  The present invention relates to plastic bottles and preforms, and more particularly to plastic preforms and bottles blow molded from preforms, which are suitable for containing beverages and contain less resin. Utilizing bottles are lighter than conventional bottles.

  Plastic containers have been used for decades, replacing glass containers or metal containers for stuffing beverages. The most widely used plastic today for manufacturing beverage containers is polyethylene terephthalate (PET). A container made of PET is transparent, has a thin wall thickness, and can hold the shape of the container by withstanding the force applied to the wall of the container from the contents of the container. PET resin is also reasonably priced and easy to process. A PET bottle is usually formed by a molding method in which a plastic preform is blow-molded, and the plastic preform is formed by injection-molding a PET resin.

  The advantages of plastic wrapping are that it is lighter and less fragile when compared to glass, and that the overall cost is lower when both manufacturing and shipping are taken into account. Although plastic packaging is lighter than in the case of glass, make the plastic packaging the most lightweight, and use cost savings in both transportation and manufacturing by forming containers with less plastic There is still a great deal of interest in achieving the maximum.

  The bottling industry is moving in the direction of removing the auxiliary packing member from the case or pallet. The case of a bottle in which only a film is attached and no cardboard is provided is called “conversion to the film only” or “weight reduction” of the auxiliary packing member. Removing the support member, such as cardboard, adds more stress to the bottle, which makes the structural requirements on the bottle more severe. In certain embodiments, the bottle structure can provide one or more of the advantages of reducing bending failure and point load failure. The structural embodiments of the present disclosure can reduce stress during shipping and handling (including packaging with film only) while maintaining ease of blow molding. In certain embodiments, the bottle structure uses a smaller amount of resin to achieve the same or similar mechanical performance, resulting in a lighter product.

  Various embodiments of the bottles disclosed herein can use polyethylene terephthalate (PET) with creep and relaxation viscoelasticity. As plastics, PET and other resins are susceptible to relaxation at temperatures commonly encountered during use. This relaxation is a stress that changes over time, and this stress is softened by the influence of strain. Bending causes the strain to be significantly greater than that found in tensile loads. The strain becomes so great that the bending is relaxed and the situation becomes much more severe. Bending occurs at multiple length scales. Bending can occur on the bottle length scale or on a small length scale. An example of a bend on a bottle length scale is a bend that a human undergoes while bending the bottle with his / her hand or packing it into a case on a pallet. An example of a small bend is the bending or bending of a rib or other small feature on the bottle wall. As the load is applied at the first larger length scale, the ribs bend at a local smaller length scale. When these ribs are held in this posture and time elapses, the ribs are permanently deformed due to relaxation.

  Further, the various embodiments of the bottles disclosed herein can be under pressure. The pressure inside the bottle is generated by containing a carbonated beverage in the bottle. The pressure inside the bottle is generated by a pressing procedure or pressing operation performed during bottling and packaging. For example, the bottle can be pressurized to make it easier to keep the bottle shape. As another example, a bottle can be pressurized with a specific gas to facilitate holding a beverage contained in the bottle.

  Various embodiments of the bottles disclosed herein balance strength and stiffness while maintaining hoop strength to withstand the bending described above, for example when pressure is not used or when relaxed. With various depth ribs. A collection of flat and / or shallow depth ribs function as recessed columns within the bottle body, and these recessed columns are inclined by distributing bending and crushing forces along the wall. Resistant to elongation, crushing. An assembly of flat and / or shallow depth ribs can help keep the bottle in shape during pressurization, for example, help prevent bottle stretching during pressurization. By preventing the bottle from stretching, it becomes easier to maintain the desired bottle shape, and the bottle described in this specification can be easily packed, for example, by maintaining the bottle height substantially constant. . By preventing the bottle from stretching, the label can be easily applied to the label portion of the bottle. For example, when sticking a label on a bottle, it is easy to keep the length or height of the bottle in the label panel portion constant by preventing the bottle from stretching, thereby making it easier to prevent tearing of the label. And / or can prevent the label from being at least partially peeled from the bottle (ie, poor adhesion between the bottle and the label). Further details on the features and functions of various depth ribs are currently available in US Pat. No. 8, entitled “Plastic Container Having Sidewall Ribs with Varying Depth”. No. 556,098, US patent application Ser. No. 13 / 705,040 entitled “Plastic Container with Varying Depth Ribs” filed Dec. 4, 2012. US Pat. No. 8,556,098, “Plastic Container with Varying Depth Ribs (filed with various depth ribs), filed on Dec. 5, 2011. The provisions of US Provisional Patent Application No. 61 / 567,086, entitled “Plastic Containers”, the entire contents of each of which are incorporated herein by reference, It forms part of this disclosure.

  Balance can be achieved between flat and / or shallow and deep ribs to achieve the desired resistance to bending, tilting and stretching while retaining the rigidity of the lightweight bottle. In some embodiments, at least some of the desired qualities can be further enhanced by making the bottle bells steeper. By making the bell-shaped portion steeper, the crush resistance of the light bell-shaped portion can be enhanced. The lightweight bottle body and bell-shaped portion can leave a greater amount of resin at the thicker bottom of the bottle, thereby increasing stability. The thicker bottom can withstand the bending and crushing forces and is larger than the bottle diameter so that it can be tolerated even if the bottom is damaged during packaging, shipping and / or handling. Giving the benefits of a structure with

  Various embodiments disclosed herein have a plurality of strap ribs that extend from the bottom of the bottle to the side wall to provide rigidity, resistance to bending, tilting, stretching, and / or bending. It can function so that it becomes easier to secure while maintaining the above. The strap rib on the bottom can make it more resistant to deformation when the bottom is under pressure, making the bottom against a lightweight bottle (i.e. against the wall thickness of a flat leg bottom that also cannot withstand pressure). It is not necessary to make it too heavy. The strap bottom rib can be incorporated into the flat leg bottom. The flat leg base facilitates maintaining the thickness of the leg base. By maintaining the thickness of the bottom of the legs, it is necessary for the bottom to withstand forces including bending and point loads during packaging, shipping and / or handling, such as packaging with film only Easy to maintain bottle integrity during packaging and handling using lightweight packaging. The flat leg bottom works well with or without internal pressure due to, for example, the ability to maintain the relative leg thickness of the bottom of the lightweight bottle. When the strap rib is not provided, the bottom portion hardly has internal pressure resistance, and spreads out (it jumps out and the bottom portion easily moves). The strap ribs can make it easier to withstand the damage and deformation described herein without requiring a relatively heavy leg bottom. Since a relatively heavy leg bottom is not required, a smaller amount of material can be used for lightweight bottles. Furthermore, the bottom structure formed in a band shape allows the blow molding method to be carried out relatively easily as compared with the case of other known bottom parts having excellent pressure resistance. Therefore, the bottom portion having the strap rib disclosed in the present specification realizes an arbitrary bottle bottom portion having high material efficiency and excellent pressure resistance.

  As described in the present invention, the strength of the inner wall without the internal pressure (that is, the pressure is released by the user opening the lid of the bottle) by incorporating the strap rib into the bottom of the bottle side wall with the tandem body. And while maintaining performance (ie, resistance to bending and tilting), pressure resistance is imparted to the bottle receiving the internal pressure. The strap ribs cooperate with this column former around the bottle on the side wall forming a strap around the bottle to transmit stress along the height of the bottle.

  By providing the strap rib at the bottom, it is easy to maintain the strength and performance of the tandem recess formed in the bottle receiving the internal pressure. The strap ribs can enhance and retain these properties when the bottle is pressurized while maintaining stiffness and hoop strength without being subjected to pressure and withstand bending, tilting and / or elongation. For example, the strap ribs allow for the use of a flat leg bottom to increase the bottom strength when processing in the factory (ie when filling with beverage contents) and during pressurization It is possible to prevent the spread of the bottom portion or the jumping out. When the bottom of the bottle is widened, a so-called phenomenon that “the bottom easily moves” occurs. Preventing the spread of the bottom helps to place the bottle horizontally when placed on the surface and holding a flat leg as a contact site on the surface. Furthermore, the spread of the bottom can occur even in an unpressurized state or in a state where the bottle is pressurized at a low pressure, for example during shipping and handling or when filling at high speed. The strip-shaped bottom ribs also help to prevent the bottom from spreading when the interior is not pressurized or is pressurized at a low pressure. This specification describes preventing or preventing deformation in the presence of external pressure / internal pressure and / or external force / internal force, although some deformation of the bottle is within the scope of this disclosure. It should be understood that this can occur without departing. Some deformation of the bottle under external / internal pressure and / or external / internal force may occur, while retaining the very good structural properties of the features and functions disclosed herein.

  The various embodiments disclosed herein can be utilized for a wide range of bottle pressures. The strap bottom ribs can be up to 3 bar pressurized pressure in the bottle, including up to 2.5, up to 2, up to 1.5, up to 1, up to 0.5 bar, and up to 0.3 bar. These values can include endurance values, and include values for segment ranges and values listed above. The preform structure also serves to be able to withstand pressure and withstand much higher pressures than already specified by increasing the thickness of the strap obtained from the preform. The strip structure provides a more efficient means of withstanding the pressure in the bottle, and this means also works well in the absence of pressure.

  The various embodiments disclosed herein can be utilized for a wide range of bottle volumes. For example, the features and functions disclosed herein can be utilized for 3 ounce bottles with a maximum of a few gallons (1 gallon = about 4 liters) of bottles. As another example, the features and functions disclosed herein are from 12 ounces (0.35 liters) to 2 liters, 16 ounces (0.47 liters) to 1 liter, 18 ounces (0.53 liters) to 0.75 liters, and up to 3 liter bottles including 0.5 liters, can be used for 8 ounce bottles (0.24 liter / 0.15 liter) maximum, these values are in the range And the values listed so far.

  In addition, a novel approach that relies on general changes to the preform design that greatly improves the ability to efficiently blow lightweight bottles is disclosed herein. This design successfully incorporates features that protect the critical dimensions of the bottle and stabilize the production blow molding. These features can also use less resin while achieving appropriate mechanical properties to reduce the use of petroleum products in the industry.

  In general, the present disclosure includes a bottom, a bell-shaped portion, a sidewall between the bottom and the bell-shaped portion, a neck portion, a terminal portion that defines an opening leading to the interior of the container, and a side wall and a bell-shaped portion. An apparatus is provided for use with a container having a shoulder in between. In one embodiment, the bottom has a diameter that is greater than the diameter of the shoulder, so the bottom forms a single point of contact with other substantially similar containers in the production line or during packaging.

  FIG. 1 shows a bottom perspective view of one exemplary embodiment of a container 100 according to the present disclosure. The container 100 has a bottom 104 that extends upward to the grip 108. The grip part 108 includes a plurality of grip part ribs 112 (that is, side wall ribs). As shown in FIG. 1, the plurality of gripping portion ribs 112 usually change in the depth direction and are formed in a spiral shape or a multi-fold shape along the outer peripheral surface of the gripping portion 108. The label portion 116 is connected to the grip 108 and includes one or more label panel ribs 120 (ie, sidewall ribs). The label panel portion 116 transitions to a shoulder 124 that is connected to a bell-shaped portion 128. In the embodiment shown in FIG. 1, the bell-shaped portion 128 includes a plurality of design shape portions 132. However, in other embodiments, the bell-shaped portion 128 may include various other design shapes, or may be gentle and undecorated overall. The bell-shaped part 128 is connected to a neck part 136 connected to the terminal part 140. As shown in FIG. 1, the bell-shaped portion 128 has a diameter that gradually decreases as the bell-shaped portion 128 extends upward from the shoulder portion 124 toward the neck portion 136 and the terminal portion 140. The termination 140 may be adapted to receive a lid, such as a container cap or a bottle cap, for example, as a non-limiting example, and to contain the contents in a sealed manner in the container 100. The termination 140 typically defines an opening 144 that guides into the interior of the container 100 to contain the beverage and / or as a soft drink of any of a wide variety of carbonated soft drinks. Accommodates other contents.

  A generally vertical side wall comprising a grip 108 and a label portion 116 between the bottom 104 and the bell-shaped portion 128 and extending along a generally longitudinal axis of the container 100 defines at least a portion of the interior of the container 100. . In some embodiments, the sidewall may include a bell 128, a shoulder 124, and / or a bottom 104. The outer peripheral surface of the side wall (that is, the peripheral surface) is a flat outer peripheral surface that is substantially perpendicular to the longitudinal axis of the container 100. The end portion 140, the neck portion 136, the bell-shaped portion 128, the shoulder portion 124, the label portion 116, the grip portion 108, and the bottom portion 104 are each a corresponding outer peripheral surface (ie, a plane substantially perpendicular to the longitudinal axis of the container 100) , Peripheral surface). For example, the label portion 116 includes the outer peripheral surface of the label portion, while the grip portion 108 includes the outer peripheral surface of the grip portion, both of which are substantially perpendicular to the longitudinal axis of the container 100. It is a flat outer peripheral surface.

  In the embodiment illustrated in FIGS. 1-5, each gripping rib 112 includes a deep rib portion 148 that transitions to a middle rib portion 152. Then, the process proceeds to a shallow rib portion 156. Similarly, each label portion rib 120 includes a deep rib portion 160, which moves to the intermediate rib portion 164 and then moves to the shallow rib portion 168. The deep rib portion, the intermediate rib portion, and the shallow rib portion can be simply referred to as a deep rib, a middle rib, or a shallow rib, but these terms are gripping It should be understood that the ribs of portion 108 and label portion 116 are used to define various rib components. In the embodiment illustrated in FIGS. 1-5, the shallow rib portions 156, 168 are aligned perpendicular to the longitudinal axis of the container 100. As best shown in FIG. 3, the shallow rib portions 156, 168 align the equivalent tandem recesses 172, and the shallow rib portions 156, 168 are aligned in a generally vertical direction along the longitudinal axis of the container 100. It is formed in the place where it is aligned. Further, the deep rib portions 148 and 160 are aligned in a substantially vertical direction along the vertical axis or the longitudinal axis of the container 100. As described above, the embodiment illustrated in FIGS. 1 to 5 includes three columns of concave portions 172 and three portions where the deep rib portions 148 and 160 are aligned in a substantially vertical direction.

  In some embodiments, the label portion 116 has a first set of column recesses by preventing the shallow rib portion 168 of the label portion 116 from being vertically aligned with the shallow rib portion 156 of the grip portion 108. In addition, the grip 108 may have a second set of column recesses. In some embodiments, the container 100 may have tandem recesses only in the grip portion 108 or only in the label portion 116.

  In the embodiment shown in FIGS. 1 to 5, the three rows of columnar recesses 172 are spaced around the outer peripheral surface of the container 100 at equal intervals, and the deep rib portions 148 and 160 are opposite to the outer peripheral surface of the container. Located on the side. In the case where the three rows of column recesses 172 are spaced apart at equal intervals, the column recesses 172 are spaced approximately 120 degrees around the circumferential surface of the container 100. Any number of column recesses 172 may be incorporated into the design of the container 100 by increasing or decreasing the number of shallow ribs 156, 168 aligned generally vertically along the longitudinal axis of the container 100. it can. For example, other embodiments of the container 100 can include a plurality of tandem recesses 172 in the range of 1-10 tandem recesses.

  In some embodiments, the label portion 116 may include a different number of column recesses 172 than the gripper 108. For example, the label portion 116 can include six rows of narrow column recesses that are equally spaced, in which case the three column recesses are aligned vertically with the column recesses 172 of the grip portion 108. On the other hand, the remaining three columns of column recesses remain limited to the label portion 116. In the case where the six rows of vertical column concave portions are arranged at equal intervals around the outer peripheral surface of the label portion 116, the vertical concave portions are arranged every 60 degrees around the circumferential surface of the container 100. Further, when many column recesses are provided, it is possible to easily prevent the label portion 116 from being triangular. As will be appreciated, connecting a plurality of shallow ribs in tandem recesses will allow them to more strongly withstand bending outward in the radial direction, for at least a partial reason, This is because the shallow rib portion has a relatively shallow radial depth that can be used for bending. Therefore, when the plurality of shallow rib portions are connected so as to form a tandem recess, the internal pressure resistance can be made larger than that of the deep rib portion. In this way, by providing the shallow rib portions and / or the tandem recesses more frequently around the circumferential surface of the container 100, the container is deformed outward by the internal pressure of the contents in the container, and becomes triangular. It is easy to prevent the phenomenon that occurs.

  By aligning the shallow rib portions 156 and 168 forming the column recesses 172 in the vertical direction, the container 100 is resistant to tilting, collapsing, and / or stretching. Tilt may be achieved when a bottle, such as container 100, packs a top load force (tangential force or other force) onto the container during and / or after packing the bottle. It happens when receiving from the object. Similarly, crushing due to top loads can occur by receiving vertical compressive forces (or other forces) from bottles and / or other objects that are stacked on top. Elongation occurs when the container is pressurized. The tandem recesses 172 increase the rigidity of the container 100 by transmitting the resulting force along the side wall of the container 100 to the bottom 104. The deep rib portion 148 of the gripping portion rib 112 and the deep rib portion 160 of the label panel rib 120 each provide a hoop strength, which is equal to the hoop strength that a rib having a uniform depth can provide. can do. The number of ribs including the gripping portion ribs 112 and / or the label panel ribs 120 is not necessarily limited to these, for example, but any of the rib receiving portions of the container 100 such as the gripping portion 108 and / or the label portion 116. Can be varied in the range of 1-30 ribs every 10 centimeters. The aforementioned 10 centimeters used to measure the number of ribs contained in a portion of the container need not actually be 10 centimeters in length, but 10 centimeters is the predetermined length of the container. It should be understood that it is used by way of example to represent the relationship between a plurality of ribs provided in a portion.

  As described above, the three rows of column recesses 172 act to prevent the side wall of the container 100 from deforming outward and becoming triangular, and the shallow rib portions 156 and 168 are connected to the column recesses 172. By connecting in such a manner, it is possible to better withstand the force that the side wall of the container 100 bends radially outward. Preferably, the side wall portion between the columnar recesses 172 is bowed inward or offset toward the inside of the container 100 so that the outer peripheral surface of the side wall is inward from the substantially circular cross-sectional shape. It is offset to the deformed substantially triangular cross-sectional shape. In some embodiments, the sidewall offset may be offset by an angle of 0 to 30 degrees from the circular cross-sectional shape. The offset portion of the side wall is configured to withstand a force that causes the side wall to bow outwardly at internal pressure when the container 100 is filled with contents, particularly when filled with carbonated beverages. A pressure vessel is as described herein by causing an outward pushing force acting on the side wall of the vessel 100 with an internal pressure to act in the opposite direction resulting from the offset portion resisting the inward force. Instead of being deformed outwardly to form a triangular shape, a substantially circular cross-sectional shape is obtained. In this way, by incorporating the inner offset portion between the columnar recesses 172 around the outer peripheral surface of the container 100, it is possible to further prevent the phenomenon that the container is deformed outward and becomes triangular.

  Referring to FIG. 1, the bottom 104 includes three strap ribs 176. Each of the strap ribs 176 includes a sidewall end 180 that terminates along the sidewall of the container 100, as described herein. In addition, the bottom 104 includes six load ribs 184. As shown in FIG. 1, the two load ribs 184 are disposed between the two strap ribs 176. In some embodiments, the bottom 104 can include a plurality of load ribs 184 in the range of 1 to 5 disposed between two strap ribs 176. Each of the load ribs 184 has a side wall end 188 that terminates along the bottom 104 where it transitions from the bottom 104 to the side wall of the container 100. As shown in FIG. 1, the side wall end 188 of the load rib 184 can be provided at a lower position in the vertical direction along the longitudinal axis of the container 100 than the side wall end 180 of the strap rib 176. In some embodiments, the side wall end 188 of the load rib 184 can terminate along the side wall of the container 100 at approximately the same height as the side wall end 180 of the strap rib 176. As further shown in FIG. 1, the bottom 104 includes a plurality of legs 192 formed between the strap ribs 176 and the load ribs 184.

  The strap ribs 176 are relatively larger and deeper than the load ribs 184, as described herein. As shown in FIGS. 1-5, each of the strap ribs 176 is vertically aligned with one column recess in the column recess 172 so that the strap ribs 176 are equidistant around the circumferential surface of the container. It comes to be spaced apart. When the three strap ribs 176 are spaced apart at equal intervals, the strap ribs 176 are disposed at an angle of 120 degrees around the circumferential surface of the container 100. The load rib 184 is aligned in the vertical direction with the grip portion rib portion 112 between the column recess 172 and the column recess 172. In some embodiments, the strap ribs 176 may not be aligned vertically with the column recesses 172. In some embodiments, the strap ribs 176 may be spaced apart at unequal intervals around the circumferential surface of the container 100. In some embodiments, the bottom 104 can include more or fewer strap ribs 176 than the number of columns of the column recesses 172. In some embodiments, the strap ribs 176 can be aligned vertically with the deep rib portions 148, 160 and can terminate at the first deep rib portion 148 (first counting from the bottom 104). . In some embodiments, the strap ribs 176 may include sidewall edges 180 that terminate past the first shallow rib portion 156 and / or the first deep rib portion 148, such as second, third, and / or fourth gripping portions. Side wall ends 180 may terminate with ribs 112.

  FIG. 3 shows a rear elevation view of the container 100. As shown in FIG. 3, the side wall end 180 of the strap rib 176 is aligned with or substantially points to the approximate center of the columnar recess 172 that coincides with the center point of the shallow rib portion 156. As further shown in FIG. 3, the strap rib 176 forms a recess 196 having a very small area compared to the contact area of the leg 192 with the mounting surface. By using the small concave portion 196, it becomes easy to supply a larger amount of resin toward the leg portion 192 during the blow molding method, and when the resin at the position of the leg portion 192 becomes larger, it is normal. Further, the wear resistance and strength of the leg 192 can be increased. Accordingly, the strap rib 176 can function to realize the advantage of the flat leg bottom portion (that is, wear resistance) by ensuring the internal pressure resistance while leaving a sufficient amount of resin in the leg portion 192. To increase deformation resistance and / or stress resistance; and / or to increase the leg contact area to increase stability and to make the load distribution more uniform Thicken).

  As best seen in FIG. 7, the strap ribs 176 extend approximately from the center of the bottom 104, which coincides with the longitudinal axis of the container 100, as described herein. As can be understood by one skilled in the art, the strap ribs 176 can function as straps extending from the center of the side wall column recess 172 to the center of the bottom 104. As shown in FIG. 1, the strap ribs 176 provide a straighter and shorter path from the center of the bottom 104 to the side wall of the container 100 and do not extend to the vertical height of the legs 192. As described herein, the strap ribs 176 thus provide a bottom 104 that has a very high pressure resistance. Each of the strap ribs 176 serves as a force and stress coupling portion between the side wall including the columnar recess 172 and the central portion of the bottom portion 104.

FIG. 8 shows a cross-sectional view along the longitudinal axis of the bottom 104 of the container 100. As shown in FIG. 8, the strap ribs 176 of the bottom 104 extend from a bottom end 212 that is substantially parallel to the mounting surface of the bottom 104, and then gradually along a curved path having a first radius R _1d. It extends with a slope increasing in the positive direction. At height H _1d , the radius of the curved path of the strap rib 176 changes to a second radius R _2d with a slope that gradually increases in the positive direction before extending into the straight portion 220. At height H _2d , the straight portion 220 is connected to the sidewall end 180 as described herein. The first radius R _1d and the second radius R _{2d as} well as the corresponding positive slopes and heights H _1d and H _2d are described in “Plastic Container With Strapped Base” filed on Jan. 16, 2014. A plastic container having a bottom formed into a dimension value that fits within any of the suitable range values described in detail in US patent application Ser. No. 14 / 157,400, entitled “ The entire contents of this US patent application are incorporated herein by reference and form part of this disclosure. However, preferably, by combining the radius R _1d and the radius R _2d and acting together, the strap rib 176, and thus the bottom 104, can be given a gradually changing spherical shape. As described herein, the spherical shape of the container 100 better absorbs internal pressure. From experiments, the spherical shape of the bottom 104 shown in FIGS. 1-5 can withstand an internal pressure at least twice the internal pressure that the conventional bottom shape can withstand.

  The strap rib 176 shown in FIG. 8 does not include the transition curve portion between the first radius portion R1d and the second radius portion R2d, but also includes between the second radius portion R2d and the straight portion 220. You will see that it is not. However, in other embodiments, the transition curve having a radius other than R1d and R2d may be disposed between the curve of the strap rib 176 having the radius R1d and the curve of the strap rib 176 having the radius R2d. it can. In still other embodiments, the transition curve can be disposed between the curve of the strap rib 176 having the second radius R2d and the straight portion 220. These transition curves can have dimensional values, and from these dimensional values, it is believed that the strap ribs 176 and thus the spherical shape of the bottom 104 can be further fabricated.

  As shown in FIG. 7, the bottom 104 includes a gate 200 surrounded by a dome 204. The dome 204 has a bottom 104 that inclines deeper toward the mounting surface when the bottle is mounted on the mounting surface with respect to the mounting surface that is guided to the leg 192 of the wall of the bottom 104. The wall part is provided. The strap rib 176 includes a bottom end 208 that approximately terminates at the outer periphery of the dome 204. In some embodiments, the bottom end 208 of each strap rib 176 may be located external to the dome 204, similar to the bottom end 212 of the load rib 184. Each of the strap ribs 176 includes a rib sidewall pair 216 that connects the strap ribs 176 to various portions of the bottom 104 and the legs 192. The rib side wall 216 gradually transitions to the bottom portion 104 and the leg portion 192. By gradually moving gradually, the internal pressure resistance at the position of the rib side wall 216 and in the vicinity of the rib side wall 216 can be ensured, because the spherical shape portion of the container 100 is increased, This is because the internal pressure can be absorbed better. The strap ribs 176 can be relatively deeper in the bottom 104 than the load ribs 184 to ensure stress transmission and internal pressure resistance, as described herein.

  As noted above, each of the load ribs 184 includes a bottom end 212 that terminates at or near the dome 204. In the embodiment illustrated in FIG. 7, the bottom end 212 of the load rib 184 terminates before the bottom end 180 of the strap rib 176. Further, the load rib 184 is shallower than the strap rib 176. Thus, each load rib 184 has a relatively smaller rib side wall than the rib side wall 216 so that the transition from the load rib 184 to the bottom 104 and leg 192 is more rapid than in the rib side wall 216. Or abruptly. If the container 100 is subjected to a top load force during packaging, shipping, and / or handling, as the load rib 184 transitions more abruptly, the bend and / or tilt described herein, for example, the bottom 104 It will be appreciated that it can be tolerated by maintaining its integrity and shape. Furthermore, the steep transition of the load rib 184 results in a larger area of the bottom 104 that can be utilized for the relatively large legs 192. As described herein and as illustrated in FIG. 7, the larger leg 192 of the flat leg bottom, such as the bottom 104, increases the resin contact area with the mounting surface. It will be further understood that the wear resistance and stability of the bottom can be further increased. As further shown in FIG. 7, the rib sidewall 216 typically transitions more or less abruptly into the strap rib 176 than the transition from the rib sidewall 216 to the leg 192. By making the transition to the strap rib 176 more abruptly, higher rigidity can be imparted to the strap rib to withstand or prevent bending due to internal pressure.

  In the embodiment of FIG. 7, the bottom end 208 of the strap rib 176 terminates near the gate 200, and the bottom end 212 of the load rib 184 terminates near the outer periphery of the dome 204. By terminating the bottom end 208 of the strap rib 176 and / or the bottom end 212 of the load rib 184 substantially near the gate 200 or at the location of the gate 200, a higher resistance to withstand the internal pressures described herein. It can be understood that the spread of the bottom can be prevented, for example. Further, by terminating each bottom end of the bottom end 208 substantially in the vicinity of the gate 200 or at the position of the gate 200, strap ribs 176 that are substantially continuous from the gate 200 (or in the vicinity of the gate 200) to the side wall end 180 are formed. Can be provided. As shown in FIGS. 1 to 5, the side wall end 180 terminates at the position of the first shallow rib portion 156 and communicates with the column recess 172 in a straight line. By being continuous from the column recess 172 to the gate 200, it is possible to provide a substantially continuous belt-like portion or strap having pressure resistance that reaches the gate 200 from the top of the label portion 116. A substantially continuous pressure resistant strap can provide greater resistance to internal pressure, as described herein.
