Definitions

  • the present invention relates to a packaging system useful for packing fresh roast and ground coffee.
  • the present invention still further relates to a more convenient, lightweight container that provides increased strength per mass unit of plastic for the transport of freshly roast and ground coffee,
  • Packages such as cylindrical cans for containing a particulate product under pressure, such as roast and ground coffee, are representative of various articles to which the present invention is applicable. It is well known in the art that freshly roasted and ground coffee evolutes substantial amounts of oils and gases, such as carbon dioxide, particularly after the roasting and grinding process. Therefore, roast and ground coffee is usually held in storage bins prior to final packing to allow for maximum off gassing of these volatile, natural products. The final coffee product is then placed into a package and subjected to a vacuum packing operation.
  • Vacuum packing the final coffee product results in reduced levels of oxygen in the headspace of the package. This is beneficial, as oxygen reactions are a major factor in the staling of coffee.
  • a common package used in the industry is a cylindrical, tin-plated, and steel stock can. The coffee is first roasted, and then ground, and then vacuum packed within a can, which must be opened with a can opener, common to most households.

  • the present invention is related to a fresh packaging system for roast and ground coffee.
  • the packaging system comprises a container comprising a bottom, a top and a body having an enclosed perimeter between the bottom and the top where the top, bottom, and body together define an interior volume.
  • a flexible closure is removably attached and sealed to the body proximate to the top.
  • the container bottom and body are constructed from a material having a tensile modulus number ranging from at least about 35,000 pounds per square inch (2,381 atm) to at least about 650,000 pounds per square inch (44,230 atm), which provides a top load capacity of at least about 16 pounds (7.3 Kg).
  • the invention is more generally related to a method for the packing of coffee using the container of the present invention.
  • the method steps include filling the container system described above with roast and ground coffee, flushing the container with an inert gas, and, sealing the container with a flexible closure.
  • the invention is also related to an article of manufacture that provides the end user with beneficial coffee aroma characteristics.
  • Roast and ground coffee is contained within the interior volume such that the article of manufacture has an overall coffee aroma value of at least about 5.5. (A method for measuring the overall coffee aroma value is described in the Test Methods section, infra.)
  • At least one purpose of the present invention, inventive method, and article of manufacture is to provide a useful benefit to the user that includes, but is not limited to, providing a roast and pound coffee with a perceived more fresh and aromatic flavor.
  • a container system also provides an easy to use and low cost means of delivery of a roast and ground coffee to an end user.
  • the container has a handle element disposed thereon. More preferably the handle element is integral with the body of the container. This handle element facilitates gripping of the container system by the end user. This gripping is particularly useful for users with small hands or hands in a weakened condition due to illness, disease, or other medical malady.
  • At least one embodiment of the present invention features a one-way valve to release excess pressure built up within the container due to the natural off gas process of roast and ground coffee. It is also believed that changes in external temperature and altitude can also cause the development of pressure internal to the container.
  • the one-way valve is selected to release coffee off gas in excess of a predetermined amount however, remains sealed after such a release, thereby retaining an aromatically pleasing amount of off gassed product within the container.
  • the overcap can comprise a dome, or cavity, that allows positive, outward deformation of the closure due to the pressure build-up within the container.
  • the overcap is preferably air tight and flexible to allow for easy application in manufacture, either with, or without, a closure, and by the end user, after end user removal, of a closure.
  • a flexible overcap can also allow the end user to remove excess air by compressing the dome, thereby releasing excess ambient air from the previously open container (burping).
  • the overcap can also exhibit less flexibility or be inflexible.
  • the overcap also provides for a tight seal against the rim of the container after opening by the end user.
  • the overcap can also optionally allow for stacking several container embodiments when the closure and the dome portion of the overcap are at a point of maximum deflection.
  • the overcap also optionally has a vent to allow for easy removal of vented off gas product trapped between the closure and overcap assemblies, but still allows for "burping.”
  • the overcap can have a rib disposed proximate to and along the perimeter of the overcap defining an inner dome portion and an outer skirt portion.
  • the rib forms a hinge-like structure so that outward deflection of the inner dome portion caused by deflection of the closure due to coffee off gassing causes the rib to act as a cantilever for the skirt portion.
  • outward deflection of the dome portion causes the skirt portion to deflect inwardly on an outer portion of the container wall, resulting hi an improved seal characteristic and improves retaining forces of the overcap with respect to the container.

  • container 11 of the present invention can take any number of shapes and be made of any number of suitable materials.
  • Container 11 generally comprises an open top 12, a closed bottom 13, and a body portion 14.
  • Open top 12, closed bottom 13, and body portion 14 define an inner volume in which a product is contained.
  • closed bottom 13 and body portion 14 are formed from a material having a tensile modulus ranging from at least about 35,000 pounds per square inch (2,381 atm) to at least about 650,000 pounds per square inch (44,230 arm), more preferably from at least about 40,000 pounds per square inch (2,721 atm) to at least about 260,000 pounds per square inch (17,692 atm), and most preferably ranging from at least about 95,000 pounds per square inch (6,464 atm) to at least about 150,000 pounds per square inch (10,207 atm).
  • Tensile modulus is defined as the ratio of stress to strain during the period of elastic deformation (i.e., up to the yield point). It is a measure of the force required to deform the material by a given amount and is thus, a measure of the intrinsic stiffness of the material.
  • bottom portion 13 be disposed concave inwardly, or recessed, towards the inner volume so that undesirable deflections caused by pressure increases within the inner volume are rninimized. If the bottom 13 expands outwardly sufficiently, causing the bottom 13 to concave outwardly, then the container 11 will develop what is generally referred to in the art as "rocker bottom.” That is, if the bottom 13 deflects outwardly so that the container system 10 will not be stable while resting on a flat surface, fresh packaging system 10 will tend to rock back and forth.
  • a plurality of protrusions 40 can be disposed on the closed bottom 13 of container 11 about the longitudinal axis of container 11.
  • protrusions 40 form an oblique angle with the closed bottom 13 of container 11. If the container 11 assumes a cylindrical shape, it is believed that protrusions 40 can be rectilinearly disposed about the diameter of the closed bottom 13 of container 11. However, one of skill in the art would realize that protrusions 40 could be disposed on the closed bottom 13 of container 11 in any geometrical arrangement. Without wishing to be bound by theory, it is believed that protrusions 40 can protrude past the geometry of the closed bottom 13 of container 11 upon an outward deflection of the closed bottom 13 of container 11.
  • container 11 can maintain a stable relationship with other surfaces should "rocker bottom” be realized upon the development of an outward pressure from within container 11.
  • protrusions 40 disposed on closed bottom 13
  • protrusions 40 could be a square, triangular, elliptical, quad-lobe, pentaloid, trapezoidal, arranged in multiply nested configurations, provided in an annular ring about closed bottom 13, and combinations thereof.
  • annular ring 42 can be disposed on closed bottom 13 of container 11.
  • Annular ring 42 could be dimensioned to facilitate nesting, or stacking, of multiple embodiments of containers 11.
  • annular ring 42 could be designed to provide serial stacking of a container 11 onto the overcap 30 of the preceding, or lower, container 11. Without wishing to be bound by theory, it is believed that the facilitation of nesting by the use of annular ring 42 disposed on closed bottom 13 of container 11 provides enhanced structural stability.
  • the closed bottom 13 of container 11 could be designed, in what is known to those of skill in the art, as a quad lobe, or pentaloid. Again, without desiring to be bound by theory, it is believed that such a quad lobe, or pentaloid, design could provide enhanced ability to resist the deformation of closed bottom 13 of container 11 due to internal pressures developed within container 11.
  • container 11 can be cylindrically shaped with substantially smooth sides.
  • Handle portions 15 are respectively formed in container body portion 14 at arcuate positions.
  • a plurality of anti-slip strips 16 can be formed at a predetermined interval within handle portions 15.
  • Handle portions 15 are formed as would be known to one skilled in the art to provide a gripping surface at a most efficacious position to enable users with small hands or debilitating injuries or maladies to grip container portion 11 witibt a minimum of effort. Further, container 11 can be readily grasped by hand due to the configuration described above.
  • container 11 can optionally have a protuberance 17 in the form of a rim like structure disposed at the open end of container 11.
  • Protuberance 17 can provide a surface with which to removably attach closure 18 and provide a locking surface for skirt portion 32 of overcap 30.
  • the protuberance 17 may be continuous as shown in FIG. 1, or it may be discontinuous.
  • a discontinuous protuberance may be formed by a series of tabs or ridges protruding inwardly or outwardly around the open top 12 of the container 11. Also, a continuous protuberance could extend only part-way around the periphery of the open top 12.
  • the closure 18 could be partly sealed to the protuberance and partly sealed to the top rim of the container 11, or sized to have a close, press fit with the container 11.
  • the closure 18 may simply be sealed to the top rim of the container or be sized such that it has a close, press fit with container 11.
  • container 11a can be parallelepiped shaped with' substantially smooth sides.
  • Handle portions 15a are respectively formed in. container body portion 14a at arcuate positions.
  • a plurality of gripping projections 16a are formed at a predetermined interval within handle portions 15a.
  • Corresponding closure 18a and overcap 30a are fitted on container 1 Ia as would be known to one skilled in the art.
  • handle portions 15b can preferably be symmetrical. Without desiring to be bound by theory, it is believed that symmetrical handle portions 15b could prevent inversion of the handle portions 15b upon an increase in pressure from within container lib. It is believed that symmetrically incorporated handle portions 15b provides for the uniform distribution of the internal pressure, developed within container 11, throughout handle portion 15b.
  • handle portions 15b are presented as either parallel to the longitudinal axis of container lib or perpendicular to the longitudinal axis of container 1 Ib.
  • handle portions 15b arranged to provide all component portions of handle portions 15b to be either parallel or perpendicular to the longitudinal axis of container lib, could be less susceptible to bending forces due to internal pressures developed within container lib. This could aid in the prevention of catastrophic failure of the container due to the pressures generated internally to container lib.
  • recessed handle portions 15b could aid in the prevention of an end user supplying extraneous force to the external portions of container lib thereby causing catastrophic failure or deformation of container lib.
  • a handle portion is merely optional.
  • a sticky or slip resistant gripping surface in addition to or in lieu of a handle
  • a slip resistant surface having a relatively high coefficient of friction with respect to a person's hand, for example, or otherwise having a texture that aids gripping can be utilized.
  • a high coefficient of friction could be achieved by use of a light tack adhesive, or a rubber-like material being disposed at portions of the container 11.
  • a gripping texture could be achieved by incorporating a relatively rough surface, such as that of sand paper, on the outside surface of container 11.
  • a container could be shaped to conform to a user's hand.
  • a container having a narrow, oval-shaped cross section could be gripped by a user's hand.
  • a container of virtually any shape beyond those above and those in the Figures can be configured such that it is grippable without the use of a conventional handle. Ih addition, one could simply make a container without any sort of handle or gripping surface, such as shown in FIGS. 8 and 8A.
  • the handle portion could be a part of the overcap, such as the overcap described below.

  • the handle portion can be of a rigid material, such as the same material as the body, and could then extend outwardly and away from the overcap to provide a handle for a consumer to simply grab.
  • the bottom of the container 11 can have a shape having a depression of a suitable size to enable one container to be stacked upon another, wherein the handle portion of the overcap of the lower container can fit within the depression of the bottom of the upper container.
  • container 11 exhibits superior top load strength per mass unit of plastic.
  • filled and capped containers can be safely stacked one upon another without concern that the bottom containers will collapse or be deformed.
  • containers are palletized, by which several containers are stacked in arrays that take on a cubic configuration. On the order of 60 cases, each weighing about 30 pounds (13.6 Kg), can be loaded onto a pallet. Ih certain instances, these pallets can be stacked one upon another. It will be appreciated that the bottommost containers will be subjected to extraordinary columnar forces. Traditionally, polymeric containers are not capable of wimstanding such high column forces.
  • the top load resistance of each container should be at least about 16 pounds (7.3 Kg) when the containers are in an ambient temperature and pressure environment. More preferably, each container should exhibit a top load resistance of at least about 48 pounds (21.8 Kg) in accordance with the present invention.
  • top load resistance is the amount of force an empty container can support prior to the occurance of a deflection parallel to the longitudinal axis of the container of greater than 0.015 inches.

  • top load resistance can be measured using a suitable device such as an Instron, model 550Rl 122, manufactured by Instron, Inc., Canton, Mass.
  • the Instron is operated in a compressive configuration with a 1000 pound load cell and a crosshead speed of 1.0 mch/minute.
  • the load is applied to the container through a platen that is larger than the diameter of the subject container.
  • the body portion 14b of container lib can have at least one region of deflection 43 placed therein to isolate deflection of the container lib due to either pressures internal to container lib or pressures due to forces exerted upon container lib.
  • At least one region of deflection 43 could generally define rectilinear regions of container 1 Ib defined by a cylindrical wall.
  • at least one region of deflection 43 incorporated into body portion 14b could assume any geometry, such as any polygon, round, or non-uniform shape.
  • a purely cylindrical container 1 Ib having a uniform wall thickness throughout, will resist compression due to pressure exerted from within container 1 Ib or external to container lib.
  • any non-uniformities present in a purely cylindrical container lib can cause catastrophic failure upon a differential pressure existing between regions external to container 1 Ib and regions internal to container 1 Ib.
  • the incorporation of at least one region of deflection 43 is believed to allow flexion within the body portion 14b of container lib.
  • body portion 14b can deform uniformly without catastrophic failure and can resist undesirable physical and/or visual effects, such as denting.
  • the volume change incurred by container lib due to internal, or external, pressures works to change the ultimate volume of the container 1 Ib to reduce the differential pressure and thus, forces acting on the container wall.
  • the incorporation of a solid or liquid, or any other substantially incompressible material can provide substantial resistance to the inward deflection of at least one region of deflection 43.
  • the inclusion of a powder such as roast and ground coffee, could provide resistance to the inward deflection of at least one region of deflection 43, thus enabling at least one region of deflection 43 to remain substantially parallel to the longitudinal axis of container 1 Ib and thereby providing an effective increase in the top load capability of container lib.
  • the peelable laminate seal also deflects with external pressure changes further reducing the pressure load on the container.
  • the amount of material to be stored within the container lib may be measured to avoid an excessive amount of "outage.”
  • An "outage” is a free space between the top of the stored material in the container, and the underside of the closure above the coffee.
  • the material's natural tendency to resist inward deflection of the portion of the container lib wall surrounding the material can aid in reducing or eliminating unwanted container wall deformation. Because the portion of the container 1 Ib wall surrounding any outage above the material is more likely to deflect inwardly upon a decrease of pressure within the container, by rilling the container to eliminate or minimize this outage, there are less unsupported portions of the container having less resistance to deflection.
  • reducing the amount of outage by packing the container lib substantially full of material reduces the tendency of unsupported portions of the container to deflect, so that the container lib uniformly responds to differences in pressure.
  • container 1 Ib has at least one region of deflection 43 that can be presented in the form of rectangular panels.
  • the panels have a radius that is greater than the radius of container 1 Ib.
  • the panels are designed to have less resistance to deflection than that of the region of container lib proximate to the rectangular panels. Thus, any movement exhibited by the panels is isolated to the panels and not to any other portion of container lib.
  • the chime should be sufficient to allow container 11 to compress under vacuum by adapting to base volume changes and will improve Hie top loading capability of container 11.
  • the chime should be as small as is practicable as would be known to one of skill in the art.
  • the body portion 14b of container 1 Ib can also have at least one rib 45 incorporated therein. It is believed that at least one rib 45 can assist in the effective management of isolating the movement of at least one panel 43 by positioning at least one rib 45 parallel to the longitudinal axis of container lib and proximate to at least one panel 43 in order to facilitate the rotational movement of at least one panel 43 upon an inward, or outward, deflection of at least one panel 43. Further, it is believed that at least one rib 45 can also provide added structural stability to container lib in at least the addition of top load strength.
  • At least one rib 45 could increase the ability of container lib to withstand added pressure caused by the placement of additional containers or other objects on top of container lib.
  • One of skill in the art would be able to determine the positioning, height, width, depth, and geometry of at least one rib 45 necessary in order to properly effectuate such added structural stability for container 1 Ib.
  • at least one rib 45 could be placed on container 1 Ib to be parallel to the longitudinal axis of container 1 Ib, annular about the horizontal axis of container lib, or be of an interrupted design, either linear or annular to provide the appearance of multiple panels throughout the surface of container 1 Ib.

  • TL static vertical loads
  • container lie can be combined with an overcap (not shown in FIGS. 11 and 12) that can substantially direct the forces exerted by a load to body portion 14 rather than to protuberance 17a. It is believed mat any stress at junction 80 caused by a load positioned on top of container lie having such an overcap disposed theron can be reduced because the deflection of the cantilevered protuberance 17a is restrained. This can result in lower concentrations of stress at junction 80.
  • the flexible and peelable closure 18 or a portion thereof may expand outwardly and contract inwardly, compensating for changes in internal pressure within the container.
  • the expansion and contraction of the flexible closure 18 could compensate for relatively small changes in pressure, while a oneway valve 20 opens to compensate for larger pressure changes.
  • there is no one-way valve and the expansion and contraction of the flexible closure 18 alone is sufficient to compensate for the pressure changes within the container 11.
