The present invention relates to containers and more particularly to containers having a pouring outlet or a sifter top for removing the contents.

Various types of products,I for example face powder, bath salts, et cetera, require a container having an outlet from which the contents may be readily poured or sifted from time to time and which may be sealed or closed during the interims between use. Generally, such containers have heretofore been made of metal or glass, sealed with metal or molded closures. Attempts have been made to make such containers out of cardboard and the like, but the results have not been satisfactory. The present invention aims to provide a container having many of the advantages of glass and tin but made of different materials. More particularly the invention combines an outer protective container and an inner sealing container in an improved unitary structure whichmay be readily filled manually or by the customary lling machinery. In dispensing the contents, the container may be opened and closed as often as desired. These and other advantages make the container attractive to the manufacturer, the packer and the consumer.

An object of the present invention is to provide an improved container from inexpensive material.

Another object of the invention is to provide an improved container from materials such as paper and cardboard.y

Another object of the present invention is to provide an inner container of thin material adapted to act as a sealing medium to protect against leakage and an outer container oi cardboard for preventing rupture of the inner container and to embody improved dispensing means therein. v

Another object of the invention is to provide improved means oi securing sealing and protective containers together by means of a neck portion adapted to serve as a dispensing outlet.

Other and further objects of the invention will be obvious upon an understanding of the illustrative embodiment about to be described, or will be indicated in the appended claims, and various advantages not referred to herein will occur to one skilled in the art upon employment of the invention in practice.

A preferred embodiment of the invention has been chosen for purposes of illustration and descriptionl and is shown in the accompanying drawings, forming a part of the specification, wherein Fig. 1 is a perspective view illustrating the exterior of a preferred embodiment of a completed container; y y y Fig. 2 is a perspective view illustrating the construction of one end of the outer container;

Fig. 3 is an exploded view illustrating thesev-` eral component parts of the container in position to be assembled;

Fig. 4 is a sectional -view illustrating the construction of a completed sealed container;

Fig. 5 is afragmentary sectional view illustrating a modified form of connecting means for the neck portion; y

Fig. 6 is a fragmentary sectional view illustrating another modified form of the neck portion; and

Fig. 7 is a fragmentary view illustrating the invention applied to other types of containers.

Referring again to the drawings and more particularly to the preferred embodiment illustrated in Figs. 1 toA 4 thereof, there is provided an outer container l, made of cardboard or the like and an inner container 2 substantially in the form of a bag, which maybe made of paper, waxed `or plain, glassine, Cellophane, Pliofllm and similar materials. The inner and outer containers are nested together so that the aperture 4 in the inner container registers with the aper- 'ture 5 in the upper end of the outer container to accommodate a neck portion 6 for securing' the inner and outer containers together and also for serving as a dispensingoutlet.

Referring to theelements l, 2 and 6 individually, the outer protective container l is prefer.

ably made of cardboardv or similar material. Each of the ends of the box may be provided with

flaps

1, 8 and 9 which are folded in in the usual way to close the ends and which are frequently termed tuck-in flaps. The flap Q at the lower end may be provided with slits I3 for locking the end of the flap in tucked in position. Any other suitable locking device or an adhesive may be vused with or without tucks where desired. In many cases no locking device is needed. While the neck portion retains the upper end closed, the flap 9 thereof, likewise, may be provided with a locking mechanism illustrated as slits I3 in Fig'. 2. At the upper end of the container, the flaps 'l and 8 are provided with recesses Ill and I I opposite each other to forni an aperture which registers with an aperturev 5 in iap 9. Thus when the upper end of the box is closed. an aperture is provided through the several flaps. In shipment prior to assembly with the other elements, the flaps may be in open position and the box folded about diagonal corners to save shipping space. While the preferred embodiment illustrates the box made of cardboard', it will be understood that various other types of material may be utilized advantageously.

The inner lcontainer 2 may be a bag closed at one end by folding as shown at ld (Figs. 3 and 4) and by adhering the ends together. Preferably the aperture A extends through the folded portions to provide astrengthened partfor securing the bag Vabout the neck portion aswill bedescribed later. While the particular fold I 4 illustratedis preferred, it will be understood that any other means of closing the ends may be utilized and in some cases, it may be desirable to have a seamless bag or one with the overlapped edges secured together in any suitable manner.

The preferred form of neck portion 6 is illustrated in detail in Fig. 4 in operative relation with respect to the inner and outer containers. Preferably the neck portion has a lower flange I on the inside of the containers and an upper flange i6 on the outside of the containers forced downwardly into clamping relation with the portions of the inner and outer containers adjacent the apertures si and 5 thereof. Prior to application, the flange I6 is preferably upright, as shown more particularly in Fig. 3. A suitable tool is utilized for bending the portion I6 outwardly and downwardly until it rmly clamps the containers against the flange I5 and holds them firmly in position. The neck portion 6 may have a sifter top I'I as ilustrated in Fig. 4 or a pouring outlet as illustrated in Figs. 5 and 6 with a closure I8 secured t-o the upper end thereof. lPreferably the upper end of the neck is threaded as illustrated at I9 and the closure is threaded at 20 so that it may be screwed on and oif to form a secure seal thereby to facilitate dispensing by the user. Since the portions of the inner bag adjacent the aperture 4 have a plurality of thicknesses due tol the aperture being through the fold I4, the neck portion 6 is effective on a reinforced part -of the bag -which minimizes the possibility of rupture. In addition, the clamping action of the neck portion cooperates to hold the folds together. Likewise the clamping action is effective to hold the flaps of the outer container in closed position. Thus the neck portion cooperates to strengthen the structure.

In assembling the parts, a form 2l may be prof vided as shown at the bottom of Fig. 3 having an insert 22 with a projection 23 adapted to t into "the recess on the underside of the neck portion 6to hold the neck portion in position on the form 2l. .When the neck portion 6 is placed over the projection 23, it is in position to register with the apertures 4 and 5 of the inner and outer con- .tainers when they are applied over the form.

After placing the neck portion 6 in position, the inner bag 2 is forced over the form so that the aperture 4 passes over the neck portion and the annular position thereof adjacent the aperture rests on the flange I5 of the neck portion. Thereafter the outer container with its lower end open and its upper end closed as shown in Fig. 3 is dropped over the form and the inner bag so that the aperture 5 registers with the neck portion 6. A suitable tool (not shown) is then utilized for forcing outwardly the portion I6 into a flange clamping the parts in position as shown more particularly in Fig. 4. Preferably, the neck portion is made of lead or other material, which may be bent into clamping relation with the parts. Thereafter, the closure I8 is applied and the package is complete except for filling. Suitable automatic machinery may be utilized for filling the packages from the open end. Thereafter, the open end of the bag 2 may be folded at 24 as shown in Fig. 4. and secured together by heat, adhesive or by other means. As a matter of fact, good results may be obtained in some cases merely'by folding the parts together without adhesives. The

flaps

1, 8 and 9 of the outer container are .then folded in as shown in Fig. 4 to close the lower end thereof and to provide a protective casing extending completely about the bag 2 which may be somewhat fragile. The slits I3 in the flaps 9 are engaged by the sides of the flaps l and 8 to lock the end parts in position.

A modified construction is illustrated in Fig. 5, wherein a suitable washer 26 is provided on the flange I5. The inner bag is preferably passed over the neck portion 6' and adhered to the washer 26. Thereafter the outer box is passed over the inner bag and a suitable washer 2 secured to the upper surface thereof by a suitable adhesive or by screwing the washer down utilizing the threads of the neck portion for this purpose. Thus the clamping action illustrated in Fig. 4 may be obtained either by the tightening action of the washer screwed into position or by the action of the adhesive or by a combination of the two. Preferably, the washer 2 is made of a fibrous material although it may be made of metal in some instances. In some cases, the adhesive may be omitted, in other cases, the washers may be omitted, but in the embodiment illustrated in Fig. 5, it is preferred to use both the adhesive and the washers, although neither is essential in the broader features of the invention. The closure I 8' may be provided with a sealing disc 28.

In the construction illustrated in Fig. 6, the neck portion 6 is provided with a lower ange I5" and a groove 29 immediately above the flange. The bag 2 and the box I may be forced over the upper end of the neck portion until they snap into the annular groove 29, which will hold them in position. A suitable adhesive may be l added if desired, but the groove alone has been found to give good results. The outer wall of the neck portion may have a friction surface 30 on which a friction closure I8" is forced into grip- L ping relation therewith as shown. A suitable disc 2.8" may serve as a sealing medium. The construction in Fig. 6 lends itself particularly to the use of wood or a similar material for the neck portion. The construction in Fig. 5 may be made of wood, metal, molded material and the like.

With certain types of containers, the inner sac 2 is not necessary and its elimination simplifies the construction. For example, fibre tube containers may be utilized with a suitable slip cover sealed to their open ends by an adhesive or held in place by friction alone. Likewise, boxes may be utilized which are performed on box making machinery and which are generally covered with a wrapper to seal all sides except the side or end which is left open for lling. The latter may be closed in any suitable manner by a cover.V The containerSI in Fig. 7 is intended to illustrate these general types of containers and the invention applied thereto. As illustrated in Fig. '7, the container 3l comprises an outer cylindrical tube 34 with its respective ends rolled inwardly as shown at 35 to provide shoulders for seating the end discs 36. A cylindrical tube 37 may flt within the outer tube with its ends abutting the end discs 36 to hold them in position against the shoulders formed by the rolled ends of the outer tube. An aperture 32 is formed preferably in one end of the container 3l and the neck portion 6 is secured in the aperture. The flange I5 of the neck portion fits on the inside of the.- neck portion with the part i6 bent downwardly to clamp the portion of the container adjacent to the aperture securely in position. The

other parts of the neck portion are identical with those described with reference to Figs. l to 4. It is to be understood that the neck portions 6' and i" illustrated in Figs. 5 and 6 respectively may ilso be utilized with the container 3 l.

It will be seen that the present invention pro- /ides an'improved container which may be made it a low cost of inexpensive materials. The con- ;ainer has many of the advantages of glass and metal containers. The outer container protects the inner inexpensive bag and cooperates with it to provide a secure seal. The package lends itself particularly to packaging powders, bath salts andthe like; however, its utility is not limited to .such products. The type of material in the inner bag may be changed to accord with the types of products desired to be packed therein in the embodiments of the invention utilizing the inner bag. The neck portion rigidly secures the parts together and serves to reinforce the upper end against ruptures or leaks. Likewise, the folded end of the bag at the opposite end forms a secure seal. The construction is fully capable of withstanding the rough usage to which it may be subjected and may be attractively decorated by inexpensive printing or lithographing.

As various changes may be made in the form, construction and arrangement of the parts herein without departing from the scope and spirit of the invention and without sacricing any of its advantages, it is to be understood that all matter herein is to be interpreted as illustrative and v not in a limiting sense.
