Abstract
Description
Technical Field
[0001] This invention discloses a rotating opening and closing structure for a lid of a packaging container with a non-circular type of injection port, which allows the lid to be easily opened or closed by rotation for packaging containers with non-circular type injection ports such as polygons, just as if it were opened and closed for a circular outer surface. Background Technology
[0002] Various packaging containers, including cosmetic containers, typically have a spout, and the way the cap (including the cover) opens and closes varies depending on the shape of the spout.
[0003] For example, if the injection port is circular, most caps are opened and closed by rotating in a screw-in manner. If the injection port is non-circular, including polygonal injection ports, the main method is to open and close the cap by an undercut method that opens or closes the cap in the vertical direction relative to the injection port.
[0004] Therefore, existing technologies make the injection port round for the sake of ease of opening and closing the lid, and do not provide a non-circular injection port. At most, the appearance of the lid is designed to be non-circular for the sake of the lid's aesthetics.
[0005] At the same time, consumers are also accustomed to opening and closing the lid in a rotating manner, such as by a threaded connection, because the injection port of the packaging container is formed in a circular shape.

[0010] Therefore, the present invention aims to solve the problems of the prior art as described above. The purpose of the present invention is to provide a rotating opening and closing structure for a lid of a packaging container with a non-circular type injection port, which allows the lid to be opened and closed quickly and easily in a rotating manner for a non-circular type injection port of a packaging container, such as a polygon, as if it were a circular injection port.
[0011] means of solving technical problems
[0012] To achieve the aforementioned objective, the present invention provides a rotating opening and closing structure for a packaging container with a non-circular injection port, comprising: a packaging container having a packaging space for containing packaged contents, an injection port being formed at an open end of the packaging space, the injection port being formed in a non-circular shape such as a polygon; and a lid for rotating opening and closing operations on the injection port of the packaging container; one or more first opening-resisting ribs protruding vertically at appropriate intervals on the outer peripheral surface of the injection port, and one or more first retaining tabs having an outer surface that narrows towards the opening direction of the lid being disposed between the first opening-resisting ribs and the first opening-resisting ribs being disposed horizontally at appropriate intervals; on the inner peripheral surface of the lid, second opening-resisting ribs that engage and disengage relative to the first opening-resisting ribs in an interleaved manner during the rotating opening and closing operation of the lid are formed vertically, and second retaining tabs that are forcibly engaged and disengaged relative to the first retaining tabs are formed horizontally between the second opening-resisting ribs and the first retaining tabs.
[0013] According to the present invention, the lid also forms an outlet space for drawing out and using the contents of the package.
[0014] According to the present invention, the lid also forms a storage space for storing and using various tools for using the contents of the package according to their intended purpose.
[0015] According to the present invention, the inner circumferential surface of the cap also has a sealing element, which is used to provide a high airtightness to the upper surface of the injection port of the packaging container.
[0016] According to the present invention, the cover is further provided with an auxiliary cover for airtightly locking or opening the outlet space, which can be opened and closed by a hinge.
[0017] Technical effect

[0029] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
[0030] Please see Figures 1 to 9 The present invention provides a rotating opening and closing structure for a lid of a packaging container having a non-circular type injection port, comprising: a packaging container 110 having a non-circular type injection port 114 such as a polygon; and a lid 120 for opening or closing the injection port of the packaging container in a rotating manner.
[0031] The packaging container 110 has an internal packaging space 112 that is open to one side for holding various packaging contents.
[0032] The injection port 114 formed at the open end of the packaging space 112 extends inward in a step-like manner.
[0033] Moreover, in addition to the quadrilateral shape shown in the figure, the injection port 114 can also be formed in various other polygonal or non-circular shapes.
[0034] According to the present invention, if the injection port 114 of the packaging container 110 is formed in a non-circular shape such as a polygon as described above, the structure is greatly restricted when the lid is implemented by a rotation opening and closing method as in the prior art.
[0035] Therefore, the technical feature of the present invention is that, for a packaging container 110 having a non-circular type injection port 114 such as a polygon, as described below, the lid 120 can be easily opened or closed by rotation.
[0036] Therefore, in this invention, on the outer peripheral surface of the injection port 114 of the packaging container 110 formed of a non-circular type such as a polygon, one or more first opening suppression ribs 116 are formed at appropriate intervals in a vertical direction, and one or more first retaining tabs 118 are each formed at appropriate intervals in a horizontal direction on the outer side surface 119 having a shape that narrows in the direction in which the lid is opened between the first opening suppression ribs 116 and the first opening suppression ribs 116.
[0037] Furthermore, on the inner circumferential surface of the lid 120, which is open in one direction, a second opening suppression rib 122 is formed in a vertical direction to intercept and release the first opening suppression rib 116 formed on the injection port 114 of the packaging container 110 during the opening and closing operation of the lid. Moreover, a second blocking piece 124 is formed in a horizontal direction to forcibly intercept and release the first blocking piece 118 between the second opening suppression rib 122 and the first blocking piece 118.
[0038] On the other hand, although the first latching piece 118 and the second latching piece 124, which are respectively formed on the outer peripheral surface of the injection port 114 and the inner peripheral surface of the cover 120, are formed in a horizontal direction to maintain their stable latching and release operation when the cover is opened and closed, they can be formed at various horizontal angles without being limited by their terminology, as long as they perform the same latching and release functions. For example, they can be formed in a shape that is inclined towards the closing direction of the cover.
[0039] Furthermore, the first opening suppression rib 116 and the second opening suppression rib 122 are components that prevent the lid from opening unauthorizedly after the lid 120 of the injection port 114 of the packaging container 110 has been closed. However, as long as their function can be achieved, various modifications other than the rib shape can be adopted, such as a blocking protrusion or a blocking groove, as long as they can achieve their function.
[0040] According to the present invention configured as described above, the lid rotation opening and closing structure for a packaging container having a non-circular injection port allows the lid 120 to be opened or closed in a rotational manner, just like a conventional circular injection port, even if the injection port 114 of the packaging container 110 is formed in a non-circular shape such as a polygon. The rotation opening and closing structure for the lid 120 of the injection port 114 of the packaging container 110 will be described below.
[0041] First, please refer to Figure 8 . Figure 8 The cap 120 is rotated to the closed position relative to the inlet 114. In this state, the first opening inhibition rib 116 formed on the outer peripheral surface of the inlet 114 and the second opening inhibition rib 122 formed on the inner peripheral surface of the cap 120 are elastically locked in an alternating manner. Therefore, unless an external force is intentionally applied to open the cap 120, it will maintain a stable locked state, thus preventing or inhibiting the cap from opening on its own. Furthermore, the first locking piece 118 formed on the inlet 114 and the second locking piece 124 formed on the inner peripheral surface of the cap 120 are locked in a mutually locking state.
[0042] Therefore, in such Figure 8 In the state shown, the lid 120 is forcibly closed at the injection port 114 of the packaging container 110, thus preventing unauthorized opening and maintaining a stable closed state.
[0043] Next, please refer to Figure 9 . Figure 9 The cap 120 is in the open state when rotated relative to the inlet 114. In this state, the second opening inhibition rib 122 formed on the inner circumferential surface of the cap 120 is forcibly released from its blocking position against the first opening inhibition rib 116 formed on the outer circumferential surface of the inlet 114, and the first blocking piece 118 formed on the inlet 114 and the second blocking piece 124 formed on the inner circumferential surface of the cap 120 are also forcibly released from their mutual blocking position.
[0044] Therefore, in Figure 9 In the indicated state, the lid 120 is in a state where the forced blocking force against the injection port 114 of the packaging container 110 is completely released, allowing it to be forcibly separated from the injection port 114. Moreover, the open state of the lid provides a position for the lid to be closed and engaged later.
[0045] At the same time, such as Figure 9If the cover 120 is in the open state relative to the inlet 114, the second opening inhibition rib 122 formed on the inner circumferential surface of the cover 120 moves to the open position along the first opening inhibition rib 116 formed on the outer circumferential surface of the inlet 114, and thus becomes a state of being offset by the following rotation angle, which is the angle at which it is opened to release its blocking force.
[0046] As specifically described above, according to the present invention, the lid rotation opening and closing structure for a packaging container with a non-circular injection port, the second opening inhibition rib 122 formed on the inner circumferential surface of the lid 120 can easily perform a rotation operation on the lid 120 for the injection port 114 by interlocking or releasing the first opening inhibition rib 116 formed on the outer circumferential surface of the injection port 114 of the packaging container 110. This enables the lid 120 to rotate and close the injection port 114 in a very short distance and allows for quick and easy opening and closing operations.
[0047] Moreover, thanks to the rotating opening and closing structure of the lid 120 as described above, even if the injection port 114 is formed in a non-circular type such as a polygon, the rotating opening and closing operation of the lid 120 is not rejected at all and will not feel inconvenient. On the contrary, the rotating opening and closing of the lid 120 can bring a new feeling or arouse curiosity, thus providing an advantage. The rotating opening and closing method of the lid 120 as described above can provide a variety of appearance designs for the packaging container 110 and the lid 120.
[0048] On the other hand, according to the present invention, the lid 120 may also be formed with an outlet space 126 for outleting and using the contents of the package.
[0049] Furthermore, according to the present invention, the lid 120 may also form a storage space 127, which separately stores and uses various additional tools for using the contents of the package according to their intended purpose.
[0050] Furthermore, according to the present invention, the inner peripheral surface of the lid 120 may also have a seal 128, which is used to provide a high airtightness against the upper surface of the injection port 114 of the packaging container 110.
[0051] Furthermore, according to the present invention, the cover 120 is also provided with an auxiliary cover 129 for airtightly locking or opening the outlet space 126, which can be opened and closed by means of the hinge 129A.
[0052] Although the invention has been described above in conjunction with the accompanying drawings, it is not limited thereto, and many modifications and variations can be made without departing from the scope of the following claims.
