Definitions

  • This invention relates to a new and improved closure cap of the press-on type. More specifically, this invention relates to improvements in closure caps of the type which have gasket means to form threads on application to a container finish. Subsequent removal may be accomplished by rotation or prying off at the option of the user.
  • the present invention consists of a metal closure shell of conventional shape having a top panel and depending skirt portion, and if desired, a gasket groove or channel at the.intersection of the two portions.
  • Compressible gasket material is disposed around the inner peripheral portion of the skirt and fills the gasket channel, and if desired, may extend inwardly onto the underside of the top panel.
  • the gasket material is molded to a unique shape, including a plurality of radially directed ribs.
  • the ribs provide for a more even application of the closure to the container finish due to the reduced amount of material to be displaced, especially when contrasted with caps having a lining of gasket material with the continuous inner circumferential surface formed to an inside diameter equalling that of the libs.
  • the ribs permit hot and cold application of the closure cap to the container finish, and lastly, when they comprise between approximately 30% to 70% of the internal circumferential surface area of the gasket material lining the skirt, a materially increased resistance to the loss of the hermetic seal by impact is experienced.
  • FIG. 1 is a perspective View looking down into the interior of an inverted closure cap of the present invention
  • FIG. 2 is an enlarged diametric cross section of the closure cap of FIG. l;
  • FIG. 3 is an enlarged cross sectional view of the closure cap of FIG. 2 at the initial stage of application to a known form of container finish which is also shown in section;
  • FIG. 4 is a view similar to FIG. 3 with the closure cap in an intermediate stage of application;
  • FIG. 5 is the cap of FIGS. 3 and 4 in the finally applied position
  • FIG. 6 is a diametric cross section of the cap of FIG. 5 after removal from the container finish of FIGS. 3-5;
  • FIG. 7 is an enlarged cross sectional view of the lefthand portion of FIG. 6 illustrating the reformation of the gasket material
  • FIG. 8 is a further enlarged cross sectional view of the right-hand portion of the closure cap of FIG. 6 llustrating the reformation of the gasket material at the center of a rib;
  • FIG. 9 is an enlarged fragmentary cross sectional View taken generally along the lines 9-9 of FIG. 2;
  • FIG. 10 is a view taken along the lines 10-10 of FIG. 8 generally showing the shape of the ribs after the threads have been formed.
  • a closure cap of the present invention is shown at 10 and includes a shell 11 and gasket 12.
  • the shell 11 is inverted, illustrating a cup-like shape formed by a top panel 13 which is bordered by a cylindrical skirt 14 projecting axially from the periphery of the top panel 13.
  • the lower end of the skirt 14 may be outwardly flared as: at 15 and curled into a reinforcing bead 16 of conventional design.
  • the material lining the shell 11 and forming the gasket 12 is disposed around the inner circumferential wall surface 17 of the skirt 14 and extends axially from ⁇ the flare 15 to the top panel 13.
  • a gasket groove or channel 18, formed by the skirt 14 and a shoulder 20 is also filled with the gasket material which may extend inwardly beyond the shoulder 20 and terminate on the depressed center panel .31, or if desired, may cover the entire ⁇ center panel 21. If needed, a suitable coating (not shown) may be provided on the interior of the shell to protect the metal and enhance the adherence of the gasket material to the skirt 14 and top panel 13.
  • the gasket 12 is molded to the shape shown in FIGS. 2 and 3 within the shell 11 to provide a thread forming surface area 22, a side sealing surface area 23 and a top sealing surface area 24.
  • the thread forming surface area 22 is disposed at an angle of about 6 to thecylindrical Wall forming the skirt 14. About two-thirds of the Way up the skirt, the thread forming surface 22 intersects the side sealing surface which is formed at an angle of about 20 to the skirt.
  • the top sealing surface 24 of the gasket 12 is disposed generally at right angles to the skirt 14.
  • each rib 25 is formed with a finish engaging surface 26 which is disposed at an angle of about 10 to the skirt -14 or central axis of the shell, which angle is between that of the thread forming and side sealing surfaces. While the ribs appear to have a diamond configuration when viewed in front elevation, it is apparent from the cross sectional View of FIG'. 9 that before application the surface 26 is generally arcuate when viewed in cross section.
  • the ribs 25 are spaced circumferentially around the inner lperiphery of the closure cap and are appropriately dimensioned, as will be seen, to engage the helical thread on a container finish of known form. It has been found that tapered ribs will provide for more even application of the closure cap to the container finish due to the reeuted amount of material to be displaced. When capping at the usual high speeds, cocking or uneven application cannot be tolerated.
  • a typical glass container 30 of the type briefly described above is fragmentarily illustrated in cross section.
  • the container 3i) includes a finish 31 having a circumferential bead 32 above which is provided a generally cylindrical wall 33.
  • the wall 33 forms the minor diameter of a helical thread 34 which is integrally embossed on the finish 31.
  • the helical thread 34 may comprise one continuous turn with the ends overlapping slightly as shown, or may consist of a discontinuous helical thread or the like.
  • the former type of finish is a standard in the industry and is particularly adapted to receive baby nipple adapters or the like.
  • the problem of cooking encountered during application of caps having the gasket material formed to a continuous inner circumferential surface were solved through the provision of the ribs 25, the number of which may be varied down to as low as about of the total inner circumferential area of the gasket 12 without adversely affecting the capping speed.
  • the ribs 2S assist the cap in being properly and evenly located on the finish during the press-on type application because they reduce the total amount of gasket material to be displaced initially and during cap application.
  • the lower end of the finish engaging surface 26 of the rib 25 touches the threads initially while the balance of the gasket remains spaced thus minimizing the amount of gasket material to be deformed.
  • the closure cap 10 is in an intermediate stage of application such that the top of the thread 34 has begun to deform the thread forming surface 22 in the gasket 12. Obviously, greater deformation occurs in the area of each of the ribs 25 causing the material to begin expansion into the void or space above and below the thread 34.
  • the finish engaging surface 26 on the rib 25 engages the lower end of the thread 24 to assist in maintaining the cap properly oriented relative to the finish throughout application.
  • the continuous thread 34 is embedded in the thread forming surface 22 of the gasket material proper as well as being embedded in the finish engaging surface 26 of the radially projecting ribs 25.
  • the embedment will be slightly greater than at the lower portion as is evident in the left-hand portion of FIG. 5.
  • the additional gasket material provided by the ribs 2S assists in forming a radially deeper thread especially along the top of the helical thread 34 to provide better cam off properties facilitating easy removal of the closure cap 1t) by rotation relative to tlie container 30.
  • a related but additive feature is the increased ability of the newly formed threads to hold the cap properly located while .the package is cooling so that a vacuum may be formed to permit atmospheric pressure to assist in holding the closure cap 16 to the container 30 until the package is opened. It has been found that by controlling the number of ribs, the hermetic security of the package can be increased. Shock resistance can be increased when the ribs 25 occupy somewhere between 30% to 70% of the total circumferential side surface area, excluding of course, the gasket material which cooperates with the top of the nish 31. In practice, on a closure cap for a 40 nim. finish, this is equivalent to between about l2 to about 20 of the ribs 25. Obviously, this number will be adjusted depending upon the dimensions of the container finish, size of ribs or changes in other variables.
  • the gasket material used in the present closure cap may consist of a puffed plastisol of known type and may be capped at room temperature or under heated conditions. Ordinarily, the closure operation is greatly facilitated by the use of heat at the time of application to the container finish. As the material cools the thread impressions formed in the ribs and thread forming surface become sufficiently rigid to permit removal of the closure cap 10 by rotation, yet the gasket material is still sufliciently resilient to permit the cap to be pried olif by known methods, this being desirable where a large number of caps are to be rapidly removed. In the case of cold application, the cold flow properties of the gasket material serves to provide the thread forming function.
  • the preferred material as noted is a puffed or foamed plastisol composition, but other plastonieric compositions having requisite resilience and flow and set properties are also suitable.
  • molding temperatures will be of the order of 325 F. to about 425 F.
  • a final heat treatment of about 350 F.-420 F. for a period of 30 to 200 seconds finally fiuxes the plastomeric material by completely dissolving the resin particles in the plasticizer in a well known manner. Obviously, these temperatures and times will vary with type and amount of compound used.
  • the thread 40 formed in the gasket 12 through press-on application of the closure cap 10 is self-maintaining upon removal from the container finish 31.
  • the upper edge 41 of the thread 40 extends over the top of the thread 34 to provide increased thread depthor surface area, especially in the regions of the ribs 25 to reduce the force per unit area during cap removal thus reducing shear modulus requirements of the material.
  • the taper of the gasket material 12 as well as the taper of the ribs 25 insures that a greater amount of gasket material will be present at the top margin of the thread as opposed to the lower margin at the same location, however, at the lower end of the thread 40, as shown in section at the right-hand portion of FIG. 6, a sufficient amount of gasket material is present to overlie the threads to provide good cam off properties even at the lower ends of the threads.
  • the lower portion of the thread makes an impression in the thread forming surface 22 adjacent the lower extremity of the skirt 14.
  • the over-all depth of the thread increases, as is evident in both FIGS. 7 and 8, as the helix advances towards the top panel 13.
  • the thread depth is greater than in the compound adjacent each side of the rib.
  • the increase in thread depth provides a greater cam off surface area and also greater holding power on application. rThe reduced amount of gasket material to be displaced during the initial stages of application to a container finish, permits the cap to be properly oriented and easily located on the container finish before it is pushed home or to the fully applied position as shown in FIG. 5.
  • the novel package formed by applying the closure cap of the present invention to a known form ⁇ of container finish provides the advantage of permitting press-on application and removal by rotation or prying off with reapplication possible in either case.
  • the ribs add to package security when they comprise from about 2.0% up to about 60% of the gasket area. Also, hot and cold application can be accomplished with the present cap with better cam off properties. Obviously, other advantages in the form of expedient application and minimum expense in capping are also present.
  • a package comprising a closure cap and container, said container including a finish portion having a continuous helical thread embossed thereon, said closure cap including a top panel and a skirt, a com-pressible gasket material lining an inner peripheral portion of said skirt and extending radially inward over at least a part of said top panel, said gasket material providing a radially facing inner circumferential surface for engagement with said continuous thread on said container finish when said cap is applied thereto, said radially facing inner circumferential surface of said gasket material having a plurality of circumferentially spaced and radially raised ribs engaging said continuous threads in advance of the remainder o-f said gasket during capping to assist in locating said cap at application and said ribs being tapered radially inwardly in a direction towards the top panel to provide increased radial thickness of said gasket material adjacent a top portion of said container finish.
