(Description of the operation of the first embodiment)
The dispenser 1 and the container 100 according to the first embodiment are configured as described above, and the operation thereof will be described below.

  When the dispenser 1 is attached to the container body 101, the seal 106 is peeled off from the opening end face of the opening 102 of the container body 101 in which the liquid content 105 is accommodated, and the first check valve 81 and the second check valve of the dispenser 1 are removed. 82, the supply pipe 4 and the air intake pipe 7 are put into the container body 101 from the opening of the opening 102. And the internal thread of the attachment part 2 of the dispenser 1 is screwed into the external thread 107 of the opening part 102 of the container main body 101, and the dispenser 1 is attached to the container main body 101 so that attachment or detachment is possible. Thereby, the container 100 is comprised.

  When the container 100 is in the upright state shown in FIG. 1, the liquid content 105 in the container 100 is positioned on the bottom 103 side of the container main body 101 due to gravity, and the air 109 in the container 100 is in the opening 102 of the container main body 101. Located on the side. In the first embodiment, either the upright state or the inverted state may be used in use. However, when the container 100 is in the inverted state shown in FIG. The air 109 in the container 100 is located on the bottom 103 side of the container main body 101. In the inverted state of the container 100, the body portion 104 of the container body 101 is squeezed with an appropriate force as shown by the white arrow in FIG.

  Then, the trunk portion 104 of the container body 101 is elastically deformed from the state shown by the two-dot chain line in FIG. 2 to the state shown by the solid line in FIG. The internal volume of the container main body 101 is reduced by the pressing force due to the elastic deformation of the body portion 104. Therefore, the air 109 located on the bottom 103 side of the container body 101 is supplied to the mixing chamber 30 of the mixing unit 3 through the second check valve 82 and the supply pipe 4 as shown by the solid line arrow in FIG. The liquid content 105 located on the opening 102 side of the container body 101 is supplied to the mixing chamber 30 of the mixing unit 3 through the second supply port 32 of the mixing unit 3 as indicated by the solid line arrow in FIG. . The air 109 and the liquid content 105 supplied to the mixing chamber 30 are mixed in the mixing chamber 30 and foamed into bubbles 108. The foam 108 passes through the foaming member 51 of the discharge path 50 of the discharge unit 5 and is discharged from the discharge path 50 to the outside of the container 100.

  When the squeeze to the container main body 101 is stopped, the container main body 101 elastically returns from the state shown by the solid line in FIG. 2 to the state shown by the two-dot chain line in FIG. Then, the part (air 109 room) where the air 109 in the container 100 is located becomes a negative pressure with respect to the atmosphere. For this reason, the air outside the container 100 is taken into the container 100 through the air intake 6, the air intake pipe 7, and the first check valve 81 as indicated by the solid line arrow in FIG. 2. Thus, if the container main body 101 is continuously squeezed with an appropriate force, the bubbles 108 can be discharged from the discharge portion 5.

  When the liquid content 105 in the container 100 is used up, the dispenser 1 is removed from the opening 102 of the container main body 101, and a new liquid content 105 is put into the container main body 101. By attaching to the opening 102, the dispenser 1 and the container body 101 can be reused. Also, the dispenser 1 can be reused when a new container body 101 containing the liquid contents 105 is used.

  When the container main body 101 is squeezed with an appropriate force in the upright state of the container 100, the liquid content 105 located on the bottom 103 side of the container main body 101 is mixed through the second check valve 82 and the supply pipe 4. The air 109 supplied to the mixing chamber 30 of the unit 3 and located on the opening 102 side of the container body 101 is supplied to the mixing chamber 30 of the mixing unit 3 through the second supply port 32 of the mixing unit 3. The air 109 and the liquid content 105 supplied to the mixing chamber 30 are mixed in the mixing chamber 30 and foamed into bubbles 108. The foam 108 passes through the foaming member 51 of the discharge path 50 of the discharge unit 5 and is discharged from the discharge path 50 to the outside of the container 100.

(Description of the effect of Embodiment 1)
The dispenser 1 and the container 100 according to the first embodiment are configured and operated as described above, and the effects thereof will be described below.

  The dispenser 1 and the container 100 according to the first embodiment can discharge the foam 108 from the discharge unit 5 by squeezing the container main body 101. For this reason, the dispenser 1 and the container 100 according to the first embodiment need to switch the discharge port to the first discharge port or the second discharge port with a cap or a switching cover, like the conventional foam / liquid dispenser of Patent Document 1. Therefore, the desired foam 108 can be reliably discharged from the discharge unit 5 by simply squeezing the container main body 101.

  Further, the dispenser 1 and the container 100 according to the first embodiment can discharge the bubbles 108 from the discharge unit 5 by squeezing the container body 101 in both the inverted state and the upright state of the container 100. it can. For this reason, the dispenser 1 and the container 100 according to the first embodiment, like the conventional squeeze container of Patent Document 2, are erect when the bubbles are ejected, and are inverted when the stored liquid is ejected.

And it can prevent leaking outside the container 100 through the air intake 6.

  That is, when the first check valve 81 is directly attached to the air intake portion 6 without using the air intake pipe 7, the first check valve 81 opens the opening of the container body 101 in the inverted state of the container 100. Since the first check valve 81 is opened when the squeeze force is released from the container main body 101, the first check valve 81 is opened. The liquid content 105 on the 102 side may leak to the outside of the container 100 through the first check valve 81 and the air intake 6 due to gravity. On the other hand, the dispenser 1 and the container 100 according to the first embodiment have the first check valve 81 attached to the air intake portion 6 via the air intake pipe 7, thus preventing leakage of the liquid content 105. be able to.

  In the dispenser 1 and the container 100 according to the first embodiment, a second check valve 82 is attached to the other end of the supply pipe 4. Therefore, when the container main body 101 is squeezed, the second check valve 82 is opened, and the air 109 or the liquid content 105 in the container 100 in the inverted state shown in FIG. 2 or the upright state shown in FIG. It can be supplied to the mixing unit 3 through the check valve 82 and the supply pipe 4. When the container body 101 is not squeezed, the air 109 in the supply pipe 4 is closed by closing the second check valve 82 in either the inverted state shown in FIG. 2 or the upright state shown in FIG. Alternatively, the liquid content 105 can be prevented from entering the container 100. Thereby, in the dispenser 1 and the container 100 of Embodiment 1, the foam 108 can be discharged from the discharge part 5 by squeezing the container main body 101 in the inverted state and the upright state of the container 100.

  Further, in the dispenser 1 and the container 100 according to the first embodiment, since the inner diameter of the second supply port 32 is about 0.7 mm and the inner diameter of the supply pipe 4 is about 4 mm, the inverted state of the container 100 shown in FIG. The squeezing of the container body 101, the air 109 is supplied to the mixing chamber 30 through the supply pipe 4, and the liquid 109 is supplied to the mixing chamber 30 through the second supply port 32. And the liquid content 105 is about 4: 1. For this reason, the dispenser 1 and the container 100 according to the first embodiment can obtain the foam 108 having a good foaming property of the mixture of the air 109 and the liquid content 105 and having good foaming. In the upright state of the container 100 shown in FIG. 1, the foam 108 is slightly inferior to the inverted state of the container 100 shown in FIG. 2, but the bubbles 108 can be discharged from the discharge unit 5. .
