Circular Cross Section Container Patents (Class 493/108)
  • Patent number: 10773860
    Abstract: The present invention relates to absolute safe closure of beverages, food, medical bottles so that they cannot be opened and reclosed assuming the shape of first production in the factory. The first closing of the bottle's closure is only once in an absolute and tight manner, such that if the bottle is opened for the first time in any manner, it cannot be closed tightly and safely via intervention and engagement of the stopper with the neck of the bottle upon its closure for the first time. Using such closure manner, two parts are constituting one part such that they are non-detachable in any way, unless safety strip of stopper is tampered, that it cannot be reused as it was in the first case.

  • Patent number: 10709169
    Abstract: An apparatus for rolling papers into a non-cylindrical orientation is provided. The apparatus includes a rotatable non-cylindrical workpiece having a plurality of openings provided therein, a surface comprising a receiving indentation configured to receive and fit the rotatable non-cylindrical workpiece, a suction producing arrangement connected to the rotatable non-cylindrical workpiece, and a rolling paper. The suction producing arrangement draws air through the plurality of openings while the rotatable non-cylindrical workpiece rotates such that the drawn air draws the rolling paper toward and around the rotatable non-cylindrical workpiece, the rotation causing the rolling paper and a quantity of adhesive applied to the rolling paper to form a completed non-cylindrical rolling paper product.

  • Patent number: 8870730
    Abstract: A substantially crimpless and monolithic paperboard container lid and method of making same is provided. The lid comprises a single contiguous molded paperboard body configured to conformingly couple to a top periphery of a container for covering the container's opening. The body includes a sealing ring located adjacent the body's periphery. The sealing ring includes a sealing channel composed of a radiused cross-section that extends to a tangent ring terminating with a tab ring. The radiused cross-section and tangent ring assist providing a snug fit between the lid and the container. Despite being made from paperboard, the lid does not include one or more substantial crimps in the sealing ring. Having no substantial crimps, the lid fits onto the container and prevents fluid from leaking between the container's periphery and the lid.

    Abstract: A container having a casing made from composite carton and constituting a container body, which is covered on its inside by a barrier layer and a plastic layer deposited thereon, is produced in such a fashion that the casing is rolled over in an outward direction at one end to form a curled edge and, subsequently, a membrane is sealed onto the upper crown of the curled edge. A bottom is attached to the opposite end after the container is filled. In order to guarantee a sealed closure, the casing is tapered inwardly in a conical manner at its one end along a length which is larger than the circumference of the curled edge in such a manner that the outer diameter in the vicinity of the tapered end is smaller by approximately twice the diameter of the curled edge than the outer diameter of the casing. The end is then rolled over in an outer direction to form a curled edge and is then sealed by the membrane.

  • Patent number: 6135936
    Abstract: A bottom for a paper cup is formed by advancing a punch against a paperboard web to push the web against a cutting edge which cuts out a circular cup bottom blank from the web. The punch is kept in a forward state to clamp an outer peripheral portion of the blank immovably against a surface of a sleeve. A reciprocable draw is advanced against a center portion of the blank to push the center portion into a circular opening of the sleeve while maintaining the clamping force, to cause the center portion of the blank to become stretched. The clamping force is then progressively released to permit the outer peripheral portion to enter the opening and become bent to form a lip extending at a substantially right angle. The lip is compressed within a gap formed between the draw and a surface of the opening. Because of the stretching of the blank, pleats formed in the lip are only in the form of micropleats that are flattened in a non-folded over state.

  • Patent number: 5363982
    Abstract: A thermally insulated cup or container (30) includes a smooth outer shell (12S), a smooth inner shell (13S), a corrugated layer (11L) sandwiched therebetween, and a bottom closure (14). The inner shell, corrugated layer, and outer shell are formed by simply winding a continuous elongated paper sheet (10) in a three-layered spiral, then sealing them together. The corrugated layer forms many air pockets between the shells to thermally insulate the contents of the cup, and also provide structural strength. The paper construction of the cup makes it biodegradable and recyclable, and the simple construction method of the cup makes it easy and inexpensive to manufacture.

  • Patent number: 5081820
    Abstract: A method for applying an end plate to a container body includes applying a heated end blank made of deformable material to one end of the container body and creating a pressure difference between the two sides of the end blank to seal the edges of the end blank to the edges of the container body. The apparatus for applying an end plate to a container body includes a jacket having a chamber into which the container body can be fitted. A vacuum source is provided at one end of the jacket and a lid or clamping device is located at the opposite end of the jacket. The chamber into which the container body is fitted is not as deep as the container body so that when the container body is fitted into the chamber, the upper edges of the container body extend above the surface of the jacket. In that, the end blank can be applied to the container body and thereafter, the clamping device is used to clamp the end blank between the upper edge of the jacket and the clamping device.

  • Patent number: 4583964
    Abstract: A method and an apparatus are indicated for the production of a cylindrical packing tube which is open at one end and closed at the other, is made from deformable tear-resistant packing material and is intended, in particular, for tampons used in female hygiene, wherein a portion of the packing material is drawn by suction onto a winding spindle provided with suction apertures and through the rotation of the winding spindle is wrapped around the latter, while the overlapping ends of the portion are joined together to form the packing tube, whose end projecting beyond the winding spindle is closed, whereupon the packing tube is removed from the winding spindle. The method is characterized in that that end of the cylindrical packing tube which projects beyond the winding spindle is held fast and during the rotation of the winding spindle is closed so as to form a twist. The method permits the production of a uniform closure pattern of the packing tube irrespective of the shape of the tampon insertion end.

  • Patent number: 4551123
    Abstract: A container comprises a paper base member covered all around by a heat-shrinkable plastic film. Air is removed from a space formed by the film in which the paper base member is disposed to bring the film against the base member, and at least a part of the film is sealed for closing the space. The base member is either originally formed into the shape of the container, or later formed into the shape of the container to define at least one open end. The open end is covered by a metal lid. A method of making the container includes covering the base member with heat-shrinkable plastic film forming a double wall with the base member in a space between the double wall, removing air from the space between the double wall and sealing the space. Heat applied to the container, for example for sterilizing contents of the container, also shrinks the plastic film to produce a wrinkle-free fit between the film and the paper base member.
