INVENTOR. PRENTICE J. W000 structed and specially adapted for machine drop loading wherein the articles to be loaded into the carrier are automatically dropped from above the carrier into the respective articlereceiving cells thereof. Of course the cells in such a carrier must exceed in size in any transverse direction the corresponding transverse dimension of the articles to be packaged in order to insure effective loading.

Itis also knownthat basket style article carriers may be constructed with undersized cells whereby the resultant package is in effect a tight unitary article-enveloping structure which permits little if any relative movement between the packaged articles. Such tight packages are not feasible for use in conjunction with automatic droploading operations for obvious reasons and hence havenot met with substantial practical acceptance.

It has also been suggested that certain advantages may attend loading basket style carriers by introducing the articles from an open bottom or conversely by lowering a basket style carrier on to an assembled group of articles from above, the carrier bottom being open during such loading operations and then being closed following envelopment of the articles. Such known procedures have not been employed in conjunction with tight packages in so far as isknown.

' According to this invention a basket style carrier is completely formed except for its bottom structure and the transverse dimensional relationship between the cells of the carrier and the diameter of the articles to be packaged is such that the carrier cells when filled are tightly disposed about the articles, the tight finished carton being effective to prevent jostling of the articles and being made possible due to the fact that the packaged articles have upwardly tapered upper portions which facilitate guiding the carton into article enveloping relationship even though the cells are undersized. Of course a tight package can be constructed of mate rial such as paperboard which is substantially lighter in weight than would otherwise be required. In accordance with a feature of the invention, the partition elements are extensible so as to facilitate manual grasping of the carrier handle and carrying of the carrier by at? fording hand gripping space immediately adjacent the handle structure. I

For a better understanding of the invention reference may be had to the following detailed description taken in conjunction with the accompanying drawings in which FIG. I is a perspective view of a completely set up but unloaded carton formed according to the inven tion; FIG. 2 is a plan view of the blank from which the carton of FIG. 1 is formed; FIGS. 3, 4 and 5 depict sequential gluing and folding operations through which the blank of FIG. 2 is manipulated to form the completed and collapsed carrier as shown in FIG. 5, the bottom wall being left open as shown in FIG. 5; FIG. 6 is a side view showing a step in the loading of the carrier whereby the carrier of FIG. 5 is first set up and then lowered downwardly from above into enveloping relationship relative to a group of articles to be packaged; and in which FIG. 7 is a cross-sectional view taken along the line designated 7-7 in FIG. 6.

In the drawings the numeral 1 designates a side wall of the carrier to the bottom edge 2 of which a bottom panel 3 is foldably joined. A plurality of locking tabs 4 are formed along one edge of bottom panel 3. End wall panel 5 is foldably joined to side wall 1 along fold line 6 while end wall 7 is foldably joined to side wall I along fold line 8. i V

For the purpose of rendering the carton corners readily conformable with the packaged articles, a pair of weakened lines 9 and 10 are formed in side wall 1 near the end edges 6 and 8 thereof and weakened

lines

11 and 12 are formed in

end wall panels

5 and 7 respectively. In like fashion weakened

lines

13 and 14 are formed in

end wall panels

5 and 7 near the opposite edges thereof.

For interconnecting the tray portion of the carrier with its handle structure, a pair of

riser panels

15 and 16 are foldably joined along fold lines 17 and 18 to the inner edges of

end wall panels

5 and 7 respectively.

The handle structure of the carton is of a composite construction and includes a handle panel 19 foldably joined along fold line 18 to riser panel 16 together with a handle panel 20 foldably joined to handle panel 19 along a medial fold line 21.

Hand gripping apertures

22 and 23 are formed in

handle panels

19 and 20 respectively.

The handle structure of the carton is reinforced by reinforcing

panels

24 and 25 which are foldably joined to handle

panels

19 and 20 along fold lines 26 and 27 respectively.

Handle panels

24 and 25 are interconnected with each other along medial fold line 28 and hand gripping apertures 29 and 30 are formed in

ban dle panels

24 and 25 respectively.

For the purpose of subdividing the carrier on one side of the handle into cells, one or morepartition elements are provided. Such elements are designated in the drawings by the

numerals

31 and 32. Partition element 31 is foldably joined to side wall 1 along fold line 33 and to handle panel 19 along fold line 34. Similarly partition element 32 'is foldably joined to side wall 1 along fold line 35 and to handle panel 19 along fold line 36.

The opposite side of the carrier is of generally similar construction and comprises a riser panel 37 which is foldably joined to riser panel 15 along medial fold line 38 together with riser panel 39 which is foldably joined to handle panel 20 along fold line 40. End wall 41 is foldably joined toriser panel 37 along fold line 42 while end wall 43 is foldably joined to riser panel 39 along fold line 44. Side wall 45 is foldably joined along fold line 46 to end wall panel 41 and along fold line 47 to end wallpanel 43.

For the purpose of rendering the corners of the carton yieldable, weakened

fold lines

48 and 49 are 3 formed in side wall 45 and similar weakened lines 50 and 51 are formed in end wall panel 41 while weakened lines 52 and 53 are formed in end wall panel 43.

The bottom panel 54 is. foldably joined along fold line 55 to the bottom edge of side wall 45. A plurality of retaining tabs 57 are formed in bottom wall panel 54 and define openings for receiving the locking tabs 4 as is obvious.

For dividing one side of the carton into a plurality of cells. a partition element 58 is foldably joined to side wall 45 along fold line 59 and to handle panel 20 along fold line 60. Similarly a partition element 61 is foldably joined to side wall 45 along fold line 62 and to handle panel 20 along fold line 63.

In order to form the carrier, an application of glue is first made to the blank of FIG. 2 as indicated by stippling in that figure. Thereafter reinforcing

panels

24 and 25 are elevated and folded toward the right along fold lines 26 and 27 to occupy the positions depicted in FIG. 3.

An application of glue is then made to the blank as shown in FIG. 3 and as indicated by stippling in that figure. Thereafter

end wall panels

5 and 41 and the structure associated therewith are elevated and folded toward the right along the fold lines 6 and 46 to occupy the positions depicted in FIG. 4. This action causes the riser panels and 37 to become adhered to the inner surfaces of

handle panels

19 and 20 and of reinforcing

panels

24 and 25. Simultaneously

riser panels

16 and 39 are elevated and folded toward the left along fold lines 18 and 40 to occupy positions indicated in FIG.

4. This action of course causes the

riser panels

16 and 39 to adhere at the upper ends thereof to the inner surfaces of

handle panels

19 and 20. The carrier then appears as depicted in FIG. 4.

. In order to complete the folding and gluing operations, an application of glue is made to the carrier as indicated by stippling in FIG. 4 after which side wall 1 and portions associated therewith which are disposed above the fold lines 2l, 28. and 38' are elevated and folded forwardly to occupy the positions depicted in FIG. 5. FIG. 5 showsfthe carrier collapsed following completion of manufacture by acarton manufacturer after which it is shipped to a'user such as a bottler.

, The particular handle structure is shown as an example only. Of course the invention is not limited to any particular handle arrangement and handle structures other than that shown may be used in practicing the invention.

In order to apply the carrier to a group-of bottles, the carrier is first partially setup by drawing the side walls apart and by. applying a force to the right hand edge of the carrier as shown in FIG. 5 while holding the side walls 1 and against sidewise displacement. This action causes the walls to occupy the positions depicted in FIG. 6 where the carrier is shown immediately above a group of bottles B whose upper portions or necks N are upwardly tapered. In FIG. 6 the carton is shown in the process of being lowered downwardly into enveloping relationship with respect to a group of bottles 8". After the side walls 1 and 45 reach their lowermost positions, bottom wall panel 54 is folded inwardly underneath the bottles B" followedby inward folding of bottom wall panel 3 to cause the locking tabs 4 to become aligned with retaining tabs 57. Thereafter the locking tabs 4 are driven through the openings defined by the retaining tabs 57 and the carrier is then' complete. Ordinarily the bottles rest upon a conventional sword or the like and move continuously throughout the packaging operation during the lowering and locking operations.

While the carrier of this invention may be loaded by hand or by any suitable apparatus, the machine of US. Pat. No. 3,747,294 granted July 24, 1973 is well adapted for use in loading the carrier of this invention.

It will be understood thatthe invention is not limited to cartons having locking tabs and that other means such'as glue may be used to adjoin the

panels

3 and 54.

As has been explained and as is apparent from FIG. 7, the transverse dimensions or nominal diameters such as D of the bottles plus the thickness T of the partition elements such as'58 and 61 when added together constitute an appreciably greater overall longitudinal distance than is the length of the handle structure S or the length of either side wall 1 or 45. Thus the cells are undersizeand conformance of the corners of the cellsis necessary. Furthermore, the loading of the carrier is feasible with the undersized cells due to the guiding action of the upwardly tapered neck portions N" of the bottles B. It is also apparent that the weakened lines such as 10, 12 and 14 facilitate conformance of the corners of the carrier with the adjacent bottles. Since the articles are gripped by the tension force of the side and end walls and of the handle structure and partition elements, very little load is applied to the bottom wall directly. Furthermore from FIG. 7 it is apparent that the partition straps 58, 61, 31 and 32 bow outwardly to accommodate the oversized middle bottle on each side of the handle structure S. It is also apparent that the resulting package is well adapted to be formed on automatic high speed machinery and that when completely finished, the tightness of the various carton panels insures that the packaged bottles B are held immovable with respect to each other and hence are protected against breakage'due to jostling. In addition, the tightness of the wrapper is possible due to the novel method by which the package is formed and can be achieved with minimum thickness of material such as paperboard.

The term diameter is sometimes used herein to denote the the dimension D of the articles B and is an apt term where the articles are circular in crosssection. The term is also used in denote articles of different cross sectionalconfiguration such as hexagonal, octagonal and the like. If the number of faces is increased sufficiently, the article approaches a circular cross sectional configuration.

To facilitate carrying and to provide hand room adjacent handle structure S, the partition elements such as 31', 32, 58 and 61 are extensible. Toward this end, curved slits 64 and 65 are formed in side wall 1 and in handle panel 19 near the fold lines 33 and 34 respectively as is best shown in FIG. 1. Similar slits are formed near the ends of

partition elements

32, 58 and 61 and serve to accommodate relative transverse movement of the side-walls'and handle structure.

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:
