Description

  The present invention relates to a hair spray container that sprays hair spray contained in a container body onto hair.

  For example, instead of using a hair styling agent such as wax alone to set hair, a method that uses a hair styling agent and a hair spray (hair spray agent) as a trend has become a trend. Has been.

Hair spray is mainly composed of a film-forming agent such as acryl resin alkanolamine, and it is blended with higher alcohols, lanolin derivatives, etc. that give appropriate plasticity to the film, or silicone oils that give gloss to hair. The
A hair spray container that contains and uses a hair spray is filled with a high-pressure gas such as LPG as a propellant together with the hair spray. The hair spray container is usually a spray outlet (spray port) so that the hair spray is sprayed in the horizontal direction (parallel) to the bottom surface of the container, in other words, in the direction perpendicular to the axis of the container that is usually formed in a cylindrical shape. The spout is usually formed on the side surface of the push button.
When the push button of the hair spray container is pressed down during use, a fine hair spray is sprayed on the hair.

When a hair styling agent and a hair spray are used in combination, the hair spray is sprayed, for example, from the inside of the hair bundle, in other words, from the skin of the head to the hair bundle, or the hair on the top of the head. Sprayed inside the raised area.
At this time, in the above-described normal hair spray container, it is not always easy to accurately spray the hair spray on a desired part of the hair, and handling becomes complicated because the hair spray container touches the hair. Furthermore, if the hair spray container is tilted sideways or used upside down in order to eliminate such problems as much as possible, the operation posture of the push button becomes unstable, and the spray pattern of the hair spray agent is softened. Further, a phenomenon in which only the propellant is ejected and the hair spray hardly ejects or the hair spray dripping (after-blowing) may occur.

In order to improve the above-mentioned problem, the axial direction of the nozzle hole of the spray nozzle body is provided in the range of 0 degree to less than 90 degrees with respect to the longitudinal direction of the spray container so that the spray direction is above the spray container, and A hair cosmetic (hair cosmetic container) in which an annular pressing member is provided around the spray nozzle body and a hair treatment agent is sprayed from the nozzle by pressing an arbitrary portion of the pressing surface which is the upper surface of the pressing member ) Has been proposed. According to this hair cosmetic, it is said that the hair treatment agent can be easily sprayed from an arbitrary angle and direction (see Patent Document 1).
Japanese Patent Laid-Open No. 9-12434

  However, the hair cosmetic composition (hair cosmetic container) of Patent Document 1 seems not necessarily sufficient for spraying a hair treatment agent (hair spray agent) onto hair in a desired posture simply and reliably.

  This invention is made | formed in view of said subject, and it aims at providing the hair spray container which can spray a hair spray agent on hair easily and reliably with a more desirable attitude | position.

A hair spray container according to the present invention includes a cylindrical container body that contains a hair spray agent, a spray nozzle that sprays the hair spray agent, a spray nozzle that communicates with the jet port, and a stem. , A side of the jet passage opposite to the side communicating with the jet outlet, a lead-out passage portion having a hair spray agent lead-out passage communicating with or blocking the inside of the container body by the vertical movement of the stem, and pressing with a finger A hair spray container comprising a push button for lowering the stem and communicating the inside of the container body and the ejection passage,
The spray nozzle is formed to have a length of 2 to 5 cm, and an angle between the axis of the spray nozzle and the axis of the container body is set to 30 to 60 degrees, and a breakup mechanism is provided in the ejection passage. Prepared,
The push button is configured to operate according to the principle of a lever, and an operation unit that is provided on the upper surface of the push button and that is pressed with a finger is provided in one radial direction of the container body in a plan view. Features.

  Moreover, the hair spray container according to the present invention preferably has a spray nozzle angle varying mechanism that varies an angle between the axis of the spray nozzle and the axis of the container body.

  In addition, the hair spray container according to the present invention preferably has a spray nozzle length varying mechanism that varies the length of the spray nozzle.

In the hair spray container according to the present invention, the spray nozzle for spraying the hair spray agent is provided so that the length is 2 to 5 cm and the included angle with the axis of the container body is 30 to 60 degrees. Since the break-up mechanism is provided in the ejection passage, when the hair spray agent is sprayed inside the hair bundle, the hair spray agent can be sprayed onto the hair simply and reliably in a desired posture. At this time, the hair spray agent and the propellant are separated and the spray state of the hair spray agent becomes poor, and the possibility that the hair spray agent closes the ejection passage and the like is small.
In addition, the hair spray container according to the present invention is configured such that the push button operates on the principle of lever, and the operation unit that is provided on the upper surface of the push button and that is pressed by applying a finger is a part of the container body in plan view. Since it is provided in two radial directions, the force to press the push button is small, and for example, the amount and time of spraying of the hair spray can be finely adjusted. By using, for example, the spray nozzle can be easily positioned without looking at the mirror and confirming the direction and position of the tip of the spray nozzle.

  An embodiment of the present invention (hereinafter referred to as this embodiment) will be described.

  First, the hair spray container according to the present embodiment will be described with reference to FIGS.

FIG. 1 shows a cross section of an outer surface of a container body portion of a hair spray container 10 according to the present embodiment, a spray nozzle, and the like.
The hair spray container 10 includes a container body 12, a lead-out path portion 14, a spray nozzle 16, and a push button 18. The hair spray container 10 is provided with a cap 19 for protecting the spray nozzle 16 and the like during storage.

The container body 12 is made of an appropriate material such as a metal such as aluminum or tinplate coated with an inner surface to ensure corrosion resistance against the hair spray agent, or a resin such as PET, and has a thickness necessary to ensure a predetermined pressure resistance. Formed.
A hair spray agent is accommodated in the hair spray container 10. The accommodation volume of the hair spray container 10 is, for example, about 100 to 300 ml. As described above, the hair spray agent is mainly composed of a film forming agent such as an acrylic resin alkanolamine, and is mixed with a higher alcohol or lanolin derivative that imparts appropriate plasticity to the film, or gives the hair gloss. Add silicone oil. The hair spray container 10 is filled with a high-pressure gas such as LPG as a propellant together with the hair spray agent.

The lead-out path portion 14 is a device that controls the spraying state and the spraying amount of the hair spray agent, and is usually referred to as a valve.
As shown in FIG. 2, the lead-out path portion 14 includes a stem 20, and the side opposite to the side communicating with the jet outlet of the spray passage of the spray nozzle 16, which will be described in detail later, and the inside of the container body 12 are arranged on the stem 20. It has a hair spray agent lead-out path 22 that communicates or blocks by vertical movement. The hair spray agent lead-out path 22 includes a passage 30 of the hair spray agent 28 in the housing 26 and a passage 32 of the hair spray agent 28 formed inside the stem 20. Openings 31a and 31b are formed in the upper part of the passage 30 and the lower part of the passage 32, respectively.
FIG. 2 is a view showing a state when the hair spray container 10 is not used. The stem 20 is urged upward by a spring 24 provided between the housing 26 provided on the container body side and the stem 20. Since the opening 31a and the opening 31b are isolated, the communication between the passage 30 and the passage 32 is blocked.
When the hair spray container 10 is used, the push button 18 is pushed down with a force exceeding the urging force of the spring 24, whereby the stem 20 contacting the push button 18 is urged downward, and the holes 31a and 31b are urged downward. When the positions of the passages coincide with each other, the passage 30 and the passage 32 are communicated, and the hair spray agent 28 flows into the spray nozzle 16 from the passage 32.
In addition, the lead-out path portion 14 in other words, a valve having an appropriate structure other than that shown in the figure can be adopted.

The spray nozzle 16 and the push button 18 will be described with reference to FIGS.
First, the push button 18 will be described with reference to FIGS. FIG. 3 is a view showing a cross section taken along line III-III in FIG.
The push button 18 is formed in a hollow shape, and has a bottom surface 21 formed in the lower portion leaving an opening 23 through which the stem 20 is inserted. A protruding portion 35 and a stopper 36 are provided on the bottom surface 21 so as to protrude inward (upward). The push-down button 18 has a fixed portion 18a that is locked and fixed to the protruding portion 35, and a movable portion 18b. Further, the push button 18 includes a cylindrical portion 18d that is erected in a diagonally upward left direction in FIG.
The fixed portion 18a and the movable portion 18b are separated by the slit 34 formed over substantially the entire circumference, and are connected only by the connection portion 18c. Below the tube portion 18d, the tube 25 is suspended, and the tube 25 is fitted over the upper portion of the stem 20. A plurality of vertically long ribs 37 are provided on the upper inner surface of the cylinder 25, and the lower ends of the ribs 37 abut against the upper surface of the stem 20. The internal space 39 where the rib 37 of the tube 25 is provided communicates with the passage 32 and serves as a passage for the hair spray agent.
When the operating portion 38 provided on the surface of the movable portion 18b is pushed down with a finger attached, the movable portion 18b moves downward with the connecting portion 18c as a fulcrum, whereby the stem 20 that contacts the rib 37 moves downward. The pushed-down movable part 18b comes into contact with the stopper 36 and stops moving.

Next, the spray nozzle 16 will be described with reference to FIGS. 6 is a diagram showing a cross-sectional view taken along the line VI-VI in FIG. 7 of the breakup mechanism.
The cylinder portion 18d is an outer cylinder of the spray nozzle 16. A rod 41 is inserted into the cylindrical portion 18d, and a gap between the cylindrical portion 18d and the rod 41 becomes an ejection passage 42. The ejection passage 42 communicates with the internal space 39. The upper portion of the rod 41 is reduced in a stepped shape, and the lower portion of the rod 41 is integrated with a projecting portion 33 projecting inwardly at the lower portion of the cylindrical portion 18d, whereby the rod 41 is supported. A breakup mechanism 44 is disposed on the upper end surface of the rod 41, and the upper portion of the cylindrical portion 18 d is closed by a nozzle member 43 in which a leg portion 43 a is fitted in the ejection passage 42. The nozzle member 43 has a spout 40 at the center.
The break-up mechanism 44 is a mechanism that acts to form a vortex by turning the hair spray agent at the spout 40.
The break-up mechanism 44 is formed of a flat plate member, and an opening 46 is formed at the center, and projections 48 a to 48 c having a fan shape in a plan view are provided on three sides around the opening 46 on one side. Between each protrusion 48a-48c, the three groove parts 49 which have an outflow port in the position eccentric from the opening 46 are formed. The breakup mechanism 44 is disposed between the rod 41 and the nozzle member 43 with the one surface provided with the protrusions 48 a to 48 c facing the rod 41. The opening 46 communicates with the spout 40.
The spray nozzle 16 is composed of the cylindrical portion 18d and each of the members provided in the cylindrical portion 18d. Needless to say, the spray nozzle 16 may be appropriately configured and provided separately from the push button 18.

The hair spray agent that flows into the ejection passage 42 from the internal space 39 passes through the grooves 49 a to 49 c, turns into a swirling flow, flows into the opening 46, and is ejected from the ejection port 40.
With the breakup mechanism 44, the spray pattern of the hair spray agent can be made into a softly spread mist (fine mist), and the hair spray agent can be prevented from dripping (after blowing). Moreover, there is little possibility that the hair spray agent will block the jet nozzle 40.
Note that the break-up mechanism is not limited to the above, and an appropriate known structure can be used.

The characteristic points of the push button 18 and the spray nozzle 16 described above will be further described.
First, the push button 18 will be described.
The push button 18 can be formed of an appropriate material such as PP resin. The same applies to other members described below.
The push-down button 18 is provided with the connection portion 18c as a fulcrum, the rib 37 as an action point, and provided on the upper surface of the movable portion 18b. The push-down button 18 is pressed with a finger provided in one radial direction of the container body 12 in plan view. The operation is based on the so-called second-type insulator principle with the portion 38 as a power point. For this reason, the force which presses down push button 18 (movable part 18b) may be small. Thereby, for example, the spraying amount and spraying time of the hair spray sprayed onto a predetermined part of the hair can be finely adjusted. It should be noted that the push button 18 can have another appropriate structure as long as it operates on the principle of the above-described second-type lever.
Further, as will be described later, the spray nozzle 16 is fixed in the radial direction on the opposite side of the container main body 12 in a plan view with respect to the operation portion 38 of the push button 18, so that a finger is attached to the operation portion 38. By using the hair spray container 10, for example, the spray nozzle 16 can be easily positioned with respect to a predetermined part of the hair without looking at the mirror and confirming the direction and position of the tip of the spray nozzle 16. can do. It should be noted that the arrangement of the operation unit 38 and the spray nozzle 16 is not limited to a position that is 180 degrees opposite in plan view as shown in the drawing, but can be in an appropriate positional relationship as necessary.
It is more preferable to form innumerable protrusions and protrusions on the operation unit 38 in order to prevent a finger operating the operation unit 38 from slipping.

Next, features of the spray nozzle 16 will be described.
The spray nozzle 16 is formed to have a length L of 2 to 5 cm. The diameter of the spray nozzle 16 is not particularly limited, and can be, for example, about 1 to 2 cm in diameter.
Since the spray nozzle 16 has a length L of 2 to 5 cm, for example, when spraying from the inside of the hair bundle, in other words, between the skin of the head and the hair bundle, at the root (hairline) of the hair bundle, or at the top of the head When spraying the inside of the part where the hair is raised, the hair spray agent 28 can be accurately sprayed on a desired part of the hair. At this time, if the length L of the spray nozzle 16 is less than 2 cm, the operability when spraying the hair spray agent on the inside of the hair bundle may be hindered, while the length L is 5 cm. If it exceeds 1, the operability of the hair spray container at the time of use will be hindered, and it may be bulky when not in use and hinder storage.
Also, the spray nozzle 16 is included angle theta ₁ of the axes of the container body 12 of the spray nozzle 16 is provided so as to 30 to 60 degrees. Thereby, the hair spray agent 28 can be accurately sprayed on a desired part of the hair in a natural posture in which the container body 12 is erected. When the included angle θ ₁ is less than 30 degrees, there is a risk of hindering the spraying of the hair spray agent 28 accurately on a desired portion of the hair. In particular, the hair spray agent 28 is separated from the propellant. There is a risk that the sprayed state will deteriorate. On the other hand, if the included angle θ ₁ exceeds 60 degrees, there is a risk of hindering the spraying of the hair spray agent 28 accurately on a desired part of the hair.

Below, the modification 1 and the modification 2 which are two modifications of the hair spray container 10 which concerns on this Embodiment are demonstrated.
As shown in FIGS. 8 and 9, the hair spray container of Modification 1 has a spray nozzle angle variable mechanism that varies the angle θ ₂ between the axis of the spray nozzle 16 and the axis of the container body 12.

The bellows structure 52 formed by As a result, the spray nozzle 16 can be moved to adjust the included angle θ ₂ to a desired value and can be fixed.
Moreover, in the modified example 1-2 shown in FIG. 9, which is another embodiment of the modified example 1, the spray nozzle angle varying mechanism has a universal joint structure in which the joint between the spray nozzle 16 and the push button 18 is a ball joint type. 54, and the lower portion of the universal joint structure 54 is fitted into the upper end portion of the cylindrical portion 18d. Inside the universal joint structure (ball portion) 54, a passage 56 for communicating the ejection passage 42 and the hair spray agent lead-out passage 22 is formed. As a result, the spray nozzle 16 can be moved to adjust the included angle θ ₂ to a desired value and can be fixed.
Note that the spray nozzle angle variable mechanism may adopt an appropriate structure other than these.
The spray nozzle angle variable mechanism according to the first modification is preferable because the included angle can be adjusted according to the user's preference or according to the part of the hair to which the hair spray agent is sprayed.

As shown in FIGS. 10 and 11, the hair spray container of Modification 2 has a spray nozzle length varying mechanism that varies the length of the spray nozzle.
In Modification 2-1 shown in FIG. 10, which is one embodiment of Modification 2, the spray nozzle length variable mechanism is a cylindrical shape that is detachably fitted to the spray nozzle portion 16a of the push button 18 for use. It consists of an attachment 16b.
Moreover, in the modification 2-2 shown in FIG. 11 which is one embodiment of the modification 2, the spray nozzle length variable mechanism includes the two-stage spray nozzle portions 16c and 16d, and the spray nozzle portion 16d is It is fitted into the spray nozzle portion 16c so as to be extendable and contractible. The length of the spray nozzle 16 can be adjusted by pulling out the spray nozzle portion 16d by an appropriate length from the spray nozzle portion 16c.
Note that the spray nozzle length variable mechanism may adopt an appropriate structure other than these.
The spray nozzle angle varying mechanism of the second modification is preferable because the length of the spray nozzle can be adjusted according to the user's preference or according to the part of the hair to which the hair spray is sprayed.
