DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
[0058] Embodiments of the present invention provide a system and method for meeting market demand for better constructible utensils. The following description is presented to enable one of ordinary skill in the art to make and use the invention and is provided in the context of a patent application and its requirements.
[0059] Various modifications to the preferred embodiment and the generic principles and features described herein will be readily apparent to those skilled in the art. Thus, the present invention is not intended to be limited to the embodiment shown but is to be accorded the widest scope consistent with the principles and features described herein.
[0060] It should be noted that the Figures include specific shapes, paths, and arrangements of scores used to facilitate formation of three dimensional bowls as a part of a body is folded. The scores have been illustrated to accurately present representative suitable score paths for the particular utensil type and application, particularly with respect to location, arrangement, and placement.
[0061] The constructible utensils disclosed herein are generally representative of a wide range of constructible utensils, some of which have been illustrated and described in related patents and patent applications. These related patents and patent applications, all of which have the same inventor, include, but are not limited to, U.S. Pat. No. 8,210,381 issued Jul. 3, 2012 (attorney docket 7001), U.S. Pat. No. 9,131,793 issued Sep. 15, 2015 (attorney docket 7012), U.S. Pat. No. D646,529 issued Oct. 11, 2011 (attorney docket 7003), and U.S. Pat. No. D651,480 issued Jan. 2, 2012 (attorney docket 7004); and U.S. patent application Ser. No. 13/357,557 filed Jan. 24, 2012 (attorney docket 7006), 61/699,808 filed Sep. 11, 2012 (attorney docket 7009), 61/699,787 filed Sep. 11, 2012 (attorney docket 7010), 61/712,610 filed Oct. 11, 2012 (attorney docket 7011), 61/794,613 filed Mar. 15, 2013 (attorney docket 7013), and 61/794,880 filed Mar. 15, 2013 (attorney docket 7014), all of which patents and patent applications are hereby expressly incorporated by reference in their entireties into the present patent application.
[0062] In some cases, a preferred embodiment includes environmentally friendly materials, which often include paper and paper-like substances. For a utensil, it is the case that the foodstuff may have a significant moisture content. To enhance longevity in terms of preserving structural integrity and strength over the serving/portion size, moisture resistance is important in some implementations. Such utensils may be processed to enhance function (e.g., coated with environmentally appropriate material) to resist premature degradation during use (e.g., a moisture-barrier), or may be manufactured of a moisture-barrier material (e.g., calcium carbonate or the like), collectively a coating, whose inherent characteristic or other moisture protection system is referred to as moisture-barrier property.
[0063] Some preferred embodiments include a paperboard sheet material. In some of the descriptions, there are certain score lines that are specifically set forth to be close to, but spaced away from, an edge of a body or body element of a constructible utensil. For some materials, these scores break down fiber used in the body and could increase moisture absorption. Spacing a terminating end of these score lines away from the physical edge improves moisture absorption resistance.
[0064] The preferred embodiments use sustainable tree-based wood fibers due to improved material properties. In some applications, and as additional materials are developed, other materials (such as shorter fibers from other plants or mineral-based substrates) may be used in lieu of tree-based wood fibers. Additionally, the preferred embodiments describe implementations that include multiple curved scores, including multiple curved scores that “bend” inwardly towards each other. Some implementations may include other configurations, including a single curved implementation that produces a bowl when folded along this score.
[0065] Some of the disclosed embodiments include configuration changes to a basic constructible single-use taster.
[0066] The constructible taster includes a generally “bullet” shaped perimeter having a longitudinal axis about which the constructible taster is generally symmetric. The perimeter is about 1.25 inches wide and about 3.125 inches long (the “bullet” shaped perimeter including a generally rectangular body that is about 1.25 inches x about 2.5625 inches and a semi-disk at one end of the rectangle having a radius of about 0.5625 inches). A handle portion is joined to a functional end with handle portion including a short handle score extending along the longitudinal axis and joining a pair of curved scores extending from lateral edges of the functional end located at a distal end (e.g., opposite of the handle portion at a proximal end). In some implementations the handle score may be omitted, its function provided by an extension of one or more of the curved scores extending towards the proximal end from the distal end. Folding/deforming the proximal end along the handle score (or handle score substitute) induces the deformation of the functional end about the one or more curved scores to create a three-dimensional structure (generally described as arched or bowl-shaped), which adds strength/rigidity and function, such as retaining low-viscosity foodstuff.
[0067] The tasters are generally small, and the constructible taster is particularly configured to reduce material use while providing efficient operation. A size and shape of a bowl formed in the constructible taster at the distal end is determined, again, by the arrangement of the scores with respect to the body and its structures. For example, in a preferred embodiment, the scores are close to lateral edges of the body near the distal end (without reaching the edge to improve mouth feel by reducing sharp edges), and converge to a central fold axis near the proximal end and produce the desired bowl shape. The scores are gentle and convex with respect to the fold axis and curve over almost the entire length of the rectilinear body and do not meet until very close to the edge. For purposes of this application in the context of a taster, the scores converge within 33% of the length of the body element from the handle end and most preferably within 10% of the length from the handle end. At the other end, the scores reach near the lateral edges at points greater than 50% of the length and most preferably at points greater than 75%.
[0068] Included with the constructible taster are informational indicia (e.g., specifically positioned dots) that identify a preferred location for squeezing/deforming the handle portion. (E.g., bend-to-touch dots, which recreate the desired deformation in the handle to help optimize formation of the functional element.) Preferably, these indicia are placed near where the scores converge, in this case, towards the proximal end of the body, so that the body gradually distorts along scores generally over the entire length.
[0069] In some embodiments, it will be desirable to provide some type of mechanism to maintain the lateral edges of the body (e.g., near the indicia) in a generally folded arrangement to preserve a desired minimum capacity/shape to the formed bowl (and to maintain those lateral edges extending upwards to be easily grasped to permit the constructible taster to be picked up from a work surface, especially with the bowl shape retained). The material selection of the body and the depth and nature of the formation of the scores are one way to provide for a retaining force resisting unfolding when a folding force is removed. In other embodiments, some type of tacky adhesive or interconnecting tabs may be used to hold the lateral edges together and the body in the folded mode.
[0070] The incorporated patents and patent applications describe alternate score patterns and perimeter shapes for the constructible taster and other constructible utensils described herein. Those alternates may be combined with the basic taster and further modified as described herein in keeping with the present invention.
[0071]
[0072]
[0073]
[0074]
[0075] The perpendicular fold enables a pre-constructed length of constructible taster utensil shortened for packaging. Depending upon a location, the folded length may be shortened anywhere from 50% to 75% of the unfolded length.
[0076]
[0077] The constructible utensil of
[0078] The desired perimeter shape is cut, and a number of interior scores and cuts are formed within the blank. The cuts form a bullet-shaped functional portion that is hingedly fixed to the interior of the blank. A pair of lateral scores connecting ends of the cut to the exterior form hinges that allow the bullet-shaped functional portion to be displaced from the plane of the blank and rotated 180 degrees about the hinging lateral scores, so the functional portion now extends past the opening-shaped perimeter. Scores on the functional portion include a typical curved score pattern that are symmetric about a fold axis. That fold axis is aligned with a score on the interior portion of the blank, and thus allows the structure to be easily folded about the fold axis to produce a constructed utensil for use with the container. The constructible utensil thus saves material and folding costs as compared to the reference spoonlid system described herein.
[0079]
[0080]
[0081] Overwrap 110 is a stiff yet flexible paperboard material that has the properties required of a constructible utensil (thickness, stiffness, bendability, and the like) to be delivered by constructible utensil delivery system 100. Some implementations may not be paper stock but may be paper-like (e.g., other plant fiber besides tree fiber) or a calcium carbonate or an environmentally friendly suitable material that can be biodegradable and/or compostable, the materials as described in U.S. patent application Ser. No. 13/357,557 filed Jan. 24, 2021 (attorney docket ECOT 7006 US), the contents of which are expressly incorporated in their entirety by reference into the present patent application, as mentioned above.
[0082] Overwrap 110 is sized and shaped to preferably extend more than once around a container perimeter defined as the collection of all the sidewalls. By extending more than once around the container perimeter, overwrap 110 includes a free end 115 that overlaps a fixed end 120; the magnitude (length) of an overlapping portion 125 may be adjusted as described herein. Overwrap 110 is fixed to an outside exterior of the sidewall in many different ways. For example, fixed end 120 may be adhered to the outside exterior using an adhesive that is semi-tacky or permanent. A permanent adhesive ensures that overwrap 110 remains attached to container 105. A semi-tacky adhesive allows overwrap 110 to be removed after use.
[0083] Free end 115 is releasably secured (e.g., to a section of overwrap 110) using a semi-tacky releasable adhesive. The releasable adhesive or other securing mechanism secures free end 115 to overwrap 110 in a way that holds overwrap 110 in place during shipment and distribution yet is releasable to permit free end 115 to be unsealed and opened. Some implementations may further employ a sealed plastic bag or a second level overwrap that is shrink-wrapped or the like to container 105 which secures overwrap 110 in position.
[0084] A section of overwrap 110 covered by overlapping portion 125 includes a constructible utensil 130. Constructible utensil 130 is defined in or integrated with the section of overwrap 110 that is covered over by overlapping portion 125. For constructible utensil delivery system 100, constructible utensil 130 is completely covered by overlapping portion 125, which helps maintain it in a sanitary and clean condition to properly be used for serving foodstuff to be eaten.
[0085] Constructible utensil 130 has a length and width, the length greater than the width, and with the length equal to or less than a width of overwrap 110. Constructible utensil 130 is disposed vertically (the length extending between the bottom base and the top opening, and the width extending along the container perimeter). In this way, a reduced amount of overwrap 110 may be used (e.g., the length of overwrap 110 may be just sufficient to cover constructible utensil 130 before removal and the width of overwrap 110 is just greater than the length of constructible utensil 130, giving enough perimeter around the utensil to hold it into place).
[0086] Constructible utensil 130 is preferably defined in the section of overwrap 110 to be covered up by overlapping portion 125 using a series of perforations or other defined-tear propagation technique that allows a consumer to remove constructible utensil 130 from overwrap 110. That portion of overwrap 110 defining constructible utensil 130 cannot have permanent adhesive (but may use semi-tacky adhesive) holding overwrap 110 to the sidewall, or the consumer would not be able to remove constructible utensil 130. Permanent adhesive would have to be used outside the perimeter of constructible utensil 130. Note that it is preferred, but not required, that free edges of constructible utensil 130 match, or are otherwise preformed by shaping, fixed end 120. Thus, a handle and one lateral edge do not need to be torn or removed to separate constructible utensil 130 from overwrap 110. Other implementations may have a greater extent of perforations extending around a perimeter of constructible utensil 130, requiring more removal time and effort for a consumer, which can risk inadvertent damage to constructible utensil 130 as it is removed.
[0087] In operation, the consumer lifts free end 115 and peels overlapping portion 125 off of container 105 to reveal the underlying constructible utensil 130 defined in the revealed portion of overwrap 110. The consumer separates off constructible utensil 130 from overwrap 110 to hold an independent and discrete unconstructed constructible utensil 130 in hand. The consumer, if not having already done so, exposes the foodstuff-containing cavity of container 105 (e.g., removing the lid from the top opening) and constructs constructible utensil 130 to produce a utensil that the consumer then uses to consume the foodstuff from container 105.
[0088]
[0089] As illustrated, fixed end 320 is notched and preformed having portions of free lateral edges of constructible utensil 130 pre-cut and exposed from fixed end 320 and a limited perforation 325 added, which reduces the amount of tearing required to remove. This is consistent with an implementation of constructible utensil delivery system 100 described herein. In some implementations, fixed end 320 is square across its entire width and would require more time and effort to remove, possibly increasing risk of inadvertent damage to constructible utensil 130 during removal.
[0090] There are reasons why a manufacturer may prefer an implementation of first alternate constructible utensil delivery system 300 over constructible utensil delivery system 100. These reasons include a height of container 305 (or a width of overwrap 310 associated with container 305) being less than a desired length of constructible utensil 130, or the manufacturer preferring a horizontal disposition of constructible utensil 130 on container 305 (such to present advertising/marketing copy using overwrap 310 or constructible utensil 130 in a particular way). U.S. patent application Ser. No. 13/797,446 (attorney docket ECOT 7012 US, incorporated by reference into the present patent application as mentioned above), includes alternative shapes for constructible utensil 130, score patterns, and some discussion regarding adjustments of length of a constructible utensil 130 that could impact orientation of the utensil and dimensions of the overwrap.
[0091]
[0092] Except as expressly detailed, or where context clearly requires a different conclusion, components and elements of second alternate constructible utensil delivery system 500 conform to the corresponding components and elements of first alternate constructible utensil delivery system 300 described herein. Differences between second alternate constructible utensil delivery system 500 and first alternate constructible utensil delivery system 300 include a magnitude of overlapping portion 125 (i.e., it covers only a portion of constructible utensil 130, exposing a rear end of the handle portion while sealing and protecting an opposing food-contacting functional end), and fixed end 520 is illustrated completely square and therefore a perforation line 530 extends completely around the utensil perimeter (except in some cases for a very small area where the opposing food-contacting functional end aligns with fixed end 520).
[0093] As illustrated, fixed end 520 is NOT notched and preformed. More copy space is provided on overwrap 510 in this configuration (access when free end 515 is peeled away), which may be desirable in that overwrap 510 may be shorter than overwrap 310 for the same container and constructible utensil, as overlapping portion 125 is shorter in second alternate constructible utensil delivery system 500.
[0094] There are reasons why a manufacturer may prefer an implementation of second alternate constructible utensil delivery system 500 over constructible utensil delivery system 100 (similar to the reasons of selecting first alternate constructible utensil delivery system 300 over constructible utensil delivery system 100) or over first alternate constructible utensil delivery system 300. These reasons include reducing a manufacturing cost by reducing a length of overwrap 510 as compared to overwrap 310 to partially expose the horizontally disposed integrated constructible utensil 130, and/or improving consumer awareness of the availability of constructible utensil 130 prior to the consumer's purchase of a food container. A consumer unfamiliar with constructible utensil delivery system 100 or first alternate constructible utensil delivery system 300 may not realize that a constructible utensil is available for use and may therefore forego purchase. Second alternate constructible utensil delivery system 500 may address some of those concerns of the consumer without contaminating the food-contacting end. In this sense, partially exposing a vertically disposed constructible utensil is not preferred when the associated container includes foodstuff. However as other contexts exist for a container requiring a dispensing utensil for non-foodstuff contents, in some instances a partially exposed vertically disposed constructible utensil may be implemented without the same concerns about preservation of a sanitary condition for the non-food-contacting portion of constructible utensil 130 (which is the food-contacting portion for foodstuff containers).
[0095] In some embodiments, it will be desirable to provide some type of mechanism to maintain the lateral edges of the body (e.g., near the indicia) in a generally folded arrangement to preserve a desired minimum capacity/shape to the formed bowl (and to maintain those lateral edges extending upwards to be easily grasped to permit taster 130 to be picked up from a work surface, especially with the bowl shape retained). The material selection of the body and the depth and nature of the formation of the scores are one way to provide for a retaining force resisting unfolding when a folding force is removed. In other embodiments, some type of tacky adhesive or interconnecting tabs may be used to hold the lateral edges together and the body in the folded mode.
[0096]
[0097] The plurality of scores include a diameterial score 710 extending from a rear edge of the handle portion to a vertex 715. Diameterial score 710 extends along a diameter that divides body 705 into two generally symmetric halves. For other shapes, score 710 will not be a diameter but some other line with symmetry (e.g., a major or minor axis of an elliptical format).
[0098] The plurality of scores also include a pair of handle scores 720 that each extend from vertex 715 to an edge of body 705. Handle scores 720 form an angle less than ninety degrees with respect to diameterial score 710. The particular angle formed by these scores is related to the radius and/or length and width of body 705 as well as the placement of vertex 715 along the longitudinal axis. The length and width and placement of vertex 715 affect the defined volume of the constructed scoop made from constructible scoop 700. Note that the indicated score pattern is not necessarily reflective of which side of body 705 supports any given score. For example, different implementations may provide for any particular score to fold upwardly or downwardly (as seen from a top view such as
[0099] In addition to the plurality of scores, body 705 is preferably provided with one or more optional volume indicators and/or corresponding volumetric labels for a closed volume 805 (closed in this context means closed at the bottom and sides with a top opening). Volume indicators provide a user with a visual calibration (which may be approximate) of a volume of material disposed in the scoop of a constructed scoop as shown in
[0100] The handle portion also includes a pair of construction indicia 740 (e.g., the pair of “bend-to-touch dots”) and a colored score identifier 745. These indicia visually guide the user on how to manipulate body 705 to construct the scoop. The indicated action, in cooperation with the arrangement of the plurality of scores, initiates the constructing action to produce the final result. Note that “bend-to-touch” may in some instances be an indication to touch a “backside” of the dots together, such as when score 710 lifts relative to the lateral edges so the lateral edges move below score 710. Formation of the score pattern and particularly longitudinal score 710 to have a predisposition to folding in an appropriate and particular direction aids in any disambiguation as to which side of the dots are to be touched. In some cases, additional instructions may be useful and/or necessary to indicate to a user how to manipulate body 705. For example, the instruction text refers to a “green line” which references colored (i.e., “green”, though any distinguishing color or pattern may be used) score identifier 745. In this case, score 710, identified by colored score indicator 745, is pushed “up” to bring back sides of construction indicia 40 into contact.
[0101] In operation, body 705 is manipulated by bending, folding, and the like about the score pattern in order to touch the backsides of construction indicia 740. This action propagates bending, folding, and transformation forces along the score pattern so that vertex 715 “sinks” relative to the lateral edges to form closed volume 805. The scoop is completely constructed when the dots are touched; however, a partially constructed scoop may be useful in some contexts. The user grips the handle (formed from the handle portion) and operates the scoop to capture a desired quantity of material within closed volume 805.
[0102] In some embodiments, a tacky adhesive or other connection mechanism may be disposed on the backsides of the dots to maintain the scoop in the constructed mode. The connection mechanism may be temporary, allowing for deconstruction and flattening, or permanent to maintain the scoop in the constructed mode between uses and after the user releases the handle portion.
