Description
~84008 The invention relates to a carton for containers having the shape of a truncated cone. More specifically, the invention relates to such a carton which permits ventilation of the containers and wherein the container covers are dis-played so that any markings on their top surface can be seen.
The invention also relates to blanks from which the cartons are formed.
Cartons for shipping, and/or displaying containers of the above-described type, which containers may be filled with yogurt, cottage cheese, etc., usually are of the large, box-type variety in which the containers are stacked in layers.
The boxes are usually fully closed so that ventilation of the containers is not possible. In addition, the flavours or con-tents must either be marked on the outside surface of the carton, or the carton must be opened to see the markings on the containers.
It is therefore an object of the invention to pro-vide a carton which overcomes the above disadvantages.
It is a more specific object of the invention to provide such a carton which permits ventilation of the con-tainers it holds.
It is a still further object of the invention to provide such a carton which is reiatively simple and inexpen-sive to produce, In accordance w~th the invention, a carton for containers co~prises: a top surface having a plurality of openings for receiving said containers, a solid bottom surface disposed below said top surface in spaced, parallel relation-ship thereto, side walls, spacedly connecting said top and bottom surfaces at respective side edges thereof, end flaps extending from said bottom surface to said top surface at -- 1 -- ,~t,~
400~
respective end edges thereof, said side walls and said end flaps comprising a plurality of openings whereby to permit ventilation of containers loaded in said carton, and means on the bottom surface of said carton for preventing movement of a top carton relative to a bottom carton when a plurality of said cartons are stacked one on top of the other.
The carton may further include tabs extending up-wardly from the top edges of each of said end flaps, and slots at both ends of said top surface, said tabs extending through respective ones of said slots and above said top surface.
The means for preventing movement may comprise a set of side legs and a set of end legs, said side legs extend-ing downwardly from said side walls below said bottom surface, said end legs extending downwardly from said end flaps below said bottom surface, whereby, when a plurality of said cartons are stacked one on top of the other, the end legs of a top carton will abut respective ones of said tabs of a bottom carton and the side legs of a top carton will abut adjacent ones of said containers of a bottom carton to thereby prevent movement of the top carton relative to the bottom carton.
Alternatively, the means for preventing movement may comprise bottom slots at both ends of said bottom surface, whereby, when a plurality of cartons are stacked one on top of the other, the tabs of a bottom carton will extend through respective bottom slots of a top carton to thereby prevent movement of the top carton relative to the bottom carton.
In accordance with an embodiment of the invention, a blank for forming a carton for containers comprises: a bottom panel for forming a bottom surface of said carton, said bottom panel having a first end and a second end and a first side and a second side, a first flap, for fonning a 1')8400~
first end flap of said carton, foldingly joined to said first end of said bottom panel, at one side thereof, and a first tab extending from the other side of said first flap, a second flap, for forming a second end flap of said carton, foldingly joined to said second end of said bottom panel, at one side thereof, and a second tab extending from the other side of said second flap, a first side panel, for forming a first side wall of said carton, foldingly joined to the first side of said bottom panel, at one side thereof, a top panel, for forming a top surface of said carton, foldingly joined to the other side of said first side panel, at one side thereof; a second side panel, for forming a second side wall of said carton, foldingly joined to the other side of said top panel, at one side thereof, a plurality of openings in said top panel for receiving said containers in the formed carton, a plurality of openings in said side panels and end flaps for forming ventilation openings in the formed carton, and slots at either end of said top panel for receiving a respective one of said first and second tabs in the formed carton.
The blank may further comprise a third tab foldingly joined to the other side of said second panel.
The blank may ~till further comprise a first set of side tabs, for forming side legs in the formed carton, extend-ing from the one side of said first panel and cut out from said bottom panel, a second set of side tabs, for forming side legs in the formed carton,extending from the other side of said second panel and cut out from said third tab, a first set of end tabs, for forming end legs, extending from the one side of said first flap and cut out from said bottom panel, and a second set of end tabs, for forming end legs, extending from the one side of said second flap and cut out lt)84008 from said bottom panel.
Alternatively, the blank may still further comprise a pair of bottom slots, each said bottom slot being located at a respective end of said bottom panel, The invention will be better understood by an examination of the following description, together with the accompanying drawings, in which:
Figure 1 is a perspective view of one embodiment of the invention;
Figure 2 is a side view of the embodiment of Figure 1, Figure 3 i~ an end view of the embodiment of Figure l;
Figure 4 illustrates a blank for forming a carton as shown in Figure 1, Figure 5 is a perspective view of a second embodi-ment of the invention;
Figure 6 is a side view of the embodiment shown in Figure 5, Figure 7 is an end view of the embodiment shown in Figure 5; and Figure 8 illustrates a blank for forming a carton as shown in Figure 5, Referring now to Figures 1 to 3, the carton, shown generally at 1, includes a top surface 3 and a bottom surface 5 which, as seen in Figures 1, 4, 5 and 8, is solid. Included in the top surface are a plurality of openings 7 for receiving containers. Side openings 9, in side walls 10, permit venti-lation of the containers held in the carton, as do also end openings 11 in end flaps 13. Tabs 15 extend from the flaps 13 as described below.
10~400~
The carton also includes a plurality of end legs 17 and side legs 19 which extend below the bottom surface from the end flaps 13 and side walls 10 respectively.
Figure 2 illustrates how the cartons in accordance with the invention would be stacked, when they are loaded with containers, for shipping or storage. As can be seen, the con-tainers 21 are truncated cone shaped with the base of the trun-cated cone constituting the top end of the container. When the container is unloaded, it has virtually no structural strength and can be easily folded into a flattened position even after it has been formed. However, when the carton is loaded, the weight and rigidity of the containers, together with the faci-lity of the carton to retain the containers in fixed relation-ship, combine to form a firm and rigid package.
In the stacked position, the legs 17 and 19 help prevent a top carton from slipping off the carton beneath it.
Thus, legs 17 of the top carton abut with tabs 15 of a bottom carton to prevent back and forth motion. This is shown in Figure 2.
AS seen in Figures 2 and 3, the top surface of each container is at a higher level than the top surface of the carton. The bottom surface of the upper carton will thus rest on the top surfaces of the containers in the bottom carton.
In addition, the legs 19 will abut the extending portions of the container to prevent side to side motion of the top carton.
Because the top covers of the cartons are not ~ covered up, it is possible to read the markings on the covers.
'~` As above-mentioned, the openings ~ and ~r permit air to flow through the carton so that the containers are ventilated in the package. In addition, these openings can 1')8400~
be used as handles when lifting the loaded cartons.
Referring now to Figure 4, the carton is formed from a blank having a top panel 30, for forming the top surface, and a bottom panel 50, for forming the bottom surface. The side walls are formed from the side panels 100, and the end flaps are formed from the flaps 130. Tabs 150 extend from the top sides of the flaps 130. Side legs 19 are formed from the tabs 190, which extend from the panels 100, and end legs 17 are formed from the tabs 170, which extend from the inner edge of the flaps 130 and are cut out of panel 50.
Extending from the free side of that panel 100 which extends from the free edge of panel 3, is a tab member 25 whose function will be discussed below. Legs 19, extending from the just-mentioned panel 100, are cut out of the tab member 25, while legs 19, extending from the other panel 100, are cut out of the panel 50.
Extending between tab 25 and adjacent panel 100 are Cllt lines 31, defining the tahs 190, and fold lines 29, Ex-tending between the just-mentioned panel 100 and panel 30 is fold line 33, while cut and fold line 35 extends between panel 30 and the other panel 100. Cut lines 39 define the other set of tabs 190, and these cut lines, and the fold lines 37 extend between the other panel 100 and the panel 50. Cut and fold lines 41,43 and 47,45 extend between respecti~e ones of the flaps 150 and the panel 50 and define the end legs 17. Glue spots 27 are disposed at the free edge of the panel 50.
To form a carton from the above-described blank, the panel 100, extending from the free side of the panel 30, is folded downwardly and at right angles to the panel 30. The tab 25 is then folded inwardly and at right angles to its adjacent panel 100 so that it underlies and is parallel to ~')8400~
the panel 30.
Flaps 130 are then folded downwardly and at right angles to the panel 50, and panels 50 and 100, adjacent to panel 50, are folded downwardly and at right angles to panel 30. Panel 50 is then folded at right angles to its adjacent panel 100 so that it underlies and is parallel to the panel 30. The glued surface of the panel 50 is disposed on the inner surface of the tab member 25 so that tab 25 is adhered to panel 50. Tabs 150 extend through the slots 23 which are disposed on either side of the panel 30.
Turning now to Figures 5 to 8, wherein like reference numerals denote the same parts as in Figures 1 to 4, it can be ~een that the second embodiment, illustrated in Figures 5 to 8, is the same as the first embodiment except that the Figures 5 to 8 embodiment does not have any legs 17 or 19, or tabs 170 or 190 forming these legs. Instead, in the Figures 5 to 8 embodiment, there are slots 170 disposed at the ends of panel 50. As seen in Figures 6 and 7, the tabs 15 will extend through the slot~ 170 when the cartons are stacked one on top of the other. Thus, motion of the top carton on the bottom carton is prevented by the stopping effect of the tabs 15 extending through the slots 170.
In the blank, as shown in Figure 8, panel 30 is joined to one panel 100 by cut and fold line 151, and to the other panel 100 by cut and fold line 153. The one panel 100 is joined to tab 25 by cut and fold line 155, and the other panel 100 is joined to panel 30 by cut and fold line 157.
Cut ~ines 159 and 161 join respective flaps 130 to respective ends of the panel 50.
The carton of Figure 5 is formed from the blank of Figure 8 in the same way the carton of Figure 1 is formed from 1.')~4QO~
the blank of Figure 4.
As can be seen, both embodiments of the invention provide cartons which permit ventilation of the containers in the cartons, and which are relatively simple and inex-pensive to produce.
The inventive carton can be used for shipping, or storing the containers, or for displaying the containers at the point of sale.
Although several embodiments were described in the foregoing, this was for the purpose of illustrating, but not limiting, the invention. Various modifications, which will come readily to the mind of one skilled in the art, are within the scope of the invention as defined in the appended claims.
The invention also relates to blanks from which the cartons are formed.
Cartons for shipping, and/or displaying containers of the above-described type, which containers may be filled with yogurt, cottage cheese, etc., usually are of the large, box-type variety in which the containers are stacked in layers.
The boxes are usually fully closed so that ventilation of the containers is not possible. In addition, the flavours or con-tents must either be marked on the outside surface of the carton, or the carton must be opened to see the markings on the containers.

respective end edges thereof, said side walls and said end flaps comprising a plurality of openings whereby to permit ventilation of containers loaded in said carton, and means on the bottom surface of said carton for preventing movement of a top carton relative to a bottom carton when a plurality of said cartons are stacked one on top of the other.
The carton may further include tabs extending up-wardly from the top edges of each of said end flaps, and slots at both ends of said top surface, said tabs extending through respective ones of said slots and above said top surface.
The means for preventing movement may comprise a set of side legs and a set of end legs, said side legs extend-ing downwardly from said side walls below said bottom surface, said end legs extending downwardly from said end flaps below said bottom surface, whereby, when a plurality of said cartons are stacked one on top of the other, the end legs of a top carton will abut respective ones of said tabs of a bottom carton and the side legs of a top carton will abut adjacent ones of said containers of a bottom carton to thereby prevent movement of the top carton relative to the bottom carton.

The blank may further comprise a third tab foldingly joined to the other side of said second panel.
The blank may ~till further comprise a first set of side tabs, for forming side legs in the formed carton, extend-ing from the one side of said first panel and cut out from said bottom panel, a second set of side tabs, for forming side legs in the formed carton,extending from the other side of said second panel and cut out from said third tab, a first set of end tabs, for forming end legs, extending from the one side of said first flap and cut out from said bottom panel, and a second set of end tabs, for forming end legs, extending from the one side of said second flap and cut out lt)84008 from said bottom panel.
Alternatively, the blank may still further comprise a pair of bottom slots, each said bottom slot being located at a respective end of said bottom panel, The invention will be better understood by an examination of the following description, together with the accompanying drawings, in which:
Figure 1 is a perspective view of one embodiment of the invention;
Figure 2 is a side view of the embodiment of Figure 1, Figure 3 i~ an end view of the embodiment of Figure l;
Figure 4 illustrates a blank for forming a carton as shown in Figure 1, Figure 5 is a perspective view of a second embodi-ment of the invention;
Figure 6 is a side view of the embodiment shown in Figure 5, Figure 7 is an end view of the embodiment shown in Figure 5; and Figure 8 illustrates a blank for forming a carton as shown in Figure 5, Referring now to Figures 1 to 3, the carton, shown generally at 1, includes a top surface 3 and a bottom surface 5 which, as seen in Figures 1, 4, 5 and 8, is solid. Included in the top surface are a plurality of openings 7 for receiving containers. Side openings 9, in side walls 10, permit venti-lation of the containers held in the carton, as do also end openings 11 in end flaps 13. Tabs 15 extend from the flaps 13 as described below.
10~400~
The carton also includes a plurality of end legs 17 and side legs 19 which extend below the bottom surface from the end flaps 13 and side walls 10 respectively.
Figure 2 illustrates how the cartons in accordance with the invention would be stacked, when they are loaded with containers, for shipping or storage. As can be seen, the con-tainers 21 are truncated cone shaped with the base of the trun-cated cone constituting the top end of the container. When the container is unloaded, it has virtually no structural strength and can be easily folded into a flattened position even after it has been formed. However, when the carton is loaded, the weight and rigidity of the containers, together with the faci-lity of the carton to retain the containers in fixed relation-ship, combine to form a firm and rigid package.
In the stacked position, the legs 17 and 19 help prevent a top carton from slipping off the carton beneath it.
Thus, legs 17 of the top carton abut with tabs 15 of a bottom carton to prevent back and forth motion. This is shown in Figure 2.
AS seen in Figures 2 and 3, the top surface of each container is at a higher level than the top surface of the carton. The bottom surface of the upper carton will thus rest on the top surfaces of the containers in the bottom carton.
In addition, the legs 19 will abut the extending portions of the container to prevent side to side motion of the top carton.
Because the top covers of the cartons are not ~ covered up, it is possible to read the markings on the covers.
'~` As above-mentioned, the openings ~ and ~r permit air to flow through the carton so that the containers are ventilated in the package. In addition, these openings can 1')8400~
be used as handles when lifting the loaded cartons.
Referring now to Figure 4, the carton is formed from a blank having a top panel 30, for forming the top surface, and a bottom panel 50, for forming the bottom surface. The side walls are formed from the side panels 100, and the end flaps are formed from the flaps 130. Tabs 150 extend from the top sides of the flaps 130. Side legs 19 are formed from the tabs 190, which extend from the panels 100, and end legs 17 are formed from the tabs 170, which extend from the inner edge of the flaps 130 and are cut out of panel 50.
Extending from the free side of that panel 100 which extends from the free edge of panel 3, is a tab member 25 whose function will be discussed below. Legs 19, extending from the just-mentioned panel 100, are cut out of the tab member 25, while legs 19, extending from the other panel 100, are cut out of the panel 50.
Extending between tab 25 and adjacent panel 100 are Cllt lines 31, defining the tahs 190, and fold lines 29, Ex-tending between the just-mentioned panel 100 and panel 30 is fold line 33, while cut and fold line 35 extends between panel 30 and the other panel 100. Cut lines 39 define the other set of tabs 190, and these cut lines, and the fold lines 37 extend between the other panel 100 and the panel 50. Cut and fold lines 41,43 and 47,45 extend between respecti~e ones of the flaps 150 and the panel 50 and define the end legs 17. Glue spots 27 are disposed at the free edge of the panel 50.
To form a carton from the above-described blank, the panel 100, extending from the free side of the panel 30, is folded downwardly and at right angles to the panel 30. The tab 25 is then folded inwardly and at right angles to its adjacent panel 100 so that it underlies and is parallel to ~')8400~
the panel 30.
Flaps 130 are then folded downwardly and at right angles to the panel 50, and panels 50 and 100, adjacent to panel 50, are folded downwardly and at right angles to panel 30. Panel 50 is then folded at right angles to its adjacent panel 100 so that it underlies and is parallel to the panel 30. The glued surface of the panel 50 is disposed on the inner surface of the tab member 25 so that tab 25 is adhered to panel 50. Tabs 150 extend through the slots 23 which are disposed on either side of the panel 30.
Turning now to Figures 5 to 8, wherein like reference numerals denote the same parts as in Figures 1 to 4, it can be ~een that the second embodiment, illustrated in Figures 5 to 8, is the same as the first embodiment except that the Figures 5 to 8 embodiment does not have any legs 17 or 19, or tabs 170 or 190 forming these legs. Instead, in the Figures 5 to 8 embodiment, there are slots 170 disposed at the ends of panel 50. As seen in Figures 6 and 7, the tabs 15 will extend through the slot~ 170 when the cartons are stacked one on top of the other. Thus, motion of the top carton on the bottom carton is prevented by the stopping effect of the tabs 15 extending through the slots 170.
In the blank, as shown in Figure 8, panel 30 is joined to one panel 100 by cut and fold line 151, and to the other panel 100 by cut and fold line 153. The one panel 100 is joined to tab 25 by cut and fold line 155, and the other panel 100 is joined to panel 30 by cut and fold line 157.
Cut ~ines 159 and 161 join respective flaps 130 to respective ends of the panel 50.
The carton of Figure 5 is formed from the blank of Figure 8 in the same way the carton of Figure 1 is formed from 1.')~4QO~
the blank of Figure 4.
As can be seen, both embodiments of the invention provide cartons which permit ventilation of the containers in the cartons, and which are relatively simple and inex-pensive to produce.
The inventive carton can be used for shipping, or storing the containers, or for displaying the containers at the point of sale.
Although several embodiments were described in the foregoing, this was for the purpose of illustrating, but not limiting, the invention. Various modifications, which will come readily to the mind of one skilled in the art, are within the scope of the invention as defined in the appended claims.
