ROBERT lVYDE/V BY United States Patent 3,220,657 CLQSURE-DESPENSER CAP FGR FLEXIBLE LIQUID CONTAINERS Robert Nyden, Manhasset, N.Y., assignor, by mesne assignments, to The Heekin Can Company, a corporation of Delaware Filed Feb, 24, 1964, Ser. No. 346,979 11 Claims. (Cl. 239579) The present invention relates in general to improvements in container closures and dispensers, and relates in particular to a novel and improved closure-dispenser for flexible squeeze bottles containing viscous fiuids.

The container closure of the present invention is of the type shown in my prior United States Patent No. 2,961,169, and constitutes an improvement thereover. Such type of closure, as disclosed in my aforesaid patent, constitutes a tubular closure member slidably mounted withinthe neck of a flexible and squeezable container, the closure member having an outlet aperture and being slidable between a raised position in which the tubular member projects from the container neck and exposes the outlet opening for the dispensing of fluid when the container is squeezed, and a lowered position in which the closure member is located Within the container neck, the outlet aperture is covered, and the container is sealed by said closure.

Longitudinally slidable valved closures of this type are used as dispensers for flexible bottles containing both liquids and creams of viscous fluids. Where a liquid is to be dispensed, the closure and dispenser cap carries a tube which extends to the bottom of the container, and the liquid is emitted as a spray when the container is squeezed. Where a cream, such as a cosmetic hand tion, is to be dispensed, the tube is omitted and the cream is dispensed in a stream. The improved closure of the present invention is adapted to be used for dispensing creamy or semi-viscous fluids in streams, and is particularly intended to eliminate some of the difliculties heretofore encountered in dispensing fluids of this kind.

Conventional dispenser closures of the type described above are subject to the disadvantage of being incapable of preventing some of the liquid from collecting on the interior of the dispenser cap and then dripping onto the exterior of the bottle. Because of the slippery nature of the creamy liquid, it becomes extremely difficult to wipe the liquid completely away from the exterior of the bottle, and even if this were possible, the wiping itself would represent a considerable inconvenience. In addition, the cream accumulated on the exterior surface of the dispenser cap is scraped to the top of the cap when the latter is depressed to its sealing position, and collects under the rim thereof and around the upper surface of the bottle neck, often causing unpleasant odors, and caking to interfere with the sliding action of the cap.

Another disadvantage found in the use of such closures is the tendency for the fluid to leak out between the inner wall of the container neck and the dispenser cap, both in the open and closed positions of said cap.

It is accordingly a primary object of the present invention to provide, for a squeeze-bottle of the above general type, a closure cap construction which will reliably prevent accumulation of the contents of the bottle onto the exterior thereof.

Another object of the present invention is to provide a closure cap of the character described which provides an improved leak-proof seal around the container mouth in both the open and closed position of the cap, and which, at the same time is easily displaceable between its open and closing position.

Another object of the present invention is to provide a closure cap construction which can be produced in an 3,229,657 Patented Nov. 30, 1965 economic molding operation and which can easily be assembled with the container itself.

In accordance with the invention, there is provided a closure and dispenser cap which is adapted to extend through the neck of a squeeze bottle, and is considerably longer than the neck 50 as to be slidable longitudinally between an elevated, operative position and a lowered, closed position. The closure cap has a hollow interior which communicates with the interior of the squeeze bottle through an open bottom end, and a discharge aperture located intermediate its ends for exposure when the closure cap is in raised position and for discharge of the liquid content of the bottle therethrough when the bottle is squeezed. The closure cap is formed with a series of annular sealing sections which engage the inner surface of the bottle neck and provide a sliding surface for the closure cap and liquid-tight and air-tight seals with the inner surface of the bottle neck, these sections being separated by alternate sections of lesser diameter than the bottle neck. An additional feature of the invention resides in the provision of one or more sharp edges below or above the discharge aperture, which edges act as a surface for the dripping of excess fluid away from the body of the closure cap to prevent leakage thereof onto the surface of the closure cap and bottle. A reservoir slot is provided adjacent each of the sharp edges to collect and retainexcess fluid remaining on the closure cap. 7

Additional objects and advantages of the invention will become apparent during the course of the following specification when taken in connection with the accompanying drawings, in which:

FIG. 1 is a front elevational view of closure cap made according to the present invention;

FIG. 2 is a longitudinal section taken along the line 2-4 of FIG. 1 in the direction of the arrows;

FIG. 3 is a transverse section taken along line 33 of FIG. 1;

FIG. 4 is an enlarged front elevational view of the closure cap shown in FIGS. 1-3, showing the closure cap mounted within the neck of a container, the container being shown fragmentarily and in section, and portions of the closure cap being broken away; and

FIG. 5 is an enlarged elevational view similar to FIG. 4, but with the closure cap in its raised position relative to the container and rotated about its central longitudinal axis.

Referring now to the drawings, it will be seen that the closure cap A of the present invention is adapted to be assembled with a squeeze-bottle B, which is fragmentarily illustrated in FIGS. 4 and 5, and both the closure cap A as well as the squeeze-bottle B are made of a suitable resilient and flexible plastic, such as polyethylene, for example. Moreover, the closure cap A has a one-piece construction and is molded in its entirety in a single operation, and the same is true for the squeeze-bottle B, so that the entire dispenser assembly includes but two elements.

The closure cap A has an elongated tubular body 10 which is provided with enlarged upper and lower ends, the enlarged upper end 12 forming a cap which projects radially from elongated member 10 at its upper end while the enlarged lower end 14 is adapted to act as a stop for limiting the upward movement of the closure cap, as will be presently described. Between its upper and lower enlarged

ends

12 and 14 the tubular body member 10 has a generally cylindrical configuration, and is sized for insertion within the neck 16 of the bottle B, as shown in FIGS. 4 and 5. In this mounted condition, the upper enlarged end 12 of the body 10 engages the upper surface 18 of the neck 16 to prevent downward movement of the closure cap past the lower closed position shown in FIG. 4 where the container B is provided with an air-tight and fluid-tight seal by the closure cap, as will be apparent from the description below. The enlarged lower end 14 of the body engages the bottom end 21 of the neck 16, as indicated in FIG. 5, to limit the upward movement of the closure cap to the upper open position thereof which is illustrated in FIG. 5.

As may be seen in FIG. 2, the elongated tubular body 10 has a hollow interior and an open bottom end 22 through which the hollow interior 20 communicates with the interior of the container B. In addition, the member 10 is formed, between its upper and lower ends, with a substantially radial discharge aperture 24. Thus, when the closure cap is in the upper open position of FIG. 5,'

the operator need only compress the bottle B to reduce the interior volume thereof and thus displace the contents upwardly through the open bottom end 22 into the hollow interior 20 and out through the discharge aperture 24 of the body 10, and the liquid will issue from the member 10 in a steady solid stream which can be readily directed to any desired location.

The upper enlarged end 12 of the body 10 includes a top wall 26 which closes off the top end of the hollow interior 20 of body 10, and which projects beyond the member 10, terminating at its outer periphery in a downweirdly-directed lip 28. This lip 28 may be knurled at its exterior surface so that the operator can conveniently grasp the closure cap for lifting and lowering the same between its closed and open positions. A plurality of reinforcing ribs 30, shown most clearly in FIG. 3, extend between and are formed integrally with the tubular body 10 and the lip 28 as well as with the bottom surface of upper wall 26 so that in this way the lip 28 is maintained rigid and will not yield when grasped by the operator. A portion of the lip 28 which is angularly aligned with the discharge aperture 24 is formed with a notch 32 to provide clearance for the stream of liquid issuing from the aperture 24. As the volume of the creamy liquid within the bottle B becomes lower during use, the user must incline the bottle angularly downward to an increasing extent in order to facilitate the discharge of the liquid content, such position being a downward inclination of approximately 45 from the vertical. In such position, notch 32 will provide clearance for the stream of liquid and will prevent the liquid from engaging the lip 28 to be undesirably deflected thereby. The top surface of upper wall 26 is also molded to define an index, in the form of an arrow 34 which is aligned with the discharge aperture 24 and enables the user to direct the stream of liquid in the properdirection.

It will be seen from FIG. 4 that in the lower closed position of the closure cap, the lower edges of the ribs engage the upper surface 18 of the bottle neck 16, acting as a stop to restrain further downward movement of said closure cap.

While the greater portion of the elongated tubular body 10 is made of a diameter appreciably less than the internal diameter of the bottle neck 16, the body 10 is formed with spaced annular bands or sections of greater diameter, these bands being sized to fit snugly within the bottle neck 16, having a sliding and sealing fit therewith. Thus, the elongated body 10 has molded on its outer surface a primary annular sealing section 40 of external diameter substantially equal to the inner diameter of bottle neck 16. The primary sealing section 40 engages the interior surface of neck 16 with a snug fit so as to provide a fluid-tight and air-tight seal therewith when the closure cap is in the closed position shown in FIG. 4. In addition, the section 40 provides a primary area of sliding contact when the closure cap is moved between its open and closed positions.

The body 10 is also formed with a secondary annular sealing section 54, spaced a short distance below the primary section 40, a lower annular sealing section 58 located adjacent the bottom end of body 10, and an upper annular sealing section 64 located at the top of body 10 immediately beneath and adjacent the ribs 30. All of these sealing sections $4, 58 and 64 are of substantially the same diameter as the primary sealing section 40, that is, they are sized to make a snug slide fit with the interior of neck 16 and form a liquid-tight and air-tight seal therewith.

Between the enlarged diameter seal-

ing sections

64, 40, 54 and 58, and spacing the same, are

respective body sections

42, 44 and 56, all of a reduced diameter to provide clearance between their outer surfaces and the inner surface of neck 16, as shown in FIG. 4.

The lower annular sealing section 58 terminates at its lower end in a bottom section 38 which forms the lower enlarged end 14 of the tubular body 10. The bottom section 38 tapers downwardly from an upper edge, which is of greater diameter than the sealing section 58, to a lower edge which is of lesser diameter than the reduced diameter "

body sections

42, 44 and 56. The tapered form of the bottom section 38, and the reduced diameter of its bottom end facilitates the introduction of the lower end of the closure cap into the bottle neck 16. The upper end of bottom section 38, being of enlarged diameter, forms a shoulder 37 with the lower sealing section 58.

The daimeter of the bottom section 38, in the region of the shoulder 37, is in excess of the inner diameter of neck 16. When the tapered bottom section 38 is inserted into the neck 16, and downward pressure is exerted thereon, the upper end of the bottom section 38 is compressed so that the shoulder 37 enters and slides down the inner surface of neck 16, and snaps outwardly to its which permits suflicient compression thereof to permit itsinsertion through the bottle neck 16.

Once inserted, the shoulder 17 acts as a stop by engaging the bottom surface 21 of neck 16, as shown in FIG;

5, to limit upward movement of the closure cap relative to the bottle and to define the fully extended position of the closure cap.

The discharge aperture 24 is located centrally within the primary annular sealing section 46. It will be observed in FIG. 2 that the tubular body 10 has an area of substantial wall thickness in the vicinity of the discharge aperture 24. The body 10 is formed with a relatively deep, elongated circumferential slot 48 in reduced diameter body section 44, in alignment with and immediately beneath the discharge aperture 24. Similarly, the body 10 is also formed with a deep, elongated circumferential slot 52 in the reduced diameter body section 44, in alignment with and immediately above the discharge aperture 24. The

slots

48 and 52 are, at their respective upper and lower ends, co-extensive with the edges of the primary annular sealing section 46, so as to provide relatively sharp and well-defined no-drip edges or

corners

46 and 50 below and above the discharge aperture 24.

In use of the assembly, the closure cap A is withdrawn to its extended position of FIG. 5, and the bottle B is tilted and squeezed so as to force the creamy liquid content thereof through the discharge aperture 24 and upon the hand of the user, for example. liquid tends to run down the surface of the closure cap and onto the bottle. closure cap A, however, when the bottle is held in an up right tilted position, the cream collects and drips 011 the sharp edge 46. Similarly, if the bottle is inverted, the creamy liquid will collect and drip off the sharp edge 50. Any excess liquid remaining on the exterior of the primary section 40 will flow into the slot 48 or slot 52 and collect therein. A considerable amount of liquid is capable of accumulating in either of the

slots

48 and 52, so as to avoid undesired flowing along the surface of the closure cap.

In such use, excess.

Because of the novel form of the In order to frictionally retain the closure cap in its lowered, closed position of FIG. 4, the closure cap is provided with .a projecting annular locking bead 60 of semicircular configuration, between the reduced diameter section 42 and the upper sealing section 64. The bottle neck 16 is provided with a complementary annular groove 62 located adjacent the upper end thereof, which is sized to receive the locking head 60. In the closed position of FIG. 4, the bead 60 snaps into the groove 62 to provide a releasable lock for the closure cap but does not provide a seal, so that it may be easily inserted and removed.

In the closed position of FIG. 4, a liquid-tight and airtight seal is provided for the closure cap at its top end by engagement of the upper annular sealing section 64 with the top inner surface of neck 16 immediately above the head 60. Another seal is provided by engagement of the primary annular sealing section 40 with the interior of neck 16, and a further seal is provided by the secondary annular sealing section 54 with the bottom end of the neck 16. The seal provided by primary section 40 is sufficient in itself, because of the relatively large width of section 40, to prevent flow of the liquid content between the closure cap 'body 10 and the inner surface of neck 16, in

case of accidental squeezing of the bottle when the closure cap is in its closed position, and also to prevent air from entering the interior of the body. The seal provided by the upper annular sealing section prevents a1r from entering the neck and contacting the liquid accumulated in the reservoir slot 52 so as to cause drying and caking thereof. The seal provided by the secondary sealing section 54 prevents liquid in the bottle B from reaching and filling the slot 48.

When the closure cap is raised from its closed position of FIG. 4 to its extended, operative position of FIG. 5, the primary and secondary

annular sections

40 and 54 slide upwardly along the inner surface of neck 16. Because these sections are not continuous with each other and are separated by sections of lesser diameter, the areas of sliding contact are relatively small and a relat1vely small frictional resistance is encountered 1n mov ng the closure cap. The secondary sealing section 54 is also tapered as shown to provide a small area of frictional contact and compensate for the long reg on of drag at the lower portion of the closure cap. This permits the closure cap to be manually operated with less effort than is required in conventional sliding closure caps.

As the closure cap moves upwardly, the pr mary sealing section 40 leaves the bottle neck 16, exposing the d1scharge aperture 24. The secondary sealing section 54 continues to serve as the sliding surface for the closure cap for a short distance, and just as top of the bottle neck 16, the lower annular sealing section 58 enters the bottle neck 16 and provides a sliding surface. In the fully-extended position of the closure cap, shown and the lower sealing section 58 is within the lower end of the bottle neck, providing a sliding surface and also providing a seal to prevent the liquid, under pressure, of the squeezed bottle, from flowing betweenthe closure cap and the bottle neck 16.

\Vhen the closure cap is lowered to its closed position of FIG. 4, the secondary sealing section 54 engages the inner surface of the bottle neck 16, wiping off any liquid which may have accumulated on the surface of said section 54. This liquid collects in the reduced diameter section 44, particularly in the slot 48 therein. Similarly a self-wiping action is performed by the primary sealing section 40, causing any liquid accumulated thereon to flow into the reduced diameter section 42 and the slot 52 therein. Such wiping action prevents accumulated liquid from gathering and caking at the top of the bottle neck, which has hitherto been an undesirable feature of slidetype closure caps.

It is apparent from the above description that the stopit approaches the i in FIG. 5, the primary and

secondary sealing sections

40 and 54 are locatedexternally of the neck 16 per A of the present invention can be readily molded in an inexpensive manner from plastic materials such as polyethylene, and is also capable of being eaisly assembled with the container B, while at the same time remaining reliably connected thereto since it cannot be easily pulled upwardly from the position shown in FIG. 5. Moreover, the stopper will effectively prevent any dripping of liquid onto the exterior of the bottle, even at the neck 16 thereof, while also maintaining any film at the interior surface of the neck 16 at a minimum thickness so that the tendency of the liquid to drip will be minimized.

Furthermore, because the outer atmosphere is maintained out of contact with the entire interior of the container, including the inner surface of the neck 16, there will be no caking of the liquid content at any part of the bottle or closure cap.
