Claims.

This invention relates to article isolating shipping containers and has for its object to provide a container which will support a fragile article in such manner as to protect it against damage in shipment and which is also designed to support heavy articles out of contact with the walls of the container and to brace the walls of the container in such manner that a relatively light paperboard carton may be used as a shipping container.

A further object of the invention is to provide an article isolating buffer of simple and inexpensive construction which can be quickly and easily assembled with the article to be shipped in a carton of conventional construction.

Reference should be had to the accompanying drawings forming a part of this specification in which:

Figure 1 is a side elevation of a shipping container embodying the invention, a portion of the container being broken away and shown in section;

Fig. 2 is an end elevation of the container with a portion broken away and shown in section;

Fig. 3 is a perspective view of one of the article isolating buffers showing the manner in which paperboard partition and pocket forming members are joined together to form the buffer;

Fig. 4 is a plan view of the blank from which the partition member is formed; and

Fig. 5 is a plan view of the blank from which the pocket member is formed.

In the accompanying drawings the invention is shown applied to a shipping container in the form of a conventional paperboard carton. This carton has end walls I and 2 which may be the top and bottom of the container, the end walls ί and 2 being joined by enclosing walls 3 and 4, the walls 3 being the side walls and the walls 4 the end walls of a rectangular enclosure.

The article to be shipped is supported within the container by means of a pair of article isolating buffer members positioned adjacent the end walls I and 2. The body of the buffer is in the form of a partition member 5 that has side flanges 6 and end flanges 7 which serve to space the partition from an end wall of the container. The partition member 5 is preferably formed of paperboard and, as shown in Fig. 4, the side flanges 6 are joined to the body of the partition member by fold lines 8 and the flanges 7 are joined to the body of the partition member by fold lines 9. The corners of the blank are cut away to provide the flanges 6 and 7 with end edges 10 and 11 which are close together and parallel when the flanges (Cl. 229—14) and 7 are turned down to a position at right angles to the body of the partition as shown in Fig. 3.

To the inner face of the partition member 5 there is secured a pocket member also preferably formed of paperboard and forming an article positioning pocket having side walls 12 and 13 and end walls 14 and 15. The pocket walls are spaced inwardly from the side edges of the par10 tition member 5 and the pockets of the two opposed buffer members, which may be of identical construction, serve to position an articlecentrally of the container and spaced from the side and end walls 3 and 4 thereof.

As shown in Fig. 5, the walls 12,13, 14 and 15 are connected by fold lines 16, 17 and 18, and the blank is formed with a longitudinal fold line 19: that extends the full length thereof. The portion of the blank on the side of the fold line 19 opposite the portion forming the walls 12, 13, 14 and 15 is provided with slits 20, 21 and 22 which are alined with the fold lines 16, 17 and 18. The slits 20, 21 and 22 separate portions 23 and 24 which are connected to the walls 12, 13, 14 and

15 by the fold line 19. The fold lines 16, 17 and 18 permit the blank to be folded to form a rectangular pocket as shown in Fig. 3, with the walls 12 and 13 forming the sides of the pocket and the walls 14 and (5 forming the ends of the 30 pocket. The fold line 19 permits the portions 23 and 24 to be bent at right angles to the walls 12, 13, 14 and 15 and the form flanges which lie flat upon the partition member 5.

The pocket wall 15 is joined to the pocket wall

12 by suitable means such as a tape 25 and the flanges 23 and 24 which form base flanges of the walls 12, 13, 14 and 15, are secured to the partition member 5 by suitable means such as staples 26. The width of the flanges 23 and 24 is such that their outer edges are flush with the side and end edges of the partition member 5, and the base flanges 23 and 24 together with the portions of the partition member to which they are attached provide a buffer between the pocket walls and the enclosing walls of the shipping container.

In assembling the buffer members with the article to be shipped in the shipping container, the bottom buffer member is placed in the container with the outer faces of the flanges 6 and 50 7 in engagement with the container walls 3 and 4 and the edges of the flanges 6 and 7 in engagement with the end wall 2 of the container. An article may then be placed in the pocket formed by the walls 12, 13, 14 and 15 of the buffer mem55 ber within the receptacle and a similar buffer

2,653,418 fiiay be fitted into the upper end of the container with its pocket receiving the upper end of the article, after which the cover of the receptacle may be secured in place.

The flanges of the partition members space 5 the partitions from the end walls of the shipping container and the partition members brace the enclosing walls _spf the container mid also serve as buffers to protect the article against damage by impacts against the sides of the container. The 10 base flanges of the pocket members, which extend from the pocket outwardly to the edges of the partition members, additionally brace the side walls and add to the rigidity of the buffer.

It is to be understood that in accordance with the provisions of the patent statutes, variations and modifications of the specific devices herein shown and described may be made without departing from the spirit of the invention.
