Description

Technical Field

[0001] The present invention relates to a sealed container, in particular to a sealed cover and a sealed container which are easy to manufacture, convenient to use and easy to open. Background Art

[0002] In order to store food hygienically and prolong the storage period, sealed containers are widely used. In a commonly used sealed container, one or more protrusions are formed on the container body, and one or more locking wings having a locking portion configured to engage with the protrusions are formed on the cover. In the case of such a sealed container, the user can close the sealed container by rotating the locking wing of the cover downward so that the locking portion of the locking wing is locked to the protrusion, and can open the sealed container by rotating the locking wing of the cover upward so that the locking between the locking portion of the locking wing and the protrusion is released.

[0003] In such a sealed container, it is necessary to form a protrusion on the container body so that it can be firmly engaged with the locking portion of the locking wing, and to form it along the entire upper part of the container body or on all four sides of the container body so that the cover can be coupled to the container body regardless of direction. That is, there is a disadvantage that the cover cannot be normally used with containers other than the container body manufactured to include the protrusion, and the utilization rate is quite low.

[0004] In addition, the portion protruding from the surface of the container body may make it difficult to clean the portion. That is, since the upper and lower portions of the protrusion form a sharp gap relative to the container body, special care may be required when cleaning the portion. When the sealed container is used to store food, etc., there is a concern that it may cause hygiene problems. This is because the protrusion is formed around the opening portion in the upper portion of the container body and is the portion that requires the most cleanliness. Despite this, the cleanliness level of this portion is particularly poor. In addition to this, the protrusion of the container body becomes a factor that makes it inconvenient to store and carry the container, and even after the locking portion of the lid is separated, it may become a hindrance during use, such as colliding with the lid and locking wings.

[0005] On the other hand, considering the manufacturing aspect of the sealed container, in the sealed container using the locking wing, the locking portion of the locking wing and the protrusion of the container body must be precisely engaged before use, so a more sophisticated manufacturing method is required. Since general storage containers are made of materials such as glass, porcelain, and stainless steel, and the manufacturing tolerance of these materials can be as high as + / -2mm, the possibility of the locking portion and the protrusion not being able to engage properly in the above-mentioned prior art is bound to be high. Summary of the invention

[0006] Technical issues

[0007] Therefore, the present invention is proposed to solve the above-mentioned problems. One aspect of the present invention is to provide a sealed lid and a sealed container which can be used even in a container body without a protrusion and is easy to manufacture, use and open.

[0008] Other objects of the present invention will become more apparent from the embodiments described below.

[0017] The sealing cover may further include a locking protrusion extending inward from the lower portion of the cover edge. When the container body includes a body edge whose outer diameter at a first point is formed to be larger than the outer diameter at a second point lower than the first point, the locking protrusion may include an inclined surface contacting the first point and the second point when the sealing cover is coupled to the container body.

[0018] The cross section of the container body may be a circle, a polygon, or a combination of a circle and a polygon.

[0019] The sealing cover may include a plurality of flaps.

[0020] At least a portion of the contact support surface, the contact portion, and the support protrusion may be replaceably coupled to the wing. In this case, at least a portion of the contact support surface, the contact portion, and the support protrusion may have a lower elastic modulus than the wing.

[0035] Figure 1 FIG. 1 is a perspective view exemplarily showing a sealed container 1000 according to an embodiment of the present invention. Figure 2 This is a three-dimensional view of the container bodies 500a and 500b of the sealed container 1000 as viewed from above. Figure 3 This is a perspective view of the sealed cover 100 as viewed from below.

[0036] Reference Figures 1 to 3 A sealed container 1000 according to an embodiment of the present invention may include a sealed cover 100 and a container body 500 , and the sealed cover 100 may be detachably coupled to an opening portion 550 of the container body 500 to seal the interior of the container body 500 .

[0037] First, refer to Figure 2 The container body 500 may form an internal space, and the internal space may be opened through an opening 550 formed at the upper portion. For ease of description, the portion around the opening 550 in the container body 500 is referred to as a body edge 510, and the outer diameter of the portion with the largest outer diameter in the body edge 510 is referred to as a first outer diameter.

[0038] exist Figure 2 In the container body 500a shown in (a), a second outer diameter portion 520 having a second outer diameter smaller than the first outer diameter is formed below the body edge 510, and a third outer diameter portion 530a below the second outer diameter portion 520 has an outer diameter smaller than the second outer diameter.

[0039] On the other hand, Figure 2 In the container body 500b shown in (b), the body edge 510 is formed in the same manner as the second outer diameter portion 520, but the third outer diameter portion 530b has an outer diameter larger than the second outer diameter. Figure 2 The container body 500b shown in (b) can be manufactured, for example, by blow molding. When blow molding is utilized, the container body 500b can include a portion having an outer diameter larger than the first point of the body edge 510 (for example, a portion having a first outer diameter) below the body edge 510.

[0040] like Figure 2 As shown, in the structure where the container body 500 includes the second outer diameter portion 520 below the body edge 510, the body edge 510 may have a first point 512 (see Figures 5 to 7 ) is lower than the outer diameter of the second point 517 (refer to Figures 5 to 7 ) has a large outer diameter. A sealed container 1000 according to an embodiment of the present invention may include Figure 2For example, even if the first point 512 and the second point 517 of the body edge 510 are not naturally inclined or curved but form a sharp protrusion or boss, the first point 512 having a larger outer diameter at a higher position and the second point 517 having a smaller outer diameter at a lower position can also be realized.

[0041] In addition, the main body edge 510 of the container body 500 does not necessarily have a shape with a reduced outer diameter at the second point 517 compared to the first point 512. Even if the main body edge 510 maintains the same outer diameter over a predetermined length in the up and down directions, it can also be combined with the sealed cover 100 of an embodiment of the present invention.

[0042] Since the sealing cap 100 can be applied even when the body rim 510 maintains the same outer diameter, the sealing cap 100 according to an embodiment of the present invention can be applied to a wide variety of container bodies 500. The cross section of the container body 500 can be circular, polygonal, a combination of circular and polygonal shapes, and other various shapes, and even the cross section of the body rim 510 can be circular or polygonal.

[0043] Reference Figure 3 The sealing cover 100 may be detachably coupled to the opening 550 of the container body 500, and may be configured to seal the interior of the container body 500 when the sealing cover 100 is coupled to the container body 500. The sealing cover 100 may include all or part of the cover body 110, the cover edge 120, the internal rib 130, the cover boss 140, the clearance groove 150, the locking protrusion 160, the hinge seat 170, the bent portion 180, and the wing 190. The wing 190 may further include a support protrusion 200 and a contact portion 210, and the contact portion 210 may include a contact support surface 220.

[0044] The cover body 110 is a part that is configured to cover the opening 550 of the container body 500, and can occupy the largest area of ​​the sealed cover 100 under normal circumstances. It can be configured to be flat as a whole, but can also be implemented in various shapes as needed. In some embodiments, a transparent material can be used for all or part of the cover body 110. Since the cover body 110 plays the role of covering the opening 550 of the container body 500, the diameter of the cover body 110 can be greater than the outer diameter of the body edge 510.

[0045] The cover edge 120 may extend downward from the edge of the cover body 110. The internal rib 130 may extend downward with a smaller diameter inside the cover edge 120, and preferably, the outer diameter of the internal rib 130 may be formed smaller than the opening 550 of the container body 500. When the user combines the sealed cover 100 with the container body 500, the body edge 510 of the container body 500 may be inserted between the cover edge 120 and the internal rib 130 of the sealed cover 100. On the cover edge 120, a locking protrusion 160 may be formed at a desired position, and when a hole 135 is formed at a position corresponding thereto in the internal rib 130, injection molding using a sliding core mold may be adopted in the manufacture of the sealed cover 100.

[0046] The boss 140 may be formed at the edge of the cover body 110 at the inner side of the cover rim 120. The boss 140 may form a seal groove 145 for inserting a seal (not shown) together with the inner rib 130. When the user couples the sealed cover 100 to the container body 500, the seal (not shown) of the container body 500 may press the body rim 510 to seal the inside of the container body 500.

[0047] The clearance groove 150 is a portion corresponding to the groove formed on the cover edge 120. Figure 3 As shown, in order to prevent the cover edge 120 from obstructing the movement of the contact portion 210 when the user moves the flap 190 , a clearance groove 150 may be formed in the cover edge 120 at a position corresponding to the support protrusion 200 and the contact portion 210 .

[0048] The locking protrusion 160 may be formed to extend inward from the lower portion of the cover edge 120 at a specific position. Figure 3 In the embodiment shown, the lower surface of the locking protrusion 160 is flat on a horizontal plane parallel to the cover body 110, and the upper portion of the locking protrusion 160 forms an inclined surface 165. Figure 2 As described above, when the body edge 510 has a shape in which the outer diameter decreases at the second point 517 lower than the first point 512, the locking protrusion 160 may be configured to contact the first point 512 and the second point 517 of the body edge 510. In some embodiments, the locking protrusion 160 may contact the first point 512 and the second point 517 of the body edge 510 through the inclined surface 165. In particular, when the cross section of the body edge 510 has a shape in which the outer diameter decreases from the first point 512 toward the second point 517, the inclined surface 165 of the locking protrusion 160 may be formed in a shape corresponding to the inclination of the body edge 510.

[0049] Of course, the locking protrusion 160 does not necessarily have the inclined surface 165 in order to contact the first point 512 of the body edge 510 and the second point 517 located below the first point 512. The locking protrusion 160 may also have a shape bent into an L shape, for example. In some embodiments, the locking protrusion 160 may extend only in the horizontal direction and contact only the second point 517 with a reduced outer diameter below the first point 512 in the body edge 510. As described above, when the body edge 510 maintains the same outer diameter over a predetermined length in the up-down direction, the locking protrusion 160 may correspondingly have a shape having the same inner diameter over a corresponding length in the up-down direction.

[0050] Figure 3 The example in which the sealed cover 100 includes one fin 190 and two latching protrusions 160 is shown, but the number and position of the fins 190 and the latching protrusions 160 may be different. In particular, in some embodiments in which the sealed cover 100 includes a plurality of fins 190, the latching protrusions 160 may be omitted.

[0051] The hinge seat 170 may extend outward from the cover body 110, and specifically, may extend outward from a designated position on the outer surface formed by the cover body 110 and the cover edge 120. Figure 3 As shown, in a preferred embodiment of the present invention, the wing 190 may be connected to a pair of hinge seats 170 , and the clearance groove 150 may be formed between the pair of hinge seats 170 .

[0052] The bent portion 180 is a portion where the wing 190 is connected to the hinge seat 170, and the wing 190 can be connected to be relatively rotatable relative to the hinge seat 170. The bent portion 180 can be formed along a straight line so that the wing 190 can be easily rotated. In some embodiments, the hinge seat 170 and the wing 190 can be integrally formed of the same material. In this case, the bent portion 180 can be formed to have a thickness that allows the rotation of the wing 190 while providing sufficient strength to prevent it from being easily damaged.

[0053] The wing 190 is a portion that is connected to the hinge seat 170 so as to be relatively rotatable via the bent portion 180 provided on one side. A support protrusion 200 is provided on the same side of the wing 190 as the bent portion 180. Figure 3 As shown, when the wing 190 is lifted, the sealed cover 100 can be separated from the container body 500. When the wing 190 is rotated downward, the contact portion 210 formed at the end of the support protrusion 200 is in close contact with the container body 500, so that the sealed cover 100 can be combined with the container body 500.

[0054] As mentioned above, in some embodiments not shown, the sealed cover 100 may include a plurality of fins 190, and these may be connected to a plurality of hinge seats 170 formed at different positions from each other. When a sufficient number of fins 190 are provided, the sealed cover 100 may not include the locking protrusion 160.

[0055] The support protrusion 200 may extend from the same side of the wing 190 as the side where the bent portion 180 is provided in a direction toward the cover body 110. A contact portion 210 may be provided at the end of the support protrusion 200. When the user rotates the wing 190 downward, the support protrusion 200 and the contact portion 210 provided thereon pass through the clearance groove 150, and thus can move without being stuck to the cover edge 120.

[0056] The contact portion 210 is formed at the end of the support protrusion 200 and is configured to contact the container body 500. In particular, when the flap 190 is fully rotated downward, a contact support surface 220 may be formed at the portion where the contact portion 210 contacts the container body 500. For reference, the contact portion 210 may be formed to have a size that is pressed against the body edge 510 during the downward rotation of the flap 190. For example, when the flap 190 is rotated to a specified angle during the downward rotation relative to the hinge seat 170, the end of the contact portion 210 may contact the container body 500. When a greater force is applied to the flap 190 in this state, at least one of the contact portion 210, the support protrusion 200, and the bent portion 180 is elastically deformed, and a locking process in which the contact portion 210 passes over and through the portion where the pressing contact occurs may be performed. This structure enables the sealed cover 100 to be in a state of being more securely locked to the container body 500.

[0057] The contact support surface 220 is a part of the contact portion 210, and can be configured so that when the flap 190 is rotated downward relative to the hinge seat 170, the contact support surface 220 is in close contact with the container body 500. As described above, when the body edge 510 of the container body 500 has a larger outer diameter at the first point 512 and has a smaller outer diameter at the second point 517 at a position lower than the first point 512, it can be configured so that when the sealed cover 100 is coupled to the container body 500, the contact support surface 220 is in contact with both the first point 512 and the second point 517.

[0058] In some embodiments, the wing 190, the support protrusion 200, the contact portion 210 and the contact support surface 220 can be integrally formed from the same material. In this case, the contact portion 210 and the contact support surface 220 can be formed to have a material and size for achieving the aforementioned locking process and maintaining an effective sealing state.

[0059] On the other hand, in some embodiments, at least a portion of the support protrusion 200, the contact portion 210, and the contact support surface 220 may be formed of a material different from that of the fin 190. For example, in one embodiment of the present invention, the material used in the contact support surface 220 may have a lower elastic coefficient than the material used in the fin 190. The so-called elastic coefficient of a certain material lower than that of the comparison object means that the material is more likely to be elastically deformed than the comparison object. When the contact support surface 220 has a lower elastic coefficient, the contact support surface 220 can be better attached to the surface of the container body 500. For example, when plastic such as polypropylene (PP) is used as the material of the fin 190, a rubber material such as silicon having a lower elastic coefficient can be used in the contact support surface 220. For another example, in one embodiment of the present invention, the material used in the contact portion 210 and / or the support protrusion 200 may have a lower elastic coefficient than the material used in the fin 190. In this case, the aforementioned locking process can be performed more easily.

[0060] In some embodiments, at least a portion of the support protrusion 200, the contact portion 210, and the contact support surface 220 may be configured to be bonded to the fin 190. This allows different materials to be used for the above-mentioned components, and worn or damaged portions may be replaced as needed.

[0061] Refer to the following Figures 4 to 7 A process of sealing the sealed container 1000 according to an embodiment of the present invention will be described. Figures 4 to 6 are diagrams showing a process of sealing a sealed container 1000 according to an embodiment of the present invention, Figure 7 The cross-sectional view is an enlarged view of the contact portion 210 in the sealed container 1000 of one embodiment of the present invention. For reference, the term "reference line" is used in this specification, and the reference line L refers to a virtual line extending from the center of the cover body 110 to the center of the contact support surface 220 in the horizontal direction. Figures 4 to 6 The cross-sectional view shown in FIG. 2 (b) is a cross-sectional view taken along the line AA shown in the plan view of FIG. 2 (a), and a portion of AA is parallel to the reference line L.

[0062] First, the structure of the sealed cover 100 can prevent the inner surface of the cover body 110 from contacting a surface such as a table when the sealed cover 100 is in a state of being separated from the container body 500. Since the cover edge 120 extends downward from the cover body 110, it can first contact the surface of the table, etc., and the cover body 110 can be kept horizontal. This can prevent the inner surface of the cover body 110 from being contaminated by foreign matter, and conversely, it can also prevent the contents of the sealed container 1000 that may stick to the inner surface of the cover body 110 from contaminating a surface such as a table.

[0063] Reference Figure 4When the sealed container 1000 is closed, the user can place the sealed lid 100 above the container body 500, and the body edge 510 will be located between the lid edge 120 and the internal rib 130. Here, when viewed with the fin 190 as a reference, the sealed lid 100 can be located slightly backward from the container body 500 (at Figure 4 (b), the left side in the figure) is in a retreated state.

[0064] exist Figure 4 In the state shown, the locking protrusion 160 has not yet completely contacted the body edge 510. For reference, the position where the locking protrusion 160 is formed in the sealed cover 100 is preferably located within a range of more than 90 degrees to the left and right (i.e., a range of 180 degrees on the opposite side of the wing 190) with the reference line L as the center. Even in the state where the locking protrusion 160 has not yet contacted the body edge 510, since the internal rib 130 is formed to be slightly smaller than the opening 550 of the container body 500, the sealed cover 100 can maintain a stable posture.

[0065] Figure 5 The state in which the user is in the process of rotating the wing 190 downward is shown. Figure 5 In the embodiment, the locking protrusion 160 may not be in close contact with the body edge 510. On the other hand, when the wing 190 rotates downward, the contact portion 210 formed at the end of the supporting protrusion 200 contacts the surface of the container body 500.

[0066] Reference Figure 5 FIG. 5 is an enlarged view of FIG. (b), showing a first point 512 having a larger outer diameter at a higher position on the body edge 510 and a second point 517 having a smaller outer diameter at a lower position. In the body edge 510, the first point 512 and the second point 517 are naturally connected, so that their cross-sections can form an inclination or curve.

[0067] exist Figure 5 The enlarged view of FIG. (b) also shows that the upper portion of the contact portion 210 overlaps a portion of the body edge 510, which is to indicate the position of the contact portion 210 together with the body edge 510 when no elastic deformation occurs in any portion of the sealed cover 100. That is, when the sealed cover 100 does not elastically deform, the contact portion 210 will be stuck to the body edge 510, and the wing 190 will not be able to rotate downward all the way.

[0068] However, as mentioned above, at least a portion of the sealed cover 100 may be formed of a material that can be elastically deformed, and when at least one of the contact portion 210, the support protrusion 200, and the bent portion 180 is elastically deformed, the contact portion 210 may pass through the portion that is in press contact with the body edge 510. Specifically, when the user rotates the wing 190 downward and the wing 190 is rotated to a predetermined angle, the end of the contact portion 210 may contact the container body 500, for example, Figure 5 In this state, when the user applies a greater force to the wing 190, the contact portion 210 is pressed against the body edge 510. Due to the pressing force, when at least one of the contact portion 210, the support protrusion 200 and the bent portion 180 is elastically deformed, the contact portion 210 can pass over and through the portion where the pressing contact occurs.

[0069] Figure 6 The figure shows a state where the contact portion 210 passes through the pressed portion and the flap 190 rotates 90 degrees. As described above, in a state where the upper end of the contact portion 210 contacts the surface of the body edge 510, as the user continues to press the flap 190 downward, the contact portion 210 can pass through the pressed contact state where it is stuck on the body edge 510. A clearance groove 150 is formed in the cover edge 120 of the sealed cover 100 at a position corresponding to the support protrusion 200 of the flap 190, so that the contact support surface 220 of the contact portion 210 can pass through the clearance groove 150 and be in close contact with the body edge 510.

[0070] In particular, in this state, when the body edge 510 is pressed against the support surface 220, the cover body 110 can be pulled along the reference line toward the wing 190. As a result, Figure 6 As shown in (b), the locking protrusion 160 can be in close contact with the body edge 510. As described above, the locking protrusion 160 can be in close contact with only the first point 512 of the body edge 510, or only the second point 517, or both the first point 512 and the second point 517. When the cover body 110 is pulled toward the wing 190, the seal (not shown) inserted into the seal groove 145 can be aligned with the upper part of the body edge 510, so that the opening 550 is completely sealed.

[0071] Refer to the following Figure 7 The principle of the sealing cover 100 in accordance with an embodiment of the present invention being closely attached to the container body 500 is described in more detail. Figure 7 This is a cross-sectional view showing an enlarged contact portion 210 in a sealed container according to an embodiment of the present invention.

[0072] Figure 72 shows an example of the contact support surface 220 of the contact portion 210 contacting the first point 512 and the second point 517 of the body edge 510, and four intervals A, B, C, and D are shown with the first point 512 as the center. The four intervals A, B, C, and D are used to illustrate the possible positions of the bending portion 180 based on the point where the contact support surface 220 and the body edge 510 meet. The interval A represents the inner upper part, the interval B represents the inner lower part, the interval C represents the outer lower part, and the interval D represents the outer upper part. Figure 7 In the cross-sectional view of FIG. 1 , the horizontal direction is a direction parallel to the reference line L. The reference line L is a line extending from the center of the cover body 110 toward the center of the contact support surface 220 in the horizontal direction as described above.

[0073] exist Figure 7 In the structure shown, the body edge 510 applies a vertical resistance toward the outside to the contact support surface 220 of the contact portion 210 at the first point 512, so that the first point 512 acts as a pressing point, and the curved portion 180 is located at the lower part of the outside relative to the pressing point. In other words, the curved portion 180 is located at the lower side compared to the first point 512 that applies the vertical resistance toward the outside, and is located at the outside along the direction of the reference line L. That is, the curved portion 180 is located in the C section.

[0074] When viewed from a reference line L extending horizontally from the center of the cover body 110 toward the center of the contact support surface 220 , the bent portion 180 corresponds to an axis about which a portion including the contact support surface 220 and the contact portion 210 connected to the wing 190 rotates relative to the hinge base 170 .

[0075] Therefore, when the curved portion 180 is located in the C section, due to the contact between the contact support surface 220 and the body edge 510, the vertical resistance applied by the body edge 510 acts on the upper side of the curved portion 180 as the rotation axis, and can apply force in the direction of causing the wing 190 to rotate downward with the curved portion 180 as the center. Figure 7 As an example, the vertical resistance applied to the outer side of the contact support surface 220 at the first point 512 as the pressing point causes the wing 190 connected by the contact portion 210 and the support protrusion 200 to rotate clockwise around the bending portion 180. Figure 7 In the embodiment, since the clockwise rotation of the wing 190 is an action to lock the direction of the sealed cover 100, the sealed cover 100 can maintain a state of being coupled to the opening portion 550 of the container body 500.

[0076] exist Figure 7In the state shown, the body edge 510 exerts a vertical resistance force on the contact support surface 220 in the outward direction at the first point 512, so as to pull the sealing cover 100 relative to the container body 500 in the direction of the reference line L. Other flaps 190 or locking protrusions 160 are provided at positions other than the positions of the flaps 190 shown in the figure, and these can also be closely attached to the body edge 510. As a result, the sealing cover 100 is in a state of being fixed to the container body 500 in the horizontal direction.

[0077] On the other hand, when the body edge 510 includes a second point 517 having a smaller outer diameter at a position lower than the first point 512, the contact support surface 220 can also contact the second point 517 together. In this case, since the contact support surface 220 contacts the second point 517, that is, since it contacts the portion with a reduced outer diameter below the first point 512, the sealed cover 100 can also maintain a fixed state in the vertical direction. That is, when the sealed cover 100 is in the locked state, the contact support surface 220 is stuck to the upper part of the second point 517, thereby preventing the sealed cover 100 from opening.

[0078] However, as mentioned above, since the locked state of the sealed cover 100 can be maintained only by applying vertical resistance to the contact support surface 220 along the outer direction by the body edge 510 at the pressing point, the body edge 510 does not necessarily have a shape with a reduced outer diameter at the second point 517 compared to the first point 512, and the sealed cover 100 of an embodiment of the present invention can be combined even if the body edge 510 maintains the same outer diameter over a predetermined length in the up-down direction. In this case, the friction between the contact support surface 220 and the body edge 510 can play a role in fixing the sealed cover 100 in the vertical direction.

[0079] Although not shown in the figure, the case where the bend 180 is located in other intervals will be described below. In some embodiments, the bend 180 can be located in interval B. The intervals A, B, C, and D are divided based on the first point 512 in a vertical plane including the reference line L, so the case where the bend 180 is located in interval B can include, for example, in a circular cover body 110, the hinge seat 170 and the bend 180 are circumferentially away from the contact portion 210 (that is, the virtual line from the center of the cover body 110 to the bend 180 forms a large angle with respect to the reference line L). Of course, even in a structure where a portion that is recessed inward is formed on the cover body 110 and the body edge 510, and the bend 180 is formed in the recessed portion, the bend 180 can be located in interval B.

[0080] Even when the curved portion 180 is located in the B zone, due to the contact between the contact support surface 220 and the body edge 510, the vertical resistance applied by the body edge 510 acts on the upper side of the curved portion 180 as the rotation axis, and can apply force in the direction of rotating the flap 190 downward with the curved portion 180 as the center. The vertical resistance applied to the outer side of the contact support surface 220 at the first point 512 causes the flap 190 connected through the contact portion 210 and the support protrusion 200 to rotate downward with the curved portion 180 as the center, so that the state in which the sealed cover 100 is coupled to the opening 550 of the container body 500 can be maintained.

[0081] Although not shown in the figure, the body edge 510 applies a vertical resistance toward the outside and the bottom to the contact support surface 220 of the contact portion 210 at the second point 517, so that the second point 517 acts as a pressing point, and the curved portion 180 is located inside relative to the pressing point along the direction of the reference line L. This corresponds to the case where the curved portion 180 is located in the A section or the B section with respect to the second point 517 as a reference.

[0082] When the bending portion 180 is located in the B interval with respect to the second point 517 as a reference, the outer direction component of the vertical resistance applied to the contact support surface 220 at the second point 517 as the pressing point acts in a manner of rotating the wing 190 downward, thereby maintaining the sealed cover 100 in a connected state.

[0083] On the other hand, when the curved portion 180 is located in the A section with the second point 517 as a reference, the lower component of the vertical resistance applied to the contact support surface 220 at the second point 517 as the pressing point can act in the direction of pulling the cover body 110 outward and downward. In the state where the body edge 510 is interposed between the contact support surface 220 and the cover body 110, the vertical resistance at the pressing point pulls the contact portion 210 and the cover body 110 toward each other, so that the sealed cover 100 can maintain a fixed state in the horizontal direction and the vertical direction.

[0084] Of course, when the curved portion 180 is located in the A section or the B section with reference to the first point 512 or the second point 517, the vertical resistance on the pressing point can be partially applied in the direction of the upward rotating flap 190. Therefore, when the curved portion 180 is located in the A section or the B section, the size, shape and position of the hinge seat 170, the flap 190, the support protrusion 200, the contact portion 210 and the contact support surface 220 can be designed so that the vertical resistance component applied in the manner of closing the sealed cover 100 is greater than the vertical resistance component applied in the manner of opening the sealed cover 100.

[0085] The sealed cap 100 and the sealed container 1000 having the same according to an embodiment of the present invention can seal the container body 500 even when no protrusion is formed in the container body 500 , and this feature provides a wide variety of advantages.

[0086] First, the fact that no protrusion is required in the container body 500 means that the sealed cover 100 can be combined with a wide variety of existing container bodies 500, and thus the utilization of the sealed cover 100 can be greatly increased. In addition, since no protrusion is formed in the container body 500, the container body 500 is more convenient to carry and store, and the container body 500 is easy to clean, thereby making it easier to maintain a high cleanliness state of the container body 500. Even when the sealed cover 100 is opened, there is no possibility that the sealed cover 100 collides with or gets stuck on the protrusion of the container body 500, making it easier to open the sealed container 1000.

[0087] In terms of manufacturing, there is no need to form a protrusion on the container body 500, so the container body 500 can be basically manufactured into a simpler shape, and there are no parts such as protrusions and stoppers that require precise dimensional processing, so the allowable tolerance range can be greatly increased. The sealed cover 100 of an embodiment of the present invention can also be manufactured by relatively simple injection molding.

[0088] Although the present invention has been described above with reference to an embodiment, it will be appreciated by those skilled in the art that the present invention may be variously modified and altered without departing from the spirit and scope of the invention as described in the following claims.
