No. 881,996, filed Dec. 4, 1969, now abandoned.

Tubular cartons for packaging fragile articles are continually being developed. In the art of vacuum tubes, transistors, etc'., and particularly where many components are miniaturized, tolerances are rigidly controlled and thus such components must be protectively packaged against any type of shock which will disturb the designed construction.

Primary objects of the present invention are to provide a novel blank and carton in which a tubular sleeve incorporates therein novel cushioning portions, and more particularly in which interior walls are provided with rupture sections permitting a fragile article to be readily inserted in the carton and providing portions which accommodate to the configuration of the article and protectively support it against shock, mechanical damage and the like.

These, together with other and more specific objects and advantages of the invention, will become apparent from a consideration of the following description of an exemplary embodiment when taken in conjunction with the drawing forming a part hereof, wherein:

IN THE DRAWING FIG. Us a perspective view of a tubular sleeve carton incorporating the invention having a fragile article package therein;

FIG. 2 is a reduced scale plan view of a blank from which one embodiment of the carton or tubular packaging sleeve is produced;

FIG. 2a is a view similar to FIG. 2 showing a first step of assembling the blank of FIG. 2;

FIG. 2b is a view similar to FIG. 2a showing the next step of assembly in the blank of FIG. 2;

FIG. 20 is a view similar to FIG. 2b showing the blank of FIG. 2 in its assembled, folded-flat condition prior to being erected to the condition illustrated in FIGS. 1 and 3;

FIG. 3 is an enlarged sectional view of a carton assembled from the blank of FIG. 2 (similar to FIG. 4) without a fragile article inserted therein;

FIG. 4 is a sectional view taken on the plane of line 44ofFIG.1;and

FIG. 5 is a reduced-scale plan view similar to FIG. 2 and showing an alternate embodiment.

Referring to the drawings in detail, and first considering FIG. 2, a one-piece blank is produced from any suitable material such as paperboard, plastic laminates, etc. The blank 10 comprises four rectangular outer wall panels 12, l4, l6 and 18, in which panel 12 includes a free outer margin parallel to hinge lines 22-28 hingedly connecting the adjacent panels to each other as is conventional. The transverse margins of the panels conveniently include cover flaps 30, and 32, 32' at opposite ends of outer wall panels 12 and 16, respectively, and alternate side wall panelsl4 and 18 respectively include closure panels or cover flaps 34 and 36, respectively, each of which includes a foldable tuck flap 38 and 40, respectively.

I-lingedly connected to the fold line 28 is a glue flap ,42 having hingedly connected to its side margin 44 a cushioning panel array indicated generally at 46. The cushioning panel array comprises, from the fold line 44, a pair of cushioning panels 48 and 50 hingedly connected by mutually parallel fold lines 52 and 54 to a spacing panel 56. The outer margin of the cushioning panel 50 has hingedly connected to a marginal fold line 58 a securing or spacing panel 60. The outer margin of the spacing or securing panel 60 is defined by free edge 62, and the upper and lower margins of the cushioning panel array 46, as indicated at 64 and 66, are colinear with the upper and lower margins 68 and 70 of the glue flap 42, as well as with the upper and lower margins of the outer wall panels 12-18, defined either by free margins or by fold lines.

Extending vertically between the upper and lower margins 64 and 66 of the cushioning panels 48 and 50, and bisecting these panels, are rupturable tear-lines 72 and 74, respectively.

Assembly of blank 10 is as follows:

Referring to FIG. 2, adhesive is applied to. the exposed surface of flap 60, and flap 60, together with cushioning panel 50 and spacing panel 56, are folded at fold line 52 so that panel 60'will adhere to area 60' with edge 62 bordering and immediately adjacent fold line 28; see FIG. 2a. A suitable mastic or glue-is then applied to the exposed surface of connecting panel 56; see FIG. 2a, and the earlier-folded cushioning panel array 46, as indicated at 46', is folded on the fold line 28 to the position shown in FIG. 25 wherein panel 56 adheres to area 56' as shown by phantom lines on FIG. 2a.

With the panels thus assembled, and without further description, a cushioning sleeve as indicated in FIG. 3 will be automatically erected when the rectangular. outer sleeve is erected, i.e., when wall panels 14 and 18 are orientedinto spaced parallel relation as seen in FIG. 3. v r

Next, as seen in FIG. 2b, adhesive is applied to the glue flap44, as indicated by the shading, and will adhere to area 44' when panels 12 and 14 are simultane-- ouslyfolded on fold line 24 to overlie panels 16 and 18, respectively. When this is accomplished, the blank of FIG. 2 will be assembled in the condition illustrated in FIG. 2c and willremain in a folded flat storable or shipping condition until it is to be erected to the condition shown in FIG. 3.

Erection of the assembled blank is accomplished by applying pressure at opposite fold lines 24 and 28 in the manner indicated by the direction arrows indicated on FIG. 20, resulting in the tubular protective sleeve carton being assembled to the condition shown in FIG. 3 with the inner severable sleeve panels 48 and 50 being in spaced relation ready to receive a longitudinally inserted article A.

The article A (see FIG. 4) has a diameter or maximum dimension less than the distance between outer wall panels 12 and 16; and in this exemplary embodiment, for purposes of convenience, the article is indicated as having a circular cross-section, being a radio tube, for example. As the article A is inserted between the panels 48 and 50, the lines 72 and 74 are ruptured or severed thus providing essentially V-shaped opposed cushioning channels C and C which suspend and maintain the article A away from the inner surfaces of walls 12-18.

Applicant has provided a one-piece shipper sleeve for fragile articles in which a one-piece blank provides throughfold and score lines an outer packing sleeve the inner wall panel segments forming the channel C,

C and direct lateral shock will not subject the article A to damage.

For purposes of illustration, applicant has shown the article A as being substantially adjacent to the end of the tubular protective sleeve. However, suitable means will be provided at opposite ends of the packing sleeve to prevent any damage to the end portions of the article being protected and shipped.

Referring to FIG. 5, a blank having all of the structure shown in FIG. 2 is indicated generally at 110. In this embodiment, all similarly functioning and structural portions are indicated by the same reference numerals used in FIG. 2, and the blank of FIG. is assem bled and erectedvin the same manner as heretofore described in detail with respect to FIGS. 2-2cand3. Additionally, those portions which have been modified are further identified with reference numerals similar to those used in FIG. 2, however, the prefix one hun-. dred is added. For example, the cushioning panel array 146, in additionto being connected to the glue flap 42 at fold line 44 and including a separating panel 56 and second glue flap 60, includes modified cushioning panels 148 and 150.

The modification of the blank in FIG. 5 consists of sinusoidal or undulating tear lines 198 and 200 which start from the upper margins 164 and extend down to the lower margin 166 moving alternately with the peaks, as illustrated.

When the blank of FIG. 5 has been assembled and erected in the manner heretofore described with respect to the blank of FIG. 2, the sinusoidal tear lines l98'and 200 will provide an irregular break-away surface on the cushioning channels C, C formed in the manner illustrated in FIG. 4 when an article A is inserted between the cushioning panels 148 and 150.

It will be obvious to those skilled in the art that various changes may be made without departing from the scope of the invention and the invention is not to be considered limited to what is shown in the drawings and described in the specification.
