DETAILED DESCRIPTION The packaging industry has seen advances in both packaging media and devices that facilitate dispensing and/or provide resealability of a package. For some types of product, especially flowable materials, a trend in packaging media has shifted from the use of rigid materials to more flexible materials. Flexible packaging provides a number of advantages, including handling and shipping advantages.

Another shift has been to the use of plastic spouts or fitments to provide access to the product inside the flexible package. Such fitments generally permit ready access to the product and may also provide resealability of the package to reduce or prevent contamination of the product, leakage, spillage, and so forth.

Fitments include a flange and a rigid, upstanding, tubular spout. Some have a cap or closure attached thereto, or a thread or other connection for receiving the same. Fitments can be formed of a rigid material so that the fitment retains its shape for accessing the interior of the package, receiving the closure, maintaining the closure engaged with the fitment, and so forth. The fitment is mounted to the flexible package by means of the flange. For example, the flange, or a portion thereof, may extend through an opening of the flexible package into the interior thereof, in a manner that maintains the opening in an open configuration, to allow product to move through the fitment.

One challenge with flowable materials such as fluids, particulate solids, and so forth, is that the material may resist flowing from the interior of the flexible package through the fitment, for example when a user attempts to dispense the product. This may be due to factors such as the flowable material blocking the opening, or the nature of the flowable material itself. Powders and other particulate solids, for example, may clump together and/or adhere to interior surfaces of the fitment. Other flowable materials may possess or exhibit non-Newtonian characteristics.

The following description provides several examples that relate to fitments suitable for use with packaging that contains a flowable material. Of course, the fitments provided in these examples may find use with both rigid and flexible packaging, and transcends any material type contained in such packaging. In that regard, in one or more embodiments described below, the fitment generally includes a flange, a spout, and a dispersion member associated with the spout. In some embodiments, the dispersion member acts upon the flowable material as it is exiting the package to break apart any clumps and provide a smooth flow out of the container. FIGURE 1 is an isometric view of a representative packaging system 100 in accordance with the present disclosure. The package system 100 includes a package 105 with an interior compartment 110 for holding a flowable material (not shown). The flowable material may consist of a liquid, powder, solids, particulate solids, or a combination thereof. The package system 100 may also include a fitment 115 which may be coupled to the package 105. In one embodiment, the fitment 115 may be removably coupled to the package 105 or, in an alternative embodiment, the fitment 115 may be fixed to the package 105. The fitment 115 may fluidly communicate with the interior compartment 110 to allow the flowable material to exit the package 105. When the package system 100 is tilted, the flowable material may exit the package 105 through the fitment 115.

Turning now to FIGURE 2, there is shown an isometric view of the fitment 115 described with reference to FIGURE 1. The fitment 115 may have a base 130 enclosed within the package 105 when the fitment 115 is assembled as part of the package system 100. The fitment 115 may further include a flange 125 to position the fitment 115 on the package 105 and a spout 135 extending upward from the flange 125.

In some embodiments, the base 130 may comprise a symmetrical shape. For example, as shown in FIGURE 6, the base 130 may be generally canoe shaped, football shaped, or the like. Referencing again FIGURE 2, the base 130 may be formed of solid material or may include honeycomb or ridges 120 to maintain the shape of the base 130. Ridges 120 may use less material and comprise a cost and/or weight savings. When assembled, the base 130 may rest inside the package 105 and connect the spout 135 to the interior compartment 110. In addition, the base 130 may provide a foundation for the spout 135 to maintain a position of the spout 135 relative to the package 105.

Referring now to the embodiment of FIGURES 2-4, the flange 125 is integrally formed or otherwise connected to the base. In some embodiments, the flange 125 may provide structural stability for the spout 135. For example, the flange 125 may position the spout 135 on an external surface of the package 105. In some embodiments, the flange 125 may provide a stable foundation to support the positioning of the spout 135. A lower surface 175 of the flange 125 may rest on the external surface of the package 105, as shown in FIGURE 4. The flange comprises a generally cylindrical shape. However, the flange 125 may comprise any polygonal or curved shape providing a solid foundation to the spout 135. In some embodiments, the fitment 115 may include an outer wall 145 forming a body 150 of the spout 135. The body 150 may extend perpendicularly or orthogonally the flange 125. In some embodiments, a top surface 160 of the body 150 may define a first plane which may intersect with a plane defined by the flange 125, as shown in FIGURE 2. Therefore, in some embodiments, the top surface 160 of the spout 135 and the flange 125 may form an angular relationship, as will be described in more detail below. Of course, the top surface 160 of the body 150 may be parallel to the flange 125 in other embodiments.

In some embodiments, the body 150 of the spout 135 may form a cylinder. The cylinder may be circular, or as shown, may have a somewhat oval circumference. In alternative embodiments, the body 150 may be any rounded or polygonal tubular shape. In some embodiments, the top surface 160 of the body 150 includes an opening 155 that forms the spout outlet. In some instances, the opening 155 may be at least partially blocked or covered by a baffle 165 formed in the top surface 160. In other embodiments, the baffle 165 may not be coplanar with the top surface 160 and instead may be positioned within the body 150 of the spout 135.

As shown in the cross-sectional view of FIGURE 5, taken along lines 5-5 of FIGURE 3, the baffle 165, in this instance, is co-planar with the top surface 160 of the spout 135. The cross-sectional view in this example shows an integrally formed fitment 115 comprised of the base 130, the flange 125, and the spout 135.

Referring again to the cross-sectional view of FIGURE 4, taken along lines 4-4 of FIGURE 3, the base 130 in some embodiments may include a wall 400 with an inner surface 405 defining a lower passageway 415 there though. The wall 400 may have a polygonal or rounded shape. In the embodiment shown, the wall 400 comprises a cylindrical inner surface 405. In the embodiment shown, the inner surface 405 at the lower end of the base 130 forms a lower opening 490, which can function as the fitment inlet.

In one embodiment, the outer surface 410 of the wall 400 may be cylindrically shaped or, in alternative embodiments, the outer surface 410 may incorporate one or more features such as the canoe-shaped ridges 120 as shown in the embodiment of FIGURE 2. In some embodiments, the base 130 may include a flange 420, which is shown spaced from and below the flange 125. The flange 420 may extend the entire circumference of the wall 400 or sections thereof. In some embodiments, the flange 420 may have a constant thickness and width. In some embodiments, the flange 420 may have a varying thickness and width. In some embodiments, the flange 420 may position the fitment 115 on the package 105.

For example, in some embodiments, the flange 125 includes a body 425 that defines the lower surface 175 of the flange 125 spaced a distance above the flange 420. The body 425 may be substantially planar or may include a variety of shapes and contours. In some embodiments, he body 425 and the flange 420 may aid in the positioning and attachment of the fitment 115 on the package 105. For example, a surface of the package 105 may fit between the flange 420 and the body 425. This may position the fitment 115 on the package 105 and retain the fitment 115 in a fixed position. The fixed position may be an upright position as shown in FIGURE 1 or, in alternative embodiments, may be an angled or rotated position.

In some embodiments, a wall 440 may be coupled to the upper surface 430 of the flange body 425. The wall 440 may be configured to removably couple a cap to the fitment 115. In the embodiment shown, the wall 440 is orthogonal to the upper surface 430 of the body 425 of the flange. In alternative embodiments, the wall 440 may have a concave or convex inner surface 445 such that the inner surface 445 and the flange 125 form either an obtuse or oblique angle. In some embodiments, the wall 440 may have a series of threads 443 on an outer surface 450. The threads 443 could also be positioned on an inner surface 455 or on the flange body 425 itself. In alternative embodiments, the outer surface 450 could incorporate a groove, lip, or other feature. These features, or threads 443, may be configured to mate with a cooperating feature of the cap (see cap 700 in FIGURE 7).

Still referring to FIGURE 4, the spout 135 in some embodiments may extend from the body 425 of the flange 125. In some embodiments, the spout 135 may be substantially orthogonal to the upper surface 430 of the flange 125. In alternative embodiments, the spout 135 may extend at an angle from the upper surface 430 or have an irregular shape. The outer wall 145 of the spout body 155 includes an inner surface 465 defining an upper passageway 475. The upper passageway 475 and lower passageway 415 may define a larger passageway 480 interconnecting the upper opening 155 and the lower opening 490.

In some embodiments, the wall 145 may form a substantially cylindrical shape with an inner diameter along the inner surface 465. In some embodiments, a dispersion member 495 may be positioned in the passageway 480, as shown in FIGURES 4-6. The dispersion member 495 aims to disperse clumps or modules formed within the flowable material and enable the material to easily flow from the interior compartment 110 of the package 105.

The dispersion member 495 may intersect at least a portion of the passageway 480. For example, a length of the dispersion member 495 may vary. In some embodiments, the length of the dispersion member 495 may be equivalent to a diameter of the passageway 480. In other embodiments, the length of the dispersion member 495 may be a ratio or percentage of the diameter of the passageway 480 such that the dispersion member 495 is cantilevered into the passageway 480. In some embodiments, the dispersion member 495 may intersect a middle of the passageway 480. In alternative embodiments, the dispersion member 495 may be offset from a centerline of the passageway 480. In still further embodiments, multiple dispersion members 495 may be positioned in the passageway.

As shown in FIGURES 4 and 5, the dispersion member 495 may have a body 500 with a height h and a width H\ In some embodiments, the height h and width w of the body 500 may be constant. In alternative embodiments, either the height h or the width w may remain constant while the other varies. For example, in the embodiment shown in FIGURE 4, the width w of the dispersion member is constant, but as shown in FIGURE 5, the height h of the dispersion member 495 varies. Similarly, in some embodiments, the width w of the dispersion member 495 may vary but the profile of the dispersion member 495 may remain constant. For example, the dispersion member 495 may have a knife-edge, a triangular cross-section, a trapezoidal cross-section, or another cross-section which may aid in the breakup of clumping material. A pointed or narrow end of the cross-section may face the bottom opening 490.

As briefly stated above, the top surface 160 of the spout 135 and the flange 125 may form an angular relationship. In that regard, the top opening 155 may form a first plane 505 which may extend at an angle a from the upper surface 430 of the flange 125, as shown in FIGURE 5. The position of the first plane 505 may also be described with reference to the cylindrical wall 150 of the spout 135. For example, the first plane 505 may form an angle b with a portion of the cylindrical body of the spout 135. In some embodiments, angle a may be between about 120-150 degrees. In other embodiments, angles a may be approximately 135 degrees. In other embodiments, angle b may be between about 30-60 degrees. In other embodiments, angles b may be approximately 45 degrees. The angle a may also be a factor in predicting material flow. For example, in some embodiments, the opening 155 may increase or decrease as either angle a or angle b increases or decreases. The size of the opening 155 may help determine the viscosity and flow characteristics of the material.

As also briefly stated above, a baffle 165 is formed in the top surface 160 of the spout 135. In that regard, the baffle 165 in some embodiments may have a body 510 which may be co-planar with the first plane 505. In other embodiments, the baffle 165 may protrude from the inner surface 465 and into the passageway 480. The baffle 165 may extend a portion into the passageway 480. For example, the baffle 165 may extend a quarter, halfway, three quarters, or some variation thereof into the passageway 480. The baffle 165 may limit a size of the opening 155. The baffle 165 may also direct a flow of the material held within the interior compartment 110 of the package 105.

The dispersion member 495 may also affect material flow. In some embodiments, the material may clump or congeal into larger lumps which may hinder the flow of the material. In some embodiments, the dispersion member 495 may interrupt the flow of the material and break up the lumps and alter the material from a non-Newtonian flow to Newtonian flow characteristics. The dispersion member 495 may also change the flow of the material. For example, the dispersion member 495 may change the flow from laminar to turbulent to cause the material to break apart and ease into a better flow viscosity and characteristics.

Various parameters of the dispersion member may affect material flow. In some embodiments, the width w of the dispersion member 495 as well as the height h may affect the flow of the material. For example, the width w may be wide enough to disrupt the lumps that form in the material. In some embodiments, the width w may be a ratio of the total area of the passageway 480. In some embodiments, multiple dispersions members 495 may be used to achieve or increase the ratio. In some embodiments, the multiple dispersion members 495 may be parallel, skewed, or orthogonal to each other. The various arrangements of the dispersion members 495 may be based at least in part on the type of material being stored in the packaging system 100.

Similarly, the height h of the dispersion member 495 may affect the flow of the material. As shown in FIGURE 5, the height h of the dispersion member 495 changes along a length of the dispersion member 495. In the embodiment shown in FIGURE 5, the dispersion member 495 has a first height h _\ along a first distance d _\ and a second height /i ₂ along a second distance <¾ _· In some embodiments, the height may be variable across a length of the dispersion member 495 or along the entire dispersion member 495. In other embodiments, the dispersion member 495 may have a fixed height hy along a first portion of a length d _\ of the dispersion member 495 and a variable height h ₂ along the second portion of the length d ₂ of the dispersion member 495.

In some embodiments, the variable height h ₂ may increase along a length of the dispersion member 495. In some embodiments, the dispersion member 495 may extend from a bottom surface 515 of the dispersion member 495 to the baffle member 165. In the embodiment shown in FIGURE 5 and 6, the dispersion member 495 may have a first triangular shape 605 coupled to a substantially rectangular member 610 projecting across an inner diameter of the spout 135

FIGURE 7 is a cross-sectional view through the fitment 115 with a cap 700 affixed thereto. In some embodiments, the he cap 700 may have a series of threads 705 that mate with a series of threads 443 on the fitment 115. The threads 705 may be on an inner wall 710 of the cap 700 or may be on a flange 715 which may accept the wall 440 and screw into the threads 443 of the fitment 115. In alternative embodiments, the cap 700 may snap or otherwise removably affix to the fitment 115.

FIGURES 8A-8D are exemplary alternative embodiments of the dispersion member 495 positioned in the passageway 480. FIGURE 8A shows two parallel dispersion members 495 cantilevered into the passageway 480. FIGURE 8B shows two dispersion members 495 perpendicular to each other. FIGURE 8C shows a hatched pattern of dispersion members 495. FIGURE 8D shows an alternative hatched pattern of the dispersion members 495.

In each embodiment, the dispersion members 495 may be co-planar, and in some instances, intersect. In alternative embodiments, the dispersion members 495 may be positioned in different planes within the passageway 480 and may not intersect. In still further embodiments, the dispersion members 495 may not be perpendicular to the inner surface 465 of the passageway 480. For example, the dispersion member 495 may angularly span the passageway 480.

In some embodiments, multiple dispersion members 495 may be present in different planes. For example, the patterns shown in FIGURES 8A-8D, or alternative patterns, may repeat in different planes such that from a top down perspective you would only see the number of dispersion members 495 shown, but the actual number may be a multiple of that. For example, FIGURE 8A may have four dispersion members 495 wherein two sets of dispersions members 495 are stacked. FIGURES 9A-9D show a variety of cross-sections of the dispersion member 495. For example, in FIGURE 9A, the dispersion member 495a has a square cross-section. In FIGURE 9B, the dispersion member 495b has a knife-like cross-section. In FIGURE 9C, the dispersion member 495c has a triangular cross-section. In FIGURE 9D, the dispersion member 495d has a polygonal cross-section. Other cross-sectional shapes may also be used. In some embodiments, if more than one dispersion member 495 is present, the dispersion members 495 may have the same or different cross-sections.
