Description

One-touch cover and packaging container including the same

The present invention relates to a one-touch cover and a packaging container including the same.

A water tissue is made by thinly structuring synthetic fibers, viscose fibers, cotton fibers, cellulose fibers, and natural vegetable fibers, and then adding water thereto and sterilizing them.

Wet tissues are stored and sold in containers such as plastic bags to prevent moisture evaporation and facilitate portability.

Referring to FIGS. 16 and 17, the container holds the water tissue as the content therein, and is attached to one side of the container body (1) having a withdrawal hole (1a) for taking out the wet tissue, and the container body (1). and a cover 2 for opening and closing the withdrawal hole 1a.

The cover 2 is attached to one surface of the container body 1 and is coupled to the base 21 and the base 21 having an opening hole 21a connected to the withdrawal hole 1a to open and close the opening hole 21a. The cover body 22, the base 21 and the locking part 23 for maintaining the closed state of the cover body 22 on one side of the base 21 and the cover body 22, and the base 21 and the cover body 22 are connected from the other side and a hinge part 24 that is doing it.

In a state in which the base 21 and the cover body 22 are coupled, the hinge part 24 is folded and an elastic force is generated (see FIG. 17 a). When the locking part 23 is unlocked, the cover body 22 is rotated with respect to the hinge part 24 by the elastic force of the hinge part 24 to completely open the opening hole 21a (FIG. 17b). Reference).

On the other hand, a fold line 24a is formed on the hinge part 24 . The fold line 24a is formed by removing a portion of the hinge portion 24 . The hinge portion on which the fold line 24a is formed is thinner than the hinge portion on which the fold line 24a is not formed. As the strength of the fold line 24a was weakened due to repeated rotation of the cover body 22, a phenomenon in which the elastic force was lowered occurred. Accordingly, when the locking part 23 is unlocked, the cover body 22 is not opened, so the user has to directly open the cover body 22 .

The present invention provides a technique for increasing the openness of the cover body by improving the hinge portion connecting the base and the cover body of the one-touch cover coupled to the container body.

The one-touch cover according to an embodiment of the present invention includes a base having an upper and lower penetrating opening hole formed therein, a cover body connected to the base to open and close the opening hole, and a hinge part connecting the cover body and the base.

When the cover body closes the opening hole, a portion of the hinge portion is bent to form a curvature having a predetermined diameter.

The hinge unit may include a pedestal formed on the base, a main hinge connected to the pedestal, a presser connected to the main hinge, and at least one auxiliary hinge connecting the presser and the cover body.

The main hinge, which is bent when the cover body closes the opening hole, may not be bent any more while the support and the presser come into contact with each other.

At least one bending groove is formed in the auxiliary hinge along the longitudinal direction, and when the pedestal and the presser come into contact with each other, the bending groove forming portion of the auxiliary hinge may be bent.

The hinge part may further include a plurality of emboss formed on the main hinge.

An area ratio of the main hinge and the emboss may be 1:0.07 to 0.09.

Guide grooves may be formed in both sides of the main hinge in an inward direction, and a depth dimension of the guide groove may be smaller than a width dimension of the main hinge.

The guide groove may be an arc.

An area ratio of the main hinge and the auxiliary hinge may be 1:0.6 to 0.8.

A thickness ratio of the auxiliary hinge and the main hinge may be 1:0.6 to 1.

The pedestal has an inclined surface protruding from the base and in contact with the presser, and the inclined surface may form an angle of 5° to 30° with the horizontal center of the curvature.

A protrusion in contact with the inclined surface may be formed on the presser.

The length ratio of the cover body and the auxiliary hinge may be 1:0.6 to 0.8, and the length ratio between the cover body and the main hinge may be 1:0.4 to 0.6.

The curvature forms a semicircle, and the diameter of the semicircle may be 2 mm to 4 mm.

The curvature forms an ellipse, and a length ratio of a major axis and a minor axis of the ellipse may be 1:0.5 to 0.7.

The one-touch cover may further include a position limiting portion formed at one end in the width direction of the hinge portion connected to the base, and an anti-slip portion formed at the other end in the width direction of the hinge portion connected to the cover body.

When the hinge part is bent, the bending preventing part is caught in the position limiting part, and the bending of the hinge part and the position of the cover body may be limited.

The unfolded hinge portion is convex in an outward direction and has a curvature of 21 mm to 24 mm, and the curvature may guide the hinge portion to be bent in a curved shape when the hinge portion is bent.

The position limiter may include a pedestal protruding upward between the hinge part and the base and having an inclined surface, and a limiting jaw protruding upward from one side of the inclined surface.

The tilt prevention part protrudes upward from the other end of the hinge part, and one side is connected to the inner surface of the hinge part, and the upper surface of the tilt prevention part due to the bending of the hinge part is in contact with the inclined surface, and the other side of the tilt prevention part is While in contact with the limiting jaw, the tilt-preventing part may not deviate from the position limiting part.

The one-touch cover may further include an auxiliary hinge connecting the other end of the hinge part and the cover body.

A bending groove may be formed on the inner surface of the auxiliary hinge, and a plurality of the bending grooves may be formed at intervals along the width direction of the auxiliary hinge.

A thickness (t1) of one end of the auxiliary hinge in which the first bending groove is formed may be thinner than the thickness (t2) of the other end of the auxiliary hinge in which the second bending groove is formed, and the hinge is bent for coupling the cover body and the base. When the first bending groove and the second bending groove are formed, the auxiliary hinge may be bent step by step from a thin portion.

The unfolded hinge portion may be formed to be convex with a curvature in an outward direction, and the auxiliary hinge may be formed to have a curvature and convex inward direction in a direction opposite to the hinge portion.

A width direction area ratio of the hinge part and the auxiliary hinge may be 1:0.6 to 0.7.

A length 262L of the limiting jaw protruding from the pedestal may be 0.5 mm to 1.5 mm, a thickness 262t of the limiting jaw may be 0.6 mm to 1 mm, and a length of the limiting jaw may be 4.5 mm to 5.5 mm.

The limiting jaw may be formed with two to four intervals along the longitudinal direction of the pedestal.

The packaging container according to an embodiment of the present invention has the one-touch cover described above, and the contents can be contained therein, and a withdrawal hole for withdrawing the contents is formed on one side, and the one-touch cover is disposed on the one side, Includes a container body with

According to an embodiment of the present invention, when the cover body is in contact with the base, the main hinge is bent to form a circle. When the protrusion comes into contact with the pedestal, the main hinge does not bend any more and maintains a circular state. The main hinge forms a curvature and does not bend or fold to prevent damage and deformation. This maximizes the lifespan of the main hinge and improves the service life of the contents.

According to an embodiment of the present invention, elastic force is generated as the auxiliary hinge is bent stepwise by the inclined surface of the pedestal. Accordingly, when the lock is released by the elastic force of the auxiliary hinge and the elastic force of the main hinge, the cover body can be rotated quickly based on the hinge part.

According to an embodiment of the present invention, the upper surface of the anti-slip portion due to the bending of the hinge portion is caught on the limiting jaw while in contact with the inclined surface of the pedestal. Accordingly, the position of the cover body is limited and the hinge part is not bent in the direction of the lock part, and thus the hinge part can be maintained in a curved state as it is.

According to an embodiment of the present invention, when the tilt-preventing part is in contact with the pedestal, the auxiliary hinge is bent stepwise and elastic force is generated. Accordingly, when the lock is released by the elastic force of the auxiliary hinge and the elastic force of the hinge part, the cover body can be rotated quickly based on the hinge part.

According to an embodiment of the present invention, since the auxiliary hinge is bent with a curvature in the opposite direction to the hinge portion, the elastic force to return to the original state when the cover body is opened is improved, so that the openability of the cover body is excellent.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those of ordinary skill in the art to which the present invention pertains can easily carry out the present invention. However, the present invention may be embodied in several different forms and is not limited to the embodiments described herein. Throughout the specification, like reference numerals are assigned to similar parts.

The one-touch cover according to an embodiment of the present invention can be applied to a packaging container according to an embodiment of the present invention, and hereinafter, the packaging container to which the one-touch cover is applied will be mainly described.

Then, a packaging container according to an embodiment of the present invention will be described with reference to FIGS. 1 to 7 .

1 is a schematic view showing a state in which the one-touch cover is combined with a container according to an embodiment of the present invention, FIG. 2 is a schematic view showing an open state of the cover body of FIG. 1, and FIG. 3 is an enlarged view of part A of FIG. 4 is a plan view showing the one-touch cover of FIG. 2 , FIG. 5 is a cross-sectional view taken along the line V-V in FIG. 4 , FIG. 6 is an enlarged view of part B of FIG. 5 , and FIG. 7 is the cover body of FIG. It is an operation diagram showing the state of closing the open hole of the base.

First, referring to FIGS. 1 and 2 , the packaging container according to the present embodiment is a one-touch cover 100 . And it includes a container body (1). The one-touch cover 100 includes a base 110 , a cover body 120 , and a hinge part 140 , and improves the hinge part 140 to increase the openness of the cover body 120 .

The contents can be stored inside the container body 1, and a withdrawal hole 1a through which the contents can be drawn out is formed on one surface. An adhesive sheet (not shown) for fixing the one-touch cover 100 is disposed around the draw-out hole 1a. The container body 1 may be made of resin. However, the container body 1 may be made of plastic. The material of the container body 1 may vary depending on the type of contents. The content may be a wet tissue. However, the contents may be food, edible food such as medicines, and household items such as plastic and tissue. The type of contents contained in the container body 1 is not specifically limited.

An open hole 110a penetrating in the vertical direction is formed inside the base 110 . A seating groove 110b is formed along the periphery of the open hole 110a on the upper surface of the base 110 . The lower surface of the base 110 is coupled to the container body 1 containing the contents. At this time, the lead-out hole 1a of the container body 1 and the open hole 110a communicate with each other.

The cover body 120 may open and close the opening hole 110a in the upper surface of the base 110 . The edge of the cover body 120 is located in the seating groove (110b). A protrusion is formed in the edge of the cover body 120 and the seating groove 110b. The protruding jaw of the cover body 120 is in contact with the seating groove 110b, and the protruding jaw of the seating groove 110b is in contact with the cover body 120 to maintain the airtightness of the opening hole 110a.

The cover body 120 is connected to the base 110 through the hinge unit 140 . The cover body 120 may rotate with respect to the hinge unit 140 . The cover body 120 and the base 110 are bound by a locking part 130 so that the cover body 120 seated on the base 110 does not rotate.

The locking unit 130 is disposed at the front end of the cover body 120 and the base 110 , and the hinge unit 140 is disposed at the rear end of the cover body 120 and the base 110 . The locking part 130 includes a locking protrusion 131 formed on the tip of the cover body 120 and a button 132 disposed on the tip of the base 110 and having a locking groove (not shown) formed thereon.

When the locking jaw 131 is caught in the locking groove, the cover body 120 and the base 110 are bound, so that the cover body 120 can close the opening hole 110a. In this case, an elastic force may be generated in the hinge unit 140 . When the tip of the button 132 is pressed, the locking jaw 131 may escape the locking groove. The cover body 120 is rotated by the elastic force of the hinge part 140 to be separated from the base 110 and the opening hole 110a is opened to expose the contents of the container body 1 . The rotating cover body 120 may be opened at an angle of 35° to 130° with respect to the upper surface of the base 110 by the elastic force of the hinge unit 140 .

Meanwhile, the weight of the base 110 may be 5.00 g to 6.00 g. A preferred weight of the base 110 may be 5.65 g. The weight of the cover body 120 may be 5.00 g to 6.00 g. A preferred weight of the cover body 120 may be 5.40 g. The weight of the cover body 120 may be less than the weight of the base 110 . And the thickness of the cover body 120 may be 0.8 mm to 1.2 mm. When the thickness is less than 0.8 mm, a problem may occur that the cover body 120 is easily bent by an external force, and if the thickness exceeds 1 mm, the weight of the cover body 120 increases and the opening is not easily made.

3 to 6 , the hinge unit 140 includes a pedestal 141 , a main hinge 142 , a presser 144 , and an auxiliary hinge 145 .

The pedestal 141 protrudes upward from the rear end of the base 110 . The pedestal 141 has a progressively smaller cross-sectional area from the surface of the base 110 to the top. The upper surface of the pedestal 141 is formed as an inclined surface 141a. The inclined surface 141a is inclined in the form of rising from the rear of the base 110 to the front, and the inclined surface 141a forms an acute angle with a virtual horizontal line L parallel to the lower surface 110d of the base 110, and the The angle D may be 5° to 30°. When the angle D is formed to be less than 5°, the elastic force applied to the hinge unit 140 is insufficient, so that the cover body 120 does not open at an angle of 35° to 130° with respect to the upper surface of the base 110 . When the angle (D) exceeds 30°, the outer surface of the hinge unit 140 may be deformed in a protruding form, thereby deteriorating the appearance. In addition, the locking jaw 131 may not be caught in the locking groove, and the outer appearance of the cover body 120 may be convex in order for the locking jaw 131 to be caught in the locking groove. Accordingly, the overall appearance of the one-touch cover 100 may be deteriorated.

The main hinge 142 protrudes from the rear end of the base 110 . At this time, the upper and lower surfaces of the main hinge 142 form a curve, respectively. The main hinge 142 forms a predetermined angle with the virtual horizontal line L. However, the main hinge 142 may be parallel to the virtual horizontal line L. The main hinge 142 may be bent by an external force. In this case, the main hinge 142 may be formed to have a curvature having a predetermined diameter. The length of the main hinge 142 is shorter than the length of the base 110 and the cover body 120 . The length ratio of the cover body 120 and the main hinge 142 may be 1:0.4 to 0.6. When the length ratio is formed to be less than 1:0.4, the cover body 120 cannot be rotated because it cannot support the cover body 120 having a weight of 5.40 g. Accordingly, the opening of the cover body 120 is reduced.

The planar area of the main hinge 142 may be 200 mm 2 to 220 mm 2 and the thickness may be 0.3 mm to 0.4 mm.

When the thickness of the main hinge 142 is formed to be less than 0.3 mm, the cover body 120 has the advantage of easy bending when closing the opening hole 110a, but the elastic force generated for opening the cover body 120 is insufficient. Therefore, the opening of the cover body 120 is not easy. In addition, the lifespan of the main hinge 142 in which repetitive bending occurs may be shortened. When the thickness of the main hinge 142 is formed to exceed 0.4 mm, it is not easy to bend the main hinge 142 due to an increase in thickness.

On both sides of the main hinge 142 in the longitudinal direction, guide grooves 142a recessed in the inward direction are formed. The guide groove 142a is formed in a semicircle. However, the guide groove 142a may be formed at an acute angle with respect to the center of the width direction of the main hinge 142 as the thickness of the main hinge 142 increases. At this time, the circumference of the guide groove 142a is formed in a straight line, and the cross-sectional area becomes narrower toward the inside from the longitudinal end of the main hinge 142 . A depth dimension of the guide groove 142a is smaller than a width dimension of the main hinge 142 . The guide groove 142a becomes a standard for bending when the main hinge 152 is bent to form a circle, so that the main hinge 152 is eccentric on one side and can be bent in a semicircular shape without being crushed.

Emboss 143 are formed on the outer surface of the main hinge 142 . The embossed 143 protrude in the form of circular protrusions. The protrusion length of the embossing 143 does not exceed 20% to 40% of the thickness of the main hinge 142 . The embossing 143 is arranged along the width direction and the length direction of the main hinge 142 . The circular diameter of the embossing 143 may be 0.5 mm to 0.7 mm. The area ratio of the main hinge 142 and the embossed 143 when viewed in a plane may be 1: 0.4 to 0.6. When the area ratio of the main hinge 142 and the embossing 143 is less than 1: 0.4, the effect of the embossing 143 is insignificant and there is no embossing 143 effect, and the area ratio of the main hinge 142 and the embossing 143 is 1: When it exceeds 0.6, the bending of the main hinge 142 is not easy due to an increase in the thickness of the main hinge 142 .

The embossing 143 pulls the outer surface of the main hinge 142 when the main hinge 142 is bent, thereby preventing the main hinge 142 from being bent or deformed in a folded form. The embossing 143 forms a curvature shape when the main hinge 142 is bent.

Meanwhile, the embossing 143 may also be formed on the inner surface of the main hinge 142 . At this time, the embossing 143 may be formed in a recessed shape. The structure of the embossing 143 may vary depending on the design of the hinge unit 140 .

The presser 144 is connected to the main hinge 142 that is farthest from the base 110 . The press bar 144 is formed along the longitudinal direction of the main hinge 142 , and the length of the press bar 144 is longer than the length of the main hinge 142 and shorter than the length of the cover body 120 .

A protrusion 144a is formed at a portion of the presser 144 connected to the main hinge 142 . The protrusion 144a is formed along the longitudinal direction of the main hinge 142 . When the main hinge 142 is parallel to the imaginary horizontal line L, the presser 144 is formed to protrude upward from the main hinge 142 . And the presser 144 is inclined downward in the protruding state. However, the pressing bar 144 may not form an inclination. The protrusion 144a may come into contact with the inclined surface 141a when the main hinge 142 is bent in a curvature shape.

The auxiliary hinge 145 connects the press bar 144 and the cover body 120 . The length of the auxiliary hinge 145 is longer than the length of the main hinge 142 and shorter than the length of the cover body 120 . The length ratio of the cover body 120 and the auxiliary hinge 145 may be 1:0.6 to 0.8. The thickness of the auxiliary hinge 145 may be 0.4 mm to 0.5 mm. A thickness ratio of the auxiliary hinge 145 and the main hinge 142 may be 1:0.6 to 1.0. The area ratio of the main hinge 142 and the auxiliary hinge 145 may be 1:0.6 to 0.8. Since the main hinge 142 is thinner than the auxiliary hinge 145 , the main hinge 142 is bent to form a circular shape, and then the auxiliary hinge 145 is bent. If the main hinge 142 is thicker than the auxiliary hinge 145 , the auxiliary hinge 145 is bent before the main hinge 142 , so the main hinge 142 is not formed in a circular shape. And the cover body 120 is lifted without being in close contact with the base 110 . In addition, as the auxiliary hinge 145 is bent first, the outer surface of the auxiliary hinge 145 is bent in a protruding form, thereby impairing the appearance of the one-touch cover 100 .

A bending groove 145a is formed in the auxiliary hinge 145 in the longitudinal direction. A plurality of bending grooves 145a are formed at intervals along the width direction of the auxiliary hinge 145 . However, one bending groove 145a may be formed according to the width of the auxiliary hinge 145 . When the presser 144 is in contact with the inclined surface 141a, the auxiliary hinge 145 may be bent in multiple stages by the plurality of bending grooves 145a. The main hinge 142 bent in a curve due to the bending of the auxiliary hinge 145 in a state in which the presser 144 and the pedestal 141 are in contact may not be bent any longer. Accordingly, the main hinge 142 may not be bent or folded.

Next, the operation of the one-touch cover described above will be described.

In order to protect the contents contained in the container body 1, the cover body 120 is in contact with the base 110 and closes the opening hole 110a (see FIG. 1). At this time, the hinge portion 140 is bent to maintain the elastic force. When the user presses the button 132, the locking jaw 131 is released from the locking groove and the lock is released. The cover body 120 is rotated by the elastic force of the hinge unit 140 to separate from the base 110 . The cover body 120 is opened at an angle D of 30° to 130° with respect to the upper surface of the base 110 to open the opening hole 110a, and the upper and lower surfaces of the main hinge 142 are curved. The periphery of the extraction hole 1a is exposed and the contents can be drawn out (refer to FIG. 2 ).

The closing of the cover body 120 will be described with reference to FIG. 7 .

The user may rotate the open cover body 120 in the direction of the base 110 to close the opening hole 110a after taking out the contents. The thickness of the main hinge 142, which is thinner than the thickness of the auxiliary hinge 145, has a curved upper surface and a lower surface, and is formed in a circular shape while being bent based on the guide groove 142a. At this time, the emboss 143 reinforces the outer surface of the main hinge 142 so that the main hinge 142 is formed in a circular shape without being folded or bent. When the protrusion 144a comes into contact with the inclined surface 141a, the main hinge 142 is no longer bent. The main hinge 142 is formed in a circular shape of curvature having a predetermined diameter. The diameter (I) of the circle may be formed in a range of 2 mm to 4 mm. When the diameter (I) of the circle is formed to be less than 2 mm, the width of the main hinge 142 is short and the circle is well formed, but the cover body 120 is not lifted up because it cannot overcome the weight of the cover body 120 . When the diameter of the circle (I) exceeds 4 mm, since the diameter of the circle increases, the rotation range of the cover body 120 is increased (refer to FIG. 7 a).

An elastic force is generated in the circular main hinge 142 , and when the external force rotating the cover body 120 is removed, the circular main hinge 142 can return to its original state by the elastic force. However, although not formed in the drawings, the curvature of the main hinge 142 may be formed in an ellipse. In this case, the length ratio of the major axis and the minor axis of the ellipse may be 1:0.5 to 0.7.

On the other hand, by the angle of the inclined surface 141a, the front of the cover body 120 is in a state of being lifted from the front of the base 110, so that the locking jaw 131 (refer to FIG. 2) is not caught in the locking groove. When the user presses the front of the cover body 120 in the direction of the base 110, stress is generated in the portion of the protrusion 144a in contact with the inclined surface 141a. At this time, since the protrusion 144a is in contact with the inclined surface 141a, when the part of the auxiliary hinge 145 in which the bending groove 145a is formed is bent stepwise toward the bottom of the base 110, the locking jaw 131 may be caught in the locking groove. . When the cover body 120 is locked, the cover body 120 maintains a state in contact with the base 110 (see FIG. 7 b and c).

Accordingly, according to the present embodiment, when the cover body 120 is in contact with the base 110, the main hinge 142 is bent to form a circle. When the protrusion 144a is in contact with the pedestal 141, the main hinge 142 is no longer bent and maintains a circular state. The main hinge 142 is curved so that it is not bent or folded, thereby preventing damage and deformation. Accordingly, the lifespan of the main hinge 142 is maximized, and the moisture retention life of the contents containing moisture is also improved.

Such one-touch cover 100 is made of polypropylene (PP), low density polyethylene (LDPE), ethylene-vinyl acetate copolymer (EVA), elastomer, and combinations thereof. Any one selected from the group consisting of 70 to 80: 20 to 30 may include a weight ratio. When the polypropylene is formed in a weight ratio of less than 70, the weight ratio of LDPE, EVA, and elastomer increases, so that the elastic force of the hinge part may be reduced. In addition, when the polypropylene exceeds 80 weight ratio, the strength of the hinge portion is increased, and thus the polypropylene may be easily broken.

Next, a packaging container according to another embodiment of the present invention will be described with reference to FIGS. 8 to 15 .

First, referring to FIGS. 8 to 12 , the packaging container according to the present embodiment is a one-touch cover 200 . And it includes the container body (1) and increases the openness of the one-touch cover (200).

The configuration and operation of the container body 1 according to this embodiment is the same as that of the container body according to the embodiment of FIGS. 1 to 7 , and thus the duplicate description will be omitted.

The one-touch cover 200 is disposed around the draw-out hole 1a to protect the contents from external contamination sources such as dust, and includes a base 210, a cover body 230, a hinge part 250, a position limiting part 260 and It includes a tilt prevention unit 270 . The one-touch cover 200 may further include an auxiliary hinge 280 .

The base 210 is coupled to the upper surface of the container body 1 with an adhesive sheet. The edge of the base 210 is formed with an inclined surface, and the edge is formed with a curved surface.

The base 210 has an upper surface recessed to form a seating groove 212 . An open hole 211 connected to the withdrawal hole 1a is formed at the bottom of the seating groove 212 . The opening hole 211 is formed to penetrate through the base 210 vertically.

At one end of the base 210 in the width direction (Y), a locking portion 220 having a locking groove 221 is disposed. Although the periphery of the locking part 220 is spaced apart from the base 210 , a portion of the other end where the locking groove 221 is formed is connected to the base 210 . When an external force is applied to one end of the locking part 220 , it may be bent based on a portion connected to the base 210 .

The cover body 230 is connected to the other end in the width direction (Y) of the base 210 through the hinge part 250 and the auxiliary hinge 280 . The width of the cover body 230 is smaller than the width of the base 210 . The cover body 230 may be seated in the seating groove 212 while overlapping the base 210 as the hinge part 250 and the auxiliary hinge 280 are bent to close the opening hole 211 .

A portion of the other side of the cover body 230 seated in the seating groove 212 is in contact with the other side of the locking part 220 to face the portion in which the locking groove 221 is formed. The other part of the cover body 230 is inserted into the locking groove 221, the locking projection 240 is protruded. While the locking jaw 240 is caught in the locking groove 221 , the cover body 230 may be seated in the seating groove 212 to maintain a state in which the opening hole 211 is closed. However, when the locking part 220 is bent by an external force, the locking jaw 240 may deviate from the locking groove 221 . At this time, the cover body 230 is rotated away from the base 210 while falling from the seating groove 212 by the elastic force of the bent hinge part 250 and the auxiliary hinge 280 to open the opening hole 211. have.

One end of the hinge unit 250 is connected to the other end of the base 210 , and the other end is connected to one end of the cover body 230 through the auxiliary hinge 280 . The hinge part 250 is formed along the longitudinal direction of the base 210 and the cover body 230 . The length of the hinge part 250 is smaller than the length of the cover body 230 . Both ends of the hinge part 250 in the longitudinal direction (X) are concave in the inner direction in a semicircle shape. It is possible to guide the concave both ends of the hinge part 250 to be bent in a curved shape without being folded.

When the cover body 230 is unfolded from the base 210, the hinge part 250 is not spread flat but is formed as a convex curved surface from the inner surface to the outer surface, and has a curvature value D of 21 mm to 24 mm. A thickness 250t between the outer and inner surfaces of the hinge unit 250 may be 0.2 mm to 0.3 mm. A thickness 250t of the hinge part 250 may be 0.228 mm.

The curved surface guides the hinge part 250 to be bent in a curved shape without being bent (bent) when it is bent. Accordingly, when the cover body 230 is seated in the seating groove 212 , the hinge part 250 is not deformed and can maintain a circular shape.

When the curved surface curvature of the hinge part 250 is formed to be less than 21 mm, the openability of the cover body 230 may be lowered, so that the cover body 230 may interfere when the contents are taken out. When the curvature value exceeds 24 mm, the hinge part 250 may be bent without being bent in a curved shape. If the thickness dimension of the hinge part 250 is formed to be less than 0.2 mm, it may be repeatedly torn and damaged due to bending. If the thickness dimension exceeds 0.3 mm, bending is not easy.

The position limiting part 260 is formed at one end in the width direction (Y) of the hinge part 250 connected to the base 210 and includes a pedestal 261 and a limiting jaw 262 .

The pedestal 261 has a predetermined width between the base 210 and the hinge part 250 and protrudes upward. The upper surface of the pedestal 261 is formed of an inclined surface 261a. It is inclined downward in the direction of the hinge part 250 from the base 210 . The pedestal 261 is formed along the longitudinal direction of the hinge part 250 . Here, the length of the pedestal 261 may be equal to or greater than the length of the hinge unit 250 .

The limiting jaw 262 protrudes from one side of the inclined surface 261a upward to a length of 0.5 mm to 1.5 mm (262L), and the width direction thickness 262t of the limiting jaw 262 is 0.6 mm to 1 mm. . The limiting jaw 262 is formed with a length of 4.5 mm to 5.5 mm along the longitudinal direction (X) of the pedestal 261 . A plurality of limiting jaws 262 are arranged at equal intervals along the longitudinal direction (X) of the pedestal (261). The number of limiting jaws 262 may be two to four. The upper edge of the limiting jaw 262 is formed in a curved surface.

The tilt prevention part 270 protrudes upward from the other end in the width direction Y of the hinge part 250 , and an inner surface thereof is connected to the inner surface of the hinge part 250 . The upper surface 270a of the tilt prevention part 270 may be in contact with the inclined surface 261a due to the bending of the hinge part 250 , and at this time, the other side may be in contact with the limiting jaw 262 and be in a state of being caught. Accordingly, the tilt prevention unit 270 does not deviate from the position limiting unit 260 . Since the tilt prevention part 270 does not deviate from the pedestal 261 while being caught on the limiting jaw 262 , the cover body 230 can be stably seated in the seating groove 212 without being tilted in the direction of the locking part 220 . And the curved hinge part 250 may be made in a circular shape without being crushed.

The auxiliary hinge 280 connects the hinge part 250 and the cover body 230 . The length of the auxiliary hinge 280 is longer than the length of the hinge part 250 and shorter than the length of the cover body 230 . The area ratio of the hinge part 250 and the auxiliary hinge 280 in a plan view may be 1:0.6 to 0.7. When the area ratio between the hinge part 250 and the auxiliary hinge 280 is formed to be less than 1:0.6 or exceeding 1:0.7, the cover body 230 cannot be stably seated in the seating groove 212 and the seating groove 212 It may deviate from or may not be located in the seating groove 212 .

The auxiliary hinge 280 is formed in a curved shape without being flattened out in the same way as the hinge part 250 when the cover body 230 is unfolded from the base 210 . The curved surface direction of the auxiliary hinge 280 is formed in a direction opposite to the curved surface direction of the hinge part 250 . Accordingly, it is formed convexly from the outside to the inside to form an arcuate shape. A curvature value of the auxiliary hinge 280 is greater than a curvature value of the hinge unit 250 .

A bending groove is formed in the auxiliary hinge 280 in the longitudinal direction. A plurality of bending grooves are formed at intervals along the width direction of the auxiliary hinge 280 .

The first bending groove 281a is formed at one end of the auxiliary hinge 280 and is adjacent to the tilt prevention part 270 , and the second bending groove 281b is formed at the other end of the auxiliary hinge 280 and adjacent to the cover body 230 . do. Here, the thickness t1 of the portion of the auxiliary hinge 280 in which the first bending groove 281a is formed is thinner than the thickness t2 of the portion in the auxiliary hinge 280 in which the second bending groove 281b is formed. The thickness t2 of the portion of the auxiliary hinge 280 in which the second bending groove 281b is formed may be 0.3 mm. Here, the thickness t1 of the part of the auxiliary hinge 280 in which the first bending groove 281a is formed is thicker than the thickness 250t of the hinge part 250 . Accordingly, when the cover body 230 rotates, the hinge part 250 may be bent before the auxiliary hinge 280 .

When the hinge part 250 is bent so that the upper surface 270a of the tilt prevention part 270 comes into contact with the inclined surface 261a for coupling the cover body 230 and the base 210, the locking jaw 210 is the locking part 220 ) does not coincide with the other side of the locking jaw 240 may not be caught in the locking groove (221). At this time, when the other side of the cover body 230 is pressed, the auxiliary hinge 280 portion in which the first bending groove 281a and the second bending groove 281b are formed is bent step by step from the thin portion due to the difference in thickness, and the locking jaw 240 may be caught in the locking groove 221 . Due to the bending of the first bending groove 281a and the second bending groove 281b, the auxiliary hinge 280 of the curved surface is in an unfolded state and an elastic force is generated. Accordingly, when the locking part 220 is pressed in a state in which the cover body 230 closes the opening hole 211 , the cover body 230 is more stable by the elastic force restoring force of the auxiliary hinge 280 and the hinge part 250 . can be opened

The base 210, the cover body 230, the hinge part 250, the position limiting part 260, the tilt prevention part 270 and the auxiliary hinge 280 of the one-touch cover 200 are integrally formed by injection molding. is formed

Next, the operation of the one-touch cover described above will be described.

The process of opening the closed cover body to take out the contents from the container body will be described.

In order to protect the contents contained in the container body 1 , the cover body 230 is in contact with the base 210 and closes the opening hole 211 . The hinge part 250 and the auxiliary hinge 280 are bent to maintain elastic force. When the user presses the locking part 220 , the locking jaw 240 is released from the locking groove 221 , and the lock is released. The cover body 230 is rotated by the elastic force of the hinge part 250 and the auxiliary hinge 280 to separate from the base 210 . The cover body 230 is opened at a predetermined angle with respect to the upper surface of the base 210 to open the opening hole 211 . The periphery of the extraction hole 1a is exposed, and the contents can be withdrawn.

The process of closing the cover body to protect the contents of the container body from dust will be described.

13 to 15 , the user rotates the cover body 230 opened at a predetermined angle with respect to the base 210 in the direction of the base 210 to close the opening hole 211 after withdrawing the contents. . The curved hinge part 250 is formed in a circular shape while being bent in a curved shape. As the tilting prevention part 270 comes into contact with the inclined surface 261a and is caught on the limiting jaw 262 , the tilting prevention part 270 does not deviate from the pedestal 261 . Accordingly, the cover body 230 is not tilted toward one side of the base 210 so that the hinge part 250 is not bent any more. The hinge part 250 is formed in a circular shape of curvature having a predetermined diameter. An elastic force is generated in the circular hinge part 250 , and when the external force for rotating the cover body 230 is removed, the hinge part 250 can return to its original state by the elastic force.

The other side of the cover body 230 in which the locking protrusion 240 is formed while the upper surface of the tilt prevention part 270 is in contact with the inclined surface 261a is lifted from one side of the base 210 on which the locking part 220 is disposed. The locking jaw 240 is in a state that is not caught in the locking groove (221).

When the other side of the cover body 230 is pressed in the direction of the locking part 220, the tilt prevention part 270 is in contact with the inclined surface 261a, so the auxiliary hinge 280 in which the first bending groove 281a and the second bending groove 281b are formed. ) The hooking jaw 240 may be caught in the locking groove 221 as it is bent step by step from the thin part. When the cover body 230 is locked, the cover body 230 is seated in the seating groove 212 to maintain a state in contact with the base 210 .

Accordingly, according to the present embodiment, the upper surface of the tilt-preventing part 270 due to the bending of the hinge part 250 is caught on the limiting jaw 262 while in contact with the inclined surface 261a of the pedestal 261 . Accordingly, the cover body 230 has a limited position and is not tilted in the direction of the locking part 220 , so that the hinge part 250 is not deformed and can maintain a curved state as it is.

Many of the features discussed in the embodiment shown in Figs. 1 to 7 can be applied to this embodiment.
