That is, the locking jaw 210 is caught on the fixing jaw formed on the outer circumferential surface of the upper inlet of the container body before the container is manufactured and first opened, so that the fixing ring 200 cannot be separated from the container body. And, the number, arrangement, shape, etc. of the locking protrusion 210 may vary according to the embodiment.

The connection part 300 is provided between the body 100 and the fixing ring 200 , and may be composed of a plurality of connection tips 310 for coupling the body 100 and the fixing ring 200 to each other.

Specifically, in the manufacturing stage of the container, the main body 100 and the fixing ring 200 may be manufactured as a bound body, and at this time, between the main body 100 and the fixing ring 200, both edges abut each other, that is, the main body. A connection part 300 may be provided on the circumference of the 100 and the fixing ring 200 . The connection part 300 may be configured such that a plurality of connection tips 310 are arranged at regular intervals or have different intervals, and each connection tip 310 connects the body 100 and the fixing ring 200 to each other. It may be formed in the shape of a bridge so as to allow it, and the number of connection tips 310 may be different depending on the embodiment, implementation, manufacturing environment, etc. (eg, 12, etc.).

On the other hand, the connection tip 310 may have various ductility (ductility) according to variables such as the type and composition ratio of the material, density, thickness, length, etc., and when a stress exceeding a predetermined limit acts, the connection tip A fracture occurs at 310 . That is, the connection tip 310 according to an embodiment of the present invention may be broken depending on the degree of stress applied.

Here, when a stress for opening the container opening and closing cap 10 according to an embodiment of the present invention is applied by the user, at least one of the plurality of connection tips 310 constituting the connection part 300 does not break. may not be Accordingly, since at least one connection tip 310 for coupling the body 100 and the fixing ring 200 to each other remains, the body 100 and the fixing ring 200 can maintain the state as a united body.

In this regard, in order to reinforce the coupling and maintenance of the fixing ring 200 to the main body 100, for example, a plurality of connection tips 310 during stress for opening the container opening and closing cap 10 are all In order to solve the problem of being broken and the fixing ring 200 remains in the container body, according to a further embodiment of the present invention, as shown in FIG. 2b , between the plurality of connection tips 310, the fixing ring 200 At least one additional tip 320 for maintaining engagement may be additionally provided. For reference, the width of the additional tip 320 may be substantially equal to or greater than the width of the connecting tip 310 .

In FIG. 2B, the configuration in which an additional tip 320 is provided in all of the spaces between the plurality of connecting tips 310 is exemplarily shown, but in another embodiment of the present invention, any one of the spaces between the plurality of connecting tips 310 or Only some of the additional tips 320 may be provided. By additionally providing an additional tip 320 in addition to the connection tip 310 that is generally provided between the body 100 and the fixing ring 200 , it is possible to more firmly maintain the coupling of the fixing ring 200 .

Problems can be prevented in advance. As a method of making the breaking strength of the connection tip 310 higher, for example, the cross-sectional area of the connection tip 310 is increased, or the connection part of the connection tip 310 and the main body 100 and the fixing ring 200 is increased. It may be various, such as implementing a round type.

With respect to the configuration for preventing at least one of the plurality of connection tips 310 from breaking when the opening stress of the container opening and closing cap 10 is applied, the container opening and closing cap 10 according to an embodiment of the present invention ) of the fixing ring 200, the fixing ring 200 is the body ( 100) and is characterized in that it is provided with a means to be separated integrally bound.

More specifically, the inlet portion located on the upper portion of the container body may be formed with a screw thread and a fixed jaw. As described above, the screw thread formed on the upper portion of the container body may be engaged with the screw thread formed on the body 100, and thus the container opening and closing cap 10 according to an embodiment of the present invention can rotate along the screw thread. let it be

The fixed jaw is provided on the lower part of the screw thread, and may be formed in a shape protruding outward along the circumferential direction from the side of the container inlet. At this time, since the fixed jaw protrudes more than a specific height, the locking jaw 210 formed in the fixing ring 200 may be caught by the fixed jaw.

The fixing ring 200 of the container opening/closing cap 10 according to an embodiment of the present invention may be provided with a means for preventing at least a portion of the locking jaw 210 from being caught on the fixing jaw, hereinafter FIGS. 2 to 6 . As will be described in turn in , these means can be implemented in many different ways.

On the other hand, by preventing at least a portion of the locking jaw 210 from being caught on the fixing jaw formed on the upper portion of the container body by the above-described means, the fixing ring 200 according to an embodiment of the present invention is the first opening of the container by the user. It can be separated from the container body integrally bound to the main body 100 at the time, and thus it is possible to efficiently solve the recycling problem after using the container. In the following specification of the present invention, among such means, the configuration and function of the cut-off line 250, the shielding film 260 (shown in FIG. 4), and the folded deformable part 220 (shown in FIG. 6) are more specifically and It will be described as an example.

First, the container opening and closing cap 10 according to an embodiment of the present invention is formed in the longitudinal direction in at least one region of the side of the fixing ring 200, is deformed by the applied stress to the circumference of the fixing ring 200 It may include an incision line 250 configured to increase. Here, the specific shape of the incision line 250 is shown in detail in FIG. 3 , and thus, reference will be made thereto.

3 is a front view of each of the fixing rings 200 in which various types of cut lines 250 are formed according to an embodiment of the present invention.

As shown in FIGS. 2 and 3 , the cut line 250 according to an embodiment of the present invention may be provided with a narrow gap in the longitudinal direction on the side surface of the fixing ring 200 . When the user first rotates the container opening and closing cap 10 to open the container, the container opening and closing cap 10 may rise little by little while rotating along the screw thread. In addition, as the container opening and closing cap 10 rises, stress may act on the locking jaw 210 of the fixing ring 200 that is caught by the fixing jaw and the movement is restricted. The cut line 250 is twisted by the applied stress and induces deformation of the upper and lower ends thereof, and thus the circumferential length of the fixing ring 200 may increase. Here, the fixing ring 200 may include a deformable portion 220 that is formed to surround the cut line 250 and is deformed by the applied stress to increase the circumference of the fixing ring 200 . That is, as shown in FIG. 3 , the portion in which the incision line 250 is deformed and increases in length corresponds to the deformable portion 220 as the incision line 250 is twisted.

At this time, as shown in (a) to (c) of FIG. 3 , when the cut-out line 250 is enlarged, the cut-out line 250 may have a narrow gap in the form of a column.

More specifically, the cut line 250 may be formed so that both ends of the cut line 250 have horizontal cut edges 251, respectively, as shown in FIG. 3A . That is, the gap constituting the cut line 250 may have a vertically long rectangular shape. In addition, the incision line 250 may be formed so that both ends of the incision line 250 have outwardly convex incision edges 251, respectively, as shown in FIG. 3(b), and in FIG. 3(c) and Similarly, the curved cut edge 251 may be formed to protrude to have a wider width than the horizontal width of the cut line 250 .

When a stress is applied to the incision line 250 , each of the incision edges 251 provided on the upper and lower portions of the incision line 250 receives forces in different directions, and thus the incision edge 251 becomes horizontal. It can be twisted in the direction to cause tensile deformation. And when the cut edge 251 is twisted and tensioned, the deformation part 220 may also be deformed in the transverse direction to increase the circumferential length of the fixing ring 200 by at least a partial length.

Here, the deformable portion 220 may be formed so that at least one surface in at least a partial region of the side of the fixing ring 200 has a thinner thickness than the other regions of the fixing ring 200 , and the cut-off line 251 is the deformable portion It may be located in the center of 220 .

For reference, the cut line 250 having a horizontal or curved cut edge 251 as shown in (a) to (c) of FIG. 3 may not be excessively deformed even if a stress is repeatedly applied. . That is, the horizontal or curved incision edge 251 only induces both ends of the incision line 250 to be stretched in the horizontal direction, and it is possible to prevent the fixing ring 200 from breaking due to the continuous gap in the vertical direction. have.

On the other hand, the shapes of the cut-off line 250 and the cut-off edge 251 shown in FIG. 3 are merely exemplary, and may be formed in more various shapes as long as the breakage of the fixing ring 200 can be prevented.

According to another embodiment of the present invention, as shown in (d) of FIG. 3 , circular cut-out holes 252 may be formed at both ends of the cut-out line 250 , respectively. The circular cut-out hole 252 may prevent excessive deformation of the cut-out line 250 similarly to the case in which the above-described horizontal or curved cut edge 251 is formed. That is, the position and size at which the incision hole 252 is formed is adjusted as needed and manufactured, so that the fixing ring 200 is not broken even by the repeated opening of the cap 10 for opening and closing the container. can be adjusted.

On the other hand, the position and size of the cut-off hole 252 shown in (d) of FIG. 3 is merely exemplary, and can be formed in more various positions and sizes as long as the breakage of the fixing ring 200 can be prevented. have.

Additionally, a plurality of incision lines 250 may be provided in the fixing ring 200 . And the angle formed by the plurality of incision lines 250 with respect to the center of the fixing ring 200 may vary. For example, when the fixing ring 200 is provided with two incisions 250 , both incisions 250 may be arranged to form an angle of 120°, 150°, 180°, or the like.

In addition, as shown in (e) and (f) of Figure 3, the length and arrangement of the cut line 250 with respect to the height of the fixing ring 200 can be implemented in various ways, and (g) and ( As shown in h), the incision line 250 may be formed in the longitudinal direction to be inclined at a predetermined angle with respect to the fixing ring 200 .

As described above, the fixing ring 200 can be manufactured by varying the number, angle, and shape of the incision edge 251 of the incision line 250 , and a deformable part surrounding the incision line 250 according to each factor. The degree of deformation of 220 may vary. For reference, the inventors of the present invention conducted an experiment to open the container opening and closing cap 10 by varying the number, angle, and shape of the incision edge 251 of the incision line 250, and the results are as follows: Table 1].

'Connection tip breakage (residual)' described in [Table 1] indicates the number of connection tips that are broken when the container opening and closing cap 10 is opened for the first time, and the number of connection tips that remain without breaking. That is, the connection part 300 of the container opening/closing cap 10, which is the subject of the experiment, initially included 12 connection tips 310, respectively, and as shown in [Table 1], the presence and absence of the incision line 250 and Depending on the number, the angle formed by the two incision lines 250 , and the shape of the incision edge 251 , a different number of connection tips 310 were broken.

In addition, it can be seen that the degree of increase in the length of the deformable portion 220 surrounding the incision line 250 due to plastic deformation according to each factor is different from each other. That is, as the length of the deformable portion 220 increases, some of the 12 connection tips 310 that were initially provided may not be broken, and the fixing ring 200 is formed by some remaining of the connection tips 310 . It can be taken out from the container body integrally with the main body 100 .

By increasing the circumference of the fixing ring 200 by the applied stress, the means for preventing the locking jaw 210 from being caught on the fixing jaw formed in the container body may include a deformation inducing part 221 and a shielding film 260 . Since the shape in which the deformation inducing part 221 and the shielding film 260 are provided in the fixing ring 200 is shown in FIG. 4 , it will be described with reference to this.

The deformation inducing part 221 according to an embodiment of the present invention may be provided in the form of a hole to pass through at least a portion of the side surface of the fixing ring 200 .

Meanwhile, although only a state in which one deformation inducing part 221 is formed is shown in the drawings, a plurality of deformation inducing parts 221 may be provided on the side surface of the fixing ring 200 . At this time, the circumferential length of the fixing ring 200 increased according to the arrangement relationship of the plurality of deformation inducing parts 221 (eg, the number of the deformation inducing parts 221 and the angle with respect to the center of the fixing ring 200) is different can do.

In addition, although the drawing illustrates that the deformation inducing part 221 is formed in a circular shape, the deformation inducing part 221 according to an embodiment of the present invention may be provided in the form of a rectangle, an ellipse, a rhombus, or a polygon. That is, the specific shape of the deformation inducing part 221 may vary.

The shielding film 260 according to an embodiment of the present invention may be configured to shield the hole of the deformation inducing part 221 as shown in FIG. 4A . Here, the specific shape of the shielding film 260 may be changed to a circle, a rectangle, an oval, etc. depending on the shape of the deformation inducing part 221 , and the thickness of the shielding film 260 may be variously adjusted as needed.

As described above, according to an embodiment of the present invention, by adding the configuration of the shielding film 260 , it is possible to prevent foreign substances, bacteria, etc. from penetrating into the inner space of the fixing ring 200 through the hole of the deformation inducing part 221 . . That is, even if the user repeatedly opens and closes the container opening and closing cap 10, it is possible to preserve the hygiene state of the product.

When stress is applied to the fixing ring 200 on which the deformation inducing part 221 and the shielding film 260 are formed as shown in FIG. The circumferential length of may be increased. More specifically, when the user first rotates the container opening and closing cap 10 to open the container, the container opening and closing cap 10 may rise little by little while rotating along the screw thread. In addition, as the container opening and closing cap 10 rises, stress may act on the locking jaw 210 of the fixing ring 200 that is caught by the fixing jaw and the movement is restricted. The width of the hole and the shielding film 260 of the deformation inducing part 221 may be increased left and right by the applied stress, and thus the circumferential length of the fixing ring 200 may be increased.

A method in which the circumferential length of the fixing ring 200 is increased by the deformation of the deformation inducing part 221 is as follows. First, when the container opening/closing cap 10 rotates and rises along the thread formed at the top of the container, the deformable portion 220 formed to surround the hole-shaped deformation inducing portion 221 is subjected to stress according to the tension, respectively. can Then, the band-shaped deformable portion 220 located on the upper and lower portions of the deformation inducing portion 221 may be stretched in the horizontal direction while being thinned by stress. That is, the deformation portion 220 formed on the upper and lower portions of the deformation inducing portion 221 may be plastically deformed to increase the length.

Here, plastic deformation can be viewed as a concept distinct from elastic deformation. That is, elastic deformation means that when a force is applied to an object, the shape is deformed, and when the force is removed, it returns to its original shape. On the other hand, plastic deformation has the meaning of permanent deformation in which a shape is deformed when a force is applied to an object, and the deformed shape is maintained even when the force is removed.

Accordingly, when the user rotates the container opening/closing cap 10 to open the container for the first time, stress is also applied to the deformation inducing part 221 , and at this time, the deformation part 220 located at the upper and lower portions of the deformation inducing part 221 is After the length is increased by each stress, it may not return to the original thickness and length. That is, after the user first rotates the cap 10 for opening and closing the container, the circumference of the fixing ring 200 according to an embodiment of the present invention can be maintained in an increased state.

Therefore, since plastic deformation, not elastic deformation, occurs in the deformable portion 220 according to an embodiment of the present invention, after the container opening and closing cap 10 is opened once, the action between the engaging jaw 210 and the fixed jaw Despite this, the fixing ring 200 can be easily coupled to or separated from the container body.

In addition, the deformable portion 220 positioned above and below the deformation inducing portion 221 may not be fractured even if the thickness thereof is reduced due to plastic deformation. Specifically, when stress due to tension acts on the cap 10 for opening and closing the container, the polymer chains constituting the deformable portion 220 may be moved and rearranged to form a polymer structure having a thinner and longer shape than before deformation. . The plastic deformation process in which these polymer chains are rearranged is called 'necking'.

In addition, 'crystallization' is induced in the polymer chains in which the neck deformation has occurred, so that the strength of the polymer structure may be increased. Crystallization refers to a process in which polymer chains are arranged in a certain direction to form a regular structure.

In summary, the stress is concentrated in the thin band-shaped deformation portion 220 constituting the upper and lower portions of the deformation inducing portion 221 to cause neck deformation, and then when the strength is increased by crystallization, it is not broken despite the reduced thickness be able to maintain

Similarly, the shielding film 260 configured to shield the deformation inducing part 221 may also increase the circumferential length of the fixing ring 200 by deformation. That is, when the container opening/closing cap 10 rotates and rises along the thread formed on the upper portion of the container, the shielding membrane 260 may receive stress due to tension. Then, the shielding film 260 may extend in the transverse direction as the thickness decreases, and may maintain a state in which the transverse length is increased by such plastic deformation. When the horizontal length of the shielding film 260 is increased by at least a partial length, the circumferential length of the fixing ring 200 may also be increased by that much.

On the other hand, as described above, the thickness of the shielding film 260 may be variously adjusted as needed, but is preferably formed to have a thinner thickness than other regions of the fixing ring 200 . That is, since the thickness of the shielding film 260 is formed to be thinner than that of other regions of the fixing ring 200 , the stress acting on the fixing ring 200 may be concentrated to stretch the shielding film 260 in the horizontal direction. At this time, like the deformable part 220 , the polymer chains constituting the shielding film 260 may be moved and rearranged to form a polymer structure having a thinner and longer shape than before deformation by stress. And, 'crystallization' is induced in the polymer chains, so that the strength of the polymer structure may be increased.

In addition, a position where the shielding film 260 shields the hole of the deformation inducing part 221 may be varied. That is, the shielding film 260 is formed in any one of the inner surface part, the outer surface part, and the central part of the fixing ring 200 with respect to the hole of the deformation inducing part 221, so that the hole passing through the fixing ring 200 can be shielded. .

In addition, as shown in (b) of FIG. 4 , in the fixing ring 200 , along with the deformation inducing part 221 and the garimmak 260 , a cut line 250 is further formed in the center of the garimmak 260 in the longitudinal direction. can be formed. Since the function according to the configuration of the incision line 250 is the same as described above, overlapping descriptions will be omitted in this paragraph.

Additionally, a plurality of deformation inducing parts 221 may be provided in the fixing ring 200 . And the angle formed by the plurality of deformation inducing parts 221 with respect to the center of the fixing ring 200 may be varied. For example, when two deformation inducing parts 221 are provided in the fixing ring 200, both deformation inducing parts 221 may be disposed to form an angle of 150°, 180°, or the like.

As described above, the fixing ring 200 can be manufactured by varying the presence or absence of the shielding film 260 and the number and angle of the deformation inducing parts 221 , and the degree of deformation of the deformable part 220 varies according to each factor. can For reference, the inventor of the present invention conducted an experiment to open the container opening and closing cap 10 by varying the presence or absence of the shielding film 260, the number and angle of the deformation inducing part 221, and the results are shown in the following [Table]. 2].

The 'connection tip breakage (residual)' described in [Table 2] indicates the number of connection tips that are broken when the container opening/closing cap 10 is opened for the first time and the number of connection tips that remain without breaking. That is, as in [Table 1], the connection part 300 of the cap 10 for opening and closing the container to be tested initially included 12 connection tips 310, respectively, and was deformed as shown in [Table 2]. A different number of connection tips 310 were broken depending on the presence and absence of the induction part 221 , the number, and the presence or absence of the shielding film 260 . And referring to the last row of [Table 2], it can be seen that when the cut-out line 250 is additionally provided in the shielding film 260, a larger number of connection tips 310 remain than in the case where the incision line 250 is not provided. .

In addition, it can be seen that the degree of increase in the length of the deformable portion 220 formed on the upper and lower portions of the deformation inducing portion 221 due to plastic deformation according to each factor is different from each other. That is, as the length of the deformable portion 220 increases, some of the 12 connection tips 310 that were initially provided may not be broken, and the fixing ring 200 is formed by some remaining of the connection tips 310 . It can be taken out from the container body integrally with the main body 100 .

For reference, when the shielding film 260 and the cut-off line 250 are provided on the fixing ring 200 at the same time as shown in FIG. 4(b), the fixing ring ( 200) may increase the effect of increasing the circumferential length. Therefore, even if the thickness of the shielding film 260 is formed thicker than in the case where the incision line 250 is not provided, the circumferential length of the fixing ring 200 can be easily increased by the operation of the user opening the cap 10 for opening and closing the container. can be increased.

In addition, even when the shielding film 260 and the incision line 250 are provided at the same time, it goes without saying that the specific shape of the incision line 250 may be variously formed as shown in FIGS. .

As described above, the circumference of the fixing ring 200 may be increased by the configuration of the deformation inducing part 221 , the shielding film 260 and/or the incision line 250 provided in the fixing ring 200 . And, when the circumference of the fixing ring 200 is increased, at least some of the plurality of connection tips 310 of the connection part 300 according to an embodiment of the present invention may not be broken. That is, since the breaking of the connection tip 310 is due to the action of the locking jaw 210 caught on the fixing jaw, the connection tip 310 is broken when the area caught on the fixing jaw decreases due to the increase in the circumference of the fixing ring 200 . The number of may also be reduced.

Accordingly, at least one of the plurality of connection tips 310 constituting the connection part 300 is not broken and the coupling is maintained, and the body 100 and the fixing ring 200 are combined while maintaining the state as a unitary container. can be separated from the body. That is, after the user rotates the cap 10 for opening and closing the container for the first time, the connection tip 310 may no longer be broken, and since then, the container body 100 and the fixing ring 200 are bound as an integral body. may be combined with or separated from

Figure 5 (a) is a perspective view of the fixing ring 200 in which a cut line 250 is formed in the deformable portion 220 having a thin thickness according to an embodiment of the present invention, Figure 5 (b) is the present invention It is a perspective view of the fixing ring 200 in which the shielding film 260 is formed on the deformable part 220 having a thin thickness according to an embodiment.

As shown in (a) and (b) of Figure 5, the deformable portion 220 according to an embodiment of the present invention in at least some area of the side of the fixing ring 200 than in other areas of the fixing ring 200 It may be formed to have a thinner thickness. Forming the deformable portion 220 to be thin may have the same effect as the forming of the deformation inducing portion 221 and the shielding film 260 in at least a partial region of the side surface of the fixing ring 200 as a result.

Specifically, when the container opening/closing cap 10 rotates and rises along the thread formed at the top of the container, the deformable portion 220 formed in a thin thickness may receive stress due to tension. Then, the deformable part 220 may be stretched in the horizontal direction as the thickness becomes thinner by the stress. That is, as stress according to tension is concentrated on the deformable portion 220 formed to have a thinner thickness than other regions of the fixing ring 200 , the deformable portion 220 may be plastically deformed to increase the length.

In addition, after the length of the deformable part 220 is increased by plastic deformation, it may not return to the original thickness and length. That is, after the user first rotates the cap 10 for opening and closing the container, the circumference of the fixing ring 200 according to an embodiment of the present invention can be maintained in an increased state.

According to a further embodiment of the present invention, as shown in Fig. 5 (a), the configuration of the cut-off line 250 is further added to the configuration of the deformable portion 220 that is formed to have a thinner thickness than other regions. can When a plurality of such components are formed at the same time in the fixing ring 200, the effect of increasing the circumferential length of the fixing ring 200 according to the applied stress than if each component is provided alone may be increased. In addition, even when the deformable part 220 and the incision line 250 are provided at the same time, the specific shape of the incision line 250 may be variously formed as shown in FIGS. am.

Additionally, as shown in (b) of FIG. 5, the configuration of the deformation inducing part 221 and the shielding film 260 may be further added to the configuration of the deformable part 220 that is formed to have a thinner thickness than other regions. , although not shown in the drawing, it is also possible to form the deformable part 220 , the deformation inducing part 221 , the shielding film 260 and the incision line 250 to include all of the configurations. That is, it will be possible to freely combine each configuration according to the conditions of the technological level, equipment, environment, etc. for manufacturing the cap 10 for opening and closing the container. In addition, at this time, the deformable portion 220 may be configured to increase the circumference of the fixing ring 200 by the applied stress in succession with the deformation inducing portion 221 .

On the other hand, when the configuration of the deformable portion 220, the deformation inducing portion 221, and the shielding film 260 having a thin thickness are formed together in the fixing ring 200, the shielding film 260 fills the hole of the deformation inducing portion 221. The shielding position may vary. That is, the shielding film 260 is formed in any one of the inner surface portion, the outer surface portion, and the central portion of the fixing ring 200 with respect to the hole of the deformation inducing portion 221 as described above in FIG. 4 , thereby penetrating the fixing ring 200 . hole can be blocked. Also, in addition to shielding the hole of the deformation inducing unit 221 , the shielding film 260 may be additionally provided on one side of the deformable unit 220 in the form of a film.

6 illustrates a state in which the folded deformable portion 220 is unfolded by stress according to an embodiment of the present invention.

As shown in FIG. 6 , the deformable part 220 according to an embodiment of the present invention may be provided to have a folded shape. That is, in the state before the user opens the container for the first time, the deformable part 220 is folded as if bent in a curve as shown in the left figure in FIG. It may be folded in such a way that it is folded with .

Then, when the user rotates the container opening and closing cap 10 to open the container, the container opening and closing cap 10 may rise little by little while rotating along the screw thread. In addition, as the container opening and closing cap 10 rises, stress may act on the locking jaw 210 of the fixing ring 200 that is caught by the fixing jaw and the movement is restricted. Then, the folded deformable portion 220 may be unfolded in the horizontal direction as shown in the right figure of FIG. 6 , and thus the circumferential length of the fixing ring 200 may increase.

For reference, although not shown in the drawings, the configuration of the deformation inducing portion 221 , the shielding film 260 and the cut-out line 250 as described above may be optionally further added to the folded deformation portion 220 . do. In addition, even when a plurality of components are provided at the same time, the specific shape of the cut line 250 may be variously formed as shown in FIGS. 3A to 3H .

Although not shown in the drawings, the fixing ring 200 according to another embodiment of the present invention has at least one surface thinner than the thickness of the fixing ring 200, and the stress required for deformation is lower than that of the fixing ring 200, the container When the opening/closing cap 10 is opened, the plurality of connection tips 310 may include a deformable portion 220 in which plastic deformation occurs to increase the circumference of the fixing ring 200 before all cuttings. In addition, the fixing ring 200, a part of the fixing ring 200 is removed, the elongation rate is higher than that of the deformable portion 220 at the same stress, and an open portion (not shown) formed continuously with the deformable portion 220 is further added. may include

Accordingly, even if the fixing ring 200 according to the present invention is not provided with the hole-shaped deformation inducing part 221 , only the thickness of the deformable part 220 formed in one region of the fixing ring 200 is adjusted by the fixing ring 200 . ) can be increased. That is, the circumference of the fixing ring 200 may be increased by plastic deformation occurring in the deformable portion 220 that is formed thinner than other regions of the fixing ring 200 .

In addition, the fixing ring 200 according to an embodiment of the present invention may be characterized in that the diameter of the lower portion of the fixing ring 200 is larger than the upper portion. That is, the diameter of the fixing ring 200 may be formed in a shape that gradually increases from the top to the bottom. According to an embodiment of the present invention, when the circumference of the fixing ring 200 increases when the container opening and closing cap 10 is first opened, thereafter, the body 100 and the fixing ring 200 are repeated from the container body as one body. can be opened and closed. At this time, since the diameter of the lower part of the fixing ring 200 is formed to be larger than that of the upper part, the cap 10 for opening and closing the container including the fixing ring 200 can be more easily drawn into and coupled to the inlet of the container body.

As described above, according to the container opening and closing cap according to an embodiment of the present invention, when the user first rotates the cap to open it, the circumference of the fixing ring is increased by the deformation inducing part in the form of an incision or hole formed in the fixing ring. As a result, the fixing ring can be easily separated without being caught on the fixing jaws of the container inlet.
