Title: Anti-rotational system

Description:
BACKGROUND OF THE INVENTION 
     1. 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 in the abrasion of the outer surface of the bottles. Such abrasions on the surface of the bottles render the bottles unusable for reuse. 
     This application claims priority of Mexican Patent Application No. 980170 which is hereby incorporated by reference. 
     2. Discussion of the Background 
     Previously existing boxes for the storage of bottles, which are used to transport the bottles from one location to another, have a number of shortcomings which result in 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 of retaining in a single location each of the bottles so that the bottles do not contact each other. 
     Known prior art devices (Apps et al., U.S. Pat. Nos. 5,405,042 and 5,320,245, both of which are incorporated herein by reference) provide dividers which are insertable into a box so that the bottles can be handled. The prior art discloses that different dividers can be inserted into the box so as to accommodate bottles of different sizes within one type of box. However, the boxes of the prior art allow the bottles arranged by the dividers to contact each other causing abrasions on the outer surfaces. 
     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 during 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&#39;s outer surfaces. 
     In one form of the invention the anti-rotational system takes the form of an exterior box having at least one wall having a height at least as great as a height of the containers. Within the exterior box structure is located means for forming pockets which retain the containers in the box. The means for forming pockets include a first rigid portion and second elastic portion. The first rigid portion engages a maximum diameter of the container and the second 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 containers have 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 described above, where containers having a uniform diameter are securable within the pockets formed in the exterior 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. 
     Thus, Applicant&#39;s invention is superior to the prior art. Applicant&#39;s invention 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, conserving natural resources. Such structural features distinguish Applicant&#39;s invention, structurally and functionally, over the prior art.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Referring now to the drawings, wherein like reference numerals designate identical or corresponding parts throughout the several views, and more particularly to FIG. 1 thereof, an anti-rotational box 10 has been created 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. The embodiment of this invention is displayed in FIGS. 1-6. FIG. 1 is a perspective view of the anti-rotational box 10 showing the full-depth walls 12 and the bottom structure 14. 
     FIG. 2 is a partial perspective cross-sectional view taken along line 2--2 of FIG. 1. FIG. 2 shows the placement of the full-depth walls 12, the bottom structure 14, the longitudinal ribs 16, pairs of perpendicular ribs 22, and part of a pocket 28 formed by the periphery of the connection between the longitudinal ribs 16 and the pairs of perpendicular ribs 22. The pairs of perpendicular ribs 22 are substantially located between the bottom structure 14 and the longitudinal ribs 16. 
     FIG. 3 is a partial perspective cross-sectional view taken at an angle near the bottom of the cross-section shown in FIG. 2. Shown in FIG. 3 are the placement of the full-depth walls 12, the bottom structure 14, and the placement of the longitudinal ribs 16 and the pairs of perpendicular ribs 22 to form the pocket 28. As shown in FIGS. 2-5, the longitudinal ribs 16 are oriented parallel to the longitudinal plane of the bottom structure 14. Also as shown in FIGS. 2-6, opposing longitudinal ribs 16 form first sets of longitudinal ribs 18 and pairs of longitudinal ribs transverse to the first pair form a second set of longitudinal ribs 20. The pairs of perpendicular ribs 22 are used to form a first set of pairs of perpendicular ribs 24. Two more sets of pairs of perpendicular ribs 22 form second sets of perpendicular ribs 26 which are oriented substantially transverse to the first set of pairs of perpendicular ribs 24. Each pair of perpendicular ribs 22 substantially faces towards a center of a container 30 contained in the pocket 28. 
     FIG. 4 is a partial perspective cross-sectional view taken at an angle near the bottom of the cross-section shown in FIG. 2 showing the features of the invention. 
     FIG. 5 is a top view of the anti-rotational box 10 showing pockets 28. FIGS. 6A and 6B are partial cross-sectional view through a pocket 28 as shown in FIG. 5. 
     FIGS. 6A and 6B show the interaction between a container 30 and a pocket 28 of the anti-rotational box 10. The cross-section illustrated in FIG. 6B is located approximately forty-five degrees to the cross-section of illustrated in FIG. 6A. FIG. 6A shows the container 30 and its interaction with the longitudinal ribs 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 FIG. 6A. FIG. 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 FIG. 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 the pocket 28. 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 FIGS. 6A 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 28 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 28 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 28 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 containers 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. 
     Furthermore, one of ordinary skill in the art would be able to use the invention of the pocket configuration 28 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&#39;s body. 
     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.
