Specifically, the second fitting part <NUM> may include a pair of primary protrusions that maintain a state in which the head portion <NUM> is fitted before the separation portion <NUM> is separated from the body part <NUM>, and a pair of secondary protrusions on which the head portion <NUM> moves upward after the separation part <NUM> is separated from the body part <NUM> and then passes to be hooked.

A coupling structure of the separation part and the fixing part according to the ninth embodiment is an embodiment in which the structures illustrated in <FIG> are arranged and connected in the circumferential direction rather than the vertical direction.

Specifically, as illustrated in <FIG>, the separation part <NUM> has a belt structure coupled to the cover part <NUM> and the body part <NUM> by a plurality of bridges (not shown) and may be inserted into and fixed to the fixing part <NUM> formed on any one circumferential surface of the cover part <NUM> and the body part <NUM> after being separated from the cover part <NUM> and the body part <NUM>.

Here, at least a portion of the outer circumferential surface of the cover part <NUM> and the fixing part <NUM> may be cut in a portion at which the separation part <NUM> is disposed so that the separation part <NUM> is installed.

In addition, for the convenience of the separation of the separation part <NUM>, a separation handle <NUM> held by the use may be formed at an end portion of the separation part <NUM>.

The separation part <NUM> may be integrally connected to a side, at which the fixing part <NUM> is formed, of the cover part <NUM> and the body part <NUM> by a first connection part <NUM> so that an end close to the fixing part <NUM> is folded in the circumferential direction.

The fixing part <NUM> may be formed at the side, to which the separation part <NUM> is connected, of the cover part <NUM> and the body part <NUM> and may have any configuration as long as the separation part <NUM> is fixed.

For example, the fixing part <NUM> may have a structure in which a through-hole to be fitted in the circumferential direction is formed in consideration of the separation part <NUM> of the belt structure.

The cover part <NUM> may be hingedly coupled to the body part <NUM> by a hinge part <NUM> so that the user easily separates the cover part <NUM> from the body part <NUM>. Here, a handle part <NUM> disposed at a position opposite to the hinge part <NUM> may be formed so that the handle part <NUM> is disposed opposite to the hinge part <NUM>.

In the container cap <NUM> according to the present invention, at least one of the separation part <NUM> or the fixing part <NUM> may be disposed at positions opposite to the hinge part <NUM> described above, and the separation part <NUM> and the fixing part <NUM>, which are coupled to each other, may be used as a handle for opening the container <NUM> by separating the cover part <NUM> from the body part <NUM> due to the user's manipulation.

The container cap <NUM> having the above configuration may be formed by injecting a synthetic resin material.

Here, in the container cap <NUM> according to the present invention, it is preferable that the body part <NUM>, the cover part <NUM> and the separation part <NUM> are integrally formed in consideration of manufacturing convenience and recycling after use.

The container cap <NUM> having the above configuration may be coupled to containers having various structures.

Particularly, the container cap <NUM> according to the present invention is suitable for a container <NUM> containing powder, in particular, contents having a granular structure, and the container <NUM> structure may also be specialized in discharging the contents having the granular structure.

In the container <NUM> illustrated in <FIG>, a partition member <NUM> forming a discharge passage <NUM> of the contents may be installed.

The partition member <NUM> may be installed inside the container <NUM> to form the discharge passage <NUM> of the contents and may have various configurations.

For example, the partition member <NUM> may form a content communication passage <NUM> communicating with the discharge passage <NUM> at a lower end thereof.

The partition member <NUM> may form two passages at an upper end thereof, that is, a discharge passage <NUM> and an inflow passage <NUM> through which the contents are introduced, and as illustrated in <FIG>, when it is inclined more than a horizontal line, it is necessary to block the discharge of the contents from being discharged through the inflow passage <NUM>.

For this, the container <NUM> may be installed at an upper end of the inflow passage <NUM>, and a door member <NUM> for opening and closing the inflow passage <NUM> according to an inclined angle of the container <NUM> may be rotatably installed.

The door member <NUM> may be a configuration that is installed at the upper end of the inflow passage <NUM> to open and close the inflow passage <NUM> according to the inclined angle of the container <NUM> and may have various configurations.

Here, the door member <NUM> has to be installed by being supported inside the container <NUM>. Here, the hinge part <NUM> to which the door member <NUM> is coupled to enable hinge rotation is coupled to the door member <NUM>, and the door member <NUM> may be coupled to the inner circumferential surface of the container <NUM> by an installation coupling part <NUM> coupled to a support coupling part <NUM> formed on the inner circumferential surface of the container <NUM>.

In addition, in order to prevent the door member <NUM> from excessively rotating when the door member <NUM> rotates, a hook part <NUM> with which the door member <NUM> is hooked to prevent the door member <NUM> from excessively rotating may be formed on an upper end of the partition member <NUM>.

In the container <NUM>, the contents having the granular structure have to be smoothly discharged toward the discharge passage <NUM>, and thus, a bottom structure thereof may have various structures as illustrated in <FIG>.

Specifically, in the container <NUM>, an apex portion <NUM> may protrude from an end thereof so that the contents having the granular structure are discharged toward the discharge passage <NUM>.

The apex portion <NUM> may be a configuration in which the apex portion <NUM> protrudes from the end thereof so that the contents having the granular structure are discharged toward the discharge passage <NUM>, and it is preferable that a height H of the apex portion <NUM> is greater than <NUM>/<NUM> of a diameter D of a lower end of the container <NUM> to improve a formation effect.

Since the apex portion <NUM> is formed, an inclined surface <NUM> that is inclined toward a lower edge of the container <NUM> may be formed to guide the contents to the lower edge of the container <NUM>.

In addition, as illustrated in <FIG> and <FIG>, and <FIG>, the apex portion <NUM> may be formed in a symmetrical structure at a center thereof.

Particularly, the apex portion <NUM> may be asymmetrical to induce the content so as to flow toward the discharge passage <NUM> and may be preferably formed far from the discharge passage <NUM> as illustrated in <FIG> and <FIG>, <FIG> and <FIG>.

Here, a plurality of ribs <NUM> protruding upward from a bottom surface may be formed on the inclined surface <NUM> to guide the movement of the contents.

The plurality of ribs <NUM> may be a portion that is formed to protrude upward from the bottom surface on the inclined surface <NUM> to guide the movement of the contents and may be formed in various structures as illustrated in <FIG>.

In the container <NUM>, when external air or the like is introduced into the inside, deterioration of the contents may occur. Thus, it is preferable that the container cap <NUM> coupled to the container inlet <NUM> has a blocking structure for maximally blocking the container inlet <NUM> to prevent the external air from being introduced.

Thus, at least one of the cover part <NUM> or the container inlet <NUM> may include a plurality of close contact parts that are in close contact with the container inlet <NUM>. The close contact part may have a close curve surrounding the container inlet <NUM> to prevent the external air from being introduced from the outside into the container <NUM>.

Particularly, the blocking structure for sealing the inside of the container <NUM> is preferably provided in the cover part <NUM> coupled to the upper end of the container inlet <NUM>.

According to the invention, the cover part <NUM> includes an inner ring <NUM>, a so-called ring gasket, which protrudes from the bottom surface and is inserted into the inner circumferential surface of the container inlet <NUM> in order to increase in sealing force of the container <NUM>.

The inner ring <NUM> may be a portion that protrudes from the bottom surface of the cover part <NUM> and is inserted into the inner circumferential surface of the container inlet <NUM> in order to increase in sealing force of the container <NUM> and may have various configurations according to the contact structure with the container inlet <NUM>.

The cover part <NUM> may be coupled to a snap-type coupling structure (e.g., one piece and two piece one touch cap and undercut cap structure).

Here, the snap-type coupling structure refers to a structure in which a circular ring is formed to protrude from the outer circumferential surface of the container inlet <NUM>, and a ring-shaped hook protrusion hooked with the circular ring of the container inlet <NUM> is formed on the inner circumferential surface of the container cap <NUM>.

Also, a screw coupling structure refers to a structure in which a male screw is formed on the outer circumferential surface of the container inlet <NUM>, and a female screw screw-coupled to the male screw is formed on a portion of the inner circumferential surface of the container cap <NUM> so as to be coupled.

Here, in the container inlet <NUM>, one or more ring-shaped coupling protrusions <NUM> may be formed on the outer circumferential surface, and the cover part <NUM> may be coupled to the container inlet <NUM> because the ring-shaped coupling protrusion <NUM>, into which the coupling protrusion <NUM> formed on the container inlet <NUM> is inserted, is formed on the inner circumferential surface.

Also, the body part <NUM> coupled to the cover part <NUM> may have various coupling structures such as screw coupling or snap coupling with respect to the container inlet <NUM>.

The cover part <NUM> may be provided with a plurality of close contact parts that are in close contact with the container inlet <NUM> by relatively close contact with the container inlet <NUM>.

Also, each of the close contact parts may have a closed curve surrounding the container inlet <NUM> in order to block the inflow of the external air into the container <NUM> from the outside and may have various configurations.

Hereinafter, the blocking structure will be described in detail with reference to a more specific embodiment. Also, for the convenience of description, characteristic portions will be described in detail.

In addition, although the blocking structure has been described for each embodiment, one or more embodiments may be combined in a range that does not conflict with each other.

As illustrated in <FIG>, the cover part <NUM> may be provided with one or more inner circumferential-side protrusions <NUM> protruding toward the inner ring <NUM> to be in contact with an outer circumferential surface of the inner ring <NUM> when the cover part <NUM> is coupled to the container inlet <NUM>.

Each of the inner circumferential-side protrusions <NUM> may be a portion protruding toward the inner ring <NUM> so as to be in contact with the outer circumferential surface of the inner ring <NUM> and may have a ring shape in the circumferential direction with respect to a central axis in a longitudinal direction of the cover part <NUM>.

Also, it is preferable that the inner circumferential-side protrusion <NUM> is formed in a gentle curve so that a longitudinal cross-section of the container inlet <NUM> is in surface contact rather than line contact with the outer circumferential surface of the inner ring <NUM>.

The cover part <NUM> may have a configuration similar to the inner circumferential-side protrusion <NUM> described above and may be provided with one or more inner ring protrusions protruding toward the inner circumferential surface of the cover part <NUM> so as to be in contact with the inner circumferential surface of the cover part <NUM> when the cover part <NUM> is coupled to the container inlet <NUM>.

The inner ring protrusion may be a configuration protruding toward the inner circumferential surface of the cover part <NUM> so as to be in contact with the inner circumferential surface of the cover part <NUM> when the cover part <NUM> is coupled to the container inlet <NUM> and may have a ring shape in the circumferential direction with respect to the central axis in the longitudinal direction of the container inlet <NUM>.

Also, it is preferable that the inner ring protrusion is formed in a gentle curve so that a longitudinal cross-section of the container inlet <NUM> is in surface contact rather than line contact with the inner circumferential surface of the container inlet <NUM>.

In order to increase in sealing force for the container <NUM>, the cover part <NUM> may be inserted into the concave groove <NUM> formed integrally along the circumference at the upper end of the container inlet <NUM>, and when the cover part <NUM> is coupled to the container inlet <NUM>, a middle ring <NUM> formed on the bottom surface of the cover part <NUM> may be formed.

The middle ring <NUM> may be inserted into the concave groove <NUM> integrally formed along the circumference at the upper end of the container inlet <NUM> and may be a ring formed on the bottom surface of the cover part <NUM> when the cover <NUM> is coupled to the container inlet <NUM>, and also, the middle ring <NUM> may have various configurations.

For example, the middle ring <NUM> may form an inverted triangular shape or an inverted trapezoid shape in a vertical cross-section. Here, an end of the middle ring <NUM> may have various shapes such as a flat surface or a curved surface.

In addition, the concave groove <NUM> into which the middle ring <NUM> is inserted may be formed in a shape corresponding to the cross-sectional shape of the middle ring <NUM>, and also may be preferably formed so that a width thereof in the cross-sectional shape of the middle ring <NUM> is more reduced to be in close contact with the middle ring while the middle ring <NUM> is inserted.

The concave groove <NUM> and the middle ring <NUM> may be formed in two or more according to sealing force.

In the formation of the concave groove <NUM>, the concave groove <NUM> may be formed by two (inner and outer) upper ends <NUM> and <NUM> forming the upper end of the container inlet <NUM>.

Here, the two upper ends <NUM> and <NUM> are preferably formed in a structure having elasticity while forming an inclination at a portion constituting the concave groove <NUM>.

Also, it is preferable that at least one of the two upper ends <NUM> and <NUM> has a curved outer circumferential surface.

Here, as illustrated in <FIG>, the cover part <NUM> may have a slope <NUM> that is in contact with the curved outer circumferential surface of the upper ends <NUM> and <NUM> so that the cover part <NUM> and the container inlet <NUM> are in close contact with each other, i.e., one or more close contact parts are formed when the cover part <NUM> is coupled to the container inlet <NUM>.

In the upper end of the container inlet <NUM>, that is, the two upper ends <NUM> and <NUM>, the inner upper end <NUM> may be formed lower than the outer end <NUM> with respect to the concave groove <NUM>.

In the upper end of the container inlet <NUM>, as illustrated in <FIG>, in addition to or separately from the same or similar structure as in the first embodiment, one or more contact rings <NUM> and <NUM> extending from the lower end of the cover part <NUM> may be formed to extend so as to be in close contact with the upper end of the container inlet <NUM>.

The contact rings <NUM> and <NUM> may be portions extending from the lower end of the cover <NUM> so as to be in close contact with the upper end of the container inlet <NUM> and may have a ring shape.

Particularly, the contact rings <NUM> and <NUM> may be constituted by an inner ring <NUM> and an outer ring <NUM> so that the upper end of the container inlet <NUM> is fitted.

In the sealing of the cover part <NUM> and the container inlet <NUM>, when flexibility is provided to portions that are in contact with each other, the sealing force of the container may be greatly improved.

Thus, as illustrated in FIGS. 28a to 28d, one or more flexibility imparting grooves <NUM>, <NUM>, and <NUM> may be formed in the container inlet <NUM>, and pressing contact parts <NUM>, <NUM>, <NUM>, and <NUM> that are in press contact with positions corresponding to the flexibility imparting grooves <NUM>, <NUM>, and <NUM> may be formed on the cover part <NUM>.

The flexibility imparting grooves <NUM>, <NUM>, and <NUM> may be grooves formed to improve the sealing force of the container by imparting the flexibility to the portion at which the cover part <NUM> and the container inlet <NUM> are in contact with each other and may be formed at all portions at which the cover part <NUM> and the container inlet <NUM> are in contact with each other.

For example, as illustrated in <FIG> and <FIG>, the flexibility imparting grooves may be provided as flexibility imparting grooves <NUM> and <NUM> formed at the upper end of the container inlet <NUM>.

The flexibility imparting grooves <NUM> and <NUM> formed at the upper end of the container inlet <NUM> may be ring-shaped grooves formed at the upper end of the container inlet <NUM> and also may be provided as the concave groove <NUM> disclosed in the first embodiment.

Particularly, the flexibility imparting grooves <NUM> and <NUM> formed at the upper end of the container inlet <NUM> may be formed close to the inner circumferential surface (<FIG>) or the outer circumferential surface (<FIG>) at the upper end of the container inlet <NUM> so that deformation is allowable when being in contact with the cover part <NUM>.

As another example, when the flexibility imparting groove <NUM> formed at the upper end of the container inlet <NUM> is formed close to the inner circumferential surface at the upper end of the container inlet <NUM> as illustrated in <FIG>, the cover part <NUM> may press and be in contact with the portion in which the flexibility imparting groove <NUM> is formed as the pressing contact part <NUM> when the cover part <NUM> is coupled to the container inlet <NUM> by the formation of the inclined surface <NUM> at the position corresponding thereto.

When the flexibility imparting groove <NUM> formed at the upper end of the container inlet <NUM> is formed close to the outer circumferential surface at the upper end of the container inlet <NUM> as illustrated in <FIG>, the cover part <NUM> may press and be in contact with the portion in which the flexibility imparting groove <NUM> is formed as the pressing contact part <NUM> when the cover part <NUM> is coupled to the container inlet <NUM> by the formation of the inclined surface <NUM> at the position corresponding thereto.

In the formation of the pressing contact part <NUM> in the cover part <NUM>, as illustrated in <FIG> in addition to the simple inclined surface, the pressing contact part <NUM> may be formed on the outer ring <NUM> disclosed in the second embodiment.

As another example, as illustrated in <FIG>, the flexibility imparting groove <NUM> may be provided as the flexibility imparting groove <NUM> formed on the outer circumferential surface of the container inlet <NUM>.

Here, a ring-shaped flexibility imparting protrusion <NUM> may be formed on the outer circumferential surface of the container inlet <NUM> in order to form the flexibility imparting groove <NUM> pressed to the cover part <NUM>, and since the flexibility imparting groove <NUM> is formed to be concave from the upper side to the lower side in the flexibility imparting protrusion <NUM>, the flexibility imparting groove <NUM> may be formed.

In addition, the cover part <NUM> may be provided with a pressing contact part <NUM> formed on the inner circumferential surface of the cover part <NUM> to correspond to the flexibility imparting groove <NUM>.

The pressing contact part <NUM> may be formed as an inclined surface formed to be inclined upward to press a portion, in which the flexibility imparting groove <NUM> is formed, of the flexibility imparting protrusion <NUM> by descending of the cover part <NUM> when the cover part <NUM> is coupled to the container inlet <NUM>.

As described above, the pressing contact parts <NUM>, <NUM>, and <NUM> may be portions formed on the cover part <NUM> and pressed to be in contact with the flexibility imparting grooves <NUM>, <NUM>, and <NUM> at the corresponding positions and may have any structure as long as the portions in which the flexibility imparting grooves <NUM>, <NUM>, and <NUM> are pressed.

Specifically, the pressing contact parts <NUM>, <NUM>, and <NUM> may be preferably formed as an inclined surfaces in consideration that the cover part <NUM> rotates and/or descends with respect to the container inlet <NUM>, and the portions, in which the flexibility imparting grooves <NUM>, <NUM>, and <NUM> are formed, are pressed by force applied by the descending.

However, the pressing contact parts <NUM>, <NUM>, and <NUM> may have various structures such as protrusions in addition to the inclined surfaces as long as the portions in which the flexibility imparting grooves <NUM>, <NUM>, and <NUM> are formed are pressed by the force applied by the descent.

When the cover part <NUM> and the container inlet <NUM> are coupled, the portions that are in close contact with each other may intentionally increase to improve the sealing force of the container and may be implemented in various embodiments.

The cover part <NUM> may further include an auxiliary inner ring <NUM> between the upper end of the container inlet <NUM> and the inner ring <NUM> in contrast to the configuration illustrated in <FIG>.

The auxiliary inner ring <NUM> may be formed to protrude downward from the bottom surface of the cover part <NUM> between the upper portion of the container inlet <NUM> and the inner ring <NUM>.

Here, the auxiliary inner ring <NUM> may be preferably formed shorter than a vertical length of the inner ring <NUM> in order to prevent interference with the inner ring <NUM>.

Also, the auxiliary inner ring <NUM> may be preferable that a surface toward the upper end of the container inlet <NUM> is formed as an inclination. Here, the upper end of the container inlet <NUM> may also be preferably formed with an inclined surface as the pressing contact part <NUM> at the portions that are in contact with the auxiliary inner ring <NUM>.

As described in the first embodiment, the container inlet <NUM> may be provided with an inner circumferential-side protrusion <NUM> that is in contact with the outer circumferential surface of the inner ring <NUM>.

The above structure may increase in contact portion between the cover <NUM> and the container inlet <NUM> to improve the sealing force of the container.

As illustrated in <FIG>, a pressing contact part <NUM> for pressing the portion in which the flexibility imparting groove <NUM> may be formed as an inclined surface so that a partial-inner ring <NUM> instead of the configuration of the auxiliary ring <NUM> and an auxiliary inner ring <NUM> are integrated with each other.

In the embodiment illustrated in <FIG>, as illustrated in <FIG> with respect to the formation of the flexibility imparting groove <NUM> or the concave groove <NUM>, the flexibility imparting groove <NUM> or the concave groove <NUM> may be formed by the inner upper end <NUM> and the outer upper end <NUM>, and the inner upper end <NUM> and the outer upper end <NUM> may have the same height or heights different from each other.

Particularly, in <FIG>, the height of the inner upper end <NUM> may be less than that of the outer upper end <NUM>.

The flexibility imparting groove <NUM> may be formed close to the outer circumferential surface of the upper end of the container inlet <NUM>, as illustrated in <FIG>.

Here, the cover part <NUM> may have an inclined surface <NUM> as the pressing contact part <NUM> to press the portion in which the flexibility imparting groove <NUM> is formed.

In <FIG>, a height of the outer upper end <NUM> may be less than that of the inner upper end <NUM>.

Also, as illustrated in <FIG>, a protrusion 244a may be formed on the cover part <NUM> as the pressing contact part for pressing the portion in which the flexibility imparting groove <NUM> is formed.

In the improving of the sealing force of the container, it is preferable to relatively more increase in contact portion between the upper end of the container inlet <NUM> and the cover part <NUM>. Particularly, a plurality of contact parts may be preferably formed in plurality with respect to a passage from the outside of the container to the inside of the container rather than being connected to each other.

As a first example, as illustrated in <FIG>, in addition to the inner ring <NUM> and the inner protrusion <NUM> that are in contact with the outer circumferential surface of the inner ring <NUM> disclosed in the first embodiment, the cover part <NUM> may be additionally provided with an auxiliary inner ring <NUM> that is in close contact with the upper end of the container inlet <NUM>.

The auxiliary inner ring <NUM> may be formed to protrude downward from the cover part <NUM>, in particular, the bottom surface of the cover part <NUM> between the upper portion of the container inlet <NUM> and the inner ring <NUM>.

Also, it is preferable that the auxiliary inner ring <NUM> is formed so as to be in contact with the upper end of the container inlet <NUM> when the cover <NUM> is coupled to the container inlet <NUM>.

For this, it is preferable that the cross-section of the upper end of the container inlet <NUM> forms a curved surface, and an inner circumferential-side protrusion <NUM> on which the inner circumferential surface of the upper end of the container inlet <NUM> protrudes toward the inner circumferential surface of the auxiliary inner ring <NUM> may be formed.

As a second example, as illustrated in <FIG>, at least one surface of the surfaces on which the upper end of the auxiliary inner ring <NUM> and the container inlet <NUM> are in contact with each other in the structure illustrated in FIG. 39a may be provided as inclined surfaces <NUM> and 241a.

In the first and second examples, the auxiliary inner ring <NUM> may be between the upper end of the container inlet <NUM> and a wall portion <NUM> instead of the position between the upper end of the container inlet <NUM> and the inner ring <NUM> and the corresponding configurations may be formed symmetrical to each other.

As a third example, as illustrated in <FIG>, the flexibility imparting groove <NUM> may be additionally formed in the structure of <FIG>.

Here, an auxiliary protrusion <NUM> as illustrated in <FIG> may be formed on the inner circumferential surface of the container inlet <NUM>.

As a fourth example, as illustrated in <FIG>, the flexibility imparting groove <NUM> may be additionally formed in the structure of <FIG>.

As a fifth example, as illustrated in <FIG>, in the structure of <FIG>, an inclination may be formed from the upper end of the container inlet <NUM> to the inner circumferential-side protrusion <NUM>.

Specifically, the container inlet <NUM> may have an inclination in a direction in which an inner diameter decreases form the upper end to the inner circumferential-side protrusion <NUM>.

With the above structure, in the case in which the cover part <NUM> is coupled to the container inlet <NUM>, when the cover part <NUM> descends with respect to the container inlet <NUM>, the outer circumferential surface of the auxiliary ring <NUM> may be in close contact between the upper end of the container inlet <NUM> and the inner circumferential-side protrusion <NUM>.

Particularly, if the contact portions that are in contact with the upper end of the container inlet <NUM> and the cover <NUM> are improved, the sealing force of the container may be improved.

In the container according to the fifth embodiment of the present invention, as illustrated in <FIG> and <FIG>, the container inlet <NUM> may have a concave groove <NUM> at a center by an inner upper end <NUM> and an outer upper end <NUM> and have an inner inclined surface <NUM> and an outer inclined surface <NUM> on which the cover part <NUM> is in contact with the inner portion of the inner upper end <NUM> and the outer portion of the outer upper end <NUM>.

Specifically, the container inlet <NUM> may have a concave groove <NUM> formed at a center of the upper end by the inner upper end <NUM> and the outer upper end <NUM>.

Here, the inner portion of the inner upper end <NUM> and the outer portion of the outer upper end <NUM> may be formed as curved surfaces so as to be in close contact with the inner inclined surface <NUM> and the outer inclined surface <NUM>.

Also, a sidewall of the concave groove <NUM> may be preferably formed to be inclined upward so that the inner upper end <NUM> and the outer upper end <NUM> are easily deformed in a direction, in which the width thereof decreases, i.e., the inner upper end <NUM> and the outer upper end <NUM> are contracted.

In other words, each of the inner upper end <NUM> and the outer upper end <NUM> preferably has a 'V' shape.

The cover part <NUM> may have an inner inclined surface <NUM> and an outer inclined surface <NUM> that are in contact with an inner portion of the inner upper end <NUM> and an outer portion of the outer upper end <NUM>.

The inner inclined surface <NUM> and the outer inclined surface <NUM> may be portions formed on the cover part <NUM> so as to be in contact with the inner portion of the inner upper end <NUM> and the outer portion of the outer upper end <NUM> and may have various structures.

For example, the inner inclined surface <NUM> may be formed as a portion of the inner ring <NUM> as illustrated in <FIG> and <FIG>.

Also, the inner inclined surface <NUM> may be formed as a portion of the auxiliary inner ring <NUM> when the auxiliary inner ring <NUM> is provided.

As illustrated in <FIG>, he cover part <NUM> may be provided with an inner contact ring <NUM> and an outer contact ring <NUM> so that an opposite concave groove <NUM> is formed to allow the upper end of the container inlet <NUM> to be at least partially inserted.

The inner contact ring <NUM> and the outer contact ring <NUM> may be formed in the cover part <NUM> to form the opposite concave groove <NUM> so that the upper end of the container inlet <NUM> is at least partially inserted and may have various configurations.

For example, the inner contact ring <NUM> and the outer contact ring <NUM> may be formed to extend downward from the bottom surface of the cover part <NUM>.

Here, it is preferable that each of the inner contact ring <NUM> and the outer contact ring <NUM> have a curved surface that is in contact with the upper end of the container inlet <NUM>.

In addition, each of lower ends of the inner contact ring <NUM> and the outer contact ring <NUM> may be deformed in a direction in which a width of the opposite concave groove <NUM> is widened, that is, the sidewall of the opposite concave groove <NUM> may be preferably formed to have an upward inclination so that the inner contact ring <NUM> and the outer contact ring <NUM> are deformed to be spread with respect to each other.

In other words, it is preferable that each of the inner contact ring <NUM> and the outer contact ring <NUM> has an inverted 'V' shape toward the lower side.

It is preferable that the upper end of the container inlet <NUM> is sharply formed so as to be easily inserted into the opposite concave groove <NUM> formed by the inner contact ring <NUM> and the outer contact ring <NUM>.

Also, as illustrated in <FIG>, the upper end of the container inlet <NUM> may have inclined surfaces <NUM> and <NUM> expanded inward and outward with respect to the uppermost end so as to be easily inserted into the opposite concave groove <NUM>.

Referring to the above-described embodiments, it is preferable that the contact portion at which the cover part <NUM> and the container inlet <NUM> are in contact with each other increases, in particular, the contact portion between the upper end of the container inlet <NUM> and the cover part <NUM> relatively increases as a means of increasing in sealing force of the container.

Here, a plurality of contact parts may be preferably formed in plurality with respect to a passage from the outside of the container to the inside of the container rather than being connected to each other.

Particularly, in the formation of the plurality of contact parts, it is achieved by the deformation of the structure of the cover part <NUM> and the container inlet <NUM>, and it may be implemented by the formation of the inclined surfaces having various angles and structures, the flexibility imparting groove, and the like.

In addition, the structure of the plurality of contact portions may be changed by exchanging the structures of the cover part <NUM> and the container inlet <NUM> with each other.

Hereinafter, various modifications of the container inlet <NUM> for forming the plurality of contact portions in plurality based on a passage from the outside of the container to the inside of the container will be described.

As illustrated in <FIG>, the container inlet <NUM> may be provided with an inner upper end <NUM> and an outer upper end <NUM> at the upper end centering on the concave groove <NUM>.

Here, the concave groove <NUM> may be formed close to the inner side or the outer side, and thus, any one of the inner upper end <NUM> and the outer upper end <NUM> may have a width less than that of the other one so as to be easily deformed by being in contact with the cover part <NUM>.

In addition, heights of the inner upper end <NUM> and the outer upper end <NUM> may be the same as or different from each other.

<FIG> illustrates a case in which the width of the inner upper end <NUM> is less than that of the outer upper end <NUM>.

In addition, the concave groove <NUM> may be formed to increase in width as it goes upward.

<FIG> is a modified example of the container inlet <NUM> illustrated in <FIG>.

The container inlet <NUM> illustrated in <FIG> may be formed so that the height of the inner upper end <NUM> is greater than that of the outer upper end <NUM>.

Furthermore, a fine ring protrusion <NUM> may be formed to increase in contact portion with the cover part <NUM> on the inner circumferential surface of the container inlet <NUM>.

The container inlet <NUM> illustrated in <FIG> may be further provided with a central protruding upper end <NUM> protruding upward from the concave groove <NUM> of <FIG>.

Particularly, the central protruding upper end <NUM> may be formed higher than the height of each of the inner upper end <NUM> and the outer upper end <NUM>, and the concave groove <NUM> may be formed by forming two divided concave grooves 220a and 220b.

Here, it is preferable that the cover part <NUM> coupled to the container inlet <NUM> has a ring-shaped groove into which the central protruding upper end <NUM> is inserted.

In the container inlet <NUM> illustrated in <FIG>, the inner upper end <NUM> may be formed higher than the outer upper end <NUM> and may have a stepped portion <NUM> that is smaller than each of the inner upper end <NUM> and the outer upper end <NUM> at the inside thereof.
