Description

FIELD OF DISCLOSURE

The present invention relates to the field of receptacles for food items and, more particularly, to a receptacle for disposing popcorn hulls, un-popped popcorn kernels, and seed shells.

BACKGROUND

Popcorn is a popular snack for people of all ages. Most often, popcorn is associated with movie going and is also often enjoyed at home when watching a movie or show on a home television. Having a bag or bowl of popcorn is part of the movie experience. However, that experience can be dimmed when an un-popped kernel or a hull enters the mouth. For some individuals, one or both can be an unpleasant feature to consume and have in the mouth.

Popcorn is made of dried corn kernels with tough shells that are heated until the steam created inside causes them to pop into the white fluffy edible food. However, because of that tough shell or hull, popcorn still has the thin remains of hull at the center of the piece. The hull is almost like a thin sharp bit that can cause irritation in several ways including and not limited to getting stuck between the teeth and gums, getting caught between the teeth, and getting stuck in the throat and causing a bout of coughing. An un-popped kernel can also be an offending piece in the mouth because it is a hard piece to bite down on and in some cases may cause a damaged tooth such as a cracked or broken tooth.

For these reasons, some people will spit out the hulls and the un-popped kernels. Most often these end up on the floor, back into the popcorn bag or bowl, or into a hand. Neither one of these options is ideal. A similar situation arises when eating seeds which are presented in their shells, such as sunflower seeds. Most often these shells are spat out into a bag or bowl or the ground. Spitting out the hulls, un-popped kernels, and the shells of seeds is not only unsightly but is also unhygienic as germs are dispersed from an individual’s mouth into the air. This is especially true for venues such as sports stadiums, arenas, and movie theaters. The standard practice has never been addressed for these crowded venues, while the germs are spread, and a mess is created on the ground next to another person(s). Existing devices and systems for providing a disposal means are unable to fully provide an easy means and are often overly complex.

Accordingly, there still is an unsolved need for neatly and hygienically disposing of unwanted food items in an individual’s mouth that may address these and other existing issues.

SUMMARY

One or more embodiments are provided below for a receptacle that allows an individual to consume popcorn, seeds, and other food items with shells, and then neatly and hygienically dispose of the hulls, un-popped kernels, and shells. The receptacle is designed to house the unwanted waste, wherein the receptacle can be attached to another container such as a bowl or a bucket that contains the edible item. For example, the receptacle may be attached to a popcorn bucket. The receptacle comprises a receiving unit and a collection unit, respectively. The receiving unit is adapted such that an individual’s mouth may be placed relatively close to the receiving unit to spit out any undesired bits from the mouth when consuming popcorn or seeds with shells. The receiving unit may also be adapted to encourage any discarded items to travel to the collection unit which is connected to the receiving unit The collection unit of the receptacle is designed to house the discarded waste. The receptacle also includes an attachment element allowing the receptacle to be connected to a bucket or bag containing an item of food to be consumed (e.g., popcorn bag).

In one non-limiting embodiment, the receptacle is fashioned from paper and is provided in a folded state in a bag which has an adhesive seal and backing that can be adhered to a side of a bucket or bag. After use, the receptacle can be folded back into the bag to contain the refuse and disposed with the bucket.

According to a second non-limiting embodiment, the receptacle is reusable and fashioned from a sturdier material. The receptacle includes a clip allowing it to be attached to a bucket or bowl. After use, the receptacle can be cleaned and ready for the next use.

According to these non-limiting embodiments, the receptacle provides a sanitary way to dispose of unwanted food waste from the mouth. The receptacle self-contains the spread of germs to reduce infection as a user spits the unwanted food items directly into the receptacle. Additionally, the receptacle allows unwanted food waste to be disposed of appropriately instead of on the ground creating a mess and filth.

Other aspects and advantages of the invention will be apparent from the following description and the appended claims.

The present disclosure is generally drawn to various embodiments for a receptacle that provides for a neat and hygienic way to discard popcorn hulls, un-popped kernels, and seed shells that an individual would normally spit out while consuming popcorn or seeds. In particular, the one or more embodiments of a receptacle make it possible for the receptacle to attach to a bag or a bucket for a food item, such as popcorn. Accordingly, a consumer can spit any inedible or undesired bits discretely into the receptacle. This is advantageous as many people will either spit out the bits onto the ground, back into the bag, a napkin, or swallow the undesired bit. The embodiments proved herein may be used with multiple bags and buckets. Further details are provided below with reference to the figures.

Turning to the figures, FIGS. 1-6 are an illustration of a non-limiting embodiment of a receptacle 100, which is an example of a disposable receptacle for receiving the inedible bits of popcorn and seeds in accordance with a non-limiting embodiment of the present invention. The receptacle 100 described in this embodiment may be useful in a commercial venue, such as a movie theater, sports, arena, music arena, and other venues where food items such as popcorn and seeds may be served. The idea has significance for those places where the receptacle 100 may not ideally be reusable, but where it is intended to be discarded after use and may be recycled or is biodegradable. As discussed above, the receptacle 100 may be defined as having an interior space which is adapted for receiving inedible bits of popcorn and seeds that may be directly spat out into the receptacle 100 from a consumer’s mouth. FIG. 1 illustrates a perspective view of the receptacle 100 and is shown to comprise of a receiving unit 110 and a collection unit 120. The receiving unit 110 and the collection unit 120 are seamlessly connected to each other such that the discarded bits from a consumer’s mouth move into the collection unit 120 from the receiving unit 110. The receptacle 100 may generally be used with a bag or other container from which a consumer may consume an edible snack, such as popcorn or sunflower seeds. FIG. 2 illustrates that the receptacle 100 of the present disclosure may preferably be provided in its own bag, such as a bag 300. The bag 300 has an adhesive backing that allows the bag 300 to be attached to a receptacle 500, as shown in FIG. 4. This allows for ease of use when an inedible bit needs to be spat out. The receptacle 100 may be preferably fashioned from a fibrous material that may be used to make paper and is disposable, biodegradable, or generally eco-friendly. Some examples of a such materials include, and are not limited to, tree fiber, bamboo, cork, cotton, hemp, mulberry, and other fibrous material that can be used to make paper. It is to be understood that the receptacle 100 may also be fashioned from material that is recyclable.

The receiving unit 110 is constructed to permit an easy and hygienic means of spitting into the receptacle 100. Additionally, the receiving unit 110 is also intended to make the act of spitting into the receptacle 100 a bit more discrete. To permit an easy and hygienic means of spitting into the receptacle 100, the receiving unit 110 may have a funnel shape defined by a wider upper end 111 at the opening for a mouth and which depends downward toward a narrower lower end 113 that integrates to the collection unit 120. The advantage of the funnel shaped receiving unit 110 is such that the wider upper end 111 with the narrower lower end 113 helps contain any spray that exits an individual’s mouth when spitting into the receiving unit 110. Another advantage of the funnel shaped receiving unit 110 is also that it allows for discreetly spitting out any inedible bits by placing the mouth close to or within the receiving unit 110. It is to be understood that any other shape that offers discreetness and maintains a hygienic environment by containing the spray exiting an individual’s mouth when spitting out the inedible bits is within the description of the present invention.

Referring to FIGS. 1, and 4 to 6, the receiving unit 110 of the receptacle 100 is shown to be closed at a top by a sleeve 112 prior to use. Specifically, the upper end 111 of the receptacle is closed by the sleeve 112. The receptacle 100 also comprises of a toothpick 114 which is disposed within the sleeve 112. The sleeve 112 is tubular shaped and dimensioned to fit the toothpick 114 snugly. The toothpick 114 and the sleeve 112 close the top end of the receiving unit 110. The toothpick 114 is provided to help reach difficult places in a consumer’s mouth to remove unwanted particles. As shown in the illustration, each end of the toothpick 114 extends out of the sleeve on their respective ends. This makes it easier for a consumer to pull out the toothpick 114 when needed. As best shown in FIG. 5, the sleeve 112 is shown to have a perforated end 116 that connects to the receiving unit 110, and a consumer would remove the sleeve 112 by tearing at the perforated end 116 to unseal the receiving unit 110. As best shown in FIG. 6, the consumer may pinch sides of the unsealed receiving unit 110 to open the upper end 111 into the funnel shape to arrange the receptacle 100 for receiving any debris being spat out.

The collection unit 120 forms an enclosed space that has an open end 121 and a closed end 123. The collection unit 120 is connected to the lower end 113 of the receiving unit 110, which is opposite the upper end 111. Specifically, the open end 121 is connected to the lower end 113 of the receiving unit 110. The closed end of the collection unit 120 is, as the name suggests, closed to contain the debris spat or blown out by a consumer. The funnel shape of the receiving unit 110 will direct particles down into the collection unit 120. As shown in FIG. 2, the collection unit 120 has a length which is folded. Additionally, the receptacle 100 is also folded at the perforated end 116 allowing the receptacle 100 to be stored within the provided bag 300. The length of the collection unit 120 is such that once the receptacle 100 is removed from within the bag 300 and unfolded, the unfolded length of the collection unit 120 can partially fit within a pocket created by the opened bag 300. It is also to be understood that the length of the collection unit 120 may also fit fully within the pocket of the opened bag 300.

As described above, the receptacle 100 is provided in the bag 300. Referring to FIGS. 2 and 3, the bag has a paper backing 310 which exposes an adhesive backing on the bag 300. The bag 300 can then be adhered to a bag or bucket, such as the bucket 500 shown in FIGS. 3 and 4. The bag 300 also has a seal at a top end 302 of the bag 300 which can be opened to remove the receptacle 100. Additionally, the bag 300 can be resealed at the top end 302. For example, once the receptacle 100 has been used, the consumer can fold the receptacle 100 back into the bag 300 and seal the bag 300 to contain any waste.

To use, a consumer would pick up the bag 300 with the receptacle 100 from a condiments station. The consumer would remove the paper backing 310 to expose the adhesive back of the bag 300 and place the adhesive back against the side of a bucket/bag 500 with a food item. The bag 300 would be placed upright so the top end 302 of the bag 300 is facing upward. To remove the receptacle 100, the bag 300 is opened by unsealing the top end 302. The receptacle 100 is pulled out and unfolded. The receptacle unit 120 is placed back into the bag with the closed end 123 at a bottom of the bag. The sleeve 112 is removed from the receiving unit 110 by tearing at the perforated end 116. The sleeve 112 with the toothpick 114 may be placed back into the bag for later use, if needed. The receiving unit 110 is fully opened by pressing on the sides of the upper end 111. Generally, the receptacle 100 is faced toward the consumer, so the consumer can place their face close to the receiving unit 110 to spit or blow out and unwanted bits in the mouth to prevent or reduce contamination. The toothpick 114 may be accessed from the bag 300 to remove any stuck particles. The receptacle 100 can be folded back into the bag 300 to discard.

FIGS. 7 to 12 illustrate a non-limiting embodiment of a receptacle 200, which is an example of a reusable receptacle for receiving the inedible bits of popcorn and seeds in accordance with a non-limiting embodiment of the present invention. The receptacle 200 described in this embodiment may be useful in a domestic setting, such as at home where a consumer would prefer to have a reusable receptacle that can be cleaned after each use and reused. The receptacle 200 may generally be used with a bucket, a bowl, or any other receptacle that can be used by a consumer to carry an edible snack, such as popcorn or sunflower seeds. The receptacle type that can be used with the receptacle 200 will collectively be referred to as a bucket 500 (see FIG. 10). FIGS. 7, 8, and 9 illustrates a perspective view, a side view, and a top side perspective view of the receptacle 200, respectively. The receptacle is shown to comprise of a receiving unit 210 and a collection unit 220. The receiving unit 210 and the collection unit 220 are connected to each other such that the discarded bits from a consumer’s mouth move into the collection unit 220 from the receiving unit 210.

It is to be understood that the receptacle 100 may also be fashioned from material that is recyclable.

The receiving unit 210 is connected to the collection unit 220. In the one or more non-limiting embodiments shown, the receiving unit 210 and the collection unit 220 may be integrated together such that the receiving unit 210 and the collection unit 220 are one piece or in other words are configured as a single piece. In alternate embodiments, the receiving unit 210 and the collection unit 220 may be two separate pieces that are removably adjoined together and can be separable after use to clean and store, if desired.

Like the above embodiment of receptacle 100, the receiving unit 210 of receptacle 200 is open and permits an easy access to spit out any inedible bits which are directed toward the collection unit 220. To permit an easy and hygienic means of spitting into the receptacle 200, the receiving unit 210 of the receptacle 200 may also have a funnel shape defined by a wider upper lip 211 at the opening for a mouth which depends downward toward a narrower bottom end 213 that connects to the collection unit 220. The advantage of the funnel shaped receiving unit 210 is the same as described above in the embodiment for the disposable receptacle 100, which is that the wider upper lip 211 with the narrower bottom end 213 helps contain any spray that exits an individual’s mouth when spitting into the receiving unit 210 and directs the bits toward the collection unit 220. Another advantage discussed above, is that the funnel shaped receiving unit 210 also that allows for discreetly spitting out any inedible bits by placing the mouth close to or within the receiving unit 210. It is to be understood that any other shape that directs the bits into the collection unit 220, offers discreetness, and maintains a hygienic environment by containing the spray exiting an individual’s mouth when spitting out the inedible bits is within the description of the present invention.

The collection unit 220 is connected to the narrower bottom end 213 of the receiving unit 210. In one or more embodiments, the collection unit 220 is tubular shaped and provides an interior space for collecting the inedible bits that are spat out by an individual. The collection unit 220 has a first end 221 and an opposing second end 223. The first end 221 is connected to the narrower bottom end 213 of the receiving unit 210. As shown in the figures, the collection unit 220 appears to have a circular cross section. It is to be understood that the collection unit 220 may have any cross-sectional shape including and not limited to an oval, a rectangle, a triangle, a trapezoid, and a polygon.
