Application May 3, 1955, Serial No. 505,697
6 Claims. (Cl. -1311) The present invention relates to a container formed of porous paper material adapted to contain talc or similar powder which is to be disposed of through the pores of the package.
It is an object of the present invention to provide a disposable paper packet containing a small quantity of face powder, talc or other similar finely ground powder which may be dispensed through pores in the walls of the packet. Such a structure has a substantial advantage when used as a powder puff over the conventional powder puff made of fabric, feathers or down; since continued use of such conventional powder puffs is attended with a build up of oils, greases, or organic secretions. The present invention, however, provides a container of paper material which has a relatively smooth outer surface on which foreign material will not accumulate as readily as in the case of the conventional powder puff.
One problem in using paper as an envelope to contain finely ground facial powder or talc, is to provide a paper which will permit the powder to sift through it only when subject to mechanical action as when patted against the skin or other object, and to retain the powder within the envelope at such times as the envelope is not in use.
If a single thickness of paper is used having a close or compact formation, the powder will not readily sift through when the puff is in use.
On the other hand, paper formed from long vegetable fibers having a porous structure, permits powder to sift through continuously, making such a puff quite undesirable to carry.
The present invention overcomes this difliculty by forming a powder puff envelope of a combination of a creped cellulosic web and a paper formation made of long vegetable fibers. These two webs of material are joined together by a thermoplastic material previously adhered to the vegetable fiber web.
The laminated structure of the creped cellulosic web, long vegetable fibers and thermoplastic material is then formed into an envelope by taking several of these laminated sheet structures and securing them together in a desired shape by heat sealing the edges, after previously depositing between the laminated sheet structures a quantity of the desired powder. It should be noted in the sealing process the selection of the creped cellulose having a low density and high porosity is extremely important insofar as it permits the thermoplastic material previously bonded to the long fiber formation to flow entirely through the creped cellulose. This feature thereby permits the heat sealing of the envelope at its periphery by heating the adjacent sheet and subjecting it to the pressures of the heat-sealing equipment until the thermoplastic layers fiow through their respective adjacent crepe cellulose layers to combine with one another, forming a suificiently strong enough heat seal to permanently secure the edges of the bag together.
These and other objects of the present invention will be more clearly understood when considered in connection with the drawings, in which:
Figure l is an enlarged perspective view of a segment of the composite sheet,
Figure 2 is a fragmentary perspective view of the powder puff pack, and
Figure 3 is a sectional view of the present invention.
in order to provide a proper control of the dispensing of finely ground powders, such as talc or other facial powders, through the wall of a paper-formed envelope, it has been found preferable to provide a wall of laminated sheets of paper. Accordingly, the applicant has provided in the present invention an envelope formed of facing walls 1 and 2. These walls may have any desirable shape such as round, square or oblong. But for convenience, they are illustrated in the present invention as being substantially square or rectangular in nature. Between these walls is located a quantity of powder which may be dispensed through either wall 1 or 2. This powder is the usual commercial finely ground facial or talcum powder. The walls 1 and 2 are sealed together along their inner surfaces at their periphery in a manner hereinafter more fully set forth.
Each of these walls comprises an inner layer of a creped cellulosic web 4 having a thickness of P eferably .002 inch to .005 inch. This creped cellulosic web has a high porosity and has a formation of very low density.
The outer surfaces of the walls 1 and 2 are formed of a composite sheet of material 5 comprising an outer web of long vegetable fibers having a porosity in excess of 25 cubic feet per square foot per minute at a pressure drop of .5 inch column of water. This long vegetable fiber web has wet strength properties and is covered on its inner side with a thermoplastic material preferably Vinyon fibers. Vinyon is a thermoplastic fiber material manufactured by the American Viscose Corp. being a copolymer of vinyl chloride and vinyl acetate. This composite sheet of long vegetable fiber and Vinyon fiber has an overall thickness of preferably between .00225 inch to .003 inch. The composite sheet 5 is bonded to the cellulosic web 4 prior to the forming of the envelope by laying the cellulosic web against the thermoplastic side of the long fiber web and applying heat within a range of 325 F. to 370 F. Under this process, a good bond will take place and a laminated web results having an overall thickness in the order of .00425 inch to .008 inch. The envelope is then formed with a quantity of powder enclosed by conventional means after which the periphery of the envelope is sealed by applying heat to it. With sufiicient application of heat and pressure, the Vinyon will flow through the orifices of the creped cellulosic web to bond to the creped cellulosic web of the opposite wall and to the Vinyon of the opposite wall.
It has been found that the combined thickness of the two webs is somewhat critical in nature in properly controlling the flow of powder particles through the walls when subject to a mechanical action such as tapping against the users skin. It has been found that unless such a mechanical action is applied for a short period of time the powder particles will be retained within the crepe folds of the inner cellulosic Web, thus permitting the envelope to be carried in the pocket or purse without danger of the powder sifting through the walls.
It has also been found in the present invention that the single web of cellulosic crepe of low density and high porosity is substantially the only type of web which, when combined with the thermoplastic side of the long fiber paper web will permit a sufficient flow of thermoplastic fibers through its pores when placed in a heat 3 sealing apparatus to permita strong peripheral bond of the walls of the envelope.
Another important consideration in the selection of the webs for the formation of the present invention is the ductibility and softness of the webs used. The Webs of the present invention, when subject tothe pressure applied by the heat sealing elements, permit the fibers of the web to spread and merge with the Vinyon material without completely occluding many of the orifices in the web.
Having now described our invention, we claim:
1. A closed envelope adapted to contain finely ground powder to be dispensed therethrough, comprising inner opposite walls made of a porous cellulosic web, and outer walls made of a composite sheet of porous cellulosie material having one surface bonded to a layer of thermo plastic material, said web being secured to the Fi1f1110- plastic material of the composite sheet, the thermoplastic material at the periphery of the outer walls extending through the porous web and being bonded to the opposite wall of the envelope.
2. A closed envelope as set forth in claim 1 wherein said composite sheet comprises a long fibered wet strength porous cellulose having one surface bonded to.
a layer of a copolymer of vinyl chloride and vinyl acetate.
3. A closed envelope as set forth in claim 1- wherein said cellulosic web has a thickness of between .002 inch and .005 inch, and said composite sheet has a thickness of between .00225 inch and .003 inch with a porosity in excess of twenty-five cubic feet per square foot per minute at a pressure drop of .5 inch column of water.

An envelope for finely ground powder having walls through which said powder may pass by mechanical action comprising inner facing sheets of a porous cellulosic web, and outer composite sheets of a long fibered wet strength porous cellulosic material having one surface bonded to a layer of thermoplastic material, said webs being bonded to the thermoplastic material of said com- References Cited in the file of this patent UNITED STATES PATENTS 1,820,259 Wendel Aug. 25-, 19.31 2,414,833 Osborne Jan. 28, 19,47 2,475,241 Hermanson July 5, 1949 2,521,985 Lang et al Sept. 12, 195.0
