Description

  The present invention relates to a decompression packaging container, and more particularly to a container used for decompression packaging (sometimes called a vacuum pack or the like) that accommodates an object to be contained in a decompressed state.

A decompression packaging container (sometimes referred to as a vacuum pack container or the like) that accommodates an object to be stored in a depressurized state is such that oxygen in the air, surrounding germs, dust, etc. come into contact with the object to be stored. In order to prevent or reduce the deterioration (for example, oxidation, decay, contamination, etc.), the food field (for example, containing food as an object to be contained) has been used mainly (for example, patent documents). 1).
Patent Document 1 stated that “the object of the present invention is to provide a processed shrimp processed food characterized in that the shrimp peel is wrapped with a leaf of a plant having antibacterial properties as a water-holding packaging material and vacuum-packed with a film” ( Specifically, “Paper shrimp peels are wrapped in antibacterial plant leaves as a water-retaining packaging material and vacuum-packed with a film. A processed shrimp processed food characterized in that (Claim 1 of Patent Document 1) is disclosed, whereby “the processed shrimp processed food of this device is used in the leaf of a plant that is compatible with the peeled shrimp. In addition to improving the shelf life due to its antibacterial properties and vacuum packaging, it is also softened by water retention. In addition, a high-quality noble scent is brewed and you can enjoy the scent along with the taste, so even a small bite has a comfortable texture and you have the satisfaction of eating It has an excellent effect that it will remain as an unforgettable lingering effect ”(paragraph number 0011 of Patent Document 1).
That is, Patent Document 1 discloses a decompression packaging container (vacuum packed with a film) that accommodates a white shrimp peel as an object to be contained in a decompressed state.

Registered utility model No. 3127387 (paragraph numbers 0004 to 0011, FIG. 1 to FIG. 3, abstract, etc.)

The vacuum packaging container described in Patent Document 1 (vacuum pack with a film containing the shrimp peel in a decompressed state as an object to be contained) vacuum-packs the shrimp peel wrapped with the leaf of the plant with the film, so in the air Prevent or reduce deterioration (for example, oxidation, decay, contamination, etc.) of contained matter (shrimp peel) due to contact of oxygen, surrounding germs, garbage, etc. with contained matter (shrimp peel) However, under atmospheric pressure, atmospheric pressure is applied to the vacuum-packed film, and this force causes a problem that the object to be contained (shrimp peel) is deformed or crushed in the vacuum pack.
Such deformation or the like of the object to be stored may reduce the commercial value of the object to be stored, or it may become impossible to use the object to be stored.

  Therefore, in the present invention, like the decompression packaging container described in Patent Document 1, the decompression packaging container (vacuum) that does not cause problems such as deformation of the contents in the decompression packaging container (vacuum pack) due to the application of atmospheric pressure. Pack).

The decompression packaging container of the present invention (hereinafter referred to as “the present container”) is a decompression packaging container that accommodates an object to be stored in a decompressed state, and defines an accommodation space in which the object can be accommodated and an accommodation space. A sealable bag body capable of accommodating a protective aggregate having a communication port for communicating the inner surface and the outer surface, and a protective aggregate containing an object to be stored in the storage space in a reduced pressure state. And a vacuum packaging container in which the housing space is not crushed even if the internal space of the bag body is in a reduced pressure state.
The container roughly includes a protective aggregate and a bag.
The bag body can be sealed (usually liquid-tight and air-tight) that has been conventionally used for vacuum packaging (vacuum packing) (usually a liquid-tight and air-tight synthetic resin or rubber sheet. Or formed by a film or the like), and the protective aggregate containing the object to be stored is decompressed in the inner space of the bag body (which is lower than the pressure around the container, for example, the container In the case of being placed under atmospheric pressure, the pressure is lower than atmospheric pressure).
The protective aggregate stores an object to be stored in a storage space of the protective aggregate. The protective aggregate has a communication port that communicates the inner surface of the protective aggregate that defines the accommodation space (the surface that faces the accommodation space) and the outer surface of the protective aggregate.
For this reason, when the protective aggregate containing the object to be stored in the storage space is stored in the internal space of the bag body in a reduced pressure state, the atmosphere (for example, air) existing in the storage space for storing the object to be stored is removed through the communication port, As the accommodation space for accommodating the objects to be stored is depressurized, the objects to be stored are vacuum-packed (vacuum packed) as in the prior art. Thus, when the protective aggregate containing the object to be accommodated in the accommodation space is accommodated in the internal space of the bag body in a reduced pressure state, in this container, even if the internal space of the bag body is in a reduced pressure state, the object to be accommodated The accommodation space that accommodates the container is not crushed (the deformation of the accommodation space that occurs when the internal space of the bag body is in a reduced pressure state does not deform or crush the object to be contained). Even if the container is applied to the container, the force due to the atmospheric pressure is not directly applied to the object to be stored, and the problem does not occur that the object to be stored is deformed or crushed in the container. It is accommodated with a certain amount of play in it (the object to be accommodated is movably accommodated within a certain range within the accommodation space).

The protective aggregate may have a closed curve portion (hereinafter referred to as a “closed curve portion holding container”) that surrounds the accommodation space with a closed line on a cut surface of any one plane passing through the accommodation space. .
In this way, if the protective aggregate has a closed curve portion, the closed curve portion is a continuous line (both ends coincide with each other) at the cut surface (cut surface by any one plane passing through the storage space). The storage space for storing the object to be stored at the position of the cut surface is surrounded by the protective aggregate (closed curve portion), and the force due to atmospheric pressure is near the position. Can be reliably prevented or reduced from being directly applied to the contained object, and the problem that the contained object is crushed in the container is effectively prevented or reduced.

In the case of a closed curve portion holding container, the protective aggregate may have at least two different closed curve portions.
By doing so, there are two or more different positions where the accommodation space for accommodating the objects to be surrounded is at least two positions surrounded by the protective aggregate (closed curve portion), so that the force due to atmospheric pressure is more directly and directly applied to the objects to be stored. It can be prevented or reduced, and the problem that the contents are crushed in the container is extensively and effectively prevented or reduced.

In the case of the closed curve portion holding container, the closed curve portion may be one that surrounds the inner surface of the bag body so as to be in close contact with the outer surface of the protective aggregate (hereinafter referred to as “closed curve partial bag body close container”).
When the protective aggregate containing the objects to be accommodated in the accommodating space is accommodated in the bag body internal space in a reduced pressure state, the bag body is inward (according to the degree of pressure reduction of the bag inner space by the atmospheric pressure applied to the outer surface of the bag body ( Pressed in the direction of the housing space. Since the force applied to the bag body is supported by the inner surface of the bag body being in close contact with the outer surface of the protective aggregate, etc., the inner surface of the bag body at the closed curved portion surrounding the accommodation space with a closed line on the cut surface Is surrounded by the outer surface of the protective aggregate so that the closed curved portion can support the force pushing the outer surface of the protective aggregate inward in a well-balanced manner (that is, the outer surface of the protective aggregate is inward). Since the pushing force is applied from the periphery to the inside so as to surround the receiving space, this can be well supported by the closed curved portion surrounding the receiving space by a closed line.

In the case of the closed curve part bag body intimate container, the outer surface of the protective aggregate to which the inner surface of the bag body is in close contact may be formed by an outwardly convex curve in the closed curve part.
If the inner surface of the bag body presses the outer surface of the protective aggregate inward, the outer surface of the protective aggregate that the inner surface of the bag body is in close contact with is formed in a tangential direction with respect to the convex curve. Since it acts as a force to compress the closed curve part (normal materials are more resistant to compressive force than bending force and tensile force), this container (protective aggregate) can be constructed firmly (same strength) In order to make it easier, the wall thickness can be smaller, and it can be made lighter and cheaper.)
The “outwardly convex curve” refers to a curve in which all points on a line segment connecting any two points existing in an inner region surrounded by a closed curve belong to the region. For example, A circle or an ellipse can be exemplified.

In the case of a closed curve portion holding container, the protective aggregate may have a hollow tubular shape (hereinafter referred to as “hollow tubular container”) along a reference straight line that is a straight line intersecting the cut surface.
In this way, the protective aggregate has a hollow tubular shape along a reference straight line that intersects with the cut surface (any one plane passing through the accommodation space) that the closed curve portion surrounds the accommodation space with a closed line. By doing so, the protective aggregate having a hollow tubular shape along the reference straight line is inserted into the interior space of the bag body (usually, it can be easily inserted if inserted in the direction along the reference straight line), and the bag body. If the inner space is housed in a reduced pressure state, the hollow interior of the protective aggregate having a hollow tubular shape can function well as the housing space.

In the case of a hollow tubular container, the protective aggregate is a cylindrical aggregate having a hollow substantially cylindrical shape along a reference straight line, and a substantially spherical crown shape attached to one end of both ends of the cylindrical aggregate along the reference straight line. One end spherical crown aggregate having an outer surface, the other end spherical crown aggregate having a substantially spherical crown-shaped outer surface attached to the other end of the both ends, a cylindrical aggregate, one end spherical crown aggregate, and the other end spherical crown And the communication port formed in at least one of the aggregates.
Thus, a cylindrical aggregate having a hollow substantially cylindrical shape along the reference straight line, a one-end spherical crown aggregate having a substantially spherical crown-shaped outer surface attached to one end side of both ends of the cylindrical aggregate, and By configuring the other end spherical crown aggregate having a substantially spherical crown-shaped outer surface attached to the other end side so that the protective aggregate has (the protective aggregate forms a so-called capsule shape as a whole). The housing space can be increased by making the hollow interior of the hollow cylindrical aggregate having a substantially cylindrical shape along the reference straight line function well as the housing space (for example, a spherical material having the same radius as the cylindrical aggregate) In addition, it is obvious that the outer surface of the protective aggregate, which is closely in contact with the inner surface of the bag body, is formed by an outwardly convex curve, so that the container (protective aggregate) can be constructed robustly (the same Smaller to configure strength Wall thickness well, can be reduced in weight and low cost.). Further, the communication port is formed in at least one of the cylindrical aggregate, the one-end spherical crown aggregate, and the other-end spherical crown aggregate, whereby the inner surface and the outer surface that define the accommodation space can be communicated with each other.

In this container, the accommodation space may not be in contact with the inner surface of the bag body.
Since the storage space for storing the objects to be stored does not face the inner surface of the bag body, the objects to be stored and the inner surface of the bag body do not come into contact with each other. Can be prevented or reduced. The defect may be a defect that may occur in one or both of the object to be stored and the inner surface of the bag body. For example, the inner surface of the container to be inadvertently punctured or incised by contacting the inner surface of the bag body. (For example, shrimp, fish antennae, spines, hard fins, etc., which are contained, may cause the inner surface of the bag to puncture or incise unexpectedly) Can be mentioned.

In the present container, the object to be accommodated in the accommodation space may be one that is visible from the outside of the protective aggregate (hereinafter referred to as “container visually-visible container”).
By carrying out like this, the state of the to-be-contained object accommodated in accommodation space can be grasped | ascertained correctly by visual observation from the exterior of a protective aggregate.

  In the case of a container capable of visually checking the object to be stored, various methods may be used to make the object stored in the storage space visible from the outside of the protective aggregate, for example, a part of the protective aggregate. Alternatively, the entire object may be made of a transparent material, or the object to be accommodated may be visible from the outside of the protective aggregate via a communication port that connects the inner surface and the outer surface that define the accommodation space. In particular, if the object to be accommodated in the accommodating space is visible from the outside of the protective aggregate via the communication port, the object to be accommodated in the accommodating space can be visually confirmed from the outside of the protective aggregate. Therefore, it is not necessary to take a special method for making the container (protective aggregate), the structure of the container (protective aggregate) can be simplified, and the container (protective aggregate) can be manufactured inexpensively and easily.

  As described above, this container is provided with a protective aggregate and a bag body. Among these, the bag body is a general-purpose sealable product that has been conventionally used for vacuum packaging. Therefore, it is not always necessary to manufacture and / or sell the protective aggregate and the bag as a set, and only the protective aggregate may be manufactured and / or sold (the person who obtained the protective aggregate). Can constitute this container using a general-purpose bag.)

  Embodiments of the present invention will be described in detail with reference to the drawings, but the present invention is not limited thereto.

FIG. 1 is a front view showing a protective aggregate 51 for constituting an example of the decompression packaging container (this container) of the present invention, FIG. 2 is a cross-sectional view taken along the line AA of FIG. 1, and FIG. 1 is a cross-sectional view taken along line BB of FIG. 1, and FIG. 4 is a cross-sectional view taken along line CC of FIG. An example of the protective aggregate 51 will be described with reference to FIGS. 1 to 4.
The protective aggregate 51 is roughly a cylindrical aggregate 61 having a hollow, substantially cylindrical shape along a virtual reference straight line D (included in the AA cross section described above), and both ends of the cylindrical aggregate 61. One end spherical crown aggregate 71 having a substantially spherical crown-shaped outer surface 73 attached to one end 61a side of 61a, 61b, and a substantially spherical crown-shaped outer surface 83 attached to the other end 61b side of both ends 61a, 61b. The other end spherical crown aggregate 81. The cylindrical aggregate 61 and the one-end spherical crown aggregate 71 are attached to each other by being bonded to each other, and the cylindrical aggregate 61 and the other-end spherical crown aggregate 81 are hinged so that they can be rotated with each other within a predetermined range. It is rotatably attached by a member 91 (a member that rotatably connects both sides within a predetermined range) (for ease of illustration and understanding, the cylindrical aggregate 61 and the one-end crown crown 71 are attached. And the space between the cylindrical aggregate 61 and the other end spherical crown aggregate 81 is also illustrated wider than actual.
The protective aggregate 51 is formed of a colorless and transparent resin material (for example, hard polyethylene) except for the hinge member 91 formed of a colored and opaque resin material.

The cylindrical aggregate 61 includes a plurality of (here, specifically, 12) ring members 63 and rod-like connection members 65a, 65b, 65c, and 65d that connect the plurality of ring members 63 to each other.
The plurality of ring members 63 are all formed in the same shape and the same dimensions, and are arranged at equal intervals with each other (adhered) by connecting members 65a, 65b, 65c, and 65d. All of the ring members 63 have an inner surface 63a substantially in contact with a side surface of a right circular cylinder having a radius r1 with the reference straight line D as an axis, and a side surface of a right circular cylinder with a radius r2 (where r1 <r2) having the reference straight line D as an axis. The outer surface 63b is disposed so as to be substantially in contact with each other, and the thickness t along the reference straight line D is substantially the same. Also, all of the ring members 63 are disposed so as to belong to a plane perpendicular to the reference straight line D, and each of the ring members 63 substantially forms a rotating body having the reference straight line D as an axis.
The connecting members 65a, 65b, 65c and 65d are all arranged so as to extend substantially parallel to the reference straight line D (that is, the connecting member 65a extends along a straight line substantially parallel to the reference straight line D). The connecting member 65b extends along a straight line that is substantially parallel to the reference straight line D, and the connecting member 65c extends along a straight line that is substantially parallel to the reference straight line D. The connecting member 65d is disposed so as to extend along a straight line substantially parallel to the reference straight line D.) As described above, the plurality of ring members 63 are substantially equal. They are connected so that there is an interval.
As described above, the cylindrical aggregate 61 has a hollow inner portion 67 (a part of the accommodation space 13) having a right circular column shape with a radius r1 with the reference straight line D as an axis, and an outer portion 69 and an inner portion of the cylindrical aggregate 61. And a communication port 68 (a gap formed between a plurality of ring members 63 arranged at equal intervals).

Both the one-end spherical crown aggregate 71 and the other-end spherical crown aggregate 81 are formed in the same shape and the same size, and have an outer diameter r2 having a spherical hollow interior with a radius r1 (where r1 and r2 are those described above) 1) is formed by one end of the two parts when the sphere is cut by a plane including its center, and the other part of the two parts is the other end of the crown crown 81. is there. For this reason, the one-end spherical crown 71 has a hemispherical hollow interior 75 with a radius r1 and a hemispherical outer surface 73 with a radius r2. Similarly, the other-end spherical crown 81 has a hemispherical hollow interior 85 with a radius r1 and a hemispherical outer surface 83 with a radius r2.
The one-end crown crown 71 is attached by attaching a cut surface to a ring member 63 located at one end 61a of the cylindrical aggregate 61 so that the reference straight line D substantially passes through the center position of the sphere having the outer diameter r2. (Adhesive is not shown).
The other end spherical crown aggregate 81 is rotated through a hinge member 91 to a ring member 63 positioned at the other end 61b of the cylindrical aggregate 61 so that the reference straight line D substantially passes through the center position of the sphere having the outer diameter r2. The other end of the cylindrical aggregate 61 is attached to be movable (the rotation direction of the other-end spherical crown aggregate 81 with respect to the cylindrical aggregate 61 is indicated by an arrow E in FIG. 1). The cut surface of the sphere can be brought into contact with the ring member 63 positioned at 61b. FIGS. 1 and 2 show a state in which the cut surface of the sphere is substantially in contact with the ring member 63.

Next, a method of using an example of the decompression packaging container (this container) of the present invention using the protective aggregate 51 will be described.
FIG. 5 is a diagram illustrating a first step of the method of using the container using the protective aggregate 51. With reference to FIG. 5, the 1st step of the usage method of this container is demonstrated. First, from the state shown in FIG. 1, the other end spherical crown aggregate 81 is rotated around the hinge member 91 with respect to the cylindrical aggregate 61 (in FIG. 1, it is rotated clockwise), and shown in FIG. 5. Like that. In the state of FIG. 5, the ring member 63 at the other end 61b is exposed, so the ring member 63 on the other end 61b side (as described above, has a circular opening with the radius r1. In particular, FIGS. From the above, it is possible to insert a contained object into the hollow interior 67 of the cylindrical aggregate 61. Here, the frozen shrimp 101 is inserted into the hollow interior 67 of the cylindrical aggregate 61 from the ring member 63 on the other end 61b side as an object to be contained (the insertion direction is indicated by an arrow F in FIG. 5). After inserting the frozen shrimp 101 into the hollow interior 67 of the cylindrical aggregate 61, the other end spherical crown aggregate 81 is rotated around the hinge member 91 with respect to the cylindrical aggregate 61 from the state shown in FIG. 1 is rotated counterclockwise (arrow G in FIG. 5), and the other end 61b of the cylindrical aggregate 61 is covered with the other end spherical crown 81 (as shown in FIGS. 1 and 2). By setting the end spherical crown aggregate 81 to the rotational position, the circular opening having the radius r1 of the ring member 63 on the other end 61b side is closed by the other end spherical crown aggregate 81.
In this way, the hollow interior 67 of the cylindrical aggregate 61, the hollow interior 75 of the one-end spherical crown aggregate 71, and the hollow interior 85 of the other-end spherical crown aggregate 81 communicate with each other and are frozen. The first step in which the shrimp 101 is accommodated is completed.

FIG. 6 is a diagram illustrating a second step of the method of using the present container using the protective aggregate 51. With reference to FIG. 6, the 2nd step of the usage method of this container is demonstrated.
As shown in FIG. 6, the protective aggregate 51 in which the frozen shrimp 101 is accommodated in the accommodation space 13 in the first step is placed in the internal space 23 of the bag 21 made of synthetic resin (here, colorless and transparent polyethylene) as a bag body. Inserted. Here, the bag 21 is composed of a first sheet 25 and a second sheet 27 which are colorless and transparent thick polyethylene sheets having the same main surface and the same rectangular shape, and the first sheet 25 and the second sheet 27 are vertically arranged. In a state of being superposed so as to overlap each other, they are joined by a fusion part 21m that is heat-sealed with a predetermined width along three sides. For this reason, the first sheet 25 and the second sheet 27 that are superposed vertically and heat-sealed along the three sides are formed with a communication opening 24 that communicates with the internal space 23 by the remaining one side that is not heat-sealed. ing. The protective aggregate 51 containing the frozen shrimp 101 is inserted into the internal space 23 through the communication opening 24, and the second step is completed as shown in FIG.

Next, in the third step of the method of using the container using the protective aggregate 51, the air in the internal space 23 into which the protective aggregate 51 containing the frozen shrimp 101 is inserted in the second step described above is extracted. Specifically, the bag 21 in which the protective aggregate 51 containing the frozen shrimp 101 is held in the internal space 23 in the second step is placed in a decompression chamber (not shown) and decompressed. As a result, the housing space 13 (the housing space 13 formed by the hollow interior 67 of the cylindrical aggregate 61, the hollow interior 75 of the one-end spherical crown aggregate 71, and the hollow interior 85 of the other-end spherical crown aggregate 81 is integrally formed. The air existing in the internal space 23 including the gas flows out from the communication opening 24 and is deaerated (depressurized).
And in the 4th step of the usage method of this container using the protective aggregate 51, the bag 21 from which the air existing in the internal space 23 including the accommodation space 13 was removed to a desired degree in the above-described third step is sealed. Specifically, the first sheet 25 and the second sheet 27 constituting the bag 21 are heat-sealed (under reduced pressure) along one side that is not heat-sealed (in FIG. The communication opening 24 is sealed off with a predetermined width along the side 27k.
Finally, a reduced-pressure packaging container (main container) for taking out the bag 21 sealed in the fourth step from a decompression chamber (not shown) under atmospheric pressure and storing the frozen shrimp 101 as an object to be contained in a decompressed state. Completed. At this time, the outer surface of the bag 21 is pushed inward by atmospheric pressure, so that the inner surface of the bag 21 pushes the outer surface of the protective aggregate 51 inward, but the protective aggregate 51 has sufficient strength here. The housing space 13 in which the frozen shrimp 101 is housed is hardly deformed and is not crushed.

FIG. 7 is a sectional view of the container 11 (a decompression packaging container that accommodates the frozen shrimp 101 as an object to be contained in a decompressed state) (the sectional position of the protective aggregate 51 is the AA section described above).

The accommodation space 13 is in a decompressed state (pressure is lower than atmospheric pressure), and the outer surface of the bag 21 is pushed toward the inside (in the direction of the protective aggregate 51) by atmospheric pressure, whereby the inner surface of the bag 21 is protected bone. The outer surface of the material 51 is pushed inward (in the direction of the accommodation space 13), but the protective aggregate 51 has sufficient strength so that the accommodation space 13 in which the frozen shrimp 101 is accommodated is hardly deformed and is not crushed. .

As described above, the container 11 is a decompression packaging container that accommodates an object (here, frozen shrimp 101) in a decompressed state, and an accommodation space 13 that can accommodate the object (frozen shrimp 101). A protective aggregate 51 having a communication port 68 that communicates an inner surface (here, the inner surface 63a of the ring member 63) and an outer surface (here, the outer surface 63b of the ring member 63) defining the housing space 13, A sealable bag body (here, bag 21) capable of storing the protective aggregate 51 containing the object to be stored (frozen shrimp 101) in the storage space 13 in a reduced pressure state in the internal space 23, and Even if the internal space 23 of the bag body (bag 21) is in a reduced pressure state, the storage space 13 is not crushed.
In the present container 11, the protective aggregate 51 passes through any one of the planes (in this case, a plane perpendicular to the reference straight line D that cuts each ring member 63 with respect to each ring member 63). It has the closed curve part (individual ring member 63) surrounding the accommodation space 13 by the closed line (here substantially circular) in the cut surface by. Moreover, the cut surface by any one plane (plane perpendicular | vertical with respect to the reference straight line D which cut | disconnects the one end spherical crown aggregate 71 and the other end spherical crown aggregate 81) in which the protective aggregate 51 passes through the accommodation space 13. The closed space portion (one end spherical crown aggregate 71 and the other end spherical crown aggregate 81) surrounding the accommodating space 13 with a closed line (here, substantially circular) in FIG.
The protective aggregate 51 has at least two or more different closed curve portions (in this case, individual ring members 63, one end spherical crown aggregate 71 and the other end spherical crown aggregate 81).
In addition, in the closed curve portion (individual ring member 63, one end spherical crown aggregate 71 and the other end spherical crown aggregate 81), the inner surface of the bag body (bag 21) is surrounded so as to be in close contact with the outer surface of the protective aggregate 51. (See in particular FIG. 7).
Furthermore, in the closed curve portion (individual ring member 63, one end spherical crown aggregate 71 and the other end spherical crown aggregate 81), the outer surface of the protective aggregate to which the inner surface of the bag body (bag 21) is in close contact is an outwardly convex curve. (Both are circular here).

In the container 11, the protective aggregate 51 has a hollow tubular shape (mainly a portion formed by the cylindrical aggregate 61) along a reference straight line D that is a straight line intersecting the cut surface.
The protective aggregate 51 is attached to the one end 61a side of the cylindrical aggregate 61 having a hollow substantially cylindrical shape along the reference straight line D and both ends 61a and 61b of the cylindrical aggregate 61 along the reference straight line D. One end spherical crown aggregate 71 having an outer surface 73 having a substantially spherical crown shape (here, the outer surface of a hemisphere) and a substantially spherical crown shape (here, the outer surface of the hemisphere) attached to the other end 61b side of the both ends 61a, 61b. The other end spherical crown aggregate 81 having an outer surface 83, the cylindrical aggregate 61, the one end spherical crown aggregate 71, and the other end spherical crown aggregate 81 are formed on the cylindrical aggregate 61 (here, the cylindrical aggregate 61). And a communication port 68.

In the container 11, the accommodation space 13 is not in contact with the inner surface of the bag body (bag 21). That is, a hollow interior 67 (a hollow interior having a right circular column shape having a radius r1 with the reference straight line D as an axis) included in the cylindrical aggregate 61 and a hollow interior 75 (a hemisphere having a radius r1) included in the one-end spherical crown aggregate 71 are provided. ) And the hollow interior 85 (hemispherical hollow interior with radius r1) of the other end spherical crown aggregate 81 are connected and integrated to form the accommodating space 13.

Here, the object to be accommodated (the frozen shrimp 101) accommodated in the accommodating space 13 is visible from the outside of the protective aggregate 51 through the communication port 68 (see particularly FIG. 6).

By using this container 11, the protective aggregate is used in comparison with the case of using a reduced pressure packaging container provided with an air vent valve and an airtight opening / closing door for taking in and out an object in a sealed and robust container having an internal space. The bag can be vacuum-packed with a simple structure of a bag body, and the vacuum-packaging can be used easily and inexpensively.
In other words, providing an air vent valve and an airtight opening / closing door in a sealed container requires a complicated manufacturing process and requires expensive parts, which makes the manufacturing cost expensive. Therefore, maintenance inspections are also required because of the occurrence of malfunctions, resulting in increased costs in both production and use.
On the other hand, the main container 11 having a simple structure of a protective aggregate and a bag is inexpensive in both production and use, and the main container 11 can be made disposable in some cases.
As described above, the container 11 enables easy and inexpensive decompression packaging, and can be frequently used in various fields including the food field.
