Japanese Patent No. 3477079

  However, the following problems remain in the conventional ampoule. That is, in the conventional ampoule, burrs may occur on the opening periphery of the mouth when the break is broken. And this burr | flash has the problem that the handleability of the ampule at the time of taking out the content falls. Further, there is a possibility that the fracture portion is broken by an unexpected external force applied to the ampoule during the distribution process.

  The present invention has been made in view of the above-described problems, and an object thereof is to provide an ampoule that is easy to handle and that suppresses breakage of the breakage part inadvertently in the course of distribution.

The present invention employs the following means in order to solve the above problems. That is, the ampoule of the present invention includes a bottomed cylindrical container main body that contains the contents, and a head that is connected to the mouth of the container main body via a breakable portion and seals the mouth. An overcap that is detachably attached to the container main body and covers the mouth, the fracture portion, and the head, and the top plate of the overcap has an inner side along the axial direction of the container main body. to extend toward the cylindrical portion having an insertable outer diameter to the opening portion is provided with an opening in the top plate portion, said overcap, said remove the head and remove the said overcap After being mounted on the container main body again after moving toward the inner side along the axial direction with respect to the container main body from the mounting position on the container main body before the head is removed, The cylinder part can be inserted into the mouth part. And said that you are.

In the present invention, when the overcap is attached to the container body again after the head is removed and moved toward the inner side in the axial direction of the container body, the tube portion is inserted into the mouth portion. For this reason, even if the burrs are generated at the opening peripheral edge of the mouth after breaking the break portion, the burr can be covered with the top plate portion by inserting the tube portion into the mouth. And the user can take out the content, without touching the said burr | flash, by taking out the content in a container main body through the opening part in the top-plate part of a cylinder part.
In addition, since the mouth, the rupture part and the head are covered with the overcap, even if an unexpected external force is applied to the ampoule during the distribution process, this external force is received by the overcap and an external force is applied to the rupture part. Can be suppressed.

Moreover, it is preferable that the ampoule of this invention is provided with the plug body which plugs the opening part in the said top-plate part of the said cylinder part.
In the present invention, even after the head is removed once and the ampoule is opened, the opening in the top plate portion of the tubular portion can be closed, so that the content can be stored without having to use up the content all at once. For this reason, it can prevent that the kind of content accommodated in a container main body is limited.

In the ampoule of the present invention, it is preferable that the plug is connected to the overcap via a hinge portion.
In this invention, since the plug is integrated with the overcap, the opening / closing operation of the plug is facilitated.

  According to the ampoule according to the present invention, the contents in the container body can be taken out without touching the burrs by taking out the contents in the container body through the opening in the top plate portion of the cylindrical portion, and the handleability is improved. Moreover, even if an unexpected external force is applied to the ampoule, it is possible to suppress the external force from being applied to the fractured portion by receiving the external force with the overcap.

Hereinafter, an embodiment of an ampoule according to the present invention will be described with reference to the drawings. In each drawing used in the following description, the scale is appropriately changed so that each member can be recognized.
As shown in FIG. 1, the ampoule 1 according to the present embodiment includes a container body 11, a head 12, and an overcap 13 that contain contents C such as liquid, powder, granules, and paste.
In addition, the container main body 11, the head 12 and the overcap 13 are each formed in a cylindrical shape, and the respective central axes are located on a common axis. Hereinafter, this common axis is referred to as a central axis (container body axis) O. In the present embodiment, the overcap 13 side along the central axis O is referred to as “upper side”, and the opposite side is referred to as “lower side”. Furthermore, in the present embodiment, a direction orthogonal to the central axis O is defined as a “radial direction”.

The container body 11 is integrally formed of, for example, a synthetic resin, and has a bottomed cylindrical trunk portion 21, a shoulder portion 22 whose diameter is reduced from the upper end of the trunk portion 21 upward, and a shoulder portion 22. And a mouth portion 23 extending to the upper end of the head.
The trunk | drum 21 has comprised the substantially cylindrical shape. On the outer peripheral surface in the vicinity of the upper end of the body portion 21, an engaging convex portion 24 that engages with an engaging concave portion 34 described later formed in the overcap 13 is provided over the entire circumference.
The inside of the mouth portion 23 communicates with the inside of the container main body 11. Hereinafter, the radially inner side of the mouth portion 23 is referred to as an extraction hole portion 25.

The head portion 12 is a hollow member having a top cylindrical shape with an open lower end. Further, the head 12 extends upward from the periphery of the extraction hole 25 of the mouth 23. The head portion 12 is connected to the mouth portion 23 via a fracture portion 28 and seals the container body 11.
The fracture portion 28 is formed by making its thickness sufficiently thinner than the mouth portion 23 and the head portion 12. Therefore, the breaking portion 28 is easily broken by an operation such as pushing down, pulling, or twisting the head 12 while holding the container body 11.

The overcap 13 has a cylindrical shape, and includes a peripheral wall portion 31, a top plate portion 32 provided at the upper end of the peripheral wall portion 31, and a plug body 33 that closes the top plate portion 32.
The peripheral wall portion 31 has a substantially cylindrical shape, and the inner diameter is substantially equal to the outer diameter of the body portion 21. On the inner peripheral surface of the lower portion of the peripheral wall portion 31, an engagement concave portion 34 that engages with the engagement convex portion 24 is provided over the entire circumference.

The top plate portion 32 is substantially circular in plan view. An opening (an opening in the top plate portion of the cylindrical portion) 35 is formed at the center of the top plate portion 32. In addition, a cylindrical portion 36 that protrudes downward and surrounds the periphery of the opening 35 is provided on the lower surface of the top plate portion 32. In addition, an accommodation groove portion 37 that accommodates the plug 33 is formed on the top surface of the top plate portion 32. The length of the accommodation groove portion 37 in the radial direction is longer than the length of the plug body 33 in the radial direction. Therefore, a gap is formed between the edge on the central axis O side of the housing groove 37 and the edge on the central axis O side of the plug 33. Then, a fingertip is inserted into the gap to open the plug 33.
The cylindrical portion 36 has an outer diameter substantially equal to the inner diameter of the extraction hole portion 25 and can be inserted into the extraction hole portion 25. As a result, the outer surface of the cylindrical portion 36 and the inner surface of the extraction hole portion 25 are pressed in a liquid-tight manner. Further, the length of the cylindrical portion 36 is such that the lower end of the cylindrical portion 36 does not contact the upper end of the head 12 in a state where the engaging concave portion 34 of the overcap 13 is engaged with the engaging convex portion 24 of the container body 11. And it is a grade longer than the thickness of the mouth part 23.

The plug 33 has a substantially band shape in a plan view, and extends from the radial outer edge of the top plate 32 to the center of the top plate 32 in a state of being accommodated in the accommodation groove 37. Further, an end portion on the radially inner side of the plug body 33 is provided with a closing convex portion 38 that is fitted in the opening portion 35 and closes the opening portion 35 in a state of being accommodated in the accommodation groove portion 37. Further, the radially outer end of the plug 33 is connected to the radially outer edge of the top plate 32 via a hinge 39.
The thickness of the hinge portion 39 is sufficiently thinner than the plug 33 and the top plate portion 32. For this reason, the plug body 33 is rotatably disposed around the hinge portion 39 so as to approach and separate from the top plate portion 32 in the vertical direction.

  Next, a method for using the ampoule 1 will be described. First, after the user removes the overcap 13, the user breaks the breaking portion 28 by, for example, pushing down the head portion 12 while holding the container body 11, and removes the head portion 12 from the container body 11 to take out the extraction hole portion. 25 is opened (see FIG. 2). At this time, burrs may be formed on the periphery of the extraction hole 25.

  Then, the overcap 13 is again attached to the container body 11 (see FIGS. 3 and 4). Here, since the head portion 12 is removed, the overcap 13 can be pushed downward with respect to the container main body 11 sufficiently more than the position where the engaging concave portion 34 engages with the engaging convex portion 24. Therefore, when the peripheral wall portion 31 of the overcap 13 is pushed in the direction of the central axis O along the outer peripheral surface of the trunk portion 21 of the container body 11, the cylindrical portion 36 is inserted into the extraction hole portion 25, and the lower end thereof is The container body 11 is reached. And the burr | flash which may be formed in the periphery of the extraction hole part 25 is not exposed outside by being covered with the overcap 13. At this time, the closing projection 38 of the plug 33 is engaged with the opening 35 and closes the opening 35.

  Thereafter, the plug body 33 is rotated upward with respect to the top plate portion 32 of the overcap 13 around the hinge portion 39 to release the engagement state between the closing convex portion 38 and the opening portion 35. Is opened (see FIGS. 5 and 6). Thereby, the cylinder part 36 connects the inside of the container main body 11 and the outside of the ampoule 1. And a user takes out the content C in the container main body 11 outside through the cylinder part 36 and the opening part 35. FIG. At this time, since the upper end of the container body 11 is covered with the overcap 13, the user does not touch the burrs that can be formed on the peripheral edge of the extraction hole portion 25 by breaking the breaking portion 28. Moreover, since the other end part is integrated with the top-plate part 32 via the hinge part 39, the plug body 33 is not lost while taking out the contents.

  And when the contents C in the container main body 11 are not used up at once, the container main body 11 is closed by engaging the closing convex part 38 of the stopper 33 with the opening 35, and the contents C You can save.

According to the ampoule 1 having such a configuration, the content C in the container body 11 is taken out through the opening 35 of the cylindrical portion 36, and the content C is taken out without touching the periphery of the take-out hole 25. Can do. For this reason, the handleability of the ampule 1 is improved. Even if an unexpected external force is applied to the ampoule 1, it is possible to prevent the external force from being applied to the fracture portion 28 by receiving the external force with the overcap 13.
And since the stopper 33 closes, it is not necessary to use up the content C at once, and the kind of the content C accommodated in the container main body 11 can be increased. Further, since the plug body 33 is integrated with the overcap 13, the plug body 33 is not lost, and the handleability of the plug body 33 is improved.

In addition, this invention is not limited to the said embodiment, A various change can be added in the range which does not deviate from the meaning of this invention.
For example, the outer diameter of the cylindrical portion may be smaller than the inner diameter of the extraction hole portion in the case of, for example, a tablet that can be handled without liquid tightness.
In addition, in the state where the tube portion is inserted into the take-out hole portion, the lower end of the tube portion is protruded into the container body. However, the lower end of the tube portion may be positioned in the take-out hole portion without protruding into the container body. Good.
The overcap is configured to slide downward along the trunk in the direction of the central axis. A female screw is formed on the inner peripheral surface of the overcap and a male screw is formed on the outer peripheral surface of the trunk. The overcap may be moved downward in the direction of the central axis by screwing the overcap into the body portion by forming.

Moreover, although the hinge part is formed by making the wall thickness thinner than each of the plug body and the top plate part, other structures may be used.
And although the plug is connected to the top plate by the hinge, it is not limited to the top plate and may be a peripheral wall.
Furthermore, although the plug body is integrally formed with the top plate portion by the hinge portion, it may be a separate body without being connected to the top plate portion by the hinge portion.
Further, as the plug body, it is also possible to employ a cylindrical cap or a rod-shaped plug that is not connected by a screw cap or a hinge portion but simply inserted into the opening.
For example, when the contents are used up at once, the plug body need not be provided.
Furthermore, the head is not limited to being hollow and may be solid.

  According to the present invention, industrial applicability is recognized for an ampoule that has good handleability and that suppresses breakage of the breakage part inadvertently during distribution.
