Description

  The present invention relates to a detachable resin cap used for a mouth portion made of non-crystallized resin of a container such as a PET bottle.

  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 that is formed on the inner surface of the container and is in contact with the inner peripheral surface of the container mouth portion, and the inner ring has a longer length (vertical distance from the top plate) than the outer ring and the outer ring. What seals a container by pinching a part is widely used (there is no appropriate literature showing this prior art).

  On the other hand, there are two types of resin-made mouth parts such as plastic bottles, a crystallized white type (crystallization container mouth part) and a non-crystallized transparent type (non-crystal container mouth part). . In general, the crystallization container mouth portion is used with a thickness of about 1.6 mm because the resin strength is improved by thermal crystallization, and the amorphous container mouth portion is stronger than the crystallization container mouth portion. Since it is low, it is used while maintaining strength by setting the thickness to 2 mm or more (approximately 2.2 mm).

  When a container having an amorphous container mouth is filled with the contents at a high temperature and a resin cap is attached, the amorphous container mouth is softened by heat, and the inner ring falls down due to the pressure of the outer ring. Since there is a concern that the sealing performance is lowered, a crystallization container mouth portion having high heat resistance is usually used for a container filled with high-temperature contents. However, since the crystallization vessel mouth portion requires a crystallization process, there is a problem that the cost of equipment becomes high or quality control becomes difficult due to control of variation in the crystallization process. .

  In view of the above problems, in recent years, in containers filled with high-temperature contents, it has begun to be considered to give heat resistance by increasing the thickness of the amorphous container mouth, but in the amorphous container mouth, Since there is a risk that the above-mentioned inward collapse occurs, there is no resin cap having a structure in which the outer ring is firmly pressed against the thick amorphous container mouth, and there is room for improvement in terms of sealing performance.

  The present invention has been made in view of such a situation, and even when used for a container mouth portion made of an uncrystallized resin having a tip thickness of 2 mm or more, the container has good sealing performance. It aims at providing the resin-made caps which can be maintained in this.

As a result of intensive studies, the present inventors have made it difficult to cause internal collapse due to heat softening by setting the thickness of its tip to 2 mm or more even in a container mouth portion made of a resin that has not been crystallized. Furthermore, to invent a cap structure of a new idea that can improve the sealing performance by making the inner surface of the outer ring of the cap conform to the shape of the outer surface of the container mouth and making the outer ring firmly contact the outer surface of the container mouth. It came.
That is, the characteristic configuration of the resin cap according to the present invention is used for a container mouth portion made of an uncrystallized resin having a tip thickness of 2 mm or more, and hangs down from the top plate portion and the periphery of the top plate portion. A cylindrical portion, an 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, an inner ring formed on the inner surface of the top plate portion and in contact with the inner peripheral surface of the container mouth portion A ring-shaped resin cap, wherein the inner peripheral surface of the outer ring is shaped along the outer peripheral surface of the tip of the container mouth portion.

  According to this structure, the contact area of an outer ring and a container opening part can be enlarged compared with a conventional product. Thereby, when using for the container opening part whose thickness of a front-end | tip is 2 mm or more, it becomes possible to maintain the sealing performance of a container favorably.

  According to a further characteristic configuration of the present invention, the resin cap includes a support portion that is formed between the outer ring and the cylindrical portion on the inner surface of the top plate portion and contacts the outer peripheral surface of the outer ring. It is in.

  According to this configuration, since the outer ring can be reinforced by the support portion from the direction opposite to the pressure received from the container mouth, deformation of the outer ring to the outside can be further suppressed.

  The further characteristic structure of this invention exists in the point in which the said support part is formed over the said outer ring and the said cylinder part.

  According to this structure, the reinforcement effect of the outer ring by a support part can be heightened.

  The further characteristic structure of this invention exists in the point by which the said support part is comprised by the some rib arrange | positioned at substantially equal intervals along the circumferential direction of the said outer ring.

  According to this configuration, the effect of reinforcing the outer ring by the support portion can be enhanced without greatly increasing the weight of the resin cap.

It is sectional drawing which shows the state which mounted | wore the container mouth part with the resin caps of this invention. It is a principal part enlarged view in FIG. It is a perspective view which shows the inside of the resin caps of this invention. It is sectional drawing of the IV-IV line in FIG.

  Hereinafter, the resin cap of the present invention will be described with reference to the drawings.

[Embodiment 1]
As shown in FIG. 1, the resin cap 10 according to the present embodiment is used for a resin container mouth portion 20 that is not crystallized.
As shown in FIGS. 1 and 2, 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. An outer ring 13 in contact with the outer peripheral surface of the container mouth portion 20, and an inner ring 14 formed on the inner surface of the top plate portion 11 and in contact with the inner peripheral surface of the container mouth portion 20. The inner peripheral surface has a shape along the outer peripheral surface at the tip of the container mouth 20 (a shape substantially parallel to the outer peripheral surface at the tip of the container mouth 20).

  The material and manufacturing method of the resin cap 10 are not particularly limited. For example, a resin such as polyethylene or polystyrene is used, and the top plate portion 11, the cylindrical portion 12, the outer ring 13, and the interring 14 are integrated. It can be manufactured by injection molding.

  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 and the inner ring 14 have a shape protruding from the inner surface of the top plate portion 11. While the inner peripheral surface of the outer ring 13 and the outer peripheral surface of the container mouth portion 20 are in contact, the outer peripheral surface of the inner ring 14 and the inner peripheral surface of the container mouth portion 20 are in contact with each other, so that the container is sealed.

As shown in FIGS. 1 and 2, the outer ring 13 has an inner peripheral surface formed in a shape along the shape of the outer peripheral surface at the tip of the container mouth portion 20. As a result, when the container was filled with high-temperature contents, the container opening 20 was inserted deeply into the resin cap 10 as shown in FIGS. 1 and 2 and sealed, or high-temperature sterilization was performed in that state. Even so, it is possible to suppress inward tilting of the container mouth portion 20 and deformation of the outer ring 13 to the outside, and to maintain a close contact state between the outer ring 13 and the outer peripheral surface of the container mouth portion 20.
Further, the front end of the outer ring 13 is set so as to be positioned closer to the front end side of the container mouth part 20 than the thread 20a when the resin cap 10 is attached to the container mouth part 20. The length protruding from the inner surface of the top plate portion 11 of the outer ring 13 is not particularly limited and can be set to a length similar to that of a conventional resin cap. The degree of adhesion between the cap 10 and the container mouth portion 20 can be improved.

  On the inner surface of the top plate portion 11, a support portion 15 that extends between the outer ring 13 and the cylindrical portion 12 is formed on the outer ring 13. That is, the support portion 15 is formed in contact with the outer peripheral surface of the outer ring 13 and the inner peripheral surface of the cylindrical portion 12, whereby the outer ring 13 is reinforced and the outer ring 13 is further deformed outward. It is suppressed.

  In the present embodiment, the support portion 15 is composed of twelve ribs 16 arranged at equal intervals along the outer peripheral surface of the outer ring 13 as shown in FIGS. Thereby, the reinforcement effect of the outer ring 13 by the support portion 15 can be enhanced without greatly increasing the weight of the resin cap 10.

  The ribs 16 are arranged so as to be inclined in the same direction with respect to the radial direction of the outer ring 13. Thereby, while enhancing the reinforcing effect of the outer ring 13 by the rib 16, it is possible to suppress the rib 16 from excessively pressing the outer ring 13, and to prevent the outer ring 13 from being damaged and the cylindrical portion 12 from being deformed.

  Further, from the viewpoint of ensuring a sufficient reinforcing effect, the height of the support portion 15 (rib 16) is preferably 50% or more of the height of the outer ring 13, and more preferably 70% or more. . The upper limit of the height of the support portion 15 (rib 16) is not particularly limited as long as it does not interfere with the screw thread 20a of the container mouth portion 20 and the screw thread 12a of the tube portion 12, but the reinforcing effect, cost, and weight are not limited. Considering the balance, it is preferably 100% or less of the outer ring 13.

  In the present embodiment, the shape of the inner ring 14 exemplifies a case where a part of the outer peripheral surface abuts on the inner peripheral surface of the container mouth portion 20 as shown in FIGS. The shape is not particularly limited as long as the shape can be brought into contact with 20, and various general shapes other than the shapes shown in FIGS.

  In the present embodiment, the container mouth portion 20 is a transparent type that is not crystallized, and the thickness of the tip is set to 2.2 mm. The upper limit of the thickness of the tip of the container mouth portion 20 is not particularly limited, and may be about 3 to 4 mm.

  The container having the container mouth part 20 is not particularly limited as long as the thickness of the tip of the container mouth part 20 is 2 mm or more. For example, it is made of a resin for beverages made from a synthetic resin such as polyethylene phthalate. Can be applied to containers. In particular, it is suitable for resin containers used for fruit juice drinks, sports drinks, teas, and the like, in which the contents are filled at a high temperature.

[Other Embodiments]
In the above embodiment, the case where twelve ribs 16 are provided and arranged at equal intervals is illustrated, but the number of ribs 16 is not limited to this, and an arbitrary number of ribs 16 can be arranged. Considering the balance between the reinforcing effect and the cost and weight, the number of ribs 16 is preferably 6 to 24. Further, the ribs 16 do not have to be arranged at regular intervals as long as they are substantially equidistant, and there may be some non-uniform spacing.

  In said embodiment, although the case where the shape of the rib 16 was formed over the outer ring 13 and the cylinder part 12 was illustrated, the shape of the rib 16 is not limited to this. For example, if the outer ring 13 is in contact with the outer peripheral surface, the outer ring 13 can be reinforced even if it is separated from the inner peripheral surface of the cylindrical portion 12. Further, in the present embodiment, the rib 16 is provided substantially parallel to the top plate portion 11. However, for example, the rib 16 may be shaped so that the distance from the top plate portion 11 decreases as the distance from the outer ring 13 increases. it can.

  In the above-described embodiment, the case where the ribs 16 are disposed so as to be in the same direction obliquely with respect to the radial direction of the outer ring 13 is exemplified, but the present invention is not limited to this. Or adjacent ribs 16 may be provided obliquely in different directions.

  In the above embodiment, the case where twelve ribs 16 having the same shape are arranged is illustrated, but the present invention is not limited to this. For example, a plurality of differently shaped ribs 16 can be arranged, or two types of shaped ribs 16 can be arranged alternately, and can be set arbitrarily.

  In said embodiment, although illustrated about the case where the support part 15 was comprised as the some rib 16, it is not limited to this. For example, the support portion 15 can be configured by an annular member along the outer periphery of the outer ring 13.
