Specification of Letters Patent. Patented DEC. 21, 1920.
-. "Application filed February 26, 1917. Serial No. \150,93i.- Y
To all whom it may concern .1
Be it known that I, CHARLES H. HOWARD, a citizen of the United States, residin at in the county of Essex and tate of ll l assachusetts, have invented an Improvement in Bags, of which the following 'description, in connection with the accompanying drawings, is a specification, like charac- "ters on the drawings representing like parts;
This invention relates to bags, and more particularly to" bags for receiving cement. Paper bags for this purpose must be strong, cheap, and impervious to moisture Black asphaltum and other water-proof adhesives commonly used for rendering paper sheets impervious to moisture while excellentfor waterproofing purposes, lack sufficient strength to hold the seams of the bag together when tensioned by the weight of the cement invthe bag. r
Certain forms of glue or non-waterproof adhesives have adequate strength for the purpose, but if exposed at the seams to moisture exterior of the bag, these adhesives become softened, release their hold, and permit the bag to burst open with consequent loss of cement therefrom. v
On the other hand, if the non-waterproof adhesive is applied to the seams so that it is not exposed to the outside atmosphere, the moisture in the adhesive will beunable to escape through the waterproofed paper of which the bag is made and the adhesive will not dry and harden properly, but will remain soft and ineffectiveto hold the seams together.
If the bag is permitted to remain open,
the moisture in theadhesive in some of the seams may escape through the open end of the bag, but this requires a considerable length of time, and prevents the bags from being quickly and cheaply manufactured and packed in bunches in readiness for use.
Also, if the tops of such bags are secured by a non-waterproof adhesive. either the adhesive is exposed to the outside atmosphere, or the moisture in the adhesive is unable to escape through. the'waterproofed paper of which the bag is made, and consequently the adliesive will-be unable to set properly and secure the parts together.
Various forms; of bags have been conthen these valves are closed; but these valve bags are expensive to manufacture, inconvement to fill, and otherwise objectionable.
One of the objects of the present inventioh is to provide a bag which ihay be quickly and readily made and its seams closed by a strong adhesive which is so applied that it will dry quickly and-set without beingexposed to the outside atmosphere. Another object is to provide a bag in which the moisture in the adhesive for the seams and for closing the topof the bag.

Fig. 7 is a perspective view of the bag inverted and filled with material and in readiabove the bag; and
Fig. 8 isa perspective View of the filledend thereof on top of the cover.
-Referring to the drawing: .The' bag 'ness to receive a cover shown in perspective shown therein comprises a blank 1 (Fig. l) r i which may he died out of suitable sheet material. In the present instance of the invention a composite sheet is employed comprising outer paper lawers- 3. 3 having a layer 5 of black asphaltum or other suitable waterproof materialbetween them. To v strengthen the sheet, reinforcing cords or filaments 7, preferably extending longitudinally and transversely of-the'sheet, may be interposed between the outer paper-layers and embedded in the waterproof layer.
slits -9, 9 may be made in the side edges of the blank conveniently in the course of the operation of dieing out the blank from the sheet material. Preferably these slits are offset and at opposite sides of a'median line 11, 11 extending transversely tof'the blank. 1 r
bends of the margins 15, 15 so that the outer margins will adhere to the inner margins and to the outside portions of the sides adjacent the same.
The edge slits of the blank being offset from the median lineof the blank causes the margins 15, 15 to terminate short of said line,
thereby leaving projections 19, 19 which may be'folded with the outer margins 17, 17 and secured by the adhesive to the outer faces of the sides of the bag. This'is an important feature since the fold at\the bottom of the bag is doubled at the corners, thereby closing the open ends of the fold appearing. in
Fig. 2 and preventing leakage at said corners as will be noted in Fig. 3.
The'wa terproof adhesive at the margins sets quickly and renders the seams thereat waterproof, but as stated, the waterproof adhesive lacks adequate strength to secure the seams when placed in tension by the weight of material in the bag. These seams may be strengthened and secured in the present instance of the invention by a pair of I through the waterproof sides and margins binding strips 21, 21 (Fig. 5), comprising a layer 21 of strong paper or other suitable pervious material coated with a layer 21 of glue or other strong adhesive. These strips are introduced into the bag so-that they over lapthe inner margins 15, l5 and the adjacent portions of the sides of the bag, as will be noted in Fig. 4. v
Themoisture in the glue cannot escape 15, 15 of the bag, but since the binding strips are pervious and not of waterproof material,
the moisture may escape therethrough.
This will leave side margins 17 cover.
In order that the moisture in the binding strips may be quickly absorbed, the bag may be filled with cement or otherabsorbent material concurrently with or immediatefy after applying the binding strips. If means is used for positively introducing the cement into the bag, this means also may be desirably used tb apply the binding strips to the bag, the procedure being such that the strips .are moistened, introduced to and pressed against the inner surfaces of the margins 15, 15 and the adjacent portions of the bag. The bagwith the binding strips applied thereto, and the cement therein is shown in Fig. 7 The cement will quickly absorb the moisture from the glue on the binding strips through the paper of said strips, thereby causing the glue to set quickly and secure the "side margins of the bag together ivith sufficient strength to preventany possibility of the bursting open of the seams of the bag from the weight of the material therein or in the handling of the same.
Previously to the filling of the bag,'the bottom corners of the bag may be gathered as at 23 and be served and secured .by cords 25. There are several advantages in this. It contributes to the desired shape of the bag, increases the strength of said corners. positively binds together the parts of the bag at the corners of the bag' so as to prevent leakage thereat, and provides a pair of handles which may be readily grasped in handling the bag. I
After the bag has been filled as described, the upper open end thereof is closed. To
accomplish this, a cover 27 may be provided,
conveniently died out of sheet material to present a shape conforming to the contour of a horizontal section of the filled bag. This cover comprises a layer of paper 27" or other suitable material having on' the upper face thereof a layer 27 of glue or other strong adhesive. v This'cover is introduced into the bag. on top of the cement or other material therein with the adhesive face of the cover uppermost.
' Then the opposed side portions 29 are folded over toward one, another onto the adhesive face of said cover and become secured thereto. One of these portions may overlap the other and be secured thereto by black asphaltum or other waterproof adhesive.
, Next the opposed upper side portions 31 are folded over toward one another onto the said portions 29 and are secured thereto by black asphaltum or other waterproof adheslve.
Preferably the portions 29, first folded,
should be sufliciently large to cover the Thus, the strong adhesive of the cover. is united to a complete end closure and the strength of the adhesive is available to insure a strong, permanent bottom.
When the bag is completed, it has a Wain the glue or the cover to escape to the outside atmosphere. cover is pervious to moisture, the latter is quickly absorbed by .the cement through the cover and therefore the glue quickly sets and strongly secures the upper side portions '29 to the cover. v
The amount of moisture absorbed from the binding strips and cover is too small to materially affect the cement.
The end of the bag last described forms a more appropriate bottom than top, and the end of the bag-having the served corners forms a more appropriate top than bottom, consequently, the bag may be inverted end forend so that the handles thereof Will be uppermost and accessible for movin the bagfrom place to place, as
desired. referably the bag shouldbe inverted promptly upon completion thereof so that the Weight of the package will bear upon and press thefolded-over end portions 29 and 31 into secure adhesive engagement.
The bag may be quickly and readily made by the method described. Sincethe bag is made and filled concurrently, the two processes are performed with a minimum number of operations and in a minimum amount of time. v The delay and ex pense in separately making, bunching andmarketing the bags are eliminated.
Also, a bag is producedwhich is not only Waterproof throughout, but also is strong and able to withstand the handling thereof and the Weight of the heavy material with which it is filled. The cover not only contributes to ,thetight. closure .of the bottom of the bag, but also serves as a desirable reinforcement therefor.
The bag may be simply. and cheaply made of reinforced paper and adhesives.
Qbeing folded over onto said cover, a non- Waterproof adhesive securing the upper It dispenses withyalves and other expensive devices and materials.
The bag described may not only be used for packaging cement, but obviously may as desired.
alsb be used for packaging other materials,
It Wlll be understood that the invention is not limited to the particular bag de scribed herein, but that extensive deviations may be made therefrom without departing from the spirit and scope of-the appended claims- However, since the" site end of the bag, a Waterproof adhesive securing said margins together, a pair of internal securingstrips extending longitudinally of said margins Within the bag,
' each of said strips having portions super- -.posed on the body of one of said sides and the margin of the other side and secured thereto by a non waterproof adhesive, and
cover adapted to rest on top of the material in the bag, the upper. portion of said sides being folded over and having the internal strips secured to the cover by a non- Waterproof adhesive.
2. A closed Waterproof bag for cement and other materials comprising a bottom, top and opposed sides of Waterproof material, said sides having overlapped margins extending from the bottom toward the top of the bag, a Waterproof adhesive :securing said margins together, and a pair of internal securing strips extending longitudinally of said margins Within the. bag, each of'said stripshaving portions superposed on the body of one of said sides and the 'margin of the other side, and a non Waterproof adhesive for securing said strip to saidbody and margin.
, 3. An air tight bag for cement or other i absorbent material comprising a Waterproof bottom and opposed Waterp r oof sides having overlapped margins, a Water proof adhesive securing said margins together, a pairof internal strips superposed on said margins and adjacent portions of said sides Within the bag, a moisture-containing, non-waterproof adhesive securing said strips to said margins and portions and a-cover adapted to rest on the material in the bag, the upper portions ofsald sides non-Waterproof adhesive of the. strengthening strips and cover being rendered effective by absorption of moisture therefrom by the absorbent material in the airtight bag.
