More specifically, the head portion 33 includes a top wall portion 33a disposed perpendicular to the central axis L, and a peripheral wall portion 33b suspended from the outer edge portion of the top wall portion 33a. The lower end of the head portion 33 is opened toward the opening 30a side of the top wall portion 30, and is communicated from the upper side in the order of the inside of the head portion 33, the inside of the weakened portion 34, and the opening 30a of the top wall portion 30. Yes. The upper end of the head 33 is closed by a ceiling wall 33a, and the container body 2 is sealed by the head 33. The outer diameter of the lower part of the peripheral wall part 33b is gradually enlarged as it goes below.

  The weakening portion 34 is an annular coupling portion interposed between the lower end portion of the head 33 and the inner edge portion of the top wall portion 30, is weaker than other portions such as the head 33, and is the head 33. It is a site | part which can be cut | disconnected by bending (tilting) relatively with respect to the container main body 2. FIG. More specifically, the weakened portion 34 is an annular thin portion, and has a shape in which a substantially triangular cut in the longitudinal sectional view is formed on the outer peripheral surface thereof, and the outer diameter thereof is the head. The diameter is gradually reduced from the lower end of the portion 33 downward. That is, the lower end portion of the weakened portion 34 is the thinnest and can be easily cut.

  Next, the operation of the ampule container 1 having the above-described configuration will be described.

  When the ampoule container 1 is opened, the head 33 is bent relative to the container body 2 in a state where the ampoule container 1 is placed vertically (a state where the mouth portion 23 faces upward). For example, while grasping the trunk | drum 20 of the container main body 2 with one hand, the surrounding wall part 33b of the head 33 is grasped with the other hand, and the head 33 is bent. Thereby, the weakening part 34 is cut | disconnected and the head 33 is cut | disconnected from the site | part of the container main body 2 and the other cap body 3. FIG. Then, when the head portion 33 is cut, the opening 30a of the top wall portion 30 is opened, and the ampoule container 1 is opened.

  At this time, the liquid level of the internal solution X in the container main body 2 may be shaken, and the internal solution X in the container main body 2 may jump along the inner peripheral surface of the shoulder portion 22. Thus, even if the inner solution X jumps up, the inner solution X is blocked by the protrusion 24 and falls into the container body 2 without going toward the mouth 23.

  According to the ampoule container 1 having the above-described configuration, the inner solution X splashed up along the inner peripheral surface of the shoulder portion 22 is blocked by the protruding portion 24, so that the liquid splash of the inner solution X at the time of opening the ampoule container 1 is reduced. Can be prevented.

As mentioned above, although the embodiment of the ampoule container according to the present invention has been described, the present invention is not limited to the above-described embodiment, and can be appropriately changed without departing from the gist thereof.
For example, in the above-described embodiment, the ampule container 1 is manufactured by assembling the cap body 3 having the head portion 33 and the weakening portion 34 to the mouth portion 23 of the container body 2. Although the weakened portion 34 and the weakened portion 34 are separate from each other, in the present invention, the container main body, the head portion, and the weakened portion may be integrally formed. However, when molding such an integrated ampoule container, the ampoule container is molded in a state where an opening is formed at least in the head part 33 (top wall part 30) of the ampoule container or the bottom part 21 of the ampoule container 1. Then, after molding, the contents are filled from the opening, and then the opening is crimped and sealed to seal the ampoule container.

Further, in the above-described embodiment, the protrusion 24 has a curved shape bent in a convex shape toward the inside in the radial direction of the mouth in a longitudinal sectional view, and the outer peripheral surface of the protrusion 24 is the mouth. Although the diameter of the protrusion is smaller than that of the outer peripheral surface of 23, the protrusion of the present invention only has to protrude to the inside in the mouth radial direction, and may be a protrusion having another shape. For example, as shown in FIG. 2, the structure by which the folding | turning part 124 (projection part) was protrudingly provided in the internal peripheral surface of the connection part of the opening part 23 and the shoulder part 22 may be sufficient. The folded portion 124 has a tapered shape that is gradually reduced in diameter as it goes downward from the connecting portion between the mouth portion 23 and the shoulder portion 22, and is formed over the entire inner peripheral surface. According to the ampoule container having the folded portion 124, the internal solution splashed along the inner peripheral surface of the shoulder portion 22 is blocked by the folded portion 124 and falls into the container body 2.
Moreover, the protrusion part of this invention may be formed by enlarging the thickness of the connection part of the opening part 23 and the shoulder part 22 to radial inside.

  Further, in the above-described embodiment, the protruding portion 24 is formed over the entire inner peripheral surface of the mouth portion 23, but in the present invention, the plurality of protruding portions are intermittently disposed in the circumferential direction. Or the protrusion part may be provided only in a part of circumferential direction.

  In the above-described embodiment, the cylindrical head 33 extending upward is provided. However, in the present invention, the shape of the head can be changed as appropriate. For example, a solid columnar head may be used, or a spherical, plate-like, or other shaped head may be used.

  Further, in the above-described embodiment, the weakened portion 34 that is thinned over the entire circumference is formed. However, the present invention is not limited to the thinned weakened portion 34, and the head 33 is used as the container body. Any weakened part that can be cut by moving it relative to 2 may be used. For example, it may be a weakened portion formed intermittently in the circumferential direction of non-penetrating cuts, or may be a weakened portion formed of a material more fragile than the head 33 and the top wall portion 30, Alternatively, by forming the head 33 and the ceiling wall portion 30 separately and joining them by welding or the like, the joint portion can be made a weakened portion.

  In the embodiment described above, the weakened portion 34 is cut by bending the head 33 relative to the container body 2. However, in the present invention, the head 33 is relative to the container body 2. However, it is not limited to the weakened portion 34 that is cut by being bent, and may be a weakened portion that is cut by another operation. For example, a weakened portion that can be threaded by rotating the head 33 relative to the container body 2 may be used.

  In the above-described embodiment, the weakened portion 34 is interposed between the lower end portion of the head 33 and the inner edge portion of the ceiling wall portion 30, but the present invention is along the inner edge portion of the ceiling wall portion 30. Alternatively, a cylindrical rising portion may be provided, and a weakening portion 34 may be interposed between the upper end portion of the rising portion and the lower end portion of the head portion 33.

  Further, in the above-described embodiment, the seal cylinder part 32 fitted inside the mouth part 23 is suspended from the lower surface of the top wall part 30, but the cap body not provided with the seal cylinder part 32 is provided. It is also possible to use it.

  In addition, in the range which does not deviate from the main point of this invention, it is possible to replace suitably the component in above-mentioned embodiment with a well-known component, and you may combine the above-mentioned modification suitably.
