[0030] Some liquids (e.g., laundry detergents, fabric softeners, soft soaps, hair products, and cleaning liquids) are packaged in plastic containers (e.g., blow-molded plastic bottles) and shipped to retailers or directly to consumers. During transport or delivery, the bottles may be subjected to stress (e.g., due to drops or other impacts). Bottles distributed through e-commerce channels are particularly susceptible to adverse effects due to rough handling during their delivery journey.

[0031] Some embodiments of this disclosure provide a bottle with increased impact strength in the shoulder region, such that, for example, if the bottle experiences an impact, it is less likely to break or break in the shoulder region. Embodiments of this disclosure can, for example, help prevent the bottle neck from collapsing into the bottle body, or help prevent the bottle neck from tearing off the bottle body upon impact. Some embodiments of this disclosure can help the bottle meet requirements for packaging and product integrity. The International Council for Safe Transport (ICRT) Standard 6 challenges packaging and products to withstand the dangers commonly encountered during e-commerce processing, transportation, and delivery.

[0032] As will be described in more detail below, a bottle may include a body for containing a liquid and a neck extending from the body. Multiple ribs may be arranged around the circumference of the neck, and each of the multiple ribs may extend across the interface region of the bottle between the neck and the body (sometimes referred to as the shoulder region). The ribs may have a reinforcing or dissipating effect, making the shoulder region less prone to deformation during impact (compared to a similar bottle without ribs), thereby increasing the impact strength of the bottle's shoulder region. The ribs may also reduce the total stress around the circumference of the neck (compared to a similar bottle without ribs). These and other embodiments are discussed in more detail below with reference to the accompanying drawings.

[0033] Figure 1 and Figure 2 A bottle 10 according to some embodiments is shown. As shown, bottle 10 may include a body 100 configured to contain a liquid. The liquid may be any liquid suitable for dispensing from the bottle. In some embodiments, the liquid is a detergent (e.g., laundry detergent). In some embodiments, the liquid is a fabric softener. Other suitable liquids (e.g., cleaning products, countertop cleaners, toilet cleaners, bath cleaners, soft soaps, dish soaps, hand soaps, facial soaps, shower gels, hair products (e.g., gels), shampoos, conditioners, or lotions) may be stored in and dispensed from the body 100.

[0034] The body 100 may have any shape suitable for storing liquid therein. In the illustrated embodiment, for example, the body 100 has a complex shape, including curved sides and a gradual taper inward toward the top of the body 100. However, in other embodiments, the body 100 may have another shape (e.g., a generally cylindrical shape or a generally rectangular prism shape). In some embodiments, the body 100 includes a handle 101 coupled to and extending from the body 100. The handle 101 can be used, for example, to lift or tilt the bottle 10. In the illustrated embodiment, the handle 101 is integrally formed with the body 100. However, in other embodiments, the handle 101 may be formed separately from the body 100 and then attached to the body 100.

[0035] Body 100 may define an internal volume 102 for storing liquid. In some embodiments, the internal volume 102 may have a volume of 0.5L to 10L (e.g., 1L to 8L, or 2L to 6L). In some embodiments, the liquid is disposed in the internal volume 102.

[0036] In some embodiments, the neck 108 extends from the body 100 (e.g., upward from the body 100) and defines an opening 104 for dispensing liquid from the internal volume 102. The neck 108 and the opening 104 may be positioned near the top of the bottle 10 such that liquid stored in the internal volume 102 can be poured out from the opening 104 by tilting or inverting the bottle 10.

[0037] like Figure 1 As shown, the central axis 105 extends through the center of the neck 108. In the illustrated embodiment, the central axis 105 of the neck 108 extends vertically. In other embodiments, the neck 108 may be positioned such that the neck 108 and therefore the central axis 105 are angled relative to the vertical direction. In the illustrated embodiment, the central axis 105 of the neck 108 is aligned with the central axis 106 of the body 100. In other embodiments, the central axis 105 of the neck 108 may be offset from the central axis 106 of the body 100. For example, this configuration allows for easier emptying of liquid from the internal volume 102 through the opening 104 (relative to the bottle in which the central axes 105 and 106 are aligned) by tilting the top of the bottle 10 in a direction in which the central axis 105 of the opening 104 is offset from the central axis 106 of the body 100.

[0038] In some embodiments, the neck 108 includes a spout 150 for dispensing liquid from the internal volume 102 through an opening 104. In some embodiments, the spout 150 includes a central conduit 152 defining a pouring channel 154 that guides liquid from the internal volume 102 through the opening 104. In some embodiments, the spout 150 may be at least partially disposed within the neck 108 (i.e., within the opening 104).

[0039] refer to Figure 3 In some embodiments, a plurality of ribs 110 are arranged around the circumference 109 of the neck 108. In some embodiments, each of the plurality of ribs 110 extends across the interface region 112 (sometimes referred to as the shoulder region) between the neck 108 and the body 100. The ribs 110 may, for example, reinforce the interface region 112 between the neck 108 and the body 100 and increase the impact strength of the interface region 112.

[0040] In some embodiments, one or more ribs 110 extend across the entire interface region 112 (i.e., from the neck 108 to the body 100). In some embodiments, each of the plurality of ribs 110 extends across the entire interface region 112 (i.e., from the neck 108 to the body 100). In some embodiments, one or more ribs 110 do not extend beyond the interface region (i.e., beyond the inflection point between the interface region 112 and the body 100). In some embodiments, each of the plurality of ribs 110 does not extend beyond the interface region (i.e., beyond the inflection point between the interface region 112 and the body 100).

[0041] In some embodiments, one or more ribs 110 are linear ribs (i.e., ribs 110 extend along a straight line rather than curving). In some embodiments, each of the plurality of ribs 110 is a linear rib.

[0042] In some embodiments, one or more ribs 110 have a length 116 of 1 mm to 10 mm, such as 2 mm to 5 mm. Figure 3 As shown, the length 116 of rib 110 is measured along the direction in which rib 110 extends across interface region 112. In some embodiments, two or more ribs 110 have the same length 116. In some embodiments, each of the plurality of ribs 110 has a length 116 of 1 mm and 10 mm, such as 2 mm to 5 mm. In some embodiments, each of the plurality of ribs 110 has the same length 116 (e.g., 1 mm to 10 mm, such as 2 mm to 5 mm).

[0043] In some embodiments, one or more ribs 110 have a width 118 of 0.5 mm to 3 mm, such as 1 mm to 2 mm. Figure 3 As shown, the width 118 of rib 110 is measured at the center of rib 110 along a direction tangential to the circumference 109 of neck 108. In some embodiments, one or more ribs 110 have the same width 118. In some embodiments, each of the plurality of ribs 110 has a width 118 of 0.5 mm to 3 mm, such as 1 mm to 2 mm. In some embodiments, each of the plurality of ribs 110 has the same width 118 (e.g., 0.5 mm to 3 mm, such as 1 mm to 2 mm).

[0044] In some embodiments, the thickness 120 of one or more ribs 110 is 0.2 mm to 3 mm, for example, 0.5 mm to 1 mm. Figure 4 As shown, the thickness 120 of rib 110 is measured at its center in a direction orthogonal to length 116 and width 118. In some embodiments, one or more ribs 110 have the same thickness 120. In some embodiments, each of the plurality of ribs 110 has a thickness 120 of 0.2 mm to 3 mm, such as 0.5 mm to 1 mm. In some embodiments, each of the plurality of ribs 110 has the same thickness 120 (e.g., 0.2 mm to 3 mm, such as 0.5 mm to 1 mm).

[0045] In some implementations, the ribs 110 in the plurality of ribs are of equal size. For example, each rib 110 in the plurality of ribs may have the same length 116, width 118 and thickness 120.

[0046] In some implementations, such as Figure 4 As shown, one or more ribs 110 have a rounded top surface 122, the radius of which corresponds to the thickness 120 of the rib. In some embodiments, each of the plurality of ribs 110 has a rounded top surface 122, the radius of which corresponds to the thickness 120 of the rib.

[0047] like Figure 4 As shown, in some embodiments, the upper ends 128 of one or more ribs 110 smoothly transition into the neck 108. That is, the upper ends of one or more ribs 110 and the neck 108 together form a differentiable curve. Figure 4 As shown, in some embodiments, the lower ends 130 of one or more ribs 110 smoothly transition into the body 100. That is, the lower ends of one or more ribs 110 and the body 100 together form a differentiable curve. In some embodiments, each of the plurality of ribs 110 smoothly transitions into the neck 108. In some embodiments, each of the plurality of ribs 110 smoothly transitions into the body 100.

[0048] In some embodiments, the ribs 110 are spaced apart around the circumference 109 of the neck 108, with a separation width 119 between adjacent ribs 110 (e.g., Figure 3 As shown). Figure 3 As shown, the separation width 119 is measured from the outer edge of one rib 110 to the outer edge of the adjacent rib 110. In some embodiments, the ribs in a first pair of adjacent ribs (e.g., pair 132) are separated by a first separation width, and the ribs in a second pair of adjacent ribs (e.g., pair 134) are separated by a second separation width equal to the first separation width. In some embodiments, the ribs in the first pair of adjacent ribs are separated by a first separation width, and the ribs in the second pair of adjacent ribs are separated by a second separation width different from the first separation width. In some embodiments, the ribs 110 are equidistantly spaced around the circumference 109 of the neck 108 (i.e., the separation width between each pair of adjacent ribs is equal). In some embodiments, most of the ribs 110 are equidistantly spaced around the circumference 109 of the neck 108 (i.e., most pairs of adjacent ribs have the same separation width).

[0049] In some embodiments, the width 118 of each rib 110 of a pair of adjacent ribs is 1 to 10 times the separation width 119 between the adjacent ribs (i.e., the width of each rib is greater than the spacing between them). In some embodiments, the thickness 120 of each rib 110 of a pair of adjacent ribs is approximately equal to the separation width 119 between the adjacent ribs.

[0050] In some implementations, the ribs 110 in the plurality of ribs are spaced apart at equal intervals. For example, each pair of adjacent ribs 110 may have the same separation width 119 as each other pair of adjacent ribs 110.

[0051] In some embodiments, 30 to 80 ribs 110 are spaced apart around the circumference 109 of the neck 108. For example, in some embodiments, 50 to 80 ribs 110 are spaced apart around the circumference 109 of the neck 108. As another example, in some embodiments, 70 ribs 110 are spaced apart around the circumference 109 of the neck 108. The number of ribs can vary depending on, for example, the circumference 109 of the neck 108, the width 118 of the ribs, and / or the spacing 119 between the ribs.

[0052] like Figure 3 As shown, in some embodiments, one or more ribs 110 extend across the interface region 112 at an angle 114 relative to the vertical direction. In some embodiments, for example, one or more ribs extend across the interface region 112 at an angle of 30 to 60 degrees relative to the vertical direction (such as 40 to 55 degrees relative to the vertical direction). Figure 3 As shown, the top surface 122 is drawn at the midpoint of rib 110 (width and length) (see...). Figure 4 The angle of rib 110 relative to the vertical direction is measured by the tangent to the rib. In some embodiments, one or more ribs 110 extend across the interface region 112 at the same angle 114. In some embodiments, each of the plurality of ribs 110 extends across the interface region 112 at an angle 114 relative to the vertical direction. In some embodiments, each of the plurality of ribs 110 extends across the interface region 112 at the same angle (e.g., an angle of 30 to 60 degrees relative to the vertical direction, such as 40 to 55 degrees).

[0053] In embodiments where the central axis 105 of the neck 108 is angled relative to the vertical direction, one or more ribs 110 may extend across the interface region 112 at an angle 114 relative to the central axis 105. In some embodiments, for example, one or more ribs extend across the interface region 112 at an angle of 30 to 60 degrees relative to the central axis 105 (such as 40 to 55 degrees relative to the central axis 105). In some embodiments, one or more ribs 110 extend across the interface region 112 at the same angle 114 relative to the central axis 105. In some embodiments, each of a plurality of ribs 110 extends across the interface region 112 at an angle 114 relative to the central axis 105. In some embodiments, each of a plurality of ribs 110 extends across the interface region 112 at the same angle relative to the central axis 105 (e.g., an angle of 30 to 60 degrees relative to the central axis 105, such as 40 to 55 degrees).

[0054] In some embodiments, bottle 10 includes ribs only on interface region 112. That is, in some embodiments, bottle 10 does not include any additional ribs (e.g., on body 100).

[0055] As discussed, various configurations of the ribs 110 are conceivable. The illustrated embodiment shows one configuration of the ribs 110 to produce desired characteristics for the bottle 10. For example, in the illustrated embodiment, the bottle 10 includes ribs 110 of equal dimensions (length, width, and thickness) and spaced apart (separated by width) around the neck 108. As another example, in the illustrated embodiment, the upper end 128 of each of the plurality of ribs 110 smoothly transitions into the neck 108, and the lower end 130 of each of the plurality of ribs 110 smoothly transitions into the body 100. This configuration can, for example, provide uniform reinforcement around the neck 108.

[0056] like Figure 1 As shown, bottle 10 may include a cap 200. The cap 200 may be removably attached to neck 108 to close opening 104.

[0057] In some embodiments, the cover 200 includes an upper surface 202 and a peripheral sidewall 204 extending downward from the upper surface 202. In some embodiments, the upper surface 202 and the peripheral sidewall 204 together form a cup-shaped cover portion 206. In some embodiments, the cover 200 includes a skirt 208 that extends outward and downward from the peripheral sidewall 204 and is configured to engage a neck 108 to secure the cover 200 to the neck 108. The skirt 208 may include an outwardly extending flange 212 and a downwardly extending sidewall 214.

[0058] In some embodiments, the neck 108 includes an attachment mechanism 124, and the cover 200 (e.g., the skirt 208 of the cover 200) includes a corresponding attachment mechanism configured to engage with the attachment mechanism 124 to removably attach the cover 200 to the neck 108. The attachment mechanism 124 and the corresponding attachment mechanism of the cover 200 may be a threaded connector (e.g., Figure 1 (As shown), a friction-fit connector, a snap-fit ​​connector, or any other suitable releasable attachment mechanism. The attachment of the cover 200 to the neck 108 is not limited to the arrangement shown in the figure. For example, in some embodiments, the cover 200 may be attached to the inside of the neck 108 rather than above the neck 108.

[0059] In some embodiments, when the cap 200 is attached to the neck 108, the cap 200 closes the opening 104 to prevent liquid from flowing out of the opening 104 (e.g., before use, during transport, during transport, and during storage). In some embodiments, when the cap 200 closes the opening 104, the cap prevents liquid stored in the bottle 10 from passing through.

[0060] In some implementations, the cap 200 can be removed from the neck 108 of the bottle 10 to receive a dose of liquid from the internal volume 102 of the body 100. For example, a user can dispense (e.g., pour) the liquid stored in the internal volume 102 into the cap 200 (e.g., into the cap portion 206) by tilting or flipping the bottle 10 onto the cap portion 206.

[0061] In some embodiments, when the cover 200 is attached to the neck 108, the lower edge 210 of the skirt 208 is spaced apart from the rib 110 around the circumference of the neck 108, such as... Figure 5 As shown. The lower edge of the skirt 208 may be spaced from the rib 110 by, for example, 0.5 mm to 3 mm, or, for example, 1 mm to 2 mm. The space between the lower edge of the skirt 208 and the rib 110 may have both a vertical component and a horizontal component. The space between the lower edge of the skirt 208 and the rib 110 may, for example, reduce the chance of the cap 200 contacting the body 100 or the interface region 112 during an impact. This may further reduce the likelihood of the bottle 10 breaking at the shoulder region 112 during an impact.

[0062] Bottle 10 can be produced by various methods. For example, in some embodiments, the body 100 is blow-molded, and other parts (e.g., nozzle 150 and cap 200) are made by injection molding.

[0063] In an embodiment where the body 100 is blow-molded, additional or excessive weight can be provided at the base of the neck 108 adjacent to the interface region 112 to provide additional rigidity to the interface region 112. For example, the plastic ring 126 (in Figures 4-5 (As shown in the diagram) can be disposed on the inner surface of the neck 108 behind the rib 110. For example, this can provide additional rigidity to the rib 110 and further reinforce the interface region 112. If the bottle 10 includes, as shown in the diagram, Figure 1 and 5 The nozzle 150 shown may be tapered to accommodate the plastic ring 126. For example, the outer diameter of a portion of the nozzle 150 adjacent to the edge 502 of the opening 104 may be larger than the outer diameter of a portion of the adjacent interface region 112 of the nozzle 150, such as... Figure 5 As shown. Therefore, in the vertical position of the plastic ring 126, the inner diameter of the plastic ring 126 can be larger than the outer diameter of the bottle mouth 150, such as... Figure 5 As shown. In some embodiments, the plastic ring 126 is an artifact used in the blow molding process for producing the bottle 10, and the placement of the plastic ring 126 is controlled during the blow molding process to provide the aforementioned benefits.

[0064] The components of bottle 10 can be manufactured using various materials, such as one or more plastics (e.g., polyethylene terephthalate (PET) or high-density polyethylene (HDPE)). In some embodiments, all components of bottle 10 are made of the same material, allowing the entire container to be recycled in a single recycling stream. In some embodiments, all components of bottle 10 are made of HDPE.
