Description

[Detailed Description of the Invention] The present invention relates to a container for dispensing stick-shaped objects such as lipstick.

Traditionally, lipstick dispensing containers have a vertical groove in the inner tube, a spiral groove in the outer tube that fits on the outer periphery of the inner tube, and a spiral groove in both grooves to allow the outer circumferential surface of the container to hold the lipstick, etc. A device is used in which the receiver cylinder is moved up and down by engaging a guide protrusion protruding from the inner cylinder and rotating the outer cylinder relative to each other.

However, in this type of container, when the lipstick is transported while stored in the container, or when the lipstick is carried around by the user, the lipstick is naturally drawn out due to vibrations and the tip of the lipstick comes into contact with the cap etc. and becomes deformed. Otherwise, the inconvenience of breakage occurred.

The present invention was devised in order to solve the above-mentioned drawbacks, and aims to provide a container that can prevent lipstick from spontaneously coming out during transportation or carrying.

Next, embodiments of the present invention will be described in detail with reference to the drawings.

In FIGS. 1 and 2, the container for dispensing lipstick, etc., has an inner tube 1, a receiving tube 2 for lipstick, etc. fitted inside the inner tube so as to be slidable in the vertical direction, as in the case of known containers. It consists of an outer cylinder 3 rotatably fitted to the outer periphery of a cylinder 1, both of which are made of synthetic resin.

The inner cylinder 1 is formed into an elongated cylindrical shape as a whole, and has a fitting cylinder part 5.
and a grip part 4 of a slightly larger diameter connected to the lower part of the grip part 4.

A pair of vertical grooves 6, 6 facing each other is bored in the peripheral wall of the fitting cylinder 5, and each vertical groove 6 has horizontal grooves 12, 14 extending in opposite directions at both the upper and lower ends. has been done.

Further, a projecting edge 9 is formed at the upper end of the fitting cylindrical portion 5, and a cutout portion 12' is continuous from the upper end of the negative vertical groove 6 and opens at the projecting edge 9.

The lipstick receiving tube 2 has a relatively short and small cylindrical shape with a bottom, and has a pair of guide protrusions 11, 11 protruding from its outer peripheral surface in the radial direction.

The receiving cylinder 2 is inserted into the inner cylinder 1 by passing one of the guide projections 11.11 through the cutout 12', and the guide projection 1 is inserted into the inner cylinder 1.
1.11 is inserted into the vertical grooves 6, 6 to hold the receiving cylinder 2 in the inner cylinder 1 so as to be able to freely slide vertically.

The outer tube 3 is formed into a cylindrical shape that is slightly shorter than the fitting tube portion 5 of the inner tube 1, and a pair of spiral grooves 7, 7 are formed on the inner circumferential surface of the outer tube 3, facing each other.

These spiral grooves 7, 7 have the same spiral thread 18 times in the circumferential direction.
It is displaced by 0°.

Therefore, when the outer cylinder 3 is fitted onto the outer periphery of the inner cylinder 1 that holds the receiving cylinder 2, the guide protrusion 11 that passes through the vertical grooves 6, 6 of the inner cylinder 1c
．． 11 are engaged with the spiral grooves 7, 7 of the outer cylinder 3, respectively.

By relatively rotating the inner tube 1 and the outer tube 3 in this manner, the receiving tube 2 that holds the lipstick or the like 10 can be moved up and down.

Note that this outer cylinder 3 is held between an upward step part 8 formed between the fitting cylinder part 5 and the gripper 4, and a ridge 9 at the upper end of the fitting cylinder part 5, and is separated from the inner cylinder 1. is prevented from coming off.

Further, since the upper horizontal groove 12 is provided in the vertical groove 6, by engaging the guide protrusion 11 of the receiving tube 2 with the upper horizontal groove 12, the receiving tube 2 can be moved into the inner tube 1.
It is easy to attach the lipstick because it can be held once at the upper end, and when the lipstick is fed out and used, the outer cylinder 3 does not rotate, but the lipstick can be held in the extended state, so that the lipstick can be held inside the inner cylinder 1. It is possible to prevent immersion in

Further, the lower lateral groove 14 prevents the lipstick from being fed out naturally unless the outer cylinder 3 rotates.

Among the above-mentioned known containers, the features of this invention are as follows:
A slope 16 is formed at the front edge of the lower part of the vertical groove 6 in the rotational direction of feeding out the outer cylinder 3, so that even if a force to rotate the outer cylinder 3 is applied, lipstick etc. The problem lies in trying to prevent spontaneous release.

To explain this point in detail, the lower end of the vertical groove 6 is connected to the horizontal groove 14.
It is also slightly expanded in the opposite direction to the direction in which it extends, making it wider.

and a side edge 15 of the vertical groove 6 opposite to the direction in which the horizontal groove 14 extends.
Above the upper edge 19 of the lateral groove 14, the lateral groove 14 has a slope 16 that slopes downward and outward.

Thus, the outer cylinder 3 is provided so that the spiral groove 7 thereof is inclined in the same direction as the slope 16.

The spiral groove 7 of the outer cylinder 3 is arranged diagonally from the upper right to the lower left in FIG. Protrusion 11 with vertical groove 6
Push up upwards along the line to feed out the receiving tube 2 and the stick-like object such as lipstick stored therein.

Therefore, the slope 16 provided in the vertical groove 6 of the inner cylinder 1 is provided on the front side edge 15 of the outer cylinder 3 in the feeding rotation direction A.

For this reason, the lower side edge 7' of the spiral groove 7 and the slope 16 are arranged to face each other.

An engaging protrusion 18 is formed on the other side edge 17 of the vertical groove 6 slightly above the slope 16, and when the guide protrusion 11 of the receiving tube 2 passes, this engaging protrusion 18 and this It is once clamped and engaged between the opposing side end surfaces.

In the above-described dispensing container, when a force is applied to rotate the outer cylinder 3 during transportation or carrying, the guide protrusion 11 of the receiving cylinder 2 is pressed diagonally upward by the bottom surface of the spiral groove 7 and the upper edge of the horizontal groove 14 Move while touching 19.

When the guide protrusion 11 moves from the horizontal groove 14 into the vertical groove 6, the guide protrusion 11 moves obliquely upward and substantially perpendicular to the spiral groove.

Next, the outer cylinder 3 comes into contact with the front side edge 15 in the feeding rotation direction A, and thereafter moves upward while contacting this side edge 15. However, in the container of this invention, the outer cylinder 3 Since the longitudinal groove side edge 15 in front of the vertical groove side edge 15 in the feeding rotation direction A has a slope 16 facing diagonally downward, the guide protrusion 11 of the receiving cylinder 2 is inserted into the vertical groove 6 after exiting the horizontal groove 114 as described above. The lipstick moves diagonally upward and comes into contact with the slope 16, and is once clamped and held between the lower side edge 7' of the spiral groove 7, thereby preventing the lipstick etc. from coming out naturally.

Even if a large rotational force is exerted on the outer cylinder 3 and the engagement is released, the guide protrusion 11 can be held in place again since the engagement protrusion 18 is provided further upward. will be maintained.

In this way, natural feeding of the lipstick can be prevented, but when feeding the lipstick during use, there is a feeling when the guide protrusion 11 of the receiving tube 2 is in contact with the slope 16, and from this state, it is necessary to apply further force. The guide protrusion 11 is pressed and moved upward, and is further extended beyond the engagement protrusion 18.

Since the slope 16 is inclined in the same direction as the spiral groove 7 of the outer cylinder 3, the guide protrusion 11 of the receiver 2 is once sandwiched between the slope 16 which slopes in the same direction and the lower side edge 7' of the spiral groove 7. After the guide protrusion 11 is inserted, the guide protrusion 11 can easily overcome the slope 16 by further rotating the outer cylinder.

It is preferable to form the slope angle α to be smaller than the slope angle β of the spiral groove 7 because less force is required to move the guide protrusion 11 over the slope 16.

FIG. 3 shows another embodiment of the present invention, in which a recess 21 is formed slightly above the lower end of the longitudinal groove side edge 15 in front of the outer cylinder 3 in the rotation direction A, and the upper end of the recess 21 is It has a slope 16 facing diagonally downward.

As described above, the dispensing container for lipstick or the like according to the present invention is constructed as follows:
5 is characterized by forming a slope 16 that extends downwardly into the inner side of the container, so that it can be used when transporting lipstick etc. in a container or when being carried by a user and subjected to vibrations. Since the guide protrusion 11 of the lipstick holder 2 is held in contact with the slope 16, it is possible to prevent the tip from being deformed or broken due to natural feeding of the lipstick or the like.

Further, since the engaging protrusion 18 is formed above the slope 16, the guide protrusion 11 can be engaged again at this portion, and natural feeding can be prevented even more reliably.

Furthermore, since the slope 16 and the spiral groove 7 provided on the outer cylinder are inclined in the same direction, the guide protrusion 11 of the receiving cylinder 2 is once inserted between the slope 16 and the lower side edge 7' of the spiral groove 7. This is preferable because it can be easily removed upward after being applied, and the lipstick can be dispensed with a light touch.
