Description

  The present invention relates to a container capable of transferring contents in a filling space to another container, and in particular, a container in which the transfer destination container is a dispenser composed of a syringe (pipette) and a rod. About.

  When dispensing cosmetics, hair styling agents, various drugs, etc., particularly when it is necessary to pour out a small amount and an accurate amount, it is preferable to use a dispenser composed of a syringe and a rod. . Here, when transferring the contents to such a dispenser, the tip of a syringe (for example, an injection needle) is inserted into a container (ampule) filled with the contents, and the rod previously inserted into the syringe is pulled out. In general, the contents in the ampoule are generally sucked into the syringe (see, for example, Patent Document 1).

Japanese Utility Model Publication No. 62-172446

  By the way, such an ampoule is usually a single-use type container filled with the contents of one dose corresponding to the capacity of the dispenser, and therefore, for an dispenser having a different capacity, the capacity is accordingly set. There was a hassle that ampoules had to be prepared. On the other hand, by using a container filled with the contents of a plurality of times, it was also considered to apply the same container regardless of the capacity of the dispenser. It is normal to change depending on the capacity of the container, and once the use is started, there is a concern that the contents in the container may come into contact with the outside air and the like to cause deterioration. The structure of tended to be complicated. Some dispensers allow the contents to be dispensed directly from the through-hole provided at the tip of the syringe without using an injection needle or the like. In such an dispenser, the outer shape of the syringe to be transferred is used. Since the transfer is performed with the syringe inserted into the inner stopper of the container formed together, if the capacity of the dispenser changes, the inner stopper needs to be changed accordingly. The current situation is that the contents are transferred using different containers equipped with inner plugs corresponding to the outer shape.

  An object of the present invention relates to a container that can transfer the contents in a filling space to an extractor, and the same container can be applied to an extractor having a different shape, The present invention proposes a new container that can eliminate the possibility of the contents coming into contact with the outside air as much as possible and can suppress the complexity of the structure of the container.

The present invention is a container that has a filling space for contents, and allows the contents to be transferred to a dispenser composed of a syringe and a rod,
The container has a mouth portion having an opening at the top, and a container body that connects the mouth portion to a barrel portion that rises from the bottom portion to form the filling space inside thereof, and an inner peripheral surface of the barrel portion and a sliding surface. A middle pan that is movable and liquid-tightly contacting and forms the bottom of the filling space; and a middle plug that has a through-opening connected to the filling space and is attached to the mouth,
The inner plug has an inner plug body portion that is suspended and held inside the mouth portion,
The inner plug body includes a stepped peripheral wall that gradually decreases in diameter from the mouth of the container body toward the bottom,
The filling space is closed by leaving the through-opening at the bottom side edge of the stepped peripheral wall, and a plurality of recessed spaces having different diameters are serially formed inside thereof by cooperation with the stepped peripheral wall. The container is provided with a bottom wall to be disposed, and in each recessed space, a syringe corresponding to each diameter can be held in an inverted posture.

The plurality of recessed spaces are composed of two, a small diameter recessed space located on the bottom side of the container body, and a large diameter recessed space located on the mouth side,
In the small-diameter recess space, a stopper provided to be slidable along the axis of the container body is disposed,
The plug body is provided with a ceiling wall that becomes the bottom of the large-diameter recess space at the end of sliding toward the mouth side and becomes the bottom of the small-diameter recess space at the end of sliding toward the bottom side,
It is preferable to provide a through hole in the top wall that allows the filling space and each recessed space to communicate with each other through the through opening.
