This invention related to the field of packaging, and more particularly, packaging having lids attached to a container body.
Many types of products, such as granular or powdered products (e.g., infant formula, flour, coffee, sugar, etc.), are packaged in containers having lids. The containers may come in a variety of configuration. In some instances, the lids of the containers can rotate out of position (orientation) when assembled onto a container having a round opening. Lid orientation is often desired to align a lid feature and/or lid messaging with a certain position on the container.
According to one aspect of the present disclosure, a container is provided having a main body including one or more sidewalls having an interior surface and an exterior surface and defining an interior compartment, the one or more sidewalls having an upper portion defining a circular opening to the interior compartment and an annular flange extending from the exterior surface and a lid-collar assembly comprising a lid attached to a collar affixed to the main body, the collar having an inner side surface positioned radially outward of the annular flange and a plurality of longitudinally extending ribs spaced apart on the inner side surface, wherein the plurality of ribs engage the annular flange to resist rotation of the lid-collar assembly relative to the main body
In another aspect of the present disclosure, a method of securing a collar-lid assembly onto a container body is provided where the collar-lid assembly includes an inner side surface and the container body includes one or more sidewalls having an interior surface and an exterior surface and defining an interior compartment, the one or more sidewalls having an upper portion defining a circular opening to the interior compartment and an annular flange extending from the exterior surface. The method includes pressing the collar-lid assembly onto the container body such that the inner side surface is radially outward of the exterior surface, positioning one or more retaining elements located on the inner side surface beneath the annular flange to resist axial separation of the collar-lid assembly from the container body, and creating a friction fit between one or more anti-rotation elements on the inner side surface and the annular flange to resist rotation of the collar-lid assembly relative to the container body.
Further features and advantages of the invention will become apparent from the following detailed description made with reference to the accompanying drawings.
Features and advantages of the general inventive concepts will become apparent from the following detailed description made with reference to the accompanying drawings.
This Detailed Description merely describes exemplary containers and methods in accordance with the general inventive concepts and is not intended to limit the scope of the invention or the claims in any way. Indeed, the invention as described by the claims is broader than and unlimited by the exemplary containers and methods set forth herein, and the terms used in the claims have their full ordinary meaning.
The body 104 may be configured in a variety of ways. Although the body 104 of the exemplary container 100 is described and illustrated to be substantially cylindrical, the present invention is susceptible for use with all shapes and sizes of containers including cuboid, obloid, rectilinear, and other shapes, which may have a circular, or near circular opening. Furthermore, each of the optional and preferred examples of the invention contemplate interchangeability with all of the various features, components, modifications, and variations illustrated throughout the written description and pictorial illustrations.
In the illustrated container, the body 104 is substantially cylindrical about a longitudinal axis A with a cylindrical side wall 106 having an inner surface 120 (
The annular flange 128 may be configured in a variety of ways, including different shapes and sizes of the flange 128. In the illustrated container, the annular flange 128 has a height H1, extends a maximum distance X1 from the outer surface 122, and has a curved exterior surface 130. The body 104 may be constructed from any suitable material. In one embodiment, the container 100 is constructed from a polymeric material, such as, for example, polypropylene high-density polyethylene (HDPE), low-density polyethylene (LDPE), polyethylene terephthalate (PET), and/or polycarbonate.
The collar 112 and the lid 116 may be configured in a variety of ways. The collar 112 and the lid 116 may be formed as an integral collar-lid assembly 118 or the collar 112 and the lid 116 may be separate components that may attach together in any suitable manner. The lid 116 is moveable relative to the collar 112 between an closed position in which the lid 116 covers the opening 110 to the interior compartment 108 or an open position in which the opening 110 is not covered by the lid 116 and the contents of the container 100 are accessible via the opening 110.
The lid 116 may be attachable to the collar 112 in a variety of ways. Any configuration that allows the lid 116 to move between the open and closed positions may be used. Non-limiting examples may include (i) the lid 116 includes threads that allow the lid 116 to screw onto corresponding threads on the collar 112, (ii) the lid 116, and/or collar 112, have a detent mechanism that allows the lid 116 and collar to snap together, or (iii) the lid 116 is joined to the collar 112 with a hinge that allows the lid 116 to pivot relative to the collar 112.
Referring to
In the illustrated container, the lid 116 is generally cylindrical with a cylindrical side wall 140 having an inner surface 142 and an outer surface 144 opposite of and generally parallel to the inner surface 142. The lid 116 has an open lower end 146 having a lower circumferential edge 148 and a closed upper end 150 having a top wall 152 with an inner surface 154. In the illustrated container, the lid 116 includes a scoop holder 156 for holding and storing a scoop 158 onto the inner surface 154 of the top wall 152. The container 100 may also include a removable, substantially moisture-impervious, oxygen-impervious seal (not shown) between the lid 116 and the interior compartment 108.
In the illustrated container, the collar 112 is generally ring-shaped with a cylindrical side wall 160 having a height H2, an inner surface 162, and an outer surface 164 opposed to and generally parallel to the inner surface 162. The inner surface 162 has a diameter D2 configured to fit over the upper portion 114 of the body 104. The collar 112 has an open lower end 166 having a lower circumferential edge 168 and an open upper end 170 having an upper circumferential edge 172.

Referring to
The inner wall 194 includes a lower circumferential edge 196 and is connected to the inner surface 162 of the upper portion 190 of the collar 112 by a plurality of radially-extending bridges 198. The bridges 198 may be configured in a variety of ways, including the number, the size, and the location of the bridges 198. In the illustrated container, the inner wall 194 is connected to the inner surface by eighteen (18) bridges 198 spaced around the outer circumference of the inner wall 194. In some configurations of the container, the bridges 198 are equally spaced around the outer circumference of the inner wall 194. In other configurations, however, the bridges 198 may not be equally spaced. Each of the plurality of bridges has a thickness similar to the thickness of the inner wall 194, such as for example 75% to 125% the thickness of the inner wall 194. In other configurations of the container, however, the number of bridges 198 may be less than or more than eighteen, the bridges may not be equally spaced, and/or the thickness of the bridges may be less than 75% or greater than 125% the thickness of the inner wall 194.
The lower portion 192 of the inner surface 162 may be characterized as the portion of the inner surface below the lower circumferential edge 196 of the inner wall 194. The lower portion 192 may include one or more retaining elements 200 configured to resist removal of the collar 112 from the body 104, i.e., resist axial separation of the collar 112 from the body 104. The one or more retaining elements 200 may be configured in a variety of ways. For example, the size, the shape, the location, the orientation, and the number of retaining elements 200 may vary in different configurations of the container. Any configuration capable of resisting axial separation of the collar 112 from the body 104 may be used.
In the illustrated container, each of the one or more retaining elements 200 is configured as a ridge extending radially inward from the lower portion 192. Each ridge-shaped retaining element 200 has a convex inner edge 202 that extends radially inward a maximum distance X2 (
In the illustrated container, the collar 112 includes six pairs of retaining elements 200 for a total of twelve retaining elements 200 on the inner surface 162. Each pair of retaining elements 200 includes two retaining elements circumferentially side-by-side. Each pair of retaining elements 200 is circumferentially spaced apart from the next pair. For example, one pair of retaining elements 200 may circumferentially extend about 20 degrees along the inner surface 162 followed by about 10 degrees of inner surface 162 with no retaining element, with the pattern repeating around the entire circumference of the inner surface 162.
The lower portion 192 may include one or more anti-rotation elements 210 configured to resist rotation of the collar 112 relative to the body 104, i.e., resist rotation about longitudinal axis A. The one or more anti-rotation elements 210 may be configured in a variety of ways. For example, the size, the shape, the location, the orientation, and the number of anti-rotation elements 210 may be vary in different configurations of the container. Any configuration capable of resisting rotation about longitudinal axis A of the collar 112 relative to the body 104 may be used.
In the illustrated container, each of the anti-rotation elements 210 is formed as an elongated rib extending longitudinally along the inner surface 162 of the lower portion 192. In the illustrated container, each of the rib-shaped anti-rotation elements 210 is axially aligned with and coextensive with a bridge 198. In other configurations of the container, however, one or more of the rib-shaped anti-rotation elements 210 may not be axially aligned and coextensive with a bridge 198.
Each anti-rotation element 210 has a distal end 212 connected to a proximal end 214 opposite the distal end 212 by an inner face 216 and a pair of opposite lateral faces 217, such that the anti-rotation element 210 is generally rectangular in cross-section. In other configurations of the container, however, the anti-rotation element 210 have other than rectangular in cross-section, such as for example, semicircular.
In the illustrated container, the distal end 212 has a convex curved surface and the inner face 216 is planar. In other configurations of the container, however, the inner face 216 may be other than planar, such as curved for example and the distal end 212 may be configure other than convex, such as planar for example. Further, in the illustrated container, the proximal end 214 is connected to a bridge 198. In other configurations of the container, however, the proximal end 214 may be spaced apart from a bridge 198.
Each anti-rotation element 210 has a length L, a thickness T, and a width W (
In one exemplary configuration of the container 100, the length L is in the range of 3.302 inches (0.130 inches) to 4.318 mm (0.170 inches), or 3.81 mm (0.150 inches). In other configurations, however, the length L may be grater than 4.318 mm or less than 3.302 mm. In one exemplary configuration of the container 100, the thickness T is in the range of 0.435 mm (0.017 inches) to 0.835 mm (0.033 inches), or 0.535 mm (0.021 inches) to 0.735 mm (0.029 inches), or 0.635 mm (0.025 inches). In other embodiments, however, the thickness T may be greater than 0.835 mm or less than 0.435 mm. In one exemplary configuration of the container 100, width W is in the range of 0.435 mm (0.017 inches) to 0.835 mm (0.033 inches), or 0.535 mm (0.021 inches) to 0.735 mm (0.029 inches), or 0.635 mm (0.025 inches). In other embodiments, however, the width W may be greater than 0.835 mm or less than 0.435 mm. In one exemplary configuration of the container 100, the width W is equal to the thickness T. In other configurations, however, the width W is not equal to the thickness T. In one exemplary configuration of the container 100, one or more anti-rotation elements have a length L such that the distal end 212 terminates at the centerline of the convex inner edge 202 of the retaining elements 200. Thus, in one exemplary configuration of the container 100, the length L is equal to the distance X3. In other embodiments, however, the length L may be greater or less than the distance X3.
In the illustrated container, each of the anti-rotation elements 210 is circumferentially offset from each of the retaining elements 200. The arrangement of anti-rotation elements 210 relative to retaining elements 200 may vary in different configurations of the container. Any suitable arrangement may be used. For example, the illustrated container includes eight (8) anti-rotation elements 210 spaced circumferentially around of the inner surface 162 and six pairs of retaining elements 200. Referring to
The collar 112 and the lid 116 may be constructed from any suitable material. In one configuration of the container, the collar 112 and the lid 116 are constructed from a polymeric material, such as, for example, polypropylene, high-density polyethylene (HDPE), low-density polyethylene (LDPE), polyethylene terephthalate (PET), and/or polycarbonate. In an exemplary configuration of the container, the collar 112 and the lid 116 are constructed from the same material as the body 104. In other configurations of the container, however, the collar 112 and the lid 116 are constructed from one or more different materials than the body 104. In addition, the anti-rotation elements 210 may be configured from any suitable material, including a polymeric material, such as, for example, polypropylene, high-density polyethylene (HDPE), low-density polyethylene (LDPE), polyethylene terephthalate (PET), and/or polycarbonate that is the same as the collar 112 or different than the collar 112.
The collar 112 may attach to the container body 104 in a variety of ways including clips, friction-fit configurations, snap-on arrangements and other equally desirable and optional components and methods. In the illustrated container, the collar 112 is configured to be attached and assembled to the container 100 by pressing the collar 112 axially downward onto the upper portion 114 of the body 104. When the collar 112 is pressed downward onto the upper portion 114, the retaining elements 200 engage the annular flange 128 resulting in the sidewall 106 of the body 104 deflecting radially inward and/or the cylindrical side wall 160 of the collar 112 deflecting radially outward to allow the retaining elements 200 to move past the annular flange 128. Alternatively, or in conjunction with one or both of the side walls 106, 160 deflecting, one or both of the retaining elements 200 and annular flange 128 may elastically deform to allow the retaining elements 200 to pass the annular flange 128.
Once the retaining elements 200 are moved downward past the annular flange 128, the sidewall 106 of the body 104 and/or side wall 160 of the collar 112 return to their pre-deflected position, or toward their pre-deflected position, such that each of the retaining elements 200 snap under the annular flange 128 and are positioned below the annular flange 128. Alternatively, or in conjunction with one or both of the side walls 106, 160 returning to, or toward, their pre-deflected position, one or both of the retaining elements 200 and annular flange 128 may return to their pre-deformed configuration, or toward their pre-deformed configuration. When the retaining elements 200 are positioned below the annular flange 128, axial separation of the collar 112 from the body 104 is resisted because the annular flange 128 interferes with the retaining elements 200 moving in an axially upward direction. In this way, the annular flange 128 and the retaining elements 200 act as a detent mechanism that keeps the collar 112 in position relative to the body 104.
As the collar 112 is pressed axially downward onto the upper portion 114 of the body 104, the lower circumferential edge 196 of the inner wall 194 and/or the bridges 198 may act as a stop to prevent further axially movement downward of the collar 112 relative to the body 104. In particular, the lower circumferential edge 196 and/or the bridges 198 may engage the upper circumferential edge 126 of the upper portion 114 of the body 104 preventing further downward axially movement of the collar 112 relative to the body 104.
Further, as shown in
In one exemplary configuration of the container, one or more of the anti-rotation elements 210 will plastically deform against the annular flange 128. For example, as the collar 112 is pressed axially downward onto the upper portion 114 of the body 104, one or more of the anti-rotation elements 210 may plastically deform 220 (e.g., smear) as the anti-rotation elements 210 engage the annular flange 128. Any number of the one or more anti-rotation elements 210 may plastically deform when the engaging the annular flange 128, including all of the anti-rotation elements 210 or less than all of the anti-rotation elements. In other configurations of the container, however, the anti-rotation elements 210 may not plastically deform against the annular flange 128. For example, the sidewall 106 of the body 104 may deflect inward and/or the cylindrical side wall 160 of the collar 112 may deflect outward such that a friction fit is still formed between the anti-rotation elements 210 and the annual flange 128 to resist rotation of the collar 112 relative to the body 104, but the fit does not result in the anti-rotation elements 210 plastically deforming.
As shown in
Due to the configuration of the collar-body interface and the configuration and orientation of the anti-rotation elements 210, the anti-rotation elements 210 are self-adjusting. For example, tolerance variation in the diameter D1 of the outer surface 122 of the upper portion 114 of the body 104, the maximum distance X1 the annular flange 128 extends from the outer surface 122, the diameter D2 of the inner surface 162 of the collar 112, and the thickness T of the anti-rotation elements 210 can impact the fit of the collar 112 onto the upper portion 114 of the body 104. The anti-rotation elements 210 can compensate for some tolerance variation due to the degree in which anti-rotation elements 210 plastically deform and the orientation of the anti-rotation elements around the circumference of the inner surface 162 of the collar 112, which provides a centering function. Thus, the amount of deformation of the anti-rotation elements 210 allows the collar 112 to fit cans with varying annular flange diameters (i.e., manufacturing tolerance).
