Place the lid main body on the container main body so that and face each other, and place it on the crimping jig that has the lower surface crimping section of the container flange section and the lower step crimping section for clamping the inner lid, and install it on the upper surface of the lid flange section. The above-mentioned crimping jig is pressed against the crimping plate to give a deformation corresponding to the distance difference and the sandwiching surface shape of the stepped portion to the inner lid, and at the same time, the liquid between the flange portions is melted by high frequency heat fusion under pressure. There is an encapsulation method.

The contents of the present invention will be described below in detail with reference to the drawings. The container is filled with air freshener, but the method of using this air freshener containing container is to open the lid and then leave the entire container as it is, hang it sideways, or upside down to put the air freshener on the inner lid. In this method, the fragrance is not passed through the inner lid, and only the fragrance is diffused through the container opening of the inner lid and the lid body. Therefore, the lid body and the container body are highly sealed, the lid body is easily opened, the inner lid is not damaged when the lid is opened, and the inner lid is closely attached to the container body to withstand the load of the fragrance. Moreover, the inner lid is required to have a property of transmitting only a fragrance.

FIG. 1 is a partial cutaway view of a cross-sectional view of one embodiment of a container in which an air freshener is sealed according to the present invention. In the container body 2 of the container 1, the fragrance L
Is filled. A container side wall 2B is erected on the outer periphery of the container bottom 2A of the container main body 2, and the outer peripheral edge 4A of the inner lid is placed at a desired position of the container bottom 2A below the lid side wall 3B of the lid main body. Step portion 2C for sandwiching the inner lid sandwiched between the edge portion
Are installed around. A container flange portion 2E extending outward is provided around the upper end of the container side wall portion 2B.

It is natural that the container body having such a structure is required to have liquid permeation resistance when the fragrance is liquid and fragrance permeation resistance of the fragrance, but as will be described later, the lid main body. The polyester resin is most preferable because a considerable rigidity is required in order to sandwich the inner lid between the container and the container body. However, it is preferable that the heat adhesion between the container flange portion and the lid flange portion, especially the high frequency heat fusion property is good, so if the resin layer having such characteristics is provided on the inner surface of the container body, The selectivity of the resin of the container body is further expanded.

The lid body 3 has a lid flange portion that engages with the flange portion 2E of the container body 2, and a lid side wall portion 3B and a lid bottom portion 3A.
Is a drop lid that fits inside the container body. The lid bottom portion 3A forms a container opening portion surrounded by the weakening line 3E, the lid side wall portion 3B standing from the outer circumference of the weakening line 3E, and further outside from the upper end. It is composed of a lid flange portion 3C extending toward one side and a lid inner surface layer 3F provided on the surface of these portions on the container body side. The lid inner surface layer 3F is mainly a lid bottom portion 3A and a lid side wall portion 3B.
A weakening line 3E existing between the lid flange portion 3 and
It is laminated on the container flange portion 2E side of C, and contributes to impart openness of the container and thermal adhesion between the container flange portion 2E and high frequency heat fusion property. Here, the line of weakness raises the pull tab 3D integrally attached to the container bottom portion 3A, and when the tip of the container bottom portion 3A causes downward pressing stress, it is damaged at the tip portion and pulls the pull tab. This is because the bottom 3A of the lid can be removed along the line of weakness so that an opening can be formed in the lid, and it must be a membrane that is not easily damaged until it opens, and it is also permeable to the fragrance of the fragrance. It should be as low as possible.

Of the lid body, the material of the lid bottom portion, the lid side wall portion and the lid flange portion is not particularly limited, but the same material as that of the container body is sufficient, and polypropylene resin is preferably used in addition to polyester resin. As a material for the lid inner surface layer, a multilayer laminated film or sheet is provided with fragrance permeation resistance, and at the same time, a sealing means convenient for heat fusion between a container having a large thickness such as the high-frequency heat fusion property and the lid is provided. It is preferable that the aluminum foil is used as an intermediate layer, the container main body side is provided with a polyester resin, particularly an amorphous polyester resin, and the opposite side can be adhered to a polypropylene resin or other material forming the lid bottom portion or lid side wall portion. The one provided is most preferable.

The inner lid 4 is not particularly limited as long as it is a material which is impermeable to the fragrance itself when volatile or sublimated and is permeable to only the fragrance. When the fragrance is a liquid, the affinity must be low, and even if there is a pinhole, it must be a size that does not penetrate at least by the surface tension of the liquid. ) And lid body 3
It is required that the material is an elastic material that can be strongly sandwiched between (particularly the side wall portion 3B) and can withstand the pressing stress by the tip of the lid bottom portion when the pull tab 3D is lifted (for example, the outer periphery of the inner lid. Even if the portion 4A is deformed like 4C, the elastic property remains, so that the sandwiching between the inner lid 4 and the container body 2 is highly airtight and is not broken at the tip of the lid bottom portion).

Materials used for the inner lid include through-holes and elastic properties such as polyolefin foam, polyester fiber, polyolefin fiber, polyacrylonitrile fiber and other non-woven fabrics, kraft paper and filter paper. Highly paper and the like are particularly suitable. However, the present invention is not limited to the above-mentioned materials, as long as the inner lid has the above-mentioned various characteristics.

FIG. 2 is a partially cutaway view of a sectional view of another embodiment of the container according to the present invention. Although the same parts as those in FIG. 1 are denoted by the same reference numerals and the description thereof will be omitted, the feature of this embodiment is that a convex strip 2D is provided on the inner surface of the surface of the step 2C for sandwiching the inner lid of the container side wall 2B. Due to both the step portion 2C and the convex portion 2D, the outer peripheral portion 4A of the inner lid 4 is not only deformed by a simple thickness change as shown in FIG. 1, but also deformed such as a concave portion 4B. When the container 1 filled with the fragrance agent is used while being upside down, the outer peripheral portion 4A of the inner lid 4 engages with the ridge 2D of the step portion 2C for sandwiching the inner lid and slips due to the load of the fragrance agent L. There is no fear of coming off.

FIG. 3 is an embodiment showing a process of a sealing method according to the present invention after a container is filled with a fragrance, and the same parts as those in FIG. Although the description is omitted, the feature of this embodiment is that the inner lid 4 is sandwiched by the step 2C for sandwiching the inner lid and the lower end of the lid side wall 2B.
Also, a crimping jig 5 for pressing the stepped portion 2C for sandwiching the inner lid and the container flange portion 2E to the lower end of the lid side wall portion 2B and the lid flange portion 3C for thermal bonding between the container flange portion and the lid flange portion. Then, it has a container flange lower surface crimping portion 5A and an inner lid sandwiching step lower surface crimping portion 5B, and the lower surface crimping portion 5B is provided with a convex portion 5C.

The crimping jig 5 is moved in the direction of the arrow. Since the crimping plate 6 is located above the lid flange portion, both the flange portions are pressed by the crimping jig 5 and the crimping plate 6, and the crimping plate 6 is pressed. A high-frequency magnetic wave is sent from the side to raise the temperature of a material, such as an aluminum layer in the lid inner surface layer 3F, which is heated by the high-frequency magnetic wave, and the two flange portions are heat-sealed. On the other hand, due to the presence of the convex portion 5C, the inner lid sandwiching step lower surface crimping portion 5B has a convex portion (2D in FIG. 2) formed by cold drawing on the inner lid sandwiching step portion 2C.
(Corresponding to the above), the inner lid clamping step portion 2C is pressed against the lower end of the lid side wall portion 3B. By this operation, the inner lid is deformed by the protrusion 5C (corresponding to 4B in FIG. 2 and 4C in FIG. 1). In this case, from above the weakening line 3E,
Alternatively, it is desirable to support it from above the lid side wall 3B with a jig corresponding to the above-mentioned pressure bonding plate. Further, although the convex portion 2D has been described as being formed by cold drawing, it goes without saying that the convex portion 2D may be formed in advance.

In this case, in order for the inner lid to be effectively held, the distance between the lower surface of the lid flange portion 3C (including the inner lid layer 3F) and the lower surface of the lid bottom portion 3A (including the inner lid layer 3F) and the inner lid. Four
Is not smaller than the distance between the upper surface of the container flange portion 2E and the upper surface of the inner lid holding step portion 2C, and the distance between the lower surface of the container flange portion and the lower surface of the inner lid holding step portion is crimped. It is necessary that the distance is at least 0.1 mm, preferably 0.2 mm larger than the distance between the container flange lower surface crimping portion 5A of the tool 5 and the inner lid sandwiching step lower surface crimping portion 5B lower surface. By establishing such a distance relationship, the pressure applied by the crimping jig 5 is immediately applied to the inner lid through the inner lid pinching step portion 2C of the container side wall 2B, and the inner lid is compressed to at least 0.1 mm. It will be. Further, the inner lid needs to be large enough to be placed on the upper surface of the inner lid sandwiching step 2C of the container side wall 2B, and when it is small, when the container body and the lid body are pressure-bonded,
If the load is applied when the liquid fragrance is used, it may slip off between the container body and the lid body.

FIG. 4 shows a crimping jig 5 manufactured by the method shown in FIG.
In this embodiment, the inner lid is sandwiched between the pressure-bonding plate 6 and the flange portions so that the flange portions are welded. Also in this case, the same parts as those in FIGS.

FIG. 5 shows a hermetically sealed container obtained in the process of the present invention. Since the inner lid is not yet sufficiently devised, when the container is opened with a pull tab, the container is of course upside down to store the liquid. Since it does not withstand the load of the liquid when the fragrance is used, it falls off between the container body 2 and the lid body 3. This state is shown in FIG. In FIGS. 5 and 6, the same parts as those in FIGS. 1 to 4 are designated by the same reference numerals, and a description thereof will be omitted.
