tubes manufactured in mass production. Many of the cartons, particularly those made of cardboard or corrugated board, are of such internal construction as to more or less firmly support the article, and yet keep it spaced from the sides of the carton so that the article may not he injured due to impacts directed against the sides of the carton. It has, however, been found that the supporting structure, while keeping the fragile article centrally disposed within the carton, does not provide a sufciently yieldable or resilient support so as to render it safe from the danger of breakage when forcefully brought into actual contact with the supporting structure itself. Where attempts have been made to provide a resilient structure, the resultant carton has generally been intricate in structure and high in cost.
It is within the contemplation of our invention to provide a carton with the aforesaid shortcomings eliminated, whereby a fragile article such as a radio tube may be safely supported centrally within a carton, and separated from the walls thereof, without any danger of breakage due to impact engagement with the supporting structure. And it is a further important object of our invention to enable a yieldable support to .be effectuated by means of a structure of simple, readily fabricated and inexpensive design.
It is also within the contemplation of this invention to provide a carton with an arrangement of simply constructed inserts adapted not only to provide the yieldable support above referred-to, but also to 'snugly accommodate the article by cupportably engaging it at two differently proportioned portions thereof.V
It is another object of this invention to provide a carton of the above-described category with yieldable retaining walls and with limiting means engageable with the fragile article to hold it against movement beyond predetermined limits.
Other objects, features and advantages will appear from the drawing and the description hereinafter given.
Referring to the drawing,
Figure 1 is a perspective view of one of the carton retainer inserts in accordance with our invention, a portion of one of the retainer walls being broken away for clarity.
Figure 2 is a, perspective view of another insert, substantially similar to that of Figure 1 and adapted for cooperative use therewith in our invention.
Figure 3 is a disassembled view, in reduced size of the unit of Figure 1.
Figure 4 is a vertical section of a conventional outer casing of rectangular cross-section, showing the units of Figures land 2 in an operative position therein, and supporting a radio tube, two of the .retainer walls being shown, in broken lines, flexed outwardly.
Figure 5 is a vertical section of a modification of our invention containing three retainer inserts and two horizontal retainer walls between the inserts, certain of the retainer walls being shown, by broken lines, in their flexed positions, and
Figure 6 is a perspective view of one of the retainerv walls employed'in our invention.
'Ihe retainer units employed in the preferred form of our invention are illustrated as the units I0 and II, unit I0 being superimposed upon unit Il within the conventional type of outer casing I2. Unit I0 consists of two parallel vertical walls I3 and I4, containing slots extending downwardly from the upper edges I5 and I6, respectively. Wall I3 contains slots I1 and I8, and wall I4 contains slots I9 and 20. In-interlocking engagement with said walls I3 and I4, and preferably at right angles thereto, are the vertical parallel walls 2I and 22 containing slots extending upwardly from the lower edges 23 and 24 thereof, respectively. Wall 2l contains the slots 25 and 26 and wall 22 4contains the slots 21 and 28.
Unit II contains a similar arrangement of interlocking walls, 29, 30, 3| and 32. Inasmuch as the interlocking arrangement is substantially similar to that of unit I0, a detailed description thereof will not herein be given. It is, however, understood that the invention is not limited -to the particularly slotted arrangement specifically shown in Figures 1 to 3, inasmuch as other wall supporting means may be employed within the scope and intent of this invention.
Referring specifically to the form of our invention illustrated, it is apparent that sections 33 and 34 of walls I3 and I4, respectively, can, if made of bendable material, be flexed inwardly or outwardly. Figure 4 illustrates an outward exing of said sections. Similarly, sections 35 and 36 of walls 2i and 22 can' be exed inwardly or outwardly under the influence of suitable forces applied thereto.
In the specific arrangement shown in Figure 4, the upper portion 31 of radio tube 38 is normally in proximate relation to sections 33 and 34 of walls I3 and I4, and also to walls 2| and 22- and if desired the unit can be so proportioned with respect to the tube that the tube will actually 'engage said walls. Unit II is so proportioned'that the upper edges 39, 40, 4I and 42 engage the annular wall 43 of the radio tube so as to prevent a downward movement thereof. In otherwords, the upper portions of walls 28, 38, 3| and 32 of unit II serve to support the tube 38 in suspension. It is preferred, although not required, that' the walls of said unit Il be so proportioned as to 'be either in actual engagement or in proximate relation to the base or bottom 44 of tube 38. Inasmuch as the radio tube is of greater proportions in itsyupper portion than in its lower portion, the central chamber 45 in unit I 8 is of larger proportions than the central cham- 20 ber 48 of unit II.`
It Will further be observed that inasmuch as the slots of the walls constituting units I8 and II are disposed intermediate the lateral edges of the respective walls, they provide a plurality of cells surrounding the central chambers 45 and 48. For example, in'Figure 4, "the upper unit I0 is provided with cells 41 between the I.central chamber 45 and the sides 48 of the outer, casing. Similarly, tween the central chamber 48 and the .sides 48 of the outer casing.
When the device is in operative use, the fragile article, such as the radio tube 38, is suspended centrally oi the container. The arrangement is hence such that it is protected by the air spaces 41 and 48 from impacts that may be directed against the sides 48 of the casing. Being suspended,.both the upper and lower portions of the tube are out of contact with the sides, top or bottom of the outer container. In this case it should be observed that if the top of the container were lled with some resilient material, such as excelsior, the tube would be prevented from shifting in the event the carton were inverted.
Should the carton be subjected to sudden impactsthe tube 38 might be forcefully directed against one of the adjacent vertical walls. For example, the upper portion 31 of the tube might i' be directed against any of walls I3, I4, 2| or 22. If these were made of corrugated board or some slightly bendable material, there would be sufcient give to prevent danger to the tube, since the flat or bendable portions of these walls are engageable with the tube. These walls, being .-vertical, constitute in effect bendable columns if a force is applied intermediate the upper anld/ lower edges thereof. This is in contradistinctio to certain known arrangements where an unyielding edge of a wall is arranged for abutment with the tube. If the tube were suddenly directed against walls I3 or I4, the sections 33 or 34 thereof would flex outwardly as shown in Figure 4- thereby preventing any damage to the tube. In like manner, the walls of unit II are adapted to yieldably receive the lower portion of the tube when the cart-on is subjected to sudden forces.
Referring to/the form of our invention illustrated in Figure 5, units I8 and II are disposed within the walls 48 of the outer casing shown.
, In addition, there is another unit 50, preferably proportioned like unit I 0 but of less he ght, and inverted so that the walls 33a and 34a are disposed at the bottom and in adjacent relation to the lower unit II contains cells 48 be- 30 .prising flexible walled means is the flat horizontal board 5I containing a' central aperture 52 of greater proportions than the normal distances between Walls I3 "and I4. Similarly a horizontal board 53 is disposed between units I0 and II, having a central aperture 54 proportioned larger than the distances between walls 39-and 40, and the distances between walls 4I and 42. i
In the operative use of the structure of Figure 5, it is apparent that the annular wall of aperture 52 will limit the lateral movement of the tube, in the event walls 33, 33a, 34 and 34a yield more than a predetermined amount. In other words, if the force of impact is sufficiently great to cause a considerable flexing or buckling of the walls surrounding the tube, the horizontal boards 5I and ,53 come into play by preventing an excessive movement of the tube. Inasmuch as the surrounding walls had already softened the blow, any contact of the tube with the annular walls of aperture 52`and 54 will be gentle in nature, with the danger of injury reduced to a minimum.
In both forms of our invention, readily fabricated retainer inserts are employed without the necessity of employing specially formed or diecut retaining walls. It is apparent that only fiat partitions are employed, yet they are capable, if suitably proportioned, of accommodating variously sized devices, and of affording protection to a fragile article in the event the carton is subjected to impacts or other rough handling.
It is understood that this invention is not limited to the particular forms thereof illustrated 0 and hereinabove described, inasmuch as other embodiments thereof may be employed within the intent and scope of this invention, and the scope of the appended claims.
