[0028] The attached drawings herein illustrate just embodiments of the present invention and serve to facilitate the general understanding of the scope of the present invention, together with the detailed description of the present invention. Therefore, the present invention is not limitedly interpreted only with the attached drawings.

[0029] FIG. 1 is a side view showing a blister packaging container having a shoulder part-integrated fliptop cap according to the present invention, FIG. 2 is a plan perspective view showing a fliptop cap of the blister packaging container according to the present invention, FIG. 3 is a bottom perspective view showing the fliptop cap of the blister packaging container according to the present invention, FIG. 4 is a front view showing a state where the fliptop cap is open, FIG. 5 is a sectional view showing a state where the fliptop cap is open, and FIG. 6 is a sectional view showing a state where the fliptop cap is closed.

[0030] As shown in FIGS. 1 to 6, the blister packaging container having a shoulder part-integrated fliptop cap according to the present invention includes a container part 100, a shoulder part 200, and a fliptop cap 300.

[0031] The container part 100 is manufactured by heating a sheet, inserting the sheet into a mold, molding an accommodation space, filling contents into the accommodation space of the sheet, attaching a film to the sheet, and cutting the sheet to a predetermined shape.

[0032] In this case, the sheet is made of a plastic laminate material, and the film is attached to the sheet by means of high frequency or ultrasonic rolls.

[0033] The shoulder part 200 is fixedly inserted into the inlet of the container part 100, is hollow at the inside thereof, and passes the contents stored in the container part 100 therethrough.

[0034] Further, the shoulder part 200 has a shoulder concave and convex portion 201 formed along the outer peripheral surface thereof to improve sealing with the inner peripheral surface of the container part 100. Also, the container part 100 has a container concave and convex portion 101 formed along the inner peripheral surface coming into contact with the outer peripheral surface of the shoulder part 200 to improve sealing with the outer peripheral surface of the shoulder part 200.

[0035] The fliptop cap 300 serves to adjust an amount of contents discharged and includes a cap body 310 and a cap cover 330.

[0036] The cap body 310 is a basic body of the fliptop cap 300 connected integrally with the shoulder part 200 and has a discharge hole 311 for discharging the contents therefrom.

[0037] In this case, the discharge hole 311 is conically shaped to decrease the discharging speed of the contents.

[0038] The cap cover 330 functions to open and close the discharge hole 311, is foldably connected to the cap body 310 through a cap hinge 320, and has an opening and closing protrusion 331 inserted into the discharge hole 311 to seal the discharge hole 311.

[0039] Accordingly, the blister packaging container having a shoulder part-integrated fliptop cap according to the present invention is configured to allow the container part 100 to be open and closed multiple times by means of the opening and closing protrusion 331 of the cap cover 330 that opens and closes the discharge hole 311 of the cap body 310 and to prevent an empty space from being formed when the container part 100 is closed again to thus improve the sealing ability thereof.

[0040] As shown in FIGS. 5 and 6, the discharge hole 311 of the fliptop cap 300 includes a locking portion 311a protruding from the inner peripheral surface thereof to compressingly fix the opening and closing protrusion 331 thereto.

[0041] In specific, the locking portion 311a is a stepped portion with a minimum diameter at the inside of the discharge hole 311.

[0042] In a state where the opening and closing protrusion 331 is inserted into the discharge hole 311, accordingly, the locking portion 311a compressingly fixes the opening and closing protrusion 331 thereto, and as the locking portion 311a compresses the opening and closing protrusion 331 inwardly, in this case, the opening and closing protrusion 331 becomes open outwardly to thus come into close contact with the locking portion 311a, thereby improving the sealing with the locking portion 311a. So as to more strengthen the sealing ability between the opening and closing protrusion 331 and the locking portion 311a, in this case, the opening and closing protrusion 331 is made of an elastic material.

[0043] Further, the discharge hole 311 of the fliptop cap 300 includes a guide portion 311b formed on one end into which the opening and closing protrusion 331 is inserted in such a manner as to be enlarged in diameter toward the discharging direction of the contents, and the opening and closing protrusion 331 is enlargedly formed in diameter toward the discharging direction of the contents in the state of being inserted into the discharge hole 311.

[0044] That is, the guide portion 311b is conically shaped, and further, the opening and closing protrusion 331 is conically shaped.

[0045] Further, the guide portion 311b serves to guide the opening and closing protrusion 331 inserted into the discharge hole 311 to the inside of the discharge hole 311.

[0046] According to the configuration of the fliptop cap 300, further, the opening and closing protrusion 331 has a maximum diameter portion 331a smaller than the maximum diameter portion of the guide portion 311b and larger than a minimum diameter portion of the guide portion 311b.

[0047] That is, the diameter of the maximum diameter portion 331a of the opening and closing protrusion 331 is set between the maximum diameter portion and the minimum diameter portion of the guide portion 311b, and if the opening and closing protrusion 331 is inserted into the guide portion 311b of the discharge hole 311, accordingly, the maximum diameter portion 331a of the opening and closing protrusion 331 does not pass through the guide portion 311b, so that the maximum diameter portion 331a of the opening and closing protrusion 331 or a specific portion with a diameter smaller than the maximum diameter portion 331a is seated onto the guide portion 311b.

[0048] According to the configuration of the fliptop cap 300, further, the cap body 310 includes a stepped portion 312 formed steppedly on the edge periphery of one surface where the discharge hole 311 is formed, and the cap cover 330 has a concave portion 332 concavely formed at the inner surface thereof, so that the stepped portion 312 of the cap body 310 is fittedly inserted into the concave portion 332 of the cap cover 330.

[0049] That is, the concave portion 332 is formed concavely on the inner surface of the cap cover 330 facing the cap body 310 in the state where the opening and closing protrusion 331 of the cap cover 330 is inserted into the discharge hole 311 of the cap body 310.

[0050] Accordingly, the fliptop cap 300 has first sealing through the fitting coupling between the concave portion 332 of the cap cover 330 and the stepped portion 312 of the cap body 310 and second sealing through the compressing fixing between the opening and closing protrusion 331 of the cap cover 330 and the locking portion 311a of the discharge hole 311 of the cap body 310, thereby more strengthening the sealing ability thereof.

[0052] As shown in FIGS. 7 to 9, the blister packaging container having a shoulder part-integrated fliptop cap according to the present invention further includes a packaging part 400 and a cut-off line 500.

[0053] The packaging part 400 is extended from the inlet of the container part 100 to sealingly accommodate the fliptop cap 300 therein.

[0054] That is, the packaging part 400 serves to package the fliptop cap 300, and when the contents of the container part 100 are first used by a user, the packaging part 400 is separated and removed from the container part 100 by cutting the cut-off line 500.

[0055] Further, the packaging part 400 is made of the same material as the container part 100.

[0056] The cut-off line 500 is formed on a connection portion between the container part 100 and the packaging part 400, and so as to reduce a cut-off resistance, the sectional area of the cut-off line 500 is smaller than that of the packaging part 400.

[0057] Referring again to FIGS. 7 and 8, the packaging part 400 has an accommodation portion 410 as a space in which the cap hinge 320 is accommodated, and the accommodation portion 410 protrudes outwardly from a given portion of the packaging part 400.

[0058] In this case, the accommodation portion 410 has a curved surface with a given curvature along the given portion of the packaging part 400 and is formed with an arch-shaped section.

[0059] Referring again to FIGS. 5 and 8, the cap hinge 320 includes a first connection portion 321 connected to the cap body 310, a second connection portion 322 connected to the cap cover 330, and a folding portion 323 connecting the first connection portion 321 and the second connection portion 322.

[0060] In this case, the first connection portion 321 and the second connection portion 322 are folded to each other around the folding portion 323, and the folding portion 323 has the shape of a plate.

[0061] Further, the first connection portion 321 and the second connection portion 322 are tapered toward the folding portion 323.

[0062] Moreover, in a state where the first connection portion 321 and the second connection portion 322 are folded to allow the inner surface of the first connection portion 321 to come into contact with the inner surface of the second connection portion 322, the inner surface of the first connection portion 321 is parallel to the inner surface of the second connection portion 322.

[0063] Further, in a state where the first connection portion 321 and the second connection portion 322 are folded to allow the inner surface of the first connection portion 321 to come into contact with the inner surface of the second connection portion 322, the outer surface of the first connection portion 321 is formed as a first inclined surface 321a that is slant from the inner surface of the first connection portion 321, and the outer surface of the second connection portion 322 is formed as a second inclined surface 322a that is slant from the inner surface of the second connection portion 322.

[0064] Referring again to FIGS. 5 and 8, in a state where the first connection portion 321 and the second connection portion 322 of the cap hinge 320 are folded to allow the inner surface of the first connection portion 321 to come into contact with the inner surface of the second connection portion 322, the folding portion 323 is curved with a given curvature, and the first inclined surface 321a and the second inclined surface 322a do not protrude outwardly, so that when the cap hinge 320 is inserted into the packaging part 400, the packaging part 400 can be prevented from being damaged by the cap hinge 320.

[0065] Referring again to FIGS. 2 and 3, further, one surface of the cap body 310 in a horizontal direction is curved, and the other surface thereof in the horizontal direction is flat, so that the cap hinge 320 is horizontally connected to the flat surface of the cap body 310. While the cap body 310 and the cap cover 330 are being folded to each other, accordingly, a pressure applied to the cap hinge 320 located between the cap body 310 and the cap cover 330 can be uniformly distributed to the cap hinge 320.

[0066] FIG. 10 is an exploded perspective view showing other examples of the shoulder part and the fliptop cap of the blister packaging container according to the present invention.

[0067] As shown in FIG. 10, a shoulder part 200 and a fliptop cap 300 are separable from each other. Further, the shoulder part 200 has a should screw thread 202, and the fliptop cap 300 has a cap screw thread 313 formed on the cap body 310 thereof, so that they can be coupled to each other by means of the screw coupling between the should screw thread 202 and the cap screw thread 313.
