According to common practice, the various features of the drawings discussed below are not necessarily drawn to scale. Dimensions of various features and elements in the drawings may be expanded or reduced to more clearly illustrate the embodiments of the disclosure.
Corresponding parts are designated by corresponding reference numbers throughout the drawings.
Containers according to the present disclosure can accommodate fluids, e.g., liquid or semi-liquid beverages that can include one or more solid components, of different sizes and compositions. For the purpose of illustration and not for the purpose of limiting the scope of the disclosure, the following detailed description describes a container for cool, cold, and/or at least partially frozen beverages, e.g., iced coffee, cold brew coffee, blended ice beverages (such as smoothies, slush beverages, milkshakes, etc.), iced tea, lemonade, and other flavored or unflavored beverages, to name a few. It will be understood that the containers described herein can hold different types of beverages and/or products containing one or more food items without departing from the disclosure.
In this specification, the terms “lower,” “bottom,” “upper,” and “top” indicate orientations determined in relation to fully erected and upright containers. As described herein, containers can be formed from blanks by overlapping multiple portions, panels, and/or end flaps. Such portions, panels, and/or end flaps may be designated herein in terms relative to one another, e.g., “first”, “second”, “third”, etc., in sequential or non-sequential reference, without departing from the disclosure.
In the illustrated embodiment, the sidewall construct 8 comprises an annular inner sidewall 19 (broadly, “inner wall”) and an outer sleeve 23 (broadly, “outer wall”) attached to the inner sidewall 19 such that the sidewall construct 8 can be referred to as a double wall structure. In one embodiment, one or both of the inner sidewall 19 and the sleeve 23 can be formed of paperboard, having one or more surface provided with, for example, a thermoplastic coating. Such paperboard can be provided with one or more desired surface features, for example, ribs or ridges, such as in fluted or corrugated paperboard. In one embodiment, the inner sidewall 19 can have a thickness of at least about 12 mil and the sleeve 23 can have a thickness of at least about 1 mil.
With additional reference to
In one embodiment, the insulating features of the container 5 are arranged such that a relatively low temperature, e.g., a temperature at or below about approximately 40° F. (or any suitable temperature for a cold beverage) of a cool, cold, and/or at least partially frozen fluid in the interior space 7 of the container 5 can be maintained, and such that the transfer of heat to the cool, cold, and/or at least partially frozen fluid in the interior space 7 from a surrounding environment E and/or a customer's hands can be substantially minimized, inhibited, and/or prevented. The insulating features of the container 5 additionally can maintain one or more surface conditions of the exterior surface of the sleeve 23 and/or exposed portions of the inner sidewall 19, for example, a surface temperature above the dew point of the surrounding environment such that condensation is minimized, inhibited, and/or prevented from forming on the container 5. In one embodiment, such condition can be maintained for up to and including about an hour or more. In this regard, a user can be provided with a more comfortable surface to grasp the container 5, e.g., such that the exterior surface of the outer sleeve 23 does not present or minimizes any cold temperature regions or zones that are uncomfortable to a customer's touch and/or a wet or slippery texture due to condensation. The container 5 can be provided with a different arrangement of insulating features without departing from the disclosure.
As shown, the bottom 13 of the container 5 includes a generally circular bottom panel 14 and an annular leg 15 downwardly-depending from the bottom panel 14 at a generally circular line of weakening 17. The bottom panel 14 has a diameter that generally corresponds to a horizontal distance between opposing sides of the inner sidewall 19. The inner sidewall 19 extends upwardly from the closed bottom 13 to define the interior space 7 of the container 5. The annular leg 15 is adhesively attached to a lower edge margin 20 of the inner sidewall 19 to secure the bottom 13 to the sidewall construct 8 and to form the bottom of the interior space 7 of the container 5. As shown, the lower edge margin 20 of the inner sidewall 19 extends along the outer surface of the annular leg 15, wraps under a lower edge thereof, and extends upwardly along the interior surface of the annular leg 15 toward the bottom panel 14. The lower edge margin 20 of the inner sidewall 19 can be an at least partially flexible portion of the inner sidewall 19 configured to engage the annular leg 15, and can include surface features to facilitate such engagement, for example, an adhesive treatment and/or frictionally-enhancing patterning. As described herein, the portion of the lower edge margin 20 of the inner sidewall 19 overlying the lower edge of the annular leg 15 will define an inner bottom edge or inner lower edge 18 of the inner sidewall 19. In one embodiment, the lower edge of the annular leg 15 can define the lower edge of the coupled inner sidewall 19 and the bottom 13.
The bottom 13 can be secured to the sidewall construct 8 in a different configuration without departing from the disclosure. For example, in one embodiment, the bottom 13 can be inserted into the interior space 7 formed by the sidewall construct 8 and coupled thereto, e.g., in the manner described above. In another embodiment, the bottom 13 and the annular leg 15 of the container 5 can be integrally formed with the inner sidewall 19 or can be otherwise attached to a portion of the inner sidewall 19 by other attachment means. In still another embodiment, the bottom 13 can be coupled to the inner sidewall 19 as described above, and the coupled inner sidewall 19/bottom 13 can be inserted into or otherwise coupled with the sleeve 23, e.g., via the spacers 29. In yet another embodiment, the sidewall construct 8 can be formed in a flat configuration, and then wrapped around and coupled to the bottom 13 in the manner described above.
As also shown, a top edge of the inner sidewall 19 is curved, curled, or otherwise flanged to define a top or upper rim 21 of the container 5 that circumscribes an opening 22 in communication with the interior space 7 of the container 5. The rim 21 and/or an upper portion of the container 5 can be configured to engage a lid or other top closure structure.
The illustrated configuration of the truncated conical shape of the container 5 can be achieved by forming the inner sidewall 19 from a flat blank by folding around a mandrel such that an overlapping seam is provided. The inner sidewall 19 (and the sleeve 23 disposed therearound), as shown, have a tapered configuration such that the inner sidewall 19 and the sleeve 23 extend at a constant angle α relative to a vertical centerline CL of the container 5.
Still referring to
As described herein, at least the interface between the sleeve 23 and the inner sidewall 19 of the container 5 forms insulating features of the container 5 that include a cavity 30 defined between the inner wall 19 and the outer sleeve 23. In one embodiment, the insulating features of the container 5 can also include one or more portions of the inner sidewall 19 and/or the sleeve 23. Alternative insulating features are further described in U.S. Provisional Patent Application No. 62/657,246, filed on Apr. 13, 2018, and U.S. Provisional Patent Application No. 62/674,834, filed on May 22, 2018, the entire contents of each of which are incorporated by reference herein.
As described further below, one or more of the bands B1, B2, B3, B4 can be a continuous band of adhesive arranged between the inner sidewall 19 and the outer sleeve 23 such that an at least partial seal is provided, e.g., to minimize, inhibit, and/or prevent the passage of fluid thereby. In one embodiment, one or more of the bands B1 through B4 can have one or more discontinuities therealong, for example, to provide ventilation paths among the bands B1, B2, B3, B4 and/or an external environment E. It will be understood that a different numbers of bands of spacers 29 can be present without departing from the disclosure. In one embodiment, surface features such as bands, ridges, protrusions, etc., can be provided in at least partial circumferential engagement around the inner sidewall 19, and can provide a surface or substrate upon which the bands of adhesive that form the spacers 29 can applied. Such surface features can provide an optimal surface for the adhesive interface between the inner sidewall 19 and the sleeve 23.
As shown in
Such insulating features can resist a temperature change of fluid in the container 5 by resisting the transfer of heat from the external environment E surrounding the container 5 to the cavity 30, and further to a fluid in the interior space 7 of the container 5. In one embodiment, heat from the surrounding environment E can be at least partially transferred to air or other fluid that is trapped or otherwise maintained in one or more of the pockets P1, P2, P3 between the respective bands B1, B2, B3, B4 of spacers 29. The pockets P1, P2, P3 thus provide an additional buffer, e.g., a heat sink, between the interior space 7 of the container 5 and the surrounding environment E, in addition to the inner sidewall 19 and the outer sleeve 23. In addition to maintaining a temperature of a fluid in the interior space 7 of the container 5, such insulation provided by the arrangement of the spacers 29 can also maintain a desired surface temperature of the sleeve 23 to facilitate comfortable grasping by a customer and/or maintain one or more desired surface conditions of the sleeve 23, e.g., to minimize, inhibit, and/or prevent condensation as described above. Further still, the arrangement of the bands B1, B2, B3, B4 of spacers 29 can impart desired structural properties to the container 5, for example, by providing a desired pattern of rigidity such that an optimal pattern of flexion is provided to the container 5 during use. For example, upon grasping of the sidewall construct 8 by a customer, portions of the sleeve 23/inner sidewall 19 can bend or flex inwardly into one or more of the pockets P1, P2, P3 to provide a textured or irregular surface configuration to enhance the customer's grip on the container 5.
Referring additionally to
As shown, the container 105 includes the sidewall construct 108, which includes the inner sidewall 19 and an outer sleeve 123. Insulating features are disposed between the inner sidewall 19 and the outer sleeve 123 of the container 105 as described above with respect to the container 5. For example, and as shown, bands B1, B2, B3, B4 of spacers 29 can be disposed between the inner sidewall 19 and the outer sleeve 23, and define the respective pockets P1, P2, P3 therebetween.
The outer sleeve 23 extends downwardly past the lower edge 18 of the inner sidewall 19 to form an annular base 125 of the container 105 such that a lower portion of the outer sleeve 23 defines an interior annular recess 126 between the lower edge 127 of the annular base 125/container 105 and a bottom panel 114.
A lower edge margin 128 of the sleeve 23, as shown, is interiorly folded into the annular recess 125 into face-to-face contact with a lower portion of the outer sleeve 123/annular base 125 to define the lower edge 127 and to provide a two-ply structure at a bottom portion of the annular base 125 upon which the container 105 can rest in an upright orientation.
As also shown, the closed bottom 113, including the bottom panel 114 and an annular leg 115 foldably connected thereto at a line of weakening 117, are positioned a vertical distance above the lower edge 127 of the container 105, and an annular discontinuity or annular gap G is defined between the lower edge 18 of the inner sidewall 19 and an upper edge U of the lower edge margin 128 of the sleeve 23. In one embodiment, the annular gap G can provide a vent for one or more portions of the cavity 30.
In one embodiment, the inner sidewall 19 and the sleeve 123, with insulating features therebetween, can be separately formed from the closed bottom 113, and so that the bottom 113 can be coupled to the sidewall construct 8 to form the container 105. In this regard, the sidewall 108 can be produced as a structure that receives the bottom 113 so that the bottom 113 can be selectively coupled at different locations of the sidewall 8 to provide an interior space of the container 105 with a different selected interior volume. Such features are described in U.S. Provisional Patent Application No. 62/674,834, filed on May 22, 2018, the entire contents of which are incorporated by reference herein
