Heavy duty article carrier

Abstract

The top wall of an article carrier is provided with a pair of hand gripping apertures and a number of score lines are arranged to extend from adjacent an end of a hand gripping aperture outwardly in a diverging path toward the corners of the top wall. By this means the top wall of the carrier is rendered especially strong by efficiently distributing the weight of the carrier and its contents so that the caliber of board used may be substantially reduced and economies thereby effected.

Description

TECHNICAL FIELD

This invention relates generally to hand carried article carriers and is particularly concerned with the construction of hand gripping apertures and related scores formed in the top carrier wall.

BACKGROUND ART

U.S. Pat. No. 3,904,036 issued Sep. 9, 1975 owned by the assignee of this invention discloses a fully enclosed article container specially adapted for use with bottles having sloping shoulders.

SUMMARY OF THE INVENTION

A carrier having a bottom wall of rectilinear configuration includes opposed side walls and opposed end walls interconnected at their end edges with each other and which are foldably joined to the side and end edges of the bottom wall. According to this invention in one form, the top wall of the carrier is specially constructed so as to distribute the load in such manner that the carrier may be used effectively with board of a smaller caliber than is used at the present time. One feature of this invention concerns the formation of scores in the top wall which emanate from a point close to a hand gripping aperture and which diverge toward each corner of the top wall but are separated therefrom.

According to a modification of this invention, the divergent scores in top wall are arranged so as to terminate at bevelled corners of the top panel.

BEST MODE OF CARRYING OUT THE INVENTION

With reference to FIG. 1, the numeral 1 designates the bottom wall of the carrier. Bottom end flap 2 is foldable joined to an end edge of bottom wall 1 along fold line 3. Bottom end flap 4 is foldably joined to bottom wall 1 along fold line 5.

Side wall 6 is foldably joined to a side edge of bottom wall 1 along fold line 7. A side end flap 8 is foldably joined to side wall 6 along fold line 9. Side end flap 10 is foldably joined to side wall 6 along fold line 11.

At the other end of the blank, side wall 12 is foldably joined to bottom wall 1 along fold line 13. Side end flap 14 is foldably joined to side wall 12 along fold line 15. Side wall flap 16 is foldably joined to side wall 12 along fold line 17.

The top wall of the carrier according to this invention is formed of parts located at opposite ends of the blank shown in FIG. 1. Top wall pane 18 is foldably joined to side wall 6 along a fold line 19. Top end flap 20 is foldably joined to an end edge of top wall panel 18 along fold line 21. Portions of a tear strip formed in part in top wall panel 18 and in part in top end flap 20 is designated by the numeral 22. At the other end of top wall panel 18 top end flap 23 is foldably joined to top wall panel 18 along fold line 24. A tear strip 25 is formed in part in top end flap 23 and in part in top wall panel 18.

A hand hole aperture 27 is formed in top wall panel 18 and is of well known construction.

According to this invention, a plurality of score lines such as 28, 29 and 30 emanate from adjacent one end of hand gripping aperture 27 and diverge outwardly toward weakened severance line 31.

At the other end of the hand gripping aperture 27, a plurality of score lines 32, 33 and 34 are formed and emanate from a position adjacent one end of hand gripping aperture 27 and diverge as they approach the weakened line 35 at the outer extremity of the score lines 32, 33 and 34.

The top panel 18a at the opposite end of the blank from top panel 18 is identical to panel 18 in all respects except that reinforcing strip 26 is foldably joined to panel 18a along fold line 26c. This reinforcing strip has an end portion 26a at one end and a similar end portion 26b at the other end. The numerals used in connection with top panel 18a are duplicates of the numerals used in connection with top panel 18 except for the addition of the suffix a. The top end flaps associated with top wall panel 18a are designated by the numerals 20a and 23a. Tear strip 22a and tear strip 25a designate the tear strips similar to those at the opposite end of the blank.

FIG. 2 is simply a representation of the position of reinforcing strip 26 and its associated end portion 26a and 26b. These elements 26, 26a and 26b are secured by adhesive to the top panel 18 and to the top end flaps 20 and 23.

The blank of FIG. 2 is manipulated into the condition represented by FIG. 3 by folding top panel 18 and top end flaps 20 and 23 upwardly and toward the right along fold line 6a. Thereafter the side wall panel 12 the top panel 18a together with the end flaps 20a and 23a are folded upwardly and toward the left along fold line 13 to position these parts as shown in FIG. 4. This operation causes the hand gripping apertures 27 and 27a to become associated with and spaced from each other as is well known. The carrier then is shown in FIG. 4 in collapsed condition.

FIG. 5 shows the carrier from one end when fully set up but which is either not loaded or which is shown without load distribution due to lifting via apertures 27 and 27a.

FIG. 6 is similar to FIG. 5 but shows the carrier loaded and lifted by grasping apertures 27 and 27a. This view shows the scores 32, 33, 34 and 32a, 33a and 34a formed in top panels 18 and 18a.

In FIG. 7, the near end of the carton shows the weakened severance lines 35 and 35a which facilitate upward folding of the score lines 32, 33, 34 and 32a, 33a and 34a.

FIGS. 8-12 inclusive disclose a modification of the invention wherein the score lines formed in the top wall terminate at bevelled corners of the top wall which are adjacent to bevelled corner strips.

With respect to FIG. 8, the bottom wall is designated by the numeral 40 and bottom end flap 41 is foldably joined to bottom wall 40 along fold line 42. Bottom end flap 43 is foldably joined to bottom wall 46 along fold line 44. Side wall 45 is foldably joined to bottom wall 40 along fold line 46. Side flaps 47 and 48 are foldably joined to the bevelled strip 49 and 50 respectively.

Side wall 51 is foldably joined to bottom wall 40 along fold line 52. End flaps 53 and 54 are foldably joined to bevelled strips 55 and 56 as is obvious.

The top wall of the carrier is formed of two parts designated 56 and 56a. Top end flaps 57 are foldably joined to top wall panel 56 along fold line 58. Top end flap 59 is foldably joined to top wall panel 56 along fold line 60. A hand gripping aperture 61 is formed in top wall panel 56 and a reinforcing strip 62 is foldably joined to top wall panel 56 along fold line 62a. The reinforcing strip 62 includes end portions 64 and 65. End flap at the opposite end of the blank are designated by the same numerals with the suffix a added as are used in connection with top wall panel 56.

The end flaps of the carton are interconnected by foldable web structures 70-77. This construction is similar to that shown in U.S. Pat. No. 4,216,861.

FIG. 9 shows the blank of FIG. 1 manipulated into finished condition and shown in collapsed form.

FIG. 10 shows the carrier of FIG. 8 set up but not lifted under load.

In accordance with the modification of the invention, vertically disposed bevelled strips are formed at each corner of the carton.

As is obvious from FIGS. 11 and 12 the score lines such as 32-34 and 32a-34a are bowed upwardly especially as is apparent in FIG. 11 and portions of the weight of the load distributed by these score lines. The top ends of bevelled panels 50 and 56a are designated at 80 and 81 which coincide with the ends of the score lines such as 32-34 and 28-30 provided in the top panels 56 and 56a.
