Definitions

  • the present invention relates to a package comprising a metallic container and a metallic cap fitted to the mouth portion of the metallic container.
  • a metallic cap fitted to the mouth portion of a metallic container usually includes a top panel, a skirt hanging down from the circumferential edge of the top panel, and a plastic liner adhered and fixed to the inner surface of the top panel.
  • a tamper evident band (TE band) is formed via a breakable bridge.
  • the cap is turned in a direction in which it is to be opened whereby the screw engagement is liberated from the container mouth portion, and the cap can be removed from the container mouth portion.
  • the TE band engages with the lower portion of the container mouth portion and is limited from rising. Therefore, the bridge connecting the TE band to the skirt breaks, and the TE band is separated away from the skirt. That is, the TE band is separated away from the cap after it is opened and, as a result, the user in general is allowed to recognize the fact that the cap was opened.
  • the above feature is called tamper evidence (TE) and is an important feature required for the cap from the standpoint of preventing the tampering and guaranteeing the quality of the content in the container.
  • JP-A-2006-188279 proposes a package as in the preamble of claim 1, in which a curled portion is formed on the outer side at the upper end of the mouth portion of a metallic container, and a circular ring is formed at the outer circumferential edge portion of the liner of the metallic cap, the circular ring having an inner surface that is curved inward (protruding inward) from the upper side toward the lower side.
  • US-A-4,114,775 discloses a cap having a metallic cap shell with a circular top and a skirt extending downwardly from the peripheral edge of the top and provided with a thread-forming portion deformable along the thread of the opening part of a container, and a flexible liner provided inwardly of the top of the cap shell.
  • the liner includes an annular protrusion having an inside diameter substantially equal to, or slightly larger than, the outside diameter of the sealing surface of the opening of a container to be sealed and comprising a perpendicular inside wall adapted to seal intimately with the peripheral sealing surface of the container opening and an upright outside wall spaced apart from the inner circumferential surface of the skirt.
  • the liner is provided with the outer ring and the inner ring, and the whole surface of from the inner surface of the outer ring up to the outer surface of the inner ring is brought into close contact with the upper end of the container mouth portion to form the sealing structure. Therefore, a large torque is required for the opening; i.e., difficulty is involved for the opening.
  • an object of the present invention to provide a package comprising a metallic container and a metallic cap fitted to the mouth portion of the container, effectively preventing the breakage of the sealing prior to the breakage of the bridge that connects the TE band, and featuring favorable resealing.
  • Another object of the present invention is to provide a package which requires a small torque for opening and enables the metallic cap to be easily opened.
  • the inner protruded portion formed at the lower end of the inner surface of the outer ring of the liner rises maintaining a close contact with the side wall portion at the upper end of the container mouth portion and with the upper curled portion. Therefore, the cap can be turned over an increased angle before the sealing is broken and, as a result, the breakage of the sealing is effectively prevented before the bridge connecting the TE band is broken.
  • the inner surface of the outer ring of the cap is extending straight in the vertical direction. Besides, the corner portion has been formed by draw working.
  • the inner protruded portion of the outer ring enables the outer ring of the liner to easily descend along the outer surface (upper curled portion and the outer surface of the side wall portion) of the open end of the container mouth portion, making it easy to accomplish resealing.
  • a gap is formed between the outer circumferential surface of the outer ring and the skirt at a position at least on the outer side of the lower portion of the side wall portion in the direction of diameter thereof, which imparts an increased degree of freedom to the outer ring of the liner at the time of resealing, enabling the outer ring of the liner to easily descend along the outer surface (upper curled portion and the outer surface of the side wall portion) of the open end of the container mouth portion, making it easy to accomplish resealing.
  • a region which does not adhere to the inner surface of the top panel is formed along the outer circumferential edge portion of the liner.
  • an increased degree of freedom is imparted to the outer ring of the liner enabling the outer ring of the liner to easily descend along the outer surface (upper curled portion and the outer surface of the side wall portion) of the open end of the container mouth portion, making it easy to accomplish resealing.
  • a surface between the lower end of the inner surface of the outer ring and the lower end of the outer surface of the outer ring of the liner is tapered being tilted downward from the inner surface side thereof toward the outer surface side thereof.
  • the tapered surface serves as a guide and enables the outer ring of the liner to easily descend along the outer surface (upper curled portion and the outer surface of the side wall portion) of the open end of the container mouth portion, making it easy to accomplish resealing.
  • a recessed portion may be formed in the surface positioned between the outer ring and the inner ring of the liner at either a portion positioned on the inner ring side or a portion positioned on the outer ring side in a state before the mouth portion of the container is wrap-seamed with the cap.
  • the surface pressure of the liner decreases relative to the open end of the container mouth portion.
  • a small torque is required for the opening and the metallic cap can be easily opened.
  • a package of the present invention is constituted by a metallic container having a mouth portion generally designated at 1 and a cap generally designated at 3.
  • An open end of the container mouth portion 1 includes an upper curled portion 1a formed at an upper end thereof, a side wall portion 1b hanging down vertically from the upper curled portion 1a and a lower curled portion 1c extending inward from the lower end of the side wall portion 1b (see Fig. 2 ). Further, a shoulder portion 5 is formed on the lower side of the open end of the container mouth portion 1, the shoulder portion 5 extending downward and being tilted outward. A screw thread 7 is formed on the lower side of the shoulder portion 5, and a flange portion 9 is formed on the lower side of the screw thread 7.
  • the metallic cap 3 on the other hand, includes a top panel 10 and a skirt 11 hanging down from the circumferential edge of the top panel 10. Horizontal slits 12 for venting are formed in the upper portion of the skirt 11 maintaining a suitable gap, and a tamper evident band (TE band) 15 is formed at the lower end of the skirt 11 via a breakable bridge 13 (see Fig. 2 ). A plastic liner 17 is adhered and fixed to the inner surface of the top panel 10.
  • TE band tamper evident band
  • a screw thread 19 is formed on the skirt 11 to engage with the screw thread 7 that is formed on the mouth portion 1 of the container, and the cap 3 is firmly fixed to the mouth portion 1 of the container due to the engagement of the threads. Further, the lower portion of the TE band 15 is draw-formed to engage with the flange portion 9 of the container mouth portion 1.
  • An outer ring 20 that is hanging down is formed at an outer circumferential end of the liner 17, and an inner ring 21 that is also hanging down is formed maintaining a gap to the outer ring 20.
  • the open end of the container mouth portion 1 enters into a space between the outer ring 20 and the inner ring 21 to accomplish a predetermined sealing.
  • the TE band 15 remains engaged with the flange portion 9 of the container mouth portion 1, and is limited from rising. Therefore, if the cap 3 is opened, the bridge 13 connecting the TE band 15 breaks. As a result, the TE band 15 is cut away from the cap 3 that is removed from the container mouth portion 1, and the fact that the cap 3 is opened can be recognized.
  • the liner 17 has a structure as described below.
  • a region X that does not adhere to the inner surface of the top panel 10 is formed along the outer circumferential edge portion of the liner 17.
  • the region X that does not adhere is for forming a favorably sealed structure by the draw working that will be described later.
  • the inner surface 20a of the outer ring 20 of the liner 17 extends straight in the vertical direction.
  • the surface between the lower end of the inner surface 20a and the lower end of the outer surface 20b of the outer ring 20 is forming a tapered surface 20c being tilted downward from the side of the inner surface 20a toward the side of the outer surface 20b.
  • the sealed structure is formed by draw-forming the corner portion from the top panel 10 to the skirt 11 while pushing the cap 3 from the upper direction in a state where the cap 3 is placed on the mouth portion 1 of the container that is filled with a predetermined content and the open end of the container mouth portion 1 is inserted in a space between the outer ring 20 and the inner ring 21.
  • the skirt 11 and the TE band 15 are so formed as to comply with the outer surface of the container mouth portion 1. Therefore, the screw thread 19 is formed on the skirt 11 so as to engage with the screw thread 7 of the container mouth portion 1, and the TE band 15 engages at its lower end with the flange portion 9 that is formed on the container mouth portion 1.
  • the region X that does not adhere is formed along the outer circumferential edge portion of the liner 17. Therefore, the draw-forming can be easily accomplished as described above, the surface between the outer ring 20 and the inner ring 21 of the liner 17 comes into close contact with the upper curled portion 1a of the open end of the container mouth portion 1, the inner surface (vertical surface) 20a of the outer ring 20 comes into close contact with the outer surface of the side wall portion 1b formed at the open end of the container mouth portion 1, and an inner protruded portion 23 protruding inward is formed at the lower end of the inner surface 20a of the outer ring 20 so as to come into close contact with the outer portion of the lower curled portion 1c of the container mouth portion 1, to thereby form the sealed structure.
  • the inner ring 21 is for accomplishing the centering when the cap 3 is placed on the open end of the container mouth portion 1.
  • the outer surface of the inner ring 21 is in slight contact with the inner surface of the open end of the container mouth portion 1 but does not directly take part in the sealing structure.
  • the inner protruded portion 23 formed at the lower end of the inner surface 20a of the outer ring 20 rises maintaining a close contact with the outer surface of the side wall portion 1b of the open end of the container mouth portion 1 ( Fig. 4(a) ).
  • the inner protruded portion 23 comes into close contact with the upper curled portion 1a of the open end of the container mouth portion 1 ( Fig. 4(b) ).
  • the inner protruded portion 23 separates away from the upper curled portion 1a, whereby the sealing is broken and the cap 3 is removed from the container mouth portion 1.
  • the sealed structure is maintained until the inner protruded portion 23 formed on the outer ring 20 separates away from the side wall portion 1b of the open end of the container mouth portion 1, and the sealing is not broken within short periods of time after the start of opening. Therefore, the bridge 13 connecting the TE band 15 is broken before the sealing is broken, and the cap 3 of which the bridge 13 has not been broken reliably represents that the sealed structure has not been broken. Thus, a favorable tamper evidence is maintained. According to the present invention, therefore, it is desired that the length L of the side wall portion 1b of the open end of the container mouth portion 1 (see Fig. 2 ) is set to be from 0.5 to 2.3 mm. If the length is too small, the time becomes short from the start of opening to the breakage of sealing, and the bridge 13 tends to be easily broken after the sealing is broken.
  • the cap 3 once removed from the container mouth portion 1 and from which the TE band 3 has been separated away, can be resealed as described below. Namely, the cap 3 is placed on the open end of the container mouth portion 1 and is turned in the direction of sealing. The cap 3 finally descends to the lowermost state shown in Fig. 2 from the state of Fig. 4(b) through the state of Fig. 4 (a) to form the sealed structure again.
  • the surface between the lower end of the inner surface 20a and the lower end of the outer surface 20b of the outer ring 20 is forming a tapered surface 20c being tilted downward. Therefore, the tapered surface 20c works to easily guide the liner 17 into the positional relationship shown in Fig.
  • the above tapered surface 20c is not formed, and the surface between the lower end of the inner surface 20a and the lower end of the outer surface 20b of the outer ring 20 is forming a horizontal surface, then this surface is caught by the upper curled portion 1a of the open end of the container mouth portion 1, making it difficult to smoothly accomplish the resealing and requiring a very large torque for the sealing.
  • the tapered surface 20c does not necessarily have to continue from the lower end of the inner surface 20a to the lower end of the outer surface 20b of the outer ring 20, but may be formed on the side of the inner surface 20a. It is further desired that the lower end of the inner surface 20a of the outer ring 20 is formed in an arcuate shape from the standpoint of improving the resealing performance.
  • the tapered surface 20c has a tapered angle ⁇ (see Fig. 2 ) in a range of 10 to 70 degrees with respect to the horizontal plane. If the tapered angle ⁇ lies outside the above range, the tapered surface 20c fails to exhibit the guide function to a sufficient degree, and the resealing performance may decrease. It is, therefore, desired that the surface between the lower end of the inner surface 20a and the lower end of the outer surface 20b of the outer ring 20 of the liner 17 is tilted to a suitable degree (e.g., at an angle ⁇ ' of about 5 to about 50 degrees with respect to the horizontal plane in Fig.
  • a suitable degree e.g., at an angle ⁇ ' of about 5 to about 50 degrees with respect to the horizontal plane in Fig.
  • the length of protrusion of the inner protruded portion 23 beyond the outer surface of the side wall portion 1b is in a range of 0.03 to 0.65 mm. If the length is too small, it becomes difficult to maintain the sealed structure at the time of opening. If the length is too great, on the other hand, it becomes difficult to attain the resealing.
  • the inner end portion X' thereof (see Fig. 2 ) is positioned in a range of from -5 to +3 mm with the vertex A of the upper curled portion 1a of the open end of the container mouth portion 1 as a reference. If the inner end portion X' of the region X that does not adhere extends inward to an excess degree, the outer ring 20 becomes too flexible. When the cap is opened, therefore, the inner protruded portion 23 does not come in close contact with the side wall portion 1b or the upper curled portion 1a to a sufficient degree, and the sealing may be broken before the bridge 13 is broken.
  • the outer circumferential portion of the liner corresponding to the region X that does not adhere may hang down, and the cap may not often be fitted well to the container mouth portion. If the inner end portion X' of the region X that does not adhere is positioned outwards to an excess degree, on the other hand, the length of the region X that does not adhere becomes too small, the outer ring 20 deforms only to a small degree at the time of draw-forming, and it becomes difficult, for example, to form the inner protruded portion 23.
  • the above liner 17 is obtained by, for example, forming a shell which comprises a top panel and a skirt, dripping a molten resin which is a liner-forming material onto a predetermined portion of the top panel in a state where an adhesive and a parting agent have been applied thereto, and pressing the molten resin.
  • the liner 17 is formed in a shape as shown in Figs. 5 and 6 in order to heighten the opening performance while requiring a decreased torque for the opening.
  • FIGs. 5 and 6 are sectional views illustrating major portions of the liners 17 in a state before the cap 3 is fixed to the container mouth portion 1 by wrap-seaming it.
  • a recessed portion 25 is formed in the surface positioned between the outer ring 20 and the inner ring 21 at a portion positioned on the side of the inner ring 21.
  • a recessed portion 25 is formed in the surface positioned between the outer ring 20 and the inner ring 21 at a portion positioned on the side of the outer ring 20.
  • the recessed portion 25 is crushed, the surface positioned between the outer ring 20 and the inner ring 21 assumes a state of being press-contacted to the upper curled portion 1a of the open end of the container mouth portion 1.
  • the closely contacting force decreases between the above surface and the upper curled portion 1a. This decreases the frictional force that hinders the opening. Accordingly, a decreased torque is required for the opening facilitating the opening.
  • the outer ring 20 formed on the lower side of the region X that does not adhere may be pulled by the metal mold at the time of removing the mold after the forming. Therefore, the outer ring 20 may hang down from a portion corresponding to the recessed portion 25, and may poorly fit to the to the container mouth portion at the time of fitting. From the standpoint of forming, therefore, it is best suited to form the recessed portion 25 in the portion positioned on the side of the inner ring 21 as shown in Fig. 5 to enhance the opening performance.
