Description

[Technical field]

[0001] The present invention relates to a rotating opening and closing structure for a lid of a packaging container having a non-circular injection port, which enables the lid of a packaging container having a non-circular injection port, including a polygonal one, to be easily opened and closed in a rotating manner as if the lid were opened and closed on the outer peripheral surface of a circular type. [Background technology]

[0002] Generally, various packaging containers including cosmetic containers are provided with an injection port, and the opening and closing method of the lid (including the cover) varies depending on the shape of the injection port.

[0003] Typically, when the injection port has a circular shape, the lid is opened and closed by rotating the lid relative to the circular injection port using a method such as screwing, and when the injection port has a non-circular shape, including a polygonal injection port, the lid is opened and closed mainly by an undercut method, in which the lid is opened and closed in the vertical direction relative to the injection port.

[0004] Therefore, conventionally, injection ports have been circular mainly for the convenience of opening and closing the lid, and non-circular types have not been offered. In consideration of the design of the lid, only non-circular external shapes of the lids have been offered.

[0005] In addition, because the injection port of the packaging container is of a circular type, consumers are accustomed to opening and closing the lid by a rotating method such as screwing. [Prior art documents] [Patent documents]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

[0017] Referring to Figures 1 to 9, the rotating opening and closing structure of a lid for a packaging container having a non-circular type injection port according to the present invention includes a packaging container 110 having a non-circular type injection port 114, including a polygonal type, and a lid 120 that opens and closes the injection port of the packaging container using a rotating opening and closing method.

[0018] The packaging container 110 has a packaging space 112 with one side open so that various packaging contents can be accommodated therein.

[0019] An injection port 114 formed at the open end of the packaging space 112 is extended inwardly in a stepped shape.

[0020] The inlet 114 may have various shapes, such as a square as shown in the drawings, other polygonal shapes, or non-circular shapes.

[0021] According to the present invention, when the shape of the injection port 114 of the packaging container 110 is a non-circular type, such as a polygonal type, as described above, there are significant structural limitations to realizing the lid to be opened and closed by rotating as in the conventional method.

[0022] Therefore, the technical feature of the present invention is that it has been developed to enable the lid 120 to be easily opened and closed in a rotating manner for a packaging container 110 having a non-circular type injection port 114, including a polygonal type, as described below.

[0023] For this purpose, in the present invention, one or more first opening prevention ribs 116 are provided protruding vertically at appropriate intervals on the outer peripheral surface of the injection port 114 of the packaging container 110 which is of a non-circular type including the polygonal type, and one or more first engagement pieces 118 having an outer surface 119 which narrows in the opening direction of the lid are arranged between the first opening prevention ribs 116 so as to protrude horizontally at appropriate intervals.

[0024] In addition, on the inner surface of the lid 120, which is open on one side, a second opening-inhibiting rib 122 is formed to protrude vertically relative to the first opening-inhibiting rib 116 formed on the injection port 114 of the packaging container 110, and is engaged and released in an alternating manner when the lid is opened and closed.In addition, a second locking piece 124 is protruded horizontally between the second opening-inhibiting rib 122 and the first locking piece 118, and is forcibly engaged and released from the first locking piece 118.

[0025] Meanwhile, the first and second locking pieces 118, 124 formed on the outer peripheral surface of the injection port 114 and the inner peripheral surface of the lid 120, respectively, have been described as being formed to protrude horizontally for stable locking and unlocking operations when the lid is opened and closed. However, as long as they perform the same locking and unlocking functions, they are not limited to this terminology, and may have different horizontal angles, such as a shape formed to be inclined in the closing direction of the lid.

[0026] In addition, the first and second open-restraint ribs 116 and 122 are configured to suppress any arbitrary opening operation of the lid 120 after the closing operation of the lid 120 on the injection port 114 of the packaging container 110 is completed, and as long as the function can be achieved, they are not limited to the terminology, and various modifications such as locking protrusions and locking grooves other than the rib shape are possible.

[0027] According to the rotating opening and closing structure of the lid for a packaging container having a non-circular type injection port of the present invention configured as described above, even if the injection port 114 of the packaging container 110 is of a non-circular type such as a polygonal type, the opening and closing operation of the lid 120 can be performed by rotating and opening in the same manner as a conventional circular type injection port. The rotating opening and closing structure of the lid 120 for the injection port 114 of the packaging container 110 will be described below.

[0028] First, refer to FIG. 8. FIG. 8 shows a state in which the lid 120 is rotated to a closed position relative to the injection port 114. In this state, the second opening suppression rib 122 formed on the inner peripheral surface of the lid 120 is elastically locked in a staggered state with respect to the first opening suppression rib 116 formed on the outer peripheral surface of the injection port 114, so that a stable locked state is maintained unless the lid body 120 is opened by applying an external force to a part of it, and therefore, any arbitrary opening operation of the lid can be prevented or suppressed. Then, the first locking piece 118 formed on the injection port 114 and the second locking piece 124 formed on the inner peripheral surface of the lid 120 are in a mutually locked state.

[0029] Therefore, in the state shown in FIG. 8, the lid 120 is forcibly closed on the injection port 114 of the packaging container 110, preventing any arbitrary opening operation and making it possible to maintain a stable closed state.

[0030] Next, reference is made to Fig. 9. Fig. 9 shows a state in which the lid 120 has been rotated into an open state relative to the injection port 114. In this state, the second opening suppression rib 122 formed on the inner peripheral surface of the lid 120 is forcibly released from engagement with the first opening suppression rib 116 formed on the outer peripheral surface of the injection port 114, and the first locking piece 118 formed on the injection port 114 and the second locking piece 124 formed on the inner peripheral surface of the lid 120 are also forcibly released from their mutual engagement state.

[0031] Therefore, in the state shown in Figure 9, the lid 120 is in a state where the forced locking force on the injection port 114 of the packaging container 110 is completely released, making it possible to forcibly separate it from the injection port 114, and the open state of the lid subsequently provides a closed coupling position for the lid.

[0032] In addition, when the lid 120 is in an open state relative to the injection port 114 as shown in Figure 9, the second open-prevention rib 122 formed on the inner surface of the lid 120 has overcome the first open-prevention rib 116 formed on the outer surface of the injection port 114 to reach the open position, and is shifted by the open rotation angle so that the locking force is released.

[0033] As specifically described above, according to the rotating opening and closing structure of a lid for a packaging container having a non-circular type injection port of the present invention, the lid 120 can be rotated and opened / closed relative to the injection port 114 by simply rotating the second opening prevention rib 122 formed on the inner surface of the lid 120 to the extent that it is engaged or released in an alternating manner relative to the first opening prevention rib 116 formed on the outer peripheral surface of the injection port 114 of the packaging container 110, thereby enabling the lid 120 to be rotated and opened / closed relative to the injection port 114, and although the rotational opening and closing operation distance of the lid 120 is very short, quick and simple opening and closing operations are possible.

[0034] In addition, through the above-mentioned rotating opening and closing structure of the lid 120, even if the injection port 114 is formed in a non-circular type, including a polygonal shape, it is possible to provide a new advantage that induces a new feeling and curiosity by rotating and opening the lid 120 without any sense of rejection or inconvenience due to the rotating opening and closing operation of the lid 120, and through the above-mentioned rotating opening and closing method of the lid 120, it is possible to provide various designs of the lid 120 including the packaging container 110.

[0035] Meanwhile, according to the present invention, the cover 120 may further be formed with a drawer space 126 for drawing out and using the package contents.

[0036] Furthermore, according to the present invention, the cover 120 may further be formed with a storage space 127 for separately storing and using various tools for using the separate package contents according to the purpose.

[0037] Furthermore, according to the present invention, the inner peripheral surface of the lid 120 may further be provided with a packing 128 for providing high airtightness against the upper surface of the injection port 114 of the packaging container 110 .

[0038] According to the present invention, the cover 120 may further include an auxiliary cover 129 for airtightly closing or opening the drawer space 126, which can be opened and closed via a hinge 129a.

[0039] Although the present invention has been described with reference to the accompanying drawings, it will be understood that the invention is not limited thereto and that various modifications and changes can be made thereto without departing from the scope of the following claims.
