On the other hand, samples of foamed contents such as foam for skin care and foam for hair care are not distributed. These contents require a foaming agent for foaming, and the foaming agent has a vapor pressure. When filling a normal packaging bag, the packaging bag is deformed by the vapor pressure and the contents leak or There are problems such as rupture and scattering of contents when opened. Therefore, it is not necessarily suitable as a free sample.

Patent Document 1 includes a bag-like container main body and a cylindrical discharge member connected to the container main body, and a closing portion that is opened by an external force and communicates with the outside is provided at the base end portion of the discharge member. An airtight container is disclosed. Since this sealed container is provided with a closed portion at a position away from the tip portion from which the contents are discharged, even if the contents have vapor pressure, the contents of the discharge member are not scattered immediately after opening. The contents can be reliably discharged from the tip.
However, since the bag-shaped container body of Patent Document 1 is formed by thermally welding two sheets into a bag shape, when stored for a long period of time or when an external force is applied, it is easy to leak from the welded portion. Since the discharge member is also welded together with the sheet, it is easy to leak from this portion.

  Further, a small pressure vessel of the present applicant is known as a product filled with contents having vapor pressure (see Patent Document 2). This small pressure vessel is of an aerosol type composed of a pressure resistant container body of 0.5 to 5 cc and a seal portion that can be opened and hermetically closed. The seal portion includes a stem that is movable up and down in the container body, a valve rubber that closes the stem hole and opens the stem hole when the stem is pushed down, a support rib that supports the valve rubber, and a valve It is comprised from the cover which fixes a rubber | gum to a container main body.

  However, since aerosol products are equipped with a valve, it is obliged to provide a cover or the like so that the valve does not malfunction when not in use. In addition, since aerosol products are filled with high vapor pressure contents with a vapor pressure at 35 ° C. of 0.2 to 0.8 MPa, the standards for containers to be filled are stipulated by law. It is uneconomical to use aerosol products as samples for use up.
