CARTON CONTAINER Filed Jan. 17, 1938 f/z nm rox? Patented May 27, 1941 2,243,378 CARTON CONTAINER Carl Wilhelm Hartmann, Lyngby, Denmark Application January 17, 1938, Serial No. 185,454 In Denmark January 22, 1937 My invention relates to carton containers 3 Claims.
which especially are intended for use in retailing milk, lubricants, cleansing agents and other liquids or pulverulent materials.
The main object of my invention is to provide a container of such shape that a number of containers can be stacked in a compact space, especially when they are stored as half-finished goods at the place of consumption for being finished directly before their being filled. Furthermore the object of my invention is to provide for the container being adapted for use in connection with the customary filling machinery, especially for milk.
Still another object of my invention is. to produce a sealing means for the container, which is I liquid-tight and will withstand a material internal or external pressure. Furthermore the said means should produce a reinforcement of the rim of the body part. Finally it should be possible to effect the sealing after the container having received itscontents of liquid, pulverulent material or the like.
According to the main feature of my invention the container consists of a seamless body part of end it is adapted to be opened in discharging the contents. At this end the body part may have an aperture closed by a removable cover.
According to a further feature of my invention the inserted disc is held in position through the intermedium of a ring embracing the body part.
The body part may have a skirt projecting beyond the inserted disc and externally receiving the ring.
Preferably the ring is produced from elastic material so that in being appliedit will compress the skirt beyond the disc. The ring may consist of more layers of paper pasted together and it may be produced separately, i. e. independently of the body part.
The invention also relates to a method of securing a disc in a skirt of moulded fibrous material .in producing a container of the kind in the disc.
' question. It is a feature of this method that at the exterior of the skirt is arranged a ring which forces the skirt inwardly against the edge of In connection with certain'embodiments of the invention, e. g. when the container has a frusto-conical 'body part which is to be closed at the base, the ring is displaced on to the skirt in a direction outwardly against the free edge of the skirt.
Other features of the inventionwill appear from the following description of the invention with reference to the drawing.
On the drawing:
Figure 1 shows an axial section according to my invention,
Figure 2 shows, on a larger scale, a fragment at the container bottom of an axial section of the container in its original shape, showing a detail which does not appear from Figure 1,
Figures 3 and 4 show a similar fragment illustrating different steps during the sealing of the container.
The container shown in Figure 1 consists of an inverted cup-shaped body part III. In the upper end' wall l2 of the same, which in a uniform curvature l4 merges into the cone-shaped side wall I6, is formed an aperture closed by an inserted metal cover I8. At the bottom the side wall I6 has an annular shoulder and below the same a skirt 22 terminating in a peripheral external bead 24, see Figure 2. The body part of a container has no lateral seam and may be produced, e. g.,
by pressing fibrous material in a heated mould.
The lower aperture of the body part is closed by a disc 26, egg. a cardboard disc, materially thicker than the side wall I6 of the body part. This disc is inserted from below into the skirt 22, which initially is somewhat flared outwardly as it appears from Figures 2 and 3, it being flush with the side wall. When the disc 26 is in position it abuts on the shoulder 20 and the disc is of such size that its peripherical edge abuts on the skirt 22 in this position.
The disc 26 may be forced into position in flat condition. However, it may also be held tensioned in a curved spherical shape by suitable means and introduced with the convex side inwardly. When the disc is then released it will spread somewhat in returning tothe fiat shape whereby the abutment pressure at the periphery of the disc will be increased.
The shoulder 20 is formed by means of a part 30 of the body part having, at least internally, a substantially constant cross-section, i. e. this part is substantially cylindrical; see Figure 2. The configuration shown is suitable for the former body used in connection with the production of the body part. It furthermore involves that prior to the insertion of the bottom a number of body parts may be interposed wholly into each other so that during transport and storing they occupy a small space only.
When the disc 28 is in position a ring 28 is forced on to the exterior of the skirt 22 in a downward direction; see Figure 3. Preferably this ring is produced from a somewhat elastic material and initially its inner diameter is equal to or somewhat less than the outer diameter of the skirt 2! at the location of the shoulder II. For instance the ring may consist of several layers of paper pasted together and it may be produced from a paper tape wound to a cylinder from which the rings are cut off.
The ring 28 is forced so far on to the skirt 22 that it substantially abuts on the head 24, see Figure 4. Preferably the ring has such width that it extends from the level of the bottom side of the disc 28 to the head 24 so that the skirt 22 is reinforced in itsfull width. In putting on the ring the skirt 22 is forced inwardly. If necessary it may be'pre'vented by special means that hereby the skirt is pleated. When the skirt has been forced in it is approximately cylindrical, see Figure 4, and as its material has been somewhat compressed, that is to say the thickness thereof has been increased, the inner surface of the skirt will project inwardly relatively to the edge of the disc 2' so that the disc is effectively secured against outward displacement. If desired the ring 28 may be secured in position by an adhesive.
The ring 28 may consist of other material than the fibrous material which, however, must be preferred in most cases as then the ring will resemble the remainder part of the container. As, however, the ring will not touch the contents of the container it may consist of metal. If desired the ring may consist of wire which is wound around the skirt in one or more turns and the ends of which are then twisted together.
during the sealing thereof. The invention is not restricted to containers with circular crou-section.
Having thus fully described my invention Ili claim as newand desire to secure by Letters Patent:
1. A container comprising a seamless body part produced from pressed molded fibrous material, the cross-section of which is increasing uniformly from one end to the other-end and having at the first-named end an integral end wall with an aperture closed by a removable cover and at the other end an extended skirt forming a shoulder; and a .disc adapted to abut against 'the shoulder in closing the container.
2. A container comprising a seamless body part produced from pressed molded fibrous material, a cross-section of which is increasing uniformly from one end to the other end and having at the first-named end an integral end' wall with an aperture closed by a removable cover.and at the other end an extended skirt forming a shoulder, said skirt having a reinforcing bead at its free end, and a disc adapted to abut against the shoulder in closing the container.
3. A carton comprising a seamless body part open at least at one end and having a skirt at thisend,adiscinsertedintheskirtinsuch manner that the latter projects outside the disc and aring embracing the projecting part of the skirt and forcing it inwardly at least flush with the edge of the disc by compressing the skirt material outside the 'disc so as to lock the latter in position, said ring consisting of several It should be remarked that the sealing, means described may be used at one or both ends of the body part of the container.
