Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a dispensing container for stick-shaped cosmetics such as lipsticks.

[Conventional technology and its technical problems]

As a feeding container for stick-shaped cosmetics such as lipsticks and ticks, a grooved tube fitted with a hakama and one piece or a lower part,
A combination structure of a middle plate having a projection that fits in the vertical groove of the grooved cylinder, a spiral cylinder that guides the projection protruding from the vertical groove of the middle plate, and a cap that is externally fitted to the spiral cylinder is well known.

In recent years, such a feeding container is often made of synthetic resin not only for a cap and a hook, but also for a feeding mechanism such as a grooved tube, a spiral tube, and a middle plate. Thus, the delivery container made of synthetic resin has advantages such as low product cost and light weight. However, on the other hand,
Since the surface is smooth, the resistance (rotation torque) is small and the inner plate moves up and down with a slight force when the spiral tube and the hakama are relatively rotated in order to dispense the cosmetic and lower it. For this reason, there is a problem that the feeling of operation is poor and the feeling of luxury is poor, and the vibration of the transportation and transportation naturally raises the inner plate and the cosmetics collide with the inner bottom surface of the cap. There was a problem that is likely to occur.

As a countermeasure against this, various proposals have heretofore been made. For example, Japanese Utility Model Publication No. 57-16496 and Japanese Utility Model Application Publication No. 58-112216 disclose that an inner plate is cut to form an elastic piece, or a dowel is formed. It has been proposed to provide a resistance by using them. Also, Japanese Utility Model Publication No. 57-32809 proposes a grooved cylinder provided with several vertical strips running in the axial direction on the inner peripheral surface thereof.

However, since these prior arts have a local contact resistance, the deformation acts locally, and even if the resistance is large at the beginning, a force more than the stress strain resistance is applied to cause permanent deformation over time, There was a problem that the effect weakened or disappeared in a short period of time and a problem that rotation was inevitable.

In addition, Japanese Utility Model Laid-Open No. 56-111906 and Japanese Utility Model Laid-Open No. 59-141910 propose to provide a peripheral groove in the lower part of the grooved cylinder and to fit a C-shaped elastic body in this groove. Since parts are required, the cost is high, and because local resistance is created, there is a problem that the effect is weakened over time.

In addition, it has been proposed to add resistance to the grooved tube or spiral tube to increase resistance due to viscosity, but when used at high temperatures, grease flows out, and expensive cosmetics are contaminated. It was problematic and impractical.

[Means for Solving the Problems]

The present invention was devised in order to solve the above-mentioned conventional problems, and the purpose thereof is to ensure a long-term reduction with little change with a very simple structure without using special parts. An object of the present invention is to provide a practical delivery container for lipstick or the like, which can have a stable rotation torque and can be smoothly moved up and down without any play during rotation.

In order to achieve the above object, the present invention provides a grooved cylinder having a pair of vertical grooves, an intermediate plate having a protrusion that fits into the vertical groove of the grooved cylinder, and an outer plate that is externally fitted to the grooved cylinder. In a case where a spiral tube having a spiral groove for guiding the protrusion of the inner plate is provided, the entire grooved tube is brought into close contact with the spiral tube by providing a spring effect that tries to spread in the radial direction, and the resistance of the wide area is increased. The action is to create a feeling of rotation.

That is, the feature of the present invention is that at least one vertical groove of the grooved cylinder in a single state before assembly is expanded toward the upper side so that the diameter of the grooved cylinder increases toward the upper side. The shape is increased, and the grooved cylinder is fitted into the spiral cylinder to forcibly reduce the diameter so as to be in close contact with the spiral cylinder.

The present invention therefore includes a configuration in which both vertical grooves widen upwards, in which case the grooved tube is divided into a pair of arcuate pieces, and the arcuate pieces are spaced apart in the upward direction. Become.

〔Example〕

 An embodiment of the present invention will be described below with reference to the accompanying drawings.

1 to 4 show a first embodiment of a feeding container for synthetic resin lipstick and the like according to the present invention, and FIGS. 6 to 8 show a second embodiment.

In FIG. 1, reference numeral 1 is a hook, which is composed of a peripheral wall having a required height and a bottom wall formed at the lower end of the peripheral wall.

Numeral 3 is made of synthetic resin like other parts, and is a grooved cylinder, and the lower part has a large-diameter concave and convex base 31 to be fitted into the hakama 1.
A vertical cylinder 32 is provided above the uneven base portion 31, and the vertical cylinder 32 has bent grooves in the upper and lower portions in the circumferential direction.
A pair of vertical grooves 33, 33 'that connect 34 are formed at 180-degree symmetrical positions.

Reference numeral 4 denotes an inner plate which is installed in the grooved cylinder 3 and which has a concave portion into which a rod-shaped cosmetic A such as lipstick is fitted and which has an axial projection 41 which fits in the vertical grooves 33, 33 'of the grooved cylinder 3 on the outer periphery. , 41 are formed.

Reference numeral 5 is a spiral cylinder externally fitted to the vertical cylinder 32 of the grooved cylinder 3 so as to allow relative rotation with the vertical cylinder 32.
A spiral groove 51 that guides 41, 41 is formed. 6 is a cap.

Although the above construction is similar to that of a conventional dispensing container for lipstick or the like, the present invention makes the entire vertical cylinder 32 of the grooved cylinder 3 have a spring effect so as to be in close contact with the spiral cylinder 5.

That is, in the first embodiment, one of the vertical grooves 33 'has the same width from the upper end to the lower end, and the lower end is a constant width groove continuous with the bending groove 34, but the other vertical groove 33 has the same width. Differently, the lower end 33a of the edges 330, 330 forming the vertical groove passes through the bending groove 34 to reach the uneven base portion 31, and has a predetermined opening angle so as to have a trumpet shape or a V shape from the lower end 33a to the upper end 33b. As a result, the vertical cylinder 32 gradually increases in diameter toward the upper end with respect to the diameter D _{1 at the} lower end, and has a maximum diameter D ₂ at the upper end.

In the second embodiment, both of the pair of vertical grooves 33, 33 are expanded at a predetermined angle from the lower end 33a to the upper end 33b, so that the vertical cylinder 32 is divided into a pair of divided arc-shaped pieces 32a. , 32
The pair of arcuate pieces 32a and 32b are separated from each other by a larger distance toward the upper side, and the diameter (virtual diameter) gradually increases toward the upper side as a whole.

In any of the embodiments, the grooved cylinder 3 is forcibly reduced in diameter from the single state shown in FIGS. 2 to 4 and 6 to 8 and fitted into the spiral cylinder 5, whereby the grooved cylinder 3 shown in FIG. As described above, a pair of vertical grooves having the same groove width from the lower end to the upper end is formed.

The grooved tube 3 may be integrally formed with the hakama 1, or a joint fitting may be interposed between the grooved tube and the hakama 1 for high-quality appearance, or bonded to the outer circumference of the spiral tube 5. Alternatively, the metallic cover may be integrated by means such as press fitting, or metal film deposition may be performed.

[Action]

 Next, the usage and operation of the present invention will be described.

To obtain the lipstick container according to the present invention, first, the inner plate 4 is inserted into the grooved tube 3. The operation is very easy because the vertical tube 32 and the vertical groove 33 are open like a trumpet, and can be immediately dropped to the lower limit position. This is particularly remarkable in the second embodiment. After that, the vertical cylinder 32 that is widening upward may be recessed and fitted into the spiral cylinder 5.

The vertical cylinder 32 has a diameter that expands in a trumpet shape in an individual state by expanding at least one vertical groove 33 toward the upper side,
It has a good spring property. Therefore, at the moment when the spiral cylinder 5 is fitted, it is brought into close contact with the inner surface of the spiral cylinder 5 due to the force of expanding in the radial direction, and at the same time, also comes into close contact with the inner plate 4.

In use, the Hakama 1 is rotated while holding the spiral tube 5 like the conventional container of this type. At this time, in the conventional container of FIG. 10, there is a gap between the spiral tube 500 and the vertical tube 320. However, in the present invention, as described above, the entire vertical cylinder of the grooved cylinder 3 has a spring property, and as shown in FIG. 5a, the inner surface 50 of the spiral cylinder 5, especially the upper part of the spiral cylinder 5. As close as possible to the area. Therefore, when the grooved cylinder 3 rotates as the hakama 1 rotates, the inner peripheral surface of the spiral cylinder 5 and the vertical cylinder 32 are rotated.
An effective sliding resistance is created between and, and the up and down movement of the inner plate 4 is appropriately suppressed.

Therefore, despite the fact that the main part of the feeding mechanism is made of synthetic resin, a good feeling of weight can be obtained in the operation, and the inner plate 4 is inadvertently careless even if vibration is applied during transportation or carrying. Does not rise. In addition, since the present invention does not locally provide resistance, but provides rotation resistance by the spring action of the entire vertical cylinder, permanent deformation does not occur, and good rotation resistance action can be made permanent.

Further, the vertical cylinder 32 closely contacts the inner peripheral surface of the spiral cylinder 5, and
As shown in Fig. 5a, the ring projection 35 at the upper end firmly engages with the ring-shaped base portion 52 of the spiral tube 5, so that the spiral tube 5 does not move in the axial direction. Therefore, the inner plate 4 is in close contact with the vertical cylinder 32, and the vertical movement of the inner plate 4 is smooth, so that there is no play in rotation.

Further, since the upper end of the vertical cylinder 32 has the maximum diameter, there is an advantage that the cosmetic material A is unlikely to adhere even if the dish 4 inclines.

Incidentally, in order to obtain the vertical groove 33 that widens upward, an ordinary grooved tube may be deformed while being heated after being molded,
More preferably, the expanded vertical groove 33 is formed during injection molding. The method is to use a tapered core 70 as the mold 7 as shown in FIG. 9 and to form protrusions 710 and 720 on the left and right split molds 71 and 72 in conformity with the groove width of the upper opening to form the tapered core 70. The molten resin may be injected by bringing them into contact with each other.

The present invention is such that the vertical groove 33 is gradually increased from the lower end to the upper end, and the diameter of the vertical cylinder 32 is enlarged as it goes upward, and a constriction is provided only in the middle of the vertical cylinder 32 in the height direction. Not a thing. In this structure, the rotating torque is not constant, and the rotating torque is small and lightly turns in the lower and upper parts of the middle plate, and the rotating torque suddenly increases and becomes heavy in the middle.
Moreover, there is a problem that the die cannot be easily removed during molding. The present invention can avoid such a defect.

[Effect of device]

According to the present invention described above, at least one of the vertical grooves 33 of the grooved cylinder 3 is expanded toward the upper side to increase the diameter of the grooved cylinder 3 toward the upper side, thereby making the grooved cylinder 3 a spiral cylinder. By fitting with 5, the diameter is reduced and brought into close contact with the spiral cylinder 5, and rotation resistance is given by the spring force of the entire grooved cylinder, so stable rotation torque is obtained during extension / reduction for a long period of time. It is possible to eliminate the rattling of rotation. Moreover, the structure is simple, no special parts are required, and it is possible to easily install the inner plate, which is an excellent effect.
