This invention relates to packages for gas mantles of the kind in which individual mantle holders are contained within an outer container. According to the invention, each holder is of the kind comprising a cylindrical sleeve member, a base and a lid and the sleeve member is non-transparent, while both the base and the lid are made from transparent, synthetic materials. The container in question has a lid that consists of a transparent, synthetic material and means are provided to ensure positive location of the individual holders in the container. The invention allows each individual gas mantle to be inspected through the transparent lid of the container to see that the mantles are intact.

Primary ExaminerLeonard Summer Attorney-Smythe & Moore ABSTRACT This invention relates to packages for gas mantles of the kind in which individual mantle holders are contained within an outer container. According to the invention, each holder is of the kind comprising a cylindrical sleeve member, a base and a lid and the sleeve member is non-transparent, while both the base and the lid are made from transparent, synthetic materials. The container in question has a lid that consists of a transparent, synthetic material and means are provided to ensure positive location of the individual holders in the container. The invention allows each individual gas mantle to be inspected through .the transparent lid of the container to see that the mantles are intact.
3 Claims, 1 Drawing Figure GAS MANTLE PACKAGES The invention relates to a package for gas mantles and includes a plurality of holders each comprising a cylindrical hollow part made from a non-transparent material, preferably cardboard, a base and a lid.
In a known package of this type, the holder base and lid are also made from a non-transparent material. This incurs the disadvantage that, when the package is sealed, it cannot be seen from outside whether the contained gas mantle is intact or not.
It is an object of the invention to establish a package for gas mantles in which each mantle can be readily seen from the outside.
In accordance with the invention, the base and the lid only are made from a transparent plastic or other synthetic material.
The holder for each gas mantle should be made transparent in order to solve the object set out above but, on the other hand, transparency should exist only in the base and lid area; in this way, the cylindrical sleeve is available for labels and illustrations.
A further development of the invention consists in that the base and/or lid have marginal areas closely abutting the cylindrical part of the sleeve which have the effect that the base and the lid can be removed by overcoming slight friction.
It is advantageous if the marginal areas are likewise transparent since, therefore, the parts of the sleeve located beneath these areas can be printed or illustrated.
Advantageously, the lid has an outwardly projecting central part, the step thereby formed being approximately one-tenth of the length of the sleeve. A pad is formed by the central part which protects the gas mantle located within the container.
The invention also relates to a container for receiving a plurality of the above-described holders, arranged closely together. According to the invention, the container lid is made from a transparent synthetic material. In this manner it is possible to examine all the gas mantles in the container for damage, without having to open the container.
Finally, it is furthermore advantageous if outwardly projecting studs are located in the lid (or base) of the container and inwardly projecting recesses are located in the base (or lid) of the container, the studs and the recesses interengaging one another when the containers are stacked one atop the other.
For equal alignment of the feet of the gas mantle, the bases of the holders may be fixed with respect to their hollow sleeve part and with respect to the tray of the container. In this way, it can quickly be seen whether the ceramic feet of the gas mantle are damaged or not.
In order that the invention may be more clearly understood, reference will now be made to the accompanying drawing, showing one embodiment thereof by way of example.
Referring to the drawing, there is shown at l a container which consists of a transparent lid 2 and an opaque or translucent tray 3. The lid 2 and the tray 3 are connected together by an adhesive strip 4 which includes a tear thread 5. Pulling on the tear thread 5 breaks the strip 4, enabling the lid 2 to be separated from the tray 3. The lid 2 has four studs 6 (only two of which are shown in the drawing and the trgy 3 has recesses 7, of which only one is s own in the rawing.
When several containers are stacked one on top of the other, the studs 6 engage the recesses 7 to support the resultant stack.
The container 1 is adapted to contain a plurality of holders 8 for gas mantles, and each of these holders consists in a cardboard sleeve 9, a transparent lid 10 and a transparent base 11. The lid and the base are preferably made of synthetic sheet material approximately 0.4 to 0.5 mm thick, and have transparent marginal areas 12 which closely abut the cardboard sleeves 9. Only the feet 13 of the ceramic socket of the gas mantle can be seen in the drawing. These are located in recesses 14 of the sleeves 9. The lid 10 has an outwardly projecting central part 15 which acts as a pad and, to a certain extent, protects the gas mantle. The central part 15 forms a step about one-tenth the length of the body member 9.
The holders 8 are orientated in the container so that one foot 13 of each gas mantle points to the left and upwardly (with respect to the drawing). This is brought about by providing the bottom of the tray 3 with ribs 16, the base 11 of each holder pack 8 with a groove 17, and the sleeve 9 of each holder with a notch 18, the ribs 16, the grooves 17 and the notches l8 interengaging in the manner shown on the drawing, preventing the holders from rotating. The ribs 16 are formed parallel to a small side of the container 1.
1. In a package for gas mantles, the combination including a first container having transparent lid means and a base means, a plurality of second containers having transparent tops, said second containers being arranged in close side-by-side relation in said first container, gas mantles in each of said second containers, said gas mantles having feet means thereon, said second containers having recesses in the upper ends thereof for receiving said feet means for holding and positioning said gas mantles in a predetermined position therein and facing said lid means, positioning means on said second containers cooperating with positioning means on the first container to position said second containers on the bottom of said first container, so that said feet means will all be held in the same relationship to the first container whereby the geometry of said gas mantles is in the same sense and can be seen from the top of the first container.
2. A package as claimed in claim 1 wherein said first and second containers have interengaging ribs and groove means.
3. A package as claimed in claim 2 wherein said first container has ribs in the bottom thereof and the second containers have groove means engageable by said ribs.
