  • Patent number: 4105152
    Abstract: A paperboard container comprises an opened top receptacle adapted to contain foodstuffs therein and a separate cover telescopically disposed on the receptacle. The receptacle comprises a bottom panel, a pair of laterally spaced end panels, a back panel and a front panel hingedly connected to the bottom panel. A pair of lock flaps are hingedly connected to opposite ends of the front panel to each engage within a slot defined on a forward edge of a respective end panel. A slit, formed on the end panel, defines a lock tab adapted to bend outwardly to receive the lock flap thereunder when the front panel is moved to its closed position. The receptacle is adapted to be loaded with foodstuffs, such as asparagus, upon opening of the front panel which is thereafter closed for reception of the cover on the receptacle.

  • Patent number: 4073317
    Abstract: A clamping device comprises a body portion having a pair of parallel flanges secured to opposite sides thereof and a slot formed through one end of the body portion. A ring is pivotally mounted on the flanges and suitably sized to freely pivot over the one end of the body portion whereby a first end of a strap may be inserted through the ring and reverse folded under the strap. A second end of the strap is then inserted through the slot and is pulled to tighten the strap about an article, such as an insulated pipe. The point whereat the ring is pivotally mounted on the body portion is then pivoted into over-center relationship relative to the point whereat the second end of the strap engages the slot to superimpose the body portion over the second end of the strap to tightly clamp the same about the article.

  • Patent number: 3971294
    Abstract: Apparatus for cutting an annular groove about a rotating cylindrical member includes a rotating cutter positioned in cutting relation to the outer surface of the cylindrical member and including a plurality of cutting edges, each forwardly angled in relation to the direction of rotation of the cutter. The cylindrical member and cutter rotate in the same direction so that an annular groove or channel is cut in and along the outer surface of the cylindrical member. Sealing apparatus is included for providing sealing between the outer surface of such member and the inner surface of a member overlying such first-mentioned member. The sealing apparatus is of resilient material and is seated in the channel. The sealing apparatus includes a pair of elongated ribs angled in the same direction, and in contact with each other when in such sealing situation, with the elongated side surface of one of such ribs in sealing contact with the inner surface of such overlying member.
