R\\\; IIIIIIIIIIIIIIIIIIIIII 25 7 I 5'- i I INVENTOR. @Zbfkf @R AA 2,746,502 BAG WITH INTEGRAL CLOSING MEANS Alberto Camprubi Graell, Sabadell, Spain Application February 15, 1954, Serial No. 410,255

3 Claims; (01. 150-3 The invention is characterized in that it comprises at least a larnellar element made of flexible material, the edges of said element being joined to one another so that they form a bag having two faced walls, said walls being provided with respective edges adapted to be joined with one another to close the bag, said walls further having on their facing surfaces andclose to the edges thereof respective means 'arranged lengthwise of said edges, elastically engageable with one another to constitutea closure impervious'to dust and moisture.

Other and further objects of the invention will be apparent from the following detailed discussion of some preferred embodiments of the invention taken together with the accompanying drawings in which Figure 1 is a perspective view, partially cut away, of the portion adjacent to the opening of a bag provided with closing means according to the invention;

Figure 2 is a cross-section taken on the line 2-2 of Figure 1, showing the formation of the opening for starting the separation of the closing edges;

Figure 3 is a view similar to that of the Figure 2, the closing means being coupled; I

' Figure 4 is a perspective view of a portion of a continuous sheet applicable for the manufacture of the bag in the particular disclosure;

. The sheet 10 is cut to such measurements and outlines that it shows two parallel edges 11, 12 and is bent following an intermediate line shown at 13 in the Figures 1 and 4, at the same distance from each said edge and parallel to the same.

The two adjacent edges 14, 15 and 16, 17 which result between the edges 11, 12 and the line 13 at each side of the bag, within the new two-ply outline obtained, are joined to one another, within the said pairs, by means of a Welded seam 18 extending from the line 13 to the adjacent free edges 11, 12.

When utilizing other methods for bonding the edges 14, 15 and 16, 17, the specific kind of union thus resulting may be substituted for the welded seam without this meaning a departure from the scope of the invention.

Preferably the sheet 10 is obtained by transversely cutting an endless strip 19, Figure 4, made of the already described material, which longitudinal edges 20, 21, are provided with means 22, 23 engageable with one another to form a closure impervious to dust and moisture, which are described hereafter. These longitudinal edges are those selected in the sheets 10 cut from said endless strip to constitute the adjacent free edges 11, 12'ofthe bag. I

The endless strip 19 is obtained according to any conventional laminating process, provision being made in the laminating rollers or extruding dies of spaces suitable for providing the reinforced edges 29, 21, either direct in their final shape or the edges 20, 21 obtained in an intermediate state may be subjected to further drawing extrusion or lamination stages with the purpose of obtaining the respective final cross-sections, eventually with simultaneous application of heat according to one of the well known methods. The reinforced edges 2%, 21 may also be provided by bonding to the plain edges of a conventional endless strip 24, Figure 5, complementary laminations 25, 26 which are integrated to the general section of the sheet, either through one or more laminating extruding, Welding or cementing steps, or through combinations of such operations.

In the Figure 5, the edge 21 is intended to constitute the male element of the engageable means and it is obtained by superimposing the narrow laminated element 25 on the edge of the sheet 24. The laminated element 25 is bonded to the sheet by any of the previously indi cated methods and has for its object to provide an increased cross-section over which the circular section pro- Figures 5 and 6 are respective cross-sections through the male edge ofthe continuous sheet in two alternative embodiments thereof;

Figure 7 is a section of the closure of the bag with a form of holding means to hold the bag closed.

Although the'drawings show the diverse parts of the bag as being provided with exaggeratedthicknesses for the purpose of making the showing more easy, it must be understood that. the scope of the invention is not restricted by such dimensional features and in practice the invention may be developed with the thicknesses of the materials commonly found in the market.

The bag 10 is formed of a sheet of lamellar material of an enough flexible nature such as to allow the bending paper and textiles.

file 26 forming the coupling means is fastened in a similar manner. v t

In the Figure 6, the male element is obtained by bending a marginal portion 27 of the sheet 24, securing the portion 27 to the sheet body and coupling onto the increased section thus obtained the complementary profile 26. The bonding of these elements in order to constitute a single profile may also be carried into practice by any of the methodsset forth, which will be well known to any expert in the manufacture of plastics.

In the cases wherein the material forming the bag is of a fibrous nature such as paper or textiles, the reinforced edges 20, 21 may be provided by coupling profiles like those already described to the edges of the corresponding sheets, eventually after forming the edges of the fibrous material with means intended to facilitate the bonding thereof to the plastic, for example holes or other surface deformities.

In either case the edge 20 constitutes a female coupling means engageable with the male element 21( The cross-section of the element 21 comprises a re inforced section 28, Figures 1, 4, 7, of substantially rectangular shape, coupled by one smaller side thereof to the laminar body 19 which constitutes the bag. The greater side of the reinforced section 28 which faces to Patented May 22, 1956 the edge 20 when the ensemble is in operative position is formed with a circular salient portion 29 having a diameter greater than the width of its zone of union withthe part 28..

The cross section of the female element 20. comprises. a rectangular section 30 of similar arrangement. to that of. the element 21.. The. greater side of. this rectangular section which faces the male element previously described, when the ensemble is in operative'position, isv formed with a. recessed section substantially corresponding;

with the section 290i the male element.

, In this manner, the female elementZt) is formed with: a longitudinal: groove 22 facing, to the male element. The width at the opening of this groove is less. than the width of the groove at intermediate depths of the same. The male. element 2Ihas alongitudinal rib 23 locatedin engaging arrangement with. said. groove and having a diameter greater than. the; section wherein. the rib' joins. with the male element 21.-

As the material. forming the elements described is. flexible, it is obvious that the same: may be coupled: with one another by urging the rib 2.3 into the groove 22.. Then the elements remain coupled with one another until a. great enough contrary action. forces the separationthereof for opening the bag.

it may be seen. that. any cross-section of the elements 22, 23 bearing the feature of having, the rib 23 a restricted width at the section joining. the reinforced edge 21 and, the groove 22 a mouth. narrower. than their. intermediate portions is well suited for utilization with the present invention althoughthey may have av geometrical shape substantially difiering from that described.

gagement of the elements 22, 23, when the bag results sealed.

Opening the bag is perfofrmed from the end provided with the cavity 34, as already explained.

In the cases wherein no special means for closing the bag is provided, I prefer to use a simple securing means consisting in a flexible strip 44, Figure 7, cemented or otherwise secured to one edge 20, 21. The strip 44 is placed: initially in straight position extending upwardly from the edge of the bag as shown in dotted lines. Once the bag is closed the strip 44' is bent over the edges 20, 21 and again at the opposite side of said edges as better shown by full lines in the Figure 7'.

It may be also advisableto secure a string 45, Figures 1 and 7, at the one end of the closure, for example by bonding one end of the string with the welded portions which constitute the welded seam 18. This string extends loosely within the bag. and is made to protrude to I 20 and 21.

In the same manner, there may be provided inthe end of said reinforced edges, which cut extends from the inner face or greater side of the cross section of the edge towards the outer face or opposite greater side of the same. In the reinforced edge 20, this cut 32 intersects completely the section of. the groove 22, starting at an intermediate point near to-one end of the edge and towards such end. Inthe reinforced edge 21,. the. cut 33 extends until completely intersecting the rib 23, starting and terminating at the same point according tothe lengthof the edge as the cut in the'edge 20.

The material comprised between these cuts has been removed so that between the two edges 20, 21 a cavity 34 is formed, shown in the Figures 2 and 3, which communicates the outside with the inside of the bag through the junction of the closure.

In the Figure 2 the. cavity is disclosed in. the" opened position" of theclosing, means.

In the Figure 3 the cavity is showrrv in the closed position of the closed means.

These cuts are made long enough so that the cavity 34 is present either with the closing means in their en gaged position as. shown in- Figure 3, sothat one .can

insert a nail or a suitable tool into the cavity and to open the closure by moving the tool. or nail. lengthwise of the edges 2d,. 21: as indicated by the arrow 35. In this manner the closure maybe opened in a similar man nor as a conventional slide fastener is operated.

As illustrated in the figures and described in the foregoing specification, the bag may be closed by hand by holding the bag with two fingers of one hand at; the point 36 and grasping with two fingers of the other hand the edges 20, 21 with a given pressure applied as the arrows 37 at a point adjacent and placed inwardly of the edges,

for example at the position shown by the arrows .37,

It is obvious, of course, that various modifications such as shape and size, as. well as suitable materials can be utilized in the present invention without departing from the scope thereof as. defined in the appended claims.
