This invention relating as indicated toa vari-' predetermined distance. from the top, which' means that the closure in some" instances will present a neat appearing bag and in others an unsightly bag. It is well known that differentproducts vary considerably in specific gravity especially where such products are hygroscopic and this is likewise true where the products are deliquescent. In providing containers for these various products it is necessary to make such containers sufficiently large to readily hold the lightest product, i. e., the product with least specific gravity, which means that when the product becomes heavy due to atmospheric conditions or peculiarities of manufacture less cubic inches will be required and the container which is large enough for the light product is too large for the heavy pro-duct. It is obvious that unless some means is provided to take care of the vacant space when the container is filled, the appearance will be far from neat and orderly. This in turn means a lack of appeal for paper containers and the like.

It is among the objects of this invention to provide a preformed separate closure member which is placed in position after the contents are received in the bag, the position of the closure member varying with the height of the contents so that at all times, and irrespective of the specific gravity of the contents, a tightly folded neat P ge is obtained.

To the accomplishment of the foregoing and related ends, said invention, then, consists of the 7 modification of the sealing 10o Fig. l is a perspective view showing the top portion cut at a desired distance above the contents. V V

Referring now to the drawing, it will be seen that I have provided a bag generally indicated by the letter B, this bag being shown in Fig. 1 immediately after the same has received its contents. In order to illustrate the invention I have shown a bellows type of bag which is folded along score lines 2 and I, thus bringing the front portion F into abutting relationship with the rear portion R at the upper edges of the bag. It will, of course, be understood that these edges are shown slightly spaced and that such spacing is considerably magnified for purposes of disclosure.

The line 3 approximately indicates the fold over the contents and the line 4 indicates approximately the fold upwardly. After these folds are made a loop of material which may be paper, is thrust downwardly over the top of the bag until the bottom of the loop rests upon the bend 4.- This draws the front and rear portions inwardly and over the contents so that the contents are tightly encased and the whole package presents a neat appearance, except that the sealing loop 5 may extend too far above the bag. If this is the case the loop may be cut as shown in Fig. 7, after which it may be bent downwardly to he as shown in Fig. 8.

If it is deemed preferable to use a strip of paper instead of a closed loop 5 as shown in Figs. 5 to 8, a strip 6 shown in Fig. 9 may be employed. This strip may be either thrust downwardly over the upper edges of the portions R and F or it may be slidably received from the right as viewed in Fig. 11. All of the sealing members 5, 6 and I are adhesively coated and are united to the bag by merely moistening the adhesive and pressing Fig. 11 is of a plan vie the sealing members and the upper edges of the bag together.

In Fig. I have shown a further modification of the sealing member; in this case it constitutes a substantially U-shaped member I which can be thrust downwardly or slidably received from either side of the bag. Figure 12 illustrates the sealing member I in place, the upper portion lying immediately above the top edges of R and. T and the vertical sides being united beyond the vertical folds of the bag at each end.

I have shown a conventional square bottom bellows type bag with score lines I and 2 permitting tucking of the edges but it will, of course,

be understood that I am not to be restricted to this particular type of bag.

From the foregoing it will be noted that I have provided a closure which actually pulls the face and back of the bag together, immediately over the contents and seals such face and back in this position irrespective of the height of the-contents in the bag. r p

Obviously with my closure a bag designed to hold contents of a certain weight will present a very neat appearance regardless ofrthe volume of such contents and furthermore the contents will be securely held in place, thus avoiding breakage which occurs when the contents are rr'eegm' shift having a face and a back, said closure member being united to said face and back and having parts thereof united together, said closure member comprising a preformed loop of material.

2. An article of the character described comprising a bag and a closure member, said bag being partially filled with contents and having a face and a back, said face and back being bent transversely just above said contents and extending inwardly until they abut and thence extending upwardly, said closure member comprising a preformed loop being united to substantially all of such upwardly extending portions.

3. An article of the character described coinprising a bag and a closure member, said bag being partially filled with contents and having a face and a back, said face and back being bent transversely just above said contents and extending inwardly until they abut and thence extending upwardly, said closure member comprising a preformed loop being united to substantially all of such upwardly extending portions and having substantial parts thereof united together.
