Further, the outer surface of the mouth part 12 is formed with a longitudinal groove 12b whose upper part is released, and the longitudinal rib 21b formed on the inner surface of the lower peripheral wall part 21 of the connecting member 20 connects the connecting member 20 to the mouth part 12. When the undercut fitting is performed, the vertical groove 12b is fitted. Therefore, the connecting member 20 is restricted from rotating in the circumferential direction of the mouth portion 12 in a state of being fitted to the mouth portion 12 by an undercut. In this way, the connecting member 20 is attached to the mouth portion 12.

  The connecting member 20 includes a lower peripheral wall portion 21 that is fitted to the mouth portion 12 by an undercut, an annular flange portion 22 that extends radially inward from the upper end of the lower peripheral wall portion 21, and the flange portion 22. The upper peripheral wall portion 23 erected from the radially inner edge, and the flange portion 22 hangs down from the radially inner edge along the inner surface of the mouth portion 12 into the mouth portion 12, and is flush with the inner surface of the mouth portion 12. From the inner peripheral edge of the annular bottom plate portion 25, the annular bottom plate portion 25 provided at the lower end of the sealing cylinder portion 24 And a projecting portion 26 projecting upward.

  As described above, the lower peripheral wall portion 21 is attached to the mouth portion 12 of the container body 10 by undercut fitting. The annular flange portion 22 is in contact with the upper end surface of the mouth portion 12 in a state where the lower peripheral wall portion 21 is attached to the mouth portion 12 by undercut fitting. The upper peripheral wall portion 23 has a male screw portion 23a formed on the outer surface thereof, and the cap member 30 to be described later screws the female screw portion 32c1 formed on the inner surface of the mounting cylinder portion 32c of the cap member 30 with the male screw portion 23a. Thus, the connecting member 20 is detachably mounted.

  The upper outer surface of the seal tube portion 24 is in contact with the upper inner surface of the mouth portion 12 in a state where the lower peripheral wall portion 21 is attached to the mouth portion 12 by undercut fitting, and the seal tube portion 24 and the mouth portion 12 are in contact with each other. Seal the gap. In other words, the mouth portion 12 is in a state of being fitted into an annular groove formed by the lower peripheral wall portion 21, the flange portion 22, and the seal cylinder portion 24.

  The protruding portion 26 has a cylindrical bellows portion 26a whose one end side is continuous with the inner peripheral edge of the bottom plate portion 25, a disk-shaped partition wall portion 26b which is continuous so as to cover the other end side of the bellows portion 26a, And a bowl-shaped front end portion 26c protruding upward from the upper surface of the partition wall portion 26b. An opening 26b1 is formed in the partition wall portion 26b, and the projecting extraction portion 26 divides an extraction path 27 that leads from the bellows portion 26a to the tip end of the tip end portion 26c through the opening 26b1 of the partition wall portion 26b. Yes.

  The cylindrical bellows portion 26a is axially moved by the action of the top wall portion 31 of the cap member 30 that moves by expanding and contracting a bellows portion 33 of the cap member 30 to be described later (in FIGS. 1 and 2, the central axis of the container body 2 is The same direction as the axial direction of O). A recovery hole 26a1 is formed on the peripheral wall of the cylindrical bellows portion 26a. The recovery hole 26a1 is used for returning the content Y once poured out from the protruding pour-out portion 26 into the accommodating space S. Hereinafter, for convenience of explanation, the bellows portion 33 of the cap member 30 will be referred to as a “first bellows portion 33”, and the bellows portion 26a of the protruding extraction portion 26 will be referred to as a “second bellows portion 26a”.

  The bowl-shaped tip portion 26c and the partition wall portion 26b follow the expansion / contraction deformation of the second bellows portion 26a and move in the axial direction of the second bellows portion 26a. The tip portion 26c and the partition wall portion 26b itself extend and contract. It is formed so as not to be deformed.

  Further, a fitting tube portion 28 that protrudes upward is formed in the protruding portion 26 at a position adjacent to the extraction passage 27. Specifically, the protruding portion 26 of the present embodiment includes the partition wall portion 26b described above, and the fitting cylinder portion 28 is formed by projecting the central portion of the partition wall portion 26b upward. More specifically, the above-described opening 26b1 is formed in the partition wall portion 26b of the present embodiment, and the fitting cylinder portion 28 of the present embodiment forms a part of the partition wall portion 26b at a position adjacent to the opening 26b1. It is comprised by the top cylinder part protruded upwards. In addition, the opening 26b1 of the present embodiment is formed in the distal end portion 26c in the top view of the container body 2 (see FIG. 3A), and in the circumferential direction at a position around the fitting cylinder portion 28. Three are formed at a predetermined interval (in this embodiment, a central angle of 120 degrees). In addition, a convex portion 28a is formed on the outer surface of the fitting tube portion 28 to be fitted with a tip portion of a tube portion 31b of the cap member 30 to be described later by undercut. The convex portion 28a of the present embodiment is formed by three convex ribs provided at a position corresponding to the opening 26b1 in the top view shown in FIG. 3A, but FIG. 1, FIG. 2, FIG. In b) and FIG. 4, the position of the convex portion 28 a is drawn at a different position in the circumferential direction of the fitting cylinder portion 28 in order to facilitate understanding of the fitting relationship with the concave portion 34 described later.

  Note that three openings 26b1 of the present embodiment are formed at positions around the fitting cylinder portion 28 at intervals of a central angle of 120 degrees in the circumferential direction, but are not limited to this number. For example, the number of openings 26b1 can be two or less, or four or more. When a plurality of openings 26b1 are provided, the interval between the openings 26b1 adjacent in the circumferential direction can be changed as appropriate according to the number and positions of the openings 26b1 to be arranged. Furthermore, the convex portion 28a of the present embodiment is formed by three convex ribs provided at a position corresponding to the opening 26b1 in the top view shown in FIG. 3A, but the convex portion 28a is fitted to the convex portion 28a. It is also possible to form it at other positions in the circumferential direction of the cylindrical portion 28. The convex portion 28a may be an annular convex rib. However, if the projection 28a is provided at a position corresponding to the opening 26b1 in the top view shown in FIG. 3A as in the present embodiment, the mold is set from below through the opening 26b1 during molding. Therefore, it is not necessary to form the convex portion 28a by force. Therefore, if the lower mold and the upper mold are aligned at the position of the convex portion 28a at the time of molding, the convex portion can be surely engaged with the concave portion 34 in the cylindrical portion 31b of the cap member 30 described later. The radial height of 28a can be realized relatively easily.

  Here, FIG. 1 shows an extended state in which the cylindrical second bellows portion 26a is completely extended in the axial direction, and FIG. 2 shows that the cylindrical second bellows portion 26a is completely contracted in the axial direction. The contracted state is shown. As shown in FIG. 1, the cylindrical second bellows portion 26 a of the present embodiment has a shape that decreases in diameter as it goes upward in the axial direction in the extended state shown in FIG. 1. Specifically, the outer diameter and inner diameter of the second bellows portion 26a gradually decrease in the expanded state as it goes upward in the axial direction (increase gradually as it goes downward in the axial direction). Therefore, as shown in FIG. 2, the second bellows part 26a is contracted and deformed by being folded in a direction orthogonal to the axial direction (in the cylindrical second bellows part 26a of the present embodiment, the radial direction). By configuring the second bellows portion 26a as described above, the protruding portion 26 can be more easily pushed inward of the container body 2 than the bellows portion that is folded and contracted in the axial direction. be able to.

  Further, the second bellows part 26a of the present embodiment is in a state of being completely folded in a direction orthogonal to the axial direction by the action of a cylinder part 31b of the cap member 30 described later, that is, in the direction orthogonal to the axial direction. It contracts and deforms to the state of being sandwiched between the bottom plate portion 25. Therefore, in the contracted state of the second bellows part 26a (see FIG. 2), most of the elastic restoring force of the second bellows part 26a acts in the direction orthogonal to the axial direction, and the second bellows part 26a And the bottom plate portion 25 are easily maintained in a state of being sandwiched between them. That is, it is possible to easily maintain the distal end portion 26c of the protruding portion 26 in the pushed-in state shown in FIG.

  In addition, although the lower peripheral wall part 21, the flange part 22, the upper peripheral wall part 23, the seal | sticker cylinder part 24, the baseplate part 25, and the protruding extraction part 26 which form the connection member 20 of this embodiment are integrally molded, Two or more members can be combined and molded.

  The cap member 30 includes a top wall portion 31, a cylindrical wall portion 32, and a cylindrical first bellows portion 33 that connects the top wall portion 31 and the cylindrical wall portion 32. In other words, the cylindrical wall portion 32 is connected to the top wall portion 31 via the cylindrical first bellows portion 33. The cap member 30 is liquid-tightly connected to the container body 2 with the cylindrical wall portion 32 so that the top wall portion 31 covers the protruding extraction portion 26.

  The cylindrical wall portion 32 hangs downward from a cylindrical cylindrical portion main body 32a, an annular flange portion 32b projecting radially outward from the outer surface of the cylindrical portion main body 32a, and a radial outer edge of the flange portion 32b. A cylindrical mounting tube portion 32c concentrically arranged with the tube portion main body 32a, and a seal tube portion 32d suspended downward from the flange portion 32b at a position inside the mounting tube portion 32c. ing.

  On the inner surface of the mounting cylinder portion 32c, a female screw portion 32c1 that is screwed with the male screw portion 23a of the upper peripheral wall portion 23 of the connecting member 20 described above is formed. 1 and 2 show a state in which the cap member 30 is attached to the container body 2 by the male screw portion 23a and the female screw portion 32c1 being screwed and tightened, and in this state, the flange portion 32b The lower surface is in contact with the upper end surface of the upper peripheral wall portion 23. As shown in FIGS. 1 and 2, when the cap member 30 is mounted on the container body 2, the outer surface of the seal cylinder portion 32d is in close contact with the inner surface of the upper end portion of the upper peripheral wall portion 23, and the seal between the two is sealed. Is done. As described above, the cylindrical wall portion 32 of the present embodiment is liquid-tightly connected to the container body 2.

  A portion below the flange portion 32b in the cylindrical portion main body 32a is in a state where the cap member 30 shown in FIGS. 1 and 2 is attached to the container main body 2, and the lower peripheral wall portion 21 and the upper peripheral wall portion 23 of the connecting member 20. It enters into the inside, and the part above the flange part 32b of the cylinder part main body 32a is exposed to a position outside the upper peripheral wall part 23.

  The top wall portion 31 includes a flat top plate portion 31a and a cylindrical portion 31b suspended from the center of the lower surface of the top plate portion 31a. The cylindrical first bellows portion 33 has an upper end thereof. Is connected to the side surface of the top wall portion 31 of the cylindrical portion 31b, and the lower end is connected to the upper end of the cylindrical portion main body 32a. Therefore, the top wall portion 31 is deformed into the cylindrical wall portion 32 by expanding and contracting the first bellows portion 33 in the axial direction (the same direction as the axial direction of the central axis O of the container body 2 in FIGS. 1 and 2). On the other hand, it can move in the coaxial direction with respect to the container body 2 to which the cylindrical wall portion 32 is attached. FIG. 1 shows an extended state in which the first bellows portion 33 is completely extended in the axial direction, and FIG. 2 shows a contracted state in which the first bellows portion 33 is completely contracted in the axial direction.

  Here, the inner diameter of the cylindrical portion 31b is formed to be approximately equal to or slightly larger than the outer diameter at the portion where the convex portion 28a is not formed in the fitting cylindrical portion 28 of the protruding extraction portion 26 described above. Furthermore, the central axis of the cylinder part 31b and the fitting cylinder part 28 is the same as the central axis O of the container body 2 in a state where the cap member 30 is mounted on the connecting member 20 of the container body 2 (see FIGS. 1 and 2). It is in a state of approximately matching. Therefore, the tip part of the cylinder part 31b of the top wall part 31 is fitted with the fitting cylinder part 28 described above by the expansion / contraction deformation of the first bellows part 33 (see FIG. 2), and the fitting cylinder part 28 Both the separated state (see FIG. 1) can be realized. An annular recess 34 that fits with the protrusion 28 a formed on the outer surface of the fitting cylinder portion 28 is formed on the inner surface of the tip portion of the cylinder portion 31 b.

  Moreover, the cylinder part 31b in the top wall part 31 of this embodiment comprises the engaging part engaged with the protruding extraction part 26 in the connection member 20 of the container main body 2. FIG. Specifically, the cylindrical portion 31b of the present embodiment has a projecting tip at the tip when the first bellows portion 33 is changed from the extended state shown in FIG. 1 to the contracted state shown in FIG. The second bellows portion 26a is contracted and deformed by engaging with the protruding portion 26 and following the contraction deformation of the first bellows portion 33.

  More specifically, when the first bellows portion 33 is changed from the extended state (see FIG. 1) to the contracted state (see FIG. 2), the tip of the cylindrical portion 31b of the present embodiment projects as described above. It fits into the fitting cylinder part 28 of the shape extraction part 26. And if the 1st bellows part 33 is further changed to a contracted state, the annular recessed part 34 formed in the inner surface of the front-end | tip part of the cylinder part 31b will be the convex part formed in the outer surface of the fitting cylinder part 28. Fits 28a. Thereby, the cylinder part 31b as an engaging part is engaged with the fitting cylinder part 28 by the undercut and is in a state of being engaged with the fitting cylinder part 28. Therefore, when the first bellows portion 33 is contracted and deformed and the cylindrical portion 31b is pushed inward of the container body 2, the second bellows portion 26a of the protruding portion 26 follows the movement of the cylindrical portion 31b in the axial direction. As a result, the distal end portion 26c can be pushed into the inner side of the container main body 2 (the accommodation space S side). That is, the projecting portion 26 and the cap member 30 can be contracted and deformed by moving the top wall portion 31 downward, and both of them can be changed into a compact shape.

  Conversely, when the cylindrical portion 31b as the engaging portion moves the top wall portion 31 upward to change the first bellows portion 33 from the contracted state (see FIG. 2) to the extended state (see FIG. 1), The state engaged with the protruding portion 26 can be maintained, whereby the second bellows portion 26a can be extended and deformed following the expansion and deformation of the first bellows portion 33. Then, after the second bellows portion 26a reaches the extended state, the first bellows portion 33 is further extended and deformed, whereby the engagement between the cylindrical portion 31b as the engaging portion and the protruding extraction portion 26 is released. . Specifically, in the present embodiment, the engagement between the cylindrical portion 31b and the projecting extraction portion 26a is released when the convex portion 28a comes out of the concave portion 34. Therefore, it becomes possible to separate the cylinder part 31b from the fitting cylinder part 28 (refer FIG. 1). Thus, by the operation of moving the top wall portion 31 upward, the protruding portion 26 and the cap member 30 can be extended and deformed at the same time, and the tip of the protruding portion 26 is more than the upper peripheral wall portion 23. Both can be changed into a use state that protrudes outward and the cap member 30 can accommodate a predetermined amount of the contents Y (see FIG. 4) as a measuring means.

  Accordingly, when not in use, such as during distribution or display, the dispensing container 1 is handled in a compact state by bringing the first bellows portion 33 and the second bellows portion 26a into a contracted state as shown in FIG. be able to. On the other hand, at the time of use, the first bellows part 33 and the second bellows part 26a can be changed to a form that is easy for the user to use by extending the first bellows part 33 and the second bellows part 26a as shown in FIG. Sex can also be maintained. The top plate portion 31a of the top wall portion 31 of the cap member 30 has a cylindrical wall so that the user can easily grip the first bellows portion 33 and the second bellows portion 26a when changing the contracted state to the extended state. It is preferable to protrude outward in the radial direction from the upper end of the portion 32.

  Here, as shown in FIG. 1, the first bellows portion 33 of the present embodiment is in the extended state, like the second bellows portion 26 a, in the axial direction (the central axis O of the container body 2 in FIGS. 1 and 2). In the same direction as the axial direction of the head). Specifically, the outer diameter and inner diameter of the first bellows portion 33 gradually decrease in the extended state as it goes upward in the axial direction (increase gradually as it goes downward in the axial direction). Therefore, as shown in FIG. 2, the first bellows portion 33 is contracted and deformed by being folded in a direction perpendicular to the axial direction thereof (in the radial direction in the cylindrical first bellows portion 33 of the present embodiment). By configuring the first bellows portion 33 as described above, the top wall portion 31 can be more easily pushed inward of the container body 2 than the bellows portion that is folded and contracted in the axial direction. it can.

  Furthermore, the first bellows portion 33 of the present embodiment is completely folded in a direction orthogonal to the axial direction, that is, the cylindrical portion 31b of the top wall portion 31 and the upper end portion of the cylindrical portion main body 32a in the direction orthogonal to the axial direction. It shrinks and deforms until it is sandwiched between the two. Therefore, in the contracted state (see FIG. 2), most of the elastic restoring force of the first bellows portion 33 acts in a direction orthogonal to the axial direction, and the first bellows portion 33 is a cylindrical portion in the direction orthogonal to the axial direction. It is easy to maintain the state of being sandwiched between 31b and the cylinder body 32a. That is, it is possible to easily maintain the top wall portion 31 in the pushed-in state shown in FIG. 2, that is, the protruding ejection portion 26 in the pushed-in state shown in FIG.

  In the present embodiment, both the first bellows portion 33 and the second bellows portion 26a have a shape that is reduced in diameter toward the upper side in the axial direction in the extended state, and are contracted and deformed by being folded in a direction orthogonal to the axial direction. Although it is configured, only one of the bellows portions may have the above-mentioned reduced diameter shape. However, if both the first bellows portion 33 and the second bellows portion 26a have the above-mentioned reduced diameter shape as in the present embodiment, the top wall portion 31 and the container of the cap member 30 pushed into the accommodation space S side. It can further suppress that the protruding extraction part 26 of the main body 2 restores the original state unintentionally.

  In addition, the 1st bellows part 33 and the 2nd bellows part 26a of the extraction container 1 of this embodiment are the expansion | extension states (refer FIG. 1) at the time of shaping | molding, and after attaching the cap member 30 to the container main body 2 By contracting and deforming the first bellows part 33 and the second bellows part 26a, both are set in a contracted state (see FIG. 2).

  When the user uses the cap member 30, the first bellows portion 33 and the second bellows portion 26 a are extended (see FIG. 1) by moving the top plate portion 31 a of the top wall portion 31 upward. Then, the shape of the protruding portion 26 is changed to a usable state.

  Then, as shown in FIG. 4, the cap member 30 is removed from the container main body 2, the container main body 2 is tilted, and the contents Y such as the liquid detergent stored in the storage space S are poured from the projecting extraction portion 26. Take out (see the broken line arrow in FIG. 4) and pour into the cap member 30 as a metering means. In addition, the fold line X of the bellows in the first bellows portion 33 of the cap member 30 of the present embodiment can be used as a measure of measurement. Further, for example, when the amount of the content Y poured into the cap member 30 is larger than the required amount, the accommodation space is provided through the collection passage 27a of the container body 2 and the recovery hole 26a1 formed in the first bellows portion 26a. Can be returned to S.

  The dispensing container according to the present invention is not limited to the configuration specified in the above-described embodiment, and various modifications are possible without departing from the gist of the invention described in the claims. is there. For example, in the dispensing container 1 of the above-described embodiment, the first bellows portion 33 and the second bellows portion 26a have a reduced diameter shape in which the inner diameter and the outer diameter gradually decrease toward the upper side. The 1st bellows part and the 2nd bellows part which have a diameter-reduced shape which a diameter reduces gradually can also be used. However, the contents Y are poured out from the accommodation space S into the discharge path 27 if the inner diameter and the outer diameter are gradually reduced toward the upper side like the first bellows portion 33 and the second bellows portion 26a of the present embodiment. This is useful because it easily flows into the inside. Further, in the dispensing container 1 of the above-described embodiment, the container body 2 is configured by the container body 10 and the connecting member 20, but for example, the container body 2 may be formed by a single member. It is also possible to form a combination of the above members. Furthermore, although the front-end | tip part 26c in the protruding extraction part 26 of the extraction container 1 of embodiment mentioned above is formed in bowl shape, what is necessary is just to form the extraction channel 27 inside, for example, cylindrical shape It is also possible to set it as the front-end | tip part.
