ABSTRACT:
FIELD OF THE INVENTION
The present invention pertains to a container for retaining a plurality of microscope slides of rectangular shape having short and long sides and a predetermined thickness.
BACKGROUND OF THE INVENTION
Microscope slide containers are used for storing and indexing microscope analyzed specimens supported on a glass microscope slide. Such containers utilized for handling, transportation and storage of microscope slides include a plurality of individual microscope slide receiving compartments wherein each compartment is provided with protuberances extending upperly in each individual compartment for contacting the lower side of a microscope slide. In most cases, the slides which have a rectangular shape with long and short sides are usually placed in the compartments with the long sides extending horizontally, in other words, one of the long sides rests on the bottom wall of the compartment. In this position, it has been noted that the microscope slides can not be easily finger gripped for retrieval and inspection.
OBJECTS AND STATEMENT OF THE INVENTION
An object of the present invention to provide a container for receiving a plurality of microscopes slides of rectangular shape which avoids the above-described problem in that the slides are placed in the compartment resting on one of their short sides.
It is a further object of the present invention to provide a container for microscope slides where, in their upstanding position, the slides can be moved from a rearwardly inclined position to a frontwardly inclined position so that visual inspection of the slides can be made without requiring their retrieval from the compartments.
It is a further object of the present invention to provide a container for microscope slides wherein the spacing between the partitions which serve to hold the slides in their vertical position is such as to receive two contacting slides which can also be moved between a rearwardly inclined position and a frontwardly inclined position.
It is a further object of the present invention to provide a container for microscope slides so that the compartment tray can be removed and the slides retained in the container for storage.
The present invention is therefore achieved by providing a container for retaining a plurality of microscope slides of rectangular shape having short and long sides and a predetermined thickness which comprises:
a base having a bottom wall, front and rear walls and opposite side walls;
a tray removably received on the bottom wall of the base and contained within the front rear and side walls thereof;
the tray displaying a pair of laterally spaced longitudinally extending slide retaining compartments; each compartment including a bottom wall and opposite side walls and a series of longitudinally spaced partition means; the spaces between the partition means and the distance between the opposite side walls of the compartments are such as to receive the short sides of the microscope slides; also the spaces are such that the slides may be allowed to be manually moved reciprocally between a frontwardly inclined position and a rearwardly inclined position.
In one form of the invention, the spaces between the partition means are slightly greater than the thickness of two contacting slides so that the slides may also move between a frontwardly and rearwardly inclined position.
In another form of the invention, the width of the bottom wall of the base between the opposite side walls is slightly greater than the width of three laterally vertically standing slides so that the slides may be stored in three lateral rows in the base when the tray is removed therefrom.
Other objects and further scope of applicability of the present invention will become apparent from the detailed description given hereinafter. It should be understood, however, that this detailed description, while indicating preferred embodiments of the invention, is given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art.
