This invention relates generally to clips for binding bags and similar packaging in a closed position.
Many food items are sold in a bag which cannot readily be closed with an airtight seal once it is opened. A spring-loaded clip works well to enclose the opened end of the bag by gathering the open portion together and crimping it with the clip. Such a manner of closing is beneficial but generally not air tight. Therefore, once the bag has been opened it is often useful to know how long it has been since the bag was first opened. Presently, neither the clip nor other devices are able to both seal the bag and provide an indication of the date that the bag was first opened.
A bag clip comprises a pair of opposing jaws configured for resilient movement between an open position in which the jaws are apart from one another to receive a bag or other item to be grasped, and a closed position in which the jaws are adjacent one another to clamp onto the bag or other item and thereby hold it in a closed position. The preferred bag clip with date wheel includes a pair of opposing clip plates resiliently joined to one another such as by a spring that biases the plates toward one another. The plates may be pried apart to create a space for receiving an opening of a bag (or other item to be clipped together), and then the biasing force urges the clip plates closed to likewise close the mouth of the bag.
In one version of the invention, the opposing clip plates are pivotally connected to one another, with a coil spring biasing the plates into a closed position.
A preferred bag clip further includes an indicator wheel which may be in the form of a date indicator, which in one example of the invention is configured as a wheel with a plurality of date-based indicators. A pointer on one of the clip plates points to a particular date on the date wheel, which in one preferred use of the invention will correspond to a date on which the bag was first opened and the clip was first attached.
In some versions of the invention more than one indicator or date wheel may be attached to the clip, for example including a first date indicator for a particular month and a second date indicator for a particular date within the month.
Preferred and alternative examples of the present invention are described in detail below with reference to the following drawings:
A preferred bag clip 10 is illustrated in the accompanying figures. As illustrated for example in
Most preferably, the clip 10 is formed with a first clip plate 20 and an opposing second clip plate 30. Each of the first and second clip plates in the illustrated version is configured with a wide base or jaw which tapers upward to an upper end configured for grasping by a user. Each of the first and second clip plates 20, 30 further includes an outward facing side 23, 33 and an inward facing side 24, 34 (see
Although the term clip “plate” is used, it should be understood that neither of the clip plates need be planar or have any particular size such as that of a plate, and that alternate shapes may be used in different versions of the invention.
An axle 60 is positioned to receive holes formed through distal ends of each of the standoffs so that the standoffs, and therefore the clip plates, are attached to the axle for pivotal movement about the axle. As illustrated, and best seen in the side view of
A spring 80 is attached to the axle or the clip plates in a manner that urges the upper ends of the clip plates apart from one another, and the bases of the clip plates toward one another. In the illustrated version, the coil spring 80 is provided in which the coil spring is carried on the axle 60, with the axle 60 extending through the passageway formed in the center of the coil spring. As best seen in
At least one of the clip plates includes an indicator that is preferably in the form of a date indicator that may be adjusted by a user to indicate a day or date such as the date the bag was first opened or the date the clip was first attached to the bag. In one version, the clip includes a date indicator including labels corresponding to the days of the week, or the days of the month. In some versions, the clip includes a date indicator including the months of the year in addition to the days of the month, and most preferably the date indicator includes multiple date wheels or other settable indicators in such a version.
In accordance with a preferred version, the upper ends of each of the clip plates 20, 30 includes a wheel 40, 50 mounted on the clip plate for rotational movement of the wheel, with the wheel lying in the same plane defined by its respective clip plate. In a preferred version, each wheel is mounted on a respective clip plate such that at least a portion of the wheel extends beyond an outermost edge of the clip plate. Most preferably, a portion of each wheel extends beyond and above the topmost edge of each clip plate.
As best seen in
The outer perimeter of each wheel is also preferably formed with outwardly radiating teeth to provide a better grip for rotation by a user. In some versions, the clip plate may include a mating tooth to provide further frictional resistance of the rotation of the wheel, in which the mating tooth extends from a location on the clip plate and into a channel formed between adjacent teeth on the wheel.
In one example of the invention, the upper portion of each clip plate further includes a circular recess (e.g., 91, best seen in
Each wheel preferably includes a series of indicators 51 (see
The second wheel 50 includes numbers provided about the perimeter corresponding to days within a month. Thus, in the illustrated version the second wheel includes 31 separate indicators oriented around the perimeter of the wheel. In some versions each separate indicator may be in the form of a distinct number, while in other versions the indicators may include only a subset of the numbers with dots or other characters provided between the specific numbers. As with the month indicator, the date wheel may also include a category indicator with a category title indicating that the wheel corresponds to a particular date.
In the version of the invention having a date wheel and a month wheel, a user may attach the bag clip to a bag in order to seal the bag, and then rotate the month and date wheels to positions in which the date and month indicators for the appropriate date and month are both adjacent to the pointer on the respective sides of the clip.
Optionally, as shown in
Within the recess (e.g., 91) formed in each clip plate, at least one raised projection 92, 95 is formed and positioned to be received within one of the indentations. In a preferred version as illustrated, the raised projection is configured in a downwardly-directed V-shape, with a cutout surrounding the lower portion of the V. In this fashion, the projection is provided on a somewhat flexible V-shaped tongue that is capable of flexing into and out of the indentations 90 as the wheel is turned.
As the wheel is rotated, a certain amount of force is required to cause the indentation to separate from the projection so that the projection may slip into the adjacent indentation. This arrangement thereby prevents the wheel from rotating unless intentionally rotated by a user.
While the wheels are described above as having date and month indicators, in other versions of the invention the wheels may have other indicators corresponding to a plurality of attributes that a user may specify.
In a version of the invention having more than one wheel, at least one wheel may be incorporated into each one of the two clip plates, such as illustrated in
Most preferably, the pair of date wheels are concentrically attached, with a first one of the date wheels 140 being larger than the second date wheel 150, and each of the first and second date wheels having a center lying in a common axis. In the illustrated example, the first date wheel 140 includes a plurality of indicators 141 extending from 1 to 31, thereby indicating a day of the month corresponding to the indicator most closely adjacent the pointer 170. The second date wheel 150 includes a plurality of indicators 151 extending from 1 to 12, thereby indicating a month of the year. As with the version described above, the wheels may include words (such as the names of the months) or other indicators other than numbers.
While the preferred embodiment of the invention has been illustrated and described, as noted above, many changes can be made without departing from the spirit and scope of the invention. Accordingly, the scope of the invention is not limited by the disclosure of the preferred embodiment. Instead, the invention should be determined entirely by reference to the claims that follow.
