TECHNICAL FIELD OF THE INVENTION
The present invention relates to a container for storing and storing various contents, and more particularly, to a container in which contents are stored without opening the lid, the container can be immediately heated in a microwave oven, and the lid can be easily opened and airtight. The present invention relates to an airtight container that is effective.
[0002]
[Prior art]
Generally, closed containers are used to store various foods such as side dishes, vegetables, fruits, fish, and the like, and such closed containers for storing foods and drinks are open at the top as shown in FIG. And a lid for covering the entrance of the container main body, wherein the container main body and the lid are formed in various shapes such as circular or square (for example, Patent Documents 1 and 2). ).
[0003]
In a recent closed container for a refrigerator having such a structure, the lid for covering the container main body has a function of merely covering the container main body, and further, the content is shielded from the outside air to prevent deterioration of the content. In order to store food and drink in the container for a longer period of time, locking means for completely engaging the upper and lower portions of the container with a packing material such as natural rubber or silicone rubber are also provided around the inner circumference of the lid. ing.

[Patent Document 2]
JP-A-11-43163 (page 2-3, FIG. 5)
[0005]
[Problems to be solved by the invention]
However, in such a closed container for storing foods and drinks, as shown in FIGS. 8 and 9, several lids are attached to the lid 20 of the container body 10 having a uniform outer skin thickness (D = d). Unlike the intermediate portion engaged by the engagement means even when the engagement means is provided, there is no engagement means at both ends of the edge between the end of the container body 10 and the packing material 30 of the lid 20. Has a slight gap (l). Therefore, when the closed container is tilted or covered during storage or carrying, the juice may leak to the outside through a loose gap between the container body 10 and the lid 20 at a portion where there is no engaging means. This phenomenon is more serious when the size of the sealed container is large, especially if the kimchi and other Korean foods have a lot of juices and drinks. It provides a cause for food and drink to be easily degraded by the passage of air.
[0006]
Moreover, as described above, food and drink storage containers made of packing materials are heated in a microwave oven with the lid closed, and there is a danger of explosion due to air expansion. When heating the container, be sure to open the lid and wrap the container body with a separate kitchen wrap, then put it in a microwave oven with a few holes in the wrap and heat it. There was a problem.
[0007]
Further, as described above, conventionally, since the food was heated by putting the container body in a microwave oven with the lid removed, the electromagnetic wave came into direct contact with the food at the time of heating, so there was also an uneasy problem. .
[0008]
In addition, in the conventional closed container for food storage, when the lid is closed, the inside of the container body is sealed with a packing material such as silicon and almost in a vacuum state, so that the food in the container body is taken out. When the lid was opened, there was also a problem that the lid could not be easily opened due to the vacuum suction input inside the container body.
[0009]
So, we have been working on multiple angles to develop a sealed container that can completely solve these disadvantages, but until now the lid was covered and sealed with perfect sealing effect The fact is that a container that can be heated immediately even in the state cannot be manufactured at a low unit price.
[0010]
The main object of the present invention was invented in order to solve the conventional disadvantages as described above, and by changing the structure of the lid, it can be completely airtight in a low-cost but simple manner, An object of the present invention is to provide a closed container in which the contents can be conveniently heated by immediately placing the contents in a microwave oven with the lid closed.
[0011]
Another object of the present invention is to provide a closed container that allows the lid to be easily opened by allowing external air to flow into the container body when the lid is opened.
[0012]
[Means for Solving the Problems]
In order to achieve the above object, a closed container according to the present invention has a lever groove in which a ventilation hole is vertically penetrated in a lid, and a lever provided with a protrusion fitted into the ventilation hole of the lever groove is rotatable. The assembling is performed by mounting a packing for hermetically sealing the ventilation hole on the protruding rod.
[0013]
Further, in the present invention, in the closed container for achieving the above object, the container is inclined or covered by a certain impact so that the edge of the container body and the edge of the lid are more securely pressed and adhered. Even if the juice in the container does not leak to the outside, the airtight effect is assured, and the lid can be opened and closed during use to absorb oxygen from the air remaining in the container, so that Manufactured practically to prevent it.
[0014]
ADVANTAGE OF THE INVENTION According to this invention, the container main body which accommodates food and drink, the cover which covers the entrance of a container main body, and is provided with the coupling groove in the whole edge, It is attached to a lid | cover and air-tightly seals the entrance of a container main body, and the said coupling groove In a closed container composed of a packing material inserted into the container, a locking protrusion protruding on both sides of the container body, a handle rotatably installed on both sides of the lid and detachably fixed to the locking protrusion,
A lever groove formed in an upper portion of the lid and recessed into a lower portion; a lever rotatably mounted on the upper and lower sides of the lever groove; a boss formed in the lever groove and projecting to a lower portion; and an inner diameter of the boss. A protrusion protruding downward from the lever and fitted into the vent; and a packing mounted on an outer diameter of the protrusion to hermetically seal the vent.
[0015]
The thickness of the coupling groove formed at the edge of the lid may be gradually increased from the center of one side to both ends.
[0016]
In the closed container according to the present invention, the container body is made of stainless steel or a polyolefin-based resin such as polypropylene (PP) or polyethylene (PE), or a synthetic resin such as polyethylene terephthalate (PET) or polycarbonate (PC), similarly to a conventional container. The material is appropriately selected from the above, and is integrally formed by a normal method such as injection or extrusion molding or a mold depending on the selected material. When made of stainless steel, no endocrine disruptors are generated, but the price is somewhat expensive and somewhat heavy.When made of polyolefin resin, the price is low, but there are advantages. There is a disadvantage that the surface of the container is apt to be scratched because it is easily damaged. On the other hand, in the case of polycarbonate, it is clear that there is no such disadvantages, the impact is strong, the flaws are not easily generated, and it is transparent. It has recently consisted of polyethylene terephthalate alone or a suitable mixture thereof, which is somewhat expensive, but without the release of environmental hormones, depending on consumer preference for luxury products. When the lid is also made of the above-mentioned material and is mainly made of stainless steel, only the edge is formed of a component different from that of the main body, for example, a synthetic resin, so that the sealing degree can be further enhanced. It may be something.
[0017]
The packing material to be inserted into the coupling groove of the lid is not particularly limited, and suitable examples include a resin or rubber having closed cells.Examples include polyethylene, ethylene-vinyl acetoate copolymer, Foams such as polyolefins such as ethylene-propylene copolymer and polypropylene, polystyrene, vinyl chloride resin, polyurethane, styrene-butadiene rubber, and natural rubber are desirable. In addition, an elastomer (elastomer) made of natural rubber, butadiene rubber, styrene-butadiene rubber, nitrile-butadiene rubber, polyurethane, butyl rubber, ethylene-propylene rubber, soft vinyl chloride resin, or the like is also applicable.
[0018]
Further, when the packing material in the present invention contains an oxygen absorbent, it can absorb the oxygen in the container together with the sealing effect and further improve the preservability of the contents, so that the ordinary reducing iron can be used. Reducing metal powder such as zinc, reducing zinc, ferrous oxide, low metal oxide such as 4,3 iron oxide, reducing metal compound or polyhydric phenol-containing polymer compound, etc., alone or in combination Can be done.
[0019]
The thickness of the coupling groove formed on the edge of the lid must be in the range of 0.3 mm to 3 mm between the end thickness of the non-engagement portion and the center thickness of the engagement portion. If the difference in thickness is too large, the packing material inserted into the end of the lid requires a large amount of force to adhere under pressure as it is more protruded to the outside, and if the difference in thickness is too small, the adhesion force Is weakened, so that the above range is desirable.
[0020]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the technical configuration of the present invention will be described in detail with reference to the accompanying drawings.
[0021]
First, as shown in FIGS. 1 to 3, a first specific example of the closed container for food and drink storage A of the present invention covers a container body 10 for storing contents, mainly food and drink, and an entrance of the container body 10. A lid 20 having a coupling groove 3 for inserting a packing material on an edge, a packing material 30 mounted on the lid 20 to hermetically seal an entrance of the container body 10, a locking projection 11 protruding on both sides of the container body 10, A lever groove 21 rotatably installed on both sides of the lid 20 and detachably fixed to the locking projection 11, formed on an upper portion of the lid 20 and recessed into the lower portion; A lever 50 rotatably mounted up and down, a boss 22 formed in the lever groove 21 and protruding downward, and a vent hole 23 formed in the inner diameter of the boss 22 and vertically penetrating, a lower portion of the lever 50 Protruding into the vent hole 23 Piercing rod 51 is fit, and includes a packing 60 for sealing the vent hole 23 hermetically mounted to the outer diameter of the projecting rod 51.
[0022]
Here, it should be noted that the container body 10 and the lid 20 are formed in various shapes such as a square or a circle as described above. That is, although the container body 10 and the lid 20 are formed in a rectangular shape for reference, the present invention is not limited to this as described above. It can be formed in various shapes such as a circle and an ellipse.
[0023]
The container body 10 and the lid 20 are substantially transparent so that the food and drink inside can be easily seen, and the container body 10 and the lid 20 can be placed in a microwave oven at a high temperature. As described above, it is made of a 100% non-toxic material, such as polyethylene terephthalate alone or an appropriate mixture thereof, which is usually used when making infant milk bottles so that no hormone is generated.
[0024]
The container main body 10 of the closed container A according to the present invention accommodates food and drink, and the upper entrance of such a container main body 10 is opened, and the lid 20 is inserted into the container main body 10 at the time of connection. An outer peripheral projection 4b located outside the container body 10 is provided at the edge thereof, and a coupling groove 3 is formed between them. Locking projections 11 project integrally on both sides of the container body 10, A large number of the locking projections 11 are provided on the front and rear and / or both right and left sides in accordance with the corresponding handle 40. The handle 40 may be engaged in the manner shown in FIGS. 1 and 8, or may be formed by other ordinary different engagement structures.
[0025]
The lid 20 covers the entrance of the container body 10, and a lever groove 21 is formed at an upper portion of the lid 20 so as to be recessed at an appropriate depth into a lower portion. The boss 22 is integrally formed, and a vent hole 23 communicating vertically is formed in the center of the boss 22.
[0026]
A shaft groove 21a is formed on one side inside the lever groove 21 and an insertion groove 24 is extended deeper on the opposite side of the lever groove 21 from the shaft groove 21a so that a finger can be fitted therein. Is done. At this time, the reason why the insertion groove 24 is formed is to allow the lever 50 to be more conveniently rotated and opened.
[0027]
The packing material 30 hermetically seals the entrance of the container body 10, and such a packing material 30 is mounted in the coupling groove 3 at the lower edge of the lid.
[0028]
The handles 40 are rotatably installed on both sides of the lid 20, and are detachably fixed to the both-side locking projections 11 of the container body 10.
[0029]
The lever 50 is rotatably assembled in the lever groove 21 to open and close the vent hole 23. A protruding rod 51 fitted into the vent hole 23 is integrally formed below the lever 50, and A shaft pin 50a rotatably fitted in the shaft groove 21a of the lever groove 21 protrudes on both sides of the lever 50, and a protrusion 52 located in the insertion groove 24 of the lever groove 21 protrudes on the side of the lever 50 opposite to the shaft pin 50a. I do.
[0030]
The packing 60 is attached to the protruding rod 51, and the packing 60 is airtightly adhered to the inner diameter of the air hole 23 to completely seal the air hole 23.
[0031]
The overall operation of the first embodiment of the present invention will be described in detail.
[0032]
First, as shown in FIG. 2A, when the lever 50 is rotated downward and pushed to close, the protruding bar 51 formed on the lower portion of the lever 50 is fitted into the ventilation hole 23, and the packing 60 mounted on the protruding bar 51 is released. In this state, the air hole 23 is closed so that air between the inside and the outside of the container main body 10 does not communicate with the inside of the container body 10 in order to hermetically close the air hole 23 while being tightly adhered to the inner diameter of the air hole 23.
[0033]
Next, as shown in FIG. 2 (b), when the lever 50 is rotated upward and opened, the protruding rod 51 is pulled out of the vent hole 23 while rotating integrally. The air holes 23 are opened so that air can pass.
[0034]
According to the present invention, as shown in FIG. 2B, when the lever 50 provided on the lid 20 is opened to open the vent hole 23, the pressure in the container body 10 is discharged to the outside through the vent hole 23. In addition, there is an advantage that even if the lever 50 is easily opened without opening the lid 20, the food can be conveniently put into the microwave oven and the food can be conveniently heated.
[0035]
In addition, the sealed container A according to the present invention can be put in a microwave oven with the lid 20 closed to heat food and drink, so that the electronic wave does not directly touch the food and drink during cooking, so that it can be used with confidence. There is also an advantage that can be.
[0036]
In addition, in the present invention, when the lid 20 is opened, as shown in FIG. 2B, when the lever 50 is opened, the external air flows into the container main body 10 through the vent hole 23 and the vacuum state in the container main body 10 is released. There is an advantage that the lid 20 can be easily opened.
[0037]
In the present invention, since the container body 10 and the lid 20 are made of a transparent body, there is a merit that the food and drink inside can be easily seen. In particular, since the container body 10 and the lid 20 are made of a non-toxic material, the microwave oven is used. There is an advantage that environmental hormones are not generated at all even if it is put and heated at a high temperature.
[0038]
On the other hand, when the lid 20 is closed, as shown in FIG. 2, when the lever 50 is pressed and closed to close the ventilation hole 23, the outside air is prevented from flowing into the container body 10, so that the container body 10 is airtightly closed. Can be sealed.
[0039]
Further, according to the closed container A of the second specific example according to the present invention, as shown in FIGS. 7, 6 (a) and 6 (b), the coupling groove 3 is formed at one side edge of the lid 2. It is formed so that the thickness at the center 9a where the locking protrusion 11 is located is the thinnest and gradually increases toward the end 9b. That is, the thickness of the center 9a of the engagement portion a and the end 9b of the non-engagement portion b in the coupling groove 3 at the edge of the lid 20 differ by 0.3 mm to 3 mm in consideration of the pressing force and the adhesion force. Is formed.
[0040]
As shown in FIG. 6 (a), a packing material 30 having an appropriate thickness is inserted around the entire periphery of the coupling groove 3 of the lid 20 formed as described above.
[0041]
The lid 20 thus formed is positioned on the container body 10 containing the contents, and a predetermined force is applied to the entire lid 20 so that the handle 40 is locked by the locking projection 11 of the container body 10. When pressed, the packing material 30 at the engagement portion a of the lid 20 is loosely pressed against the packing material 30 at the non-engagement portion b, and the packing material thickness X of the engagement portion a becomes the non-engagement portion. It becomes thicker than the packing material thickness Y at the b end 9b.
[0042]
This is because the thickness of the coupling groove 3 at the end of the coupling groove 3 at the edge of the lid 20 is larger at the end than at the center 9a even if the pressing force acts in the same manner, so that the packing material at the end 9b of the non-engagement portion b is more. By protruding outside, it is more strongly pressed against the end 6 of the container body 10 and the bulk thereof is further reduced (see FIGS. 4, 6 (a) and 6 (b)).
[0043]
Therefore, the container body 10 and the lid 20 can be connected to each other in a completely air-tight state as much as possible. In this case, when the packing material 30 contains an oxygen absorbent, the container body 10 and the lid 20 may infiltrate during the connection. Since the absorbed oxygen can be absorbed, the contents in the closed container A can be stored for a long time.
[0044]
Even when the closed container A according to the present invention has a cylindrical shape, the thickness of the coupling groove 3 increases toward the both ends 9b of the edge of the lid 2 based on the center 9a of each handle 40 of the edge of the lid 2 as described above. With this configuration, the packing material 30 at the end 9b of the packing material 30 bonded to the coupling groove 3 is pressed more when the pressure is applied to the end 6 of the container body 10. This allows the container to be kept completely airtight overall without small gaps.
[0045]
【The invention's effect】
As discussed above, according to the present invention, the contents can be conveniently heated by immediately placing the contents in a microwave oven without opening the lid, and when the lid is opened, external air is generated inside the container body. This is a very useful invention that can be used with ease because the lid can be easily opened because it flows in and the electronic wave does not directly touch food and drink.
[0046]
In addition, according to the closed container of the present invention, since no gap is formed between the container body and the lid, the juice does not leak even when edible food such as kimchi is stored. Is convenient, and since the oxygen in the container can be absorbed, the food can be reliably maintained in an airtight state, so that the storage period of the food can be extended.
[0047]
Further, since the closed container according to the present invention is easy to manufacture, it can be manufactured at a low unit price, and has excellent durability and is very economical.
