Description

[Technical Field]

[0001] The present invention relates to a rotary 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 rotary manner as if the lid were opened and closed on the outer 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 is circular, the lid is opened and closed by rotating it around the circular injection port using a method such as screwing, and when the injection port is non-circular, including polygonal injection ports, the lid is opened and closed mainly by an undercut method, which opens and closes the lid in the vertical direction around 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 types of lid appearance have been offered.

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

[0006] [Patent Document 1] Korean Utility Model Publication No. 20-1998-0060960 Summary of the Invention [Problem to be solved by the invention]

[0007] Therefore, the present invention has been made to solve the above-mentioned conventional problems, and its object is to provide a rotary opening and closing structure for a lid of a packaging container having a non-circular type injection port, which can be opened and closed quickly and easily using a rotary opening and closing method just like opening and closing a lid of a circular type injection port of a packaging container having a non-circular type, including a polygonal type. [Means for solving the problem]

[0008] In order to achieve the above-mentioned object, the rotating opening and closing structure of a lid for a packaging container having a non-circular type injection port of the present invention comprises: a packaging container having a packaging space in which the packaging contents are stored, an injection port formed at the open end of the packaging space, the injection port being of a non-circular type that includes a polygon; and a lid that is rotated open and closed relative to the injection port of the packaging container; and characterized in that one or more first opening-inhibiting ribs protrude vertically at an appropriate interval from the outer peripheral surface of the injection port, and one or more first locking pieces having an outer surface that narrows in the opening direction of the lid are arranged to protrude horizontally at an appropriate interval between the first opening-inhibiting ribs, and second opening-inhibiting ribs protrude vertically from the inner peripheral surface of the lid, which are engaged and released in an alternating manner relative to the first opening-inhibiting rib when the lid is rotated open and closed, and second locking pieces protrude horizontally between the second opening-inhibiting ribs, which are forcibly engaged and released relative to the first locking pieces, respectively.

[0009] According to the present invention, the lid may further have a drawer space formed therein for drawing out and using the contents of the package.

[0010] According to the present invention, the lid may further have a storage space formed therein for separately storing and using various tools for using the contents of the package depending on the purpose.

[0011] According to the present invention, a packing is further provided inside the inner peripheral surface of the lid to provide high airtightness to the upper surface of the injection port of the packaging container.

[0012] According to the present invention, the cover may further include an auxiliary cover that can be opened and closed via a hinge to airtightly close or open the drawer space. [Effects of the Invention]

[0013] According to the present invention, even if the injection port of a packaging container is formed into a non-circular type, including a polygonal type, the lid that opens and closes on the injection port can be easily opened and closed using a rotary opening and closing method, and the opening and closing operation can be performed in the same way as opening and closing the lid of an existing circular injection port.Even if the shape of the injection port is different, it is possible to quickly and easily open and close the lid without causing any sense of rejection or inconvenience when opening and closing it, and it is also possible to provide the effect of stimulating consumers' curiosity about the new opening and closing method.

[0014] Furthermore, even if the injection port of the packaging container is formed in a non-circular type, such as a polygonal type, the lid can be opened and closed using the rotational opening and closing method as in the past, making it possible to provide a variety of designs for the packaging container and lid.

DETAILED DESCRIPTION OF THE INVENTION

[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 polygonal, and a lid 120 that opens and closes the injection port of the packaging container in a rotating opening and closing manner.

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

[0019] The injection port 114 formed at the open end of the packaging space 112 is extended 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, as described above, when the shape of the injection port 114 of the packaging container 110 is a non-circular type, including a polygonal type, there are significant structural limitations to realizing the conventional method of rotating the lid to open and close it.

[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 rotational manner for a packaging container 110 having a non-circular injection port 114, including a polygonal one, as will be described later.

[0023] For this purpose, in the present invention, one or more first opening-preventing ribs 116 are provided at appropriate intervals to protrude vertically from the outer peripheral surface of the injection port 114 of the packaging container 110, which is of a non-circular type including the polygonal shape, and one or more first locking pieces 118 having an outer surface 119 that narrows in the opening direction of the lid are arranged between the first opening-preventing 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.Furthermore, 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 relative to 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, they are not limited to this terminology as long as they perform the same locking and unlocking functions, and their horizontal angle may be different, such as being formed to tilt in the closing direction of the lid.

[0026] In addition, the first opening prevention rib 116 and the second opening prevention rib 122 are configured to prevent any arbitrary opening operation of the lid 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 can be implemented in addition to the above rib shapes.

[0027] According to the rotational 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 rotational opening and closing in the same manner as a conventional circular type injection port. The rotational opening and closing structure of the lid 120 for the injection port 114 of the packaging container 110 will be described below.

[0028] First, let us refer to Figure 8. Figure 8 shows the state in which the lid 120 has been rotated to the closed position relative to the inlet 114. In this state, the second open-restraint rib 122 formed on the inner peripheral surface of the lid 120 is elastically engaged in a staggered manner with the first open-restraint rib 116 formed on the outer peripheral surface of the inlet 114. This maintains a stable locked state unless an external force is applied to a portion of the lid 120 to open it, thereby preventing or suppressing any unintended opening of the lid. The first locking piece 118 formed on the inlet 114 and the second locking piece 124 formed on the inner peripheral surface of the lid 120 are in an interlocked state.

[0029] Therefore, in the state shown in Figure 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 Figure 9. Figure 9 shows a state in which lid 120 has been rotated into an open state relative to inlet 114. In this state, second open-restraint rib 122 formed on the inner peripheral surface of lid 120 is forcibly released from engagement with first open-restraint rib 116 formed on the outer peripheral surface of inlet 114, and first locking piece 118 formed on inlet 114 and second locking piece 124 formed on the inner peripheral surface of 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 the open position, and is therefore 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 the 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 lid 120 to the extent that the second opening prevention rib 122 formed on the inner surface of the lid 120 is engaged or released in an alternating manner relative to the first opening prevention rib 116 formed on the outer surface of the injection port 114 of the packaging container 110, thereby enabling quick and easy opening and closing operations to be performed, even though the rotational opening and closing operation distance of the lid 120 is very short.

[0034] Furthermore, through the above-described rotational opening and closing structure of the lid 120, even if the injection port 114 is formed in a non-circular type, including a polygonal type, it is possible to provide a new advantage of inducing a novel feeling and curiosity by rotating and opening the lid 120 without causing any sense of rejection or inconvenience due to the rotational opening and closing operation of the lid 120, and through the above-described rotational opening and closing method of the lid 120, it is possible to provide various designs of the lid 120 as well as the packaging container 110.

[0035] Meanwhile, according to the present invention, the cover 120 may further be formed with a drawer space 126 for pulling 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 contents of the package depending on the purpose.

[0037] Furthermore, according to the present invention, the inner circumferential surface of the lid 120 may further be provided with a packing 128 for providing high airtightness to 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 appreciated 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.
