Description

  The present invention relates to an injection container for injecting an inclusion.

  Conventionally, as a spray-type container that sprays inclusions such as insecticides / insecticides, cosmetics, fire extinguishing agents, so-called aerosol products that spray a liquid pressurized by compressed gas inside the container through a thin tube Are known. Such conventionally known aerosol products usually use a metal can having a pressure-resistant structure, so that it is difficult to visually confirm the enclosed matter. For this reason, it is common to estimate the remaining amount of the inclusion by lifting or shaking the metal can.

  On the other hand, it is also known that an expandable bag body is filled with an enclosure without using a metal can having a pressure-resistant structure, and the bag body is placed in a container (see, for example, Patent Document 1). This container is provided with a window on the side surface, and by checking the size of the bag in the container through the window, the remaining amount of the enclosure can be estimated.

  However, the container disclosed in Patent Document 1 has the following problems. If the bag in the container shrinks and becomes smaller as the amount of inclusions decreases, the bag separates from the inner wall of the container, making it difficult to visually confirm the size of the bag through the window. For this reason, it becomes difficult to estimate the remaining amount of the inclusion. In addition, since the bag is covered with a container, when the amount of inclusions decreases, the inclusion cannot be forcibly discharged from the inside of the bag, and the entire container is discarded while leaving the inclusions. I have to.

  The present invention has been made to solve the above-described problems, and can visually check the remaining amount of the enclosed material, and when the enclosed material is low, it can be forcibly discharged by applying force from the outside. It is an object to provide a simple injection container.

<First embodiment>
FIG. 1 is a perspective view (1A) of a spray container according to a first embodiment of the present invention and a longitudinal sectional perspective view (1B) of the spray container when the spray container is cut in the height direction by a surface S. Each is shown. 2 is a perspective view (2A) of a state in which the injection container of FIG. 1 is filled with an inclusion, and a longitudinal section similar to FIG. A perspective view (2B) is shown respectively.

  The injection container 1 according to this embodiment is filled with the inclusion 30 containing at least gas or liquid at a pressure higher than the external pressure, and opens the valve 6 connected to the actuator 5 to be described later, thereby bringing the filled inclusion 30 to the outside. A container that can be sprayed. The enclosure 30 is not particularly limited as long as it is any one of gas, liquid only, a mixture of gas and liquid, a mixture of gas and solid, a mixture of liquid and solid, a mixture of gas, liquid and solid, a fire extinguishing agent, Insecticides, insecticides, paints, deodorants, lubricants (for example, for rust prevention), human body deodorants, antiperspirants, pharmaceuticals, shaving cream, body soap, cosmetics, edible oils, liquid seasonings Examples thereof include hair materials, hair supplies, perfumes and the like. The injection container 1 includes an expandable bag body 2 that can be filled with the inclusion 30 and is exposed to the outside, and a lid member 3 that is fixed to the opening side of the expandable bag body 2. The stretchable bag body 2 is a transparent or translucent bag body that elastically expands and contracts. The stretchable bag 2 is preferably a bag that can be filled with the inclusion 30 so that the inclusion 30 can be sprayed to the outside at a maximum of 5 megapascals. However, the injection pressure of the inclusion 30 from the elastic bag 2 is not necessarily limited to the above pressure.

  The lid member 3 preferably has a concave portion that is recessed toward the stretchable bag body 2 and has a protruding portion 4 that protrudes upward at a substantially central portion of the concave portion. The protruding portion 4 includes an actuator 5 that can be pushed toward the elastic bag body 2 side above the protruding portion 4. The actuator 5 has a valve 6 at the bottom, and the protruding portion is inserted into the protruding portion 4 so that the valve 6 can open and close an opening formed on the top surface of the protruding portion 4. 4 is arranged at the top. The actuator 5 includes an injection port 7 formed on the upper side surface thereof. The injection port 7 is connected from the path 8 formed inside the actuator 5 to the internal space 20 of the stretchable bag body 2 through the inside of the protrusion 4. The lid member 3 includes an annular fixing member 9 on the back side. The elastic bag body 2 has an opening 21 sandwiched between the inner wall of the lid member 3 and the fixing member 9, so that the internal space 20 does not communicate with the outside as long as the valve 6 is closed. It is fixed. The lid member 3 is preferably made of metal since it is necessary to close the opening 21 so as not to leak the inclusion 30 filled in the elastic bag body 2 to the outside. However, the cover member 3 is not limited in its constituent material, and may be made of a material other than a metal such as resin or ceramics.

  The stretchable bag body 2 is a bag body that is elongated from the opening portion 21 through the central portion 22 to the closing portion 23 that closes in a substantially hemispherical shape. The opening 21 is a funnel-shaped portion having a thickness of an average thickness t1. The central portion 22 is a substantially cylindrical portion that communicates with the end portion 25 of the opening 21 and has a thickness of an average thickness t2 (> t1). The blocking portion 23 is a portion having a substantially U-shaped cross section that communicates with the step portion 26 of the central portion 22 on the side opposite to the end portion 25 and has a thickness of an average thickness t3 (<t2). The reason why the thickness t2 of the central portion 22 is made larger than the thicknesses t1 and t3 of the opening 21 and the closing portion 23 is to suppress the expansion of the central portion 22 in the radial direction, so that the stretchable bag body 2 has a spherical shape as a whole. This is to make it difficult to expand. The central portion 22 of the expandable bag body 2 is preferentially expanded in the length direction, so that the expandable bag body 2 is expanded vertically and, as a result, the spray container 1 can be prevented from rolling. In order to suppress expansion of the central portion in the length direction of the stretchable bag body 2, at least the thickness of the center of the length of the stretchable bag body 2 that can be expanded in the lengthwise direction is set to the thickness on both ends of the center. It should be thicker. In this embodiment, the “center of the inflatable length” is present in the central portion 22. The wall thickness t2 of the central portion 22 is the largest of all the wall thicknesses of the stretchable bag body 2, including the wall thickness t1 of the opening 21 of the stretchable bag body 2 and the wall thickness t3 of the closing portion 23. In addition, when there exists another means which prevents the excessive expansion | swelling of the length direction center part of the expansion-contraction bag body 2, for example, when a means, such as surrounding the said center part with a belt or a ring, is taken, or the expansion-contraction bag body 2 When it is not necessary to suppress the expansion of the central portion, the relationship between the thicknesses t1, t2, and t3 may not be employed. In such a case, for example, the stretchable bag body 2 may be formed so that the wall thicknesses t1, t2, and t3 are substantially equal.

  The elastic bag body 2 is not particularly limited as long as it is a transparent or translucent bag body that can be filled with the inclusion 30 and elastically expands and contracts. For example, silicone rubber, urethane rubber, isoprene rubber Thermosetting elastomers such as ethylene propylene rubber, natural rubber, ethylene propylene diene rubber or styrene butadiene rubber, thermoplastic elastomers such as urethane, ester, styrene, olefin, butadiene or fluorine, or composites thereof It is suitably composed of things and the like. The stretchable bag body 2 is preferably composed of a resin material having high acid resistance or alkali resistance, oil resistance, solvent resistance, etc. so as not to be easily denatured even when it comes into contact with the inclusion 30. It is preferably composed of a fluorine-based rubber. However, a fluorine coating may be applied to the inner surface of the elastic bag body 2, and a material having a lower resistance to modification than fluorine-based rubber, for example, silicone rubber, may be used as the main material of the elastic bag body 2 itself. Moreover, when the chemical action of the enclosure 30 is weak, it is preferable to use a silicone rubber rich in elasticity as the material of the stretchable bag body 2. In this specification, “resin” is broadly interpreted to include rubber. Also, the terms “transparent” and “translucent” do not have any special boundary between them, but simply “translucent” is less transparent than “transparent”. However, both terms are used to eliminate “opacity”. Therefore, when the enclosure 30 or other objects (such as the enclosure 30) are placed in the internal space 20 of the elastic bag body 2, the enclosure 30 or the like can be visually recognized from the outside of the elastic bag body 2 by the human naked eye. As long as the stretchable bag body 2 is a transparent or translucent bag body.

  The injection container 1 includes a pedestal 10 on the closing part 23 side (that is, the bottom part) of the elastic bag body 2. The pedestal 10 is an example of a holding part that is provided on a part of the outer surface of the stretchable bag body 2 and holds the spray container 1 at a place where it is placed. In this embodiment, the pedestal 10 is a member made of a metal or a hard resin material and having a diameter that increases from the stretchable bag body 2 side toward the side where it is placed. However, the pedestal 10 may be a suction cup formed of rubber or the like rich in elasticity. The pedestal 10 includes a concave portion 11 in which the closed portion 23 side (that is, the lower side) is recessed. The recess 11 is provided with a through-hole 12 penetrating downward substantially at the center thereof. The closing part 23 of the elastic bag body 2 includes a convex part 24 that protrudes downward at the center of the bottom part. The convex portion 24 is formed to be slightly larger than the through hole 12. For this reason, the convex part 24 can be easily passed through the through hole 12 by being pushed into the through hole 12, and can be prevented from being easily detached from the through hole 12. The concave portion 11 and the closing portion 23 can be fixed with an adhesive interposed therebetween. Such fixing can make the blocking portion 23 difficult to expand in the radial direction, and as a result, it is possible to suppress the expansion and contraction bag body 2 from being excessively expanded in the radial direction. In addition, the recessed part 11, the through-hole 12, and the convex part 24 are not an essential structure, and do not need to be formed in the base 11 and the elastic bag body 2, respectively.

<Second embodiment>
Next, the injection container according to the second embodiment of the present invention will be described. In 2nd embodiment, about the part which is common in 1st embodiment, the same code | symbol is attached | subjected and the overlapping description is abbreviate | omitted.

  FIG. 3 shows a perspective view (3A) of the spray container according to the second embodiment of the present invention and a perspective view (3B) of the spray container in a state where the cap of the spray container is removed and attached to the bottom.

  The injection container 1a according to the second embodiment is largely different from the injection container 1a according to the first embodiment in that a cap 40 as a holding part is detachably provided in the closing part 23 corresponding to the bottom part of the stretchable bag body 2. Different. The blocking part 23 includes a convex part 24a having a structure similar to that of the convex part 24 described in the first embodiment. The cap 40 also serves as a lid that covers the lid member 3 side (above the actuator 5). The cap 40 includes a recess 41 that is recessed inwardly on the top surface. The concave portion 41 is provided with a through hole 42 penetrating downward substantially at the center thereof. The convex portion 24 a is formed slightly larger than the through hole 42. For this reason, the convex portion 24 a can be easily passed through the through hole 42 by being pushed into the through hole 42, and can be prevented from being easily detached from the through hole 42. In addition, the recessed part 41, the through-hole 42, and the convex part 24a are not an essential structure, and do not need to be formed in the cap 40 and the elastic bag body 2, respectively. In that case, for example, a protrusion may be formed on the top surface of the cap 40, and a recess recessed inward may be formed in the closing portion 23 so that they can be coupled.

  4 shows a perspective view (4A) of a modified example of the spray container of FIG. 3 and a perspective view (4B) of the spray container with the cap of the modified example removed and attached to the bottom.

  The injection container 1b shown in FIG. 4 covers a second cap 50, which is another cap from above the cap 40 that is detachably covered above the actuator 5, and the injection container 1b is placed on the second cap 50. It is a container used as a holding part for holding. That is, it differs from the above-mentioned injection container 1a by using one cap of the double caps covering the lid member 3 side as a holder. The second cap 50 includes a recess 51 that is recessed inwardly on the top surface. The recess 51 is provided with a through hole 52 penetrating downward substantially at the center thereof. The convex portion 24 a is formed to be slightly larger than the through hole 52. For this reason, the convex portion 24 a can be easily passed through the through hole 52 by being pushed into the through hole 52, and can be prevented from being easily detached from the through hole 52. In addition, the recessed part 51, the through-hole 52, and the convex part 24a are not an essential structure, and do not need to be formed in the 2nd cap 50 and the expansion-contraction bag body 2, respectively. In that case, for example, a protruding portion may be formed on the top surface of the second cap 50, and a concave portion recessed inwardly may be formed in the closing portion 23 so that they can be combined. Further, the cap 40 that is the inner cap may be used as the holding portion, and the second cap 50 may be used as a cap that only covers the lid member 3 side. In that case, it is preferable to make the structure of the cap 40 the same structure as the cap 40 of the above-mentioned injection container 1a.

<Third embodiment>
Next, an injection container according to a third embodiment of the present invention will be described. In the third embodiment, parts that are the same as those in each of the above-described embodiments are given the same reference numerals, and redundant descriptions are omitted.

  FIG. 5 is a perspective view (5A) of the injection container according to the third embodiment of the present invention, a perspective view (5B) of the injection container placed on a table or the like, and a state in which the injection container is filled with an inclusion. A perspective view (5C) and a perspective view (5D) in a state where the injection container filled with the inclusions are placed on a table or the like are shown.

  The injection container 1c according to this embodiment includes a plurality of projecting portions 60 and 61 projecting from the side surface of the stretchable bag body 2. In this embodiment, three projecting portions 60 are formed on the surface of the central portion 22 of the stretchable bag body 2, and one projecting portion 61 is formed on the surface of the closing portion 23 of the stretchable bag body 2. As shown in (5D), the projecting portion 60 is mainly configured to prevent the spray container 1c from rolling when the spray container 1c filled with the inclusion 30 is placed on the table G. It is preferable that the protruding portion 60 is not formed in a complete annular shape along the circumference of the stretchable bag body 2 but is formed in a U shape or a C shape lacking a part. The length of the protrusion 60 in the circumferential direction can be appropriately selected according to the expansion / contraction design of the expansion / contraction bag body 2. When the expansion bag 2 filled with the inclusion 30 is expanded more in the radial direction than the lid member 3, if the injection container 1 c is placed sideways on the table G, it may roll and fall off the table G There is. However, when the protrusions 60 are formed, a plane can be formed at three points, that is, the end portions of at least two protrusions 60 and any point on the side surface of the central portion 22 of the stretchable bag body 2. As a result, it is possible to prevent the injection container 1c from rolling. The protrusion 60 may be formed in a completely annular shape along the circumferential direction of the stretchable bag body 2 and a flat surface may be formed on the outer periphery thereof. This is because the plane can prevent the injection container 1c from rolling. Further, only one protrusion 60 may be provided. In that case, a plane can be formed by the end portion of the protruding portion 60 and any two points on the side surface of the central portion 22.

  On the other hand, as shown in (5B), the protruding portion 61 is mainly formed when the injection container 1c that is not filled with the inclusion 30 or has been injected is placed on the table G. It is the structure for preventing from rolling. It is preferable that the protruding portion 61 is not formed in a complete annular shape along the circumference of the stretchable bag body 2 but is formed in a U shape or a C shape lacking a part. Further, the length in the circumferential direction of the protruding portion 61 can be appropriately selected according to the expansion / contraction design of the expansion / contraction bag body 2. Even when the stretchable bag body 2 has a smaller diameter than the lid member 3, if the spray container 1 c is placed on the table G sideways, it may roll and fall from the table G. In this case, the protruding portion 60 formed in the central portion 22 may not contact the table G and may not exhibit the function of preventing the injection container 1c from rolling. When the protruding portion 61 is formed on the surface of the closing portion 23, the end portion of at least one protruding portion 61, an arbitrary point on the side surface of the closing portion 23 of the elastic bag body 2, and an arbitrary point on the lid member 3 A plane can be formed with three points. As a result, it is possible to prevent the injection container 1c from rolling. The protruding portion 61 may be formed in a completely annular shape along the circumferential direction of the stretchable bag body 2 and a flat surface may be formed on the outer periphery thereof. This is because the plane can prevent the injection container 1c from rolling.

  As described above, the expansion bag body 2 is formed with the protrusions 60 and 61 on the outer surface thereof, so that the injection container 1c can be used for the table G regardless of whether the expansion bag body 2 is contracted or expanded. It can be prevented from rolling off. The protrusions 60 and 61 may be formed of the same material as the constituent material of the stretchable bag body 2 or may be formed of a different material. For example, when the elastic bag 2 is made of silicone rubber, the protrusions 60 and 61 may also be made of silicone rubber. In that case, the protrusions 60 and 61 can be formed by integral molding at the time of manufacturing the stretchable bag body 2, or can be formed in a separate process from the stretchable bag body 2 and bonded to the stretchable bag body 2. . When the stretchable bag body 2 is made of silicone rubber, the protrusions 60 and 61 may be made of a harder resin such as polycarbonate. In that case, as in the previous example, the protrusions 60 and 61 can be integrally formed or separately formed and bonded to the stretchable bag body 2. Furthermore, the protrusions 60 and 61 are only an example of a holding unit for holding the injection container 1c on the place (table G in this embodiment), and can be substituted for other forms.

  6 is a perspective view (6A) of a modification of the injection container shown in FIG. 5, a perspective view (6B) of the modification placed on a table or the like, and the injection container of the modification is filled with an inclusion. A perspective view (6C) of the state and a perspective view (6D) of the state in which the injection container of the modification filled with the inclusions are placed on a table or the like are shown.

  The injection container 1d according to this modification includes a single protrusion 65 that is elongated in the length direction on the side surface of the elastic bag body 2. In this embodiment, the protruding portion 65 is formed so as to protrude outward in the radial direction of the stretchable bag body 2 from the central portion 22 to the closing portion 23 of the stretchable bag body 2. As shown in (6D), the portion present in the central portion 22 of the projecting portion 65 mainly prevents the injection container 1d from rolling when the injection container 1d filled with the inclusion 30 is placed on the table G. It is the structure for making. The protrusion 65 may be a single molded body in the central portion 22 or may be composed of two or more molded bodies that are separately disposed. Further, the length, width, and thickness of the protrusion 65 can be appropriately selected according to the expansion / contraction design of the expansion / contraction bag body 2. When the expansion bag 2 filled with the inclusion 30 is expanded more in the radial direction than the lid member 3, if the injection container 1 d is placed sideways on the table G, it may roll and fall off the table G There is. However, if the protruding portion 65 is formed in the central portion 22, a plane can be formed from the side of the protruding portion 65 and the side on the side surface of the central portion 22 of the stretchable bag body 2. As a result, it is possible to prevent the spray container 1d from rolling. Note that a plurality of protrusions 65 may be formed in the circumferential direction of the stretchable bag body 2. This can further prevent the spray container 1d from rolling.

  On the other hand, as shown in (6B), the portion of the protruding portion 65 existing in the closed portion 23 is mainly placed on the table G with the injection container 1d not filled with the inclusion 30 or after being injected. This is a configuration for preventing the spray container 1d from rolling when placed. The protruding portion 65 may be a single molded body in the closing portion 23 or may be composed of two or more molded bodies that are separately disposed. Further, the length, width, and thickness of the protrusion 65 can be appropriately selected according to the expansion / contraction design of the expansion / contraction bag body 2. Even when the stretchable bag body 2 has a smaller diameter than the lid member 3, if the injection container 1 d is placed on the table G sideways, it may roll and fall from the table G. In this case, the protruding portion 65 present in the central portion 22 hardly contacts the table G, and may not function to prevent the ejection container 1d from rolling. Therefore, when the protruding portion 65 is formed on the surface of the closing portion 23, a plane is formed from the side of the protruding portion 65, the side or point on the side surface of the closing portion 23 of the stretchable bag body 2, and an arbitrary point of the lid member 3. Can be formed. As a result, it is possible to prevent the spray container 1d from rolling.

<Fourth embodiment>
Next, an injection container according to a fourth embodiment of the present invention will be described. In the fourth embodiment, portions common to the above-described embodiments are assigned the same reference numerals, and redundant description is omitted.

  FIG. 7 shows a perspective view (7A) of the injection container according to the fourth embodiment of the present invention and a perspective view (7B) in a state where the injection container is filled with the inclusion.

  The injection container 1e according to this embodiment includes a tripod 70 that can be expanded and contracted as a holding unit for holding the injection container 1e at a place where the injection container 1e is placed. The tripod 70 is preferably formed so as to surround the outer side of the elastic bag body 2 from the side surface of the lid member 3 and to expand outward in the radial direction. As shown in (7A), in a situation where the stretchable bag body 2 is contracted, the movable portion 71 existing below each leg of the tripod 70 is in a state where a part is accommodated in the cylinder of each leg. . On the other hand, as shown in (7B), in a situation where the elastic bag body 2 is inflated, the movable part 71 of the tripod 70 is in a state of protruding from each leg. That is, the projecting length of the movable portion 71 of the tripod 70 can be varied according to the degree of expansion of the stretchable bag body 2. In this embodiment, the movable part 71 is configured to be simply housed inside each cylindrical leg. However, an elastic part such as a spring is arranged on each leg so that the movable part 71 is elastic to the elastic part. You may design so that it may resist and shrink. It is preferable that the space formed by the tripod 70 is sufficiently large so as not to inhibit the expansion of the elastic bag body 2 in consideration of the volume when the expansion bag body 2 is expanded to the maximum extent. The tripod 70 may be attached to the central portion 22 or the closed portion 23 of the elastic bag body 2. In that case, it is preferable to attach the tripod 70 to a rubber belt that can be stretched along the circumference of the stretchable bag body 2.

<Fifth embodiment>
Next, an injection container according to a fifth embodiment of the present invention will be described. In the fifth embodiment, portions common to the above-described embodiments are denoted by the same reference numerals, and redundant description is omitted.

  FIG. 8 is a longitudinal sectional perspective view (8A) when the spray container according to the fifth embodiment of the present invention is longitudinally cut along a surface similar to the surface S of FIG. 1, and a modification of the spray container shown in 8A above. The longitudinal cross-sectional perspective view (8B) when cut | disconnected longitudinally at a surface, and the longitudinal cross-sectional perspective view (8C) when cut | disconnecting vertically further by the said surface are shown, respectively.

  The injection container 1f shown in (8A) includes a core member 80 inside the stretchable bag body 2. The core member 80 is not limited to its constituent material, and is preferably made of a material that is harder and less stretchable than the stretchable bag body 2. For example, when the elastic bag body 2 is formed of rubber, the core member 80 is preferably made of a resin, metal, ceramics, or the like harder than rubber. The core member 80 is preferably fixed to the back side of the lid member 3, and there is no restriction on the fixing method. For example, the upper portion of the core member 80 may be bonded to the back surface of the lid member 3. Further, a part of the core member 80 may be fixed to the lid member 3 by a method in which a part of the core member 80 is screwed into a portion immediately below the valve 6 on the back side of the lid member 3. When the core member 80 is disposed inside the stretchable bag body 2, the space when the stretchable bag body 2 contracts can be reduced by the volume of the core member 80, so that the remaining amount of the inclusion 30 can be reduced. . Further, when the inclusion 30 is reduced, and it is difficult to inject the inclusion 30 to the outside only with the internal pressure and the elastic restoring force of the elastic bag body 2, the core member 80 is gripped from the outside of the elastic bag body 2, and the lid member 3. By squeezing the elastic bag 3 toward the side, the remaining inclusion 30 can be taken out. Even if the core member 80 does not exist, such an operation is possible, but if the core member 80 harder than that is present inside the stretchable bag body 2, the stretchable bag body 2 is not folded. However, it is easy to take out the enclosure 30 to the outside.

  The core member 80 has a through passage 81 extending from the upper surface to the side surface. The through path 81 is a path that connects between the outside and the inside of the elastic bag body 2. When filling the enclosure 30 from the outside and injecting the enclosure 30 from the inside of the elastic bag body 2 to the outside, the through-passage 81 functions as a path through which the enclosure 30 passes. The through path 81 may be a path that penetrates from the top surface to the bottom surface, in addition to the top surface to the side surface of the core member 80. However, when the core member 80 is grasped from the outside of the elastic bag body 2 and the inclusion 30 is forcibly sent to the lid member 3 side, the opening of the through-passage 81 is the side surface as high as possible of the core member 80. Is preferred. This is because it is easier to put out the inclusion 30 to the outside if the entrance of the through-passage 81 is present near the downstream side where the inclusion 30 is forcibly sent.

  The injection container 1g shown in (8B) can also include a core member 85 having one or a plurality of grooves 86 that are recessed in an annular or spiral shape toward the inside in the radial direction. The configuration of the core material 85 other than the groove 86 is the same as the configuration of the core material 80 described above. When the groove 86 is formed in the core member 85, there is an advantage that the core member 85 can be easily gripped from the outside of the stretchable bag body 2.

  The injection container 1h shown in (8C) includes an annular or spiral convex portion 88 on the outer surface of the stretchable bag body 2. The structure of the injection container 1h other than the convex portion 88 is the same as that of the injection container 1g described above. When the convex portion 88 is formed on the outer surface of the stretchable bag body 2, there is an advantage that the core member 85 can be easily gripped from the outside of the stretchable bag body 2.

The other of the display portions 91 and 92 is a first display when the stretchable bag body 2 is contracted. The second display unit 92 is easier to visually recognize than the unit 91. The first display unit 91 may or may not be visible with the human eye when the elastic bag body 2 is contracted, but is a display unit that is difficult to visually recognize in the relative evaluation with the second display unit 92. On the other hand, the second display unit 92 may or may not be visible with the human eye when the stretchable bag body 2 is inflated, but is a display unit that is difficult to visually recognize in the relative evaluation with the first display unit 91. . The first display portion 91 and the second display portion 92 correspond to a plurality of display portions that complement each other with ease of visual recognition according to the degree of expansion and contraction of the elastic bag body 2. However, both the first display portion 91 and the second display portion 92 may be visible at a predetermined degree of expansion of the stretchable bag body 2. In addition, it is preferable to avoid the form in which both the first display unit 91 and the second display unit 92 are difficult to visually recognize as much as possible.

  The two types of display portions 91 and 92 are provided in the stretchable bag body 2 because, when a label on which information on products or companies is printed or pasted on a stretchable container, the above-mentioned information is visually recognized depending on the degree of stretch. Because sex also changes. When the expansion bag body 2 is provided with the two types of display portions 91 and 92 as described above, even if the filling amount of the inclusion 30 changes and the size of the expansion bag body 2 changes, the first display portion 91 or At least one of the second display portions 92 is easily visible with human eyes.
