Furthermore, an annular mouth member 12 made of resin is fixed to the inner peripheral surface of the upper edge portion 10 . The annular mouth member 12 has a ring shape in plan view, and is a band-shaped ring body having a predetermined dimension in the vertical direction. The lower portion 13 of the annular mouth member 12 is fitted inside the upper edge portion 10 of the container body 2 , and the outer peripheral surface 14 of the lower portion 13 is welded to join the inner peripheral surface 15 of the upper edge portion 10 .

In order to securely weld the lower portion 13 of the annular mouth member 12, two protrusions (annular protrusions in plan view) 14a, 14b are vertically formed on the outer peripheral surface 14 of the lower portion 13.

The upper portion 16 of the annular mouth member 12 extends upward from the upper edge portion 10 of the container body 2 . In addition, an inclined surface (tapered surface) 17 that bulges outward from the top to the bottom is formed on the upper end outer peripheral surface of the upper portion 16 . After the contents are filled into the container body 2 on the factory production line (production line), the inclined surface 17 is transported by the conveying equipment in a state where the lid member 3 is placed, and the lid member 3 is stabilized until the temporary fitting state is formed. , and, as will be described later, the inclined surface 17 functions to facilitate fitting of the cover member 3 and to guide it when the cover member 3 is fitted.

On the outer peripheral surface of the upper portion 16 of the annular mouth member 12, a concave annular surface 18 is formed below the inclined surface 17 so as to have a predetermined width in the vertical direction. Furthermore, a fitting slope 19 whose outer diameter increases from top to bottom is formed on the lower side of the concave ring surface 18 . The fitting slope 19 protrudes outward so as to have a level difference with the concave annular surface 18 and the outer peripheral surface of the lower portion 13 of the annular mouth member 12, and the thick protrusion 20 forming the fitting slope 19 constitutes the annular mouth member. 12 in the first fitting part. A ring-shaped fitting groove 30 is formed at a substantially central portion in the vertical direction of the fitting slope 19 formed on the protrusion 20 .

As described above, the cap member 3 includes the fitting ring portion 8 , the tear-off tape 5 positioned on the fitting ring portion 8 , and the cap main body 6 positioned on the top portion of the snap-off tape 5 .

On the inner peripheral surface of the fitting ring part 8, there are in order from bottom to top a locking protruding part 21, a concave ring part 22 as a second fitting part engaged with the protrusion part 20, and a concave ring part 22 opposite to the concave ring surface 18. Protruding surface 23.

Furthermore, a fitting inclined surface 24 whose inner diameter narrows from the bottom to the top is provided on the upper portion of the protrusion surface 23 , and a protrusion ring 25 is protrudingly provided on the fitting inclined surface 24 . The third fitting portion is formed by the fitting inclined surface 24 and the protrusion ring 25 .

Further, an inner annular portion 29 is formed from the lower surface of the upper panel 26 of the cover body 6 to extend substantially vertically downward from the outer peripheral edge dividing portion 27 of the cover body 6 with a predetermined gap 28 therebetween.

However, as shown in FIG. 2 , in the packaging container of this embodiment, the lid member 3 can be fitted into the temporary fitting state as the first fitting state with respect to the annular mouth member 12 of the container main body 2 .

In the temporarily fitted state, the recessed ring portion 22 formed on the inner peripheral surface of the fitting ring portion 8 of the cover member 3 is fitted to the outside of the protrusion 20 of the annular mouth member 12 .

The fitting of the protrusion part 20 and the recessed ring part 22 is a fitting state to the extent that the fitting state is easily released when a force pushing up is applied to the lid member 3 .

However, when a downward pressing force is applied to the lid member 3 from the state shown in FIG. 2 , the annular mouth member 12 and the lid member 3 are displaced to the second fitting state shown in FIG. 3 , that is, the actual fitting state. .

In the actual fitting state, the protruding part 20 of the annular mouth member 12 and the fitting inclined surface 24 of the fitting ring part 8 are tightly fitted, and the protruding ring 25 formed on the fitting inclined surface 24 Fitted into the fitting groove 30 formed on the fitting slope 19 . Therefore, in this state, the fitting ring portion 8 of the lid member 3 is firmly fitted to the annular mouth member 12 , and it is difficult to remove the lid member 3 from the annular mouth member 12 .

It should be noted that, in the second fitting state shown in FIG. 3 , the upper portion 16 of the annular mouth member 12 enters the gap 28 between the outer peripheral edge dividing portion 27 and the inner annular portion 29 of the cover member 3 . Partially, the annular mouth member 12 and the lid member 3 are also airtightly fitted.

And, by grasping the handle 4 shown by phantom lines and pulling it, the tear-off tape 5 is removed, so that the fitting ring portion 8 of the lid member 3 is kept in a state actually fitted with the ring-shaped mouth member 12, and only The cover main body 6 can be opened by rotating about a hinge part not shown in figure. And, the cover main body 6 can be closed again, and in the state of closing the cover main body 6, the cover main body 6 and the annular mouth member 12 are engaged in the mode that the upper part 16 of the annular mouth member 12 enters the above-mentioned gap 28, so it can pass through the cover. The main body 6 closes an annular mouth member 12 .

The shape of the annular mouth member 12 is not limited to the shape illustrated in FIGS. The structure of the embedded part 31 of the application. In the case of adding the outer fitting part 31, the upper edge part 10 of the container main body 2 is welded in a manner sandwiched by the lower part 13 of the annular mouth member 12 and the outer fitting part 31, so that the container main body 2 and the ring shaped The fastened state of the mouth member 12 is more firm.

In addition, as shown in FIG. 3 , by forming the shape of the outer peripheral surface of the outer fitting portion 31 into the shape of the inner peripheral surface of the fitting ring portion 8 , that is, with the locking protrusion 21 , the concave ring portion 22 and the protrusion surface 23 Therefore, in the actual fitting state (second fitting state), the fitting between the outer surface of the outer fitting portion 31 and the inner peripheral surface of the fitting ring portion 8 can be increased. Thereby, in the actual fitting state (second fitting state), the lid member 3 can be more firmly fitted to the annular mouth member 12 of the container main body 2 .

4 and 5 are partial longitudinal cross-sectional views showing the structure of the main parts of a packaging container according to another embodiment of the present invention. In this embodiment, the ring-shaped mouth member 12 is not welded to the upper edge portion 10 of the container main body 2. An example of a structure in which the annular mouth member 12 is opposed to the outer side of the upper edge portion 10 and welded on the inner side. 4 shows a temporary fitting state (first fitting state), and FIG. 5 shows an actual fitting state (second fitting state).

In FIGS. 4 and 5 , the parts corresponding to the configurations described in FIGS. 2 and 3 are assigned the same reference numerals.

4 and 5 are characterized in that the annular mouth member 12 is not welded to the inner peripheral surface 15 of the upper edge portion 10 of the container body 2 but is welded to the outer peripheral surface 33 . Therefore, two protrusions 14a, 14b for assisting welding are formed vertically on the lower inner peripheral surface 34 of the annular mouth member 12 .

The ring-shaped mouth member 12 is shortened in the vertical direction compared with the previous embodiment (FIG. 2, FIG. 3). And, like the previous embodiment, on the outer peripheral surface of the annular mouth member 12, the inclined surface 17, the concave annular surface 18, the protruding part 20, the outer peripheral surface of the protruding part 20, and The formed fitting slope 19 and the fitting groove 30 provided on the fitting slope 19 .

In addition, the structure of the cover member 3 is the same as that of the previous embodiment ( FIG. 2 , FIG. 3 ).

Even with the configuration shown in FIGS. 4 and 5 , the lid member 3 can be fitted into the temporary fitting state (first fitting state) with respect to the annular mouth member 12 as shown in FIG. 4 . And, in this temporary fitting state (first fitting state), the lid member 3 can be easily detached from the annular mouth member 12 .

Then, when the cover member 3 is pressed downward from the state shown in FIG. 4 , the ring-shaped mouth member 12 and the cover member 3 will be in the actual fitting state (second fitting state) shown in FIG. 5 . In this second fitting state, the fitting ring portion 8 and the annular mouth member 12 are firmly fitted. That is, fitting is performed in such a manner that the fitting slope 24 abuts against the fitting slope 19 and the protrusion ring 25 fits into the fitting groove 30, so that the annular mouth member 12 and the cover member 3 are reliably and firmly fitted. .

In addition, in this embodiment, since the ring-shaped mouth member 12 is not welded to the inner peripheral surface of the container main body 2, it also has the advantage that when the contents (such as granular chewing gum) are taken out from the opening 11, it will not be damaged by the ring-shaped mouth member. 12 stuck, and easy to take out the advantages of the contents.

In addition, there is an advantage that the vertical dimension of the annular mouth member 12 can be shortened, thereby reducing the amount of resin used for the annular mouth member 12 .

6 and 7 are partial longitudinal cross-sectional views illustrating the structure of a main part of a packaging container according to yet another embodiment of the present invention. FIG. 6 shows a temporary fitting state (first fitting state), and FIG. 7 shows an actual fitting state (second fitting state). The embodiment shown in FIG. 6 and FIG. 7 is the same as the embodiment shown in FIG. 4 and FIG. Below the surface, a concave ring portion 35, a convex ring portion 36, and a concave ring portion 37 as a fourth fitting portion are sequentially formed from above toward the bottom, and the concave ring portion 35 and the convex ring portion 36 as a fourth fitting portion And the recessed ring part 37 is for fitting with the protrusion surface 23 formed in the inner peripheral surface of the fitting ring part 8 of the cover member 3, the recessed ring part 22, and the locking protrusion 21.

According to such a structure, the actual fitting state of the fitting ring portion 8 and the annular mouth member 12 is determined not only by the abutment of the fitting slope 19 and the fitting inclined surface 24, but also by the fitting of the fitting groove 30 and the protruding ring 25. Realization is also realized by the fitting of the concave ring portion 35, the convex ring portion 36 and the concave ring portion 37 with the protruding surface 23, the concave ring portion 22 and the locking protrusion 21. Therefore, in the actual fitting state (second In the fitted state), it is more difficult to detach the fitting ring portion 8 (lid member 3) from the annular mouth member 12 (container body 2). Therefore, there is an advantage that the falsification preventing effect of the packaging container is high.

The present invention is not limited to the above-described embodiments, and various changes can be made within the scope of the claims.
