Description

Technical Field

[0001] The present application relates to the field of cosmetic technology, and in particular to a brush head for an eyelash brush and an eyelash brush. Background Art

[0002] An eyelash brush is one of the important tools for eye makeup. Dip the brush in mascara and use it to apply a base to the eyelashes, curl and shape them, and extend the eyelashes, making them thick, distinct, and naturally long.

[0003] At present, the brush heads of mascara brushes are mostly cylindrical or flat. The cylindrical brush head has a large variation in the slope of the bristles, which cannot hold the eyelashes well and apply mascara evenly on the eyelashes. The flat brush head has a small contact area with the eyelashes, and the eyelash brushing step needs to be repeated many times, resulting in uneven application of mascara on the eyelashes and an unnatural makeup effect. Utility Model Content

[0004] The present application provides a brush head and an eyelash brush for an eyelash brush, which can achieve a more uniform and natural eyelash makeup effect.

[0005] In order to achieve the above objectives, the main technical solutions adopted in this application include:

[0006] In a first aspect, an embodiment of the present application provides a brush head for an eyelash brush, comprising a brush rod, a plurality of first bristles and a plurality of second bristles, the circumferential surface of the brush rod comprising a first side wall and a second side wall, along the length direction of the brush rod, the projection of the first side wall is arc-shaped and bulges away from the center line of the brush rod, and the second side wall is constructed as a plane; a plurality of first bristles are arranged on the first side wall, and along the length direction of the brush rod, the plurality of first bristles are arranged at intervals; a plurality of second bristles are arranged on the second side wall, and along the length direction of the brush rod, the plurality of second bristles are arranged at intervals.

[0007] The brush head proposed in the embodiment of the present application has a first side wall with an arc structure and a second side wall with a planar structure. The first side wall with an arc structure can make the first bristles fit the curvature of the eyelashes more closely, easily extend into the roots of the eyelashes, and create a naturally long eyelash makeup effect; the second side wall with a planar structure can enable the second bristles to comb the eyelashes, adjust the direction of the eyelashes, and enhance the curling effect. The combination of the first side wall and the second side wall can achieve a naturally long, curled, and thick makeup effect for the eyelashes.

[0008] Optionally, along the length direction of the brush rod, the projection of the outer contour of the first bristles is arc-shaped.

[0009] In the above embodiment, when brushing eyelashes, the plurality of first bristles configured as arc surfaces have good combing properties when combing the eyelashes, and the mascara between the plurality of first bristles is brushed onto the eyelashes, achieving a natural and distinct makeup effect.

[0010] Optionally, the ends of the plurality of first bristles away from the first side wall jointly form a first contour surface, and the first contour surface is configured as an arc surface that is concave toward a center line of the brush rod.

[0011] In the above embodiment, the first contour surface is recessed in the middle, and the gaps between the multiple first bristles are fine and stable, thereby creating a more distinct and naturally long eyelash makeup effect. The shorter first bristles are less likely to rub against other skin around the eyes, and can better fit the roots of the eyelashes, making the eye makeup effect natural and more obvious.

[0012] Optionally, the ends of the plurality of first bristles away from the first side wall jointly form a first contour surface, and the first contour surface is configured as a cylindrical surface.

[0013] In the above embodiment, the first contour surface constructed as a cylindrical surface can tightly wrap the arc structure of the eyelashes. When combing, the first bristles can evenly apply curling force from the root to the tip, reducing the bending or tangling of the eyelashes caused by insufficient contact between the first bristles and the eyelashes, reducing mascara accumulation, and thus reducing the "fly legs" phenomenon.

[0014] Optionally, the ends of the plurality of first bristles away from the first side wall jointly construct a first contour surface, the first contour surface includes a first sub-contour surface and a second sub-contour surface connected, the first sub-contour surface is constructed as a cylindrical surface, and the second sub-contour surface is constructed as an arc surface concave toward the center line of the brush rod.

[0015] In the above embodiment, the cylindrical surface tightly wraps around the eyelashes, reducing bending or tangling caused by insufficient contact between the first bristles and the eyelashes, reducing mascara buildup, and thus reducing the "fly-leg" phenomenon. The curved surface, which is concave toward the centerline of the brush handle, better supports the ends of the eyelashes, allowing mascara to be applied to them, thereby creating a naturally elongated effect.

[0016] Optionally, the length of the first bristles is shorter than the length of the second bristles.

[0017] In the above embodiment, the first brush bristles with shorter length can carry a more appropriate amount of mascara to create a more distinct and naturally long eyelashes makeup effect, and the second brush bristles with longer length can carry more mascara to create a thicker and curled eyelashes makeup effect.

[0018] Optionally, the second sidewall includes a first sub-sidewall and a second sub-sidewall, the first sub-sidewall is adjacent to the second sub-sidewall and is arranged at an angle; the second bristles are arranged on the first sub-sidewall and the second sub-sidewall.

[0019] In the above embodiment, the depth of the tooth groove between two adjacent second bristles is large, and the eyelashes can be completely stuck in the tooth groove for combing, thereby creating a thick eyelash makeup effect and making the ends of the eyelashes more slender.

[0020] Optionally, the second side wall includes a first sub-side wall and a second sub-side wall, the first sub-side wall is adjacent to the second sub-side wall and is arranged at an angle; the second bristles include first sub-bristles and second sub-bristles, the first sub-bristles are arranged on the first sub-side wall, and the second sub-bristles are arranged on the second sub-side wall.

[0021] In the above embodiment, the gap between the first sub-bristles and the second sub-bristles can carry mascara. When using the first sub-bristles and the second sub-bristles to comb eyelashes, the eyelashes stuck in the gap between the first sub-bristles and the second sub-bristles can be evenly dipped in the mascara in the gap, thereby making the painted eyelashes more evenly thicker.

[0022] Optionally, along the length direction of the brush rod, a plurality of the first sub-bristles and a plurality of the second sub-bristles are staggered.

[0023] In the above embodiment, the staggered bristles can evenly comb the roots of multiple eyelashes, and the tips of multiple eyelashes will fall into the same bristle groove, so that the multiple eyelashes are aggregated into a cluster at the end of the eyelashes, thereby achieving a clustered eyelash makeup effect.

[0024] Optionally, the ends of the plurality of second bristles away from the second side wall form a first contour line, and the first contour line is configured as a straight line segment.

[0025] In the above embodiment, the plurality of second bristles with straight outer contours carry mascara evenly, which can form stable lateral coverage when applying to eyelashes, is suitable for evenly applying to large areas, and can evenly distribute the mascara in the middle section of the eyelashes, ensuring basic density.

[0026] Optionally, a plurality of the second bristles together form a first contour line at one end away from the second side wall, the first contour line including a first segment and a second segment connected, the first segment being a straight line segment, the second segment being an arc segment convex toward a center line away from the brush rod, or the second segment being a arc segment concave toward a center line close to the brush rod.

[0027] When applying lashes, the multiple second bristles corresponding to the first section create stable horizontal coverage, suitable for evenly applying over a large area, evenly distributing the cream in the middle of the lashes, and ensuring a thick foundation. When applying lashes with the outward-protruding second section, the second bristles better conform to the natural curvature of the lashes at the end of the eye, allowing the outer bristles to reach the corners of the eye and reduce missed areas. When applying lashes with the concave second section, the second bristles focus on the base of the lashes, wrapping the lashes with the concave arc, making the cream at the base of the lashes thicker. At the same time, the bristles on both sides help separate the lashes, creating a "clearly defined" and thickened effect.

[0028] Optionally, the ends of the plurality of second bristles away from the second side wall form a first contour line, and the first contour line is configured as an arc segment concave toward a center line of the brush rod.

[0029] In the above embodiment, the curvature of the first outer contour constructed by multiple second bristles fits the eye curve better, the length of the second bristles at the end of the brush head is greater than the length of the second bristles in the middle of the brush head, and the second bristles at the end of the brush head can be used to brush the eyelashes at the beginning and end of the eyes, thereby making the overall makeup more refined and three-dimensional.

[0030] Optionally, the ends of the plurality of second bristles away from the second side wall form a first contour line, and the first contour line is configured as an arc segment convex away from the center line of the brush rod.

[0031] In the above embodiment, the middle parts of the multiple second bristles form an outward-convex structure, which can reduce the second bristles from rubbing against the eyelids when applying mascara, and the depth between two adjacent bristles corresponding to the outward-convex second bristles is deeper, so more mascara is carried, which has better combing properties and can create thick, long and curled eyelashes.

[0032] Optionally, along a first direction, the first side wall and the second side wall are relatively arranged on two sides of the brush rod, and the first direction is perpendicular to the length direction of the brush rod.

[0033] In the above embodiment, during use, the plurality of first bristles arranged on the first side wall and the plurality of second bristles arranged on the second side wall do not interfere with each other.

[0034] Optionally, the brush rod, the plurality of the first bristles and the plurality of the second bristles are constructed as a flat structure.

[0035] In the above embodiment, the flat first bristles have a gentler slope from the middle to both sides, and the slope of uniform height is longer. When brushing the eyelashes, the longer slope can well support the ends of the eyelashes when brushing upwards, allowing the ends of the eyelashes to be better loaded with material, making the entire eyelash makeup effect more slender and curled.

[0036] Optionally, the brush rod, the first bristles, and the second bristles are all made of stainless steel.

[0037] In the above embodiment, the surface of the stainless steel material is smooth, not easy to absorb dirt and bacteria, and is easy to clean, thereby improving eye hygiene.

[0038] In a second aspect, an embodiment of the present application further provides an eyelash brush, comprising the brush head and brush handle described in any of the above embodiments, wherein the brush handle is connected to one end of the brush rod along the length direction.

[0039] The mascara brush comprises the brush head described in any one of the above embodiments and has the beneficial effects of the brush head described in any one of the above embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0061] First, reference Figures 1 to 10 The embodiment of the present application provides a brush head 100 for an eyelash brush, the brush head 100 includes a brush rod 110, a plurality of first bristles 120 and a plurality of second bristles 130, the circumference of the brush rod 110 includes a first side wall 111 and a second side wall 112, along the length direction A of the brush rod 110, the projection of the first side wall 111 is arc-shaped and protrudes away from the center line of the brush rod 110, and the second side wall 112 is constructed as a plane; the plurality of first bristles 120 are arranged on the first side wall 111, and along the length direction A of the brush rod 110, the plurality of first bristles 120 are arranged at intervals; the plurality of second bristles 130 are arranged on the second side wall 112, and along the length direction A of the brush rod 110, the plurality of second bristles 130 are arranged at intervals.

[0062] refer to Figure 10 The first side wall 111 is set to be an arc that bulges outward away from the center line of the brush rod 110, and the first bristles 120 are arranged on the first side wall 111. This arc setting can make the first bristles 120 better adapt to the natural curvature of the eyelashes, and can closely fit various parts from the root to the tip of the eyelashes. It is particularly suitable for outlining detailed areas such as the tail of the eye or the lower eyelashes, reducing blind spots in application, and allowing mascara to evenly cover each eyelash.

[0063] The second side wall 112 is constructed as a planar structure, and the second bristles 130 are arranged on the second side wall 112. The planar structure of the second side wall 112 can provide a more stable contact area for the second bristles 130, which is convenient for combing the eyelashes horizontally or vertically, reducing the clumping of eyelashes, and shaping the eyelashes to make the makeup effect more natural.

[0064] The brush head 100 proposed in the embodiment of the present application has a first side wall 111 with an arc structure and a second side wall 112 with a planar structure. The first side wall 111 with an arc structure can make the first bristles 120 fit the curvature of the eyelashes more closely, easily reach the roots of the eyelashes, and create a naturally long eyelash makeup effect; the second side wall 112 with a planar structure can enable the second bristles 130 to comb the eyelashes, adjust the direction of the eyelashes, and enhance the curling effect. The combination of the first side wall 111 and the second side wall 112 can achieve a naturally long, curled, and thick eyelash makeup effect.

[0065] It should be understood that since the brush rod 110 is provided with both an arc-shaped first side wall 111 and a planar second side wall 112, the first side wall 111 and the second side wall 112 are arranged on the circumference of the brush head 100, and the first side wall 111 occupies a partial area on the circumference of the brush rod 110, that is, along the circumference of the brush rod 110, the first side wall 111 is constructed as an arc. In other words, along the length direction of the brush rod 110, the projection of the first side wall 11 is an arc.

[0066] Optionally, the projection of the outer contour of the first bristles 120 along the length direction A of the brush rod 110 is an arc. The projection of the outer contour of the first bristles 120 is an arc. The first bristles 120 extend outward from the first side wall 111 and have an arc-shaped structure along the circumference of the brush rod 110. The arrangement direction of the first bristles 120 can be perpendicular to the length direction A of the brush rod 110, or the arrangement direction of the first bristles 120 can be arranged at an angle to the length direction A of the brush rod 110, such as the first bristles 120 being arranged on the first side wall 111 in a spiral shape. The gaps between the multiple first bristles 120 in the arc-shaped structure can scrape an appropriate amount of mascara. When brushing the eyelashes, the multiple first bristles 120 have good combing properties when combing the eyelashes, and the mascara between the multiple first bristles 120 is brushed onto the eyelashes, achieving a natural, distinct makeup effect.

[0067] Optionally, refer to Figure 1 、 Figure 3 、 Figures 5 to 8 The ends of the plurality of first bristles 120 away from the first side wall 111 jointly form a first contour surface 140 , and the first contour surface 140 is constructed as an arc surface that is concave toward the center line of the brush rod 110 .

[0068] The first contour surface 140 is constructed as an arc surface that is concave toward the center line of the brush rod 110. That is, along the length direction A of the brush rod 110, the length of the first bristles 120 at both ends of the first side wall 111 is greater than the length of the first bristles 120 in the middle of the first side wall 111. The first bristles 120 corresponding to the concave area in the middle of the first contour surface 140 can carry a relatively appropriate amount of mascara. The gaps between the multiple first bristles 120 are fine and stable, thereby creating a more distinct and naturally long eyelash makeup effect. The shorter first bristles 120 are not easy to rub against other skin around the eyes, and can better fit the roots of the eyelashes to make the eye makeup effect natural and more obvious.

[0069] Optionally, the ends of the plurality of first bristles 120 facing away from the first sidewall 111 collectively form a first contoured surface 140, which is configured as a cylindrical surface (not shown). The cylindrical first contoured surface 140 can tightly wrap around the curved structure of the eyelashes. In particular, the spiral arrangement of the first bristles 120 allows the first bristles 120 to evenly apply a curling force from root to tip during combing, reducing eyelash bending or tangling caused by insufficient contact between the first bristles 120 and the eyelashes, reducing mascara buildup, and thus reducing the "fly-legged" phenomenon.

[0070] Optionally, multiple first bristles 120 together form a first contour surface 140 at one end away from the first side wall 111, and the first contour surface 140 includes a first sub-contour surface and a second sub-contour surface (not shown in the figure) connected to each other. The first sub-contour surface is constructed as a cylindrical surface, and the second sub-contour surface is constructed as an arc surface concave toward the center line of the brush rod 110.

[0071] The first and second sub-contour surfaces are interconnected to form the outer contours of the plurality of first bristles 120. The cylindrical surface tightly wraps around eyelashes, reducing bending or tangling caused by insufficient contact between the first bristles 120 and the eyelashes, and reducing mascara buildup, thereby reducing the "fly-leg" effect. The curved surface, which is concave toward the centerline of the brush rod 110, better supports the ends of the eyelashes during application, allowing mascara to be applied more easily to the ends, creating a naturally elongated effect.

[0072] The shorter first brush 120 can carry a moderate amount of mascara for a more defined, naturally long eyelash effect, while the longer second brush 130 can carry a larger amount of mascara for a thicker, curled eyelash effect. Users can freely choose to use the first brush 120, the second brush 130, or a combination of the first and second brushes 120, 130, based on their makeup preferences and eye conditions, to create different eyelash effects. For example, use the first brush 120 for a base application and then use the second brush 130 for a thicker, curled effect. Alternatively, use the second brush 130 first for a thicker, curled effect and then use the first brush 120 for a longer, longer effect, providing a rich and diverse makeup experience.

[0073] In an optional embodiment, the distance between two adjacent first bristles 120 is smaller than the distance between two adjacent second bristles 130. The second bristles 130 with a larger distance can carry more mascara, thereby creating a thick eyelash makeup effect.

[0074] Optionally, refer to Figure 2 The second side wall 112 includes a first sub-side wall 1121 and a second sub-side wall 1122 , the first sub-side wall 1121 and the second sub-side wall 1122 are adjacent to each other and are arranged at an angle; the second bristles 130 are arranged on the first sub-side wall 1121 and the second sub-side wall 1122 .

[0075] Only one row of second bristles 130 is provided on the second side wall 112. The length of the second bristles 130 is greater than that of the first bristles 120. The depth of the tooth groove between two adjacent second bristles 130 is large, so that the second bristles 130 have better combing properties and can completely fit the eyelashes into the tooth groove for combing, thereby creating a thick eyelash makeup effect and making the ends of the eyelashes more slender.

[0076] Optionally, refer to Figure 4 and Figure 10 The second side wall 112 includes a first sub-side wall 1121 and a second sub-side wall 1122. The first sub-side wall 1121 is adjacent to the second sub-side wall 1122 and is arranged at an angle. The second bristles 130 include first sub-bristles 131 and second sub-bristles 132. The first sub-bristles 131 are arranged on the first sub-side wall 1121, and the second sub-bristles 132 are arranged on the second sub-side wall 1122.

[0077] Along the circumference of the brush rod 110, there is a gap between the first sub-bristles 131 and the second sub-bristles 132, and the gap can carry mascara. When using the first sub-brush 131 and the second sub-brush 132 to comb the eyelashes, the eyelashes stuck in the gap between the first sub-brush 131 and the second sub-brush 132 can be evenly dipped in the mascara in the gap, so that the brushed eyelashes are more evenly thickened. Exemplarily, the width of the end of the first sub-bristle 131 connected to the first sub-side wall 1121 along the circumferential direction of the brush rod 110 is greater than the width of the free end of the first sub-bristle 131, and the width of the end of the second sub-bristle 132 connected to the second sub-side wall 1122 along the circumferential direction of the brush rod 110 is greater than the width of the free end of the second sub-bristle 132. Therefore, from the root of the bristles to the free end, the gap between the first sub-bristle 131 and the second sub-bristle 132 along the circumferential direction of the brush rod 110 gradually increases. The gap can carry more mascara, so that the eyelashes stuck in the gap can be dipped in more mascara, making the eyelashes more uniform and thicker.

[0078] Optionally, refer to Figure 3 、 Figure 4 、 Figure 6 and Figure 8 Along the length direction A of the brush rod 110, a plurality of first sub-bristles 131 and a plurality of second sub-bristles 132 are staggered. That is, the arrangement position of the second sub-bristles 132 corresponds to the gap between two adjacent first sub-bristles 131. The staggered arrangement of the plurality of first sub-bristles 131 and the plurality of second sub-bristles 132 can better control the depth of the gap between two adjacent bristles and the width of the gap along the length direction of the brush rod 110. A deeper and wider gap can carry more mascara. When applying mascara, more mascara can be applied to the roots of the eyelashes. The width between two adjacent bristles along the circumference of the brush rod 110 is smaller. Along the circumference of the brush rod 110, the length of the gap between two adjacent bristles is smaller, and the mascara carried is relatively less, thereby reducing the overall makeup effect caused by excessive mascara applied to the ends of the eyelashes.

[0079] In addition, the multiple first sub-bristles 131 and the multiple second sub-bristles 132 are staggered, which can comb the roots of multiple eyelashes, and the tips of multiple eyelashes will fall into the gap between the same two adjacent bristles, so that the multiple eyelashes are aggregated into a cluster at the end of the eyelashes, thereby achieving a clustered eyelash makeup effect.

[0080] Optionally, refer to Figure 1 and Figure 3 The ends of the plurality of second bristles 130 away from the second side wall 112 form a first contour line 150 , and the first contour line 150 is configured as a straight line segment.

[0081] The multiple second bristles 130 with straight outer contours carry mascara evenly, which can form stable horizontal coverage when brushing eyelashes. It is suitable for uniform brushing over a large area and can evenly distribute the mascara in the middle section of the eyelashes to ensure the basic density.

[0082] Optionally, the ends of the plurality of second bristles 130 away from the second side wall 112 jointly construct a first contour line 150, and the first contour line 150 includes a first segment and a second segment (not shown in the figure) connected, the first segment is constructed as a straight line segment, and the second segment is constructed as an arc segment convex toward the center line away from the brush rod 110 or the second segment is constructed as an arc segment concave toward the center line close to the brush rod 110.

[0083] The first section, with its straight outer contour, carries mascara evenly. Using the multiple second bristles 130 corresponding to the first section, when applying mascara to the eyelashes, stable horizontal coverage is achieved, making it suitable for evenly applying to a large area. This evenly distributes the mascara in the middle of the eyelashes, ensuring a consistent foundation of volume. When applying mascara to the eyelashes using the multiple second bristles 130 corresponding to the second section, if the second section is constructed as an outwardly convex arc, the second bristles 130 can better conform to the natural curvature of the eyelashes at the end of the eye, allowing the outer bristles to reach the corners of the eye and reduce missed areas. If the second section is constructed as an inwardly concave arc, the second bristles 130 can focus on the base of the eyelashes, wrapping the eyelashes with the concave arc surface, making the mascara at the base of the eyelashes denser. At the same time, the bristles on both sides can help separate the eyelashes, creating a "clearly defined" and dense makeup effect.

[0084] Optionally, refer to Figure 5 and Figure 6 The second bristles 130 form a first contour line 150 at one end away from the second sidewall 112. The first contour line 150 is configured as an arc segment that is concave toward the centerline of the brush rod 110. The curvature of the first outer contour formed by the second bristles 130 better fits the curve of the eye. The second bristles 130 at the end of the brush head 100 are longer than the second bristles 130 in the middle of the brush head 100. The second bristles 130 at the end of the brush head 100 can be used to brush eyelashes at the beginning and end of the eyes, thereby making the overall makeup look more refined and three-dimensional.

[0085] Optionally, refer to Figure 7 and Figure 8 The ends of the plurality of second bristles 130 away from the second side wall 112 form a first contour line 150 , and the first contour line 150 is configured as an arc segment convex toward a center line away from the brush rod 110 .

[0086] The middle portions of the multiple second bristles 130 form an outwardly convex structure, which reduces the chance of the second bristles 130 rubbing against the eyelids when applying mascara. Furthermore, the depth between adjacent second bristles 130 corresponding to the convex first contour line 150 is greater, allowing for more mascara to be carried and improved combing properties, resulting in thicker, longer, and curled lashes. Furthermore, the second bristles 130 remove excess mascara from the lashes during combing, thereby reducing clumping. Furthermore, the second bristles 130 corresponding to the convex portion can be used to partially lengthen and thicken lashes, creating different makeup styles.

[0087] Optionally, refer to Figures 1 to 8 The first side wall 111 and the second side wall 112 are disposed on opposite sides of the brush rod 110 along a first direction perpendicular to the longitudinal direction A of the brush rod 110. The first side wall 111 and the second side wall 112 are spatially independent of each other. During use, the plurality of first bristles 120 and the plurality of second bristles 130 do not interfere with each other. The user can choose to use the first bristles 120 or the second bristles 130 according to their preferences and different makeup needs.

[0088] Optionally, the brush rod 110 , the plurality of first bristles 120 and the plurality of second bristles 130 are constructed as a flat structure.

[0089] The flat first bristles 120 have a gentler slope from the middle to both sides, and the slope of uniform height is longer. When brushing the eyelashes, the longer slope can well support the ends of the eyelashes when brushing upwards, allowing the ends of the eyelashes to be better loaded with material, making the entire eyelash makeup effect longer and curlier.

[0090] Optionally, the brush rod 110, the plurality of first bristles 120, and the plurality of second bristles 130 are all made of stainless steel. Stainless steel has a smooth surface, is not easy to absorb dirt and bacteria, and is easy to clean, thereby improving eye hygiene.

[0091] Secondly, embodiments of the present application further provide a mascara brush comprising the brush head 100 described in any of the above embodiments and a brush handle 200, wherein the brush handle 200 is connected to one end of the brush rod 110 along the length direction. The brush handle 200 provides a handhold for the user to control the brush head 100 to adhere to the eyelashes, applying the brush evenly and achieving a curled, thick, and natural eyelash makeup effect.

[0092] The brush head 100 and the brush handle 200 can be integrally formed. This reduces the number of molds required, greatly simplifies the production process, improves production efficiency, and reduces costs. Furthermore, the integral formation of the brush head 100 and the brush handle 200 can reduce the gaps between the components, making the brush head 100 easier to clean and less likely to harbor dirt and reduce bacterial growth.

[0093] It should also be noted that the terms "comprises," "includes," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, commodity, or apparatus that includes a series of elements includes not only those elements but also other elements not explicitly listed, or includes elements inherent to such process, method, commodity, or apparatus. In the absence of further limitations, an element defined by the phrase "comprises a ..." does not exclude the presence of other identical elements in the process, method, commodity, or apparatus that includes the element.
