Jars and related containers are used to provide a practical, convenient and means of containing makeup, creams, powders, emulsions and other products for consumers. Once the contents of the container have been fully utilized or the consumer is otherwise ready to dispose of the container, recycling is the most environmentally friendly and preferred disposable option. However, jars currently in distribution for consumer products are often difficult to recycle, e.g. they may have a PET plastic or glass bottom jar portion, a screw-on lid with plastic components, an inner plastic component with an outer metal shroud, metal vacuumized plastic, two piece construction that is difficult to separate, or otherwise are constructed in a manner that makes recycling the container more arduous, causing consumers to default to disposing of the containers in the trash, with attendant negative environmental impact.
Consequently, there is a need for more easily recyclable containers and methods of making the same.
The present disclosure relates to jars with improved recyclability.
For example, a jar comprising a jar assembly and a lid assembly is disclosed. The jar assembly includes an aluminum base and a first aluminum inner cup provided within a first cavity defined within the aluminum base. An outer thread is provided about an exterior surface of the aluminum base. The lid assembly includes an outer cap and a hoop provided on an interior surface of a cylindrical sidewall of the outer cap, wherein the hoop is a strip of material having opposite first and second ends, wherein the strip of material is formed into a hoop/ring structure with the first and second ends engaging each other, and then bonded to the interior surface of the cylindrical sidewall of the outer cap. An inner thread mateable with the outer thread is provided about an interior surface of the hoop. The lid assembly may also include a liner provided on an interior surface of a top sidewall of the outer cap for forming a seal with a top rim of the jar assembly.
A method of manufacturing jars of the present disclosure can comprise providing a strip of material having opposite ends, and then rolling or forming the strip of material such that the opposite ends engage each other and such that the strip of material defines a hoop/ring structure. The method may include bonding/adhering the hoop to the interior surface of the cylindrical sidewall of the outer cap. The method may further include bonding/adhering the liner to the interior surface of the top sidewall of the outer cap. The method may further include coating the interior surfaces of the jar assembly and/or anodizing an exterior surface of the jar.
A lid assembly is provided herein. The lid assembly may include an outer lid and an inner lid provided in an interior cavity of the outer lid. The inner lid may include a first portion and a second portion having smaller diameter with the first portion such that the cylindrical sidewall of the first portion contacts the cylindrical sidewall of the outer lid. The second portion of the inner lid may have a top wall that contacts the top wall of the outer lid, and the first portion of the inner lid may have an annular shaped upper wall that is spaced from the top wall of the outer wall.
The following figures are included to illustrate certain aspects of the present disclosure, and should not be viewed as exclusive embodiments. The subject matter disclosed is capable of considerable modifications, alterations, combinations, and equivalents in form and function, without departing from the scope of this disclosure.
The present disclosure is related to jars and containers and, more particularly, to the manufacture of readily recyclable jars and containers.
Currently, standard construction for jars for consumer products for household use, e.g. makeup jars for creams, powders and emulsion-type products, have a PET plastic or a glass bottom jar portion and a screw-on plastic lid, or a plastic lid with metal shroud. In order to recycle these commonly used jars, the consumer must unscrew the jar and can sometimes place the jar in a PET or glass bin in order for the jar to be recycled, but the lid remains difficult to recycle.
The jar 100 includes a lid assembly 102 and a jar assembly 104 (or base assembly 104). The lid assembly 102 may be fastened or secured to the jar assembly 104. However, the lid assembly 102 may be detached from the jar assembly 104 to access an internal cavity 500 (
The jar 100 may be made entirely (or predominantly) from a metallic material; however, non-metallic materials may be utilized. In some examples, the lid assembly 102 and the jar assembly 204 are made of the same material, whereas in other examples, they are made from one or more dissimilar materials. In one example, the inner cap 202a and the outer cap 202b of the lid assembly 102 and the inner cup 204a and the outer cup 204b of the jar assembly 104 are all comprised of aluminum. Fabricating the jar 100 from (predominantly) the same metallic material will improve its recyclability. Also, fabricating the jar 100 from predominantly a metallic material provides it with a premium metallic appearance, thereby further enhancing its ability to be utilized in applications where aesthetics are desirable.
The jar 100 may also have some nonmetallic components (e.g., plastic components) and still be recyclable. For example, either or both of the inner cap 202a and/or the inner cup 204a of the lid assembly 102 and the jar assembly 104, respectively, may be made from a plastic material. In examples where the jar 100 includes one or more plastic components, such plastic components may be installed in a manner permitting the end user to easily remove it before disposal, to enhance recyclability of the jar 100. For example, the inner cup 204a of the jar assembly 104 may be a plastic liner that is press fit within the outer cup 204b in a manner permitting the end user to easily remove it from the outer cup 204b before disposing of the jar assembly 104. In some examples, the jar 100 includes one or more plastic components that need not be removed prior to disposal as such plastic components will be burned up in the metal recycling process. In some examples, the lid assembly 102 includes a gasket to help form a seal when attached on the jar assembly 104. The gasket may be provided on either or both of the lid assembly 102 and the jar assembly 104 to form a seal there-between. In some examples, an additional liner is provided within the inner cap 202a and/or inner cup 204a, such as a polymeric liner or removable and replaceable liner; and in some examples, a series of liners may be so provided such that they are serially removed after each use to provide a clean surface for a subsequent use.
A coating may be applied to the lid assembly 102 and/or the jar assembly 104. Various types of coating may be utilized, for example, a polymeric coating and/or a ceramic spray, and such coatings may be applied after assembly of the jar 100 or pre-coated materials may be utilized to manufacture the jar 100. In some examples, a coating is applied to interior surfaces 602, 604 (
Where metallic materials are utilized to form the jar 100, they may be anodized, for example, external surfaces 502, 504 (
Various techniques may be utilized to form the inner cap 202a and the outer cap 202b of the lid assembly 102 and the inner cup 204a and the outer cup 204b of the jar assembly 104. For example, any or all may be formed via a deep drawing, impact extrusion, roll forming, eyelet stamping etc.
As shown in
Optionally, the primary metal material may be pre-coated, such a by pre-coating the aluminum alloy, pre-anodizing the metal, or plating. Accordingly, the manufacturing process may include an optional step of precoating the selected material. In some embodiments, the selected material has no precoating. However, Aluminum alloys may be pre-coated with an inorganic barrier-type corrosion inhibitor, e.g., a composition comprising clay particles. In some embodiments, the selected material is pre-anodized. Pre-anodizing the material involves an electrochemical process that converts the metal surface into a decorative, durable, corrosion-resistant, anodic oxide finish. A typical chemical treatment process may involve removing dirt and oils, such as by treatment with an inhibited acid or alkaline cleaner, deoxidizing the material in strong acidic solution to remove natural oxides or heat-treat scale, and chemical etching or brightening. Strong acids or bases may be used to etch the material in order to provide a uniform, matte finish. Brightening, also known as micro-leveling or micro-smoothing, may be achieved by either chemical or electrochemical means, as would be known by one skilled in the art. Alternatively, the selected material may be plated, such as to increase corrosion protection, provide greater wear resistance or to enhance the appearance of a product. Electroplating or an autocatalytic reaction may be used. The plating material may be any commonly known in the art, such as zinc, tin, magnesium, silicon or other metals or metalloids.
Thereafter, the manufacturing process includes a metal forming step. The metal is formed to make the jar assembly and lid assembly, such as by deep draw, impact extrusion, roll forming or eyelet stamping. Deep drawing involves a hydraulic or mechanical press pushing the metal sheet via an appropriately shaped punch into a matching die. Impact extrusion utilizes a punch to press a slug at high velocity and force into the appropriately shaped die or mold. Roll forming passes the metal through a continuous bending operation to bend the metal into the desired shape of a jar assembly or lid.
The jar assembly and lid assembly may optionally comprise a liner material and/or sealing material, by way of non-limiting examples a gasket, foam liner, or overmolded gasket. According, the manufacturing process may further include an optional step of providing a liner and/or seal.
The manufacturing process then includes the step of assembling the lid assembly. The assembly of the lid assembly, or the combining of the inner cap with the outer cap, may be carried out by means of adhesive bonding, mechanical bonding, welded bonding, or other methods known to one skilled in the art.
Following the step of assembling the jar assembly, the manufacturing process may include an optional step of installing a cup within the jar assembly. For example, a plastic cup may be installed within the jar assembly. In the illustrated example, the step of installing a cup is provided a final step; however, in other non-illustrated steps, the jar may be further subject to final decorating or design steps, including painting, etching, branding, adding graphics or decals, or providing other indicia as may be desirable for the final end use application.
In the illustrated example, the lid assembly 1200 is a three-piece design. As shown, the lid assembly 1200 includes an inner hoop 1202a, an outer cap 1202b, and a liner 1202c. The outer cap 1202b defines an internal cavity within which the inner hoop 1202a and the liner 1202c may be provided. The lid assembly 1200, when assembled together, and the jar assembly 104 may be attachable via mating threads. In the illustrated example, a thread 1302 of the lid assembly 1200 mates with the corresponding thread 304 of the jar assembly 104 (which is provided on the outer diameter of the outer cup 204b of the jar assembly 104) when the lid assembly 1200 is provided on the jar assembly 104. Here, the thread 1302 is provided on the hoop 1202a, winding around an interior sidewall thereof, and covered by the outer cap 1202b such that the thread 1302 is not visible unless viewing an internal cavity of the lid assembly 1200 when unattached from the jar assembly 104. The corresponding thread 304 of the jar assembly 104 is thus visible and exposed when the jar is unassembled, but hidden from view when assembled with the lid assembly 1200 is secured over the jar assembly 104. In some embodiments, a secondary closure mechanism may be utilized, in addition to, or instead of, the corresponding threads 1302, 304, for example, a magnetic closure and or interference fit closure for securing the lid assembly 1200 and the jar assembly 104 together.

The hoop 1202a may be formed from a single strip of material 1610 having a first end 1612a and a second end 1612b opposite the first end 1612a. The strip 1610 may be rolled or formed into the rim/hoop like structure, and then first end 1612a and the second end 1612b of the strip 1610 may be joined together at a joint 1614. In the illustrated embodiment, the joint 1614 is a dove tail joint, with the first end 1612a including a tail 1616a (
The liner 1202c may function as a seal when the lid assembly 1200 is screwed onto the jar assembly 104. In embodiments, the liner 1202c may be a piece of soft compressible material, such as polyethylene (PE) foam or paper pulp. Where utilized, the liner 1202c is used to form a seal between the lid assembly 1200 and the jar assembly 104. For example, when the lid assembly 1200 is screwed onto the jar assembly 104, an upper rim 900 (see
To assemble the lid assembly 1200, the strip of material 1610 is formed into the ring like shape and the ends 1612a, 1612b are attached or joined together at the joint 1614 such that the strip of material 1610 defines the hoop 1202a. Then, adhesive is applied to an inner surface 1502 of a cylindrical sidewall portion 1504 of the outer cap 1202b (
Also disclosed herein is a method of forming a jar including the lid assembly 1200. The method may include a step of forming the lid assembly 1200, which may include a step of providing the outer cap 1202b, which may further include forming the outer cap 1202, for example, via deep drawing, impact extrusion, roll forming, eyelet stamping etc. The step of forming the lid assembly 1200 may include providing the strip of material 1610 and forming the strip of material 1610 into the hoop 1202a (or the step of forming the hoop 1202a from the strip of material 1610), for example, but rolling the strip of material 1610 into the hoop 1202a. The method may then include a step adhering or bonding the hoop 1202a to the inner surface 1502 of the cylindrical sidewall portion 1504 of the outer cap 1202b. The method may also include a step adhering or bonding the liner 1202c to the inner surface 1512 the outer cap 1202b, and this step may be performed before, after, or substantially simultaneously as the step of bonding the hoop 1202a to the outer cap 1202b. In embodiments, the outer cap 1202b is formed via deep drawing and, in such embodiments, the aluminum base and the first aluminum inner cup of the jar assembly 104 may be formed via the same or different method. In embodiments, the outer cap 1202b is formed via impact extrusion and, in such embodiments, the aluminum base and the first aluminum inner cup of the jar assembly 104 may be formed via the same or different method.
The hoop 1202a and the outer cap 1202b may be formed of various materials. In embodiments, the hoop 1202a and the outer cap 1202b are each aluminum. In embodiments, the hoop 1202a and/or the outer cap 1202b are anodized. In embodiments, an FDA-approved polymeric coating is applied to the inner surface 1512 of the top sidewall portion 1514 and/or to an inner surface 1522 (
In the illustrated example, the lid assembly 2100 is a three-piece design. As shown, the lid assembly 2100 includes an inner lid 2102a, an outer cap 2102b, and a seal 2102c. The inner lid 2102a and/or the outer lid 2102b may be made from various materials, such as aluminum. In embodiments, exposed surfaces of the inner lid 2102a and/or the outer lid 2102b includes a coating applied thereto, such an FDA-approved polymeric coating. In embodiments, the coating is an epoxy coating.
The outer cap 2102b defines an internal cavity within which the inner lid 2102a and the seal 2102c may be provided. In the illustrated embodiment, the inner lid 2102a also defines an internal cavity within which the seal 2102c may be provided. The lid assembly 2100, when assembled together, may be attached to a neck of a jar assembly or container via mating threads. In the illustrated example, a thread 2104 of the lid assembly 2100 mates with the corresponding thread of a jar assembly (which is provided on an outer diameter/surface of the jar assembly) when the lid assembly 2100 is provided on the jar assembly. Here, the thread 2104 is provided on the inner lid 2102a, winding around an interior sidewall thereof, and covered by the outer cap 2102b such that the thread 2104 is not visible unless viewing an internal cavity of the lid assembly 2100 when unattached from the jar assembly. The corresponding thread of the jar assembly is thus visible and exposed when the jar is unassembled, but hidden from view when assembled with the lid assembly 2100 is secured over the jar assembly. In some embodiments, a secondary closure mechanism may be utilized, in addition to, or instead of, the corresponding threads 2104, for example, a magnetic closure and or interference fit closure for securing the lid assembly 2100 and the jar assembly together.
In the illustrated embodiment, the inner cap 2102a includes a first portion 2106a and a second portion 2106b. The first portion 2106a has a first diameter and the second portion 2106b has a second diameter that is smaller than the first diameter of the first portion 2106a. The inner cap 2102a includes an upper surface 2108 which is provided on the second portion 2106b. The inner cap 2102a also includes an upper facing annular surface 2110 which is provided on the first portion 2106a and which surrounds the second portion 2106b. When the inner cap 2102a is assembled within the outer cap 2102b, the upper surface 2108 will contact and abut an inner surface 2112 of the outer cap 2102b, and the upper facing annular surface 2110 will be spaced from the inner surface 2112 of the circular top wall of the outer cap 2102b. In embodiments, an adhesive 2114 may be utilized to secure the upper surface 2108 to the inner surface 2112.
The inner cap 2102a includes a first side surface 2116 defined on the first portion 2106a and a second side surface 2118 defined on the second portion 2106b. The thread 2104 is provided on the second side surface 2118 of the second portion 2106b. When the inner cap 2102a is assembled within the outer cap 2102b, the thread 2104 will be partially hidden, as it will only be visible when viewing the interior cavity of the inner lid 2102a, but otherwise covered and hidden by the outer cap 2102b. Also, when the inner cap 2102a is assembled within the outer cap 2102b, the first side surface 2116 will contact and abut an inner side surface 2120 of the outer cap 2102b. In embodiments, the adhesive 2114 may also or instead be utilized to secure the first side surface 2116 to the inner side surface 2120. Because the second diameter of the second portion 2106b is smaller than the first diameter of the first portion 2106a, the second side surface 2118 is spaced apart from the inner side surface 2120 of the outer cap 2102b. The seal 2102c may be adhered to an inner surface 2124 of the second portion 2106b of the inner lid 2102a, wherein the inner surface 2124 is opposite the upper surface 2108. In embodiments, the adhesive 2114 is utilized to secure the seal 2102c to the inner lid 2102a. In embodiments, the seal 2102c is made of a foam material for engaging and sealing the nozzle of a bottle/container/jar on which the lid assembly 2100 is attached.
