My invention comprises a shell I6 having a liner II disposed within the same which forms a container open at the top and indicated in its entirety by the reference numeral iii. ,The container I5 is closed by means of a top l8 and has ajcover l9 overlying said top. These parts will now be described in detail.

The shell I6 is constructed from a blank shown in Fig. 2 which is provided with'two longitudinal scores 2| .and 22 and with two transverse scores 23 and 24 which divide the blank into a bottom 25, lateral walls 26, 21, 28 and 29 and corner flaps 3|. The flaps 3| are separated from the wallsli and 21 by means of cuts 32 which extend in continuation of the scores 2| and 22 and are disposed between the scores 23 and 24 and the edges of the blank. The blank from which the shell I6 is constructed is folded along the various scores to bring the walls thereof in erect position and the flaps 3i within the interior of the shell and adjacent the walls 26 and 21.

For the purpose of erecting the container, 9. form is used which is indicated in its entirety by the reference numeral 33 and which is best shown in Fig. 6. This form may be constructed of wood and has a bottom 34 and side and end walls 35 and 36 connected thereto. These walls are so spaced as to snugly receive the carton when in erected position, whereby the walls and flaps of the carton are held in proper position, as clearly shown in Fig. "I.

The blank from which the liner I1 is constructed is shown in Fig. 3 and is preferably constructed'of a water-proof paper. This blank is provided with longitudinal score 81 and 88 and with transverse scores I9 and 4| which divide the blank into a bottom 42 and lateral walls 48, 44, 48 and 48, and with corner portion 41 disposed between the lateral walls and connected thereto. The blank has extensions 48 and 49 which pro- Ject outwardly from the lateral walls and beyond the comer portions to form flanges. The blank is scored along lines 8| which separate the flanges 48 from the walls 48 and 48. The blank is further formed with double scores 52 which separate the flanges 49 from the walls 48 and 44. In the comer portions 41 of the blank are provided scores 84 which divide said corner portions in foldable corner parts 88 and 88.

In the erection of the liner i1, the wallsthereof are folded inwardly along the scores 91, 98, 39 and 4|, the corner portions are doubled back upon themselves along the scores 84 and the folded parts 88 and 88 folded back upon the walls 49 and 44, as best shown in Fig. '1. The folded structure is then inserted into the shell l8, as indicated in Fig. 1 with the corner portions 41 and with the flaps 8| of the shell l8 disposed between the walls 49 and 44 of the liner l1 and the walls 28 and 21 of the shell I8. The liner is then moved downwardly until the bottom 42 thereof rests upon the bottom 28 of the shell l8. The parts are so proportioned that the liner fits snugly within the shell and so that the flanges 48 and 49 thereof may be folded outwardly upon the exterior of the shell.

The top I8 of the container is constructed from a blank shown in detail in Fig. 4. This blank is provided with longitudinal scores 81 and 58 and with transverse scores 89 and 8| which divide the blank into a top proper 82 and flanges 83 and 84 extending outwardly therefrom. The comers of this blank are entirely removed so that the ends of said flanges lie adjacent one another when the top is folded into erected position. The flanges 84 of the top |8 have cuts 88 therein which extend from the edges of said flanges and up to the scores 88 and 89. The blank further has a diagonal score 88 which extends from the ends of the cuts 88 diagonally across the top proper 82. By means of this construction, a flap 81 is provided which may be swung upwardly along the score 88 to form an inlet into the container or into a position in which thesame serves as a closure for the inlet. Severance of the flanges 84 along the cuts 88 form on the closure 81 flanges 88 which lie in continuation with the flanges 84 when the closure is in closing position.

In assembling the top 18, the top proper is placed upon the upper end of the container l8 and the flanges 88 and 84 thereof folded into a position overlying the flanges 48 and 49 of the liner l1. Likewise, the flanges 89 of the closure 81 are caused to overlie the flanges 48 and 49 of the liner l1. The top H and the closure 81 are temporarily held in position upon the container l5 by means ofa number of spring clips 19 and 1| hingedly connected to the walls 85 and 88 of the form 33 by means of screws 12. These clips have fingers 13 which overlie the top l8 and hold the same in place. When the clips ii are not desired for use, the same may be sprung into the positions shown in Fig. 6. When the same are used to hold the top I8 in place, the clips are ar-v ranged as shown in Fig. 8.

It will be noted that the flanges 82, 84 and 88 are shorter than the flanges 48 and 49, as best shown in Fig. 8. This leaves the marginal portions 18 of the flanges 48 and 49 exposed below the outermost edges of the flanges 89, 84 and 88. The top I8 is attached to the shell l8 by means of two strips of adhesive tape designated by the reference numerals 18 and 11. The strip of adhesive tape 18 is first applied to the flange 84 adjacent one of the cuts 88 and wrapped about the portion of the flange 49 issuing from wall 44, the flange 84 issuing from the top l8 and the portion of the wall 21 lying adjacent the flange 49. This strip of adhesive tape is next wrapped about the corresponding parts along the wall 28 of the shell i8 and then partly about the corresponding parts along the wall 28. Clip 19 is now disengaged and the strip of adhesive tape 11 is now applied to the parts overlying the walls 28, 28 and 29 in the same manner as the strip 18. It will be noted that the strips of adhesive 18 and 11 are of suflicient width to cover the flanges 88, 84 and 88, the marginal portions 18 of the flanges 48 and 49 and to extend well down upon the lateral walls of the shell l8.

Upon removal of the two clips 1|, the closed I container may be removed from'the form 99, whereupon the container is ready for filling. In the filling of the container, the flap or closure 81 is folded back as shown in Fig. 9 and the contents to be filled are discharged into the same through a spout or faucet such as indicated at 19; Afterthe container has been filled, the closure 81 is closed and the flanges 88 thereon caused to overlie the flanges 48 and 49 of the liner l1. The same are then secured in position by a strip of adhesive tape similar to the strips 18 and 11 and in the same manner as employed in the application 'of the strips 18 and 11. This strip has, however, not been shown in the drawings, though it can be readily comprehended that the strip and method of procedure is exactly the same as that employed in securing the top |8 to the container i8.

For the purpose of protecting the top l8, the cover i9 is employed. This cover is constructed from a blank shown in detail in Fig. 5. This blank has two longitudinal scores 9| and 82 and two transverse scores 83 and 84 which divide the blank into a top 88 and lateral walls 88 and 81. The blank from which the cover i9 is constructed is formed with cuts 88 which lie in continuation of the scores 83 and 84 which extend from the scores 8| and 82 to the edges of the blank. These cuts form flaps 89 at the comers of the blank which are adapted to be secured to the adjacent walls 81 by any suitable adhesive. The flaps 89 are preferably secured to the walls 81 at the factory, so that assembly of the same at the location of use becomes unnecessary. In order to minimize the space taken by these covers. the walls 88 thereof are formed with diagonal scores 8| which permit of collapsing the covers into compact flat form. In Fig. 1, the container is shown as having the cover applied thereto. It will be noted that the walls of the cover are sufllciently wide to cover the sealing strips 18 and 11.

In F s. 11 and 12, I have shown a modification of the invention. Inasmuch as the construction of the container shown in these figures is similar to that previously described, the description thereof will not be repeated and the same referonce numerals, to which the digit 1" has been applied, will be used to designate the corresponding parts. In this form of the invention, the flanges I48 and I49 of the liner H1 are made shorter than the flanges I63, I64 and I68, so that marginal portions I15 are left on the flanges of g the top I I8, which marginal portions project below the flanges of the liner. On the marginal portions of all of the flanges of the top is applied an adhesive, such as designated at llll'in Figs. 11 and 12. This adhesive may be of the type which becomes tacky upon the application of moisture thereto or it may be the type which becomes tacky upon heating. In either event, the adhesive is used to attach the closure to the shell of the container and takes the place of the strips of adhesive tape used with the other form of the invention.

The advantages of my invention are manifest. A container constructed in accordance with my invention may be fonned of inexpensive paper construction and has suflicient strength to withstand the pressure produced by the weight of the liquid within the same. With my invention, a water-tight container is provided which does not rely on glued joints for tightness. With my invention, all of the folded parts and corner flaps are disposed between the walls of the liner and shell and thus become completely concealed. The closure used with my container provides ample access for filling and does not increase the cost of the container. When the closure is applied, the container is as strong as if it had no closure. My improved container can be constructed at a nominal expense and is highly practical and serviceable.

Changes in the specific form of my invention, as herein described, may be made within the scope of what is claimed without departing from the spirit of my invention.
