A seal cylinder that is in contact with the extraction cylinder portion from the inside in a state of being covered with the cap main body and forms a seal portion over the entire circumference with the extraction cylinder portion; and A pouring cap provided with a lid body that respectively suspends an annular side wall that surrounds the top wall from the top wall, the tip of the pouring tube portion being widened from the upper end of the seal portion, and the pouring tube portion A circumferential groove and a liquid reservoir connected to the circumferential groove are formed between the seal cylinders, and the seal cylinder and the annular side wall of the outer peripheral surface of the seal cylinder and the back side surface of the top wall When the annular surface formed between each is composed of a mirror skin Moni, the inner peripheral surface of the annular side wall is characterized in that is constituted by grain skin.

  In the pouring cap having such a configuration, the tip of the pouring tube portion is widened from the upper end of the seal portion, and the cap body is covered with a lid body, and between the pouring tube portion and the seal tube. Since the circumferential groove and the liquid reservoir connected to the circumferential groove are formed, for example, the inner solution adhered to the tip of the dispensing cylinder when the inner solution is poured out does not return completely into the container. Even when the lid is closed, the content liquid adhering to the tip of the dispensing cylinder part is accumulated in the liquid reservoir through a circumferential groove formed between the outer peripheral surface of the seal cylinder and the inner peripheral surface of the dispensing cylinder part. It is done. At this time, since the outer peripheral surface of the seal cylinder and the annular surface of the top wall were configured with mirror skin, the inner solution adhering to the outer peripheral surface of the seal cylinder and the annular surface of the top wall was smoothly guided to the liquid reservoir, On the other hand, since the inner peripheral surface of the annular side wall is formed with a textured surface, when the content liquid adheres to the inner peripheral surface of the annular side wall, the attached inner solution can be made difficult to drip. When the lid is opened again, the internal solution stored in the liquid storage part flows down along the inner surface of the dispensing cylinder part and is returned to the container.

  Therefore, according to this dispensing cap, even if the internal solution adheres to the outside of the seal cylinder of the lid, the adhered internal solution can be reliably returned to the container, so that the internal solution is externally exposed when the lid is opened. Never leak out.

  In the pouring cap of the present invention, it is preferable that the circumferential groove is formed in a downward gradient toward the liquid reservoir, and according to this, the inner solution that has entered the circumferential groove is removed. It can be more reliably and smoothly guided to the liquid reservoir.

  In the pouring cap according to the present invention, the cap body and the lid body are connected via a hinge, and the liquid reservoir is disposed on the rear side where the hinge is provided. According to this, it is possible to reliably capture and return the liquid content dropped from the seal cylinder while the lid is opened.

  Moreover, in the dispensing cap of the present invention, it is preferable that the annular surface is formed in a downward slope toward the outer peripheral surface of the seal cylinder, and according to this, the inner solution adheres to the annular surface. In this case, the inner solution can flow down toward the outer peripheral surface of the seal cylinder, and as a result, can be led to the liquid reservoir and returned to the container when the lid is opened.

  According to the present invention, it is possible to easily collect the internal solution adhering to the outside of the sealing cylinder of the lid body into the container, and to provide a dispensing cap that does not leak to the outside when the lid is opened.

FIG. 1 is a cross-sectional view along the axial direction of a dispensing cap according to an embodiment of the present invention. In the figure, reference numeral 1 represents a dispensing cap, and reference numeral C represents a mouth of a container. Yes.

  As shown in FIG. 1, the pouring cap 1 is a cap body 3 and a lid 5 that are integrally connected to each other on the rear side via a hinge 7 so as to be freely opened and closed. Although it can be performed from the front side facing the hinge 7, the cap body 3 and the lid 5 may be detachably connected via a screw.

  The cap body 3 includes a top plate 9, an outer wall 11 that hangs down from the periphery of the top plate 9 and undercuts (fittings) from the outside to the mouth C of the container, and a mouth of the container that hangs down from the top plate 9. An inner wall 13 which is inserted into C and engages closely; a pouring cylinder portion 15 which stands up around the pouring opening and guides the pouring of the internal solution; and an outer side of the pouring cylinder portion 15 And an annular projecting wall 17 that is fitted to the lid body 5 and maintains its closed posture in a state in which the lid body 5 is closed. Further, the pouring opening of the cap body 3 is sealed by a sealing wall 19 that is integrally formed inside the pouring cylinder portion 15 and can be torn off along a single scheduled fracture groove m. Is provided with a pull ring 21 via a support column 20. Note that the discharge opening may be sealed with a sealing member (not shown) instead of the sealing wall 19 that is torn off by the pull ring 21 being caused.

  The lid 5 hangs from the top wall 23 and the top wall 23, and abuts (fits) the pour cylinder portion 15 from the inside with the lid 5 covered on the cap body 3. A seal cylinder 24 that forms a seal portion S over the entire circumference with the outlet cylinder portion 15, and an annular side wall 26 that hangs down from the periphery of the top wall 23 and surrounds the seal cylinder 24. The Further, an annular surface 23 a formed between the seal cylinder 24 and the annular side wall 26 on the back side surface of the top wall 23 is formed so as to descend toward the outer peripheral surface 24 a of the seal cylinder 24.

  And in the pouring cap 1 according to the present invention, the tip of the pouring tube portion 15 is expanded from the seal portion upper end S1, and the amount of expansion is locally increased on the rear end side (hinge side). A liquid having a width (W1 <W2) wider than the circumferential groove 28 connected to the circumferential groove 28 and the circumferential groove 28 between the dispensing cylinder portion 15 and the seal cylinder 24 in a state where the lid 5 is put on the cap body 3. Each of the reservoirs 30 is formed, and the outer peripheral surface 24a and the annular surface 23a of the seal cylinder 24 are each configured with a mirror surface, and the inner peripheral surface 26a of the annular side wall 26 is configured with a textured (uneven) skin. . Here, the specular skin can be formed by a known specular finishing process, and the embossed skin can be formed by a known embossing process. The surface roughness (arithmetic average roughness (Ra)) of wrinkle skin is larger than the surface roughness (arithmetic average roughness (Ra)) of specular skin.

  The liquid reservoir 30 is preferably provided on the side opposite to the dispensing side of the dispensing cap 1, and the “pouring side” here refers to the dispensing opening or the dispensing cylinder 15 having an irregular shape. When the direction that is easy to pour out is specified, the direction is the pour side, and when the cap body 3 and the lid 5 are connected via the hinge 7 as in this embodiment, the hinge The front side that faces is the extraction side. Therefore, in this embodiment, the liquid pool part 30 is arrange | positioned at the back side of the extraction | pouring cap 1 which is the side in which the hinge 7 is located. The circumferential groove 28 continuously extends from one end of the liquid reservoir 30 to the other end of the liquid reservoir 30 via the front side of the dispensing cap 1. Furthermore, the circumferential groove 28 is formed in a downward gradient toward the liquid reservoir 30 (θ> 0). In the figure, reference numeral 32 denotes a lip provided on the front surface side of the lid 5, and reference numeral 34 denotes a lip provided on the front surface side of the cap body 3, and accommodates the lip 32 with the lid 5 closed. A lip receiving groove.

  The pouring cap 1 having the above-described configuration is such that the tip of the pouring tube portion 15 is expanded from the seal portion upper end S1 and the amount of expansion is locally increased on the rear side. Since the circumferential groove 28 and the liquid reservoir 30 connected to the circumferential groove are formed between the seal cylinders 24, respectively, for example, as shown in FIG. Even if the lid 5 is closed while the inner solution attached to the tip of the portion 15 does not completely return to the container, the liquid content attached to the tip of the dispensing cylinder 15 will remain on the outer peripheral surface of the seal cylinder 24 and the dispensing cylinder. The liquid is stored in the liquid reservoir 30 through a circumferential groove 28 formed between the inner peripheral surface of the portion 15.
