CONTAINER CAP HAVING FUNCTION OF MAINTAINING OPEN STATE

Abstract

A container cap configured to maintain an open state includes an indication ring prevented from escaping from a container spout; a cap body screw-coupled to an outer circumferential surface of the container spout; a hinge connecting the cap body and the indication ring to each other in a partial section of a circumference of a cut portion between the cap body and the indication ring; and a bridge connecting the cap body and the indication ring at an interval along the circumference of the cut portion and is cut when the cap body is open. The hinge has widthwise opposite edges adjacent to opposite cut portions and depressed from the outer to inner sides thereof, a bending guide groove integrally connected to the cap body, the indication ring, the hinge portion, and a protrusion having a shape extending and protruding downward from a lower part of the widthwise center thereof.

[0037] the indication ring includes a slit formed in a predetermined section of a middle part in a vertical height direction thereof and a concave portion disposed at a position corresponding to the protrusion portion, adjacent to the protrusion portion while being spaced apart therefrom, and depressed downward.

MODE FOR INVENTION

[0038] The terms or words used in the specification and claims of the present invention are not to be construed as being limited to the ordinary or dictionary meanings, but the inventors may properly interpret the concept of terms in order to explain their own invention in the best way. It can be defined as definable and should be interpreted as meanings and concepts corresponding to the technical spirit of the present invention.

[0039] In addition, the structure described in the embodiments and shown in the drawings of the present invention is only for an exemplary embodiment of the present invention and does not represent all the technical idea of the present invention. It should be understood that various equivalents and modifications that can be substituted for the present invention at the time of filing of the present invention may fall within the claims of the present invention.

[0040] Further, In the description of the present invention, a container is in an upright state, that is, a state in which a spout of the container is on the upper side, and the expression of the inside refers to a central direction of the inside of the container or a portion in the inner direction at the corresponding height and the expression of the outside refers to a direction opposite to the inside or a portion in the outer direction.

[0041] Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0042] As shown in FIGS. 5 to 7, similar to the related arts, the container cap 40 having a function of maintaining an open state according to the present invention may include an indication ring 44, which can be prevented from being separated by a latching jaw C formed in a spout N of a container B, a cap body 42 screw-coupled to an outer peripheral surface E/S of the spout N of the container B and having a lower portion spaced apart from an upper side of the indication ring 44 to form an cut portion 52, a hinge portion connecting the cap body 42 and the indication ring 44 to each other in a partial section of a circumference of the cut portion 52 disposed between the cap body 42 and the indication ring 44, and a bridge 20 that supports an interval between the cap body 42 and the indication ring 44 along the circumference of the cut portion 52 and cut as the interval of the cut portion 52 is enlarged when the cap body 42 is opened.

[0043] In the above-described configuration, the hinge portion 56 according to the present invention has widthwise opposite edge parts adjacent to ends of opposite cut portions 52 and depressed from the outside to the inside thereof, and a bending guide groove 48 formed to be integrally connected to the cap body 42, the indication ring 44, and the hinge portion 56.

[0044] The bending guide groove 48 has a depth from an outer side to an inner side thereof, and forms an inclined surface having a thickness gradually reduced from a widthwise center of the hinge portion 56 (circumferential direction of the cap body 42) to an outer edge thereof, so that a portion of the bending guide portion 48 is thin at the sidewall of the cap body 42 formed at an upper side adjacent to the cut portion 52.

[0045] The thinly formed portion of the bending guide groove 48 may form a cutout line O/L such that the cutting can be gradually performed from the thin portion under the tension applied to the indication ring 44a located at an upper side of the slit 46 in a section between both ends of the slit 46 when the cut portion 52 is enlarged in the process of opening of the cap body 42.

[0046] In addition, a portion where the thickness of the bending guide groove 48 gradually increases in the widthwise center direction of the hinge portion 56 may not be gradually cut in response to the tension acting on the indication ring 44a in the above-described section. That is, the portion is provided to endure the tension acting on the indication ring 44a without incision.

[0047] Further, the hinge portion 56 described above has a protrusion portion 50 that protrudes downward at the lower portion of the widthwise center of the hinge portion 56, that is, the lower portion of the indication ring 44a on the upper side of the slit 46 which is integrally connected.

[0048] In addition, a concave portion 49 having a depth defined downward is formed at an upper portion of the indication ring 44b provided at a lower portion of the slit 46 corresponding to the protrusion portion 50 such that the concave portion 49 has a shape corresponding to a shape of the protrusion portion 50 at a predetermined interval.

[0049] Therefore, the above-described slit 46 may be formed along an intermediate portion of the vertical direction of the indication ring 44 and extend to be connected to the concave portion 49 having a depth defined downward at a position corresponding to the protrusion portion 50.

[0050] In addition, at least one twist groove 54 having a width, a length and a depth defined from an outside to an inside thereof may be formed in the above-described section, that is, the section of the indication ring 44a provided on the upper side of the slit 46, which extends from both ends of the slit 46 to both ends of the cut portion 52.

[0051] In addition, the twist groove 54 has a shape in which a longitudinal direction is inclined with respect to a vertical direction at a predetermined angle, and specifically, one upper end of the twist groove 54 in the longitudinal direction is adjacent to the hinge portion 56 and one lower end of the twist groove 54 is adjacent to an end of the slit 46.

[0052] In a state in which the cap body 42 is opened, the force of restoring the original shape is provided while the indication ring 44 on the upper side of the slit 46 is twisted. The restoring force may provide a rotational force to the cap body 42 to cover the opening of the spout N of the container B, and the above-described twist groove 54 induces deformation of the twisted state to relieve the restoring force due to the twist.

[0053] That is, the twist groove 54 is provided to allow the above section to be easily twisted while allowing the tension to be applied only onto the section of the indication ring 44 provided at the upper side of the slit 46 extending from both ends of the slit 46 to both ends of the cut portion 52 in a state in which the cap body 42 is opened.
