Description

[Detailed Description of the Invention] This invention relates to a dispensing container that accommodates rod-shaped objects such as lipstick and solid glue.

When applying a stick-shaped lipstick or solid paste, the thickness of the application varies depending on the strength of the force with which the stick-like body of the lipstick is pressed against the application surface. Therefore, in order to obtain an appropriate coating thickness, it is necessary to use an appropriate pressing force depending on the hardness of the rod-shaped body.

Conventionally, the dispensing container has an outer cylinder having a spiral groove on the inner periphery, a cylindrical part rotatably supported within the outer cylinder, and a long hole extending in the axial direction formed in the peripheral wall of the cylindrical part. A cylindrical body that covers the outer periphery of a rod-shaped object such as a lipstick is formed by the guide cylinder formed by the guide tube, and a saucer having a protrusion inserted through the elongated hole and engaged with the spiral groove is provided in the cylindrical body. It is known that the proximal end of the rod-like body is directly connected to the cylinder, and the rod-like body is fed out by relative rotation between the outer cylinder and the guide cylinder. In a dispensing container configured to connect rod-shaped bodies,
During use, the force that presses the container acts directly on the rod-like object and becomes the force that presses the rod-like object against the coating surface, so the user must adjust the force with which he or she presses the container in order to obtain an appropriate coating thickness. First, if the coating surface is uneven, it is necessary to not only adjust the force pressing the container as described above, but also move the container so that the rod follows the unevenness of the coating surface, in order to obtain a uniform thickness. It was difficult to apply the product by hand, and improvements were desired in terms of operability, etc. Furthermore, in the container configured as described above, there was a risk that the internal rod-like body would break if a large impact force was applied in the forward/backward direction of the rod-like body while carrying the container.

This idea was made in consideration of the above-mentioned circumstances, and it is possible to press a rod-shaped object such as lipstick against the application surface with the optimum strength without having to adjust the force with which the container is pressed, thereby eliminating unevenness on the application surface. The object of the present invention is to provide a dispensing container that can be easily and uniformly coated even in such cases, and that reduces the risk of damage due to impact forces received during carrying. Its characteristics are:
The inner tray, which fixes the base end of the rod-shaped body, is elastically supported by a tray that moves back and forth within the cylinder.

Embodiments of the present invention will be described below with reference to the drawings.

1 and 2 show a first embodiment in which the lipstick container is used. In these figures, 1 indicates a cylinder, 2 a saucer, and 3 a lipstick (rod-shaped body).

The cylinder 1 includes an outer cylinder 4 having a spiral groove 4a on the inner periphery, and a guide cylinder 5 having a bottomed cylinder shape and having a cylinder part 5a fitted into the outer cylinder 4 at the top thereof. Consisting of This guide cylinder 5 has a long hole 5b formed in the circumferential wall of the cylinder part 5a along the axial direction of the cylinder, and a protrusion 5c formed at the upper end of the cylinder part 5a. It is rotatably supported by the outer cylinder 4 by fitting into a groove 4b formed on the inner periphery.

The receiving tray 2 includes a cylindrical main body 2a having an outer diameter slightly smaller than the inner diameter of the guide cylinder 5 and housed in the guide cylinder 5, and a cylindrical main body 2a that protrudes from the outer periphery of the main body 2a and passes through the elongated hole 5b. Along with the spiral groove 4a
The main body 2a is provided with a protrusion 2b that fits into the main body 2a, and a protrusion 2c provided around the inner periphery of the main body 2a, and moves back and forth within the guide cylinder 5 by relative rotation between the guide cylinder 5 and the outer cylinder 4.

The lipstick 3 has an inner plate 6 fixed to its lower end.
It is elastically supported by the tray 2 by a spring 7 interposed between the inner tray 6 and the tray 2.

The inner tray 6 has a small diameter portion 6a that has an outer diameter slightly smaller than the inner diameter of the tray 2 and is inserted into the tray 2;
A step 6b is formed at the upper end of the small diameter part 6a, and a large diameter part 6c fixes the lower end of the lipstick 3. On the outer periphery of the small diameter part 6a, there is an engagement that engages with the protrusion 2c in the saucer 2. A stop groove 6d is formed.
The width dimension W of this locking groove 6d is set larger than the width dimension W of the protrusion 2c, and due to the dimensional difference between these W and w, the inner tray 6 is larger than the width dimension W of the protrusion 2c. They are connected so that they can move an appropriate amount in the forward and backward directions.

The spring 7 has an inner diameter that is a small diameter portion 6 of the medium plate 6.
With a coil spring set slightly larger than a,
As shown in FIG. 2, when the small diameter portion 6a of the inner plate 6 is fitted into the receiving plate 2, it is inserted between the inner plate 6 and the receiving plate 2 so as to loosely fit into the small diameter portion 6a, and the upper end (in Fig. 2) is brought into contact with the step 6b of the inner tray 6, and the lower end is brought into contact with the upper end surface of the receiving tray 2, so that the inner tray 6
The receiving tray 2 is urged upwardly (in the advancing direction of the receiving tray 2).

With such a configuration, when the cylindrical body 1 is held and the tip of the lipstick 3 is pressed against the application surface such as the lips,
The spring 7 works until the inner plate 6 sinks to the maximum extent, and the elastic force of the spring 7 becomes the pressing force for the lipstick 3. Therefore, by setting the elastic force of the spring 7 in advance to a strength that matches the hardness of the lipstick 3, etc., the lipstick 3 can be pressed with the optimum strength without having to adjust the force with which the cylinder 1 is pressed. I can do it. Furthermore, if there are irregularities on the application surface, the inner plate 6 moves back and forth within the cylindrical body 1 due to the elastic deformation of the spring 7, and the lipstick 3 follows the irregularities while keeping the pressing force approximately constant. Uniform coating can be easily performed even on uneven coating surfaces, improving operability and usability. Furthermore, even if a large impact force is applied to the cylinder body 1 in the forward and backward directions of the lipstick 3 when carrying it, etc., the impact force is buffered by the spring 7, so the risk of the lipstick 3 breaking is reduced. .

In the above-mentioned embodiment, as shown in FIG. 2, in order to facilitate assembly of the inner tray 6 and the receiving tray 2, the lower end of the small diameter portion 6a and the upper end of the protrusion 2c are provided with inclined surfaces. Although the inclined surfaces 6e and 2d are formed, only one of these inclined surfaces 6e and 2d may be formed, or one may be formed into a curved surface as shown in FIG. Further, in the embodiment described above, the spring 7 was formed so as to fit onto the small diameter portion 6a of the inner plate 6, but as in the second embodiment shown in FIGS. The spring 7 may be formed into a cylindrical shape with a bottom, and the upper end of the spring 7 may be fixed to the bottom of the inner tray 6, and the lower end thereof may be formed to abut against the inner bottom of the receiving tray 2. Furthermore, in the above embodiment,
The cylinder body 1 is composed of an outer cylinder 4 and a guide cylinder 5, and the mechanism is such that the saucer 2 is moved forward and backward by the spiral groove 4a and the elongated hole 5b formed in each of them, but the mechanism for advancing and retracting the tray 2 is limited to this. Instead, a mechanism may be used in which, for example, a plurality of claws are provided on the inner periphery of the cylindrical body 1 and are arranged in the advancing and retracting direction, and grooves that engage with the claws are provided on the outer periphery of the receiving tray 2. Moreover, the rod-shaped body serving as the content is not limited to the above-mentioned lipstick.

As explained above, the dispensing container of the present invention is configured such that the inner plate, which fixes the base end of the rod-shaped body such as lipstick housed in the cylindrical body, is elastically supported by a spring on the receiving plate which moves back and forth within the cylindrical body, and when the cylindrical body is pressed to press the tip of the rod-shaped body against the application surface, the spring elastically deforms until the inner plate 6 sinks to its maximum extent, and this elastic force becomes the pressing force of the rod-shaped body. Therefore, if the elastic force of the spring is set in advance to a strength that matches the hardness of the rod-shaped body, the user can press the rod-shaped body with optimal strength without adjusting the operating force of the hand. Also, if the application surface is uneven, the inner plate moves back and forth relative to the receiving plate due to the elastic deformation of the spring, and the rod-shaped body follows the unevenness while maintaining a substantially constant pressing force, so that it is easy to apply evenly to the uneven application surface, improving operability and usability. Furthermore, even if a large impact force is applied to the cylindrical body in the forward or backward direction of the rod-shaped body when it is carried, the impact force is buffered by the spring, reducing the risk of the rod-shaped body breaking.
