Four embodiments of a tray are disclosed for transporting and storing milk containers and for nesting the trays for their return trip to their origin.

The present arrangement includes a plurality of substantially identical thermoformed shelves, each constructed with a surface and four legs. Any two of the plurality of shelves are such that the four legs of any one shelf are constructed to mate with the four legs of any other shelf. Any two of the plurality of shelves are such that the surface of one shelf mates against the surface of another of any one of the shelves. The arrangement is constructed with at least two of the plurality of shelves are arranged leg to leg and at least two of the plurality of shelves are arranged surface to surface.

A method for fabricating a lid or a base of a container, the lid or base comprising a web and an outer boundary, the method comprising injecting a plastic material through at least a first number of first cavities having a first thickness and through at least a second number of second cavities having a second thickness, the first cavities leading to the outer boundary of the lid or base, the first thickness being larger than the second thickness; and selectively cooling the first cavities and the second cavities.

A container storage system comprises structural members with particular hole patterns. In particular, a series of holes placed on an exterior face of a core module horizontally along its centerline relative to its height (core module height/2) are also placed on any additional module the same distance (core module height/2) from its mating face (to the core module) to facilitate connection with hinges and connectors by the use of inserting removable hardware through the holes. This structural arrangement allows for a combination of modules to be disassembled and reconfigured as a user's storage needs and/or conditions change over time. The modular storage system is scalable to any size and may be made from any material strong enough to support its own weight and the weight of its contents.

A separate and stackable serving dish or tray is disclosed configured to be releasably connected to an identical separate serving dish or tray to form a box for holding an item of food. Each serving dish or tray incudes a base wall and a sidewall upstanding and flaring outward from the base wall. The sidewall includes a male hermaphroditic connector located at a first portion of its upper edge and a female hermaphroditic connector at another portion of its upper edge. The male hermaphroditic connector of one serving dish or tray is configured to be releasably connected to the female hermaphroditic connector of an identical serving tray. Each serving dish or tray may also include auxiliary connectors to provide additional securement of the two serving dishes or trays to each other. Moreover, the serving trays may include one or more vents.

A container includes trays having a substantially identical profile. For each tray, the tray includes a rim that includes a proximal segment, a bead segment, and at least one vent channel defined in the proximal segment, the bead segment has an upwardly-extending member and a downwardly-extending member, the upwardly-extending member defines a first cavity, and the downwardly-extending member defines a second cavity. When the trays are engaged to close the container, the upwardly-extending member of the first tray is received in the second cavity of the second tray, the upwardly-extending member of the second tray is received in the second cavity of the first tray, the first and second trays define an interior volume of the container, the proximal segments of the rims of the first and second trays are in face-to-face contact to substantially seal the interior volume, and each vent channel is in communication with the interior volume.

The invention relates to a system of stackable open-top containers. The system comprises male and female containers that can be alternately stacked, either in upright or inverted position. When the system contains containers that are stacked in inverted position on top of upright container, substantial space saving is obtained by the system. The invention also provides male and female containers that are useful in the system of containers.

The protecting package for a flexible pouch specially designed to contain a biopharmaceutical fluid, includes two frames which respectively form a lower frame and an upper frame and which have a peripheral area, respectively to a main plane of the frames, each frame has an opening on a central area, the two frames are fixed to each other such that they are able to respectively surround two plates which sandwich the flexible pouch.

A hair color retouch kit, components of the kit, and methods of use and doing business. The kit can include one or more mixing containers. In one embodiment, a mixing container provides a colorant compartment for sealingly or separately containing a custom hair coloring formulation and peroxide compartment for sealingly or separately containing peroxide. The mixing container(s) can be used by a professional hair colorist to provide a hair coloring client with custom hair coloring formulation and peroxide that can be mixed and applied by or for the client to hair regrowth that occurs after a hair coloring session with the professional. The kit can provide other components as desired, such as a mixing spatula, an applicator brush, and instructions for example. The kit can be packaged in attractive and efficient packaging, include indicia identifying the source of the kit, and be customized to promote the colorist, salon, or other entity.
