Description

Content spraying devices, pump-type products and aerosol-type products

[0001] The present invention relates to a content ejection device for ejecting the contents of a pump-type product or an aerosol-type product, a pump-type product, and an aerosol-type product.

[0002] A conventional content spraying device is known that has an elliptical nozzle that sprays the contents of a pump-type product or aerosol-type product in an elliptical shape when observed from the front (see, for example, Patent Documents 1 to 3).

[0003] JP 2011-139994 A JP 2011-177677 A International Publication No. 2016 / 140142

[0004] However, the content spraying devices described in Patent Documents 1 to 3 have a problem in that the shapes of the content spray ranges are almost the same.

[0005] Therefore, an object of the present invention is to provide a content spraying device, a pump-type product, and an aerosol-type product that can realize a novel shape for the shape of the spray range of the content.

[0006] The contents spraying device of the present invention is characterized by having a first nozzle that, when observed from the front, has a spray range for the contents of a pump-type product or aerosol-type product that is longer in a specific direction than in all directions other than the specific direction, and a second nozzle that, when observed from the front, sprays the contents in a direction between the specific direction and a direction perpendicular to the specific direction.

[0007] With this configuration, the content spraying device of the present invention is equipped with a first nozzle whose spray range for the contents of a pump-type product or aerosol-type product is longer in a specific direction than in all other directions when observed from the front, and a second nozzle which sprays the contents in a direction between the specific direction and a direction perpendicular to the specific direction when observed from the front, so that a novel shape can be realized as the shape of the spray range for the contents by the first nozzle and the second nozzle.

[0008] The contents injection device of the present invention may be provided with at least one of the second nozzle that injects the contents toward the upper left and the second nozzle that injects the contents toward the upper right when the specific direction is the up-down direction when observed from the front.

[0009] With this configuration, when the content sprayer of the present invention is configured such that, when the specific direction is up or down when observed from the front, and the second nozzle is configured to spray the content toward the upper left, when a user holds a pump-type or aerosol product in their left hand and operates the content sprayer with their left hand to spray the content toward the front, the spray range of the content from the second nozzle is located in front of or near the position in front of the user's eyes, thereby visually emphasizing the spray of the content to the user. Similarly, when the specific direction is up or down when observed from the front, and the content sprayer of the present invention is configured such that, when a user holds a pump-type or aerosol product in their right hand and operates the content sprayer with their right hand to spray the content toward the front, the spray range of the content from the second nozzle is located in front of or near the position in front of the user's eyes, thereby visually emphasizing the spray of the content to the user.

[0010] The contents injection device of the present invention may be provided with a second nozzle that injects the contents toward the upper left when the specific direction is the up-down direction when observed from the front, and a second nozzle that injects the contents toward the upper right.

[0011] With this configuration, the content spraying device of the present invention has a content spray range from the second nozzle that is located in front of or close to the user's eyes, whether the user is holding a pump product or aerosol product in his or her left hand and operating the content spraying device with his or her left hand to spray the content directly ahead, or whether the user is holding a pump product or aerosol product in his or her right hand and operating the content spraying device with his or her right hand to spray the content directly ahead. Therefore, whether the user is holding a pump product or aerosol product in his or her left hand and operating the content spraying device with his or her left hand to spray the content directly ahead, or whether the user is holding a pump product or aerosol product in his or her right hand and operating the content spraying device with his or her right hand to spray the content directly ahead, the spraying of the content can be visually emphasized to the user.

[0012] The contents injection device of the present invention may be provided with the second nozzle that injects the contents in an upper left direction, the second nozzle that injects the contents in an upper right direction, the second nozzle that injects the contents in a lower left direction, and the second nozzle that injects the contents in a lower right direction when observed from the front and the specific direction is an up-down direction.

[0013] With this configuration, the contents spraying device of the present invention can spray the contents over a wide range while realizing a novel shape for the shape of the spray range of the contents.

[0014] In the content injection device of the present invention, when the specific direction is the up-down direction when observed from the front, the second nozzle that sprays the content toward the upper left, the second nozzle that sprays the content toward the upper right, the second nozzle that sprays the content toward the lower left, and the second nozzle that sprays the content toward the lower right may be arranged at equal intervals on the circumference of the same circle.

[0015] With this configuration, the contents spraying device of the present invention can spray the contents evenly over a wide area while realizing a novel shape for the shape of the spray range of the contents.

[0016] In the contents spraying device of the present invention, the first nozzle may be an elliptical nozzle in which the shape of the spray range of the contents is elliptical when observed from the front.

[0017] With this configuration, the contents ejection device of the present invention can make the shape of the range in which the contents are ejected by the first nozzle a well-balanced shape.

[0018] The pump-type product of the present invention is characterized by comprising the above-mentioned content ejection device and the content.

[0019] With this configuration, the pump-type product of the present invention can realize a novel shape for the shape of the spray range of the contents.

[0020] The aerosol product of the present invention is characterized by comprising the above-mentioned content spraying device and the content.

[0021] This configuration allows the aerosol product of the present invention to realize a novel shape for the spray range of the contents.

[0022] The content spraying device, pump-type product and aerosol-type product of the present invention can realize a novel shape as the shape of the spray range of the content.

[0024] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0025] First, the configuration of an aerosol product according to one embodiment of the present invention will be described.

[0026] Figure 1(a) is a plan view of a portion of an aerosol product 10 according to the present embodiment, and Figure 1(b) is a side cross-sectional view of a portion of the aerosol product 10.

[0027] As shown in Figure 1, the aerosol product 10 comprises a container (not shown) containing contents to be released to the outside, a valve (not shown) attached to the container and releasing the contents inside the container to the outside of the container when a part of the valve is pressed, and a button-equipped cap 20 as a contents spraying device attached to the stem of the valve to press a part of the valve and spraying the contents released to the outside of the container by the valve.

[0028] The button cap 20 includes a cap body 30 that is attached to the container, and a nozzle tip 70 that is attached to the cap body 30 to spray the contents.

[0029] Fig. 2(a) is a front view of a portion of the cap body 30. Fig. 2(b) is a side cross-sectional view of a portion of the cap body 30.

[0030] As shown in Figures 1 and 2, the cap body 30 comprises a container attachment portion 40 that is attached to the container, a button portion 50 that is pressed by the user, and a flexible support portion 60 that is flexible and supports the button portion 50 side so that it can move relative to the container attachment portion 40 side.

[0031] The button part 50 comprises a stem attachment part 51 that is attached to the stem of the valve, a tip attachment part 52 that has a circular hole (hereinafter referred to as the "tip insertion hole") 52a formed therein into which the nozzle tip 70 is inserted, and to which the nozzle tip 70 is attached by inserting the nozzle tip 70 into the tip insertion hole 52a, and an annular protrusion part 53 that is disposed inside the tip insertion hole 52a of the tip attachment part 52. The tip insertion hole 52a has two grooves (hereinafter referred to as "removal prevention grooves") 52b formed therein into which parts of the nozzle tip 70 fit to prevent the nozzle tip 70 from coming off the tip insertion hole 52a.

[0032] The button portion 50 is formed with a flow path 50a through which the contents released from the stem attached to the stem attachment portion 51 flow, two openings 50b for connecting the flow path 50a to the space on the inner periphery of the tip attachment portion 52 and the outer periphery of the protrusion portion 53, and an opening 50c for connecting the flow path 50a to the space on the inner periphery of the protrusion portion 53.

[0033] Fig. 3(a) is a front view of the nozzle tip 70. Fig. 3(b) is a rear view of the nozzle tip 70. Fig. 4(a) is a cross-sectional view taken along the line A-A in Fig. 3(a). Fig. 4(b) is a cross-sectional view taken along the line B-B in Fig. 3(a). Fig. 5 is a cross-sectional view taken along the line C-C in Fig. 3(a).

[0034] 1, 3, 4, and 5, the nozzle tip 70 includes an annular body mounting portion 71 attached to the tip mounting portion 52 of the cap body 30 on its outer circumferential surface side, and an annular central protrusion 72 disposed on the inner circumferential side of the body mounting portion 71. The body mounting portion 71 includes flow path forming protrusions 71a at four locations on its inner circumferential surface that contact the outer circumferential surface of the protrusion 53 of the cap body 30 to form a flow path (hereinafter referred to as the "first flow path") 20a for the contents between the inner circumferential surface of the body mounting portion 71 and the outer circumferential surface of the protrusion 53 of the cap body 30. The body mounting portion 71 includes two protrusions 71b that fit into the slip-out prevention grooves 52b (see FIG. 2(b)) of the cap body 30. The central protrusion 72 has flow path forming protrusions 72a at four locations on its outer surface that contact the inner surface of the protrusion 53 to form a flow path for the contents (hereinafter referred to as the "second flow path") 20b between the inner surface of the protrusion 53 and the outer surface of the central protrusion 72.

[0035] The nozzle tip 70 has a single internal passage type elliptical nozzle 73 in the center as a first nozzle, which has an elliptical shape when observed from the front while spraying the contents. The elliptical nozzle 73 communicates with the space on the inner periphery of the central protrusion 72. The space on the inner periphery of the central protrusion 72 forms a flow path for the contents (hereinafter referred to as the "third flow path") 20c.

[0036] The nozzle tip 70 has four nozzles 74 as second nozzles that spray the contents in a specific direction other than the front. The four nozzles 74 are arranged at equal intervals around the same circle (hereinafter referred to as the "nozzle arrangement circle") 70a (see FIG. 6). When observed from the front while spraying the contents, if the major axis of the elliptical shape of the content spray range of the elliptical nozzle 73 extends in the vertical direction, the four nozzles 74 consist of a nozzle 74 that sprays the contents in the upper left direction, a nozzle 74 that sprays the contents in the upper right direction, a nozzle 74 that sprays the contents in the lower left direction, and a nozzle 74 that sprays the contents in the lower right direction. A nozzle such as the nozzle 74 that sprays the contents in a specific direction other than the front generally requires a smaller flow rate of the contents to spray the contents than an internal passage type elliptical nozzle.

[0037] Next, spraying of the contents from the aerosol product 10 will be described.

[0038] A user can press the button 50. When the user presses the button 50, the button 50 presses a part of the valve of the aerosol product 10, causing the contents of the container to be expelled from the container via the valve.

[0039] The contents released from the container by the valve pass through flow path 50a of button portion 50, then flow from flow path 50a to opening 50b and into first flow path 20a, and from flow path 50a to openings 50c and into second flow path 20b and third flow path 20c. The contents introduced into first flow path 20a and second flow path 20b are sprayed in specific directions from four spray nozzles 74. The contents introduced into third flow path 20c are sprayed in an elliptical shape from elliptical nozzle 73.

[0040] Fig. 6(a) is a front view of the aerosol product 10 in the vicinity of the nozzle tip 70 when the contents are being sprayed. Fig. 6(b) is a side cross-sectional view of the aerosol product 10 in the vicinity of the nozzle tip 70 when the contents are being sprayed.

[0041] In Figure 6, the dashed line indicates the range of the contents being sprayed from the aerosol product 10. As shown in Figure 6, the aerosol product 10 can spray the contents in an elliptical shape from the elliptical nozzle 73, and can also spray the contents from the four nozzles 74 in specific directions.

[0042] As described above, the button-type cap 20 is equipped with an elliptical nozzle 73 that, when observed from the front, causes the spray range of the contents of the aerosol product 10 to be longer in the vertical direction than in any other direction, and a nozzle 74 that, when observed from the front, sprays the contents in a direction between the vertical direction and the left-right direction perpendicular to the vertical direction. Therefore, the elliptical nozzle 73 and nozzle 74 can realize a new shape for the spray range of the contents.

[0043] The content spraying devices described in Patent Documents 1 to 3 have three nozzles. However, the button cap 20 has a total of five nozzles, including the elliptical nozzle 73 and four nozzles 74. If the amount of content sprayed by the entire content spraying device is the same, the more nozzles there are, the smaller the nozzle diameter can be, thereby reducing the amount of content sprayed per nozzle. The smaller the amount of content sprayed per nozzle, the quieter the sound produced when the content is sprayed from the nozzle.

[0044] 7(a) is a front view of the aerosol product 10 when operated by a user with the left hand and the contents are being sprayed, and FIG. 7(b) is a front view of the aerosol product 10 when operated by a user with the right hand and the contents are being sprayed.

[0045] When observed from the front, the button cap 20 has a nozzle 74 that sprays the contents toward the upper left when the long axis of the elliptical shape, which is the shape of the spray range of the contents from the elliptical nozzle 73, extends in the up-down direction. Therefore, as shown in Fig. 7(a), when a user holds the aerosol product 10 in their left hand and operates the button cap 20 with their left hand to spray the contents toward the front, the spray range of the contents from the nozzle 74 is located in front of or near the position in front of the user's eyes. Similarly, when the up-down direction is up-down when observed from the front, the button cap 20 has a nozzle 74 that sprays the contents toward the upper right when the up-down direction is up-down. Therefore, as shown in Fig. 7(b), when a user holds the aerosol product 10 in their right hand and operates the button cap 20 with their right hand to spray the contents toward the front, the spray range of the contents from the nozzle 74 is located in front of or near the position in front of the user's eyes. Therefore, the button cap 20 can visually emphasize the spray of the contents to the user.

[0046] When observed from the front, the button-equipped cap 20 has an injection port 74 that injects the contents toward the upper left and an injection port 74 that injects the contents toward the upper right when the extension direction of the long axis of the elliptical shape, which is the shape of the spray range of the contents by the elliptical injection port 73, is in the vertical direction. With this configuration, the buttoned cap 20 has a spray range for the contents from the nozzle 74 that is located in front of or near the user's eyes, whether the user is holding the aerosol product 10 in his or her left hand and operating the buttoned cap 20 with his or her left hand to spray the contents straight ahead, or whether the user is holding the aerosol product 10 in his or her right hand and operating the buttoned cap 20 with his or her right hand to spray the contents straight ahead.Therefore, whether the user is holding the aerosol product 10 in his or her left hand and operating the buttoned cap 20 with his or her left hand to spray the contents straight ahead, or whether the user is holding the aerosol product 10 in his or her right hand and operating the buttoned cap 20 with his or her right hand to spray the contents straight ahead, the spraying of the contents can be visually emphasized to the user.

[0047] When button cap 20 is observed from the front, and the extension direction of the long axis of the elliptical shape, which is the shape of the spray range of the contents by elliptical nozzle 73, is in the vertical direction, it is equipped with nozzle 74 that sprays the contents in the upper left direction, nozzle 74 that sprays the contents in the upper right direction, nozzle 74 that sprays the contents in the lower left direction, and nozzle 74 that sprays the contents in the lower right direction, so that it is possible to spray the contents over a wide range while realizing a new shape as the shape of the spray range of the contents.

[0048] 6, the button cap 20 has four nozzles 74 arranged at equal intervals on the circumference of the same nozzle arrangement circle 70a, so that the contents can be sprayed evenly over a wide area while realizing a new shape as the shape of the spray range of the contents. Note that although the button cap 20 has four nozzles 74 arranged on the circumference of the same nozzle arrangement circle 70a, they do not have to be arranged at equal intervals, and the four nozzles 74 do not have to be arranged on the circumference of the same circle.

[0049] FIG. 8 is a front view of a portion of the cap body 30 in a configuration different from that shown in FIG. 2( a ).

[0050] In this embodiment, the protrusion 53 is annular. However, the protrusion 53 does not have to be annular. For example, the protrusion 53 may be divided into portions for each injection port 74, as shown in FIG. 8 .

[0051] The button-equipped cap 20 may not have at least one of the four injection ports 74 .

[0052] The button cap 20 may be provided with an elliptical nozzle of a type other than the internal passage type as the first nozzle, instead of the internal passage type elliptical nozzle 73 .

[0053] Fig. 9(a) is a front view of a nozzle tip 170 which is different from the nozzle tip 70. Fig. 9(b) is a rear view of the nozzle tip 170. Fig. 10(a) is a cross-sectional view taken along the line D-D in Fig. 9(a). Fig. 10(b) is a cross-sectional view taken along the line E-E in Fig. 9(a).

[0054] The buttoned cap 20 may be provided with a nozzle tip 170 shown in FIGS. 9 and 10 instead of the nozzle tip 70 (see FIGS. 3 to 5).

[0055] 9 and 10, the configuration of the nozzle tip 170 is the same as that of the nozzle tip 70, except that it is provided with a baffle-type elliptical nozzle 173 as a first nozzle that forms an elliptical spray area for the contents when observed from the front while the contents are being sprayed, instead of the elliptical nozzle 73 (see FIGS. 3 and 4). A baffle-type elliptical nozzle generally requires a larger flow rate of the contents to spray the contents in an elliptical shape than an internal passage-type elliptical nozzle.

[0056] When the button cap 20 is equipped with a nozzle tip 170 instead of the nozzle tip 70, the aerosol product 10 can spray the contents in an elliptical shape from the elliptical nozzle 173, just as when the button cap 20 is equipped with the nozzle tip 70, and can spray the contents from the four nozzles 74 in specific directions, respectively.

[0057] When the first nozzle, whose spray range for the contents is longer in the vertical direction than in any other direction when observed from the front, is an elliptical nozzle, the shape of the spray range for the contents from the first nozzle can be made into a well-balanced shape. However, the button cap 20 may be provided with a nozzle other than an elliptical nozzle as the first nozzle, whose spray range for the contents is longer in the vertical direction than in any other direction when observed from the front.

[0058] In this embodiment, the button cap 20 is provided on an aerosol product. However, the button cap 20 may also be provided on a pump product to spray the contents inside the container of the pump product.
