Description

  The present invention is an application member connected to an injection stem of an aerosol container, and the contents in the aerosol container are ejected by pressing the application surface against the skin, and the contents are spread on the application surface and spread on the skin. The present invention relates to an aerosol container application member that can be applied.

  In the aerosol container, the contents accommodated in the container are injected by the pressure of the propellant accommodated together with the contents by releasing the valve mechanism. The valve mechanism is opened and closed by the vertical movement of the injection stem. Normally, when the nozzle connected to the injection stem is pushed in, the injection stem moves, the valve mechanism is released, and the contents are injected.

  In this way, aerosol containers are applied to a wide range of products because the contents can be easily sprayed, and there are many aerosol products that are intended to be applied to the skin, such as cosmetics. In aerosol products intended for the purpose, after spraying the contents toward the skin, the work of spreading the contents uniformly on the skin, such as spreading the liquid in fine particles scattered on the skin by hand, etc. It is normal to do.

  However, such an operation of spreading by hand tends to be bothersome for consumers because the spraying operation is simple. Moreover, it is difficult to wipe off easily depending on the contents, and it may be necessary to wash hands with water, and the convenience that is an advantage of the aerosol product may be significantly impaired.

  Therefore, in aerosol products intended to be applied to the skin, the application for aerosol containers can be applied to the skin evenly while spraying the contents and spreading the contents without soiling the hands. Development of members is desired.

  The form of the application member for an aerosol container of the present invention will be described in detail with reference to the drawings.

  FIG. 1 shows the structure of an aerosol container application member (1) attached to an aerosol container. The aerosol container application member (1) of the present invention is connected to the spray stem (3) of the aerosol container (2), and the contents in the aerosol container sprayed from the spray stem in a state where the aerosol container is inverted are applied to the skin. An application member having a substantially circular application surface (4) for application to the surface, an introduction path (5) for introducing the contents disposed on the axis of the injection stem (3), and an application surface A plurality of openings (7) arranged substantially concentrically with the center of the coating surface in the recess (6) provided in (4), and the contents introduced from the introduction path to the openings, respectively. By providing a plurality of supply paths (8) and a plurality of groove-shaped distribution paths (9) for distributing the contents from the recesses provided on the application surface toward the periphery of the application surface, the aerosol container is inverted. In this state, press the application surface against the skin and spray the contents in the aerosol container. In addition, the contents are applied to the skin while spreading on the application surface.

  The application member (1) for an aerosol container has a substantially circular application surface (4). By making the application surface into such a substantially circular shape, directionality is eliminated, and the application surface is slid in all directions on the skin. The contents can be applied uniformly while In addition, if the application surface (4) is a curved surface with a slightly protruding central portion, the stimulation given to the skin can be reduced even when it is moved on the skin, and the usability can be further enhanced.

  The introduction path (5) is disposed on the axis of the injection stem (3). In an aerosol container, the valve mechanism is released when the injection stem is pushed into the valve mechanism, and the contents in the aerosol container are injected from the tip of the injection stem, but the introduction path is arranged on the axis of the injection stem. Thus, the contents can be smoothly introduced into the aerosol container application member (1).

  The application surface (4) is provided with a recess (6), and a plurality of openings (7) arranged substantially concentrically with the center of the application surface in the recess. The application surface is used to spread the contents sprayed from the spray stem on the skin so as to slide on the skin in close contact with or close to the skin. By providing the part (7) on the bottom surface or side surface of the recess (6) provided on the application surface (4), the contents can be applied without blocking the opening even when the application surface contacts the skin. The surface can be supplied stably. Further, by arranging a plurality of openings concentrically with the center of the application surface, the directionality is eliminated and the contents can be easily supplied to the entire application surface.

  The position of the concave portion provided on the application surface is not particularly limited, but is preferably provided in the vicinity of the center of the substantially circular application surface. This is because the contents ejected from the opening provided in the recess are distributed toward the periphery of the application surface by a plurality of groove-shaped distribution paths, and the contents are efficiently supplied to the entire application surface.

  The shape of the recess is not particularly limited, but it is preferable to have a shape having rotational symmetry such as a circular shape or an annular shape as shown in FIG. By adopting such a shape, the directionality can be eliminated, and the contents can be easily supplied to the entire coated surface.

  In the application member (comparative example shown in FIG. 7) in which the opening is not provided in the recess and the distribution path to be arranged toward the periphery of the application surface is not provided, the opening is blocked by the skin. It is difficult to uniformly apply the contents to the skin because the contents cannot be smoothly ejected and the contents do not spread over the entire application surface.

  The contents introduced from the introduction path (5) are supplied to the opening (7) through the supply path (8), and the supply path is preferably connected to the introduction path at an angle. By inclining the supply path, the contents ejected from the opening are easily distributed along the distribution path toward the periphery of the application surface, and the contents can be smoothly supplied to the entire application surface.

  The inner diameter of the supply path should be appropriately designed according to the viscosity of the contents and the amount of contents supplied to the coating surface, but depending on the inner diameter and number of the supply paths (8), a plurality of supply paths (8) are introduced. It may be difficult to connect directly to the path (5). In such a case, the supply path (8) may be connected to the introduction path (5) via the expansion chamber (11) (FIG. 5). The contents introduced through the introduction path (5) are supplied through the expansion chamber (11) to the opening (7) provided on the coating surface by the plurality of supply paths (8). The size of the expansion chamber can be appropriately designed according to the inner diameter and number of supply paths.

  In the embodiment shown in FIG. 5, the upper end of the introduction path (5) is provided with a relatively large volume expansion chamber (11) extending in the horizontal direction, and a plurality of supply paths (8) are vertically connected from the upper end of the expansion chamber. A structure that extends upward and connects to the opening (7) is adopted (FIG. 5B). As a result, the contents taken in from the introduction path can be stably supplied to a large number of openings. When a relatively large expansion chamber is formed in the aerosol container application member (1) in this way, the aerosol container application member is divided into two parts, upper and lower, as shown in FIG. 5 (b). When these molded products are combined, it is possible to easily form expansion chambers of various sizes between the two molded products.

  The application surface (4) is provided with a plurality of groove-shaped distribution paths (9) from the recesses (6) so as to distribute the contents toward the periphery of the application surface. The content sprayed from the opening (7) reaches the entire application surface from the recess through the distribution path, and the content can be uniformly applied by sliding the application surface on the skin. In addition, since the application surface is substantially circular, if a plurality of distribution paths are provided radially from the recess, the contents can be evenly supplied to the periphery of the application surface.

  What is necessary is just to design suitably the number, shape, etc. of a distribution route (9) according to the kind of content to apply | coat, a usage method, etc. FIG.

  2 and 3 show an embodiment in which the distribution path extending radially from the recess (6) toward the periphery of the application surface (4) is a straight groove shape. 2 and 3 differ in the number of openings and distribution paths.

  FIG. 4 shows an embodiment in which the distribution path is wavy so that the contents meander in a zigzag manner. Since the contents flow in a complicated manner in the distribution path by providing a large number of curved portions in the distribution path in this way, it becomes easier to supply the contents to the entire application surface, and the surface area of the application surface increases. It becomes easy to hold the contents on the coated surface.

  Further, as shown in FIG. 5, the distribution path can be formed in a curved line shape having a convex in the same rotation direction with the center of the application surface as the center. By providing a curved portion in the distribution path, centrifugal force is generated in the contents flowing in the distribution path, the contents are smoothly distributed over the entire application surface, and the surface area of the application surface increases, so the contents easily stay on the application surface. And application to the skin becomes easier. Further, by using a radial curved line having a convex in the same rotation direction, there is no sense of incongruity even when pressed against the skin, and an excellent usability can be obtained.

  The distribution path can also be formed by a plurality of curved lines having protrusions in different rotation directions on the radially inner side and the radially outer side of the application surface. FIG. 6 shows an embodiment in which two curved radial distribution paths having different winding directions are arranged on the center side and the outer peripheral side of the application surface with the annular groove (12) interposed therebetween. In this way, by changing the winding direction between the center side and the outer peripheral side of the application surface, the contents can be flowed in a more complicated manner, effectively distributing the contents over the entire application surface and dramatically increasing the surface area. Since it increases, it becomes possible to hold | maintain the content on a coating surface reliably.

  About the application member for aerosol containers of this invention, the number and shape of the distribution path | route provided in an application | coating surface were evaluated.

  In the embodiment having a linear distribution path extending radially from the recess to the peripheral edge as shown in FIG. 2, the contents when the number of distribution paths, the depth and width of the grooves of the distribution paths are changed Table 1 shows the results of the evaluation of the ease of coating.

  From the results in Table 1, it is confirmed that the distribution route is 3 to 20 and each distribution route has a depth of 1 to 2 mm and a width of 2 to 4 mm, so that scattering of contents can be suppressed and it can be uniformly applied to the skin. did it.

  Next, the shape of the distribution path is set to a linear shape as shown in FIG. 2 or a curved line shape as shown in FIG. 5, and the ease of applying the contents when the depth and width of the groove are changed is evaluated. The results are shown in Table 2. Note that six distribution paths were used.

  As shown in Table 2, good results were obtained with both a straight line and a curved line, but in the evaluation with a groove depth of 2.0 mm and a groove width of 4.0 mm, the curved shape was extremely Good results were shown, and it was confirmed that the curved line shape tends to be superior to the linear shape.
