Abstract: An anti-rotational system which comprises an anti-rotational box (10) for protecting containers in the box.

Description: TITLE OF THE INVF.NTTO ANTI-ROTATIONAL SYSTEM BACKGROUND OF THE INVENTION Field of the Invention: This invention concerns a system for the storage of containers such as bottles The invention more particularly concerns the retention of the bottles within a box so that the bottles do not rotate or contact each other which would result m the abrasion of the outer surface of the bottles Such abrasions on the surface of the bottles render the bottles unusable lor reuse This application claims pπoπty of Mexican Patent Application No 980170 which is hereby incorporated by reference This application is a continuation application of parent application Seπal No 09/127,803 Discussion of the Background Previously existing systems or boxes for the storage of bottles, which are used to store the bottles or to transport the bottles from one location to another, have a number of shortcomings which result m the bottle being abraded on its outer surface Such abrasions render the bottle unusable for refilling for reuse Ideally, the boxes that hold the bottles would be capable ol retaining in a single location each of the bottles so that the bottles do not contact each other Known pπor art deuces (Apps et al., U S Patents 5.405.042 and 5,320,245, both of which are incorporated herein by reference) provide dividers which are msertable mto a box so that the bottles can be handled The pπor art discloses that different dividers can be inserted into the box so as to accommodate bottles of different sizes within one type of box Hov/ever. the boxes of the pπor art allow the bottles aπanged bv the dividers to contact each other causing abrasions on the outer surfaces Another problem encountered in the pπor art aπses \\ hen manv boxes are placed one on lop ot another The box at the bottom of the pile of boxes supports the weight of the boxes and bottles above it through its side walls. In such a case, the side walls tend to warp outward. Such warpage tends to loosen the fit of the bottles situated m the box located at the bottom of the pile of boxes, thus causing the bottles to move about and to contact one another, where such contact causes abrasions on the surface of the bottles. Therefore, the bottles become unusable for refilling due to the abrasions. Ideally, the boxes that hold the bottles would be capable of supporting the weight of many boxes filled with bottles stacked above it, so that the box located at the bottom of the pile of boxes would be capable of retaining in a single location each of the bottles so that the bottles do not contact each other. Thus, there is a need for a system, such as a box, which stores containers, such as bottles, that prevents the bottles from contacting each other duπng storage and transportation. SUMMARY OF THE. INVENTION It is an object of the invention to provide a system which stores containers that prevents the containers from contacting each other's outer surfaces. In one form of the invention the anti-rotational system takes the form of an exteπor box having at least one full-depth wall having a height at least as great as a height of the containers and having a bottom structure. Formed within the exterior box structure are located pockets which retain the containers in the box. The pockets include a substantially πgid portion and an elastic portion. The substantially rigid portion engages a maximum diameter of the container and the elastic portion engages a diameter of the container which is smaller than the maximum diameter of the container with sufficient force so as to retain the container in the box. The contaπ ers ha\ e non-uniform diameters In yet another form of the invention, the anti-rotational system takes the form of an anti-rotational box, similar to the anti-rotational box descπbed above, where containers having a uniform diameter are sεcurable w lthm the pockets formed m the exteπor box. In still yet another form of the invention, the anti-rotational system takes the form of a general structural piece, such as a shelf, having pockets wherein containers are securable In another form of the invention, the anti-rotational system includes reinforcement or thickened wall πbs connected to the full-depth walls, to the bottom structure an to portions of the structure forming the pod ets Thus, Applicant's invention is supeπor to the pπor art. Applicant's inv ention provides an anti-rotational system that prevents the inserted containers from rotating and contacting adjacent containers. Therefore, the containers can be refilled for reuse since the design on the outer surface is still identifiable. Thus, the reuse of the containers results m a cost savings and. also, results m conservation of natural resources. Such structural features distinguish Applicant's invention, structurally and functionally, over the pπor art.

Figure 5 is a top view of the anti-rotational box 10 showing pockets 28a-28h Figures 6A and 6B are partial cross-sectional v iew through pocket 28e as shown in Figure 5 Figures 6 A. and 6B show the interaction between a container 30 and pocket 28e of the anti-rotational box 10 The cross-section illustrated m Figure 6B is located approximately forty-five degrees to the cross-section of illustrated m Figure 6A Figure 6A shows the container 30 and its interaction with the longitudinal πbs 16 Furthermore, the opposing parallel pairs of longitudinal ribs 16 can exemplify either one of the first and second sets of longitudinal ribs 18, 20, as shown in Figure 6A. Figure 6B shows the container 30 and its interaction with the pairs of perpendicular ribs 22. Additionally, the opposing, parallel sets of pairs of perpendicular ribs 22 can exemplify either one of the first and second sets of pairs of perpendicular ribs 24, 26, as shown in Figure 6B. The anti-rotational box 10 is molded as a single structure. The height of the full-depth walls 12 of the anti-rotational box 10 are long enough to fully cover the height of the container 30 inserted therein. Such depth provides that multiple anti -rotational boxes 10 may be stacked on top of each other or cross stacked atop each other. The anti -rotational box is preferably made of a polymeric material. The difference in distance between the maximum diameter 32 of the container 30 and the length between the set of longitudinal ribs 18, 20 is such that when the container 30 is inserted into the anti-rotational box 10 the longitudinal ribs 18, 20 elastically press against the container 30. The difference in distance between the maximum diameter 32 of the container 30 and the length between the sets of pairs of perpendicular ribs 24, 26 is such that when the container 30 is inserted into the anti-rotational box 10 the perpendicular ribs 24, 26 press against the container 30. The container 30 is preferably made of PET The container contains two liters of fluid. However, the invention can be used with any size of container. In operation a container 30 is inserted into any one of the pockets 28a-28h. For illustrations purposes assume pocket 28d or 28e is the pocket into which the container 30 is inserted. The container has a non-uniform diameter forming a waist. The container 30 has a maximum diameter 32. a minimum diameter 34. and a transition region 36 which is located in between the maximum and minimum diameters, as shown in Figures 6 A and 6B. The maximum diameter 32 of the container 30 is first introduced past the longitudinal ribs 16. The spacing between opposing longitudinal ribs 16 of a pocket 28d or 28e are such that the maximum diameter 32 of the container 30 tends to elastically deform the longitudinal ribs 16 outward. Upon further insertion of the container 30 into the pocket 28d or 28e the longitudinal ribs 16, due to their elastic nature, tend to return towards their initial position as the longitudinal ribs 16 come into contact with the transition region 36 of the container 30 which has a diameter smaller than that of the maximum diameter 32. As the maximum diameter 32 of the container 30 proceeds past the longitudinal ribs 16 the maximum diameter 32 of the container 30 comes into contact with the pairs of perpendicular ribs 22. Opposing pairs of perpendicular ribs 24, 26 are dimensioned a distance from each other so that the maximum diameter 32 of the container 30 contacts the pairs of perpendicular ribs 22. Together, both opposing pairs of perpendicular ribs 24, 26 form a substantially rigid portion. Together, both opposing pairs of first and second longitudinal ribs 18, 20 form an elastic portion. Once the container 30 is fully inserted into the pocket 28d or 28e the pairs of perpendicular ribs 22 of the first and second sets of pairs of perpendicular ribs 24, 26, and the longitudinal ribs 16 of the first and second sets of longitudinal ribs 18, 20 are in contact with the surface of the bottle 30 at the maximum diameter 32 and at the transition region 36, respectively. The container 30 is securely supported by the anti -rotational box 10. The container 30, as secured above, does not rotate nor does it lean sufficiently so as to contact adjacent containers. Therefore, the surfaces of adjacent containers 30 do not touch and as such the adjacent surfaces of the containers 30 do not abrade each other. As such, the containers 30 may be refilled and reused. The corner pockets 28a, 28c, 28f and 28h function in a manner similar to that of pockets 28d and 28e. As shown in Figures 2-5, the corner pockets 28a, 28c. 28f and 28h each have two longitudinal ribs 16 oriented approximately ninety degrees to each other, and each comer pocket has three parallel sets of pairs of perperdicular ribs 22. Two of the three sets of pairs of perpendicular ribs 22 are oriented approximately ninety degrees to each other. The third set of the three sets of perpendicular ribs 22 being oriented approximately forty-five degrees away from being perpendicular to the other two sets of pairs of perpendicular ribs 22. As discussed above, the longitudinal ribs 16 are dimeisioned so as to elastically deform so as to enable the container to pass-by the longitudinal ribs 16 as the container is secured within the pocket and, as such, the longitudinal ribs 16 form an elastic portion. Also, as described above, the pairs of perpendicular ribs 22 are dimensioned so as to be substantially rigid and. as such, the pairs of perpendicular ribs 22 form a substantially rigid portion. The action of the longitudinal ribs 16 and the pairs of perpendicular ribs 22 is such that once the container is fully inserted into one of the corner pockets 28a, 28c. 28f or 28h the container 30 does not rotate and does not contact adjacent containers so that the containers 30 can be refilled and reused. The side pockets 28b and 28g function in a manner similar to that of pockets 28a, 28c-28f and 28h, as descnbed above. As shown m Figures 2-5, the side pockets 28b and 28g each have three longitudinal ribs 16, where two of the three longitudinal ribs 16 are oπented approximately parallel to each other and the third of the three longitudinal ribs 16 is oπented approximately perpendicular to the other two longitudinal πbs 16, and each side pocket has three parallel sets of pairs of perpendicular πbs 22, where two of the three parallel sets of pairs of perpendicular πbs 22 are onented approximately mnety degrees to each other. The third set of the three sets of perpendicular πbs 22 being onented approximately forty-five degrees away from being perpendicular to the other two sets of pairs of perpendicular πbs 22. As discussed above, the longitudinal πbs 16 are dimensioned so as to elastically deform so as to enable the container to pass-by the longitudinal πbs 16 as the container 30 is secured within the pocket and, as such, the longitudinal πbs 16 form an elastic portion. Also, as descnbed above, the pairs of perpendicular πbs 22 are dimensioned so as to be substantially πgid and. as such, the pairs of perpendicular nbs 22 form a substantially πgid portion. The action of the longitudinal πbs 16 and the pairs of perpendicular πbs 22 is such that once the container is fully inserted into one of the side pockets 28b or 28g the container 30 does not rotate and does not contact adjacent containers so that the containers 30 can be refilled and reused. Testing has determined that containers stored and transported in boxes of the pπor art, without the anti-rotational system, can be reused approximately eight times before the containers are rendered useless. However, the results of testing show that containers stored and transported in the first embodiment of the anti-rotational system can be reused approximately twenty times. Furthermore, one of ordinary skill in the art would be able to use the invention of the pocket configuration 28a-28h of the anti-rotational system in a structure, such as a shelf, to secure containers therein, while the containers are stored and/or displayed. The invention of the anti-rotational system can also be used to secure containers having a single diameter along the length of the container's body When the anti-rotational box 10. or any box of the pnor art. is located at the bottom of a stack of boxes, the anti-rotational box 10 located at the bottom of the pile of boxes supports the eight (vertical load) of the boxes above it and it supports the weight of the c ontainers, w hether the containers are filled or not filled The vertical load tends to cause the full-depth walls 12 to warp, bulge, flex, or buckle outward. The warpage causes the containers secured inside the anti-rotational box 10 to become unsecured, thus causing adjacent containers to contact one another resulting in abrasions of their surfaces. A second embodiment of the invention, which is preferably used in conjunction with the first embodiment, is displayed in Figures 7-10. Figure 7 is a perspective view of an anti- rotational box 48 which provides for the anti-rotation of containers, such as bottles, inserted therein, which provides for abrasion resistance on the surfaces of the bottles due to rubbing of the bottles against adjacent bottles, while the anti-rotational box 48 is subjected to large vertical loads transmitted through the full-depth walls 12. The vertical loads are created when many boxes are stacked one on top of another. Such stacking of the anti-rotational boxes 48 occurs in warehouses and in trucks during storage and transport of the containers. Like reference numerals designate identical or corresponding parts throughout Figures 1-10. and as such a description of previously described features is not provided. In order to prevent the above-described warpage of the full-depth walls 12 which are subject to the large vertical load that results in the abraded surfaces of the containers, multiple thickened wall ribs 50, 52, 54, 56, 58 and 60 are attached along the vertical length of the inner surface of the full-depth walls 12, as shown in Figures 7-10. Thickened wall ribs 50, 52, 54, 56. 58 and 50 reinforce the full-depth side walls 12 which adds rigidity to the overall structure of the anti-rotational box 48. Figure 8 is a partial perspective cross-sectional view taken along line 8-8 of Figure 7. Figure 8 shows the placement of two of the thickened wall ribs 50, 52 connected to the full- depth walls 12. the bottom structure 14 and to matenal that form the pockets 28a-28h. Thickened wall rib 52 has a small width near a free edge of the full-depth wall 12 and tapers to a large width where thickened wall rib 52 meets the material which forms the pockets 28a- 28h. Thickened wall rib 50 tapers in a manner similar to that of thickened wall rib 52. however, thickened wall rib 50 has a small width near an open section, such as a handle, as shown in Figure S. Figure 9 is a partial perspective view taken at an angle near the bottom of the cross- section shown in Figure 8. Shown in Figure 9 are the placement of the thickened wall ribs 50, 52. Thickenec wall rib 56 is shaped similarly to thickened wall rib 50. Thickened wall ribs 54. 58 and 60 are shaped similarly to thickened wall rib 52. Placement of the remaining thickened wall ribs 54, 56. 58 and 60 are symmetrically located about the anti -rotational box 48. Figure 10 is a top view of the anti-rotational box 48 showing the placement of the thickened wall ribs 50, 52, 54. 56, 58 and 60 around the inner surface of the full-depth walls 12. The results of testing show that containers stored and transported in a device incorporating the features of both the first and second embodiments of the anti-rotational system 48 can be reused approximately thirty times, even when a vertical load of approximately two tons is applied to the full-depth walls 12 of the anti-rotational system 48. Obviously, numerous modifications and variations of the present invention are possible in light of the above teachings. It is therefore to be understood that within the scope of the appended claims, the invention may be practiced otherwise than as specifically described herein.
