  By the way, in such a pump container with a saucer, depending on whether a finger is applied or not, the spout is clogged with a finger, so that the contents may be poured out from the narrowed spout. . In particular, in the case where the spout is located immediately above the outlet opening of the stem, as shown in Patent Document 1, the content discharged from the outlet opening of the stem is almost reduced in flow momentum. Since it goes to the pouring outlet without any problem, the phenomenon in which the contents are poured out vigorously tends to occur. Under such circumstances, for example, when using a relatively rough and thin application tool, the contents may pass through the application tool and scatter around.

  An object of the present invention is to solve such a problem, and an object of the present invention is to propose a novel pump container with a saucer capable of gently pouring the contents.

  The present invention provides a pump that is attached to the mouth of a container body and sucks the contents contained in the container body by repeated pushing and returning operations of the stem, and is attached to the stem and fed from the pump. A pump container with a saucer having a spout for the contents to be discharged, wherein the saucer has a communication port that leads to an outlet opening of the stem and is held by the stem, and the spout And an upper passage having a top wall that folds the contents of the internal passage around the outer periphery and leads to the spout. It is a pump container with a saucer characterized by including a tray.

  Moreover, it is preferable that at least one of the lower plate and the upper plate has a groove that abuts against the other plate to form the internal passage.

  Moreover, it is preferable that the said outer peripheral part has the inner surface of the substantially circular arc which connects the said internal channel | path and the said spout smoothly.

  Moreover, it is preferable to provide a plurality of the spouts at the same radial position of the upper plate.

  Moreover, it is preferable that the said spout is provided adjacent to the inner peripheral side of the said outer peripheral part, and is opened toward the inner peripheral direction of the said top plate.

  Moreover, it is preferable that the said saucer has a cover body which covers the said upper plate, and a hinge which connects this cover body and this upper plate.

  The saucer of the present invention forms a lower plate having a communication port leading to the outlet opening of the stem and an inner passage for guiding the contents from the communication port between the lower plate and the contents of the inner passage at the outer peripheral portion. And a top plate having a top wall that is folded back to lead to the spout. As a result, the contents fed from the outlet opening of the stem are detoured in the internal passage, and are poured out after being folded at the outer peripheral portion, so that the momentum of the flow is weakened. For this reason, the contents can be slowly poured out from the spout.

  Further, by providing the rib for forming the internal passage in the lower plate, the internal passage can be provided with high accuracy without increasing the number of parts.

  Further, by forming a substantially arc surface shape that smoothly connects the internal passage and the spout at the outer peripheral portion, the contents guided to the outer peripheral portion can be poured out from the spout without stagnation. .

  Further, by providing a plurality of spouts at the same radial position of the upper plate, the contents can be poured out from the upper plate without deviation.

  In addition, the outlet is provided adjacent to the inner peripheral side of the outer peripheral portion, and the contents are poured out from the outer periphery toward the center by opening toward the inner peripheral direction of the upper plate, so the outer peripheral side There is no risk of splashing.

  Moreover, since the tray has a lid that covers the upper pan and a hinge that connects the lid and the upper pan, the spout and the lid can be integrally formed, and the container can be manufactured at low cost. it can.

Can be in a state.

  As shown in FIGS. 4 and 5, the upper surface of the lower curved wall 51 is in contact with the lower surface of the top wall 61 described later. On the upper surface of the lower curved wall 51, twelve passage grooves 55 are formed radially from the center toward the outer periphery at regular angular intervals as shown in FIG. Of the upper surface of the lower curved wall 51, a portion other than the passage groove 55 comes into contact with the lower surface of the top wall 61, so that the space between the lower curved wall 51 of the lower plate 50 and the top wall 61 of the upper plate 60. An internal passage N is formed at the bottom. That is, the internal passage N is formed in a space in the passage groove 55 sandwiched between the lower curved wall 51 and the top wall 61.

  The upper plate 60 includes a top wall 61 that is concave toward the upper surface and covers the communication port 51a with an interval. A central portion of the bottom surface of the top wall 61 is provided with a connecting convex portion 61a that has a stepped cylindrical shape with an expanded lower portion and engages with the connecting rib 51b.

  The top wall 61 has an arcuate curved surface that is offset from the lower curved wall 51, and a portion other than the passage groove 55 of the lower curved wall 51 abuts the top wall 61, so that from the center to the outer periphery. An internal passage N having a substantially constant height is formed.

  Further, as shown in FIG. 4, the top wall 61 has a substantially arcuate inner side surface 64 at the outer peripheral portion 63. With this configuration, the contents from the inner passage N are folded back at the outer peripheral portion 63, and will be described later. Can lead to outlet 62.

  The internal passage N, the substantially arcuate inner surface 64, and the spout 62 are connected so that the curvature changes smoothly. That is, as shown in FIGS. 4 and 5, the inner surface 64 of the substantially arc has an introduction surface 64a, an arc surface 64b, and a lead-out surface 64c.

  The introduction surface 64a is a portion that bridges the internal passage N and the arc surface 64b, and is a surface having a curvature between the curvature of the lower curved wall 51 and the curvature of the arc surface 64b.

  The arc surface 64 b is a surface having a substantially arc shape, and has a function of folding the contents from the internal passage N and guiding them to the spout 62.

  The lead-out surface 64c is a portion that bridges the arc surface 64b and the spout 62, and is a surface having a curvature smaller than the curvature of the arc surface 64b.

  As shown in FIG. 5, the spout 62 is provided adjacent to the inner peripheral side of the outer peripheral portion 63 on the upper surface of the upper plate 60. As shown in FIG. 3, the spouts 62 are provided at equal intervals around the connecting convex portion 61 a. In other words, the spout 62 is provided at four positions on the same circumference of the upper plate 60 at an angular interval of 90 degrees. Moreover, the spout 62 is opened toward the inner peripheral direction as can be seen from FIG. In addition, the spout 62 may be one place and may be provided in two or more arbitrary plural places. Further, as shown in FIG. 3, the spout 62 is preferably disposed at a position on the circumference avoiding the passage groove 55.

  The lid body 70 includes a top wall 71 having a disk shape and a peripheral wall 72 depending from the edge of the top wall 71. The peripheral wall 72 is provided with a finger hooking portion 73 that protrudes radially outward and forms an arc shape on the opposite side of the hinge 42 across the central axis of the top wall 71.

  In order to pour the contents from the saucer-equipped pump container having such a configuration, the lid 70 is opened and the saucer 40 is rotated so that the stopper rib 54 is positioned at the short notch 37b (pump 20 From the state in which the driving of the pump 20 is impossible) to the state in which the stopper rib 54 is positioned in the longitudinal notch 37a (a state in which the driving of the pump 20 is allowed).

  Then, an application tool such as cotton or puff is placed on the upper plate 60, and the upper plate 60 is pressed so as to press the application device with a finger. As a result, the stem 26 is lowered to drive the pump 20, and the contents are fed from the outlet opening 26 a to the communication port 51 a and reach the outer peripheral portion 63 via the internal passage N. Then, the contents are further folded at the inner surface 64 of the substantially arc in the outer peripheral portion 63, moved on the circumference from the position of the passage groove 55 to the position of the spout 62, and poured out from the spout 62. In other words, the contents discharged from the outlet opening 26a bypass the inner passage N in the outer peripheral direction, are folded back at the outer peripheral portion 63, and are discharged after detouring so as to move on the circumference. Accordingly, since the flow momentum is weakened in multiple stages, the contents can be slowly poured out. In addition, since a plurality of spouts 62 are provided at the same radial position, the contents are poured out evenly, and the contents can be poured out more gently.

  Since the internal passage N is formed by the passage groove 55 provided in the lower plate 50, the internal passage N can be provided with high accuracy without increasing the number of parts.

  Moreover, since the outer peripheral part 63 has the substantially circular inner side surface 64 which connects the internal channel | path N and the spout 62 smoothly, it pours out from the spout 62, without retaining the content guide | induced to the outer peripheral part 63 can do.

  Moreover, since the spout 62 is directed and opened in the inner peripheral direction of the upper plate 60, the content is poured out from the outer periphery toward the center, and there is no possibility of scattering to the outer peripheral side.

  Further, since the upper plate 60 and the lid 70 are connected by the hinge 42, the spout 62 and the lid 70 can be integrally molded, and the container can be manufactured at low cost.

  In addition, the pump container with a saucer according to this invention is not limited to embodiment mentioned above, A various change is possible in the range according to a claim. For example, a passage groove for forming the internal passage N may be provided in the upper plate 60, and a portion other than the passage groove may be in contact with the lower curved wall 51. Further, a passage groove may be provided in both the lower plate 50 and the upper plate 60, and portions other than the passage groove may be in contact with each other. In addition, the configuration for switching between driving and non-driving of the pump 20 is not limited to the combination of the notch portion 37 and the stopper rib 54 as in the present embodiment, and various types that can switch the tray 40 to be depressible or impossible. Configuration can be applied.

  According to the present invention, since the contents can be slowly poured out, a new pump with a saucer that can prevent the trouble that the poured out contents pass through the applicator and scatter around the surroundings. A container can be provided.
