Definitions
- This invention relates to a container with an insert which creates a chamber though which chilled air can freely flow, thus surrounding the product contained therein.
- an air flow channel for use in a packaging container includes at least one elongated body defining at least one passage having at least one open end; and a number of spaced apart ventilation openings provided through the body along its length.
- U.S. Pat. No. 4,946,093 there is disclosed a half-slotted container body and lid, each made from a blank of corrugated paperboard.
- the lid blank has an additional score to provide a fold-line around the perimeter of the side and end panels at approximately one-half of the depth. This score line defines inner and outer panels of the lid's perimeter side and end walls. Where this fold-line intersects each of the panel score lines defining the ends of the side and end panels, there are two diagonal scores which radiate from that point in opposite directions extending to the free edge of the inner panels.
- the top flaps are folded inwardly and secured to form a top of the lid, and the inner panels are folded inwardly hinged at the four corners by the diagonal scores.
- the inner panels are pushed in at the interior four corners of the lid locking the inner panels along the outer panels to provide a two-ply perimeter wall of the lid.
- the resulting inward bulge of the inner panels of the lid creates a secure lock of the lid on the body and provides support for the sides of the body against outwardly bulging under load.
- the continuous two-ply construction of the sides of the lid provide channeling space between adjoining containers in a stacked pallet load to enhance uniform air flow and cooling of produce, such as bananas and fruits, packed in the containers.
- U.S. Pat. No. 7,637,416 suffers from the disadvantage that the ventilation openings have to be perfectly aligned in each layer of a stacked pallet. This is not easily achieved especially with the advent of the common footprint that has been adopted internationally as the preferred standard. In addition the airflow has to be horizontal in nature to be effective. Often cooling systems have vertical airflow patterns. It is also common practice for stacked pallets to be stretched wrapped with poly propylene film which totally negates the any advantage to this invention
- U.S. Pat 4,946,093 suffers from the disadvantage of blocking vertical air flow completely.
- Another disadvantage is the lid that creates the spaces only extends downward for a minimum distance so as to give a maximum exposed face of the side and end walls of the half slotted container. This disadvantage does not prevent the gap being closed during the process of banding, strapping or stretch wrapping or in transit throughout the distribution cycle thereby defeating the objective of the invention as well as creating an unstable unitized load. It is also common practice for stacked pallets to be stretched wrapped with poly propylene film which totally negates the any advantage to this invention due to the total blockage of horizontal air flow. Another disadvantage is that every container needs a lid to create the air gap. Most fruits in the global market place are shipped in a display ready open top tray eliminating any benefit of the patent.
- My invention as described in this application overcomes the disadvantages as described above, as no matter the direction of airflow or pallet stacking patterns or stretch wrapped stacked pallets chilled air is able to enter the chamber either from the side faces of the stacked pallet or from the bottom or top faces of the stacked pallet.
- the configuration of the apertures in the base and top of the chamber overcome any blocking of the apertures in the side or end walls of the container due to misalignment.
- a container includes a base, a pair of opposed end walls and a pair of opposed sidewalls, each having a series of apertures cut through the said walls to allow air to flow freely into the container and also having a series of lugs that protrude from the upper edge of said walls.
- the container includes an insert which has a pair of opposing side walls and a pair of end walls and having a series of lugs that protrude from the lower and upper edges that position the insert by means rectangular of slots cut into the base of the container and the lugs that protrude from the upper edge of the side and end walls of the container.
- the insert has a perimeter dimension that is less than the perimeter of the inner dimension of the side and end walls of the container thereby creating a channel between the wall into which air flows through the apertures in the side and end walls of the container.
- the channel surrounds the product completely.
- the insert in an additional embodiment has a series of peaks and valleys cut into the upper edge of the insert. As packed boxes are placed on top of the underlying box the peaks indent the base of the container above thus creating a friction lock thereby preventing free movement or sliding of the container.

Abstract
A container (1) which includes a base (16), a pair of opposed end walls (2) and a pair of opposed sidewalls (5) into which an insert (9) also having a pair of opposed end walls (11) and a pair of opposed sidewalls (12) is located and secured in position by tabs (14) protruding from the lower edges of the said pair of opposed sidewalls (12). A set of tabs (10) protruding from the upper edges of the end walls (11) and sidewalls. (12) The lower tabs are engaged in rectangular precut slots (8) in the base (16) of the container. (1) The upper tabs(10) are held in position by tabs(4) which are bent at right angles to the end and side walls (2&5) respectively and which have precut rectangular slots(7) which engage the lugs protruding from the pair of end walls (2) and side walls (5) of the insert. (9) The engagement of the lugs (14) and (10) position the insert (9) thus creating a gap between the side walls (2&5) and the sidewalls (11&12) of the insert. (9) This gap forms a chamber (15) around the insert (9) though which air can freely circulate around the product contained within the inner walls of the insert (9)

U.S. Patents Patent Number Kind Code Issue Date Patentee 76/337,416 A1 Dec. 29, 2009 Moelich; Leuvennink; Dippenaar 4,946,093 Aug. 7, 1990 Moorman 2,858,059 October 1958 Kitchell - It is well documented that fresh produce which is transported in containers need adequate cooling to maintain peak quality and shelf life throughout the distribution cycle. Currently containers are packed with produce then stacked on pallets in a predetermined pattern ready for shipment to the market place. Each layer of containers are stacked with their faces abutting the face of the container alongside so as to create a solid block or unitized load which can be strapped together so as to maintain stability throughout the distribution cycle. Unfortunately this practice prevents chilled air from flowing to the inner faces of the containers which abut each other. To try and remedy this situation box designers cut apertures in the side walls in the hope that chilled air will flow though the aperture on the outer face, past the product through the aperture in the opposite face of the container into the next abutting container. This method is not efficient and is limited by the number of apertures cut into the side walls of the container as each time an aperture is cut the compression strength of the container is compromised. Other criteria for maintaining produce quality is the ability for the containers to maintain circulation of ventilating air or gas to the fruit contained within the containers and for removal of heat generated by respiration of the fruit contained within the containers. There have been some attempts to address the cooling and venting challenges and are described in the following patents:
- U.S. Pat. No. 7,637,416 According to the invention, an air flow channel for use in a packaging container includes at least one elongated body defining at least one passage having at least one open end; and a number of spaced apart ventilation openings provided through the body along its length.
- U.S. Pat. No. 4,946,093. According to the invention, there is disclosed a half-slotted container body and lid, each made from a blank of corrugated paperboard. The lid blank has an additional score to provide a fold-line around the perimeter of the side and end panels at approximately one-half of the depth. This score line defines inner and outer panels of the lid's perimeter side and end walls. Where this fold-line intersects each of the panel score lines defining the ends of the side and end panels, there are two diagonal scores which radiate from that point in opposite directions extending to the free edge of the inner panels. When the lid is set up, the top flaps are folded inwardly and secured to form a top of the lid, and the inner panels are folded inwardly hinged at the four corners by the diagonal scores. The inner panels are pushed in at the interior four corners of the lid locking the inner panels along the outer panels to provide a two-ply perimeter wall of the lid. The resulting inward bulge of the inner panels of the lid creates a secure lock of the lid on the body and provides support for the sides of the body against outwardly bulging under load. The continuous two-ply construction of the sides of the lid provide channeling space between adjoining containers in a stacked pallet load to enhance uniform air flow and cooling of produce, such as bananas and fruits, packed in the containers.
- U.S. Pat. No. 7,637,416 suffers from the disadvantage that the ventilation openings have to be perfectly aligned in each layer of a stacked pallet. This is not easily achieved especially with the advent of the common footprint that has been adopted internationally as the preferred standard. In addition the airflow has to be horizontal in nature to be effective. Often cooling systems have vertical airflow patterns. It is also common practice for stacked pallets to be stretched wrapped with poly propylene film which totally negates the any advantage to this invention
- U.S. Pat 4,946,093 suffers from the disadvantage of blocking vertical air flow completely. Another disadvantage is the lid that creates the spaces only extends downward for a minimum distance so as to give a maximum exposed face of the side and end walls of the half slotted container. This disadvantage does not prevent the gap being closed during the process of banding, strapping or stretch wrapping or in transit throughout the distribution cycle thereby defeating the objective of the invention as well as creating an unstable unitized load. It is also common practice for stacked pallets to be stretched wrapped with poly propylene film which totally negates the any advantage to this invention due to the total blockage of horizontal air flow. Another disadvantage is that every container needs a lid to create the air gap. Most fruits in the global market place are shipped in a display ready open top tray eliminating any benefit of the patent.
- My invention as described in this application overcomes the disadvantages as described above, as no matter the direction of airflow or pallet stacking patterns or stretch wrapped stacked pallets chilled air is able to enter the chamber either from the side faces of the stacked pallet or from the bottom or top faces of the stacked pallet. The configuration of the apertures in the base and top of the chamber overcome any blocking of the apertures in the side or end walls of the container due to misalignment.
- This invention has a number of embodiments that emanate from its novel design, some of which are described in the following claims, drawings and text.
- According to the invention a container includes a base, a pair of opposed end walls and a pair of opposed sidewalls, each having a series of apertures cut through the said walls to allow air to flow freely into the container and also having a series of lugs that protrude from the upper edge of said walls.
- The container includes an insert which has a pair of opposing side walls and a pair of end walls and having a series of lugs that protrude from the lower and upper edges that position the insert by means rectangular of slots cut into the base of the container and the lugs that protrude from the upper edge of the side and end walls of the container.
- The insert has a perimeter dimension that is less than the perimeter of the inner dimension of the side and end walls of the container thereby creating a channel between the wall into which air flows through the apertures in the side and end walls of the container. The channel surrounds the product completely.
- The insert in an additional embodiment has a series of peaks and valleys cut into the upper edge of the insert. As packed boxes are placed on top of the underlying box the peaks indent the base of the container above thus creating a friction lock thereby preventing free movement or sliding of the container.
