Nov. 1935. H, G. ENHOLM ET AL PACKAGE CONTAINER Filed Sept. 7, 1934 Patented Nov. 5, 1935 STATES ATET OFFICE PACKAGE CONTAINER of Massachusetts Application September 7, 1934, Serial No. 743,056

3 Claims.

The present invention relates to containers designcd for the handling and shipment of articles Which are primarily fragile or perishable, and Which must be protected against damage in handling or insulated against extreme variations in temperature.

The purpose and object of the invention is the provision of a container embodying inner and outer closures simpl and adequatelymaintained in a permanent spaced relationship. With this general object in view, I have found that the provision of wound paper tubes of generally cy- Iindricai form, out to a length approximating the height of the outer closure, and each having a generally rectanguiar slot provided midway between opposite ends, and designed to receive a corner of the inner package, is well suited for the purpose. The diameter of the tubes is proper1y ccordinated with the space between the inner and coter closures in order that the tubes shall ccmpieteiy fi11the space at the corners and maintain the inner package against substantial movement with respect to the outer ciosure. The space between the closures may be loft either free for the circulation of air, or if desired, provided with any suitable form of insulating medium.

In the accompanying drawing, Fig. 1 represents a perspective in outline of the double-walled package with the corner supports, the inner package being indicated by dotted fines to avoid confusion; and Fig. 2 represents one of the supporting tubes employed for spacing the inner package.

Referring particulafly to the iilustrated embodiment oi the invention, the outer closure is indicated at iii, and the inner package at !2. Both closures in the illustrated embodiment of the invention are rectangular in outline, and the inner package is intended to contain confectionery or the like. The outer closure may be provided with ventilating openings 28, which provide for circulation of air about the inner package. The inner rectangular package 52 is supported in complete1y spaced relation to the outer closure by a series of corner tubes shown more particular- 1y in Fig. 2, each cf which may be convenientiy formed from a iength of wound paper or fibre tub-- ing l4, having a rectangular s1ot 16 extending through the wa1i approximatcly midway between opposite ends. The s1ot corresponds in length to the height of the inner package to be supported, and is of sufcient size t0 permit substantiel projection of the corner of the package into the tube.

In assemb1ing the inner package may be provided with a corner post assembiy upon each of the four corners, and then the entire assembiy, including the inner package and corner poste, received Within the outer ciosure, the diameter of the corner posts being such that they completeiy fil] the space between the two closures and insure predetermined and uniform spacing 01 the two c1osures with respect to one another. The supporting tubes are of sufiicient rigidity to proper1y maintain and support the inner package during handiing and shipment, and when the outer closure is covered, are prevented ircm endwise movement therein, as the height corresponds to the interior height of the closure.

In the use of this spacing construction, the two c1osures ma;v be 1eft with a free space surrounding the inner closure communicating with the ventilating openings, or if sodesired, the Ventilating openings may or may not be dispensed with, and the space provided with insulating material of any suitabie character.

What is claimed is:

1. A package container comprising an outer closure having corner portions, and cy1indrical tubes positioned in the corners thereof, each provided with a supporting slot extending through the wall between opposite ends of the tube, the slots approximating the height of an inner package and designed to receive the corners of such a package and support it in compietcly spaced relation to the outer closure.

2. A package container comprising an outer closure having corner portions, an inner package, and a slotted paper tube engaging the corners of the inner package and projecting therebeyond at the top and bottom, the tubes being of predetermincd diameter and designed tocomploteiy fill the space at the corners separating the inner package from the outer c1osure and maintaining the package in spaced relation to the outer closure both at the top and bottom and sides.

3. Spacer tubes for a double container having corner portions comprising a predetermined length of wound paper tube having a generafly rectangular slot formed therein approximatoly midway betWeen opposite ends of the tube, and designed to receive and close1y engage the corne! of a package to be supported thereby.
