3 Claims.
The present invention relates to cartons, and has for its principal object the provision of means within a carton for maintaining the flap closed ends thereof in a sift proof, sealed condition, at
5 their contacting points.
The carton herein shown is made of paperboard, and as shown, is of standard known construction, and as will be described and shown, in
, detail, later, is provided with a simple means whereby when the carton is ilnally closed and glue-sealed, the normally open crevices of the flap closed ends are sealed against the escape of material from within the carton, and'at the same time the corners of the top and bottom ends or the closure are rendered rupture proof.
'I'he foregoing, and other features of advantage will be apprehended as the herein description proceeds, and it will be obvious that modications may be made in the structure herein, without departing from the spirit hereof or the scope of the appended claims.
In the drawing,
Fig. `l is a layout of the blank of a carton;
Fig. 2 is a fragmentary -perspective view of a.
carton, erected, and in the act of being closed:
Fig. 3 is a view similar to Fig. 2, showing a further stage in closing;
Fig. 4 is a fragmentary perspective view of the carton closed;
Fig. 5 is a section, taken on the line 5-5, Fig.
4, looking in the directionof the arrows;
Fig. 6 is a fragmentary, reduced plan view of a blank layout of modified construction; and Fig. '7 is a fragmentary view of a carton corner of Fig. 6
V when closed.
The present carton, as disclosed in the blank I layoutin Fig. 1, comprises four body forming panels 3, l, 5 and 5 and a glue lap I, these all being defined from one another by score lines e, f, g and The closing flaps 8, 9, III, II and 8', 9'. I0' and ...I I are developed from the ends of the body panels, by associate common score lines I and 2. The naps, while hingedly scored from the body blanks are cut from each other by slits such as a, b, c, and
' dsaid slits being terminated at the common score vlines I and 2.
- After the completion of the blank two crevice and corner sealing paper strips A and B, Fig. v1
' 50 are then glued to the blank by glue strips C-D.
These glue strips are preferably placed on the carton blank and are kept below and above the common score lines I and 2, respectively, as viewed in Fig. 1, such glue strips being shown by the'shaded zones C-D. The glue'strlps C and D,
at panels 4 and 6, are extended beyond the score lines i and 2 to form glue spots iS-'i 5 and I8- I' on the spaced wider flaps S-ii and 9-ii respectively, so that when the sifting strip is applied over the score lines i and 2, about midway of 5 and pressed onto said glue strips in such a manl ner that a portion, of each strip,` unglued, lies over the flaps, and therefore, this portion of the strips is free and unattached, except at the glue spots, as just described.
As viewed in Fig. 1, the upper strip C is glued 20 to the body panels by its lower half 2l and the lower strip D-is glued to the carton by its upper Y half 22.
Then the carton is folded iiat on its score line g, the glue lap 1 is folded on its score line e and 25 is then glued and is affixed on the inner surface of the body panel 6, adjacent the edge i.
In overfolding and attaching the glue lap l to the inner surface of the panel 6 at i, the glue lap carriesrwith it, the extended ends I3I4 of the sifter strips A and B, which are partially glued to the inner face of the glue lap 'I by the extension of the glue strips I and 2 upon thev glue lap. Thus when the glue lap is afxed, the extensions I3 and I4 of the sifting strip are also infolded over and 35 around the corners formed at the glue lap atthe ap junctures. and by overlapping the sifter strip at the corner faces I9 and 20, Figure 1, and as at 25, Fig. 2, the cut corners between flaps 8 and II, and flaps 8' and I I' are reinforced by theoverlap- 40 ping of the ends of the sifter strip.
The carton is shipped in'thls ilat folded and glued condition to the user, who erects the carl ton for filling and sealing.`
In the further showing, in Figs. 2 to 5 inclusive, 45
'only the upper-half of the carton is shown, it being understood, from the showing of the blank of Fig. '1, that both closable ends of the carton may be alike.
In Fig 2, the carton shown erected into rectangular containing position, and having been first closed at its bottom end, and filled, and in the4 act of being closed. l
As the sealing strips C and D, Fig. 1 are free of the aps on their sealing portions Ilvand I'I 65 i respectively, and are by reason of the glue flap ends I8 andv Il thereof being overlapped to the opposite strip ends Il and 20, as at 25. Fig. 2. the
` two strips are made continuous, and form a flexible, inner, foldable liner around the open interior flap surfaces, the sealing strip being thus continuous at the corners and therebetween.
When closing ap il is first over-folded as in Fig. 2, it carries down the adjacent continuous portion of the sealing flap, bending down 'a portion of the sealing flap adjacent closing flaps 8 and I I, angularly, as at 2l-21. Fig. 2.
Similarly when opposite flap l is bent to closing position, as in Fig. 3, it carries down a portion of the sealing flap adjacent to said closure ap 8, bending a portion of said sealing strip adjacent the closing naps l and Ii, angularly. as at 2S and 2s, Fig. 3, leaving the sealing flap portions which are adjacent flaps i and Ii where spot glued, unclosed, with their connecting corners folded at angles at the four corners of the two closed flaps.
Then while in this position, the two closed flaps t and I are glued all' over on their exposed faces, then flap 9 is folded down upon flaps B and III and finally, the flap I i is folded down upon flap 9. and thus the end closing operation is completed, with the portions of the sifting strip on the flaps S-Ii and 9I I' held between two glued faces. the spots IB-IG and Il'-II' and the glue upon the flaps 8 and IIS.
During the closing down of the flaps -8 and I0, the sifting strip. which is unscored, but is of relatively thin paper, tends to buckle at the free marginal portions of the strip adjacent the aps I and I I, and, for this reason the glue spots IB- IB and Il'-|' are utilized to uphold these portions and thereby prevent this buckle and to permit of the angled corners 26, 21, 2l and 20 being readily folded by the closure of the flaps 8 and I0. This arrangement ensures positive action in automatic machine operations ofclosing this type of carton.
Fig. 5 illustrates, in amplified dimensions, the sealed carton at the sectional line of [-5, Fig. 4,- the various superimposed elements of this sift proof closure, and while thelspacings therein indicated are exaggerated for the purpose of east reading, in actual practice the materials of the carton and sift proof seal being flexible, the superimposed coacting closure members are tightly engaged with one another.
From the foregoing it will be seen that all edges and corners protected by the sift proofing strip are held sift tight through the single and multiple overlapping of the sift proof strip, at all points of the folded overlapped flaps thereof.
In Fig. 6, there is shown a portion of a carton blank, similar to Fig. 1, illustrating a further feature of corner reinforcement, of the carton, in which the indices of the various partsv are identical with the showing in Fig. 1. In Fig. 6, the slits b-c, by way of example, are shown as terminating a distance j from the score lines I and 2. The object of this is shown in Fig. '1, wherein, due to the unslitted portions -i, which are 'provided betweenall of the flaps 8, 9, Il and Il, and 8', 9',
I0 and II-, of Fig. 1, the bending down of the flaps on their common score lines tand 2, to close the carton causes the uncut corner sections j to act as compressed webs i, Fig. 7, thus acting to stiifen said corners and to render these corners vsift-proof.
"Thus all of the corners on the carton are doubly reinforced, first by the compressed comer/webs 1. and the diagonal folds 20, 21, 2l and 2l of the sift strip, as well as being doubly sift proofed.
Having thus described my invention what is claimed is:
1. A carton comprising sheet material cut, scored and folded to form a carton including walls; inner and outer naps joining the ends of said walls; adjacent aps, when the sheet is flat, contacting and being separated by slits alined with the `corner scores of the walls; a sift-proof lining adhered continuously along the end margins of the walls and extending against the flaps. and secured to the outer ilaps at a central portion of the flap; said lining at said inner flaps and the end areas of the outer flaps being unsecured; said portion being near enough to the ends of the outer flaps, tohold said lining rmly against the faces of the inner aps when the inner flaps are closed; said slits extending near enough to the walls to avoid interference with flap closing or flap tearing during closing; the slits being remote enough from the walls to form an effective shock-absorbing, lining-protecting continuous reinforcing corner web when the flaps are all closed; side and hinged vedges of the inner ilaps and all edges of -the outer flaps extending substantially to said walls and the entire top face of the inner' aps being covered with adhesive and one outer flap pressed thereon, whereby the lining is adhered between two faces and rendered sift-proof.
