[0029] Hereinafter, embodiments of the present invention will be described using the accompanying drawings.

[0030] (First Implementation) First, the structure of the aerosol product according to the first embodiment of the present invention will be described.

[0031] Figure 1 (a) is a top view of a portion of the aerosol product 10 of this embodiment. Figure 1 (b) is a side sectional view of a portion of the aerosol product 10.

[0032] like Figure 1 As shown, the aerosol product 10 includes: a container (not shown) containing contents for external discharge; a valve (not shown) installed in the container, which, when a portion is pressed, discharges the contents of the container to the outside; and a button cover 20 as a content dispensing device, which is installed on the valve stem for pressing a portion of the valve to spray the contents discharged to the outside of the container through the valve.

[0033] The button-type cover 20 includes a cover body 30 mounted on the container and a nozzle 70 mounted on the cover body 30 for spraying the contents.

[0034] Figure 2 (a) is a front view of a portion of the cover body 30. Figure 2 (b) is a side sectional view of a portion of the cover body 30.

[0035] like Figure 1 and Figure 2 As shown, the cover body 30 includes: a container mounting portion 40, which is mounted on a container; a button portion 50, which is pressed by a user; and a flexible support portion 60, which is flexible and supports the button portion 50 side so that it can move relative to the container mounting portion 40 side.

[0036] The button portion 50 includes: a rod mounting portion 51, which is mounted on the valve rod; a head mounting portion 52, which has a circular hole (hereinafter referred to as "head insertion hole") 52a for inserting the nozzle 70, by inserting the nozzle 70 into the head insertion hole 52a; and an annular protrusion 53, which is disposed inside the head insertion hole 52a of the head mounting portion 52. In order to prevent the nozzle 70 from falling out of the head insertion hole 52a, the head insertion hole 52a has two grooves (hereinafter referred to as "anti-falling grooves") 52b for partially inserting the nozzle 70.

[0037] The button portion 50 has: a flow path 50a for the flow of contents discharged from the rod mounted on the rod mounting portion 51; two openings 50b for connecting the flow path 50a to the space on the inner peripheral side of the head mounting portion 52 and the outer peripheral side of the protrusion 53; and an opening 50c for connecting the flow path 50a to the space on the inner peripheral side of the protrusion 53.

[0038] Figure 3 (a) is the front view of nozzle 70. Figure 3 (b) is a rear view of nozzle 70. Figure 4 (a) is Figure 3 AA-direction sectional view in (a). Figure 4 (b) is Figure 3 BB-direction sectional view in (a).

[0039] like Figure 1 , Figure 3 as well as Figure 4 As shown, the nozzle 70 includes: an annular main body mounting portion 71, which is mounted on the outer peripheral side of the head mounting portion 52 of the cover body 30; and an annular central protrusion 72, which is disposed on the inner peripheral side of the main body mounting portion 71. The main body mounting portion 71 has four flow path forming protrusions 71a on its inner peripheral surface. These flow path forming protrusions 71a form a flow path (hereinafter referred to as "first flow path") 20a between the inner peripheral surface of the main body mounting portion 71 and the outer peripheral surface of the protrusion 53 of the cover body 30 by contacting the outer peripheral surface of the protrusion 53. The main body mounting portion 71 has an anti-detachment groove 52b embedded in the cover body 30 (see reference). Figure 2 (b). ) Two protrusions 71b. The central protrusion 72 has four flow path forming protrusions 72a at four locations on its outer peripheral surface. These flow path forming protrusions 72a form a flow path (hereinafter referred to as "second flow path") between the inner peripheral surface of the protrusion 53 and the outer peripheral surface of the central protrusion 72 by contacting the inner peripheral surface of the protrusion 53. 20b.

[0040] The nozzle 70 has six baffle-type elliptical nozzles 73, wherein, when spraying contents, the spray range of the contents is elliptical when viewed from the front. The six elliptical nozzles 73 are arranged at equal intervals in the same circle (hereinafter referred to as the "elliptical nozzle arrangement circle") 70a (see reference). Figure 5 On the circumference of the elliptical nozzle 73, when spraying contents, the shape of the spray range of the contents, when viewed from the front, is such that the direction of extension of the major axis does not pass through the center 70b of the elliptical nozzle configuration circle 70a (see reference). Figure 5 It has an oval shape.

[0041] Next, the spraying of the contents of the aerosol product 10 will be described.

[0042] The user can press the button 50. For the aerosol product 10, if the user presses the button 50, a part of the valve is pressed by the button 50, and the contents inside the container are discharged to the outside of the container by the valve.

[0043] The contents discharged from the valve to the outside of the container pass through the flow path 50a of the button section 50, and are then introduced from the flow path 50a through the opening 50b into the first flow path 20a, and from the flow path 50a through the opening 50c into the second flow path 20b. The contents introduced into the first flow path 20a and the second flow path 20b are sprayed out in an elliptical shape from the six elliptical nozzles 73.

[0044] Figure 5 (a) is a front view of the aerosol product 10 with the contents sprayed, near the nozzle 70. Figure 5 (b) is a side sectional view of the aerosol product 10 with the contents of the sprayed product near the nozzle 70.

[0045] exist Figure 5 In the diagram, the dashed line indicates the extent of the contents sprayed from the aerosol product 10. For example... Figure 5 As shown, the aerosol product 10 can spray its contents in an elliptical shape from six elliptical nozzles 73.

[0046] As explained above, Figure 5 As shown, in the button cover 20, each of the six elliptical nozzles 73 overlaps with a portion of the spray range of the other four elliptical nozzles 73, thus enabling a new shape as the shape of the spray range of the contents.

[0047] like Figure 5 As shown, the six elliptical nozzles 73 with the button cover 20 are arranged at equal intervals on the circumference of the same elliptical nozzle arrangement circle 70a, thus enabling a new shape as the shape of the spray range of the contents, and spraying the contents over a wide area. Alternatively, the six elliptical nozzles 73 with the button cover 20 may not be arranged on the same circumference.

[0048] like Figure 5 As shown, when viewed from the front, the shape of the spray range of the elliptical nozzle 73 with the button cover 20 is an elliptical shape in which the extension direction of the major axis does not pass through the center 70b of the elliptical nozzle arrangement circle 70a with six elliptical nozzles 73. Therefore, the shape of the spray range of the contents is close to a circle, and a new shape can be achieved as the spray range of the contents. Alternatively, the shape of the spray range of the elliptical nozzle 73 when viewed from the front, with the button cover 20, can also be an elliptical shape in which the extension direction of the major axis passes through the center 70b of the elliptical nozzle arrangement circle 70a with six elliptical nozzles 73.

[0049] Figure 6 Is with Figure 2 (a) is a front view of a portion of the cover body 30 in a different structure.

[0050] In this embodiment, the protrusion 53 is annular. However, the protrusion 53 may not be annular. For example, as... Figure 6 As shown, protrusions 53 can be divided for each elliptical nozzle 73.

[0051] In this embodiment, the nozzle 70 corresponds to six elliptical nozzles 73. However, the nozzle 70 may also correspond to multiple elliptical nozzles 73 beyond six. With the same ejection volume of the contents as a whole (including the button cover 20), the more elliptical nozzles 73 there are, the smaller the throttling orifice of the elliptical nozzle 73 can be, thus reducing the ejection volume of the contents from each throttling orifice. The smaller the ejection volume of the contents from each throttling orifice, the less noise is generated when the contents are ejected from the throttling orifice.

[0052] The button cover 20 can also have an elliptical nozzle other than a baffle type to replace the baffle type elliptical nozzle 73.

[0053] Figure 7 (a) is a front view of nozzle 170, which is different from nozzle 70. Figure 7 (b) is a rear view of nozzle 170. Figure 8 (a) is Figure 7 (a) CC-direction sectional view. Figure 8 (b) is Figure 7 (a) DD-direction sectional view.

[0054] The 20 model with a button cover can also be equipped with this feature. Figure 7 and Figure 8 The nozzle 170 shown replaces nozzle 70 (see reference). Figure 3 and Figure 4 ).

[0055] like Figure 7 and Figure 8 As shown, the structure of nozzle 170 is the same as the structure described below, that is, nozzle 70 has an internally passable elliptical nozzle 173 instead of an elliptical nozzle 73 (see reference). Figure 3 and Figure 4 In this configuration, when the elliptical nozzle 173 sprays contents, the spray range of the contents is elliptical when viewed from the front. Six elliptical nozzles 173 are arranged at equal intervals on the circumference of the same elliptical nozzle arrangement circle. When the elliptical nozzle 173 sprays contents, the spray range of the contents, when viewed from the front, is elliptical in shape, with its major axis extending beyond the center of the elliptical nozzle arrangement circle. Generally, compared to a baffle-type elliptical nozzle, an internal passage type elliptical nozzle requires a smaller flow rate of contents to spray in an elliptical shape.

[0056] When the aerosol product 10 has a nozzle 170 instead of a nozzle 70 on the button cover 20, it can spray the contents in an elliptical shape from six elliptical nozzles 173, just like when the button cover 20 has a nozzle 70.

[0057] When viewed from the front, the button cover 20 can achieve a well-balanced shape for the spray range of the contents based on the nozzle, where the spray range of the contents is longer in a specific direction than in all other directions. However, the button cover 20 may also have a nozzle other than an elliptical nozzle, such that, when viewed from the front, the spray range of the contents is longer in a specific direction than in all other directions.

[0058] In this embodiment, the button cap 20 is provided for an aerosol product. However, the button cap 20 can also be provided for a pump product to hold the contents inside the container of a pump-type product.

[0059] (Second Implementation) First, the structure of the aerosol product according to the second embodiment of the present invention will be described.

[0060] Regarding the constituent elements of the aerosol product of this embodiment, and the aerosol product 10 of the first embodiment (refer to...) Figure 1 The constituent elements are the same as those of the aerosol product 10, and the same reference numerals are used in the accompanying drawings, with detailed descriptions omitted.

[0061] Figure 9 (a) is a front view of the nozzle 270 of the aerosol product of this embodiment. Figure 9 (b) is a rear view of nozzle 270.

[0062] The structure of the aerosol product in this embodiment is the same as that of aerosol product 10. Figure 9 The nozzle 270 shown replaces nozzle 70 (see reference). Figure 3 The structure of 。 is the same.

[0063] like Figure 9 As shown, the structure of the nozzle 270 is the same as the structure described below, that is, the nozzle 70 has three baffle-type elliptical nozzles 273 instead of six baffle-type elliptical nozzles 73 (see reference). Figure 5 (a). , wherein, when the elliptical nozzle 273 sprays contents, when viewed from the front, the shape of the spray range of the contents is a circle 270a arranged through the elliptical nozzle along the extension direction of the major axis (refer to...). Figure 10 The center of 270b (refer to) Figure 10The elliptical nozzle 73, when spraying contents, has a spray range whose major axis does not extend through the elliptical nozzle configuration circle 70a (see reference 70a) when viewed from the front. Figure 5 (a).) Center 70b (refer to) Figure 5 The elliptical shape of (a). Three elliptical nozzles 273 are arranged at equal intervals on the circumference of the same elliptical nozzle arrangement circle 270a.

[0064] Next, the spraying of the contents of the aerosol product based on this embodiment will be described.

[0065] The user can press the button 50. In the aerosol product of this embodiment, if the user presses the button 50, a part of the valve is pressed by the button 50, and the contents inside the container are discharged to the outside of the container by the valve.

[0066] The contents discharged from the valve to the outside of the container pass through the flow path 50a of the button section 50, and are then introduced into the first flow path 20a through the opening 50b, and into the second flow path 20b through the opening 50c. The contents introduced into the first flow path 20a and the second flow path 20b are sprayed out in an elliptical shape from the three elliptical nozzles 273.

[0067] Figure 10 (a) is a front view of the aerosol product in the state of spraying contents, near nozzle 270. Figure 10 (b) is a side sectional view of the aerosol product in the state of spraying contents near nozzle 270.

[0068] exist Figure 10 In the diagram, the dashed line indicates the extent of the contents ejected from the aerosol product of this embodiment. For example... Figure 10 As shown, the aerosol product of this embodiment can spray its contents in an elliptical shape from three elliptical nozzles 273.

[0069] As explained above, Figure 10 As shown, in the button-covered embodiment, each of the three elliptical nozzles 273 overlaps with a portion of the spray range of the other two elliptical nozzles 273, thus enabling a new shape to be achieved as the shape of the spray range of the contents.

[0070] like Figure 10 As shown, in this embodiment, the three elliptical nozzles 273 with button covers are arranged at equal intervals on the circumference of the same elliptical nozzle arrangement circle 270a. Therefore, a new shape can be achieved as the shape of the spray range of the contents, and the contents can be sprayed over a large area. Alternatively, the three elliptical nozzles 273 with button covers in this embodiment may not be arranged on the circumference of the same circle.

[0071] In this embodiment, the protrusion 53 is annular. However, the protrusion 53 may not be annular.

[0072] In this embodiment, the nozzle 270 corresponds to three elliptical nozzles 273. However, the nozzle 270 may also correspond to multiple elliptical nozzles 273 beyond three. Given the same ejection volume of the contents of the button-cover assembly in this embodiment, the more elliptical nozzles 273 there are, the smaller the throttling orifice of the elliptical nozzle 273 can be, thus reducing the ejection volume of the contents from each throttling orifice. The smaller the ejection volume of the contents from each throttling orifice, the less noise is generated when ejecting the contents from the throttling orifice.

[0073] The button-type cover of this embodiment may also have an elliptical nozzle other than a baffle type instead of the baffle-type elliptical nozzle 273. For example, the button-type cover of this embodiment may also have an internal passage type elliptical nozzle instead of the baffle-type elliptical nozzle 273.

[0074] In this embodiment, when viewed from the front, the button-operated cover allows for a well-balanced shape of the content spray range based on the nozzle, where the spray range of the contents is longer in a specific direction than in all other directions. However, the button-operated cover of this embodiment may also have a nozzle other than an elliptical nozzle, such that, when viewed from the front, the content spray range is longer in a specific direction than in all other directions.

[0075] In this embodiment, the button-operated cap is provided for an aerosol product. However, for the contents inside the container of a pump-type product, the button-operated cap can also be provided for a pump-type product.
