6 Claims. (01. 20665) This invention relates to the art of packing articles for carriage and shipment, the invention being more particularly. related to an improved method and device whereby to pack small articles of a soft and delicate character in a safe,

nonshiftable and nominjurious'manner.

The invention is peculiarly adapted, although not confined, to the production of packing for firmlyjmounting and safely retaining soft and pliable collapsible tubes of the kind commonly employed in marketing pastes, cements and other substances orcommodities.

More particularly the purpose and, object of the invention are to provide certain improve 2 compartments and they are individually held at are not entirely walled in, but are open at opposite sides where the soft symmetrically round- 3 ed 'bodies of the tubes are easily distorted. Ac

I confront either openfspaces or empty corners,

while their longitudinal edgesobliquely contact with swingablepasteboard flaps which constitute divisions or partitions between the tubes.

4 The packing devices of my invention may con adapted to contain a plurality of collapsible .tubes. The units canbe brought together or loosely assembled in a compact symmetrical structure "tubes during shipment.

In brief, the object and purpose of the inven-,

tion are to provide a simple, practical and enicient packing, by the use of which the product of'themajnufacturer will reach the dealerin a presentable condition for sale or for display. on

the counter.

Withfthe foregoing andother objects in View, the invention consists in the mode of produc tion, and in the construction andrelative artheir. rigid outlet necks at determinate positions; The spacesconstituting the cells for thetubes cording to a feature of my improved packing;

sist of a plurality of units, each of which is adapted to fit snugly within a box or carton and so as tojavoid any crushing or distortion of the rangement of parts so combined asto coact and cooperate with each other in the accomplishment of the results herein contemplated, and comprises in its development the simple and practical examples illustrated in the accompanying drawing,

wherein similar reference characters designate corresponding parts throughout the several views, and in which Figure 1 represents a plan view of a blank form which is cut and creased for the production of565 a packing according to my invention;

Referring in detail to the accompanying drawing,'the reference. character 10 designates a sheet of cardboard, pasteboard or other suitable stock material from which inexpensively to produce a packing unit. j I f Thisshe'et along one edge is cut so as to providea seriesof spaced apart eyes 1 1 and converg-' ing openings or entrance ways; 12 leading to the eyesf These open eyes may be given any par--' ticular formor shape as may be necessary in85,

order'firmly to secure therein the articles to be packed. In the present embodiment, the eyes are represented as offcirculariorm for receiving the rigid neck or ojutlet ends 13 of the collapsible tubes 14.

. The sheet 10 is provided, with a crease or score line 15 which extends transversely thereof and parallel with the edge lfieontainingthe entrances to the open eyes. Said score line islocated at such distancefrom the edge 16 as will provide a shelforilange l'lof a width sufiicient to permit the accommodation therebelow of the articles to be packed. As'clearly represented in Fig. 2, the

shelf is, bentlaterally along the score line 15 so asto occupy a position substantially at right angles ,to the body of the sheet 10, the purpose being to retain the pack alongside the body of the sheet 10 the articles which are, engaged in the open eyes 11.

Thebody of the sheetlO is cut to produce alternating slots and webs l8 and 19; and. the mate rial resultingfrom the production of the slots 18 constitutes flaps or partitions 20 which are in tegral withthe webs, being swingably joined therewith alongfthe lines J21. The slots 18, webs 19 and flaps 20 extend longitudinally of the body and the ends thereof, adjoining the shelf 17, coincide with the line of crease 15. In the present instance, the slots, webs and flaps are of elongated form in correspondence with the elongated forms of the collapsible tubes 14. The slots and flaps, at the ends thereof remote from the shelf 1'7 are rounded as at 18 and 20 in order best to compensate for the rounded portions 22 of the collapsible tubes.

As previously pointed out, the collapsible tubes are attached to the shelf by inserting their rigid neck portions 13 in the open eyes 11, and it will be noted in this connection that the application of the neck portions to the eyes is so made that the cone-shaped ends 23 of the tubes come at the inner face of the shelf while the caps 24 of the tubes engage over the outer face of the shelf. Preferably and as shown, the tubes are applied to the eyes in such manner that the widthwise thicknesses of the tubes between their opposite longitudinal edges 25-25 occupy positions obliquely with respect to the plane of the sheet 10. In this way the rear faces of the tubes confront the slots 18 and empty corners between the webs 19 and adjacent flaps 20 while the front faces of the tubes confront the open sides of the structure which exist between the partition flaps 20. Moreover, under this arrangement, one of the longi- 'tudinal edges of each tube confronts the open avoid any crushing or distortion of their soft bodies.

According to an important feature of my invention, the flaps 20 which constitute partitions between adjacent tubes, are in engagement with the inner face of the shelf 17 so as to prevent any sagging of the shelf due to the Weight of the tubes which are attached thereto.

The end of the sheet 10, opposite to the shelf 17 may, if desired, be provided with a crease line 26 from which may be bent a foot portion 27.

In the case of single tray units, the foot portion may be entirely omitted; for the flapsZO may themselves be utilized as spacing means whereby .to space the body of the sheet 10 from an oppo- "site side wall of the box or carton into which the tray unit is placed. Said foot 2'7, which may be bent in a direction opposite to the bend ing of the shelf 17 as best shown in Fig. 2, lies in a plane parallel with the plane of the shelf '17, and said foot 2'7 when thus established, has

special utility as a spacer in connection with a similar adjoining tray unit.

The single tray unit, with or without a foot portion as 27, is made in such size that when the shelf 17 thereof is bent into lateral position for engagement with the laterally extending flaps, it will fit snugly within the walls of the shipping box or container. Thus, in Fig. 4, it will be noted that the opposite edges 28-28 of the sheet "10 have frictional contact with the opposite sides 2929 of the shipping container 30. The caps 24 of the collapsible tubes, positioned at the outer face of the shelf 1'7, engage with one end :31 of the container; and with the opposite end tioned that the ends 33 of the collapsible tubes are in spaced relation to the end wall 32 of the container in which the unit is placed. By this provision, the free ends 33 of the collapsible tubes cannot become crushed or distorted. Since the shelf i7 is held against sagging by the pluralityof iiaps 20 and since the caps 24 of the tubes are maintained in firm engagement with the inner face of the carton wall 31, the collapsible tubes are firmly held against any shifting movement tending to bring about crushing or distortion of their soft bodies. The provision of the flaps 20 as partitions between the tubes also render service by way of preventing distortion of the bodies, since such flaps are hingedly engaged for free movement and consist of relatively yieldable pasteboardor the like.

In Fig. 3, an assembly of two tray units is illustrated. The upper unit 34 is made precisely like the unit illustrated in 1 and includes the foot portion 27 bent in a direction opposite to that of the shelf so as to afford spacing means between the upper unit 34 and the lower unit 35. Said unit 35 is also similar in all respects to the unit illustrated in Fig. 1, except that the foot 27 is omitted. It will be noted that these two units are assembled with their shelves in a common plane; and that the shelf for the unit 35 constitutes spacing means for such unit at the end thereof opposite to the foot 2'7. These two units, as a compact structure, may be installed in a box or carton of proper size, in the same way as described in connection with the installation of the single unit illustrated in Fig. 4.

From the foregoing description, taken in connection with the accompanying drawing, it will be seen that I have provided a very simple, practical and efficient packing device for collapsible tubesand similar articles, and one which is composed of few parts, cheap to manufacture, apply and assemble in units.

Although in the present embodiment of the invention, there is shown in Fig. 3 a packing structure comprising two tray units, it is to be understood that any number of units could be employed as this does not affect the principle of the invention.

It will be manifest that I have disclosed a thoroughly satisfactory mode of packing collapsibletubes and a mode which embodies the features of advantage enumerated in the statement of the invention and the above description, and while I have, in the present instance, shown and described the preferred form of the tray device forcarrying out the invention in practice, it is to be understood that the particular construction of the tray device is susceptible of modification in various particulars without departing from the spirit or scope of my invention or sacrificing any of its advantages.
