Embodiments described herein generally relate to a multi-barrier bottle formed from a bottle preform and, more specifically, to a bottle preform with at least one preform extension piece.
Bottle preforms may be produced as an inner barrier of a bottle that comprises a polymer or other similar material that is blow molded, extruded, or otherwise expanded to a predetermined final shape, thereby resulting in bottles that are used for many different purposes, such as for containing beverages, culinary ingredients, cleaning products, beauty products, automotive products, and/or other fluids. While current methods of bottle production may utilize interior and exterior barriers, many of these current processes are inefficient in terms of material usage and result in misalignment between the barriers, causes the bottle to be structurally insecure. Accordingly, there exists a need in the industry for more efficient material usage and ensuring appropriate alignment between barriers.
In one embodiment, a tabbed preform includes an elongate body extending into a cavity of a first barrier, where the cavity is defined by at least one piece having a recess therein. The tabbed preform further includes at least one preform extension piece extending from the elongate body at a predetermined distance from a top surface of the elongate body. The at least one preform extension piece is sized and shaped to correspond to a size and a shape of the recess.
In another embodiment, a multi-barrier bottle includes a first barrier having a first piece and a second piece that define a cavity within the first barrier and a second barrier formed from a tabbed preform. The first piece includes a first recess and the second piece comprises a second recess. The tabbed preform includes an elongate body extending into the cavity within the first barrier and first and second preform extension pieces extending from the elongate body at a predetermined distance from a top surface of the elongate body. The first and second preform extension pieces are received in the first recess and the second recess of the first barrier.
In yet another embodiment, a multi-barrier bottle includes a first barrier having a first piece and a second piece that define a cavity within the first barrier, and a second barrier formed from a blow molded tabbed preform. The first piece includes a first recess and the second piece includes a second recess. The blow molded tabbed preform includes an elongate body extending into the cavity within the first barrier, first and second preform extension pieces extending from the elongate body at a predetermined distance from a top surface of the elongate body, where the first and second preform extension pieces are received in the first recess and the second recess of the first barrier, and a plurality of beads extending from the elongate body around a circumference of the elongate body, where the plurality of beads are located between the first and second preform extension pieces and the top surface of the elongate body and maintain a positioning of the tabbed preform with respect to the first barrier such that the first barrier is in contact with the at least one bead.
These and additional features provided by the embodiments described herein will be more fully understood in view of the following detailed description, in conjunction with the drawings.
The embodiments set forth in the drawings are illustrative and exemplary in nature and not intended to limit the disclosure. The following detailed description of the illustrative embodiments can be understood when read in conjunction with the following drawings, where like structure is indicated with like reference numerals and in which:
Bottle preforms are generally used as predecessor materials for bottles, particularly plastic bottles. That is, a bottle preform may be configured as an amorphous structure that is produced from a material, such as a resin or the like, by melting the resin in an extruder and injection molding the molten resin into a preform shape. Such a preform usually includes an outside surface area that is generally smaller than the outside surface of the bottle that results therefrom. To make a bottle from the preform, the preform may be heated to an orientation temperature such as, for example, about 30° C. above the glass transition temperature. The heated preform is then placed into a bottle mold and formed into a bottle by stretching the preform and inflating it with high pressure air.
The resin materials that may be used for preform production include polyester resins, such as polyethylene terephthalate (PET) and its copolyesters. However, other polymer resins that may be used for preforms are generally understood. Such resins may be considered harmful to the environment, as they are oftentimes not biodegradable. As such, it may be desirable to minimize use of the resin material to reduce the amount of material that may potentially end up in a landfill while at the same time avoiding degradation of the quality and purpose of the resultant bottle.
Embodiments disclosed herein include a bottle preform that decreases the amount of material used to form the bottle preform. In addition, the bottle preform provides an orientation capability during production to ensure the preform is appropriately aligned with an outer barrier layer. That is, the quantity of polymer per bottle can be reduced by using the preform described herein to impart orientation in the resultant bottle sidewall, thereby improving resultant bottle strength.
While the preform described herein relates generally to a preform used in forming a bottle, the present disclosure is not limited to such. For example, the preform may be used to form any of an article, a container, and/or the like. As such, it should be understood that a “bottle preform” refers to a preform in the general sense and not solely a preform that is used to form a bottle.
Similarly, embodiments described herein may be configured as a multi-barrier container. Embodiments that utilize a multi-barrier configuration may include a plurality of layers of barrier material, including an outer barrier layer and an inner barrier layer formed from the preform. A barrier material may include any material that is used to form a gas barrier from the gases that are used when forming a bottle from the preform. In addition, the barrier material may also include any material that is used to form a gas barrier for the eventual contents of the resulting bottle (e.g., a bottle filled with carbonated drinks contains carbon dioxide). Other embodiments are also contemplated.
Referring now to the drawings,
In some embodiments, the exterior barrier 102 may be created from a single piece of material. That is, the exterior barrier 102 may be particularly formed as a one piece component. For example, the exterior barrier 102 may be formed by molding (e.g., injection molding, compression molding, or the like), extruding (e.g., extrusion molding), sculpting, blowing, or the like into a single piece unit. As an example, the single piece of the exterior barrier may be wrapped and seamed to create an enclosure defined by the exterior barrier 102. In other embodiments, the exterior barrier 102 may be created by joining a plurality of pieces together at a plurality of seams. For example, the exterior barrier 102 may be formed by fusing a first piece to a second piece, as will be described herein.
In some embodiments, the exterior barrier 102 may be sized to define a predetermined interior volume for containing the fluid (e.g., a volume of the cavity 105). For example, the exterior barrier 102 may define an interior volume of about 1 milliliter (ml), about 10 ml, about 50 ml, about 100 ml, about 250 ml about 500 ml, about 750 ml, about 1 liter, about 1.5 liter, about 2 liter, about 2.5 liter, about 5 liter, about 10 liter, etc. or any value or range between any two of these values (including endpoints). However, it should be understood that the volumes listed herein are merely illustrative and that the present disclosure is not limited to such.
The exterior barrier 102 may contain indicia 108 thereon or incorporated therewith. For example, the indicia 108 may be located on one or more of the walls 103 of the exterior barrier 102. The indicia 108 may be printed directly on the exterior barrier 102, affixed to the exterior barrier 102, formed in a surface of the exterior barrier 102 (e.g., an embossed indicia), and/or the like.
In various embodiments, the exterior barrier 102 may be constructed of an ecologically friendly material. While not exclusively limited to such, an ecologically friendly material may be a biodegradable material, compostable material, recyclable material, etc. Illustrative ecologically friendly materials may include, but are not limited to, agricultural processing materials, such as forms of sugarcane (bagasse), bamboo, wheat straw, banana leaves, hay, grasses, cornstalks, recycled pulp, fiber materials, and/or the like. Other illustrative ecologically friendly materials may include, but are not limited to, post-consumer waste, such as newsprint, packaging, other forms of paper products, and/or the like that may or may not have been recycled and/or repurposed for a particular application as described herein. Yet other illustrative ecologically friendly materials may include, but are not limited to, composite materials, such as materials obtained from landfill and/or municipal reclaim centers, including architectural wood, building materials, manufacturing byproducts, and/or the like. It should be understood that one or more other ecologically friendly materials not specifically described herein may also be used without departing from the scope of the present disclosure.
The interior barrier 104 may be constructed of a polymer material or the like, particularly materials that are capable of being blow molded and/or extruded. In some embodiments, the interior barrier 104 may be a preform, and thus may be constructed of materials that are used for preforms, particularly bottle preforms. As described above, illustrative materials may include, but are not limited to, PET and its copolyesters. Other illustrative materials may include polyether block amides (e.g., PEBAX), nylons, polyurethanes, polyethylenes (e.g., high density polyethylenes (HDPE), ultra-high-molecular-weight polyethylenes (UHWPE), low density polyethylenes (LDPE), or any combination thereof), biaxially-oriented polyethylene terephthalates (e.g., mylar), and other polymers and thermoplastic polymers, fabrics, silicones such as silicone rubber, latex, glass, or other materials now known or later developed.
The interior barrier 104 may be particularly sized and/or shaped such that it can fit within a volume defined by an interior surface of the exterior barrier 102, such as through an opening 111 in the cavity 105. In embodiments where the interior barrier 104 is a preform, the size and shape may generally correspond to typical preform shapes and/or sizes prior to forming the bottle from the preform. Other sizes and/or shapes of the interior barrier 104 should generally be understood.
In various embodiments, the multi-barrier bottle 100 may also include a removable cap 106. The removable cap 106 may be attachable to at least a portion of the multi-barrier bottle 100 via one or more attachment members 109 located on at least a portion of the multi-barrier bottle 100 and/or the removable cap 106. For example, the removable cap 106 may contain one or more threads (not shown) that correspond to one or more threads that define the attachment members 109. As such, the removable cap 106 may be screwed onto the top portion 107 of the interior barrier 104 to secure the components together, as depicted in
The removable cap 106 is not limited by this disclosure in shape, size, composition, or securing mechanism. In some embodiments, the removable cap 106 may correspond in shape and size to the top portion 107 of the interior barrier 104 such that the removable cap 106 can be securely placed on the interior barrier 104. In some embodiments, the removable cap 106 may have various dimensional aspects that are generally recognized as being a standard shape and/or size. Similarly, some embodiments may be configured such that the removable cap 106 may be flexible and removed by deforming the flexible cap and/or performing other action to remove the removable cap 106 from the attachment members 109. Depending on the embodiment, the removable cap 106 may or may not be configured to reattach to the attachment members 109 once removed.
As illustrated in more detail in
As illustrated in
The preform extension pieces 202 may be coupled to the tabbed preform 200 at various locations around the circumference of the elongate body 214 of the tabbed preform 200. For example, the preform extension pieces 202 may extend from an exterior wall 201 of the tabbed preform 200. In addition, the preform extension pieces 202 may be located at or near a top surface 212 of the tabbed preform 200. In some embodiments, the various preform extension pieces 202 may be substantially evenly spaced from one another around the circumference of the elongate body 214 of the tabbed preform 200. For example, as particularly shown in
The preform extension pieces 202 may be a particular shape and/or size to correspond to the shape and/or size of the recesses 210 in the exterior barrier 102. Thus, when the exterior barrier 102 is assembled around the tabbed preform 200, each of the preform extension pieces 202 may substantially fit within a corresponding recess 210. In some embodiments, the preform extension pieces 202 may all have substantially the same shape and/or size such that the they are agnostic to the corresponding recesses 210 (i.e., any preform extension piece 202 will fit in any recess 210). In other embodiments, the preform extension pieces 202 may have differing shapes and/or sizes such that each preform extension piece 202 specifically corresponds to a particular recess 210. As such, the tabbed preform 200 may be appropriately oriented with respect to the exterior barrier 102 and the first piece 102a and the second piece 102b, when brought together to form the exterior barrier 102, will secure the tabbed preform 200 to the exterior barrier 102.
In some embodiments, the preform extension pieces 202 may have a semicircular shape and may be arranged in a vertical orientation such that a flat edge of the semicircular shape contacts the exterior wall 201 of the preform extension piece 202. In addition, such a shape and vertical orientation corresponds to the shape and orientation of the recesses 210 in the exterior barrier 102. However, such a shape and vertical orientation is merely illustrative.

The plurality of beads 204 may generally provide an indicator of an upper limit for placement of the exterior barrier 102 on the tabbed preform 200. That is, the plurality of beads 204 may act as a stop mechanism that restricts the exterior barrier 102 from being placed above the plurality of beads 204 (such as between the plurality of beads 204 and the top surface 212 of the tabbed preform 200 and/or beyond the top surface 212 of the tabbed preform 200). As such, when the exterior barrier 102 is placed around the tabbed preform 200, the exterior barrier 102 may not extend beyond the location of the plurality of beads 204 because the extension of the plurality of beads 204 from the exterior wall 201 of the tabbed preform 200 results in a circumference that is too large to join the first piece 102a and the second piece 102b together. However, when the tabbed preform 200 is properly placed with respect to the exterior barrier 102, the first piece 102a and the second piece 102b may fit together to be joined around the tabbed preform 200.
While ten beads 204 are depicted in
As illustrated in
At step 410, the method may include providing the various pieces of the exterior barrier 102. For example, according to the embodiments described herein, step 410 may include providing the first piece 102a and the second piece 102b. In other embodiments, step 410 may include providing three or more pieces.
At steps 415 and 420, the first piece 102a and the second piece 102b of the exterior barrier 102 may be aligned with the tabbed preform 200. That is, the recess(es) 210 in the first piece 102a and/or the second piece 102b may be aligned with the corresponding preform extension pieces 202. In addition, the first piece 102a and the second piece 102b may be appropriately aligned with the beads 204. For example, the first piece 102a and the second piece 102b may be placed such that the beads 204 are located between the pieces 102 and the top surface 212 of the tabbed preform 200. In addition, some embodiments may be configured such that the pieces 102 may contact the beads 204.
At step 425, the first piece 102a and the second piece 102b may be sealed together around the tabbed preform 200. In some embodiments, the first piece 102a may be sealed to the second piece 102b via heating, application of an adhesive, and/or the like. In some embodiments, sealing the first piece 102a to the second piece 102b may cause the preform extension pieces 202 to adhere to the exterior barrier 102, thereby joining the exterior barrier 102 with the tabbed preform 200.
At step 430, the tabbed preform 200 may be formed into the interior barrier 104 inside the exterior barrier 102, thereby forming the multi-barrier bottle 100. While step 430 describes blow molding the tabbed preform 200, it should be understood that the present disclosure is not limited to such. That is, in some embodiments, other processes of forming the interior barrier 104 may be used, such as extruding the tabbed preform 200 or the like.
As illustrated above, various embodiments of multi-barrier container having a tabbed preform are disclosed. These embodiments may allow for an efficient use of materials, as well as allowing for the tabbed preform to be accurately oriented with respect to the first (e.g. outer) barrier in forming the bottle, thereby avoiding instances where malformation may occur because of a misalignment between the tabbed preform and the first barrier. While particular embodiments and aspects of the present disclosure have been illustrated and described herein, various other changes and modifications can be made without departing from the spirit and scope of the disclosure. Moreover, although various aspects have been described herein, such aspects need not be utilized in combination. Accordingly, it is therefore intended that the appended claims cover all such changes and modifications that are within the scope of the embodiments shown and described herein.
The present application claims priority to U.S. Provisional Patent Application Ser. No. 62/144,550, filed Apr. 8, 2015 and entitled “Bottle Preform,” which is incorporated by reference herein in its entirety.
