However, since the stem rubber is fixed while being pressed by a covering (cover cap) that fixes the mounting member to the aerosol container, the seal may be incomplete if this pressing is insufficient. Also, any external force may be applied to the container, or the container body may be deformed by being stored in a high temperature environment, so that any part may be displaced, and the seal between the mounting member and the aerosol valve may be May come off.
The present invention provides a discharge container having a separate valve holder for holding a valve housing between the container main body and the discharge container having a highly durable seal structure and excellent manufacturability and safety. The purpose is to do.

The discharge container of the present invention comprises a container body, a valve assembly attached to the opening of the container, and a body seal that seals between the container body and the valve assembly, and the valve assembly is formed in the opening of the container body. A valve holder to be arranged, a valve mechanism attached to the valve holder, a metal cover cap that covers the valve holder and the opening of the container body, and that fixes the valve holder to the opening of the container body; A valve seal that seals between the valve holder and the valve mechanism, the valve seal having a substantially circular cross section, and an inner surface of a holder portion that passes through the top and bottom formed in the valve holder, and the holder portion constitute a seal structure is compressed between the inserted is the outer surface of the housing of the valve mechanism, before Stepped portion provided in the valve mechanism, is characterized in that engaged with the support step portion provided to the holder portion.

Such a discharge container is preferable in which the container body is made of a synthetic resin.
In such a discharge container, the inner surface of the holder part to which the valve seal is compressed and the outer surface of the housing are preferably parallel vertical surfaces arranged at a predetermined interval.
Further, in such a discharge container, the main body seal has a substantially circular cross section, and is compressed between the inner surface of the container main body and the outer surface of the stopper portion of the valve holder inserted into the opening of the container main body. What is sealed is preferable.
In the discharge container of the present invention, it is preferable that a plurality of valve mechanisms are mounted on a plurality of holder portions formed on the valve holder.

The discharge container of the present invention comprises a container body, a valve assembly attached to the opening of the container, and a body seal that seals between the container body and the valve assembly, and the valve assembly is formed in the opening of the container body. A valve holder to be arranged, a valve mechanism attached to the valve holder, a metal cover cap that covers the valve holder and the opening of the container body, and that fixes the valve holder to the opening of the container body; A valve seal that seals between the valve holder and the valve mechanism, the valve seal having a substantially circular cross section, and an inner surface of a holder portion that passes through the top and bottom formed in the valve holder, and the holder portion In order to form a seal structure by being compressed with the outer surface of the housing of the valve mechanism to be inserted, Pressurizing pressure agents filled in the main body can be stored stably for a long period of time without leakage. In addition, since the valve holder and the container body are fixed while the valve holder is covered with a metal cover cap, even if an external force is applied to the container body, such as dropping the discharge container or hitting an object, the housing is particularly against the holder part. Even if the vertical displacement occurs, the horizontal distance between the inner surface of the holder portion and the outer surface of the housing is maintained, and the seal structure of the valve seal is maintained.
Further, when the valve mechanism is inserted into the valve holder, the seal does not become incomplete due to twisting of the valve seal, and the manufacturing is simple and suitable for production.

  When the container body is made of a synthetic resin, the container body is reduced in strength and deformed by the pressure of the propellant when stored in a high temperature environment near the glass transition temperature of the synthetic resin, but the radial direction of the valve holder Expansion and deformation of the metal are prevented by a metal cover cap. As a result, even when the container body is deformed, the horizontal distance between the inner surface of the holder portion and the outer surface of the housing is maintained, and the seal structure of the valve seal is also maintained. That is, even if the container body is deformed, the deformation of the valve holder can be prevented, so that the seal structure of the body seal that seals between the container body and the valve assembly can be opened before the seal structure of the valve seal. Thus, even when there is an abnormality in the container body, the pressurizing agent (including the contents) can be discharged from a certain direction, which is safe for the user.

In such a discharge container, when the inner surface of the holder part to which the valve seal is compressed and the outer surface of the housing are parallel vertical surfaces arranged at a predetermined interval, the housing is attached to the holder part. On the other hand, the valve seal is stable even if it is displaced in the vertical direction.
When the main body seal has a substantially circular cross section and is sealed between the inner surface of the container main body and the outer surface of the stopper portion of the valve holder inserted into the opening of the container main body, the container main body is deformed. Unless otherwise, the seal structure is stable.

  When a plurality of valve mechanisms are mounted on a plurality of holder portions formed on the valve holder, the position where the valve mechanism is mounted is shifted from the central axis of the container body, and the shape is difficult to press each valve mechanism evenly. In spite of this, it becomes a discharge container that discharges a plurality of contents having high sealing performance and high durability of the sealing structure.

Any substantially circular shape can be used. Further, it is made of an elastic material such as nitrile rubber (NBR), butyl rubber (IIR), fluorine rubber, or silicone rubber.

Next, the manufacturing method of the discharge product which fills the discharge container 10 with the contents will be described.
First, the upper part of the connecting member 17 of the pouch is inserted into the lower end of the valve holder 21 to which the aerosol valve 22 is attached, the valve connecting part 17b is connected to the connecting part 31a of the aerosol valve 22, and the protrusion 17d at the upper end is hooked. Engage with the portion 28d.
The valve holder 21 to which the aerosol valve 22 and the pouch 12 are connected is disposed above the container body 11 so that the body seal 14 is above the inner surface 11b of the opening of the container body 11. In this state, a pressurizing agent is filled from between the container body 11 and the valve holder 21 (undercup filling), and at the same time, the valve holder 21 is pushed down and inserted into the container body 11, and the lower end of the cover cap 23 is The fixing portion 23d is formed by caulking. At this time, the main body seal 14 is compressed and sealed between the inner surface 11b of the opening of the container main body and the holding groove 26a of the valve holder 21, and the valve seal 24 includes the rising wall 28b of the holder portion and the holding groove 31c of the housing. And the discharge container is sealed.
The contents are then filled into each pouch from the aerosol valve. However, the contents may be filled before the pouch 12 is inserted into the container body 11 or may be filled before the undercup is filled.

The discharge container 10 of FIG. 1 includes a main body seal 14 that seals between the inner surface 11b of the container main body 11 and the outer peripheral surface of the valve assembly 13, the inner surface of the holder portion 28 of the valve holder 21, and the outer surface of the housing 31 of the aerosol valve 22. Since the valve seal 24 composed of an O-ring that seals the gap is provided, the contents filled in the pouch 12 and the pressure agent filled in the container body can be stably stored for a long period of time.
In addition, when the temperature during storage of the discharge container 10 is increased, the container body 11 (60 to 65 ° C. when PET is used) begins to gradually deform, and further increases to a high temperature (70 to 75 ° C. when PET is used). Then, as shown in FIG. 3, the container body 11 is deformed so that the neck portion expands from the shoulder portion due to the pressure of the pressurizing agent and the strength reduction of the container body. At this time, the flange portion 11a of the container body 11 is held between the fixing portion 23d of the cover cap 23 and the stopper portion 26 of the valve holder 21, so that the valve assembly 13 as a whole does not come off, but the body seal 14 is released. The On the other hand, since the metal valve holder 21 hardly deforms at this time, even if the container body 11 is deformed, the deformation of the valve seal 24 is minimized, and the seal structure by the valve seal 24 is maintained. Thus, even when the strength of the container main body is reduced in a high temperature state or the like and the container main body 11 is deformed, the pressurizing agent can be discharged from a certain direction, which is safe for the user.
Note that the aerosol valve 22 may be slightly displaced in the vertical direction with respect to the valve holder 21 with the deformation of the container body (the pressing and fixing of the aerosol valve 22 by the cover cap 23 may be sweetened). Since the distance between the inner surface of the housing and the outer surface of the housing is maintained, the sealing structure by the valve seal 24 is also maintained. In particular, in the case where two aerosol valves are attached as in the discharge container 10 of FIG. 1, the center of the aerosol valve and the center of the container body are misaligned, so that it is difficult to press evenly and maintain the sealing performance. By using this, a highly durable discharge container with a sealed structure is obtained.

Further, even when an external force is applied to the discharge container 10 by dropping the discharge container 10 or hitting the discharge container 10, the seal structure by the valve seal 24 is maintained, and the seal between the container body 11 and the valve holder 21 ( The seal is never opened before the body seal 14).
Further, since an O-ring is used as the valve seal 24, when the aerosol valve 22 is inserted into the valve holder 21, the seal does not become incomplete due to the valve seal 24 being twisted, and can be easily installed. Suitable for production.
Since the O-ring is used as the main body seal 14, when the valve holder 21 is inserted into the container main body 11 after filling the under cup, the main body seal is not twisted and the seal is not incomplete. ing.
