  In the above-mentioned dispensing container, both the inner stopper and the cover cap are attached to the container body only by tightening the cover cap at the same time. At the same time, the inner stopper is aligned with the container body. The mounting process of this is only once, the assembly process can be simplified, and the inner stopper can be mounted on the container body in a predetermined direction. Since the rotation of the inner plug is applied in the opposite direction, the inner plug rotates with respect to the container body. May rotate. In particular, in the invention of the above-mentioned Patent Document 1, since the inner plug abutting portion of the peripheral wall cylinder and the first inner peripheral wall portion and the second inner peripheral wall portion are slidably engaged, the inner plug is removed when the cover cap is screwed off. May also rotate.

  The present invention has been made in view of the above-described points, and both the inner stopper and the cover cap can be attached to the container body, the inner stopper can be fitted and fixed, and the cover cap can be removably attached. It is possible to simplify the process, and there is no inconvenience that the inner plug once fitted does not shift with respect to the container body, and the positioning protrusion of the inner plug is easily fitted into the positioning recess of the container body. The present invention proposes a dispensing container that can be easily assembled.

  The dispensing container of the present invention includes a container body, an inner stopper, and a cover cap. The inner stopper and the cover cap can be attached to the container body all at once, and the inner stopper for the container body is provided. Is configured such that the orientation of the can be aligned with a predetermined orientation.

  The container body is made of a synthetic resin or the like, and has a form in which the mouth and neck are raised from the trunk, and the trunk has a certain direction. When the body portion has a certain direction, it is necessary to adjust the direction of the inner plug with the direction of the container body, for example, so that the nozzle direction of the inner plug is directed to the front of the container body. In the present invention, the inner plug can be fitted and fixed with a predetermined direction with respect to the direction of the container body. On the contrary, the body portion having a certain directionality has a shape other than that which does not change when viewed from any direction, and corresponds to a shape other than a true circle. For example, an object having a cross-sectional shape of an ellipse, a trapezoidal shape, or a shape having a recess on one side surface, etc. This also applies to the case where directionality is given by giving a display or the like.

  The inner plug has a peripheral wall fitted and fixed to the outer periphery of the mouth and neck, and has a spout. For example, from the upper end of the peripheral wall fitted to the outer periphery of the mouth-and-neck part, a form in which a blocking wall part that closes the container body mouth-neck upper-end opening is extended and a spout formed by a pouring cylinder or the like is opened in that part Can be mentioned. In addition, the engagement protrusion provided around the inner periphery of the peripheral wall climbs over and engages with the lower surface of the engagement protrusion provided on the outer periphery of the neck of the container body, thereby preventing upward slipping. In the case of the present invention, the lower portion of the container body neck is formed into a thick portion having a large outer diameter, and a locking protrusion is provided above the thick portion. When providing the locking ridge, the locking ridge may be provided in a form protruding outward from the outer surface of the thick part, or the same height as the thick part or lower than the thick part. It may be formed appropriately, and may be selected as appropriate in light of the protruding width of the thick portion.

  Positioning means for fitting the inner plug to the container body in a predetermined direction is provided between the container body neck and the inner plug. The positioning means is composed of a positioning recess provided at a predetermined position on the outer periphery of the container body neck and a positioning protrusion provided at a predetermined position on the inner periphery of the peripheral wall of the inner plug.

  The positioning recess has a shape in which the upper surface and the outer surface provided in a portion that reaches the part of the thick part by opening the locking protrusion on the outer periphery of the mouth neck portion are open, and the positioning protrusion can be fitted. Various specific shapes can be employed, and examples thereof include a rectangular shape in a front view and a downward trapezoidal shape, and those in which these corners are rounded.

  The predetermined positions where the positioning recesses and positioning protrusions are provided are set so that the inner plug is in the required direction with respect to the container body when they are fitted, but the positioning protrusions are completely fitted in the positioning recesses. In some cases, it is necessary that the engaging protrusion of the inner plug gets over and engages the lower surface of the locking protrusion of the mouth and neck. In addition, the number of positioning recesses and positioning protrusions may be singular or plural, but even in the case of each singularity, for example, the width of each recess and protrusion can be made sufficiently large. It is possible to achieve good fitting stability.

  Moreover, it is good to provide the introduction part which introduces a positioning protrusion in a positioning recessed part continuously. For example, when the cover cap fitted with the inner plug is rotated and lowered and attached to the container body, the introduction portion is formed in a recess shape that is connected to the upper end of the positioning recess on the front side in the rotation direction of the inner plug and the cover cap. Therefore, it is preferable to adopt a configuration in which the upper surface of the wall portion on the front side in the rotation direction is an inclined surface or a curved surface that gradually descends from the front side.

  The cover cap covers the inner plug and is detachably fitted and locked. The cover cap may be configured so that it can be attached to the container body together with the inner plug fixed during assembly. The locked state is preferably screwed to the inner plug, but in that case, for example, the cover cap top wall and the inner plug top wall are arranged to prevent further screwing in the final screwed state. It may be configured to abut and lock.

As the first means of the present invention, the container body A having the locking ridge 5 provided around the outer periphery of the mouth-and-neck portion 3 and the engaging ridge 18 that has been engaged over the lower surface of the locking ridge 5 are provided on the inner periphery. The peripheral wall 10 provided around is fitted and fixed to the outer periphery of the mouth and neck portion 3, and includes an inner plug B having a spout and a cover cap C that covers and fits the inner plug B. 3. A large outer diameter thick portion 3a is formed at the lower outer periphery, and a locking ridge 5 is formed on the upper edge of the thick portion 3a. A positioning projection 20 is formed in a portion that reaches the part of the thick wall portion 3a in the longitudinal direction, and is provided in a positioning recess 6 provided with an introduction portion 7 continuous with the upper end portion. Fitted.

  The dispensing container of the present invention can be fitted and fixed to the neck of the container body by tightening the cover cap with the inner plug fitted inside the container body. Since the cover cap can be attached to the inner plug while being screwed or the like, the assembling process is simplified, and the inner plug can be fitted and fixed to the container body in a predetermined direction. Further, there is no possibility that the fitted inner plug is displaced from the container body.

  In addition, a thick outer portion 3a having a large outer diameter is formed in the lower part of the outer periphery of the mouth and neck portion 3, and a locking ridge 5 is formed above the thick portion 3a. Since the positioning protrusion 20 projecting at a predetermined position on the inner periphery of the inner plug peripheral wall 10 is fitted into the positioning recess 6 formed in a part reaching 3a, the positioning recess 6 can be formed with a sufficient recess width. Thus, the fitting of the positioning protrusion 20 becomes more stable, and there is no possibility of causing a disadvantage such as the positioning protrusion 20 coming off.

  In addition, when the introduction portion 7 that is continuous with the upper end portion of the positioning recess 6 is provided, there is an advantage that the positioning protrusion 20 can be more smoothly fitted into the positioning recess 6.
