  As shown in FIGS. 1 to 4, the spout assembly 1 according to the present embodiment includes a cylindrical spout body 10 having a flange 13 as a mounting portion at a lower end portion, and an upper end of the spout body 10. A cap 30 having a cylindrical shape to be closed and a cylindrical slide member 50 accommodated in the inside of the spout main body 10 on the inner peripheral surface side are provided. The spout main body 10 is connected to the inner peripheral surface via a thin portion 17 that can be broken, and has a closing portion 18 that closes a lower side than the slide member 50. The cap 30 has a central cylindrical body 37 that is inserted into the slide member 50. As will be described in detail later, in the spout assembly 1, the cap 30 is rotated in the opening direction, so that the slide member 50 moves downward with respect to the spout body 10 and the thin portion 17 is broken. The initial opening is configured.

  As shown in FIGS. 4 to 7, the cylindrical spout body 10 is a content spout and a drinking mouth, and has a circular opening 11 at the upper end and a screw 12 on the outer peripheral surface. . Here, FIG. 6 is a plan view of the spout body 10 of the spout assembly 1 of FIG. 1, and FIG. 7 is a cross-sectional view taken along the line VII-VII of FIG. In addition, the VII-VII line in FIG. 6 is a straight line which passes along the axis | shaft of the cylindrical spout main body 10, and FIG. 6 is a vertical sectional view of the spout main body 10 by which the cross section similar to FIG. 4 was shown. In FIG. 6, the closing direction d1 and the opening direction d2 of the cap 30 are indicated by arrows. The male screw 12 engages with the female screw 34 of the cap 30, and the cap 30 is attached to the spout main body 10 without loosening by the engagement of the screw. The male screw 12 is a right-hand screw, and the clockwise rotation direction in a plan view is the closing direction d1 of the cap 30, and the counterclockwise direction is the opening direction d2. The male screw 12 and the female screw 34 may be any shape as long as the cap 30 can be attached to the spout main body 10 without loosening. The shape may be a single-threaded screw or a multi-threaded screw such as a double-threaded screw or a triple-threaded screw. It may be. Further, in a plan view, a winding angle that is an angle that circulates from one end of the external thread 12 to the other end can be appropriately designed, and the internal thread 34 of the cap 30 is also the same.

  The spout main body 10 has a plate-like flange 13 protruding outward from the outer peripheral surface at the lower end portion and having a substantially circular outer shape in plan view. The flange 13 has a flange base portion 14 that is formed to have a thicker wall thickness upward, and is connected to the spout main body 10 via the flange base portion 14. That is, the flange 13 is improved in strength of the connecting portion with the spout main body 10 by the flange base 14. The flange base portion 14 has a substantially circular outer shape in plan view, and is formed in a shape corresponding to a hole formed in a container described later. Four claw portions 15 projecting outward are formed on the outer edge of the flange base portion 14. The claw portions 15 have a predetermined distance from the upper surface of the flange 13 and are arranged at substantially equal intervals in the circumferential direction in plan view. Further, the flange base portion 14 has a cylindrical cutout portion 16 in which the lower surface side is cut out upward over the entire circumference. The flange base portion 14 is configured so that a portion thicker than a predetermined thickness is not formed by the cutout portion 16, and the injection moldability is improved.

  In addition, the flange 13 as an attachment part is used for joining to the container of the spout union assembly 1, The shape is not limited to the above-mentioned shape, The container of the container to which the spout union assembly 1 is attached. It can design suitably according to a form.

  The lower end of the spout main body 10 is formed with a disk-shaped blocking portion 18 that is connected to the inner peripheral surface via a thin portion 17. More specifically, the disc-shaped closing portion 18 is connected to the inner peripheral surface of the spout main body 10 through the thin-walled portion 17 whose outer edge is a circular shape. The blocking portion 18 has a shape corresponding to the opening at the lower end of the spout main body 10. The cylindrical spout body 10 is configured such that the opening at the lower end is sealed by the closing portion 18, and the content is poured from the opening 11 at the upper end through the opening exposed when the thin portion 17 is broken. It becomes possible to come out.

  The thin portion 17 is formed with the same diameter as the opening at the lower end of the spout main body 10. As shown in FIG. 7, the thin portion 17 is formed so that the lower side is cut out in a substantially V shape in a cross-sectional view and the thickness in the vertical direction is reduced. That is, the thin-walled portion 17 is between the thin-walled edge portions 17a and 17b that gradually decrease in thickness outward and inward in the radial direction and the thin-walled edge portions 17a and 17b on the outer and inner sides. And a thin central portion 17c. And the thin part 17 formed in this thin thickness is comprised so that the thin center part 17c can be fractured | ruptured at the time of initial stage opening.

  The closing portion 18 is connected to the inner peripheral surface of the spout main body 10 via the thin portion 17 and seals the side of the spout main body 10 below the slide member 50, and the thin portion 17 at the time of initial opening. Any structure that can be broken is acceptable. For example, the thin-walled portion 17 may be formed such that the upper side is cut out in a substantially V shape in a cross-sectional view and the thickness in the vertical direction is reduced. Further, the thin portion 17 may be configured not to include the thin edge portions 17a and 17b whose thickness gradually decreases on the outer side and the inner side in the radial direction. That is, the thin portion 17 may be formed only from the thin central portion 17c. Further, the closing portion 18 only needs to be positioned on the lower side of the slide member 50. However, from the viewpoint of the initial opening property and productivity of the spout assembly 1, the closing portion 18 is preferably formed at the lower end of the spout body 10.

  Here, the lower surface of the closing portion 18 is preferably positioned slightly above the lower surface of the flange 13. With such a configuration, even when the lower surface of the flange 13 is placed as a grounding surface before being joined to the container, no force acts on the thin portion 17, There is no damage and it is easy to use during manufacture and transport.

  The thin-walled portion 17 has four protrusions 19 tapered on the lower surface side from the end on the closed portion 18 side outward in the radial direction, that is, toward the end on the spout body 10 side (see FIG. 3). ). In the thin portion 17, the radial width of the thin central portion 17 c is partially narrowed by the protrusion 19. The thin central portion 17c where the protrusions 19 are formed is thicker than other portions and has improved rigidity. The protrusions 19 are arranged at substantially equal intervals in the circumferential direction, and are formed corresponding to piercing portions 51 of the slide member 50 described later. In addition, the protrusion 19 should just be formed so that the radial direction width | variety of the thin center part 17c in the thin part 17 may be partially narrowed, for example, it is a diameter from the edge by the side of the spout main body 10 of the thin part 17. It may be formed to extend toward the end on the side of the closing portion 18 that is inward of the direction. Further, the thin portion 17 may be configured without the protrusion 19. However, from the viewpoint of the initial opening property of the spout assembly 1, it is preferable that the thin portion 17 has the protrusion 19 at a position corresponding to the piercing portion 51 of the slide member 50 in the circumferential direction. Furthermore, it is preferable that the protrusion 19 has a tapered shape from one of the end of the thin portion 17 on the closing portion 18 side and the end of the spout main body 10 toward the other.

  Moreover, the spout main body 10 has four main body guide portions 20 that protrude inward from the inner peripheral surface. The main body guide part 20 is formed corresponding to a guide part 53 of a slide member 50 described later. The main body guide portions 20 are arranged at substantially equal intervals in the circumferential direction, and extend from the upper portion of the spout main body 10 to the thin portion 17. More specifically, the lower end of the main body guide portion 20 is connected to the thin edge portion 17a in which the thickness on the outer peripheral side of the thin portion 17 gradually decreases. Further, in plan view, the inner side end, which is the tip of the main body guide portion 20, is located at the inner peripheral edge of the thin edge portion 17a, and the main body guide portion 20 is connected to the thin center portion 17c. Not done.

  The end surface of the main body guide portion 20 on the opening direction side and the inner peripheral surface of the spout main body 10 (through the joint portion between the end surface of the main body guide portion 20 on the opening direction side and the inner peripheral surface of the spout main body 10, The angle formed with the surface that contacts the inner peripheral surface of the main body 10 is an obtuse angle. On the other hand, the end face of the main body guide portion 20 in the closing direction and the inner peripheral surface of the spout main body 10 (through the joint portion between the end face of the main body guide portion 20 in the closing direction and the inner peripheral surface of the spout main body 10; The angle between the spout main body 10 and the inner peripheral surface of the spout main body 10 is substantially a right angle. The main body guide portion 20 does not engage with the guide portion 53 of the slide member 50 when the slide member 50 described later rotates in the closing direction inside the spout main body 10, and the slide member 50 When rotating in the opening direction, the shape and the configuration are not particularly limited as long as the rotation of the slide member 50 in the opening direction is restricted by engaging with the guide portion 53.

  The spout main body 10 has a main body engaging portion 21 that protrudes inward from the inner peripheral surface and extends in the circumferential direction. An end on the inner side, which is the tip of the main body engaging portion 21, is located outward from an end on the inner side of the main body guide portion 20. The main body engaging portion 21 is located at a predetermined interval from the upper surface of the closing portion 18 in the vertical direction. This space | interval respond | corresponds to the width | variety of the up-down direction of the guide part 53 of the slide member 50 mentioned later.

  Moreover, the spout main body 10 has an annular turnip 22 that protrudes outward from the outer peripheral surface below the external thread 12. The turnip 22 is located at a predetermined distance from the upper surface of the flange base 14. Four ratchet protrusions 23 are formed between the turnable 22 and the flange base 14 so as to protrude outward from the outer peripheral surface. The ratchet protrusion 23 is formed corresponding to a ratchet claw 41 included in the band 33 connected to the cap 30 described later.

  The end surface of the ratchet protrusion 23 on the opening direction side and the outer peripheral surface of the spout main body 10 (the outer periphery of the spout main body 10 passes through the joint portion between the end surface of the ratchet protrusion 23 on the opening direction side and the outer peripheral surface of the spout main body 10). The angle formed with the surface in contact with the surface is an obtuse angle. On the other hand, the end surface of the ratchet protrusion 23 on the plugging direction side and the outer peripheral surface of the spout main body 10 (through the joint between the end surface of the ratchet protrusion 23 on the plugging direction side and the outer peripheral surface of the spout main body 10) The angle formed with the surface that contacts the outer peripheral surface is an acute angle. The ratchet protrusion 23 does not engage with the ratchet claw 41 of the band 33 when the band 33 connected to the cap 30 described later rotates in the closing direction with respect to the spout main body 10. When the 33 rotates in the opening direction, it may be configured to engage with the ratchet pawl 41 to restrict the rotation of the band 33 in the opening direction, and the shape and configuration are not particularly limited.

  As shown in FIGS. 4, 8, and 9, the cap 30 includes a cylindrical outer wall portion 31 extending in the vertical direction and a disk-shaped top surface 32 that closes the upper end of the outer wall portion 31. , Formed in a cylindrical shape with a top. A cylindrical band 33 is connected to the lower side of the cap 30. 8 is a bottom view of the cap 30 of the spout assembly 1 in FIG. 1, and FIG. 9 is a cross-sectional view taken along the line IX-IX in FIG. 8 is a straight line passing through the axis of the cylindrical outer wall portion 31, and FIG. 8 is a vertical sectional view of the cap 30 showing the same cross section as that in FIG. 8 and 9, the closing direction d1 and the opening direction d2 of the cap 30 are indicated by arrows.

  A female screw 34 that meshes with the male screw 12 of the spout main body 10 is formed on the inner peripheral surface of the outer wall portion 31. The cap 30 is attached to the spout main body 10 without loosening by the engagement between the female screw 34 and the male screw 12. The cap 30 is attached to the spout main body 10 integrally with the connected band 33.

  A knurl 35 including a plurality of ribs extending in the vertical direction is formed on the outer peripheral surface of the outer wall portion 31. Since the cap 30 includes the knurl 35, when the cap 30 is attached to and detached from the spout main body 10, the finger is less likely to slip, and the attaching / detaching operation is facilitated. The knurling 35 may have a shape that functions as a slip stopper when the cap 30 is attached to and detached from the spout main body 10. In addition, as a structure of anti-slip | skid, the structure which provides the wrinkles formed by making the surface roughness of the outer peripheral surface of the outer wall part 31 rough instead of the knurling 35 may be sufficient.

  The top surface 32 has an annular inner ring 36 that extends downward from the inner surface and a cylindrical central cylinder 37 that extends downward from the inner surface. The annular inner ring 36 and the cylindrical central cylindrical body 37 are formed coaxially with the cylindrical outer wall portion 31, and the central cylindrical body 37 is located on the inner side of the inner ring 36. The cap 30 is configured to seal the opening 11 of the spout body 10 by the top surface 32 and the inner ring 36 when attached to the spout body 10. The inner ring 36 has an outer diameter larger than the inner diameter of the spout main body 10 and is tapered so that the outer peripheral surface of the tip portion is inclined inwardly downward. When the cap 30 is attached to the spout main body 10, the inner ring 36 is inserted into the inside from the opening 11 and is fitted to the spout main body 10. At this time, the inner ring 36 is bent inward, and the outer peripheral surface is in close contact with the inner peripheral surface of the spout main body 10 to seal the opening 11.

  The inner ring 36 only needs to have a shape that can seal the opening 11 of the spout main body 10, and can be appropriately designed according to the shape of the spout main body 10. Moreover, the structure which seals the opening 11 of the spout main body 10 is not limited to the structure by the inner ring 36. For example, when the cap 30 is attached to the spout main body 10 on the outer side of the inner ring 36, an annular closing ring that protrudes downward from the inner surface of the top surface 32 is further provided. You may comprise so that the opening 11 may be sealed by adhering to the outer peripheral surface of an upper end or an upper part.

  The central cylinder 37 is formed in a cylindrical shape coaxial with the cylindrical outer wall portion 31. When the cap 30 is attached to the spout main body 10, the central cylindrical body 37 is inserted into the cylindrical slide member 50 accommodated in the spout main body 10. The central cylindrical body 37 has two step portions 38 as first guide portions that protrude outward from the outer peripheral surface. The step portion 38 is formed corresponding to a guide rib 54 as a second guide portion included in the slide member 50 described later. The lower surface 38a of the stepped portion 38 is inclined upward in the opening direction. And the step part 38 is formed in the substantially right-angled triangle shape which the oblique side inclined upwards toward the opening direction by the side view. In addition, although the inclination direction with respect to the opening direction of the lower surface 38 a of the stepped portion 38 is the same as the inclination direction of the male screw 12 of the spout main body 10, the inclination angle is larger than that of the male screw 12.

  The two step portions 38 are each formed on a substantially half circumferential surface of the outer periphery of the central cylindrical body 37, and are formed point-symmetrically with respect to the axis of the central cylindrical body 37 in a bottom view. When the cap 30 is rotated in the opening direction, the step portion 38 is configured such that the guide rib 54 of the slide member 50 is in sliding contact with the lower surface 38a of the step portion 38 so that the slide member 50 contacts the spout main body 10. On the other hand, it is configured to be moved downward.

  In addition, the step part 38 as a 1st guide part is formed corresponding to the guide rib 54 as a 2nd guide part which the slide member 50 mentioned later has, and when the cap 30 is rotated in the opening direction, it is a guide rib. What is necessary is just to be comprised so that 54 may be slidably contacted to the step part 38 and the slide member 50 may be moved below with respect to the spout main body 10. FIG.

  The band 33 is formed in a cylindrical shape coaxial with the cylindrical outer wall portion 31, and the outer diameter of the band 33 is substantially the same as the outer diameter of the outer wall portion 31. At the upper end of the band 33, an annular top portion 39 that protrudes inward from the inner peripheral surface is formed. The band 33 is coupled to the lower side of the cap 30 by a thin coupling member 40 having an upper end connected to the lower end of the outer wall portion 31 and a lower end connected to the top portion 39 of the band 33.

  The band 33 has four ratchet claws 41 protruding inward from the inner peripheral surface. The four ratchet claws 41 are formed corresponding to the ratchet protrusions 23 of the spout main body 10 described above. When viewed from the bottom, the end surface of the ratchet claw 41 in the opening direction and the inner peripheral surface of the band 33 (through the joint between the end surface of the ratchet claw 41 in the opening direction and the inner peripheral surface of the band 33, The angle between the ratchet claw 41 and the inner peripheral surface of the band 33 (the end surface of the ratchet claw 41 in the closing direction and the inner peripheral surface of the band 33) is an acute angle. The angle formed with the surface of the band 33 that contacts the inner peripheral surface of the band 33 is an obtuse angle. The ratchet pawl 41 does not engage with the ratchet protrusion 23 of the spout body 10 when the band 33 rotates in the closing direction with respect to the spout body 10, and the band 33 rotates in the opening direction. When doing so, it is configured to be engaged with the ratchet projection 23 to restrict the rotation of the band 33 in the opening direction.

  When the cap 30 is attached to the spout main body 10, the band 33 is disposed between the turnip 22 of the spout main body 10 and the flange base portion 14 (see FIG. 4). When the cap 30 is rotated in the opening direction, the ratchet pawl 41 is engaged with the ratchet protrusion 23, and the rotation of the band 33 in the opening direction with respect to the spout main body 10 is restricted. Further, when the cap 30 is rotated, the thin connecting member 40 is broken and the cap 30 and the band 33 are separated. Then, the cap 30 is removed from the spout main body 10 with the band 33 remaining between the turnip 22 and the flange base 14. As described above, the cap 30 has a tamper-evident preventing function, that is, a so-called pill fur proof function, which can be seen at a glance whether or not initial opening has been performed. In addition, the structure which exhibits such a pilfer proof function is not limited to the above-described bunt 33. The cap 30 preferably has a pilfer proof function, but may not include the band 33.

  As shown in FIGS. 4, 10, and 11, the slide member 50 is formed in a cylindrical shape extending in the vertical direction, and is disposed on the inner peripheral surface side of the spout main body 10 and above the closing portion 18. The outlet body 10, the cap 30, and the central cylinder 37 are accommodated on the same axis. The slide member 50 is configured to be moved downward with respect to the spout main body 10 by the central cylinder 37 when the cap 30 is rotated in the opening direction. Here, FIG. 10 is a plan view of the slide member 50 of the spout assembly 1 of FIG. 1, and FIG. 11 is a view in the direction of the arrow XI of the slide member 50 of FIG. Further, in FIG. 10, the closing direction d1 and the opening direction d2 of the cap 30 in the state accommodated in the spout main body 10 are indicated by arrows.

  As shown in FIG. 5, the outer diameter of the slide member 50 is smaller than the diameter of the outer edge of the thin central portion 17c (the diameter of the joint portion between the thin central portion 17c and the thin peripheral edge portion 17a on the outer side). is there. The inner diameter of the slide member 50 is smaller than the diameter of the inner edge of the thin central portion 17c (the diameter of the joint between the thin central portion 17c and the inner thin edge 17b). That is, the slide member 50 is formed corresponding to the thin central portion 17 c and the outer edge portion of the closing portion 18. It should be noted that the slide member 50 is accommodated inside the spout main body 10, and the center cylindrical body 37 of the cap 30 can be inserted into the slide member 50. The diameter and the size of the inner diameter are not particularly limited.

  The slide member 50 has two piercing portions 51 facing the closing portion 18 at the lower end. The two piercing portions 51 are arranged symmetrically with respect to the axis of the slide member 50 in plan view. The piercing portion 51 has a substantially isosceles trapezoidal shape in a side view, and is formed in a tapered shape downward. Further, the piercing portion 51 has an outer surface inclined inward from the upper side to the lower side, and is formed in a tapered shape also in the radial direction. The piercing top portion 52 located at the lowest end of the piercing portion 51 is a flat surface parallel to the upper surface of the closing portion 18 in a side view.

  Further, the slide member 50 has four guide portions 53 that protrude outward from the outer peripheral surface on the upper side. The guide part 53 is formed corresponding to the main body guide part 20 of the spout main body 10. The guide parts 53 are arranged at substantially equal intervals in the circumferential direction. In plan view, the diameter connecting the outer side end, which is the tip of the guide portion 53, is slightly smaller than the diameter of the inner peripheral surface of the spout main body 10. That is, the slide member 50 can be accommodated inside the spout body 10 without the guide portion 53 being caught on the inner peripheral surface of the spout body 10.

  Here, the end surface of the guide portion 53 on the opening direction side and the outer peripheral surface of the slide member 50 (the outer periphery of the slide member 50 passes through the joint portion between the end surface of the guide portion 53 on the opening direction side and the outer peripheral surface of the slide member 50). The angle formed with the surface contacting the surface is substantially a right angle. On the other hand, the end surface of the guide portion 50 in the closing direction and the outer peripheral surface of the slide member 50 (the outer peripheral surface of the slide member 50 passes through the joint portion between the end surface of the guide portion 53 in the closing direction and the outer peripheral surface of the slide member 50). The angle formed with the surface in contact with is an obtuse angle.

  When the slide member 50 rotates in the closing direction with respect to the spout main body 10, the guide portion 53 does not engage with the main body guide portion 20 of the spout main body 10, and the slide member 50 is opened. When rotating in the direction, it is configured to be engaged with the main body guide portion 20 to restrict the rotation of the slide member 50 in the opening direction. When the slide member 50 rotates in the closing direction inside the spout main body 10, the guide portion 53 does not engage with the main body guide portion 20 of the spout main body 10, and the slide member 50 is opened. When rotating in the direction, the shape and the configuration are not particularly limited as long as the configuration is such that the rotation in the opening direction of the slide member 50 is restricted by engaging with the main body guide portion 20.

  Further, the slide member 50 has two guide ribs 54 as second guide portions protruding inward from the inner peripheral surface. Each of the two guide ribs 54 is formed on a substantially half circumferential surface of the inner periphery of the slide member 50, and is formed in point symmetry with respect to the axis of the slide member 50 in plan view. The guide rib 54 is formed corresponding to the step portion 38 of the cap 30, is inclined upward from the lower end portion toward the opening direction, and extends to the upper end portion. The guide rib 54 is formed so that the upper surface 54 a contacts the lower surface 38 a of the step portion 38 in the circumferential direction when the central cylinder 37 of the cap 30 is inserted into the slide member 50. The inclination direction of the guide rib 54 with respect to the opening direction is the same as the inclination direction of the female thread 34 of the cap 30, but the inclination angle is larger than that of the female thread 34. The step portion 38 as the first guide portion and the guide rib 54 as the second guide portion are such that the upper surface 54a of the guide rib 54 is below the step portion 38 when the cap 30 is rotated in the opening direction. The sliding member 50 is configured to be moved downward relative to the spout main body 10.

  The spout assembly 1 may be a material having excellent moldability, flexibility, excellent adhesion, and excellent adhesion to a container, preferably excellent thermal adhesion. More specifically, the material of the outlet assembly 1 is polyethylene resin, polypropylene resin, polystyrene resin, polycarbonate resin, polyester resin, polyamide resin, acrylonitrile / styrene copolymer, acrylonitrile / styrene / butadiene. A copolymer, a polyacetal resin, or the like can be used, and further, a mixture of these resins may be used. Then, by using these resins, three parts of the spout main body 10, the cap 30, and the slide member 50 are respectively formed by injection molding or the like, and the spout combination 1 can be produced by combining these parts. it can. In addition, the dimension of the spout combination 1 is not limited, It can design suitably according to the magnitude | size of the container to be attached, the fluidity | liquidity of the content of a container, etc.

  Next, the assembly method of the spout main body 10, the cap 30, and the slide member 50 in the spout combination 1 according to the present embodiment will be described in detail. First, the central cylinder 37 of the cap 30 is inserted into the slide member 50 and the cap 30 and the slide member 50 are fitted. At this time, the upper surface 54 a of the guide rib 54 of the slide member 50 is in sliding contact with the lower surface 38 a of the step portion 38 of the central cylindrical body 37, and the slide member 50 rotates in the opening direction with respect to the cap 30. 30.

  Next, the fitted cap 30 and slide member 50 are integrally attached to the spout main body 10. Specifically, the cap 30 is covered with the spout body 10 so that the slide member 50 and the central cylinder 37 of the cap 30 are inserted into the opening 11 of the spout body 10. Next, when the cap 30 is rotated in the closing direction with respect to the spout main body 10, the male screw 12 of the spout main body 10 and the female thread 34 of the cap 30 engage with each other, and the cap 30 is screwed into the spout main body 10. Go. Since the band 33 is connected to the cap 30 by the connecting member 40, the cap 30 and the band 33 rotate integrally. Moreover, since the center cylinder 37 is inserted in the slide member 50 and the cap 30 is fitted, the cap 30 and the slide member 50 rotate integrally.

  Here, the cap 30 is screwed into the spout main body 10 while the guide portion 53 formed on the outer peripheral surface of the slide member 50 gets over the main body guide portion 20 formed on the inner peripheral surface of the spout main body 10. . The angle formed by the end surface of the guide portion 53 in the closing direction and the outer peripheral surface of the slide member 50 is an obtuse angle, and the end surface in the opening direction of the main body guide portion 20 and the inner peripheral surface of the spout main body 10 are obtuse. The angle formed is an obtuse angle. Therefore, since the main body guide portion 23 and the guide portion 53 abut against each other so that the end surfaces on the obtuse angle side rub against each other, the guide portion 53 can easily get over the main body guide 20.

  Further, although the ratchet claw 41 included in the band 33 gets over the ratchet protrusion 23 included in the spout main body 10, the ratchet claw 41 and the ratchet protrusion 23 are obtuse to each other in the same manner as the relationship between the main body guide portion 23 and the guide portion 53. The end faces on the side are in contact with each other so as to rub against each other. Therefore, the ratchet pawl 41 can easily get over the ratchet protrusion 23.

  When the cap 30 is further rotated, the inner ring 36 formed on the top surface 32 is inserted into the opening 11 of the spout main body 10 and is fitted into the spout main body 10. The rotation is completed, and the spout assembly 1 is produced. At this time, since the outer peripheral surface of the inner ring 36 is in close contact with the inner peripheral surface of the spout main body 10, the opening 11 of the spout main body 10 is sealed by the top surface 32 of the cap 30 and the inner ring 36. Further, in the spout assembly 1 in which the spout main body 10, the cap 30 and the slide member 50 are combined, the pierced top portion 52 of the slide member 50 is positioned so as to contact the upper surface of the closing portion 18.

  Here, the assembly operation of the spout assembly 1 includes the step of inserting the central cylindrical body 37 of the cap 30 into the slide member 50 and fitting the cap 30 and the slide member 50 together, and the slide member 50 being fitted. Only the step of attaching the combined cap 30 to the spout main body 10 by screwing is performed. Accordingly, the production of the spout outlet assembly 1 does not require an adhesive operation or the like, and it is only necessary to assemble the spout main body 10, the cap 30, and the slide member 50. Further, the assembly operation has a small number of processes and each process is simple, so that the productivity of the spout assembly 1 is good.

  In addition, the assembly method of the spout main body 10, the cap 30, and the slide member 50 in the spout union assembly 1 is not limited to the above-mentioned method. For example, first, the slide member 50 is accommodated in the spout main body 10 from the opening 11. Next, the cap 30 is covered on the opening 11 side of the spout body 10 so that the central cylinder 37 of the cap 30 is inserted into the slide member 50 housed inside the spout body 10. Next, the cap 30 is rotated in the closing direction with respect to the spout main body 10, and the central cylinder 37 is inserted into the slide member 50, while the male screw 12 of the spout main body 10 and the female thread 34 of the cap 30 are inserted. And the cap 30 is screwed into the spout main body 10. Then, until the rotation of the cap 30 with respect to the spout main body 10 is completed, the cap 30 is rotated in the closing direction while the central cylinder 37 is inserted into the slide member 50. Even if it is such a method, the spout combination 1 can be produced, the effect similar to the above-mentioned method is acquired, and the productivity of the spout combination 1 is favorable.

  In addition, the inclination direction with respect to the opening direction of the lower surface 38a of the stepped portion 38 as the first guide part and the inclination direction with respect to the opening direction of the guide rib 54 as the second guide part are the male screw 12 of the spout main body 10. And the inclination direction of the internal thread 34 of the cap 30 is the same. That is, when the cap 30 is rotated in the closing direction and screwed into the spout main body 10, the upper surface 54 a of the guide rib 54 comes into sliding contact with the lower surface 38 a of the stepped portion 38, and the slide member 50 moves relative to the cap 30. The central cylinder 37 is inserted and fitted into the cap 30 while rotating in the opening direction.

  The container with a spout assembly according to this embodiment includes a spout assembly 1. FIG. 12 is a cross-sectional view of a main part illustrating an example of a container 70 with a spout assembly that includes the spout assembly 1 according to the present embodiment. FIG. 12 illustrates a container 70 with a spout assembly in which the spout assembly 1 is attached to a paper container 60. In addition, FIG. 12 is a vertical sectional view similar to FIG. 4, in which the upper part of the spout assembly 1 and the paper container 60 is shown in section.

  The paper container 60 is formed from a laminated material having a multilayer structure in which paper is a base material layer. The laminated material constituting the paper container 60 is appropriately selected according to the properties of the contents and the functions required of the laminated material as a paper container. As a laminated material, for example, a three-layer structure in which a paper base material layer, a barrier layer, and an inner layer are laminated in order from the outside can be used.

The paper base layer is a main strength material, and various paper materials such as milk base paper, pure white roll paper, coated paper, craft paper, paperboard, and processed paper can be used. The basis weight of the paper material used for paper substrate layer can be appropriately determined depending on the form of a paper container, the basis weight is preferably ^{80g / m 2 ~600g / m 2} , 100g / m 2 ~ and more preferably 450 g / m ^2. The thickness is preferably 110 μm to 860 μm, and more preferably 140 μm to 640 μm.

  The barrier layer is for light shielding and prevention of permeation of gases such as oxygen, aluminum foil, biaxially stretched nylon film with a deposited layer of silica, aluminum, etc., and a deposited layer of silica, aluminum, etc. The polyethylene terephthalate film etc. which were made can be used.

  The inner layer holds the liquid contents and plays a role of adhesion at the time of forming the paper container, and a thermoplastic resin having heat sealability can be used. For example, polyolefin resins such as polyethylene and polypropylene can be used. From the viewpoint of processability, it is preferable to use low density polyethylene or linear low density polyethylene. In addition, the thickness of an inner layer is not specifically limited, It is 10 micrometers-120 micrometers, More preferably, it is 20 micrometers-60 micrometers.

  The laminated material constituting the paper container 60 is not limited to the above-described configuration. For example, a printing layer or a protective layer made of a thermoplastic resin similar to the above-described inner layer is provided outside the paper base layer. The structure provided may be sufficient. Moreover, the lamination method of each layer is not limited.

  The paper container 60 has a roof shape in which an upper portion 61 is inclined, and a barrel portion 62 is a gable top type having a rectangular tube shape. However, the form of the paper container 60 is not particularly limited as long as it has a flat panel to which the spout assembly 1 can be attached. For example, a flat top type having a flat upper portion. Etc.

  In the state before joining where the mating portion 63 of the upper part 61 of the paper container 60 is opened, the spout assembly 1 is placed on the inner side of the paper container 60 in the hole formed in the inclined panel 64 (laminate material) of the upper part 61. Insert from. At that time, the spout assembly 1 is inserted into the hole from the cap 30 side so that the inner surface of the panel 64 and the upper surface of the flange 13 face each other. Then, the spout assembly 1 is pushed in from the inward side so that the outer edge of the hole of the panel 64 gets over the claw portion 15 formed in the flange base portion 14, and the panel 64 is arranged between the claw portion 15 and the flange 13. . In addition, the shape of the hole previously formed in the panel 64 respond | corresponds to the external shape of the flange base 14, and the flange base 14 is fitted by the hole. Then, the spout assembly 1 is attached to the paper container 60 by fixing the upper surface of the flange 13 and the inner surface of the panel 64 by ultrasonic welding, heat welding, adhesive, or the like.

  Since the flange base portion 14 is fitted into the hole of the panel 64 and the spout assembly 1 is temporarily fixed to the paper container 60, the spout assembly 1 can be easily fixed to the paper container 60. Furthermore, since the claw portion 15 is formed on the flange base portion 14, the spout assembly 1 in which the flange base portion 14 is fitted in the hole of the panel 64 is locked to the panel 64 by the claw portion 15. That is, since the spout combination 1 is temporarily fixed to the paper container 60 more firmly, the fixing operation of the spout combination 1 to the paper container 60 can be performed more easily.

  The attaching operation of the spout assembly 1 to the paper container 60 includes the step of pushing the spout member 1 into the hole of the panel 64 until the upper surface of the flange 13 comes into contact with the inner surface of the container 60, and the upper surface of the flange 13 and the panel. It is only the process of adhering to the inner surface of 64. Therefore, the container 1 with the spout assembly is not required to adhere a member other than the spout assembly 1, and can be produced simply by attaching the spout assembly 1 to the paper container 60. Furthermore, since the number of steps is small and each step is simple, the productivity of the container 70 with a spout assembly is good.

  Here, the spout assembly 1 is attached to the paper container 60 in a state before the paper container 60 is boxed, that is, in a blank state formed by punching the laminated material forming the paper container 60. May be. When attaching in such a state, since the spout assembly can be attached to a flat blank, the operation is further facilitated.

  Moreover, the filling method of the content to the container 70 with a spout union body is not specifically limited. For example, the spout assembly 1 is attached to the paper container 60 as described above in a state before joining in which the mating portion 63 of the upper portion 61 of the paper container 60 is opened. Then, the contents are filled from the opening opened by the mating portion 63, and the mating portion 63 is joined to seal the paper container 60. In this way, the contents can be filled into the container 70 with the spout assembly.

  Furthermore, the container 70 with the spout combination is not limited to the paper container described above. For example, it may be a pouch that is formed in a bag shape by laminating its peripheral portion after a flexible film is overlaid. When the spout assembly 1 is attached to the pouch, for example, in the state where the non-adhered peripheral portion is left on the pouch, as in the case of the paper container 60, the pour-out assembly 1 is poured into a hole formed in advance on one film. The outlet assembly 1 may be inserted from the inner side of the pouch and the inner surface of the pouch (film) and the upper surface of the flange 13 may be fixed.

  Moreover, it replaces with the flange 13, and it is set as the structure provided with the boat-shaped attachment part which protrudes from the spout main body 10 to the both sides of a diametrical direction in a substantially triangular shape, and is substantially rectangular in front view instead of the flange 13. The pouch may be attached to the boat-shaped attachment portion. Specifically, the spout assembly 1 and the film constituting the pouch are arranged so that the side of the cap 30 is located outside the pouch and the boat-shaped attachment is located at the peripheral edge of the pouch. And the inner surface of one film which comprises a pouch is adhere | attached on the one side surface of an attachment part, and the inner surface of the other film which comprises a pouch is adhere | attached and attached to the other side surface of an attachment part. Note that the boat-shaped attachment portion is bonded to the pouch by ultrasonic welding, heat welding, adhesive, or the like.

  The film constituting the pouch is selected according to the nature of the contents and the function required for the film as a packaging material. The film may be a single layer or a multilayer. In the case of a multilayer film, for example, a two-layer structure in which a heat seal layer and a base material layer are laminated from the inside can be used, and the inner heat seal layer and the attachment portion can be easily heat-welded.

  For the heat seal layer, a film made of a thermoplastic resin having heat sealability can be used. For example, a film made of a polyolefin resin such as polyethylene or polypropylene can be used. The thickness of the heat seal layer is preferably 10 μm or more, more preferably 40 μm or more, and particularly preferably 80 μm to 200 μm.

  For the base material layer, for example, a biaxially stretched film made of polypropylene, polyethylene terephthalate, polyamide or the like can be used. The thickness of the base material layer is preferably 10 μm to 50 μm, and more preferably 12 μm to 25 μm. Furthermore, the heat seal layer is preferably 2 to 20 times as thick as the base material layer, and more preferably 4 to 10 times thick.

  In the case of a multilayer film, a barrier layer or a printing layer may be further provided in the same manner as the laminated material constituting the paper container 60. Moreover, the lamination method of each layer is not limited.

  Furthermore, there is no particular limitation on the packaging form of the pouch, and various types such as standing pouches, two-side sealed bags, three-side sealed bags, four-side sealed bags, gusset bags, pillow packaging bags, square bottom bags, back-in-box inner bags, etc. It can be used by selecting from the packaging form.

  Furthermore, the container 70 with a spout combination is not limited to the paper container and the packaging container described above, but may be a bottle. The bottle may be a plastic bottle made of a flexible material, for example, or may be a glass bottle made of a non-flexible material. And the attachment part of the spout union assembly 1 is suitably designed and attached according to the form of the mouth part of a bottle.

  Next, the initial opening method of the container 70 with a spout combination which concerns on this embodiment is demonstrated in detail. FIG. 13 is a plan view showing a state in which the guide 53 is engaged with the main body guide portion 20, and FIGS. 14 and 15 are cross-sectional views of main parts showing a state when the movement of the slide member 50 is completed. is there. In FIG. 13, the description of the cap 30 is omitted, and the closing direction d1 and the opening direction d2 of the cap 30 are indicated by arrows. 14 is a vertical cross-sectional view in which the spout assembly 1 and the panel 64 of the paper container 60 are shown in cross-section, and the same cross-section as in FIG. 12 described above is shown, and the lower side of FIG. Inside. FIG. 15 is a vertical cross-sectional view showing a cross section of the spout assembly 1 and the panel 64 of the paper container 60, which is a cross section different from FIG. 14 and showing a cross section taken along the line XV-XV of FIG. That is, FIG. 15 is a sectional view showing a section perpendicular to the paper surface in FIG. Further, the lower side of FIG. 15 is the inside of the paper container 60.

  In the initial sealed state of the spout assembly 1, as shown in FIG. 12, the closing portion 18 is connected to the inner peripheral surface of the spout body 10 through the thin portion 17, and the spout portion 18 The side below the slide member 50 of the main body 10 is sealed. From such an initial state, the cap 30 is rotated in the opening direction with respect to the spout main body 10, whereby the initial opening is performed. When the cap 30 is rotated in the opening direction with respect to the spout main body 10, the slide member 50 fitted to the cap 30 and the band 33 connected to the cap 30 rotate together with the cap 30.

  And as FIG. 13 shows, the guide part 53 formed in the outer peripheral surface of the slide member 50 does not get over the main body guide part 20 formed in the inner peripheral surface of the spout main body 10 toward an opening direction. The main body guide portion 20 is engaged. Here, the angle formed by the end surface on the opening direction side of the guide portion 53 and the outer peripheral surface of the slide member 50 is substantially a right angle, and the end surface on the plugging direction side of the main body guide portion 20 and the inner peripheral surface of the spout main body 10. The angle formed by is substantially a right angle. Accordingly, the guide portion 53 and the main body guide portion 20 are in contact with each other so that the substantially right end faces are hooked, and the guide portion 53 engages with the main body guide portion 20. And the rotation to the opening direction of the slide member 50 with respect to the spout main body 10 is controlled because the guide part 53 engages with the main body guide part 20.

  In the state where the guide portion 53 is engaged with the main body guide portion 20, the piercing portion 51 of the slide member 50 is located at a position corresponding to any of the protrusions 19 formed on the thin portion 17 in plan view. A guide portion 53, a main body guide portion 20, a piercing portion 51, and a protrusion 19 are arranged.

  When the cap 30 is further rotated in the opening direction with the guide portion 53 engaged with the main body guide portion 20, the upper surface 54 a of the guide rib 54 of the slide member 50 is below the step portion 38 of the central cylindrical body 37. The sliding member 50 is slidably contacted with the side surface 38a, and is moved downward relative to the cap 30 without rotating in the opening direction with respect to the spout main body 10. The slide member 50 rotates with respect to the cap 30 in the closing direction.

  When the slide member 50 moves downward, the piercing portion 51 connects the closing portion 18 that has sealed the lower side of the spout main body 10 with respect to the slide member 50, and connects the spout main body 10 and the closing portion 18. The thin portion 17 to be pressed is pushed down. At this time, the piercing top portion 52 at the tip of the piercing portion 51 comes into contact with the closing portion 18 and the thin portion 17. And the site | part located in the vicinity of the piercing part 51 in the thin center part 17c of the thin part 17 is fractured | ruptured. At this time, since the force of engagement between the male screw 12 of the spout body 10 and the female screw 34 of the cap 30 is used, the thin central portion 17c is broken by the piercing portion 51 without requiring a strong force. It can be carried out. Further, the piercing portion 51 has a tapered shape toward the lower side, and since the force is concentrated on the piercing top portion 52 at the tip, the thin central portion 17c can be more easily broken.

  Here, the thin center part 17c has the protrusion 19 corresponding to the piercing part 51, and the rigidity of the formed part is improved. Accordingly, the force acting on the thin central portion 17c tends to concentrate on the protrusion 19 with improved rigidity. Further, as shown in FIG. 3, the protrusion 19 has a tapered shape from the end on the closed portion 18 side toward the outside in the radial direction, and within the edge of the protrusion 19, a force is applied to the tapered tip. Easy to concentrate. That is, the force acting on the thin central portion 17c is effectively concentrated on the tip of the projection 19, and the thin central portion 17c is broken at the edge of the tip of the projection 19. Therefore, the thin central portion 17c can be broken more easily.

  The piercing portion 52 is not for cutting the thin portion 17 but for pushing down the closing portion 18 and the thin portion 17. And the piercing top part 52 is a flat surface parallel to the upper surface of the obstruction | occlusion part 18 by a side view, can push down the obstruction | occlusion part 18 and the thin part 17 effectively, and performs the fracture | rupture of the thin center part 17c reliably. be able to.

  Further, when the cap 30 is rotated in the opening direction, the breakage of the thin central portion 17c is propagated in the circumferential direction starting from the portion broken by the piercing portion 51 as the slide member 50 moves downward. Go. The thin edge 17a on the outer side of the thin part 17 remains on the spout body 10 side, and the thin edge 17b on the inner side remains on the closing part 18 side.

  Then, as propagation of the breakage of the thin central portion 17c proceeds, the piercing top portion 52 of the piercing portion 51 does not come into contact with the upper surface of the closing portion 18 vertically. Accordingly, the force acting on the thin wall central portion 17c by the downward movement of the piercing portion 51, and the force acting to shear the thin wall central portion 17c is weakened, and the propagation of the breakage of the thin wall central portion 17c is the thin wall central portion. It does not spread all around 17c. Then, as shown in FIG. 15, a thin connecting portion 17d, which is a portion that remains bent without breaking, is formed in the thin central portion 17c, and the spout main body 10 is blocked by the thin connecting portion 17d. It will be in the state where the part 18 was connected. Therefore, since the closed portion 18 is connected by the thin connecting portion 17d even when the thin central portion 17c is broken, it does not fall into the container 70 with the spout assembly.

  Since the slide member 50 has two piercing portions 51, the thin central portion 17c is broken in the vicinity of one of the piercing portions 51 or in the vicinity of both of the two piercing portions 51. When the vicinity of any one of the piercing portions 51 is broken, it is propagated in the circumferential direction starting from the broken portion. When the vicinity of both of the two piercing portions 51 is ruptured, it is propagated in the circumferential direction starting from these two broken portions.

  Further, the cap 30 moves upward with respect to the spout main body 10 by rotating in the opening direction. Since the inclination is greater than the inclination of the screw 34, the distance that the slide member 50 moves downward relative to the cap 30 is greater than the distance that the cap 30 moves upward relative to the spout main body 10. Therefore, the slide member 50 moves downward with respect to the spout main body 10.

  The downward movement of the slide member 50 is completed when the upper surface 54a of the guide rib 54 and the lower surface 38a of the step portion 38 are not in sliding contact. When the movement of the slide member 50 is completed, the guide portion 53 gets over the main body engaging portion 21 and engages with the main body engaging portion 21 in the vertical direction. The slide member 50 is restricted from moving upward with respect to the spout main body 10 by engaging the guide portion 53 and the main body engaging portion 21. Further, the thin central portion 17 c is broken at the lower end portion of the spout main body 10, and the thin edge portion 17 a on the outer side of the thin portion 17 remains. In the slide member 50, the guide portion 53 comes into contact with the thin edge portion 17a, and the further downward movement of the slide member 50 is restricted. Therefore, when the downward movement is completed, the slide member 50 is locked to the spout main body 10 because the guide portion 53 is positioned between the main body engaging portion 21 and the thin edge portion 17a, and the vertical direction Is configured to be restricted from moving. The locking of the slide member 50 to the spout main body 10 is not limited to the above-described configuration. For example, the slide member 50 may be further provided with a projection different from the guide portion 53, and locking using this projection may be used.

  Here, even when the movement of the slide member 50 is completed and the upper surface 54a of the guide rib 54 and the lower surface 38a of the stepped portion 38 are not in sliding contact with each other, the inner ring 36 remains in the spout main body 10. The opening 11 is sealed by the inner ring 36 and the top surface 32. Therefore, for example, even when the body portion 62 of the paper container 60 is gripped and the opening is initially performed in a state where the inside of the container 70 with the spout combination is at a positive pressure, immediately after the thin portion 17 is broken. The contents are not poured out from the opening 11 and are easy to use.

  Further, by rotating the cap 30 in the opening direction, the engagement between the male thread 12 of the spout main body 10 and the female thread 34 of the cap 30 can be removed, and the cap 30 can be removed from the spout main body 10. The ten openings 11 are opened and the initial opening is completed. The cap 30 is in a state in which the slide member 50 is detached, and the resistance force generated when the cap 30 is rotated is not small. Therefore, the consumer can recognize without observing that the thin portion 17 has been broken. And the flow path which continues from the inside of the container 70 with a spout union to the inside of the slide member 50, the inside of the spout main body 10, and the opening 11 is formed, and the contents can be poured out from the opening 11.

  In addition, the band 33 connected to the cap 30 is broken at the time of initial opening as described above, and the band 33 remains between the turnip 22 and the flange base 14 to prevent unauthorized opening. Can do. On the other hand, the container with spout assembly 70 can be resealed and is convenient. Specifically, it can be resealed by attaching the cap 30 to the spout main body 10 by engaging the external thread 12 and the internal thread 34. When resealed, the inner ring 36 is fitted into the opening 11 and the opening 11 is sealed.

  Here, the slide member 50 is locked to the spout main body 10 by the main body engaging portion 21 and the thin edge portion 17a on the outer side of the thin portion 17 remaining on the spout main body 10 side. In addition, the contents can be well poured out without falling into the container 70 with the spout outlet assembly and without jumping out from the opening 11 of the spout main body 10. Further, the slide member 50 does not hinder resealing. Further, since the slide member 50 protrudes inward from the lower end of the spout main body 10 to the container 70 with the spout assembly, the closing portion 18 does not return so as to block the content flow path, and the content is poured. Can perform well.

  In addition, since the closed portion 18 is connected by the thin-walled connecting portion 17d even when the thin-walled central portion 17c is broken, the closed portion 18 is not dropped into the container 70 with the spout assembly. The contents can be dispensed well without being mixed or blocking the contents flow path. Even when the entire circumference of the thin central portion 17c is broken and the closing portion 18 falls out of the container 70 with the spout assembly, the disc-like closing portion 18 is different from a film or the like. Since there is little flexibility and it is hard to deform | transform, it does not pass through the inside of the slide member 50, and it is not discharged | emitted from the opening 11 with the content.

  In addition, the slide member 50 is inclined with respect to the axis of the spout main body 10 and the cap 30 in order to push down the closing portion 18 and the thin portion 17 with the two piercing portions 51 arranged symmetrically with respect to the axis of the slide member 50. When the thin central portion 17c is broken, the slide member 50 is not sandwiched between the spout main body 10 and the cap 30, and the thin central portion 17c can be favorably broken.

  Moreover, since the container 70 with a spout union is initially opened by breaking the thin central portion 17c, it can maintain high sealing performance until the initial opening, and the contents are stored for a long time. It can use suitably for etc.

  In addition, the spout main body 10, the cap 30, and the slide member 50 which comprise the spout union assembly 1 are not limited to the above-mentioned structure. For example, the two piercing top portions 52 and 52 of the slide member 50 may be configured such that their positions are different in the vertical direction. By adopting such a configuration, when the slide member 50 moves downward, the thin central portion 17c is first broken at a portion corresponding to the piercing portion 51 where the piercing top portion 52 is located below, The part corresponding to the other piercing top 51 is broken. That is, the force acting on the thin-walled central portion 17c is not dispersed in two locations but acts in a concentrated manner in each location, so that the thin-walled central portion 17c can be more easily broken. Note that the number of piercing portions 51 is not limited to two, and may be one or three or more.

  Moreover, although description by illustration is abbreviate | omitted, the structure which has the notch part notched from the lower end to the upper part between the two piercing parts 51 may be sufficient as the slide member 50 in the circumferential direction. The upper end of the notch is positioned above the lower end of the guide 53. That is, the slide member 50 may be configured to include two piercing portions 51 extending in a leg shape from the upper part. With such a configuration, when the downward movement of the slide member 50 is completed, the upper end of the notch portion is positioned on the upper side of the closing portion 18. That is, the cutout portion of the slide member 50 does not exceed the thin portion 17, and the propagation of breakage of the thin central portion 17 c stops at a position corresponding to the cutout portion, and spreads over the entire circumference of the thin central portion 17 c. Is reliably prevented. And the thin connection part 17d is formed in the site | part corresponding to this notch part. Therefore, it can prevent reliably that the obstruction | occlusion part 18 falls out into the inside of the container 70 with an outlet assembly. Moreover, since the notch becomes a flow path for the contents, the contents can be poured out at a higher speed.

  Further, when the cap 30 is rotated in the opening direction, the configuration in which the slide member 50 is moved downward with respect to the spout main body 10 is a step as a first guide portion formed on the outer peripheral surface of the central cylindrical body 37. It is not limited to the structure by the part 38 and the guide rib 54 as a 2nd guide part formed in the internal peripheral surface of the slide member 50. FIG. For example, the second guide portion may be a step portion protruding inward from the inner peripheral surface, similarly to the step portion 38 as the first guide portion. In such a configuration, the upper surface of the stepped portion as the second guide portion is in sliding contact with the lower surface 38a of the stepped portion 38 as the first guide portion, and the slide member 50 is connected to the cap 30 and the note. The outlet body 10 is moved downward.

  Further, the first guide portion may be a rib that protrudes outward from the outer peripheral surface, similarly to the guide rib 54 as the second guide portion. The first guide portion may be a male screw similar to the male screw 12 of the spout main body 10, and the second guide portion may be a female screw similar to the female screw 34 of the cap 30. In such a configuration, the pitch of the male screw as the first guide portion and the female screw as the second guide portion is larger than the pitch of the male screw 12 and the female screw 34. Even with such a configuration, the slide member 50 can be moved downward relative to the spout main body 10 when the cap 30 is rotated in the opening direction.

  Here, in the initial opening in the container 70 with the spout outlet assembly, the thin member 17 is broken by moving the slide member 50 downward with respect to the spout main body 10 and the piercing part 51 pushes down the closing part 18. Made. When the strength of the thin-walled portion 17 is high, the initial opening property tends to be lowered, and when the strength of the thin-walled portion 17 is low, the productivity of the spout assembly 1 and the container 70 with the spout-combined assembly tends to be lowered. Further, when the strength of the slide member 50 is low with respect to the spout main body 10, the initial opening property is likely to be lowered. Therefore, it is necessary for the spout union assembly 1 to have a configuration in consideration of the initial opening property and productivity.

  And from a viewpoint of initial opening property etc., it is preferable that the slide member 50 is made of a material that is stronger than the spout main body 10 and the spout main body 10 is made of a material having excellent flexibility. For example, the material of the spout body 10 is preferably low density polyethylene or linear low density polyethylene, and the material of the cap 30 and the slide member 50 is preferably polypropyne, polystyrene, acrylonitrile / styrene / butadiene copolymer, polycarbonate, or the like. . By comprising from such a material, the thin center part 17c can be suitably fractured at the time of initial opening. Further, it is possible to more reliably prevent the propagation of the breakage of the thin central portion 17c from spreading to the entire circumference and the formed thin connecting portion 17d from being broken.

  In addition, from the viewpoint of initial opening property, productivity, etc., the radial width w1 of the thin central portion 17c of the thin portion 17 is preferably 0.1 mm or more and 1.0 mm or less, and the upper and lower portions of the thin central portion 17c are The thickness t1 in the direction is preferably 0.1 mm or more and 0.3 mm or less, and the radial width w2 of the thin central portion 17c at the portion where the projection 19 is formed is 0.1 mm or more and 0.3 mm. The following is preferable (see FIG. 5). If the width w1 in the radial direction of the thin central portion 17c is less than 0.1 mm, it is difficult to break the thin central portion 17c at the time of initial opening, and the initial opening property is lowered, which is not preferable. On the other hand, when the width w1 in the radial direction of the thin central portion 17c is larger than 1.0 mm, it is difficult to mold, and productivity is not preferable. Moreover, it becomes difficult to shape | mold that the thickness t1 of the up-down direction of the thin center part 17c is less than 0.1 mm. Further, the strength of the thin central portion 17c is weak, and the thin central portion 17c is easily broken when the spout assembly 1 is assembled or when the container 70 with a spout assembly is manufactured. On the other hand, when the thickness t1 in the vertical direction of the thin central portion 17c is larger than 0.3 mm, it is difficult to break the thin central portion 17c at the time of initial opening, and the initial opening property is lowered, which is not preferable. When the radial width of the thin central portion 17c at the portion where the protrusion 19 is formed is 0.1 mm or more and 0.3 mm or less, the thin central portion 17c can be suitably broken at the time of initial opening.

  Further, from the viewpoint of initial opening property, the slide member 50 is moved downward with respect to the cap 30 with respect to the distance that the cap 30 moves upward with respect to the spout main body 10 when the cap 30 is rotated in the opening direction. The ratio of the moving distance is preferably 2.0 or more and 7.0 or less. If this ratio is less than 2.0, the number of rotations of the cap 30 at the time of initial opening increases, and the initial opening property is lowered, which is not preferable. Moreover, the spout union assembly 1 becomes larger in the vertical direction and cannot be made compact. On the other hand, if this ratio is greater than 7.0, the force required to rotate the cap 30 increases, and the initial opening property is lowered, which is not preferable.

  As described above, the spout assembly 1 according to the present embodiment has a cylindrical spout body 10 that extends vertically and has a screw 12 and a flange 13 joined to the container formed on the outer peripheral surface. A cylindrical outer peripheral wall 31 formed on the inner peripheral surface of a female screw 34 that meshes with the male screw 12, and a top surface 32 that closes the upper end of the outer peripheral wall 31, and is attached to the spout main body 10. A spouted cylindrical cap 30 that closes the upper end of the spout main body 10 and a cylindrical slide member 50 that moves in the vertical direction on the inner peripheral surface side of the spout main body 10. Is connected to the inner peripheral surface via the thin-walled portion 17 that can be broken, and seals the lower side of the slide member 50 on the inner peripheral surface on the upper side of the closed portion 18. And a main body guide portion 20 that protrudes upward and downward in the vertical direction. A step portion 38 extending downward from the outer peripheral surface 32 and projecting outward is formed on the outer peripheral surface, and has a cylindrical central cylinder 37 inserted into the slide member 50. The slide member 50 has a closed portion at the lower end. A piercing portion 51 that faces 18, a guide portion 53 that protrudes outward from the outer peripheral surface, engages with the main body guide portion 20, and is restricted from rotating in the opening direction with respect to the spout main body 10; When the cap 30 is rotated in the opening direction, the slide member 50 moves downward relative to the spout main body 10 with the guide portion 53 slidably contacting the step portion 38. Then, when the piercing portion 51 pushes down the closing portion 18, the thin portion 17 is configured to be broken.

  According to the configuration according to the present embodiment, the spout assembly 1 can be produced only by assembling the spout body 10, the cap 30, and the slide member 50 without bonding or the like. Productivity is good. Moreover, without attaching members other than the spout union assembly 1, the container 70 with a spout union assembly can be produced simply by attaching the spout union assembly 1 to the container. It is good.

  Therefore, according to the present embodiment, it is possible to provide the spout assembly 1 and the spout assembly-attached container 70 having high initial sealing performance and excellent production.

  The present disclosure can be suitably used for the spout combination 1 attached to the container and the container 70 with the spout combination including the same. However, the present disclosure is not limited to the above-described embodiments. The contents filled in the container with the spout assembly of the present disclosure are not particularly limited as long as it has fluidity, and may be food such as beverages and seasonings, daily necessaries such as cosmetics, detergents, and pharmaceuticals, and others. May be. Furthermore, since the container 70 with a spout union assembly according to the present disclosure can maintain a high hermeticity until it is initially opened, it is also suitable as a container for storing the contents for a long period of time.
