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 in that, when observed from the front, it has a plurality of nozzles 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, and each of the plurality of nozzles has at least a portion of its contents spray range overlapping with at least one of the other nozzles.

[0007] With this configuration, the contents spraying device of the present invention has a plurality of nozzles each having at least a portion of its spray range overlapping with at least one of the other nozzles, thereby enabling a novel shape to be realized as the shape of the contents spray range.

[0008] In the contents ejection device of the present invention, the plurality of ejection ports may be three or more and may be arranged at equal intervals on the circumference of the same circle.

[0009] 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.

[0010] In the contents spraying device of the present invention, the axis of the nozzle extending in the specific direction of the spray range of the contents when observed from the front does not have to pass through the center of the circle.

[0011] With this configuration, the content spraying device of the present invention can realize a novel shape for the content spraying range, since the axis extending in the longest direction of the content spraying range when observed from the front does not pass through the center of the circle in which the multiple nozzles are arranged.

[0012] In the contents spraying device of the present invention, the nozzle may be an elliptical nozzle in which the shape of the spray range of the contents when observed from the front is elliptical.

[0013] With this configuration, the contents ejection device of the present invention can realize a novel shape for the ejection range of the contents.

[0014] The pump-type product of the present invention is characterized by comprising the above-mentioned content ejection device and the content.

[0015] 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.

[0016] The aerosol product of the present invention is characterized by comprising the above-mentioned content spraying device and the content.

[0017] This configuration allows the aerosol product of the present invention to realize a novel shape for the spray range of the contents.

[0018] 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.

[0020] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0021] First Embodiment First, the configuration of an aerosol product according to a first embodiment of the present invention will be described.

[0022] 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.

[0023] 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.

[0024] 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.

[0025] 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.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] 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).

[0030] 1, 3, and 4, 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.

[0031] The nozzle tip 70 is equipped with six baffle-type elliptical nozzles 73, which form an elliptical spray area for the contents when observed from the front while the contents are being sprayed. The six elliptical nozzles 73 are arranged at equal intervals on the circumference of the same circle (hereinafter referred to as the "elliptical nozzle arrangement circle") 70a (see FIG. 5). When the contents are being sprayed, the elliptical nozzles 73 form an elliptical spray area whose major axis does not pass through the center 70b (see FIG. 5) of the elliptical nozzle arrangement circle 70a.

[0032] Next, spraying of the contents from the aerosol product 10 will be described.

[0033] 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.

[0034] The contents released from the container by the valve pass through flow path 50a of button portion 50, and are then introduced from flow path 50a through opening 50b into first flow path 20a, and from flow path 50a through opening 50c into second flow path 20b. The contents introduced into first flow path 20a and second flow path 20b are sprayed in an elliptical shape from each of six elliptical nozzles 73.

[0035] Fig. 5(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. 5(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.

[0036] In Figure 5, the dashed lines indicate the range of the contents being sprayed from the aerosol product 10. As shown in Figure 5, the aerosol product 10 can spray the contents in an elliptical shape from each of the six elliptical nozzles 73.

[0037] As explained above, as shown in Figure 5, each of the six elliptical nozzles 73 of the button-equipped cap 20 has a spray range that partially overlaps with the other four elliptical nozzles 73, so that a novel shape can be realized as the shape of the spray range of the contents.

[0038] 5, the button cap 20 has six elliptical nozzles 73 arranged at equal intervals on the circumference of the same elliptical nozzle arrangement circle 70a, so that the contents can be sprayed over a wide range while realizing a novel shape as the shape of the spray range of the contents. Note that the button cap 20 does not need to have the six elliptical nozzles 73 arranged on the circumference of the same circle.

[0039] 5, when viewed from the front, the shape of the spray range of the elliptical nozzle 73 of the button cap 20 is an ellipse whose major axis does not pass through the center 70b of the elliptical nozzle arrangement circle 70a on which the six elliptical nozzles 73 are arranged, so the shape of the spray range of the contents becomes closer to a circle, and a new shape can be realized as the shape of the spray range of the contents. Note that when viewed from the front, the shape of the spray range of the elliptical nozzle 73 of the button cap 20 may also be an ellipse whose major axis passes through the center 70b of the elliptical nozzle arrangement circle 70a on which the six elliptical nozzles 73 are arranged.

[0040] FIG. 6 is a front view of a portion of the cap body 30 in a configuration different from that shown in FIG. 2( a ).

[0041] 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 individual elliptical nozzle holes 73 as shown in FIG. 6 .

[0042] In this embodiment, the nozzle tip 70 corresponds to six elliptical nozzles 73. However, the nozzle tip 70 may correspond to a number of elliptical nozzles 73 other than six. When the amount of content sprayed from the entire button cap 20 is the same, the more elliptical nozzles 73 there are, the smaller the orifices of the elliptical nozzles 73 can be made, thereby reducing the amount of content sprayed from each orifice. The smaller the amount of content sprayed from each orifice, the quieter the sound made when the content is sprayed from the orifice.

[0043] The button cap 20 may be provided with an elliptical nozzle of a type other than the baffle type instead of the baffle type elliptical nozzle 73 .

[0044] Fig. 7(a) is a front view of a nozzle tip 170 which is different from the nozzle tip 70. Fig. 7(b) is a rear view of the nozzle tip 170. Fig. 8(a) is a cross-sectional view taken along the line CC in Fig. 7(a). Fig. 8(b) is a cross-sectional view taken along the line DD in Fig. 7(a).

[0045] The button cap 20 may be provided with a nozzle tip 170 shown in FIGS. 7 and 8 in place of the nozzle tip 70 (see FIGS. 3 and 4).

[0046] As shown in Figures 7 and 8, the nozzle tip 170 has a configuration similar to that of the nozzle tip 70, except that it is equipped with internal passage-type elliptical nozzles 173, which form an elliptical spray area for the contents when observed from the front during spraying. The six elliptical nozzles 173 are arranged at equal intervals around the same elliptical nozzle arrangement circle. When observed from the front during spraying, the elliptical nozzles 173 form an elliptical spray area for the contents, with the major axis of the elliptical nozzle arrangement circle not passing through the center of the elliptical nozzle arrangement circle. An internal passage-type elliptical nozzle generally requires a smaller flow rate of the contents to spray the contents in an elliptical shape than a baffle-type elliptical nozzle.

[0047] When the button cap 20 of the aerosol product 10 is equipped with a nozzle tip 170 instead of the nozzle tip 70, the contents can be sprayed in an elliptical shape from the six elliptical nozzles 173, just as when the button cap 20 is equipped with a nozzle tip 70.

[0048] When the nozzle of button cap 20 has an elliptical nozzle whose spray range of the contents in a specific direction is longer than all other directions when observed from the front, the shape of the spray range of the contents from the nozzle can be made into a well-balanced shape. However, button cap 20 may also have an nozzle other than an elliptical nozzle as the nozzle whose spray range of the contents in a specific direction is longer than all other directions when observed from the front.

[0049] 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.

[0050] Second Embodiment First, the configuration of an aerosol product according to a second embodiment of the present invention will be described.

[0051] Among the components of the aerosol product according to this embodiment, those components that are similar to those of the aerosol product 10 according to the first embodiment (see Figure 1) are given the same reference numerals as those of the aerosol product 10, and detailed explanations thereof will be omitted.

[0052] Figure 9(a) is a front view of a nozzle tip 270 of an aerosol product according to this embodiment, and Figure 9(b) is a rear view of the nozzle tip 270.

[0053] The configuration of the aerosol product according to this embodiment is similar to that of aerosol product 10, except that nozzle tip 270 shown in FIG. 9 is provided instead of nozzle tip 70 (see FIG. 3).

[0054] As shown in Figure 9, the configuration of the nozzle tip 270 is the same as that of the nozzle tip 70, except that three baffle-type elliptical nozzles 273, the shape of which is an ellipse in the spray range of the contents when observed from the front while the contents are being sprayed, have a major axis extending in the direction of the extension of the elliptical nozzle arrangement circle 270a (see Figure 10) and a major axis extending in the direction of the extension of the elliptical nozzle arrangement circle 70a (see Figure 5(a)), and the shape of which is an ellipse in the spray range of the contents when observed from the front while the contents are being sprayed, have been replaced with six baffle-type elliptical nozzles 73 (see Figure 5(a)), the shape of which is an ellipse in the spray range of the contents when observed from the front while the contents are being sprayed. The three elliptical nozzles 273 are arranged at equal intervals on the circumference of the same elliptical nozzle arrangement circle 270a.

[0055] Next, spraying of the contents from the aerosol product according to this embodiment will be described.

[0056] A user can press button 50. In the aerosol product according to this embodiment, when button 50 is pressed by a user, button 50 presses a part of the valve, causing the contents inside the container to be expelled to the outside of the container via the valve.

[0057] The contents released from the container by the valve pass through flow path 50a of button portion 50, and are then introduced from flow path 50a through opening 50b into first flow path 20a, and from flow path 50a through opening 50c into second flow path 20b. The contents introduced into first flow path 20a and second flow path 20b are sprayed in an elliptical shape from each of three elliptical nozzles 273.

[0058] Fig. 10(a) is a front view of the aerosol product in the vicinity of the nozzle tip 270 when the contents are being sprayed. Fig. 10(b) is a side cross-sectional view of the aerosol product in the vicinity of the nozzle tip 270 when the contents are being sprayed.

[0059] In Figure 10, the dashed lines indicate the range of the contents being sprayed from the aerosol product according to this embodiment. As shown in Figure 10, the aerosol product according to this embodiment can spray the contents in an elliptical shape from each of the three elliptical nozzles 273.

[0060] As described above, in the button-equipped cap of this embodiment, as shown in Figure 10, each of the three elliptical nozzles 273 has a spray range that partially overlaps with the other two elliptical nozzles 273, so that a new shape can be realized as the shape of the spray range of the contents.

[0061] 10, the button cap according to this embodiment has three elliptical nozzles 273 arranged at equal intervals on the circumference of the same elliptical nozzle arrangement circle 270a, so that the contents can be sprayed over a wide area while realizing a new shape as the shape of the spray range of the contents. Note that the button cap according to this embodiment does not need to have the three elliptical nozzles arranged on the circumference of the same circle.

[0062] In this embodiment, the protrusion 53 is annular, but the protrusion 53 does not have to be annular.

[0063] In this embodiment, the nozzle tip 270 corresponds to three elliptical nozzles 273. However, the nozzle tip 270 may correspond to a number of elliptical nozzles 273 other than three. When the amount of content sprayed from the entire button cap according to this embodiment is the same, the more elliptical nozzles 273 there are, the smaller the orifices of the elliptical nozzles 273 can be made, thereby reducing the amount of content sprayed from each orifice. The smaller the amount of content sprayed from each orifice, the quieter the sound produced when the content is sprayed from the orifice.

[0064] The button cap according to this embodiment may be provided with an elliptical nozzle of a type other than the baffle type, instead of the baffle type elliptical nozzle 273. For example, the button cap according to this embodiment may be provided with an internal passage type elliptical nozzle, instead of the baffle type elliptical nozzle 273.

[0065] In the button cap according to this embodiment, when the nozzle whose spray range of the contents is longer in a specific direction than in all directions other than the specific direction when observed from the front is an elliptical nozzle, the shape of the spray range of the contents from the nozzle can be made to be a well-balanced shape. However, the button cap according to this embodiment may also be provided with a nozzle other than an elliptical nozzle as the nozzle whose spray range of the contents is longer in a specific direction than in all directions other than the specific direction when observed from the front.

[0066] The button cap according to the present embodiment is provided on an aerosol product in this embodiment, but may also be provided on a pump product to spray the contents inside the container of the pump product.
