[0002] As an existing content spraying device, a content spraying device with an elliptical nozzle is known, wherein the shape of the spraying range of the contents of a pump-type product or an aerosol product is elliptical when viewed from the front (for example, see Patent Documents 1-3).

[0003] Existing technical documents Patent documents Patent Document 1: Japanese Patent Application Publication No. 2011-139994 Patent Document 2: Japanese Patent Application Publication No. 2011-177677 Patent Document 3: International Publication No. 2016 / 140142 Summary of the Invention

[0004] (a) Technical problems to be solved However, the contents ejection devices described in Patent Documents 1-3 have the problem that the shapes of the contents ejection ranges are roughly the same.

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

[0006] (II) Technical Solution The contents ejection device of the present invention is characterized by comprising: a first nozzle, which, when viewed from the front, extends the ejection range of the contents of a pump-type or aerosol product in a specific direction than in all directions other than the specific direction; and a second nozzle, which, when viewed from the front, ejects the contents toward a direction between the specific direction and a direction orthogonal to the specific direction.

[0007] According to this structure, the content ejection device of the present invention includes: a first nozzle, which, when viewed from the front, extends the ejection range of the content of a pump-type product or an aerosol product in a specific direction more than in all directions other than the specific direction; and a second nozzle, which, when viewed from the front, ejects the content in a direction between the specific direction and a direction orthogonal to the specific direction, thereby enabling a new shape to be achieved as the shape of the content ejection range by means of the first nozzle and the second nozzle.

[0014] In the content ejection device of the present invention, when viewed from the front, if the specific direction is the up-down direction, the second nozzles that eject the content toward the upper left direction, the second nozzles that eject the content toward the upper right direction, the second nozzles that eject the content toward the lower left direction, and the second nozzles that eject the content toward the lower right direction are arranged at equal intervals on the circumference of the same circle.

[0015] According to this structure, the content ejection device of the present invention can achieve a new shape as the shape of the content ejection range, and eject the content evenly over a large area.

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

[0033] Hereinafter, embodiments of the present invention will be described using the accompanying drawings.

[0034] First, the structure of an aerosol product according to one embodiment of the present invention will be described.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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. 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.

[0041] 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.

[0042] 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). Figure 5 yes Figure 3 CC-direction sectional view in (a).

[0043] like Figure 1 , Figure 3 , Figure 4 as well as Figure 5 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.

[0044] The nozzle 70 has an internally passable elliptical nozzle 73 in the center as a first nozzle. When spraying contents, the spray range of the contents is elliptical when viewed from the front. The elliptical nozzle 73 communicates with the space on the inner periphery of the central protrusion 72. The space on the inner periphery of the central protrusion 72 forms a flow path for the contents (hereinafter referred to as the "third flow path") 20c.

[0045] The nozzle 70 has four spray nozzles 74 serving as second nozzles, which spray contents in a specific direction other than the frontal direction. The four spray nozzles 74 are arranged at equal intervals in the same circle (hereinafter referred to as the "spray nozzle arrangement circle") 70a (see reference). Figure 6 When ejecting contents, when viewed from the front, if the major axis of the elliptical shape of the ejection range of the contents from the elliptical nozzle 73 extends vertically, the four ejection nozzles 74 are configured as follows: one ejecting contents towards the upper left, one towards the upper right, one towards the lower left, and one towards the lower right. Generally, ejection nozzles 74 that eject contents in a specific direction other than the frontal direction require a smaller flow rate of contents compared to internally channeled elliptical nozzles.

[0046] Next, the spraying of the contents of the aerosol product 10 will be described.

[0047] 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.

[0048] 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 and the third flow path 20c. The contents introduced into the first flow path 20a and the second flow path 20b are sprayed from the four spray nozzles 74 in a specific direction. The contents introduced into the third flow path 20c are sprayed from the elliptical nozzle 73 in an elliptical shape.

[0049] Figure 6 (a) is a front view of the aerosol product 10 with the contents sprayed, near the nozzle 70. Figure 6 (b) is a side sectional view of the aerosol product 10 with the contents of the sprayed product near the nozzle 70.

[0050] exist Figure 6 In the diagram, the dashed line indicates the extent of the contents sprayed from the aerosol product 10. For example... Figure 6As shown, the aerosol product 10 can spray its contents in an elliptical shape from the elliptical nozzle 73, and can spray its contents in a specific direction from the four nozzles 74.

[0051] As described above, the button cover 20 includes: an elliptical nozzle 73, which, when viewed from the front, allows the spray range of the contents of the aerosol product 10 to be longer in the vertical direction than in all other directions; and a spray nozzle 74, which, when viewed from the front, sprays the contents in a direction between the vertical direction and the left-right direction orthogonal to the vertical direction. Therefore, a new shape can be achieved as the shape of the spray range of the contents through the elliptical nozzle 73 and the spray nozzle 74.

[0052] The content ejection device described in Patent Documents 1-3 has three nozzles. However, the device with a button cover 20 has a total of five nozzles, including an elliptical nozzle 73 and four ejection ports 74. When the amount of content ejected is the same for the entire content ejection device, more nozzles allow for a smaller nozzle diameter, thus reducing the amount of content ejected from each nozzle. A smaller amount of content ejected from each nozzle reduces the noise level when content is ejected from the nozzle.

[0053] Figure 7 (a) is a front view of the aerosol product 10 in the state of spraying the contents by the user operating it with their left hand. Figure 7 (b) is a front view of the aerosol product 10 in the state of spraying the contents by the user operating it with their right hand.

[0054] When viewed from the front, and the major axis of the elliptical shape extending in the direction of the spray range of the contents from the elliptical nozzle 73 is vertical, the button-cover 20 has a spray nozzle 74 that sprays the contents in the upward-left direction. Therefore, as Figure 7 As shown in (a), when a user holds the aerosol product 10 with their left hand and operates the button-cap 20 with their left hand to spray the contents towards the front, there is a spray range of the contents based on the spray nozzle 74 at or near the position in front of the user's eyes. Similarly, when viewed from the front, with the vertical direction being vertical, the button-cap 20 has a spray nozzle 74 that sprays the contents towards the upper right direction, therefore... Figure 7 As shown in (b), when a user holds the aerosol product 10 with their right hand and operates the button cap 20 with their right hand to spray the contents in front of them, there is a spray range of the contents based on the spray nozzle 74 at or near the position in front of the user's eyes. Therefore, the button cap 20 can visually emphasize the spray of the contents to the user.

[0055] When viewed from the front, with the major axis of the elliptical shape of the spray range based on the elliptical nozzle 73 extending vertically, the button-cover 20 has a spray nozzle 74 that sprays the contents towards the upper left and a spray nozzle 74 that sprays the contents towards the upper right. According to this structure, for the button-cover 20, whether the user holds the aerosol product 10 with their left hand and operates the button-cover 20 with their left hand to spray the contents towards the front, or the user holds the aerosol product 10 with their right hand and operates the button-cover 20 with their right hand to spray the contents towards the front, the spray range based on the spray nozzle 74 exists at or near the user's field of vision. Therefore, regardless of whether the user holds the aerosol product 10 with their left hand and operates the button-cover 20 with their left hand to spray the contents towards the front, or the user holds the aerosol product 10 with their right hand and operates the button-cover 20 with their right hand to spray the contents towards the front, the spraying of the contents can be visually emphasized to the user.

[0056] When viewed from the front, with the major axis of the elliptical shape extending in the direction of vertical extension based on the shape of the spray range of the contents from the elliptical nozzle 73, the button cover 20 has a spray nozzle 74 that sprays contents in the upper left direction, a spray nozzle 74 that sprays contents in the upper right direction, a spray nozzle 74 that sprays contents in the lower left direction, and a spray nozzle 74 that sprays contents in the lower right direction. 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 wide area.

[0057] like Figure 6 As shown, the four nozzles 74 with the button cover 20 are arranged at equal intervals on the circumference of the same nozzle arrangement circle 70a. Therefore, a new shape can be achieved as the shape of the spray range of the contents, and the contents can be sprayed evenly over a large area. In addition, the four nozzles 74 with the button cover 20 are arranged on the circumference of the same nozzle arrangement circle 70a, but they may not be arranged at equal intervals, and the four nozzles 74 may not be arranged on the circumference of the same circle.

[0058] Figure 8 Is with Figure 2 (a) is a front view of a portion of the cover body 30 in a different structure.

[0059] In this embodiment, the protrusion 53 is annular. However, the protrusion 53 may not be annular. For example, as... Figure 8 As shown, the protrusions 53 can be segmented for each injection port 74.

[0060] The button cover 20 may not have at least one of the four spray nozzles 74.

[0061] The button cover 20 can have an elliptical nozzle other than the internal passage type as the first nozzle to replace the internal passage type elliptical nozzle 73.

[0062] Figure 9 (a) is a front view of nozzle 170, which is different from nozzle 70. Figure 9 (b) is a rear view of nozzle 170. Figure 10 (a) is Figure 9 (a) DD-direction sectional view. Figure 10 (b) is Figure 9 (a) EE-directed sectional view.

[0063] The 20 model with a button cover can also be equipped with this feature. Figure 9 and Figure 10 The nozzle 170 shown replaces nozzle 70 (see reference). Figures 3-5 ).

[0064] like Figure 9 and Figure 10 As shown, the structure of the nozzle 170 is the same as the structure described below, that is, the nozzle 70 has a baffle-type elliptical nozzle 173 as the first nozzle instead of the elliptical nozzle 73 (see reference). Figure 3 and Figure 4 When the elliptical nozzle 173 sprays contents, the spray range of the contents is elliptical when viewed from the front. Generally, compared with the internal passage type elliptical nozzle, a baffle-type elliptical nozzle requires a larger flow rate of contents to spray contents in an elliptical shape.

[0065] 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 the elliptical nozzle 173, just like when the button cover 20 has a nozzle 70, and can spray the contents in a specific direction from the four nozzles 74.

[0066] When the button cover 20 is viewed from the front, if the first nozzle is an elliptical nozzle and the spray range of the contents is longer in the vertical direction than in all other directions, the shape of the spray range of the contents based on the first nozzle can be made into a well-balanced shape. However, the button cover 20 may also have a nozzle other than an elliptical nozzle as the first nozzle, which, when viewed from the front, has a spray range of the contents longer in the vertical direction than in all other directions.

[0067] 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.
