Manufacturing

The container body may comprise any materials as can be appreciated by one having skill in the art, including but not limited to metal, glass, plastic, or a combination thereof. In some embodiments, the container body comprises an aluminum can with the proximal opening and the distal opening having pop tops with pull tabs being optionally hermetically sealed. The container body may comprise rotating lids or screw tops with threaded elements. The covers for the proximal opening and distal opening may be same or different.

The sensor of the remote monitoring subsystem may be configured to measure various parameters including pressure, direct CO₂ levels, temperature, pH balance, low ppm sensing to high ppm sensing, or a combination thereof. The subsystem comprises a power source such as a battery which is sealed from either compartment of the container. The remote monitoring subsystem may comprise wireless capabilities including Bluetooth or NFC. In some embodiments, the remote monitoring subsystem may further comprise GPS capabilities for tracking the container.

The first compartment and the second compartment may comprise a same volume or different volumes. For example, in a 12-ounce can, the first compartment and second compartment may each comprise 6 ounces. Or, the first compartment may comprise 9 ounces and the second compartment may comprise 3 ounces.

Methods of manufacture can be various techniques including blow molding, injection molding, two-piece can manufacture processes, and glassblowing processes.

In one aspect, a method of manufacturing a dual compartment metallic can is disclosed. The aluminum coils arrive at the can plant and are loaded one at a time onto an “uncoiler”—a machine that unrolls the strip of aluminum at the beginning of the can making line and feeds it to the line, where it is first lubricated. Lubrication helps the aluminum flow smoothly during the can shaping processes that follow. Sheets are inspected for surface defects and imperfections, ensuring high-quality starting material. Two aluminum sheets are each sized for a single can compartment. Both sheets are treated to achieve the desired thickness, typically around 0.10-0.15 mm. Both sheets are then preheated to approximately 900-950° C. to soften the aluminum for shaping. The drawing presses are employed to form each sheet into a cup shape. Each cup-shaped sheet is ironed to achieve the final desired thickness. An optional annealing process at 350-400° C. may be employed to relieve stresses and restore mechanical properties. Next, the necking process is performed for each can compartment to create openings for pop-top lids, adhering to strict dimensional tolerances. Lubrication during necking with food-grade lubricants is used to reduce friction while maintaining product safety. A large machine called a cupping press is used for the can shaping process. The press cuts circular discs from the aluminum sheet and forms them into shallow cups. The cups drop from the press onto the cup conveyor. Ensure neck dimensions match precisely with pop-top lid specifications. Typical dimensions: neck diameter of 53-57 mm, height around 7-9 mm, with allowances for variations within microns. From the cupping press, the cups are drawn up into higher cups through a series of iron rings. Align the necked ends of both compartments accurately. A specially designed chuck made from stainless steel is utilized for joining the two cylinders. A sealing mechanism is incorporated into the chuck design, utilizing food-grade O-rings or gaskets made of materials compliant with food safety regulations. A radial pressure is applied evenly around the circumference of the necked ends using a two-part crimping mechanism for ultimate sealing precision. The first part of the crimping mechanism applies precisely controlled initial pressure to secure the chuck and create a preliminary seal. This pre-crimping step ensures uniform contact between the chuck and the can compartments. The second part of the crimping mechanism applies calibrated radial pressure to complete the seal with microstrain accuracy. As pressure is applied, the aluminum material of the necked ends undergoes controlled deformation, forming a hermetic seal at the interface of the two compartments. Next, one compartment is filled with the desired beverage, maintaining precise fill levels through automated volumetric controls. The first pop-top lid is securely attached to the filled compartment's necked end, ensuring a hermetic seal with tamper-evident features. The second compartment is filled with a different or the same beverage, adhering to the same strict fill level standards. The second pop-top lid is securely attached the second compartment's necked end, ensuring a secure seal with integrated tamper-proof technology.

In another aspect, a method of manufacturing a dual compartment plastic bottle is disclosed. Plastic material choice can vary and can include polyethylene terephthalate (PET), high-density polyethylene (HDPE), or polypropylene (PP). In some embodiments, a combination of these plastics may be employed to achieve the desired properties such as strength, clarity, and barrier resistance. The manufacturing process begins with the production of a preform—a small, thick-walled tube of plastic that is heated and then blown into the final container shape. The preform design will vary based on the size of the final container, e.g., 2-liter or 16-ounce bottles. Preforms are produced using injection molding. Plastic pellets are melted and injected into a preform mold to create the solid, tube-like structure. For dual compartment containers, the preform design will need to accommodate two separate chambers. This involves creating a preform with a bifurcated internal structure. The preforms are heated in an oven to a temperature that makes them soft and pliable, typically around 240-260° C. (464-500° F.). Once heated, the preforms are transferred to a blow molding machine. For dual compartment containers, a two-step blowing process is performed wherein a first blowing step expands the first compartment, and a second blowing step expands the second compartment. After the container is fully expanded and formed, it is cooled to solidify the plastic. This step ensures that the container retains its shape and structural integrity.

Each of the components of the dual compartment container described herein may be manufactured and/or assembled in accordance with the conventional knowledge and level of a person having skill in the art.

While various details, features, combinations are described in the illustrated embodiments, one having skill in the art will appreciate a myriad of possible alternative combinations and arrangements of the features disclosed herein. As such, the descriptions are intended to be enabling only, and non-limiting. Instead, the spirit and scope of the invention is set forth in the appended claims.

Illustrated Embodiments

FIG. 1-4 shows a dual compartment container (100) in accordance with various embodiments. The dual compartment container comprises a container body (101) extending from a proximal end (103) to a distal end (104). The container body comprises a hollow interior (102) surrounded by inner walls (106). Opposite the inner walls is an exterior surface (105) which a user is capable of contacting. Disposed within the hollow interior is a separator (110) that divides the hollow interior into two separate and independent compartments, namely a first compartment (120) and a second compartment (130). The first compartment extends from the separator to the proximal end, and the second compartment extends from the separator to the distal end. The proximal end comprises a proximal opening (112) for accessing a first substance (122) within the first compartment. The distal end comprises a distal opening (113) for accessing a second substance (132) within the second compartment.

The separator (110) forms a sealed coupling to the inner walls (106) of the container body (101) by a scaling mechanism. Sealing mechanisms can include welding, brazing, press-fit with gasket, crimping, ultrasonic welding, snap fit with O-ring, adhesive bonding, thermal scaling, compression fit with gasket, mechanical fastening with epoxy, glass bonding with frit seal, or the like. The sealed coupling allows for the separator to be an impermeable membrane to avoid mixing of the substances in the first compartment and the second compartment that can include solids and/or fluids. An airtight seal of the separator segregates the two substances which can be equivalent or complementary to each other. Having equivalent substances in the first and second compartments preserves freshness of one of the substances being opened at a later time. For complementary substances, the dual compartment container allows for a convenient packaging and storage vessel where the complimentary products can be used together.

The first compartment (120) comprises a first volume (121) and the second compartment (130) comprises a second volume (131). In some embodiments, the first volume is equal to the second volume. This can be useful in applications such as pressurization equalization or where the two substances are used in generally equal proportions. In other embodiments, the first volume is greater than the second volume. To maximize both the first and second volumes, the separator may comprise a planar formation, such as a disc, with a generally flat substrate. One having skill in the art will appreciate that reinforcement elements and curvature of the separator for structural integrity is still interpreted as the separator being generally a flat substrate. The container body comprises an interior periphery (107) formed by the inner walls (106). The interior periphery may comprise a circular or round shape as is common in conventional containers such as aluminum cans or metal/plastic bottles. The separator may comprise a separator periphery (111) that comprises the same periphery as the interior periphery in order for the separator to efficiently isolate the first compartment from the second compartment.

Various types of containers may utilize the dual compartment configuration as disclosed herein. Examples may include metallic cans, plastic bottles, glass bottles, or any other container as can be appreciated by one having skill in the art. Substances contained within each compartment may be edible or inedible. The dual compartment container can be used in various industries including food, medical, consumer, industrial, and the like. Generally, the proximal opening (112) and the distal opening (113) each comprise a cover to store contents therein while not in use. Covers may include pop tops (140) with hermetic seal and elastomeric scaling ring, removable snap covers (141) configured to detachably couple and decouple for repeated use, and threaded covers (142) typically seen in plastic and glass bottles.

FIG. 5-7 show a dual compartment container (100) with a mixing mechanism (200) according to a fourth illustrated embodiment. The dual compartment container comprises a container body (101) extending from a proximal end (103) to a distal end (104). The proximal end forms a container top side (207) and the distal end forms a container bottom side (208) opposite the container top side. The dual compartment container further comprises an external surface (105) and inner walls (106) opposite the external surface wherein the inner walls surround a hollow interior (102). A separator (110) divides the hollow interior into a first compartment (120) and a second compartment (130) such that contents in the first compartment are isolated from contents in the second compartment. The separator is coupled to the inner walls and the bottom container side by a plurality of perforated seals, namely a first perforated side seal (202), a second perforated side seal (203), and a perforated bottom seal (204). The first perforated side seal couples a first half (210) of the separator to the inner wall at one side of the container body. The second perforated side seal couples a second half (211) of the separator to the inner wall opposite the first perforated side seal. The perforated bottom seal couples the separator to the container bottom side. Each of the perforated seals isolates the first compartment from the second compartment and while intact prevents mixing of contents stored therein.

The mixing mechanism (200) allows the separator (110) to rotate within the container body (101) to mix contents stored within the first compartment (120) with contents stored with the second compartment (130). The mixing mechanism comprises a center post rod (201) bisecting the separator into the first half (210) and the second half (211). The center post rod is rotatably coupled to the container bottom side (208). Coupled to the center post rod and extending above the hollow interior is a twist tab (206) to provide ergonomic turning of the separator. Upon rotation of the twist tab and subsequently the center post rod, the separator is configured to rotate and break from the plurality of perforated seals, thereby allowing the contents inside the first and second compartments to converge and mix. To encourage proper mixing, the separator comprises a contoured surface (205) at a top edge (212). The first half and the second half each comprise the contoured surface such that the first half and the second half are characterized as being in a mirror configuration with each other. Each contoured surface comprises a curvature that decreases toward the center post rod. Both the first compartment and the second compartment may comprise a lid to prevent spilling. After mixing is complete, a compartment access point (209) can be utilized to open the first compartment, the second compartment, or both to access the contents therein. In some embodiments, the dual compartment container may further comprise additional compartments (e.g. a third compartment, a fourth compartment, etc.) without deviating from the spirit of the embodiment. Generally, the separator is configured to rotate both clockwise and counterclockwise. In some embodiments, the mixing mechanism may further comprise a crossmember bar extending fully across the diameter of the hollow interior such that terminal ends of the crossmember bar contacts opposite sides of the interior periphery of the container body. The crossmember bar is fixedly coupled to the inner walls of the container body with the separator rotating independently below the crossmember bar. The crossmember bar improves the ability to rotate with resistance. The crossmember bar adds improved strength for hinge rotation and the separator support.

FIG. 8-9 show a dual compartment container (100) according to a fifth illustrated embodiment. The dual compartment container comprises a first compartment (120) and a second compartment (130) wherein the first compartment is associated with a first container (300) and the second compartment is associated with a second container (301). The first container is separate and distinct from the second container. The first container and the second container may comprise similar or identical features for attachments to additional containers. One having skill in the art will appreciate that features disclosed for the first container may also apply to the second container. The first container extends from a proximal end (103) to a distal end (104) and has a container body (101) with the first compartment surrounded by an exterior surface (105). Disposed at the proximal end is a proximal opening (112) for accessing contents within the first compartment. The proximal opening comprises opening threads (308) for engagement with a lid. The first container further comprises a threaded recess (309) disposed at the distal end.

A corresponding lid (302) is shown configured to engage with the proximal opening (112) at both the first container (300) and the second container (301). The lid comprises a lid outer periphery (303) and a lid inner periphery (304) opposite the lid outer periphery. The lid inner periphery comprises internal threads (307) configured to engage with the opening threads. The lid outer periphery comprises both gripping grooves (305) and external threads (306). The gripping grooves are provided to increase gripping capabilities for proper tightening and loosening. The external threads are configured to engage with the threaded recess of the second container. This allows for two containers to be stacked and coupled together for transportation and storage.

The gripping grooves (305) comprise threads having a thread direction orthogonal to the external threads (306). The gripping grooves are shown disposed near a top of the lid on the lid outer periphery (303) such that the gripping grooves are disposed above the external threads when the lid is coupled to the first container (300). This increases case of use when tightening or loosening. The external threads and the internal threads (307) are disposed on opposite sides of the lid periphery such that the external threads are directly external to the internal threads.

In some embodiments, the lid may further comprise a remote monitoring system (400) including a sensor (401). The remote monitoring system further comprises a battery (402) and wireless connectivity module (403) such as NFC or Bluetooth. The sensor is configured to measure one or more parameters including pressure, temperature, CO₂ levels, and the like. The sensor is disposed on an underside portion of the lid with a barrier seal covering the sensor from contents contained within the associated container.

FIG. 10 shows a dual compartment container (100) according to a sixth illustrated embodiment. The dual compartment container comprises a container body (101) extending from a proximal end (103) to a distal end (104) with a separator (110) dividing a hollow interior (102) of the container body into a first compartment (120) and a second compartment (130). The separator extends radially toward inner walls (106) of the container body. The separator comprises ribs (500) and impressions for increased strength and rigidity between the first and second compartments. The ribs extend laterally along the separator towards opposite sides of the inner walls. The separator further comprises a cavity (501) for receiving a remote monitoring subsystem (400) including a sensor (401). The sensor is configured to slide within the cavity and is then hermetically sealed during the crimping process.

FIG. 11-12 show a diagram and flow chart for manufacturing metallic cans. Conventionally, a cylinder of the can is initially molded and stretched over repetitive incremental steps to create the bottom. The pre-assembled pop top lid edge is then folded in with the top cylindrical can edge. An adhesive combined with the double fold crimp creates the hermetic seal. In order to create the separator, the cylinder length can decrease as two separate cylinders are desired. The components comprise two cylinders, two preassembled pop top lids, and a seaming chuck. The first cylinder is conformed to the point where it has the open top and solid bottom, (standard process point). Its bottom would then be folded into the other cylinder in the same fold adhesive process used for the standard top connection. At that point, both cylinders would be separated internally but connected. With the fold marrying in the middle, it would keep the can strong enough to go through the filling of the container with contents, and for the crimp adhesive fold for the pop top at the top and bottom. To accomplish this, the edge of the first cylinder's closed bottom outer edge would be specially modified to accept the other cylinder but again the same fold process for the top would be the same method of connection. And as the can bottom has a dome shape the fold would go up inside that edge giving the can a finished side wall with a seam/crease connection circle around the cylinder. Inner linings may be applied to the bottom of the first cylinder outer bottom.

FIG. 13 shows a diagram for a method of manufacturing a metallic dual compartment can. Step 1: A slightly longer tapered cylinder is molded with a closed end, where the perimeter of the closed end features excess material around the cylinder wall at the junction with the end of the closed section. This preformed design provides sufficient excess material to facilitate the crimping, folding, and sealing processes during manufacturing. The cylinder is designed, engineered, and measured to ensure equal contents once the crimping and conjoining processes are completed. This step also includes the installation of a concealed micro sensor, wrapped in a protective coating, within the pre-molded hollow cavity. Step 2: The pre-molded closed side of compartment one is prepared for attachment to the cylinder. The open-ended cylinder of compartment two is engineered, designed, and measured such that, following the crimping and sealing processes, both compartments are equal in size. The initial folding process aligns the ends of the two compartments in an “S” shape, facilitating their interlocking. As the crimp folds in, this step also begins the hermetic sealing of both compartments and the pre-molded section for the micro sensor, which is encased within the outer wall perimeter and the compartment divider, ensuring it remains unobtrusive during the crimping process. (See FIG. 11). Step 3: The second phase of the crimp-fold process involves the melding, connecting, and fusing of the two separate compartments. Upon completion of this step, both compartments are hermetically sealed, and the micro sensor is positioned to sense conditions in either compartment, or both simultaneously. At this stage, the dual compartment container achieves sufficient rigidity and stability to proceed to the next manufacturing phase. Step 4: After the connection process, the first compartment of the dual compartment container is ready for filling and scaling. Following a precisely measured filling, the first pop top is installed through the crimping and sealing process (see Steps 2 and 3, and FIG. 11). Once the contents of the first compartment are filled and sealed, the sensor can immediately begin sensing that compartment. Step 5: The dual compartment container is rotated vertically and the second compartment undergoes the connection process, preparing it for filling. After a precisely measured filling and sealing, the second pop top is installed through the crimping process (see Steps 2 and 3, and FIG. 11). Once the contents of the second compartment are filled and sealed, the sensor can begin sensing that compartment independently, or it may sense both compartments simultaneously. Step 6: Both compartments have been hermetically sealed on all sides, with pop tops installed at both ends. The sensors are operational. The container is now ready for quality control, during which each container undergoes rigorous inspections to ensure that seals are intact, the filling process has not compromised the container's integrity, and that the sensors are functioning correctly.

FIG. 14A-C show diagrams for a two-part method for manufacturing a dual compartment container. The two-part blow molding process for creating a dual compartment container involves several steps, utilizing specialized equipment and molds to produce a fused product with two identical compartments. The process begins with the extruder, where plastic resin is heated and melted. This molten plastic is then fed into a die head, which forms a parison—a hollow tube of plastic. The first mold comprises a cavity designed to create one compartment with a finished bottom and designed to accept a screw cap or any desired cap or lid. The parison is positioned inside the first mold. Air is introduced through an air hose to expand the parison against the walls of the mold cavity, forming the first compartment. Cooling lines in the mold help solidify the plastic as it takes shape. After the first compartment is formed and cooled, it is transferred to the second mold, which is designed to attach to the first compartment's bottom end, the end opposite the female or male screw cap, or any cap or lid opening. The second mold also has a cavity to create a second compartment of identical volume. The second mold designed to hold both compartments aligns the two compartments and is sealed. Blow pins from the second mold help ensure a proper fit and connect the two compartments together with the barrier from the first blow abutted to the other compartment's bottom end. The space between the compartments allows for the fusing of both compartments in the second blow. Air is again introduced via the air hose, causing the parison to expand and fill the second mold cavity. This forms the second compartment and fuses the two compartments, creating a seamless connection between the two compartments with a strong barrier in between. As with the first blow, cooling lines facilitate the solidification of the plastic, ensuring the integrity of the structure. Once both compartments are molded and cooled, the dual compartment container is fully formed. At this stage, it is ready for filling. The first compartment can now be filled with the desired product, followed by the installation of a lid to seal it. Next, the second compartment can now be rotated and filled with the desired product, followed by the installation of a lid to seal it. The fused dual compartment container is rotated for inspection to ensure quality standards are met. Finally, a heat shrink label wrap is applied around the container to enhance binding and add strength to the finished product. Components of the diagram are as follows: Air Hose: Supplies air for blowing the parison into the molds; Die Head: Extrudes the molten plastic to form the parison; Extruded Parison: The hollow tube of plastic that is blown into the mold; Cooling Lines: Circulate coolant to solidify the plastic during molding; Mold Cavity: The interior shape of the mold that determines the final form of each compartment; Blow Pins: Mechanisms that help secure and align the two mold sections during the fusing process; Finished Molded Dual Compartment Container: The final product consisting of two fused compartments ready for filling and labeling. The two-part blow method efficiently produces dual compartment containers that are strong and functional, with precise volume control and seamless integration between compartments. This process ensures high-quality manufacturing suitable for a wide range of products.
