Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a twin-type stick-shaped material extending container comprising a base-sleeve which is provided with two extending and withdrawing mechanisms at both ends of the base-sleeve. 2. Description of the Prior Art A conventional stick-shaped material extending container comprises a tubular body provided with a rotary sleeve having an inner spiral threaded groove around the periphery of the tubular body in such a manner that the rotary sleeve cannot travel in an axial direction, but can be rotatable. The tubular body has an axial guide groove. A stick-shaped material holder is inserted into the tubular body with a retaining piece of the stick-shaped material holder being inserted into the guide groove. A projection on the retaining piece is inserted into the spiral threaded groove of the rotary sleeve. In a conventional container, when the rotary sleeve is turned on the tubular body, a stick-shaped material held by the retaining piece on the stick-shaped material holder is extended or withdrawn the rotary sleeve according to the direction of rotation of the rotary sleeve. When the usable portion of the stick-shaped material is used up, the rest of the stick-shaped material is removed from the rotary sleeve by pulling out of the rotary sleeve with the rest of the stick-shaped material with one's finger. However, since the conventional container is not a twin-type container, the thickness of the stick-shaped material is fixed. It is impossible to properly use a thin or thick stick-shaped material according to the thickness or size of line drawing or pattern. Further, in case of a lipstick or retouching stick, it is difficult to hold a new lipstick or retouching stick in the retaining piece of the stick-shaped material holder while the used up lipstick or retouching stick is changed because the fingers are stained by the new lipstick or retouching stick, so the lipstick or retouching stick which has become used up becomes disused together with the container thereof. Therefore the lipsticks or retouching sticks are high-priced. US-A-2 710 614, which discloses the preamble of claim 1, discloses a container with two stick-shaped material holders to be extended and withdrawn independently. Protrusions are provided on the carrier members respectively. These protrusions each extend through longitudinal slots provided in an inner tubular member and engage with corresponding helical slots in the sleeve members. Because of the arrangement of the inner tubular members and their annular beads with respect to the sleeve members it is impossible to extend the carrier members fully in order to be replaced by new ones holding unused material. Therefor it is necessary to remove the used up material, the carrier member still being inside the sleeves. A further disadvantage of the holder according to US-A-2 710 614 is the fact that the protrusion being engaged with the helical slot has to extend through the longitudinal slot. The engagement with the helical slot requires a relatively small protrusion in the axial direction of the holder but relatively long in its radial direction. Therefor only a small protrusion engages with the longitudinal slot and there exists the risk the protrusion being broken when the sleeve member and the tubular member are rotated relatively. BRIEF SUMMARY OF THE INVENTION It is an object of the invention to provide a twin-type stick-shaped material extending container in which it is possible to properly use a thin or thick stick-shaped material on either end according to the thickness or size of line drawing or pattern needed and it is possible to change unused stick-shaped material for new stick-shaped material. It is another object of the invention to provide a twin-type reversible stick-shaped material extending container in which it is possible to properly use a thin or thick stick-shaped material according to the thickness or size of line drawing or pattern needed and it is possible to change unused stick-shaped material for new stick-shaped material and which is childproof. The above-mentioned first object is attained by a twin-type stick-shaped material extending container comprising: a base sleeve having first and second concave inner end portions at both end portion of the base sleeve, respectively. First and second rotary guide sleeves have first and second raised portions, respectively, said first and second rotary guide sleeves being inserted in to said concave inner end portions of said base sleeve so as to be rotatable with regard to the base sleeve and detachable in the axial direction from the base sleeve. A first traveling body has a first stick-shaped material receiving base fitted slidably in the first rotary gide sleeve and a second traveling body has a second stick-shaped material receiving base fitted slidably in a second rotary guide sleeve, wherein the first traveling body is inserted in the second traveling body, and said first and second traveling bodies are arranged in said base sleeve. First and second spiral thread grooves are formed on peripheries of said first and second traveling bodies into which said first and second raised portions are inserted. First rotation-prevention means are provided on said first traveling body and a second rotation-prevention means on said second traveling body. The first rotary guide sleeve is capped with a first inner cap, while the second rotary guide sleeve is capped with a second inner cap. First and second outer caps are detachably attached to said first and second inner caps. In the above-mentioned twintype stick-shaped material drawing-out container, when a line drawing or pattern is thin or small, the first and the second inner caps are detached from the base sleeve, and the first rotary guide sleeve is turned. Since the first raised portion is inserted into the first spiral threaded groove and the direction of rotation of the first guide sleeve is regulated by the rotation-prevention means, a thin stick-shaped material can be extended into the end of the first rotary guide sleeve by sliding the first stick-shaped material receiving base along the inside of the first rotary guide sleeve according the direction of rotation of the first rotary guide sleeve. Further when a line drawing or pattern is thick or large, the second inner and outer caps are detached from the base sleeve, and the second rotary guide sleeve is turned, causing the thick stick-shaped material to be extended into the end of the second rotary guide sleeve according the direction of the second rotary guide sleeve. As the container according to the invention is of twin-type, thin or thick stick-shaped materials can be used properly according to the thickness or size of a line drawing or pattern. Further, the set of the first rotary guide sleeve and the first traveling body having the first stick-shaped material receiving base engaged slidably with the inside of the first rotary guide sleeve can be handled as a first cassette. The set of the second rotary guide sleeve and the second traveling body having the second stick-shaped material receiving base engaged slidably with the inside of the second rotary guide sleeve can be handled as a second cassette. Accordingly, when a stick-shaped material of lipstick or retouching stick is used up, the first and second cassettes to be replaced can be changed for new first and second cassettes in which new stick-shaped material is contained, so the container is reusable. Since the first rotary guide sleeve is capped with first inner and outer caps while the second rotary guide sleeve is capped with the second inner and outer caps, the first and second rotary guide sleeves are prevented from being operated by mistake. Therefore, stick-shaped materials are prevented from colliding with the first and second inner caps so that the stick-shaped materials are not broken and bent. The above-mentioned second object is attained by the above-mentioned twin type stick-shaped material extending container according to the invention, said twin-type stick-shaped material drawing-out container further comprises air vent holes formed between the first inner and outer caps and between the second inner and outer caps respectively. Even if a baby or a child should swallow by mistake the first outer cap with the first inner cap or the second outer cap with the second inner cap and either of them become caught in the throat, the baby or child can breathe through the air vent hole formed between the first inner and outer caps or the second inner cap and the second outer cap, till the baby or the child receives treatment. Since a cap is a double cap comprised of the first inner and outer caps or the second inner and outer caps, various caps can be formed by modification of the first outer cap and the second outer cap.

DETAILED DESCRIPTION Referring now to Fig. 1, there is shown a first embodiment of a twin-type or reversible stick-shaped material extending container which is comprised of base sleeve 3 and first and second rotary guide sleeves 6, 7. Base sleeve 3 has first and second projections 1, 2 and first and second concave inner end portions 4, 5, and first and second rotary guide sleeves 6, 7 having first and second raised portions 14, 15. First and second rotary guide sleeves 6, 7 are inserted into first and second cocave inner end portions 4, 5, respectively. For example concave portions 24 formed on first and second concave inner end portions 4, 5 are engaged with convex portions 25 formed on first and second rotary guide sleeves 6, 7, so as to be rotatable relative to base sleeve 3 and detachable from base sleeve 3. First traveling body 10 and second traveling body 11 inserted into and are arranged in base sleeve 3, wherein first traveling body 10 is formed with first stick-shaped material receiving base 8 fitted slidably in first rotary guide sleeve 6, 7 and second traveling body 11 is formed with second stick-shaped material receiving base 9 fitted slidably in second rotary guide sleeve 7. O rings 26A, 26B acting as seals preventing retouching sticks 22, 23 from becoming dried out are inserted between first stick-shaped material receiving base 8 and first rotary guide sleeve 6, and between second stick-shaped eraser receiving base 9 and second rotary guide sleeve 7, respectively. First and second traveling bodies 10, 11 are formed with first spiral thread grooves 12, 13 into which first and second raised portions 14, 15 are inserted respectively, and with first and second axial grooves 16, 17 into which first and second projections 1, 2 are inserted respectively(Fig. 2). First traveling body 10 may be a tubular or pillar-shaped body. The set of first rotary guide sleeve 6 and first traveling body 10 having first stick-shaped material receiving base 8 slidably fitting in first rotary guide sleeve 6 and the set of second rotary guide sleeve 7 and second traveling body 11 having second stick-shaped material receiving base 9 slidably fitted in second rotary guide sleeve 7 can be handled as first and second cassettes. First rotary guide sleeve 6 is detachably capped with first inner cap 20A having first antidry agent 18 while second rotary guide sleeve 7 is capped with second inner cap 21A having second antidry agent 19. Air vent hole 27 is formed between first inner cap 20A and first outer cap 20B detachably attached on first inner cap 20A, outside one end of base sleeve 3. Air vent hole 28 is formed between second inner cap 21A and first outer cap 21B detachably attached on first inner cap 21A(Fig. 5). Base sleeve 3 has a tooth formed of up portions 29A and down portions 29B at both end portions of base sleeve A, while first and second outer caps 20B, 21B are formed with a tooth formed of up portion 30A and down portion 30B at both the inner end portions of first and second outer caps 20B, 21B. Up portions 29A of base sleeve 3 engage with down portions 30B, while down portions 29B of base sleeve 3 engage with up portions 30A. When first and second outer caps 20B, 21B are to be detached from base sleeve 3, first and second outer sleeves 20B, 21B are turned with regard to base sleeve 3, allowing first and second outer sleeves 20B, 21B to be detached easily from base sleeve 29. Use can be made of a fiber made of synthetic resin such as polyester, polyacetate, or elastic material including sponge rubber, acrylic ester resin and others, for first and second antidry agents 18, 19, particularly when stick-shaped material 22, 23 are, for example, retouching sticks from which moisture easily vaporizes. At this time, when eraser stick is dried and becomes unfit for use because base sleeve 3 has been left uncapped, base sleeve 3 is capped with first and second antidry agents 18, 19 soaked with water, and retouching sticks are supplied with water to become usable. First and second antidry agents 18, 19 act also as a cushion for stick-shaped materials, since first and second antidry agents are made of elastic materials as above-mentioned. Further, the heads of first inner cap 20A, first outer cap 20B, second inner cap 21A and second outer cap 21B have shapes such as a round shape for use as a spatula. In the above-mentioned embodiment, when a line drawing or pattern is thin or small, first inner cap 20A and first outer cap 20B are detached from base sleeve 3. First rotary guide sleeve 6 is rotated relative to base sleeve 3, allowing thin retouching stick 22 to be extended from the head of first rotary guide sleeve 6. First raised portion 14 of first rotary guide sleeve 6 is inserted in first spiral thread groove 12 of first traveling body 10, and first projection 1 is inserted in first axial groove 16. Thus the rotation of first rotary guide sleeve 6 makes first stick-shaped material receiving base 8 slide into first rotary guide sleeve 6 so that thin retouching stick 22 is extended from the head of rotary guide sleeve 6 according to the direction of rotation of first rotary guide sleeve 6 as first stick-shaped material receiving base 8 slides into first rotary guide sleeve 6. On the other hand, when a line drawing or pattern is thick or large, second inner cap 21A and second outer cap 21B are detached from base sleeve 3, and second rotary guide sleeve 7 is rotated relative to base sleeve 3, allowing thick retouching stick 23 to be extended from the head of second rotary guide sleeve 7: second raised portion 15 of second rotary guide sleeve 7 is inserted in second spiral thread groove 13 of second traveling body 11, and second projection 2 is inserted in first axial groove 17, and so the rotation of second rotary guide sleeve 7 makes second stick-shaped material receiving base 9 slide into second rotary guide sleeve 7 so that thick retouching stick 23 can be drawn out of the head of second rotary guide sleeve 7 according to the direction of rotation of rotary guide sleeve 6 as second stick-shaped material receiving base 9 slides into second rotary guide sleeve 7. Accordingly, thin retouching stick 22 and thick retouching stick 23 are extended from the heads of first and second rotary guide sleeves 6, 7 respectively and can be used properly according to the thickness or size of line drawing or pattern, and retouching of the figures can be performed smoothly and quickly without failure. Further, as for the retouching stick, since the heads of caps 20A, 20B, 21A, 21B have shapes such as a round shape suited for use as a spatula. After erasing has been performed, smooth rewriting or repainting can be performed by using the heads of caps 20A, 20B, 21A, 21B as spatulas. In this embodiment, a set comprised of first rotary guide sleeve 6 and first traveling body 10 having first stick-shaped material receiving base 8 capped with first rotary guide sleeve 6, and a set comprised of second rotary guide sleeve 7 and second traveling body 11 having second stick-shaped material receiving base 9 capped with second rotary guide sleeve 7 can be handled as first and second cassettes. Therefore, even though the stick-shaped material is lipstick or retouching stick, and has been used up stick-shaped materials 22, 23, unusable the first and second cassettes can be changed for a new first and second cassettes in which new stick-shaped materials are contained, so the container is reusuable. First rotary guide sleeve 6 is operated by rotation and is capped with first inner cap 20A, and first outer cap 20B, while second rotary guide sleeve 7 operated by rotation is capped with second inner cap 21A, and second outer cap 22B. Thus the first and second rotary guide sleeves 6 and 7 are prevented from being operated by mistake. Accordingly, stick-shaped materials 22, 23 are prevented from colliding with first and second inner caps 20a, 21B so that the stick-shaped materials are prevented from being broken and bent. Even though a baby or a child should swallows first outer cap 20B with first inner cap 20A or second outer cap 21B with second inner cap 21A and the first outer and inner caps or the second outer and inner caps are caught in one's throat, a baby or child can breathe through the air vent hole formed between the first and second outer caps, till the baby or the child receives treatment. Since caps are double caps comprised of first inner cap 20A and first outer cap 20B or of second inner cap 21A and second outer cap 21B, various caps can be formed by the modification of first outer cap 20B and second outer cap 21B. Further, when stick-shaped materials 22, 23 are retouching sticks, retouching fluid is packed in first stick-shaped material receiving base 8 and the inside of first rotary guide sleeve 6, and in second stick-shaped material receiving base 9 and second rotary guide sleeve 7, and a formed insert is made. Thereafter, first and second rotary rotary guide sleeves 6, 7 are capped with first inner cap 20A and first outer cap 21 A, by which retouching sticks are prevented from being dried up. Parts which can be stained by retouching fluid when packing an erasing fluid are covered with first and second outer caps 20B and 21B. Therefore, even though the parts are stained by retouching fluid, it is not necessary to care about being parts stained by retouching fluid. It goes without saying that use can be made of a stick-shaped eraser rubber, lipstick and others as well as a retouching stick. In the invention, rotation-prevention means is not limited to one comprised of first and second projections 1, 2 and first and second longitudinal groove 16, 17 into which first and second projections 1, 2 are inserted. Means for preventing rotation such as polygonal part engaged with each other could also be used. This invention is not limited by the embodiment shown in the drawings and described in the description, which is given by way of example and not of limitation, but only in accordance with the scope of the appended claims.
