Patented Feb. 13, 1951 UNITED STATES TENT QEEIQE CARTON FOR CUSHIONED SHIPPING AND DISPLAYING FRAGILE ARTICLES 13 Claims. I

Ihis invention relates to shipping cartons for packaging fragile articles such as those made wholly or partly of glass, and more particularly is directed to an improvement of a carton which is constructed to support fragile articles therein cushioned to absorb shocks and strains in transportation and when roughly handled.

Among the objects of the invention is to provide a carton for cushioned shipping and displaying fragile articles of the character described comprising few and simple parts, which shall be readily assembled from a single blank sheet ma terial such as corrugated paper board to form a carton container or receptacle of inexpensive construction having integral cushioning means for supporting a fragile article within the carton against damaging from rough handling in shipping and storage, which shall form a display means of neat and attractive appearance for an article packed therein when partly open, and which shall be practical and efficient to a high degree in use.

Other objects of the invention will in part be obvious and in part hereinafter pointed out.

The invention accordingly consists of the features of construction, combination of elements and arrangement of parts which will be exemplified in the construction hereinafter described, and of which the scope of the application will be indicated in the following claims.

In the accompanying drawing in which is shown one illustrative embodiment of this invention:

Fig. 10 is a top elevational view corresponding to the assembly shown in Fig. 9 showing the top panel side of the carton cut away to expose the interior construction with details of the top and side cushioning supporting arrangement surrounding said enclosed vanity case, and

Fig. 11 is an enlarged cross sectional view showingv alternative means for safely packing the mirror in the carton when dismounted from the vanity case using member portion of blank shown in Figs. 1 and 6 as a cushioning spacer interposed between the mirror and the vanity case.

Referring now to the drawing. In Fig. 1, a blank 20 may be cut and scored from suitable sheet material such as corrugated paper board of any well known manufacture used for making shipping cartons and containers. In practicing the invention for economy and to avoid waste, the blank 20 is out rectangular in shape and is so constructed and arranged that substantially each and every part thereof is utilized in forming the finished carton for cushion shipping and displaying fragile articles, such for example as mirror or glass panelled cosmetic vanity case V shown in Figs. 9 and 10.

The blank 20 when out from a single sheet or from a web forming a roll of corrugated paper board of suitable width, is seen to comprise the following successive wall sections or panels ex tending through the center portion thereof, a rear wall 21 adapted to provide an inner panel which is separated from a rear wall 22 forming an outer panel by spaced fold or score lines 23. A bottom center section 24 is separated from said rear outer wall 22 by fold or score line 25 and adjoins an outer front wall panel 26 separated from said bottom section 24 by fold or score line 271. A top section 28 adjoins said front section 26 and is separated therefrom by the fold or score line 29. Said top section 28 may be formed with integral side flaps 2811 on opposite sides which are separated from said top section 28 by spaced fold or score lines 30 extending at right angles, that is, transverse the fold or score line 29. Extending as a continuation of each of said score lines there is provided a partial through-cut 3! which forms opposite edges of outer front wall panel 28. Each of said cuts 3| also extends to the score lines 30 of flaps 28a which are preferably made slightly shorter than the actual width of the top section 28 as shown in Figs. 1 and 2 so as to fit in the effective assembly structure as clearly shown in Figs. 9 and 10.

Each of the partial through-cut lines 3| connects with a fold or score line 32 which form opposite edges of bottom section 24, and connecting with the score lines 32 are spaced apart partial through-cuts 33, the latter forming successively opposite edges of said outer and inner

rear wall sections

22 and 2|, respectively.

Except for two space sections 34 that extend outwardly from bottom section 24, which form end panels for the carton and are separate from the said bottom section 24 by score lines 32, the remaining portions of blank 25 as yet not described, provide material for making up the interior cushioning structure for the improved carton, there being spaced apart fold or score lines 25a and 21a, which are continuations of

score lines

25 and 21, respectively, and which with score lines 32 bound said section end panels 34.

Each partial through-cut line 33 with parallelly aligned partial through-

cut lines

35 and 35 spaced therefrom provided in the blank 28 beyond said inner and outer rear wall panels 2| and 22, form a pair of bottom side cushions spacer portions 3'! and a pair of end panel cushioning integral members 38 located above, that is, outwardly of said spacer portions 31. A pair of cross-bras ing

portions

39 and 4|! are also provided beyond each of the cushioning members 38 as seen in Figs. 1, 4 and 5.

The bottom side cushion spacer portions 31 because of being proportioned to extend along a greater part of the width of both the inner and outer wall sections 2| and 22 are suificient to form looped structures in the set up assembly, said portions 31 may be provided with central extension tabs 3112 that can be secured together in overlapped relation by suitable fastening means, such as a staple 4|, shown in Figs. 4 and 5. In order to permit forming said cushion spacer portion 31 into a looped structure, spaced transversely extending fold or scor lines 42 are provided at opposite ends thereof and a fold line 311) on each of the tabs 37a facilitates positioning the latter for fastening by staple 4| as can be seen from Figs. 1 and 4.

The pair of end panel cushioning integral membars 38 are each formed into effective position by providing, beside each fold or score line 42, another fold line 43 between line 42 and one end edge 20a of the blank 20, two closely spaced short fold lines 44 extending outwardly beyond each tab 31a, a pair of spaced fold lines 45, and a two fold line 46 spaced similarly to lines 44 between lines 45 and adjacent fold lines 42. All of said

fold lines

42, 43, 44 and 45 are parallell aligned, and an L-shaped slit 46a may be extended along one of said fold lines 46 and across to the other for purposes hereinafter described.

As seen from Figs. 1, 3 and 4, each of said cushioning members 38 is folded on score lines aforementioned to oifstand against the interior side of end panel 34, and is braced by an intermediate triangular shaped structure T formed on fold lines 44, 45 and 45, as shown in Figs. 3 and 4. To retain the said triangular shaped bracing structures T rigid, coupling sections 513 and each formed with

slots

54a and 5|a, respectively, may be used to interlock with slits 46a and the out out portion of members 38 left by tabs 37a. Said

coupling sections

50 and 5| are shown'as a corner portion of the blank 2|] in Fig. 1, and detached in Figs. 7 and 8, respectively. In Figs. 2, 3, 4, and 5,

coupling section

55 and 5| are shown in effective interlockment with the triangular bracing structure T.

Cross bracingportions

39 and 40 which border on opposite longitudinal edges 23d and 230 of blank 20, respectively, are adapted to hinge on fold lines 25a, said portions 39 and 4G terminating in suitable interconnectable ends, as for example, a male terminal 38a and a cooperative slot 4%, respectively, as shown in effective position in Fig. 4.

The improved carton construction above described provides for bottom and end cushioning means up to the

cross bracing portions

39 and 40. Since, for the purposes described, it is often desirable to provide additional cushioning means in the region of the top of th carton, such may be provided as an integral part of blank 23 with a minimum of waste. To this end there is provided between the top section flaps 28a and the edges 2% and 25c of the blank 29, symmetrically disposed partial through-cuts 48 which provide a pair of front cushioning members 49 adapted in the set up assembly to be positioned for cooperating with end cushioning members 38 and top side cushioning spacers 52 which are above, that is, outwardly of said members 43.

Cushioning members 49 each have spaced fold or score lines 53 extending from flaps 23a to the out line 48, and a pair of similarly spaced

fold lines

54a and 54b parallelly aligned therewith but extending from out line 3| to each of the

blank edges

20d and 200. An L-shaped through-cut 55 in each cushion spacer 52 may be provided to connect with said out 48 to form a tongue 55 spaced fold or score lines 51 being provided for bending said tongue 56 out of the normal plane of spacer 52 into an efiective position as shown in Fig. 10. Said tongue 56 can be slitted as at 55a to increase the flexibility of the end thereof.

As seen from Figs. 1, 2, 3, and 4 the remaining symmetrically positioned sections 50 of the blank 20 bound by

score lines

27a, 54a, out line 3| and portions of blank edges 20c and 2501 provide inner front wall panels in the set up carton as shown in Fig. 10.

Where said vanity case V to be packed has protruding ornamentations or draw handles H, suitable cushioning clearancing means may be provided in the cushioning structures, such as formed b providing spaced through-cuts 58 with fold or score lines 59 in members 43 shown in Fig. 1 as extending transversely fold lines 540. and 54b and as shown efiective to clear handle H of the vanity case V in Figs. 9 and 10.

The practical application of the invention will now be apparent. After providing the rectangular shaped corrugated paper board blank 28 formed with all the fold or score lines and through cut lines, some of the latter being only partially cut through so as to retain all portions against accidental detachment as described above and shown in Fig. 1, said blanks 2d are then in most compact shape and size for stacking in storage and shipment before setting up as cartons.

Each blank 20 may be set up as a carton by first detaching

members

53 and 5|, and a member 6| which forms the corner of blank Zil opposite said

members

50 and 5|, adjacent cross member 40.

Next, the remaining portions of the blank 20 on either side of inner and outer rear walls 2! and 22 are folded on score lines 25a to overlie end section panels 34, that is, folded from the position shown in Fig. l to' that shown in Fig. 2. Also the portions of the blank 2:: oneither side of the through-cuts 3| and side flaps 28a of top section 28 are folded over score lines 54a to overlie inner front wall panels 50.

Member 31 is then looped to extend over bottom section 2 5, member 38 folded on

score lines

42, 43, 44, 45 and 46, to provide said construction T, and member 49 folded on

score lines

54a, 54b and 53 as shown in Figs. 3 and 4. The free end portion of said

members

38 and 49 may then be secured in place to end panels 34 by suitable fastening means, such as staples 62, and coupling section 59 and M inserted to retain the said formations T.

The end panels 34 may next be folded from the position shown in Fig. 2 to that shown in Fig. l, that is, on score lines 32 to upstand from the bottom section 24, and cross bracing 352 and 4c interlocked. Tabs Sla of spacer portion 31 may be folded over on score lines 3% and secured in position by a staple M for making the set up structure sufficiently rigid for seating the vanity case V in proper position on edgewise positioned bottom spacer 3'! between end cushioning members 33 and against interlocked cross bracing member 39 and 45.

The inner and outer rear panels 2i and 22 may then be folded on

score lines

23 and 25 so as to form a double upright rear wall cushioning structure with the interlocked cross braces 38 and ii? extending therebetween, the wall section 2i being slitted at $3 on a sufficient spaced apart portion from the end thereof as shown in Figs. 1 and 4 to clear the thickness of the end cushion members 33, as shown in Fig. 10.

With the front section 26 and top section 223 still in flattened out position, the front and top vanity case V is exposed and the carton in this condition may serve as a display receptacle. Now to complete packing the vanity case V, inner panels 69 are folded on score lines 2%, to bring cushion supports formed by members 49 against the front side of the vanity case V and top cushioning spacer 52 may be folded on score line 53a and 56b and the tongue 5% folded on score lines 5'5 so as to bear against portions of the glass top side of the vanity case V, which may be hinged covers of compartments. The tongue 56 will take care of differences in height of said vanity case top side as clearly shown in Figs. 9 and 10.

If a trunnioned mirror M forms. part of the vanity case V as shown in Figs. 9 and 10, the tongues 56 serve to retain the mirror against swinging displacement for the packed position.

Where the vanity case V is provided with protruding drawer handles H, or other ornamentation, the portion of member 49 bound by cut lines 58 and score line 59 may be utilized for clearances as shown in Figs. 9 and 10.

With the top section 28 down-folded on score line 2% and flaps 28a in-folded on score lines Bi a firm relative tight closure is provided which may be sealed in any well understood manner, as for example with adhesive tape, not shown.

It should be noted that the improved carton with the vanity case V packed therein is supported in spaced relation from the top and

bottom wall sections

23 and 24, respectively, by edgewise position spacers 49, 52 and 3?, respectively, which retain said vanity case V against damage and absorb jarring effects to which the carton may be subjected from the top and bottom sides thereof, while the front and rear

upright sections

60, 26, and 2!, 22 provide spaced double wall constructions to form effective abutment cushioning means at the front and rear sides of the carton, and end sections 34 with member 38 forming a spaced double walled cushioning construction for the opposite ends of the vanity case V thus completely guarding the latter from direct impact strains and stresses to which the upright sides of the vanity case V may be subjected.

The above described cushioning structures formed by the interior and exterior of the carton as described above and shown in the drawing also have been found to protect the'packed vanity case V against injury that may be caused by accidental dropping of packed carton on a corner thereof since said cushioning structures served as a bracing construction of sufiicient resiliency so constructed and arranged to absorb such impacts without damaging the fragile contents.

As an alternative means for safely packing the mirror M in the carton when dismounted from the vanity case V, there may be provided an arcuate slit 64 formed with a finger hole 64a to extend along inner rear wall sections 2| inwardly of end edge 26a, of blank 2&3, said slit 64 may be used with member bl having spaced tongues cm for packing the mirror M against said inner wall sections 2'! with said member 6! as a cushioning spacer interposed between the mirror M and the rear of the vanity case V as shown in Fig. 11.

Where the carton is to be used for package shipping of straight sided fragile articles only and the display feature not desired, the above described construction of the carton may be simplified by substituting in portions of the blank 28 in place of

cross bracing portions

39, 40, coupling sections 5s, 5i and member iii, a duplication of top spacer portions 52 with tongue 56 as additional cushioning means as has already been described and shown. In this latter construction it is desirable to apply adhesive tapes in the well understood manner to the upright edges of the carton for retaining the outer rear wall section 22 to the upstanding end panels 34.

It is thus seen that there is provided a construction whereby the several objects of the invention are achieved, and which is Well adapted to meet the conditions of practical use.

As various possible embodiments of the above invention might be made, and as various changes might be made in the embodiment above described, and shown in the drawings, it is to be understood that all matters herein set forth or shown are to be interpreted as illustrated and not in a limiting sense.
