Definitions

  • ABSTRACT A container for packaging comminuted dry products or the like is provided which has a self-contained reclosable pull-out pouring spout.
  • the container is formed from a single blank of sheet material and, when initially setup, forms a sift-proof container having a flat top and with the pouring spout in a retracted closed position.
  • a folding container for a comminuted dry product which includes a self-contained reclosable pull-out pouring spout formed in the top portion of the container.
  • the container is formed from a single blank of sheet material and comprises side and end walls having closure flaps foldably connected to the upper end limits of the container walls.
  • the closure flaps have adjacent ends thereof foldably connected.
  • the closure flap connected to one end wall and the adjacent portions of the closure flaps connected to the side walls form the components of the pouring spout.
  • the one end wall closure flap includes a first triangular section having one side edge thereof connected to and substantially coextensive with the upper end limit of the one end wall, and second triangular sections disposed on opposite sides of the first section and foldably connected to the remaining side edges of the first section.
  • a second side edge of each second section is foldably connected to the adjacent end of the closure fap connected to the upper end limit of a side wall.
  • One of the closure flaps connected to a side wall is adapted to overlap the other closure flap, when the top of the container is closed, and substantially span the distance be tween the side walls.
  • the overlapping closure flap is provided with a tear line in spaced substantially parallel relation with the folding axis of the closure flap. The tear line extends from the end of the closure flap connected to one of the triangular second sections.
  • the free edge of one of the closure flap triangular second sections is provided with a tab which is substantially coextensive with the free edge and is adapted to be sandwiched between the closure flap connected to one side wall and the other triangular second section when the pouring spout is folded into a closed retracted position.
  • FIG. I is a perspective view of one form of the improved container shown in an initially closed condition.
  • FIG. 2 is an enlarged fragmentary perspective top view of the container of FIG. 1 showing the portion thereof incorporating the pouring spout in its initially closed retracted position.
  • FIG. 3 is similar to FIG. 2, but showing the pouring spout pulled out.
  • FIG. 4 is a fragmentary sectional view taken along line 4-4 of FIG. 2.
  • FIG. 4a is a fragmentary sectional view taken along line 4a-a of FIG. 2.
  • FIG. 5 is a plan view of the blank for the container of FIG. 1.
  • FIG. 6 is a fragmentary plan view of the bottomforming portion of a modified blank.
  • FIGS. 7-16 are fragmentary perspective views showing various Stages of forming the closed top of the container of FIG. 1.
  • FIG. 11 is a fragmentary end elevational view of the container of FIG. 1 and showing the pouring spout in its initially closed position.
  • FIG. 12 is a fragmentary perspective view of the top of the container showing the pouring spout in a reclosed position.
  • FIG. I an improved, rectangularly shaped foldable container or carton l is shown which is provided with a substantially flat top la which incorporates the reclosable pull-out spout, to be described more fully hereinafter.
  • the container 1 is particularly suited for accommodating comminuted dry products, such as granulated detergents, grass seed, ice-melting salt, fertilizer, cake mixes, etc., wherein the entire contents of the container is not normally dispensed at one time.
  • the size and shape of the container and the location of the pouring'spout thereon may vary from that shown without departing from the scope of the invention.
  • the container 1, in the illustrated embodiment, is formed from a blank of sheet material such as paperboard or the like, see FIG. 5.
  • the type of sheet material to be used in forming the blank will depend upon the characteristics of the product to be accommodated in the container.
  • the blank includes panels A, B, C and D which are arranged in side-by-side relation and are interconnected along their elongated edges by foldlines l3, l4, and 15, respectively.
  • Panels A and C define the side walls and panels B and D define the end walls when the blank is setup to form the container 1.
  • a glue flap E may be connected by foldline 16 to the outer edge of panel I).
  • closure flaps 8 and 9 Connected by foldlines 21 and 22 to the upper edge of side wall panels A and C, respectively, are closure flaps 8 and 9.
  • flap 9 When the top 1a of container 1 is formed, as seen in FIG. I, flap 9 will be exposed and overlap flap 8 and be adhesively secured thereto.
  • Each flap 8 and 9 is substantially coextensive with the upper edge of the side wall panel to which it is foldably connected.
  • the length of flap 9 mea sured perpendicular to foldline 22 is substantially equal to the spacing between foldlines l3 and 14 connecting end wall panel B to side wall panels A and C.
  • closure flap SP is provided with a pair of foldlines 2 which converge from the corners of the flap so as to define a triangular area I.
  • the angle ineluded by foldlines 2 is bisected by a tear line 3 which extends to the adjacent end of the flap 9.
  • segment 5' or 5 is centrally disposed with respect to the remaining segments 4' and 6' or 4 and 6 and has the lower side thereof defined by foldline 23 or 24.
  • Corresponding sides of segment 4' and 6' or 4 and 6 are foldably connected to the remaining two sides of triangular segment 5' or 5.
  • a second side 6a of segment 6 is foldably connected to the lower portion'of the end 9a of flap 9.
  • the foldline connection constitutes an extension of foldline 14.
  • the remaining side 6b of segment 6 is formed by a cut and is substantially coaxial with tear line 3 formed in the triangular areal of flap 9.
  • segment 6' is connected to the opposite end 9b of the flap 9.
  • Triangular segment 4 has a second side 4 a thereof foldably connected to an adjacent end of closure flap 8.
  • the foldline connection between flap 8 and segment 4 constitutes an extension of foldline 13 which joins panels A and B.
  • the remaining side of segment 4 is provided with a tab or tongue 4T which projects beyond the side edge 6b of segment 6, see FIG. 5. If desired, however, such tab 4T may be formed on the edge 6b of segment 6 rather than as shown in the drawings. The function of tab 4T, in either case, will be described more fully hereinafter.
  • Flap 8 has a triangular segment 7 formed at the end thereof which is foldably connected to and is substantially a mirror image of triangular segment 4. Segment 7, in turn, is substantially the same shape as half 7 of the triangular area I defined by the tear line 3 so that, when flaps 8 and 9 are in overlapping realtion, area 7 will be in superposed relation with respect to segment 7 and be adhesively secured thereto.
  • Segments 4, 5', and 6' are similarly arranged, except that segment 4 has one side thereof foldably connected to an adjacent portion of glue flap E. The remaining side of segment 4' is provided with a projecting tab 4'T.
  • foldlines 21, 24, 22, and 23 are coaxially aligned and are disposed perpendicular to foldlines 13, 14, 15, and 16. Furthermore, the length of flap 8 measured normal to foldline 21 is approximately one half the length of flap 9.
  • Foldably connected to the lower edge of panels A-D may be conventional bottom closure flaps l2, 110, II, and 25, respectively.
  • flap ll would be exposed and overlie and be adhesively secured to flap I2 and the latter, in turn,.would be adhesively secured to and overlap flaps 1.6 and 25.
  • flaps 8B and 9B and triangular segments 43, 5B, and 6B; and 4B, 5B, and 68' might be substituted for the bottom closure flap 12, ll, 10 and 25, respectively, see FIG. 6.
  • a projecting tab 4TB or 4TB would be formed on either triangular segment 48, 4B, 6B, or 68'.
  • the blank will initially be folded so that glue flap E will be secured by adhesive or hot melt to the inner surface of panel A.
  • the blank in such a state, assumes a collapsed tubular condition and normally remains in such a condition until the container is to be setup for filling.
  • the collapsed tubular blank is squared so as to form a tube whereby panels A and C and panels B and D are disposed in opposed spaced relation and define the cavity in which the product is to be deposited.
  • the bottom has already been formed and that the product has been deposited within the cavity.
  • each projecting tab will become wedged or sandwiched between the underside of the outside flap 9 and the segment 6 or 6', see FIGS. d and 4a. Because tab 4T extends a substantial distance beyond tear line 3 and the edge 6b of segment 6, the tab 4T prevents leakage of the product in the vicinity of the tear line 3 and edge 6b, notwithstanding, that the disposition of said tear line and edge might not be in substantial vertical alignment.
  • manufacturing tolerances with respect to the location of the tear line 3 and edge 6b of the segment 6, may be less exacting than might otherwise be the case and still enable the container to be substantially leak-proof in the vicinity of the retracted pouring spout when the container is in its initially closed position.
  • each tab may be rounded or bevelled, as shown.
  • edge 6b of segment 6 does not engage in abutting relation any portion of segment 4 as is the case in various prior art structures (e.g., in U.S. Pat. No. 3,120,335 the cut edges of the fold-back panels 60 and 61, FIGS. 7-9 assume an abutting relation).
  • sliding of the tab 4T into pocket P is a smooth and unobstructed operation permitting closing of the top to be readily accomplished either manually or by high speed automatic or semi-automatic folding apparatus.
  • the tab is formed on the triangular segment 6 rather than segment 4, as shown, the aforedescribed folding procedure is followed, except that the tab is inserted into a V-shaped pocket formed between closure flap 8 and the folded back segment 4. In most instances, it is preferred that the tab 4T be formed on segment 4 rather than segment 6.
  • the top 1a assumes a substantially flat position, thereby facilitating stacking of a plurality of loaded containers for storage or shipping.
  • a fingertip is inserted under segment 6 and in substantial vertical alignment with tear line 3.
  • flap 9 will tear along tear line 3 while at the same time tab 4T will be withdrawn from the pocket P because the tab is not adhesively or otherwise secured to the underside of flap 9 or segment 6 or flap 8 or segment 4, whichever the case may be.
  • the foldlines 2 formed on flap 9 enable the severed or torn portions 9 of the flap adjacent the tear line 3 to fold upwardly relative to the remainder of the flap 9. Once the torn portions 9 have been folded upwardly so that the tab 4T is removed from the pocket P, the tab will project upwardly, see FIG.
  • the center segment 5 is manually pushed inwardly until it passes the plane of end wall B of the container whereupon said center segment will automatically snap into an inwardly extending closed position, as seen in FIG. 12.
  • the segment 5 will remain in its reclosed position until the tab 41 is once again pulled outwardly to form the pouring spout.
  • the segments 4, 5, and 6 assume the reclosed position, as seen in FIG. 12, the segments 4 and 6 are disposed in a fold-back contacting relation with the un derside of the torn portions 9' of the flap 9 and thus, the contents of the container are concealed from exposure to dirt, dust, or other foreign material.
  • the configuration of the container blank is simple and can be readily produced on conventional high speed scoring, slotting, and cutting equipment. Furthermore, a plurality of blank outlines can be arranged in nested relation on a sheet or web of blank material so that there is a minimum of material wastage. Where a large volume of blanks are being produced by automatic equipment, the amount of material wastage or scrap which results is an important cost factor.
  • an improved container and blank therefor have been provided wherein the container has a self-contained reclosable pull-out pouring spout.
  • the improved container is substantially leakproof when in its initially closed condition.
  • the improved container is of inexpensive, simple, yet sturdy, construction, and may be readily produced on conventional high speed equipment.
  • the pouring spout of the improved container is so constructed that it will automatically remain in either its extended or retracted positions.
  • the components of the improved pouring spout do not abut one another when the container is in its initially closed or reclosed positions and thus, manufacturing tolerances for the improved container need not be as carefully controlled as is the case with the prior structures.
  • a folding container for comminuted dry products having a self-contained, reclosable pouring spout, said container comprising foldably connected side and end walls, and closure flaps foldably connected to the upper edges of said walls and initially overlapping one another to form a substantially flat, exposed top surface; said closure flaps including an outer flap connected to a side wall and overlying and being adhesively secured only to an inner flap connected to an opposed side wall, a triangular end flap having one side thereof connected to an end wall, and triangular connecting flaps foldably connected to the remaining sides of said end flap and to the adjacent ends of said outer and inner flaps; one connecting flap being provided with a unitary projecting peripheral tab; the outer flap having a substantial portion of the end thereof projecting beyond the folding connection between said outer flap end and the connecting flap; said end and connecting flaps extending inwardly in fold-back relation when said container is initially closed and said peripheral tab being freely slidable into a snugly sandwiched relation between a closure flap connected to one side wall flap and the connecting flap fold
  • outer closure flap substantially spans the distance between the opposed side walls and is provided with a tear line extending endwise from the end of said outer flap which over- .lies the triangular end flap when said container is in an initially closed condition.
  • a blank of foldable sheet material for forming a container having pairs of side and end walls and closure flaps adapted when in one position of adjustment to form a pouring spout said blank comprising side wallfonning and end wall-forming panels arranged in alternate side-by-side relation, an outer closure flap foldably connected to and substantially coextensive with the upper edge of one side wall-forming panel, an inner closure flap foldably connected to and substantially coextensive with the upper edge of a second side wallforming panel, a triangular closure flap disposed intermediate said inner and outer closure flaps, said triangular closure flap having a side thereof foldably connected to the upper edge of one end wall-forming panel, triangular connecting flaps foldably connected to the remaining sides of said triangular closure flap, one connecting flap having a second side thereof foldably connected to an end of said inner flap; the other connecting flap having a second side thereof foldably connected to an end of said outer flap, said outer flap end extending beyond the connection between said outer flap and said other connecting flap,- the second side of
