[0047] Hereinafter, a container cap and a container incorporating the same according to the present invention will be described with reference to the accompanying drawings.

[0048] like Figures 1 to 2 As shown, the container cover of the first embodiment of the present invention is a container cover 100 that is combined with the container inlet 12 of the container 10 for storing contents, including: a cover body 110, which is combined with the container inlet 12 and forms an auxiliary space S1 on the upper side to store the auxiliary contents 42 with a granular structure; an upper cover 120, which is combined with the cover body 110, forms the auxiliary space S1 together with the cover body 110 and covers the auxiliary space S1.

[0049] The container 10 is a structure for storing liquid substances such as beverages, powdered substances, etc., and can be of any structure as long as a container inlet 12 for discharging the container is formed.

[0050] The contents stored in the container 10 may be various substances depending on the combination with the auxiliary contents. For example, a liquid substance to be taken together with the auxiliary contents 42 described later and a solid pill may be a normal liquid substance.

[0051] In addition, the portion of the container 10 excluding the container inlet 12 may have various shapes, such as a cylindrical shape, a quadrangular column shape.

[0052] The container 10 may be made of plastic, glass or other materials.

[0053] On the other hand, the container inlet 12 serves as a discharge port for discharging the contents to the outside and is opened and closed by the container cover 100 . The container inlet 12 may have various structures depending on its connection structure.

[0054] The cover body 110 is coupled to the container inlet 12 and forms an auxiliary space S1 on the upper side for storing the auxiliary contents 42 having a granular structure. The cover body 110 may have various structures depending on the coupling structure with the container inlet 12 and the coupling structure with the upper cover 120 .

[0055] The cover body 110 may be coupled to the container inlet 12 through various structures such as screw coupling or snap coupling.

[0056] In particular, the cover body 110 can seal the interior of the container 10 when combined with the container inlet 12. Preferably, a sealing component (not shown) is provided, but a sealing component is not required, and it can have a combination structure disclosed in International Publication No. WO2021 / 017348.

[0057] Then, the cover body 110 may include a container combining portion 111 combined with the container inlet 12 , and a cover combining portion 112 extending upward from the container combining portion 111 and combined with the upper cover 120 .

[0058] The container coupling portion 111 is a portion coupled to the container inlet 12 and may have various structures depending on the coupling structure with the container inlet 12 .

[0059] That is, the container coupling portion 111 may be coupled to the container inlet 12 via various coupling structures such as threaded coupling or snap coupling.

[0060] In particular, the container coupling portion 111 can seal the interior of the container 10 when coupled to the container inlet 12. Preferably, a sealing component (not shown) is interposed, but a sealing component is not required, and the coupling structure disclosed in International Publication No. WO2021 / 017348 can be provided.

[0061] In addition, if Figure 1 and Figure 2 As shown, in order to confirm whether the container is initially opened when the container coupling portion 111 is coupled to the container inlet 12 , the skirt portion 130 may be connected by a plurality of bridges 131 and engaged with the engaging protrusions 15 formed on the outer circumference of the container inlet 12 .

[0062] In addition, the container coupling portion 111 may form a female thread portion 111 a . When the container coupling portion 111 is threadedly coupled to the container inlet 12 , the female thread portion 111 a is threadedly coupled to the male thread portion 12 a formed at the container inlet 12 .

[0063] The cover coupling portion 112 is a portion extending upward from the container coupling portion 111 to couple with the upper cover 120 . The cover coupling portion 112 may have various structures depending on the coupling structure with the upper cover 120 , and will be described together with the upper cover 120 .

[0064] On the other hand, in order to form the auxiliary space S1 , the container coupling portion 111 and the lid coupling portion 112 are preferably partitioned into upper and lower parts by a partition portion 140 coupled to the inner peripheral surface.

[0065] The partition wall 140 is coupled to the inner circumference of the lid body 110 to vertically partition the container coupling portion 111 and the lid coupling portion 112 to form the auxiliary space S1 , and may have various structures depending on the vertical partitioning structure.

[0066] As an example, Figure 1 and Figure 2 As shown, the partition wall 140 has a disc shape and is formed integrally with the cover body 110 , or is fitted into a groove or protrusion 117 formed on the inner circumference of the cover body 110 .

[0067] On the other hand, in addition to the disc shape, the partition wall portion 140 may have various shapes and structures according to the embodiments described below in order to strengthen the structure and function of coupling with the container inlet 12 .

[0068] The upper cover 120 is coupled to the cover body 110 to form the auxiliary space S1 together with the cover body 110 and to cover the auxiliary space S1 . The upper cover 120 may have various structures depending on the coupling structure with the cover coupling portion 112 .

[0069] Here, if Figures 1 to 8As shown, the upper cover 120 is connected to the cover coupling portion 112 through a hinge portion 150 at one end of a reference line passing through the center of the upper cover 120 , and can be rotated based on the hinge portion 150 to be detachable from the cover coupling portion 112 .

[0070] The upper cover 120 may include an upper surface portion 121 parallel to a partition wall portion 140 described later and constituting an upper surface of the container cover; and a side wall portion 122 extending downward from an edge of the upper surface portion 121 .

[0071] The upper surface portion 121 , which is parallel to the partition wall portion 140 and constitutes the upper surface of the container lid, may have a disc shape.

[0072] In addition, the overall shape of the upper portion 121 may be changed, such as forming a slightly concave center portion according to design, storage conditions, etc., to impart functionality to the upper portion 121 .

[0073] The side wall portion 122 is an extension portion of the outer peripheral surface of the cover body 110 (described later) extending from the upper surface portion 121 and can be variously deformed according to design, storage conditions, etc.

[0074] The hinge portion 150 is a structure that connects the cover coupling portion 112 and the upper cover 120 at one end of a reference line passing through the center of the upper cover 120. As long as the connection is such that the upper cover 120 can hinge and rotate relative to the cover coupling portion 112, various connection methods can be used.

[0075] In particular, the hinge portion 150 allows the upper cover 120 to be hinged relative to the cover coupling portion 112 , and the thickness and width of the hinge portion 150 can be set to maintain a certain degree of unsealing.

[0076] In addition, if Figures 1 to 4 As shown, when the upper cover 120 is combined with the hinge part 150, a separate sealing tool is configured to combine the lower end of the upper cover 120 and the upper end of the cover combining part 112 at intervals to achieve smooth hinge rotation.

[0077] On the other hand, it is preferred that a handle portion 160 is formed at a portion facing the hinge portion 150 to facilitate separation of the upper cover 120 from the cover coupling portion 112 by the user when the upper cover 120 is coupled to the hinge portion 150 and coupled to the upper cover 120.

[0078] The handle portion 160 is formed at a portion facing the hinge portion 150 to facilitate separation of the upper cover 120 from the cover coupling portion 112 by a user, and may have various structures.

[0079] As an example, the handle portion 160 may have a structure similar to the separation portion disclosed in International Publication No. WO2021 / 017348.

[0080] In addition, the handle portion 160 may be integrally extended from a portion facing the hinge portion 150 and the upper cover 120 toward the outside of the cover coupling portion 112 .

[0081] In addition, if Figure 2 As shown, when the user separates the upper cover 120 from the cover coupling portion 112 , the handle portion 160 is bent upward, and the handle portion 160 can be kept fixed to the outer peripheral surface of the upper cover 120 .

[0082] Here, a coupling portion 161 may be formed on the outer circumferential surface of the upper cover 120 for coupling with the handle portion 160 .

[0083] The coupling portion 161 is formed on the outer peripheral surface of the upper cover 120 to couple with the handle portion 160 , and may have various structures depending on a coupling structure such as fitting.

[0084] On the other hand, in order to confirm whether the package is opened, the handle portion 160 may be kept coupled to the cover coupling portion 112 by adhesive or the like after being coupled to the cover coupling portion 112 .

[0085] Taking into account the possibility of injection molding, during manufacturing, the handle portion 160 can be manufactured in a state connected to the cover coupling portion 112, so that whether it is opened can be confirmed by a bridge or the like.

[0086] In addition, when the upper cover 120 is coupled to the cover body 110 , the handle portion 160 may remain coupled to a separate coupling portion (not shown) formed on the outer circumference of the cover coupling portion 112 .

[0087] The connection between the handle portion 160 and the connection portion may have various connection structures such as interlocking.

[0088] In the case of the structure in which the upper cover 120 is coupled to the cover coupling portion 112 via the hinge portion 150 , the upper cover 120 and the cover body 110 can be integrated by plastic injection molding, thereby facilitating manufacturing.

[0089] Furthermore, during use, since the upper cover 120 and the cover body 110 are formed into one piece, it is convenient to use. Furthermore, it also has the advantage of providing convenience during reuse, which has a great advantage in the industry.

[0090] like Figure 8 As shown, the upper cover 120 may be coupled to the cover coupling portion 112 by snap coupling or may be coupled to the cover coupling portion 112 by screw coupling.

[0091] On the other hand, the present invention is characterized in that the auxiliary space S1 is formed by the connection of the upper cover 120 and the cover connection portion 112 and the partition wall portion.

[0092] Here, the auxiliary space S1 is a space for storing auxiliary contents separately from the contents stored in the container 10 , and can store the auxiliary contents in combination with the contents.

[0093] In particular, the auxiliary contents stored in the auxiliary space S1 are in a state of being separated from the liquid contents stored inside the container 10 before taking, and are then taken together with the contents when taking. Compared with liquid substances, auxiliary contents with powder or granular structures (tablets, etc.) can be auxiliary contents.

[0094] On the other hand, considering that the auxiliary contents 41 are stored separately, it is preferable that the auxiliary space S1 is isolated from the outside air.

[0095] Accordingly, preferably, the upper cover 120 and the cover coupling portion 112 have a sealing tool for sealing the auxiliary space S1 when the upper cover 120 and the cover coupling portion 112 are coupled to each other.

[0096] The sealing tool serves as a structure for sealing the auxiliary space S1 when the upper cover 120 and the cover coupling portion 112 are coupled to each other. According to the coupling structure of the upper cover 120 and the cover coupling portion 112, in particular, the above-mentioned coupling structure, that is, multiple embodiments (embodiments 1 to 6), can have various structures.

[0097] As an example, Figure 1 and Figure 2 As shown, the sealing tool may include a cover inner ring 123 . When the upper cover 120 is combined with the cover coupling portion 112 , the cover inner ring 123 is in close contact with the inner circumference of the cover coupling portion 112 .

[0098] The cover inner ring 123 is formed inside the side wall portion 122 of the upper cover 120 and is in close contact with the inner circumference of the cover coupling portion 112 when the upper cover 120 is coupled to the cover coupling portion 112 .

[0099] As an example, the cover inner ring 123 may be formed to protrude downward from the bottom surface of the upper cover 120 .

[0100] In addition, considering that the cover inner ring 123 is in close contact with the inner peripheral surface of the cover coupling portion 112 , the cover inner ring 123 has a thickness that allows elastic deformation and is preferably formed to be thinner toward the lower side.

[0101] Furthermore, considering that the cover inner ring 123 is inserted into the inner peripheral surface of the cover coupling portion 112 , the cover inner ring 123 is preferably formed so that the outer peripheral surface thereof is inclined 123 a toward the center as it moves toward the lower side.

[0102] In addition, in order to strengthen the sealing state when the cover inner ring 123 is tightly attached to the inner circumference of the cover joint 112, as shown in FIG. Figure 1 and Figure 2 As shown, the sealing tool may further include one or more annular protrusions 118 , which protrude from the inner circumference of the cover coupling portion 112 and may be closely attached to the outer circumference of the cover inner ring 123 .

[0103] The annular protrusion 118 is one or more annular structures that protrude from the inner circumference of the cover joint 112 and can be tightly attached to the outer circumference of the cover inner ring 123 . It can be formed as a protruding structure bulging from the inner circumference of the cover joint 112 .

[0104] The container lid of the present invention having the structure as described above is combined with the container inlet 12 of the container 10 for storing liquid contents, and stores auxiliary contents 41 that can be taken together with the liquid contents in the auxiliary space S1, thereby having the advantage of maximizing the function of the container.

[0105] In particular, the existing container lid has multiple parts when forming a structure for storing auxiliary contents, and requires deforming the container inlet 12, so the structure is complex and the manufacturing cost is high. However, the present invention is formed by an integrated structure or even a simple structure, so it is simple to manufacture, and in particular, it has the advantage of providing convenience through a single structure when recycling for reuse.

[0106] On the other hand, the basic point of the present invention is to propose a simple structure of a container lid having an auxiliary space for storing auxiliary contents, and various embodiments can be realized according to the combination structure with the lid body 110 and the upper cover 120.

[0107] Hereinafter, a modified embodiment of the first embodiment of the present invention will be described with a focus on the parts that are different from the first embodiment. For the sake of convenience, the same or similar parts as those of the first embodiment of the present invention will be omitted.

[0108] The container cap of the second embodiment of the present invention is an embodiment in which an auxiliary container 30 for storing a second auxiliary content is further provided in addition to the structure of the first embodiment of the present invention.

[0109] Hereinafter, a container cap according to a second embodiment of the present invention will be described, focusing on the parts that differ from the first embodiment.

[0110] The auxiliary container 30 is a container coupled to the cover body 110 to store second auxiliary contents that are the same as or separate from the auxiliary contents in the auxiliary space S1 , and may have various structures depending on the coupling structure with the cover body 110 .

[0111] As an example, the auxiliary container 30 may include: an upper side portion 31, which is combined with the container combining portion 111 by being engaged with the inner circumferential surface of the container combining portion 111; a side wall portion 32, which extends toward the lower side of the upper side portion 31 to form a second auxiliary space S2; and a covering portion 33, which is detachably combined at the lower end of the side wall portion 32 to cover the second auxiliary space S2.

[0112] The upper portion 31 is a structure that is engaged with the inner peripheral surface of the container coupling portion 111 to be coupled to the container coupling portion 111 , and may have various structures.

[0113] As an example, the upper portion 31 may have a disc structure that is in close contact with the bottom surface of the partition wall 140 .

[0114] Then, the edge of the upper portion 31 is inserted between the bottom surface of the partition portion 140 and the upper end of the container inlet 12 , thereby functioning as a sealing member for sealing the inner space S3 of the container 10 .

[0115] The side wall portion 32 is a structure extending toward the lower side of the upper portion 31 to form the second auxiliary space S2 , and may have various structures.

[0116] As an example, the side wall portion 32 extends toward the lower side of the upper portion 31 , and the second auxiliary space S2 may be formed into a cylindrical space.

[0117] The cover portion 33 is detachably coupled to the lower end of the side wall portion 32 to cover the second auxiliary space S2 . To prevent mixing with the contents inside the container 10 , the cover portion 33 is preferably sealed.

[0118] like Figure 3 and Figure 4 As shown, one end of the covering portion 33 is hingedly connected to the side wall portion 32, and the other end can be engaged with the protrusion 33a and the groove portion 32a.

[0119] In addition, the cover portion 33 is integrally formed with the upper portion 31 and the side wall portion 32 by plastic injection molding or can be composed of a sealing member that seals the lower end of the side wall portion 32 by electromagnetic, conductive, or the like.

[0120] On the other hand, an example is given in which the upper side portion 31 of the auxiliary container 30 is formed separately from the partition wall portion 140, but the cover body 110 is formed through from top to bottom, and the upper side portion 31 of the auxiliary container 30 is detachably arranged on the inner peripheral surface of the cover body 110, which can of course also be constructed as the partition wall portion 140.

[0121] Specifically, in Figure 3 In the embodiment, this can be achieved by forming the upper portion 31 of the auxiliary container 30 and the partition wall portion 140 into one piece, and detachably disposing the upper portion 31 of the auxiliary container 30 on the inner circumferential surface of the cover body 110 .

[0122] That is, in Figure 3 This may be realized as an example of a portion in which the edge of the upper side portion 31 of the auxiliary container 30 is removed in the partition wall portion 140 .

[0123] The container lid of the second embodiment having the structure as described above is additionally configured with an auxiliary container 30 forming a second auxiliary space S2 on the basis of the auxiliary space S1 formed on the upper side of the partition portion 140, and further, when the contents stored in the container 10 are taken, the second auxiliary content is added on the basis of the auxiliary content, thereby being given various functions.

[0124] On the other hand, as described above, considering that the auxiliary contents are stored in the auxiliary space S1 , it is necessary to seal the auxiliary space S1 to prevent the entry of external air.

[0125] Hereinafter, a third embodiment will be described, which includes a sealing tool that seals the auxiliary space S1 separately from or together with the sealing tool disclosed in the first embodiment of the present invention.

[0126] like Figures 5 to 7 As shown, the container cap according to the third embodiment of the present invention is characterized in that it has a sealing tool for sealing the auxiliary space S1 separately from or together with the sealing tool disclosed in the first embodiment of the present invention.

[0127] The sealing tool may include: one or more first concave-convex parts 811 formed at the upper end of the cover coupling part 112; and a second concave-convex part 821 formed at the lower end of the upper cover 120 to match and fit tightly with the first concave-convex part 811 when the upper cover 120 is coupled to the cover coupling part 112.

[0128] The sealing tool disclosed in the second embodiment of the present invention is configured at the lower end of the upper cover 120 and the upper end of the cover coupling portion 112 to seal the auxiliary space S1 , and is characterized by having a concave-convex structure.

[0129] The first concavo-convex portion 811 is one or more concavo-convex portions formed on the upper end of the cover coupling portion 112 and may have various structures depending on the shape of the second concavo-convex portion 821 described later.

[0130] As an example, the first concave-convex portion 811 may be composed of a pair of protrusions forming a groove to be inserted into the protrusion of the second concave-convex portion 821 described later.

[0131] Here, the first concave-convex portion 811 is merely a convex portion when viewed from a cross-sectional structure, but is of course in a ring shape when viewed from the top.

[0132] The second concave-convex portion 821 is formed at the lower end of the upper cover 120 to closely match the first concave-convex portion 811 when the upper cover 120 is coupled to the cover coupling portion 112 , and may have various structures.

[0133] As an example, the second concave-convex portion 821 may be formed by a protrusion inserted into a groove formed by a pair of protrusions of the first concave-convex portion 811 .

[0134] On the other hand, as described above, considering that the auxiliary contents are stored in the auxiliary space S1 , it is necessary to seal the auxiliary space S1 to prevent the entry of external air.

[0135] Hereinafter, a fourth embodiment will be described, which includes a sealing tool that seals the auxiliary space S1 separately from or together with the sealing tool disclosed in the first embodiment of the present invention.

[0136] Compared with the first embodiment, the container cover of the fourth embodiment has deformations in the snap-fitting structure between the upper cover and the cover coupling portion, and the coupling structure between the container coupling portion and the container inlet.

[0137] First, if Figure 8 As shown, the upper cover 120 is a separate component instead of being formed integrally with the cover coupling portion 112, and can be coupled to the cover coupling portion 112 by snap coupling.

[0138] To this end, an annular protrusion 831 is formed on any one of the upper cover 120 and the cover coupling portion 112 , and the remaining one may be formed into an annular groove 841 .

[0139] Then, if Figure 9 and Figure 10 As shown, in order to confirm whether the upper cover 120 is initially separated from the cover coupling portion 112 , the upper cover 120 may be formed with an auxiliary skirt 851 connected by a plurality of auxiliary bridges 862 .

[0140] like Figure 9 As shown, the auxiliary skirt 851 is stuck in the annular protrusion 861 formed on the outer peripheral surface of the coupling portion 112 , and can be separated from the upper cover 120 by disconnecting the auxiliary bridge 862 when the upper cover 120 is separated from the cover coupling portion 112 .

[0141] Then, as a sealing tool for sealing the auxiliary space S1, a sealing tool can be disposed at the lower end of the upper cover 120 and the upper end of the cover coupling portion 112. The structure is similar to that of the third embodiment, so detailed description is omitted.

[0142] Then, a container sealing tool may be further configured to seal the interior of the container 10 when the container coupling portion 111 and the container inlet 12 are coupled.

[0143] The container sealing tool may have various structures according to the container sealing structure.

[0144] As an example, Figure 10 As shown, the container sealing tool may include a cap inner ring 142 . When the cap body 110 is combined with the container inlet 12 , the cap inner ring 142 is in close contact with the inner circumference of the container inlet 12 .

[0145] The cover inner ring 142 is a structure that is in close contact with the inner circumference of the container inlet 12 when the container coupling portion 111 is coupled to the container inlet 12 , and may have various structures.

[0146] As an example, the cover inner ring 142 may be formed to protrude downward from the bottom surface of the partition wall portion 140 .

[0147] Furthermore, considering that the cover inner ring 123 is in close contact with the inner peripheral surface of the container inlet 12 , the cover inner ring 142 has a thickness that allows elastic deformation and is preferably formed to be thinner toward the lower side.

[0148] Furthermore, considering that the cap inner ring 142 is inserted into the inner peripheral surface of the container inlet 12 , the cap inner ring 142 is preferably formed so that the outer peripheral surface thereof is inclined 143 toward the center as it moves downward.

[0149] In addition, in order to strengthen the sealing state when the inner ring 142 of the cover is tightly attached to the inner circumference of the container inlet 12, it may also include one or more annular protrusions 12b, which protrude from the inner circumference of the container inlet 12 and can be tightly attached to the outer circumference of the inner ring 142 of the cover.

[0150] The annular protrusion 12 b is one or more protruding annular structures protruding from the inner circumference of the container inlet 12 and capable of closely contacting the outer circumference of the cover inner ring 142 , and can be formed as a protruding structure bulging from the inner circumference of the container inlet 12 .

[0151] On the other hand, as described above, a structure for sealing the container 10 may be configured between the upper end of the container inlet 12 and the bottom surface of the partition portion 140, such as the structure disclosed in International Publication No. WO2021 / 017348.

[0152] As an example, one or more first concave-convex portions 871 are formed at the upper end of the container inlet 12 , and a second concave-convex portion 872 may be formed on the bottom surface of the partition portion 140 so as to fit tightly with the first concave-convex portion 871 when the container inlet 12 is combined with the container combining portion 111 .

[0153] The first concavo-convex portion 871 is one or more concavo-convex portions formed on the upper end of the container inlet 12 and may have various structures depending on the shape of the second concavo-convex portion 872 described later.

[0154] As an example, the first concave-convex portion 871 may be composed of a pair of protrusions forming a groove to be inserted into the protrusion of the second concave-convex portion 872 described later.

[0155] Here, the first concave-convex portion 871 is merely a protrusion when viewed from a cross-sectional structure, but is of course in a ring shape when viewed from the top.

[0156] The second concave-convex portion 872 is formed at the lower end of the partition wall 140 to fit tightly with the first concave-convex portion 871 when the container coupling portion 111 is coupled to the container inlet 12 , and may have various structures.

[0157] As an example, the second concave-convex portion 872 may be formed by a protrusion inserted into a groove formed by a pair of protrusions of the first concave-convex portion 871 .

[0158] On the other hand, in the case of the second and third embodiments of the present invention, when the auxiliary container 30 is provided, Figure 11 As shown in FIG. 5 , as a fifth embodiment, the second concave-convex portion 872 may also be formed on the bottom surface of the upper portion 31 of the auxiliary container 30 instead of the partition wall 140 .

[0159] On the other hand, as Figures 1 to 11 In the variations of the illustrated embodiment 1 and embodiment 4, the partition wall 140 may be formed with one or more discharge ports 148 for discharging the contents stored in the container 10 .

[0160] Hereinafter, a container cap according to a fifth embodiment of the present invention will be described with reference to the accompanying drawings.

[0161] The container cap of the fifth embodiment of the present invention is a modification of the first and fourth embodiments, and is characterized in that one or more discharge ports 148 are formed in the partition wall 140 . The discharge ports 148 may have various structures depending on their formation structure and sealing structure.

[0162] like Figures 12 to 14 As shown, as an example, the container lid according to the fifth embodiment of the present invention may be formed with one or more discharge ports 148 , which are formed in the partition portion 140 to discharge the contents stored in the container 10 .

[0163] The discharge port 148 is a structure formed at least one in the partition wall 140 to discharge the contents stored in the container 10 , and may have various structures.

[0164] As an example of forming the discharge port 148, Figures 12 to 14 As shown, it is formed in the center portion of the partition wall 140, or as shown in FIG. Figure 15 As shown, the auxiliary space S1 is provided at the center, and the discharge port 148 may be formed at a part or the entire periphery of the auxiliary space S1 .

[0165] When the auxiliary space S1 is provided at the center and the discharge port 148 is formed on the entire periphery of the auxiliary space S1 , the partition wall portion 140 may be coupled to the inner peripheral surface of the cover body 140 via a plurality of bridges 146 .

[0166] On the other hand, the discharge port 148 may be formed by an upper protrusion 149 extending from the edge of the discharge port 148 formed through the upper and lower sides toward the upper side of the partition wall 140 .

[0167] In addition, as an example of forming the discharge port 148, Figure 16 As shown, a plurality of discharge ports 148 may be formed.

[0168] In addition, as an example of forming the discharge port 148, Figure 22a and Figure 22b As shown, when the cover body 110 is viewed from the upper side, the discharge port 148 is inclined to one side, especially the portion where the handle portion 160 is located, and the remaining portion may form the partition wall portion 140 .

[0169] On the other hand, the discharge port 148 can be isolated from the auxiliary space S1 and the internal space S3 of the container 10 by the isolation portion 128 disposed on the upper cover 120 .

[0170] The insulating portion 128 is disposed on the upper cover 120 to isolate the auxiliary space S1 and the internal space S3 of the container 10 when the upper cover 120 is coupled to the cover body 110 , and may have various structures depending on the isolation method.

[0171] As an example, the insulating portion 128 may have a structure similar to the aforementioned cover inner ring 123 .

[0172] Specifically, the insulating portion 128 is a structure that is in close contact with the inner peripheral surface of the upper protruding portion 149 when the upper cover 120 and the cover coupling portion 112 are in close contact with each other, and may have various structures.

[0173] As an example, the insulating portion 128 may be formed to protrude downward from the bottom surface of the upper cover 120 .

[0174] Furthermore, considering that the insulating portion 128 is in close contact with the inner peripheral surface of the upper protruding portion 149 , the insulating portion 128 has a thickness that allows elastic deformation and is preferably formed to be thinner toward the lower side.

[0175] Furthermore, considering that the insulating portion 128 is inserted into the inner peripheral surface of the upper protruding portion 149 , the insulating portion 128 is preferably formed so as to be inclined toward the center as the outer peripheral surface thereof goes downward.

[0176] In addition, in order to strengthen the sealing state when the isolation part 128 is tightly attached to the inner circumference of the upper protrusion 149, it may also include one or more annular protrusions 147, which protrude from the inner circumference of the upper protrusion 149 and can be tightly attached to the outer circumference of the isolation part 128.

[0177] The annular protrusion 147 is a protruding annular structure that protrudes from the inner circumference of the upper protrusion 149 and can be closely attached to the outer circumference of the isolation portion 128 . It can be formed as a protruding structure that bulges on the inner circumference of the upper protrusion 149 .

[0178] On the other hand, Figure 19 and Figure 20 As shown, the insulating structure using the exhaust port 148 of the insulating portion 128 may have various embodiments.

[0179] As an example, as a structure for preventing contents from entering between the lower end of the isolation portion 128 and the upper end of the upper protrusion 149, an annular protrusion 891 and an annular groove portion 892 inserted into the annular protrusion 891 may be formed at the lower end of the isolation portion 128 and the upper end of the upper protrusion 149.

[0180] At this time, if Figure 20 As shown, a ring-shaped protrusion 891 is formed, or as shown Figure 19 As shown, more than two annular protrusions 891 may be formed.

[0181] Then, the annular groove portion 892 can be configured into a tapered shape with a width that becomes narrower toward the inner side, so as to improve the close contact state when the annular protrusion portion 891 is inserted.

[0182] On the other hand, as described above, a structure for sealing the container 10 may be configured between the upper end of the container inlet 12 and the bottom surface of the partition portion 140, such as the structure disclosed in International Publication No. WO2021 / 017348.

[0183] like Figure 17 As shown, the upper end of the container inlet 12 and the bottom surface of the partition wall 140 may have a structure similar to the first concave-convex portion 871 and the second concave-convex portion 872, such as the fourth embodiment (see Figure 10 ).

[0184] In addition, the sealing connection between the upper cover 120 and the cover joint 112 can be achieved by using the sealing tool described in the first to fifth embodiments (see Figure 9 ) is implemented, as an example, it can have the same Figure 9 The example shown has a similar structure.

[0185] On the other hand, the container cap of the present invention may further include an anti-separation tool to prevent the upper cap 120 from being separated from the cap body 110 at will.

[0186] The separation prevention tool, which is a structure for preventing the upper cover 120 from being separated from the cover body 110 , may have various structures.

[0187] As an example, Figure 21a and Figure 21b As shown, the anti-separation tool may include: a moving part 480, which is inserted into a first groove 483 formed on the outer peripheral surface of the cover joint 112; and a guide part 482, which guides the moving part 480 from the first groove 483 to the second groove 124 formed on the outer peripheral surface of the upper cover 120 by using personnel.

[0188] The moving component 480 is inserted into the first groove 483 formed on the outer peripheral surface of the cover coupling portion 112 to prevent the upper cover 120 from being arbitrarily separated from the cover body 110, and then moved toward the second groove 124 by the user to separate the upper cover 120 from the cover body 110, and can have various structures.

[0189] At this time, the moving component 480 is formed with a narrow groove 481, and the narrow groove 481 is formed up and down so that the guide part 482 of the protruding structure can be inserted and the guide part 482 can be moved up and down.

[0190] The narrow groove 481 is formed in the movable part 480 so that the guide part 482 of the protruding structure can be inserted and the guide part 482 can be moved up and down. The upper and lower ends have the same size as the outer diameter of the guide part 482, and the middle part can be slightly smaller than the outer diameter of the guide part 482.

[0191] On the other hand, the guide portion 482 serves as a structure for guiding the movable component 480 to move from the first groove 483 to the second groove 124 formed on the outer peripheral surface of the upper cover 120 by the user, and can be composed of one or more protrusions protruding outward to be inserted into the narrow groove 481 formed in the movable component 480, and preferably can be composed of a pair of protrusions.

[0192] On the other hand, the container incorporating the container cover of the present invention having the structure as described above can be taken in various ways.

[0193] For example, the user separates the upper cover 120 from the cover body 110, i.e., the cover coupling portion 111, and then first takes the auxiliary contents 42 stored in the auxiliary space S1, and then separates the cover body 110 from the container 10 to take the contents stored in the container 10.

[0194] In addition, the user separates the cover body 110 from the container 10 to take the contents stored in the container 10, then combines the cover body 110 with the container 10, then separates the upper cover 120 from the cover body 110, that is, the cover coupling portion 111, and then takes the auxiliary contents 42 stored in the auxiliary space S1, etc. The contents and auxiliary contents can be taken in various ways.

[0195] The above is only a part of the relevant description of the preferred embodiments that can be implemented by the present invention. It is well known that the scope of the present invention should not be limited to the above-mentioned embodiments. The technical ideas of the present invention described above and its fundamental technical ideas are all included in the scope of the present invention.
