Figures 1 and 9 show an illustrative lid (such as lid 100) attached to an illustrative container (such as container 120). Lid 100 may have a skirt component 102, a closed top end 104, and / or a skirt end wall 172. Lid 100 may be attached to container 120 by means of a thread. Container 120 may define an internal volume, which may be filled with any product or fluid material (e.g., adhesives, lubricants, lotions, medications, shampoos, hair treatments, oral care products (such as toothpaste or mouthwash), edible products (such as ketchup or pickles), and other materials typically dispensed via tubes). The internal volume of container 120 may be any volume capable of holding fluid material, but preferably should be a volume that consumers would find acceptable for everyday use.The lid 100 can be configured to prevent and / or slow the flow of material from the container 120. While Figure 1 shows the container as an example of a mouthwash container, and Figure 9 shows the container as an example of a toothpaste container (e.g., tube), it should be understood that these examples are for illustrative purposes only and are not intended to be limiting. Figures 2-7 show different views of an illustrative lid 100 as it separates from a container. As shown in Figure 3, the lid 100 may include a skirt component 102 and / or a seal component 106 positioned on it. In one example, the seal component 106 may be centered within the skirt component 102, while in other examples, the seal component 106 may be offset from a central longitudinal axis of the lid 100. The skirt component 102 may be made of a metallic material, such as aluminum, steel, or another metal used in consumer products. In some examples, the skirt component 102 may also be made of another material (such as a plastic), and the metal may be formed around the other material. As shown in Figures 2 and 3, the skirt component 102 may include a side wall, such as an external annular side wall 103.The external side wall 103 can have an external surface and an internal surface (e.g., the internal surface 105 of the external annular side wall 103; Figure 4). The external annular sidewall 103 can define a skirt cavity 123 (Figures 4, 5). The skirt cavity 123 can extend along a skirt axis SA (Figure 3). In some examples, the skirt cavity 123 can have an open lower end. Rnzenn / eznz / E / YiAi 107. The open lower end 107 may be formed by the external annular side wall 103 in examples. The circumference of the open lower end 107 may be greater than the circumference of the external annular side wall 103, less than the circumference of the external annular side wall 103, or equal to the circumference of the external annular side wall 103. The open lower end 107 may be configured to receive a part of a vessel, such as the vessel 120. For example, the open lower end 107 may be configured to receive a neck of a vessel, a neck and shoulders of a vessel, and the like. Cap 100 may include sealing component 106. Sealing component 106 may be made of one or more types of materials. For example, sealing component 106 may be made of one or more plastic materials, one or more metallic materials, and the like. Sealing component 106 may be formed in one or more shape factors, which may include a side wall and an end wall. Sealing component 106 may be annular, square, triangular, etc. In the example where sealing component 106 is annular, it may include an annular seal side wall 111. The side wall of the sealing component 106 (for example, the annular seal side wall 111 of the sealing component 106) may be threaded. The threading may be located on an internal surface of the annular seal side wall 111, such as the threaded internal surface 108, although in some examples the thread may be formed in one or more locations on the annular seal side wall 111, such as on an external surface of the annular seal side wall 111. The threaded surface (for example, threaded internal surface 108) may be configured to mate with a threaded surface of a vessel, such as the threaded external surface of a vessel part. For example, the threaded internal surface 108 may be configured to mate with a threaded external surface 128 of a neck 124 of a vessel body 140 (Figure 10). As shown in Figure 4, the side wall of the annular seal 111 can define a cavity (e.g., the neck cavity 113). The neck cavity 113 can have a closed upper end 104 (Figure 3) and / or an open lower end 115 (Figure 4). The open lower end 115 can be configured to receive a vessel, such as the neck 124 of the vessel 120. The sealing component 106 can be coupled (e.g., mounted) to the skirt component 102, although in some examples the sealing component 106 and the skirt component 102 can be formed from a single component. The sealing component 106 can be located within the skirt component 102. For example, the sealing component 106 can be located within the skirt cavity 123. In such examples, the outer annular side wall 103 of the skirt component can circumscribe the annular seal side wall 111 of the sealing component 106. The skirt component 102 may consist of a stamped metal component, as described herein. The metal material may be any type of metal that can be used for a lid, such as aluminum, steel (for example, Rnzrnn / cznz / E / YiAi tin-plated steel), and the like. The sealing component 106 may be made of an injection-molded plastic material. For example, the sealing component 106 may be made of polypropylene, polyethylene, and the like. The sealing component 106 may be injection-molded separately from the skirt component 102 and / or friction-fitted to the skirt component 102. The skirt component 102 and / or the sealing component 106 may be a single monolithic component. As shown in Figure 3, the skirt component 102 and / or the seal component 106 may include an interference element. The interference element 115 of the seal component 106 may be coupled (e.g., mated) with one or more elements (e.g., elements of the skirt component 102). For example, interference element 115 of the seal component 106 can be paired with one or more interference elements 117 of the skirt component 102. Pairing interference elements 115 and 117 of the skirt component 102 and the seal component 106 can prevent movement between the skirt component 102 and the seal component 106. For example, pairing interference elements 115 and 117 of the skirt component 102 and the seal component 106 can prevent rotation (e.g., relative rotation) between the skirt component 102 and the seal component 106.The matching of the interference elements of skirt component 102 and seal component 106 can establish a friction fit between skirt component 102 and seal component 106. As shown in Figure 5, the skirt component 102 may include a side wall (e.g., inner annular side wall 109, outer annular side wall 103), a skirt end wall 172 (Figure 3), and / or an interference element 117. The inner annular side wall 109 may be surrounded by the outer annular side wall 103 of the skirt component 102. For example, the inner annular side wall 109 may be surrounded by the outer annular side wall 103 of the skirt component 102 such that an annular gap 119 (Figure 8) may exist between the inner and outer annular side walls of the skirt component 102. In one example, the skirt end wall 172, the inner annular side wall 109, and / or the outer annular side wall 103 of the skirt component 102 may extend downward from the skirt end wall 172.The interference element 117 of the skirt component 102 can be located on an inner surface of the inner annular side wall 109 of the skirt component 102. The interference element 115 of the seal component 106 can be located on an outer surface of the annular seal side wall 111. The sealing component 106 may include a seal end wall 134 (Figures 3, 6). The annular seal side wall 111 may extend downward from the seal end wall 134. The seal end wall 134 may have an annular flange portion 136 that extends circumferentially beyond the outer surface of the annular seal side wall 111. In one example, the annular flange portion 136 may be mated to a shoulder 162 (e.g., Rnzrnn / cznz / E / YiAi an annular shoulder; Figure 8) formed on the inner surface of the inner annular side wall 109 of the skirt component 102. As described herein and shown in Figure 8, the inner annular side wall 109 may be surrounded by the outer annular side wall 103. The outer annular side wall 103 surrounding the inner annular side wall 109 may form an annular space 119 between the inner annular side wall 109 and the outer annular side wall 103 of the skirt component 102. A skirt end wall 172 (e.g., an annular skirt end wall) may define an opening 101 (e.g., a center opening; Figure 3) in the skirt cavity 123. The inner annular side wall 109 and / or the outer annular side wall 103 of the skirt component 102 may extend downward from the skirt end wall 172. The seal end wall 134 may have a top surface and / or a bottom surface. The annular seal side wall 111 may extend downward from the bottom surface of the seal end wall 134. The seal component 106 may be mounted on the skirt component 102. For example, the seal component 106 may be mounted on the skirt component 102 to close the center opening 101 such that a top surface of the skirt end wall 172 and the top surface of the seal end wall (for example, each of a top surface of the skirt end wall and the top surface of the seal end wall) remain exposed. The annular seal sidewall 111 of skirt component 102 may extend downwards. For example, the annular seal sidewall 111 of skirt component 102 may extend downwards beyond a lower edge of the inner annular seal sidewall 109 of skirt component 102. The outer annular seal sidewall 103 of skirt component 102 may extend downwards. For example, the outer annular seal sidewall 103 of skirt component 102 may extend downwards beyond a lower edge of the annular seal sidewall 111 of skirt component 102. As described herein and shown in Figure 10, the lid 100 can be attached to the container 120. The container 120 can include a container body 140. The container body 140 can include a body part 132 and / or a neck 124. The body part 132 can define a chamber, such as a chamber for containing a product (e.g., a product chamber). In some examples, the body part 132 of the container body 140 can be a thermoformed bottle. The neck 124 of the container body 140 can have a threaded external surface. In some examples, the neck 124 can be formed from a plastic material, although other examples may include the neck 124 formed from one or more materials, such as plastic, metal, and the like. The neck 124 can define a passage, such as a passage 126. The passage 126 can be configured to allow a material to flow into the product chamber. Rnzenn / eznz / E / YiAi The lid 100 can be coupled to the container body 140. For example, the lid 100 can be coupled to the container body 140 by means of a threaded coupling between the threaded surface (for example, the outer surface) of the neck 124 of the container and the threaded surface (for example, the inner surface 108) of the lid 100. The coupling of the lid 100 and the container body 140 can result in the sealing component 106 sealing the passage 126. In some examples, the neck 124 can be located within (for example, at least partially within) the neck cavity 113 of the lid 100. The vessel body 140 may include a shoulder portion 122. The neck 124 of the vessel may extend upward from the shoulder portion 122. In some examples, a lower edge of the outer annular wall 103 of the skirt component 102 may be adjacent to the shoulder portion 122 of the vessel body 140. The body portion 132 of the vessel body 140 may be a collapsible tube, a container (such as a rigid or semi-rigid container), and the like. The vessel body 140 may include a multi-layered structure, such as a multi-layered laminated structure. A lower end of the vessel (for example, a collapsible tube) may be sealed. The neck 124 of the vessel may be coupled to an upper end of the collapsible tube. Figure 10 shows an illustrative multilayer structure 150 of a container. The multilayer structure can be blow-molded as a tube. As shown in Figure 10, the shoulder 122 of the container (e.g., the tube) can comprise a neck (such as neck 124). Neck 124 can have a passage 126 and threads 128 for attaching a closure, such as cap 100. The multilayer structure 150 can include two or more layers. For example, the multilayer structure 150 can include at least two coextruded layers. The multilayer structure 150 can include a plurality of layers, such as a plurality of coextruded layers. The plurality of layers may include an innermost layer 152, a first interleaved layer 154, and an outermost layer 158. In examples, the plurality of layers may include a second interleaved layer 156 arranged between the first interleaved layer 154 and the outermost layer 158. In examples, the first interlayer 154 can be placed between the innermost layer 152 and the outermost layer 158. An adhesive layer 153 can be placed between the innermost layer 152 and the first interlayer 154. An adhesive layer 155 can be placed between the first interlayer 154 and the second interlayer 156. The second interlayer 156 and the outermost layer 158 can be fused together, for example, by melting them (e.g., partially melting them) at an interface. The second interlayer 156 and the outermost layer 158 can consist of the same material and / or can be formed together during a coextrusion process. One layer of the multilayer structure can function as a barrier layer. For example, any one or more of the innermost layer 152, the first interleaved layer 154, the second interleaved layer 156, and the outermost layer 158 can function as a layer of Rnzrnn / cznz / E / YiAi barrier. In one example, the first interleaved layer can function as a flavor barrier, an oxygen barrier, or both. In another example, the innermost layer 152, the second interleaved layer, and / or the outermost layer 158 can function as a moisture barrier. The container and / or lid may be part of a packaged product. For example, a packaged product may include the container, the lid, and / or a material in the container's product chamber.
