Definitions

  • the present invention relates to a container cap having a function of maintaining an open state, and more specifically, to a container cap having a function of maintaining an open state, in which the container cap is connected with an indication ring fixed to a spout of a container, and a cap body for opening or closing an opening of the container is maintained while being folded outward from the opening of the container as much as possible in a state in which the opening of the container is opened by the cap body.
  • a container that contains liquid materials such as beverages, oils, paints, chemicals and the like as well as mineral water is formed with a spout to allow the liquid materials to enter and exit.
  • a container cap for opening or closing an opening of the spout of the container is provided on the spout in order to restrict the entrance and exit of the liquid materials.
  • a male screw M/S is formed on an outer peripheral surface E/S of the spout N, which relatively protrudes from the container B, and a female screw F/S is formed on an inner peripheral surface I/S of the container cap 10 covering the spout N correspondingly such that the container cap 10 can be screw-coupled with or released from the spout N of the container B.
  • Korean Patent Publication No. 10-1325850 (packaging container cap: hereinafter referred to as 'related art 1') and Korean Patent Publication No. 10-1038894 (packaging container cap: hereinafter referred to as 'related art 2')
  • the container cap 10 is still connected to the spout N of the container B even when the spout N of the container B is opened in order to eliminate the risk of loss of the container cap 10 separated from the spout N and the possibility of contamination from the surroundings,.
  • the container cap 10 includes a cap body 16 having a ceiling portion 12 and a sidewall portion 14 cylindrically formed downward of the ceiling portion 12 and formed at an inner wall thereof with a female screw F/A, a plurality of bridges 20 provided at a lower portion of the container body 16 and arranged in a radial direction, and an indication ring 18 integrally formed with one side of the container cap 10 through a hinge portion 22.
  • the cap body 16 moves up, but the indication ring 18 disposed between a latching jaw C and a support jaw S/C, which are provided in the container B, is blocked by the latching jaw C without moving up so that the bridges 20 connected to a cut portion 25 between the indication ring 18 and the cap body 16 are broken.
  • the hinge portion 22 described above is connected to the indication ring 18 above the position of the slit 24, and the slit 24 is widened when the cap body 16 moves up from the spout N of the container B, so that the connection state between the indication ring 18 and the cap body 16 can be maintained through the hinge portion 22.
  • a cutout portion 26 which is incised through the cap body 16 and the indication ring 18, is formed on both sides of the hinge portion 22, and the cutout portion 26 is for securing a space to allow the hinge part 22 to be bent inward and outward and has a length from the boundary position between the cap main body 16 and the indication ring 18 in the direction of the cap body 16 located above the indication ring 18.
  • the hinge portion 22 located in the cutout portion 26 has a thin thickness from an inner side to an outer side along the vertical intermediate portion between the cap body 16 and the indication ring 18, and a step portion 28, which is bent in the tangential direction horizontal to the cap body 16 and the indication ring 18 is formed at the position of the hinge portion 22, so that both sides of the step portion 28 in the horizontal direction protrude outward more than surfaces of the cap body 16 and the indication ring 18.
  • both sides of the step portion 28 in the transverse direction of the step portion 28 protrude outward more than the surfaces of the cap body 16 and the indication ring 18, a user may feel inconvenience due to the sense of difference when the user grasps the container and a hand of the user may be damaged when the container cap 10 is fastened with a strong force or when the user attempts to open with excessive force while the contents between the container B and the container cap 10 are hardened.
  • the hinge portion 22 of the related arts 1 and 2 has a step portion 28 so that the cap body 16 can be folded outward from the container B.
  • the folded cap body 16 is eventually positioned to partially cover the opening of the container B under the influence of the elastic restoring force of the hinge portion 22 in the natural state, when the user wants to drink the beverage through the spout N of the container B, the cap body 16 may interfere with the user so that the user has to intentionally fold out the cap body 16.
  • FIG. 3 there is disclosed a technique in Korean Patent Publication No. 10-0981240 (hereinafter referred to as 'related art 3'), in which a support 32 is provided in the hinge portion 22' such that an end of the support 32 can be supported against an outer wall of the container spout, thereby securely maintaining the open state of the cap body 16.
  • 'related art 3' Korean Patent Publication No. 10-0981240
  • the position of the end of the support 32 mentioned above is located above the slit 24.
  • the above-mentioned length d1-d3 of the twisted section includes the protruding length d3 of the support 32, and finally, the twisted section d1-d3 may form a space larger than a margin space D in a state in which the spout N of the container B is twisted against the outer wall, so that it is difficult to exert a support force onto the support 32.
  • the cap body 16 is located in a position covering the opening of the spout N of the container B due to the restoring force against the twist.
  • the position of the upper portion of the cutout portion 28 leading to an upper side of the cap body 16 is formed up to a maximum upper position which does not interfere with the female screw F/S formed in the inner wall of the cap body 16, and the length of the support 32 has to be long enough at that position.
  • the extension of the length of the support 32 may not allow the support 32 to closely adhere to the inner wall of the spout N of the container B, but allow the support 32 to be suspended to the inner wall of the spout N of the container B.
  • the folding angle of the cap body 16 from the opening of the container B may be less than 90°, which causes the user to take the action to move the cap body 16 away from the opening of the container B by a hand to prevent interference.
  • related art 3 has a protrusion T in the support 32 such that the protrusion T can be suspended to the latching jaw C or the male screw M/S formed in the spout N of the container B.
  • the protrusion T protrudes from an outer surface of the cap body 16 in a state where the opening of the spout N of the container B is closed, so that the protrusion T may interfere with the user when the user attempts to open the opening of the container B.
  • connecting positions P1 to P3 between the indication ring 18 on the upper side of the slit 24, the hinge portion 22, and the cap body 16 are forcibly twisted.
  • a thin portion in the connecting positions P1 to P3 may be easily broken by the physical force derived from the force to restore from the twisted state and the supporting force of the support so that the cap body 16 may be lost.
  • KR 100 981 240 B1 discloses a package container stopper equipped with a brace for preventing idle having a fixing ring which is fixed to a container main body, a stopper main body which opens the container main body and includes a screw part on the inner circumference of the stopper main body, a hinge part for connecting the fixing ring to the stopper main body, and a plurality of bridges which are included between the stopper main body and the fixing ring.
  • the fixing ring includes a cutting line.
  • the present invention has been made to solve the above-mentioned problems of the related arts, and an object of the present invention is to provide a container cap having a function of maintaining an open state, which can be maintained in a stable state by preventing damage or breakage of the connection state between a cap body and an indication ring even when the container cap is continuously used, and can ensure that the cap body is located in a position completely out of an opening of a container spout when using a container, such as for drinking a beverage.
  • a container cap having a function of maintaining an open state
  • the container cap including: 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 portion connecting the cap body and the indication ring to each other in a partial section of a circumference of a cut portion disposed between the cap body and the indication ring; and a bridge which connects the cap body and the indication ring at an interval along a circumference of the cut portion and is cut when the cap body is open, wherein the hinge portion has widthwise opposite edge parts adjacent to opposite ends of the cut portion and depressed from an outer side to an inner side thereof, two bending guide grooves formed to be integrally connected to the cap body, the indication ring, and the hinge portion, and a protrusion portion having a shape extending and protruding downward from a lower part of the widthwise center thereof; and the indication
  • Each bending guide grooves may have a depth from an outer side to an inner side thereof, and form an inclined surface having a thickness gradually reduced from a widthwise center of the hinge portion to an outer edge thereof, thereby allowing a part of the bending guide portion adjacent to the cap body in a height direction at the opposite ends of the cut portion having a relatively thin thickness to be cut.
  • a twist groove having a width, a length and a depth defined from an outside to an inside thereof is formed in opposite sides of the indication ring provided at an upper side of the slit on opposite sides of the hinge portion, at least one twist groove is formed along the indication ring, and the twist groove has a predetermined gradient with respect to a vertical direction such that one upper end of each twist groove in a longitudinal direction of the twist groove is adjacent to the hinge portion and one lower end of each twist groove is adjacent to an end of the slit.
  • the cap body in contact with the bending guide groove is integrally connected with the hinge portion and the indication ring portion provided at an upper side of the slit, and the protrusion portion is located lower than a horizontal position of the slit, so that the protrusion portion is supported against the container spout by the strong force in response to the twist restoring force of the twisted indication ring, which is continuously twisted from both ends of the slit to the hinge portion, and the tension including the twist restoring force when the cap body is opened.
  • the bending angle of the cap body with respect to the container spout can be enlarged as compared with that of the related arts. Therefore, the cap body can be stably located without interfering with the contents when the contents flow out through the opening of the container spout.
