. Further, in this state, the maximum pan mouth is located on the outermost periphery of the suction surface 12, but even when the maximum suction force is reached, the peripheral stopper 4 prevents the slipping off, and the stop state is firmly secured. Maintained.
Moreover, since the top of the cap is lower than the outer periphery of the main body during storage under reduced pressure, it is convenient when stored in a shelf or a cabinet. In the case of the unsealing method using a valve, since it is not necessary to deform the main body as in the first and second embodiments, the base material 1 can be made of heat-resistant glass or metal only in the valve method.
According to the present invention, as long as there is no deep scratch or strong deformation in the pan mouth and there is no gap in the fixed rivet of the handle, it can be used for any pan as long as it is within the range of use. Energy savings, significant savings in labor and time, and providing a free-size decompression lid for pans that is extremely effective and convenient in times of natural disasters such as earthquakes and typhoons, and in areas and countries where there is no electricity or outdoors can do.
