MODES OF THE INVENTION

Hereinafter, the overall configuration and operations according to exemplary embodiments of the present invention will be described. Such embodiments do not restrict the overall configuration and operations, and a case in which other configurations and operations which are not clearly described in the embodiments are easily understood by those skilled through the embodiments of the present invention will be considered as the technical spirit of the present invention.

Generally, ampoules or vials are containers which may be formed of a glass or plastic material. In the case of an ampoule, since a melting and sealing process of melting and sealing the mouth of a container is performed after the container is filled with a drug, productivity may be increased. However, in a case in which a container body or container stopper part is formed of a plastic material, a method is needed to increase productivity in processes of filling a drug and sealing a container when compared to the ampoule formed of the glass material.

FIG.1is a side cross-sectional view illustrating a container which accommodates a drug and is sealed.

Referring toFIG.1, the container, which accommodates a drug and is sealed, of the present invention includes a container stopper part100and a container body200. A protrusion202is formed in the container body200, a curved portion203is formed so that a head portion205is formed on a cut portion204, and a state in which the container stopper part100seals the container body200is shown.

FIG.2is a view illustrating a shape of the container, which accommodates a drug and is sealed, of the present invention to be filled with a drug,FIG.3is an enlarged view illustrating the container stopper part of the container, which accommodates a drug and is sealed, of the present invention,FIG.4is an enlarged view illustrating the head portion of the container, which accommodates a drug and is sealed, of the present invention.

Referring toFIGS.2and3, a state in which the container stopper part100seals the container body200to accommodate a drug and a form in which the container stopper part100is inserted into an opening201of the container body200are shown,

Filling grooves101formed in an outer surface of the container stopper part100form a passage through which the drug may enter an inner portion of the container body200from the outside even in the state in which the container stopper part100is inserted into the opening201of the container body200, when the container body200is filled with a predetermined amount of the drug, the container stopper part100is moved further into and press-inserted into the container body200so that a cover part104is in contact with the opening201.

Referring toFIGS.2and4, in a case in which a user wants to use the drug filling the container body200, the head portion205is separated from the container body200so that the drug flows from the container body200.

In order to separate the head portion205from the container body200even using only a finger force of the user without using a particular tool to separate the head portion205from the container body200, the cut portion204is formed between the head portion205and the container body200.

Meanwhile, since the cut portion204is formed, the head portion205may be easily separated from the container body200. However, the cut portion204may also be broken, and the drug may flow out when the container of the present invention is stored or transported.

In order to prevent such breakage, when the curved portion203is formed between the container body200and the cut portion204, resistance against a force vertically applied from an upper side of the container body200may be increased.

More specifically, as a large number of containers in which drugs are accommodated are packed in a box and a large number of boxes may be stored or transported, there is a case in which the boxes are stacked in several layers when stored or transported, and in this case, when a force vertically applied from the upper side of the container body200is increased to a certain magnitude, the cut portion204may be broken, and the drug may flow from the container.

As a result, when the curved portion203is formed between the container body200and the cut portion204, the resistance against the force vertically applied from the upper side of the container body200can be increased, and the user can easily separate the head portion205from the container body200in a case in which the user applies a force in a diameter direction of the container body200to use the drug filling the container body200.

FIGS.5A,5B, and5Care top, side, and bottom views illustrating the container stopper part of the container, which accommodates a drug and is sealed, of the present invention, andFIG.6is a view illustrating specific dimensions of the container stopper part of the container, which accommodates a drug and is sealed, of the present invention.

Referring toFIGS.5A,5B, and5C, in the container stopper part100of the present invention, a first seating portion102and a second seating portion103which are pushed into the container body200are formed, and a diameter of the cover part104is formed to be greater than a diameter of the second seating portion103so that the container stopper part100is inserted into and seals the container body200and the cover part104is in contact with the opening201.

In addition, the filling grooves101are formed in an outer wall surface of the container stopper part100, five filling grooves101are formed to have a semicircular shape as shown inFIG.5Aand formed in the first seating portion102and the second seating portion103as shown inFIG.5B. The plurality of filling grooves101may be formed in the outer wall surface of the container stopper part100, since a filling speed may be significantly improved when filling the container with the drug, an increase in productivity can be expected, and in a case in which the container stopper part100is manufactured through injection molding, since a mold may be simplified, manufacturing costs can be reduced.

When a cross-sectional area of the filling groove101formed to have the semicircular shape is greater than a predetermined area, since the drug may not stay in the container and may flow out of the container after the container is filled with the drug in a vacuum filling method, it is difficult to perform a subsequent sealing process.

As a result, the cross-sectional area of the filling groove101should be smaller than the predetermined area, but as the cross-sectional area of the filling groove101decreases, a filling speed may decrease when filling the container with the drug. Therefore, in the present invention, the plurality of filling grooves101may be formed in the outer wall surface of the container stopper part100and thus the filling speed can increase due to all of the plurality of filling grooves101.

In addition, a groove105is formed between the first seating portion102and the second seating portion103, and the groove105is a part in which the protrusion202formed on an inner wall of the container body200is seated. The groove105will be described in detail in the description aboutFIG.7.

Referring toFIG.6, the container stopper part100includes the first seating portion102and the second seating portion103which are inserted into the opening of the container body200, and an outer diameter d1of the first seating portion102is formed to be smaller than an outer diameter d2of the second seating portion103.

FIGS.7A,7B, and7C, are views illustrating a process in which the container, which accommodates a drug and is sealed, of the present invention is filled with a drug and sealed according to a position of the container stopper part.

Referring toFIGS.7A,7B, and7C,FIG.7Ashows a state in which the container stopper part100is separated from the container body200,FIG.7Bshows a state in which the container stopper part100is combined with the container body200, the first seating portion102is inserted into the container body200through the opening201of the container body200so that an end of the first seating portion102is in contact with the protrusion202formed on the inner wall of the container body200, and an end of the second seating portion103is positioned in the opening201of the container body200.

The container may be filled with the drug in an operation of filling the drug illustrated inFIG.7Bthrough a vacuum filling method, and after the filling is completed, as illustrated in FIG.7C, the second seating portion103of the container stopper part100is press-inserted into the container body200through the opening201of the container body200, the first seating portion102passes the protrusion202and further enters the inner portion of the container body200, and the protrusion202formed on the inner wall of the container body200is seated in the groove105formed between the first seating portion102and the second seating portion103of the container stopper part100.

As illustrated inFIG.7C, after the container stopper part100is completely press-inserted into the container body200, fusion may be performed, an outer portion of the container is cleaned, and post-sterilization is performed.

In addition, the container stopper part100and the container body200of the present invention may be manufactured through injection molding, a cross section thereof may be formed to have an oval or track shape, but it is preferable that the cross section be formed to have a circular shape in order to effectively arrange and handle the plurality of containers in a process of filling the drug and cleaning.
