Fruit container
A food container that includes upper and lower trays (12), each of sheet plastic and having a plurality of food-holding recesses (30) for holding pieces of fruit, with the two trays preferably being identical. The two trays have complementary latches (80, 90) to latch to each other when the container is closed, the individual trays being stackable in a tight stack for storage and transport, and the closed containers being stackable. The latches are in the form of projection latches (80), and in the form of socket latches (90) that receive projection latches. The arrangement of projection and socket latches (and of aligners 70, 72) forms mirror image arrangements on opposite sides of a mid plane (102), so the upper tray is identical to the lower one, and the upper tray can be latched to the lower one by turning the upper tray 180° about an axis (100) lying on the mid plane. The trays each form recesses (30) and barriers (46) between recesses, and the intersection of each group at least three barriers forms a platform (50) that supports one of the latches. Positioners (111-114) that allow container stacking, include socket positioners (113-114) that each includes a downward projection (140) that projects down from the bottom of a recess and that forms an upwardly opening passage (142) with a support wall (143) that can support a piece of fruit that lies in a recess.
Food containers can be constructed with upper and lower container elements, or trays, that are each constructed of a sheet of plastic (preferably transparent) that has been formed as by vacuum forming. In many cases, the upper and lower trays are latched together at their peripheries. Some containers are large and hold heavy food spherical items such as pears, avocados and apples and other pieces of fruit. For such containers, it is desirable to align the upper and lower trays at many spots spaced from their peripheries as well as to latch them together at their peripheries. When such containers containing fruit pieces are stacked, it is desirable that they rest on one another at locations in addition to their peripheries. Also, positioners that keep the vertical stack of fruit-filled containers aligned, should be formed to provide wide support for the bottom of a piece of fruit.
SUMMARY OF THE INVENTIONIn accordance with one embodiment of the invention, a container is provided of the type where the upper and lower trays are produced by formed sheet plastic, that is suitable for holding heavy food, and especially pieces of largely spherical fruit. The trays have aligners, some of which are also latches in the form of socket aligners and projection aligners that enable the upper and lower trays to latch together. The upper and lower trays can be made identical by an arrangement of projection and socket aligners that form patterns that are mirror images of each other on opposite sides of a mid plane of each tray. In that way, when one tray is turned 180° about a horizontal axis lying in the mid plane, the tray is converted from a lower tray to an upper tray, and its projection and socket aligners mate with those of the lower tray.
In a container for holding pieces of heavy and largely spherical fruit such as apples, pears, and avocados, the trays each forms part-spherical recesses that each holds one piece of fruit. When a plurality of such containers are stacked on one another, it is desirable to provide positioners that prevent any container from moving out of alignment with the other containers in the stack, and to provide good support of each container on the one below. Applicant provides locators on the bottom of each lower tray and on the top of each upper tray. Each locator in a lower tray is formed by downwardly deforming a location at the bottom of a recess to form a projection or socket locator. Each socket locator includes a downwardly extending large diameter part whose middle forms an upwardly projecting passage with a top wall that can support a piece of fruit. The middle of the bottom of the bottom tray and the middle of the top of the top tray, form flat spots that better support stacked containers on one another and that provide an area for holding a label.
The novel features of the invention are set forth with particularity in the appended claims. The invention will be best understood from the following description when read in conjunction with the accompanying drawings.
DESCRIPTION OF THE DRAWINGS
The tray 12 of
As shown in
The tray shown in
The trays can be stacked in a compact stack for shipment to stores and for storage. When the trays (not yet assembled into a container) are stacked with their fruit-holding recesses facing upward, each projection aligner such as 112 fits into the blind hole of a socket aligner of the tray below or above it. Also each socket aligner receives the projection formed by the socket aligner of the tray below or above it. The projection and socket latches are similarly stacked in one another.
When a group of closed containers that hold fruit are stacked on one another, the positioners align the four sides of the container, and the flat spots 44 at the middle of the trays lie against one another. The flat spots lie on the stacking planes where each container lies against another container. The flat spots not only provide large area contact, but provide a large area where a label can be pasted on one of the trays of a container.
Applicant has designed and tested containers of the type shown in
While applicant prefers to use two identical trays of the type shown in
The trays are designed to be manufactured at a specialized facility and shipped to supermarket stores or to specialized packagers of fruit. Clerks at the stores or at the packagers, take one tray (or one container of the type of
Thus, the invention provides a food container, and especially one with recesses for holding pieces of primarily spherical fruit such as pears, avocados and apples, without forming pressure spots on the fruit, and which is formed by deformed sheets of plastic. The trays are constructed to enable secure latching together of two trays of the container, and to assure that a stack of containers that hold food will maintain the alignment of the stack and provide good support by each container, of the containers on top of it. The upper and lower trays of each container can be made identical by constructing each tray so it has mirror symmetry about a longitudinal axis (or about a lateral axis). Each tray forms aligners at the tops of platforms, with some aligners being latches, to hold two trays together as a container. Each container has positioners that assure that a stack of trays maintain their vertical alignment, with each positioner formed at the bottom of a fruit-holding recess without forming a recess wall that will concentrate pressure on a piece of fruit. The aligners and positioners can be of any of a variety of shapes. The two trays of a container can be different, and can be pivotally connected by a living hinge.
Although particular embodiments of the invention have been described and illustrated herein, it is recognized that modifications and variations may readily occur to those skilled in the art, and consequently, it is intended that the claims be interpreted to cover such modifications and equivalents.
