In my Patent Number 2,099,257, and in my copending application vSerial No. 62,324, I have disclosed containers comprising a multiple wall outer carton, with an inner liner therein, such container being adapted to the reception of contents into the open mouth of the liner, at least at one end of the container. My present invention as herein disclosed constitutes an improvement over these containers, and also is adaptable to other types of lined containers, whether assembled in knocked-down or erect form. By my invention I am enabled to fill contents into the open mouth of a liner in a container, said open mouth being located at one end of the container,

but to display the contents by lifting a side .or a portion of a side of the container after it has been packed and cl0sed,'without disrupting the liner. At the same time I arrange to keep the liner .stretched tightly and smoothly over the opening in the side, so provided, so as to present the contents attractively without exposing the contents, and I have also provided an arrangement whereby the side or portion of the side so raised and folded back into display position, is

ther, as an alternative arrangement I may provide a construction whereby the side so raised is folded around and down under the package, folding therewith also a portionv of another side of the outer carton, the parts so foldedv arranged to be secured under the container to serve as an easel to hold the container in an attractive display position, all without disrupting the liner itself. Further, when it is desired to remove the contents by opening the liner itself, this operay tion is greatly facilitated by my invention `because of the larger area made vavailable-for removal of the contents, than is possible to achieve by removing the contents through the end of the pack- 40 age where the contents have been inserted, and

my invention also provides a reclosure feature, and by my invention I may also provide a' tubular liner wherein the ends of the liner are merely folded in to overlap relation, and not secured, whereby removal through the open side of the outer carton is4 greatly facilitated. These and other objects of my invention will appear in the description and the drawings forming part of this specification, and the scope and nature of the invention will be set forth in the claims which follow, to which reference is hereby made.

In the drawings:

Figure 1 illustrates the form of my preferred carton structure. as a flat blank, prior to the inheld in display position -by the liner itself. Furcorporation of the pre-formed tubular liner therein, the shaded areas indicating the portions that are to be adhered. to the inner liner.

Fig. 2 shows the completed container, with the inner liner therein, in dat or knocked-down form, 5 in which form it may be shipped to the user.

' y Fig. 3 illustrates the container shown in Fig. 2 after ithas been squared up, andclosed at one end, the other end being openand the open mouth of the liner adapted to reception f the contents l0 to be packed therein. l

Fig. 4 shows the finished, packed container, contents havingfbeen inserted and the other end having been closed. In this condition the container is adapted for shipment. 1

Fig. 5 illustrates the abovecontainer with a portion of the side panel having been raised.

Fig. 6 illustrated the container shown in Fig. 5, the lid being folded back to form a display, the t'uck on this lid portion being secured behind the liner as indicated in the drawings, to hold the lid in this folded upright display position.

Fig. 6a is a section taken along line Ba-Ga of Fig. 6.

Fig. 7 illustrates an alternative form of the container illustrated above, vthe lines of severance of the' lid portion being continued around the adjoining side panel as well, and the liner secured in position without adhering the liner to this adjoining side panel, whereby, as shown in 30 the succeeding illustration, the lid panel and the portion of the adjoining panel may be folded away from the container itself, without'disrupting in anymanner the inner liner.

Fig. 8 illustrates the container shown in Figure 'l with the lid portion of the two side panels referred to folded under the container and the .l tuck inserted into a slot provided in the succeeding panel, whereby the entire lid portion, that is the portion that has been lifted away from the two panels, serves as an easel, as illustrated, thereby tilting the container in an attractive tilted position for display purposes.

Fig. 8ais a section along line lla-8a of Fig. 8. 45

Fig. 9 illustrates an alternate construction, wherein the glue seam of the carton is adhered to the outer surface of the panel it overlies, and the flaps articulated to the lid panel -are connected to the lid panel by lines of severance.

Fig. 9a is a plan view, reduced in scale, of the blank for the box ofFig. 9.

Fig. 10 illustrates the 4container shown in Fig. 9 after it has been erected andlled with contents and the ends closed, in the same manner as'de- 55 the lines of severance provided therefor, exposing thereby a complete side, without disrupting the liner itself. v

Fig. 12 illustrates another alternate construction, wherein medial fold lines are provided ontwo opposite panels, by which the carton is folded in fiat or knocked-down form, the inner liner being closed independently at one end of the container. 'I'he lid arrangement is similar to `that shown in Figure 9, except that the lines/of severance in this illustration are located as shown, so that the lid which can be raised is only a portion of one panel, and, not the complete panel itself as illustrated in Fig. 9.

Fig. 13. illustrates a lined carton which has been assembled in erect form, the vcarton itself being made according to my preferred construction as illustrated in Fig. 1,`squared up into erect form and one end closed prior to the introduction of the inner liner. Prior to the introduction of the inner liner within the outer carton, adhesive has been provided to secure. the liner to the carton at the desired surfaces, but provided so as not to interfere with the subsequent raising' of the lid panel on the side.

For the sake of clarity in referring-to the drawings, we will refer to the sides or main body panels of the outer carton, simply as panels and consider that'portion of the sides of the outer carton which is to be raised, as the lid panel Whether this portion adapted to be lifted comprises merely a portion of one of the panels, the entirefpanel, or more than a single panel, as is the case inv Fig, 5. The ap provided on the carton to retain the carton in tubular form. by gluing or otherwise, will be referred to as the glue ap and the end'flaps articulated to the panels for enclosing the end of the container' will be referred to as the closing aps. 'I'he blank shown in Fig. 1 has four vpanels I, 2, 3, and 4, there being transverse lines of severance 5, 5 in panel 4, the portion of this panel between the lines of severance serving as the lid panel. As c an be noted, these lines of severance continue through the glue ap 6, and in this case the lid panel has been provided with suitable lines of cut 'I and fold, to provide a suitable for subsequent folding back` into display position. while if the lid is to servemerely as a means for subsequently opening the container to remove the contents, and not for display purpjoeeathc lines of cut and fold in this lid panel g'lhe-shaded portions 9 indicate the areas of the-inne'r-surfaceof the'carton-which are to be adheredto the'v pre-formed liner.' It will be noted t no "adhesive is provided on the inner suryfacelof the;' lid-panel`s,' or on the inner-surface ofthe portlomof-the glue flap which are articulated tothe' lid'lnel.

FIg. 'shows'the blank illustrated in Fig. 1- the preformed liner has been introduced, 70 and the carton has been folded and secured about the liner. It should be noted that the portion of the glue ap which is articulated to the lid panel is not adhered to the panel I which overlies it, b ut the adjoining portions of the glue flap 75 have been so adhered to said'panel I. thereby serving to hold the carton in tubular form. When the carton has been so folded about the innerliner, `the liner IIIy will be adhered to the inner surfaces of the carton along the shaded areas shown in Fig. 1. In this particular illustration Y the inner liner is a exible pre-formed tube, with the overlapping portions indicated at II, not

adhered to each other.' However, when the inner liner has been so folded and placed within the outer carton, it will retain its tubular condition, but the absence ofadhesion between the overlapped portions of the liner serves to simplify the opening of the liner from the side after the `lid panel has been lifted subsequently. It will be noted from the drawings that the overlapped portion of the liner is placed so as to face upwardly, that is to appear in the opening exposed on theside of the carton when the lid panel has been lifted. In instances where a sealing of the liner is desired, the lengthwise seam will be sealed before introduction of the tube and it may also be desirable to seal one end of the tube forming a fiat bag for securing within the carton. Materials which are transparent and still highly impermeable are vavailable for such` liners.

In this particular illustration the containerr is designed to be closed by inter-folding the ends of the liner and the closing flaps.

Figure 3 illustrates the. container after the carton has been squared up into erected form, and one end so closed. In closing this end,` the closingaps I2 and,l I3 areflrst folded inwardly, serving to fold in a corresponding portion of the open end of the liner with them, and the closing flaps Nos. Il and I5, are folded into overlapping relation. 'I'he flaps may be secured by adhesion, or by locking, or by any oneof a number of wellknown means.

It should be notedfrom the illustration that I prefer to have the end of the liner extending beyond the end of the closing aps which. are the rst mentioned flaps just referred to. In this manner when these flaps are folded in, the liner will lcover the edges or ends of same on the interior of the container, so that no portion of the outer carton itself is in contact with the contents. When the-contents arev of a greasy nature for example, such as doughnuts, this feature is of importancebecause the liner may be made of grease-proof material such as glassine or Cellophane or the like, 'Whereas the outer carton may be cardboard or other material which` .is not grease-resistant, so it is important that introduced and the contents filled, this end may be closed in the same manner as the end just described was closed. The. container is now in the form illustrated in Fig.'4, which form provides a package, the contentsbeingheld'within the inner liner, and the inner liner being adequately secured to the outer carton so that it is held manufacturer of food ship the package,

Fig. 5 shows the with the lid raised. Since the portion of the glue flap which is articulated to the lid panel Products or the like can 'has not been adhesively secured in position. it

from shifting. etc.. and in this condition the package illustrated in 4, but *I glue flap articulated to the lid panel serving as.

is extremely simple to lift this lid. panel, and the linesof severance 5 can either4 be complete cuts througli---the carton itself, or may be lines of perforation or the like. It can also be seen that the lifting of this lid panel in no way` disrupts the inner liner, and the liner is held securely in taut position over the opening, providing a neat and attractive appearance, and providingvv full protection for the contents.

As shown in Fig. 6, this lid panel may be folded back into display position, the portion of the a tuck, this tuck being placed between the liner and the panel 3. It should be noted that the liner has been left unsecured to the upper part of panel 3, to provide clearance space for the tuck in this case. This serves to retain the lid panel folded back into display position, providingv as can readily be seen, an attractive box for the merchant or retailer to place upon the counter, with excellent display value, and at the saine time with the contents protected by the inner liner so as not to be exposed and still receive the full benefit of whatever protective qualities which are provided by the inner liner.

In the modification shown in Figs. 'l and 8, the lines of severance in the lid panel have been con-A tinued into panel 3 as at 5a. In this case the liner is so glued to the carton that the portion of the lid panel formed from the panel 3, is unsecured to the liner, whereby as shown in Fig. 8 the lid panel, comprising parts of b oth panels 4 and 3, can be folded back around under the carton, without disrupting the inner liner in any way. As also illustrated a slot I6 has been provided in panel 2, in which the tuck may be inserted, so that the lid panel which has been folded around and under the package serves as an easel, giving the package a tilt providing an attractive and effective unit on the counter, and here again this has been accomplished without disrupting the inner liner.

In the alternate construction shown in Fig. 9, the entire glue flap 6 has been secured to the panel I, which it overlies, and in this embodi-` ment it should be noted that the glue ap overlies rather than underlies the panel referred to. In this construction as illustrated,.the glue flap has been increased somewhat in width over that actually required to make an effective seam, the reason for this being that the glue seam itself can be confined to a relatively limited area as i1- lustrated at I1, making it simple for the user or dealer tol insert a pencil or other sharp pointed object and rip through this glue seam,v thereby freeing the glue flap from the panel to which it was secured. Thereafter if desired to reclose the lid, the glue ap can then serve as a tuck for the lid panel. In this particular embodiment also the transverse lines of severance I8 serve to articulate the closing flaps to thev lid panel, so

.that after the glue flap has been released by theA seam being broken as just described, the lid panel.

may be raised to expose the complete side of the container. The'liner is secured to the closing flaps along line I9, I 9, in this construction so that it is not released when the entire panel 4 is raised.

In Fig. 10, the container in Fig. 9 is shown with the ends sealed, the contents being therein, I

and Fig. 11 snows this container with the lid raised, as Just described. In Fig. 12 the carton illustrated has intermediate lines of fold 20, in the panels I and 3,

on which the lcarton is folded about the inner adjoining the closed end of the liner by folding in and securing the closing flaps, and after the contents have been introduced the open mouth'of the liner can be sealed independently if desired, and the closing aps at this end folded inwardly, providing a. completed Asquared package in erect form, in which the inner liner is independently sealed. 'Ihe lid panel arrangement in this embodiment is similar to that shown in Fig. 9, except that instead of an entire panel being utilized, the transverse lines' of severance 23 defining the lid panel incorporate only a portion of panel 4, which is an alternate lid arrangement adapted to either the style container shown in Fig. 12, orto the previously described type.

In this form the panel defined by the lines 23 is not adhesively secured to the liner, and the tabs 23a, 23a, are adhesively secured as well as the ap 6, to the outside of the wall I ofthe carton, as shown. l

Inl Fig. 13 the container is formed from a blank as shown in Fig. 1, the blank being folded and glued in tubular form, and thereafter squared up and one end being closed by by the closing ilaps. Thereafter, an erect or squared up tubular liner, which may have one end closed if desired, is introduced into the erect carton, and adhesive provided so as to secure theliner to the carton, ex-

cept for the portions of the carton which forml mouth of the liner, which open liner mouth is exposed between theclosing flaps at one end thereof. Thereafter the liner and the closing flaps at this end are closed, and subsequently the .contents may be displayed by lifting the'lid panel,

which is accomplished without disrupting the liner so that the contents may be displayed without losing in any way the eiectiveness of the protective qualities of the inner liner. Upon lifting the lid panel a large liner area is exposed, and i it is desired to open the liner and remove the contents through this exposed area, it is extremely easy to do so, much simpler than it would be were it necessary to remove the contents through the end of the container where they Were in serted. y

Further, the lid panel provides a very effective closure feature, as for example after being placed on the counter in display positionwith the liner V remaining intact, the lid panel can be again -brought into closing position to protect the liner,

while for example it is carried from the store to the home, and this same reclosure feature is of importance once the liner has been opened, as

'the lid panel can be placed intol closing position 75A securely. as is 'often desired. during the time when the contents are being consumed.I

To achieve the maximum display value, it is obvious that the liner may be made of Oellophane'or other transparent sheets, and of course the liner can also be made of any suitable'ilexible material to providethe desired protective qualities for the contents.

It can b e seen that by my invention, I have l0 providedA means whereby the container can be opened andreclosed if desired, for display purposes, without disrupting the liner and the contents within the liner can be effectively displayed without exposing the contents, and without causing the contents to lose the benets of the protective qualities which may be'inherent in the liner material.

As pointed out, it is immaterial in my invention herein disclosed whether the liner is interfolded with .the aps of the carton or whether the ends of the liner are closed independently of the closing iiaps of the carton. vAs explained in connection with Fig..i 1, I may also if desired, provide a folded pre-formed tubular liner instead of a liner adhered at its tubular -seam if desired, in order to facilitate dispensing of the contents.

It is obvious also that-the. liner could be made of 1 several materials combined, for example a Cellophane face at the portion underlying the lid 80 panel, and other material at the portions adjoining other panels. Such modifications can be made without departing fromthe spirit or scope lof my invention, and having thus described my invention what I claim as new and desire to se- 8l cure by Letters Patent is as follows:
