Description

Sept. l, 1964 L. MAYER INTERPACKING Filed April 11, 1965 INVENTOR LOUIS MAY ER ATTORNEYS United States Patent O 3,146,932 INTERPACKING Louis Mayer, Elmhurst, N.Y., assignor to Gwens-Illinois Glass Company, a corporation of Ohio Filed Apr. 11, 1963, Ser. No. 272,314 4 Claims. (Cl. 229-14) This invention relates to interpacking and more particularly to one-piece paperboard interpacking for maintaining an article in spaced relationship from the walls of an outer shipping container.

Important objects of this invention are the provision of interpacking that is simple and economical to manufacture and that can be quickly and efficiently assembled.

Other objects and advantages of this invention will become apparent from the following description taken in conjunction with the accompanying drawing wherein are set forth, by way of illustration and example, the preferred embodiment of this invention.

In the drawing:

FIG. l is a perspective view showing the interpacking of this invention;

FIG. 2 is a perspective view showing the interpacking of this invention assembled in a regular slotted container;

FIG. 3 is a perspective view, partly in section, showing a package assembled in accordance with this invention; and

FIG. 4 is a sectional View, taken along the line 4 4 of FIG. 3 showing an article spaced from the container by the first and second raised pads.

The interpacking of this invention is formed from a single sheet of foldably sheet-like material that is scored and folded in the manner described below to maintain an article protectively spaced from the walls of an outer shipping container. As used herein, the term maintain means to support the article relative to the container to prevent detrimental motion therebetween.

Referring to FIG. 1, there is shown a blank of corrugated paperboard that has been scored and folded in accordance with this invention. In the preferred embodiment, the blank 10 is substantially rectangular and has a series of longitudinally extending slit scores 11 that divide the blank into a series of foldably connected panels. While slit scores are preferred because they permit easier folding (they extend through one liner and the corrugated medium), regular scores can be used. The slit scores 11 divide the blank 10 into a central panel 12 which has foldably attached thereto, along opposed marginal edges, first panels 13, which in turn have foldably attached thereto second panels 14 that are of a width equal to that of the first panels. The second panels 14 have foldably attached thereto third panels 15 which in turn have foldably attached thereto fourth panels 16 that are of a width equal to the width of the third panels. Four parallel,

transverse score lines

17, 18, 19 and 20 extend across each of the foregoing panels.

In utilizing the interpacking of this invention, the first panels 13 are reversely folded to overlie the marginal edges of the central panel 12. The second panels 14 are reversely folded to overlie the first panels and form in conjunction with the first panels what will hereinafter be referred to as first raised pads extending along each marginal edge of the central panel.

The third and fourth panels (15 and 16) are reversely folded to overlie the second panels and third panels, respectively, to form what will hereinafter be referred to as a second raised pad.

The outer shipping container C shown in conjunction with the preferred embodiment of this invention is what is known in the trade as a regular slotted container. A regular slotted container comprises a tubular body portion of four foldably connected side walls 25 having top 3,146,932 Patented Sept. 1., 1964 ICC and bottom closure iiaps Z6 foldably connected to each edge thereof.

In assembly, the interpacking is folded along the

score lines

18 and 19 and telescoped into the container C. The central panel 10 has a width equal to the inside width of the container C, and the length between the

score lines

18 and 19 is substantially equal to the inside length of the container C. The article A, which in the illustrated embodiment is parallelepiped-shaped, is telescoped onto the liner and allowed to rest on and against (with respect to the now vertical portions thereof) the first raised pads. The combined thickness of the central panel 12 and first raised pad is substantially equal to the space between the article and the bottom, top, and one pair of opposed side Walls. The article A also fits between the second raised pads (formed by panels 15 and 16) which are narrower than the first raised pads. The second raised pads are proportioned to maintain the article in spaced relationship from the remaining pair of side walls of the container C. To complete the package, the pads and central panel are folded along the

score lines

19 and 20 to overlie the article. The top closure fiaps 26 of the container C are closed and secured in any suitable manner.

While only the preferred embodiment of this invention has been illustrated, it is to be understood that the relative spacings of the first and second raised pads can be varied to accommodate various sized and shaped articles. It is also to be understood that the length and transverse score lines of the interpacking can be varied to wrap about articles having various contours. Where the packaged article has protuberances, such as knobs or dials, for example, cutouts to accommodate the same can be made in the interpacking without impairing its function. Other details of construction may also be modified through a wide range without departing from the principles of this invention, and it is not, therefore, the purpose to limit the patent granted hereon otherwise than necessitated by the scope of the appended claims.

I claim:

1. Interpacking for maintaining an article in spaced relationship from an outer shipping container comprising, a central panel having an opposed pair of marginal edges, a first pair of panels overlying the marginal edge of said central panel and foldably connected thereto to extend inwardly thereof, second panels overlying said first panels and foldably connected thereto, said first and second panels forming raised pads along the marginal edge of said central panel, the thickness of said raised pads being sufficient to maintain said article spaced from the walls of said shipping container that are parallel to said central panel, third panels overlying said second panels and foldably attached thereto to form second raised pads which extend inwardly of the width of said central panel, said third panels being narrower than said first and second panels and having their inner edges spaced apart a distance equal to the width of said article, whereby said third panels will maintain said article spaced from the walls of the container that are normal to said central panel, and transverse score line extending across said panels to permit said central panel and pads to be folded about said article.

2. The interpacking defined in claim l, further including fourth panels overlying said third panels and foldably connected thereto to increase the height of said second pads.

3. Interpacking for maintaining a parallelepiped-shaped article in spaced relationship from an outer shipping container having bottom and top, and Itwo pairs of opposed side walls, comprising, a transversely scored central panel positioned adjacent and parallel to said bottom and top walls and one pair of opposed side walls of said shipping container, a pair of rst raised pads overlying opposed marginal edges of said central panel and foldably attached thereto, said rst raised pads interposed between said central panel and article and being of sufcient thickness to maintain said article spaced from said top, bottom and said one pair of opposed side walls of said shipping container, and pairs of second raised pads overlying and foldably attached to said irst raised pads, the inner edge of said second raised pads being spaced apart a distance equal to the width of said article and arranged to maintain said article in spaced relationship from the remaining opposed pair of side walls of said container.

4. Paperboard interpacking for maintaining an article in spaced relationship from the walls of an outer shipping container comprising a central panel transversely scored and arranged to wrap around said article, a pair of raised pads foldably connected to the marginal edges of the central panel and positioned between the article and the central panel, said pads being of suilcient thickness to maintain said article spaced from the wall of the container that are parallel to said central panel, a pair of second pads foldably ,connected to said rst pads, said second pads arranged on-said rst pads and in spaced apart relationship to confine the article therebetween while it is resting on said rst pads, and said second pads being of sutlicient width to maintain the article in spaced relationship from the walls of the container that are normal to said central panel.
