Abstract

An isolator includes a first section, a second section, and a third section is disclosed. The first section is configured to secure the isolator in a mount that is defined through a mounting section. The second section is disposed over the first section and is configured to be supported by a first surface of the mounting section. The third section is disposed on top of the second section such that the second section is sandwiched between the first section and the third section. The second section dampens forces exerted on the third section or the first section from being transmitted therebetween. A method for manufacturing a pallet that is configured to be frozen is also disclosed. The method includes friction stir welding along a first joining edge and second joining edge that are abutted together to joined together to form a first segment.

First claim

What is claimed:

1 . An isolator comprising:
a first section configured to secure the isolator in a mount defined through a mounting section; a second section disposed over the first section and configured to be supported by a first surface of the mounting section; a third section disposed on top of the second section such that the second section is sandwiched between the first section and the third section, the second section dampening forces exerted on the third section or the first section from being transmitted therebetween; and a dampening plate disposed between and separating the second section from the third section, the dampening plate configured to distribute forces from the third section to the second section.

2 . The isolator according to claim 1 , wherein the first section includes a first portion and a second portion, the first portion sized and dimensioned to prevent the first portion from passing through the mount, the second portion extending from the first portion and sized and dimensioned to pass through the mount.

3 . The isolator according to claim 2 , wherein the second portion is sized and dimensioned to fill the mount.

4 . The isolator according to claim 2 , wherein the first portion is configured to engage a second surface of the mounting section that is opposite the first surface.

5 . The isolator according to claim 2 , wherein the second section includes a collar portion that defines a cavity that receives the second portion of the first section therein.

6 . The isolator according to claim 5 , wherein the second section includes a disc portion disposed over the collar portion and the second portion of the first section received in the cavity.

7 . The isolator according to claim 1 , further comprising a fastener that passes entirely through the first section, the second section, and the third section, the fastener securing the first section, the second section, and the third section together.

8 . The isolator according to claim 1 , wherein the first section is formed of a first material, the second section is formed of a second material, and the third section is formed of a third material, a shore hardness of the second material being less than a shore hardness of the first material or the third material.

9 . The isolator according to claim 1 , further comprising a top plate disposed on top of the third section, the isolator configured to support a load resting on a top surface of the top plate.

10 . A bulk shipper assembly comprising:
a pallet having a rectangular top section, the top section defining a mount passing through the top section adjacent each corner of the rectangular top section, the top section having a first surface and a second surface opposite the first surface; and an isolator disposed in each mount, the isolator configured to support one or more containers on the pallet, each isolator comprising:
a first section securing the isolator in a respective mount of the pallet;
a second section disposed over the first section and supported by the first surface of the top section such that a portion of the top section is disposed between the first section and the second section;
a third section disposed on top of the second section such that the second section is sandwiched between the first section and the third section, the second section dampening forces exerted on the third section or the first section from being transmitted therebetween; and
a dampening plate disposed between and separating the second section from the third section, the dampening plate configured to distribute forces from the third section to the second section.

11 . The bulk shipper assembly according to claim 10 , wherein the first section of each isolator includes a first portion and a second portion, the first portion disposed against the second surface of the top section to prevent the first portion from passing through the mount, the second portion extending from the first portion and passing through a respective mount of the top section.

12 . The bulk shipper assembly according to claim 11 , wherein the second portion of each isolator fills the respective mount.

13 . The bulk shipper assembly according to claim 11 , wherein the second section includes a collar portion that defines a cavity, the cavity receiving the second portion of the first section therein.

14 . The bulk shipper assembly according to claim 13 , wherein the second section includes a disc portion that is disposed over the collar portion and the second portion of the first section.

15 . The bulk shipper assembly according to claim 10 , wherein each isolator includes a fastener that passes entirely through the first section, the second section, and the third section, the fastener securing the first section, the second section, and the third section together.

16 . The bulk shipper assembly according to claim 15 , wherein each fastener includes a nut disposed adjacent the third section, the nut threadably coupled to a shaft of the fastener.

17 . The bulk shipper assembly according to claim 16 , further comprising a container mounted on the nut of each fastener such that the container is supported on the pallet, the bulk shipper assembly capable of passing ASTM D4169 DC-2 (2017) protocol at assurance levels 1 and 2.

18 . The bulk shipper assembly according to claim 10 , wherein the second section separates the third section from the pallet such that the third section is out of engagement with the pallet.

19 . A method of assembling an isolator, the method comprising:
inserting an upper portion of a first section of the isolator through a mount opening defined through a top segment; positioning a second section of the isolator over the first section and engaged with a first surface of the top segment; placing a dampening plate over the second section of the isolator; and setting a third section on the dampening plate such that the dampening plate separates the second section from the third section, the second section configured to absorb forces from the third section via the dampening plate.

20 . The method according to claim 19 , further comprising:
securing a fastener through the first section, second section, and third section to secure the isolator within the mount opening; and mounting a fluid container on a nut of the fastener to secure the container to the isolator.
