2 Claims.

My invention pertains in general to package constructions and specifically relates to a form of` package having leaved article bearing members.

One of the objects of my invention consists in providing a package construction having a plurality of leaves formed to enclose articles in spaced relationship.

Another object of my invention comprises providing a leaved package construction having a plurality of sheets of coated viscose material joined in leaved bond by an embrittling heat crimping process.

A further object consists in producing a commodity package having a multiplicity of articles individually enclosed in spaced relationship in superimposed sheets.

A further object resides in the provision of a closure arrangement for a leaved package structure in which cover sheets are provided with oppositely closed ends enclosing commoditycontaining package sheets.

These and other objects will be apparent from the following, reference being had to the accompanying drawings in which like reference numerals indicate corresponding parts and in which:

Fig. 1 is a top plan view of a preferred embodiment of the leaved package construction of my invention;

Fig. 2 is a sectional view taken along the line 2--2 of Fig. l;

Fig. 3 is a top plan view of another form of the package construction of my invention;

Fig. 4 is a side view of the representation of Fig. 3;

Fig. 5 is a View showing the structure of Figs. 1 and 2 in a different form provided with a closure arrangement;

Fig. 6 is a transverse sectional view of the representation of Fig. 5 taken along the line 5 6;

Fig. 7 is a view of another form of the package with a closure arrangement; and

Fig. 8 is a side view of the representation of Fig. '7.

My invention is directed to providing a form of package in which a plurality of individual articles can be maintained in individually sealed and spaced relationship in a manner suchithat each article may be used individually as required. Such a package has a great many different uses. For example, in the dispensing of pharmaceutical commodities, a plurality of pills can be individually sealed in the package of my invention 1935, Serial No. 23,362

(Cl. 20G-56) together with a sheet of linstructions as to the proper dosage. In this use, the individual doses can be used as required without disturbing the sealed protection of the other pills or doses and without disturbing or destroying the dosage instruction sheet. This form of package has many advantages over the usual method of packaging such pharmaceutical commodities in boxes and bottles, since the package of my invention is,

from the manufacturing standpoint, of inexpenl0 sive construction and adapted to high speed fabrication, and is, from the consumers standpoint, superior to boxes and bottles since the packaged articles are maintained in sealed and sanitary segregation adapted for individual use. The annoyance attendant the opening and closing of bottles and boxes is also eliminated.

In accordance with the invention, the commodity articles are provided in spaced relationship between sealed layers of transparent regenerated cellulose. These sheets of cellulose material are sealed together in book formation with front and back cover sheets. The cover sheets are preferably provided with indicia such as advertising and instructions as to the use of the packaged commodity. For example, when the packaged commodity comprises pharmaceutical pills and the like, the indicia may include instructions as to the dosage of such pills. According tothe invention, these front and back cover sheets may be joined along their outer vextremities in a closure arrangement. This closure arrangement enables the package to be maintained in a closed condition prior to actual use. That is, the commodity-containing sheets are not exposed to handling or misuse until the package as a whole is ready for use. When the package is ready for use, the closure may he opened by the consumer to permit access to the leaved formation of the package structure.

Referring to the drawings in detail, and particularly to Figs. 1 and 2, there are provided a plu- 'rality of sheets of flexible viscose material I, 2, 3, and 4. The material of these sheets is of what is commercially known as cellophane having a heat treatment coating thereon, although other suitable materials may be' used. The sheets I and 2 together form a multiple article-enclosing package unit. In accordance with the principles of my invention there may be any number of such package units, but for purposes of simplicity I will limit my present disclosure to two such units.

One of these package units will now be considered in more detail. 'I'he sheets 3 and 4 are divided into a multiplicity of adjacent squares by a crimping process which forces the two sheets 3 and 4 together into an interdigitated bond. This forced crimping is done under heat conditions so that the structure of the coated viscose material is changed to become embrittled in the crimped portions, thus forming a very tightly sealed bond and also being more easily susceptible to tearing by the consumer to allow the packaged article to be easily removed.

Referring to Fig. 1 it will be noted that the squares are separated by the vertical areas a and b, and the narrow horizontal area c, in which no crimping occurs. 'I'hese areas form separation lines for the squares and also serve as guide lines for guiding and tearing of the embrittled structure in removing a square by the consumer. Other horizontal lines, such as represented by the area d are also without crimping and lead into the article-containing recess "E between the sheets 3 and 4. These lines represented by d are also tearing guide lines which guide the tearing of the embrittled portions into the package containing recess E. It will be seen that in the center of each of the crimped squares the recess E is provided in circular formation within which the package commodity is placed. For example, a round pill 6 may be placed within the recess E as shown, although several such pills or other forms of articles for individual use can be placed therein.

Between the squares are perforated portions 8, II, and I2 as shown. These perforated portions are cuts extending through the two sheets 3 and 4 and form starting points for tearing each of the individual squares. In other forms of my invention I may also provide these perforated starting portions at the beginning of the guide lines represented at d and in still another form I may omit the guide areas cl" altogether. It will be understood that the package-unit forming sheets I and 2 are similar to the package- unit forming sheets 3 and 4.

Underneath the unit comprising sheets I and 2 there is provided a sheet 9, while above the unit comprising sheets 3 and 4 there is provided a sheet I0. Sheets 9 and I0 are preferably formed of material similar to that of which the sheets I4 are composed and serve as top and bottom covers and indicia sheets; Upon these sheets 9 and III various lindicia may be' placed. On the front sheet the name ofthe manufacturer and various advertising may be provided, while on the bottom sheet 9 instructions for use 'of the packaged commodity maybe placed. This arrangement can be varied, of course, at will, the

sheets 9 and I0 serving as indicia cover sheets in general for any desired purpose..

The uppermost, portions of the sheets' I-4 and the sheets 9 and I D are joined together for an area F which is processed to form a crimped bond similar to the crimping surrounding the recesses E. 'Ihis bond area F is embrittled and due to the thickness ofthe several sheets forms a binding area or backing for the leaved or book construction of the package as a whole.

In use, the consumer may selectively remove the packaged commodity from each square for individual use in accordance with instructions on the indicia cover sheets. Although Vthese individual squares may be torn out for individual use from time to time, the area F is still maintained intact to support the indicia cover sheets and maintain the identity and form of the package.

Fig. 3 represents another form of the leaved package construction of my invention. This construction is similar to the construction of Figs. 1 and 2 except that the unit comprising the sheets I and 2 is staggered with respect to the unit comprising the sheets 3 and 4. 'Ihis staggering is arranged so that the packaged commodity carried by sheets l and- 2 is positioned in the spaces between the packaged commodity carried by the sheets 3 and 4, thus effecting a spatial arrangement in which the packaged articles are arranged in rows in echelon. This spatial arrangement makes it possible to more compactly close the separate package units since the recesses E are staggered with respect to each other and therefore do not abut one above the other. Fig. 4 shows how the package units comprising the sheets I and 2 and the sheets 3 and 4, respectively, can be positioned very closely when the package as a Whole is closed.

In this arrangement shown in Figs. 3 and 4 there are provided sheets 9a and Illa which are cover indicia sheets similar to the sheets 9 and I0. However, the sheets 9a and I 0a are of a width represented by A in' Fig. 3, while the sheets I and 2 are of a width represented by B, and the sheets 3 and 4 are of a width represented by C". It will be seen that the staggered spacing of the package units is equivalent to the spacing between the packaged articles in each respective unit, the cover indicia sheets being wider than either of the package units. The exact relation ship of the staggered arrangement is quite apparent from the representation of Fig. 3. In other respects, the package of Fig'. 3 is similar to the package of Fig. l.

Figs. 5 and 6 represent a structure substantially similar to that depicted in Figs. 1 and 2, except that, in this instance, cover sheets 9b and Ib are integrally contiguous and provided with a central row of perforations I5. It will be noted that the package sheets I and 2 extend into the notch provided by the closure of the sheets9b and IIIb and are held thereby. In this arrangement the commodity-containing sheets I and 2 are not exposed to handling or misuse until the package as a wholeis ready for use. When the consumer desires to begin the use of the package -in removing individual articles, he may open the booklet by severing along the perforations I5, thereby exposing the package-containing leaf between the cover sheets.

The structure shown in Figs. 7 land 8 is similar to that shown in Figs. 3 and 4 except that the cover sheets 9c and Inc are provided with extending portions at the lower side of the package. Similarly, the sheets I4-4 are also provided with -a lower extending portion. 'I'hese lower extending portions are all bonded together under a heat and crimping treatment to provide a bondingarea G similar to bonding area F, A weakened separation line I1 is provided extending across the package immediately above the area G and notches I6 are provided in this area to permit easy separation of the area G from the rest of the package. The area G forms an embrittled inseparable oxidized bond. When the consumer wishes to use the package he may grasp thearea G with his fingers and remove the same by tearing from the notches I6 along a separation line I'I. The package is then in open booklet form with the individual package leaves exposed for use in separation of the individual commodity units. It will be understood of course that the booklet cover sheets shown in Figs. 5-8 may be of various materials aooasea including coated regenerated cellulose and can be provided with indicia in the form of instructions and advertising material similar to the corresponding cover sheets described in connection lwith Figs. 1 4. The closure feature not only avoids unnecessary exposure and mishandllng of the booklet package sheets before they are in active use, but maintains them in the proper structural position to avoid bending and separation of the leaved structure.

The cover sheets 9b and lllb as well as the cover sheets 9c and |00 can also be sealed along the right hand and left hand edges as shown in Figs. 5-8 so as to form completely enclosing envelopes. These seals may also be provided with perforations and weakened areas so that the package will be in book form when these seals are broken.

It will now be apparent that I have provided a novel form of leaved package which offers great utility and convenience in its use. The especial advantages reside particularly in that a great many individually packaged articles can be maintained in a readily accessible yet sealed and sanitary segregated formation with printed in- Y structions or advertising matter in constant association to form a unitary and compact package. Although I have shown modifications and structural details it will be readily apparent that my package construction can be modified or changed by those skilled in the art without departing from the intended scope of my invention. I de not therefore desire to limit myself to the foregoing except as may be pointed out in lthe appended claims.
