  • Patent number: 4239164
    Abstract: A container is disclosed for dispensing strip material having a light-sensitive layer on one side. A slot through which the strip material can be pulled from a roll of such material within the container has a first lip and a second lip spring resiliently urged toward the first lip. The lips are shaped so that tension in the strip material therebetween produces a resultant force which opposes the resilient force to reduce or eliminate pressure between the light-sensistive layer and the first lip.

  • Patent number: 4204618
    Abstract: A dispenser for a roll of strip comprising an open top casing. A cover is pivotally mounted on the casing for closing the top thereof. Disposed within the casing is a roll of strip having transverse slits formed therein at predetermined distances along the strip. The free end of the strip to be removed from the roll of strip exits from an opening located between the casing and the cover. Extending from the casing are transversely spaced tracks that project outwardly and downwardly from the casing, and over which advances the free end of the roll of strip. Extending from the cover are outwardly and downwardly transversely spaced guides, which overlie, respectively, the transverse tracks to form passages therebetween. The free end of the strip travels through these passages. The tracks and guides are correspondingly curved to bow the free end of the roll of strip at the transverse slit advancing through the passages to open the slit.

  • Patent number: 4108390
    Abstract: A low cost container for paper tape or the like from which the contents may e manually dispensed but which prohibits reinsertion of a tape once removed. The internal structure includes a maze-like path or labyrinth through which the tape may be easily pulled for removal. Efforts to move the tape backwards forces the tape into one or more small cavities which are filled by a small quantity of tape, thereby prohibiting further reinsertion.

  • Patent number: 4092817
    Abstract: An improvement in a device for advancing an end portion of a strip of heat sealable film along a path from a cartridge to an applying station, sealing the end portion across the lip of a cup and severing the end portion from the strip of film. The device includes a perforating member which cooperates with a support surface in the cartridge before the end portion of the film is advanced to the applying station to perforate around a small portion of the film. The applied film can then be separated along part of the perforations and the small portion can be bent aside to provide an opening through which a drinking straw can be inserted into the cup.

  • Patent number: 4079874
    Abstract: Dispenser for web material in roll form comprises a box or like container in which the roll is rotatably received, and which defines a web path which extends between first and second members, the first member being a severing member pivotally mounted for rocking movement about an axis transverse to said path and having a serrated or other tearing edge across an outer part of the path against which an outer end part of the web can be pulled at an angle for severance from the roll and a ridged or other clamping portion inwardly of said axis for cooperation with the second member so that when the web is pulled against said tearing edge an inner part of the web is automatically clamped against outward movement.The dispenser is particularly useful for domestic paper towelling, plastics film or foil.

  • Patent number: 3986479
    Abstract: Towelette dispenser and vapor impervious pouch containing a roll or web of absorbent material, such as nonwoven fibrous towelettes pre-moistened with a chemical-containing aqueous or other fluid solution. The pouch is sealed before use to prevent the loss of moisture from the pre-moistened towelette roll and is opened at the point of, and at the time of, first use. A double lid is adapted to provide moisture seal between usages of the pre-moistened towelette, while reducing dehydration of the opened towelette pouch within the dispenser. Feed slit adaptations in the lid provide for selective tearability of individual towelette portions from the roll. The dispenser is adapted to provide a low center of gravity, and the base of the dispenser can cooperatingly engage a wall-type holder. The towelette roll contains a leader adapted for ease of feeding through the feed slot upon first use.

  • Patent number: 3972458
    Abstract: A paper holder for supporting a paper roll and for tearing it to a given length as it is reeled off the roll. The holder comprises a casing which rotatably supports a paper roll, and a retaining cover which is pivotally mounted on the casing at its one end. Casing includes a bearing surface over which a length of the paper web extends as it is reeled off the roll, and the retaining cover includes an abutment adjacent to its other end which bears against the bearing surface with the paper length interposed therebetween. Adjacent to its other end, the cover is also formed with a slot for passing the paper length upwardly therethrough. The paper length which is let through the slot is turned back and then allowed to hang down.
