The present invention relates to pouch-type flexible beverage containers (“pouches”) and, more particularly, to internal structures for such beverage containers to prevent collapse of the containers when grasped and/or to facilitate mixing ingredients within the containers.
Liquids, such as beverages, detergents and pesticides, as well as many other liquids requiring airtight seals are packaged and contained in pouch-type containers. These containers typically include coverings or caps removably attached to opening portions, such as spouts, of the containers. A user can remove the cap from a container to access liquid contained therein and subsequently replace and reseal the cap to the container to maintain freshness of remaining liquid.
Protein powder and other supplement drinks are popular among bodybuilders and other exercise enthusiasts. Typically, supplement powder and a liquid, such as water or milk, are mixed in a blender and then poured into a container for consumption, or the power and liquid are mixed within the container by shaking the container. Some supplement drink consumers prefer to consume such drinks within certain timeframes, such as within 60 minutes (a so-called “golden window”) after exercising.
Many consumers prefer to keep supplement powder dry until they are ready to consume it. Thus, such consumers prefer to mix dry supplement powder with liquid just before they wish to drink the mixture. Several factors motivate delaying the addition of the liquid until just before the supplement is to be consumed. For example, cold liquid may be added to the powder, whereas a pre-mixed drink is likely to have warmed to an unappetizing temperature by the time a consumer is ready to drink it. Furthermore, pouches of dry powder are much lighter and less bulky than pouches that contain powder and liquid. In addition, some health-conscience consumers prefer not to purchase pre-mixed drinks, because pre-mixed drinks typically contain preservatives, and these consumers prefer to avoid these preservatives.
Although some consumers purchase supplement powder in large, multi-serving containers and scoop a single serving quantity into their own beverage containers when needed, other consumers prefer to purchase single-serving pouch-type beverage containers that are pre-filled with dry supplement powder and add liquid just before consuming a drink. In either case, the supplement powder needs to be mixed with the liquid. However, most supplements do not mix well with water. For example, some supplements tend to clump, foam or fizz. Milk avoids most of the mixing problems. However, many consumers prefer to avoid calories that would be provided by the milk.
Although pouch-type beverage containers have several advantages over rigid containers, pouch-type beverage containers become difficult to drink from as they become less than full. The pouch collapses, leaving little or nothing to solidly grasp, thereby making the containers awkward to drink from and difficult to shake, so as to mix supplement that has settled after an initial mixing. Furthermore, as the pouch collapses, it traps supplement in interior crevices and pockets and clinging to interior walls of the container. In some cases, a less-than-full pouch folds or flops, making it difficult to access some of the contents.
An embodiment of the present invention provides a fitment for a flexible container. The flexible container has walls and defines an opening. The fitment includes a mounting structure, a spout coupled to the mounting structure, at least one support structure extending from the mounting structure and a grasp structure. The mounting structure is configured to be sealingly coupled to the flexible container about the opening, thereby defining an interior of the flexible container. The spout defines a fluid channel through the mounting structure. The spout is configured to be in fluid communication with the interior of the flexible container. The at least one support structure extends from the mounting structure, generally parallel to an axis extending through the fluid channel of the spout. The at least one support structure is configured to extend into the interior of the flexible container. The grasp structure extends along a loop in a plane generally perpendicular to the axis passing through the fluid channel of the spout. The grasp structure is attached to each of the at least one support structure. The grasp structure is configured to be inserted into the interior of the flexible container and there extend proximate an inside perimeter of the flexible container. The grasp structure provides a skeletal structure against which the walls of the flexible container may be pressed when the flexible container is grasped.
The fitment may also include a first spacing member extending from a first point along the grasp structure to an approximately diametrically opposite point along the grasp structure. The first spacing member is not directly attached to the mounting structure.
The first spacing member may extend generally along an arc in a plane generally perpendicular to the plane of the loop.
The fitment may also include a first pad and a second pad. The first pad may be attached to the grasp structure proximate the first point along the grasp structure. The first pad may be oriented generally parallel to the axis passing through the fluid channel of the spout. The second pad may be generally parallel to the first pad. The second pad may be attached to the grasp structure proximate the diametrically opposite point along the grasp structure.
The at least one support structure may include at least a first support structure and a second support structure. The first support structure may be attached to the grasp structure approximately equidistantly between the first point along the grasp structure and the diametrically opposite point along the grasp structure. The second support structure may be attached to the grasp structure approximately diametrically opposite the first support structure.
The fitment may also include a second spacing member extending from where the first support structure is attached to the grasp structure to where the second support structure is attached to the grasp structure. The second spacing member is not directly attached to the mounting structure.
The second spacing member may extend generally along an arc in a plane generally perpendicular to the plane of the first spacing member.
Each of the first support structure and the second support structure may define an outwardly-facing concave portion proximate where the respective support structure is attached to the grasp structure.
The fitment may also include a mixing structure. The mixing structure may be mechanically coupled to the first support structure, the second support structure and the grasp structure. The mixing structure may be configured to extend into the interior of the flexible container. The mixing structure may be disposed so as to promote mixing of contents in the interior of the flexible container. The mixing structure may be disposed so as to interfere with smooth flow of fluid introduced through the spout in a direction toward the interior of the flexible container.
The grasp structure may extend along a generally oval-shaped loop having a major diameter at least about 1½ times as long as a minor diameter of the generally oval-shaped loop.
The flexible container may have a predetermined internal depth. The mounting structure, the at least one support structure and the grasp structure may be configured such that the grasp structure is spaced from the mounting structure along the axis of the fluid channel of the spout a distance of between about ¼ and about ¾ the internal depth of the flexible container.
The flexible container may define a waist portion located a predetermined distance from the opening of the flexible container. The mounting structure, the at least one support structure and the grasp structure may be configured such that the grasp structure is spaced from the mounting structure along the axis of the fluid channel of the spout a distance approximately equal to the predetermined distance.
The fitment may be attached to the flexible container.
The fitment may include a mixing structure. The mixing structure may be mechanically coupled to the mounting structure. The mixing structure may be configured to be disposed in the interior of the flexible container. The mixing structure may be disposed so as to promote mixing of contents in the interior of the flexible container. The mixing structure may be disposed so as to interfere with smooth flow of fluid introduced through the spout in a direction toward the interior of the flexible container.
The mixing structure may include a plurality of interconnected members collectively defining a plurality of apertures through the mixing structure.
An embodiment of the present invention provides a fitment for a flexible container. The flexible container has walls and defines an opening. The fitment includes a mounting structure, a spout coupled to the mounting structure, at least one support structure extending from the mounting structure and a mixing structure attached to the at least one support structure. The mounting structure is configured to be sealingly coupled to the flexible container about the opening, thereby defining an interior of the flexible container. The spout defines a fluid channel through the mounting structure. The spout is configured to be in fluid communication with the interior of the flexible container. The at least one support structure extending from the mounting structure, generally parallel to an axis extending through the fluid channel of the spout. The at least one support structure is configured to extend into the interior of the flexible container. The mixing structure is configured to be disposed in the interior of the flexible container. The mixing structure is disposed so as to promote mixing of contents in the interior of the flexible container. The mixing structure is disposed so as to interfere with smooth flow of fluid introduced through the spout in a direction toward the interior of the flexible container.
The mixing structure may include a plurality of interconnected members collectively defining a plurality of apertures through the mixing structure.
The flexible container may have a predetermined internal depth. The mounting structure, the at least one support structure and the mixing structure may be configured such that the mixing structure is spaced from the mounting structure along the axis of the fluid channel of the spout a distance of between about ¼ and about ¾ the internal depth of the flexible container.
The flexible container may define a waist portion located a predetermined distance from the opening of the flexible container. The mounting structure, the at least one support structure and the mixing structure may be configured such that the mixing structure is spaced from the mounting structure along the axis of the fluid channel of the spout a distance approximately equal to the predetermined distance.
The fitment may be attached to the flexible container.
Yet another embodiment of the present invention provides a container assembly. The container assembly includes a container and an insert assembly coupled to the container. The insert assembly includes a mounting element, a spout element extending from the mounting element and a flow-through structure extending from the mounting element. The flow-through element is disposed in fluid communication with the spout element. The flow-through element is configured to promote mixing of contents in the interior of the container. The flow-through element is configured to impinge upon at least a portion of a flow of fluid received from the spout to create turbulence within the flow of fluid.
The invention will be more fully understood by referring to the following Detailed Description of Specific Embodiments in conjunction with the Drawings. The drawings are not necessarily to scale, emphasis instead being placed upon illustrating principles of various embodiments of the innovation.
Embodiments of the present invention address problems associated with grasping pouch-type containers and mixing contents of such containers. Embodiments of the present invention include fitments configured for insertion into pouch-type flexible containers and associated flexible containers.
In some embodiments, the fitment includes a skeleton (also referred to herein as a grasp structure) within the pouch, against which flexible walls of the container can be pressed when a user grasps the outside of the pouch. The skeleton provides a structure against which the user can apply grasping force, thereby preventing significant collapse of the pouch. In some embodiments, the fitment includes structures that are spaced apart a distance approximately equal to an inside dimension of the pouch. The structures are configured to resist deflection toward each other.
In some embodiments, the fitment includes a mixing structure that resides within the pouch and facilitates mixing contents, such as powders and liquids, in the pouch. The mixing structure interferes with smooth flow of the contents within the container, such as when the container is shaken or liquid is added to the container, thereby breaking up clumps of the powder and often creating turbulence in the liquid, which enhances mixing. The mixing structure does not, however, completely prevent flow of the contents within the container.

As shown in
A spout 406 is coupled to the mounting structure 402. The spout 406 may be threaded to accept a complementarily threaded cap (not shown). The spout 406 defines a fluid channel 408 through the mounting structure 402 and into an interior 800 of the flexible container 100. Thus, the spout 406 is in fluid communication with the interior 800 of the flexible container 100. An axis 410 extends through the fluid channel 408 of the spout 406.
Two support structures 412 and 414 extend below the mounting structure 402, generally parallel to the axis 410. As can be seen in
The fitment 400 includes a grasp structure 416, best seen in
The grasp structure 416 is attached to each of the support structures 412 and 414. When the fitment 400 is installed in the flexible container 100, the grasp structure 416 extends proximate an inside perimeter of the flexible container, for example as indicated at 802 and 804 (
For example, the flexible container 100 may define a waist portion 806 located a predetermined distance 808 from the opening 106 of the flexible container 100. The waist portion 806 is narrower than vertically adjacent portions of the flexible container 100. The mounting structure 402, the support structures 412 and 414 and the grasp structure 416 are configured such that the grasp structure 416 is spaced from the mounting structure 402 along the axis 410 a distance approximately equal to the distance 808. Consequently, the vertical position of the grasp structure 416 approximately corresponds with the vertical position of the waist portion 806. This positioning allows the flexible container 100 to have portions (“shoulders” 810 and “hips” 812) that are larger, and therefore have greater capacities, than the waist portion 806.
Although the flexible container 100, with the fitment 400 installed, may be grasped anywhere, the flexible container 100 exhibits better grasping performance, i.e., the walls 102 and 200 collapse less, when a user grasps the flexible container 100 about the waist portion 806. Typically, a user grasps the flexible container 100 across the major diameter of the grasp structure 416, as indicated schematically by arrows 420 (
The grasp structure 416 is relatively stiff, although it may resiliently deflect somewhat inward under urging of a user's grip. The grasp structure 416 may be dimensioned and/or made of a material selected to minimize or control the amount of deflection experienced by the grasp structure 416 or the amount of force required to deflect the grasp structure 416 when a user grasps the flexible container 100.
A first spacing member 424 (best seen in
The first spacing member 424 may be straight or, as shown in
To provide tactile feedback and a surer grip, two pads 428 and 430 may be attached to the grasp structure 416 at the two points 426 (and not visible) where the spacing member 424 is attached to the grasp structure 416. The pads 428 and 430 may be oriented generally parallel to the axis 410 and, more specifically, parallel to the walls 102 and 200 of the flexible container 100. The two pads 428 and 430 may be generally parallel to each other. Each pad 428 and 430 may include raised features 430 and/or a depression 432 for tactile feedback and better grip.
The support structures 412 and 414 may be attached to the grasp structure 416 at two respective points 434 and 436 (best seen in
Each support structure 412 and 414 may define an outwardly-facing concave portion 438 and 440 (best seen in
A second spacing member 425 (best seen in
The second spacing member 425 may be straight or, as shown in
The flexible container 100 may have a predetermined internal depth 814 (
The fitment 400 may be molded of a polymeric or other suitable material or fabricated by another suitable process. Exemplary polymeric materials include polypropylene, polystyrene, polystyrene-acrylonitrile, acrylonitrile-butadiene-styrene, styrene-maleic anhydride, polycarbonate, polyethylene terephthalate, polyvinyl cyclohexane and blends thereof.
Some embodiments of the fitment 400 include a mixing structure, with or without a grasp structure 416. This description is of a fitment 400 that includes a grasp structure 416 and a mixing structure. However, other embodiments may omit the grasp structure 416. Similarly, some embodiments include a grasp structure 416, without a mixing structure.
A mixing structure 600 (best seen in
The first and second spacing members 424 and 425 may, but need not, be parts of the mixing structure 600. In the embodiment shown in
The mixing structure 600 is mechanically coupled to the mounting structure 402 by the support structures 412 and 414. The mixing structure 600 is configured to be disposed in the interior of the flexible container 100, as shown in
As noted, the flexible container 100 may have a predetermined internal depth 814 (

As can be seen in
The insert assembly 912 is also configured to agitate the fluid 920 as it enters the container 910, thereby causing the fluid 920 and the powdered material 916 to mix with each other. For example, the insert assembly 912 includes a flow-through structure 922 extending into the internal volume 914 of the container 910 and substantially aligned with a longitudinal axis 924 of the insert assembly 912. As a user adds fluid 920, such as water, to the container 910 via the opening 918, the fluid 920 flows through and/or past the flow-through structure 922 which, in turn, agitates or induces turbulent flow in the fluid 920. As the turbulent fluid exits the flow-through structure 922, the fluid 920 mixes with the powdered material 916 contained within the internal volume 914. Once mixed, the user can then drink the mixture from the container 910 via the insert assembly 912.
While the insert assembly 912 can be manufactured in a variety of ways utilizing a variety of materials, in one embodiment, a manufacturer injection molds the insert assembly 912 from a suitable plastic material. The manufacturer can then secure the insert assembly 912 to the container 910 utilizing a variety of fixation materials and methods, as are well known in the art.
The mounting element 1013 is configured to be coupled to the container 1010. For example, as illustrated in
The grasping assembly 1017 is configured to provide a level of rigidity to the container 1010 to allow a user to readily grasp and hold the container 1010. For example, the grasping assembly 1017 can include a first grasping element 1050 extending longitudinally from the mounting element 1013 and a second grasping element 1052 extending longitudinally from a distal portion of the flow-through structure 1022. In use, a user can grasp the container 1010 along a direction that is substantially parallel to walls 1027 and 1029 to engage the first and second grasping elements 1050 and 1052.
The spout element 1015 is configured to allow fluid to both enter and exit the volume 1014 of the container 1010. For example, the spout element 1015 defines an opening 1018 that extends along a longitudinal axis 1024 of the insert assembly 1012 between a location outside of the container 1010 and the volume 1014 defined by the container 1010. In one arrangement, the spout element 1015 includes a set of external threads 1026 disposed about an outer perimeter of the spout element 1015. The set of threads 1026 is configured to interface with a corresponding set of complementarily-shaped internal threads of an associated cover or cap 1028. Interaction between the set of external threads 1026 on the spout element 1015 and the set of internal threads of the cover 1028 provides a releasable seal between the cover 1028 and the container 1010.
The flow-through structure 1022 extends from the mounting structure 1013 into the volume 1014 defined by the container 1010. While the flow-through structure 1022 can extend into the volume 1014 in a variety of ways, in one arrangement as illustrated in
As indicated above, the flow-through structure 1022 is configured to induce turbulence to fluid added to the container 1010 as the fluid flows from the spout element 1015, past the flow-through structure 1022, and to the container volume 1014. While the flow-through structure 1022 can be configured in a variety of ways, as illustrated in
Based upon the configuration of the flow-through structure 1022, the insert provides substantially automatic mixing of the fluid 1020 and a powdered material 1016 disposed within a container 1010.
The grasping assembly 1217 is configured to provide a level of rigidity to an associated container to allow a user to readily grasp and hold the container. For example, the grasping assembly 1217 can include a first grasping element 1250 and a second grasping element 1252 disposed at a proximal end of the flow-through structure 1222. In use, in the case where the container is configured as a pouch, a user can grasp, as schematically indicated by arrows 1262 (
As illustrated, the flow-through structure 1222 is configured as a basket structure. For example, the flow-through structure 1222 includes substantially lateral structures 1234 that extend from the grasping assembly 1217 as well as longitudinal structures 1235. With such a configuration, the lateral and longitudinal structures 1234 and 1235 are configured to impinge upon at least a portion of a flow of the fluid received via the spout element 1215 to create turbulence within the fluid.
Also as illustrated, the flow-through structure 1222 is disposed at a distance from the mounting structure 1213 by a support structure 1270. For example, the support structure 1270 is configured as a set of supports 1271 that extend longitudinally from the mounting structure 1213 and that couple to a distal end of the flow-through structure 1222. Further, the flow-through structure 1222 can be disposed within a container at a variety of distances from a top or upper surface of the container. For example, in one arrangement, the flow-through structure 1222 is disposed from the top surface of the container at a distance of approximately ⅓ a total length of the container. Such positioning can optimize mixing of a fluid introduced to the container with a powdered material carried therein.
As illustrated, the flow-through structure 2322 is configured as a grid or mesh structure. For example, the flow-through structure 2322 includes substantially lateral structures 2334 and longitudinal structures 2335 that extend within the grasping assembly 2317. With such a configuration, the lateral and longitudinal structures 2334 and 2335 are configured to impinge upon at least a portion of a flow of the fluid received via the spout element 315 to create turbulence within the fluid.
The flow-through structure 2322 is disposed at a distance from the mounting structure 2313 by a support structure 2370. For example, the support structure 2370 is configured as a set of flared supports 2371 that extend longitudinally from the mounting structure 2313 and that couple to the grasping assembly 2317. Further, the flow-through structure 2322 can be disposed within a container at a variety of distances from a top or upper surface of the container. For example, in one arrangement the flow-through structure 2322 is disposed from the top surface of the container at a distance of approximately ⅓ a total length of the container.
As indicated above, when a user adds fluid to a container via an insert assembly, the fluid contacts an associated flow-through structure which creates turbulence within the fluid stream and causes mixing of the fluid with powdered material carried within the container. However, in certain cases the powdered material may not completely mix with the fluid introduced to the container. As a result, the resulting mixture can include clumps of non-dissolved powder that can be consumed by the user. To minimize the delivery of clumps of non-dissolved powder to the user, in one arrangement, the insert assembly includes a particle filter configured to limit or prevent the clumps from entering the spout element of an associated insert assembly.
