Application fil ed December 20, 1915. Serial No. 67,758.

To all whom it may concern.

Be it known that 1,,EIJE W..LABOMBARDE, of Nashua, in the count of Hillsborough and State of New Hamps ire, have invented -such as oysters and pickles, and has particular reference to the manufacture of such vessels from fiat blanks.

One of the objects of my invention'is'to provide liquid containers economically made from flat blanks so formed, folded and treated as to be capable of retaining liquid, without leaking, for such length of time as to render the containers and delivery of milk.

Another obj ect' is to rovide vessels of this character which may e laid on their sides without leaking. Y Y

Another object is to provide such vessels with clips or clasps which not only hold; the tops closed but may be utilized as handles for carrying the vessels.

Another object is to provide suchv vessels practical for the sale which may be filled with definite quantities of liquid without requiring previous measur ing, and which will enable the customer to see at a glance, when he opens the top, if he is etting what he pays for.

0 these ends, the invention consists in the improvements which I shall now proceed to describe and claim.

Of the accompanying drawings:

Figures 1 and 2 are plan views of one form of paper blank suitable for making the liquid container or vessel, said figures illustrating opposite surfaces of the blank and being shaded to illustrate what portions have been treated with water-proofing material, such as parafiin.

Fig. 3 is a perspectiveyiew of the blank folded up to container form, and the top partly open. Fig. 4 is a perspective View of the container or vessel closed.

Fig. 5 represents a section on line 5-5 of Fi 4.

Fig. 6 represents a section at a right angle to Fig. 5.

Fig. 7 is a section on line 7-7 of Fig. 4. Fig. 8 is a detail view illustrating a different folding of the top.

Fig. 9 is a plan view of a slightly different shape of blank.

Similar reference characters indicate similar parts or features in all of the views.

Referring first to Figs 1 and 2, the dotted lines indicate creasing to facilitate the fold-j ing of the blank to the condition illustrated in Figs. 3, 4, 5 and 6. The said dottedlines divide the blank into portions orsections 12, 13, 14, of which the member 13 forms the bottom and the members 12 and 14 form two. of the sides when folded and stood up as indicated in Fig. 4. The wings 15,16,

17, 18,19 and 20, when the blank is folded .up, overlap, and are secured together by asuitable adhesive, the operation being by a suitablemachine which may be of the gen-' eralty e explained in my I 1,161,22 granted November 23', 1915.

'will state here, however, that for the purposes of this present vessel,.I prefer that the small wings 19, 20, shall be inside, as-

. shown in Figs. 5 and 6 instead of between.

the large side wings as in the boxes folded, by the machine of that patent.

U. S. Patent Extending from the sections Maud 12 are I flaps 21, 22 respectively, which are to form members of the top closure of the vessel, one of said flaps, as the flap 22," having a narrow tucking flap 23; and extending from the wings 15, 16 are flaps 24, 25, respectively, which also form members of the top closure. The upper ends of wings 17, 18, are connected to flap 22, by triangular foldable sections 26, 27, which are creased-as'indicated by dotted lines in Figs. land 2, to

enable them to be folded as hereinafterdescribed. The wings 17, 18, have small holes; 28 near their junction with the sections 26, 27, for a purpose to be described.

. In carrying out .my invention, the paper is. coated with .a suitable water-proofing material such as parafiin, preferably before it is folded to form a vessel or container, although -some features of my invention are e ually' as useful if the water-proofing is e ected after the blank is folded. Figs. 1 and 2 especially illustrate how the blank will be water-proofed before. it is folded. The parafiin or equivalent is applied to both surfaces of the blank,'but not to the entire area of either surface. That is, the portions which, when the blank is folded up, are to overlap and be secured together by glue, are left uncoated. The shading in Figs. 1 and 2 is to indicate the water-proofedportions and the un-shaded areas are those which are left un-coated. Glue will not adhere to parallined paper, and therefore, in carrying out my invention, I prefer to leave nil-paraffined those areas to which glue isto be applied in order to keep the vessel in the form shown in Figs. 4 and 6 when the blank has been converted to that form. When the hesively secured tbgether. Thus it will be seen that two side walls of the vessel (12, 14)

r are each of a single thickness, with both surfaces and the crease lines fully coated, while the other two side walls of the vessel comprise the overlapping wings 15,,16, 17, 18, 19 and 20 (seeFig. 6) which have uncoated areas glued together but also have coated areas that effectually prevent the 'paper from being affected by contained liquid. By comparing Figs. 1 and 2, it will be seen that the water-proof coating effectuall protects all creased lines.

t is to be understood that in applying the water-proofing materialto the blank itis done in such manner as not to penetrate entirely through the paper. If it did, the glue would not cause the overlapping portions to adhere. The said material is applied only as a coating, being allowed to cool and set before getting into the paper to any such ex tent as to present any of the material atthose surfaces which must be left un-treated to hold the glue. M

It 1s, of course, essential that if-the vessel" is to contain liquid for any length of time,

especially if liable to be laid on one side, it can be effectually sealed by a closure. When the blank has been folded as described, it' will besubstantially as illustrated in Fig. 3., but the flaps 24, 25, will be standing substantially upright. After it is filled, the said flaps are laid down to the plane of the top of'the side walls. Said aps are of such size and proportion that they meet (see Fig. 6) and practically close the top of the vessel.

When the receptacle is converted from the condition shown in Fig. 3 toward and to the condition shown in Fig. 6, the first closing movement of the flap 22 bows the sections 26, 27 outwardly until each is nearly doubled. Then as the lip 23 is tucked in as described, the folding of flap 22 down fiat first completely doubles the sections 26, 27 and then draws them first to upright position and then somewhat inward toward each other. As the flap 21 has been, in the mean time, folded on top of flap 22, the said folded triangular sections will readily retain somewhat the position indicated in Fig. 6, even Without the employment of any clip to hold them there.

The reverse of this operation opens the vessel. The flap 21 aids in properly folding .the triangular sections toward each other because it afurnishes two edgesover WhlCh are the outer-most ones of the double-thick walls, no leakage can occur through said holes. To facilitate the attachment, or re moval,'of the clip, and insure its remaining in position, it is preferably bent at one or more intermediate points 30, to form a spring or springs whereby the clip is reslliently extensible. The clip not only holds the triangular folds down to keep the vessel sealed, but it may be used as a handle. It will now be understood that the blank as shown in Figs. 1, 2 and 9, comprises a strip of paper scored to rovide a bottom section 13, and two side-wa 1 sections 12, 14, each of which has a pair of wings (19 and 20, or 15 and 16, or 17 and 18) extending laterally therefrom. The Wings 15, 16, of the side wall section 14 have flaps 24, 25, which form members of the top closure (see Figs. 3 and 6), the Wings 19, 20, reinforce the bottom and aid in preventin bottom leakage through the overlapped jo1nts, the flaps 21, 22, at the ends of the. strip, coact with the flaps 24, 25 in making a liquid-tight top closure, and the triangular sections 26, 27, which connect the wings 17 18, with the flap 22 will, when folded toward each other across the several overlapped flaps 21, 22,

24, 25, retain those flaps in relative positions to effectually seal the triple-thick top of the receptacle. As indicated in Fig. 8, the triangular por-- tions may be double folded, and a clip 29 with hooked ends, engaged therewith, the double folding providing a strong connection for the hooked ends of the clip, which thus engages several thicknesses of the pa er, but without permitting leakage.

en my improved receptacle or containers are to be used for the sale and delivery of milk or other liquids that are to be furnished in measured quantities it is desirable to rovide them with scale marks 01' capacity indicators for several reasons especially to enable accurate quantities of the liquid to be poured in without previous use of a separate --'-measuring vessel, and still avoid liability of so filling a receptacle as to result in bursting if the liquid freezes. Supposing that the container is to hold a quart of milk, the blank will then a made of such size that when folded up as shown in Figs. 3 and 4, its capacity will be somewhat greater than a quart so that it may contain a quart and still provide a space above the milk to avoid liability of the paper being burst 0 en at any point if the contents should reeze. The blank is providedwith a capacity'indicator which may consist of a printed line a on se'ction 12-or section 14,

or on each of them, on such portion thereof that when the blank is folded up, the line or lines will be just below the top of the be relied uponto measure the milk or other ders the paper sufficiently translucent so that the line or lines a show through and can be seen from the inside when the top liquid accurately. While the mark might be made by creasing the pa er, I prefer to'print it and, of course, be ore paraffining the blank. Printing does not in theleast weaken the paper, and'a printed line is more readily seen than a creasedline. The lines are rinted onlyon those surfaces of the blanhs which areoutside when folded up. If printed on theiinside, the vessel would be less sanitar the milk. he parafiining of the blank renof the vessel is open, thus enabling the dealer to fill the vessel with the required amount of milk, without previous measuring in another vessel, and enabling him to determine how much is to be left at the top' toprevent bursting from freezing. It also enables the purchaser, when he opens the to contam liquid without leaking, said blank having portions adapted to be overlapped vessel, to compare the level of the'milk with the scale mark or marks and know if he is getting the full unit of measure which. he

pays for. T e paraflining, it is to .be understood, does not render the paper sufficiently translucent to enable the height-or level of the contents to be seen fromthe outside;

hence the proper hei ht or level is ascertained by comp'aring t e level of the liquld,

while the top of the vessel is'open, with thev indication or shadow of the mark transmitted through from the outside. The mark or marks are placed on those portions of the blank which, when folded up, constitute.

sides or walls of single thickness, in order.

to be visible through as described. If placed on any of the portions 15, 16, 17 or 18, they would not serve the purposes described unless in very strong light, because those portions are overlapped and hence the 'walls there are of double thickness. Of course the mark a may have, adjacent to it, a suitable printed legend, such as 1 pint or 1 quart.

So far as concerns some features of my invention, I do not limit myself to paraffinr as the ink might contaminate ing the blanks, leaving un-coated those porduction however is more expensivein time and machlnery employed, than the one which I have hereinbefore described.

A particular advantage possessed b my improved vessel or liquid container is t at it may be laid on one side-(especially if that side formed by the wall 12 is underneath) with little or no liability of leaking.- This enables the vessels whichare tapering in form, to be so laid or packed in a crate in alternating arrangement, that there will be nowaste space between them. I do not limit myself to having the tuckmg flap 28 extend from section 22. It

may extend from section 21 as indicated in- F'lg. 9. Such formation however, necessi-r tates a different order of foldin down the members of the top closure. If t e vessel is formed from a' blank having the shape shown in Fig. 9, the flap 21 must be folded onto flaps 24, 25,- before the flap 22 is folded down.

I also do not limit myself to so treating the blanks as to leave the un-coated areas as .large as indicated in Figs. 1 and 2. It is only essential that such areas shall be of a size to permit the use of an adhesive on sufficient space to cause the overlapping side members to be properl secured together.

Having now descri ed my invention, I claim 1. A paper blank for making a receptacle and. adhesively secured. together when the blank is converted to receptacle form, the blank being coated with water-proof mater1al, excepting one face of those portions which are to contact with each other and creased lines to facilitate fol ing the blan to form a liquid receptacle, said blank being coated wlth water-proof material, surface areas of the wings being left uncoated to enable those portions-to be adhesively se-.

cured together when overla ped, the surface areas opposite those which are uncoat-y ed being coated with water proof mate-- rial, the waterpro0f coating including all creased lines.
