Definitions

  • This invention relates to a new and improved spout fitment and plug for closing the same. More particularly the invention relates to a fitment which fits around a hole in a panel of a paperboard carton or around a hole in a flexible container, or the like, such as used for packaging liquid products and powders and to a closure for such fitment.
  • prior fitments have spouts with external threads closed by caps with internal threads. Some fitments are used in conjunction with plastic bag containers, the fitment being integrally welded to the plastic bag. Other prior art fitments are attached to a polymer-coated paperboard container such as a gable-topped half-gallon container.
  • prior art fitments for paperboard cartons include a thin flange which is welded to the surface of the container.
  • the closure includes a foil seal which seals the mouth of the spout and a liner for the cap which serves a resealing function. Attachment to the polymer-coated paperboard is accomplished by welding the flange of the spout to the polymer coating. Upon initial removal, the tamper-evident foil seal is removed and discarded.
  • Fitments of the prior art have a number of deficiencies as compared with the present invention. In the first place, they employ multiple components which increase the cost of the combination very greatly over the simple structure of the present invention. Secondly, assembly is difficult and involves rotary equipment which is difficult to control in practice and is expensive to install. Thirdly, because of the fact that the prior art spouts are externally threaded, the diameter of the opening in the spout is restricted inasmuch as there is only limited space on the panel of the container on which the flange can be located, thereby reducing the diameter of the fitment flange and correspondingly the diameter of the spout. Finally, commercially available fitment-closure combinations have no external tamper-evident features (as contrasted with the internal foil seal of the spout opening).
  • an apparatus comprising in combination, a fitment and a closure therefor, said fitment comprising a spout having an interior and an exterior formed with internal first engagement means, and attachment means for attaching said fitment vicinal an aperture in a container, and said closure comprising a top, a skirt having an interior and an exterior, said skirt depending from said top and formed with external second engagement means engageable with said first engagement means, characterised in that said fitment further comprises diametrically opposed ratchets formed in a top edge of said spout and said closure further comprises a tamper-evident band surrounding and spaced outward of said skirt, said band being connected to said skirt by frangible means and having depending pawls at diametrically spaced positions on an underside of said band which engage the ratchets of said spout to restrain rotation of said closure relative to said fitment so long as said frangible means is intact.
  • One embodiment of the present invention employs a fitment having a spout which is internally threaded and having a flange or other means which is welded or otherwise adhered to the container panel on which the fitment is installed.
  • the closure is an externally threaded plug closure which seals against a membrane on the fitment, which membrane also protects the exposed edge of the hole formed in the container panel.
  • a tamper-evident band on the closure is joined to the closure by a plurality of frangible bridges or the parts may be initially connected by other frangible means. Assembly of the cap on the fitment is preferably performed by a direct axial pushing movement, the threads slipping past each other during the axial movement.
  • the plug and spout may be molded simultaneously in a single cavity in an injection molding machine. Further, as the parts are ejected from the cavity, the threaded plug may be moved axially so that it fits inside the spout and the threads of the spout and plug inter-engage.
  • Fig. 1 is a fragmentary sectional view of a portion of a prior art fitment and closure assembly.
  • Fig. 2 is a side elevational view of a fitment and closure in accordance with the present invention prior to assembly.
  • Fig. 3 is an enlarged fragmentary sectional view through an assembled closure and fitment attached to the panel of a container.
  • Fig. 4 is a top plan view of a fitment.
  • Fig. 5 is a top plan view of a closure.
  • Figs. 6, 7, 8 and 9 are fragmentary sectional views taken substantially along the lines 6--6, 7--7, and 8--8 and 9--9, respectively, of Fig. 5.
  • Fig. 10 is an enlarged vertical sectional view through the structure of Fig. 2.
  • Fig. 11 is a fragmentary sectional view similar to structure to Fig. 10 but angularly rotated to show the integral connection between closure and spout.
  • Figs. 12 and 13 are, respectively, modifications of the structure of Figs. 1 -11, taken substantially along the same lines as Fig. 11.
  • a carton of paperboard coated with a suitable polymer has a panel 21 formed with a hole 22.
  • a fitment 23 Surrounding hole 22 is a fitment 23 having an upstanding spout 24 formed with external threads 26.
  • the lower edge of spout 24 has an external flange 27 which is caused to adhere to the panel 21 by welding, adhesive or other suitable means.
  • the prior art cap 31 has a top disk 32 from which depends a skirt 33 having internal threads 34 mating with the threads 26.
  • the cap 31 may be provided with a liner 36 which functions as a re-closure seal and also with a foil seal 37 which seals against the upper end of the spout 24 and provides tamper-evident features. Once the seal 37 is removed, the liner 36 performs a sealing function on re-closure.
  • Fitment 41 has an upstanding spout 42 formed with a top edge 43 and having internal threads 44.
  • the threads 44 are multiple lead threads, since (as hereinafter described) this balances the gating of the spout (see below descriptions of Figs. 10 and 11).
  • spout is formed with a downward-inward slanted seal membrane 48 which, as shown in Fig. 3, performs a sealing function with the closure as hereinafter appears.
  • Diametrically opposed ratchets 46 are formed in the top edge 43 for the purpose of locking with the tamper-evident band of the closure as hereinafter appears.
  • At the bottom of the fitment is an enlarged peripheral flange 47, the underside of which is caused to adhere to the panel 21.
  • Closure 51 functions as a plug to close the spout 42. It is formed with a top disk 52 having a rounded corner 53 from which depends a skirt 54. The upper portion of skirt 54 is formed with vertical ribs 56 which extend around the corner 53 and partially inward of the disk 52. Ribs 56 are separated by spaces 57. By gripping the ribs 56 the user may turn the closure 51. Midway of the skirt 54 and immediately below the ribs 56 is an external wall 58 and below the wall 58 are threads 59 which mate with the threads 44.
  • a narrow tamper-evident band 61 Surrounding the skirt 54 is a narrow tamper-evident band 61 which is connected to the lower ends of some of the ribs 56 by horizontal frangible bridges 62. At diametrically spaced positions on the under side of band 61 are depending pawls 63 which engage the ratchets 46 of spout 42 to restrain rotation of closure 51 relative to fitment 41 so long as the bridges 62 are intact.
  • One or more tear tabs 64 (here shown as two in number and depending from band 61 immediately outward of pawls 63) are attached to the band 61.
  • the band 61 By pulling the tab 64 outward, the band 61 may be disconnected from the closure 51 and the closure may be turned relative to the fitment since the pawls 63 are out of engagement with the ratchets 46. However, the removal of band 61 or any tearing of the bridges 62 gives evidence of tampering with the contents of the container. To facilitate removal, bridges 62 are omitted in the vicinity of tear tabs 63 (See Figs. 3, 5 and 6)
  • the consumer may turn closure 51 to open and close the container.
  • the end 66 of the skirt 54 seals against the seal member 48 of fitment 41.
  • Figs. 10 and 11 One preferred means for the production of the fitment 41 and closure 51 is shown in Figs. 10 and 11 whereby the two parts may be made simultaneously in a single cavity of a plastic injection mold.
  • the fitment 41 is positioned below the closure 51.
  • the plastic is injected at the top of the closure and the molten plastic extends through the gate 71 into the top of the spout 42. Accordingly the two parts may be molded simultaneously. In order to separate the parts, the gate 71 is fractured.
  • Such fracture may be accomplished merely by pushing axially downward on the closure, the threads 59 slipping over the threads 44. It will be understood, however, that the parts may be molded separately. When molded simultaneously, by proper mold construction, the parts may be assembled before being ejected from the mold.
  • Fig. 12 illustrates an alternate construction.
  • a continuous frangible web connection 76 b connects the plug to the top edge 43 b circumferentially around the parts.
  • the parts may be installed on the container in the condition shown in Fig. 12. So long as the connector 76 b is intact, the consumer is assured that there has been no tampering with the container. At the time of consumption, the user fractures the connection 76 b either by twisting the closure 51 b or other convenient means.
  • the closure 51 b may be installed on the fitment 41 b after part of the contents of the container have been dispensed merely by screwing the closure 51 b into the spout 42 b .
  • the lower end of the fitment 41 b has a downward extending ring 81 which fits inside the hole 22 and is retained therein by an outward extending barb 82 which engages under the panel 21.
  • an outer seal member 83 similar to the seal member 48 b engages the top surface of the panel 21.
  • Fig. 13 shows still another modification.
  • the structure in Fig. 13 is substantially similar to that in Fig. 12 except that the stabilizing seal member 83 of Fig. 12 is omitted. consumer separates the two parts, the closure may be used for reclosure purposes.
  • closure 51 e is joined to the upper edge 43 e of spout 42 e in a frangible, continuous, circumferential tear band 91 which functions as a connection or gate during molding of the parts and further makes the parts in the condition shown in Fig. 17 tamper-evident.
  • circumferential flange 96 extends horizontally out from top disk 52 e beyond the confines of skirt 54e.
  • a pull tab 92 At one or more positions around the circumference of band 91 is a pull tab 92, of limited width, which may extend up above the level of closure top disk 52 e and out beyond the edge of flange 96 so that it is conveniently gripped by the consumer.
  • tab 92 slants downward-inward to join tear band 91. At least one point, tab 92 is connected to the edge of flange 96 by one or more frangible bridges 94 which helps stabilize the tab and also makes additional contribution to tamper-evidency.
  • the flange 47 e may be adhered around a hole in a container with the combination shown in Fig. 17 intact and tamper-evident since as long as bridge 94 and tear band 91 are intact the user cannot obtain access to the contents of the container.
  • the consumer grasps tab 92, breaking bridge 94 and then tear band 91. Closure 51 e is then removed by gripping flange 96.
  • skirt 54 e is inserted in spout 42 e and top 52 e pushed downward. Collar 58 e seals against the inside of spout 42 e and seal member 48 e seals against the outside of skirt 66 e , both sealing with a friction fit.
  • Flange 96 seats on top edge 43 e , limiting downward movement of the closure. The closure 51 e may be removed by gripping flange 96 and replaced repeatedly.
  • fitment 41 f is applied to a container 101 of any convenient type such as one having an external locking bead 102 below top edge 103.
  • Fitment 41 f has an annular top 106 having upward extending spout 42 f .
  • the underside of top 106 has an inner skirt or hollow plug 107 which fits inside the wall of container 101.
  • Outward of plug 107 is a groove 108 which receives edge 103 and beyond groove 108 is a shoulder 109 which fits against the upper outer edge of container wall 101.
  • a peripheral short skirt 111 has an internal bead 112 which locks under bead 102.
  • the closure 51 f is quite similar to that of Figs. 16-18 except that skirt 54 f may be dimensioned to fit tightly within spout 42 f without use of a collar such as collar 58 e of Fig. 17.
  • the lower edge of skirt 54 f is bevelled and is initially connected by frangible connector 76f to the inner edge of the upper end of spout 42 f .
  • closure as shown in Fig. 19 is tamper-evident.
  • the consumer grasps closure 51 f , breaking connector 76 f .
  • closure skirt 54 f if inserted in spout 42 f and pushed down to assume the closed position shown in Fig. 20.
