Abstract
Description
- The present invention is directed to a flip-top dispensing closure. More particularly, the invention is directed to a flip-top dispensing closure having a pour spout that is open at a region where a base portion is hingedly connected to a cap portion.
- Many consumer products such as liquid laundry detergent are packaged in containers with flip-top dispensing closures and continue to be popular with consumers.
- Typically, flip top closures have round orifices with round plugs that seal the orifice when the top is closed and may have pour spouts that are also round and encircle the round orifice. The sale of such products in containers having flip-top closures has enhanced the consumers experience in the use of many consumer products, thus helping to increase their popularity. However, such conventional flip-top closures can be messy to use and do not pour well with liquids of various viscosities, especially liquids with high viscosity.
- While many consumer products come in the form of low viscosity liquids, new forms of consumer products having higher viscosities, such as laundry detergents in the form of gels have also been developed. It is of increasing interest, therefore, to develop a convenient flip-top closure for neatly and efficiently dispensing products such as liquid laundry detergent, as well as other more viscous flowable product forms such as gels.
- Other drawbacks associated with conventional flip-top closures are that they often drip as they typically don't have an anti drip lip. Also, the pouring opening is limited in size in flip-top closures having a pouring spout since the plug for sealing the pouring opening must clear the pour spout in order for the lid to close.
- An object of the present invention to provide a flip-top closure that neatly and efficiently dispenses products such as liquid laundry detergent, as well as other more viscous flowable product forms such as gels.
- It is another object of the present invention to provide a flip top closure with a pour spout that has a pour opening that is less limited in size due to a sealing plug than current flip top closures having a pour spout.
- Other objects of the present invention will become apparent to those skilled in the art by reference to the specification.
- Numerous flip-top closures have been disclosed in the patent literature. Such closures are illustrated in Anderson U.S. Pat. No. 6,530,493; Wagner U.S. Pat. No. 6,481,588; Smith et al. U.S. Pat. No. 6,460,712; Randall et al. U.S. Pat. No. 6,382,476; Wilson U.S. Pat. No. 5,271,536; Beck et al. U.S. Pat. No. 4,638,916; Gach U.S. Pat. No. 4,807,769; Odet et al. U.S. Pat. No. 5,141,138; Poore et al. U.S. Pat. No. 4,782,964;
- The objects of the present invention are achieved in a flip-top closure having a pour spout that is less than 360° and an anti drip lip.
- In a first aspect, the present invention is directed to a flip-top closure assembly for affixing atop a neck of a container comprising:
-
- a) a base portion; and
- b) a cap portion that is hingedly connected to the base portion;
wherein the base portion has a peripheral skirt for engagement with the open neck of a container, a floor extending inwardly from atop the skirt and having an opening therein that defines a pour opening, and a pour spout ascending from an inward portion of the floor, wherein the spout extends only partially around the pour opening thereby leaving a portion of the pour opening where there is no spout and wherein the portion of the pour opening where there is no spout being where the cap portion is hingedly connected to the base portion, and wherein the cap portion has an open and close position, a peripheral skirt, a ceiling extending inwardly from atop of the skirt, and a cylindrical rim extending downward from the ceiling, wherein the rim forms a seal with the base portion floor when the cap is in a close position.
- In a second aspect, the present invention is directed to the flip-top closure of the first aspect incorporated into a container containing a flowable product.
- All numerical ranges and percentages in this specification and claims are intended to be modified by the term about.
- As used herein, the term “comprising” means that a specified material or element is present, optionally together a further material or element, and includes including, made up of, composed of, consisting and/or consisting essentially of.
- For a more complete understanding of the above and other features and advantages of the invention, reference should be made to the following detailed description of preferred embodiments and to the accompanying drawings.

FIG. 1 is a perspective view of a flip-top closure according to the invention with the cap in a closed position. -
FIG. 2 is a perspective view of a flip-top closure according to the invention with the cap in an open position. -
FIG. 3 is a cross-section view along lines 3-3 ofFIG. 2 of a flip-top closure according to the invention. -
FIG. 4 is a perspective view of a container with a flip-top closure according to the invention. - Referring now particularly to the drawings, a flip-top closure of the invention will be described with respect to a specific embodiment.
- Flip-
top closure 14 includes abase portion 40 and acap portion 60. The base portion includesperipheral skirt 42,floor 44, andpour spout 46.Cap portion 60 includesperipheral skirt 62,ceiling 64, andcylindrical rim 66. -
Cap portion 60 is hingedly connected tobase portion 40 by mean ofhinge 80. Preferably,hinge 80 is integrally formed withbase portion 40 andcap portion 60 in a unitary structure. The illustrated living hinge is a conventional type described in U.S. Pat. No. 5,271,536, the disclosure of which is incorporated by reference herein. Other hinge structures may be employed, including a snap-action hinge as described in U.S. Pat. No. 4,403,712, the disclosure of which is incorporated by reference herein. -
Floor 44 ofbase portion 40 extends inwardly from the top ofperipheral skirt 42.Floor 44 has an opening that defines a pour opening 50. Pourspout 46 ascends from an inward portion of thefloor 44. Pourspout 46 is a partial pour spout meaning thatspout 46 does not completely encircle the pour opening 50 infloor 44. Accordingly, pourspout 46 has anopen region 52.Open region 52 is in the region where thecap portion 60 is hingedly connected to thebase portion 40. As a result, the pourspout 46 extends around the edge of pour opening 50 less then 360°. Preferably, the pour spout extends around the edge of pour opening 50 less than 300°, and more preferably less than 270°, and even more preferably less than 240°. Additionally, pourspout 46 has ananti-drip lip 56. Theopen region 52 inspout 46 enables the flip top closure of the present invention to have a larger pour opening with a spout as the open region enables thecylindrical rim 66 on the cap to have enough clearance for the cap to close. Without this opening, the size of the pour opening and spout would be more limited as the cylindrical rim would not clear the spout in the region where the cap portion and base portion are hinged, thereby interfering with placing the cap in the closed position. -
Cap portion 60 is adapted to be moved between an open position (as illustrated inFIG. 2 ) and a close position (as illustrated inFIG. 1 ) in which thecap portion 60 is sealingly engaged with thebase portion 40. Thecap portion 60 has aperipheral skirt 62, aceiling 64 extending inwardly from the top ofperipheral skirt 62, and acylindrical rim 66 extending downward from theceiling 64. Cylindrical rim 66 is sized accordingly so that it fits securely within pour opening 50 infloor 44, such that thecylindrical rim 66 acts as a plug and forms a releasable seal withfloor 44. The seal is formed with thebase floor 44 and is formed inward of the pourspout 46. Accordingly, when the cap is closed the pour spout is outward of the cylindrical rim that forms the releasable seal with thebase floor 44. Preferably,cylindrical rim 66 is sized such that it also touches the inside surface 54 of the pourspout 46 ascap portion 60 is moved from the open position to the closed position. This enables thecylindrical rim 66 to sweep the inside surface 54 of the pourspout 46, thereby cleaning the pour spout when thecap portion 60 is moved into the closed position. - The cap portion may have a second cylindrical rim (not shown) extending downwardly from the
ceiling 64 that is between thecylindrical rim 66 and theperipheral skirt 62. This second rim may be positioned so that thespout 46 fits snugly between the firstcylindrical rim 66 and the second cylindrical rim, such that it assist in keeping the cap in the closed position. In this embodiment, a greater lift force may be needed to open the cap. This can be useful to prevent the bottle from opening accidentally and spilling the contents of the bottle or making the bottle more difficult to open as may be desired for a child-proof embodiment. The second cylindrical rim need not be a complete cylinder, but can simply be a clip portion that is positioned to embrace the spout. - It will be appreciated that while the
floor 44 of the base portion is described as extending inwardly from the top ifperipheral skirt 42, thefloor 44 may extend inwardly from any portion, not necessarily the top, ofperipheral skirt 42 such as midway upperipheral skirt 42. Likewise, theceiling 64 of the cap portion is described as extending inwardly from the top ofperipheral skirt 62. However, the ceiling may extend inwardly from any portion, not necessarily the top, ofperipheral skirt 62. - Referring now to
FIG. 4 ,package 10 comprises acontainer 12 and flip-top closure 14.Container 12 includes acontainer body 16 and an upper end with acylindrical neck 18 which includesfinish 20 at its upper end. - The base portion is adapted for engagement with the
finish 20 of the neck of the container. Thecylindrical neck 18 ofcontainer 12 may be threaded withexternal thread 22 to mate with internal thread 48 (as shown inFIG. 3 ) onperipheral skirt 42. Alternatively, the flip-top closure 14 may engage the cylindrical neck of the container by other known means such as by snap-on means. -
Base portion 40,cap portion 60 and hinge 80 are preferably injection molded from a thermoplastic material compatible with the container material and contents. -
Container 12 and flip-top closure 14 may be mono-layer or multi-layer and may be made of HDPE, PP, PVC, PET, POLYCARBONATE or acrylic or nitrite base resins, and preferably contains a minimum of 25% PCR. - It should be understood of course that the specific forms of the invention herein illustrated and described are intended to be representative only as certain changes may be made therein without departing from the clear teachings of the disclosure. Accordingly, reference should be made to the following appended claims in determining the full scope of the invention.
