Description

  The present invention relates to a storage container, and more particularly to a storage container with a check valve capable of maintaining the inside of a container body in a low pressure state or a state in which the amount of remaining air is small.

  As this type of storage container with a check valve, there is one described in JP-A-11-29178.

  FIG. 4 is a longitudinal sectional view of a storage container with a check valve described in the publication.

  A storage container 500 with a check valve shown in FIG. 4 includes a container body 510 that is open at the top, a lid member 520 that can be fitted to the opening surface of the container body 510, and a reverse attached to the lid member 520. And a stop valve 530.

  Both the container body 510 and the lid member 520 are made of synthetic resin.

  A packing case 521 that opens downward is formed at the periphery of the lid member 520, and a packing 522 made of an elastic body is accommodated in the packing case 521. When the lid member 520 is fitted to the container main body 510, the gap between the lid member 520 and the container main body 510 is closed by the packing 522, and the inside of the container main body 510 is sealed.

  The check valve 530 is formed of an umbrella-shaped portion 531 having an umbrella shape and a central shaft 532 extending downward from the center of the umbrella-shaped portion 531.

  An opening 523 is formed in the lid member 520, and the check valve 530 is attached to the lid member 520 by fitting the central shaft 532 into the opening 523. A ring retaining member 540 is attached to the central shaft 532 near its lower end, and the central shaft 532 is prevented from coming out of the opening 523 by the circular retaining member 540.

  A plurality of vent holes 524 are formed around the opening 523 in the lid member 520. The umbrella-shaped portion 531 of the check valve 530 has a size capable of covering the vent hole 524, and the tip of the umbrella-shaped portion 531 is in contact with the surface of the lid member 520, so that the periphery of the umbrella-shaped portion 531 is Air is prevented from leaking outside.

  The check valve 530 is made of rubber or another elastic body, for example. The check valve 530 has a function of allowing air to pass only from the inside to the outside of the container body 510 and preventing air from entering the inside of the container body 510 from the outside.

  The storage container 500 is used as follows, for example.

  First, after putting food into the container body 510, the lid member 520 is closed with respect to the container body 510. Thereby, the inside of the container main body 510 is hermetically sealed.

  Next, the ingredients inside the storage container 500 are heated by a microwave oven or other heating equipment.

  By heating, the air inside the container main body 510 expands, and the expanded air is discharged to the outside of the storage container 500 via the check valve 530.

  Further, the lid member 520 is pressed downward to forcibly reduce the internal volume of the container main body 510, so that the air remaining in the container main body 510 is outside the storage container 500 via the check valve 530. Is released.

  As a result, the inside of the container main body 510 is deaerated, and as a result, the air concentration and thus the residual air concentration is kept low.

  Thereafter, the storage container 500 is cooled by a refrigerator or other cooling device.

  Since the inside of the container main body 510 is degassed, the residual oxygen concentration is low, and the food in the container main body 510 can be prevented from being oxidized. Can also be prevented from breeding.

  When releasing the sealed state inside the container body 510, the convex portion 533 formed on the umbrella-shaped portion 531 of the check valve 530 is pinched and lifted to open the umbrella-shaped portion 531 and the vent hole 524 is opened. Then, the outside air is caused to flow into the container body 510.

  Alternatively, by pressing the center of the umbrella-shaped portion 531 from above and bending the umbrella-shaped portion 531, the outer periphery of the umbrella-shaped portion 531 is opened, and the outside air is caused to flow into the container body 510 through the vent hole 524. .

  In the conventional storage container 500 shown in FIG. 4, since the check valve 530 is exposed to the outside, for example, the user inadvertently touches the umbrella-shaped portion 531 of the check valve 530 with a finger, and the umbrella The shape portion 531 may be opened. In such a case, outside air flows into the inside of the container body 510 from the location where the umbrella-shaped part 531 is opened, and the degree of vacuum inside the container body 510 is lowered.

  Alternatively, the same situation occurs when another object is placed on the lid member 520 without noticing the check valve 530.

  In addition, an opening 523 is formed in the lid member 520 in order to attach the check valve 530 to the lid member 520, and there are a plurality of openings around the opening 523 in order to evacuate the air inside the container body 510. The vent hole 524 is formed.

  For this reason, when the storage container 500 is used for many years, the lid member 520 is distorted or cracked, particularly in the vicinity of the opening 523 and the vent hole 524. When the lid member 520 is distorted, it becomes difficult to maintain a sealed state between the lid member 520 and the container main body 510, and when cracks occur in the lid member 520, outside air flows from the cracks into the container main body 510. There is a risk of gradually entering.

  The present invention has been made in view of such problems in the conventional storage container, and can prevent inadvertent contact with the check valve. Further, the lid member can be distorted or cracked. An object is to provide a storage container that can be prevented.

  In the following, means for solving the above-described problems will be described using reference numerals used in “Best Mode for Carrying Out the Invention”. These reference numerals are added only for the purpose of clarifying the correspondence between the description of “the scope of claims for utility model registration” and the description of “the best mode for carrying out the invention”.
