On the other hand, the seal film portion 52 is elastically deformable and opens when the inside of the container body 10 becomes negative pressure to allow the introduction of outside air from the outside air introduction hole 26a into the inside of the container body 10.

In the present embodiment, the annular and film-shaped seal film portion 52 is adopted as the valve body of the check valve 50, but the present invention is not limited to this embodiment, and is not limited to this embodiment, for example, according to the cross-sectional shape of the cap body 20. It may be rectangular.

In the present embodiment, the nozzle 30 vertically in the cap body 20 between a closed position for closing the introduction flow path 28 and the outside air introduction hole 26a and an open position for opening the introduction flow path 28 and the outside air introduction hole 26a. It is relatively movable.

More specifically, the nozzle 30 includes a guide cylinder portion 32 hanging from the nozzle cylinder portion 31, a lid cylinder portion 33 and a guide cylinder portion 32 coaxially arranged inside the guide cylinder portion 32 at intervals in the radial direction. The opening / closing cylinder portion 34 is provided so as to be coaxially arranged on the outer side in the radial direction at intervals. The guide cylinder portion 32 is arranged between the cap outer cylinder portion 25 and the cap inner cylinder portion 29, and is provided with respect to at least one of the inner peripheral surface of the cap outer cylinder portion 25 and the inner peripheral surface of the cap inner cylinder portion 29. It is designed to slide. As a result, the nozzle 30 can move relative to the cap body 20 in the vertical direction along the cap outer cylinder portion 25 and the cap inner cylinder portion 29.

The opening / closing cylinder portion 34 is arranged on the outer side in the radial direction of the cap outer cylinder portion 25, and the nozzle 30 closes when the lower end of the opening / closing cylinder portion 34 abuts on the upper surface of the step portion 24 and the downward stroke is restricted.

When the nozzle 30 is in the closed position, as shown in FIG. 2, the outer peripheral surface on the lower end side of the lid cylinder portion 33 fits into the inner peripheral surface of the flow path forming cylinder portion 27, and the introduction flow path 28 becomes the nozzle 30. On the other hand, the opening / closing cylinder portion 34 covers the notch portion 25b provided in the cap outer cylinder portion 25, and the outside air introduction hole 26a is closed to the outside. On the other hand, when the nozzle 30 is in the open position, as shown in FIG. 3, the lid cylinder portion 33 is separated from the flow path forming cylinder portion 27, the introduction flow path 28 is opened with respect to the nozzle 30, and the opening / closing cylinder portion is opened. The 34 is displaced from the notch 25b, a part of the notch 25b is exposed to the outside from the lower side of the opening / closing cylinder 34, and the outside air introduction hole 26a communicates with the outside through the notch 25b.

Next, a method of using the squeeze former container 1 having such a configuration will be described.

As shown in FIG. 1, at the start of use, the content M is filled in the storage space S of the container body 10 of the squeeze former container 1 leaving an upper head space. At this time, the filling amount of the content M into the container body 10 is such that the content M is in the mouth portion 11 when the squeeze former container 1 is in an upright posture in which the nozzle 30 is on the upper side with respect to the container body 10. The amount does not reach the lower end of. In the present embodiment, a large head space is provided so that the content M can be sufficiently agitated and foamed inside the accommodation space S when the container body 10 is shaken up and down, left and right. Further, with this large head space, it is possible to make it difficult for the flow path forming cylinder portion 27 to touch the non-foamed liquid portion of the content M.

When ejecting the content M, the user first vigorously pushes the squeeze former container 1 in the vertical direction and the horizontal direction several times as shown by the thick arrow in FIG. 1 with the nozzle 30 in the closed position. shake. As a result, the content M collides with the inner surface of the container body 10 and entrains air inside to foam, forming a large bubble. At this time, since the introduction flow path 28 is closed with respect to the nozzle 30 by setting the nozzle 30 to the closed position, the content M does not accidentally leak from the nozzle opening 31a of the nozzle 30. Further, since the outside air introduction hole 26a is closed by the check valve 50 and the on-off cylinder portion 34, leakage of the contents M from the outside air introduction hole 26a and intrusion of air from the outside air introduction hole 26a are prevented.

Next, as shown in FIG. 3, the user pulls up the nozzle 30 upward to set the opening position so that the storage space S of the container body 10 communicates with the nozzle opening 31a of the nozzle 30, and then the body portion of the container body 10. Squeeze 12 As a result, the user can eject the fine foam-like content M from the nozzle 30. That is, when the body portion 12 is squeezed, a large foam-like content M generated in the storage space S of the container body 10 (in FIG. 3, only one foam-like content is designated for convenience). ) Is guided to the foam regulating member 40 arranged in the nozzle cylinder portion 31 via the introduction flow path 28 by the positive pressure generated in the accommodation space S, and passes through the foam regulating member 40 to become more. The bubbles are adjusted into fine bubbles. Then, the content M having a fine foam shape formed by the foam adjusting member 40 is ejected to the outside in the form of foam from the nozzle opening 31a provided at the tip of the nozzle cylinder portion 31. At this time, since the check valve 50 is held in the closed state by the positive pressure in the accommodation space S, the content M does not leak to the outside through the outside air introduction hole 26a.

On the other hand, when the squeeze of the body portion 12 is released after the content M is ejected from the nozzle 30, the body portion 12 is restored to its original shape as shown in FIG. 4, resulting in a negative pressure inside the container body 10. Is generated, and due to this negative pressure, the seal film portion 52 of the check valve 50 is separated from the lower surface of the step portion 24, and the check valve 50 is opened. Then, when the check valve 50 is opened, outside air is introduced into the container body 10 through the notch 25b and the outside air introduction hole 26a. At this time, a flow resistance is generated when the foam-like content M passes through the foam-regulating member 40 having a fine pitch in the opposite direction, but a path passing through the notch 25b and the outside air introduction hole 26a. By introducing the outside air into the accommodation space S from the inside, the outside air can be smoothly introduced into the inside of the container body 10 and the body portion 12 can be quickly restored.

As described above, according to the present embodiment, the container body 10 is shaken up and down, left and right to form a large foam-like content M, and the large foam-like content M is arranged in the introduction flow path 28 and the alignment. Since the foam member 40 is passed through the foam member 40 to regulate the foam into fine bubbles and the foam is ejected from the nozzle opening 31a, the content M can be combined with the content M without using a pipe for sending the content M to the nozzle 30. It can be mixed with air and ejected in the form of bubbles. Further, since it is not necessary to attach a pipe to the cap body 20, the filling machine can be used to fill the inside of the container body 10 with the contents M, and then the filling machine can be used to cap the mouth portion 11. Therefore, the number of parts and the assembly man-hours of the squeeze former container 1 can be reduced, and the cost can be reduced.

Further, when the body portion 12 is squeezed to eject the foam-like content M and then the body portion 12 is released from the squeeze, the foam-like content M reverses the fine-pitch foam-regulating member 40. By generating flow resistance by passing through the container body 10, the outside air is preferentially given to the accommodation space S of the container body 10 from the outside air introduction hole 26a provided in a system different from the nozzle 30 rather than through the nozzle opening hole 31a of the nozzle 30. Since it can be taken in, the body portion 12 can be restored to its original shape without pulling the foam-like contents M remaining in the nozzle 30 back to the accommodation space S of the container body 10. Therefore, by squeezing the body portion 12 again, the foam-like content M remaining inside the nozzle 30 is ejected from the nozzle 30 while being pushed out by the foam-like content M sent out from the inside of the container body 10. It is possible to continuously eject the foamy content M.

Further, the nozzle cylinder portion 31 of the nozzle 30 is configured to extend in a direction inclined with respect to the axial direction of the introduction flow path 28, and the foam regulating member 40 is arranged in the nozzle cylinder portion 31, so that the squeeze four is used. By squeezing the body portion 12 while the mer container 1 is in the upright posture, the finely textured foam-like content M can be ejected from the nozzle 30 in a desired direction, and its usability is good.

Further, since the nozzle 30 has an opening / closing structure that can be moved between the open position and the closed position, when the container body 10 is shaken up and down and left and right to form a large foam-like content M, the content M is moved to the outside. Leakage can be reliably prevented. Further, when the container body 10 is shaken up and down, left and right, it is possible to prevent the liquid content M from entering the inside of the nozzle 30 from the cap body 20 and stabilize the foam quality at the time of initial ejection. it can.

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 gist thereof.
