  An uneven portion mechanism for preventing cap loosening may be provided between the female screw 53a of the screw tube 53 of the overcap 50 and the male screw 34a of the inner plug 30. For example, a convex portion or a concave portion (not shown) can be formed at the peak portion of the female screw 53a of the overcap 50, and a vertical rib (not shown) can be formed below the male screw 34a of the inner plug 30. It is preferable to provide such uneven portions and vertical ribs at positions near the end of the cap tightening, but by doing so, when the overcap 50 is completely tightened, the vertical ribs get over the uneven portions and are fitted. The click feeling by can also be provided. Furthermore, if the screw cylinder 53 part corresponding to the convex part and the concave part provided in the female screw 53a is formed into a thin wall shape, the structure is easy to bend, and loosening of the overcap 50 can be prevented more advantageously.

  On the inner peripheral side of the lower end edge of the annular inner wall portion 54, a locking protrusion that locks the locking protrusion 43 a formed on the outer peripheral surface of the cylindrical wall portion 43 of the transition plug 40 described above so as to prevent getting over and over. A strip 54a is provided around. That is, when the overcap 50 is attached to the inner plug 30 in a state in which the sealing tube 46 is fitted to the inner plug 30, the cylindrical wall portion 43 is undercut (that is, the locking protrusion 43 a and the engaging ridge 43). It is adapted to be fitted by overcoming the stop protrusion 54a). Note that the center of the ceiling wall portion 51 has a shape slightly bent downward.

  According to such a configuration, the dispensing container 1 can be assembled by the following steps. First, as a first step, the slit valve 60 is attached to the inner plug 30 with the valve pressing member 70. Next, as a second step, the transition plug 40 is attached to the inner plug 30. That is, the sealing tube 46 of the transition plug 40 is fitted to the upper peripheral wall portion 36 (fitting peripheral wall) of the inner plug 30 by getting over the undercut (the locking ridge 36a and the locking ridge 46a). At that time, the protrusion 43b provided around the lower end edge of the cylindrical wall portion 43 of the transition plug 40 is brought into contact with an annular seat surface 37a provided at the upper end of the upper peripheral wall portion 36 (fitting peripheral wall) of the inner plug 30. Thus, it is possible to suppress the action of the load on the planned fracture portion 45 and prevent the planned fracture portion 45 from breaking.

  Next, as a third step, the overcap 50 is attached to the transition plug 40 and the inner plug 30. That is, with the sealing tube 46 fitted to the inner plug 30, the overcap 50 is attached to the inner plug 30, and the tube wall portion 43 is undercut into the overcap 50 (the locking protrusion 43a and the locking protrusion 54a). ). Also at this time, the projection 43b of the transition plug 40 abuts against the seating surface 37a of the inner plug 30, so that the action of the load on the planned fracture portion 45 is suppressed, and the fracture of the planned fracture portion 45 is prevented. .

  In the present embodiment, the projections 43b provided on the lower end edge of the cylindrical wall portion 43 of the transition plug 40 are formed as a pair of protrusions 43b having a semicircular arc shape centering on the axis O of the cylindrical wall portion 43. In this third step, whether or not the space between the sealing pin 41 of the transition plug 40 and the reduced diameter portion 39a of the dispensing tube 39 of the inner plug 30 is properly sealed after the overcap 50 is attached. It is possible to perform a leak inspection for inspecting the above. That is, in such a leak test, air pressure is applied to the lower side (base end side) of the dispensing cylinder 39 to check whether air has leaked to the upper side (leading end side) of the dispensing cylinder 39. However, if appropriate sealing is not performed, air can be leaked through a gap between the pair of protrusions 43b. In addition, the clearance gap between the lower end edge of the cylindrical wall part 43 of the transition plug 40 and the seating surface 37a is made as small as possible to alleviate the impact in each assembly process of the pouring container 1, and This is preferable for preventing breakage of the planned breakage portion 45.

  Finally, as a fourth step, the inner stopper 30 with the transition stopper 40 and the overcap 50 attached is attached to the mouth portion 21 of the container body 20 filled with the contents. That is, the inner plug 30 to which the transition plug 40 and the overcap 50 are attached is fitted to the mouth portion 21 of the container main body 20 by getting over the undercut (the locking protrusion 21a and the locking groove 31a). Also at this time, the protrusion 43b of the transition plug 40 abuts against the seating surface 37a of the inner plug 30, the action of the load on the planned fracture portion 45 is suppressed, and the fracture of the planned fracture portion 45 is prevented. Can do.

  When the user uses the dispensing container 1 with the transition plug assembled and shipped in this way, when the overcap 50 is removed for the first time, the transition stopper 40 is broken at the planned fracture portion 45 as shown in FIG. Therefore, the user can confirm that the container has not been opened by the sound and feel at the time of breaking. The transition plug 40 moves to the overcap 50 side while leaving the sealing tube 46 due to the breakage of the planned breakage portion 45, and thereafter, the discharge tube 39 is sealed together with the overcap 50.

  Then, as shown in FIG. 6, when the container body 20 is tilted and the body portion of the container body 20 is squeezed, the slit 61 of the slit valve 60 is opened, and the contents in the container body 20 are poured out through the dispensing tube 39. be able to.

  As shown in FIG. 1, when the overcap 50 is attached, the sealing pin 41 presses the elastic wall 62 of the slit valve 60 to keep the slit 61 slightly open. During use, the slit 61 is prevented from being fixed due to drying and solidification of the attached contents.

  Next, with reference to FIGS. 7-11, the extraction container with a transition stopper which concerns on other embodiment of this invention is illustrated and demonstrated in detail.

  As shown in FIG. 11, the dispensing container with a transition stopper 1 ′ according to the present embodiment dispenses contents by its own weight simply by tilting the container body 20. That is, as shown in FIGS. 7 to 11, the pouring container 1 ′ with a transition stopper is configured such that the body portion of the container body 20 is not squeezed from the case described with reference to FIGS. 1 to 6. (Which may be configured to be squeezed), does not include the slit valve 60 and the valve pressing member 70, has a larger diameter dimension of the extraction tube 39, and the sealing pin 41 and the top wall portion of the transition plug 40 Although the shape of 42 is different, it is the same configuration in other points.

  In this embodiment, as shown in FIGS. 7 and 8, the sealing pin 41 of the transition plug 40 includes an annular sealing peripheral wall 41b that hangs down from the inner peripheral edge of the flange-shaped top wall portion 42, and the sealing pin 41. It consists of a disc-shaped sealing bottom wall 41c that closes the lower end edge of the wall 41b, and a columnar protrusion 41d that stands at the center of the sealing bottom wall 41c. The outer peripheral surface of the sealing peripheral wall 41 b comes into liquid-tight contact with the reduced diameter portion 39 a formed on the inner peripheral surface of the dispensing cylinder 39.

  According to this structure, it can assemble | attach by the same procedure as the case of the example demonstrated using FIGS. 1-6, and the protrusion 43b of the transition plug 40 is attached to the inside plug 30 like the case of the said example in that case. It is made to contact | abut to the seat surface 37a of this, and the effect | action of the load to the fracture | rupture plan part 45 can be suppressed, and generation | occurrence | production of the fracture | rupture of the plan fracture part 45 can be prevented.

  The above description shows only one embodiment of the present invention, and various modifications can be made within the scope of the claims. For example, the annular seating surface 37a is provided at the upper end of the upper peripheral wall portion 36 (fitting peripheral wall) of the inner plug 30 and the projection 43b is provided at the lower end edge of the cylindrical wall portion 43 of the transition plug 40.
