11 Claims. (01. 206-56) 'Thisinvention relates to the package described;

and claimed in my copending application Serial No. 358,377, filed September .26, 1940, and comprises in general-a package for small articles such as tablets, pills, or buttons or powdered or granulated material, or liquid or paste.

In general the package comprises a bag initially sealed across one end and having a tearing flap for removal of the sealed portions to open the bag. The bag also has a fold extending entirely across it inwardly of said sealed end so that after initial opening of the. bag, when the bag is folded it is closed, while when it is unfolded it is open. A cover is connected to the bag and comprises a strip which is folded around and secured to the end of the bag opposite the seal and also has a fold to receive saidfold of the bag. The cover has a closure flap which includes a portion to separably enter said fold of the bag as the cover is folded around the bag so as to hold the bag fold snugly in said fdld of the cover. Thereby the bag is held closed and is stretched and maintained flat between said fold and the point of connection of the bag with the cover so that the bag cannot move or become crumpled in the cover during handling of the package. When the cover is unfolded, said portion of the closure flap is removed from the bag fold and the latter may be unfolded to open the bag.

A person unfamiliar with the structure and operation of the package might tear the bag along the fold to open it, or the bag might accidentally become torn or worn along the fold so as to pen the whole end of the bag and make it practically impossible thereafter to hold the bag within the cover in such a manner as to completely close the bag.

One object of the present invention is to provide a package of this general character wherein the bagshall embody novel and improved features of construction to prevent complete opening of one end of the bag should the bag be torn along the fold by mistake or accident.

With the bag of my copending application, it is also possible, through mistake, to fold the cover around the bag without the cover flaps in proper cooperative relation to the bag fold, and therefore another object of my invention is to'provide a novel and improved cover which will ensure that as the cover is closed around the bag the proper portion of cover shall be brought into the Other objects, advantages and resultsof the invention will be brought out by the following description in conjunction withthe accompanying drawings in which Figure 1 is a perspective view of a package with a fold-closed delivery neck embodying my invention, showing the package unfolded for opening.

Figure 22 is a horizontal sectional view on the line 22-22 of Figure 21, and

Figure 23 is a view similar to Figure 19 show- I ing another form of the invention.

Specifically descri ing the form of the invention shown in Figures 1 to 4 inclusive, the package comprises a bag, envelope or like container A formed of suitable material, preferably thin and flexible sheet or strip material such as paper, "Cellophane, Pliofilm, metallic foil, cloth or the like, especially sheet material which itself is thermoplastic and can' be softened by heat or has a thermoplastic or fusible coating, so that the juxtaposed layers of material can be fused or caused to adhere together by application of heat and pressure, or with glue, to form a seal.

As shown, the bag comprises two opposed layers or sheets a and b of packaging material joined together, as by sealing, under heat and pressure, along one transverse or end margin I and longitudinal or side margins 2, to form a compartment or receptacle'ii for articles or a'commodity for example tablets x to be packaged. The layers a and b at the other end of the bag are sealed or bonded together in a sealing flange 5 to close the compartment and make it amperproof, certain juxtaposed portions of the layers in said flange being unsealed to form a restricted discharge neck 6 leading outwardlyv from. the compartment for removal of the contents thereof.

Preferably the layers in the sealed zones I, 2 and i are also interdigitated or corrugated, both for greater security and for stiffening the edges of the bag.

The sealing flange 5 has a tearing flap 1 extending across said discharge neck as shown in Figure 1, for producing a discharge opening for the compartment 3 when the flap is torn off as shown in Figure 2. More particularly the free marginal end portion of the sealing flange is scored'or weakened along a line- 8 which crosses the discharge neck to facilitate removal of the tearing flap.

The bag is folded transversely through the sealing flange and across said discharge neck between the compartment and the tearing flange, as indicated at 9, so that after the bag has been opened by removal of the tearing flap, it is closable by folding the bag along said fold 9.

The bag is especially adaptable to the packaging and dispensing of small articles, such as tablets, or flowing substances, such as powder, the discharge neck facilitating single delivery of the small articles or pouring of a small stream of flowing substance.

It will be observed that the layers a and b are sealed together inwardly of said fold 9, or in other words, the fold traverses the sealed zone so that should the bag be torn along the fold by mistake or by wear only the relatively small neck 6 will be opened, rather than the whole side of the compartment, and such a small openin can be closed relatively easily.

The bag A is associated with a cover B which is foldable around the bag to enclose and protect it and also to receive printed matter such as advertising media. Preferably the cover is formed of a single strip of material relatively stiffer than the material or which the bag is formed, and is folded at Ill around and secured to the end of the bag opposite the sealing flange as by adhesive or by heat and crimping where the material of which the bag is formed is thermoplastic.

The body portion of the cover strip lies along or is juxtaposed to one side of the bag A, and the cal cover strip has a second fold H to receive the fold 9 of the bag and to form a cover flap C that is hingedly connected at I l to the .body portion of .the cover strip. The flap C is folded at l2 to form two hingedly connected sections I3 and I4, the latter of which is adapted to be arranged in side-by-sidc relation to and beneath th section i3 as the cover is folded about the package. The section 93 is of a size to cover the side of the package opposite the body portion of the cover strip, and the section H is of such size that its edge l5 may separably enter the fold 9 of 1 bag so as to stretch and hold flat the bag between said fold and the pointof connection In of the bag with the cover and at the same time hold the transverse fold 9 of the bag between said end edge l5 and the fold H of the cover when the cover is folded around the bag to enclose it, as most clearly shown in Figure 4 of the drawings.

Suitable means may be provided for holding the closure flap C in this cover-closing position, but as shown the marginal end portion l6 of the cover strip beyond the fold I0 is in spaced relation to the side of the bag A so as to releasably receive the fold I! of the closure flap when the cover is folded around the package, to hold the closure flap against unfolding, as shown in Figures 3 and 4.

With this construction it will be observed that the fold Ill of the cover strip closes and reenforces one end of the bag A, the cover protects the relatively thin and weak material of the bag, the cover flap firmly holds the closure fold 9 of the bag against unfolding, and the section M of the closure flap also serves in the nature of a spring follower and stretches and holds the bag in proper position and against crumpling or displacement in the cover. After the bag has been opened initially by removal of the tearing flap l, the bag can be closed and opened repeatedly by simple folding and unfolding of the cover flap C and the fold 9 of the bag.

The discharge necks may be of different size and located at any desired points in the sealing flange. In Figure 1 the neck is shown as located at one side of the bag and of a size to permit passage of a large tablet therethrough while in Figure 23 the neck is shown at an intermediate point in the width of the flange and of a size to permit single delivery of small pellets.

It may be preferred for som purposes to leave the whole end of the bag initially open and unsealed as indicated at I! in Figure 8; or the whole sealing flange may constitute the tearing flap as indicated at [8 in Figure 12 so that the size of the discharge opening may be varied by tearing of the flap diflerent distances inwardly from the edge of the bag.

The invention also contemplates a bag having a plurality of compartments for articles or substances to be packaged. As shown in Figures 19 and 20 the bag D has two longitudinally extending compartments I9, which may contain the same or diiferent kinds of articles or substances, e. g., tablets 20 and pell ts 2|, The bag structure is otherwise in general the same as that shown in Figures 1 to 4, there being a sealing flange 22 having a discharge neck 23 and an individual tearing flap 24 for each compartment. A fold 25 like the fold 9 of Figure 1 and for the same purpose, extends through th flange 22 and across the discharge necks 23, and a cover of the same structure and operating in the same manner as the cover B of Figure 1, cooperates with the bag D.

tents of the bag, e. g., a tablet, outwardly "between Figure 21 shows a package having two layers of material sealed together in zones including longitudinal zones 29 to form three compartments 26, 21 and.28, and the layers are longitudinally said layers across said zone.

Other modifications in the structure and combination of the bag and cover will occur to those folded along one of said zones 29 between two tures of covers to cooperate with the bag fold forholding the bag closed and in proper relation The structure of this package is skilled in the art as within'the splritand scope of the invention.

Having thus described my invention, what I' claim is:

1. In a package, a bag comprising opposed layers of flexible material .joined together and forming a commodity-receiving compartment having a sealing flange at oneend thereof and -a discharge neck extending into said flange, said to the cover. Instead of the cover B shown in Figures 1 to 4 inclusive. I may utilize a cover such as shown in Figure 5, where the closure includes a flap or section like the section l3, and a second flap or section l3 hingedly connected to having a transverse fold in said flange between 1 said tearing flap and said compartment to close one longitudinal edge of the cover to fold into :0 v

- foldable therearound, said cover having aeciooverlying relation to the .bag beneath the section 8 and with one transverse edge disposed in the bag fold as shown in Figure '7. The section or flap 3| thus performs the same function as the In Figures 8 to 11 inclusive the cover strip has a closure section or flap 32 like the section l3 hinged by a fold 33 to the body of the cover; and

, section ll of Figures 1 to 4, holding the bag 25 closed and against crumpling in the cover.

a second flap or wing 34 is hinged to one longino .tudinal edge of both the body portion and the flap 32. This second flap is foldable inwardly over the bag and also has a fold 35 perpendicular to said longitudinal edge of the cover strip and coincident with the fold 33 to enter the bag fold 1 when the cover is folded around the cover. This provides a stiffer and more secure support of the bag in the cover.

Figures 12 to 15 inclusive show another form of cover wherein the section 36, corresponding 4 to the sections I3, 30 and 3!,has a flap or wing 31 hingedly connected to each of its longitudinal edges (Figure 12) to fold inwardly over the bag (Figure 13) beneath the section 86' and each with a transverse edge disposed within th bag fold as shown in Figure 15. v

If the package is likely to be subjected to rough handling, means is provided to protect or reenforce the edges of th bagand the cover. In

Figures 16 to 18 inclusive I have shown a rec-- 0 tangular reenforcing or protective frame 40 of such size and shape that the bag F may be disposed within and encircled by the frame, the thickness of the frame preferably being approximately equal to the thickness of the bag. One

being crushed by pressure or blows on the pack- 6 age from any direction.

In some cases it may be desirable to initially seal the layers of packaging material together to 0 frame 40 will close the bag along a narrow zone 42 inwardly of the scored line 8, as shown in.Figure 5 or inwardly of the end, of the bag where no tearing flap is used, so that the layers in said narrow zone can be forced apart or separated toopen the bag by simply squeezing or pushing the conflange having a tearing flap extending across said neck for producing a discharge opening for said compartment when said flap is torn, said bag said discharge opening after removal of the tearing flap, and a cover secured to the bag and sure flap to separably enter said transverse fold and hold the fold against unfolding when the cover is folded around the bag, andmeans for releasably holding said closure flap. in coverclosing position. 1 r
