SYNTHETIC RESINoUs BAC CONSTRUCTION HAVING FRANCIBLE sEALINC MEANS Filed Aug. 5. 1965 United States Patent O 3,282,493 SYNTHETIC RESINOUS BAG CONSTRUCTION HAVING FRANGIBLE SEALING MEANS Seymour Kamins, Oceanside, and Norman Rosenberg,
Bayside, N.Y., assignors to C-Thru Products, Inc.,
Brooklyn, N.Y., a corporation of New York Filed Aug. 5, 1965, Ser. No. 477,383 3 Claims. (Cl. 229-54) This invention relates generally to the field of synthetic resinous bags, of the type disclosed in Patent No. 3,140,038 granted July 7, 1964 to Leon La Guerre, and more particularly to an improved form thereof incorporating sealing means at the upper portion of the bag independent of the closure effected by the interconnection of the two handle members comprising the handle elements thereof. Devices of this type are generally known in the art, and the invention lies in specific constructional details permitting a wider variety of use, with little, if any complication in the manufacture of the bag.
While bags of the type disclosed in the above mentioned La Guerre patent have been widely used for the packaging of many forms of merchandise, as for example particulated material, or other relatively small objects cannot be conveniently merchandised in bags of this type, unless a separate wrapper is employed. The use of the inner wrapper eliminates the need for the bag itself, and also adds materially to packaging costs.
It is therefore, among the principal objects of the present invention to provide an improved synthetic resinous bag construction in which the mouth of the same is provided with a frangible closure which may be opened after sale of the bag and enclosed merchandise, for the removal of the contents thereof, following which the bag may be employed for carrying other articles exactly as in the case of prior art devices.
Another object of the invention lies in the provision of an improved synthetic resinous bag construction of the class described, and possessed of the above advantage in which the cost of fabrication thereof may be directly comparable to existing prior art devices, thereby penmitting consequent wide sale, distribution and use.
Yet another object of the invention lies in the provision of an improved synthetic resinous bag construction which may be manufactured using existing techniques and sealing machinery, with relatively minor, if any, modification.
Yet another object of the invention lies in the provision of :an improved sealed synthetic resinous bag construction employing a pair of carrying handles, in which the handles may be employed to conveniently fracture a seal disposed adjacent the mouth ofthe bag.
A feature of one of the disclosed embodiments lies in the fact that the frangible closure may be resealed as often as desired employing merely the pressure of the lingers.
These objects and features, as well as other incidental ends and advantages, will more fully appear `in the progress of the following disclosure, and be pointed out in the appended claims.
In the drawing, to which reference will be made in the specification, similar reference characters have been employed to designate corresponding parts throughout the several views.
FIGURE l is a fragmentary view in perspective of an embodiment of the invention, showing the same in closed condition.
FIGURE 2 is a similar fragmentary view in perspective showing certain of the component parts in altered relative position.
FIGURE 3 is a plan view as might be seen from the upper portion of FIGURE 2, and just prior to fracture of the frangible closing sealing the upper portion of the bag.
FIGURE 4 is a plan view corresponding to that seen in FIGURE 3, showing the frangible closure in fractured condition.
FIGURE 5 is a plan View corresponding to that seen in FIGURE 3, but showing an alternate form of the embodiment.
FIGURE 6 is an enlarged fragmentary sectional view as seen from the plane 6 6 in FIGURE 3.
FIGURE 7 is an enlarged fragmentary sectional View as seen from the plane 7-7 in FIGURE 5.
In accordance with the principal form of the embodiment, the device, -generally indicated by the reference character 10, comprises broadly: a handle element 11, and a bag or container element 12.
The handle element 11 includes a rst handle member 14 including a handle portion 15 and an elongated portion 16 having first and second ends 17 and 18, respectively, as best seen in FIGURES 2 to 5, inclusive. The ends 17-18 may be joined to corresponding ends of a second handle member 22. The handle portion 15 is provided with interconnecting means 19 in the form of projections, and .includes an inner surface 20 and an outer surface 21.
A `second handle member 22 is symmetrically formed and positioned with respect to the first handle member 14, and includes a. handle portion 23, and an elongated portion 24 having first and second ends 25 and 26, respectively joined to the ends 17-18 of the first handle member 14. Interconnecting means 27 in the form of mating openings selectively engage the means 19 in well known manner. The second -handle member 20 includes an inner lsurface 28 and an outer surface 29, and in the preferred form is integrally molded with the first handle member 14.
The bag or container element 12is formed of synthetic resinous materials which .are compatible for purposes of sealing with the material employed in the formation of the handle element 11. The element 12 includes first and second router walls 31 and 32 respectively and lirst and ysecond inner walls 33 and 34, respectively. The outer walls 31-32 are similar, each including an lupper fold edge 35, side edges 36 and 37, and a lower edge 38 which is preferably left unsealed during the manufacturing process7 so as to permit the bag to be filled at the time of packaging a piece of merchandise (not shown), following which the edges 38 are lsealed together.
The `inner walls 33-34 are formed integrally from continuous planar material used to form the outer walls 31-32, and are bounded by the above mentioned fold edge 35, a lower perforated edge 40, and side edges 42 and 43 which are integrally sealed with the side edges 36 and 37 respectively. The perforated edge 40 while readily frangible forms a sealed folded edge with respect to the mouth of the ybag element 12, so that with the sealing of the bottom edges 38 merchandise contained within the bag element is completely protected.
Upon sale of the device 10, and enclosed merchandise, when it is desired to remove the same, it is necessary only to grasp the handle members 14 and 22, and move the same apart from each other, as seen in FIGURES 2 and 3, by ydi-sengaging the means 19 and 27. Further movement accompanied by Isubstantial force will bring the vair walls 33 and 34 into co-planar relation, and cause subsequent rupture of the edge 40, as seen in FIGURE 4, the rupture commencing essentially in the central portion of the edge 40 and progressing to the terminal portions thereof.
The device may be again closed by re-engaging the means 19 and 27, thereby permitting the same to be used for carrying various articles after the original merchandise has been removed.
Turning now to the second embodiment of the invention, parts corresponding to those of the principal embodiment have been designated by similar reference characters, with the additional prefix 1. Y
The second embodiment,'generally indicated by refer ence character 47 differs from the principal embodiment in the provision of deformable interlocking means 48 which replaces the perforated edge 40 of the principal form of the embodiment. The means 48 includes an elongated recess forming member 50 which selectively and resiliently engages an elongated enlargement member 51, as seen in FIGURE 7. This construction is most suitably formed by eXtrudin-g the sheet material which forms the -bag element 112 through a die which forms both the member 50 and the member S1, so that subsequent forming and cementing operations are unnecessary. Moving apart the iirst and second handle members 114 and 122 causes disengagement of the members 50 and 51, in the same manner as in the principal embodiment. However, should it be desired to reseal the bag, it is necessary only to flatten the bag to the condition shown in FIGURE l, and apply nger pressure to move the .members `50 and 51 again into mutual engagement.
We Wish it to be understood that We do not consider the invention limited to the precise details of structure shown and set forth in this specification, for obvious modications will occur to those skilled in the art to which the invention pertains.
