  • the present invention relates to a detachable resin cap used for a mouth portion of a container such as a plastic bottle.
  • the top plate portion As such a resin cap, the top plate portion, the cylindrical portion hanging from the periphery of the top plate portion, the outer ring formed on the inner surface of the top plate portion and in contact with the outer peripheral surface of the container mouth portion, and the top plate
  • An inner ring formed on the inner surface of the container and in contact with the inner peripheral surface of the container mouth, and the container mouth with the inner ring having a longer length (vertical distance from the top plate) than the outer ring and the outer ring. What seals a container by pinching is widely used.
  • a contact ring that comes into contact with the tip of the container mouth is usually formed on the inner surface of the top plate portion together with the outer ring and the inner ring (see, for example, Patent Document 1).
  • the contact ring was originally provided to define the end position when the resin cap is mounted, but in recent years, it is also used to seal the container, like the outer ring and the inner ring.
  • containers such as PET bottles are sterilized by heating in a state where a resin cap is attached to the mouth after filling the contents.
  • the contact state between the outer ring or inner ring and the container mouth portion may deteriorate, and the sealing performance of the container may deteriorate.
  • heat sterilization may be performed in a state where the container is turned over, in this case, since the heated contents come into contact with the inner ring, the inner ring softens, and the container mouth portion The contact state with may further deteriorate.
  • the outer seal is in contact with the high-temperature atmosphere, so the outer seal may be softened and the sealing performance of the container may be reduced.
  • This invention is made in view of such a situation, and it aims at providing the resin-made cap which can suppress the fall of the sealing performance of the container resulting from heat sterilization.
  • a characteristic configuration of the resin cap according to the present invention is mounted on a container mouth portion, formed on the top plate portion, a cylindrical portion depending from the periphery of the top plate portion, and an inner surface of the top plate portion, and the container mouth
  • the contact ring is configured to be displaceable by contact with the tip of the container mouth, so that even if the container mouth is softened and displaced by heat sterilization, the contact ring follows the displacement. Therefore, it is possible to suppress a decrease in sealing performance of the container due to heat sterilization.
  • the contact ring does not come into direct contact with the heated liquid, so it is less susceptible to softening due to heat sterilization. There is also.
  • a further characteristic configuration of the present invention is that the contact ring has a shape having a constricted portion.
  • the contact ring can be easily displaced.
  • a further characteristic configuration of the present invention is that the contact ring has a shape curved in the radial direction of the top plate portion in a state where the contact ring is not in contact with the tip portion of the container mouth portion.
  • FIG. 3 is a cross-sectional view taken along line III-III in FIG. It is a principal part enlarged view which shows the modification of the resin-made caps of this invention, (A) shows the state in the middle of mounting
  • the resin cap 10 according to the present embodiment is used for a resin container mouth portion 20.
  • the resin cap 10 according to the present embodiment is formed on the top plate portion 11, the cylindrical portion 12 hanging from the periphery of the top plate portion 11, and the inner surface of the top plate portion 11.
  • the contact ring 15 that contacts the tip of the container mouth 20 is provided, and the contact ring 15 can be displaced by contact with the tip of the container mouth 20.
  • the material and manufacturing method of the resin cap 10 are not particularly limited.
  • a resin such as polyethylene or polystyrene is used, and the top plate portion 11, the cylindrical portion 12, the outer ring 13, the interring 14, and the contact ring. 15 can be manufactured by injection molding integrally.
  • the top plate portion 11 of the resin cap 10 is formed in a disc shape in accordance with the shape of the container mouth portion 20, and the outer periphery of the container mouth portion 20 is provided with a thread 12 a on the inner peripheral surface of the tube portion 12.
  • the resin cap 10 is attached to the container opening 20 by screwing with a screw thread 20a formed on the surface.
  • the outer ring 13, the inner ring 14, and the contact ring 15 have a shape protruding from the inner surface of the top plate portion 11.
  • the inner peripheral surface of the outer ring 13 is the outer peripheral surface of the container mouth portion 20
  • the outer peripheral surface of the inner ring 14 is the inner peripheral surface of the container mouth portion 20
  • the tip of the contact ring 15 is the tip of the container mouth portion 20, respectively.
  • the container is sealed by contact.
  • the outer ring 13 has a shape in which a part of the outer peripheral surface is in contact with the inner peripheral surface of the container mouth portion 20.
  • various general shapes other than the shapes shown in FIGS. 1 to 3 can be adopted. The same applies to the inner ring 14.
  • the contact ring 15 is configured to be displaceable by contact with the distal end portion of the container mouth portion 20, and is formed in a shape having a constricted portion 15a in the present embodiment.
  • the contact ring 15 functions like a spring, and the contact ring 15 can be displaced in accordance with the contact with the tip of the container mouth portion 20. Even when softened and displaced, the contact ring 15 can be made to follow the displacement of the container mouth part 20 and the contact between the container mouth part 20 and the contact ring 15 can be maintained.
  • the contact ring 15 when the contact ring 15 is made narrower (the length in the radial direction), the movable range becomes larger and it becomes easier to follow the displacement of the container mouth part 20, but on the other hand, the contact ring 15 and the container mouth part 20 The contact area of the contact ring 15 becomes small, and the sealing performance of the contact ring 15 tends to decrease.
  • the contact ring 15 has a tapered portion whose width is narrowed from the top plate portion 11 side toward the distal end portion of the container mouth portion 20 around the constricted portion 15a, and the container mouth portion 20.
  • the contact tape 15 has a contact area between the contact ring 15 and the container mouth portion 20 while increasing the movable range of the contact ring 15. By increasing the size, both the mobility and the sealing performance of the contact ring 15 can be achieved.
  • the length of the contact ring 15 is a range in which the tip of the contact ring 15 can contact the tip of the container mouth 20 when the resin cap 10 is attached to the container mouth 20.
  • the thickness is not particularly limited, but is preferably about 0.1 to 0.5 mm.
  • the width of the tip of the contact ring 15 is preferably about 0.1 to 1.0 mm.
  • the width of the constricted portion 15a is preferably about 4/5 to 1/5 of the maximum width of the contact ring 15.
