United States Patent 3,417,866 REED SWITCH FOLDER PACK Kenner Seaton Omer, 0wensboro, Ky., assignor to General Electric Company, a corporation of New York Filed Sept. 18, 1967, Ser. No. 668,506 4 Claims. (Cl. 206-65) ABSTRACT OF THE DISCLOSURE A folder pack for reed switches or similar elongated articles comprising a plurality of panels having rows of slots therein for receiving the articles. The slots in alternate panels are offset or staggered with respect to the next adjacent panel so that the articles nest together without touching each other, thereby protecting the articles fiom shock or vibration damage in a minimum volume of space.

This invention relates to packaging and more particularly pertains to a new and improved package for relatively small, fragile, elongated articles such as reed switches.

In packaging reed switches or similar elongated fragile articles it is desirable that the package be light weight and inexpensive to fabricate. Also, the package must provide means for holding the articles firmly in place and furnishing the necessary protection from shock and vibration to which the package may be subjected during storage, handling and shipping. Protection must also be provided for protrusions from such articles, e.g., in the case of reed switches means for preventing bending of the wire leads must be provided. To keep overall packaging costs at a minimum it is desirable that the package be adaptable to receive different sized articles such as reed switches of various diameters and lengths and further, that the package be of such construction as to facilitate the packing and unpacking of the articles therein. It is also desirable and expeditious that the package be adaptable for ink color code markings of the article without removing the product from the package.

Accordingly, it is the primary object of the invention to provide a new and improved package for reed switches or similar articles.

Another object of the invention is to provide a universal reed switch package of such construction as to separate and protect the reed switches and to accommodate a wide range of wire lead lengths, as well as different glass portion lengths and diameters.

Another object of the invention is to provide a package that will protect and prevent the delicate and flexible lead wires from bending. Flexing the lead wires may result in breaking the wire and/ or the glass seal. In some instances excessive bending may cause stress or strain that may change the electrical characteristics of the product. Any of these defects would make the product unacceptable for its intended purpose.

Another object of the invention is to provide a package that will simplify and facilitate the packing operation and increase the packing production rate of speed without damage to the product. Similarly, these same advantages are applicable and realized when the user unpacks the product for installation or use.

A further object of the invention is to provide a reed switch package that is adaptable to ink color coding of the reed switches without removing the items from the package.

Briefly stated, the invention relates to a package for reed switches or similar articles comprising a scored, skip-cut and die cut folder card made of chip board or other suitable material. The card may have two rows 3,417,866 Patented Dec. 24, 1968 and preferably four rows of die cut elongated slots of appropriate size to receive the glass portion of the reed switches. To the back side of the slots an adhesive tape, such as masking tape or pressure sensitive tape, is applied which leaves the adhesive side of the tape exposed under each slot, the adhesive tape normally being applied as a continuous strip behind each row of the plurality of slots. The rows of slots are staggered in position relative to each other so that when the package is folded the packed rows of reed switches will nest together without touching each other and will be held in their position within the slot by the exposed adhesive side of the applied tape.

Further objects and advantages of the invention will be understood from the following complete description and the drawing wherein FIG. 1 is a perspective view of the folder pack containing a plurality of reed switches;

FIG. 2 is a cross-sectional view thereof; and

FIG. 3 is a plan view of the folder pack blank.

As illustrated in FIG. 1, the folder pack in accordance with the invention comprises a plurality of

panels

11, 12, 13 and 14 folded upon each other in accordion fashion and enclosing a plurality of reed switches 15. The reed switches 15 include an envelope 16 containing a pair of reeds 17 therein and a pair of protruding lead wires I18 extending outwardly from the ends of the envelope 16 (FIG. 2).

As shown in greater detail in FIG. 3, the folder pack comprises a first panel 11, a second panel 12 adjacent thereto, a third panel 13, and a fourth or end panel 14. The first panel 11, has a row of article receiving slots 20 which are of proper width and length to receive the langest reed switch desired to be inserted in the folder pack and panels 12, '13 and 14 have similar rows of

slots

21, 22, and 23 respectively. The rows of

slots

20, 21, 22 and 23 are centered in their [respective panels so as to provide space for accommodating lead wires 18. As indicated in FIG. 3, the longitudinal center line of the

slots

20 and 22 are in alignment with each other and staggered with respect to the center lines of

slots

21 and 23, the latter slots, 21 and 23, also being in alignment with each other. Thus, when the folder pack panels are assembled together as indicated in FIGS. 1 and 2, the articles are staggered with respect to each other and held spaced apart.

The first panel 11 and fourth panel 14 are of greater height than second and third panels 12 and .13 and are provided with means to secure the folder pack together in the folded accordion relation. Toward this end the first panel 11 is provided in the upper end thereof with a pair of elongated

tab receiving slots

24 and 25. Co-acting with the

tab receiving slots

24 and 25 are a pair of

tabs

26 and 27 provided in the outer edge of the fourth panel 14 of the folder pack. It will be noted that no fold line is provided intermediate the row of slots 20 or the row of slots 23 and the

tab receiving slots

24, 25 or the tabs 26," 27. Thus, upon the loaded folder pack being folded together as indicated in FIG. 2, the tab and slot arrangement provide a natural curvature to the packaging material to permit room for the enclosed articles.

In cutting the blank of FIG. 1 from a suitable type of material such as chip board, cut-

score lines

28 and 29 are provided between first panel 11 and second panel 12 and third panel 13 and fourth panel 14 respectively. To permit the cutting of all score lines in a single operation without requiring reversing of the blanks, a skip-cut line 30 is provided intermediate second panel 12 and third panel 13. Adhesive strips 19 of suitable length and width are provided over the rows of

slots

20, 21, 22 and 23 to complete the package for loading.

The folder pack can thus be loaded (from the rear side as shown in FIG. 3) either automatically or by hand with the reed switches or other similar articles. Each of the panels are of sufficient height to accommodate the lead length extending from either end of the reed switches so that the leads are easily maintained in a flat unbent position without risk of distortion. The exposed adhesive layer within the slots grips the glass envelope securing the same in position sufiicently so that the reed switches are held out of contact with each other. If desired, ink color coding can be easily accomplished after the pack has been completely filled while it is still in a fiat form by use of a roller coder or similar marking tool. In the flat position it is quite simple to roll a coder over the exposed glass surface of the reed switches since the circumference of the envelope of the reed switch is greater than the thickness of the chip board material. In this same manner, other operations may be accomplished if desired.

In the preferred embodiment of the folder pack, each row of slots will have 25 apertures therein so that a total of 100 reed switches may be contained in the folder pack. The slots will be 16%" in length and A3 wide and will thus accommodate both a miniature or intermediate size reed switch. This pack conserves approximately 400% in packing space over presently used packaging.

After loading, the first panel 11 and second panel 12 may be laid back against the third and

fourth panels

13, 14 and then the first panel .11 reverse folded adjacent the second panel 12 and the fourth panel 14 reverse folded against the third panel 13 to form the accordion shape of the folder pack. The

tabs

26 and 27 are inserted into the

tab receiving slots

24 and 25 and the packaging of the reed switches is completed. If desired, means may be provided for securing the lower part of the pack together.

While the invention has been specifically described with reference to a specific embodiment thereof, it will be ap preciated that several modifications can be made therein without departing from the spirit and scope of the invention. For example, the folder pack may, if desired, comprise only the first and fourth panels for containing smaller numbers of reed switches or a larger number of panels than the four depicted. Thus, the limitations as to total number of articles to be received in the folder pack are not to be considered as limiting the scope of the invention.
