Description
Sept. 1933- s. BERGSTEIN HERMETICALLY SEALED CARTON Filed July 27, 1954 JZe Patented Sept, e, 1938 UNITED STATES 2.128.893 .HERMETICALLY SEALED CARTON Samuel Bergstein, Cincinnati, Ohio, assignor to Edna May Bergsteinand Robert Morris Bergstein, as trustees Application July 27, 1934, Serial No. 137,286
3 Claims. (CL 229-1'l) I My invention relates to cartons made of paper stock, and more especially to such cartons which are adapted to contain liquids, as well as such cartons adapted to contain dry materials, and in 5 any case to be air and liquid tight. In'my Pati ents 1,974,256, Sept. 18, 1934, 1,976,980,0ct. 16, 1934 and 2,074,357, Mar. 23, 1937; I disclose .and claim cartons adapted for these purposes; the improvement in the first-mentioned application being in the making of such cartons so that the crevices at the corners and corner edges of their ends where the flaps are folded together, are effectively hermetically sealed and reinforced so as to sustain the sealed condition; and in 5 my last-mentioned copending application I disclose and claim cartons which not only are sealed at their end edges and corners as just above noted, but I have all of the flaps at one end closed and effectively sealed in the just men- 20 tioned manner, while all of the flaps except one at the other end are likewise closed and sealed, and have a filling and emptying opening which is closed by a main flap that is effectively sealed thereover.
My present invention embodies all of the principles disclosed and claimed in my above copending applications, and is an improvement thereon in respect of certain details of construction of the carton.
30 It is necessary therefore that the container be I of such substantial and closed construction at the flap edges and corners where the flaps fold across each other as to allow no passage of the thin coating while it is being applied, and no 35 breakage of it after it has fully set, under weight or impacts. It must be such as to perfectly support the coating so that it cannot be cracked or loosened, or otherwise impaired.
The methods disclosed in my above noted pat- 40 cuts provide the means for insuring this reliable support of the coating; but in those applications the particular character of the covering of the carton surface was not dwelt upon. My invention is also appropriate for cartons that must be 45 tightly wrapped, such cartons usually containing dry substances; and the provisions forsustaining the wrapper are present in said copending applications. It will, of course, be. understood that my present inventionis not limited to making 50- cartons for liquids, although especially adapted for that; but that the especially strong construction of cartons and the especially effective sealing thereof makes them equally effective for packing dry materials, so as to prevent sitting of such 55 materials from the carton if the materials be of a powdered form, and also to exclude air and moisture, or retain theproperties of the packed material, such as moisture or grease content, or aroma of the materials.
A further object of my invention is to produce a carton answering to the above requirements, and in general constructed as disclosed and claimed in my above mentioned Patent 2,074,357 01 Mar. 23, 1937, in which the filling and emptying opening not only is located close to one corner of the end of the carton, but in which the closing flap which seals this opening is made with parts which are readily separated, one part being local to said opening and being readily detachable to swing open without disturbing the other 1 parts of the flap. The object of this just-mentioned improvement is not only to facilitate opening, but to increase the facility of secure sealing and strong reinforcement at the edges and corners of the end having the opening, including the reinforcement of this sectional flap in its closed and sealed relation to the other end parts of the container.
Other objects will appear in the course of the following description, illustrated by the accompanying drawing, in which- Fig. 1 is a plan view of the blank for my ca ton having the final closing flap adapted to have a section only opened.
Fig. 2 is a perspective view of the top part of my carton, with the section of the flap opened.
In Figs. 1 and 2 is shown a modification of the usual closure flap of the carton. It will be understood that the carton with this modification may be made according to the methods, and with any of the proofing mediums, inside and outside, or either, that have previously been described. The difference between this example of Figs. 1 and 2 and other types. of cartons, is that the flap Hie, which is the final closing flap, is provided with a subsidiary flap local to the filling and emptying opening 2. The flap [6e has a slit Bl from its free edge back toward its hinge, terminating some distance short of the hinge; and from the end of this slit or cut 6|, at right-angles thereto, a line ofperforations 62 extend to the lateral edge of the flap, past the opening 2|}. These perforations 62 are not so pronounced as to weaken the flap so much that it will not act as a unit in the operations of folding it, applying adhesive to it, and closing it, inthe methods previously described. However, when the flap I Be hasbeen closed and sealed, the portion 63 or subsidiary flap, which lies symmetrically to the opening 2|,f that it closes, may be pulled up and be detached from the carton top surface surrounding the opening 2H, and will break and hinge along the line of perforations 82 as seen in Fig. 22. To facilitate grasping it for this operation, this flap 63 preferably has a small tab 64 on its laterally outer edge. This tab 64 is formed by cutting it out of the flap e as seen best in Fig. 1, leaving a recess 65 in the edge of the flap Hie which is of no consequence since this is one of the two flaps first folded in when forming the closed top of the carton, and this recess is covered by flap We as well as by the portion i6f of flap lGe that remains attached when subsidiary flap 83 is opened. An important advantage of this construction-is that the portion 16f remaining intact, preserves the-reinforcement along the edge oi the carton top, and the crevice closures at the corners 38', due to the use of the beads of adhesive or sealing medium as before described for the previous examples. It also makes a neater package when opened. -It will be under stood that this example is applicable to cartons for any of the uses, for oil, or for'milk, or other liquids, or for dry materials, previously mentioned.
It will be understood that latex may be used as the -interior coating of a liquid-holding car ton, instead of lacquer; as latex will efiectively resist liquid penetration, including oils. Even a mineral oils will not be so active on it as to make it unsuited for containers for such oils. Waxes of synthetic resin are obtainable, which are very water and moisture proof. It will be understood that modifications other than those illustrated and described may occur in practice, and that I am not limited to the rather precise disclosure herein, but what I claim as new and desire to secure by Letters Patent is:
1. A paper stock carton having at least one end made up of interlapped flaps se'aled together and so formed as to leave a filling and emptying opening in said end, and having a flap hinged to said end and sealed to said end across said opening by a practically thin film of adhesive sealing material and by an excessive amount of sealing material along adjacent to the hinging of said flap to said end, which excessive amount of sealing material fills the crevices at the corners where the flap bends across the other flaps, said hinged flap having a subsidiary flap attached to it along a line spaced in from the hinge of the flap, and local to said opening, whereby this subsidiary flap may be detached from the surface around the opening and. swung open to uncover the opening, without disturbing the remainder of the flap or the excess adhesive along the hinge and at the corners.
2. A paper carton having end flaps interlapping and formed to leave an emptying opening and having a main flap to seal across the aforementioned flaps and close said opening, the part oi said flap covering said opening formed as an independent flap of rectangular shape having a weakened line of attachment to said main flap whereby said independent flap may be separately detached to uncover said opening.
3. A paper carton having end flaps interlapping and formed to leave an emptying opening and having a main flap to seal across the aforementioned flaps and close said opening, the part of said flap covering said opening formed-as an
