Abstract
Description
[Technical Field]
[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. [Background technology]
[0002] A conventional content spraying device is known that includes a nozzle with an orifice formed therein for spraying the contents of a pump-type product, and a cylindrical protrusion that can form, together with the nozzle, a mechanical breakup mechanism for applying a swirling force to the contents to spray the contents from the orifice in a mist form (see, for example, Patent Document 1). The content spraying device described in Patent Document 1 switches the mode of spraying the contents from the orifice by rotating the nozzle relative to the cylindrical protrusion. The orifice is positioned opposite the end of the cylindrical protrusion in the direction in which the cylindrical protrusion protrudes. The mechanical breakup mechanism of the content spraying device described in Patent Document 1 includes a swirling chamber in which the contents swirl, and first and second introduction paths for introducing the contents into the swirling chamber so that the contents swirl in the swirling chamber. The first and second introduction paths introduce the contents from the side opposite the center of the cylindrical protrusion. [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2011-177630 Summary of the Invention [Problem to be solved by the invention]
[0004] However, conventional content spraying devices have a problem in that they can only spray the content in a mist form from one orifice.
[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 spray the content in a mist form from multiple orifices. [Means for solving the problem]
[0006] The contents spraying device of the present invention comprises a nozzle having a plurality of orifices formed therein for spraying the contents of a pump-type product or an aerosol-type product, and an annular protrusion in which a mechanical breakup mechanism can be formed for each of the orifices together with the nozzle for applying a swirling force to the contents to spray the contents in a mist from the orifice, the mode of spraying the contents from the orifice being switched by rotating the nozzle relative to the annular protrusion, the plurality of orifices being positioned opposite the end of the annular protrusion in the direction of protrusion of the annular protrusion, the mechanical breakup mechanism comprising the orifice, 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 inlet passage introducing the contents from the side opposite the center of the annular protrusion with respect to the annular protrusion, and the second inlet passage introducing the contents from the center of the annular protrusion with respect to the annular protrusion.
[0007] With this configuration, the content spraying device of the present invention can form multiple mechanical breakup mechanisms each equipped with an orifice for spraying the contents of a pump-type product or an aerosol-type product, and can spray the contents in a mist form from the multiple orifices. Furthermore, in each of the multiple mechanical breakup mechanisms, the content spraying device of the present invention has a first inlet passage and a second inlet passage for introducing the contents into the swirl chamber, and the contents are introduced into the first inlet passage from the side opposite the center of the annular protrusion relative to the annular protrusion, and the contents are introduced into the second inlet passage from the center of the annular protrusion relative to the injection protrusion, thereby enabling the size of each of the multiple mechanical breakup mechanisms in the circumferential direction to be reduced.
[0008] In the content injection device of the present invention, the groove for the swirling chamber for forming the swirling chamber, the groove for the first inlet passage for forming the first inlet passage, and the groove for the second inlet passage for forming the second inlet passage may be formed only in the nozzle out of the nozzle and the annular protrusion.
[0009] With this configuration, the content injection device of the present invention has a swirling chamber groove for forming a swirling chamber, a first inlet passage groove for forming a first inlet passage, and a second inlet passage groove for forming a second inlet passage formed only in the nozzle out of the nozzle and the annular protrusion, thereby reducing the accuracy required for circumferential alignment of the nozzle and the annular protrusion.
[0010] In the contents injection device of the present invention, the mode includes a straight injection mode in which the contents are injected straight from the orifice, and the annular protrusion portion may be formed with a straight injection groove for introducing the contents into the swirl chamber groove when the mode is the straight injection mode.
[0011] With this configuration, the content injection device of the present invention has a straight injection groove formed in the annular protrusion, so that the mode of injection of the content from the orifice can be switched between a mode in which the content is sprayed in a mist from the orifice and a straight injection mode by rotating the nozzle relative to the annular protrusion.
[0012] In the contents injection device of the present invention, the straight injection groove may be configured such that the contents are introduced only from the center side of the annular protrusion, out of the opposite side and the center side.
[0013] With this configuration, the content sprayer of the present invention can simplify the structure of the flow path for the content when the content is sprayed straight from the orifice, compared to a content sprayer in which the straight spray groove introduces the content from both the side opposite the center of the annular protrusion and the center of the annular protrusion. Furthermore, with the content sprayer of the present invention, the flow of the content in the nozzle swirl chamber groove is one-way when the content is sprayed straight from the orifice, so the content can be sprayed more straightly from the orifice, compared to a content sprayer in which the straight spray groove introduces the content from both the side opposite the center of the annular protrusion and the center of the annular protrusion. Furthermore, with the content sprayer of the present invention, the area requiring airtightness between the nozzle and the annular protrusion is smaller, thereby improving airtightness, compared to a content sprayer in which the straight spray groove introduces the content from both the side opposite the center of the annular protrusion and the center of the annular protrusion.
[0014] In the contents injection device of the present invention, the straight injection groove may be configured such that the contents are introduced only from the opposite side of the annular protrusion, out of the opposite side and the center side.
[0015] With this configuration, the content sprayer of the present invention can simplify the structure of the flow path for the content when the content is sprayed straight from the orifice, compared to a content sprayer in which the straight spray groove introduces the content from both the side opposite the center of the annular protrusion and the center of the annular protrusion. Furthermore, with the content sprayer of the present invention, the flow of the content in the nozzle swirl chamber groove is one-way when the content is sprayed straight from the orifice, so the content can be sprayed more straightly from the orifice, compared to a content sprayer in which the straight spray groove introduces the content from both the side opposite the center of the annular protrusion and the center of the annular protrusion. Furthermore, with the content sprayer of the present invention, the area requiring airtightness between the nozzle and the annular protrusion is smaller, thereby improving airtightness, compared to a content sprayer in which the straight spray groove introduces the content from both the side opposite the center of the annular protrusion and the center of the annular protrusion. Furthermore, in the content injection device of the present invention, compared to a content injection device in which the straight injection groove is located on the side opposite the center of the annular protrusion and the center of the annular protrusion, and the contents are introduced only from the center side of the annular protrusion, the groove in the annular protrusion for introducing the contents into the mechanical breakup mechanism when the mode of injection of the contents from the orifice is a mode in which the contents are sprayed in a mist from the orifice and the straight injection groove in the annular protrusion are separated, thereby improving airtightness.
[0016] In the content spraying device of the present invention, the swirl chamber groove for forming the swirl chamber, the first inlet passage groove for forming the first inlet passage, and the second inlet passage groove for forming the second inlet passage are formed only on the annular protrusion out of the nozzle and the annular protrusion, the modes include a first mist spray mode in which the content is sprayed in a mist from the orifice, and a second mist spray mode in which the content is sprayed in a mist from the orifice at an angle narrower than that of the first mist spray mode, and the annular protrusion may have the swirl chamber groove, the first inlet passage groove, and the second inlet passage groove formed separately for the first mist spray mode and the second mist spray mode.
[0017] With this configuration, the content spraying device of the present invention can change the spray range by changing the width and depth of the groove for the swirling chamber, the groove for the first introduction path, and the groove for the second introduction path formed in the annular protrusion.Therefore, compared to content spraying devices that change the spray range by the width of the flow path to the mechanical breakup mechanism, this reduces the difference in force required for user operation when spraying the contents in a wide mist-like shape and when spraying the contents in a narrow mist-like shape, and makes it easier for developers to achieve the spray range they desire.
[0018] In the contents injection device of the present invention, the swirl chamber groove for forming the swirl chamber, the first inlet passage groove for forming the first inlet passage, and the second inlet passage groove for forming the second inlet passage are formed only on the annular protrusion out of the nozzle and the annular protrusion, the mode includes a straight injection mode in which the contents are injected straight from the orifice, and the annular protrusion may have a straight injection groove formed thereon for introducing the contents into the orifice when the mode is the straight injection mode.
[0019] With this configuration, the content injection device of the present invention has a straight injection groove formed in the annular protrusion for introducing the content into the orifice, so the content can be injected more directly from the orifice compared to a content injection device in which a straight injection groove for introducing the content into a swirling chamber groove for forming a swirling chamber of a mechanical breakup mechanism is formed in the annular protrusion.
[0020] The pump-type product of the present invention is characterized by comprising the above-mentioned content ejection device and the content.
[0021] This configuration allows the pump-type product of the present invention to spray its contents in a mist form from multiple orifices.
[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 spray its contents in a mist form from multiple orifices. [Effects of the Invention]

FIG. 3(a) is a front view of content spraying device 50 when a mechanical breakup mechanism 51 that sprays the contents in a mist at a wide angle is formed. FIG. 3(b) is a cross-sectional view taken along the arrow AA in FIG. 3(a).

[0034] As shown in Figures 1 to 5, the content spraying device 50 comprises an L-shaped pipe member 60 attached to the moving part 32 of the pump 30 to change the direction of travel of the contents discharged from the pump 30 by approximately 90 degrees, a nozzle 70 for spraying the contents, and a nozzle joint 80 attached to the L-shaped pipe member 60 to which the nozzle 70 is attached.
[0035] 3, the content spraying device 50 can have three mechanical breakup mechanisms 51 formed at equal intervals on the circumference of the same circle for applying a swirling force to the contents near an orifice 70a (described later) of the nozzle 70 to spray the contents in a mist form from the orifice 70a. Each of the three mechanical breakup mechanisms 51 includes the orifice 70a, a swirling chamber 51a in which the contents swirl, and a first introduction path 51b and a second introduction path 51c for introducing the contents into the swirling chamber 51a so that the contents swirl in the swirling chamber 51a.
[0036] 4, the content spraying device 50 can have three mechanical breakup mechanisms 52 formed at equal intervals on the same circle for applying a swirling force to the contents near the orifice 70a of the nozzle 70 to spray the contents in a mist form from the orifice 70a. The mechanical breakup mechanisms 52 are mechanisms for spraying the contents at a narrower angle than the mechanical breakup mechanism 51. Each of the three mechanical breakup mechanisms 52 includes an orifice 70a, a swirling chamber 52a in which the contents swirl, and a first introduction path 52b and a second introduction path 52c for introducing the contents into the swirling chamber 52a so that the contents swirl in the swirling chamber 52a.

[0038] 1 to 6, the L-shaped pipe member 60 includes a pump mounting portion 61 that is attached to the moving portion 32 of the pump 30, a plate-like portion 62 that comes into contact with and is pressed by the protrusion 42c of the handle 40, a first cylindrical portion 63 into which a first cylindrical portion 81 (described later) of the nozzle joint 80 is inserted, and a second cylindrical portion 64 that is disposed inside the first cylindrical portion 63 and is inserted into the first cylindrical portion 81 of the nozzle joint 80, into which a second cylindrical portion 82 (described later) of the nozzle joint 80 is inserted. The second cylindrical portion 64 is formed with a groove 64a into which a protrusion 81b (described later) of the nozzle joint 80 is inserted.
[0039] Fig. 7(a) is a front view of the nozzle 70. Fig. 7(b) is a rear view of the nozzle 70. Fig. 8 is a right side cross-sectional view of the nozzle 70.
[0040] As shown in Figures 1 to 5, 7 and 8, the nozzle 70 includes a first cylindrical portion 71, a second cylindrical portion 72 arranged inside the first cylindrical portion 71, a third cylindrical portion 73 arranged inside the second cylindrical portion 72, and a fourth cylindrical portion 74 arranged inside the third cylindrical portion 73.
[0041] The first cylindrical portion 71 is a portion that is operated by the user when the user rotates the nozzle 70 relative to the nozzle joint 80. Nine grooves 71a, into which protrusions 81b (described later) of the nozzle joint 80 fit, are arranged at equal intervals on the inner periphery of the first cylindrical portion 71.
[0042] The second cylindrical portion 72 is a portion into which a third cylindrical portion 83 of the nozzle joint 80, which will be described later, is inserted.
[0043] The third cylindrical portion 73 is a portion into which a fourth cylindrical portion 84 (described later) of the nozzle joint 80 is inserted by being inserted into the third cylindrical portion 83 of the nozzle joint 80. On the inner periphery of the third cylindrical portion 73, three grooves 73a are arranged at equal intervals on the circumference of the same circle.
[0044] The fourth cylindrical portion 74 is the portion that is inserted into the nozzle joint 80. On the outer periphery of the fourth cylindrical portion 74, three grooves 74a are arranged at equal intervals on the circumference of the same circle.
[0045] The nozzle 70 has three orifices 70a arranged at equal intervals on the circumference of the same circle. The orifices 70a are arranged at positions facing an end 84a of a fourth cylindrical portion 84 (described later) of the nozzle joint 80 in the protruding direction of the fourth cylindrical portion 84.
[0046] The nozzle 70 is formed with a swirl chamber groove 70b for forming the swirl chamber 51a of the mechanical breakup mechanism 51 or the swirl chamber 52a of the mechanical breakup mechanism 52 together with the end 84a of the fourth cylindrical portion 84 of the nozzle joint 80 (described later), a first introduction passage groove 70c for forming the first introduction passage 51b of the mechanical breakup mechanism 51 or the first introduction passage 52b of the mechanical breakup mechanism 52 together with the end 84a of the fourth cylindrical portion 84 of the nozzle joint 80, and a second introduction passage groove 70d for forming the second introduction passage 51c of the mechanical breakup mechanism 51 or the second introduction passage 52c of the mechanical breakup mechanism 52 together with the end 84a of the fourth cylindrical portion 84 of the nozzle joint 80.
[0047] Fig. 9(a) is a front view of the nozzle joint 80. Fig. 9(b) is a rear view of the nozzle joint 80. Fig. 10(a) is a right side view of the nozzle joint 80. Fig. 10(b) is a right side cross-sectional view of the nozzle joint 80. Fig. 10(c) is a plan cross-sectional view of the nozzle joint 80.
[0048] As shown in Figures 1 to 5, 9 and 10, the nozzle joint 80 comprises a first cylindrical portion 81 that is inserted into the first cylindrical portion 63 of the L-shaped pipe member 60 and into which the second cylindrical portion 64 of the L-shaped pipe member 60 is inserted, a second cylindrical portion 82 that is arranged inside the first cylindrical portion 81 and inserted into the second cylindrical portion 64 of the L-shaped pipe member 60, a third cylindrical portion 83 that is inserted into the second cylindrical portion 72 of the nozzle 70 and into which the third cylindrical portion 73 of the nozzle 70 is inserted, and a fourth cylindrical portion 84 that serves as an annular protrusion of the present invention that is arranged inside the third cylindrical portion 83 and inserted into the third cylindrical portion 73 of the nozzle 70 and into which the fourth cylindrical portion 74 of the nozzle 70 is inserted.
[0049] Two annular protrusions 81a are formed on the outer periphery of the first cylindrical portion 81 to make strong contact with the inner circumferential surface of the first cylindrical portion 63 of the L-shaped pipe member 60 to prevent the nozzle joint 80 from slipping out of the first cylindrical portion 63 of the L-shaped pipe member 60. A protrusion 81b is formed on the inner periphery of the first cylindrical portion 81 to be inserted into the groove 64a of the second cylindrical portion 64 of the L-shaped pipe member 60 to prevent the nozzle joint 80 from rotating relative to the L-shaped pipe member 60.
[0050] An annular protrusion 83a is formed on the outer periphery of the third cylindrical portion 83 to make strong contact with the inner surface of the second cylindrical portion 72 of the nozzle 70 to prevent it from slipping out of the second cylindrical portion 72 of the nozzle 70.
[0051] The fourth cylindrical portion 84 is formed with a mist wide-angle spray groove 84b for introducing the contents into the first introduction passage groove 70c of the nozzle 70 when the mode of spraying the contents from the orifice 70a (hereinafter referred to as the "content spray mode") is a mist wide-angle spray mode in which the contents are sprayed from the orifice 70a in a mist at a wide angle, and a mist wide-angle spray groove 84c for introducing the contents into the second introduction passage groove 70d of the nozzle 70 when the content spray mode is the mist wide-angle spray mode. Three mist wide-angle spray grooves 84b are formed at equal intervals on the circumference of the same circle on the outer circumferential surface of the fourth cylindrical portion 84 to communicate between the groove 73a of the third cylindrical portion 73 of the nozzle 70 and the first introduction passage 51b of the mechanical breakup mechanism 51. Three mist wide-angle injection grooves 84c are formed at equal intervals on the inner surface of the fourth cylindrical portion 84 of the nozzle 70 to connect the groove 74a of the fourth cylindrical portion 74 with the second introduction passage 51c of the mechanical breakup mechanism 51.
[0052] The fourth cylindrical portion 84 is formed with a mist narrow-angle spray groove 84d for introducing the contents into the first inlet passage groove 70c of the nozzle 70 when the content spray mode is a mist narrow-angle spray mode in which the contents are sprayed in a mist at a narrow angle from the orifice 70a, and a mist narrow-angle spray groove 84e for introducing the contents into the second inlet passage groove 70d of the nozzle 70 when the content spray mode is the mist narrow-angle spray mode. Three mist narrow-angle spray grooves 84d are formed at equal intervals on the circumference of the same circle on the outer circumferential surface of the fourth cylindrical portion 84 to connect the groove 73a of the third cylindrical portion 73 of the nozzle 70 with the first inlet passage 52b of the mechanical breakup mechanism 52. Three narrow-angle mist injection grooves 84e are formed at equal intervals on the inner surface of the fourth cylindrical portion 84 of the nozzle 70 to connect the groove 74a of the fourth cylindrical portion 74 to the second introduction passage 52c of the mechanical breakup mechanism 52.
[0053] Compared to groove 84b for wide-angle mist injection of nozzle joint 80, groove 84d for narrow-angle mist injection of nozzle joint 80 has a narrower width in the circumferential direction of fourth cylindrical portion 84 and a shallower depth in the radial direction of fourth cylindrical portion 84. In other words, the flow path formed by groove 84d for narrow-angle mist injection of nozzle joint 80 and the inner circumferential surface of third cylindrical portion 73 of nozzle 70 is narrower than the flow path formed by groove 84b for wide-angle mist injection of nozzle joint 80 and the inner circumferential surface of third cylindrical portion 73 of nozzle 70. Similarly, groove 84e for narrow-angle mist injection of nozzle joint 80 has a narrower width in the circumferential direction of fourth cylindrical portion 84 and a shallower depth in the radial direction of fourth cylindrical portion 84 than groove 84c for wide-angle mist injection of nozzle joint 80. In other words, the flow path formed by the groove 84e for narrow-angle mist injection of the nozzle joint 80 and the outer surface of the fourth cylindrical portion 74 of the nozzle 70 is narrower than the flow path formed by the groove 84c for wide-angle mist injection of the nozzle joint 80 and the outer surface of the fourth cylindrical portion 74 of the nozzle 70.
[0054] The nozzle joint 80 has three protrusions 85 that fit into the groove 71a of the first cylindrical portion 71 of the nozzle 70 and are arranged at equal intervals on the circumference of the same circle.
[0055] The nozzle joint 80 is formed with two flow paths 86 for passing the contents that have passed through the interior of the L-shaped pipe member 60 to the space between the third cylindrical portion 83 and the fourth cylindrical portion 84. The nozzle joint 80 is formed with a flow path 87 for passing the contents that have passed through the interior of the L-shaped pipe member 60 to the space inside the fourth cylindrical portion 84.
[0056] Next, the operation of the pump product 10 will be described.
[0057] The content spraying device 50 can switch content spraying modes by rotating the nozzle 70 relative to the fourth cylindrical portion 84 of the nozzle joint 80. The content spraying modes include a wide-angle mist spray mode, a narrow-angle mist spray mode, and a spray stop mode that stops spraying of the content from the orifice 70a.
[0058] First, the operation of the pump-type product 10 in the wide-angle mist spray mode will be described.
[0059] The user can place the content sprayer 50 in the state shown in Figure 3 by rotating the nozzle 70 of the content sprayer 50 relative to the nozzle joint 80. When the content sprayer 50 is in the state shown in Figure 3, the protrusion 85 of the nozzle joint 80 fits into the groove 71a of the first cylindrical portion 71 of the nozzle 70, so the nozzle 70 does not rotate easily relative to the nozzle joint 80.
[0060] When the content ejection device 50 is in the state shown in Figure 3, the user can, for example, hold the gripping portion 41a of the first part 41 of the handle 40 with the second, third, fourth and fifth fingers of the right or left hand, and operate the operating portion 42b of the second part 42 of the handle 40 with the first finger of the hand that is holding the gripping portion 41a of the first part 41 of the user's right or left hand, thereby changing the pump-type product 10 from a state in which the handle 40 is open as shown in Figure 1(a) to a state in which the handle 40 is closed as shown in Figure 1(b). When the user changes the handle 40 of the pump-type product 10 to the closed state as shown in Figure 1(b), the protrusion 42c of the second part 42 of the handle 40 pushes the content spraying device 50 through the plate-like part 62 of the L-shaped pipe member 60, and the pump mounting part 61 of the L-shaped pipe member 60 of the content spraying device 50 pushes the moving part 32 of the pump 30 against the fixed part 31 of the pump 30, causing the contents inside the container 20 to be expelled outside the container 20 by the pump 30.
[0061] The contents discharged from the container 20 by the pump 30 pass through the interior of the L-shaped pipe member 60 of the content-spraying device 50, and then pass from a flow path 86 of the nozzle joint 80 through the groove 73a of the third cylindrical portion 73 of the nozzle 70 and the wide-angle mist spray groove 84b of the fourth cylindrical portion 84 of the nozzle joint 80 to be introduced into a first inlet path 51b of the mechanical breakup mechanism 51, and also pass from a flow path 87 of the nozzle joint 80 through the groove 74a of the fourth cylindrical portion 74 of the nozzle 70 and the wide-angle mist spray groove 84c of the fourth cylindrical portion 84 of the nozzle joint 80 to be introduced into a second inlet path 51c of the mechanical breakup mechanism 51. The contents introduced into the first inlet path 51b of the mechanical breakup mechanism 51 are then introduced into the swirl chamber 51a of the mechanical breakup mechanism 51 from the first inlet path 51b. The contents introduced into the second introduction passage 51c of the mechanical breakup mechanism 51 are introduced from the second introduction passage 51c into the swirling chamber 51a of the mechanical breakup mechanism 51. Therefore, the contents introduced into the swirling chamber 51a via the first introduction passage 51b and the second introduction passage 51c swirl within the swirling chamber 51a and are sprayed in the form of a mist from the orifice 70a.
[0062] Next, the operation of the pump-type product 10 in the narrow-angle mist spray mode will be described.
[0063] The user can place the content sprayer 50 in the state shown in Figure 4 by rotating the nozzle 70 of the content sprayer 50 relative to the nozzle joint 80. When the content sprayer 50 is in the state shown in Figure 4, the protrusion 85 of the nozzle joint 80 fits into the groove 71a of the first cylindrical portion 71 of the nozzle 70, so the nozzle 70 does not rotate easily relative to the nozzle joint 80.
[0064] When the content ejection device 50 is in the state shown in Figure 4, the user can, for example, hold the gripping portion 41a of the first part 41 of the handle 40 with the second, third, fourth and fifth fingers of the right or left hand, and operate the operating portion 42b of the second part 42 of the handle 40 with the first finger of the hand that is holding the gripping portion 41a of the first part 41 of the user's right or left hand, thereby changing the pump-type product 10 from a state in which the handle 40 is open as shown in Figure 1(a) to a state in which the handle 40 is closed as shown in Figure 1(b). When the user changes the handle 40 of the pump-type product 10 to the closed state as shown in Figure 1(b), the protrusion 42c of the second part 42 of the handle 40 pushes the content spraying device 50 through the plate-like part 62 of the L-shaped pipe member 60, and the pump mounting part 61 of the L-shaped pipe member 60 of the content spraying device 50 pushes the moving part 32 of the pump 30 against the fixed part 31 of the pump 30, causing the contents inside the container 20 to be expelled outside the container 20 by the pump 30.
[0065] The contents discharged from the container 20 by the pump 30 pass through the interior of the L-shaped pipe member 60 of the content-spraying device 50, and then pass through a flow path 86 of the nozzle joint 80, the groove 73a of the third cylindrical portion 73 of the nozzle 70, the narrow-angle mist spray groove 84d of the fourth cylindrical portion 84 of the nozzle joint 80, and then into a first inlet path 52b of the mechanical breakup mechanism 52. At the same time, the contents pass through a flow path 87 of the nozzle joint 80, the groove 74a of the fourth cylindrical portion 74 of the nozzle 70, and the narrow-angle mist spray groove 84e of the fourth cylindrical portion 84 of the nozzle joint 80, and then into a second inlet path 52c of the mechanical breakup mechanism 52. The contents introduced into the first inlet path 52b of the mechanical breakup mechanism 52 are introduced into the swirl chamber 52a of the mechanical breakup mechanism 52 from the first inlet path 52b. The contents introduced into the second inlet passage 52c of the mechanical breakup mechanism 52 are introduced from the second inlet passage 52c into the swirling chamber 52a of the mechanical breakup mechanism 52. Therefore, the contents introduced into the swirling chamber 52a via the first inlet passage 52b and the second inlet passage 52c swirl within the swirling chamber 52a and are sprayed in the form of a mist from the orifice 70a.
[0066] As described above, the flow path formed by the narrow-angle mist spray groove 84d of the fourth cylindrical portion 84 of the nozzle joint 80 and the inner circumferential surface of the third cylindrical portion 73 of the nozzle 70 is narrower than the flow path formed by the wide-angle mist spray groove 84b of the fourth cylindrical portion 84 of the nozzle joint 80 and the inner circumferential surface of the third cylindrical portion 73 of the nozzle 70, and the flow path formed by the narrow-angle mist spray groove 84e of the fourth cylindrical portion 84 of the nozzle joint 80 and the outer circumferential surface of the fourth cylindrical portion 74 of the nozzle 70 is narrower than the flow path formed by the wide-angle mist spray groove 84c of the fourth cylindrical portion 84 of the nozzle joint 80 and the outer circumferential surface of the fourth cylindrical portion 74 of the nozzle 70. Therefore, the flow rate of the contents introduced into the swirl chamber 52a of the mechanical breakup mechanism 52 is smaller than the flow rate of the contents introduced into the swirl chamber 51a of the mechanical breakup mechanism 51. Therefore, when the content-spraying device 50 is in the state shown in Figure 4, the spray range of the contents sprayed in mist form from the orifice 70a is narrower than the spray range of the contents sprayed in mist form from the orifice 70a when the content-spraying device 50 is in the state shown in Figure 3.
[0067] Next, the operation of the pump-type product 10 in the stop spray mode will be described.
[0068] The user can place the content sprayer 50 in the state shown in Figure 5 by rotating the nozzle 70 of the content sprayer 50 relative to the nozzle joint 80. When the content sprayer 50 is in the state shown in Figure 5, the protrusion 85 of the nozzle joint 80 fits into the groove 71a of the first cylindrical portion 71 of the nozzle 70, so the nozzle 70 does not rotate easily relative to the nozzle joint 80.
[0069] 5, the groove 73a of the third cylindrical portion 73 of the nozzle 70 does not communicate with the first introduction passage groove 70c of the nozzle 70, and the groove 74a of the fourth cylindrical portion 74 of the nozzle 70 does not communicate with the second introduction passage groove 70d of the nozzle 70. In other words, the flow path is closed in the content-ejecting device 50. Therefore, for example, even if a user holds the gripping portion 41a of the first part 41 of the handle 40 with the second, third, fourth and fifth fingers of their right or left hand, and operates the operating portion 42b of the second part 42 of the handle 40 with the first finger of the hand that is holding the gripping portion 41a of the first part 41 of the user's right or left hand, the pump-type product 10 will not spray the contents from the orifice 70a, and the handle 40 will not change from the open state shown in Figure 1(a) to the closed state shown in Figure 1(b).
[0070] As described above, the content sprayer 50 can be formed with a plurality of mechanical breakup mechanisms 51 each having an orifice 70a for spraying the content of the pump-type product 10, and can therefore spray the content in mist form from the plurality of orifices 70a. Similarly, the content sprayer 50 can be formed with a plurality of mechanical breakup mechanisms 52 each having an orifice 70a for spraying the content of the pump-type product 10, and can therefore spray the content in mist form from the plurality of orifices 70a.
[0071] In the contents injection device 50, in each of the multiple mechanical breakup mechanisms 51, of the first inlet passage 51b and the second inlet passage 51c for introducing the contents into the swirling chamber 51a, the contents are introduced into the first inlet passage 51b from the side opposite the center of the fourth cylindrical portion 84 of the nozzle joint 80, and the contents are introduced into the second inlet passage 51c from the center of the fourth cylindrical portion 84 with respect to the injection protrusion, so that the size of each of the multiple mechanical breakup mechanisms 51 in the circumferential direction can be reduced. Similarly, in each of the multiple mechanical breakup mechanisms 52, the contents injection device 50 has a first inlet passage 52b and a second inlet passage 52c for introducing contents into the swirling chamber 52a, and the contents are introduced into the first inlet passage 52b from the side opposite the center of the fourth cylindrical portion 84 of the nozzle joint 80, and the contents are introduced into the second inlet passage 52c from the center of the fourth cylindrical portion 84 with respect to the injection protrusion, so that the size of each of the multiple mechanical breakup mechanisms 52 in the circumferential direction can be reduced.
[0072] In the content injection device 50, the swirl chamber groove 70b for forming the swirl chamber 51a of the mechanical breakup mechanism 51 or the swirl chamber 52a of the mechanical breakup mechanism 52, the first introduction passage groove 70c for forming the first introduction passage 51b of the mechanical breakup mechanism 51 or the first introduction passage 52b of the mechanical breakup mechanism 52, and the second introduction passage groove 70d for forming the second introduction passage 51c of the mechanical breakup mechanism 51 or the second introduction passage 52c of the mechanical breakup mechanism 52 are formed only in the nozzle 70 out of the nozzle 70 and the fourth cylindrical portion 84 of the nozzle joint 80, so the accuracy required for circumferential alignment of the nozzle 70 and the fourth cylindrical portion 84 of the nozzle joint 80 can be reduced.
[0073] (Second embodiment) First, the configuration of a pump type product according to the second embodiment of the present invention will be described.
[0074] Among the components of the pump-type product of this embodiment, those that are similar to the components of the pump-type product 10 of 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.
[0075] Fig. 11(a) is a front view of a content spraying device 150 for a pump-type product according to this embodiment when spraying the content straight. Fig. 11(b) is a cross-sectional view taken along the line DD in Fig. 11(a).
[0076] The configuration of the pump type product according to this embodiment is the same as that of the pump type product 10, except that the content spraying device 150 shown in FIG. 11 is replaced with the content spraying device 50 (see FIGS. 1 to 5).
[0077] FIG. 12 is a front view of a nozzle joint 180 of a pump-type product according to this embodiment.
[0078] The configuration of the content spraying device 150 is the same as the configuration of the content spraying device 50, except that the nozzle joint 180 shown in FIG. 12 is replaced with the nozzle joint 80 (see FIGS. 9 and 10).
[0079] The configuration of the nozzle joint 180 is the same as that of the nozzle joint 80, except that a fourth cylindrical portion 184 as the annular protrusion of the present invention is provided instead of the fourth cylindrical portion 84 (see FIGS. 9 and 10).
[0080] The configuration of the fourth cylindrical portion 184 is the same as that of the fourth cylindrical portion 84, except that when the content spray mode is a straight spray mode in which the content is sprayed straight from the orifice 70a, the fourth cylindrical portion 84 is provided with a straight spray groove 185 for introducing the content into the swirl chamber groove 70b of the nozzle 70 instead of the mist narrow-angle spray groove 84d (see Figure 9) and the mist narrow-angle spray groove 84e (see Figure 9).
[0081] Three straight injection grooves 185 are formed at equal intervals on the circumference of the same circle in the fourth cylindrical portion 184. The straight injection groove 185 has a portion 185a formed on the outer peripheral surface of the fourth cylindrical portion 184 to connect the groove 73a of the third cylindrical portion 73 of the nozzle 70 and the first introduction passage groove 70c of the nozzle 70. The straight injection groove 185 has a portion 185b formed on the inner peripheral surface of the fourth cylindrical portion 184 to connect the groove 74a of the fourth cylindrical portion 74 of the nozzle 70 and the second introduction passage groove 70d of the nozzle 70. The straight injection groove 185 has a portion 185c formed on the end portion 84a of the fourth cylindrical portion 184 to connect the portion 185a, the portion 185b, and the swirl chamber groove 70b.
[0082] Next, the operation of the pump type product according to this embodiment will be described.
[0083] The content spraying device 150 can switch the content spraying mode by rotating the nozzle 70 relative to the fourth cylindrical portion 184 of the nozzle joint 180. The content spraying modes include a wide-angle mist spray mode, a straight spray mode, and a spray stop mode.
[0084] First, the operation of the pump-type product of this embodiment in the mist wide-angle spray mode and the operation of the pump-type product of this embodiment in the spray stop mode are similar to the operation of pump-type product 10 in the mist wide-angle spray mode and the operation of pump-type product 10 in the spray stop mode, respectively.
[0085] Next, the operation of the pump type product according to this embodiment in the straight injection mode will be described.
[0086] The user can place the content sprayer 150 in the state shown in Figure 11 by rotating the nozzle 70 of the content sprayer 150 relative to the nozzle joint 180. When the content sprayer 150 is in the state shown in Figure 11, the protrusion 85 of the nozzle joint 180 fits into the groove 71a of the first cylindrical portion 71 of the nozzle 70, so the nozzle 70 does not rotate easily relative to the nozzle joint 180.
[0087] When the content ejection device 150 is in the state shown in Figure 11, the user can, for example, hold the gripping portion 41a of the first part 41 of the handle 40 with the second, third, fourth and fifth fingers of the right or left hand, and operate the operating portion 42b of the second part 42 of the handle 40 with the first finger of the hand that is holding the gripping portion 41a of the first part 41 of the user's right or left hand, thereby changing the pump-type product of this embodiment from a state in which the handle 40 is open as shown in Figure 1(a) to a state in which the handle 40 is closed as shown in Figure 1(b). In the pump-type product of this embodiment, when the user changes the handle 40 to the closed state as shown in Figure 1(b), the protrusion 42c of the second part 42 of the handle 40 pushes the content spraying device 150 through the plate-like part 62 of the L-shaped pipe member 60, and the pump mounting part 61 of the L-shaped pipe member 60 of the content spraying device 150 pushes the moving part 32 of the pump 30 against the fixed part 31 of the pump 30, so that the contents inside the container 20 are expelled outside the container 20 by the pump 30.
[0088] The contents discharged from the container 20 by the pump 30 pass through the interior of the L-shaped pipe member 60 of the content-spraying device 150, and then are introduced from the flow path 86 of the nozzle joint 180 through the groove 73a of the third cylindrical portion 73 of the nozzle 70 into the straight spray groove 185 of the fourth cylindrical portion 185 of the nozzle joint 180, and also from the flow path 87 of the nozzle joint 180 through the groove 74a of the fourth cylindrical portion 74 of the nozzle 70 into the straight spray groove 185 of the fourth cylindrical portion 184 of the nozzle joint 180. Therefore, the contents introduced into the straight spray groove 185 of the fourth cylindrical portion 184 of the nozzle joint 180 are sprayed straight from the orifice 70a.
[0089] As described above, the content spraying device 150 has a straight spray groove 185 formed in the fourth cylindrical portion 184 of the nozzle joint 180, so that the content spraying mode can be switched between a mode in which the content is sprayed in a mist form from the orifice 70a and a straight spray mode by rotating the nozzle 70 relative to the fourth cylindrical portion 184 of the nozzle joint 180.
[0090] (Third embodiment) First, the configuration of a pump type product according to the third embodiment of the present invention will be described.
[0091] Among the components of the pump-type product of this embodiment, those components that are similar to the components of the pump-type product of the second embodiment are given the same symbols as the components of the pump-type product of the second embodiment, and detailed explanations are omitted.
[0092] Fig. 13(a) is a front view of a content spraying device 250 for a pump type product according to this embodiment when spraying the content straight. Fig. 13(b) is a cross-sectional view taken along the line EE in Fig. 13(a).
[0093] The configuration of the pump-type product of this embodiment is the same as the configuration of the pump-type product of the second embodiment, except that the content spraying device 250 shown in Figure 13 is replaced with content spraying device 150 (see Figure 11).
[0094] FIG. 14 is a front view of a nozzle joint 280 of a pump-type product according to this embodiment.
[0095] The configuration of the content ejection device 250 is the same as the configuration of the content ejection device 150, except that the nozzle joint 280 shown in FIG. 14 is provided instead of the nozzle joint 180 (see FIG. 12).
[0096] The configuration of the nozzle joint 280 is the same as that of the nozzle joint 180, except that a fourth cylindrical portion 284 as the annular protrusion of the present invention is provided instead of the fourth cylindrical portion 184 (see FIG. 12).
[0097] The configuration of the fourth cylindrical portion 284 is similar to that of the fourth cylindrical portion 184, except that the fourth cylindrical portion 184 is provided with a straight injection groove 285 for introducing the contents into the swirling chamber groove 70b of the nozzle 70 when the contents injection mode is the straight injection mode, instead of the straight injection groove 185 (see Figure 12).
[0098] Three straight injection grooves 285 are formed at equal intervals on the circumference of the same circle in the fourth cylindrical portion 284. The straight injection groove 285 has a portion 285a formed on the inner circumferential surface of the fourth cylindrical portion 284 to connect the groove 74a of the fourth cylindrical portion 74 of the nozzle 70 and the second introduction passage groove 70d of the nozzle 70. The straight injection groove 285 has a portion 285b formed on the end portion 84a of the fourth cylindrical portion 284 to connect the portion 285a with the swirl chamber groove 70b.
[0099] Next, the operation of the pump type product according to this embodiment will be described.
[0100] The content spraying device 250 can switch the content spraying mode by rotating the nozzle 70 relative to the fourth cylindrical portion 284 of the nozzle joint 280. The content spraying modes include a wide-angle mist spray mode, a straight spray mode, and a stop spray mode.
[0101] First, the operation of the pump-type product of this embodiment in the mist wide-angle spray mode and the operation of the pump-type product of this embodiment in the spray stop mode are similar to the operation of the pump-type product of the second embodiment in the mist wide-angle spray mode and the operation of the pump-type product of the second embodiment in the spray stop mode, respectively.
[0102] Next, the operation of the pump type product according to this embodiment in the straight injection mode will be described.
[0103] The user can place the content sprayer 250 in the state shown in Figure 13 by rotating the nozzle 70 of the content sprayer 250 relative to the nozzle joint 280. When the content sprayer 250 is in the state shown in Figure 13, the protrusion 85 of the nozzle joint 280 fits into the groove 71a of the first cylindrical portion 71 of the nozzle 70, so the nozzle 70 does not rotate easily relative to the nozzle joint 280.
[0104] When the content ejection device 250 is in the state shown in Figure 13, the user can, for example, hold the gripping portion 41a of the first part 41 of the handle 40 with the second, third, fourth and fifth fingers of the right or left hand, and operate the operating portion 42b of the second part 42 of the handle 40 with the first finger of the hand that is holding the gripping portion 41a of the first part 41 of the user's right or left hand, thereby changing the pump-type product of this embodiment from a state in which the handle 40 is open as shown in Figure 1(a) to a state in which the handle 40 is closed as shown in Figure 1(b). In the pump-type product of this embodiment, when the user changes the handle 40 to the closed state as shown in Figure 1(b), the protrusion 42c of the second part 42 of the handle 40 pushes the content spraying device 250 through the plate-like part 62 of the L-shaped pipe member 60, and the pump mounting part 61 of the L-shaped pipe member 60 of the content spraying device 250 pushes the moving part 32 of the pump 30 against the fixed part 31 of the pump 30, so that the contents inside the container 20 are expelled outside the container 20 by the pump 30.
[0105] The contents discharged from the container 20 by the pump 30 pass through the inside of the L-shaped pipe member 60 of the content-spraying device 250, and then are introduced from the flow path 87 of the nozzle joint 280 through the groove 74a of the fourth cylindrical portion 74 of the nozzle 70 into the straight spray groove 285 of the fourth cylindrical portion 284 of the nozzle joint 280. Therefore, the contents introduced into the straight spray groove 285 of the fourth cylindrical portion 284 of the nozzle joint 280 are sprayed straight from the orifice 70a.
[0106] As described above, in the content spraying device 250, the straight spray groove 285 is formed only on the inner peripheral surface of the outer peripheral surface and inner peripheral surface of the fourth cylindrical portion 284. That is, in the content spraying device 250, the straight spray groove 285 is formed on the side opposite the center side of the fourth cylindrical portion 284 with respect to the fourth cylindrical portion 284, and on the center side of the fourth cylindrical portion 284, and the content is introduced only from the center side of the fourth cylindrical portion 284. Therefore, compared to the content spraying device 150 according to the second embodiment in which the straight spray groove 185 is formed on the side opposite the center side of the fourth cylindrical portion 184 with respect to the fourth cylindrical portion 184 with respect to the fourth cylindrical portion 184, and the content is introduced from the center side of the fourth cylindrical portion 184, the content spraying device 250 can simplify the structure of the flow path of the content when the content is sprayed straight from the orifice 70a.
[0107] In the content spraying device 250, the straight spray groove 285 is introduced from only the center side of the fourth cylindrical portion 284, out of the side opposite the center side of the fourth cylindrical portion 284 and the center side of the fourth cylindrical portion 284. Therefore, unlike the content spraying device 150 according to the second embodiment in which the straight spray groove 185 is introduced from the side opposite the center side of the fourth cylindrical portion 184 and the center side of the fourth cylindrical portion 184, when the content is sprayed straight from the orifice 70a, the flow of the content in the swirl chamber groove 70b of the nozzle 70 is one-way. Therefore, when the content is sprayed straight from the orifice 70a, the content spraying device 250 can spray the content from the orifice 70a more straightly than the content spraying device 150 according to the second embodiment.
[0108] In the content spraying device 250, the straight spray groove 285 is introduced from only the center side of the fourth cylindrical portion 284, out of the side opposite the center side of the fourth cylindrical portion 284 and the center side of the fourth cylindrical portion 284, so the range where airtightness is required between the nozzle 70 and the fourth cylindrical portion of the nozzle joint is smaller compared to the content spraying device 150 according to the second embodiment, in which the straight spray groove 185 is introduced from the side opposite the center side of the fourth cylindrical portion 184 and the center side of the fourth cylindrical portion 184. Therefore, the content spraying device 250 can improve airtightness compared to the content spraying device 150 according to the second embodiment.
[0109] (Fourth embodiment) First, the configuration of a pump type product according to the fourth embodiment of the present invention will be described.
[0110] Among the components of the pump-type product of this embodiment, those components that are similar to the components of the pump-type product of the second embodiment are given the same symbols as the components of the pump-type product of the second embodiment, and detailed explanations are omitted.
[0111] Fig. 15(a) is a front view of a content spraying device 350 for a pump type product according to this embodiment when spraying the content straight. Fig. 15(b) is a cross-sectional view taken along the line FF in Fig. 15(a).
[0112] The configuration of the pump-type product of this embodiment is the same as the configuration of the pump-type product of the second embodiment, except that the content spraying device 350 shown in Figure 15 is replaced with the content spraying device 150 (see Figure 11).
[0113] FIG. 16 is a front view of a nozzle joint 380 of a pump-type product according to this embodiment.
[0114] The configuration of the content ejection device 350 is the same as the configuration of the content ejection device 150, except that the nozzle joint 380 shown in FIG. 16 is provided instead of the nozzle joint 180 (see FIG. 12).
[0115] The configuration of the nozzle joint 380 is similar to that of the nozzle joint 180, except that a fourth cylindrical portion 384 serving as the annular protrusion of the present invention is provided in place of the fourth cylindrical portion 184 (see FIG. 12).
[0116] The configuration of the fourth cylindrical portion 384 is similar to that of the fourth cylindrical portion 184, except that the fourth cylindrical portion 184 is provided with a straight injection groove 385 for introducing the contents into the swirling chamber groove 70b of the nozzle 70 when the contents injection mode is the straight injection mode, instead of the straight injection groove 185 (see Figure 12).
[0117] Three straight injection grooves 385 are formed at equal intervals on the circumference of the same circle in the fourth cylindrical portion 384. The straight injection groove 385 has a portion 385a formed on the outer peripheral surface of the fourth cylindrical portion 384 to connect the groove 73a of the third cylindrical portion 73 of the nozzle 70 and the first introduction passage groove 70c of the nozzle 70. The straight injection groove 385 has a portion 385b formed on the end portion 84a of the fourth cylindrical portion 384 to connect the portion 385a with the swirl chamber groove 70b.
[0118] Next, the operation of the pump type product according to this embodiment will be described.
[0119] The content spraying device 350 can switch the content spraying mode by rotating the nozzle 70 relative to the fourth cylindrical portion 384 of the nozzle joint 380. The content spraying modes include a wide-angle mist spray mode, a straight spray mode, and a stop spray mode.
[0120] First, the operation of the pump-type product of this embodiment in the mist wide-angle spray mode and the operation of the pump-type product of this embodiment in the spray stop mode are similar to the operation of the pump-type product of the second embodiment in the mist wide-angle spray mode and the operation of the pump-type product of the second embodiment in the spray stop mode, respectively.
[0121] Next, the operation of the pump type product according to this embodiment in the straight injection mode will be described.
[0122] The user can place the content sprayer 350 in the state shown in Figure 15 by rotating the nozzle 70 of the content sprayer 350 relative to the nozzle joint 380. When the content sprayer 350 is in the state shown in Figure 15, the protrusion 85 of the nozzle joint 380 fits into the groove 71a of the first cylindrical portion 71 of the nozzle 70, so the nozzle 70 does not rotate easily relative to the nozzle joint 380.
[0123] When the content ejection device 350 is in the state shown in Figure 15, the user can, for example, hold the gripping portion 41a of the first part 41 of the handle 40 with the second, third, fourth and fifth fingers of the right or left hand, and operate the operating portion 42b of the second part 42 of the handle 40 with the first finger of the hand that is holding the gripping portion 41a of the first part 41 of the user's right or left hand, thereby changing the pump-type product of this embodiment from a state in which the handle 40 is open as shown in Figure 1(a) to a state in which the handle 40 is closed as shown in Figure 1(b). In the pump-type product of this embodiment, when the user changes the handle 40 to the closed state as shown in Figure 1(b), the protrusion 42c of the second part 42 of the handle 40 pushes the content spraying device 350 through the plate-like part 62 of the L-shaped pipe member 60, and the pump mounting part 61 of the L-shaped pipe member 60 of the content spraying device 350 pushes the moving part 32 of the pump 30 against the fixed part 31 of the pump 30, so that the contents inside the container 20 are expelled outside the container 20 by the pump 30.
[0124] The contents discharged from the container 20 by the pump 30 pass through the inside of the L-shaped pipe member 60 of the content-spraying device 350, and then are introduced from the flow path 86 of the nozzle joint 380 through the groove 73a of the third cylindrical portion 73 of the nozzle 70 into the straight spray groove 385 of the fourth cylindrical portion 384 of the nozzle joint 380. Therefore, the contents introduced into the straight spray groove 385 of the fourth cylindrical portion 384 of the nozzle joint 380 are sprayed straight from the orifice 70a.
[0125] As described above, in the content spraying device 350, the straight spray groove 385 is formed only on the outer peripheral surface of the inner and outer peripheral surfaces of the fourth cylindrical portion 384. That is, in the content spraying device 350, the straight spray groove 385 is formed on the fourth cylindrical portion 384 only on the side opposite the center of the fourth cylindrical portion 384, between the side opposite the center of the fourth cylindrical portion 384 and the center of the fourth cylindrical portion 384. Therefore, compared to the content spraying device 150 according to the second embodiment in which the straight spray groove 185 is formed on the fourth cylindrical portion 184 and the side opposite the center of the fourth cylindrical portion 184, the content spraying device 350 can simplify the structure of the flow path of the content when the content is sprayed straight from the orifice 70a.
[0126] In the content spraying device 350, the straight spray groove 385 is introduced into the fourth cylindrical portion 384 from only the side opposite the center of the fourth cylindrical portion 384, out of the side opposite the center of the fourth cylindrical portion 384 and the center of the fourth cylindrical portion 384. Therefore, unlike the content spraying device 150 according to the second embodiment in which the straight spray groove 185 is introduced into the fourth cylindrical portion 184 from the side opposite the center of the fourth cylindrical portion 184 and the center of the fourth cylindrical portion 184, when the content is sprayed straight from the orifice 70a, the flow of the content in the swirl chamber groove 70b of the nozzle 70 is one-way. Therefore, when the content is sprayed straight from the orifice 70a, the content spraying device 350 can spray the content from the orifice 70a more straightly than the content spraying device 150 according to the second embodiment.
[0127] In the content spraying device 350, the straight spray groove 385 is introduced into the fourth cylindrical portion 384 from only the side opposite the center of the fourth cylindrical portion 384, out of the side opposite the center of the fourth cylindrical portion 384 and the center of the fourth cylindrical portion 384. Therefore, compared to the content spraying device 150 according to the second embodiment in which the straight spray groove 185 is introduced into the fourth cylindrical portion 184 from the side opposite the center of the fourth cylindrical portion 184 and the center of the fourth cylindrical portion 184, the range in which airtightness is required between the nozzle 70 and the fourth cylindrical portion of the nozzle joint is smaller. Therefore, the content spraying device 350 can improve airtightness compared to the content spraying device 150 according to the second embodiment.
[0128] In the content spraying device 350, the straight spray groove 385 is introduced only from the side opposite the center of the fourth cylindrical portion 384, between the side opposite the center of the fourth cylindrical portion 384 and the center of the fourth cylindrical portion 384. Therefore, compared to the content spraying device 250 according to the third embodiment, in which the straight spray groove 285 is introduced only from the side opposite the center of the fourth cylindrical portion 284 and the center of the fourth cylindrical portion 284, the mist wide-angle spray groove and the straight spray groove are farther apart in the fourth cylindrical portion of the nozzle joint. Therefore, the content spraying device 350 can improve airtightness compared to the content spraying device 250 according to the third embodiment.
[0129] (Fifth embodiment) First, the configuration of a pump type product according to the fifth embodiment of the present invention will be described.
[0130] Among the components of the pump-type product of this embodiment, those that are similar to the components of the pump-type product 10 of 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.
[0131] FIG. 17(a) is a front view of a content spraying device 450 of a pump-type product according to this embodiment, which includes a mechanical breakup mechanism 451 that sprays the contents in a mist-like manner at a wide angle. FIG. 17(b) is a cross-sectional view taken along the arrow GG in FIG. 17(a). FIG. 18(a) is a front view of a content spraying device 450, which includes a mechanical breakup mechanism 452 that sprays the contents in a mist-like manner at a narrow angle. FIG. 18(b) is a cross-sectional view taken along the arrow HH in FIG. 18(a). FIG. 19(a) is a front view of a content spraying device 450, which does not include a mechanical breakup mechanism. FIG. 19(b) is a cross-sectional view taken along the arrow II in FIG. 19(a).
[0132] The configuration of the pump type product according to this embodiment is the same as that of the pump type product 10, except that the content spraying device 450 shown in Figures 17 to 19 is replaced with the content spraying device 50 (see Figures 1 to 5).
[0133] Figure 20 is a rear view of a nozzle 470 of a pump type product according to this embodiment. Figure 21 is a front view of a nozzle joint 480 of a pump type product according to this embodiment.
[0134] The configuration of the content ejection device 450 is similar to that of the content ejection device 50, except that the nozzle 470 shown in Figure 20 and the nozzle joint 480 shown in Figure 21 are replaced with the nozzle 70 (see Figures 7 and 8) and the nozzle joint 80 (see Figures 9 and 10).
[0135] 17, content spraying device 450 can have three mechanical breakup mechanisms 451 formed at equal intervals on the circumference of the same circle for applying a swirling force to the contents near orifice 70a of nozzle 470 to spray the contents in mist form from orifice 70a. Each of the three mechanical breakup mechanisms 451 includes orifice 70a, a swirling chamber 451a in which the contents swirl, and a first introduction path 451b and a second introduction path 451c for introducing the contents into swirling chamber 451a so that the contents swirl in swirling chamber 451a.
[0136] 18, content spraying device 450 can have three mechanical breakup mechanisms 452 formed at equal intervals on the same circle for applying a swirling force to the contents near orifice 70a of nozzle 470 to spray the contents in a mist form from orifice 70a. Mechanical breakup mechanism 452 is a mechanism for spraying the contents at a narrower angle than mechanical breakup mechanism 451. Each of the three mechanical breakup mechanisms 452 includes orifice 70a, a swirling chamber 452a in which the contents swirl, and a first introduction path 452b and a second introduction path 452c for introducing the contents into swirling chamber 452a so that the contents swirl in swirling chamber 452a.
[0137] As shown in Figure 20, the configuration of nozzle 470 is the same as that of nozzle 70 in which the groove for the swirling chamber 70b (see Figures 7 and 8), the groove for the first introduction path 70c (see Figures 7 and 8), and the groove for the second introduction path 70d (see Figures 7 and 8) are not provided.
[0138] As shown in Figure 21, the configuration of nozzle joint 480 is similar to that of nozzle joint 80, except that a fourth cylindrical portion 484 as the annular protrusion of the present invention is replaced with a fourth cylindrical portion 84 (see Figures 9 and 10).
[0139] The configuration of fourth cylindrical portion 484 is such that fourth cylindrical portion 84 is provided with mist wide-angle injection groove 484b, mist wide-angle injection groove 484c, mist narrow-angle injection groove 484d, and mist narrow-angle injection groove 484e instead of mist wide-angle injection groove 84b, mist wide-angle injection groove 84c, mist narrow-angle injection groove 84d, and mist narrow-angle injection groove 84e (see FIGS. 9 and 10). Fourth cylindrical portion 484 is provided with swirl chamber groove 480a for forming swirl chamber 451a of mechanical breakup mechanism 451 together with nozzle 470, and first introduction path groove 480b for forming first introduction path 451b of mechanical breakup mechanism 451 together with nozzle 470. 80b, a second inlet passage groove 480c for forming the second inlet passage 451c of the mechanical breakup mechanism 451 together with the nozzle 470, a swirl chamber groove 480d for forming the swirl chamber 452a of the mechanical breakup mechanism 452 together with the nozzle 470, a first inlet passage groove 480e for forming the first inlet passage 452b of the mechanical breakup mechanism 452 together with the nozzle 470, and a second inlet passage groove 480f for forming the second inlet passage 452c of the mechanical breakup mechanism 452 together with the nozzle 470.
[0140] Three wide-angle mist injection grooves 484b are formed at equal intervals on the circumference of the same circle on the outer circumferential surface of the fourth cylindrical portion 484 to connect the groove 73a of the third cylindrical portion 73 of the nozzle 470 with the first introduction passage 451b of the mechanical breakup mechanism 451. Three wide-angle mist injection grooves 484c are formed at equal intervals on the circumference of the same circle on the inner circumferential surface of the fourth cylindrical portion 484 to connect the groove 74a of the fourth cylindrical portion 74 of the nozzle 470 with the second introduction passage 451c of the mechanical breakup mechanism 451. Three narrow-angle mist injection grooves 484d are formed at equal intervals on the circumference of the same circle on the outer circumferential surface of the fourth cylindrical portion 484 to connect the groove 73a of the third cylindrical portion 73 of the nozzle 470 with the first introduction passage 452b of the mechanical breakup mechanism 452. Three narrow-angle mist injection grooves 484e are formed at equal intervals on the inner surface of the fourth cylindrical portion 484 to connect the groove 74a of the fourth cylindrical portion 74 of the nozzle 470 to the second introduction passage 452c of the mechanical breakup mechanism 452.
[0141] Wide-angle mist injection groove 484b and narrow-angle mist injection groove 484d have approximately the same width in the circumferential direction of fourth cylindrical portion 484 and the same depth in the radial direction of fourth cylindrical portion 484. In other words, the flow path formed by wide-angle mist injection groove 484b of fourth cylindrical portion 484 of nozzle joint 480 and the inner circumferential surface of third cylindrical portion 73 of nozzle 470, and the flow path formed by narrow-angle mist injection groove 484d of fourth cylindrical portion 484 of nozzle joint 480 and the inner circumferential surface of third cylindrical portion 73 of nozzle 470 have approximately the same width. Similarly, wide-angle mist injection groove 484c and narrow-angle mist injection groove 484e have approximately the same width in the circumferential direction of fourth cylindrical portion 484 and the same depth in the radial direction of fourth cylindrical portion 484. That is, the flow path formed by the groove 484c for wide-angle mist injection of the fourth cylindrical portion 484 of the nozzle joint 480 and the outer peripheral surface of the fourth cylindrical portion 74 of the nozzle 470 and the flow path formed by the groove 484e for narrow-angle mist injection of the fourth cylindrical portion 484 of the nozzle joint 480 and the outer peripheral surface of the fourth cylindrical portion 74 of the nozzle 470 are of approximately the same width.
[0142] Swirling chamber groove 480d is deeper than swirl chamber groove 480a. First introduction path groove 480e is wider and deeper in the circumferential direction of fourth cylindrical portion 484 than first introduction path groove 480b. Similarly, second introduction path groove 480f is wider and deeper in the circumferential direction of fourth cylindrical portion 484 than second introduction path groove 480c.
[0143] Next, the operation of the pump type product according to this embodiment will be described.
[0144] The content spraying device 450 can switch the content spraying mode by rotating the nozzle 470 relative to the fourth cylindrical portion 484 of the nozzle joint 480. The content spraying modes include a wide-angle mist spray mode as the first mist spray mode of the present invention, a narrow-angle mist spray mode as the second mist spray mode of the present invention, and a spray stop mode.
[0145] First, the operation of the pump type product according to this embodiment in the wide-angle mist spray mode will be described.
[0146] The user can place the content sprayer 450 in the state shown in Fig. 17 by rotating the nozzle 470 of the content sprayer 450 relative to the nozzle joint 480. When the content sprayer 450 is in the state shown in Fig. 17, the protrusion 85 of the nozzle joint 480 fits into the groove 71a of the first cylindrical portion 71 of the nozzle 470, so the nozzle 470 does not rotate easily relative to the nozzle joint 480.
[0147] When the content ejection device 450 is in the state shown in Figure 17, the user can, for example, hold the gripping portion 41a of the first part 41 of the handle 40 with the second, third, fourth and fifth fingers of the right or left hand, and operate the operating portion 42b of the second part 42 of the handle 40 with the first finger of the hand that is holding the gripping portion 41a of the first part 41 of the user's right or left hand, thereby changing the pump-type product of this embodiment from a state in which the handle 40 is open as shown in Figure 1(a) to a state in which the handle 40 is closed as shown in Figure 1(b). In the pump-type product of this embodiment, when the user changes the handle 40 to the closed state as shown in Figure 1(b), the protrusion 42c of the second part 42 of the handle 40 pushes the content spraying device 450 through the plate-like part 62 of the L-shaped pipe member 60, and the pump mounting part 61 of the L-shaped pipe member 60 of the content spraying device 450 pushes the moving part 32 of the pump 30 against the fixed part 31 of the pump 30, so that the contents inside the container 20 are expelled outside the container 20 by the pump 30.
[0148] The contents discharged from the container 20 by the pump 30 pass through the interior of the L-shaped pipe member 60 of the contents spraying device 450, and then are introduced from the flow path 86 of the nozzle joint 480 through the groove 73a of the third cylindrical portion 73 of the nozzle 470 and the groove 484b for wide-angle mist spray of the fourth cylindrical portion 484 of the nozzle joint 480 to the first inlet path 451b of the mechanical breakup mechanism 451, and also from the flow path 87 of the nozzle joint 480 through the groove 74a of the fourth cylindrical portion 74 of the nozzle 470 and the groove 484c for wide-angle mist spray of the fourth cylindrical portion 484 of the nozzle joint 480 to the second inlet path 451c of the mechanical breakup mechanism 451. The contents introduced into first introduction path 451b of mechanical breakup mechanism 451 are introduced from first introduction path 451b into swirl chamber 451a of mechanical breakup mechanism 451. The contents introduced into second introduction path 451c of mechanical breakup mechanism 451 are introduced from second introduction path 451c into swirl chamber 451a of mechanical breakup mechanism 451. Therefore, the contents introduced into swirl chamber 451a via first introduction path 451b and second introduction path 451c swirl within swirl chamber 451a and are sprayed in a mist form from orifice 70a.
[0149] Next, the operation of the pump type product according to this embodiment in the narrow-angle mist spray mode will be described.
[0150] The user can place the content sprayer 450 in the state shown in Fig. 18 by rotating the nozzle 470 of the content sprayer 450 relative to the nozzle joint 480. When the content sprayer 450 is in the state shown in Fig. 18, the protrusion 85 of the nozzle joint 480 fits into the groove 71a of the first cylindrical portion 71 of the nozzle 470, so the nozzle 470 does not rotate easily relative to the nozzle joint 480.
[0151] When the content ejection device 450 is in the state shown in Figure 18, the user can, for example, hold the gripping portion 41a of the first part 41 of the handle 40 with the second, third, fourth and fifth fingers of the right or left hand, and operate the operating portion 42b of the second part 42 of the handle 40 with the first finger of the hand that is holding the gripping portion 41a of the first part 41 of the user's right or left hand, thereby changing the pump-type product of this embodiment from a state in which the handle 40 is open as shown in Figure 1(a) to a state in which the handle 40 is closed as shown in Figure 1(b). In the pump-type product of this embodiment, when the user changes the handle 40 to the closed state as shown in Figure 1(b), the protrusion 42c of the second part 42 of the handle 40 pushes the content spraying device 450 through the plate-like part 62 of the L-shaped pipe member 60, and the pump mounting part 61 of the L-shaped pipe member 60 of the content spraying device 450 pushes the moving part 32 of the pump 30 against the fixed part 31 of the pump 30, so that the contents inside the container 20 are expelled outside the container 20 by the pump 30.
[0152] The contents discharged from the container 20 by the pump 30 pass through the interior of the L-shaped pipe member 60 of the contents spraying device 450, and then are introduced from the flow path 86 of the nozzle joint 480 through the groove 73a of the third cylindrical portion 73 of the nozzle 470 and the groove 484d for narrow-angle mist spray of the fourth cylindrical portion 484 of the nozzle joint 480 to the first inlet path 452b of the mechanical breakup mechanism 452, and also from the flow path 87 of the nozzle joint 480 through the groove 74a of the fourth cylindrical portion 74 of the nozzle 470 and the groove 484e for narrow-angle mist spray of the fourth cylindrical portion 484 of the nozzle joint 480 to the second inlet path 452c of the mechanical breakup mechanism 452. The contents introduced into the first introduction path 452b of the mechanical breakup mechanism 452 are introduced from the first introduction path 452b into the swirl chamber 452a of the mechanical breakup mechanism 452. The contents introduced into the second introduction path 452c of the mechanical breakup mechanism 452 are introduced from the second introduction path 452c into the swirl chamber 452a of the mechanical breakup mechanism 452. Therefore, the contents introduced into the swirl chamber 452a via the first introduction path 452b and the second introduction path 452c swirl within the swirl chamber 452a and are sprayed in a mist form from the orifice 70a.
[0153] As described above, swirl chamber groove 480d is deeper than swirl chamber groove 480a. First introduction path groove 480e is wider and deeper in the circumferential direction of fourth cylindrical portion 484 than first introduction path groove 480b. Similarly, second introduction path groove 480f is wider and deeper in the circumferential direction of fourth cylindrical portion 484 than second introduction path groove 480c. Therefore, the flow velocity of the contents in swirl chamber 452a of mechanical breakup mechanism 452 is slower than the flow velocity of the contents introduced into swirl chamber 451a of mechanical breakup mechanism 451. Therefore, when the content spraying device 450 is in the state shown in Figure 18, the spray range of the content sprayed in mist form from the orifice 70a is narrower than the spray range of the content sprayed in mist form from the orifice 70a when the content spraying device 450 is in the state shown in Figure 17.
[0154] Next, the operation of the pump type product according to this embodiment in the injection stop mode will be described.
[0155] The user can place the content sprayer 450 in the state shown in Fig. 19 by rotating the nozzle 470 of the content sprayer 450 relative to the nozzle joint 480. When the content sprayer 450 is in the state shown in Fig. 19, the protrusion 85 of the nozzle joint 480 fits into the groove 71a of the first cylindrical portion 71 of the nozzle 470, so the nozzle 470 does not rotate easily relative to the nozzle joint 480.
[0156] In the pump-type product according to this embodiment, when the content-spraying device 450 is in the state shown in FIG. 19 , the groove 73a of the third cylindrical portion 73 of the nozzle 470 and the groove 74a of the fourth cylindrical portion 74 of the nozzle 470 are not in communication with the orifice 70a of the nozzle 470. In other words, the flow path is closed in the content-spraying device 450. Therefore, for example, even if a user holds the gripping portion 41a of the first portion 41 of the handle 40 with the second, third, fourth, and fifth fingers of their right or left hand and operates the operating portion 42b of the second portion 42 of the handle 40 with the first finger of the hand holding the gripping portion 41a of the first portion 41, the pump-type product according to this embodiment will not spray the contents from the orifice 70a, and the handle 40 will not change from the open state shown in FIG. 1( a) to the closed state shown in FIG. 1( b).
[0157] As described above, content spraying device 450 can be formed with a plurality of mechanical breakup mechanisms 451 each having orifices 70a for spraying the content of the pump-type product according to this embodiment, and can therefore spray the content in a mist form from the plurality of orifices 70a. Similarly, content spraying device 450 can be formed with a plurality of mechanical breakup mechanisms 452 each having orifices 70a for spraying the content of the pump-type product according to this embodiment, and can therefore spray the content in a mist form from the plurality of orifices 70a.
[0158] In the content injection device 450, in each of the multiple mechanical breakup mechanisms 451, of the first inlet passage 451b and the second inlet passage 451c for introducing the contents into the swirling chamber 451a, the contents are introduced into the first inlet passage 451b from the side opposite the center of the fourth cylindrical portion 484 of the nozzle joint 480, and the contents are introduced into the second inlet passage 451c from the center of the fourth cylindrical portion 484 with respect to the injection protrusion, so that the size of each of the multiple mechanical breakup mechanisms 451 in the circumferential direction can be reduced. Similarly, in each of the multiple mechanical breakup mechanisms 452, the content injection device 450 has a first inlet passage 452b and a second inlet passage 452c for introducing the content into the swirling chamber 452a, and the content is introduced into the first inlet passage 452b from the side opposite the center of the fourth cylindrical portion 484 of the nozzle joint 480, and the content is introduced into the second inlet passage 452c from the center of the fourth cylindrical portion 484 with respect to the injection protrusion, so that the size of each of the multiple mechanical breakup mechanisms 452 in the circumferential direction can be reduced.
[0159] In the content spraying device 450, the swirl chamber groove 480a, the first introduction passage groove 480b, and the second introduction passage groove 480c for the wide-angle mist spray mode, and the swirl chamber groove 480d, the first introduction passage groove 480e, and the second introduction passage groove 480f for the narrow-angle mist spray mode are formed in the fourth cylindrical portion 484 of the nozzle joint 480. Therefore, the spray range can be changed by the width and depth of the swirl chamber groove, the first introduction passage groove, and the second introduction passage groove formed in the fourth cylindrical portion 484. Therefore, compared to the content spraying device 50 according to the first embodiment, which changes the spray range depending on the width of the flow path to the mechanical breakup mechanism, the content spraying device 450 can reduce the difference in the force required for operation by the user when spraying the contents in a wide mist angle and when spraying the contents in a narrow mist angle, and can easily realize the spray range desired by the developer.
[0160] In this embodiment, the swirl chamber groove 480a and the swirl chamber groove 480d have the same diameter. However, in the pump-type product according to this embodiment, the diameter of the swirl chamber groove 480a and the diameter of the swirl chamber groove 480d may be different.
[0161] (Sixth embodiment) First, the configuration of a pump type product according to the sixth embodiment of the present invention will be described.
[0162] Among the components of the pump-type product of this embodiment, those components that are similar to the components of the pump-type product of the fifth embodiment will be given the same symbols as the components of the pump-type product of the fifth embodiment, and detailed explanations will be omitted.
[0163] Fig. 22(a) is a front view of a content spraying device 550 for a pump type product according to this embodiment when spraying the content straight. Fig. 22(b) is a cross-sectional view taken along the arrow JJ in Fig. 22(a).
[0164] The configuration of the pump-type product of this embodiment is the same as the configuration of the pump-type product of the fifth embodiment, except that the content spraying device 550 shown in Figure 22 is replaced with the content spraying device 450 (see Figures 17 to 19).
[0165] FIG. 23 is a front view of a nozzle joint 580 of a pump-type product according to this embodiment.
[0166] The configuration of the content ejection device 550 is the same as the configuration of the content ejection device 450, except that the nozzle joint 580 shown in FIG. 23 is replaced with the nozzle joint 480 (see FIG. 21).
[0167] The configuration of the nozzle joint 580 is the same as that of the nozzle joint 480, except that a fourth cylindrical portion 584 as the annular protrusion of the present invention is provided instead of the fourth cylindrical portion 484 (see FIG. 21).
[0168] The configuration of the fourth cylindrical portion 584 is similar to that of the fourth cylindrical portion 484, except that it has a straight injection groove 585 for introducing the contents into the orifice 70a of the nozzle 470 when the contents injection mode is the straight injection mode, instead of the mist narrow-angle injection groove 484d (see Figure 21), the mist narrow-angle injection groove 484e (see Figure 21), the swirl chamber groove 480d (see Figure 21), the first introduction path groove 480e (see Figure 21), and the second introduction path groove 480f (see Figure 21).
[0169] Three straight injection grooves 585 are formed at equal intervals on the circumference of the same circle in the fourth cylindrical portion 584. The straight injection groove 585 includes: a portion 585a formed on the outer peripheral surface of the fourth cylindrical portion 584 to communicate with the groove 73a in the third cylindrical portion 73 of the nozzle 470; a portion 585b formed on the inner peripheral surface of the fourth cylindrical portion 584 to communicate with the groove 74a in the fourth cylindrical portion 74 of the nozzle 470; and a portion 585c formed on the end portion 84a of the fourth cylindrical portion 584 to communicate with the portion 585a, the portion 585b, and the orifice 70a of the nozzle 470.
[0170] Next, the operation of the pump type product according to this embodiment will be described.
[0171] The content spraying device 550 can switch the content spraying mode by rotating the nozzle 470 relative to the fourth cylindrical portion 584 of the nozzle joint 580. The content spraying modes include a wide-angle mist spray mode, a straight spray mode, and a stop spray mode.
[0172] First, the operation of the pump-type product of this embodiment in the mist wide-angle spray mode and the operation of the pump-type product of this embodiment in the spray stop mode are similar to the operation of the pump-type product of the fifth embodiment in the mist wide-angle spray mode and the operation of the pump-type product of the fifth embodiment in the spray stop mode, respectively.
[0173] Next, the operation of the pump type product according to this embodiment in the straight injection mode will be described.
[0174] The user can place the content sprayer 550 in the state shown in Fig. 22 by rotating the nozzle 470 of the content sprayer 550 relative to the nozzle joint 580. When the content sprayer 550 is in the state shown in Fig. 22, the protrusion 85 of the nozzle joint 580 fits into the groove 71a of the first cylindrical portion 71 of the nozzle 470, so the nozzle 470 does not rotate easily relative to the nozzle joint 580.
[0175] When the content ejection device 550 is in the state shown in Figure 22, the user can, for example, hold the gripping portion 41a of the first part 41 of the handle 40 with the second, third, fourth and fifth fingers of the right or left hand, and operate the operating portion 42b of the second part 42 of the handle 40 with the first finger of the hand that is holding the gripping portion 41a of the first part 41 of the user's right or left hand, thereby changing the pump-type product of this embodiment from a state in which the handle 40 is open as shown in Figure 1(a) to a state in which the handle 40 is closed as shown in Figure 1(b). In the pump-type product of this embodiment, when the user changes the handle 40 to the closed state as shown in Figure 1(b), the protrusion 42c of the second part 42 of the handle 40 pushes the content spraying device 550 through the plate-like part 62 of the L-shaped pipe member 60, and the pump mounting part 61 of the L-shaped pipe member 60 of the content spraying device 550 pushes the moving part 32 of the pump 30 against the fixed part 31 of the pump 30, so that the contents inside the container 20 are expelled outside the container 20 by the pump 30.
[0176] The contents discharged from container 20 by pump 30 pass through L-shaped pipe member 60 of content-spraying device 550, then pass from flow path 86 of nozzle joint 580 through groove 73a of third cylindrical portion 73 of nozzle 470 to straight spray groove 585 of fourth cylindrical portion 584 of nozzle joint 580, and then pass from flow path 87 of nozzle joint 580 to groove 74a of fourth cylindrical portion 74 of nozzle 470 to straight spray groove 585 of fourth cylindrical portion 584 of nozzle joint 580. Therefore, the contents introduced into straight spray groove 585 of fourth cylindrical portion 584 of nozzle joint 580 are sprayed straight from orifice 70a.
[0177] As described above, the content injection device 550 has a straight injection groove 585 formed in the fourth cylindrical portion 584 for introducing the content into the orifice 70a, so the content can be injected more directly from the orifice compared to the content injection device 150 of the second embodiment, in which a straight injection groove 185 for introducing the content into the swirling chamber groove 70b for forming the swirling chamber 51a of the mechanical breakup mechanism 51 is formed in the fourth cylindrical portion 184.
[0178] In the present embodiment, the content-spraying device 550 is introduced into the fourth cylindrical portion 584 from the side of the straight spray groove 585 opposite to the center side of the fourth cylindrical portion 584 and from the center side of the fourth cylindrical portion 584. However, as in the third embodiment, the content-spraying device 550 may be introduced into the fourth cylindrical portion 584 from only the center side of the fourth cylindrical portion 584, out of the side of the straight spray groove 585 opposite to the center side of the fourth cylindrical portion 584 and the center side of the fourth cylindrical portion 584, or as in the fourth embodiment, the content may be introduced into the fourth cylindrical portion 584 from only the side of the straight spray groove 585 opposite to the center side of the fourth cylindrical portion 584 and the center side of the fourth cylindrical portion 584.
[0179] In the content injection device 50 according to the first embodiment, a swirl chamber groove 70b, a first introduction passage groove 70c, and a second introduction passage groove 70d for forming the mechanical breakup mechanisms 51 and 52 are formed in the nozzle 70. In the content injection device 150 according to the second embodiment, the content injection device 250 according to the third embodiment, and the content injection device 350 according to the fourth embodiment, the swirl chamber groove 70b, a first introduction passage groove 70c, and a second introduction passage groove 70d for forming the mechanical breakup mechanism 51 are formed in the nozzle 70. In a content injection device 450 according to the fifth embodiment, a swirl chamber groove 480a, a first introduction passage groove 480b, and a second introduction passage groove 480c for forming a mechanical breakup mechanism 451, and a swirl chamber groove 480d, a first introduction passage groove 480e, and a second introduction passage groove 480f for forming a mechanical breakup mechanism 452 are formed in a nozzle joint 480. In a content injection device 550 according to the sixth embodiment, a swirl chamber groove 480a, a first introduction passage groove 480b, and a second introduction passage groove 480c for forming a mechanical breakup mechanism 451 are formed in a nozzle joint 580. In the content injection device, it is sufficient that a groove for forming a mechanical breakup mechanism is formed in at least one of the nozzle and the nozzle joint.
[0180] The content spraying device in each of the above-described embodiments is provided in a pump-type product. However, the content spraying device in each of the above-described embodiments may also be provided in an aerosol product to spray the contents inside the container of the aerosol product.
