FIGS. 1 and 2 show a first flexible container 10 for containing a quantity of pourable product. FIG. 1 is front view; the rear view of the flexible container 10 is identical, but mirrored. The pourable product can be a liquid, a powder, a plurality of discrete pieces, or any combination thereof. The pourable product can be food product or non-edible product. With respect to possible alternative pourable food products, the pourable product in the first flexible container 10 can be a liquid such as ketchup or sauce or cream cheese, or a powder such as salt or pepper or other spices, or a plurality of discrete pieces such as candy pieces or crackers or potato chips. These exemplary pourable food products are set forth as examples and illustrations and not as limitations.
The first flexible container 10 is in the form of a bag 12. As used herein, “bag” refers to any flexible container operable to hold a pourable product such as, by example and not limitation, a potato-chip style bag, a condiment packet, a fruit/vegetable sac, or a rock salt style bag. Alternative embodiments of the first flexible container 10 can take the form of a packet or a pouch or a sack. The bag 12 has a first closed end 14 and a second closed end 16 and a wall 18. The wall 18 extends between the first closed end 14 and the second closed end 16 to define a closed cavity. The bag 12 includes four corners 20, 22, 24, 26 defined at the first and second ends 14, 16. Alternative embodiments of the invention may include a bag having two corners at one end and an opposite end being rounded or two rounded ends.
The first flexible container 10 also includes a plurality of tearable score lines 28, 30 spaced from one another to define a plurality of differently configured intended openings 32, 34 in the bag 12. In alternative embodiments of the invention, the plurality of score lines may include more than two score lines to define more than two intended openings in the bag. In the first flexible container 10, the opening 32 is a pour spout and the opening 34 is a display opening. The leader lines extending from the numerals 32 and 34 are dashed in FIGS. 1 and 2 because material has not been separated from the bag 12 to define the openings 32, 34.
The score line 28 extends about a portion 38 of the second closed end 16 to isolate the portion 38 from a first remainder of the bag 12. The corner 24 is included with the portion 38 of the second closed end 16. The score line 28 also extends about a portion 40 of the wall 18. The first remainder of the bag 12 remains after the portions 38 and 40 have been removed. The path followed by the score line 28 defines the first intended opening to the closed cavity, the pour spout 32.
The score line 30 is spaced from the score line 28 and extends about a portion 42 of the wall 18 to isolate the portion 42 from a second remainder of the bag 12. The score line 30 also extends about a portion 36 of the second closed end 16. The second remainder of the bag 12 remains after the portions 36, 38, 40 and 42 have been removed. The path followed by the score line 30 defines the second intended opening to the closed cavity, a display opening 34. The display opening 34 is larger than the pour spout opening 32. When the display opening 34 is formed, the portions 38, 40 which define the pour spout 32 are also removed from the bag 12. Both of the score lines 28 and 30 extend along endless paths, defining complete circles.
The first flexible container 10 can be opened in several ways. Either closed end 14, 16 may be opened to gain access to the pourable product in the closed cavity. Alternatively, either the pour spout 32 or the display opening 34 can be opened. For example, if the user of the first flexible container 10 desires to pour the pourable product from the first flexible container 10, the user can directly grasp the corner 24 with one hand and directly grasp the portion 36 of the second closed end 16 with the other hand and twist the corner 24 and the portion 36 relative to one another. The twisting will cause the bag 12 to tear along the score line 28 and separate the corner 24 from the first remainder of the bag 12, thus defining the pour spout opening 32.
Alternatively, if the user of the first flexible container 10 desires to expose the pourable product in the first flexible container 10, the first flexible container 10 can function like a serving dish, such as a bowl or platter. The user can directly grasp the portion 36 with one hand and directly grasp the corner 26 with the other hand and twist the portion 36 and the corner 26 relative to one another. The twisting will cause the bag 12 to tear along the score line 30 and separate both the corner 24 and the portion 42 from the second remainder of the bag 12, thus defining the display opening 34.
As result, the first flexible container 10 allows a user to use and/or consume the pourable product in different ways. The pour spout 32 can be a desirable opening if the user will be holding the first flexible container 10. The display opening 34 can be a desirable opening if the first flexible container 10 is placed on a surface. Furthermore, the first flexible container 10 allows a user to use and/or consume the pourable product in different ways during use and/or consumption. For example, the pour spout 32 can be opened initially and then the display opening 34 can be opened subsequently if the conditions of use and/or consumption change.
Each of the score lines 28, 30 include a pair of sub-score lines to enhance control over the tear of the bag 12. For example, the score line 28 includes a primary score line 44 and back-up score line 46. The lines 44, 46 are closely spaced to one another and extend substantially parallel to one another. The line 44 is the intended line of tear. However, during tearing, the line of tear may depart from the line 44. In such a circumstance, the line of tear will intersect the line 46 and follow the line 46. As a result, the likelihood of over-tearing is reduced.
FIG. 5 shows an embodiment of the score line 30. The bag 12 is formed from plastic and is multi-laminate. The score line 30 includes a primary score line 48 and back-up score line 50. The lines 48 and 50 can be formed with a die or with a laser or with any other score line-forming method/device known in the art. The exemplary lines 48 and 50 do not extend completely through the bag 12 to increase the likelihood that the pourable product in the bag 12 will remain fresh.
In the first flexible container 10, the second score line 30 encircles the first score line 28. FIGS. 3 and 4 show a second flexible container 10a in the form of a packet 12a having a different arrangement of score lines. The second flexible container 10a is operable to contain a quantity of pourable product, such as powder 54a, a liquid 56a, a plurality of discrete pieces 58a, or any combination thereof. A “liquid” includes any non-solid material regardless of viscosity. The packet 12a with a first closed end 14a and a second closed end 16a and a wall 18a. The wall 18a extends between the first closed end 14a and the second closed end 16a to define a closed cavity. The packet 12a includes four corners 20a, 22a, 24a, 26a defined at the first and second ends 14a, 16a. The second flexible container 10a also includes a plurality of tearable score lines 28a, 30a spaced from one another to define a plurality of differently configured intended openings 32a, 34a in the packet 12a. In the second flexible container 10a, the opening 32a is a pour spout and the opening 34a is a display opening. Only the score line 28a extends along an endless path to define a complete circle. The score line 30a includes an appreciable starting point and ending point, both disposed along the end 16a. 
The first and second flexible containers 10, 10a demonstrate that the teachings of this application can be practiced in numerous ways. For example, in the first flexible container 10, the openings 32, 34 overlap since the score line 30 encircles the score line 28. In the second flexible container 10a, the score lines 28a, 30a do not overlap. As a result, a portion 38a can be retained with respect to the bag 12a while the portion 42a is removed from the bag 12a. The portions 38a and 42a are spaced from one another. In addition, the first end closed 14a extends substantially parallel to said second closed end 16a in the second flexible container 10a. The first closed end 14 extends substantially perpendicular to the second closed end 16 in the first flexible container 10.
FIG. 6 shows a third flexible container 10b operable to contain a quantity of pourable product, such as powder 54b, a liquid 56b, a plurality of discrete pieces 58b, or any combination thereof. The flexible container 10b includes a bag 12b having a first closed end 14b and a second closed end 16b extending substantially parallel to the first closed end 14b. The bag 12b also includes a wall 18b extending between the first closed end 14b and the second closed end 16b to define a closed cavity.
The bag 12b also includes a tearable score lines 28b, 30b defining an intended openings directly to the closed cavity. The score line 30b divides the wall 18b into a first portion 52b engaged with both of the first closed end 14b and the second closed end 16b and a second portion 42b spaced from both of the first closed end 14b and the second closed end 16b. The tearable score line 30b is exposed and directly graspable. The tearable score line 30b extends along a closed path and is exposed along all of the closed path. The tearable score line 30b is the only link between the first portion 52b and the second portion 42b. As a result, the bag 12b can be permanently converted into a serving dish such a bowl or a platter. The bag 12b requires no extraneous overlay or other link between the portions 42b, 52b, to render the portion 42b a re-closable lid member to the bag 12b, making the bag 12b less costly and easier to open than bags in the prior art.
As set forth above, the flexible container 10b can contain a pourable food product. If the food product is a liquid, the liquid is flowable through an aperture formed when the tearable score line 30b is torn and the second portion 42b is permanently separated from the first portion 52b. In one example, the bag 12b may contain a quantity of ketchup desirable for an event, such as a picnic. Instead of transporting a large plastic bottle of ketchup, a user may acquire a bag 12b with a smaller quantity of ketchup. The bag 12b can be opened like a serving dish by removing the portion 42b from the portion 52b, the ketchup evacuated from the bag 12b through a display opening 34b during the event, and the bag 12b disposed after the event.
If the quantity of pourable food product is a plurality of discrete pieces, the second portion 42b can be larger than each of the plurality of discrete pieces. In one example, the bag 12b may contain a quantity of potato chips desirable for an event, such as a party. The portion 42b can be sized to allow a user to grasp a plurality of potato chips at one time and evacuate the potato chips from the bag 12b. 
The path followed by the tearable score line 30b includes first and second hastate portions 60b, 62b. Alternative embodiments of the invention may only include one hastate portion or may not include a single hastate portion. The hastate portions 60b, 62b provide locations to initiate a tear of the score line 30b. A user of the bag 12b can grasp one side of the score line 30b, the portion 52b, with one hand and grasp the other side of the score line 30b, the portion 42b, with the other hand. Pinching the grasped portions 42b and 52b and pulling apart can result in the score line 30b being torn.
FIG. 7 shows a fourth flexible container 10c operable to contain a quantity of pourable product. The flexible container 10c is the form of a bag 12c having a first closed end 14c and a second closed end 16c extending substantially parallel to the first closed end 14c. The bag 12c also includes a wall 18c extending between the first closed end 14c and the second closed end 16c to define a closed cavity. The bag 12c also includes a tearable score lines 28c, 30c defining an intended opening directly to the closed cavity. The tearable score line 30c includes a primary score line 48c and back-up score line 50c closely spaced to one another and extending substantially parallel to one another.
The flexible container 10c also includes a longitudinal seam 64c closing the wall 18c transverse to the first closed end 14c and the second closed end 16c. The tearable score line 30c crosses the longitudinal seam 64c. Thus, the score line 30c is disposed on the side of the bag 12c that is generally the back side. First and second tabs 66c, 68c are formed in the longitudinal seam 64c. The tabs 66c, 68c are contiguous with the tearable score line 30c and can be engaged to initiate a tear in the score line 30c. The tabs 66c, 68c can be aligned with the primary score line 48c and can be helpful to accomplish complete tearing of the score line 30c across the seam 64c. The tab 66c can be pulled in a direction 70c to tear the score line 30c across the seam 64c and the tab 68c can be pulled in a direction 72c to tear the score line 30c across the seam 64c. 
The foregoing invention has been described in accordance with the relevant legal standards, thus the description is exemplary rather than limiting in nature. Variations and modifications to the disclosed embodiment may become apparent to those skilled in the art and do come within the scope of the invention. Accordingly, the scope of legal protection afforded this invention can only be determined by studying the following claims.
