Collapsible animal container

A collapsible air-permeable animal container enclosing a volume between 8 cubic inches and 768 cubic inches in its expanded state is disclosed. In one embodiment, the container can be assembled from a plurality of nesting tubular frusta, one frustum serving as a base tube and another frustum serving as a top tube. The top tube can nest substantially inside the base tube when the container is in a collapsed configuration and the top tube can be locked into place relative to the base tube when the container is in an expanded configuration. The container may also include a base cap attached to the base tube that can be opened to add or remove an animal stored in the container and closed to prevent the container contents from escaping.

BACKGROUND OF THE DISCLOSURE

This disclosure relates to a container, and more particularly to a collapsible container suitable for the storage and dispensing of small animals such as crickets, similar-sized insects, mice, rats, lizards, etc.

Children like to catch insects and then need a place to put them. Insects, such as crickets are used as bait for fishing. One may not know that a container is needed until the time the small animals to be stored are encountered. It is convenient to have a container that requires little space when not in use and can therefore always be at hand in a purse or fishing tackle box, to be expanded to its regular size when needed. It is desired that the container be durable. It is also desirable for the container to be inexpensive so customers purchase them “on spec” in case animal storage is needed.

Desired attributes for such a collapsible container can include:(a) the empty collapsed configuration of the container occupies significantly less space than when the container is in its expanded configuration, used to store animals;(b) the process of converting from collapsed to expanded configuration is easy and intuitive for a user;(c) all components used to make the container are made of the same material and the same manufacturing process-reducing production cost and manufacturing complexity;(d) all components used to make the container can be made using a high-volume production process such as plastic injection molding;(e) the production process for the container directly creates porous openings for viewing the animals and venting without needing secondary operations to add holes;(f) the container is made of materials that have a specific gravity less that 1.0, so the container will float in water; and(g) the container is made of materials whose structural properties are unaffected by moisture.

SUMMARY OF THE INVENTION

The present invention comprises a rigid container that may include the following features:(a) the container can be constructed from concentric rigid tapered nested annuli of any cross-sectional shape including circles, squares, or other polygons;(b) the annuli can be made of an injection molded plastic or other material that can be cost-effectively mass produced;(c) the annuli can include vents that allow the occupants of the container to breathe;(d) the container can have an opening at the small end of its tapered shape that is small enough to be used to pour out animals individually or for dropping in food;(e) the individual annuli can include snaps or other retaining member that allow the container to maintain its extended volume;(f) the container may have an openable base that facilitates loading of batches of animals by pouring them from another container or for loading larger animals such as mice or lizards;(g) when the openable base is open, the container can be used as a net to go over an animal on a flat surface and trap it; and/or(h) the rigid container can be constructed without using any fabric or other flexible mesh.

In one embodiment, the container is a cricket basket having a collapsed height of approximately 3.25 inches and width and depth of approximately 4×4 inches—so as to fit into a fishing tackle box. In this embodiment, the collapsed height is somewhere in the range from 10% to 70% of the expanded height.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

In the following description, specific details are set forth in order to provide a clear and thorough understanding of the invention. The examples and figures displayed hereafter aim to illustrate the different functionalities associated with the invention, and demonstrate the extent by which the invention can be implemented.

The purpose for the present invention is to enable a person to have a simple low cost container for storing animals, such as crickets, when engaging in activities such as bug catching and fishing.

FIG. 1illustrates an embodiment of a collapsible animal container (also known as a holder or enclosure)100in its expanded state.FIG. 2illustrates this embodiment100in its collapsed state. Referring toFIG. 1andFIG. 2, the container100comprises a base cap, shown at101, a base tube, shown at102, an expansion tube, shown at103, a top tube, shown at104, and a top cap, shown at105. In this embodiment, the base tube102, expansion tube103, and top tube104have the general shape of square tubular pyramidal frustums that can nest inside one another when collapsed with the top tube104nesting inside of the expansion tube103which nests inside the base tube102. In this embodiment, the container100comprises three frustumal tubes (or frusta). In a simpler embodiment, the collapsible container could comprise only two tubes, a top tube104that nests and fits directly inside a base tube102with no need for an expansion tube. In another embodiment the there can be a plurality of expansion tubes103, each slightly smaller than the one below it to increase the ratio between the height of the container100in expanded state versus its collapsed state. It should also be noted that the frustumal tubes do not necessarily need to be square frustumal tubes. They could also be conical frustumal tubes or any of a variety of pyramidal frustumal tubes such as triangular pyramidal frustumal tubes, rectangular pyramidal frustumal tubes, pentagonal pyramidal frustumal tubes, hexagonal frustumal tubes, or any other nesting tubular shape capable of being understood by someone skilled in the art.

Also shown inFIG. 1andFIG. 2, the base cap101attaches to the base tube102and can be opened to provide a large space to facilitate the placement or removal of lizards, small mice, large insects, or a large quantity of insects at the same time into or from the container100. The top cap105attaches to the top tube104and allows animals to be poured out of the container100in small quantities. This opening in the top cap can also be used to drop food into the container. Further shown inFIG. 1andFIG. 2, the collapsed height of the container is less than 70% of the expanded height and greater than 10% of the expanded height.

The collapsible enclosure shown inFIG. 1andFIG. 2, is designed for small animals, such as insects, mice, rats, lizards and other animals of approximately this size. In its expanded state, a typical minimal overall size for the enclosure would be a length of 2 inches, a width of 2 inches and a depth of 2 inches, giving a total volume, when expanded, of 8 cubic inches. This would be sufficient for storing a small quantity of smaller animals, such as crickets. In its expanded state, a typical maximum overall size for the enclosure would be a length of 8 inches, a width of 8 inches and a height of 12 inches, giving a total volume, when expanded of 768 cubic inches. For reference, a typical cricket is between ‘/4 inch and 2 inches long and has a width and height approximately ½ that of its length. Lizards, mice, and similar small animals are larger. The container can be designed to accommodate animals up to 4 inches in length.

FIG. 3provides a top view of the embodiment of the container100previously shown inFIG. 1andFIG. 2. In this view, one can see how the top tube104nests in the expansion tube103, which nests in the base tube102. As a reference dimension, the size of the small opening at the top of the assembly is designed to allow individual cricket-sized animals to be poured from the container or for food to be dropped into the container. Given the dimensions of a typical cricket, or other small animal for which this container is intended, this means the opening in the top of the assembly has a cross sectional area of between 0.1 square inches (approximately 0.4 inches in diameter if round) and 1 square inch (approximately 1.1 square inches if round).

FIG. 4shows a prior art design of an insect container. This design, which was available through a company called Plano Molding in Plano, Ill., is not collapsible. The entire pyramidal structure is a single injection-molded plastic piece with a separate plastic top cap and plastic base.

FIG. 5illustrates a slightly different embodiment of the present invention in which the vent holes (shown at111) are tapered for manufacturing expediency. Tapered holes like this can be made using an injection mold that does not need complex actions in a direction perpendicular to the direction the mold opens. The details of how this is done are capable of being understood by anyone skilled in the art of plastic injection mold design.

FIG. 6illustrates three orthogonal views of the base tube for the container shown inFIG. 5.FIG. 7illustrates three orthogonal views of the expansion tube for the container shown inFIG. 5.FIG. 8illustrates three orthogonal views of the top tube for the container shown inFIG. 5.FIG. 9illustrates two views of the base cap for container shown inFIG. 5.FIG. 10illustrates two views of the top cap for container shown inFIG. 5.

FIG. 5,FIG. 6,FIG. 7,FIG. 8, andFIG. 9also illustrate features that have been fabricated into the base, base tube, expansion tube, and top tube to aid in the retention of these elements in their expanded configuration. In particular, these elements incorporate snaps that engage in slots in adjacent elements to provide positive engagement that prevent the enclosure from accidentally collapsing, thereby locking one element to another. InFIG. 5,FIG. 6,FIG. 7,FIG. 8, andFIG. 9the snaps are illustrated at112and the slots are illustrated at113.

In one embodiment all elements of the collapsible holder are made of thermoplastic using an injection molding process. The making of snaps and slots of this type is well understood by those skilled in the art of plastic injection molding and the fabrication of molds (also known as tooling) for plastic injection molding. It may also be desirable to make all parts of the same type and grade of thermoplastic material as this can simplify the molding process and reduce cost. The individual elements (base, base tube, expansion tube or tubes, top tube, and cap) could either be made in separate molds or could be made in molds that produce more than one of the individual elements at the same time.

In the foregoing specification, the invention has been described with reference to specific embodiments thereof. However, various modifications and changes may be made thereto without departing from the broader spirit and scope of the invention. The specification and drawings are, accordingly, to be regarded in an illustrative sense rather than a restrictive sense.
