MOLDED PULP CONTAINER Filed April 16, 1958 INVENTORS Harold 8. Crane Alfred E. Comstock BY KRRI. LO Loans ATTORNEY United States PatentD MOLDED PULP CONTAINER Harold 5. Crane, Palmer, Mass., and Alfred E. Comstock, Belvedere, Calif., assignors to Diamond National 1 Corporation, a corporation of Delaware Filed Apr. 16, 1958, Ser. No. 728,952
' 3 Claims. Cl. 229-45) The present invention relates to a molded pulp set-up insulating container, and more particularly to a molded pulp set-up insulating container in which six integrally joined sections have rims disposed thereon to give locking contact where free section edges meet.
Prior art containers are known which are made of molded pulp, and which are used as insulating containers for such products as ice cream. In one such prior art container, however, the construction was such that a large area of molded pulp came into contact with the material held in the container, so that there was a considerable amount of heat conducted through the pulp and into the contained product, and this was true even though molded pulp has a very low heat transfer coefiicient. Also, this known construction contemplated that the entire package would be inserted within yet another container in order, tojtrap insulating air between the walls of the outer and inner containers. Thus, this known construc tion necessitated in effect the use of'two containers in order to obtain the desired insulating characteristics.
In another form of molded pulp set-up carton or container, there wasprovided a molded pulp box blank having integrallymolded lugs on the various sections of the blank. This construction failed to provide a nestable blank, and also failed toprovide aset-up box which would adequately support a brick or carton of ice cream, and still permit. maximum utilization of-the interior space of the box, and therefore of the material of which the blank is made.
It is an object of the present invention to provide a molded pulp set-up insulating container having great insulative value.
It is yet another object of the present invention to provide a molded pulp set-up insulating container having as little pulp as possible in contact with the goods held in the container.
It is still a further object of the present invention to provide a molded pulp set-up insulating container which will support goods therein and will also entrap a blanket of insulating air around the goods.
It is a further object of the present invention to provide a molded pulp set-up insulating container made of a nestable blank.
Yet another object of the present invention is the provision of a molded pulp set-up insulating container made from an integral sheet of molded pulp and which will have maximum rigidity when set up.
A further object of the present invention is to provide a molded pulp set-up insulating container that is not only nestable and highly insulative, but that also provides a relatively rigid container.
A still further object of. the present invention is to provide a molded pulp set-up insulating container in which the sections of the blank of which the container is made have mating anti-shift walls.
Another object of the present invention is to provide a molded pulp set-up insulating container which uses a minimum amount of molded pulp to encompass a given;
volume of goods.
Other objects and the nature and advantages of the instant invention will be apparent from the following 1: scription taken in conjunction with the accompanying drawings, wherein: p t
Fig. l is a plan view of a blank in accordance with the present invention; 1 Fig. 2 is a sectional view taken on the line 2--2 of Fig. 1;
Fig. 3 is a sectional view taken on the line 3--3 of Fig. 1;
Fig. 4 is a plan view of a box set-up from the blank of Fig. l, but with the top section thereof folded back;
Fig. 5 is a sectional view on the line 5-5 of Fig. 4, but with the top section in the closed position; and
Fig. 6 is a sectional view taken on the line 66 of Fig. 4, also with the top section in the closed position.
Referring now to the drawings, there is shown in Fig. 1 a box blank or sheet 10 of molded pulp having a bottom section 12 which is generally rectangular. Bot-.
' to the bottom section 12 along one wall thereof and separated therefrom by a score line or fold 19. Section 18 has a raised arm 21 extending along the three free sides thereof; rim 21 is shaped in cross-section in the same manner as is rim 13. Side section 18 has an upstanding button 22 centrally thereof. A second side sec,- tion 23 having a continuous r-im '24 along the three free sides thereof and a centrally upstanding button 25 extends from another of the sides of bottom section 12, and a third side section 26 extends from another side of the bottom section 12 and has a continuous rim 27, extending along the three free sides and a central up standing button 28. A score 20- is provided at the junction of side section 23 and bottom section 12, and a score 29 is provided at the junction of side section 26 and bottom section 12. It will be apparent that the three side sections 18, 23 and 26 are substantially identical.
A fourth side section 30 is integrally joined to the fourth side of the bottom section 12, and has raised rims 31 and 32 extending along the two sides thereof that lie perpendicularly to the fourth side of the bottom section 12. Centrally of the fourth side section 30 is an upstanding button 33 and a score 34 is provided at the junction of side section 30 and bottom section 12.
A top section 36 is integrally joined at one side thereof to the side of the fourth section 30 that is opposite to the side of fourth section 30 that is joined to bottom section 12. Top section 36 has a score mark 37 at the junction thereof with the side section 30, and has a raised rim 38 extending along the three free sides thereof. Top section 36 is provided with a central upstanding button 39.
Referring now to Fig. 4, it may be seen that when the box blank or sheet of Fig. l is folded up so that the free sides of the four side sections 18, 23, 26 and 30 meet and mate with each other, a substantial surface engagement is obtained between the sloping exterior walls of the upstanding rims of each of these side sections, this being clearly shown at the four corners of the box. These mating corners are designated 41, 42, 43 and 44, and provide strength and rigidity to the set-up box. It will be noted that this construction provides for an absence Patented June 21, -19 60
