Definitions

  • This invention relates generally to disposable containers and more particularly to an improved cartridge type dispenser of the type commonly used to contain and dispense food sauces and the like.
  • the sauces are packaged in cartridge type containers and are dispensed incrementally from the containers by trigger operated dispensing guns which are similar to caulking guns.
  • the dispensing gun includes a plunger which is advanced an incremental distance in the container each time an actuating trigger is squeezed.
  • the plunger acts against a closure on one end of the container and pushes the closure into the container toward the opposite or bottom end through which the sauce is dispensed.
  • the bottom end of the cartridge has a dispensing aperture through which the sauce is extruded as the plunger is advanced within the container. In this manner, each time the trigger is squeezed, the sauce is dispensed in a controlled amount which is selected to provide a single serving.
  • the present invention is directed to an improved cartridge type dispenser and especially to a uniquely constructed closure which functions both as a lid and also as a plug for dispensing of the container contents. It is a particularly important feature of the invention that the closure is securely locked on the container rim for service as a lid and yet can be broken away to release it from the container rim when the contents of the container are to be dispensed. This is achieved by providing the closure with a flange that is joined to the wall of the closure along a weakened perforation line. A skirt depends from the flange and includes a locking rib which mechanically interlocks with a down turned lip on the container rim to secure the closure in place.
  • a frangible tear strip on the skirt and flange can be broken in order to initiate tearing of the perforation line so that the skirt flange can be severed from the closure.
  • the closure can thereafter be pushed against the container contents by the plunger of the dispensing gun.
  • the wall of the closure includes a tapered wiping rib which remains in contact with the container wall in order to effectively dispense the container contents without significant leakage past the closure.
  • the corner area of the closure where the wiping rib is located includes an inclined wall section and a plurality of gussets which reinforce the closure and assure that the wiping rib maintains uniform wiping contact against the wall of the container.
  • an indicator arrow for clearly indicating the location of the tear strip and the provision of a knurled surface adjacent to the tear strip in order to facilitate gripping of the closure skirt for breaking the tear strip.
  • numeral 10 generally designates a cartridge type dispenser of the type commonly used in fast service food outlets to hold and dispense mayonnaise based sauces and other sauces and products having a similar consistency.
  • the container 10 has a cylindrical container body 12 formed by a tubular sidewall 14 which may be constructed of any suitable material.
  • the sidewall 14 of the container is constructed of a food grade paperboard coated with polyethylene or another thermoplastic.
  • the container body 12 is formed by rolling the sidewall 14 and suitably sealing the side seam (not shown) formed by the overlapping edge portions of the wall.
  • the container body 12 is provided on its bottom end with a disk of the type shown in U.S. Patent No. 4,432,473 to MacEwen which is incorporated herein by reference.
  • the bottom disk is provided with a dispensing orifice formed by a plurality of slits through the disk which converge at its center.
  • a removable tape is initially applied to the dispensing orifice in order to keep it closed, and the tape can be removed when the contents of the container 10 are to be dispensed.
  • the opposite or upper end of the container body 12 has an outwardly rolled rim 16.
  • the rim 16 is formed by a lip 18 which is an outwardly folded portion on the upper edge of the container wall 14.
  • the lip 18 is located outwardly of the remainder of the container wall and terminates in a bottom edge 20 which is spaced somewhat below the rim 16.
  • the top of the container body 12 is initially covered by a closure or lid which is generally designated by numeral 22.
  • the lid 22 is preferably molded in a single piece and is preferably formed of low density polyvinyl chloride, although other materials can be used.
  • a flat circular disk 24 forms the body of lid 22 and is slightly smaller in diameter than the container body. Extending upwardly and outwardly from the periphery of disk 24 is a short inclined wall 26 which is generally frustoconical in shape.
  • Lid 22 has a sidewall 28 which extends generally upwardly from the top of the inclined wall 26. At the intersection between walls 26 and 28, a thickened wiping rib 30 is formed on the lid.
  • the wiping rib 30 tapers to a point 32 which is in continuous line contact with the inside surface of the container wall 14.
  • a plurality of gussets 34 extend along the inside surface of wall 26 and between disk 24 and wall 28 at a location adjacent the wiping rib 30.
  • the gussets 34 reinforce the corner area of the lid and serve to strengthen and make the lid more rigid in order to maintain the wiping rib 30 in uniform contact with wall 14.
  • the sidewall 28 of the lid fits rather closely within the container body 12, and the top end of wall 28 initially projects above the container rim 16.
  • An annular flange 36 extends outwardly from the top end of wall 28 and is joined to the wall along a weakened perforation line formed by a plurality of spaced apart perforations 38.
  • the perforation line defined by the perforations extends completely around the lid and provides a weakened area along which the flange 36 may be torn away from the wall 28.
  • Flange 36 is horizontal and spans the rim 16.
  • a peripheral skirt 40 extends downwardly from the outer edge of flange 36. Skirt 40 is located on the outside of the container body 12 and fits closely against the outside surface of the lip 18. Skirt 40 has a free edge 42 located well below the bottom edge 20 of the lip. Skirt 40 is provided on its inside surface with a tapered locking rib 44 which is located immediately below lip 18 and which interlocks with edge 20 of the lip. Rib 44 tapers to a point which is located well inwardly of the outside surface of lip 18 in order to mechanically lock lid 22 in place on the top end of container 10. When locked in place on the container, lid 22 covers the top of the container to enclose its contents.
  • a frangible tear strip 46 is formed on skirt 40 and flange 36.
  • the tear strip 46 intersects with the perforation line formed by perforations 38 and serves to facilitate initial tearing of the perforation line.
  • the thickness of strip 46 is approximately .003 inch, and the tear strip is thus readily frangible so that it can easily be torn beginning at the free edge 42 of skirt 40.
  • the tear strip is approximatley .03 inch wide, and the outside surface of skirt 40 is knurled at locations adjacent to the tear strip, as indicated at 48 in Figs. 2 and 3.
  • the knurled surfaces 48 facilitate gripping of skirt 40 with the fingers as the tear strip 46 is being broken.
  • an indicator arrow 50 is provided on the top surface of disk 24 and points directly toward the tear strip 46 in order to provide a clear visual indication of the location of the tear strip on the container.
  • the arrow 50 may be formed by a textured surface.
  • the container 10 serves to hold mayonnaise based sauces and other sauces and products which are to be dispensed incrementally in individual servings.
  • the lid 22 is applied by conventional lid applying equipment.
  • ribs 30 and 44 oppose one another on the inside and outside of the container wall, and the locking rib 44 is mechanically interlocked with lip 18 in order to securely lock the lid in place on the container.
  • the container can be passed through a conventional induction sealer which tack welds flange 36 to the rim 16. It should be noted that the lids can be applied by hand if desired.
  • Lid 22 prevents the contents of the container from spilling during handling and transport.
  • the knurled surface 48 is gripped with the fingers and pulled upwardly in order to break the frangible tear strip 46.
  • skirt 40 tears flange 36 away from wall 28 along the perforation line formed by the perforations 38.
  • flange 36 and skirt 40 20 are detached from the lid and can be discarded.
  • the container can then be inserted into a conventional dispensing gun of the type illustrated and described in the aforementioned patent no. 3,432,473.
  • the plunger 52 of the dispensing gun fits against the top surface of disk 24 and also against the edges of gussets 34.
  • the plunger 52 is advanced an incremental distance, and this pushes lid 22 downwardly in container 10 in order to dispense an incremental amount of the contents through the dispensing outlet at the bottom of the container.
  • the pressure of plunger 52 against the gussets 34 maintains rib 30 and particularly is point 32 in intimate and uniform contact with the inside surface of the container wall 14. Consequently, all of the contents are ultimately dispensed from the container and there is no appreciable leakage past the wiping rib 30.
  • the present invention provides a container in which the lid 22 is securely locked in place to prevent spilling of the container contents during transport and handling of the container.
  • the flange 36 and skirt 40 can be quickly and easily severed from the lid in order to unlock it from the container and release it so that it can be pushed downwardly by plunger 52 into the interior of the container during dispensing of its contents.
