Snap Container for Pre-Portioned Product and Related Methods

Abstract

A container for packaging a pre-portioned amount of liquid or dry product is provided that includes a one-piece outer casing defining an interior reservoir. The outer casing has a cylindrical shell that is closed at one end by a rounded tip and open at the opposing end with an open circular outer edge/rim defining a mouth. To fill the container, the product is introduced through the mouth into the interior reservoir; then opposing edges of the rim are compressed together and sealed with heat to create an elongated seal having two opposing ends. Multiple types of elongated seals are provided. In one aspect the outer casing is formed unitarily of a plastic resin. To open the container, the consumer squeezes the two opposing seal ends/termini toward each other; this deforms the elongated seal and causes the seal to snap open, which allows access to the product.

DETAILED DESCRIPTION OF THE INVENTION

[0063] Shown throughout the figures, the present invention is directed toward a one-piece container for packaging a pre-portioned amount of liquid or dry product, toward methods of packing, sealing, and accessing the product, and toward a machine designed for sealing the container. The container is configured to be manually snapped open to allow access to the enclosed product so it can be accessed and dispensed.

[0064] The snap container, shown generally as reference number 100, is illustrated in accordance with embodiments of the present invention in FIGS. 1-7 (which illustrate a sealed container with a T-shaped seal), FIGS. 8-14 (which illustrate a sealed container with a crimped seal), FIGS. 15-19 (which illustrate a container before sealing), and FIGS. 20-21 (which illustrate a container being snapped open). As shown, the snap container 100 comprises a one-piece outer casing 150 that forms the outer boundary surrounding an interior reservoir 105 (FIG. 17). The outer casing 150 includes a cylindrical shell or body 130 with a first end and an opposing second end, a closed rounded tip 120 disposed at the first end of the cylindrical body 130, and a rim 140 disposed at the second end. The rim 140 forms an open mouth that provides an entrance to the interior reservoir 105.

[0065] The closed rounded tip 120 is preferably not planar or squared off but has the shape of a mound having a central apex 125. The transition 135 between the cylindrical body 130 and the closed rounded tip 120 is preferably smooth.

[0066] When the container 100 is positioned with the closed rounded tip 120 oriented downwardly, the rim 140 of the outer casing 150 will be oriented upwardly. Before sealing, the rim 140 comprises a circular open edge that forms a peripheral border or mouth at the entrance to the interior reservoir 105 into which the product 160 will be introduced before sealing. The edge of rim 140 is preferably substantially flat and circular so that a plane drawn across the mouth of the cylinder would intersect the rim 140 in substantially a circle, though the edge of rim 140 may optionally have an oblong shape. After sealing the container 100, the outer edges or rim 140 are incorporated into the seal no, i.e., fused to form the seal 110. The material forming the rim 140 has a thickness that is equal to or greater than the thickness of the cylindrical body 130.

[0067] The wall of the cylindrical body 130 may have a diameter in the range of 4 mm to 50 mm. In one aspect of the invention, the diameter of the cylindrical body 130 is in the range of 8 mm to 14 mm. The wall of the cylindrical body 130 may have a thickness in the range of 0.2 mm to 3 mm. In one aspect of the invention, the thickness of the wall of the cylindrical body 130 is in the range of 0.4 mm to 0.9 mm. The wall of the closed rounded tip 120 at the closed end of the container 100 may have a thickness similar to the thickness of the cylindrical body 130.

[0068] The length of the container 100 from the center of a diameter placed across the circular open edge 140 to the apex 125 may be in the range of 5 mm to 80 cm. In one aspect of the invention, the length of the container 100 is in the range of 10 mm to 30 mm.

[0069] To fill the container, the product is prepared for packaging, which may include curing, drying, hydrating, filtering based on such features as characteristics or size, decontaminating, irradiating, and the like. A pre-portioned amount of the product is introduced through the mouth of the container formed by the circular open edge of rim 140 and into the interior reservoir 105. The container 100 is then sealed.

[0070] To seal the container 100, two opposing edges of the circular open edge of the rim 140 are compressed or squeezed together. Heat is then applied to the two opposing rim edges that are juxtaposed (placed side by side adjacent to one another). Heat may be applied from the top of the juxtaposition, to the sides of the juxtaposition, or to both the top and the sides. Three types of elongated seals are provided, a T-shaped seal, a crimped seal, and a combination T and crimped seal. All types of seals are generally straight and are aligned with a diameter of the open, unsealed outer casing 150, particularly, the diameter between the juxtaposed edges. Due to the squeezing of the rim edges together and the deformation caused by the application of heat, the seal 110 will extend to a length greater than a diameter of the open outer casing 150 (as seen in the top views of FIGS. 3 and 10); this length is also generally equal to half of the circumference of the outer casing 150.

[0071] In one aspect of the invention, shown in FIGS. 1-7, the container 100 is configured with the T-shaped seal 110. The T-shaped seal 110 is formed when two opposing edges of the circular open edge of the rim 140 are forced together and heat is applied to the top of the juxtaposed rim edges. The application of heat causes the plastic material of the two edges to melt slightly and to fuse at seal 110 to close the top of the container 100, which creates lips 113. The seal 110 extends lengthwise having at its first end a first seal terminus 115, having at its opposing second end a second seal terminus 115, and having a center seamline 119 (shown in FIG. 10). The lips 113 are small projections formed on opposing sides of the seal 110 and extending between seal top 119 and the lip bottom niches 112 (FIG. 4). The lips 113 increase the thickness of the T-shaped seal 100 (FIGS. 3, 7) compared to the thickness of the top edge of the crimped seal 100 (FIGS. 10, 12). As seen in FIGS. 4 and 7, the lips 113 project outwardly beyond the outer upper surface of the wall 118 of the body 130 a distance that is approximately equal to, or slightly greater than, the thickness of the body walls. The thickness of the T-shaped seal 100 may vary based on factors such as the temperature of the applied heat and the length of application of the heat.

[0072] In another aspect of the invention, shown in FIGS. 8-14, the container 100 is configured with a crimped-type seal 110. The crimped seal 110 is formed when the two opposing edges of the circular open edge of the rim 140 are forced together and heat is applied to the sides of the juxtaposed rim edges. The application of heat causes the plastic material of the two edges to melt slightly (without creating significant lips 113) and to fuse, which creates crimped seal 110 having a center seamline 119 and ending in opposing seal termini 115. This closes the top of the container 100 to form a generally airtight seal. In the crimped seal aspect, the outer surface of the crimped seal is substantially in line with the outer surface 118 (FIG. 13) of the cylindrical body 130 directly below the seal and does not project outwardly beyond the portion of the outer surface of the cylindrical body 130 that is directly below the seal; the crimped-type seal no does not form lips 113 as does the T-shaped seal 100.

[0073] In further aspect of the invention (which has the same appearance as the T-shaped seal of FIGS. 1-7), the container 100 is configured with a combination T-shaped and crimped-type seal 110. The combination seal 110 is formed when the two opposing edges of the circular open edge of the rim 140 are forced together and heat is applied both to the rim sides and to the rim top of the juxtaposed rim edges. The heat application causes the fusing of the two edges and creates lips 113, as in the T-shaped seal 110. However, the application of heat from both the sides and the top may provide a stronger seal, as may be desirable for some types of plastic materials, for some sizes of containers, and for some weights of product.

[0074] To open the container, the consumer places a finger or thumb on the first seal terminus (at the first end of the seal) and an opposing finger or thumb on the second seal terminus (at the opposing end of the seal). The consumer then squeezes the first seal terminus toward the second seal terminus; this deforms the seam of the elongated seal, and this deformation 117 (potentially along with other factors such as the airtight characteristic of the container) causes the seal to snap open along the seam, which allows access to the product. This bursting of the seal 110 returns the shape of the container 100 to generally the shape the outer casing 150 had before the outer casing 150 was filled with the product 160 and before sealing.

[0075] After opening the sealed container 100, the user can pour the product 160 (whether liquid or solid) over the again-open outer edge of rim 140 and into a receiving area, vessel, repository, container, or holder (which is referred to generally as a receiving receptacle). In some aspects of the invention (particularly if the product 160 is a smokable product), the consumer may then use the closed rounded tip 120 to tamp the dispensed product down into the receiving receptacle. For example, if an adequate amount of the smokable product is poured into the receiving chamber of a pipe, the loosely packed product may not only tend to overflow the chamber, but it may also allow too much airflow when ignited. The closed rounded tip 120 may be used to more appropriately pack and/or compress the product to insure a smooth even burn. This eliminates the need for the consumer to obtain a separate tool to use for this tamping procedure. Additionally, using this method to tamp down the dispensed product, the consumer does not need to use his fingertip for this purpose, thereby preventing soiling of the finger and preventing the smokable product from sticking to the fingertip and being lost from the pipe chamber.

[0076] The container 100 is suitable for containing any of a variety of product materials. The product may be liquid, semi-liquid (for example, a gel or colloidal suspension), or dry matter (including solids). If the product is a dry material, it may be in the form of powder, particulates, flakes, crystals, granules, or other types of particulated matter that are sized to fit within the mouth of the container 100 created by the rim 140.

[0077] The product may be natural or synthetic; may be unprocessed, semi-processed, or processed; and may be in a concentrated form, natural or undiluted form, or diluted form. The product may comprise a single ingredient, a combination of ingredients, or a mixture of ingredients. The product may be edible, may be smokable, may be brewable, or may be able to be applied to human skin, to other living animals, to plants, or to inanimate objects. Examples of liquid products include, but are not limited to, lotions, creams, energy shots, flavorings, aromatics or perfumes, natural or processed oils, essential oils, tinctures, elixirs, liquid plant extracts, liquid vitamin mixtures, liquid mineral mixtures, liquid medicines, and fruit juice concentrate. Examples of dry products include, but are not limited to, brewable material, smokable material, and ingestible material. For example, coffee, tea, herbs and other botanical matter, spices, and the like are brewable materials suitable for packaging within the container 100. Ingestible materials include milk powder, dairy creamers, sweetening agents, natural and artificial flavors, cocoa-based ingredients, medicines, dried vegetables, herbs, spices, and the like.

[0078] The container 100 is particularly suitable for the packaging of botanical materials. The botanical matter utilized as the contained product 160 may be derived from any portion of the plant (stem, roots, leaves, buds, flower portions, bark, rhizomes, fruit, etc.) with different plant portions utilized depending on the particular plant variety that has been selected. The botanical matter may include, but it not limited to, leaves (such as tea or hemp leaves), flowers or buds (such as Cannabis buds), bark (such as the bark of cinnamon trees of the genus Cinnamomum), seeds (such as coffee or celery), or roots (such as the dried root of the celery plant (Apium graveolens). As an example, the botanical matter may be, but is not limited to, any of the following: tea leaves, coffee beans, yarrow flower (Achillea millefolium), Salvia species (including sages, Salvia apiana, and Salvia divinorum), Lamiaceae species (including peppermint and spearmint), Leonotis species (including wild dagga and klip dagga), plants of the Papaveraceae family (including celandine poppy and California poppy), blue lotus (Nymphaea caerulea), kratom, tobacco, herbal non-tobacco, mugwort, coltsfoot leaf, Heimia salicifolia, St. John's wort, Melissa officinalis, skullcap (Scutellaria laterifolia), Yerba lenna yesca, Capillaris Herba, Calea zacatechichi, Leonurus sibericus, kava, Avena sativa, kanna, Lactuca virosa, clove, myrrh, willow, Cornus (dogwood including red osier), pipsissewa (Chimaphila umbellata), pyrola, kinnikinnik, arctostaphylos uva-ursi, camomile, manzanita, Arctostaphylos species, madrone, Arbutus menziesii, Rubus species (raspberry, blackberry, etc.), scotch broom (Cytisus scoparius), Cannabis species (including sativa, indica, and ruderalis), calamus, Verbascum species (mullein), Cinnamomum species, Elettatia cardamomum, plants of the Aquilaria genus, Crocus sativus, Santalum album, Withania somnifera, Mucuna pruriens, Mimosa hostilis, Celastrus paniculatus, Emblica officinalis, Terminalia chebula, Terminalia bellerica, Solanum xanthocarpum, Glycyrrhiza glabra (licorice), Ocimum sanctum, Zingiberaceae family (including Curcuma longa (turmeric) and Zingiber officinale (ginger), a'hai, celery plant (Apium graveolens), Commiphora mukul, Boswellia serrata, Vitex negundo, Bacopa monnieri, Cyperus rotundus, Myristica fragrans, Valeriana wallichii, Nardostachys jatamansi, Acacia confusa, Passifloraceae species, Echinacea purpurea, milk thistle (Silybum marianum), Angelica species (including Angelica archangelica), catnip plants (Nepeta cataria), lavender (Lavandula angustifolia), Taraxacum species (including dandelion), linden tree flowers, lemon verbena (Aloysia citrodora), and gotu kola (Centella asiatica).

[0079] The outer casing 150 is preferably formed unitarily of a plastic resin, which is most preferably low-density polypropylene (LDPE). Preferably blow molding is used to create the outer casing 150. However, other methods of forming plastic containers (such as injection molding, vacuum forming, or thermoforming) are within the scope of the invention. An interior coating or an interior lining may be included within the outer casing 150 to provide benefits such as a reduction in oxygen permeability, to decrease flavor scavenging in which the plastic absorbs flavors from the product, and the like. An interior coating may be formed of polytetrafluoroethylene (such as the Teflon brand of PTFE), nylon, aluminum, or the like.

[0080] The type and/or amount of product enclosed within the snap container 100 may be disclosed to the consumer through one or multiple means of indication. In one aspect of the invention, the plastic material is transparent or translucent; this enables the consumer to view the product packaged within the container, which may give an indication of the type of amount of product contained. In another aspect of the invention, the packager adheres a label onto the side of the container 100 to indicate the content type and amount enclosed within the snap container 100. In a further and preferred aspect of the invention the outer casing 150 is manufactured in multiple colors of plastic with each color representing a product type and/or an amount.

[0081] The usage of more than one color may provide advantages in that it enables the packager to package a first product in a first color of casing 150, to package a second product in a second color of casing 150, etc. or to package a first amount or dosage of a product in a first color of casing 150, a second amount or dosage of a product in a second color of casing 150, etc.

[0082] This color-to-type or color-to-amount coding allows the packager to indicate the product type or the product amount to the consumer, even though the consumer cannot view the product inside through transparent or translucent packaging, and even if the packager does not desire to adhere a label to a side of the container 100. The container 100 may be considered more elegant and/or more aesthetically pleasing without an adhered label.

[0083] The consumer can be notified of the coding (the association of a particular color or particular dosage with a particular enclosed product) in any of a variety of ways, even without labeling on the container 100 itself. For example, an outer wrapper, outer carton, outer box, advertising materials, signage, or the like may allow the consumer to associate a first type or dosage of product contained to a first color.

[0084] This coding indication to the consumer of the type or amount of enclosed product within the container 100 aids the consumer in both determining dosage and in creating personalized blends and mixtures. If a blue container 100 contains a defined amount of Virginia tobacco and an orange container 100 contains a defined amount of Turkish tobacco, the consumer may carry a blue container 100 and an orange container 100 with him, knowing that he can blend his own preferred custom-made pipe tobacco with the two containers he has brought with him. This occurs without the need for the packager to provide labeling on the individual container 100. Also, unless a nearby person also knows the coding system, the ingredients of the custom-made pipe tobacco are not disclosed to nearby companions.

[0085] Due to the novelty of the inventive container 100, no conventional machine was currently available for the positioning, securing, and heating of the outer casing 150 to create the container 100. Thus, FIG. 22 discloses a positioning, holding, and heating machine 200 for the creation of the containers 100 from the pre-formed outer casings 150.

[0086] The holding and sealing machine 200 comprises at least one row of multiple wells 210 and preferably multiple rows of wells 210. Each of the wells 210 have an interior diameter slightly larger than the outside diameter of the outer casing 150 to be sealed to allow an outer casing 150 to be introduced into a well 210. Each well 210 has a peripheral wall 211, the outer (upper) edges of which define an opening 212 that will accommodate the outer casing 150. The floor of the well 210 may be flat or may be concave in correspondence with the convex tip 120 of the casing 150.

[0087] The holding and sealing machine 200 comprises sliding rails 235, 245 that slide in opposite directions to compress the sides of the casing 150 to juxtapose opposing rim edges in preparation for formation of the seal. In the exemplary aspect shown in FIG. 22, sliding rails 245 slide to the left; sliding rails 235 slide to the right.

[0088] The left sliding rails 245 are fixedly attached to sliding shaft 240 that slides left. When left sliding shaft 240 is moved leftward (either manually or mechanically) the left sliding rails 245 slide to the left.

[0089] The right sliding rails 235 are attached to a right sliding shaft 230. When right sliding shaft 230 is pulled (either manually or mechanically) the right sliding rails 235 slide to the right.

[0090] The end one of the right sliding rails 235 may be fixedly attached to the end of the right shaft 230, but any middle ones of the right sliding rails 235 are fixedly attached to a middle portion of the shaft 230. To allow the right shaft 230 to slide, the left sliding rails 245 are configured with a channel 241 that is sized and shaped to accommodate the right shaft 230. The right shaft 230 slides within the channel 241 to move the right rails 235.

[0091] Solid structures 225 may be interspersed with open spaces along the edge of the machine 200 with the shafts 230, 240. The open spaces allow access to the shafts 230, 240, such as for manual manipulation of the shafts. The sliding of the shafts 230, 240 and of the rails 235, 245 may be actuated by an electric motor to mechanize the operation, if desired.

[0092] To use the holding and sealing machine 200, multiple outer casings 150 are obtained in one or more colors or transparencies. Each outer casing 150 to be sealed is oriented with the closed rounded tip 120 disposed within a well 210. The right sliding shaft 245 is slid right, and the left sliding shaft 235 is slid left. These movements pull the right rail 245 toward the left rail 235 and compress the rim edges of opposing sides of the cylindrical body 130 to position the opposing rim edges adjacent each other. Heat is then applied to the sides of the rim, to the top of the rim, or to both rim sides and rim top of the juxtaposed rim edges of the cylindrical body 130.

[0093] In an example of applying heat to the rim top to create a T-shaped seal, the heat is applied by a flat heated platen that pressed down onto the top juxtaposed rim edges of the cylindrical body 130 with between 5 pounds and 7 pounds of force for 2 to 4 seconds. The heated platen is preferably covered with a non-stick surface material and is heated to between 350 degrees F. and 370 degrees F. The application of the heat from the heated platen melts and flattens the top 1 mm to 2 mm of the exposed plastic into the T-shaped seal. Other similar applications of heat are within the scope of the invention. For example, heating the heated platen to a slightly higher heat may allow the heat application time to be reduced or may allow the downward force to be decreased, and heating the platen to a slightly lower heat may require a longer heat application time or a slightly greater downward force.

[0094] Since many modifications, variations, and changes in detail can be made to the described preferred embodiments of the invention, it is intended that all matters in the foregoing description and shown in the accompanying drawings be interpreted as illustrative and not in a limiting sense. Thus, the scope of the invention should be determined by the appended claims and their legal equivalents.
