  However, the above-described conventional exhalation collection container has room for improvement in terms of simplifying the configuration and preventing the outflow of the exhaled breath easily and reliably.

  Therefore, the present invention has been made in view of the above-described circumstances, and its purpose is to easily and reliably prevent the exhalation of exhaled air that has been blown into the accommodation chamber after simplifying the configuration. It is to provide an exhalation collection container capable of performing the above.

In order to solve the above problems, the present invention proposes the following means.
An exhalation collecting container according to the present invention includes an accommodation recess, a tray body having a flange portion extending outward from an opening edge of the accommodation recess, and affixed to the flange portion to close the accommodation recess. A film material that forms a storage chamber with the storage recess, and the flange portion is formed with a passage that communicates the inside and the outside of the storage chamber through the film material, A bendable portion is formed so as to divide the passage into an interior and an exterior of the housing chamber, and the housing recess includes a bottom wall portion and a peripheral wall portion erected from an outer peripheral edge of the bottom wall portion. The bottom wall portion is configured to be able to be inverted and deformed between the inside and the outside of the peripheral wall portion, starting from a connection portion with the peripheral wall portion .

With such a feature, the inside and the outside of the storage chamber can be separated by bending the passage from the bent portion, so that a separate sealing means such as a cap is not used. Therefore, it is possible to easily and reliably prevent the exhaled breath that has been blown out while simplifying the configuration.
Further, when exhaled air is collected in the storage chamber through the passage, the pressure in the storage chamber increases and the bottom wall portion is pressed outward. Then, the bottom wall portion is reversely deformed from the inner side to the outer side of the peripheral wall portion, starting from the connection portion with the peripheral wall portion. Thereby, the volume in the storage chamber can be increased, and more exhalation can be collected in the storage chamber. Then, by configuring the bottom wall portion so that it can be inverted and deformed, it is possible to quickly determine before and after use at a glance.
In addition, when the exhalation collection container is not used, the bottom wall portion is located inside the peripheral wall portion, so that it is possible to reduce the thickness in the depth direction as compared to when using it. Therefore, it can be stored compactly.

  In the breath collection container of the present invention, the flange portion has an engaging portion that holds the folded portion by bending the bent portion.

  In this case, the sealed state inside the storage chamber can be reliably maintained by holding the passage in a state where it is divided by the engaging portion.

  According to the exhalation collecting container of the present invention, it is possible to easily and reliably prevent the exhalation of the exhaled air blown into the accommodation chamber after simplifying the configuration.

It is a top view of the exhalation collection container in the embodiment of the present invention. It is a side view of an exhalation collection container. It is sectional drawing which follows the AA line of FIG. It is a side view equivalent to FIG. 2, Comprising: It is a figure for demonstrating the effect | action of an exhalation collection container. It is a top view which shows the other structure of an exhalation collection container.

Hereinafter, bottles according to embodiments of the present invention will be described with reference to the drawings.
As shown in FIGS. 1 to 3, the breath collection container 1 according to the present embodiment has a rectangular shape in plan view, and includes a tray body 12 having a housing recess 11 that can store the exhaled breath, and a housing recess. The film material 14 which closes 11 and forms the accommodation chamber 13 between the accommodation recessed part 11 is stuck and comprised in the thickness direction. Hereinafter, the tray body 12 side along the thickness direction of the tray body 12 and the film material 14 is referred to as the lower side, and the film material 14 side is referred to as the upper side. In the plan view of the breath collection container 1, the long side direction is the longitudinal direction and the longitudinal direction. The short side direction orthogonal to is called the short direction.

  The tray body 12 is formed by sheet molding, injection molding, or the like, and has a uniform thickness over substantially the entire region in the longitudinal direction and the short direction. The tray body 12 includes the above-described accommodation recess 11 having the bottom wall portion 21 and the square cylindrical peripheral wall portion 22 erected so as to surround the entire bottom wall portion 21, and the opening edge of the accommodation recess 11. And a flange portion 23 extending outward from the (upper edge).

  The bottom wall portion 21 extends upward as the long side portion extends from the lower end edge of the peripheral wall portion 22 toward the inner side in the short direction, and the short side portion extends from the lower end edge of the peripheral wall portion 22 toward the inner side in the longitudinal direction. Accordingly, it is formed in a trapezoidal shape in a longitudinal section extending upward. Specifically, the bottom wall portion 21 is connected to the inclined portion 25 inclined upward and the inner peripheral edge of the inclined portion 25 from the lower end edge of the peripheral wall portion 22 toward the inside in the longitudinal direction and the short side direction. And a flat portion 24.

The flat portion 24 is formed in a flat surface in cross-sectional shape along the longitudinal direction and the short direction, and faces the film material 14 inside the peripheral wall portion 22.
The inclined portion 25 connects the outer peripheral edge of the flat portion 24 and the lower end edge of the peripheral wall portion 22. The inclined portion 25 is rotatable about a connecting portion between the inclined portion 25 and the peripheral wall portion 22 so as to move the flat portion 24 downward. In addition, you may form the said connection part in a thin part. That is, the inclined portion 25 has an unused position (solid line in FIG. 3) where the flat portion 24 is located above the lower end edge of the peripheral wall portion 22 and a use position (see FIG. 3) below the lower end edge of the peripheral wall portion 22. 3), the bottom wall portion 21 is reversely deformed.

  The film material 14 is a member that is adhered to the upper surface of the flange portion 23 and closes the housing recess 11, and has an outer shape in plan view that is the same shape and size as the tray body 12. And the space enclosed by the film material 14 and the accommodation recessed part 11 comprises the accommodation chamber 13 mentioned above.

  The flange portion 23 described above is formed in a rectangular frame shape in plan view, and one end side in the longitudinal direction with respect to the housing recess 11 is formed longer than the other end side. A concave portion 31 that is recessed downward is formed on one end side in the longitudinal direction of the flange portion 23. The recess 31 has a flat shape in which the length in the short direction is longer than the length in the thickness direction in a longitudinal sectional view along the short direction. Further, in the longitudinal direction, one end side of the recess 31 extends to an end edge on one end side in the longitudinal direction of the flange portion 23, and the other end side communicates with the housing recess 11.

And between the recessed part 31 in the tray body 12, and the film material 14 comprises the channel | path 32 which connects the inside and the exterior of the storage chamber 13 mentioned above through both. In this case, the opening on one end side in the longitudinal direction of the passage 32 constitutes a blowing port portion 32 a for blowing exhalation into the accommodation chamber 13, and the opening on the other end side in the longitudinal direction circulates in the passage 32. An introduction port portion 32 b for introducing exhaled breath into the accommodation chamber 13 is configured. In addition, by pressing one end side in the longitudinal direction of the flange portion 23 (and the film material 14) inward from both sides in the short direction, the concave portion 31 and the film material 14 have their respective short direction center portions. It is bent and deformed in directions away from each other.
In addition, without providing the concave portion 31, the non-bonded portion between the flange portion 23 and the film material 14 extends at one end side to the edge of one end side in the longitudinal direction of the flange portion 23, and the other end communicates with the housing concave portion 11. The passage 32 may be formed when breathing is blown or when the flange portion 23 is pressed inward from both sides in the short direction as described above. . In this case, since the film material 14 is in close contact with the flange portion 23 and closes the passage 32 when not in use, the sealing performance can be further improved.

  Further, the passage 32 is divided into the inside and the outside of the storage chamber 13 at one end side in the longitudinal direction of the flange portion 23 (and the film material 14), specifically at a position corresponding to the central portion in the longitudinal direction of the passage 32. A foldable bending portion 34 is formed as described above. The bent portion 34 has a constricted portion 33 formed so that the width in the short-side direction is reduced from both sides at a position corresponding to the central portion in the longitudinal direction of the passage 32 in the flange portion 23 (and the film material 14). It has a broken line portion (not shown) that is formed in the constricted portion 33 and allows the flange portion 23 to be bent.

  And the flange part 23 (and film material 14) is comprised so that it can bend | fold along a transversal direction from the constriction part 33 (folding line part). In this case, the above-described passage 32 is sealed by bending the flange portion 23 so that one end side in the longitudinal direction of the constricted portion 33 in the flange portion 23 overlaps the other end side in the longitudinal direction in the thickness direction. (Folded state).

Further, a pair of engaging convex portions (engaging portions) 41 are formed on one end side in the longitudinal direction with respect to the constricted portion 33 in the flange portion 23 (and the film material 14). These engagement convex portions 41 are arranged on both sides in the short direction with the passage 32 interposed therebetween, and protrude upward.
On the other hand, a pair of engaging recesses (engaging portions) 42 that can be engaged with the pair of engaging protrusions 41 described above are formed on the other end side in the longitudinal direction with respect to the constricted portion 33 in the flange portion 23. Yes. These engaging recesses 42 are disposed on both sides in the short direction with the passage 32 interposed therebetween, and protrude downward. Each engagement recess 42 is disposed on the opposite side of the engagement convex portion 41 with the constricted portion 33 interposed therebetween, and the inner surface shape thereof is formed to be equal to the outer surface shape of the engagement convex portion 41. Therefore, when the flange portion 23 is bent, the engagement convex portion 41 is fitted and engaged in the engagement concave portion 42, whereby the bent state of the flange portion 23 is maintained.

Next, the usage method of the breath collection container 1 mentioned above is demonstrated.
As shown in FIGS. 1 to 3, first, the subject presses one end side in the longitudinal direction of the flange portion 23 (and the film material 14) inward from both sides in the short direction. Then, the concave portion 31 and the film material 14 are bent and deformed in directions away from each other starting from the central portion in the short direction. As a result, the length of the passage 32 in the thickness direction is enlarged, so that exhalation can be easily blown.

  In this state, when exhaled air is blown from the blowing port portion 32a into the accommodation chamber 13, the blown breath flows through the passage 32 and flows into the accommodating chamber 13 from the introduction port portion 32b. And when the pressure in the storage chamber 13 increases due to the exhaled air flowing into the storage chamber 13, the bottom wall portion 21 is pressed downward. Then, the inclined portion 25 in the bottom wall portion 21 rotates downward from the connection portion with the peripheral wall portion 22, so that the bottom wall portion 21 is inverted and deformed (two points in FIGS. 2 and 3). Chain line). In other words, as the pressure in the storage chamber 13 increases, the flat portion 24 of the bottom wall portion 21 moves to a use position located below the lower end edge of the peripheral wall portion 22. Thereby, the volume in the storage chamber 13 can be increased, and more exhalation can be collected in the storage chamber 13.

  As shown in FIG. 4, after exhalation, the one end side in the longitudinal direction of the constricted portion 33 in the flange portion 23 is folded back from the bent portion 34 (see the arrow in FIG. 4). Then, the passage 32 is deformed so as to be crushed along the thickness direction, so that the film material 14 and the lower surface of the recess 31 come into contact with each other and are divided into the inside and the outside of the housing chamber 13. At this time, one end side in the longitudinal direction of the constricted portion 33 in the flange portion 23 is bent so as to overlap the other end side in the longitudinal direction in the thickness direction, and the engaging convex portion 41 is fitted into the engaging concave portion 42. Thus, the bent state of the flange portion 23 can be maintained.

Therefore, according to the present embodiment, the passage 32 can be sealed only by folding back one end side in the longitudinal direction with respect to the constricted portion 33 in the flange portion 23, starting from the constricted portion 33 (folded portion 34). A separate sealing means such as a cap is not used. Therefore, it is possible to easily and reliably prevent the exhaled breath blown into the storage chamber 13 after simplifying the configuration.
In addition, by engaging the engaging convex portion 41 with the engaging concave portion 42, the bent state of the flange portion 23 can be maintained, so that the sealed state of the inside of the storage chamber 13 can be reliably maintained. Furthermore, since the engaging convex portion 41 and the engaging concave portion 42 are formed integrally with the flange portion 23, the complication of the configuration can be suppressed.

  Furthermore, in this embodiment, since the bottom wall part 21 is configured so as to be able to be inverted and deformed as the pressure in the storage chamber 13 increases, it is possible to quickly determine at a glance whether or not the breath collection container 1 is used. Furthermore, when the exhalation collection container 1 is not used, the bottom wall portion 21 is located inside the peripheral wall portion 22, so that the thickness can be reduced as compared with the use. Therefore, it can be stored compactly.

  As mentioned above, although embodiment of this invention was explained in full detail with reference to drawings, the concrete structure is not restricted to this embodiment, The design change etc. of the range which does not deviate from the summary of this invention are included.

In the above-described embodiment, the case where the flange portion 23 is folded once with the constricted portion 33 as a starting point has been described. For example, as shown in FIG. 5, one end in the longitudinal direction from the one end side in the longitudinal direction of the flange portion 23 (and the film material 14) on which the engagement convex portion 41 is formed in the above-described embodiment via the bent portion 51. You may extend the blowing part 52 to the side. The blowing portion 52 is formed to have a shorter length in the short direction than the other end side in the longitudinal direction with respect to the folded portion 51, and the user can easily hold the blowing portion 52. Further, the length in the longitudinal direction of the blowing portion 52 and the bent portion 51 is equal to the length between the bent portions 34 and 51, and the passage 32 can be folded so as to be wound through the two bent portions 34 and 51. It can be done. Therefore, more reliable sealing is possible.
Further, the constricted portion 33 may not be provided.

In the above-described embodiment, the case where the flat portion 24 is formed on the flat surface and the inclined portion 25 is formed on the inclined surface has been described. However, the present invention is not limited thereto, and the flat portion 24 and the inclined portion 25 are formed on the curved surface. May be.
Further, the housing recess 11 is not limited to one, and a plurality of housing recesses 11 may be provided.
