12 Claims. (Ci. 22g- 4th This invention relates to improvements in folding boxes made from foldable sheet material, such as paperboard, box board, or other foldable sheet stock.

The invention is more particularly directed to the type of boxes which are designed not only for the purpose of protecting the box contents in shipping, handling, storing and seliing, but whose secondary and equally important purpose is to provide a visual display of the packaged merchandise.

The idea of visual packaging is of course not basically novel and several types of boxes are in existence which display the box contents to some extent.

There are firstly the so-called window boxes in which a window is cut into one or several wall panels, so that a portion of the box contents can be inspected without opening of the box. These window boxes either have an open window in which event the removed stock is usually discarded as waste material, or the windows are in the form of hinged flaps, in which event the window may be opened and reclosed.

A second class of boxes for the visual packaging of merchandise are the trays, which, in a sense, are folding boxes which do not entirely enclose contents but usually are open along one side, as the name tray also suggests. A great percentage of the trays presently in commercial use are overwrapped with a sheet of transparent material which, however, affords little mechanical protection for the box contents along the open side of the tray.

Certain types of merchandise lend themselves to visual packaging by overwrapping with a sheet of transparent material. The resultant package cannot properly be called a box since no box blank is used for enclosing the merchandise, but the shape of the overwrap is determined by the shape of the wrapped article itself. In the finished package the packaged article is visible substantially in its entirety, but its appearance is marred Where, due to the creasing of the sheet material, several thicknesses of the sheet material lie on top of one another, and the mechanical protection of the Wrapped article is relatively limited due to the thinness of the wrapping material.

The invention provides an improved form of folding box which entirely surrounds the packaged merchandise, yet provides windows on opposite sides of the box exposing the packaged merchandise to view except for narrow marginal portions along which the merchandise is grasped and held in the box. The windows are not formed by the removal of stock, but by a unique way of assembling the box blank around the merchandise in, what may be termed, a wrap-around manner.

Packages embodying the present invention have an unusually wide adaptability to the packaging of mer chandise of various shapes and forms and provide mechanical protection in a degree not equaled by visiual packages of the above mentioned types.

For example, merchandise of rather unusual shapes, such as decorative bottles, may be packaged in such a way that the shape of the bottle is not only not conllli all

TB, i955 'ice cealed, but emphasized. rthe improved folding box affords mechanical protection of rather unusual order, in that vulnerable points of packaged contents are protected by more than a single thickness of board. Even along the open sides of the package, the contents are protected in such a way that packaged bottles, for example, may be stacked in line with the boxes arranged in windowtowindow relationship without the danger of one bottle making glasstoglass contact with the bottle in the -adjacent box.

By the same token, a packaged bottle may be placed at on a glass top table with the box in such a position that one window is adjacent the glass top. Even in that position the box prevents glass-to-glass contact.

A particular feature of the boxes embodying the present invention is that labels and inscriptions on the box -contents are exposed and may be read, thereby making it unnecessary to provide further labels or printing on the box itself repeating information on the contents.

Merchandise of irregular shape may also be packaged in such a way that an unusual amount of protection is given the merchandise without concealing the merchandise itself and in such a manner that the merchandise may be inspected, even be handled, without opening or destruction of the package. Merchandise of rather odd shapes may be securely packaged in an entirely novel way by grasping the merchandise at portions of great strength, while freely suspending other portions of less strength. For example, collapsible tubes for pastos or liuids may be packaged by virtually suspending the tube by its screw top at one end and supporting the folded over end of theV tube at the other end.

Folding boxes incorporating the present invention also lend themselves to the packaging of merchandise in multiple. For example, a plurality of individual articles, such as rolls of candy, may be packaged by enclosing the individual articles side by side in such a way that engaging flanges of the box grasp the ends of each of the articles.

As will become apparent from the following detailed description, the adaptability of folding boxes embodying the present invention to the packaging of conventional and non-conventional articles is practically unlimited.

Boxes embodying the present invention are readily set up about the box contents by a simple folding and closing operation performed on the box blank. Preferably the box blank is prefolded and preglued and furnished by the box manufacturer or distributor in the form of a double thick, or tubular preglued fiat blank which, by the simple act of folding at the box corner fold lines, assumes final box shape about the packaged article, by proper and automatic formation of flanges, gussets and double thick walls at the proper and intended portions.

The various objects, features and advantages of this invention will appear more fully from the detailed description which follows, acompanied by drawings, showing, for the purpose of illustration, preferred embodiments and applications of the invention. The invention also consists in certain new and original features of construction and combination of elements hereinafter set forth and claimed.

Although the characteristic features of this invention which are believed to be novel will be particularly pointed out in the claims appended hereto, the invention itself, its objects and advantages, and the manner in which it may be carried out may be better understood by referring to the following description taken in connection with the accompanying drawings forming a part of it in which:

In the following description and in the claims various details will be identified by specific names for convenience. The names, however, are intended to be as generic in their application as the art will permit. Corresponding reference characters refer to corresponding parts in the several figures of the drawings.

In the drawings accompanying, and forming part of this specification, certain specific disclosure of the invention is made for the purpose of explanation of broader aspects of the invention, but it is understood that the details may be modified in various respects without departure from the principles of the invention, and that the invention may be applied to other structures than the ones shown.

The blank A shown in Figure l may be cut and scored, in multiple, from rolls or sheets of paperboard, cardboard, or other flexible sheet material. the board need be imprinted or otherwise decoratively finished, since only one side of the blank is exposed to view in the finished box. The blank comprises a series of enclosing wall panels 11, 12, 13 and 14 of substantially Only one side of equal width. The wall panels are articulated to one i* another in end-to-end relationship along box corner fold lines 15, 16 and 17. A tuck panel 18 is articulated to the wall panel 14 along a box corner fold line 19.

Flange panels 20, 21, 22, 23, 24 and 25, 26, 27, 28 and 29 are articulated to opposite edges of the wall panels along side fold lines 30 and 31.

The ange panels are articulated to one another in endto-end relationship along gusset folds 32, 33, 34, 3S and 36, 37, 38 and 39. Each gusset fold comprises two crease lines running from the end of a corner fold line across the ange panel stock. These crease lines are numbered 40, 41; 42, 43; 44, 45; 46, 47; 48, 49; 50, 51; 52, 53; and 54, 55. FoiI reasons which hereinafter will become apparent the crease lines of the gusset folds are preferably so laid out, that they form an angle with respect to the respective corner fold lines running towards them, as is also clearly apparent from the drawings.

The wall panels may be provided with apertures through which portions of the box contents may protrude, one such aperture being shown in the panel 12 at 56.

The ends of the ange panels are` preferably cut at an angle as shown at 57 and 58 to t corner folds in the finished box, as will later appear.

The blank A may be formed into box shape substantially as follows:

Adhesive a is first applied to selected areas of flange panels extending from non-consecutive wall panels, as indicated in the drawing. The blank is then folded along the side fold lines 30 and 31 to fold the liange panels over the respective wall panels to which they are articulated, thereby adhering fiange panels 20, 25; 22, 26; and 24, 29 to panels 11, 13 and 18, respectively. This is conveniently done by passing the blank through a gluing and folding machine, preferably in the direction indicated by the arrow 59 with the tuck panel 18 leading and the wall panel 11 trailing.

The prefolded and preglued blank A is shown in Figure 2 and may be shipped and stored in flat collapsed condition requiring only a minimum of space. The blank is ready forassembly with, or folding about, box contents which, in the illustrated example, is a bottle 69, but obviously could be any other piece or pieces of merchandise occupying substantially the same space as the bottle 60.

The assembly of the box blank about the bottle is most easily cccomplished by first creasing the blank A at the corner told lines and 16 whereby the flange panels 21 and 26 are automatically erected with respect to the top wall panel 12. The bottle may then be inseited, cap 61 first, through the aperture 56 causing the ange panels 21 and 26 to overlie the sides of the bottle. The folding of the box blank along the corner fold lines 15 and 16 causes the gussets at the corners to form by reason of the fact that the flange panels 26, and 22, 27 are adhered to the wall panels 11 and 13. Thus double thickness side walls are formed at 11 and 13. The bottom fiange panels 23 and 28 are erected by folding of the blank at the corner fold lines 17 and 19. This folding operation is preferably performed with the box contents, the bottle 69, in place so that, in effect the blank A is wrapped around the contents.

The upright ange panels positively retain the box contents in the box and, in addition, form a decorative border or frame about the contents. Since the crease lines bordering the gusset folds are not in line, but extend at an angle with respect to, the corner fold lines towards which they run, the upright flange panels have a certain inward bias thereby grasping the bottle 60 snugly instead of bellying outwardly, as they would, if the crease lines were not arranged at an angle.

The flange panels 24 and 29 overlie the tuck panel 18 and form a double thickness tuck ap therewith. This tuck flap is insertable into the space between the endmost Wall panel 11 and its flange panels 26 and 2S. The tuck flap 18, 24, 29 has a snug telescoping fit with the end of the `double thick box wall 11, 20, 25. This telescoping tit serves a double function of first frictionally securely connecting the ends of the box blank together to complete the box assembly as shown in Figures 4 and 5. Secondly, the telescoping t imparts a considerable amount of rigid- L ity and resistance to twisting to the completed box A.

This feature is of particular importance in instances where a plurality of units or pieces of merchandise are packaged in a single box.

The tuck closure is illustrated in section in Figure 5.

' The necessity for cutting back the edges of the box blank at 57 and 58 is easily understood, if it is realized that the tuck fiap 18, 24, 29 meets the end wall 11, 20, 25 with two gussets at the corner fold line 19. The cut back portions 57 and 58 lie adjacent the gusset folds at 47 and 55 which form an angle with the corner fold line 19.

As hereinbefore indicated, boxes embodying the present invention are adaptable to a wide variety of uses, frequently resulting in packages which enclose merchandise in a rather unusual way. Figures 6 to 9 illustrate a tubular blank and box set up from the tubular blank for packaging a collapsible tube for pastes or a fluid by virtually suspending the tube within the box, as contrasted to the conventional method of packaging in which the tube rests in a box on its collapsible wall, which is its weakest portion.

The ilat box blank B is shown in Figure 6 and co-mprises enclosing wall panels 62, 63, 64 and 65 articulated to one another in end-to-end relationship along box corner fold lines 66, 67, 68. The corner fold line 68 is interrupted by a flat U-cut 69 producing a short tongue 70 on the Wall panel 64 resulting in a self opening aperture in the wall panel at the fold line 68, when the blank is folded at the fold line 68.

A tuck panel 71 is articulated to the wall panel 65 along a box corner fold line 72.

Flange panels 73, 74, 75, 76, 77 and '78, 79, 80, 81 and 82 are articulated to opposite edges of the wall panels along side fold lines 83 and 84.

The flange panels are articulated to one another in endto-end relationship along gusset folds 85, 86, 87, 88 and 89, 90, 91 and 92. Each gusset fold comprises two crease lines running from the end of a corner fold line across the ange panel stock. These crease lines are numbered 93, 94; 95, 96; 97, 93; 99, 100; 101, 102; 103, 104; 105, 106; 107, 108. The crease lines of the gusset folds form angles with respect to the corner fold lines towards which they run. The side edges of the ilange panels 74 and 79 are recessed at 109 and 110 for grasping the cap of the collapsible tube as will later appear. The ends of the flange panels 73 and 78 are preferably cut at an angle as shown at 111 and 112 to provide freedom for the gussets 88 and 92 in the assembled box.

A fold-over iiap 113 is articulated to the wall panel 62 at a corner fold line 114 and a tuck tab 115 is articulated to the fold-over flap 113 along a fold line 116.

The flange panels 73, and 77 are of a width suicient to overlap the ange panels 78, and 81, respectively, when the flange panels are folded over the respective wall panels to which they are articulated.

The blank B may be formed into box shape substantially as follows:

Adhesive a is first applied to the marginal areas of the ange panels 73, 75 and 77. The blank is then folded along the side fold lines 83 and 84 to fold the flange panels over the respective Wall panels to which they are articulated and to bring the flange panels 73, 78; 75, 80; and 77, 82 into adhesive engagement. This is conveniently done by passing the blank through a gluing and folding machine, preferably in the direction indicated by an arrow 117 with a tuck panel 71 leading and a tuck tab trailing. The result of the folding and gluing operation is a tubular flat structure B' illustrated in Figure 7. The preglued blank B may be shipped and stored in collapsed flat condition and requires a minimum of space. It is ready for immediate assembly with, or folding about, a tube to be packaged. Obviously other articles adapted to be supported in a similar manner can be packaged in the same way as the tube 118 shown in Figure 8.

The assembly of the box blank is most easily accomplished by first spreading the folded ange panels 74 and 79 sufficiently for insertion of the tube cap 119. The blank is then folded at the corner fold line 66 and 67 causing the ange panels 74 and 79 to assume a slanted position, similar to the sides of a pyramid. The side walls 62, 73, 78 and 74, 75 and 80 automatically form as double thick side walls imparting great rigidity to the box. The flanges 76 and 81 of the bottom panel 65' assume a slanted position and grasp the liar end of the tube between them as shown in Figure 8. The tuck panels 71 with its anges 77 and 82 form a top iiap insertable into the space between the wall panel 62 and its flanges 73 and 78. The fold-over flap 113 is folded over the outside of the bottom 65 and the tuck tab 115V is inserted into the aperture or slit formed by the cut 69. The completed box B is shown in Figures 8 and 9. It securely supports the tube, has a great amount of strength and furnishes an attractive display for the tube permitting printing on the tube to be read, since practically the entire tube is exposed to view.

The blank shown in Figure l0 corresponds to the blank A shown in Figure l, except for the provision of glue laps 120, 121 and 122 on the ange panels 20, 22 and 24, respectively. These glue laps permit gluing of the blank as a tubular structure in the same manner as the blank B of Figure 6. The gluing operation can be performed on a particularly simple gluing and folding machine available in every box makers plant. In distinction, gluing of the blank shown in Figure l requires a so-called double walling machine, also available in most box makers plants, but slightly more complex because of the necessity of applying glue to both rows of flange panels. The blank shown in Figure l0, as well as the blank shown in Figure 6, require application of adhesive to one row of flange panels only.

The blank shown in Figure l() is further modified by addition of a tuck tab closure resembling the closure of the blank B of Figure 6, but requiring lessstock. A shallow U-shaped cut 123 forms a tongue 124 on the wall panel 14 adjacent the corner fold line 19. A tuck tab 125 is cut from the stock of the wall panel 11 and is articulated thereto along a fold line 126. The tab 125 has a further crease 127 and extends slightly beyond the end of the wall panel 11 at 128.

The blank shown in Figure 10 is glued and folded in the same manner as the blank B of Figure 6. Its tuck flap 18, 24, 29 has a telescoping t with a hollow wall 11, 20, 25 and the tuck tab 125 provides a safety latch, so to speak, for the telescoping closure if its extension 128 is inserted through the aperture formed by the U-shaped cut 123. The closure is shown in section in Figure 1l.

The angularity of the crease lines bordering the gusset folds may of course be varied to produce any desired degree of inclination of the box contents engaging flange panels. In the box shown in Figure 4 opposite flange panels 21, 23, and 26, 23 are substantially normal with respect to the top and bottom panels of the box, with a slight inward bias. In the box shown in Figures 8 and 9 the angle between the box contents engaging flange panels and the box walls to which they are articulated is less to suit the shape of the box contents. Considerable latitude exists in the selection of the proper angles for the gusset crease lines. In all instances, however, it will be observed, the gusset crease lines form an angle with respect to the box corner fold lines towards which they run.

Figure 12 illustrates a modification of the blank B of Figure 5, specifically designed for packaging a bottle 129 of mucilage with an elastic, deformable mucilage applicator 13d, an article diicult to package since the applicator must be protected against contact with the box walls to prevent the dispensing slit 131 in the applicator from opening which would cause mucilage to flow out. The box shown in Figure 12 solves the packaging problem in a surprisingly simple and effective way.

The blank of the box 132 corresponds in major respects to blank B of Figure 6. lt is therefore not necessary to describe the blank in detail, but it will suffice to point out certain modifications.

The top panel 163 has an aperture 133 through which the dispensing cap and applicator is Visible. rl`he angles of the crease lines 194 and 195 of the iiange panel 174 are so selected as to provide a somewhat taller pyramidal structure for engaging the bottle top. The anglesv of the crease lines 198 and 199 are selected to provide for less taper of the flange panel 176 than in the box shown in Figure S. It is thus seen that changes of a few dimensions and angles adapt the basic box for the packaging of an entirely different type of merchandise.

The box shown in Figure 13 may be considered a modification of the box shown in Figure 4. The box structure includes auxiliary crease lines 134 and 135 in the side walls for producing a snug fit between the box contents represented by a decorative bottle 136 and the side wall panels of the box.

The invention thus provides a novel and highly adaptable type of package which may be constructed from a surprisingly small amount of board, is highly versatile and serves not only as a protective enclosure, but also as a decorative display box. The illustrated examples show certain uses of the novel and improved box, but it is apparent that the shapes, sizes and types of merchandise which may be packaged in the novel box are numerous and that the basic structure hereinbefore described may be adapted to other forms of merchandise by simple changes. For this reason various modifications, additions, omissions, substitutions and other changes may be made without departing from the spirit or essence of this invention.
