Description

  The present invention relates to a discharge member for an aerosol container and an aerosol product using the same. Specifically, the present invention relates to an ejection member for an aerosol container filled with a foamable content and an aerosol product using the same.

2. Description of the Related Art Foamable contents used for aerosol products discharged as a lump-like foam are known. Such foamable contents are composed of an aqueous stock solution containing a foaming agent (surfactant) and a liquefied gas, and an oil-in-water solution in which an liquefied gas that is liquid in an aerosol container (under pressure) is dispersed in the aqueous stock solution. When a mold emulsion is formed and discharged to the outside (under atmospheric pressure), the liquefied gas is vaporized to increase the volume and form a foam with the aqueous stock solution as a liquid film.
Aerosol products filled with such foamable contents are used, for example, as hair styling agents, facial cleansers, disinfectants, and the like. Then, for example, it is common to use the foam while spreading it, for example, by applying the foam to the object for the hand.
On the other hand, as a discharge member for an aerosol container for controlling the shape of a foam, a flat discharge member of Patent Document 1 or a discharge member provided with a throttle port of Patent Document 2 is known.
The flat discharge member of Patent Document 1 forms a foam having a flat shape by passing the foamable contents through an elongated passage and discharging the contents as they are. Thereby, a foam can be made to adhere to the target object uniformly widely.
On the other hand, the discharge member provided with the throttle port of Patent Document 2 forms a foam in the expansion chamber in the discharge port once, and then controls the shape of the foam by passing through the throttle port.

It is sectional drawing which shows the reference example of a discharge member. It is a partial side sectional view showing a reference example of an aerosol product.

The aerosol product P1 in FIG. 1 includes an aerosol container A and a discharge member 10 attached to the valve. Reference numeral 15 denotes a shoulder cover connected to the upper part of the aerosol container A. The shoulder cover 15 guides the vertical movement of the discharge member 10 and protects the aerosol container A. In the aerosol product P1, a palm is placed in the opening of the discharge member 10, and the discharge member 10 is pushed down with respect to the aerosol container A. Therefore, the aerosol container A preferably has a low height. For example, the aerosol container A preferably has a height equal to or less than the diameter of the aerosol container. However, the aerosol container A may be operated toward the target surface by bringing the opening of the discharge member 10 into contact with the target surface. In either case, a ring-shaped discharge is formed.
As shown in FIG. 2a, the discharge member 10 includes a base member 11 attached to the aerosol container A, a cup member 12 disposed on the upper part thereof so as to be movable up and down, and a control member provided in the center of the cup member. 13. In addition, a spring 14 is provided between the base material 11 and the cup member 12 to constantly urge the cup member 12 upward. In the discharge member 10, the space S in the side wall 22 of the cup member 12 and between the control members 13 constitutes a foaming portion, the base portion 11 constitutes a passage portion, and the control member 13 constitutes a control portion. The passage portion is provided with a fixed quantity injection mechanism.

  The base material 11 is provided with the circular bottom face 16 and the inner cylinder part 17 extended upwards from the bottom face, as shown in FIG. 2b. The edge of the bottom surface is a flange portion 16 a that protrudes radially outward from the inner cylinder portion 17. At the center of the bottom surface 16, a cylindrical stem engaging portion 18 that protrudes upward from the bottom surface that receives the stem R (see FIG. 1) of the aerosol container A is formed. At the upper end of the stem engaging portion 18, a cylindrical first communication portion 19 having an upper surface 19a curved in an arc shape is formed. The first communication portion 19 is formed with a communication hole 19 b that communicates the inside of the first communication portion 19 (and the stem engagement portion 18) with the inside of the inner cylinder portion 17. The communication hole 19b is arranged so that the communication hole 19b does not close when a lower surface 24a of the second communication part 24 described later comes into contact. In this embodiment, a plurality of communication holes 19b are formed, but the number is not particularly limited.

As shown in FIG. 2c, the cup member 12 includes a planar base 21, a side wall 22 rising upward from an edge of the base 21, an outer cylinder 23 extending downward from the edge of the base, and a base thereof. And a cylindrical second communication portion 24 penetrating the center of 21 in the vertical direction.
The base 21 has a circular shape. The ring shape of the foam is determined by the side wall 22 extending upward from the edge of the base 21. Therefore, the shape of the base 21 is also designed as appropriate based on the outer shape of the desired foam ring.
The side wall 22 is for foaming and accumulating the foam. The side wall 22 has a curved shape protruding outward and has a cup shape. Thus, the foam formed by making it cup shape can be foamed and stored without being compressed.
The outer cylinder part 23 is arranged so as to move up and down along the outer periphery of the inner cylinder part 17, and the space between the inner cylinder part 17 and the outer cylinder part 23 is sealed.
The second communication portion 24 is a curved concave surface so that the lower surface 24 a can come into contact with the upper surface 19 a of the first communication portion 19. As long as the upper surface 19a and the lower surface 24a can be in contact with each other so that the passage in the second communication passage 24 can be sealed, the surface shapes may be appropriately set. The control member 13 is connected to the upper end of the second communication part 24.

  The control member 13 has a discharge hole 26 formed on the side surface, and includes a cylindrical middle cylinder part 27 into which the second communication part 24 is inserted, and a diameter-expanded part 28 provided on the upper part. A plurality of the discharge holes 26 are arranged radially or formed in a ring shape. The diameter-expanded portion 28 increases in diameter toward the upper side. In particular, the diameter is increased while curving so as to protrude outward. The expanded diameter portion 28 is formed by a foamed portion, and controls so that the accumulated foam does not bond at the center.

  In this embodiment, as shown in FIG. 2a, as described above, the space S formed by the side wall 22 of the cup member 12 and the control member 13 is a foamed portion. A passage portion is configured by the stem engagement portion 18, the first communication portion 19, the bottom surface 16 of the base material 11, the quantitative space S <b> 1 between the inner cylinder portion 17 and the base portion 21 of the cup member 12, and the second communication portion 24. The The foaming part and the passage part are communicated with each other by the control part. The quantitative space S1 also functions as a quantitative chamber.

An aerosol container A in which the discharge member 10 is used is filled with a foamable content C composed of an aqueous stock solution and a liquefied gas. In the aerosol container, the aqueous stock solution and the liquefied gas are emulsified, and when discharged, the liquefied gas is vaporized, and the aqueous stock solution foams and becomes a foam. In such a content C, the aqueous stock solution is 40 to 97% by mass, the liquefied gas is 3 to 60% by mass, the aqueous stock solution is 50 to 95% by mass, and the liquefied gas is 5 to 50% by mass. It is preferable. When the amount of the liquefied gas is less than 3% by mass, the formed foam becomes watery and the shape is easily broken. When the amount of the liquefied gas is more than 60% by mass, the lifetime of the formed foam is shortened.
The aqueous stock solution preferably contains a surfactant in order to form a foam. Such surfactants include nonionic surfactants, anionic surfactants,
Cationic surfactants, amphoteric surfactants, silicone surfactants, and the like are preferable, and anionic surfactants are preferable because they can form a high-quality foam, and fatty acid soaps are particularly preferable.

Next, operation | movement of this discharge member 10 is demonstrated using FIG. First, the palm is placed on the opening of the cup member 12 of the discharge member 10, and the discharge member 10 is pressed downward against the aerosol container A (see FIG. 3a). As a result, the spring 14 is compressed, and the cup member 12 moves downward relative to the base material 11. At this time, the lower surface 24a of the second communication portion 24 of the cup member 12 and the upper surface 19a of the first communication portion 19 of the base member 11 come into contact with each other, and the passage portion (between the quantitative space S1 and the second communication portion 24) is formed. Blocked. Moreover, the lower end of the outer cylinder part 23 contacts the flange part 16a. Further, as shown in FIG. 3b, when the discharge member 10 is pressed downward, the cup member 12 and the base material 11 are integrated, and the stem R is pushed down. As a result, the aerosol container A is opened, and the contents C are introduced into the discharge member 10. At this time, since the quantitative space S1 and the second communication portion 24 are blocked, the contents are accumulated in the quantitative space S1.
Next, as shown in FIG. 3c, when the palm is moved away from the discharge member 10, the stem R returns to the original position, and accordingly, the base material 11 and the cup member 12 integrally move upward. At the same time, the cup member 12 moves upward with respect to the base material 11 due to the elastic force of the spring 14, and the discharge member 10 returns to the state before the operation (the state of FIG. 1). Thereby, the contact of the lower surface 24a and the upper surface 19a is also released, and the passage portion communicates again. Therefore, the contents C stored in the quantitative space S <b> 1 are supplied to the foaming part S through the discharge holes 26. In this embodiment, the spring 14 is used, but the cup member 12 is made of a base material because the content space C (liquid component and liquefied gas component) is at a high pressure in the quantitative space S1 without using the spring 14. 11 moves upward. However, the contents C in the quantitative space S1 can be reliably supplied to the foaming part S by using the spring 14. Since the foamed part S communicates with the atmosphere, the content C becomes a ring-shaped foam C1 in the foamed part S. The foam member C1 may be taken out by turning over the discharge member 10 (aerosol container A), or may be left as it is in the foaming part.

In addition, since the discharge hole 26 is provided in the side surface of the middle cylinder part 27 of the control member 13, the discharge member 26 is cyclically | annularly opened toward the side wall 22 of the cup member 12, and the foaming content The object is discharged along the side wall 22 and the foam accumulates along the side wall 22. Therefore, it becomes a ring shape centering on the middle cylinder part 27. Thus, since the middle cylinder part 27 is provided in the center in the side wall 22, even if a foam is accumulated in the side wall 22, the foam C1 accumulated so as to surround the middle cylinder part 27 has a ring shape. leave. In addition, since the control member 13 of the discharge member 10 in FIG. 1 is provided with the enlarged diameter portion 28 at the upper end of the middle cylinder portion 27, the center hole of the ring-shaped foam remains more clearly.
Thus, the surface area can be enlarged by making a foam into a ring shape. For example, when a fragrance is included in the liquid component of the contents C, the scent can be strengthened by a small amount of discharge by increasing the surface area. Moreover, the effect can be strongly exhibited by including an insecticidal component or an insect repellent and a repellent component. And the user can confirm that the effect was completed by foam drying or withering.

  The discharge member 30 in FIG. 4 includes a push button 31 connected to the aerosol container A, a cup member 32 attached to the front (left side in FIG. 4), and a control member 33 attached to the cup member 32. ing. In the discharge member 30, the space S between the side wall 42 of the cup member 32 and the control member 33 constitutes a foaming portion, the push button 31 constitutes a passage portion, and the control member 13 constitutes a control portion. Reference numeral 34 denotes a shoulder cover that guides the vertical movement of the push button 31 and protects the aerosol container A. The discharge member 30 is different from the discharge member 10 of FIG. 1 in that the foamed portion is opened in the lateral direction and does not include the fixed quantity injection mechanism.

  The push button 31 communicates the tubular stem engaging portion 36 that receives the stem R of the aerosol container A formed at the lower end, the tubular nozzle 37 formed at the front, and the stem engaging portion 36 and the nozzle 37.

Since it is configured in this way, the stem R is pushed down and the aerosol container A is opened by pressing the pressing portion (upper surface) 31a of the push button 31 downward. Thereby, the contents C of the aerosol container A are supplied to the foaming part through the passage part.
On the other hand, the discharge hole 46 a of the discharge member 30 is provided on the side surface of the middle cylindrical portion 46 of the control member 33, as in the case of the discharge member 10 of FIG. It opens annularly toward the side wall 42, and the foam has a cylindrical shape extending in the front-rear direction. In particular, since the control member 33 is in the foamed portion S, the cylindrical foam extends forward so as to surround the control member 33. In addition, in the discharge member 30, although the cylindrical shape of a foam may be destroyed by gravity, a beautiful cylindrical shape can be maintained by making the density of a foam small. As long as the discharge member 30 continues to push the push button 31, the foamable content continues to be discharged, so that a long cylindrical foam can be formed. Thus, by making a foam into a cylindrical shape, the surface area of a foam can be enlarged similarly to the discharge member 10 of FIG. 1, and it can use preferably for a fragrance | flavor, an insecticide, an insect repellent, etc. And the user can confirm that the effect was completed by foam drying or withering.
