Definitions

  • containers and pouches are finding increased utility owing to their simple, cost-efficient construction and adaptability to numerous dispensing and manufacturing operations.
  • the containers and pouches also referred to as “bags” can be made from a single or multi-layered sheets of film that bonded or heat sealed together into any number of shapes and configurations.
  • the use of such bags also allows for greater versatility in selection of materials (both on the inner and outer surfaces that are, respectively speaking, in contact with the dispensed fluid and the ambient environment).
  • fitments penetrate through an aperture or slit formed in one of the layered or single sheets forming the bag. Heat is applied to melt and adhere the layered sheet to the fitment so as to create a heremtic or leak-proof seal. Formations on the inner facing of the fitment may enhance contact, heat conductance, and overall performance of the seal between the bag and the fitment, while a spout or flow channel on the outer facing allows fluid to be dispensed from the bag. It may also be possible to position the fitment between the sheets of the bag or pouch as part of the assembly process for that bag or pouch.
  • Figure 1 A is a side plan view of the various fitments described herein affixed to a bag or pouch, while Figures IB and 1C are, respectively speaking, isolated views of the side and front of the fitment affixed to the bag, similar to the one shown in Fig. 1 A.
  • Figure 2A is a three dimensional, perspective view and Figure 2B a top plan view, both of the fitment of Fig. 1A in isolation and in its closed and unopened state, so that the tamper evident strip remains in its original form.
  • Figure 3A is a three dimensional, perspective view; Figure 3B a top plan view; and Figure 3C a side plan view — all of the fitment of Fig. 1 A in isolation and in its opened and tamper-evidenced state.
  • Figures 4A and 4B are comparative cross-sectional side views (as taken along a central diameter, based upon the view in Fig. 3C) of the fitment of Fig. 1 A in isolation in its closed (Fig. 4A) and opened (Fig. 4B) states.
  • the words “example” and “exemplary” mean an instance or illustration and, as such, are not intended to indicate a key or preferred aspect or embodiment.
  • the word “or” should be construed as inclusive rather an exclusive, unless context suggests otherwise.
  • the phrase “A employs B or C,” includes any combination or permutation (e.g., A employs B; A employs C; or A employs both B and C).
  • the articles “a” and “an” are generally intended to mean “one or more” unless context suggest otherwise.
  • axial and longitudinal may be used synonymously, with both referring to the direction of fluid out of the spout (in cases where the spout is on the top edge of the container, vertically or at an angle when the spout is affixed to a comer of a directional pour bag — see Fig. 1A).
  • radial or transverse are with reference to the axial or longitudinal direction, meaning an orthogonal relationship.
  • top and bottom may simply refer to the spout as it is pictured and oriented in Figs. 3 A and 3C, with the outlet of the spout corresponding to the top and the inlet (formed within the base) at the bottom.
  • the size and spacing of the component presents one of the primary challenges in designing fully functional welded-in fitments.
  • These fitments require an elongated base, sometimes provided with ribs or ridges to dissipate heat experienced by the fitment and the bag when the two are welded together.
  • An aperture is formed through that base and extends upward by way of a cylindrical channel that serves as the spout.
  • fitment designs cannot be arbitrarily expanded or significantly altered.
  • the inclusion of extraneous or excessively large protrusions may increase materials costs.
  • the inventor endeavored to address the shortcomings of conventional welded-in spouts, including the elimination of loose plastic waste and providing a reliable, self-aligning flip top cap that will not interfere with pouring/dispensing.
  • the fitment is now formed in a single molding operation, including appropriate tooling to create/impart the features described herein.
  • the resulting single piece welded-in fitment includes a flip top cap, automatic directional alignment for the pivot of the cap, and a tamper-evident strip that remains affixed to the cap while still providing a clear indication the first time the cap is opened/used.
  • dispensing system 10 includes a pouch-style container 100 with a welded-in fitment 200.
  • the container 100 may be formed by heat sealing and adhering conforming front and back panels 110, 120.
  • An optional bottom panel 130 as well as additional panels (not shown) — may be included to impart a specific shape to the container 100.
  • panels 110, 120 are largely polygonal, while bottom panel 130 has an oval or elliptical shape, although other configurations are possible.
  • the pouch 100 will be configured so that the inventive spout is positioned in a top comer, as shown in Fig. 1 A.
  • the sheets 110, 120, 130 are attached by any conventional means. However, as these sheets are being formed into the final, desired container shape, fitment 200 is situated between two adjoining layers. In this manner, the edges of fitment 200 can be integrally formed within the container 100 itself.
  • One configuration of particular interest is to insert the fitment 200 at a comer 102, with the edges of sheets 110, 120 either clipped or folded inward.
  • the fitment 200 itself also possesses certain features to enhance its attachment to the sheets 110, 120, as will be described below.
  • Heat or adhesive is applied to the joined edges of the sheets 110, 120 and fitment 200 so as to create a fluidic and/or hermetic seal.
  • the sheets 110, 120 may be made of one or more layers of various polymers, with additional layers (e.g., foil(s)) interposed therebetween.
  • additional layers e.g., foil(s)
  • the selection of films is dependent upon the fluids to be provided to the container and the means of sealing the sheets to form the container.
  • fitment 200 includes three functional aspects: an transverse attachment base 220, a longitudinal conduit 240, and a pivoting cap or closure 260.
  • the tamper evident feature 280 is disposed at the interface between the conduit 240 and the cap 260.
  • fitment 200 is formed as single unitary piece, with appropriate tooling or post molding operations imparting the necessary features. In this manner, the need for further assembly and sealing of the dispensing system 10 is largely if not completely eliminated. Also, by providing a flip top cap that is automatically registered so as to pivot orthogonally in comparison to the pouring direction (line 4B-4B in Fig. 4B), inspection and/or cameras to verify positioning of the pivot direction of the cap can also be eliminated.
  • Polymers that are capable of being recycled and/or post-consumer recyclable materials are preferred candidates for forming the fitment 200.
  • Polypropylene, polyethylene, and other similar grades of plastics could be particularly beneficial.
  • the transverse base 220 has a diamond or wedge-like shape when viewed from the top (see Figs. 2B and 3B).
  • the transverse end points 221, 222 may include fins or a transversely aligned flange.
  • the base 220 increases in width from those two points, preferably in regular and symmetrical manner so as to accommodate the outer diameter of the conduit 240.
  • a series of planar ribs 224 are aligned between the top and bottom base plates 223, 225.
  • the ribs 224 will substantially conform to the shape of the plates 223, 225, and ribs 224 help to create a sealing surface along the longitudinal faces of the base 220, with gaps between the ribs providing means of dissipating heat applied to the sheets 110, 120 when the fitment 200 is welded in place.
  • the flanges 221, 222 may extend between the top and bottom plates 223, 225 to improve the structural integrity and/or further accommodate heat dissipation.
  • Conduit 240 includes a hollow tube 242 aligned along axis 4B-4B with an inner diameter that provides passage for fluid.
  • Tube 242 defines a fluid passage or aperture 243 that allows for dispensing when the cap 260 is pivoted to the open position.
  • the outer facing in lower portion 244 of the conduit 240 may have a reduced outer diameter to allow for ribs 224 to be partially formed thereon, as well as reduced thickness for heat dissipation.
  • the upper portion 246 has an increased wall thickness for structural integrity and to accommodate the cap 260 and tamper evident features 280.
  • a cylindrical wall 248 extends upward beyond wall portion 246.
  • the cross sectional or transverse shape of wall 248 is configured to cooperate with a similar wall 268 formed on the pivoting head 262 of cap 260.
  • a sloping ledge 249 is disposed adjacent to the wall 248 on the opposite side from where living hinge 270 connects the cap 260 to the conduit 240.
  • Ledge 249 is configured to accommodate the tamper evident 280, including its attachment hinge 290 and release detent 282, along with the release tab 264 formed on the cap head 262 (see Fig. 2A).
  • Cap or closure 260 is attached to the conduit 240 by way of a living hinge 270.
  • Hinge 270 is integrally formed as part of the molding process, although it may include multiple bending members 271, 272, 273.
  • members 271, 273 are substantially identical and formed to have a different length in comparison to member 272. This allows for the members 271, 272, 273 to extend and remain in a fully opened position, as shown in Figs. 3A and 3B.
  • the thickness of the hinge 270 is configured to withstand repeated opening and closing without detaching from the conduit 240.
  • the cap 260 includes an optional annular skirt 263. Release tab 264 may extend from the wall 286 and/or the skirt 263. When the fitment 200 is first molded, the head 262 is provided in the closed position, but with the tab 263 sandwiched between the ledge surface 249 and the detent 282 on the tamper evident strip 281.
  • Frangible bridges 284 on the strip 281 keep the tamper evident feature 280 secured to the conduit 240 or the wall 248; however, when the cap 260 is pivoted to open the flow passage 243, tab 264 causes the bridges 284 to break away, thereby displacing the strip 281 and providing an indication the first time the cap 260 is opened [0034]
  • a pull tab 286 may be provided at one end of the strip 281 to facilitate or initiate breaking of the bridges 284. In this manner, the strip 281 is pealed away from the fitment 200 (and, more specifically, the conduit 240) so as to allow the tab 264 and the cap head 262 to pivot to the open position.
  • a reinforced hinge or attachment section 290 is formed on the strip 281 at the opposite end from the tab 286.
  • Hinge 290 allows the strip to be bent away from the interface of the conduit 240 and cap 260, so that the dispensing channel 243 can be opened or closed as desired without interference from strip 281.
  • hinge 290 allows the strip 281 to fold away from and/or onto the outer facing of the conduit 240.
  • the hinge is structurally sufficient to remain affixed to the fitment (possibly by having increased thickness in comparison to the bridges 284), thereby eliminating the creation of unwanted plastic parts.
  • the release tab may be affixed to the conduit and the tamper evident strip to the cap.
  • the “sandwiched” arrangement of the tab and the tamper evident strip are flipped, so that the ledge abuts the strip and the tab (which remains immovably fixed in place on the conduit) provides resistance to require removal of the strip before the cap can be pivoted to the open position.
  • the cap 260 can be configured to pivot open at an orthogonal angle in comparison to the intended positioning of the transverse base 220. That is, the diamond-like shape of the transverse base 220 insures that the base will oriented with a preferred dispensing position, as shown in Figs. 1A through 1C.
  • the living hinge 270 is formed to open at an angle so that the open position of the cap 260 does not impede the ability to pour or dispense fluid.
  • that angle will be oriented at about ninety degrees in comparison to the transverse axis defined by the opposing ends 221, 222 of the base 220. This arrangement eliminates problems encountered when a conventional flip top cap is separately attached, in which case an extra processing step is needed to insure the open position for the pivoting action is not impeded.
  • references to coupling in this disclosure are to be understood as encompassing any of the conventional means used in this field. This may take the form of snap- or force fitting of components, although threaded connections, bead-and-groove, and slot-and-flange assemblies could be employed. Adhesive and fasteners could also be used, although such components must be judiciously selected so as to retain the recyclable nature of the assembly.
  • engagement may involve coupling or an abutting relationship.
