Description

  The present invention relates to a container such as a fragrance and a deodorant using a volatile chemical.

  Conventional liquid fragrance and deodorant containers using volatile chemicals include a rigid container body that stores chemicals, a core material for sucking up chemicals to the outside, and chemicals sucked up by the core material And a diffusing member for diffusing in the air, and the upper part is generally covered with a cover in consideration of aesthetics.

  The volatile liquid volatilization device described in Patent Document 1 is a typical one, and a container that contains a volatile liquid, a core material that is immersed in the container and held at the container mouth, and a container It is a volatilization apparatus provided with the adjustment body in which the flange which can be attached or detached freely and has a larger area than the opening part of a container, the aroma storage piece provided in the adjustment body, the umbrella body fitted to a flange, etc. is provided. This volatilization device absorbs volatile chemicals such as fragrance and deodorant liquid from the container by capillarity of the core material and impregnates it with a water-absorbing piece that absorbs water in contact with the core material. This is a volatilization device configured to diverge.

  The chemical volatilization container described in Patent Document 2 and the fragrance container described in Patent Document 3 have the same basic configuration as the volatilization apparatus described in Patent Document 1. All of these conventional chemical volatilization containers have a rigid container body, and have a structure that is difficult to refill in terms of design, and must be discarded as waste after use. The reason for using a rigid container as the container body is that it has sufficient gas barrier properties when it has been used to store volatile liquids. This is largely due to the fact that it was limited to containers.

  However, in recent years, with the growing awareness of consumers about global environmental protection, it has become an urgent need to review disposable containers with a large environmental load, and fragrance and deodorant containers are becoming no exception.

  When the volatilization member that volatilizes the liquid includes a water-swellable material, the volatilization efficiency can be increased. Moreover, if it is the same diffusion efficiency, since it becomes possible to make the area of a volatile member small, the magnitude | size of the whole container can be made compact.

It is the perspective view which showed one embodiment of the container for chemical volatilization based on this invention. It is the disassembled perspective view which showed one embodiment of the container for chemical volatilization based on this invention.

The chemical volatilization container according to the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing an embodiment of a chemical volatilization container according to the present invention. FIG. 2 is an exploded perspective view showing one embodiment of the chemical volatilization container according to the present invention.
The drug volatilization container 1 according to the present invention is an external container provided with a soft packaging bag 8 that stores a liquid 10 containing a volatile drug, and a volatilization member 3 that stores the soft packaging bag 8 and volatilizes the liquid. It consists of.

The flexible packaging bag 8 has a suction member 6 that sucks up the stored liquid 10 and permeates the volatilization member 3, a mouth plug 7 that fixes the suction member 6, and a cap 5 that is screwed into the mouth plug 7.
The external container includes a container main body 11 that houses the flexible packaging bag 8 from which the cap 5 has been removed, a fixing member 4 that fixes the stopper 7, and a lid 2 that holds the volatilizing member 3 and volatilizes the drug.

  The flexible packaging bag 8 has a structure in which the periphery is heat-sealed using a laminated body having a heat-sealable thermoplastic resin layer on the inner surface, and the plug 7 is attached. As the thermoplastic resin layer (sealant layer) having heat sealability, a material generally used as a sealant layer of a flexible packaging bag can be used. As the sealant layer, polyolefin resin is generally used. Specifically, low density polyethylene, medium density polyethylene, linear low density polyethylene, ethylene / vinyl acetate copolymer, ethylene / α olefin copolymer , Ethylene-based resins such as ethylene-methacrylic acid resin copolymer, blend resin of polyethylene and polybutene, homopolypropylene, propylene / ethylene random copolymer, propylene / ethylene block copolymer, propylene / α-olefin copolymer Polypropylene resin such as coalescence or polyester resin is used.

  In selecting the sealant layer, an appropriate material is selected according to the material of the plug 7. For example, if the material of the plug is a polyethylene resin, it is desirable to select a polyethylene-based sealant layer. Similarly, if the material of the plug is polypropylene resin, the sealant layer is also preferably polypropylene. In addition, if the material of the plug is PET (polyethylene terephthalate) resin, the sealant layer is also preferably polyester.

  As a structure of the laminated body used for the flexible packaging bag 8, the structure which consists of a base material layer, an intermediate | middle layer, and a sealant layer is common. As a base material layer, a general synthetic resin film, that is, a low density polyethylene (LDPE) resin, a high density polyethylene (HDPE) resin, a linear low density polyethylene (LLDPE) resin, a polypropylene (PP) resin, a polyolefin elastomer Polyolefin resins such as polyethylene terephthalate (PET) resin, polybutylene terephthalate (PBT) resin, polyester resins such as polyethylene naphthalate (PEN) resin, cellulose resins such as cellophane and cellulose triacetate (TAC) resin, poly Methyl methacrylate (PMMA) resin, ethylene-vinyl acetate copolymer resin (EVA), ionomer resin, polybutene resin, polyacrylonitrile resin, polyamide resin, polystyrene (PS) resin, polyvinyl chloride (PVC) resins, polyvinylidene chloride (PVDC) resin, polycarbonate (PC) resin, fluorine resin, other synthetic resin film such as urethane resins, paper, etc. can be used.

  As the intermediate layer, in addition to the synthetic resin film and paper similar to those used for the base material layer, an aluminum foil, a gas barrier film on which an inorganic substance is deposited, and the like can be used. As a gas barrier film, when a metal film such as aluminum oxide or silicon oxide is deposited on a PET film or the like, a transparent packaging bag is obtained, so that the contents gradually decrease as in the application of the present invention. It is suitable for those that use it in various ways. The intermediate layer may be a plurality of layers as necessary.

  The shape of the flexible packaging bag 8 is not particularly limited. In addition to the simplest pillow shape in which the sealant layers are opposed to each other for the front material and the back material and the periphery is sealed, bent portions are formed on both sides. Arbitrary gusset bags and standing pouch shapes using bottom tape at the bottom are optional. Since the flexible packaging bag used in the present invention is housed in an external container, self-supporting property is not essential, but it is preferable that it is self-supporting at the point of sale at the store. In the example of FIG. 2, it has a standing pouch shape having self-supporting properties.

  The plug 7 can be efficiently created by injection molding using polyethylene resin, polypropylene resin, PET resin or the like. A male screw is formed on the plug 7 so that the cap 5 is screwed onto the outer peripheral surface. In addition, a seal portion for heat-sealing with the laminated body of the flexible packaging bag is necessary. A suction member 6 to be described later is inserted into the hole at the center of the plug.

  A protective member 9 that covers and protects the suction member 6 from the outside can be integrally formed on the spout 7. The protection member 9 may be a simple straw-shaped tube, or may have a shape obtained by dividing the tube into a plurality of pieces as shown in FIG.

  The cap 5 may be made of the same material as the plug 7, but a seal film using an aluminum foil or the like may be inserted on the surface of the cap 5 where the plug 7 hits in order to enhance the storage stability.

  As the sucking member 6, synthetic fibers such as pulp, cellulose, silk, hemp, wool, cotton, etc., polyethylene fibers, polypropylene fibers, acetate fibers, nylon fibers, acrylic fibers, rayon, polyester fibers, polyvinyl chloride fibers, etc. Resin fibers, glass fibers, carbon fibers and other inorganic fibers are used alone or in combination, and the fibers are bundled into a rod shape, nonwoven fabric or felt shape, or further laminated Used.

  The sucking member 6 is processed into a cross-sectional shape that matches the shape of the opening of the spout 7 using these materials, and has a length that reaches the bottom of the flexible packaging bag. The cross-sectional shape is arbitrary, such as a circular shape, a square shape, or a polygonal shape. When the sucking member 6 is easily broken, it is desirable to protect the surroundings by the protective member 9.

  The container body 11 is a synthetic resin container having a size and a volume capable of accommodating the flexible packaging bag 8. Preferably it has transparency. It can be molded by a general molding method using a plastic material such as PET, PP, PE, and polystyrene. A protrusion or the like for fitting the fixing member 4 is provided on the upper part.

  The fixing member 4 is a donut-shaped member having a stopper fixing hole 12 for fixing the stopper 7 of the flexible packaging bag 8 at the center. The spigot fixing hole 12 may be a long hole or a notch reaching the circumferential portion so that the spigot 7 can be easily hooked and fixed, or a female screw similar to that of the cap 5 is provided. The stopper 7 may be screwed. The material of the fixing member 4 is the same as that of the container body 11, but does not need to be transparent.

  The lid | cover 2 is a member provided with the hole which hold | maintains the volatilization member 3 inside and the liquid which soaked in the volatilization member 3 is easy to volatilize. The shape of the hole is not limited to the slit shape as shown in FIGS. 1 and 2, but may be any shape such as a mesh shape or a honeycomb shape. The material of the lid 2 is the same as that of the container body 11, but it is not necessary to be transparent.

  The volatilization member 3 is a member for efficiently volatilizing the liquid 10 containing the medicine sucked up by the sucking member 6, and is held inside the lid 2. As the material of the volatilization member 3, the same material as that used for the sucking member 6 can be used. However, since the shape is planar, a material that can be easily formed into a sheet is suitable. Examples thereof include cloth, non-woven fabric, felt, and filter paper using various fibers. Volatilization efficiency can be improved by making the volatilization member 3 contain a water absorption swelling material. Moreover, if it is the same volatilization efficiency, an area can be made smaller. As the water-absorbing swellable material, known high water-absorbing resins such as sodium polyacrylate and isobutylene-maleic anhydride copolymer can be suitably used. It is possible to preferably use those superabsorbent resins obtained by embedding and supporting about 50% of the total weight of the above fiber material.

  A PET film having a thickness of 12 μm was used as the base layer, a nylon film having a thickness of 15 μm was used as the intermediate layer, and an LLDPE film having a thickness of 100 μm was used as the sealant layer. Three layers were bonded together using a urethane adhesive to create a laminated film. The laminated film was used as a front and back film and a bottom tape, the sealant layers were opposed to each other, and the peripheral edge portion was sealed except for the opening at the upper end to form a standing pouch.

An LDPE plug for pouring the contents was inserted into the opening at the upper end of the standing pouch, and the plug was fixed to the opening by thermal bonding, and at the same time, the opening was sealed by thermal bonding. Fragrance, ethanol, surfactant, and fragrance made mainly from purified water were encapsulated as the content liquid. In addition, the sucking-up member accommodated in the protective member under the spigot was made of felt.
A standing pouch containing a fragrance was housed in a transparent PP container body, and a PP fixing member containing a diffusion member made of pulp nonwoven fabric and a lid were set to obtain a product.

  This fragrance can be used with a simple operation by simply removing the cap of the standing pouch, setting it on the fixing member, and placing it in the container body. Further, when the content liquid is exhausted, it is only necessary to replace the standing pouch, and the container body can be used repeatedly, so that the burden on the environment can be reduced.
