Definitions

  • the present invention relates generally to packages and containers for food and beverages and, more particularly, to closures having package opening and resealing features.
  • Paperboard cartons for beverages are generally well known.
  • a familiar type is the milk carton which has a gabled top.
  • a different type of paperboard carton has become available primarily for juices.
  • these aseptic boxes have become popular with children and are known as "juice boxes".
  • the term juice box is somewhat misleading in that the aseptic packages may be used for many other beverages besides juice and even food items such as soups, gravies, and other semi-liquids.
  • the subject of the present invention is separately attachable closures which provide an alternative means of opening and resealing a package such as a juice box.
  • a box like package having a flat top is provided with a scored area which can be broken inwardly to open the package.
  • a closure is fitted over the scored area to assist in opening and so that after opening, the package can be resealed to maintain the freshness of the contents thereof.
  • Previous package closure devices have tended to exhibit some common disadvantages.
  • a structure of some kind is used to penetrate the top surface of the package thereby pushing a flap of the package top down into the package and away from the newly created opening so as not to spring back and partially obstruct the opening.
  • some of the previous devices do not satisfactorily keep the flap from springing back to partially obscure the newly created opening.
  • Another disadvantage of some of the old devices is that upon pouring the fluid out of the box through the newly created opening uneven flow rates result causing fluid to splash through the opening and potentially onto the user causing a mess.
  • Still another object of the present invention is to provide a closure having a built in spout which facilities pouring the contents of a package after opening.
  • Other objects of the present invention are to provide a package closure which is relatively simple in construction and cost effective to produce. It is also an object of the present invention to provide for pouring of the contents of the package at an even flow rate.
  • Yet a further object of the invention is to provide an improved package top preparation over the proposed opening so that when the package top is broken the flap of material does not tend to spring back and partially obscure the newly created opening.
  • a closure for opening and resealing a package includes a base attachable to the top of the package over a scored area and having a rearward portion and a forward portion.
  • the base may be secured very near a pouring edge of the top.
  • a central open area extending longitudinally between the rearward portion and the forward portion is initially and substantially covered by a substantially rigid push-tab pivotally connected to the rearward portion of the base and having a hinged end and a depressable end.
  • the depressable end is deposed over the central opening area of the base prior to opening the package and is pivotally movable through the central opening area to open the package.
  • the central opening area may be pre-cut to open in the same manner as bomb bay doors and may be assisted in such opening by a beak forming an integral part of the depressable end of the push-tab.
  • the hinged end portion of the push-tab includes a vent hole allowing air to enter and resulting in a more even flow rate through a spout formed on a top surface of the base.
  • the spout is formed around at least a forward pouring edge of a raised outer wall surrounding the central opening and a hinged cover is provided on a raised flange of the rearward portion of the base to be rotated over the central opening and to fit tightly thereon to reseal the package.
  • FIGURE 1 is a perspective view of the closure attached to the top of a package according to a preferred embodiment of the present invention
  • FIGURE 2 is a plan view of the closure of FIGURE 1 with a cover rotated to its open position;
  • FIGURE 3 is a perspective view of the closure of FIGURE 2 showing a user's finger on the depressable end of the push-tab;
  • FIGURE 4 is an enlarged section view taken along line 4-4 in FIGURE 1;
  • FIGURE 5 is a section view taken along line 5-5 in FIGURE 3 showing the push-tab in its partially open position
  • FIGURE 6 is a transverse sectional view taken along line 6-6 in FIGURE 5 showing the bomb bay doors of the package top starting to open;
  • FIGURE 7 is a side elevational view showing the push-tab in its full open position and the bomb bay doors fully open;
  • FIGURE 8 is a transverse sectional view taken along line 8-8 in FIGURE 7;
  • FIGURE 9 is a partial plan view of the package top surface showing the scored area.
  • FIGURE 10 is a plan view showing the bottom surface of the closure.
  • the package 22 is a box-like paperboard package which may contain a dispensable fluid, powder, or particulate solid substance.
  • the package 22 may be manufactured from laminated material which is somewhat flexible and tough making it difficult to penetrate.
  • the package 22 may be an aseptic type meaning that it has a sterile inner space 24 which is delimited by an unbroken barrier layer 26 as shown in FIGURE 4.
  • the closure 20 is intended to be applied to the outside of the packing laminate after forming and filling the package 22.
  • the closure is designed to allow opening of the package 22 without its barrier layer 26 having been broken or weakened in advance.
  • the closure 20 of the present invention is particularly suitable for packages that are manufactured from a laminate comprising a carrier layer 28 of fibrous material, e. g. paper, which is covered on both sides by homogenious layers of thermoplastic material.
  • a barrier layer 26 of foil along with a possible sealant layer of thermoplastic material facing the contents of the package 22 may be provided.
  • the carrier (paper) layer 28 and possibly the outer thermoplastic layer can be wholly or partly penetrated while maintaining the barrier layer 26 integrity unbroken, hence maintaining package 22 sterility.
  • the package closure 20 is attached to the package top 30 by any suitable means such as an adhesive 32 applied to a bottom surface 34 of the closure 20 to be attached to the package top 30.
  • adhesives 32 are used consider that the carrier or paper layer 28 of the package 22 may be coated with an outer thermoplastic layer of polyethylene 36.
  • the polyethylene outer layer 36 discourages adhesion.
  • first and second perimeter cuts 38, 40 may be made in the package top 30 region surrounding a central opening area 42 as shown in FIGURE 9.
  • the first and second perimeter cuts 38, 40 may be serrated or perforated cuts which need only penetrate the polyethylene outer layer 36 to allow the adhesive 32 to bond with the underlying carrier or paper layer 28.
  • a series of half cuts 44 may be made in conjunction with the central opening area 42. These half cuts 44 may be to a depth through the package layers down to, but not penetrating, the foil barrier layer 26.
  • first and second arc cuts 52, 54 may be provided at the " forward end region 55 of the central opening area 42. Passing between the arc cuts 52, 54 and running longitudinally along the central opening area 42 of the package top 30 material is a middle cut 56. At the rear end portion 58 of the central opening area 42 first and second notch cuts 60, 62 may be made flanking the middle cut 56.
  • first and second serrated cuts 68, 70 respectively may be provided and function to allow the bomb bay doors 48, 50 formed from the package material to swing (hinge) open and at the same time prevent the doors 48, 50 from separating entirely from the package 22 and falling into the contents of the package 22.
  • the package closure 20 is secured to the package top 30 near a front edge 72 of the package 22 and over the scored area 74 surrounding the central opening area 42.
  • the closure 20 has a base 76 that may be of a substantially rectangular shape having a forward portion 78 and a rearward portion 80.
  • a bottom surface 82 of the base 76 as shown in FIGURE 10 is secured to a top surface 30 of the package 22 by using adhesive 32, for example.
  • a raised outer wall 86 On a top surface 84 of the base 76 as shown in FIGURES 2 and 3 there is formed a raised outer wall 86. Interiorally of the raised wall 86 there is formed a curved inner side wall 88 which at its forward end 90 begins an incline forming a spout 92. A preferred angle of inclination for the spout 92 may be approximately 10°-20°. A pouring edge 94 of the spout 92 may extend just slightly past the forward edge 96 of the base 76.
  • FIGURES 5-8 show the manner in which the package 22 is opened.
  • the barrier layer 26 is not shown for reasons of clarity.
  • a push-tab 98 is formed to initially reside within the inner side wall 88 of the spout 92 and directly over the central opening area 42.
  • the push-tab 98 has a hinged end 100 connected to a rear portion 102 of the inner side wall 88 and may have first and second frangible connections 104, 106 on either side of a depressable end 108 of the push-tab 98 and initially attached to the inner side wall 88.
  • the push tab 98 comprises an upper push surface 110 for the user to exert pressure thereon causing the first and second frangible connections 104, 106 to break, resulting in the depressable end 108 of the push tab 98 rotating down into the package 22 while the hinged end 100 of the push tab 98 remains secured to the inner sidewall 88.
  • a substantially pointed beak 112 may be provided on an under side 114 of the depressable end 108 of the push tab 98 to assist in penetrating the middle cut 56 of the package top 30 material 46.
  • the beak 112 will contact the middle cut 56 which starts the middle cut 56 to split.
  • the push tab 98 is further depressed it will__ continue to separate the package material 46 via the middle cut 56 resulting in the package material 46 splitting into two bomb bay doors 48, 50.
  • the bomb bay doors 48, 50 will stay out away from the central opening area 42 due to the push-tab 98 being positioned between the doors 48,50.
  • the doors 48,50 will also act to keep the push tab 98 extended down and away from the central opening area 42 by exerting a force inward against the push-tab 98.
  • a rear vent hole 118 may be provided in the push tab 98 to allow air to enter the package 22 in a region behind the push-tab 98 as the contents of the package 22 is poured. This will result in a more even flow rate of the package contents. After the package 22 is opened, the user may desire to reseal any remaining, unused contents.
  • a cover 120 is provided.
  • the cover 120 may be formed from the same piece of material as the base 76 and may be integrally hinged to the base 76 via a crease 122 formed at a top edge of a raised flange 124.
  • the raised flange 124 may be formed at the rear edge 126 of the top surface 84 of the base 76.
  • a raised lip 130 may be provided to form a part in the resealing means.
  • An interference fit between the lip 130 and the inner sidewall 88 of the spout 92 offers a complementary sealing means.
  • a rounded leading edge 132 of the cover 120 may be provided to fit over and conceal the spout 92.
  • a step 134 on the rounded leading edge 132 may be provided to offer additional surface area for a user's finger to contact while lifting the cover 120 off the spout 92 when opening the package 22.
  • the entire package closure 20 may be formed in one mold in an injection molding machine as would be known to one of skill in the art.
