FIG. 4
INVENTOR. William H. McKnight (fly/7.
ATTORNEY United States Patent 3,371,81 1 CONTAINER CLOSURE William H. McKnight, Corning, N.Y., assignor t0 Coring Glass Works, Corning, N.Y., a corporation of New ork Filed Nov. 20, 1964, Ser. No. 412,607 3 Claims. (Cl. 215--39) This invention relates to container closures and more particularly to a tape seal closure for hermetically sealing wide-mouth containers which may be repeatedly reclosed and reopened after the vacuum has once been released.
At the present time, container closures are being widely used in the packaging of food products. One method of packaging is to place suitably prepared food in a glass container and to seal with a closure. Proper subsequent treatment of the food filled container creates a vacuum within said container. In some presently available container closures, it is this vacuum alone by which the container closure is held in place to prevent spoilage of the food.
Consumer tests have shown that once the vacuum is released, this loosely fitting lid is not acceptable as a reclosure. It thus is necessary to add a mechanical lock to hold the closure in place when reclosure is desired. This lock may be in the form of a rolled edge of metal under a glass bead or suitable retaining lugs bearing against the sides of the container finish. A further disadvantage of prior closure cap devices is that bending, distortion, or cracking of the closure often occurs during removal so that the closures cannot be reapplied to the container.
Some prior art devices provide a centrally located hole in the closure. Prior to sealing the closure to the container a removable tape closes the hole. This method does not interfere with the ability of the closure to be held on the container by vacuum. In order to remove the closure, it is necessary to partially remove the tape covering said centrally located hole, thus releasing the vacuum. This same tape then acts as a handle to lift the closure from the container. One such device has no rim, lugs, or other mechanical interference fit with the glass finish. It can then be replaced as a loose lid to close the container but its disadvantage lies in the fact that there is no mechanical means of holding the lid in place once it has been removed. Another such device adds a mechanical lock to hold the closure in place. However, when this is done, the effort to remove the closure by pulling on the centrally located tape is too great and removal of the closure is very difficult.
The present invention not only alleviates the problem of removal heretofore encountered with known types of closures, but also provides a convenient easily-operable closure which is readily reclosable once the vacuum seal is broken. Basically my invention relates to a tape seal closure wherein a hole is located eccentrically, near the circumference of the closure. Such a location will not interfere with the vacuum release function of such hole. A fixed end of the tape is situated between the perimeter of the closure and the hole. Such location of the fixed end of the tape and of the hole will not interfere with the vacuum release function of the hole; the tape so located will provide a lever arm to aid in the closure removal. Thus a device is created which will allow a mechanical lock to hold the closure in place and at the same time provide a means of easy removal and reapplication.
It thus has been an object of the present invention to provide an improved, easily removable, closure for widemouthed containers.
A further object of the invention is to provide a closure cap which will not bend or crack during removal.
An additional object of the invention is to provide a low cost container closure.
A further object of the invention is to provide a closure with a tamper flag to indicate a loss of vacuum.
Other objects and advantages of the invention will be shown in the following detailed description of a preferred embodiment thereof as illustrated in the accompanying drawing in which:
FIG. 1 is a top plan view of the container closure with a vent and a tamper flag fitted tightly to the closure.
FIG. 2 is a fragmentary vertical section taken along line 2-2 of FIG. 1 illustrating the positionment of the closure on a container after the tamper tab has been lifted from the vent and the vacuum released.
FIG. 3 is a bottom plan view of another embodiment of the present invention as applied to a closure provided with retaining lugs.
FIG. 4 is a fragmentary vertical section taken along line 44 of FIG. 3 illustrating the positionment of a second embodiment of the closure after the tamper flag has been lifted from the vent and vacuum released.
Referring now to the drawing, a mouth defining neck portion of a container, such as a glass jar 8, is provided with an annular, outwardly-projecting beaded finish 10. A container closure 12 such as a cap or lid of any suitable plastic or non-corrosive sheet metal is formed with a substantially fiat, circular top portion or panel 14 which projects within the open upper end of the mouth defining neck portion of container 8.
Annular, gasket receiving channel 16 inclines upwardly and outwardly from the outer margin of the circular top portion 14. Gasket receiving channel 16 is bounded by gripping finish means 18 such as annular, downwardlydepending curvilinear beam section shown in FIG. 2, which is turned or rolled to conform to and grip beaded finish 10. Such procedure allows for the absorption of glass tolerances and any out of round conditions.
In order to hermetically seal the closure 12 to the container, when the container is filled, a suitable sealing ring or gasket 20 composed of an elastomeric material, such as rubber or the like, is applied to the inner surface of gasket receiving channel 16. The gasket cooperates with the gasket-receiving channel 16 and the container, and is compressed to form a seal by the impression of the glass into the elastomeric material of the sealing ring.
An aperture or vent 22 is formed in container closure 12. In a preferred embodiment, shown in FIGS. 1 and 2, the vent 22 is situated near the outer circumference of circular top panel 14.
A tamper flag or tab 24 which is partially removable is relatively aflix'ed to the upper surface of container closure 12. In a preferred embodiment tab 24 has a free'end 26 and a fixed end 28. The free end 26 merges into lateral extensions 30 of fixed end 28. The tamper flag 24 is made of a suitable non-corrosive material such as a sheet metal or thin plastic.
The fixed end of the tamper tab is positioned in a radial alignment with the vent 22 and adheres to the upper surface of the closure from the vicinity of the perimeter of said closure and inwardly to a point at least past the vent 22. A suitable adhesive is used to attach the tab to the upper surface of container closure 12. The adhesive exhibits the properties of low peel strength but high tensile strength. The tab is sufficiently attached to the container closure so that vent 22 is shut off from the atmosphere and a vacuum can exist inside the container.
To open the container, free end 26 is pulled away from the container closure and the adhesive peels such that the vacuum is released through vent 22. The fixed end is wider in an outwardly direction from vent 22 due to the lateral extensions 30. When this wider section is reached it becomes harder to peel tab 24 from closure 12 than it is to lift the closure from its engagement with the container. Thus the tab exhibits the dual function of releasing the vacuum through vent 22 when desired, 'and further acts as an aid to lifting the closure from the container.
It is within the course and scope of the present invention that the area of fixed end 28 may be varied to prevent complete removal of the tab from the closure. It is further within the course and scope of the present invention to use two types of adhesive; a low peel strength adhesive would be used in the vicinity of the vent and a high peel strength adhesive would be used in the area of the fixed end nearest the perimeter of the closure to prevent complete removal of the tab from the closure.
Once the tamper flag 24 is lifted it can never be pushed down again into complete contact with the upper surface of the container closure. Thus a prospective purchaser is made aware of the fact that the vacuum of the closure may be broken and spoilage of the contents of the container is possible.
A further embodiment of the present invention is shown in FIG. 3 wherein a press on type of closure is shown. This type of closure is adopted to be applied containers by forcing it down on the finish of the container. Such a procedure allows the absorption of large glass tolerances and out of round conditions.
In this embodiment a mouth defining neck portion of the container, such as a glass jar 37, is shown having an annular, outwardly-projecting beaded finish 39. A container closure 41 such as a cap or lid is applied to the container 37. Substantially flat, circular top panel or portion 43 is relatively inserted within the mouth defining neck portion of container 37. Annular, gasket-receiving channel 45 inclines upwardly and outwardly from the outer margin of the top portion 43. Annular, gasket receiving channel 45 is bounded by annular, downwardlydepending skirt portion 47. Means for gripping the container finish, such as peripherally-spaced, internal, closure retaining lugs 49 are formed in annular, downwardly depending skirt portion 47. Lugs deform on being applied to the glass to accommodate any out of round and tolerance variation of the glass finish. The lugs bear against the sides of the container finish to hold the cap in place. Since the lugs are flexible, the closure or cap may move upwardly without bending or cracking. A suitable sealing ring or gasket 51, composed of an elastomeric material, such as rubber or the like, is applied to the inner surface of gasket receiving channel 45.
Vent 22 performs the same function and is situated in' the same location in container closure 41 as in container closure 12. Tamper flag 24 of closure 41 is attached and adheres in the same manner and is located in a similar position as it was in container closure 12.
In order to facilitate grasping the tamper flag 24, as it is being partially removed and used to lift the closure from the container, a ribbed portion 53 may be provided at the outer extremity free end 26.
It is within the true course and scope of the present invention that tab 24 may be applied to any known configuration of vacuum closure which is provided with a suitable aperture, such as 22.
Thus this invention is able to provide 'an improved, tape-seal closure from vacuum containers. Partial removal of the tape covering a hole which is located eccentrically near the circumference of the closure releases the vacuum. Suitable configuration and suitable application of adhesive or adhesives prevents this same tape from being completely removed from the closure and thus the tape acts as a handle to lift the closure from the container. Since the fixed end of the tape is permanently secured to the closure adjacent one side of its circumference, a lever arm substantially equal to the diameter of the closure is in effect provided for easily facilitating the removal of the closure. That is, as the closure is lifted off of the container by lifting the pull tab attached to one side of the closure adjacent its circumference, the closure is pivoted about the neck finish of the container at the opposite side of the closure. Such ease of removal derived by this mechanical advantage was not possible with the known types of vented closures. Means for gripping the container finish hold the closure in place during the initial vacuum period and during subsequent reclosure operations.
Reclosure may be maintained by a curvilinear beam section or retaining lugs which mechanically grip the jar finish. The tamper flag, once lifted, can never be pushed down completely flat again and serves as a warning to a consumer of the possible contamination of the contents. This invention thus provides an improved easily-opened closure which not only hermetically seals the container but which may be repeatedly reclosed and reopened.
Although the forms of embodiment of the present invention as disclosed herein embody preferred forms, it is to be understood that other forms might be adopted, without departing from the true spirit and scope of the appended claims.
I claim:
1. An improved closure for open mouth containers which are vacuum packed and hermetically sealed and which may be readily reclosed and reopened once the vacuum is broken which comprises, a circular top panel projectable within a mouth-defining neck portion of a container, an annular gasket-receiving channel inclined outwardly and upwardly from the outer mar-gin of the said top panel for receiving said mouth-defining neck portion of such container, means for gripping an outer finish H of said neck portion, an annular sealing gasket positioned within said annular gasket-receiving channel, a vent penetrating the top panel of said closure, .a partially removable tab permanently secured to the upper surface of said closure adjacent the perimeter thereof and extending inwardly to cover said vent and prevent loss of vacuum until such time as said tab is partially removed, and said tab being permanently fixed at its outer extremity adjacent the perimeter with a high peel strength adhesive and semi-permanently affixed inwardly thereof by a low peel strength adhesive.
2. An improved closure as defined in claim 1 wherein the said means for gripping the outer finish is an annular downwardly-depending curvilinear beam-section bounding said gasket-receiving channel which conforms to and grips said gasket-receiving channel which conforms to and grips said finish.
