  However, in the container, as shown in FIGS. 6 and 7, since the top surface portion 63 of the cap 58 is horizontal, the resistance at the time of extraction is large in the case of a creamy content having a high viscosity. There was a drawback that it was difficult to extract. Further, since there is no portion for storing the extracted contents, it was impossible to extract a certain amount of contents in a drop state of one drop or two drops. The present invention has been made by paying attention to such a conventional problem, and can easily extract a high-viscosity content without a sense of resistance, and can extract a certain amount of the content in a dripping state. An object is to provide a container with a cap.

  According to a first aspect of the present invention, there are provided a container body, an inner plug body that is press-fitted into an opening of the container body, a nozzle cap that covers the inner plug body and is screwed into an opening of the container body. (A) The container body is composed of a body part filled with the contents and a mouth part having an external thread on the outer periphery, and (b) the inner plug body is press-fitted into the mouth part of the container body. It comprises an inner plug body, a ceiling formed above the inner plug body, and an extraction hole drilled in the ceiling. (C) The nozzle cap has an extraction port formed by cutting the upper end. A nozzle part, a protruding cylinder having a nozzle taper part extending in the radial direction from the lower end of the nozzle part, and a cylindrical part having a female screw formed on the lower side of the protruding cylinder and screwed into the male screw of the mouth of the container body It is a container with a nozzle cap characterized by comprising a main body. Since the inner surface of the protruding cylinder of the nozzle cap is formed in a tapered shape, even a highly viscous content can be extracted smoothly along the tapered surface without feeling resistance. In addition, since the nozzle part exists, the extracted contents are once accumulated in the passage of the nozzle part, and the accumulated contents promote the dropping function, and the length of the nozzle and the inner diameter of the nozzle are always determined. A certain amount of contents can be extracted in a dripping state.

  The solution of the invention described in claim 2 is characterized in that a taper portion is formed in the ceiling portion of the inner plug body, and the inclination angles of the upper inner peripheral surface of the taper portion and the nozzle taper portion of the nozzle cap are substantially the same. It is a container with a nozzle cap. Since the inner surface of the protruding cylinder of the nozzle cap is formed in a tapered shape, even a highly viscous content can be extracted smoothly along the tapered surface without feeling resistance. Since the taper part of the ceiling part of the inner plug body and the inclination angle of the upper inner peripheral surface of the nozzle taper part of the nozzle cap are almost the same, the extracted contents remain between the inner plug body and the nozzle cap. Can be prevented.

  According to a third aspect of the present invention, there is provided a container with a nozzle cap, wherein the container body is a bottle container.

  According to a fourth aspect of the present invention, there is provided a container with a nozzle cap, wherein the container body is a tube container.

  According to the present invention, not only liquid content but also high viscosity content can be easily extracted without a sense of resistance, and the content adjusted to a certain amount can be extracted in a dripping state. It has an effect that can be done.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 shows a first embodiment according to the present invention. Reference numeral 1 denotes a container body. The container body 1 is a bottle container or a tube container having a squeeze function, and is manufactured by a known manufacturing method such as blow molding. The tube container is, for example, a single-layer or multilayer blow tube container, a laminate tube container, a double tube container, or the like. The container body 1 includes a body portion 2 and a mouth portion 3, and a male screw 4 is formed in the mouth portion 3. An inner plug body 6 of the inner plug body 5 is press-fitted into the mouth 3, and a locking piece is provided above the inner plug body 6 to prevent the nozzle cap 7 from coming off. A housing 9 that engages with 8 is formed. When the housing 9 is engaged with the locking piece 8, the content flowing out from the extraction hole 11 is prevented from moving to the vicinity of the male screw 4 of the mouth portion 3 which is the downward direction. Above the housing 9, a ceiling portion 12 having a tapered portion 10 having a plurality of extraction holes 11 (four surroundings in the first embodiment) formed in the side surface is formed. In addition, the container main body 1 and the inner plug body 5 may be manufactured by integral molding.

  The nozzle cap 7 has a tip portion 13 cut at the upper end at the YY line when the contents are extracted, and a nozzle portion 14 is formed below the tip portion 13. By determining the length (dimension L in FIG. 2) and the inner diameter (diameter M in FIG. 2) of the nozzle portion 14, the amount of one drop of the content to be extracted can be determined. A protruding cylinder 16 having a nozzle taper portion 15 that extends in a taper shape in the radial direction is formed from the lower end of the nozzle portion 14. In the first embodiment, both the tapered portion 10 of the inner plug body 5 and the inclination angle of the upper inner peripheral surface of the nozzle tapered portion 15 are formed at substantially the same angle. The inclination angle of the upper inner peripheral surface 15a of the nozzle taper portion 15 and the taper portion 10 is 10 ° to 80 °, preferably 30 ° to 60 °. Since the inclination angles are substantially the same, it is possible to prevent the extracted contents from remaining between the inner plug body 5 and the nozzle cap 7. As another example, the inclination angle of the upper inner peripheral surface 15a of the nozzle taper portion 15 and the inclination angle of the taper portion 10 may be different. A cylindrical body 18 having an internal thread 17 is formed below the protruding cylinder 16, and the internal thread 17 of the cylindrical body 18 is screwed with the external thread 4 of the mouth 3 of the container body 1.

  The container with a nozzle cap according to the present invention releases the engagement between the nozzle cap 7 and the ceiling portion 12 of the inner plug body 5 by rotating the nozzle cap 7 screwed into the male screw 4 of the mouth portion 3. When a gap is provided and the bottle container or tube container is pressed by hand, the contents flow into the nozzle portion 14 from the extraction hole 11 of the inner plug body 5. The inflow amount of the contents is determined by the size of the gap between the nozzle cap 7 and the inner plug body 5. That is, as shown in FIG. 4, if the gap between the nozzle cap 7 and the inner plug body 5 is reduced (gap S), a small amount of content flows into the nozzle portion 14. Further, as shown in FIG. 5, if the gap between the nozzle cap 7 and the inner plug 5 is increased (gap T), a large amount of contents can be extracted. The outflow amount can be arbitrarily set in consideration of the viscosity of the contents and the extraction amount. Then, the contents accumulated in the nozzle portion 14 are dropped outside by the dropping function of the nozzle portion 14. If the nozzle cap 7 is reversely rotated and the nozzle cap 7 and the ceiling portion 12 of the inner plug body 5 are engaged, the contents will not flow into the nozzle portion 14.

  As an application example of the present invention, even a highly viscous content can be easily extracted without a sense of resistance, so that a child or an elderly person can easily perform the extraction operation. In addition, since the contents can be extracted in a dropped state by determining the amount of one drop, the bottle container or tube container according to the present invention is filled with not only liquid contents but also creams or ointments with high viscosity. be able to. Therefore, it can be widely used in the fields of food, medicine and the like.
