One of the above-mentioned parts extends over the entire length in the vertical direction, and a plurality of vertical grooves are formed along the circumferential direction. It may be.

  In the spray container 1 of the present embodiment in the above-described configuration, referring to FIGS. 1 and 3, the interior of the container body 2 includes a storage chamber 2A for filling and storing the contents, and a storage chamber 2A and a lower portion of the storage chamber 2A. And a gauge chamber 2B having a smaller cross-sectional area than the storage chamber 2A.

The gauge chamber 2B is formed by an annular interior wall (interior body) 4F that hangs down from the top plate portion 4C of the coupling cap 4 along the direction of the axis L1 and is inserted into the exterior body 3. That is, the gauge chamber 2 </ b> B is configured by a gap S formed between the interior wall portion 4 </ b> F and the inner peripheral surface of the exterior body 3. On the other hand, the storage chamber 2 </ b> A is configured by a space inside the interior wall 4 </ b> F in the container body 2.
In addition, although the interior wall part 4F in this embodiment is integrally formed with the connection cap 4, it can also be made into a different body. When the interior wall portion 4F is provided separately from the connection cap 4, for example, by changing the interior wall portion 4F according to the size (height) of the exterior body 3, Easy to handle.

  The gauge chamber 2B is formed on the outer peripheral side of the container body 2 and is formed so that the inside is visible from the outside of the container body 2, and a scale is formed on the exterior body 3 serving as the outer wall surface of the gauge chamber 2B. It is preferable. Examples of the scale forming method include molding and printing. When the scale is provided in this way, it is possible to easily grasp the appropriate internal pressure of the container body 2. In addition, it may replace with a scale and you may provide the area | region classified by color for every height, and can make it easier to grasp | ascertain a liquid level height in this case. In the present embodiment, the entire exterior body 3 is transparent or translucent. However, a part of the exterior body 3 is made transparent or translucent, and the other part is made opaque by a colored resin, a label, printing, or the like ( The inside of the gauge chamber 2B may be visible as a light-shielding state. In this case, it is preferable to provide a transparent or translucent part along the axial direction of the container body 2.

  The operation of the spray container 1 will be described with reference to FIGS. 1, 2, and 4 to 6.

  As shown in FIG. 4, when the movable member 30 is pulled up, the space X and the gap 36 are expanded, so that the space X and the gap 36 become negative pressure, and the second check valve 34 moves downward. Then, the opening 38 is opened, and air flows into the space X and the gap 36 from the opening 38 (see arrow A1 in FIG. 4).

  After that, as shown in FIG. 5, when the movable member 30 is pushed down, the pressure in the space X and the gap 36 increases, so the opening 38 is closed by the second check valve 34 and the first reverse The outer peripheral edge side of the stop valve 24 is curved downward, and the space X and the container body 2 communicate with each other through the passage hole 29. Thereby, air flows in into the container main body 2 (refer arrow A2 in FIG. 5).

  Therefore, in the spray container 1, by repeatedly pushing and pulling the movable member 30 as described above, air can be sequentially introduced into the container body 2 to increase the internal pressure of the container body 2.

  Then, referring to FIG. 1, when the internal pressure of container body 2 rises, liquid level height H1 of gauge chamber 2B rises as indicated by the arrow in the figure. Here, in the spray container 1, since the gauge chamber 2B is visually recognized and the level of the internal pressure of the container main body 2 can be confirmed based on the liquid level height H1, the internal pressure of the container main body 2 is appropriate for injection. It can be easily confirmed whether or not.

  After that, referring to FIG. 6, the movable member 30 together with the cap 37 is removed from the fixed member 5, the nozzle member 20 is exposed, and the nozzle member 20 is pressed to eject the contents. Here, as shown in FIG. 2, when the nozzle member 20 is pressed, the inner peripheral edge of the first check valve 24 is bent downward by the flange 25 as described above, and the upper end edge of the mounting cylinder portion 21 is By separating from the first check valve 24, the through hole 18 communicates with the groove 28 and the passage hole 27, and the stem 17 communicates with the inside of the container body 2.

As a result, the compressed air in the container body 2 is drawn into the through hole 18 from the groove 28 as shown by the arrow α in FIG. 18 is drawn. Then, as shown by an arrow γ in FIG. 2, a mixture of the contents and the compressed air flows through the stem 27 and is jetted from the nozzle hole 19 with a momentum.
And also in this case, since the gauge chamber 2B can be visually confirmed and the level of the internal pressure of the container main body 2 can be confirmed based on the height of the liquid level, the internal pressure of the container main body 2 is appropriate for injection according to the course of use. It can be easily confirmed whether or not there is (sprayability). Moreover, it is possible to prevent the inside of the container body 2 from being excessively pressurized.

As mentioned above, although embodiment of the spray container concerning this invention was described, this invention is not limited to above-described embodiment, In the range which does not deviate from the meaning, it can change suitably.
For example, the interior wall 4F may have a bottomed cylindrical shape having a bottom provided with at least one opening penetrating in the axial direction.
