The top wall portion 31 is formed with an intake hole 31 c for supplying air toward the outside air introduction hole 15.

  The inner plug 40 is mounted on the inside of the discharge cap 30 and covers the opening of the mouth portion 11 and the mounting cap 20. The inner plug 40 is made of a synthetic resin, and includes an annular partition wall portion 41 disposed at an axial interval with respect to the top wall portion 31 inside the discharge cap 30, and an outer peripheral edge of the partition wall portion 41. The outer cylinder part 42 extended toward the top wall part 31 side, and the inner cylinder part 43 extended toward the top wall part 31 side from the inner periphery of the partition part 41 are provided. An air groove 41 b that constitutes a part of the air flow path 60 is formed at the outer edge of the partition wall 41.

  The outer cylinder part 42 abuts the lower end of the top wall part 31 at its upper end and is fitted to the inner surface of the cylinder wall part 32 at the outer peripheral part, whereby the inner plug 40 is fixedly held inside the discharge cap 30. . The outer cylinder part 42 is provided with a communication groove 42 a that constitutes the air flow path 60.

  Further, the upper end of the inner cylinder portion 43 is in contact with the lower surface of the top wall portion 31 and is fitted to the outer surface of the holding cylinder 31b. The partition wall portion 41 is provided with an annular seal tube portion 44 integrally, and the seal tube portion 44 is fitted to the inner peripheral surface of the upper tube portion 24. The inner plug 40 is covered with a discharge cap 30.

  A circular through hole 41a is provided at the center of the partition wall 41 of the inner plug 40, and the check valve structure 50 (check valve structure) closes the through hole 41a.

  The check valve structure 50 is formed of a soft material such as rubber or elastomer, for example, and has a cylindrical fixing portion 51, a first valve portion 52 located on one end side of the fixing portion 51, and the other end of the fixing portion 51. 2nd valve part 53 located in the side, and the flange part 54 which protrudes from the outer peripheral surface of the fixed part 51 are provided. In the present embodiment, the check valve structure 50 is integrally formed as one member. However, the present invention is not limited to this, and a combination of a plurality of members such as a vertically divided structure may be used.

  The fixing part 51 forms a flow path of the contents when discharging the contents. That is, when discharging the contents, the contents in the storage space S pass through the inside of the fixed portion 51 and move to the discharge port 33.

  The liquid storage space L surrounded by the fixed portion 51, the first valve portion 52, and the second valve portion 53 serves as a flow path for the content when discharging the content liquid. Further, a part of the remaining content is stored in the liquid storage space L after the content is discharged, thereby covering almost the entire first valve portion 52 and sealing the slit 52a. That is, the content liquid stored in the liquid storage space L can constitute a so-called liquid seal and suppress the intrusion of outside air into the storage space S.

  The first valve portion 52 is a check valve having a slit valve structure provided so as to cover the opening on the accommodation space S side in the fixed portion 51, and allows the flow of contents from the accommodation space S side toward the discharge port 33. In addition, the flow of contents from the discharge port 33 side toward the accommodation space S is prevented. In this example, as shown in FIG. 1, the first valve portion 52 has a dome shape that bulges from the accommodation space S side toward the discharge port 33 side. The first valve portion 52 is formed with two orthogonal slits 52a. As shown in FIG. 2, when the contents are discharged, the first valve portion 52 is elastically deformed to open the slit 52a. The contents can be passed. The first valve portion 52 is not limited to a dome shape, and may be a flat shape or a dome shape that bulges from the discharge port 33 side toward the accommodation space S side, contrary to the illustrated example. is there. Moreover, the slit 52a may be one and may be three or more.

  The 2nd valve part 53 is provided so that the opening by the side of the discharge outlet 33 in the fixing | fixed part 51 may be covered. In the present example, as shown in FIG. 1, the second valve portion 53 has a dome shape that bulges from the accommodation space S side toward the discharge port 33 side, and has a substantially circular hole 53a in plan view. In addition, the 2nd valve part 53 is good also as a slit valve structure which provided the slit like the 1st valve part 52 instead of the hole 53a.

  The flange portion 54 is sandwiched and held between an inward flange 43a that protrudes radially inward from the inner tube portion 43 of the inner plug 40 and a holding tube 31b of the discharge cap 30. Thus, the check valve structure The body 50 is held between the inner plug 40 and the discharge cap 30.

  As shown in FIG. 1, between the discharge cap 30 and the mouth portion 11, the outside air introduction hole 15 provided in the mouth portion 11 communicates with the communication hole 21 c provided in the outer peripheral wall portion 21, An air flow path 60 that can communicate with the outside of the discharge cap 30 is defined by an air groove 41 b and a communication groove 42 a provided in the stopper 40 and an intake hole 31 c provided in the top wall portion 31. Note that the lower portion of the cylindrical wall portion 32 is in airtight contact with the sealing step portion 11b over the entire circumference. Further, a slit extending in the vertical direction is formed in the male screw 11a, and a part of the air flow path 60 is configured by the slit in a portion where the male screw 11a and the female screw 21a are provided. In addition, you may make it distribute | circulate air along the external thread 11a and the internal thread 22a, without providing a slit in the external thread 11a.

  The discharge cap 30 can also be configured to include a lid 70. In the case shown in the drawing, the lid body 70 is formed in a top tube shape having substantially the same diameter as the discharge cap 30, and is connected to the top wall portion 31 of the discharge cap 30 by a hinge 71 and is discharged together with the top wall portion 31. 31a can be covered. A crested cylindrical seal member 72 is attached to the inner surface of the lid body 70. When the lid body 70 is closed, the outer peripheral surface of the seal member 72 is fitted to the inner peripheral surface of the discharge cylinder 31a and the discharge port. 33 is closed. On the side of the lid 70 facing the hinge 71, a knob 73 is provided as a finger hook when the lid 70 is opened. In this example, the seal member 72 is a separate member from the lid 70, but the present invention is not limited to this, and the lid 70 and the seal member 72 may be integrally formed.

  The lid body 70 is not limited to the structure integrally connected to the discharge cap 30 by the hinge 71, but may be configured to be formed separately from the discharge cap 30 and attached to the discharge cap 30 by screwing or undercutting. .

  In the discharge container 1 having such a configuration, the slit 12a of the first valve part 52 is formed by squeezing the body part 12 while tilting the container body 10 so that the discharge cylinder 31a faces downward with the lid 70 opened. Is opened, and the contents in the storage space S can be discharged from the discharge port 33 through the slit 52a, the fixed portion 51 (the liquid storage space L), and the hole 53a. Here, in this embodiment, when the body 12 is squeezed by forming a region (air groove 41b or the like) that is partially narrowed in the air flow path 60, the space between the outer layer body 13 and the inner layer body 14 is increased. The structure is such that the air present in the is difficult to leak out. Thereby, by squeezing the trunk portion 12 of the outer layer body 13, the inner layer body 14 can be pressed and the contents can be pushed out toward the discharge port 33. The air flow path 60 allows a flow of air from the intake hole 31c to the outside air introduction hole 15, and prevents an air flow from the outside air introduction hole 15 to the intake hole 31c. It is also possible to provide. By setting it as such a structure, it can suppress more reliably that the air which exists between the outer layer body 13 and the inner layer body 14 leaks outside at the time of a squeeze.

  Then, when the squeeze to the body portion 12 is released after the contents are discharged, the first valve portion 52 is closed and a part of the remaining contents is stored in the fixed portion 51 as shown in FIG. A liquid seal is configured by being stored in the space L. Even if a solid substance contained in the contents is caught in the slit 52a of the first valve portion 52, the contents are maintained in the liquid storage space L without leaking because of the high viscosity of the contents. Since the 1 valve part 52 is sealed, outside air does not enter the accommodation space S. Here, in order to exhibit the function of the check valve structure 50 more reliably, the viscosity of the content is preferably in the range of 1000 mPa · s to 100000 mPa · s, and the solid matter contained in the content The diameter of is preferably about 0.5 mm to 2 mm in diameter.

  Further, from the viewpoint of maintaining the contents in the liquid storage space L and more reliably exhibiting the function of the check valve structure 50, the volume of the liquid storage space L is preferably about 0.2 ml to 2 ml. Each of the lengths 52a is preferably 3 mm to 5 mm.

  The hole 53a may be set to a size that prevents the contents from leaking even when the container body 10 is turned upside down while the contents are accumulated in the fixed portion 51, and does not make it difficult to discharge the contents during ejection. preferable. Specifically, the size of the hole 53a is preferably 3 mm to 4 mm in diameter.

  When the outer layer body 13 is restored by releasing the squeeze to the body portion 12, outside air is introduced between the inner layer body 14 and the outer layer body 13 through the air passage 60 from the intake hole 31c. The outer layer body 13 can be restored to its original shape while the inner layer body 14 is deformed and reduced in volume. Therefore, it can suppress that external air is introduce | transduced into the storage space S, can reduce the contact with the air of the content accommodated in the container main body 10, and can suppress the quality change and deterioration of the content.

  Here, in this embodiment, the 1st valve part 52 is made into the dome shape which bulges toward the discharge port 33 side from the accommodation space S side, Therefore A content moves from the accommodation space S side to the discharge port 33 side. It is easy to open in the direction of heading, and difficult to open in the direction of backflow from the discharge port 33 side toward the accommodation space S side. Accordingly, the force applied to squeeze the body portion 12 can be reduced, and the contents in the liquid reservoir space L can hardly be moved to the storage space S, thereby improving the sealing performance of the liquid seal.

  Further, since the second valve portion 53 has a structure in which a hole 53a is provided instead of a slit, the contents can easily pass through compared to the case where the second valve portion 53 has a slit valve structure, and the force applied during squeeze is small. Become. Furthermore, compared to the case where the second valve portion 53 has a slit valve structure, the structure in which the hole 53a is provided makes it easy to adjust the flow of the contents passing through the hole 53a of the second valve portion 53, and the discharge. It is difficult for the contents to be scattered.

  Moreover, in this embodiment, the fixed part 51, the 1st valve part 52, and the 2nd valve part 53 were integrally formed, For example, compared with the structure divided | segmented up and down, the number of parts can be reduced.

  In addition, when using the discharge container 1 for the content with comparatively high viscosity, it is preferable that the cover body 70 is a shape which can mount the discharge container 1 in an inverted posture. With this configuration, the contents of the storage space S are arranged in advance on the discharge port 33 side due to gravity, so that the contents are discharged immediately after opening the lid 70 and squeezing the body 12 during use. It becomes easy to be done.

  Further, in the discharge container 1 of the present embodiment, it is easy to take in the outside air by providing a partially narrow area in the air channel 60 without providing the air channel 60 with a check valve for introducing the outside air. It is preferable to adjust the thickness. With such a configuration, it is easy to take in outside air between the outer layer body 13 and the inner layer body 14 via the air flow path 60 when the outer layer body 13 is restored after the squeeze to the body portion 12 is released. Therefore, when the outer layer body 13 is restored, the space between the outer layer body 13 and the inner layer body 14 becomes negative pressure, so that the inner layer body 14 expands and the outside air enters the accommodation space S. It becomes easy.

  It goes without saying that the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention. For example, in the above embodiment, the container body 10 is a laminated peeling container in which the inner layer body 14 is laminated on the inner surface of the outer layer body 13 so that the inner layer body 14 can be peeled, but the inner layer body 14 is not limited to this. It is good also as a built-in type double container built in. Furthermore, the container body 10 is not limited to a double container including the outer layer body 13 and the inner layer body 14, and can be formed into a normal container that does not include the inner layer body 14. In this case, a configuration in which the outside air introduction hole 15, the intake hole 31c, the air flow path 60, and the like are not provided can be employed.
