Description

  The present invention relates to a discharge member for foamable contents, and further relates to an aerosol product including the discharge member.

  Patent Documents 1 and 2 include a plurality of molding holes and a modeling surface in which the molding holes are opened, and a plurality of modeling pieces that have been molded through the plurality of molding holes are combined on the modeling surface to form a modeled object. A modeling head having a modeling part to be formed is disclosed.

JP 2016-26962 A JP, 2006-10919, A

  However, since these modeling heads are provided with a diffusion chamber for supplying the contents to the molding hole between the mounting portion mounted on the stem of the aerosol valve and the modeling portion, many contents are diffused into the diffusion chamber. There is a problem that it will remain.

  Therefore, the present invention provides a discharge member and an aerosol product for foamable contents that can form a foam having a desired shape and can suppress the remaining of the contents in the discharge member. It is an issue.

  The discharge member for foamable contents according to the present invention includes a main body part mounted on an aerosol valve, a molding part having a molding passage for molding the contents supplied from the main body part into a predetermined shape, and the molding passage. The discharge part which has many fine channel | paths covered from the outer side is provided, The said shaping | molding part and the said discharge part are expanded by the pressure of the content supplied from the main-body part, It is characterized by the above-mentioned.

  It is preferable that the molding part and the discharge part are integrated.

  It is preferable that a diffusion chamber is provided between the main body portion and the molding portion, and the molding portion constitutes a part of the diffusion chamber.

  Moreover, it is preferable that it has a ditch | groove which opposes the said shaping | molding channel | path and becomes a supply path of the contents.

  Moreover, it is preferable that the said discharge part has covered the said shaping | molding part.

  The aerosol product of the present invention comprises any one of the above-described discharge member, an aerosol container equipped with the discharge member, and a foamable content that fills the aerosol container and forms a foam after discharge. It is a feature.

  In the discharge member of the present invention, the molding passage of the molding part is covered with a discharge part having many fine passages, and the molding part and the discharge part expand due to the pressure of the contents supplied from the main body part. The contents supplied from the main body are not expelled from the molding passage to the outside, and the molding part and the discharge part swell due to the pressure of the contents, and the contents are foamed inside and temporarily stored. The foamed contents can be slowly supplied to the molding passage and molded, and the foamed portion can be formed on the upper surface by passing through the discharge portion. When the discharge operation is stopped and the contents in the expanded molded part are discharged, the discharge part and the molded part contract, so that the remaining contents in the discharge member can be suppressed. Furthermore, since the foam on the discharge part is pushed up by the foam pushed out at the time of contraction, a more three-dimensional foam can be formed.

  Further, if the molding part and the discharge part are integrated, only one of the molding part and the discharge part is deformed, and a gap is generated between the molding part and the discharge part, and the molding part is discharged from the molding passage. The content (foam) can be prevented from entering the gap, and the foamed portion having a predetermined shape is formed on the upper surface by passing the discharge portion while maintaining the shape molded in the molding passage. Can do.

  Also, if the molded part having flexibility constitutes a part of the diffusion chamber, the molded part expands at the time of discharge and the volume of the diffusion chamber increases, so that the contents easily foam, and the foamed contents The (foam) can be supplied to the molding passage and can be easily molded. After ejection, the volume of the diffusion chamber decreases with the shrinkage of the molding part, and the contents can be prevented from remaining.In addition, when the foam on the ejection part is taken up by a fingertip, the molding part can be deformed toward the diffusion chamber. As a result, the content remaining in the diffusion chamber can be further suppressed.

  If it has a ditch | groove used as the supply path of a content facing a shaping | molding channel | path, it will become easy to supply a content to a shaping | molding channel. Therefore, it is discharged first from the molding passage near the center, and the discharge from the molding passage on the outer peripheral side is delayed. In addition, a large amount of content is discharged from the molding passage near the center, and the discharge amount from the molding passage on the outer peripheral side. Thus, it is possible to suppress unevenness in time and quantity of discharge, such as reducing the number of bubbles, and a foam having a desired shape can be obtained even when the discharge area is large.

  If the discharge part covers the molding part, the shape of the molding passage cannot be seen from the outside, so it is not possible to know what shape of foam will be discharged until it is discharged. Increase.

  Since the aerosol product of the present invention includes any one of the discharge members described above, it is easy to form a foam having a predetermined shape.

The discharge member 10 of the present invention constitutes an aerosol product by being attached to an aerosol container 20 filled with a foamable content. Moreover, in the aerosol product of this invention, the foam of a desired shape can be obtained by discharging a foamable content from the discharge member 10 by discharge operation.
Hereinafter, the mechanism by which each structural member and the foam of a desired shape are obtained is demonstrated in detail.

  As shown in FIG. 1, the discharge member 10 includes a main body part 11 attached to the aerosol valve 21, a base part 12 attached to the main body part 11, and contents supplied from the main body part 11 to the base part 12. Are formed into a predetermined shape, a discharge part 14 that covers the outer surface of the forming part 13, and a fixing member 15 that fixes the forming part 13 and the discharge part 14 to the base 12.

The main body portion 11 is a portion that serves as a base for attaching the molding portion 13 and the discharge portion 14 to the aerosol container 20, and a cylindrical outer portion that is attached (externally fitted) to the stem 21 a of the aerosol valve 21 at the center lower portion thereof. A fitting portion 11a is provided. A cylindrical skirt 11b is provided on the outer periphery of the outer fitting portion 11a.
The main body 11 is also used as a push button when discharging contents, and is provided with a depression 11c serving as a finger hook on the upper one side (right side in the figure). A cylindrical inner fitting portion 11d for mounting (inner fitting) a connecting tube 12a of the base 12 described later is provided on the opposite side (left side in the drawing) of the recess 11c. The inner fitting portion 11d communicates with the outer fitting portion 11a (internal passage 11e). The outer periphery of the inner fitting portion 11d is recessed toward the inside, and a part of the base portion 12 can be inserted.

The base 12 is a connection tool for attaching the molding part 13 and the discharge part 14 to the main body part 11.
As described above, the cylindrical connecting cylinder 12 a is provided in the center of the base 12. At the upper end of the connecting tube 12a, a flange portion 12b extending in the radially outward direction is provided. The flange 12b has an outer edge curved toward the main body. The outer surface of the flange 12b is smooth within a certain range from the connection tube 12a, but a plurality of annular ridges that are concentric with the connection tube 12a are provided in the vicinity of the outer edge. The innermost bulge portion (first bulge portion) 12c is for attaching the molded portion 13 in a state of being floated from the outer surface of the flange portion 12b, that is, a connecting cylinder having a smaller diameter than the molded portion 13 (supply of contents) Road) This is for forming the diffusion chamber D for diffusing the contents discharged from the opening of the passage 12a over the entire surface of the molding portion 13. The raised portions (second raised portion, third raised portion) 12d and 12e outside the first raised portion 12c are used when the fixing member 15 is fixed to the base portion 12. In addition, although all these protruding parts are made into the continuous annular | circular shape, it does not necessarily need to be continuous and may be a form partly parted.

The molding unit 13 is for molding the contents supplied from the main body into a predetermined shape.
This molded part 13 is made of a synthetic resin sheet formed into a film shape using polyethylene terephthalate, polyethylene, polypropylene, polyamide, polyvinyl chloride, an elastomer, a synthetic resin plate formed into a flat plate shape, silicone rubber, urethane rubber, Rubber plates molded into a flat plate using synthetic rubber, foamed synthetic fabrics such as iron-bonded cloth and paper, polyurethane, polyolefins such as polyethylene and polypropylene, polyvinyl chloride, polyamide, polyacetal, polyester and polystyrene It is made of a material such as a hard sponge that has flexibility and non-liquid permeability or liquid permeability lower than that of the discharge part 14, and is formed so that the molding passage 13 a penetrates the molding part 13 in the vertical direction. As the planar shape of the forming passage 13a, for example, as shown in FIGS. 2a to 2c, a heart shape, a star shape, a deformed face, or an arc-like slit-like hole as shown in FIG. 5b is spiral. However, the present invention is not limited to this, and various shapes such as plum blossoms and letters may be adopted. The forming passage 13a may be formed when the forming portion 13 is formed. However, the forming passage 13a may be formed by cutting a line segment (straight or curved) or a point with a laser or a knife, or with the forming passage 13a. This part may be melted with heat. Furthermore, the cross-sectional shape of the molding part 13 may be laminated together with the molding passage 13a using an ABS resin, a photocurable acrylic resin, or the like, and cured by irradiating with ultraviolet rays.

The discharge part 14 is for weakening the force of the foamed content supplied from the shaping | molding channel | path 13a of the shaping | molding part 13, and strengthening a foam and making shape retention property high.
The discharge part 14 is a sheet or cloth made of a sponge-like soft porous material obtained by foaming a synthetic resin such as polyurethane, polyethylene or polypropylene, and other polyolefins. It is in a state in which a large number of fine passages are provided by communicating with each other or by communicating gaps between the fibers, and has flexibility and liquid permeability (liquid permeability higher than that of the molding portion 13). Further, the surface is rough.

  The discharge part 14 and the molding part 13 are integrated with each other by sticking surfaces facing each other and adhering them with an adhesive, welding, iron, or the like. By being integrated, it expands together due to the pressure of the contents, and it becomes difficult to form a gap between them. Therefore, the content (foam) molded into a desired shape by the molding passage 13a can be directly sent to the discharge unit 14 while passing through the shape, and the discharge unit 14 can be allowed to pass through. A foam having a shape of

  The fixing member 15 is for fixing the shaping | molding part 13 and the discharge part 14 to the base 12 as above-mentioned. The fixing member 15 has a ring shape, and the discharge portion 14 can be exposed to the outside through a central opening 15a. The fixing member 15 is provided with a first recess 15b and a second recess 15c corresponding to the second and third raised portions 12d and 12e of the base portion 12, respectively. Further, a press-fit protrusion 15d that is press-fitted between the second raised portion 12d and the third raised portion 12e is provided between the first recessed portion 15b and the second recessed portion 15c.

The molding part 13 and the discharge part 14 are attached to the base part 12 so that the discharge part 14 is on the outer side, and the outer edges of the molding part 13 and the discharge part 14 are connected to the first raised part 12c and the second raised part 12d. The fixing member 15 is fitted into the base portion 12 after the molding portion 13 and the discharge portion 14 are placed on the first raised portion 12 c of the base portion 12 so as to be positioned between the fixing portion 15 and the base portion 12.
If such attachment is performed, the molding portion 13 and the discharge portion 14 are fixed in a state of being stretched on the first raised portion 12c having an annular shape, and the molding portion 13 and the discharge portion 14 are discharged by the pressure of the contents. The part 14 easily expands at the same time, and it becomes difficult to create a space between them. Further, it is possible to prevent the molded portion 13 from becoming loose and the volume of the diffusion chamber D formed between the inner surface of the molded portion 13 and the outer surface of the flange portion 12b from becoming larger than necessary.

  The aerosol container 20 is obtained by attaching an aerosol valve 21 to a bottomed cylindrical container body, and becomes an aerosol product by filling the inside with a foamable content composed of a stock solution and a liquefied gas.

  Examples of the foamable contents include those composed of a stock solution containing a surfactant and a liquefied gas. The surfactant is used for the purpose of forming a foam by vaporizing the liquefied gas when the foamable content is discharged.

Examples of the surfactant include nonionic surfactants, amphoteric surfactants, silicone surfactants, amino acid surfactants, and the like.

  The solvent contains a surfactant, an active ingredient, and the like, and forms a foam liquid film by foaming with the surfactant and the liquefied gas. Examples of the solvent include aqueous solvents such as water and alcohol, and oily solvents such as ester oils and fats. Examples of water include purified water and ion exchange water, and examples of alcohol include ethanol and isopropanol. Examples of the ester oil include tri (caprylic acid / capric acid) glyceryl, and examples of the fat include olive oil and jojoba oil.

The active ingredient is contained in the foam formed on the discharge part, and is effective by evaporating from the foam, and the foam is applied to the human body such as skin and hair, and the target is effective. And those that are effective when applied to the surface.
Examples of active ingredients include fragrance ingredients such as fragrances, deodorant ingredients, bactericidal ingredients, cleaning ingredients, moisturizing ingredients, insecticidal ingredients, and insect repellent ingredients.

  In the stock solution, higher fatty acids such as myristic acid are used for the purpose of adjusting foam elasticity and improving moldability when passing through the molding passage and shape retention of foam formed on the discharge part. Higher alcohols such as cetanol, water-soluble polymers such as gelatin, hydroxyethyl cellulose, and hydroxypropyl starch phosphate may be added.

The liquefied gas is a liquid having a vapor pressure in the aerosol container, and is included in the contents supplied from the main body part by opening the aerosol valve, and expands the molding part and the discharge part, thereby forming the molding passage and the discharge part. Pass through to form a foam of a predetermined shape.
Examples of the liquefied gas include propane, normal butane, isobutane and mixtures thereof, such as liquefied petroleum gas, dimethyl ether, hydrofluoroolefin, and mixtures thereof.

  In the foamable contents, the stock solution is 60 to 98% by mass, the liquefied gas is 2 to 40% by mass, the stock solution is 70 to 97% by mass, and the liquefied gas is 3 to 30% by mass. preferable. If the liquefied gas is less than 2% by mass, it will be difficult to pass through the discharge part, and if the liquefied gas is greater than 40% by mass, the density of the foam will be reduced and the foam shape will collapse when passing through the discharge part. It becomes easy. In addition, the foam formed on the discharge part is further foamed, and the shape tends to collapse. Adjusting the deformation (expansion) state of the molded part and the discharge part at the time of discharge, adjusting the speed of passing through the molding passage and the discharge part to adjust the height (three-dimensionality) and strength of the foam, etc. For the purpose, a compressed gas such as carbon dioxide, nitrous oxide, or nitrogen may be blended.

  In particular, it is preferable to use a foam that is easily formed in the forming passage of the forming portion and that has a desired foam shape because it is difficult to collapse when passing through the discharge portion and a foam having a desired shape is easily obtained. Examples of the foamable contents that become foamy include those composed of an anionic surfactant, a cationic component, an aqueous stock solution containing a polyhydric alcohol and water, a liquefied gas, and a compressed gas. .

  Examples of the anionic surfactant include alkyl phosphates such as potassium lauryl phosphate and sodium lauryl phosphate, polyoxyethylene alkyl ether phosphates such as sodium POE lauryl ether phosphate, ammonium lauryl sulfate, and potassium lauryl sulfate.

Examples of monosaccharides include erythritol, maltitol, sorbitol, and xylitol, and the content thereof is preferably 1 to 30% by mass, and more preferably 3 to 25% by mass in the aqueous stock solution.

  In order to use the aerosol product configured as described above, the finger hook 11c of the main body 11 is pushed down. Then, the contents discharged from the stem 21a pass through the internal passage 11e of the main body part 11 and the connecting cylinder 12a of the base part 12, and are formed between the inner surface of the molded part 13 and the outer surface of the flange part 12b. To D. The contents sequentially flow into the diffusion chamber D. However, since the flow passage area of the fine passage of the discharge portion 14 is small with respect to the discharge amount and there is also a flow passage resistance, it is discharged to the outside with a momentum. However, most of them stay in the diffusion chamber D temporarily and fill the diffusion chamber D. The remaining contents gradually foam in the diffusion chamber D due to vaporization of the liquefied gas. Therefore, the flexible molding part 13 and the discharge part 14 are deformed so as to protrude outward, and the volume of the diffusion chamber D increases (see FIG. 1b). Then, the contents that have spread throughout the entire diffusion chamber D are supplied to the molding passage 13a and molded, and the foam is formed so as to pass through the discharge portion 14 and ooze out from the surface thereof. Therefore, regardless of the size and shape of the opening of the connecting cylinder 12a that opens into the diffusion chamber D, the foam X that is molded along the shape of the molding passage 13a is discharged. Further, since the discharge force is weakened by the discharge part 14, the discharged foam does not scatter outward, and remains on the surface of the discharge part 14 while maintaining the shape formed in the forming passage 13a. . In particular, since the surface of the discharge unit 14 is rough, the shape can be maintained for a relatively long period of time. In addition, since the molding part and the discharge part are deformed so as to swell, the diffusion chamber D can secure a sufficient capacity for the contents to foam and is sent to the molding part 13 in a foamed state. The foam formed in the discharge passage 14 is easily formed into the shape of the forming passage 13a, and additional foaming is suppressed, and the shape of the foam X is easily maintained. In addition, what was shape | molded by the one shaping | molding channel | path 13a may be formed in the surface of the discharge part 14 with the foam as it is, and what was shape | molded by the some shaping | molding channel | path 13a is compounded (it sticks mutually) It may be formed on the surface of the discharge part.

  The amount of foam to be discharged is preferably changed as appropriate according to the shape of the molding passage 13a. For example, as shown in FIGS. 2a to 2c, when the planar shape itself is already a desired shape, the discharge amount may be small. As shown in FIG. 5b, in the case where a desired shape is obtained only by three-dimensional bubbles, it is preferable to increase the discharge amount in order to increase the height of the bubbles. In the molding unit 62 shown in FIG. 5b, the foam discharged from each molding passage 62a is three-dimensionally formed so as to rise on the molding passage 62a, thereby imitating a double blooming rose. A foam is formed on the discharge member 63.

When the lowering of the main body 11 is stopped, the supply of contents from the aerosol container 20 is also stopped. Then, the pressure in the diffusion chamber D also decreases, and the molding unit 13 and the discharge unit 14 naturally return to their original shapes. Therefore, there is little residue of the contents in the diffusion chamber D. For example, the height of the diffusion chamber D (distance from the outer surface of the flange portion 12b to the inner surface of the molding portion 13) during non-ejection is the width necessary for diffusing the contents throughout the molding passage 13a (for example, 0). If it is set to 5 to 5 mm), the residual content can be greatly reduced. Note that, as described above, the molding unit 13 and the discharge unit 14 are deformed so as to swell at the time of discharge, so that the content can be sufficiently foamed at the time of discharge even if the height of the diffusion chamber D is thus reduced. Capacity will be secured.
Further, if the foam X formed on the surface of the discharge unit 14 is scrubbed with, for example, a finger, the molding unit 13 and the discharge unit 14 are deformed so as to be recessed inward (base 12 side). The remaining amount of contents in the chamber D can be further reduced.
In addition, with the shrinkage (pushing) of the molding part 13 and the discharge part 14, the contents in the diffusion chamber D are pushed out somewhat more, so that the foam on the discharge part 14 is pushed up. A three-dimensional foam can also be formed.

  Next, another discharge member 30 will be described. The discharge member 30 shown in FIG. 3 includes a main body 31 that is attached to the aerosol valve 21, a molding portion 32 that is attached to the main body 31 and forms the contents supplied from the main body 31 into a predetermined shape, The discharge part 33 which covers the outer surface of the part 32, and the fixing member 34 which fixes the shaping | molding part 32 and the discharge part 33 to the main-body part 31 are provided. That is, the base is omitted. Further, the present aerosol product includes a cylindrical shoulder cover 35 that covers the outside of the main body 31 at the upper end of the aerosol container 20.

  The main body 31 includes a cylindrical outer fitting portion 31a for mounting on the stem 21a, a flange portion 31b extending radially outward from the upper end of the outer fitting portion 31a, and a skirt 31c extending downward from the outer peripheral lower end of the flange portion 31b. And. The internal passage 31d in the outer fitting portion 31a is open to the surface of the flange portion 31b. Moreover, unlike the said embodiment, the collar part 31b has a smooth outer surface and does not have a protruding part. The skirt 31 c is provided with a step portion 31 e that restricts excessive entry of the fixing member 34 fitted around the main body portion 31 downward.

  The molding part 32 has a thickness as compared with the above-described embodiment that is in the form of a sheet. As thickness, it is larger than the width | variety of the shaping | molding channel | path 32a formed in slit shape or dot shape, for example, 0.5-3 mm. Further, the molding part 32 has already bulged upward in a state where it is attached to the main body part 31. About the point which has a raw material, flexibility, and liquid permeability, it is the same as that of the said embodiment.

  The discharge portion 33 has a thicker outer peripheral end portion than other portions, in other words, a recess 33a is formed except for the outer peripheral end portion. And the shaping | molding part 32 is engage | inserted by this recessed part 33a. The point which has a raw material, flexibility, and liquid permeability is the same as that of the said embodiment.

  The fixing member 34 includes a disc portion 34a having a large opening at the center to expose the discharge portion 33 to the outside, and a cylindrical portion 34b extending downward from the outer peripheral end portion. The cylindrical portion 34 b is fixed to the main body 31 by fitting the main body 31 to the main body 31.

  By the way, the molding part 32 and the discharge part 33 are already bulged outward in a state of being attached to the main body part 31, and between the outer surface of the flange part 31 b of the main body part 31 and the inner surface of the molding part 32. Is formed with a dome-shaped diffusion chamber D. As a method of expanding the molding part 32 and the discharge part 33, the molding part 32 and the discharge part 33 may be formed in a dome shape in advance, and the outer diameter of the discharge part 33 is set to the cylindrical part 34b of the fixing member 34. The inner diameter of the discharge portion 33 may be reduced, and the outer diameter of the discharge portion 33 may be reduced so as to be bulged by being pushed into the cylindrical portion 34b.

  The discharge member 30 having the above configuration performs the discharge operation by holding the cylindrical portion 34b and pressing it downward. The contents discharged from the stem 21 a by the discharge operation flow into the diffusion chamber D through the internal passage (supply passage) 31 d of the main body 31. And the contents are discharged to the outside with a momentum because the flow area of the fine passage of the discharge part 33 is small with respect to the discharge amount as well as the flow resistance as in the above embodiment. Most of them stay in the diffusion chamber D temporarily and fill the diffusion chamber D. The remaining contents gradually foam in the diffusion chamber D by vaporization of the liquefied gas. Therefore, the molding part 32 and the discharge part 33 are further bulged outward. Then, the contents that have spread throughout the entire diffusion chamber D are supplied to the molding passage 32a and molded, and the foam is formed so as to pass through the discharge portion 33 and ooze out from the surface thereof. At this time, the molding portion 32 is provided with a certain thickness. That is, since the length of the molding passage 32a in the discharge direction is long, the discharge direction of the foam is stable, and the shape of the discharged foam is difficult to collapse. Therefore, even if the shape of the forming passage 32a is constituted by a line segment such as a character, the foam body X having an accuracy that can be clearly recognized can be formed.

  When the supply of the contents from the aerosol container 20 is stopped, the pressure in the diffusion chamber D also decreases, and the molding part 32 and the discharge part 33 return to their original shapes. The discharged foam X is removed from the surface of the discharge unit 33 by, for example, scrubbing with a finger. In this case, if the swelled discharge portion 33 is pushed inward, the content remaining in the diffusion chamber D can be reduced. In particular, in the case of the discharge member 30, since the protruding portion is not provided on the outer surface of the flange portion 31b and is smooth, if the discharge portion 33 is pushed down, the inner surface of the molded portion 32 and the outer portion of the flange portion 31b are removed. The surface can be easily brought into contact with each other, and the residual amount can be reduced.

  Next, another discharge member 40 will be described. The ejection member 40 shown in FIG. 4 has a larger ejection area than the ejection member 30 shown in FIG. Specifically, the diameter of the flange portion 31b, the molding portion 42, and the discharge portion 43 of the main body portion 41 is increased. Further, the shoulder cover 45 covering the main body portion 41 has a large diameter, and covers the shoulder portion of the aerosol container 50 having the same large diameter. The same applies to the material.

  Further, in the discharge members 10 and 30, the shape of the molding passages 13a and 32a in plan view is configured by a combination of a hole having a desired shape and a slit-like hole that traces the desired shape. Then, the molding passage 42a is an aggregate of small dot-like holes (diameter 0.3-2 mm), and a large number of these holes are arranged along a desired shape (for example, alphabets are represented by dots as shown in FIG. 4b). Is made up of. In the case of such a forming passage 42a, the foams are separated from each other immediately after discharge, but when a certain amount is discharged, they stick to each other on the discharge portion 43 and a desired shape is obtained.

  The discharge member 40 also differs from the discharge members 10 and 30 in that a concave groove 41a is provided on the outer surface of the flange portion 31b of the main body portion 41. As shown in FIG. 4c, the concave groove 41a is formed in a strip shape that is long in the left-right direction around the opening of the internal passage (supply path) 31d, and opposes most of the molding passage 42a formed in the left-right direction. doing. When the concave groove 41a is provided in this way, the contents supplied from the internal passage 31d can be easily supplied to the molding passage 42a as shown by the arrows. In other words, the concave groove 41a extends the supply path. Therefore, the discharge from the molding passage 42a in the vicinity of the central portion is discharged first, and the discharge from the molding passage 42a in the outer peripheral side is delayed, and a large amount of contents are discharged from the molding passage 42a in the vicinity of the center, so Therefore, it is possible to suppress unevenness in time and quantity of discharge, such as a decrease in the amount of discharge from. Therefore, even when the discharge area is large (when the molding passages 42a are separated from each other), a foam having a desired shape can be obtained.

  Moreover, since the concave groove 41a is provided along the formation direction of the shaping | molding channel | path 42a, ie, it is provided only in the required part, the increase in the residual amount of a content can be suppressed. The concave groove 41a also functions as the diffusion chamber D. In other words, since the concave groove 41a constitutes a part of the diffusion chamber D, the height of the concave groove 41a (groove depth) is taken into consideration. If the height is determined, the capacity of the portion where the concave groove 41a is not provided can be reduced, and the remaining amount can be suppressed as a whole.

  Other configurations are the same as those of the discharge member 30, and thus the same reference numerals are given and detailed description thereof is omitted.

  Next, another discharge member 60 will be described. The discharge member 60 shown in FIG. 5 is characterized in that the diffusion chamber D is not provided. Specifically, as shown in FIG. 5a, no space is provided between the outer surface of the flange portion 31b and the inner surface of the molding portion 62, and they are in contact with each other.

  In the discharge member 60 having the above-described configuration, the contents supplied from the internal passage 31d are deformed so as to bulge the molding portion 62 and the discharge portion 63 outward by the pressure, thereby forming the molding portion 62 and the collar portion. A space corresponding to the diffusion chamber D is formed between 31b and 31b. Therefore, even if the diffusion chamber D is not provided in advance, a foam having a desired shape can be discharged from the plurality of forming passages 62a provided from the vicinity of the center of the forming portion 62 to the vicinity of the outer edge. In particular, if an iron adhesive cloth having a thickness of 0.3 mm is used as a material for the molding part 62 and a cloth having a thickness of 1 mm is used as a material for the discharge part 63, both are pasted from the molding passage 62 a through the discharge part 63. The shape of the foam that is discharged on the surface is difficult to collapse, and the foam rises cleanly. However, the thickness is not limited to this, and can be appropriately changed within a range of 0.1 to 2 mm for the molding unit 62 and 0.1 to 5 mm for the discharge unit 63, for example. Further, as described above, the molding unit 62 shown in FIG. 5b is for obtaining a foam body that simulates double blooming roses. However, by not providing the diffusion chamber D in advance, the molding unit 62 is close to the center of the molding unit 62. The rising of the bubbles becomes so high that it is possible to obtain a bubble that seems to be more blooming in double blooms.

  In addition, when the shaping | molding part 62 and the discharge part 63 are formed with a fabric, a restoring force (contraction property) is weak and it may be difficult to return to an original shape after discharge. In such a case, it returns to the original shape by pushing the discharge part 63 from above. At this time, since the contents remaining between the flange portion 31b and the molding portion 62 are discharged to the discharge portion 63 side, the foam provided on the discharge portion 63 is lifted, and more three-dimensional bubbles are generated. The body is obtained.

  Since other configurations are the same as those of the discharge member 40, the same reference numerals are given and detailed description thereof is omitted.

  As mentioned above, although typical embodiment of this invention was described, this invention is not limited to the said embodiment, It can be implemented in various changes within the scope of this invention. For example, in the above embodiment, the entire molding unit is covered with the discharge unit, but only the opening of the molding passage may be covered with the discharge unit in the molding unit. However, when the entire molded portion is covered with an opaque discharge portion that does not have translucency, it is not known in advance what shape the discharged bubbles will be, so the pleasure of discharging increases. In the case of transparency or translucency, the shape to be discharged is known in advance, which is convenient when there are a plurality of aerosol products having different shapes of the molding passages.

  Moreover, you may use the discharge part which has the liquid permeability under pressure which does not discharge until it reaches a predetermined pressure. In this case, it becomes easy to form the diffusion chamber D. Moreover, the planar shape of the ditch | groove can be suitably changed according to the shape of a shaping | molding channel | path. Moreover, you may provide a ditch | groove in a shaping | molding part.
