Description

[Detailed Description of the Invention] The present invention relates to a lipstick container, and particularly to a lipstick container having a lid that can be opened and closed with one touch without separating from the container body.

2. Description of the Related Art Conventional lipstick containers have a lid that can be fitted onto and removed from the outside of a container body, and for example, one having a structure as shown in FIG. 7 is known. First, to briefly explain this, FIG. 7 is a vertical cross-sectional view of a conventional lipstick container, in which a lipstick 23 is supported on an inner cylinder 21 having vertical grooves 21a at symmetrical positions on both sides, and the lipstick 23 is supported by the vertical grooves 21a. A lipstick holder 22 is provided with a protrusion 22a that is slidably fitted therein, and is fitted onto the outer peripheral surface of the inner cylinder 21, so that the tip of the protrusion 22a of the lipstick holder 22 is engaged. An outer cylinder 24 having a matching spiral groove 24a is rotatably mounted thereon, and a lid 25, which is a bottomed cylinder, is fitted onto the outer side of the outer cylinder 24 so as to engage with the inner cylinder 21. .

Therefore, in this case, when using the lid body 2, first
5 from the inner cylinder 21 and remove it by pulling it out. Hold the lid 25 by hand or place it somewhere nearby, such as on a table, and then remove the inner cylinder 21 and the outer cylinder 24.
2 with the fingers of both hands and rotate them in opposite directions to form the protrusion 2 due to the relationship between the vertical groove 21a and the spiral groove 24a.
By guiding the lipstick 2a upward, the lipstick 23 is appropriately projected and used. After use, operate in the opposite direction to retract the lipstick 23, take the removed lid body 25 with your finger again, fit it into the inner and outer cylinder body parts, and close the inner cylinder 21.
to the storage state.

In this way, in conventional lipstick containers, the lid is separate from the main body, so it is troublesome to attach and detach it during use, and there is a risk of powder loss.
Even if you put on makeup by holding the removed lid between your little finger and middle finger, there are drawbacks such as the operation being cumbersome, and on the other hand, the cylindrical body is triple-layered, so it is a waste of material. However, it also had the disadvantage that it was not desirable in terms of resource conservation.

The present invention was developed in view of the above-mentioned drawbacks, and the lid can be opened and closed only at the lipstick insertion/extraction portion, and the opening/closing of the lid can be done with a single touch in conjunction with the series of operations for loading and unloading lipstick from the cylindrical body. The purpose of the present invention is to provide a new type of lipstick container with an extremely simple structure, the gist of which is to have an inner and outer cylinder that are coaxially fitted and that are fixed in the axial direction and rotate in opposite directions, A spiral groove is formed on the inner surface of the outer cylinder,
A lipstick that has a groove opening across the top and bottom of an inner cylinder, a horizontal groove at least at its lower end, and a lipstick holder that has a projection formed in the inner cylinder that movably engages with the spiral groove through the groove. In the container, a pivot shaft is provided protruding from the back surface of the lid body that closes the upper end surfaces of the inner and outer cylinders, and a grooved cam is formed in a direction intersecting the radial direction adjacent to the pivot shaft, and the grooved cam has at least one end. is formed to be open on the outer periphery of the lid body, and the pivot shaft is rotatably fitted to the upper end of one of the inner and outer cylinders, and an engaging projection protruding from the upper end of the other inner and outer cylinder is connected to the grooved cam. The opening/closing lid body is movably engaged with the lid body. In this case, it is more preferable that the length of the horizontal groove of the inner cylinder is equal to or close to the rotational distance of the inner cylinder required for the lid to rotate approximately 180 degrees. . The present invention will be described in detail below based on the illustrated embodiments.

FIG. 1 is a longitudinal sectional view of an example of a container according to the present invention;
Figure 2 is an exploded perspective view of the main parts of the embodiment in Figure 1;
The figure is an enlarged cross-sectional view of the pivot part of the lid body, and Figure 4 is inside.
1 is a plan view showing the opening/closing operation state of the lid body relative to the outer cylinder, 1 is an inner cylinder, one end side forms a base part 1b having a bottom part 1a, and the other end side forms a lipstick entrance/exit port 1c constituting an open end part. Two guiding vertical grooves 1d and 1e are symmetrically formed on the side, and one groove 1d reaches to the upper end to form an open groove, into which a lipstick holder 2, which will be described later, can be incorporated. In addition, when assembling the outer cylinder 4, the outer diameter can be narrowed, and each groove 1
The upper and lower ends of d and 1e are opposite to each other and 1/1/2 in the circumferential direction.
Horizontal grooves 1da and 1ea for about six turns are formed continuously with vertical grooves 1d and 1e. Also, on the outer peripheral surface of the upper end,
An engaging part 1f that fits and engages with a step part 4b of the outer cylinder 4, which will be described later, is formed in a protruding manner, and a portion of the lower outer wall surface of the engaging part 1f is removed, and a hole is formed that penetrates in the vertical direction at that position. 1g is formed (Figure 3). Furthermore, a lid body 5 (described later) is provided on a part of the outer periphery of the engaging portion 1f.
A notch 1h is formed into which the projection 5c fits during rotation. 2 is a lipstick holder that supports lipstick 3;
It fits into the inner cylinder 1, and has grooves 1d and 1da and grooves 1e and 1 that protrude symmetrically and horizontally on both outer surfaces.
Round bar-shaped protrusions 2a are integrally formed to fit through each ea. Reference numeral 4 denotes an outer cylinder, on the inner surface of which the end of the projection 2a of the lipstick holder 2 is engaged and guided.
A spiral groove 4a is formed, the lower end of which rotatably engages with the upper end of the base 1b of the inner cylinder 1,
A step portion 4b that fits and engages with the engaging portion 1f of the inner cylinder 1 is formed at the upper end, and an engaging protrusion 4 as an engaging portion that engages with a grooved cam 5b, which will be described later, is formed on the upper edge.
c and a notch 4d adjacent thereto. Reference numeral 5 denotes a lid body, and the peripheral part of the back surface is formed to be slightly thinner than the center part, and a part of the periphery of the back surface is rotatably fitted into the hole 1g of the inner cylinder and has a stopper to prevent it from coming off. Therefore, a pivot shaft 5a whose tip part has a partially enlarged diameter is integrally formed, and a grooved cam 5b as a cam part inclined in the radial direction is formed from the shaft 5a part. A protrusion 5c that can fit into the notch 4d of the outer cylinder 4 is integrally formed on the peripheral edge of the open end of the grooved cam 5b adjacent in the direction of the axis 5a.

With the container of the present invention configured in this way, the first and second
From the state shown in the figure, hold the base 1b of the inner cylinder 1 with one hand,
When holding the outer tube 4 with the other hand and rotating the outer tube 4 as shown by arrows A and B in FIG.
Since the lipstick 3 is engaged with the groove cam 5b of the lid body 5, the lipstick 3 does not rise because the outer cylinder 4
Since the projections 4c are engaged, the lid body 5 is moved as the shaft 5a pivoted to the inner cylinder 1 moves leftward from the state a to the state b, as shown in FIG. It operates to rotate to the right with respect to the axis 5a. When the lid body 5 is rotated approximately 90 degrees, the protrusion 5c comes to the outer cylinder peripheral surface position, but since the notch 4d is formed on the peripheral surface portion on the trajectory of the projection 5c, the projection 5c is placed on the right side of the lid body 5 as it is. Can be rotated. Due to the subsequent mutual rotation of the inner and outer cylinders 1 and 4, the lid body 5 continues to rotate to the right, but at the stage when the protrusion 5c accompanying this movement reaches the peripheral surface of the inner cylinder 1, it just touches the groove-like groove of the inner cylinder. Notches 1h are provided opposite each other, and the protrusion 5c fits into the notches. Then, when the inner and outer cylinders 1 and 4 continue to mutually rotate, the protrusion 5c fits into the groove of the notch 1h, and at the same time, the engagement protrusion 4c comes out from the open end of the grooved cam 5b of the lid body 5. The lid body 5 rotates approximately 180 degrees with respect to the shaft 5a, stops its rotation, and locks the inner cylinder 1 with the projection 5c.
They begin to move as one (Figure 4C).
At this initial stage of locking, the protrusion 2a of the lipstick holder 2 moves from the horizontal groove 1ea of the inner cylinder 1 to the vertical grooves 1d, 1e, whereby the lipstick 3 rises and comes to protrude from the opening 1c. Such horizontal groove 1ea is the cover body 5
so as to synchronize with the movement of the to the locked state.
The shape and length of the grooved cam 5b may be set together with the grooved cam 5b. When the lipstick 3 is projected by the subsequent mutual rotation of the inner and outer cylinders 1 and 4, the lid body 5
They move together as one while being locked in place (d in the same figure). By the way, it is better to cut out the part of the lid 5 that protrudes into the inner cylinder 1 in the fully open position, that is, the shaded part in FIG. Although it is preferable, a required gap may be created between the inner diameter of the inner tube 1 and the base diameter of the lipstick 3, and there may be no cutout portion. Further, it is convenient when applying makeup if a mirror is provided on the surface of the lid body 5.

To close the lid 5 from the open state,
The inner and outer cylinders 1 and 4 may be rotated in opposite directions of arrows A and B, contrary to the above description. With this, the lid body 5
From the state shown in FIG.
Since it comes out from h and becomes free, the closing operation is performed by the engagement between the protrusion 4c and the grooved cam 5b. This closing operation is performed synchronously after the lipstick 3 is stored in the cylinder. Furthermore, when the lid 5 is closed, the thin wall around the back surface of the lid 5 engages with the upper edge of the outer cylinder 4, so the thick wall at the center fits into the peripheral edge, and the lid closes. The body 5 will be held semi-fixed. When the container is opened from the closed state, the container is made of synthetic resin, aluminum, or other metal, so the pivot portion or other parts have some elasticity, so they do not deform elastically. However, the thick center portion of the lid 5 easily rotates over the upper edge of the outer cylinder 4.

FIG. 5 is an exploded perspective view of essential parts of another embodiment of the container of the present invention, and FIG. 6 is a plan view showing the opening/closing operation state of the lid of the same embodiment. In this case, the structure of the lower part of the container is This embodiment is the same as the first embodiment, and only the upper lid-related components are different, so a description of the similar parts will be omitted. Reference numeral 11 denotes an inner cylinder, and numeral 14 denotes an outer cylinder, which are fitted to each other in the same manner as in the above-mentioned embodiment, and a lid 15 is disposed at the top. This inner cylinder 11 is also formed with vertical grooves 11d and 11e, followed by horizontal grooves 11da and 11ea, respectively, and an engaging portion 11f that fits and engages with a stepped portion of the outer cylinder 14, which will be described later, is formed on the outer circumferential surface of the upper end. A part of the lower outer wall surface is removed, and a hole 11g penetrating in the vertical direction is formed at that position. A step portion 14b that fits and engages with the engaging portion 11f of the inner tube 11 is formed on the upper part of the outer cylinder 14, and a fitting protrusion 14e that protrudes slightly from the inner wall side of the upper edge is formed on the periphery. A part of the upper edge forms an axial notch 14d, and a part of the upper edge has an engaging part that engages with a groove cam 15b of the lid 15, which will be described later. An engaging protrusion 14c is formed. 14a is a guide groove for a lipstick holder (not shown).
Reference numeral 15 denotes a lid body, and a part of the peripheral part of the back side of the lid body has a partial circle inward that fits between the engagement protrusions 14c from the left end in FIG. 5 of the notch 14d of the outer cylinder 14 when the lid is closed. A first protrusion 15c constituting a protruding cam portion and a pivot shaft 15a protruding downward from a portion thereof and fitting into the hole 11g of the inner cylinder 11 are each integrally formed. 15d similarly fits between the engagement protrusion 14c from the right end of the notch 14d,
A first cam portion, which similarly constitutes a cam portion, extends inward approximately along the first projection 15c to a position corresponding to the intermediate portion thereof, and whose tip portion is bent toward the first projection 15c to protrude integrally. There are two protrusions, and as a result, a groove cam 15b serving as a cam portion with which the protrusion 14c engages is formed between the protrusions 15c and 15d. Also, along the periphery of the back surface of the lid body 15, the outer cylinder 14
A recessed groove (not shown) is formed which fits into the fitting protrusion 14e.

Therefore, in this case as well, if the inner and outer cylinders 11 and 14 are rotated in the directions of arrows C and D as in the above embodiment, the shaft 15a will first move to the position shown in FIG. By moving leftward from the state a to the state b, the protrusion 14C becomes the first protrusion 15C.
While pressing , move inside the grooved cam 15b and remove the lid 15.
Rotate to the right. After sequential rotation, the lid body 15 assumes the fully open position in the state shown in FIG. , placed in a semi-fixed state. Therefore, by the subsequent rotation, the lid body 15
is maintained in that position while the lipstick is allowed to protrude as appropriate. When closing the lid after use, after storing the lipstick completely, rotate the tubes 11 and 14 in the opposite direction to the above and engage the protrusion 14C in the groove cam 15b again. 14C is the second protrusion 15d
The side surface of the lid body 15 is pressed toward the open end side from the above-mentioned bent portion, and the lid body 15 is rotated to the left to return to the state shown in Fig. a, and the lid is closed. At this time, the outer surface of the second projection 15d comes into contact with the end surface of the notch portion 14d and stops, and at this time, the annular groove (not shown) of the lid body 15 fits into the projection 14e of the outer cylinder 14, so that the lid body 15 is stably held. That will happen. In this case as well, the lid body 15 is as shown in FIG. 6b.
It is advisable to cut off the part that protrudes inward from the inner cylinder 11 at the fully open position.

Note that the present invention is not limited to the above-mentioned embodiments; for example, by reversing the cam mechanism as appropriate,
It is also possible to open and close the lid body by rotating the inner and outer cylinders in the opposite direction to the above-mentioned embodiment. It is also possible to create a gap between the pivot shaft and the locking part at the tip of the pivot shaft to protrude into the gap, and to pivot the engagement part, depending on the shape and size of each part, and the cam part. Of course, the inclination of the cam surface with respect to the line of action can also be set as appropriate.

As described above, according to the container of the present invention, the lid body can be opened and closed with a single touch in conjunction with a series of rotating operations associated with normal lipstick loading and unloading operations without separating from the container body. It can be used smoothly without any resistance, and the lid does not get in the way of use. In addition, the mechanism is extremely simple and parts can be omitted, which is advantageous in terms of cost. It has the following characteristics.
