  However, the above-mentioned pouring cap has a concentric inner cylinder inside the outer cylinder of the inner plug (exterior wall of the exterior member), and a container in an annular recess formed between the inner cylinder and the outer cylinder. While fitting a mouth part and attaching to a container mouth part, it is only what hold | maintains the fixed cylinder of a flow volume adjustment tool firmly by the deformation | transformation of the inner cylinder at the time of this fitting.

  That is, the conventional pouring cap is merely a structure in which the interior member is held by the inner cylinder provided on the exterior member.

  For this reason, it is conceivable that the interior member is assembled in a state of being inclined with respect to the exterior member, and therefore, there is a complexity that extra care must be taken in the assembly operation. In addition, when the interior member is assembled in a state of being inclined with respect to the exterior member, it may be considered that accurate quantitative dispensing cannot be performed.

  Further, in order to remove such an improperly assembled cap, it is necessary to pay more attention to product inspection, and product inspection becomes complicated.

  Furthermore, according to the above conventional structure, the interior member is only held by the inner cylinder of the exterior member, so that the exterior member and the interior member are separated by a slight deformation or a slight impact accompanying a temperature change. There is no denying the possibility of it. For this reason, such conventional caps must pay more attention to handling during storage and transport than simple caps and metering taps.

  The object of the present invention is to provide an exterior member that can be unplugged at the time of use, and an interior member that enables quantitative dispensing after unplugging, has excellent workability during assembly, has a low defect rate, and is distributed. The object is to provide a dispensing cap that is relatively easy to handle in stages.

  The pouring cap according to the present invention has an exterior wall that is locked to the outside of the mouth portion of the container, and a ceiling wall that is connected to the exterior wall and seals the upper end opening of the mouth portion. A pour-out hole was formed in a tubular part that had an exterior member in which a stopper part was formed by the formed thin-walled line and a partition wall that partitioned a passage formed inside the mouth part, and was bulged from the partition wall. The pouring cap comprising an interior member and a combination of the interior member and the exterior member, wherein the interior member includes an interior wall that rises from the outer edge of the partition wall along the inner surface of the mouth portion, and an exterior wall from the interior wall. The outer member has a flange that spreads in the direction and can be in close contact with the upper end of the mouth portion, and a projecting wall that stands up from the flange. The exterior member has a projection that sandwiches the flange together with the top wall on the exterior wall. The wall has a recess into which the protruding wall is fitted. That.

  In the present invention, it is preferable that the stopper portion has a shape that opens the entire partition wall to the outside.

  According to the present invention, an interior wall is erected on the partition wall of the interior member along the inner surface of the mouth portion, and a flange extending outward is provided on the interior wall, and the flange is provided on the top wall and the exterior wall of the exterior member. Therefore, the interior member can be assembled accurately without being tilted by a simple operation of hooking and holding the lower end of the flange on the protrusion provided on the exterior member.

  In addition, according to the present invention, the product can be easily inspected because it can be accurately assembled without tilting the interior member.

  Furthermore, since the flange of the interior member is sandwiched between the top wall of the exterior member and the protrusion provided on the exterior wall, the present invention does not separate by minute deformation or slight impact due to temperature change. The handling at the time is the same as that of a simple plug-type cap or a metering tap.

  In addition, according to the present invention, since the top wall of the exterior member has a recess in which the protruding wall is fitted, the interior member can be further removed by a simple operation of fitting the protruding wall of the interior member into the recessed portion of the exterior member. It can be assembled accurately and firmly. In addition, the projecting wall of the interior member and the recess of the exterior member also function as a guide for assembling the interior member to the exterior member, so that workability during assembly is further improved.

  Therefore, according to the present invention, it is provided with an exterior member that can be unplugged at the time of use, and an interior member that enables quantitative dispensing after unplugging, has excellent workability during assembly, has a low defect rate, and is in a distribution stage. A dispensing cap that is relatively easy to handle can be provided.

  In the present invention, various shapes can be selected as the shape of the unplugging part. In particular, if the shape that opens the entire partition wall to the outside is selected, the top wall remaining after unplugging is poured out. Since the introduction of outside air into the hole is not hindered, the replacement of air at the time of pouring becomes good, so that smooth pouring can be realized.

  Further, according to the present invention, since the interior member has a flange that can be in close contact with the upper end of the mouth of the container, the exterior member can be assembled separately after the interior member is assembled to the container. That is, according to the present invention, it is possible not only to assemble the dispensing cap to the container, but also to assemble the member to the container and to provide the dispensing cap as a result.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is an exploded perspective view showing a dispensing cap 100 according to one embodiment of the present invention in a state where it is disassembled into an exterior member 110 and an interior member 120 which are components thereof. FIG. 2 is a cross-sectional view of the principal part showing a state in which the pouring cap 100 is attached to the mouth portion 210 of the container 200 in a vertical cross section passing through the bottle axis O, and FIG. FIG.

  Reference numeral 110 denotes a synthetic resin exterior member that forms the external shape of the pouring cap 100.

  As shown in FIG. 2, the exterior member 110 surrounds the mouth portion (hereinafter referred to as “container mouth portion”) 210 of the container 200 around the axis O and is locked to the outside of the container mouth portion 210. It has a wall 111. When the outer wall 111 is locked to the container mouth part 210, the inner surface of the outer wall 111 is provided with a locking protrusion 112 that is hooked by an annular bulging part 211 provided at the upper edge of the container mouth part 210.

  A ceiling wall 113 that covers the upper end opening of the container mouth portion 210 is integrally connected to the exterior wall 111.

  The top wall 113 seals the upper end opening of the container mouth portion 210. The top wall 113 is formed with a thin line L that can be broken. This line L forms the plug part P shown in FIG. Further, the top wall 113 is integrally formed with a pull ring 114a via a base portion 114b at an upper portion of a region where the stopper portion P is formed. As a result, when the user hooks and pulls the finger on the pull ring 114a, the line L formed on the top wall 113 is broken, and only the plug portion P is removed, thereby forming an opening on the top wall 113.

  The lid 115 is connected to the exterior wall 111 via the hinge 116. As a result, the lid 115 opens and closes the upper part of the top wall 113 with the hinge 116 as a base point.

  Thereby, the exterior member 110 can be integrally molded using a synthetic resin or the like as a raw material.

  Reference numeral 120 denotes an interior member that is integrally assembled to the exterior member 110.

  The interior member 120 has a partition wall 121 that partitions a passage 220 formed inside the container mouth portion 210. As shown in FIG. 1, the partition wall 121 has a cylindrical portion 121a bulged from the partition wall 121, and a plurality of extraction holes A1 are formed in the side wall. The partition wall 121 has an annular flat surface portion 121b surrounding the cylindrical portion 121a, and a plurality of outside air introduction holes A2 are formed in the flat surface portion 121b.

  The partition wall 121 is integrally connected with a cylindrical interior wall 122 that rises from the outer edge of the partition wall 121 along the inner surface 210f of the container mouth portion 210. When the interior wall 122 is attached to the container mouth portion 210, the inner wall 122 is in close contact with the inner surface 210f of the container mouth portion 210 as shown in FIG.

  An annular flange 123 extending outward from the upper end of the interior wall 122 is integrally connected to the interior wall 122. When the flange 123 is attached to the container mouth portion 210, the flange 123 is in close contact with the upper end 212 of the container mouth portion 210 as shown in FIG.

  As shown in FIG. 1, an annular projecting wall 124 standing from the flange 123 is integrally connected to the flange 123.

  As a result, the interior member 120 can also be integrally molded using a synthetic resin or the like as a raw material.

  Here, as shown in FIG. 2, the exterior member 110 has a holding surface 113 f that holds the upper end of the flange 123 on the top wall 113. In addition, the exterior wall 111 is integrally provided with a protrusion 117 that holds the lower end of the flange 123. That is, the interior member 120 is accurately assembled without being inclined with respect to the exterior member 110 because the flange 123 is sandwiched between the holding surface 113f of the exterior member 110 and the protrusion 117. The protrusion 117 can be formed intermittently along the entire circumference of the exterior wall 111 or along the circumferential direction thereof.

  In addition, the exterior member 110 has an annular recess 118 in the top wall 113 in which the protruding wall 124 of the interior member 120 is fitted. In this case, the protruding wall 124 of the interior member 120 and the recess 118 of the exterior member 110 function as a guide for assembling the interior member 120 to the exterior member 110 in addition to assembling the interior member 120 accurately and firmly. The protruding wall 124 and the recess 118 can be formed over the entire circumference of the exterior wall 111 or the interior wall 122.

  That is, the dispensing cap 100 combines the exterior member 110 that can be unplugged at the time of use with the interior member 120 that enables quantitative dispensing after unplugging, thereby maintaining the quality of contents and quantitative dispensing after unplugging. It is established as one independent cap that can achieve both.

  The dispensing cap 100 has a partition wall 121 of the interior member 120 with an interior wall 122 standing along the inner surface 210f of the container mouth portion 210, and a flange 123 extending outwardly on the interior wall 122. Since the top wall 113 of the member 110 is clamped by the projection 117 provided on the exterior wall 111, the interior member 120 can be obtained by a simple operation of hooking and holding the lower end of the flange 123 on the projection 117 provided on the exterior member 110. Can be assembled accurately without tilting.

  In addition, according to such a configuration, the interior member 120 can be accurately assembled without being inclined, so that product inspection is also simplified.

  Further, in this embodiment, the flange 123 of the interior member 120 is sandwiched between the top wall 113 of the exterior member 110 and the projection 117 provided on the exterior wall 111, so that it is not separated by a minute deformation or a slight impact accompanying a temperature change. Therefore, handling at the time of storage and transportation can be the same as that of a simple cap and quantitative dispensing tap.

  In addition, as in this embodiment, if the top wall 113 of the exterior member 110 has a recess 118 in which the projecting wall 124 is fitted, the projecting wall 124 of the interior member 120 is only fitted in the recess 118 of the exterior member 110. With this simple operation, the interior member 120 can be assembled more accurately and firmly. Further, the projecting wall 124 of the interior member 120 and the recess 118 of the exterior member 110 also function as a guide for assembling the interior member 120 to the exterior member 110, so that workability at the time of assembly is further improved.

  Therefore, according to this embodiment, the exterior member 110 that can be unplugged at the time of use, and the interior member 120 that enables quantitative dispensing after unplugging, has excellent workability during assembly, and has a low defect rate, A dispensing cap that is relatively easy to handle in the distribution stage can be provided.

  In the present invention, various shapes can be selected as the shape of the unplugging part P. In particular, if a shape that opens the entire partition wall 121 to the outside is selected, the ceiling wall 121 remaining after unplugging is selected. Does not hinder the introduction of the outside air into the outside air introduction hole A2, so that the air replacement at the time of pouring becomes good, so that smooth pouring can be realized.

  Further, in the present invention, since the interior member 120 has the flange 123 that can be in close contact with the upper end of the container mouth portion 210, the exterior member 110 can be assembled separately after the interior member 120 is assembled to the container 200. In other words, according to the present invention, it is possible not only to assemble the dispensing cap 100 to the container 200 but also to assemble the interior member 120 and the exterior member 110 to the container 200 and provide the dispensing cap 100 as a result.

  The above is a preferred embodiment of the present invention, but various modifications can be made within the scope of the claims. For example, the lid 115 of the exterior member 110 is not limited to a hinge cap but may be a screw cap or the like.
