For example, in Patent Literature 1, a plurality of discharge ports (forming holes) are provided in a top wall (modeling wall), and the forming elements of contents discharged from these discharge ports are combined on the surface of the top wall. An ejection cap (modeling head) on which a predetermined model is formed is shown. According to the discharge container provided with such a discharge cap, various shaped objects can be formed according to the size, shape, and position of the discharge port.

JP 2016-26962 A

  By the way, when the content is discharged from such a plurality of discharge ports, generally, the one provided near the center portion is easier to discharge the content than the discharge port provided near the outer edge portion of the discharge cap. There is a tendency. This will be described with reference to the discharge container 100 shown in FIG.

  The discharge container 100 shown in FIGS. 3A and 3B is one in which a discharge cap 103 is attached to an opening 102 of a container main body 101 that stores contents. Although not shown, the container main body 101 has a flexible body. The discharge cap 103 includes a plate-shaped top wall 104, and the top wall 104 is provided with a plurality of discharge ports 105 penetrating therethrough. The discharge port 105 of the present embodiment has a total of three innermost discharge ports 105a provided at positions closest to the central axis C2 of the container body 101, and a side farther from the central axis C2 than the innermost discharge port 105a. , A total of eight second outer discharge ports 105c provided on the side farther from the center axis C2 than the first outer discharge ports 105b, and a second outer discharge port 105c A total of twelve third outer discharge ports 105d are provided on the side farther from the center axis C2 than the outlet 105c. The innermost outlet 105a, the first outer outlet 105b, the second outer outlet 105c, and the third outer outlet 105d are all circular holes, and have the same outer diameter and depth.

  In the illustrated discharge container 100, when the body of the container main body 101 is pressed, the contents are pressurized, and as a result, as illustrated in FIG. 3C, the discharge port 105 (the innermost discharge port 105a, the first outer The contents are discharged from the discharge port 105b, the second outside discharge port 105c, and the third outside discharge port 105d). The discharge state of the contents varies depending on the outer diameter of the discharge port 105 and the properties (viscosity and type, etc.) of the contents, but when the outer diameter and the depth of the discharge ports 105 are all equal as in the present embodiment, Generally, as shown in the figure, the amount of the content discharged from the innermost discharge port 105a is the largest, and the amount of the content tends to decrease as the distance from the center axis C2 increases.

  Here, as a method of equalizing the amount of the content discharged from each of the discharge ports 105, the first outer discharge port 105b, the second outer discharge port 105c, and the outer diameter of the innermost discharge port 105a are maintained. It is conceivable to increase the outer diameter of the third outer discharge port 105d (in particular, to increase the outer diameter of the third outer discharge port 105d). However, depending on the shape of the molded object, the intended shape may not be obtained if the outer diameter of the third outer discharge port 105d is too large. On the other hand, it is also possible to employ a means for reducing the outer diameter of the innermost discharge port 105a by keeping the outer diameter of the third outer discharge port 105d within a certain range, but the outer diameter of the innermost discharge port 105a is too small. When forming the discharge cap 103 with a mold, there are difficulties in terms of moldability and mold strength. Therefore, when adjusting the amount of the content to be discharged, there is a limit in responding only by changing the outer diameter of the discharge port 105.

  The present invention has been made in view of such circumstances, and in forming a shaped object having a predetermined shape by the discharged contents, the amount of the contents is limited even if there is a limit only by changing the outer diameter of the discharge port. It is an object of the present invention to provide a discharge container capable of adjusting the pressure.

The present invention provides a container body having a filling space for accommodating contents, a mouth communicating with the filling space, a top wall covering the mouth, and discharging the contents of the filling space through the top wall. A discharge cap having a discharge cap having a plurality of discharge ports,
The plurality of outlets are constituted by an innermost outlet closest to the central axis of the container body and an outer outlet except the innermost outlet,
The outer discharge port has an outer diameter equal to or greater than the outer diameter of the innermost discharge port, and the innermost discharge port is a discharge container having a depth greater than the depth of the outer discharge port.

  It is preferable that the outer outlet has an outer diameter equal to or larger than the outer diameter of the innermost outlet and equal to or less than twice the outer diameter of the innermost outlet.

  The outer diameter of the innermost discharge port is preferably 0.3 mm or more.

  It is preferable that the outer discharge ports are arranged in order of increasing depth as the distance from the central axis increases radially outward.

  According to the discharge container of the present invention, even when it is difficult to increase the amount of contents from the outer discharge port to the innermost discharge port within the allowable outer diameter range, the depth of the innermost discharge port is set to the outer discharge port. Since the flow resistance at the innermost discharge port is increased by making the depth greater than the depth of the outlet, the discharge amount from the innermost discharge port is suppressed, and the discharge amount from the outer discharge port can be relatively increased. . For this reason, it is possible to further widen the selection range of the shape and size of the model formed by the discharged contents.

(A) is a figure explaining the situation which discharges a content from the discharge cap shown in FIG. 1, and (b) is a figure explaining the state which discharges a content from the discharge cap of a modification. It is a figure explaining the discharge container using the conventional discharge cap, (a) is a top view of this discharge cap, (b) is a sectional view of the discharge container using this discharge cap, (c) () Is a diagram for explaining the situation of discharging the contents from the discharge container in (b).

  Hereinafter, an embodiment of a discharge container according to the present invention will be described with reference to the drawings. In the following description, for convenience, as shown in FIG. 1B, the side where the top wall (reference numeral 7) of the discharge cap is located with respect to the mouth portion (reference numeral 5) of the container body is upward, and the opposite side is referred to. The description will be made below.

  The discharge container 1 of the present embodiment includes a container body 2 and a discharge cap 3 as shown in FIG.

  The container body 2 is formed in a substantially bottle shape, and includes a body (not shown) having a bottomed cylindrical shape, and a shoulder 4 connected to an upper end of the body and having a diameter reduced upward. It has a cylindrical mouth 5 connected to the upper end of the shoulder 4, and a filling space S for accommodating contents therein is provided inside the body, the shoulder 4, and the mouth 5. Here, the body has flexibility and can be squeezed radially inward. A projection 6 is provided on the outer peripheral surface of the mouth 5.

  The discharge cap 3 covers the upper part of the mouth 5 and includes a disk-shaped top wall 7 having a center on the central axis C1 of the container body 2. The top wall 7 of the present embodiment has an upper surface formed in a planar shape, while a lower surface is formed in a convex shape bulging downward (the central portion bulges most). In other words, the top wall 7 has the largest thickness at the portion where the central axis C1 of the container body 2 passes, and becomes thinner toward the outer edge.

  A cylindrical peripheral wall 8 surrounding the mouth 5 is provided at an outer edge of the top wall 7, and a claw 9 engaging with the projection 6 is provided at a lower end of the peripheral wall 8. As a result, the discharge cap 3 is attached to the mouth 5 so as not to come out. When attaching the discharge cap 3 to the mouth 5, a male thread may be provided on the mouth 5, and a female thread may be provided on the peripheral wall 8, and the two may be screwed together. An external thread 10 is provided on the outer peripheral surface of the peripheral wall 8. The external thread portion 10 is provided for the purpose of attaching a cover cap (not shown) that covers the discharge cap 3. A cylindrical seal wall 11 is provided inside the peripheral wall 8 to be in contact with the inner peripheral surface of the mouth 5.

  The ceiling wall 7 is provided with a plurality of discharge ports 12 penetrating therethrough. The discharge port 12 includes an innermost discharge port 13 provided at a position closest to the central axis C1 of the container body 2 and an outer discharge port 14 excluding the innermost discharge port 13. In this embodiment, a total of three innermost discharge ports 13 are provided at equal intervals around the central axis C1. Further, the outer outlets 14 are located on the side away from the center axis C1 with respect to the innermost outlet 13 and a total of six first outer outlets 15 provided at equal intervals around the center axis C1; A second outer discharge port 16 which is located on the side away from the central axis C1 with respect to the discharge port 15 and is provided with a total of eight at equal intervals around the central axis C1, and a central axis C1 with respect to the second outer discharge port 16; And a third outer discharge port 17 provided in total 12 at equal intervals around the center axis C <b> 1. The innermost discharge port 13, the first outer discharge port 15, the second outer discharge port 16, and the third outer discharge port 17 are all circular holes, and all have the same outer diameter. The depth of the innermost discharge port 13 is the deepest, and the depth is smaller in the order of the first outer discharge port 15, the second outer discharge port 16, and the third outer discharge port 17.

  When the filling space S is pressurized by squeezing the body of the container main body 2 in the discharge container 1 of the present embodiment having such a configuration, the contents of the filling space S are discharged to the outside through the discharge port 12. Discharged. Here, when the outer diameter and the depth of the discharge ports are all the same as in the above-described conventional discharge container, the amount of the content discharged from each discharge port is provided at a location close to the central axis of the container body. The largest number is from the discharge port, and it tends to decrease as the distance from the center axis increases. However, in the present embodiment, the depth of the innermost discharge port 13 provided closest to the center axis C1 is the deepest. In addition, the flow resistance when the contents are discharged becomes the largest. In addition, the depth of the first outer discharge port 15, the second outer discharge port 16, and the third outer discharge port 17 becomes smaller in the order away from the central axis C1 toward the outside in the radial direction. For this reason, according to the discharge container 1 of the present embodiment, as shown in FIG. 2A, the amounts of the contents discharged from the discharge ports 12 can be made uniform.

  Note that the discharge container of the present invention is not intended only to equalize the amount discharged from each of the discharge ports. For example, in the case where the tendency is opposite to that of the discharge state in the conventional discharge container (the discharge amount from the innermost discharge port is small, and the discharge amount from the outer discharge port is large), conventionally, the outside of the outer discharge port is used. However, as shown in FIG. 2B, if a top wall 7 ′ whose lower surface swells downward from the top wall 7 as shown in FIG. Since the flow resistance can be increased by further increasing the depth, this discharge state can be realized. In addition, the thickness of the top wall 7 'may be locally changed, and thereby, the discharge amount of the content discharged on the upper surface of the top wall 7' can be partially changed.

  In the above-described embodiment, the outer diameters of the innermost discharge port 13, the first outer discharge port 15, the second outer discharge port 16, and the third outer discharge port 17 are all equal and the depth is changed. The outer diameter of the first outer discharge port 15, the second outer discharge port 16, and the third outer discharge port 17 may be made larger than the outer diameter of the discharge port 13, and then the depth may be changed. Further, the shape of the innermost discharge port 13, the first outer discharge port 15, the second outer discharge port 16, and the third outer discharge port 17 is not limited to a circular shape, and may be an elliptical or polygonal hole. It may extend, or may extend in a curved or bent shape. Further, the innermost discharge port 13, the first outer discharge port 15, the second outer discharge port 16, and the third outer discharge port 17 may be independent holes or may be connected by a slit or the like. In addition, although it depends on the shape of the molded article, in consideration of the balance of the content to be discharged, the outer diameters of the first outer discharge port 15, the second outer discharge port 16, and the third outer discharge port 17 (in the case of a long hole, (Minimum width) is preferably equal to or more than the outer diameter (minimum width) of the innermost ejection port 13 and equal to or less than twice the outer diameter. Considering that the discharge cap 3 is formed by a mold, the outer diameter (minimum width) of the innermost discharge port 13 is preferably 0.3 mm or more in terms of moldability and mold strength. The container main body 2 is not limited to a bottle-shaped one, and may be, for example, a tube-shaped one. The means for discharging the contents from the container main body 2 is not limited to the means for squeezing the container main body 2, but may be a means using a pump or a pressurized medium (aerosol). Also, various contents can be used. For example, the contents may be discharged in a gel shape, a foam shape, or a paste shape.
