Abstract
ABSTRACT
A paperboard carton for containing and pouring liquid has a pour spout fitment adhesively secured to its upper surface and at least partially over a reinfor-cing patch on said upper surface to spread the upward force exerted by opening the fitment over an area of the carton surface larger than the bottom surface of the fitment so as to prevent the fitment from being torn away from the carton surface. In addition to the force distribution, the tensile strength of the added patch material is much greater than the strength of the carton coating, thus this new patch material becomes the primary seal.

Description
~313~2 PLASTIC POUR SPOUT BONDING
~ackground of the Invention This invention relate~ to a paperboard carton blank and carton for packaging and dispen~ing potable liquid s~ch as milk through a pour spout.
A preferred embodiment comprises a carton which is made from a flat blank from which it is poured, the outside surface of which is coated with a plastic ~uch as polyethylene to give it strength and make it liquid impervious.
One form of it has a separate pour spout ~tructure, preferably made of plastic, which include~ a base part with an opening in it, secured to the carton surface and a cover or closure part releasably secured to the base part and over the opening to form a seal.
The cover may have a pull tab by which it may be grasped by the user to pull it away from the ba~e part to expose the pour opening.
It has been found that many times, in lifting the cover, the user also pull~ the ba~e part at least par-tially away from the carton surface thus di~rupting th~
proper function of the pour spout.
It is accordingly the general object sf this inven-tion to prevent this tearing away of the pour ~pout fitment by ~treng~hening the bond between the fitment and the surface of the carton.
13136~2 Sum~ o~ the Inventio_ A~ will appear in the more det~iled description and drawing~, the carton, when erected from the blank, may, among others, be either of the so-called gable top or flat top type. The pour spout fitment is located on one of its upper surfaces, preferably over a pour opening in the carton blank surface. I~ has a base part normally with a pour opening in it to register with the pour opening in the carton surf~ce, and a removable ~losure part over the base part.
Before applying the spout fitment to the carton surface, a reinforcing patch is applied to the surface.
This patch is of such shape and Rize that when the fitment is applied over it, the patch extends beyond the outer edges of the ~itment.
The fitment is then adhesively applied either part-ly directly to the plastic coated carton ~urface and partly to the reinforcing patch, or else entirely over the patch.
Thus, when the user applies force to remove the cover part from the ba~e part, the force i8 spread through the reinforcing patch and over a ~ubstantially greater area than that covered by the base part, in addition the strength of the patch is now the controlling factor, thereby strengthening the bond between the fitment and the carton and preventing the fitment from being partially or entirely torn away from the carton surface.

Detailed Description Two of several types of carton included in this invention to contain and pour liquid are indicated at 8 and 10 in Fiyures 1-7 inclusive. The carton type 8 is a gable top carton and the type 10 is a flat top type.
The pour spout arrang~ent of the invention may take severaL forms any of which may be combined with the carton types 8 and 10 shown and others.
One such pour spout form is indicated at 12 in Figures 1 and 3, 6 and 7 and 8-11 inclusive. An alter-nate form of pour spout is indicated at 14 in Figures 4 and 5.
While the pour spout fitments of Figures 1 and 3, 6 and 7 and 8-11 are essentially the same, the attachment of the fitments 12 of Figures 8-11 to the carton are different from that of the others shown as further explained.
The invention covers the pour spout arrangements in cartons exemplified by those 8 and 10 of Figures 1-7 inclusive and in carton blanks part~ of which are indi-cated at 16 in Figures 8-11 inclu~ive for making such cartons.
Referring particularly to Figure 2f a pour hole 18 may be formed in a selected area of part of a carton blank which becomes the center of an upper surface part 20 of a carton 8 although this may not be e~sential.
,_ A reinforcing patch 22 is adhesively secured or sealed using the various methods available in the industry to secure polymers together to thi3 upper surface carton part 20 in the selected area and squarely ... .
13~3~42 over the pour hole 18. The patch 22 may or may not al~o ha~e a corresponding pour hole according to the characteristics desired in a particular structure. If it does have a pour hole, the latter will be located in register over the hole 18 in the carton 8. If it does not, the intent will be to have the patch function as a seal until pierced by the end user of the carton in order ~o be able to pour the contained liquid. In this latter case the characteristic of the material to be used for the patch will be selected so ~hat it may be readily pierced by the end user and yet strong enough to serve its primary purpose of preventing the pour spout fitment 12 or 14 to be attached to the carton from being accidentally torn away from the carton surface while beinq opened as further described.
The variation in degree of de~irable strength of the patch material results from the type of material selected for its use and its thickness and will depend upon end usage need~. For instance, it will most often be used on polyethylene coated paperboard stock for making liquid cartons.
Examples of compatible materials are 2 to 6 mil low density polyethylene, a la~ination of 1 mil low density polyethylene,polyester and 1 mil low density polyethy-lene, 2 mils high density polyethylene, and à laminationof 1 mil high density polyethylene, polyester and 1 mil high density polyethylene.
These patch materials may be applied to the poly-ethylene coated carton surface with pressure sensitivs adhesive, by direct heat, radiant heat, hot air or impulse heati~g under pressure ~ith a short surge of heat.
The pour spout fit~ent 12 o~ Figures 1 and 3, 6 and 7 and 8-11 bes~ seen in Figures 8-11 may be made of 30 mil high density polyethylene.
1313~2 Portion 26 may be adhesively secured by any of the methods mentioned above to either o~ the upper surface parts ~0 or 20a of the cartons 8 and 10 either partially or entirely over the reinforcing patch 22.
It also has a closure part 28 hinqed at 30 to the base part 24 and removably secured as by contact q1uing to the base part. When so secured, it provides a leak proof closure over the pour hole 18 and when removed from the base part by pulling it upwardly so as to pivot it around the hinge 3~, it opens the pour hole to allow the contained liquid to be poured out or otherwise removed as with use of a straw.
The closure part 28 has a pull tab 32 by which it may be grasped to raise it. When the seal between the closure part 28 and the base part 24 i8 s~ddenly broken by this ~pward force, the strain is transferred to the area of the hinge 30 and tend~ to tear the fitment 12 away from its attachment to the upper surface 20 or 20a of the carton.
By the use of the reinforcing patch 22 this ~train is distributed over an area much larger than the area of the flat bottom portion 26, thus preventing the fitment 12 from being torn away. In addition to the force distribution, the ten~ile strength of the added patch material i8 much greater than the 3trength of the carton~coating, thu~ thig new patch material becomes the pximary seal. For example, the typical one mil PE
coating has a tensile strength of five pounds and the tw~ mil patch material has a ~engile strength o fifteen pounds. The ~eal strength of the fitment to th~ carton i8 now a combined total of twenty pounds.
An alternate form of pour fitment i8 indicated at 14 in Figures 4 and 5. It has a base part 24a which in turn ha3 a flat bottom portion 26a adhesively secured to either of the upper surface parts 20 and 20a of the .. , . . ................... . . ~ _ . . .. . . . . ~ . ..
-1313~2 cartons 8 and 10 either partially or entirely cver the reinforcing patch 22. It al90 has a closure part 28a which screws on to the base part 24a.
Thus, the strain of removing the closure part 28a is distributed by the reinforcing patch over an area greater than the area of the flat bottom portion of the fitment 14 thereby preventing it from being torn away.
A fitment 12 is seen in Figures 8-11 which is essentially the same as those shown in Figures 1, 3, 6 and 7 except that it is shown mounted on that part 16 of a carton blank which will become the upper s~rface part of a carton.
It is illustrated to show that the flat bottom portion 24 of the fitment 12 need be secured to the upper surface part 20 of the carton blank and carton only partially over a reinforcing patch 22a. In this situation the patch 22a will lie primarily under the hinge part 30 of the fitment where the greate~t upward strain will be exerted when the closure part 28 is raised to open the fitment 12. In this manner, the patch 22a may be much smaller thus saving C08t and eli~inating the need of a pour hole in it or the need to pierce it for pouring.
The size of the patch must be greater than the actual fitment. If for example it were the same size, the strain at the hinge point would be transferred to the carton coating thus resulting in reduced ~trength.
