The lower end of the closing member 51 and the smooth surface 15b of the mouth portion 15 are hermetically sealed by surface contact between the inner peripheral surface of the closing member 51 and the smooth surface 15b. In this way, the closing member 51 closes the fluid introduction hole 19.

The discharge plug 31 has a distribution cylinder 32 and a coating body 33 arranged in the distribution cylinder 32.
An upper flange portion 35 forming an annular shape along the circumferential direction and projecting outward in the radial direction is formed in the intermediate portion of the outer peripheral surface of the circulation cylinder 32 in the container axis O direction. The outer diameter of the upper flange portion 35 is equivalent to the outer diameter of the mouth portion 15 of the container body 11. The lower portion 36 of the distribution cylinder 32, which is located below the upper flange portion 35, is fitted in the mouth portion 15 of the container body 11. The lower surface of the upper flange portion 35 is in contact with the lower flange portion 52 of the closing member 51.

In the distribution cylinder 32, the upper portion 37 located above the upper flange portion 35 is gradually reduced in diameter from the lower side to the upper side. The opening formed at the upper end of the upper portion 37 is the discharge hole 37a. The discharge hole 37a is arranged coaxially with the container shaft O. The inner peripheral surface of the discharge hole 37a is a smooth surface having the same inner diameter regardless of the position in the container axis O direction. At the upper end of the upper portion 37, a surface to be sealed (reference numeral omitted) is formed on the inner peripheral surface of the portion connected to the lower side of the discharge hole 37a so that the diameter gradually increases from the upper side to the lower side.

The coating body 33 is provided on the tip portion 39 inserted into the discharge hole 37a, the ridged tubular base portion 40 which is connected to the lower side of the tip portion 39 and has a larger diameter than the tip portion 39, and the lower side of the base portion 40.

The step portion 65 formed at the connecting portion between the small diameter portion 62 and the large diameter portion 63 is in contact with the upper surface of the upper flange portion 35 of the distribution cylinder 32.
The discharge container 1 having no cap 61 may be adopted.

Next, the manufacturing method of the discharge container 1 configured as described above will be described with an emphasis on the step of defining the sealed space S between the heat insulating recess 23 and the inner peripheral surface of the outer container 13.
The container body 11 shown in FIG. 3 is, for example, in a state after extrusion blow molding and before a sealing space S is defined between each heat insulating recess 23 and the inner peripheral surface of the outer container 13. The fluid introduction hole 19 is formed by a known punching process or the like.
A fluid is supplied from the fluid introduction hole 19 between the outer peripheral surface of the inner container 12 and the inner peripheral surface of the outer container 13. This fluid flows downward from the fluid introduction hole 19 while expanding and deforming the outer container 13, and when it first reaches the male screw portion 21, it passes through the corresponding intermittent portion 21bA downward. Then, the fluid that has passed through the corresponding intermittent portion 21bA is supplied into the corresponding heat insulating recess 23A through the upper end opening 23a of the corresponding heat insulating recess 23A.

As shown in FIG. 4, the fluid supplied into the corresponding heat insulating recess 23A also includes the other supporting portion 24B and the inner peripheral surface of the outer container 13 in the other heat insulating recess 23B adjacent to the corresponding heat insulating recess 23A in the circumferential direction. It passes between and flows in. In the illustrated example, the fixing support portion 24A adjacent to the corresponding heat insulating recess 23A in the circumferential direction is fixed to the inner peripheral surface of the outer container 13. Therefore, the fluid supplied into the corresponding heat insulating recess 23A passes between the other supporting portion 24B adjacent to the corresponding heat insulating recess 23A on the other side in the circumferential direction and the inner peripheral surface of the outer container 13, and other It flows into the heat insulating recess 23B.
After the fluid is supplied into each of the heat insulating recesses 23 to define the sealed space S, the closing member 51 is fitted into the outer container 13 to close the fluid introduction hole 19.
Here, after the sealed space S is defined, the outer container 13 is restored and deformed before the closing member 51 is externally fitted to the mouth portion 15 of the outer container 13, so that the fluid in each heat insulating recess 23 becomes a fluid introduction hole. It is possible to suppress the discharge from 19.

In the above discharge container 1, a sealing space S is provided between the outer peripheral surface of the body 16 of the inner container 12 and the inner peripheral surface of the outer container 13, and a heat insulating layer between the outside of the discharge container 1 and the inside of the inner container 12. Functions as.
When using the discharge container 1, for example, the user holds the body portion 16 of the discharge container 1 by hand with the discharge hole 37a facing downward, and presses the coated body 33 against the coated portion. When the tip 39 of the coating body 33 is immersed in the discharge hole 37a against the urging force of the urging member 44, the contents are discharged from the discharge hole 37a and applied to the coated portion. At this time, since the sealed space S serves as a heat insulating layer, it is possible to suppress fluctuations in the temperature inside the inner container 12 due to the body temperature and the outside air temperature transmitted from the outside of the discharge container 1.

As described above, according to the discharge container 1 of the present embodiment, the sealing space S is arranged between the outer peripheral surface of the body portion 16 of the inner container 12 and the inner peripheral surface of the outer container 13. The sealed space S functions as a heat insulating layer between the outside of the discharge container 1 and the inside of the inner container 12. Therefore, for example, it is possible to suppress fluctuations in the temperature inside the inner container 12 due to the body temperature and the outside air temperature transmitted from the outside of the discharge container 1. As a result, for example, when the content is applied to the portion to be coated, it is possible to prevent the content from being unintentionally ejected from the discharge hole 37a or the outer diameter of the body portion 16 of the container body 11 from changing. Can be done.

The positions of the fluid introduction hole 19 and the corresponding heat insulating recess 23A in the circumferential direction are the same as each other. Therefore, the air supplied from the fluid introduction hole 19 between the outer peripheral surface of the inner container 12 and the inner peripheral surface of the outer container 13 is brought to the corresponding heat insulating recess 23A in a short moving distance without diverting in the circumferential direction. be able to.
Of the plurality of support portions 24, the fixed support portion 24A is fixed to the inner peripheral surface of the outer container 13, and the remaining other support portions 24B are in detachable contact with the inner peripheral surface of the outer container 13. When a fluid is supplied from the fluid introduction hole 19 between the outer peripheral surface of the inner container 12 and the inner peripheral surface of the outer container 13, this fluid is not limited to the corresponding heat insulating recess 23A of one of the plurality of heat insulating recesses 23. It also flows into the other heat insulating recess 23B adjacent to the corresponding heat insulating recess 23A in the circumferential direction by passing between the other support portion 24B and the inner peripheral surface of the outer container 13. Therefore, for example, it is not necessary to form a plurality of fluid introduction holes 19 in the outer container 13 and separately supply the fluid from these fluid introduction holes 19 to the plurality of heat insulating recesses 23, and the discharge container 1 can be easily operated. Can be manufactured in.

The corresponding heat insulating recess 23A is open toward the mouth portion 15 side along the container axis O direction. As a result, the fluid flowing from the fluid introduction hole 19 between the outer peripheral surface of the inner container 12 and the inner peripheral surface of the outer container 13 toward the body portion 16 side flows into the corresponding heat insulating recess 23A through the upper end opening 23a. This makes it possible to easily supply the fluid into the corresponding heat insulating recess 23A.
The positions of the fluid introduction hole 19 and the corresponding intermittent portion 21bA of the male screw portion 21 in the circumferential direction are the same as each other. Therefore, when the fluid flowing from the fluid introduction hole 19 toward the body portion 16 side between the outer peripheral surface of the inner container 12 and the inner peripheral surface of the outer container 13 reaches the male thread portion 21, the corresponding intermittent portion 21bA is provided. It becomes possible to pass in the container axis O direction. It is possible to prevent the flow of the fluid from being obstructed by the thread 21a of the male thread portion 21.

The discharge plug 31 includes a coating body 33. Therefore, when the coating body 33 is pressed against the coated portion to immerse the coating body 33 in the discharge hole 37a with the discharge hole 37a facing downward, the contents are discharged from the discharge hole 37a and the coated portion is coated. The contents can be applied to.

In the present embodiment, as in the discharge container 2 shown in FIG. 5, the male screw portion 56 may be formed on the outer peripheral surface of the closing member 51 instead of the mouth portion 15 of the container body 11. In this case, the male screw portion 56 does not have to have an intermittent portion.
As in the discharge container 3 shown in FIG. 6, all of the plurality of support portions 24 may be fixed support portions 24A fixed to the inner peripheral surface of the outer container 13. In the illustrated example, four fixing support portions 24A are formed on the body portion 16 of the inner container 12.
In this case, when the discharge container 3 is manufactured, the fluid does not flow in through the fixing support portion 24A between the heat insulating recesses 23 adjacent to each other in the circumferential direction. Therefore, a plurality of fluid introduction holes 19 are separately formed in the outer container 13 corresponding to the heat insulating recesses 23. As described above, the number of the fixing support portions 24A fixed to the inner peripheral surface of the outer container 13 of the discharge container is not particularly limited.

The positions of the fluid introduction hole 19 and the heat insulating recess 23 in the circumferential direction may be deviated from each other. The positions of the fluid introduction hole 19 and the intermittent portion 21b in the circumferential direction may be deviated. The upper end opening 23a may not be formed in the heat insulating recess 23. Even with these configurations, the temperature fluctuation inside the inner container 12 can be suppressed by forming the heat insulating recess 23 that defines the sealed space S in the discharge container.
It is assumed that the fluid introduction hole 19 is formed in the mouth portion 15 of the outer container 13. However, the portion of the outer container 13 in which the fluid introduction hole 19 is formed is not limited to this, and the fluid introduction hole 19 may be formed in the body portion 16 and the bottom portion 17 of the outer container 13.

The number of intermittent portions 21b formed on the thread 21a of the male thread portion 21 may be one, or the intermittent portion 21b may not be formed on the thread 21a. The container body 11 and the cap 61 may not be connected by screwing, but may be connected by, for example, undercut fitting.
In the embodiment, the fluid is air, but the fluid is not limited to this, and may be a gas such as helium gas or a fluid such as water.
The content may be a solid such as powder, granular or tablet, or a liquid. It is also possible to use a highly volatile liquid as the content.
As the discharge plug 31, a configuration that does not have the coating body 33 may be adopted.

Although one embodiment of the present invention has been described in detail with reference to the drawings, the specific configuration is not limited to this embodiment, and the configuration is changed, combined, or deleted without departing from the gist of the present invention. Etc. are also included.
