DUAL PURPOSE FOOD CONTAINER/BUILDING BLOCK ELEMENT

Description

FIELD OF THE INVENTION

[0001] The present invention relates to a dual-purpose sealable container/building block element, particularly useful as a food container. More particularly, the invention is directed to a food container which may also be used as a building block assembly toy after completing its primary use as a container. Specifically, such containers are mostly used for dairy products such as ice cream, yogurt or the like.

BACKGROUND OF THE INVENTION

[0002] Various containers arranged for connection one to another are known in the prior art of storage systems, for example as shown in US-A-3,999,818 to Schankler. The patent discloses an interlocking system of identical modules for storage of microfilm cartridges or boxes, particularly in a carousel arrangement. There is no provision for sealing the front end of the modules.

[0003] US-A-4,592,601 to Hlinsky et al. discloses an expandable modular storage system for holding slides and cassettes, using screws for interlocking adjacent elements. Modular storage units for useful as furniture items are disclosed in US-A-4,717,214 to Moore et al. The modular units are each formed from identical hingedly connected rectangular panels.

[0004] An interlocking modular display rack system is disclosed in US-A-4,480,745 to Loge et al., featuring a set of open, non-sealable holders for supporting article caddies.

[0005] US-A-4,423,913 to Lee discloses a display and storage assembly using interlocking stackable open bins, designed to be interlocked in a juxtaposed side-by-side relationship.

[0006] Other examples of stackable and interlocking containers or boxes are disclosed in US-A-3,514,170 to Shewchuk and US-A-3,506,321 to Hampel. Neither of these designs is sealable.

[0007] US-A-3,131,829 to Masser discloses an article-carrying container, which is not sealable.

[0008] In the area of food packaging containers, it is known to use open top cup-like containers made out of plastic which are manufactured by the injection or vacuum molding process, and sealed by bonded or folded aluminum foil or by elastic-type plastic covers. These containers are especially useful for such applications as dairy products which usually have short shelf lives. Most containers used today are disposable, having no other use once the original contents are emptied, thus causing a litter problem.

[0009] Building block assembly toys are well known and used by children throughout the world, and are available in various shapes and sizes. Many kinds of connecting means are used, most of them of the push-pull variety, with material elasticity and friction as the joining method, exhibiting only modest holding force.

[0010] Most building blocks available are small in size, relative to the child's environment. The reason that larger building blocks are not found on the market is that the production, storage and delivery prices for such would exceed the average family's toy budget.

[0011] US-A-4,764,143 to Gat et al discloses an assembly toy for joining cylindrical objects.

[0012] Using empty containers as toys has been suggested in FR-A-2 237 469, which describes a container such as that mentioned above with a relief of a face or other shape on the bottom for shaping soft materials or cookies, but not suitable as a constructional toy.

[0013] Another invention of this type is found in Israeli Patent No. 33024, which describes a bottle with projections and recesses which can be interconnected at many relative positions with the push-pull method of connection. This patent shows good three dimensional construction ability, but the connection is too weak for larger construction.

[0014] In US-A-4 067 475 there is disclosed a dual-purpose sealable food container/building block element according to the preamble of claim 1. A method according to the preamble of claim 14 is also known from US-A- 4 067 475. In particular, US-A-4 067 475 describes a pair of food containers which can be connected with their upper edges opposite one another and engaged with the bottom of another container. It is necessary to hold two containers opposite one another and to slide the same into the bottom of yet a third container. The connections are only for top-bottom construction and do not allow for side-to-side or side-to-bottom construction.

[0015] Accordingly, it is a principal object of the present invention to provide an improved dual-purpose food container/building block element for use in food storage and play modes.

[0016] Another object of the present invention is to provide a food container with improved connecting features which permit it to be used as a building block assembly toy after the contents are emptied.

[0017] It is another object of the invention to provide building blocks suitable for building large structures, thereby reducing the expenses of buying special assembly toys as well as reducing the litter problem posed by disposable containers.

[0018] It is still another object of the present invention to provide a food container adequate for building large, complex three-dimensional structures in the play mode, using only empty containers.

[0019] To achieve this, the dual-purpose sealable food container/building block element of the invention is characterized by the features claimed in the characterizing part of claim 1 and the method of the invention is characterized by the features of the characterizing part of claim 14.

[0020] While reference is made throughout the specification to "food containers," it is understood that the invention is not limited to such containers, and can be exploited in connection with any other uses made of the container prior to its exploitation as a building block, since its actual contents prior to such use are not an aspect of the invention. Thus, for example, empty containers which have never contained food, e.g. excess production leftovers, can also be used for purposes of the invention. Since, however, in most cases, the building block is conveniently available after prior use as a food container, reference to "food container" is made for the sake of brevity.

[0021] The container can be of any shape, for example, substantially tubular in shape, or substantially parallelepipedal in shape.

[0022] After the element has served its purpose as a food container, part of the rim can be removed by tearing it at a weak point formed during production. Thus, the lip surrounding the top open face is used for sealing purposes, by aluminum foil, flexible plastic cover, or by any other method, when in use as a food container, and the lip is used as a stopper in the play mode, alone or in combination with small projections, limiting the extent of travel of the engaged rails.

[0023] Sets comprising a combination of a plurality of elements according to the invention, wherein each two or more elements are connected to one another by the connecting rails and sockets, also forms a part of the present invention.

[0024] In another embodiment, a particularly convenient dual-purpose sealable food container/building block element, is provided with connecting rails and sockets which are asymmetric in shape.

[0025] By assembling a plurality of food containers in the play mode, three-dimensional structures may be created. In order to enable such large constructions to be firm and steady, the connecting means are of the slide type, engageable by insertion of rails at the open ends of sockets and sliding longitudinally into each other, perpendicular to the forces acting on assembled building blocks. This type of connection does not depend on friction as the main holding force, and is not easily separated.

[0026] To achieve the most versatile construction ability, the design features two connecting rails provided on opposite side walls directly opposite one another, and the connecting rail on the bottom is rotated ninety degrees about center with respect to the wall rails.

[0027] A further improvement in stability is achieved if all connecting means are each composed of two or more equally distanced rail or socket pairs. Since the rail or socket pairs are separated, the connection is less affected by external moments acting on the assembled game blocks.

[0028] In order to make assembly possible using containers with their top faces in different directions, the arithmetic ratio between height and width is kept, so that the total height of two side-to-side assembled containers, engaged to the stop position defined by the lip, measured from the bottom of one to the bottom of the other, is the same as the total width of a single container measured at both sides.

[0029] In yet another embodiment, improved rigidity of an individual container and of an assembly is achieved due to the fact that the lip surrounding the top open face is connected to the wall connecting means, and the wall connecting means are connected to the bottom connecting means directly or by internal or external ribs which do not obstruct the open ends of the connecting means. The addition of connecting means does not add significant weight to the thin-walled food container, yet the container strength is greatly increased.

[0030] Since the prevention is ultimately directed to use as a children's toy, it is important that the elements according to the invention be attractive to children. Advantages of the invention, therefore, consist in achieving a fascinating, colorful game as a by-product of packaging, with the benefits of relatively large size, at virtually no cost.

[0031] Yet another advantage of the invention is that only one type of container is sufficient for building any size and shape in all directions in the play mode, eliminating the need for manufacturing other special elements, e.g., connecting elements, not required for packaging.

[0032] Further advantages include solutions to the litter problem caused by the disposal of empty containers, and the possibility of using the connecting rails as an attachment point for an automatic filling machine, or when shipping.

[0033] Creating complex structures requires planning and use of imagination, which contribute to the development of the child, and his or her enrichment in the field of space geometry. This kind of play can engage children of a wide range of ages, according to the individual child's abilities and disposition.

[0034] Other features and advantages of the invention will become apparent from the following drawings and description.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0036] A food container constructed in accordance with the invention is shown in Figs. 1-9. The container is typically made of plastic, and is manufactured by the injection molding process from one part or a few bonded pieces (Figs. 8, 9), shaped as a rounded-edge cube truncated just below the top rounded edges, to provide an open top face, surrounded by a lip 18 outwardly protruding at the top. Lip 18 can be of any desired shape to support the preferred type of sealing.

[0037] Two pairs 1 and 2 of connecting rails and sockets, each composed of individual rails 5 and sockets 6, respectively, protrude outwardly from each of the four side surfaces. Bottom connecting rail and socket pairs 9 and 10 (Figs. 3-4), comprising individual rails 5 and sockets 6, respectively, protrude outwardly from the bottom surface.

[0038] The walls preferably taper outwardly from the bottom and are provided with wedges 21 tapering inwardly from the top to keep the rails horizontal. Side rail and socket pairs 1 and 2 are attached directly to lip 18 so that the top of the rails 5 and sockets 6 is covered. The lower end of rail and socket pairs 1 and 2 are connected to bottom rails 5 and sockets 6 at the bottom surfaces by wedges 21 followed by external ribs 19, which are low enough so as not to obstruct the lower end of the rails 5 and sockets 6. The container framework including the top lip 18, the side rail and socket pairs 1 and 2, stiffening ribs 19 and bottom rail and socket pairs 9 and 10, provides the container with the required strength.

[0039] As shown in Fig. 6, rails 5 comprise a strip 11 protruding from the surface, with a cylinder 12 integrally formed thereon, and sockets 6 comprise two strips 13 and 14, protruding from the surface each with a respective cylinder 15 and 16 integrally formed thereon. The distance between strips 13 and 14 and cylinders 15 and 16 in sockets 6 is such that rails 5 will interlock therein by a sliding movement with light pressure. Contact is made with the rail cylinder 12 at three points on its circumference, one point directly contacting the other container wall between the two strips 13, 14 of the socket 6 in which it is engaged, with the other two points being on the cylinders 15, 16 of the socket 6, while pushing those cylinders slightly outwards.

[0040] Strips 13 and 14 of the socket 6 are not centered with the cylinders 15 and 16. The distance between the centers of the strips is greater than the distance between the centers of the cylinders, to allow room for rail cylinder 12. The socket strips 13 and 14 are also thicker than the rail strip 11 because of the bending force acting while in engagement.

[0041] The connecting rails are arranged in such a manner that on two opposing walls there are rail pairs 1, each comprising two rails 5 with a fixed gap 22 (see Fig. 5) separating them, and on the other two opposing walls there are socket pairs 2, each comprising sockets 6 with the same gap 22 separating them. On the bottom surface there are provided rail pair 9 and socket pair 10, each comprising individual rails 5 and sockets 6 with the same fixed gap 22 separating them.

[0042] The bottom surface rails and sockets are perpendicular to each other, symmetrically arranged around the bottom center, and set at an angle of 90 degrees with respect to the wall rails and sockets of the same type, in such a manner that bottom rail pair 9 between side wall rail pair 1 and bottom socket pair 10 between side wall socket pair 2 appearing in the same direction are of the opposite type. Bottom rail pair 9 is shorter in length than gap 22 and bottom socket pair 10 is shorter in length than gap 22, to avoid obstruction of rail ends at the corners formed between them.

[0043] The food containers may be assembled together (see Fig. 7) by engaging the rails of one container with the sockets of another and pushing the containers in parallel and in opposite directions until the displacement along the rails 5 is stopped by top lip 18, at contact point 24 (Fig. 11). When assembling the containers with surfaces side-to-side, one of the containers must be turned upside down so the openings of the rails and sockets are facing each other. When assembling side to bottom surfaces, they can be assembled in both directions because the bottom rails are open at both ends. Bottom surfaces do not engage one another.

[0044] Furthermore, small projections 20 are provided at the bottom of lip 18, between the two rails 5 of rail pair 1 at both sides of the container, and these projections 20 are needed only when assembling bottom socket pair 10 to side rail pair 1, to serve as a stop in the particular case in which there is no other contact between lip 18 and the bottom socket pair 9 at the exact stop position.

[0045] When assembling two containers with side-to-side surfaces to the stop position (see Fig. 11), the total height 23, measured from the bottom of one container to the bottom of the other, will be the same as the total width 23 of one container measured at either of the two sides. This important fact makes it possible to connect each of the two side surfaces of a container, respectively, one side to a side surface of one container and one side to a bottom surface of another container, which are already installed in a group of assembled containers.

[0046] The order of constructing the cubic assembly of Fig. 7 is the order of the letters marked on the containers. First a surface is created by assembling A-I containers side-to-side surfaces, them J-M containers are added and are connected side to bottom surfaces alternately to the existing surface and side-to-side surfaces between them, excluding the corner in which containers K-L are connected bottom to side surfaces. It can be continued, connecting containers in all directions and even creating spaces big enough for a child to enter.

[0047] It should be noted that the L container, for example, is engaged simultaneously with containers A, K directed from above container C outwardly. This is possible since the radius of the bottom edges enables the bottoms of A and K containers to extend over the lip of C and J containers when fully engaged.

[0048] In the exploded view of Fig. 8, a five-piece container is illustrated, and the container is shown bonded as a completed unit in Fig. 9. The top part is identical to the above embodiment, but the bottom surface has four recesses 27 to accept the separated bottom rails and sockets 25 and 26, and to position them in the exact location for bonding. In the same manner, the side wall rails and sockets could be bonded. In this embodiment, stiffening ribs 29 are internal, leaving the bottom surface free for the bonding recesses 27.

[0049] Fig. 12 shows a set of two complementary containers, one comprising only rails, and the other, only sockets. Assembly is possible only when using both types of containers alternately. In the same way, it is possible to manufacture in each container one rail and one socket and in the other container sockets and rails respectively arranged to fit into the first, or to fit rails to side walls and sockets to the bottom surfaces of one container, while reversing this arrangement at the other, or any other complementary arrangement using two or more containers.

[0050] Figure 10 illustrates another embodiment of the invention, using a round-shaped container. Here, there are two pairs of rails 30 and two sockets 31 in equal division on the circumference and two pairs of rails 34 and two sockets 35 perpendicular to each other on the bottom. The rail pairs 34 and socket 35 of the bottom surface are broken at their intersection point to enable assembling in both directions. The length of the bottom rails and sockets is the same as that of the side rails and sockets, and there is no need for the projections 20 of the above cubic embodiment.

[0051] Figs. 13 and 14 illustrate another embodiment of the invention. The important feature of this embodiment is the asymmetric shape of the side rails 38 and bottom rails 44, and the side wall sockets 37 and the bottom surface sockets 43. These rails and sockets are designed so that connection is obtained by sliding rail 38 or 44 into the sockets 37 or 43.

[0052] This is best seen in Fig. 14, in which a bottom surface socket 43 is engaged with a side wall rail 38. The socket 43 comprises two parts: a vertical strip 39, which is r-shaped, with an upper portion 42, and a horizontal strip 40. The strip 40 is provided for the purpose of avoiding a lateral displacement of the rail cylinder 41 and, therefore, can be substantially shorter than strip 39, as seen in the figure.

[0053] Rail 38, which in the cross-section of Fig. 14 is seen in the mounted position, has a protruding cylinder 41 which engages the upper portion 42 of strip 39. As will be appreciated, the skilled person will be easily able to dimension the various elements of the connecting means so as to obtain a strong connection, while maintaining ease of assembly by sliding. It will also be appreciated by the skilled person that the asymmetric design of Figs. 13-14 uses a simpler production mold.

[0054] Further seen in Fig. 13 is a removable rim or lip 46, which can be removed by pulling off at the corner provided with pulling thong 47. This is done, as explained above, once the container has been emptied of food.

[0055] As will be appreciated by a person skilled in the art, the foregoing description of the preferred embodiments provides only a sample number of possible shapes, sizes, connecting and other elements, etc., and virtually countless different containers can be provided, without exceeding the scope of the invention.

[0056] Having described the invention with regard to certain specific embodiments thereof, it is to be understood that the description is not meant as a limitation since further modifications may now suggest themselves to those skilled in the art, and it is intended to cover such modifications as fall within the scope of the appended claims.
