DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a first preferred embodiment of the present invention will be described in detail with reference to FIGS.
Parts having substantially the same functions as those of the conventional example shown in FIGS. 15 to 21 are denoted by the same reference numerals, and detailed description thereof will be omitted. In the figure, (1) shows a container packaged by the packaging container according to the present invention, which is, for example, a medical syringe or the like as in the prior art.

The blister pack (2), which is the main component of the packaging container, is made of a molded product such as vinyl chloride, polyethylene terephthalate, polystyrene or polypropylene, as in the prior art. A pair of mating ribs facing each other is provided on the inner surface of the side wall (3) of the blister pack (2).
(4) is provided so as to protrude inward, and a sealing material (not shown) is attached to the opening (5) of the blister pack (2), so that the contents (1) can be interposed between the fitting ribs (4). The blister pack (2) is hermetically sealed while the container (1) is stably held by fitting.

In such a blister pack, according to the present invention, an oblique beam (8) is provided on the outer surface of the bottom wall (7) of the blister pack (2). It is characterized by the following. The beams (8) are preferably provided on both sides of the fitting rib (4), but may be provided on only one side. On the inclined surface defining the surface of the beam (8), a finger contact mark (9) made of a round projection is formed.

Thus, the bottom wall of the blister pack (2)
By providing the beam (8) in (7), the rigidity of the bottom wall (7) is increased, and the deformation of the side wall (3) connected to this bottom wall is suppressed. Therefore, in a normal state, the distance between the fitting ribs (4) provided on the inner surface of the side wall (3) is unlikely to change, and the container (1) is securely held by the fitting rib (4). The contents (1) do not move or come off in the blister pack (2) due to vibrations during transportation.

When taking out the contents (1), the sealing material is peeled off, the opening (5) of the blister pack (2) is opened, and then the opening (5) is lowered as shown in FIG.
A finger is put on the upper surface of the beam (8) and the end surface of the blister pack (2) at the upper part of (6), and the blister pack (2) is bent by hand in an inverted shape. Due to the deformation, the opening (5) of the blister pack (2) is pushed right and left around the bottom wall (7) reinforced with the beam (8) as shown in FIG. The space between the fitting ribs (4) provided on the side wall (3) is widened, and the contents (1) drop onto the clean table (6) by its own weight.

FIG. 6 shows a modification of the first embodiment.
A syringe (10), which is a stored item, has a structure in which the plunger (11) is separated from the syringe (12), and is connected to the tip of the syringe (12) by the connecting member (13). It is designed to be stored in 2). Because of the structure of the syringe (10), the overall dimensions are shortened, the length of the blister pack (2) is also shortened, and instead of the operation of deforming into an inverted letter with both hands as shown in FIG. Deformation operation with one hand becomes possible. In order to be able to perform the deformation operation satisfactorily with one hand, it is preferable to adopt the structure of the second embodiment described later. However, the thickness of the plastic sheet for forming the blister pack is reduced, and the fitting rib (4) is used. The deformation of the side wall (3) on which is formed may be facilitated. By reducing the thickness of the sheet, it can be easily deformed even with a weak force with one hand, and the storage item (1) can be dropped by widening the gap between the side walls (3) where the fitting ribs (4) are formed. Becomes

FIGS. 7 to 14 show a second embodiment of the present invention. In the first embodiment, the blister pack
In (2), as shown in FIG. 4, the storage item (1) is taken out by holding it with both hands and deforming it into an inverted letter shape. In this second embodiment, one hand is used. The storage object (1) can be taken out to improve usability. With reference to FIGS. 7 to 14, a storage item (1) according to the second embodiment connects a plunger (11) and a syringe (12) as shown in FIG. 6 with a connecting member (13). And a rod-like article such as a syringe with a reduced overall size,
The blister pack (2) is formed to have a shorter length than that shown in FIG. 1 and is dimensioned to be bent and deformed with one hand, suitable for storing such articles.

The blister pack according to the second embodiment
(2) As shown in FIG. 7, both side portions of the side wall (3) on which the fitting rib (4) is formed are formed as oblique tapered surfaces (14) whose widths are reduced toward the center. (14) is formed continuously up to the lower end of the blister pack (2). Other points are substantially the same as the first embodiment. By forming the tapered surface (14), it becomes possible to easily bend the blister pack (2) in an inverted shape along the tapered surface (14). A finger contact groove (17) is formed on the end face (15) of the blister pack (2) and the end face (16) opposed thereto, located on both sides of the recess having the tapered surface (14).
Are engraved multiple times.

In order to take out the stored item, as shown in FIG. 12, a fingertip is applied to the finger contact groove (17) and pressed. By pressing, the blister pack (2) moves along the tapered surface (14),
Side wall which is bent in an inverted shape and has a fitting rib (4)
Since the interval of (3) is widened, the holding of the stored item by the fitting rib (4) is released, and the stored item falls. Instead of pressing with a fingertip, it is also possible to press with a fingertip and palm as shown in FIG. In this way, according to the second embodiment, the blister pack can be deformed with one hand, making it easier to take out the stored items, and possibly causing the stored items to come into contact with the contaminated hand. Further decrease.

In the present invention, the blister pack (2)
Since the beams (8) are provided on the bottom wall (7), the rigidity of the bottom wall (7) increases. Therefore, deformation of the side wall (3) connected to the bottom wall (7) is suppressed, and the container (1) can be firmly held by the fitting rib (4) provided on the side wall (3). .
Also, by bending the blister pack (2) in an inverted letter shape, the interval between the fitting ribs (4) can be surely expanded. It can be dropped from the blister pack (2). Furthermore, beams
Since the (8) is in an oblique shape, a finger is put on the surface of the beam (8) without discomfort and the blister pack (2)
Is easily refracted in the shape of an inverted letter.

The fitting rib (4) as in the first and second embodiments.
If the beam (8) is provided on both sides of the blister, the deformation of the blister pack (2) can be made more reliable, but if only one of the beams (8) is provided, The goal can be achieved. In addition, fingertip mark (9) on the surface of beam (8)
Is provided, the position where the finger is hung can be specified, the operability of the deformation of the blister pack (2) is improved, and the contact between the object (1) and the finger is avoided to avoid contact infection. There are advantages that can be, but not necessarily
There is no need to provide (9). Furthermore, the case where the container (1) is a medical drug is described, but the present invention can also be applied to a packaging container for, for example, stationery or cosmetics.

[0021]

According to the packaging container of the present invention, the space between the fitting ribs can be easily and easily reduced by simply bending and deforming the blister pack in an inverted shape while securely holding the contents in the blister pack. In order to be able to expand precisely,
The contents can be taken out of the blister pack without touching the finger.
