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 includes a nozzle tip with two orifices for spraying the contents of a pump-type product, and an annular spray protrusion that, together with the nozzle tip, forms a mechanical breakup mechanism for each orifice to apply a swirling force to the contents and spray the contents from the orifice in a mist form (see, for example, Patent Document 1). Each of the mechanical breakup mechanisms of the content spraying device described in Patent Document 1 includes a swirling chamber in which the contents swirl, and first and second inlet passages for introducing the contents into the swirling chamber so that the contents swirl in the swirling chamber. The first and second inlet passages of the mechanical breakup mechanism of the content spraying device described in Patent Document 1 introduce the contents from a flow path on the inner periphery of the spray protrusion.

[0003] Japanese Utility Model Application Publication No. 62-103459

[0004] However, conventional content ejection devices have a problem in that the size of each of the multiple mechanical breakup mechanisms in the circumferential direction is large.

[0005] Therefore, an object of the present invention is to provide a content ejection device, a pump-type product, and an aerosol-type product that can reduce the size of each of multiple mechanical breakup mechanisms in the circumferential direction.

[0006] The contents spraying device of the present invention comprises a nozzle tip having multiple orifices arranged on the circumference of the same circle for spraying the contents of a pump-type product or an aerosol-type product, and a spray protrusion that, together with the nozzle tip, forms a mechanical breakup mechanism for each of the orifices to apply a swirling force to the contents to spray the contents in a mist from the orifice, the mechanical breakup mechanism comprising the orifice, a swirling chamber in which the contents swirl, and a first inlet path and a second inlet path for introducing the contents into the swirling chamber so that the contents swirl in the swirling chamber, the first inlet path introducing the contents from the side opposite the center of the circle relative to the spray protrusion, and the second inlet path introducing the contents from the center side of the spray protrusion.

[0007] With this configuration, in each of the multiple mechanical breakup mechanisms of the contents injection device of the present invention, the contents are introduced into the first inlet passage from the side opposite the center of the circle where the multiple orifices are arranged relative to the injection protrusion, and the contents are introduced into the second inlet passage from the center of the circle where the multiple orifices are arranged relative to the injection protrusion, thereby making it possible to reduce the size of each of the multiple mechanical breakup mechanisms in the circumferential direction.

[0008] In the contents ejection device of the present invention, the orifices arranged at equal intervals on the circumference of the circle may be three or more in number and may be arranged at equal intervals on the circumference of the 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 content injection device of the present invention, the injection protrusion is annular, and the groove for forming the swirling chamber, the groove for forming the first inlet passage, and the groove for forming the second inlet passage may be formed only on the nozzle tip out of the nozzle tip and the injection protrusion.

[0011] With this configuration, the content ejection device of the present invention can reduce the accuracy required for circumferential alignment of the ejection protrusion and the nozzle tip.

[0012] The content ejection device of the present invention may have an ejection port for ejecting the content inside the circle.

[0013] With this configuration, the contents ejection device of the present invention has an ejection port inside the circle in which the orifices of the multiple mechanical breakup mechanisms are arranged, thereby making it possible to realize a novel shape for the shape of the contents ejection range.

[0014] In the contents ejection device of the present invention, when observed from the front, the ejection port may have a range in which the contents are ejected that is longer in a specific direction than in all directions other than the specific direction.

[0015] With this configuration, the contents spraying device of the present invention has a spray nozzle inside the circle in which the orifices of the multiple mechanical breakup mechanisms are arranged, and the spray range of the contents is longer in a specific direction than in all other directions when observed from the front, making it possible to realize a novel shape for the shape of the spray range of the contents.

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

[0017] With this configuration, the contents spraying device of the present invention has an elliptical nozzle inside the circle in which the orifices of the multiple mechanical breakup mechanisms are arranged, so that the shape of the contents spray range when observed from the front is elliptical, thereby making it possible to realize a novel shape for the shape of the contents spray range.

[0018] In the contents ejection device of the present invention, the specific direction may be an up-down direction.

[0019] With this configuration, the contents spraying device of the present invention has an injection port that is longer in the vertical direction than in any other direction when observed from the front, and is located inside the circle in which the orifices of the multiple mechanical breakup mechanisms are arranged, making it possible to realize a novel shape for the shape of the contents spraying range.

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

[0021] With this configuration, the pump-type product of the present invention can reduce the size of each of the multiple mechanical break-up mechanisms in the circumferential direction.

[0022] The aerosol product of the present invention is characterized by comprising the above-mentioned content spraying device and the content.

[0023] This configuration allows the aerosol product of the present invention to reduce the size of each of the multiple mechanical break-up mechanisms in the circumferential direction.

[0024] The content ejection device, pump-type product, and aerosol-type product of the present invention can reduce the size of each of the multiple mechanical breakup mechanisms in the circumferential direction.

[0026] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0027] First Embodiment First, the configuration of a pump-type product according to a first embodiment of the present invention will be described.

[0028] Fig. 1(a) is a front view of a portion of a pump-type product 10 according to the present embodiment, and Fig. 1(b) is a side cross-sectional view of a portion of the pump-type product 10.

[0029] As shown in Figure 1, pump-type product 10 comprises a container (not shown) that holds contents to be dispensed to the outside, a pump (not shown) that is attached to the container and dispenses the contents inside the container to the outside of the container when a part of the pump is pressed, and a button 20 that serves as a contents spraying device that is attached to the pump to press a part of the pump and sprays the contents dispensed to the outside of the container by the pump.

[0030] The button 20 includes a button body 30 that is attached to the pump, and a nozzle tip 40 that is attached to the button body 30 for spraying the contents.

[0031] 2A is a front view of a portion of the button body 30. FIG. 2B is a side cross-sectional view of a portion of the button body 30.

[0032] As shown in FIGS. 1 and 2 , the button body 30 includes a pump mounting portion 31 that is attached to the pump, a tip mounting portion 32 that has a circular hole (hereinafter referred to as the “tip insertion hole”) 32a into which the nozzle tip 40 is inserted, and to which the nozzle tip 40 is attached by inserting the nozzle tip 40 into the tip insertion hole 32a, and an ejection protrusion 33 that, together with the nozzle tip 40, forms four mechanical breakup mechanisms 21 for applying a swirling force to the contents near an orifice 40a (described below) of the nozzle tip 40, thereby ejecting the contents in a mist form from the orifice 40a. The tip insertion hole 32a has two grooves (hereinafter referred to as “removal prevention grooves”) 32b that fit into portions of the nozzle tip 40 to prevent the nozzle tip 40 from coming out of the tip insertion hole 32a. The ejection protrusion 33 is annular and is disposed inside the tip insertion hole 32a of the tip mounting portion 32.

[0033] The button body 30 is formed with a flow path 30a through which the contents discharged from the pump attached to the pump attachment portion 31 flow, two openings 30b for connecting the flow path 30a to the space on the inner periphery of the tip attachment portion 32 and on the outer periphery of the injection protrusion portion 33, and an opening 30c for connecting the flow path 30a to the space on the inner periphery of the injection protrusion portion 33.

[0034] 3A is a rear view of the nozzle tip 40. FIG. 3B is a side cross-sectional view of the nozzle tip 40.

[0035] As shown in FIGS. 1 and 3 , the nozzle tip 40 has four orifices 40a arranged at equal intervals around the same circle 40e (see FIG. 4 ). The nozzle tip 40 includes an annular body attachment portion 41 whose outer periphery is attached to the tip attachment portion 32 of the button body 30, and an annular central protrusion 42 arranged on the inner periphery of the body attachment portion 41. The body attachment portion 41 includes four flow path-forming protrusions 41a on its inner periphery that contact the outer periphery of the ejection protrusion 33 of the button body 30 to form a flow path (hereinafter referred to as the “first flow path”) 20a for the contents between the inner periphery of the body attachment portion 41 and the outer periphery of the ejection protrusion 33 of the button body 30. The body attachment portion 41 also includes two protrusions 41b that fit into the slip-out prevention grooves 32b (see FIG. 2( b)) of the button body 30. The central protrusion 42 has flow path forming protrusions 42a at four locations on its outer surface that come into contact with the inner surface of the injection protrusion 33 to form a flow path for the contents (hereinafter referred to as the "second flow path") 20b between the inner surface of the injection protrusion 33 and the outer surface of the central protrusion 42.

[0036] 1 to 3, each of the four mechanical breakup mechanisms 21 includes an orifice 40a, a swirl chamber 21a in which the contents swirl, and a first inlet passage 21b and a second inlet passage 21c for introducing the contents into the swirl chamber 21a so that the contents swirl in the swirl chamber 21a. The first inlet passage 21b communicates with the first flow path 20a. The second inlet passage 21c communicates with the second flow path 20b. The button 20 includes four mechanical breakup mechanisms 21 spaced equally apart on the circumference of a single circle 40e (see FIG. 4). The nozzle tip 40 is formed with a swirling chamber groove 40b for forming the swirling chamber 21a together with the end 33a of the injection protrusion 33, a first inlet passage groove 40c for forming the first inlet passage 21b together with the end 33a of the injection protrusion 33, and a second inlet passage groove 40d for forming the second inlet passage 21c together with the end 33a of the injection protrusion 33.

[0037] Next, spraying of the contents by the pump-type product 10 will be described.

[0038] A user can press the button 20. When the user presses the button 20, the pump product 10 presses a part of the pump, causing the contents of the container to be expelled from the container by the pump.

[0039] The contents discharged from the container by the pump pass through flow path 30a of button 20, then are introduced from flow path 30a through opening 30b into first flow path 20a, and from flow path 30a through opening 30c into second flow path 20b. The contents introduced into first flow path 20a are introduced from first flow path 20a through first inlet path 21b into swirling chamber 21a. The contents introduced into second flow path 20b are introduced from second flow path 20b through second inlet path 21c into swirling chamber 21a. Therefore, the contents introduced into swirling chamber 21a through first inlet path 21b and second inlet path 21c swirl within swirling chamber 21a and are sprayed in mist form from orifice 40a.

[0040] Fig. 4(a) is a front view of the vicinity of the nozzle tip 40 of the pump-type product 10 when the contents are being sprayed. Fig. 4(b) is a side cross-sectional view of the vicinity of the nozzle tip 40 of the pump-type product 10 when the contents are being sprayed.

[0041] In Figure 4, the dashed lines indicate the range of the contents being sprayed from the pump-type product 10. As shown in Figure 4, the pump-type product 10 can spray the contents in a mist form over a wide area from the four orifices 40a.

[0042] As described above, in each of the four mechanical breakup mechanisms 21 of the button 20, of the first inlet passage 21b and the second inlet passage 21c for introducing the contents into the swirling chamber 21a, the contents are introduced into the first inlet passage 21b from the side opposite the center 40f of the circle 40e (see Figure 4) with respect to the injection protrusion 33, i.e., from the first flow path 20a on the outer periphery of the injection protrusion 33, and the contents are introduced into the second inlet passage 21c from the side of the center 40f of the circle 40e with respect to the injection protrusion 33, i.e., from the second flow path 20b on the inner periphery of the injection protrusion 33, so that the size of each of the four mechanical breakup mechanisms 21 in the circumferential direction can be reduced.

[0043] The ejection protrusion 33 is annular. The swirl chamber groove for forming the swirl chamber 21a, the first introduction passage groove for forming the first introduction passage 21b, and the second introduction passage groove for forming the second introduction passage 21c are formed only on the nozzle tip 40 out of the nozzle tip 40 and the ejection protrusion 33. With this configuration, the button 20 can reduce the accuracy required for circumferential alignment of the ejection protrusion 33 and the nozzle tip 40.

[0044] FIG. 5 is a front view of a part of the button body 30 in a configuration different from that shown in FIG. 2( a ).

[0045] In this embodiment, the ejection protrusion 33 is annular. However, the ejection protrusion 33 does not have to be annular. For example, the ejection protrusion 33 may be divided into parts for each mechanical breakup mechanism 21, as shown in FIG. 5 .

[0046] Figure 6(a) is a rear view of the nozzle tip 40 in a configuration different from that shown in Figure 3(a). Figure 6(b) is a rear view of the nozzle tip 40 in a configuration different from that shown in Figures 3(a) and 6(a).

[0047] In this embodiment, the nozzle tip 40 corresponds to four mechanical breakup mechanisms 21. However, the nozzle tip 40 may correspond to a number other than four mechanical breakup mechanisms 21. For example, the nozzle tip 40 may correspond to three mechanical breakup mechanisms 21 as shown in FIG. 6( a) or six mechanical breakup mechanisms 21 as shown in FIG. 6( b). When the ejection amount of the contents from the entire button 20 is the same, the more mechanical breakup mechanisms 21 there are, the smaller the diameter of the orifices 40 a of the mechanical breakup mechanisms 21 can be, thereby reducing the ejection amount of the contents from each orifice 40 a. The smaller the ejection amount of the contents from each orifice 40 a, the quieter the sound generated when the contents are ejected from the orifices 40 a.

[0048] When the button 20 has three or more orifices 40a and all of the orifices 40a are arranged at equal intervals around the circumference of the circle 40e, the button 20 can spray the contents over a wide area while achieving a novel shape for the spray range of the contents, compared to when the button 20 has only two orifices 40a, when the button 20 has three or more orifices 40a and all of the orifices 40a are arranged around the circumference of the circle 40e but are not arranged at equal intervals, or when the button 20 has three or more orifices 40a and all of the orifices 40a are not arranged around the same circle.

[0049] In this embodiment, the swirl chamber groove for forming the swirl chamber 21a, the first introduction passage groove for forming the first introduction passage 21b, and the second introduction passage groove for forming the second introduction passage 21c are formed in the nozzle tip 40. However, it is sufficient that the swirl chamber groove for forming the swirl chamber 21a, the first introduction passage groove for forming the first introduction passage 21b, and the second introduction passage groove for forming the second introduction passage 21c are formed in at least one of the end 33a of the injection protrusion 33 and the nozzle tip 40.

[0050] In this embodiment, the button 20 is provided on a pump product, however, the button 20 may also be provided on an aerosol product to spray the contents inside the container of the aerosol product.

[0051] Second Embodiment First, the configuration of an aerosol product according to a second embodiment of the present invention will be described.

[0052] Among the components of the aerosol product according to this embodiment, those components that are similar to the components of the pump-type product 10 according to the first embodiment (see Figure 1) are given the same symbols as the components of the pump-type product 10, and detailed explanations will be omitted.

[0053] Figure 7(a) is a plan view of a portion of an aerosol product 110 according to this embodiment, and Figure 7(b) is a side cross-sectional view of a portion of the aerosol product 110.

[0054] As shown in Figure 7, the aerosol product 110 comprises a container (not shown) containing the contents to be released to the outside, a valve (not shown) attached to the container and releasing the contents from the container to the outside when a part of the valve is pressed, and a button-equipped cap 120 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.

[0055] The button cap 120 includes a cap body 130 that is attached to the container, and a nozzle tip 140 that is attached to the cap body 130 for spraying the contents.

[0056] The cap body 130 comprises a container attachment portion 131 that is attached to the container, a button portion 132 that has a configuration similar to that of the button body 30 (see Figure 1), and a flexible support portion 133 that is flexible and supports the button portion 132 side so that it can move relative to the container attachment portion 131 side.

[0057] Fig. 8(a) is a front view of the nozzle tip 140. Fig. 8(b) is a rear view of the nozzle tip 140. Fig. 9(a) is a plan cross-sectional view of the nozzle tip 140. Fig. 9(b) is a side cross-sectional view of the nozzle tip 140.

[0058] 7 to 9, the nozzle tip 140 has a configuration similar to that of the nozzle tip 40 (see FIG. 3), which is equipped with a baffle-type elliptical nozzle 141 such that, when observed from the front while the contents are being sprayed, the shape of the spray range of the contents is an ellipse with its major axis extending in the vertical direction. The elliptical nozzle 141 communicates with the space on the inner periphery of the central protrusion 42. The space on the inner periphery of the central protrusion 42 forms a flow path for the contents (hereinafter referred to as the "third flow path") 20c.

[0059] Next, spraying of the contents from the aerosol product 110 will be described.

[0060] A user can press button portion 132. When button portion 132 is pressed by a user, button portion 132 presses a part of the valve of aerosol product 110, causing the contents of the container to be expelled from the container via the valve.

[0061] The contents released from the container by the valve pass through the flow path 30a of the button portion 132, and are then introduced from the flow path 30a through the opening 30b into the first flow path 20a, and from the flow path 30a through the opening 30c into the second flow path 20b and the third flow path 20c.

[0062] The contents introduced into first flow path 20a are introduced from first flow path 20a into swirling chamber 21a via first inlet path 21b. The contents introduced into second flow path 20b are introduced from second flow path 20b into swirling chamber 21a via second inlet path 21c. Therefore, the contents introduced into swirling chamber 21a via first inlet path 21b and second inlet path 21c swirl within swirling chamber 21a and are sprayed in mist form from orifice 40a.

[0063] The content introduced into the third flow path 20c is sprayed in an elliptical shape from the elliptical nozzle 141.

[0064] Fig. 10(a) is a front view of the aerosol product 110 in the vicinity of the nozzle tip 140 when the contents are being sprayed. Fig. 10(b) is a side cross-sectional view of the aerosol product 110 in the vicinity of the nozzle tip 140 when the contents are being sprayed.

[0065] In Figure 10, the dashed lines indicate the range of the contents being sprayed from the aerosol product 110. As shown in Figure 10, the aerosol product 110 can spray the contents in a mist form over a wide area from the four orifices 40a, and can also spray the contents in an elliptical shape from the elliptical nozzle 141.

[0066] As described above, in each of the four mechanical breakup mechanisms 21 of the button-type cap 120, of the first inlet passage 21b and the second inlet passage 21c for introducing the contents into the swirling chamber 21a, the contents are introduced into the first inlet passage 21b from the side opposite the center 40f of the circle 40e with respect to the injection protrusion 33, i.e., from the first flow path 20a on the outer periphery of the injection protrusion 33, and the contents are introduced into the second inlet passage 21c from the side of the center 40f of the circle 40e with respect to the injection protrusion 33, i.e., from the second flow path 20b on the inner periphery of the injection protrusion 33, so that the size of each of the four mechanical breakup mechanisms 21 in the circumferential direction can be reduced.

[0067] The button-equipped cap 120 has an elliptical nozzle 141 as an injection port, which has an elliptical shape with the major axis extending in the vertical direction when observed from the front, inside the circle 40e in which the orifices 40a of the four mechanical breakup mechanisms 21 are arranged, so that a new shape can be realized as the shape of the injection range of the contents.

[0068] The button cap 120 may be provided with an injection port other than the elliptical injection port 141 as the injection port located inside the circle 40e in which the orifices 40a of the four mechanical breakup mechanisms 21 are arranged. For example, the button cap 120 may be provided with an elliptical injection port of a type other than a baffle type as the injection port located inside the circle 40e in which the orifices 40a of the four mechanical breakup mechanisms 21 are arranged, or may be provided with an elliptical injection port whose injection range for the contents when observed from the front is an ellipse with its major axis extending in a direction other than the up-and-down direction, or may be provided with an injection port that injects the contents in a specific direction other than the front direction, or may be provided with a simple round hole that injects the contents in the front direction, or may be provided with an orifice of a new mechanical breakup mechanism that is located inside the circle 40e in which the four mechanical breakup mechanisms 21 are arranged.

[0069] An example will be described in which the button-type cap 120 is provided with an elliptical nozzle of a type other than a baffle type, instead of the baffle type elliptical nozzle 141, as the nozzle located inside the circle 40e in which the orifices 40a of the four mechanical breakup mechanisms 21 are located.

[0070] Fig. 11(a) is a front view of a nozzle tip 240 which is different from the nozzle tip 140. Fig. 11(b) is a rear view of the nozzle tip 240. Fig. 12(a) is a plan cross-sectional view of the nozzle tip 240. Fig. 12(b) is a side cross-sectional view of the nozzle tip 240.

[0071] The button-equipped cap 120 may be provided with a nozzle tip 240 shown in FIGS. 11 and 12 instead of the nozzle tip 140 (see FIGS. 8 and 9).

[0072] 11 and 12, the nozzle tip 240 has a similar configuration to that of the nozzle tip 140, except that the nozzle tip 140 includes an internal passage-type elliptical nozzle 241, which serves as a nozzle orifice having an elliptical shape with its major axis extending in the vertical direction when observed from the front while spraying the contents. The elliptical nozzle 241 is connected to the third flow path 20c. The internal passage-type elliptical nozzle generally requires a smaller flow rate of the contents to spray the contents in an elliptical shape than the baffle-type elliptical nozzle.

[0073] When the button cap 120 is equipped with a nozzle tip 240 instead of the nozzle tip 140, the aerosol product 110 can spray the contents in a mist form over a wide area from the four orifices 40a, just as when the button cap 120 is equipped with the nozzle tip 140, and can also spray the contents in an elliptical shape from the elliptical nozzle 241.

[0074] An example will be described in which the button-type cap 120 is provided with an injection nozzle that sprays the contents in a specific direction other than the forward direction, instead of the elliptical injection nozzle 141, as an injection nozzle located inside the circle 40e in which the orifices 40a of the four mechanical breakup mechanisms 21 are located.

[0075] Fig. 13(a) is a front view of a nozzle tip 340 which is different from the nozzle tip 140 and the nozzle tip 240. Fig. 13(b) is a rear view of the nozzle tip 340. Fig. 14 is a side cross-sectional view of the nozzle tip 340.

[0076] The button cap 120 may be provided with a nozzle tip 340 shown in FIGS. 13 and 14 in place of the nozzle tip 140 (see FIGS. 8 and 9).

[0077] As shown in Figures 13 and 14, the nozzle tip 340 has a configuration similar to that of the nozzle tip 140, except that it has an outlet 341a that sprays the contents in a direction approximately 45 degrees upward when observed from the front, and an outlet 341b that sprays the contents in a direction approximately 45 degrees downward when observed from the front, instead of the elliptical nozzle 141 (see Figures 8 and 9). The outlets 341a and 341b are connected to the third flow path 20c. Orifices such as the outlets 341a and 341b that spray the contents in a specific direction other than the front generally require a lower flow rate of the contents to spray the contents compared to an internal passage type elliptical nozzle.

[0078] Fig. 15(a) is a front view of the aerosol product 110 in the vicinity of the nozzle tip 340 when the contents are being sprayed. Fig. 15(b) is a side cross-sectional view of the aerosol product 110 in the vicinity of the nozzle tip 340 when the contents are being sprayed.

[0079] In Figure 15, the dashed line indicates the range of the contents being sprayed from aerosol product 110. When button cap 120 is equipped with nozzle tip 340 instead of nozzle tip 140, aerosol product 110 can spray the contents in a mist form over a wide area from four orifices 40a, as shown in Figure 15, and can spray the contents from nozzle 341a in an upward angle of approximately 45 degrees and from nozzle 341b in a downward angle of approximately 45 degrees.

[0080] The ejection protrusion 33 is annular. The swirl chamber groove for forming the swirl chamber 21a, the first introduction passage groove for forming the first introduction passage 21b, and the second introduction passage groove for forming the second introduction passage 21c are formed only on the nozzle tips 140, 240, 340 out of the nozzle tips 140, 240, 340 and the ejection protrusion 33. With this configuration, the button cap 120 can reduce the accuracy required for circumferential alignment of the ejection protrusion 33 with the nozzle tips 140, 240, 340.

[0081] In this embodiment, the ejection protrusion 33 is annular. However, the ejection protrusion 33 does not have to be annular. For example, the ejection protrusion 33 may be divided into parts for each mechanical breakup mechanism 21.

[0082] In this embodiment, the nozzle tips 140, 240, and 340 correspond to four mechanical breakup mechanisms 21. However, the nozzle tips 140, 240, and 340 may correspond to a number of mechanical breakup mechanisms 21 other than four.

[0083] When the button-type cap 120 has three or more orifices 40a and all of the orifices 40a are arranged at equal intervals around the circumference of the circle 40e, it can spray the contents over a wide area while achieving a new shape for the spray range of the contents, compared to when it has only two orifices 40a, when it has three or more orifices 40a and all of the orifices 40a are arranged around the circumference of the circle 40e but are not arranged at equal intervals, or when it has three or more orifices 40a and all of the orifices 40a are not arranged around the same circle.

[0084] In the present embodiment, the swirl chamber groove for forming the swirl chamber 21a, the first introduction passage groove for forming the first introduction passage 21b, and the second introduction passage groove for forming the second introduction passage 21c are formed in the nozzle tips 140, 240, and 340. However, it is sufficient that the swirl chamber groove for forming the swirl chamber 21a, the first introduction passage groove for forming the first introduction passage 21b, and the second introduction passage groove for forming the second introduction passage 21c are formed in at least one of the end 33a of the injection protrusion 33 and the nozzle tip 140, 240, and 340.

[0085] In this embodiment, the button cap 120 is provided on an aerosol product, but the button cap 120 may also be provided on a pump product to spray the contents inside the container of the pump product.
