2 Claims.
The invention relates to new and useful improvements in containers made from paper, cardboard, and other fibrous materials.
An object of the invention is to provide a fiber container wherein the body portion is tightly sealed and closed after the product is placed therein by non-metallic closure members without the use of adhesives.
A further object of the invention is to provide a container of the above type wherein the body portion is closed by a sealing disk of relatively thin material which is pressed into tight sealing engagement withthe inner wall of the body portion by a heavy fiber retainer disk. v
Another object of the invention is to provide a container in which the body wall includes an outer cylindrical member and an inner liner member contacting therewith, and wherein said container after it is filled, is closed by a sealing disk extending all the way across the open end of the container and folded down onto the outer wall thereof, said sealing disk having a depression therein after it is applied to the container, which depression is surrounded by a cylindrical wall contacting with the inner wall of the liner, and wherein heavy fiber retainer disks are disposed in said depression and dimensioned so as to force the cylindrical wall into tight sealing contact with the liner.
A further object of the invention is to provide a container of the above type with a reclosure cover which is secured to the body portion by a sealing tape.
In the drawing Figure 1 is a sectional view through a container embodying the improvements.
Figure 2 is an enlarged section of a portion of the container at the closure end thereof.
Figure 3 is a view similar to Figure 2, but showing a slightly modified form of the wall structure of the container.
The improved container includes a body I which is Preferably cylindrical. This body portion is made of paper or other fibrous material. The body wall may be made from a web which is convolutely wound or from a web which is spirally wound. Disposed within the container is a 2, which is preferably formed of fibrous material treated so as to .be moisture-proof and/or oil-proof, depending upon the purpose for which the container is to be used. This liner 2 terminates at the bottom end at 3, which is spaced away from the lower end or the body portion I. Placed in the lower end of the body and against the end of the liner wall is an end liner 4, of similarmaterial to the liner 2.
Inserted in the body against the outer face of the end liner 4 is an end member 5 which is provided with a flange 6 projecting outwardly from the end member 5. This flange which terminates short of the lower end of the body wall I is initially formed, and then the body wall isrolle'd or curled around the flange and against the inner face thereof and also against the under face of the end member 5. This forms a very strong, durable seam for joining the bottom end member to the body of the container.
At the upper end as shown in Figure 2, the liner terminates at 1, which is a short distance below the end 8 of the body wall I; This completesthe body of the container, and after it is filled with the chosen product, then the body is closed and sealed by a sealing disk 9. This sealing disk 9 is laid across the open end ofthe body and a retainer disk In dimensioned so as to fit fairly tight within the liner is placed against the sealing disk 9 and the disk is forced down into the liner. This formsa depression in the sealing disk which is surrounded by acyIindrical wall l I, and this cylindrical wall is clamped tightly against the liner 2 by this retainer disk II). This forms a seal which prevents the contents from passing around the end of the liner. As shown in Figure 2, a second retainer disk I2 is placed against the sealing disk 9. This retainer disk I2 is dimensioned so as to make a substantially tight fit within the inner wall of the body I. The result is that a second depression or step is formed in the sealing disk 9 which is surrounded by a cylindrical wall I3, and this cylindrical wall I3 is clamped against the inner wall of the body I so as to provide a tight seal therewith. This sealing disk 9 extends beyond the limits of the body wall I and is bent downwardly at M against the outer Wall of the container: body. When the retainer disks are forced to their seats in the container body, the sealing disk is so firmly pressed into tight sealing contact with the liner and body that no adhesive is necessary to complete the seal. The packer merely places the sealing disk across the open end of the container and forces the retainer disks against the sealing member and into the body and these retainer disks become a physical closure means for completing the closing of the container body.
No other closure means is necessary for the sealing of the container, but it is preferred to trainer is opened and which may also be used to provide a second or auxiliary seal for the complete package.
This reclosure member as shown in Figure 2 includes a disk l5 which is provided with, an outwardly extending flange 96 arranged substantially at right angles thereto. A collar I1 is provided and the disk i5 is inserted therein leaving a portion of the upper'part of the collar which is rolled or curled inwardly as at I8 against the inner face of the flange and the outer face of the member l5. These parts are preferably secured together by any suitable adhesive. The collar i1 is dimensioned 'so that it makes substantially tight frictional fit with the outer wall of the container body I. The sealing disk 9 is folded downwardly as indicated at 84 and the collar at H contacts therewith and holds it in its folded position and pressed against the outer wall of the container so as to further insure a seal between the body wall and the sealing disk 9. Furthermore, a sealing tape i9 is applied so as to lap partway onto the collar H or skirt of the reclosure member and partway onto the body wall. This makes a final seal for the container and it also holds the reclosure cover in assembled position on the closed container.
When it is desired to open the container the tape is out along the lower edge of the collar and then the reclosure cover is removed. This exposes the outer retainer disk M which may be pried out and then the closure disk to can be pried out and the sealing disks ruptured so as to provide an opening through which the contents may be removed. This, sealing disk 9 is. preferably made' of Cellophane or glassine or some other suitable lining material which is impervious to moisture. This sealing disk may also be treated or made of a material which i oil-proof. After the container is opened so as to give access to the contents, the reclosure cover may be applied at any time for temporarily closing the container.
In the form shown in Figure 3 the liner 2 is extended as indicated at In. so that it projects beyond the end 30.. of the body wall 1. In this form of construction a retaining disk Ella and a retaining disk I211, both of the same diameter, are placed against the sealing disk 9 so that it is forced down into a liner, providing a cylindrical portion Ila which is tightly pressed by the retainer disks into sealing engagement with the inner surface of the liner 2. This sealing disk extends over the edge or the liner and downward, a indicated at Ma, where it contacts with the outer wall of the liner. The reclosure member is formed with a collar I'la which is so dimensioned that it makes a frictional contact with the depending portion Ila of the sealing disk and holds it in tight engagement with-the outer wall of the liner. The closure tape l9 overlaps the lower end ofv the collar and the adjacent upper end of the body wall and forms Instead of providing two disks Illa a final seal. and I'm, a single disk may be used in lieu thereof.
While the sealing disk is. described above as held in tight sealing contact by the inserted oversize retainer disk, it may be desirable in some instances to use an adhesive for securing the sealing disk to the body of the container. Any
form of sealing material may be used, but preferably a thermoplastic sealing material which is applied to the peripheral portion of the sealing disk before it is attached to the container. If
this thermoplastic sealing material is applied to the underface of the sealing disk in the region where it will make contact with the inner side and end of the body wall, en heat may be applied to the disk when it is attached to the end and will be caused to firmly adhere thereto.
It is obvious that many changes in the selection of the materials and the details of construction may be made without departing from the spirit of the invention as set forth in the appended claims. 1
