Description

TECHNICAL FIELD The present invention relates to packages for air lamps, and more particularly to packages for lamps having a spherical glass envelope. More particularly, the present invention relates to a package of this type containing two or more lamps of this type. Various types of packaging for delicate and fragile items, such as electric lamps of the incandescent type, are well known in the art. For example, U.S. Patent No. 2.892.581 (A
matel), No. 4051.359 (Re We
Drake et al.) and No. 5,069,00B (Dug
re). This type of package may consist of a separate cardboard carton with opposing open ends into which a single spherical lamp is inserted. Each cart is then typically wrapped with a separate paper sleeve or similar member that covers the open end of the carton. Usually only two cartons (and therefore two incandescent lamps) are packed into a single package. Another example is a two-piece lamp package, which may be a folded sheet forming two lamp receiving chambers separated by a partition or similar member. Therefore, the partitions prevent the light rays from coming into physical contact with each other while the fine glass lamps are packaged.

Each two-lamp package is typically constructed for shipping by placing it in a large cardboard box with several other packages. To facilitate handling of the sealed boxes in the warehouse and during loading and unloading, several of these boxes are usually mounted on pallets and then stacked f-jl 7m together.

As a result of such stacking, the individual lamp envelopes of the lamp package within the shipping box are subject to compressive stress, which often causes sagging or caving in the walls of the tube. As a result, the glass bulb is often crushed and damaged. Breakage can also occur during normal handling of individual packages by the package consumer (eg, by being dropped).

As evidenced by the package examples cited above, prevention of the destruction of frail glass lamps contained within the package is usually achieved by providing isolation partitions along the entire package length to effectively separate the lamps. This is achieved by providing a shield and by providing some type of cushioning means (for example a partition with corrugations or elastic bending tabs). Alternatively, various other cushioning and shock absorbing means are also often employed in aircraft and are recognized as essential.

An expansive and unique technical idea is shown in the lamp package disclosed in U.S. Patent Application No. 412,754, which includes two
The glass envelopes of the individual lamps are actually held in physical contact with each other. To achieve retention under contact,
Each lamp is engaged with a pair of inwardly extending tabs that press the lamps together. Although this container has been found to be very acceptable as a means of holding a fairly slender glass lamp, it is necessary to use a container of fairly complex shape to ensure said engagement in the manner required. It is necessary to use tabs. Because of this complexity,
During the formation of the container, several additional cutting, folding, folding, etc. operations are required and the cost of the finished package is correspondingly higher.

OBJECTS AND SUMMARY OF THE INVENTION The principal object of the invention is to provide a simple, compact package for at least two spherical lamp articles during the above-mentioned and similar conditions, such as when the package is subjected to shock, vibration, compression, etc. It is desirable to provide a package in which the lamps are positioned in a separate relationship such that damage to the lamps (such as mishandling, rough handling, etc.) is substantially prevented.

A particular object of the present invention is that the final assembled package container is a one-piece folding structure that eliminates the need for additional parts such as seals, individual cartons, separation dividers, etc. We would like to provide this kind of package that has been eliminated.

Yet another particular object of the invention is to provide a lamp package that is easy to assemble with high productivity and therefore inexpensive to manufacture.

In accordance with one aspect of the invention, a container is provided having a number of side walls and a pair of opposing end portions each adapted to receive a respective electric lamp therein. A tab member fixed to and forming part of one of the side walls projects into the container when the lamps are positioned within the container and engages each lamp to separate them and prevent physical contact between them. prevent.

According to another aspect of the invention, there is provided a container having a plurality of side walls and a pair of opposing end portions, a pair of electric lamps disposed within the container, and a pair of electric lamps fixed to one of the side walls and one of the side walls. A lamp package is provided that includes a tab member forming a section and projecting into the container to engage each lamp to separate the lamps and prevent physical contact thereof.

DESCRIPTION OF THE EMBODIMENTS These and other objects and advantages of the present invention will become more apparent from the following description of illustrative embodiments, taken in conjunction with the drawings.

Referring to FIG. 1, there is shown a blank 10 in the form of a single sheet of material that will ultimately form the completed container of the present invention. The blank 10 is printed with identification symbols, abbreviations, etc. (not shown) and cut into the desired pattern as shown. A flat blank has several tJ? Bend lines are provided on the four sides IJA, B
, C and D. These fold lines (the various blank parts are folded along these lines)
is represented by a dashed line, and the blank portion to be cut is represented by a solid line.

As mentioned above, the blank 10 has four side walls A1B, C
and D to 1[! It is cut to determine the u. In addition,
When the blank 10 is folded into the substantially closed configuration illustrated in FIG. 2, it is cut to define two ends at opposite ends of the side walls. The two opposing side walls B and D are
The two side walls A, C that connect these side walls in the finished package are slightly larger. Comparing Figures 1 and 2, each end portion has a plurality of tab (or flap) members that are folded together in a predetermined manner and completed. The package is sealed to form a closure for each end in the package. In Figure 2, one end portion (vll! closest to the viewer) is tab A/ (extension of side wall), B/ (extension of large side wall B), C' (extension of side wall C). extension) and D′ (
(an extension of the large side HD). The second opposing end is defined in a similar manner to tabs A', B#, cI and D'.

Blank 10 is folded along dotted lines immediately adjacent each side fiA-D to form the configuration depicted in FIG. Then a pair of electric lamps 15 and 17
inserted into each of the opposite ends of the container. Lamps 15 and 17 are each of the incandescent type and typically include a metal screw cap 19 and a spherical glass envelope 21 extending from the cap and containing the lamp's filament structure, gas atmosphere, etc. It consists of Lamps of this type are well known in the art) and typically have a wattage rating of 40.60.75.100 or 150W. However, with respect to the present invention, it should be understood that the teachings described herein are readily applicable to lamp containers of other types than those described above. Before sealing the open end of each lamp d, it is inserted from that end in the direction shown in FIG.

In order to effectively separate the two lamps within the cardboard container so that the lamps are not in physical contact with each other but are placed very close together in the completed pancage,
A tab member 23 is employed. The tab member is cut from the side wall and has a substantially straight line PL-FL at its end.
It can be bent along. The tab members 23 are simply folded inwardly in the manner illustrated in FIG. 2 before insertion of the electric lamp 15.17. Then, the lamp is connected to the tab member 2.
It is inserted until it engages with 3. Each end tab is then folded to seal each open portion of the container. The final position of the lamp is illustrated in FIG. As shown, the tab members 25 allow each lamp to be physically connected to each other in the completed package. prevent touching. Specifically, tab member 23 is sufficiently flexible to engage the glass envelope portion of each lamp and to substantially follow most of the external contour of each envelope during this contact. This is an important feature of the invention in that it helps minimize the total interior space required to accommodate two lamps. For clarity, the side wall D on which the tab member 23 is formed
ij[[Not shown. However, the original form is represented by the imaginary lines shown.

In this manner, the completed lamp package illustrated in the third section, including the desired base paper container and a pair of electric lamps, is easy to transport and store prior to its sale. As will be apparent, while the forming operations necessary to fabricate the disclosed method are relatively simple and as described above, the tab member that effectively separates the relatively delicate contents of the container is truly unique. The simplicity ensures that the product is relatively easy and inexpensive to manufacture.

As mentioned above, the blank 10 from which the container of the present invention is formed
is formed from a single sheet of material.

Suitable materials include: faithful bleached sulfate chipboard;
Examples include bleached manila paper and machine clay-coated newsbacks. This material also preferably consists of a monolayer structure. The resulting container does not contain corrugations or similar recesses previously required in many prior art electric lamp packages. The thickness of the base paper material of the invention preferably ranges from about Q. having opposite ends of the shape.

Referring to FIG. 2, it is preferable that the tab member 23 is initially bent along 1FL-PL so that it is positioned at an angle of about 40 degrees to about 50 degrees with respect to the insertion direction of each electric lamp 15 and 17. (The insertion direction of each lamp is opposite to each other). This angle is depicted by rXJ in FIG. 2 and is approximately 45
It was °.

With particular reference to FIGS. 1 and 2, the tab member 23 includes a pair of opposing quadrants 51 and an elongated end section 33 (opposite the portion that remains fixed on side mD of the tab member). It is preferable that the external form has the following. As shown in the third FA, the elongated end section 53 forms a common engagement with each glass envelope in the completed package and separates the spherical glass envelope portions of the lamp. (2) of sufficient length and overall dimensions to ensure that the respective caps and the remainder of the envelope are maintained in the spaced apart relationship shown. Each lamp is maintained in abutment with the inner surface of the various side walls and end portions of the container in the positioning relationship described above.

To facilitate opening of the assembled package, the large end tab B' (which serves as the final cover for the end section of the container of the invention) has a centrally divided strip section 35. are doing. Customers who have purchased a package of the present invention will be provided with tab-shaped ends 3 in a direction transverse to the top of the package.
Just subtract 7 (Figure 2). Each of the remaining end tabs forming this end portion of the completed package can then be easily folded open to facilitate removal of the bulb having a glass envelope near its end. I can put it out.

Thereafter, the user of the package can easily take out the remaining lamp. At this time, it is done by simply grasping the end of the cap.

In this way, both bulbs can be removed from only one of the open ends of the completed package.

The tabs forming the remaining (non-open) ends of the packages of the present invention may be adhered using glue or similar adhesives well known in the art. This method of sealing is desirable because this end of the package cannot be opened afterward by the user of the package, as discussed above. The work of joining the remaining parts necessary to form the above-mentioned package involves abutting (internally) the protruding tab 39 (Fig. 1) extending from the large side wall and the corresponding portion (GL) of the small side wall A. The only thing that can be done is to attach it in a specific manner. End piece 39 is also shown in phantom in FIG.

There has thus been shown and described an improved lamp package for a pair of electric lamps that includes as part of a fairly delicate glass envelope. The container is constructed from a single sheet of cardboard material;
Because it is subject to relatively little cutting, bending, and folding operations, the present invention is easily adapted to mass production and is extremely inexpensive to manufacture. Additionally, the machinery required to perform the cutting, bending and folding described above is considerably less expensive than the existing machinery required to produce the relatively complex packages found in the prior art. The invention described above eliminates the need for a full length separator forming a second cardboard component that is required in many prior art packages and also forms part of the final package.

The present invention is also extremely compact compared to many prior art lamp packages. As an example, two 60
A completed package containing a W incandescent lamp will cost approximately 4.
Overall height of 575 inches, width of approximately 350 inches, approximately '1.5
It had a thickness of only 75 inches.

Although the present invention has been described above with reference to preferred embodiments, it will be obvious to those skilled in the art that various changes and modifications can be made without departing from the technical idea of the present invention.
