In addition, the applicator 15 can be separated from the pouch 11 with the spout 13.

  The pouch 11 includes a content storage portion 16 for storing the content between the pair of laminate films 11 a and 11 b and a sealing seal portion 11 c formed around the content storage portion 16. The form of the pouch 11 is not particularly limited. For example, a flat bag such as a three-side seal bag or a four-side seal bag, a stick-type bag with a palm joint, a pillow-type packaging bag (back-attached bag), a gusset bag, Examples thereof include a standing pouch having a bottom film folded in half. In the example shown in FIG. 1, the pouch 11 is a four-side sealed bag in which a sealing seal portion 11 c is formed on the entire circumference of the pouch 11.

The contents contained in the pouch 11 are liquid, viscous, paste, gel, cream, sol, powder, granular, and a product having fluidity such as a mixture of two or more of these. Is preferred. Specific examples include, for example, mascara, eyeliner, liquid rouge, lip gloss, nail polish, cosmetics such as lotion, foods such as butter and jam, pharmaceuticals such as cream and ointment, and industrial products such as glue and adhesives. It is done. Also, powders such as powders can be cited as contents.
Since the pouch 11 of this embodiment has a simple structure and can be reduced in size, the pouch 11 is suitable for applications with a small capacity of about several cm ³ to several tens of cm ³ , for example.

The spout 13 has a base portion 13 b sealed by the sealing seal portion 11 c and a cylindrical portion 13 a that protrudes from the base portion 13 b to the opposite side of the content accommodating portion 16. A flow path 13c that communicates with the content accommodating portion 16 is formed inside the cylindrical portion 13a and the base portion 13b.
The base 13b of the spout 13 has a flat shape (for example, a boat shape, a rhombus, an ellipse, etc. are preferred) that expands to the left and right as shown in FIG. 4, and in particular, a boat shape (both sides in contact with the film have an arc shape or the like). The shape having a linear bulge and thin left and right ends) is easy and reliable to seal the inner surfaces of the laminate films 11a and 11b.

The applicator 15 includes a gripping part 15a exposed to the outside of the pouch 11, a fitting part 15b formed so as to be fitted inside the cylindrical part 13a of the spout 13, and a flow in the spout 13 from the fitting part 15b. It has a shaft portion 15c extending to the content accommodating portion 16 through the passage 13c, and a brush portion 15d formed in the shaft portion 15c and accommodated in the content accommodating portion 16 of the pouch 11.

The fitting portion 15b can close the flow path 13c of the cylindrical portion 13a by having a portion that is approximately the same as or thicker than the inner diameter of the cylindrical portion 13a (flow path 13c) of the spout 13.
The fitting portion 15b preferably has a shape corresponding to the cross-sectional shape of the flow path 13c in order to seal the cross section of the flow path 13c over the entire circumference. For example, if the flow path 13c is circular in cross section, a spherical shape or a cylindrical shape is preferable. If the flow path 13c is polygonal in cross section, a prismatic shape having a similar cross section is preferable.

The shape of the brush portion 15d is not limited as long as it can be pulled out through the flow path 13c of the spout 13. The brush portion 15d can be formed by planting flexible brush hair around the shaft portion 15c in the radial direction or the spiral direction, or holding the brush hair in the extending direction from the tip of the shaft portion 15c. .
As an application part used for application | coating of the content in the applicator 15, it is not limited to brush parts 15d, such as a twist brush, a flocking brush, an electrostatic flocking brush, a resin integral molding brush, a comb brush, Various forms such as cotton swabs, sponges, scissors, knives and the like can be employed.

The thin portion 14 that connects the applicator 15 and the spout 13 is formed between the tip of the tube portion 13a and the fitting portion 15b. Thereby, as shown in FIG.1 (b), the fitting part 15b is located in the outer side of the cylinder part 13a, and the front-end | tip of the cylinder part 13a is obstruct | occluded before opening.
Further, after the thin-walled portion 14 is broken, as shown in FIG. 3 (b), the fitting portion 15b can be pushed into the inside of the tubular portion 13a to be fitted, and the pouch 11 can be resealed. Thereby, even when the content is not used up, it becomes easy to save, and the content can be used repeatedly.
When the contents are used, the contents can be taken out by attaching the contents (not shown) to the brush part 15d and pulling out the applicator 15 from the spout 13 as shown in FIG.

  As shown in FIG. 1, when the tip of the gripping part 15 a of the applicator 15 is connected to the cylindrical part 13 a of the spout 13 by a small-diameter connecting part 17, the applicator-accommodating pouch 10 filled with the contents is being transported. During storage, the gripping portion 15a is caught by an exterior material such as an outer box or the gripping portion 15a of another applicator-containing pouch 10, and the gripping portion 15a is inadvertently pulled out, and the thin portion 14 is broken and opened. Can be suppressed.

Although it does not specifically limit as laminate film 11a, 11b which comprises the pouch 11, For example, a laminated body provided with a sealant at least on one side, for example, polyethylene (PE), polypropylene (PP), ethylene-vinyl acetate copolymer ( EVA), a polyolefin resin layer such as a cyclic polyolefin is used as the innermost layer (sealant), and a stretched film such as a biaxially stretched nylon film, a biaxially stretched polyethylene terephthalate film or a biaxially stretched polypropylene film is used as a base material, and ethylene is used as necessary. A laminate film having a vinyl alcohol copolymer, a metal or inorganic compound (for example, ceramic such as silica) vapor-deposited layer, or a metal foil such as an aluminum foil as an intermediate layer can be used.
These films are flexible and foldable, are convenient for transportation and storage when empty, are not bulky after use, and are excellent in volume reduction and disposal.

  The laminate film may include a reinforcing layer for complementing strength characteristics. As the resin constituting the reinforcing layer, polyolefin resins such as polypropylene (PP) and polyethylene (PE), biaxially stretched polyethylene terephthalate (O-PET), biaxially stretched nylon (O-Ny), biaxially stretched polypropylene ( OPP) and the like. The thickness of a reinforcement layer is 5-50 micrometers normally, Preferably it is 10-30 micrometers.

An anchor agent layer or an adhesive layer is preferably interposed inside the sealant layer in order to adhere the sealant layer to a substrate or other film. When the sealant layer is formed by an extrusion laminating method, an anchor agent layer in contact with the inside of the sealant layer is formed. When O-PET is used as the substrate, the anchor agent layer need not be used. In the case where a sealant layer prepared in advance as a single layer film is bonded to a substrate or another film by a dry lamination method, an adhesive layer in contact with the inside of the sealant layer is formed. In the case of using the coextrusion method, an adhesive resin such as acid-modified polyolefin may be used.
As an anchoring agent constituting the anchoring agent layer, an anchoring agent generally used for extrusion laminating methods such as polyurethane, polyether, alkyl titanate (organic titanium compound), etc. can be used. They can be selected together.
As an adhesive which comprises the said adhesive bond layer, the adhesive agent generally used for dry lamination methods, such as a polyurethane type and a polyether type | system | group, can be used, and it can select according to the use of a laminated | multilayer film.

  In order to impart functionality to the pouch 11, at least one of the laminate films 11a and 11b has at least one of a gas barrier layer, a non-adsorbing layer, a deoxidizing layer, a light shielding layer, a printing layer, or a transparent window. Is preferred. Two or more of these configurations may be used in combination as necessary.

The gas barrier layer has a function of imparting gas barrier properties to block gas such as oxygen and water vapor from passing through the laminated film. Examples of such a gas barrier layer include a metal foil, a vapor deposition layer of aluminum or an inorganic oxide, a gas barrier resin layer such as ethylene-vinyl alcohol copolymer (EVOH), or vinylidene chloride. In addition, you may share a barrier layer as a reinforcement layer. These gas barrier layers can be provided on one side of the film constituting the base material or the reinforcing layer, and are generally provided as an intermediate layer between the base material and the sealant layer. In the case of an inorganic oxide vapor deposition layer, it can also be used as the outermost layer outside the substrate (the outermost layer on the opposite side of the sealant layer in the laminated film).
The thickness of the gas barrier layer is usually 5 to 50 μm, preferably 10 to 30 μm, when using a metal foil or a gas barrier resin layer. When using a metal vapor deposition layer or an inorganic oxide vapor deposition layer as a gas barrier layer, it can be made thinner than this.

The non-adsorbing layer can be provided in place of the polyolefin sealant when the content contains a component having high adsorptivity to a polyolefin resin used as a normal sealant, such as a low molecular weight volatile organic compound. . As the non-adsorbing layer having high non-adsorbing property and high sealing property, non-adsorbing layer using polyester-based resin such as isophthalic acid-modified polyethylene terephthalate resin or a composition in which polyester resin, polyethylene and compatibilizer are blended is used. An adsorptive resin film is mentioned.
Further, depending on the type of contents, cyclic polyolefin can be used as the non-adsorbing sealant layer.

  The printing layer can be formed of an ink containing a colorant such as a pigment or a dye. The light shielding layer can be formed of a layer having a light shielding property against visible light, such as metal plating or metal foil. If a transparent window is formed by partially omitting the printing layer and the light shielding layer, the contents can be observed from outside the pouch.

  The oxygen scavenging layer can be formed of, for example, a resin layer or a coating film containing an oxygen scavenger having inorganic or organic oxygen scavenging properties. Examples of the oxygen scavenger include reducing substances such as ferrous salt, ascorbic acid, catechol, iron powder, and oxygen-deficient cerium oxide; polymers having an unpolymerized carbon-carbon unsaturated bond in the molecule (for example, butadiene, isoprene, And dienes such as cidiclopentadiene, and polymers or copolymers of monomers having an acrylic group and an olefin group in one molecule. When an iron-based oxygen scavenger such as iron powder is used, it is preferable that salts such as sodium chloride, calcium chloride, potassium chloride coexist as an auxiliary.

  The spout 13 can be molded, for example, by injection molding using a thermoplastic resin. Examples of the thermoplastic resin include polyolefin resins such as polyethylene (PE), polypropylene (PP), and cyclic polyolefin (COP).

  As shown in FIG. 1B, the applicator-accommodating pouch 10 according to the present embodiment has a pair of laminate films 11a and 11b on both surfaces of a spout 12 with an applicator in which an applicator 15 and a spout 13 are integrated. Is provided and the periphery is sealed. For this reason, also when manufacturing this applicator accommodation pouch 10, it can manufacture easily by inserting the spout 12 with an applicator between a pair of laminate film 11a, 11b, and forming the seal part 11c.

  As the manufacturing apparatus, a bag making machine for manufacturing a pouch with a spout can be used. As an example of the bag making machine, a raw film is fed out, cut in the longitudinal direction, and supplied between a feeding part and a pair of laminated films 11a and 11b that supply a plurality of strip films as a pair of laminated films 11a and 11b. Spout insertion means such as a parts feeder for inserting the spout 12 with tool, spout sealing means for sealing the laminate films 11a, 11b and the spout 12 with applicator, and a pouch seal for sealing the periphery of each pouch. Examples thereof include a bag making machine including means and a cutter for separating and cutting each pouch.

The sealing of the spout with applicator 12 (specifically, the base portion 13b of the spout 13) and the laminate films 11a and 11b may be performed in two or more stages. Further, in order to facilitate the insertion and sealing of the spout, the relevant portions of the laminate films 11a and 11b may be preheated or stretched locally before that.
The filling of the contents may be performed, for example, by leaving an opening serving as a filling port at the bottom of the pouch 11 and sealing the contents container 16 by sealing the opening after filling.

As mentioned above, although this invention has been demonstrated based on suitable embodiment, this invention is not limited to the above-mentioned example, Various modifications are possible in the range which does not deviate from the summary of this invention.
