Description

  The present invention relates to a foam discharge container.

2. Description of the Related Art Conventionally, a configuration including a former pump is known as a foam discharge container that foams and discharges contents. In this foam discharge container, the number of parts increases and the cost increases, and there are cases where the filling equipment for contents is limited and the manufacturing cost increases.
As means for solving such a problem, for example, as shown in Patent Document 1, in a container in which a cap body is simply attached to a container body, the contents are foamed by shaking the container, and the contents It is conceivable to discharge bubbles of objects.

Japanese Utility Model Publication No. 63-144466

  However, in this case, if the container body is tilted so that the mouth is directed downward, the unfoamed contents that are not foamed in the container body move downward and are discharged from the cap body, so only the foam is discharged. It was difficult to do.

  This invention is made | formed in view of the situation mentioned above, Comprising: The foam discharge container which can discharge a foam with a simple structure is provided.

In order to solve the above problems, the present invention proposes the following means.
The foam discharge container according to the present invention is provided with a container main body in which a container for storing contents is formed, and a discharge hole that is attached to the mouth of the container main body and discharges the foamed contents. A foam discharge container comprising: a cap body; an intake hole formed in the cap body for sucking outside air; a discharge passage formed in at least the container body and communicating the inside of the housing portion with the discharge hole; A shut-off portion that shuts off communication between the opening on the mouth side of the housing portion and the discharge hole, an intake passage that is formed at least in the shut-off portion and communicates the inside of the housing portion with the intake hole, and the discharge When the positive pressure in the accommodating portion is provided in the passage, the inside of the accommodating portion and the discharge hole are communicated with each other through the discharge passage, and in the accommodating portion through the discharge passage at the negative pressure in the accommodating portion, and the Communication with the discharge hole A discharge valve to be cut off, and disposed in the intake passage, and when the positive pressure in the accommodating portion is blocked, the communication between the accommodating portion and the intake hole through the intake passage is interrupted, and when the negative pressure is in the accommodating portion And an intake valve that communicates the inside of the housing and the intake hole through the intake passage.

According to the present invention, for example, the container body is tilted so that the mouth portion faces downward in a state in which a part of the contents in the container is foamed by shaking the container body. Then, the unfoamed content moves to the mouth side in the accommodating portion, and the foamed content is positioned on the liquid level of the unfoamed content. At this time, the blocking portion blocks communication between the opening on the mouth side in the housing portion and the discharge hole. Therefore, even if unfoamed contents are accumulated on the mouth side in the accommodating portion, the contents are prevented from flowing into the ejection holes through the opening on the mouth side, and the contents are ejected from the ejection holes. This can be suppressed.
When discharging the foamed contents as bubbles, the container body is squeezed and deformed to a positive pressure with the container body tilted as described above. At this time, the discharge valve communicates the inside of the housing portion and the discharge hole through the discharge passage. Therefore, foam can be discharged from the discharge hole by allowing the foamed contents to enter the discharge passage. At this time, the intake valve shuts off the communication between the inside of the housing portion through the intake passage and the intake hole. Therefore, it is possible to suppress the contents in the housing portion from leaking through the intake hole.
Thereafter, when the container body that has been squeezed and deformed is deformed and deformed using, for example, the elastic restoring force of the container body, the inside of the housing portion becomes negative pressure. At this time, the intake valve communicates the inside of the housing portion with the intake hole through the intake passage. Therefore, outside air can be sucked into the accommodating portion through the intake hole and the intake passage. Thereby, the container main body can be smoothly restored and deformed. In addition, the air sucked into the accommodating portion from the intake passage can be mixed with the unfoamed contents in the accommodating portion, and the contents can be foamed. Further, at this time, the discharge valve blocks communication between the inside of the housing portion through the discharge passage and the discharge hole. Therefore, it is possible to suppress the foamed contents entering the discharge passage from being returned to the storage portion.
As described above, when the container body that has undergone squeeze deformation is restored and deformed, the foamed contents in the discharge passage can be prevented from returning to the containing part while foaming the unfoamed contents in the containing part. Therefore, foam can be continuously discharged from the discharge hole by squeezing the container body again.
As described above, according to this foam discharge container, it is possible to discharge foam with a simpler configuration than, for example, a foam discharge container including a former pump.
Further, when the container body is restored and deformed in the course of the foam discharge operation, the unfoamed contents can be foamed by sucking air from the intake passage into the accommodating portion. Therefore, if the content is foamed by a certain amount at the start of ejection, it is possible to continuously eject the foam from the ejection holes even if the amount of foaming is small.
By the way, if the amount of foaming of the contents at the start of discharge can be reduced, the volume of the space that needs to be secured in the housing portion for foaming of the contents can be reduced. Therefore, a larger amount of contents can be accommodated in the accommodating portion in the unused foam discharge container.

  A circumferential position that circulates around the cap axis in the discharge hole may be different from a circumferential position of the opening on the accommodating portion side in the discharge passage.

  In this case, the circumferential position of the discharge hole and the circumferential position of the opening on the accommodating portion side in the discharge passage are different from each other. Therefore, when the container body is tilted, for example, by positioning the discharge hole directly below the cap shaft, the opening on the container side in the discharge passage can be more easily positioned. As a result, it is possible to prevent the unfoamed content from flowing into the discharge passage in the accommodating portion, and to easily introduce the foamed content into the discharge passage.

  A first foaming member may be disposed in at least one of a portion of the discharge passage located on the discharge hole side of the discharge valve and the discharge hole.

  In this case, the first foaming member is disposed in at least one of the portion located on the discharge hole side of the discharge valve and the discharge hole in the discharge passage. Therefore, after the foamed content passes through the discharge valve in the discharge passage, it passes through the first foaming member before being discharged from the discharge hole. At this time, the gas component and the liquid component in the foamed contents are remixed by the first foam member. Thereby, the foam quality of the content discharged from the discharge hole can be improved.

  A second foaming member may be disposed in a portion of the intake passage that is located closer to the accommodating portion than the intake valve.

  In this case, the second foaming member is disposed in a portion of the intake passage that is located closer to the accommodating portion than the intake valve. Therefore, when the air sucked from the intake hole passes through the second foaming member, the content can be effectively foamed by mixing the air and the content.

  The container body is formed in a flat shape that is smaller in the minor axis direction than the major axis direction in a cross-sectional view orthogonal to the cap axis, and the discharge hole and the intake hole are shifted in the minor axis direction. May be.

  In this case, the discharge holes and the intake holes are arranged so as to be shifted in the minor axis direction. Therefore, for example, when the container body is tilted after holding the container body so as to be sandwiched between the thumb of one hand and the other finger in the short axis direction, the discharge hole is easily positioned below the intake hole. can do. Thereby, it can suppress that the foam discharged from the discharge hole covers an inlet hole. As a result, it is possible to suppress the discharged contents from being unintentionally sucked into the housing portion through the suction hole.

  The container main body is formed with a passage portion that is independent from the housing portion, and the passage portion forms a part of the discharge passage and passes through a passage hole that is an opening on the housing portion side of the discharge passage. You may communicate in the said accommodating part.

  In this case, the inside of the passage portion is independent of the housing portion and forms a part of the discharge passage, and communicates with the housing portion through the passage hole. Therefore, the foamed contents in the accommodating portion can be smoothly distributed toward the discharge hole by entering the discharge hole from the passage hole and the passage portion.

  The passage portion protrudes outward from the container main body and extends in the cap axial direction, and the passage hole communicates the end portion on the bottom side along the cap axial direction in the passage portion and the inside of the housing portion. May be.

  In this case, the passage hole communicates the end portion on the bottom side of the passage portion with the inside of the accommodating portion. Therefore, when the container body is tilted so that the mouth portion faces downward, the passage hole can be easily positioned upward. As a result, it is possible to prevent the unfoamed content from flowing into the discharge passage in the accommodating portion, and to easily introduce the foamed content into the discharge passage.

  The intake valve 75 is seated on the second valve seat portion 76 so as to be separated toward the housing portion 30 side. The second valve seat portion 76 is provided in the first intake cylinder portion 48. The second valve seat 76 projects from the first intake cylinder 48 toward the inside in the radial direction of the first intake cylinder 48. The second valve seat 76 is formed in an annular shape that is coaxial with the first intake cylinder 48 (cap shaft O). The intake valve 75 is positioned below the second valve seat portion 76 and is seated on the second valve seat portion 76 from below.

  The second restricting portion 77 restricts the amount of separation of the intake valve 75 from the second valve seat portion 76. The second restricting portion 77 includes a plurality of second vertical ribs 79. The second vertical rib 79 is provided on the inner peripheral surface of the first intake cylinder portion 48.

  An upper end portion of the second vertical rib 79 is a second locking portion 80. The second locking portion 80 protrudes inward in the radial direction of the first intake cylinder portion 48. When the second locking portion 80 is locked to the intake valve 75 from the accommodating portion 30 side, further separation of the intake valve 75 from the second valve seat portion 76 is restricted.

  The second foam member 78 is disposed in a portion of the intake passage 66 that is located closer to the accommodating portion 30 than the intake valve 75. The second foam member 78 is fitted in the lower end portion of the first intake cylinder portion 48. The second foam member 78 includes a second cylindrical body 81 and a second mesh body 82. The second cylindrical body 81 opens toward both sides in the cap axis O direction. The second mesh body 82 is stretched around the opening edge of the second cylindrical body 81. The 2nd mesh body 82 is provided in the opening edge by the side of the accommodating part 30 among the two opening edges of the 2nd cylindrical body 81. As shown in FIG.

  The operation of the foam discharge container 10 will be described.

  When the foam is discharged from the discharge hole 41, as shown in FIG. 8, the lid 45 is rotated in a state in which a part of the contents M in the container 30 is foamed by, for example, shaking the container body 20. The main body 44 is opened, and the container main body 20 is tilted so that the mouth portion 21 faces downward. Then, the unfoamed content M moves to the mouth portion 21 side in the accommodating portion 30, and the foamed content M is located on the liquid level of the unfoamed content M.

  At this time, the blocking portion 43 blocks communication between the opening 31 on the mouth portion 21 side and the discharge hole 41 in the housing portion 30. Therefore, even if the unfoamed content M is accumulated on the mouth 21 side in the accommodating portion 30, the content M is prevented from flowing into the discharge hole 41 through the opening 31 on the mouth 21 side. It can suppress that the thing M is discharged from the discharge hole 41. FIG.

  When discharging the foamed contents M as foam, the container body 20 is squeezed and deformed to a positive pressure in the container body 20 with the container body 20 tilted as described above. At this time, as shown in FIG. 9, the discharge valve 67 communicates the inside of the accommodating portion 30 and the discharge hole 41 through the discharge passage 65. Therefore, bubbles can be discharged from the discharge holes 41 by allowing the foamed contents M to enter the discharge passage 65. That is, the foamed content M flows through the passage hole 32, the second bulging portion 28b, the connection cylinder portion 33, the first discharge cylinder portion 49, the discharge space 55, and the second discharge cylinder portion 57, and is discharged. It is discharged from the hole 41 as bubbles.

  At this time, the intake valve 75 blocks communication between the inside of the housing portion 30 through the intake passage 66 and the intake hole 42. Therefore, it is possible to suppress the content M in the housing portion 30 from leaking through the intake hole 42.

  Thereafter, as shown in FIG. 10, when the container body 20 that has undergone squeeze deformation is deformed and deformed using, for example, the elastic restoring force of the container body 20, the inside of the housing portion 30 becomes negative pressure. At this time, as shown in FIG. 11, the intake valve 75 communicates the inside of the accommodating portion 30 and the intake hole 42 through the intake passage 66. Therefore, outside air can be sucked into the accommodating portion 30 through the intake hole 42 and the intake passage 66. That is, outside air is sucked into the accommodating portion 30 through the intake hole 42, the second intake cylinder portion 56, and the first intake cylinder portion 48. Thereby, the container main body 20 can be smoothly restored and deformed. In addition, the air sucked into the housing portion 30 from the intake passage 66 can be mixed with the unfoamed content M in the housing portion 30 to foam the content M.

  At this time, the discharge valve 67 blocks communication between the inside of the housing portion 30 through the discharge passage 65 and the discharge hole 41. Therefore, it is possible to suppress the foamed contents M entering the discharge passage 65 from being returned to the storage unit 30.

  As described above, when the container body 20 that has undergone squeeze deformation is restored and deformed, the foamed content M in the discharge passage 65 is returned into the storage unit 30 while foaming the unfoamed content M in the storage unit 30. Can be suppressed. Therefore, the foam can be continuously discharged from the discharge hole 41 by squeezing the container body 20 again.

  As described above, according to the foam discharge container 10 according to the present embodiment, it is possible to discharge foam with a simple configuration as compared with, for example, a foam discharge container including a former pump.

In addition, when the container body 20 is restored and deformed in the course of the foam discharge operation, the unfoamed contents M can be foamed by sucking air into the housing portion 30 from the intake passage 66. Therefore, if the content M is foamed by a certain amount at the start of ejection, the foam can be continuously ejected from the ejection holes 41 even if the amount of foaming is small.
By the way, if the amount of foaming of the contents M at the start of discharge can be reduced, the volume of the space that needs to be secured in the accommodating portion 30 for foaming of the contents M can be reduced. Therefore, a larger amount of contents M can be accommodated in the accommodating portion 30 in the unused bubble discharge container 10.

  Further, the circumferential position of the discharge hole 41 and the circumferential position of the passage hole 32 are different from each other. Therefore, when the container body 20 is tilted, for example, the discharge hole 41 is positioned directly below the cap axis O, so that the passage hole 32 can be easily positioned higher. As a result, it is possible to prevent the unfoamed content M from flowing into the discharge passage 65 in the accommodating portion 30 and to easily introduce the foamed content M into the discharge passage 65.

  Further, the first foam member 70 is disposed in at least one of the discharge passage 65 and the portion located on the discharge hole 41 side of the discharge valve 67 and the discharge hole 41. Therefore, after the foamed content M passes through the discharge valve 67 in the discharge passage 65 and passes through the discharge hole 41, it passes through the first foam member 70. At this time, the gas component and the liquid component in the foamed contents M are remixed by the first foam member 70. Thereby, the foam quality of the content M discharged from the discharge hole 41 can be improved. Furthermore, it is possible to discharge finer bubbles using a plurality of first foam members 70 including first mesh bodies 74 having different roughnesses.

  A second foam member 78 is disposed in a portion of the intake passage 66 that is located closer to the accommodating portion 30 than the intake valve 75. Therefore, when the air sucked from the suction hole 42 passes through the second foaming member 78, the content M can be effectively foamed by mixing the air and the content M.

  Further, the discharge hole 41 and the intake hole 42 are arranged so as to be shifted in the short axis direction D2. Therefore, for example, when the container body 20 is tilted after being gripped so that the container body 20 is sandwiched between the thumb and other fingers of one hand in the short axis direction D2, the discharge hole 41 is easier than the intake hole 42. Can be positioned below. Thereby, it is possible to suppress the bubbles discharged from the discharge holes 41 from covering the intake holes 42. As a result, the discharged content M can be prevented from being unintentionally sucked into the housing portion 30 through the suction hole 42.

  Further, the inside of the second bulging portion 28 b is independent of the housing portion 30 and forms a part of the discharge passage 65, and communicates with the housing portion 30 through the passage hole 32. Therefore, the foamed contents M in the accommodating portion 30 can be smoothly circulated toward the discharge hole 41 by entering the discharge passage 65 from the passage hole 32 and the second bulging portion 28b.

  Furthermore, the passage hole 32 communicates the inside of the lower end portion of the second bulging portion 28 b and the inside of the accommodating portion 30. Therefore, when the container main body 20 is tilted so that the mouth portion 21 faces downward, the passage hole 32 can be easily positioned upward. As a result, it is possible to prevent the unfoamed content M from flowing into the discharge passage 65 in the accommodating portion 30 and to easily introduce the foamed content M into the discharge passage 65.
