Many food products are stored and shipped in lightweight plastic containers. Typically, a plastic container is constructed to facilitate automated packaging of the food products. The containers are typically designed to be shipped from a manufacturer in a stacked arrangement.
Because the container is intended to be used for shipping and display after packaging, it is desirable that the container, in some situations, be placed in a vertical or angled standing position. This is because the top surface of the container has a larger area than a side surface, and thus any branding materials applied to the container will have a larger display area. Some containers are designed to be placed in shelf display stand that is cooperatively shaped to receive a container and maintain the container in a vertically biased position. Other containers have base potions defining shaped volumes that taper to a reduced cross-sectional area near the top of the container when the container is placed in the vertical position so that a center of gravity of the container is position to bias the container in the vertical position. Still other containers have specially designed support structures that are separate from peripheral flanges and that support the container in a standing position.
This specification describes technologies relating a container, such as a food container, that may be vertically biased in a standing position when filled to a capacity of product. As used in this description, the term “vertically biased” means that a container is positioned such that the bottom surface of the container is displayed from a flat surface on which the container is rested by at least an acute angle and tends to remain in this position. As such, a top surface of a lid of the container is prominently displayed.
In general, one innovative aspect of the subject matter described in this specification can be embodied in a container apparatus that includes: a base section, comprising a base surface defining a base plane, base sidewalls extending upward from the base surface to define a base container portion having an upper base periphery, wherein one of the base sidewalls is a front base sidewall, and the front base sidewall extends upward from the base surface to define a base corner on the exterior of the base section, and a base flange projecting outward relative to at least the front base sidewall; a lid section, comprising a lid surface defining a lid plane, lid sidewalls extending downward from the lid surface to define a lid container portion having a downward lid periphery, wherein one of the lid sidewalls is a front lid sidewall, and a lid flange projecting outward relative to at least the front lid sidewall. When in a closed position, the lid flange and the base flange are in juxtaposition and at least one of an outer edge of the base flange or an outer edge of the lid flange defines a flange support surface; the lid surface is spaced above upper base periphery when in the closed position to define a lid volume from the upper base periphery to the lid surface, and the base section defines a base volume from the upper base periphery to the base surface; and the flange support surface extends outwardly a first distance such that when the combined lid volume and the base volume is loaded with a rated capacity of product and the container apparatus is placed in a standing position on a flat surface using the flange support surface and the base corner as respective support elements, a resulting center of gravity of the container apparatus generates a moment about an axis of the base corner that biases the container apparatus in the standing position.
Particular embodiments of the subject matter described in this specification can be implemented so as to realize one or more of the following advantages. The container, by having the lid volume in addition to the base volume, has a center of gravity that causes the container to remain in the vertically biased position. This eliminates the need for a specially designed receiving stand, which reduces production costs and does not impede salability of the container to food manufactures. Moreover, the lid volume eliminates the need for the base volume to taper asymmetrically from the front side surface nearest a flat surface on which the container rest to a back side surface that is opposite the front side surface. This allows for a more efficient volume usage for any given set of outer cubic dimensions, i.e., a cubic region in which the container fits, that can receive the container. Finally, because the container uses one or both of an outer edge of a lid flange and base flange in combination with a front bottom corner of the container as support surfaces, the container need not have other attachments or integrally formed features to support the container in the vertical position. This reduces production costs and facilitates stacking of the container for shipment and for use in food packing processing equipment.

With reference to
These features and additional features are describe in more detail below.
Referring generally to Figures, the container apparatus 100 includes a based section 200 and a lid section 300. The base section and lid section may be flexibly connected to each other, such as by a living hinge 402. Other hinge connections may also be used.
The base section 200 includes a base surface 202 defining a base plane 204, and base sidewalls 210, 212, 214 and 216 extending upward from the base surface 202 to define a base container portion having an upper base periphery 218. The volume within the base sidewalls 210, 212, 214 and 216 and base surface 204 to the upper base periphery 218 is referred to as the base volume. The base sidewall 210 is a front base sidewall 210, and the front base sidewall 210 extends upward from the base surface 202 to define a base corner 220 on the exterior of the base section 200. It is on this base corner 220 that the container apparatus 100 rests when in the vertical position. The base section also includes a base flange 230 projecting outward relative to the front base sidewall 210.
The lid section 300 has a lid surface 302 defining a lid plane 304, and lid sidewalls 310, 312, 314 and 316 extending downward from the lid surface 302 to define a lid container portion having a downward lid periphery 318. The volume within the lid sidewalls 310, 312, 314 and 316 and lid surface 302 to the downward lid periphery 318 is referred to as the lid volume. The lid sidewall 310 is a front lid sidewall 310, and a lid flange 330 projects outward relative to front lid sidewall 310.
As illustrated in
As shown in
The distances L, as reference in
In the example implementation shown, the base flange 230 and lid flange 330 project outward relative to the front base sidewall 210 and at a position this is below the upper base periphery 218 by a distance L8. The distance L7, which separates the downward lip periphery 318 from the lid surface 300, when combined with the inner width L15 and inner depth L16 of the downward lid periphery 318, substantially defines the lid volume. Likewise, the distance L9, which separates the upper base periphery 218 from the base surface 202, when combined with the inner width L13 and inner depth L17 of the upper base periphery 218, substantially defines the lid volume.
In the example implementation shown in
The resting angel B can be selected, in part, on the position of the center of gravity 410. As shown in
In some implementations, the lid plane 304 is parallel to the base plane 204, and thus the angel C of the lid plane relative to the surface 102 is the same as B. However, in some implementations, the lid portion 300 can be shaped so the lid surface 302 is not parallel to the base surface 202, such that the angle of the lid plane 304 may vary, as indicated by alternate lid planes 304′ and 304″. Note that the lid plane 304′ will cause the center of gravity 410 to move toward the lid portion 300, while the lid plane 304″ will cause the center of gravity 410 to move toward the base portion.
When the container apparatus 100 is in the closed position with the lid plane 304′, the second angle C is greater than the first angle B. Conversely, the container apparatus 100 is in the closed position with the lid plane 304″, the second angle C is less than the first angle B.
As described above, the base flange 230 is below the upper base periphery 218, and the lid flange 330 is below the downward lid periphery 318. These vertical dispositions are, in some implementations, achieved by use of displacement flanges. For example, as shown in
In some implementations, the lid displacement flange 334 and the base displacement flange 234 include respective integrally formed and cooperatively placed locking components 336 and 236 so that the lid section 300 and the base section 200 interlock when the container apparatus 100 is in the closed position. In the example of
The locking components 336 and 236, combined with the lid volume, also facilitate stacking of multiple containers, as shown in
Other types of locking components can also be used and in other locations. For example, in
The container 100 may be formed out of a variety of appropriate materials. In some implementations, the container 100 is made of polyethylene terephthalate (PET) thermoplastic polymer resin. The container 100 may be clear, or may be opaque. Furthermore, other plastic materials may also be used to form the container 100. Alternatively, a paper product or extruded polystyrene foam maybe used to form the container 100.
