Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement in a dispensing container in which a stick-shaped cosmetic such as lipstick is dispensed by rotating the container.

[Conventional technology]

In general, this type of feeding container includes a spiral tube with a spiral groove formed on its inner peripheral surface, a guide tube that is rotatably inserted into the spiral tube and has a long hole extending along the axis, and a guide tube that is rotatably inserted into the spiral tube and has a long hole extending along the axis. and a saucer formed with a protrusion that engages with the spiral groove through the long hole of the lipstick.For example, when a lipstick is fitted into the saucer and the spiral tube and guide tube are rotated relative to each other, the lipstick is held in the saucer. The applied lipstick is dispensed from the tip of the container.

FIGS. 3 and 4 show an example of the structure of such a dispensing container.

That is, the dispensing container shown in FIG.
a guide cylinder 4 in which a long hole 3 is formed which is rotatably inserted and extends in the vertical direction (vertical direction in FIG. 3);
and an inner plate 6 formed with a protrusion 5 that engages with the spiral groove 1 through the elongated hole 3 of the guide tube 4.
As shown in the illustrated example, a bar-shaped solid cosmetic A (for example, lipstick) is fitted into the inner tray 6, so that the inner tray 6 can be drawn out when the spiral tube 2 and the guide tube 4 are rotated relative to each other. It is something.

Incidentally, in the case of a cosmetic container where appearance is important, it is desirable that the elongated hole 3 of the guide tube 4 is not visible even when viewed from above after an outer tube (not shown) is attached to the dispensing container. On the other hand, in terms of assembly work, it can be said that it is extremely efficient to have the elongated hole 3 reach the upper end face and open so that the protrusion 5 of the inner plate 6 can be fitted therein. Therefore, it would be ideal to design the position of the end of the elongated hole 3 of the guide tube 4 so as to satisfy these requirements, but since these requirements are contradictory, this cannot be achieved, and both requirements cannot be achieved. Considering this, only one of the elongated holes 4 was opened to the upper end surface.

However, the fact that one of the elongated holes 4 is open does not give a satisfactory appearance. Also,
During assembly work, the long hole 4 must be widened from the opening and the inner plate 6 inserted, and then the opening must be narrowed again to reduce the diameter of the long hole 4 and inserted into the spiral tube 2. However, it is still a hindrance to work.

The dispensing container shown in FIGS. 5 to 7 has been devised to satisfy both of the above-mentioned contradictory requirements for the guide tube.

In other words, the feeding container shown in Fig. 5 is
-9533, which is
The two elongated holes 3 of the guide cylinder 4 are not opened at the upper end surface, but are opened at the lower end surface, and the protrusion 5 of the inner plate 6 is opened.
In addition, a locking protrusion 7 is provided at the lower end of each division of the guide tube 4 divided by two elongated holes 3 to protrude outward in the radial direction, and the locking protrusion 7 can be engaged with and detached from the guide tube 4. A bottom cover 9 having an arc-shaped hole 8 at the lower end corner that engages with the guide cylinder 4 is fitted onto the lower outer periphery of the guide cylinder 4, so that the opening of the elongated hole 3 is not visible from above.

Since the elongated hole 3 of the guide tube 4 does not reach the upper end surface of the dispensing container constructed in this manner, the elongated hole 3 cannot be seen at all even if the container is placed in the outer tube and viewed from above. Also, when assembling, the two elongated holes 3 of the guide tube 4 reach the lower end surface and are open, so the protrusion 5 of the inner plate 6 can be inserted into the elongated hole 3 without opening the elongated holes 3 as in the conventional case. Easy to mate
It has good assembly workability.

[Problem that the invention attempts to solve]

However, although the dispensing container with the above structure can satisfy the appearance from above, on the other hand, a locking protrusion 7 is provided at the lower end of the guide tube 4, and an arc-shaped hole 8 that engages with this protrusion 7 is formed in the bottom cover. Since the container is formed at the lower corner of the container 9, the appearance from below is impaired, and as a result, the appearance of the entire container is unsatisfactory. Therefore, it cannot be said to be suitable for containers for cosmetics and the like where appearance is important.

The dispensing container of the present invention was developed in view of the above circumstances, and the purpose is to provide a dispensing container that satisfies both the appearance of the entire container, including not only from above but also from below, and ease of assembly. There is.

``Means for Solving the Problems'' The dispensing container of the present invention has a guide cylinder having a dispensing port for a bar-shaped cosmetic at its tip and an elongated hole extending in the axial direction and opening at the lower end in the peripheral wall. a helical tube which is inserted into the outer circumference of the guide tube so as to be rotatable around an axis and has a helical groove formed on the inner circumference; and a helical tube which is inserted into the guide tube so as to be able to rise and fall freely and engages with the helical groove through an elongated hole. a bottom lid having a stepped portion that abuts the lower end of the helical tube and a small diameter portion that is fitted into the inner periphery of the guide tube; A locking hole is formed on the outer circumferential surface, and a locking protrusion that locks in the locking hole and a guide protrusion that fits into the elongated hole when both of these are in a locked state are formed on the outer peripheral surface of the small diameter portion. It is characterized by the fact that it is provided.

〔Example〕

Hereinafter, one embodiment of the dispensing container of the present invention will be described with reference to FIGS. 1 and 2.

In the figure, numeral 10 is a guide cylinder, numeral 11 is a helical cylinder that is rotatably inserted into the outer periphery of the guide cylinder 10, and numeral 12 is a spiral cylinder that is inserted into the guide cylinder 10 so as to be movable up and down, and the relative position between the guide cylinder 10 and the helical cylinder 11 is An inner plate 13 that is moved in the axial direction of the guide tube 10 (vertical direction in FIG. 1) by rotation is a bottom cover that comes into contact with the spiral tube 11 and is fitted into the inner periphery of the guide tube 10. 13 constitutes the main component of the dispensing container of the present invention.

The guide tube 10 is formed of synthetic resin or the like in a cylindrical shape, and has a dispensing port 14 for the rod-shaped cosmetic A at its tip.
It has the following.

A locking piece 14a is provided on the outer periphery of the upper end of the guide tube 10 to prevent the spiral tube 11 from moving upward. Further, two elongated holes 15 extending in the axial direction (up and down) are provided in the opposing outer peripheral walls. The upper ends of these long holes 15 are dead ends, and locking grooves 15a facing in the circumferential direction are connected thereto. One of the lower ends of the elongated holes 15 is open reaching the lower end surface of the guide tube 10, and a locking groove 15a facing in the circumferential direction is continuously provided in the middle thereof. In addition, the guide tube 10
A locking hole 16 for locking the bottom cover 13 inserted from below is formed at the lower end of the housing.

Spiral tube 1 fitted onto the outer periphery of this guide tube 10
A spiral groove 17 is formed on the inner periphery of 1.

The inner plate 12 holding the bar-shaped cosmetic A has two protrusions 18 protruding from the upper outer circumferential surfaces facing each other to engage with the spiral groove 17 through the elongated hole 15. The diameter of the lower part of the inner plate 12 is reduced so that the lower surface does not come into contact with the upper surface of the bottom lid 13.

The bottom cover 13 is composed of a small diameter part 13a, a medium diameter part 13b, and a large diameter part 13c in order from the top. The bottom cover 13 is fitted into the lower inner periphery of the guide cylinder 10 with its small diameter part 13a in such a state that the upper surface (step) 13d of the medium diameter part 13b is in contact with the lower surface of the spiral cylinder 11.

A locking projection 19 that engages with the locking hole 16 of the guide tube 10 and a guide projection 20 that fits into the elongated hole 15 in the locked state of both are provided on the outer peripheral surface of the small diameter portion 13a. There is. Furthermore, a locking rib 21 is provided on the outer circumferential surface of the medium diameter portion 13b for locking a cylindrical lid (not shown) that is fitted from above.

As shown in FIG. 1, a guide tube 10, a spiral tube 1
1.Incorporate each member such as the inner plate 12 and the bottom cover 13,
The bar-shaped cosmetic A is housed in an inner tray 12, and this is fed into the guide cylinder 10, to complete the assembly of the dispensing container containing the bar-shaped cosmetic A.

When using the bar-shaped cosmetic A installed in the inner tray 12, hold the spiral tube 11 and rotate the bottom cover 13 to separate the spiral tube 11 and the guide tube 10.
The bar-shaped cosmetic A can be fed out by relatively rotating the rollers, pushing the protrusion 18 of the inner plate 12 upward by the spiral groove 17, and moving the inner plate 12 toward the tip.

In addition, when the helical tube 11 and the guide tube 10 are rotated relative to each other by holding the helical tube 11 and rotating the bottom cover 13 in the opposite direction to the above operation, the helical groove 18 touches the protrusion 18 of the inner plate 12. Since it is pushed toward the lower end, the cosmetic A integrally attached to the inner tray 12 is returned toward the lower end and accommodated in the guide cylinder 11.

As explained above, the dispensing container of this example is
A locking hole 16 is formed at the lower end of the guide tube 10, a locking protrusion 19 is formed on the outer peripheral surface of the small diameter portion 13a of the bottom cover 13, and a locking protrusion 19 locks into the locking hole 16. The structure includes a guide protrusion 20 that fits into the guide protrusion 20. Therefore, when this dispensing container is assembled, both the locking protrusion 19 and the guide protrusion 20 are completely invisible from the outside, and the guide tube 10 and the bottom cover 13 cannot be rotated and cannot be separated from each other up or down without damaging the appearance. It can be done. Therefore, it can be said that it is a suitable container for cosmetics where appearance is important. Also, when assembling, the long hole 15 of the guide tube 10 reaches the lower end surface and is open, so the inner plate 1
The second protrusion 18 can be easily fitted into the elongated hole 15. Therefore, assembly workability is good.

Therefore, the dispensing container of this embodiment can satisfy both the appearance and the ease of assembly.
