Description

[Detailed explanation of the invention] (a) Industrial application field This invention is a cartridge-type stick-shaped lipstick container in which the lipstick can be freely replaced, and in particular, several colors of lipstick can be replaced in one outer container. This invention relates to a usable cartridge-type lipstick container.

(b) Conventional technology Cartridge-type lipstick containers generally have a cap,
It is composed of an outer cylinder part that is detachable from the cap, and a cartridge part that is detachable from the outer cylinder part,
The cartridge part includes an inner plate, a guide tube, a spiral groove tube,
It consists of a protective tube. Conventionally, the technique for inserting the cartridge into the outer cylinder involves fixing a leaf spring around the outer cylinder, inserting one end of the cartridge into the spring, and fixing the cartridge using the internal pressure of the leaf spring. was known.

(c) Problems to be solved by the invention The conventional structure in which the leaf spring was fixed to the outer cylinder had the following drawbacks.

When inserting the cartridge part into the leaf spring of the outer cylinder part, (a) when trying to increase the internal pressure of the leaf spring to ensure secure fixation, the cartridge part could not be inserted and removed smoothly. Lipstick containers are generally used by women, and even a slight increase in force can have a big impact on them, which has been a problem. (b) Furthermore, a disadvantage of increasing the internal pressure of the leaf spring is that the leaf spring presses and fixes the end of the outer cylinder of the cartridge, so it slides into contact with the outside of the guide cylinder via the spiral groove cylinder. Accidents were likely to occur in which the protective tube, which had just been inserted, would come off from the spiral groove tube. (c) On the other hand, if the internal pressure of the leaf spring is weakened, there is a drawback that it becomes easy to come off because the leaf spring is fixed only by the friction of the contact. In particular, it has the disadvantage that oils and fats that have adhered to the hands tend to stick to it, and when it gets on it, it is very easy to come off, and there is almost no fixing effect.
(d) Furthermore, it is technically difficult to keep the internal pressure of the leaf spring constant when fixing the leaf spring to the outer cylinder, and (e) the length of the leaf spring must be adjusted to ensure the internal pressure of the leaf spring. Since a certain amount of lipstick is required, the overall length of the container becomes long, which is disadvantageous in that it goes against the manufacturing objective of making the lipstick container lighter and smaller.

(d) Means to solve the problem The cartridge type lipstick container has a cartridge part 1.
and an outer cylindrical part 2 to which the cartridge part 1 is detachably attached.
and a cap 3 which is detachably attached to the outer cylinder part 2. The cartridge part 1 is constructed by sequentially fitting a protection tube 4, a spiral groove tube 5, a guide tube 6, an inner tray 7, and a lipstick 8 inward from the outside. An insertion portion 9 is formed to protrude from the cylinder 5. The insertion portion 9 has a fixing groove 10 recessed around the cylinder having an appropriate interval from the protruding end surface, and a corner portion 11 is formed adjacent to the fixing groove 10 on the main body side of the guide cylinder 6. The outer cylinder portion 2 is composed of an outer cylinder 12 and an intermediate outer cylinder 13. One end of the outer cylinder 12 is formed as a lipstick container end, and the other end is fixed to the inner and outer cylinder 13. At the end of the lipstick container of the outer cylinder 12, a pressing hole 14 is formed by cutting out the central part of the end surface into a shape of an appropriate size, such as a circle or a corner. A flexible thin press plate 15 made of synthetic resin is attached to the inside of the press hole 14. A fixed cover 16 is fixed to the inside of the container end of the outer cylinder 12, and a grip spring 17 is sealed between the fixed cover 16 and the inner surface of the container end of the outer cylinder 12. The fixed cover 16 has a square hole 18 into which the corner 11 of the insertion portion 9 is inserted. The grip spring 17 is entirely formed into a thin cylindrical shape using a thin plate made of a lightweight material such as metal or synthetic resin that has appropriate elasticity. The wall part 19 and the claw part 20 are configured to open and close inwardly and outwardly by bending the wall part 19 and the claw part 20 in the opposite direction to form a claw part 20, and by pressing the cylindrical disk part 21 from the outside or inside. The grip spring 17 is
The fixed cover 16 and the outer cylinder 12 are sealed so that the disk part 21 is located on the pressing hole 14 side and the claw part 20 is located on the square hole 18 side.

(E) Function When inserting the cartridge part 1 into the outer cylinder part 2, the adhesive part 9 of the guide cylinder 6 of the cartridge part 1
It is inserted into the outer cylinder 12. At this time, the wall portion 19 and the claw portion 20 of the grip spring 17 of the outer cylinder 12 are open, and the end surface of the insertion portion 9 passes through the square hole 18 and presses the disk portion 21 from the inside of the grip spring 17. Then, the wall portion 19 and the claw portion 20 of the gripping spring 17 move to close and fit into the fixing groove 10 of the insertion portion 9, thereby fixing the cartridge portion 1 to the outer cylinder portion 2. At this time, the corner 11 of the guide tube 6 and the square hole 18 of the outer tube 12 fit together, so when the protective tube 4 is fixed and the outer tube 12 is rotated, the outer tube 12 and the guide tube 6 rotate as one. Therefore, the lipstick 8 can be put in and taken out reliably. Conversely, when the cartridge part 1 is removed from the outer cylinder part 2, the pressing plate 1 is removed from the pressing hole 14.
5, the disc portion 21 of the grip spring 17 is pressed from the outside. Then, the claw portion 20 of the grip spring 17
is opened and separated from the fixing groove 10, and the cartridge part 1 can be easily removed from the outer cylinder part 2.

(e) Embodiment Next, this invention will be explained based on the drawings of the embodiment. The cartridge type rod-shaped lipstick container includes a cartridge part 1, an outer cylinder part 2 which can be attached to and detached from the cartridge part 1, and an outer cylinder part 2 which is detachable from the cartridge part 1. It consists of a detachable cap 3. The cartridge portion 1 is constructed by sequentially fitting a protection tube 4, a spiral groove tube 5, a guide tube 6, an inner tray 7, and a lipstick 8 inward from the outside. The inner tray 7 has a cylindrical shape with one end open, and a lipstick 8 is inserted and fixed into the open end. The inner plate 7 has a guide protrusion (not shown) protruding from the outside of the cylinder, and is installed inside the guide cylinder 6 so as to be slidable therein. The guide tube 6 has a linear thin groove (not shown).
is bored and rotatably inserted inside the spiral groove tube 5. The protection tube 4 is inserted into the spiral groove tube 5 so as to press it from the outside. One end of the guide tube 6 projects from the protection tube 4 and the spiral groove tube 5 to form an insertion portion 9 . The cylindrical diameter of the insertion portion 9 is formed to be slightly smaller than the main body of the guide tube 6. The insertion portion 9 has a fixing groove 10 formed around the cylinder having an appropriate distance from the protruding end surface. A corner portion 11 is formed adjacent to the fixing groove 10 on the guide cylinder 6 main body side. The corner portion 11 is formed into a polygonal tube shape with an appropriate width on the outer periphery of the tube, and in this embodiment, it is octagonal. The outer cylinder part 2 includes an outer cylinder 12 and a middle outer cylinder 1.
It consists of 3. One end of the outer cylinder 12 is formed as a lipstick container end, and the other end is fixed to an inner and outer cylinder 13, through which the outer cylinder 12 is fitted into the cap 3. The outer cylinder 1
At the end of the lipstick container No. 2, a press hole 14 is formed by cutting the central part of the end surface into a shape of an appropriate size, such as a circle or a corner. A flexible thin press plate 15 made of synthetic resin is attached to the inside or outside of the press hole 14. A fixed cover 16 is fixed inside the container end of the outer cylinder 12, and a grip spring 17 is sealed between the fixed cover 16 and the inner surface of the container of the outer cylinder 12.
