13 Claims.
This invention relates in the main to fibre containers, and while it has more particular reference to the provision of a container for the packaging of milk and similar liquids it will be 6 apparent that its several features have other valuable application and uses.
The invention has for its principal object th provision of a fibre container of simple, economical construction, which will be liquid proof, sanitary, and easily opened and handled by the consumer. 1
In comparison with the ordinary milk bottle generally in use by dairies, the invention contemplates the provision of a fibre container which 16 may be more cheaply manufactured, which will be lighter in weight, which will occupy less space in'storage and in the milk wagon, and which will be more sanitary.
The invention contemplates the construction of a milk bottle without metal and of liquid proof fibre parts, of simple construction andjoined together in easily formed liquid proof seams.
It contemplates also improvement in the pack- 5 aging and dispensing of the milk, with less opportunity-for contamination than is provided in the use of the glass milk bottles. In this regard the invention contemplates the provision of fibre containers which are wholly sealed in the can factory and which are only temporarily opened by the dairyman for filling prior to delivery to the consumer.
In comparison, also, with the glass milk bottles currently in use, the invention contemplates the provision of a lighter package and one which is rectangular or square in cross-section so that a greater number of containers may be stored ,in a given space in the wagon and/or in the carriers provided to the milkmenfor their delivery.
Numerous other objects and advantages of the invention will beapparent as it is better understood from the following description, which, when taken in connection with the accompanying drawing, discloses a preferred embodiment there- Referring to the drawing:
Figure 1 is a perspective view of a container embodying the present invention and illustrating the manner of opening the container;
Fig. 2 isa perspective view of the upper part of the same, illustrating the container fully sealed, as after filling;
5 Fig. 3 is a fragmentary perspective view of the opened container in the position for discharging its contents;
Fig. 4 is a fragmentary enlarged sectional view taken substantially along a vertical plane indicated by lines 4-4 in Fig. 1; and
Fig. 5 is a perspective view of one form of cover for the container.
The container shown on the drawing and which constitutes the embodiment of the invention at present preferred is formed of fibrous material which has been suitably treated with parafilne or other water resisting substance to make it liquid proof. It consists primarily of'a rectangular body Hand bottom and top closures I2 and I3.
The body ll consists of or may consist of a single sheet of material folded at right angles to provide the four side walls l4. Each of the vertical edges of the sheet is provided with. a flap 15 adapted to engage and be secured to the adjacent face of the adjacent wall by a suitable adhesive to form a liquid tight side seam. Each of. the bottom and top end closures l2 and I3 consists or may consist of a disk of fibre material interlocked with the adjacent end of the body. The body is bent obliquely inwardly at l6 adjacent each end to produce a shoulder for the end and to effect an inwardly inclined reen forcing truss portion. This body Wall is thence bent outwardly in a relatively sharp corner to provide a horizontally outwardly extending ledge on which the end rests. The sharply bent outwardly extending portion or ledge l'l cooperates with the inwardly inclined truss portion IE to constitute a rigid non-collapsible structure which resists outward and inward movement of the body wall and insures against vertical collapse due to any longitudinal strains at the ends of the container. The relatively sharp angle formed by bending outwardly the body wall at the upper end of the inwardly inclined truss portion i6 is such that the plane of the outwardly extending portion ll intersects the plane of the inclined truss portion l6 substantially within the material of the body wall of the container.
The upper end closure I3 is seated upon the ledge I1 and the extreme edge of the body is then folded downat l8 to provide a horizontally extending body part or terminal portion [9 above or outside the end closure. The lower end closure is similarly seated and held.
The parts I! and I9 of the body define an inwardly opening horizontal channel in which the edge of the closure is engaged and is held by a suitable liquid proof adhesive connecting the interengaging faces. The aforesaid reen forced truss construction at the ends of the container insures against any tendency of the latter when filled to collapse due to longitudinal strains such for example as might be caused by 5 stacking the filled containers.
The bottom closure i2 is or may be of simple, imperforate sheet construction. The top closure 13 is preferably comprised of two plies conveniently formed by folding tw'oopposite sides of a sheet of suitable dimension along lines of fold 2| and 22 located respectively at the front and 15 opened to provide a filling and dispensing opening. Theupper ply indicated by reference character is scored or cut through or nearly through along lines 24 and (Fig. 1) converging to and meeting adjacent one of the comers of the container, these lines preferably being in parallelism with the side edges of theclosure. V
The lines and 25 are preferably extended into parallelcuts 28, as may be observed in Figs. 1 and 3. The lower ply 21 is similarly scored upwardly from its lower face along lines of score 28, spaced inwardly, however, somewhat from the lines of score 24 and 25to provide a shoulder 29, which is offset vertically or upwardly in. respect to the marginal portion of the end closure, the pur- 0 pose of which shoulder will be presently more fully explained. That is to say the opening through the inner ply of the top is a little smaller than the opening through the outer ply (Fig. 3),. Likewise also the inner scoring extends along 5 parallel lines 3| to adjacent the ends of the parallel scores 26 of the top ply and across score line 32 is provided in the lower ply to connect the rear ends of the score lines 3|. The scoring may be accomplished before the sheet forming the top closure ,is folded, in which event it is desirable that sufficient material be left at the bottoms of the scores to permit the material to be folded and secured inflnal relationship or the folding may be accomplished and the plies lightly held together'with adhesive and the scoring then acaccomplished, in which event the scoring may extend completely through the pliesin which it is provided.
At the rear the material of the top closure is preferably extended upward and'outside of the adjacent overlying part IQ of the body and is bent up at 33 to provide an upwardly extending tab 34 which may be perforated at 35. This tab provides a convenient hand hold to be grasped to lift the containerfrom its storage position or from the carrier, and the container may be hung upon anail. A staple may be used at the bend 33 to hold the plies together and to strengthen the parts connected to the tab 34.
In the use of the container for milk it is intended that the container thus described shall be completely closed by the can manufacturer and shall be received by thedairyman with the open ing fiap unsevered fromtheremainder of the end 65 closure. Immediately before putting the milk into the container it is intended that the dairyman complete the severance alongthe score lines and lift the flap about the unsevered and unscored connection between the rear ends of the score lines 26 of the top ply. The severance along the score lines may conveniently be accomplished by 7 ,5 after the flap is swung back to its initial closed 7 position so that its edges rest upon the shoulder 29, already described.
It may be secured in this position by a sticker or paper sheet 36 arranged across the fiap, the adjacent surfaces of the end closure and over and about the adjacent channel parts of the body which enter into the end seam, as may be observed in Fig. 2. The sticker or paper sheet 36 forms a seal which is removable or may be torn away by the customer to permit reopening of the flap and the pouring of the-milk.
It will be apparent that a container constructed and filled in accordance with the foregoing will be wholly or substantially wholly sanitary and may be delivered by the can manufacturer to the 'dairyman in sterile condition. The can may be opened just before filling and quickly closed, with minimum opportunity for contamination of the contents, and after closing maintained in sanitary condition until delivery to the consumer.
, By arranging the pouringopening ata corner of the container, the milk may be poured in a controlled and even stream through the opening and with minimum opportunity for the soiling of the sides of the container when the pouring is interrupted.
- It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the form hereinbefcre described being merely a preferred embodiment thereof.
