FEDERALLY SPONSORED RESEARCH OR DEVELOPMENTN/A
FIELD OF THE INVENTIONThe present invention generally relates to a molded plastic tray for supporting a plurality of milk bottles, and more particularly to a tray that can be combined with a sleeve to allow for stacking a plurality of layers of trays supporting such bottles.
BACKGROUND OF THE INVENTIONCurrently, metal carts—referred to as “bossy” carts—are typically used to transport and present milk to customers via a series of rigidly connected racks on each cart. The milk bottles on each rack are not used to provide any support for any additional racks above the bottles.
The present invention provides an improved tray system that uses the bottles on the tray in conjunction with a sleeve to support layers of bottles (on additional trays) above the tray at issue.
SUMMARY OF THE INVENTIONThe present invention provides a tray, sometimes referred to as a milk tray, to transport a plurality of bottles, such as gallon sized milk bottles or containers (the bottles can hold other fluids, such as distilled water or apple cider for example). The milk tray can utilize the bottles supported on the tray, along with a sleeve, to support layers of other bottle loaded trays above the tray at issue. The tray and sleeve, collectively, is a collapsible packaging solution that reduces freight cost and storage space requirements when empty.
The top of the milk tray is configured to include pockets for containing the milk bottles and channels to position and hold the sleeve. The bottom of the tray is configured to engage the neck of the bottle below (when stacked on a lower tray supporting bottles) to increase surface area and reduce pressure per bottle when stacked. The bottom also includes channels or other similar structure designed to engage the upper portion of the sleeve on the lower tray.
In accordance with one embodiment of the present invention, a tray for holding bottles is provided. The tray is formed from a generally rectangular sheet of material having a first side, a second side opposing the first side, a first end and a second end opposing the first end. A plurality of pockets forms depressions in the sheet. Each pocket includes a plurality of upwardly extending bottle supporting projections. Each bottle supporting projection is positioned to support a central portion of a bottom of a bottle. Each pocket further includes sidewalls having transitional ledge portions. The transitional ledge portions are positioned to support a peripheral edge of the bottom of the bottle. The tray further includes a plurality of channels separating each of the plurality of pockets.
The tray can be configured so that at least one of the plurality of pockets includes a centrally positioned upwardly extending projection. Preferably, four bottle supporting projections surround the centrally positioned projection. The centrally positioned upwardly extending projection is configured to have a transitional ledge portion positioned to support a peripheral edge of the bottom of the bottle. The centrally positioned upwardly extending projection, along with the transitional ledge portions in the sidewalls and the bottle supporting projection fully support each bottle in the tray.
The tray can further comprise an upwardly extending sleeve having panels positioned in the plurality of channels. Additionally, the tray can include a plurality of slots formed in the plurality of channels. The sleeve can include a plurality of downwardly extending tabs positioned to engage the slots. The slots and tabs help position and maintain the sleeve on the tray.
Additionally, the tray can include a plurality of bosses extending upwardly from the channels. Like the slots and tabs, the bosses also help to hold the sleeve in place.
Each bottle supporting projection can include a lower surface configured to rest on a shoulder portion of a bottle below the tray (when layers of trays are stacked on each other). This helps spread the pressure and allows for the bottles and sheet of one tray to support layers of trays above it.
The tray can be formed from a molded plastic. The sheet can also be plastic, such as a corrugated plastic having a first outer layer and a second outer layer separated from the first outer layer by a plurality of flutes. Other suitable materials can be also be used.
In accordance with another aspect of the invention, a tray for supporting bottles in a stack of bottles is provided. The tray comprises a generally rectangular sheet of material having a first side, a second side opposing the first side, a first end and a second end opposing the first end. The tray includes a plurality of upwardly extending bottle supporting projections formed in the rectangular sheet of material. The tray also includes a plurality of channels formed in the rectangular sheet of material and a sleeve having panels positioned in the plurality of channels.
The tray can also include other features mentioned herein and/or shown in the Figures.
Further aspects of the invention are disclosed in the Figures, and are described herein.
To understand the present invention, it will now be described by way of example, with reference to the accompanying drawings in which:
While this invention is susceptible of embodiments in many different forms, there is shown in the drawings, and will herein be described in detail preferred embodiments of the invention with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the broad aspect of the invention to the embodiments illustrated.
A tray 10 for supporting, transporting and/or stacking layers of structural bottles in accordance with the present invention is shown in
As shown in
The tray 10 shown in
Each of the large sections 24 for holding four bottles includes four generally conical shaped bottle resting projections 30 and a central projection 32 (having a generally rectangular cross-sectional shape) surrounded by the bottle resting projections 30. Each of the projections 30, 32 are hollow and extend upward from the lower level 34 of the tray 10. As shown in
Additionally, each of the central projections 32, along with sidewalls forming the depressions of the sections 24, includes a ledge or transition portion 36 that separates a lower portion of the sidewalls and central projections 32 from an upper portion. Each of the lower portions of the sidewalls extends further into the depression than the upper portions. With respect to each central projection 32, the lower portion extends outward further than the upper portion. That is, the base of each projection is wider than the upper portion.
The bottle resting projections 30 support a central portion of the bottom of each bottle. Together, the bottle resting projections 30 along with the ledge portions 36 of the sidewalls and central projections 32 support the central portions of the bottoms of the bottles. The ledge portions 36 support around the periphery of the bottom of each bottle. The projections 30 can also be formed to have a ledge portion.
The top surface 20 also includes a plurality of channels 28 that are formed in the upper part of the tray. The channels 28 separate each of the large pockets 24 for holding four bottles and each of the small pockets 26 for holding two bottles. The channels 28 are used to support a sleeve 38 that separates the pockets 24 and 26.
The sleeve 38 is shown in
The sleeve 38 can be formed from a corrugated material, such as corrugated paper or corrugated plastic, having a first outer layer and a second outer layer separated from the first outer layer by a plurality of flutes or other similar structure. The sleeve 38 can also be a solid structure and formed from other suitable materials.
The upper surface 20 of the tray 10 also includes a plurality of bosses 42 positioned proximate portions of the channel 28. The bosses 42 help keep the sleeve 38 in place and prevent the panels 40 from moving or slipping off the channel 28.
Additionally, the upper surface 20 includes slots 44 formed at various spots on the channel 28 as shown in
The bottle resting projections 30, in addition to supporting the bottom of a bottle 46 on the upper surface 20 of the tray 10, are configured to receive and rest on a top portion 48 of a lower bottle 46 (when one tray 10 of bottles is stacked on a lower tray 10 of bottles 46). As shown in
The sleeve 38 is also used to support additional layers of filled trays 10. That is, both the sleeve 38 and the bottles 46 (contacting the lower surface of the projections 30 of an upper tray 10), are used to support additional layers of trays 10. The sleeve 38 can be slightly higher than the tops of the bottles. Accordingly, the sleeve 38 may need to be compressed slightly (about ⅛ of an inch) before the upper tray 10 will rest on lower bottles. The lower surface of the tray 10 can also include channels 51 (see
Many modifications and variations of the present invention are possible in light of the above teachings. It is, therefore, to be understood within the scope of the appended claims the invention may be protected otherwise than as specifically described.
