Definitions

  • This invention relates to an article carrier of the wraparound type and, more particularly, to a carrier for packaging a plurality of articles in a row having an improved thread-and-punch type lock for interlocking overlapping panels of the carrier.
  • U.S. Patent 3,374,938 to Pierce, Jr. is directed to an article carrier of the wraparound type in which the bottom panels are secured in overlapping relation.
  • a plurality of tongues on one of the bottom panels is threaded into corresponding transversely elongated apertures in the other of the bottom panels.
  • Each of the tongues has a locking tab longitudinally aligned therewith for disposition in the same transversely elongated aperture as the tongue.
  • the tab is punched through the aperture by the packaging machine to lock the panels together.
  • Each of the tongues is threaded in the position to have an edge to edge engagement with a transverse locating edge of the corresponding aperture.
  • Each locking tab after being punched into position, also has an edge to edge engagement with the opposite transverse edge of the aperture to lock the overlapping bottom panels of the elongated blank to form the carrier.
  • the carrier of the present invention is an improvement over the prior art Pierce carrier in that it does establish and retain better edge to edge relation along two substantially parallel, transversely elongated slits, and provides lock protection by providing a protector strap which overlies the tab along the interior of the carrier.
  • U.S. Patent 4,200,220 to Ganz is also part of the prior art.
  • This patent is also directed to an article carrier of the wraparound type in which the bottom panels are secured in overlapping relation.
  • the tongues on one of the bottom panels are threaded into corresponding transversely elongated slits in the other of the bottom panels, but this is done only after doubling over each bottom panel with a fold of 180°.
  • Each of the tongues has a tab longitudinally aligned therewith for disposition in a cooperating elongated slit on the opposite bottom panel.
  • the tab lies in a plane substantially perpendicular to the plane in which the tongue lies.
  • This carton requires complicated machinery to perform the doubling over folds and threading of the tongue and tab. Also, the tab which extends vertically into the interior of the carton is susceptible to damage by the articles within the carrier and in a damaged state, likely to slip back through the receiving slit. The doubling feature greatly increases the cost of the carrier due to the increase in paperboard required.
  • the lock should have a tab and tongue extending in opposite directions within substantially the same plane, thereby providing a secure edge to edge engagement, and including a protective arrangement for improved lock retention and for additional strength and support.
  • Another object of this invention is to provide a wraparound carrier which minimizes paperboard requirement and thus costs less to manufacture.
  • Another object of this invention is to provide a lock structure in a wraparound carrier including spaced locking slits to receive and retain a locking unit with protection against inadvertent release.
  • Still another object of this invention is to provide a lock in a carrier having specially formed slits for the purpose indicated to provide improved lock performance and additional security.
  • Still another object of this invention is to provide a wraparound carrier with an improved lock as described that is'easy to erect on existing high-speed equipment.
  • an improved wraparound carrier for the packaging of a plurality of articles in at least a single row.
  • the carrier includes an elongated blank having fold lines to form panels including closure panels designed to overlap when applied to the articles to be packaged.
  • One of the closure panels has a plurality of locking units spaced from each other transversely of the blank, each including a tongue and a locking tab in' longitudinal line with each tongue and adjacent thereto.
  • the other of the closure panels includes a plurality of two substantially parallel, transversely elongated slits for receiving each locking unit when the closure panels are in proper overlapping relation. Disposed between these slits is closure panel material forming a protector strap.
  • each tongue When properly locked, each tongue is inserted through the corresponding slit furthest from the edge of the second closure panel.
  • the locking tab is then punched in the slit nearest the edge of this closure panel so as to overlie this closure panel and create edge to edge engagement.
  • the protector strap overlies the tab along the interior of the carrier to hold the tab in locked engagement and to provide extra strength.
  • the tongue and locking tab extending in opposing directions and engaging the locating edge and the locking edge of the ⁇ two slits, respectively, are within the same plane and thus provide the carrier with secure edge to edge engagement between the closure panels. Since the tab does not extend vertically up into the carrier, but instead is positively held down by the protector strap, it is protected from being inadvertently damaged and dislodged by the articles therein. Also, the positive edge to edge engagement prevents either the threaded tongue or the punched in tab from slipping through its slit. Improved lock retention that in turn improves carton reliability is the favorable result obtained.
  • the invention employs two, substantially parallel, transversely elongated slits, and a protector strap in between, the need to strip the trim from a hole or aperture, as often required in the prior art is avoided.
  • This feature coupled with reduced paperboard required with respect to some designs, substantially reduces the cost incurred by the manufacturer.
  • the present invention provides convenient mechanical threading and punching for easy adaptation to high speed, state of the art automation techniques and machines.
  • the protector strap which overlies the tab along the interior of the carrier to hold the tab in locked engagement also increases the strength of the panel in the lock area.
  • the protector strap connected by bridges at each end span the lock area. This strap provides an article carrier of increased strength over those in the prior art even after exposure to refrigerated conditions wherein the paper absorbs moisture and loses stiffness.
  • the article carrier 10 is formed from an elongated blank 12(see Figure 1) of a suitable foldable sheet material such as paperboard, for example.
  • the elongated blank 12 has a single top panel 14 with circular apertures 13 cut therein to accommodate the necks of the bottles 11.
  • Side panels 16 are articulated or hingedly joined to opposite sides of the top panel 14 along a pair of top fold lines 15.
  • the side panels 16 are designed to be substantially vertical in the completed article carrier 10, as shown in Figure 2.
  • a bottom or closure panel 21 is articulated or hingedly joined to one of the side panels 16 along a fold line 22(see top of Figure 2).
  • Another bottom or closure panel 23 is articulated or hingedly joined to the other of the side panels 16 by fold line 24.
  • the bottom panel 21 has a plurality of transversely spaced lock units each including a tongue 25(three shown in Figure 1) with the number of tongues 25 preferably being equal to the number of bottles 11 (see Figure 2) in each of the rows.
  • the tongues 25(see Figure 1) are spaced from each other by recessed edge portions 26 between the tongues.
  • the outer ends of the edge along the panel 21 adjacent the end tongues 25 are formed by an edge extension 30 and connect to longitudinal side edges 31 and 32 of the elongated blank 12.
  • the bottom panel 21 thus has its terminal edge defined by the edges of the tongues 25, the recessed edge portions 26 and the connecting edge extensions 30.
  • the bottom panel 23 has a plurality of pairs of adjacent, substantially parallel, transversely elongated slits for receiving the corresponding locking units when the closure panels are in proper overlapping relation.
  • First transversely elongated slits 33 are formed adjacent the terminal edge 34 of the bottom panel 23, between the terminal edge 34 and second transversely elongated slits 35.
  • the bottom panel material disposed between the first slits 33 and second slits 35 forms protector strap 38.
  • the first slit 33 may include relief extensions 33a at each end thereof. These extensions 33a preferably are at an angle of about 135" from the slit 33.
  • Second transversely elongated slits 35 may include relief slits 35a at each end thereof. These relief slits 35a extend toward the first transversely elongated slits 33 at an angle of approximately 90° from the second transversely elongated slits 35. The corner is rounded to minimize the tendency to tear the paperboard.
  • the relief extensions 33a and relief slits 35a further define the bridges at the ends of the protector strap 38.
  • the bridges(see Figures 1 and 4) have a length substantially equal to the combined length of relief extensions 33a and slits 35a to insure maximum strength while at the same time providing the required relief for ease of engaging the lock units.
  • Each of the tongues 25 is threadable into one of the transversely elongated slits 35 when the bottom or closure panels 21 and 23 are in overlapping relation.
  • Each tongue 25 overlies the inner transverse edge of the corresponding slit 35 so as to have a relatively large area of overlapping cbntact( Figure 4A). As can be seen, the edge of the slit 35 forms a locating edge for the locking unit.
  • the bottom panel 21 has a set of locking tabs, designated by the reference numeral 39; a single locking tab being longitudinally aligned with each of the tongues 25.
  • the locking tabs 39 are formed through slitting the bottom panel 21 and may be bifurcated, as shown in the preferred embodiment.
  • the locking tabs 39 and the tongues 25 together form the locking unit, generally designated by the reference numeral 40( Figures 1 and 3).
  • the locking tab 39 is then punched(from below) through the transversely elongated slit 33 so that the locking tab 39 directly overlies closure panel 23 thereby providing edge to edge engagement with the transverse edge (see Figure 4B). Further, the protector strap 38 overlies the tab 39 to hold the tab in locked engagement while providing additional strength and support to the carrier 10.
  • Figure 4C A fragmentary view of the fully threaded article carrier 10 from below is shown in Figure 4C.
  • the elongated blank 12 is first placed over the necks of the bottles 11.
  • the side panels 16 are folded down the sides.
  • the bottom panels 21 and 23 are folded under the bottoms of the bottles 11.
  • the tongues 25 are threaded into the trans- versely elongated slits 35 and the locking tabs 39 are punched into the longitudinally aligned transversely elongated slits 33 by forcing with punching wheels(not shown) past the transverse edge of the slits 33.
  • the locking arrangement of the present invention enables a relatively large edge to edge locating and lock- ing engagement in a transverse direction.
  • a firm, secure and protected locking engagement safe against inadvertent release is provided.
  • the improved performance is obtained without any increase in paperboard in the blank over that used in the original Pierce carrier shown in the previous Certipak patent cited above, and considerably less than that used in later patents seeking to improve the strength.
  • the lock structure of the present invention also provides convenient mechanical threading and punching for adaptation with state of the art machines and improved automation techniques.
  • the blank could be provided with slits having different shapes and configurations.
  • the edges of the blank may not necessarily be as shown-but could include other shapes and separate angled portions.
  • the embodiment was chosen and described to provide the best illustration of the principles of the invention and its practical application to thereby enable one of ordinary skill in the art to utilize the invention in various embodiments and with various modifications as are suited to the - particular use contemplated. Also such modifications and variations are within the scope of the invention as determined by the appended claims when interpreted in accordance with the breadth to which they are fairly, legally and equitably.entitled.
