A screw ring 30 is attached to the nozzle cap 20 so as not to move in the axial direction and is screwed to the mouth portion 12 of the container body 11, and is screwed to the nozzle cap 20 to cover the spout 25 of the nozzle cap 20. And a measuring cap 40. The container main body 11, the nozzle cap 20, the screw ring 30, and the measuring cap 40 can each be configured by resin molding.

  The nozzle cap 20 has a fitting cylinder part 21 fitted on the outer periphery of the upper end of the mouth part 12 of the container body 11 and an outer cylinder part 22 rising upward from the fitting cylinder part 21. On the downward end face of the fitting tube portion 21, there is provided an uneven engagement portion 21A that meshes with and engages with an uneven engagement portion 12A provided on the outer periphery of the mouth portion 12 of the container body 11 (FIG. 3). ). A male screw portion 22 </ b> A is provided on the outer peripheral surface of the outer cylinder portion 22.

  The nozzle cap 20 has an inner cylinder part 23 that extends from the fitting cylinder part 21 and is fitted to the inner peripheral surface of the mouth part 12 of the container body 11. The inner peripheral portion of the inner cylinder portion 23 is a liquid reservoir portion 23A, and a C-shaped cross-sectional pour tube 24 along the edge of the opening 25A provided in the inclined bottom portion 23B of the liquid reservoir portion 23A is raised, and the pour tube Twenty-four C-shaped cuts are slits 25B. A slit 25C connected to the opening 25A and the slit 25B is provided at the bottom of the bottom 23B of the liquid reservoir 23A. The opening 25A and the slits 25B and 25C are the spout 25 of the nozzle cap 20, and also function as an air replacement port during liquid pouring and a liquid return port after liquid pouring.

  The screw ring 30 has an annular protrusion 31A provided on the inner periphery of the upper end of the annular body 31 so as to protrude inwardly between the lower part of the outer cylinder part 22 of the nozzle cap 20 and the upper part of the fitting cylinder part 21. An annular protrusion 22B provided so as to protrude outward continuously around the entire circumference, and a protrusion 22C provided so as to protrude outward at a plurality of positions in the circumferential direction below the male thread part 22A in the outer cylinder part 22 ( 4) and is driven into and inserted into the annular groove 22D. Thus, the screw ring 30 is attached to the outer periphery of the nozzle cap 20 so as to be rotatable and substantially immovable in the axial direction. Further, the screw ring 30 is screwed to a male screw portion 12B provided on the outer periphery of the mouth portion 12 of the container body 11 by a female screw portion 31B provided on the inner periphery of the lower end of the annular body 31.

  The measuring cap 40 is screwed onto the male threaded portion 22A of the outer cylindrical portion 22 of the nozzle cap 20 by a female threaded portion 42A provided on the inner periphery of the outer cylindrical portion 42 provided at the outer peripheral middle portion of the bottomed cylindrical measuring cylindrical portion 41. Worn. At this time, the lower end of the outer cylinder part 42 does not contact the upper part of the screw ring 30.

  However, in the container 10, as shown in FIGS. 3 and 5, the mouth 12 of the container body 11 and the fitting cylinder 21 of the nozzle cap 20 are engaged with each other in the circumferential direction as described above. Engaging portions 12A and 21A are provided. When the female screw portion 31B of the annular body 31 of the screw ring 30 is attached to and detached from the male screw portion 12B of the mouth portion 12 of the container body 11, the engagement of the nozzle cap 20 that is locked in both directions along the axial direction with the screw ring 30. The joining portion 21A is configured to be engaged with and disengaged from the engaging portion 12A of the container body 11. The engagement portion 12A of the container body 11 is provided only at each of the two arcuate portions opposed to the diameter direction of the mouth portion 12 in consideration of the resin moldability. The engaging portion 21 </ b> A of the nozzle cap 20 is continuously provided on the entire circumference of the fitting tube portion 21.

The container 10 is assembled as follows.
(1) The internal thread portion 31B of the screw ring 30 attached to the nozzle cap 20 is fastened to the external thread portion 12B of the container body 11. The slope 102A of the mountain 102 of the engaging portion 21A of the nozzle cap 20 pressed against one side in the axial direction by the screw ring 30 is the slope of the mountain 101 of the engaging portion 12A of the container body 11 in the tightening direction (F). When the screw ring 30 is further tightened, the nozzle cap 20 is stopped and fixed by the engagement of both engaging portions 12A and 21A (FIGS. 6 and 7). ).

  (2) The female screw portion 42A of the measuring cap 40 is screwed onto the male screw portion 22A of the nozzle cap 20. The female screw portion 42A of the measuring cap 40 may be screwed from the beginning to the male screw portion 22A of the nozzle cap 20 described in (1) above.

Therefore, according to the container 10, the following effects are exhibited.
(a) When the screw ring 30 attached to the outer periphery of the nozzle cap 20 so as to be rotatable and locked in both directions along the axial direction is screwed into the mouth 12 of the container body 11 and tightened, The slope 102A of the crest 102A of the engaging portion 21A of the nozzle cap 20 pressed by the ring 30 in one axial direction collides with and engages with the slope 101A of the crest 101A of the engaging portion 12A of the container body 11. When the screw ring 30 is further tightened, the rotation of the nozzle cap 20 is stopped and fixed by the engagement of both the engaging portions 12A and 21A.

  Accordingly, when the measuring cap 40 is grasped and rotated during normal use for extracting the contents from the container 10, even if the nozzle cap 20 is screwed tightly, the nozzle cap 20 is engaged. Due to the above-described engagement between the portion 21 </ b> A and the engaging portion 12 </ b> A of the container body 11, the nozzle cap 20 does not rotate together with the rotation of the measuring cap 40. Thereby, only the measurement cap 40 can be removed, and the contents can be extracted from the spout 25 of the nozzle cap 20. Since there is a gap between the lower end of the outer cylinder part 42 and the upper end of the screw ring 30, the rotational force applied to the measuring cap 40 is not directly transmitted to the screw ring 30, thereby preventing co-rotation more reliably. Is done.

  (b) On the other hand, when refilling the contents into the container 10, if the screw ring 30 is grasped and loosened from the mouth 12 of the container body 11, the axial pressing by the screw ring 30 in one direction is released. As a result, the engaging portion 21A of the nozzle cap 20 can be displaced in the axial direction more than the engaging height with the engaging portion 12A of the container body 11, and as a result, the engaging portions 12A and 21A are disengaged. The nozzle cap 20 is allowed to idle. Thus, the nozzle cap 20 that is also locked in the other axial direction with the screw ring 30 is immediately removed from the mouth 12 of the container body 11 at the same time that the screw ring 30 is removed from the mouth 12 of the container body 11. It is possible to form a wide mouth portion 12 that can be easily removed and refilled.

  Hereinafter, the influence which the shape of the engaging part 12A of the container main body 11 and the engaging part 21A of the nozzle cap 20 exerts on their meshing engagement will be described.

  6A shows an inclined surface 101A on the side where the crest 101 of the engaging portion 12A of the container body 11 and the crest 102 of the engaging portion 21A of the nozzle cap 20 abut on each other in the tightening direction (F). The slope of 102A is made steeper (roughly vertical) than the slope of the opposite slope. According to this, when the screw ring 30 rotates and the slope 101A of the mountain 101 of the engaging portion 12A and the slope 102A of the mountain 102 of the engaging portion 21A collide and tighten, When 102 is engaged with each other and stopped, and the screw ring 30 is further rotated, the crest 101 and the crest 102 in the direction of loosening both the engaging portions 12A and 21A mesh with each other without gaps, and stable engagement is achieved. A state can be secured.

  6B shows an inclined surface 101A on the side where the crest 101 of the engaging portion 12A of the container main body 11 and the crest 102 of the engaging portion 21A of the nozzle cap 20 abut on each other in the tightening direction (F). The slope of 102A is a gentler slope than the slope of the opposite slope. In this case, when the screw ring 30 is rotated, the slope 101A of the mountain 101 of the engaging portion 12A and the slope 102A of the mountain 102 of the engaging portion 21A are brought into contact with each other and tightened. Even if the two engaging portions 12A and 21A are tightened until they cannot be engaged with each other without gaps, the crests 101 and 102 in the direction of loosening the engaging portions 12A and 21A (see FIG. 6B) L) occurs, and a stable meshing engagement state cannot be ensured.

  7A and 7B, in the same manner as FIG. 6A, the crest 101 of the engaging portion 12A of the container body 11 and the crest 102 of the engaging portion 21A of the nozzle cap 20 collide with each other in the tightening direction (F). The slopes of the slopes 101A and 102A on the close side are made to be steeper (generally vertical) than the slopes of the slopes 101B and 102B on the opposite side.

  Furthermore, in FIG. 7, the inclination of the gentle slope 101B of the mountain 101 of the engaging portion 12A and the gentle slope 102B of the mountain 102 of the engaging portion 21A is shown in FIG. The inclination of the screw of the female thread portion 31B of the screw ring 30 was the same. The slope of the gentle slope 101B of the crest 101 of the engaging portion 12A is shown in FIG. 8B with respect to the inclination of the screw of the external thread portion 12B of the container body 11 and the internal thread portion 31B of the screw ring 30. It may be inclined at a large angle θ with respect to the horizontal direction in 20 tightening directions. According to these, when the female thread portion 31B of the screw ring 30 is fastened to the male thread portion 12B of the container body 11, the gentle slope 102B of the engagement portion 21A of the nozzle cap 20 that rotates around the screw ring 30 is engaged with the container body 11. The nozzle cap 20 smoothly moves around the screw ring 30 smoothly without sliding along the upper surface of the gentle slope 101B of the mountain 101 of the portion 12A. The steep slope 102A of the crest 102 of the engaging portion 21A of the nozzle cap 20 is brought into contact with the steep slope 101A of the crest 101A of the engaging portion 12A of the container body 11, and the crest 101 and the crest 102 are engaged with each other. It will reach the meshing engagement state which stops at. When the screw ring 30 is further rotated, the gentle slope 102B of the crest 102 of the engaging portion 21A of the nozzle cap 20 approaches or closely contacts the gentle slope 101B of the crest 101 of the engaging portion 12A of the container body 11 in the axial direction of the screw ring 30. Thus, the crest 101 and the crest 102 are engaged with each other without any gap in the direction of loosening both the engaging portions 12A and 21A, and a stable engagement state can be secured.

  The container main body 11 and the nozzle cap 20 are in meshing engagement with the steep slopes 101A and 102A of the peaks 101 and 102 of the engaging portions 12A and 21A, and the engaging portions of the container main body 11 and the nozzle cap 20 are in engagement. The gentle slopes 101B and 102B of the ridges 101 and 102 of 12A and 21A are in contact with each other in order to securely bring the inner seal part 11S of the container body 11 and the inner seal part 20S of the nozzle cap 20 into close contact with each other, as shown in FIG. It is preferable that a minute gap g is interposed between the gentle slope 101B of the mountain 101 and the gentle slope 102B of the mountain 102.

  Further, the crest 101 of the engaging portion 12A of the container body 11 includes the steep slope 101A and the gentle slope 101B, and the crest 102 of the engaging portion 21A of the nozzle cap 20 includes the steep slope 102A and the gentle slope 102B. Screws 12B, 31B for screwing the container body 11 and the screw ring 30 together with the inclination of the gentle slope 101B of the crest 101B of the engaging portion 12A of the main body 11 and the gentle slope 102B of the crest 102B of the engaging portion 21A of the nozzle cap 20 In the above-described example of FIG. 7 that is set to be the same as the inclination, it is preferable to further include the following configuration. That is, as shown in FIG. 10A, with the nozzle cap 20 to which the screw ring 30 is attached fitted to the mouth portion 12 of the container body 11, the tip of the female thread portion 31B of the screw ring 30 and the container When the tip of the male threaded portion 12B of the main body 11 coincides with the rotational direction of the screw ring 30, the steep slope 102A of the mountain 102 of the engaging portion 21A of the nozzle cap 20 and the intersection 102C of the gentle slope 102B, and the container main body 11 In the state where the steep slope 101A of the mountain 101 of the engaging portion 12A and the intersecting portion 101C of the gentle slope 101B coincide with each other in the rotation direction of the screw ring 30, the steep slope 102A of the mountain 102 of the engaging portion 21A of the nozzle cap 20 The intersection 102C of the slope 102B is the intersection 1 of the steep slope 101A of the mountain 101 and the gentle slope 101B of the engagement portion 12A of the container body 11. Relative 1C, it is assumed that a gap f along the axial direction of the screw ring 30. According to this, when the nozzle cap 20 to which the screw ring 30 is attached is fitted to the mouth portion 12 of the container body 11, the screw ring 30 provided on the outer periphery of the nozzle cap 20 has any rotational attachment position. The female thread part 31B of the screw ring 30 always reaches the male thread part 12B of the container body 11, and the gentle slope 102B of the nozzle cap 20 passes through the gap f described above with respect to the gentle slope 101B of the container body 11. Therefore, when the female thread portion 31B of the screw ring 30 is tightened to the male thread portion 12B of the container body 11, the engagement portion of the nozzle cap 20 that rotates with the rotation of the screw ring 30 as shown in FIGS. The gentle slopes 102B of the ridges 102A of the 21A are not rubbed against the fixed contents of the liquid contents adhering to the gentle slopes 101B of the ridges 101B of the engagement parts 12A of the container body 11, and the peaks of the two engagement parts 12A, 21A. The steep slopes 101A and 102A of 101 and 102 can be smoothly rotated to the meshing engagement position where they collide with each other.

  FIG. 11 is different from FIG. 10 in that the nozzle cap 20 to which the screw ring 30 is attached is fitted to the mouth portion 12 of the container main body 11 and is loose with the steep slope 102A of the mountain 102 of the engaging portion 21A of the nozzle cap 20. The crossing portion 102C of the slope 102B shows a state where there is no gap along the axial direction of the screw ring 30 with respect to the crossing portion 101C of the steep slope 101A of the mountain 101 and the gentle slope 101B of the engaging portion 12A of the container body 11. Is. In this case, when the nozzle cap 20 to which the screw ring 30 is attached is fitted to the mouth portion 12 of the container main body 11, the screw ring 30 depends on the rotational direction attachment position of the screw ring 30 provided on the outer periphery of the nozzle cap 20. The female screw portion 31B does not reach the male screw portion 12B of the container body 11, the gentle slope 102B of the nozzle cap 20 does not pass the above-described gap f with respect to the gentle slope 101B of the container body 11, and the nozzle cap 20 contacts the screw ring 30. It will be something that can't be taken around smoothly.

  Further, in the example of FIG. 10 described above, one or more along the tightening direction of the gentle slope 101B of the mountain 101 of the engaging portion 12A of the container body 11 and the gentle slope 102B of the mountain 102 of the engaging portion 21A of the nozzle cap 20 is used. In the meshing engagement state (FIG. 10D) in which the steep slopes 101A and 102A of the peaks 101 and 102 collide with each other, for example, at two positions, they are locked in the anti-tightening direction. The matching locking step portions 101D and 102D were provided. According to this, in the above-described meshing engagement state in which the steep slopes 101A and 102A of the peaks 101 and 102 of the engaging portions 12A and 21A of the container main body 11 and the nozzle cap 20 are brought into contact with each other, the peaks 101 and 102 are formed. When the gentle slopes 101B and 102B of each other pass through the above-mentioned minute gap g (FIG. 9), a loosening stopper having a step height h higher than the above-mentioned minute gap provided on the gentle slopes 101B and 102B of the peaks 101 and 102. The step portions 101D and 102D are engaged with each other to reliably prevent the rotation in the direction of loosening both the engaging portions 12A and 21A.

  In the present embodiment, the engaging portion 12A of the container body 11 and the engaging portion 21A of the nozzle cap 20 are configured by ridges 101 and 102, and the ridge 101 is composed of a combination of both side slopes 101A and 101B at the top. 102 is made of a combination of both side slopes 102A and 102B at the top. However, any one of the engaging portion 12A of the container main body 11 and the engaging portion 21A of the nozzle cap 20 may be one in which both sides of the top portion are inclined, and the other is a flat surface or an arcuate surface. It can also consist of the convex engaging part standing upright so that the both sides of a top part may become a substantially vertical wall surface, and the same effect is acquired.

  Further, the number of engaging portions 12A and engaging portions 21A provided in the circumferential direction of the container body 11 and the nozzle cap 20 can be increased or decreased. In particular, by reducing the number of the engaging portions 12A and the engaging portions 21A and providing the engaging portions 12A and 21A at, for example, two locations in the circumferential direction of the container body 11 and the nozzle cap 20, the nozzle cap 20 with respect to FIG. When the cross section of the container body 11 is an ellipse in a specific direction, for example, the nozzle cap 20 can be aligned with the major axis direction of the ellipse of the container body 11. Furthermore, if the engaging portions 12A and 21A are provided at, for example, one place in the circumferential direction of the container body 11 and the nozzle cap 20, the nozzle cap 20 can be determined not only in the direction with respect to the container body 11 but also in a specific direction. In addition, the spout 25 of the nozzle cap 20 can be positioned in a specific direction with respect to the container main body 11, and the user-friendly container 10 can be provided.
