Abstract
ABSTRACT OF THE DISCLOSURE
A packing container for elongated objects of variable length is formed of two tubular shaped bodies each closed at one end and open at the other. One of the bodies fits into the other in a telescoping manner. In a telescoped posi-tion the inner body has a longitudinal groove extending from its open end with equidistantly spaced locking grooves opening off the longitudinally extending groove. The outer body has one or several inwardly projecting detents formed adjacent its open end. If plural detents are used, they are longitud-inally aligned and arranged at the same spacing as the locking grooves. The detents are shaped to pass through the longi-tudinally extending groove and to fit into the locking grooves.
By relative rotation of the telescoped bodies about their longitudinal axes, the detents can be moved into the locking grooves and the two bodies locked together at a selected overall length in accordance with the length of the packaged object.

Description
liUi~fjO , The present invention is directed to a packing con-tainer for elongated objects and, more specifically, it 1 concerns the arrangement of two elongated hollow bodies each closed at one end and open at the other so that the bodies can be telescoped one into the other and fixed at a variable selected length by relative rotation of the bodies about their longitudinal axes.
If elongated objects of different variàble lengths , are to be packed in a container so that they perform little 10 or no movement in the longitudinal direction, it is necess- i ary to provide a container corresponding to each of the different lengths of the objects. Such a packaging proce-dure leads-to a plurality of different sized containers each ¢
adapted to one of the differentlengths of the objects. As a result, not only does the cost of packaging increase, because ~-different molds or tools are required for producing the pack- ¦ -~
ing containers, but the cost of stock-keeping is also in-creased, since a certain supply of the containers must always l~
be available. Another factor which complicates the problem 20 of packaging elongated objects, for instance drills, chisels and the like, is the fact that such objects have larger cross sectional dimensions in accordance with the length of the object, that is, there is a certain ratio between the length and the circumferential dimensions of the object.
~ To meet the demands for a reduction in the number - of container parts of different longitudinal and cross sectio-nal dimensions which must be stocked, it has been known to utilize a container formed of two elongated pa-rts each closed at one end face and with the open ends joined together by a threaded 30 arrangement. In such a container one part of a standard size i, -1- ~ . ~ ,~
,, ,, ,: :
~ 4~
is used for objects within a certain range of dimensions, while the other part is provided in variable lengths with a cross sectional configuration corresponding to the part of standard length. As a result, it is possible to reduce the costs of producing and storing the containers, since only the length of one part needs to be varied within certain limits while the other or standard length part remains unchanged. However, this known container arrangement is still unsatisfactory, because the one part must be provided in a variety of lengths corresponding to the lengths of the objects to be packaged.
If we assume, for example, that drills having lengths of 20 to 40cm. are to be packaged and they have delicate cutting -edges which must be protected and there is only slight variation in the diameter of the drills, a container of a constant diameter can be used, however, only one part of the container can remain ;
constant in size while the other part must be provided in a ~number of graded lengths. ~ -~
.
The present invention is directed to the problem of providing a container for use in packaging elongated objects ~20 which have a wide length range, where thelsame parts can be used over the length range of the objects. Accordingly, the same two-part container can be used to package objects where the longest object is about twice the length of the shortest object.
I we assume, for example, that a drill of 35cm.
in length ~ust have a container of a corresponding length, the same x container should also be usable for drills of about twice that length, for example 60cm. in length.
In accordance with the present invention, the problem is solved by providing a two-part container consisting of a ~`
~30 fir~t part telescopicaliy displaceable into a second part so ~ -. . .

However, this known container arrangement is still unsatisfactory, because the one part must be provided in a variety of lengths corresponding to the lengths of the objects to be packaged.

The present invention is directed to the problem of providing a container for use in packaging elongated objects ~20 which have a wide length range, where thelsame parts can be used over the length range of the objects. Accordingly, the same two-part container can be used to package objects where the longest object is about twice the length of the shortest object.
I we assume, for example, that a drill of 35cm.
in length ~ust have a container of a corresponding length, the same x container should also be usable for drills of about twice that length, for example 60cm. in length.
In accordance with the present invention, the problem is solved by providing a two-part container consisting of a ~`
~30 fir~t part telescopicaliy displaceable into a second part so ~ -. . .
-2- ~;
," ' ,:
` ` 16)44~60 that the outer wall of the first part bears on the inner wall of the second part. The two parts are each closed at one end and open at the other and a groove is formed in the first part extending from its open end parallel to its longitudinal axis. I
A plurality of locking grooves extend transversely to the axis of the longitudinal groove and the locking grooves are j~
equidistantly spaced apart along the longitudinal groove. At -least one inwardly projecting detent is formed on the second part adjacent its open end and is shaped to pass through the ~10 longitudinal groove and to fit tightly into the locking grooves.
-With such a two-part container the problem of a single container for objects having a range of lengths is solved. Due to the relative displaceability of the two parts one within the other and the provi~ion of the longitudinal grooves in one with locking grooves opening from it and the detent in the other part which is displaceable through the longitudinal groove and positionable within the locking grooves, it is possible to provide a container whose length can be varied in accordance -~ with the length of the object being packaged. The range of lengths to be accommodated within the container is determined `
by the spacing between the locking groove closest to the open end of the first part and the lock$ng groove closest to the closed end of the first part. ;~ ;
Preferably, both parts of the container are cylindrical.
Further, it is preferable if the longitudinal groove extends from the open end to the closed end of the first part so that the maximum portion of its total length is usable. Accordingly, locking grooves are provided over the entire length of the longitudinal groove and are equidistantly spaced apart. A
~30 spacing of 1.5 to 2cm has been found to be particularly ;;
; ~3~ ;
. .
,~
11)4~0 advantageous for the locking grooves.
Though a single detent in the second part of the container may be sufficient, it is advantageous if several !;
detents, preferably three, are used, since the multiple detents ~i afford a better locking action and greater rigidity to the overall container, especially if the two parts are in a telescoped arrangement over only a relatively small length. Furthermore, it is preferable if the detents are circular and more particularly frusto-conical with a steep cone shell angle. ~;
The opening from the longitudinal groove into each of .the locking grooves has a width which is preferably equal to ; or slightly smaller than the diameter of the ~e~ènt, so that a certain resistance must be overcome in displacing the detents into and out of the locking grooves. Further, the opening into (.`
:~ ~ the locking grooves has a pair of opposed surfaces which pre-; fera~ly are arranged first in converging relationship from the ~:
~ longitudinal groove towards the locking groove and then in diverging relationship into the configuration of the locking groove. As j`
a result, a pair of oppositely arranged apexes are provided in 20 . the surfaces of the opening into the locking grooves. Furthenmore, ~ :
an extension can be provided from the locking grooves spaced from and extending parallel to or slightlylobliquely to : :
the axis of the longitudinal groove so that the detent~ can be introduced through the extensions after the relative rotation ~
between the two parts effects the movement into the locking ~ : :
grooves followed by a movement substantially parallel to the ¦~
longitudinal axes of the container parts about which the ~: rotation t~kes place.
~1 At its end adjacent the open end of the first part, the ~ :
~ 30 longitudinal groove can be dovetailed or it can be provided with a ~ :

movement of the detents into the longitudinal groove. I
The various features of novelty which characterize the invention are pointed out with particularity in the claims annexed to and forming a part of this disclosure. For a better `

In Fig. 1 a container embodying the present invention is illustr?ted consisting of two parts, a first part 1 and a ~-~ .
i6J 9t L~ ~ ~;0 ' ' second part 2 with the first part being movably displaceable in a telescoping manner into the second part. With the first ,, part telescoped within the second part, the outer surface of the first part bears against the inner surface of the second part.
me first part 1 is in the form of a sleeve having a longitudinally extending groove 3 of constant depth and width which extends parallel to its longitudinal axis. Extending transversely of the longitudinal groove and equidistantly ~ .
spaced along its length are locking grooves or recesses 4.
The locking grooves or recesses are similarly shaped to each other and have the same depth as the groove 3. As viewed in Fig. 1 the longitudinal groove 3 has an inlet portion 3A and '~
~; extends from the open end 5 of the first part 1 to a location `~ adjacent to but spaced from the closed end 6 o~ the part.
The length of the longitudinal groove 3, or more precisely, the length of the longitudinal groove 3 containing the locking , grooves or recesses 4 determines the variable length of the container capable of being formed by the two parts 1,2.
The second part 2 is also in the form of a sleeve 1--of somewhat larger diameter having a closed end 7 and an open end 8. Adjacent the open end 8 three detents 9 are shown projecting inwardly into the second part 2. While a single detent would -~
be sufficient to provide the locking action between the first and second parts 1 and 2, it is preferable to use three detents ~ ;
aligned in the longitudinal direction of the part 2. The detents 9 have a complementary sh~pe to the longitudinal groove 3 and they are spaced at the same intervals as the locking grooves or recess 4. Further, the detents are shaped to fit in locking engagement within the locking grooves 4. The first and second ~; 30 parts 1, 2 can be secured together in a telescopic manner to form )4~0 ,,,, "
an elongated container closed at its oppo~lte end~. In .. ~ .
securing the two parts together the detents 9 are guided within the longitudinal groove 3 until the desired overall length of the container is selected. With the desired length established, the parts 1, 2 are rotated relative to one another about their longitudinal axes so that there is a relative movement of the detents 9 in the direction of the arrow A, note Fig. 1, for securing the detents into the corresponding locking groove 4.
As illustrated in Fig. 1, the detents 9 are circular ~-10 and the locking grooves have a similar shape for receiving and ~' ho}ding the detents. As shown in Fig. 5, starting from the edge of the longitudinal groove 3, each of the locking grooves j 4 has a horse~hoe-shaped contour. The inlet openings from the longitudinal groove 3 into the locking grooves 4 is somewhat -smaller than the diameter of the detents. The dimension of the opening into-the locking grooves 4 depend~ on the material used in forming the container parts, but it is such that a certain .
resistance must be overcome in movinq the detents into and out ~ ;~
of the locking grooves. The opposite surfaces forming the opening into the locking grooves can be arranged in converging relationship from the edge of the longitudinal groove 3 to a point closely ~paced from the longitudinal edge and then the -~
surfaces can diverge again entering into the horseshse-shaped locking groove. As a result, each of the opposite faces forms ; an apex-like arrangement forming a restricted opening into the -~
locking groove 4.
As illustrated in Figure 1, the inlet end 3a of the longitudinal groove 3 at the open end 5 of the first part 1 has a, tapered chamfer surface 10 on one side while the opposite side is rectilinear in aligmnent with the remainder of that '5, . .. .

edge of the longitudinal groove. As an alternative the oppo~ite ~;
sides at tlle inlet end to the longitudinal groove can be similarly tapered so that the inlet end 3a has a dove-tailed shape, The inwardly tapering sides of the longitudinal groove at the inlet end facilitate the introduction of the leading detent 9 into the groove 3 when the first part 1 is moved in a telescoping-like manner into the interior of the second part 2.
At least one disc or washer 11 can be provided within the container having a circumferential peripheral shape 10 adapted to conform or fit the inner surface of the first ;;
part 1. The disc is annular in shape having a central ~
opening complementary to the outer configuration of the object ~-to be packed. Accordingly, the disc provides a spacer between the outer surface of the object being packed and the inner surface of the fir~t part 1. Accordingly, the object is se-cured against lateral displacement within the container after ; ;~
its final assembly. ;

Fig. 4 is a cross section of part 1 in the vicinity of a locking groove or recess 4. This figure shows that longitudinal groove 3 and locking groove 4 are of the same depth, the common base surface 13 running concentrically with the outer wall. Locking groove 4 has an external contour 4a substantially adapted to locking detent 9. Also visible in this section are disc 11, with its central aperture 12, and bosses 15 serving as stops.

The inlet apertures 4b of grooves 4 corresponds approximately to diameter 9a of locking detents 9. However, inlet aperture 4b should preferably be somewhat ;
smaller, the difference depending upon the material used. With . : .
this design, a certain amount of resistance must be overcome when locki~g detents 9 pass through inlet apertures 4b.
Fig. 6 shows~ on an enlarged scale, a detail in the vicinity of longitudinal groove 3, having an alternative arrangement for locking the part 1. Arranged between longi-tudinal groove 3 and locking groove 4 is a roof-shaped projection 14 which runs tangentially in the common base surface of longitudinal groove 3 and locking grooves 4. Pro~ection 14 co-operates radially with base surface 9b of locking detent 9 in order to prevent twisting. The wall of external contour 4a of locking groove 4 is arranged approxi~tely radially.

With the desired length established, the parts 1, 2 are rotated relative to one another about their longitudinal axes so that there is a relative movement of the detents 9 in the direction of the arrow A, note Fig. 1, for securing the detents into the corresponding locking groove 4.
As illustrated in Fig. 1, the detents 9 are circular ~-10 and the locking grooves have a similar shape for receiving and ~' ho}ding the detents. As shown in Fig. 5, starting from the edge of the longitudinal groove 3, each of the locking grooves j 4 has a horse~hoe-shaped contour. The inlet openings from the longitudinal groove 3 into the locking grooves 4 is somewhat -smaller than the diameter of the detents. The dimension of the opening into-the locking grooves 4 depend~ on the material used in forming the container parts, but it is such that a certain .
resistance must be overcome in movinq the detents into and out ~ ;~
of the locking grooves. The opposite surfaces forming the opening into the locking grooves can be arranged in converging relationship from the edge of the longitudinal groove 3 to a point closely ~paced from the longitudinal edge and then the -~
surfaces can diverge again entering into the horseshse-shaped locking groove. As a result, each of the opposite faces forms ; an apex-like arrangement forming a restricted opening into the -~
locking groove 4.
As illustrated in Figure 1, the inlet end 3a of the longitudinal groove 3 at the open end 5 of the first part 1 has a, tapered chamfer surface 10 on one side while the opposite side is rectilinear in aligmnent with the remainder of that '5, . .. .

edge of the longitudinal groove. As an alternative the oppo~ite ~;
sides at tlle inlet end to the longitudinal groove can be similarly tapered so that the inlet end 3a has a dove-tailed shape, The inwardly tapering sides of the longitudinal groove at the inlet end facilitate the introduction of the leading detent 9 into the groove 3 when the first part 1 is moved in a telescoping-like manner into the interior of the second part 2.
At least one disc or washer 11 can be provided within the container having a circumferential peripheral shape 10 adapted to conform or fit the inner surface of the first ;;
part 1. The disc is annular in shape having a central ~
opening complementary to the outer configuration of the object ~-to be packed. Accordingly, the disc provides a spacer between the outer surface of the object being packed and the inner surface of the fir~t part 1. Accordingly, the object is se-cured against lateral displacement within the container after ; ;~
its final assembly. ;
Fig. 2 i8 a section through a locking detent 9 on . part 2. The detent is of circular ¢ro~s section and is in the form of a truncated cone, the major diameter on the inside of part 2 being marked 9a.
Fig. 3 is a view of part 1 as seen from open end 5, the width of longitudinal groove 3 being increased at this end by chamfer 10. Disc 11 has a notch lla and is accurately adapted `
to the internal contour of part 1 in the vicinity of longitudinal groove 3 and locking grooves 4 so that it may be fitted therein.

Fig. 4 is a cross section of part 1 in the vicinity of a locking groove or recess 4. This figure shows that longitudinal groove 3 and locking groove 4 are of the same depth, the common base surface 13 running concentrically with the outer wall. Locking groove 4 has an external contour 4a substantially adapted to locking detent 9. Also visible in this section are disc 11, with its central aperture 12, and bosses 15 serving as stops.
Fig. 5 is a plan view of a poxtion of part 1, showing locking grooves or recesses 4 running from longitudinal groove 3. The external contour 4a of locking grooves 4 is ,-in the form of a horseshoe. The inlet apertures 4b of grooves 4 corresponds approximately to diameter 9a of locking detents 9. However, inlet aperture 4b should preferably be somewhat ;
smaller, the difference depending upon the material used. With . : .
this design, a certain amount of resistance must be overcome when locki~g detents 9 pass through inlet apertures 4b.
Fig. 6 shows~ on an enlarged scale, a detail in the vicinity of longitudinal groove 3, having an alternative arrangement for locking the part 1. Arranged between longi-tudinal groove 3 and locking groove 4 is a roof-shaped projection 14 which runs tangentially in the common base surface of longitudinal groove 3 and locking grooves 4. Pro~ection 14 co-operates radially with base surface 9b of locking detent 9 in order to prevent twisting. The wall of external contour 4a of locking groove 4 is arranged approxi~tely radially.
Disc 11 is provided with a certain amount of play in the ~icinity

facilitates the insertion of disc 11 into part 1. Bosses 15 }
are produced by deformation of the outer wall of part 1.
Fig. 7 shows a further embodiment of part 1 according to the invention. In this case, locking grooves 4, running from longitudinal groove 3, are provided with eXtensions 3 16 running parallel with longitudinal groove 3, the said ex~ensions 16 serving to lock the sleeves or parts 1 and 2 together. Roof-~; shaped projections 14, as in Fig. 6, are also provided to ~ -secure them. In this case, inlet aperture 4b may be somewhat s ~;10~ larger than diameter 9a of locking detents 9. In order to ~;

In Fig. 8 parts 1 and 2 are shown assembled to - ??
form a complete packing unit, closed off by closed ends 6 and 7. '~ -Locking detents 9 engage in locking grooves 4 and prevent the ~;~
parts of the packing from being pulled apart. A disc 11 is inserted into part 1 through open end 5. Disc 11 is in the form of a cup and thus provides a certain spacing from closed ~ - -~20~ end 6. Central aperture 12 corresponds, in cross section, to ~-~the object to be inserted into the packing, in this case a boring and milling tool 18. Disc 11 thus serves to centre the outer end of the shank in the packing container.
As indicated, however, disc 11 may also be arranged -~
in any other appropriate location between open end 5 and closed end 6. In this case a cup-shaped design is of advantage but is not necessary for the particular function of the disc.
In order to allow the air to escape when the con-; *ainer is assembled, and to reduce friction between parts 1 30~ and 2, open end 8 of part 2 has a collar 19 tapering in diameter.
