Abstract: A container closure includes a cap for sealing a container against leakage, and a brush-like pliable member for spreading contents of the container. The cap includes a top wall, an internally threaded skirt depending from perimetrical portions of the top wall, and a stem depending from a central portion of the top wall. The brush includes a paddle-shaped member or a plurality of bristles which depend below the stem for brushing the contents of the container onto a surface. The cap and the brush are formed as a one-piece structure. A method of forming the one-piece cap and brush includes the step of molding the cap using a specially configured mold which has at least three relatively movable parts for defining a mold cavity and for effecting a pop-off type of ejection of the threaded skirt from the mold once the integral cap and brush have been molded.

Abstract: A container closure includes a cap for sealing a container against leakage, and a brush for spreading contents of the container. The cap includes a top wall, an internally threaded skirt depending from perimetrical portions of the top wall, and a stem depending from a central portion of the top wall. The brush includes a plurality of bristles having (1) mounting portions which are secured to the lower end region of the stem, and (2) applicator portions which depend below the stem for brushing the contents of the container onto a surface. The cap is a one-piece structure having its brush-supporting stem formed integrally with other parts of the cap.

Abstract: An improved pile-type, fin weatherstrip includes an elongated V- or U-shaped barrier fin bonded to a base strip and located between a pair of upstanding pile fiber arrays. The barrier fin is formed of thermoplastic film which is preferably smooth, but which may be roughened, dimpled or otherwise provided with a large number of pockets, or which may have a flocked surface. A lubricant grease is provided in the channel shaped cavity of the barrier fin, which lubricant is progressively dispensed in response to a wiping action type of movement which occurs when the barrier fin is compressed by the pile arrays during usage. The lubricant grease is exuded progressively over the useful life of the weatherstrip toward the free edges of the barrier fin located at or near the forward projecting face of the weatherstrip where such grease is dispensed in small amounts to decrease breakaway force, lower sliding friction and improved air infiltration characteristics.

Abstract: The constituents of a flow of thermoplastics material or the like are mixed and blended by passing the flow through a mixing structure which defines an array of elongate side-by-side passages. The passages are not all alike in that at least some of them have configurations which taper along their lengths to degrees or in directions that differ from the configurations of others of the passages, whereby the flows of fluid which discharge from the differently configured passages do so at differing velocities. As the discharging flows of differing velocities recombine to form a common flow having a uniform velocity, a desirable type of mixing and blending action results. In preferred practice, adjacent ones of the passages are tapered oppositely along their lengths to converge or diverge such that fluid flowing through the converging passages is caused to increase in velocity, while fluid flowing through the diverging passages is caused to diminish in velocity.

Abstract: A pinch cap has a top wall with edge portions which form a circumferentially-extending rim. A pair of spaced, D-shaped, finger-receiving wells open through the top wall. The wells are formed by curved and straight side walls which depend from the top wall, and by a pair of D-shaped bottom walls. Locking formations are provided on the outer faces of the curved side walls for holding the cap in place in a container opening. During insertion of the cap into a container opening, the locking formations engage portions of the container located at spaced positions around the container opening and cause the normal configuration of the cap to distort briefly as is needed to permit the locking formations to pass through the container opening.

Abstract: A closure cap particularly suited for use with containers such as milk bottles includes multiple sealing areas as well as frangible locking means. The locking means is located near the lower rim of a skirt portion of the closure cap. If the locking means has not been tampered with, an interlocking engagement between the locking means and a complementary portion of the container retains the cap on the container. If the locking means has been tampered with, the cap can be removed from the container. A visual inspection of the closure cap readily indicates whether the locking means is in tampered or untampered condition. In one embodiment, the cap can be repeatedly snapped into place on the container, and in other alternative embodiments, the cap can be repeatedly threaded onto the container. The multiple sealing areas not only seal the contents of the container, but one of the areas also prevents dust, dirt, or other contaminants from having access to the other sealing areas.

Abstract: A carrier for releasably receiving, retaining, carrying and hanging hook portions of a plurality of coat hangers includes a C-shaped member having upper and lower portions which overlie each other and which extend substantially in a common plane. The upper leg portion is of sufficient size relative to the size of one's hand to effectively distribute the load of a plurality of garment-carrying hangers across the width of one's hand. The lower leg portion is provided with two openings which extend substantially perpendicular to at least a part of the lower leg portion. One of these openings serves to releasably receive and retain hook portions of a plurality of hangers with such hangers extending substantially perpendicular to the common plane. The other of these openings receives a ring for supporting the carrier on a wall-mounted hook.

Abstract: A childproof, push-pull container closure includes a body portion having an opening through which container contents may be discharged. A cap is secured to the body portion and is adapted for movement axially of the body portion. The cap is mounted to the body portion by means of a formation extending from the upper surface of the body portion. In one embodiment, the formation defines recesses spaced 180.degree. from each other and located near the periphery of the body portion. The cap includes a top wall having a depending skirt along the lower edge of which an annular, radially inwardly directed flange is included. When the cap is in a closed position, the recesses and the annular flange are engaged in interlocking relationship. In order to unlock the cap, the skirt is distorted by applying force to the skirt at appropriate opposed circumferential locations until the annular flange is moved from the recesses.

Abstract: A vacuum sizing apparatus is positioned downstream from an extruder along a path followed by a body of thermoplastics material as the body exudes in a heated, deformable state from the extruder. The apparatus includes structure defining an elongate sizing surface extending along the path of travel of the body. A multiplicity of vacuum channels are formed in the structure and open through the sizing surface for drawing outer wall portions of the body into conforming engagement with the sizing surface as the wall portions cool and rigidify while moving along the sizing surface. The structure includes a plurality of side-by-side structural segments, each of which defines a portion of the sizing surface, adjacent ones of which have mating side walls. The vacuum channels are of small cross section and are formed as grooves milled or ground in the side walls of the segments. A clamping system releasably clamps the segments together and permits their disassembly to provide access to the vacuum channels for cleaning.
