This application Aug. 3, 1966, Ser. No. 579,443

13 Claims. (Cl. 229-15) ABSTRACT OF THE DISCLOSURE A thin wall thermoplastic container for use with a supporting holder, and the combination thereof, wherein the container and supporting holder are provided with cooperating means for releasably retaining the container within the supporting holder.

This is a continuation of Ser. No. 366,081 filed May 8, 1964, now abandoned.

The present invention relates in general to plastic articles formed from a web of thermoplastic material, and more particularly to a plastic disposable insert cup which is adapted to be inserted and retained within hollow supporting holders of varying configuration.

The present invention is an improvement over the article disclosed and claimed in my copending application entitled, Stackable Insert Container With Axially Spaced Engaging Surfaces, filed on an even date herewith, with Ser. No. 366,081, now Patent No. 3,232,512.

Conically shaped disposable insert cups made from paper products are used quite extensively in soda fountains and other similar establishments for beverage, ice cream and other food products. These cups will normally be stacked in inverted relationship on a supporting table or other convenient location, and removed one at a time from the stack. Removal of individual cups from the stack is, in most cases, accomplished by a hollow supporting holder which is inserted axially over the uppermost container for gripping a portion of the container so as to secure and support the container therewithin.

As discussed in my above mentioned copending application, pressing the supporting holder over the uppermost cup in a stack tends to create a situation where it is not always possible to freely separate individual cups. The inherent weakness of paper cups, together with the relatively rigid column of cups that is created when the supporting holder axially squeezes the cups together, decreases the possibility that single cups will be removed from the stack. The variety of supporting holders now commercially available further complicates the situation since while the supporting holders of one manufacturer may function effectively with the cups he makes, they may not always work with cups produced by a competitor.

In my copending application, I disclose and claim a novel disposable insert container or cup which limits the extent of telescopic association of like containers to enhance individual container separation from a stack, while also permitting the container to be releasably retained within a plurality of dissimilarly configured supporting holders. It has been found however that, while the stacking feature of the above disclosed container will prevent wedging between nested containers, air can be entrapped between adjacent containers, and this tends to hold the containers together when an attempt is made to remove containers one at a time from the stack. The present invention eliminates this difliculty, and at the same time preserves the stacking and holder engaging features in a disposable insert cup.

Accordingly, it is an object of the present invention to provide a disposable insert cup which is so configured that it assures air communication between nested containers to provide individual cup separation.

Another object of the present invention is the provision of a novel disposable insert cup which, in addition to promoting the introduction of air between adjacently stacked containers, prevents wedging therebetween.

A still further object of the present invention is the provision of a disposable insert cup or container, which in addition to the aforementioned objects, also promotes gripping engagement with a variety of supporting holders of dissimilar configurations.

More particularly, it is an object of the present invention to provide a novel disposable container which can be accommodated and securely retained in a releasable manner within a plurality of dissimilarly configured supporting holders, and which, when nested together with containers of like configuration, will facilitate individual cup separation.

Still another object of the present invention is the provision of a novel disposable insert container which will have maximum gripping engagement with a plurality of dissimilarly configured containers, while also affording freedom of individual cup separation.

Another object of the present invention is to provide a one piece disposable insert cup which is inherently stronger than prior disposable insert cups and not subject to attendant leakage.

Other objects and advantages will become apparent from the following description when taken in conjunction with the accompanying drawings wherein:

FIG. 1 is a front elevational view of one form of nestable insert cup constructed in accordance with the present invention;

FIG. 2 is a front elevational view of another form of nestable insert cup contemplated by the present invention;

FIG. 8 is a front elevational view, partly in section, of the FIG. 1 cup as mounted within another form of supporting holder;

FIG. 9 is a front elevational view, partly in section, of the FIG. 1 cup as mounted within still another form of supporting holder;

FIG. 10 is a front elevational view, partly in section, of the FIG. 1 :cupgas mounted within yet still another form of supporting holder;

FIG. 11 is a fragmentary front elevational view, partly in section, of the FIG. 2 cup as mounted within one still further form of supporting holder;

FIG. 12 is a front elevational view of a modified form of disposable insert cup constructed in accordance with the principles of the present invention;

FIG. 13 is a fragmentary front elevational view of still another form of disposable insert cup contemplated by the present invention;

FIG. 14 is a fragmentary front elevational view of yet still another form of disposable insert cup coming within the purview of the present invention;

FIG. 15 is a fragmentary front elevational view of one still further form of novel insert cup contemplated by the present invention; and

FIG. 16 is a sectional view of the cup shown in FIG. 15, and taken along line 1616 thereof.

In the discussion that follows, it Will become apparent that the disposable insert cup of the present invention can be associated with several forms of commercial holders now presently available. It is to be understood, however, that the disclosed forms of both the disposable insert cup and its supporting holder are to be viewed in an illustrative sense only, and are not to be taken as the only forms contemplated by the present invention.

Although any kind of material may be employed, the disposable insert cup of the present invention is preferably made of plastic, such as a high impact polystyrene. Such cups have marked advantages over paper cups which have been impregnated or coated with wax. Included among these advantages is the fact that a plastic container can be molded as a seamless thin walled unit without leakage difficulties as is well known in the art.

Referring now to the drawings, and in particular to FIG. 1, it will be seen that the form of disposable insert cup identified C1 is provided with a bottom wall it), and an upwardly and outwardly tapering side wall 12 extending therefrom to provide a container of generally frusto-conical shape. It will be observed that the side wall 12 is offset from the vertical axis of the container by an angle of approximately 20. The side wall 12 terminates at its upper margin in an open top, a radially projecting lip portion 14 being formed integral with the side wall in this vicinity. Lip portion 14 can have various shapes and configurations such as discussed in my copending application. It is to be noted that cup C1 is provided with first and second axially spaced gripping areas designated 16, 26 respectively for positive retention within hollow supporting holders of varying configuration as will subsequently appear.

The disposable insert cup shown in FIGS. 2-3 of the drawings and identified C1 is substantially similar to disposable insert cup C1 as indicated by the application of identical reference numerals with the suflix a employed to designate like parts. Cup C2 is also provided with axially spaced first and second gripping areas 16a, 26a respectively; however, in this instance, the first gripping area 16a is axially spaced upwards from the bottom wall 10a of the cup so as to provide a frusto-conical section at the lower margin of the side wall 1211. This frusto-conical section 11 provides an additional gripping area for one of the supporting holders as will become apparent.

An inspection of FIGS. 7-11 will reveal that the disposable insert cup C1 is capable of being mounted within and retained by gripping elements associated with the supporting holders designated H1-H4 whereas the cup C2, in addition to being mounted within such holders, is also capable of being received and retained within a supporting holder designated H5 in FIG. 11. This is due to the additional frusto-conical section 11 adjacent the bottom wall of cup C2.

Holders H1-H5 are illustrations of various types of supporting holders which are commercially available. The holders are generally similar in appearance, but have various gripping elements associated therewith at ditierent axial heights in the holders as dictated by the manufacturer of the same. To facilitate an understanding of the various holder configurations, a discussion will first be given relative to holder H1, and will be followed by a comparison of holders H2H5 therewith.

Holder H1 has a base 40, and a hollow container support 42. The inner peripheral wall 44 of the container support 42 has a tapered mouth area 46 which is generally all) complementary to the side wall taper of the containers C1, C2. Projecting radially inwardly from this inner peripheral wall of the container support is a gripping element 5%, which is in the form of an integral projection. As best seen in FIG. 7, this projection is adapted to cooperate with the second gripping area designated Z in cup C1.

Holders H2H5 as seen in FIGS. 8-l1 respectively, are substantially similar to the H1 holder as indicated by the application of identical reference numerals with the sutlix l, m, n, and p employed to designate like parts on holders H2, H3, H4- and H5. The holder H2, instead of having a relatively rigid abutment formed on the internal peripheral wall of the container support, is provided with an opening 48 in the internal peripheral wall 441 of the container support 42! for receiving the annular resilient grommet 52. Grommet 52 is at a lower level than the integral projection 5-0 in holder H1, and thus a portion of the first gripping area 16 has been provided for cooperation therewith to axially restrain the container within this holder.

Holders H3, H4, shown in FIGS. 9, 10 of the drawings are provided with an integral finger and ring gripping element designated 54, 5-5 respectively which is similar to the integral projection 50 in the H1 holder construction, but it should be noted that each of these gripping elements are formed at a different axial height with respect to each other and to the integral projection 50. This has necessitated the provision of additional engaging portions in the first gripping area It: for accommodating and retaining container C1 within each of the holders.

Holders iii-H4 have substantially the same axial height, but the holder H5 shown in FIG. 11 of the drawings has a slightly greater axial height. Holder H5 is also provided with an annular resilient grommet 58 which is received within an opening 48p formed in the internal peripheral wall 44p of the holder in a similar manner as the H2 holder. The grommet is designed to engage the frusto-conical section 11 projecting upwardly from the bottom wall in the C2 cup.

Where a comically-shaped paper cup of conventional character is used, each of the holders designated Hl-HS will engage different axial locations of the cup, but because of the inherent weakness of paper, there is no as surance that the cup will be positively restrained against tilting or accidental dislodgment when the cup is filled with a beverage or the like. In contrast to this, the disposable insert cup of the present invention in either of its two basic forms, will conform itself to a plurality of hollow supporting holders, and at the same time, positively engage the gripping elements of the holders.

The gripping or engaging portions on cups C1 and C2 have been previously discussed in general terms as first and second gripping areas 16, 26. Referring now more particularly to the construction of each of these gripping areas, it will be noted that the first gripping area 16 in cup C1, as best seen in FIG. 4, is provided with a plurality of engaging portions in the form of reinforcing ribs 18 which are adapted to cooperate with variously positioned gripping elements of the above discussed holders. The engaging portions decrease in diameter from the open mouth to the bottom wall as will be apparent. The bottom three engaging portions in each cup are offset from the side wall of the container by an angle of 23, and since the side wall is offset 20 from the vertical axis of the container, each of such engaging portions have a reverse taper of approximately 3 relative to the vertical axis of the container. The uppermost engaging portion in the first gripping area 16 tapers in the same maner as the side wall 12, but is offset only 15 from the vertical axis of the container to render underlying support to the side wall. The bottom three engaging portions 18 of the first gripping area each have an externally projecting shoulder 20 at its lower extremity, and an inwardly directed shoulder 22 at its upper extremity having a minimum diameter smaller than the maximum diameter of the externally projecting shoulder to facilitate stacking of containers one within the other and prevent wedging between adjacent containers by limiting the amount of axial telescopic movement.

While three reversely tapered engaging portions 18 and preferably provided adjacent the bottom wall of the container C1, it is obvious that this number may be reduced or increased as desired. It will also be apparent that only one of the reversely tapered engaging portions 18 need be used .for stacking, but in such a case, it would be necessary that this particular engaging portion have an axial height greater than that of the other engaging portions, as well as that of the circumferentially extending spaced protuberances or nubs 28 which are formed in the second gripping area 26 of the container.

The stacking of the container C2 is accomplished in the same manner as the container C1 by the formation of shoulders on the upper and lower extremity of each of the bottom three engaging portions as will be apparent by the application of the sufiix a to designate like parts in FIG. 5 of the drawings.

While the stacking feature incorporated in each of cups C1, C2 will prevent wedging between adjacent containers by limiting the amount of telescopic association therebetween, as well as spacing the side Walls of adjacent containers a predetermined distance from each other, there is a possibility that air trapped in the vicinity of the gripping areas of each of the containers will prevent withdrawal of single cups from a stack of containers. This is primarily due to the fact that a partial vacuum is formed in this area when cups are stacked in nested relationship to each other, even though they are prevented from wedging together. To obviate this difiiculty, channel means are formed in both the first and second gripping areas of the containers to assure the introduction of air therebetween, and thus enhance the separation of individual containers from a container stack. In the first gripping area 16, these channel means take the form of circumferentially spaced grooves 24 which are radially outwardly offset from the inner wall of the bottom three engaging portions 18. Preferably, there are three sets of such grooves spaced 120 apart around the circumferential periphery of the container. When the containers are nested together, these grooves will permit air to be introduced throughout substantially the entire extent of the side wall to enhance container separation. The juncture 25 between the uppermost engaging portion 18 and the side wall 12 in each container will not interfere with the similarly located engaging portion on a nested container even though this uppermost engaging portion tapers generally in the same direction as the side wall and is offset only 15 from the vertical axis of the container as compared with the angle between the side wall and the container vertical axis.

It is important to note that the channel means formed in the C1 container does not reduce to any great extent the gripping area of the engaging portions 18 since the circumferentially spaced grooves 2 are formed in the internal peripheral wall of the container, and interrupt only a small portion of each engaging portion at circumferential discrete locations. Specifically, it is to be noted that each groove 24 preferably has a width and height which is approximately one half the axial height of an engaging portion 18, and a depth at any one point less than the inwardly directed shoulder 22 of an engaging portion. While the second gripping area 26 could be formed with an engaging portion or portions similar to the first gripping area 16 construction, it has been found desirable to form an annular series of circumferentially spaced nibs or protuberances 28 which are radially outwardly deflected from the plane of the side wall so as to maintain the predetermined distance between the side walls of nested containers, and also afford passages between adjacent protuberances for the introduction of air therebetween. These protuberances are preferably hemispherical in configuration to provide a maximum cushion effect between adjacent containers, while also affording an effective engaging area with the gripping element of the H1 holder as best seen in FIG. 7.

Various types of engaging portion configurations are available for the disposable insert cup of the present invention, some examples of which are shown in FIGS. 12-16 of the drawings. In each of these views, it will be observed that there is no axially spaced first and second gripping area; however, it is to be understood that this can be provided if desired. The cup C3 shown in FIG. 12 of the drawings incorporates the circumferentially spaced protuberances which are exclusively used in the second gripping area of the preferred form of cup. It is to be noted that these circumferentially spaced protuberances are arranged in rows, the protuberances in one row being nonaligned with those of an adjacent row. In FIG. 13, the cup C4 is shown as being provided with a plurality of gripping portions decreasing in diameter from the open mouth to the bottom wall in the same manner as the preferred form of cup, and in this case, a plurality of axially extending grooves are provided which interrupt these gripping portions at circumferentially spaced locations. Cup C5 shown in FIGS. 15-16 is provided with circumferentially extending Wavy portions which incorporate the engaging and channel features of the present invention. The cup C6 shown in FIG. 14 is constructed similarly to the FIG. 12 embodiment, but instead of providing hemi-spherical protuberances, the protuberances have an elongated rectangular shape.

The preferred construction of the disposable insert cup of the present iiivention is such that the bottom wall is at least two and one half times less than the diameter of the cup at its open mouth. Although this will reduce the possibility that the cup would be able to support itself in an upright position, it will facilitate the entry within supporting holders of the above mentioned type with which the cup of the present invention is designed for use.

From the foregoing, it will now be appreciated that the disposable insert cup of the present invention will facilitate the stacking as well as the ready separation of individual containers from a stack, while also permitting the containers to be engaged and retained within a plurality of dissimilary configured supporting holders. The engaging and rim portions of each container also aid in laterally strengthening the same as will be apparent. The containers will be inherently stronger and not subject to leakage since in a preferred form they are molded in one plece from a web of thermoplastic material as is well known in the art.

Although specific embodiments have been shown and described herein, it is with full awareness that many modifications thereof are possible. The invention, is not to be restricted except insofar as is necessitated by the prior art and by the spirit of the appended claims.
