Description

[Detailed Description of the Invention] The present invention relates to a container for dispensing cartridge type cosmetics such as lipsticks and eye pencils.

In a dispensing container equipped with a dispensing mechanism for advancing and retracting bar-shaped cosmetics using a spiral groove, the bar-shaped cosmetics installed at the tip of a sliding member that advances and retreats inside the cylindrical container body is of a cartridge type and is replaceable. The structure is well known. Conventionally, as a cartridge-type container for dispensing bar-shaped cosmetics, there was one in which the tip of the container body was removed and the bar-shaped cosmetic was inserted into the inner tray at the tip of the sliding member, and the other was to protect the bar-shaped cosmetic inserted into the inner tray. In some cases, a cartridge wrapped in a tube is inserted into the container body and connected to a sliding member. The former method involves direct contact with the bar-shaped cosmetic product, which results in dirty hands and often causes damage to the bar-shaped cosmetic product when inserting it into the inner tray or covering it with the tip tube. The latter does not have the same problems as the former because the bar-shaped cosmetic is wrapped in a protective tube, but as disclosed in, for example, Japanese Utility Model Publication No. 58-54219 and Publication No. 56-39455,
The cartridges are connected by forming a thread between the inner plate and the sliding member, or the inner plate is connected to the sliding member by removing the front tube, which makes the structure complicated and it is not only troublesome to attach and remove the cartridge, but also makes it less expensive. It has drawbacks such as not being able to be manufactured.

The present invention eliminates these conventional drawbacks, has a simple structure, allows the cartridge to be easily attached and detached without worrying about breaking the bar-shaped cosmetic, and furthermore allows the inner tray to move forward and backward in a stable manner within the container body. It was devised for the purpose of providing.

That is, the present invention includes a container main body having a rotatable grip cylinder at the base end of the front cylinder and a spiral groove on the inner circumferential surface that rotates together with the grip cylinder; A cartridge-type rod-shaped cartridge consisting of a sliding member that moves forward and backward together, and a cartridge in which a stick-shaped cosmetic whose base is inserted into an inner plate is wrapped in a protective tube, and the inner plate is attached to and detached from the tip of the sliding member. In the container for dispensing cosmetics; the sliding member is tightly fitted into the container body so that the tip protrudes from the tip surface of the tip tube when the sliding member is moved forward most; the inner tray is fitted outwardly. The sliding member has an insertion protrusion having an expanding locking protrusion at its base end; the sliding member has an enlarged hole portion and an insertion hole at its distal end in which the locking protrusion and the insertion protrusion are tightly fitted; The distal end portion is divided into a plurality of parts by a cut groove; the proximal end of the protection tube is fitted and supported by the inner plate, and the inner plate is connected to the sliding member and pulled into the container body. When it is loaded, it hits the tip end surface of the tip cylinder and is separated from the inner tray.

Next, a specific example of the present invention will be explained based on the drawings.

In the figure, reference numeral 1 denotes a container main body, in which approximately half the length of the distal side of a core tube 3 having a guide groove 2 extending in the axial direction over approximately half the length of the proximal side is press-fitted into the front tube 4, and the inner peripheral surface A guide tube 6 having a spiral groove 5 on the
is rotatably mounted over approximately half the length of the proximal end of the core tube 3, and is guided between the step portion 3a formed by expanding the proximal end of the core tube 3 outward and the front tube 4. A cylinder 6 is held, and a bottomed knob cylinder 7 is placed over the guide cylinder 6 and fixed by crimping.

Reference numeral 8 denotes a sliding member, which is formed in the shape of a round bar, and has a guide protrusion 9 at its base end that passes through the guide groove 2 and fits into the spiral groove 5, and is tightly fitted and built into the core tube 3. ing. This sliding member 8 is fitted onto the core tube 3 before covering the guide tube 6, and has an insertion hole 10 formed at its tip and a large diameter enlarged hole in the middle of the insertion hole 10. A section 11 is provided, and this tip section is divided into two by a cut groove 12.

13 is a cartridge, and a bar-shaped cosmetic 14
The base of the rod-shaped cosmetic 14 is inserted and fixed into the inner plate 15, and the base end of the bar-shaped cosmetic 14 is enclosed in a protective cylinder 16 which is fitted and supported by the inner plate 15. An insertion protrusion 17 that is tightly fitted into the insertion hole 10 is formed protruding from the base end of the inner plate 15.
A flange-like locking protrusion 18 that tightly fits into the enlarged hole 11 is provided at the middle portion of the holder.

In this specific example configured in this way, by rotating the knob cylinder 7, the guide cylinder 6 rotates integrally,
A guide protrusion 9 screwed into a spiral groove 5 on the inner circumferential surface moves the sliding member 8 forward and backward without rotating due to the anti-rotation action of the guide groove 2. The tip protrudes from the tip surface of the front tube 4 as shown in FIG.

The cartridge 13 can be attached or detached in this state, and since the protruding tip is divided by the cut groove 12, it can be freely expanded by its own elastic force, and the insertion protrusion 17 can be inserted into the insertion hole 10. When inserted into the cartridge, the locking protrusion 18 pushes out the tip and is inserted into the enlarged hole 11, thereby connecting the sliding member 8 and the cartridge 13 as shown in FIG. . When the inner plate 15 is pulled, the locking protrusion 18 expands its tip and is pulled out from the enlarged hole portion 11 and the insertion hole 10, allowing the inner plate 15 to be separated from the sliding member 8.

Next, when the cartridge 13 is connected to the sliding member 8 and the knob tube 7 is rotated to move the sliding member 8 backward, the inner tray 15 and the cosmetic bar 14 are moved back together with the sliding member 8. The protective tube 16 is inserted into the core tube 3, hits the tip end surface of the front tube 4, and is removed with the bar-shaped cosmetic material 14 being pulled out as shown in FIG. When the sliding member 8 is moved back the most, the rod-shaped cosmetic material 14 is completely inserted into the core tube 3 as shown in FIG. use.

At this time, the sliding member 8 is tightly fitted into the core tube 3, and the locking protrusion 18, the insertion protrusion 17 is inserted into the enlarged hole 11,
Since it is tightly fitted into the insertion hole 10, the sliding member 8
The inner plate 15 can be reliably connected without causing any inconvenience such as fatigue due to repeated irregular expansion and contraction of the divided tips of the inner plate 15 or the inner plate 15 coming off due to an impact. It allows for stable advancement and retreat.

When replacing it, the sliding member 8 should be moved forward as shown in FIG. 1, and the inner plate 15 should be pulled out.

FIG. 5 shows a different specific example of the coupling mechanism between the sliding member 8 and the cartridge 13, in which an enlarged hole 21 is provided at the bottom of the insertion hole 20, and the tip of the sliding member 8 has a cut groove. A truncated cone-shaped locking projection 28 is formed at the tip of an insertion projection 27 that is divided into two by 12 and protrudes from the base end of the inner plate 15. They are connected by fitting into 21.

It goes without saying that the design of the feeding mechanism using the spiral groove 5 may be changed to various known mechanisms, and the tip of the sliding member 8 may be divided into three or four pieces.

As is clear from the above description, according to the present invention, the insertion protrusion formed protruding from the inner plate of the cartridge is inserted into the insertion hole formed at the tip of the sliding member built into the container body, and the divided tip The locking protrusion is fitted into the enlarged hole by utilizing the fact that it protrudes from the front tube when it is most advanced and expands and restores itself elastically. Cartridges can be attached and detached with simple operations. When the inner tray is connected to the sliding member and moved backward, it is confirmed that the sliding member is tightly fitted into the container body, and that the locking protrusion and the insertion protrusion are in the enlarged hole.
Since it is tightly fitted into the insertion hole, the inner plate can be moved forward and backward stably without fear of coming off, and there is also no fear of breaking the bar-shaped cosmetic. Furthermore, when the inner plate is connected to the sliding member and the protective tube encasing the bar-shaped cosmetic is drawn into the container body, it collides with the front tube and separates from the inner plate, so there is no need to touch the bar-shaped cosmetic when connecting and get your hands dirty. It can be handled without breaking and the protective tube can be removed very easily. Further, since the cartridge is constructed of an inner plate and a protective tube, there is an advantage that the number of parts is small and it can be provided at a low cost. That is, according to the present invention, a feeding container is provided which has a simple structure and allows easy attachment and detachment of cartridges.
