Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a container with an automatic opening / closing lid, and more specifically, a rotation axis is orthogonal to a longitudinal axis of the container when the lid is opened and closed with respect to the container body. The present invention relates to a container with an automatic opening / closing lid that is movable in the radial direction and can be easily attached to the container body.

(Prior Art) Conventionally, as a container with an automatic opening / closing lid of this type,
It is known to be applied to a stick-shaped cosmetic product feeding container described in Japanese Utility Model Laid-Open No. 58-88914 shown in (a) and (b).

In this conventional stick-shaped cosmetic product dispensing container, a rotary cylinder 2 is fitted on the outer peripheral surface of a main cylinder 1 so that it can be moved in the axial direction by rotation. A tail pipe 3 is fitted and fixed to the outer peripheral surface of the rear end of the main cylinder 1, and a saucer 4 holding a stick-shaped cosmetic material 5 advances and retreats on the axis line. It is configured to be extended or extended.

Further, an opening / closing lid 6 is attached to the tip end of the rotary cylinder 2 so as to be able to open freely, and is configured to protect the cosmetic material 5 stored in the main cylinder 1.

Due to such a conventional structure of the container of this type, when the rotary cylinder 2 is rotated in a predetermined direction, the rotary cylinder 2 becomes the main cylinder 1.
In contrast, the rear end of the main cylinder 1 is accommodated in the gap between the main cylinder 1 and the tail pipe 3, and the lower end of the rotary cylinder 2 exposes the leading edge of the main cylinder 1 to project upward. That is, the leading edge of the main cylinder 1 comes into contact with the opening / closing lid 5 from the inside and pushes it up, whereby the opening / closing lid 5 opens. Further, when the rotary cylinder 2 is rotated, the saucer 4 moves forward in the main cylinder 1 and the stick-shaped cosmetic material 5 is delivered.

(Problems to be solved by the invention) By the way, in this payout container, the hinge portion 6a, which is the mounting portion of the opening / closing lid 6 at the tip edge of the rotary cylinder 2, does not hinder the movement of the main cylinder 1 and the saucer 4. In order to do so, the rotary cylinder 2 is provided at a position projecting radially outward from the tip edge of the rotary cylinder 2.

However, if the hinge portion 6a is provided at the position projecting radially outward from the tip end edge of the rotary cylinder 2 in this way, the appearance is very poor and it is not suitable as a cosmetic container, which reduces the consumer's willingness to purchase. The result was sometimes. Also,
Since such a hinge portion 6a is configured by providing a hinge support shaft and a support shaft hole, the number of parts increases, which is disadvantageous in terms of manufacturing cost and assembly cost.

The purpose of the present invention is to solve the above-mentioned conventional problems, focusing on improving the appearance of the container, and further improving the automatic cost by reducing the number of parts and overall cost reduction. An object is to provide a container with an opening / closing lid.

(Means for Solving the Problem) The present invention is a container with an automatic opening / closing lid, and is configured as follows in order to achieve the above-mentioned technical problems. That is, the container with an automatic opening / closing lid of the present invention has a container body with an open tip, a lid body attached to the tip of the container body to open and close the open end, and holds solid contents inside. A sliding cylinder slidably disposed inside the container body so that the container body can slide in and out through the tip open end, and a torsion coil spring for urging the lid body to a closed state at one end, The container body is fixed so that the coil portion of the torsion coil spring, which is fixed to the lid body and has the other end serving as the hinge portion of the lid body, is positioned on an imaginary central axis in the tip opening surface area of the container body. When the lid body is opened and closed by simply attaching the other end of the torsion coil spring attached to the lid body to the tip end portion of the container body, Characterized in that it is movably supported relative to the container body in a direction orthogonal to the coil portion in the longitudinal axis of the container body.

(Operation) According to the container with an automatic opening / closing lid of the present invention, when the sliding cylinder holding the solid contents is operated so as to protrude from the tip open end of the container body, the tip end of the sliding cylinder becomes the container body. The tip open end of is brought into contact with the lid body closed by the spring force of the torsion coil spring and pushed up. At this time, the lid is supported on the container body only by the torsion coil spring, and the opening / closing rotation of the lid is performed by the coil portion of the torsion coil spring.

Therefore, the lid pushed up by the tip of the sliding cylinder is rotated by the coil for opening and the springiness of the end of the torsion coil spring attached to the tip of the container body pushes the lid up. Accordingly, the container body is free to move in the direction orthogonal to the longitudinal axis.

As a result, when the sliding cylinder projects from the open end of the container body, even if the hinge part for rotating the lid, that is, the coil part of the torsion coil spring is positioned in the open area of the container body front end, It can be opened so that it can project from the open end of the body.

The end of the torsion coil spring, which is attached to the container body, provides an urging force by its spring property so that the coil portion returns to its original position while the lid body is open, and the coil portion itself also moves toward the lid body in the closing direction. Since the sliding urging force is applied, the sliding cylinder immediately returns to the original closed state when it is housed in the container body.

In this way, when the sliding cylinder moves in and out from the tip end opening end of the container body, the lid body moves together with the hinge part in the radial direction from the container body tip end opening surface area in conjunction with the movement of the sliding cylinder to open and close. Therefore, even if the hinge portion of the lid body is positioned within the opening surface area of the front end of the container body to improve the appearance during closing, it does not hinder its use.

(Example) Hereinafter, the container with an automatic opening / closing lid of the present invention will be described in more detail with reference to an embodiment shown in the drawings. FIG. 1 and FIG. 2 show an example in which the container with an automatic opening / closing lid of the present invention is applied to a cosmetics dispensing container. This cosmetic feeding container includes an outer casing 10, which is a front portion 10A and a rear portion 1.
It is composed of two independent cylinders of 0B.

The tip portions 10A and 10B are flush with each other with the same outer diameter, and are relatively rotatable on a coaxial line through an inner guide tube 11. That is, one rear exterior cylinder that is a bottomed cylinder
10B is fitted and fixed to the outer peripheral surface of the guide cylinder 11, and the other front portion exterior cylinder 1 with the center hakama 11a of the guide cylinder 11 as a boundary.
Similarly, 0A is connected around the outer peripheral surface of the guide cylinder 11 by a ring 12 and can rotate. In addition, the guide tube 11
A vertical slit 11b is formed in the base member 11 so as to extend in the longitudinal direction from the base end portion.

Further, a mounting tube 15 is fitted to the tip open end of the front exterior tube 10A, and a lid 13 is attached to the mounting tube 15 so that the lid 13 can be opened freely. The lid 13 is attached by a pair of torsion coil springs 14 to the front portion. The outer cylinder 10A is biased in a direction to close the open end of the tip. The pair of torsion coil springs 14 position the coil portion 14c on the virtual central axis immediately below the inside of the lid body 13 so as not to project outside from the area of the open end of the front exterior cylinder 10A during the closing of the lid body 13. As described above, one end 14a is embedded and supported on the lid 13 side, and the other end 14b is connected to the connecting line 1
It is connected by 4d. End 14b connected by connecting line 14d
2 is inserted into a U-shaped mounting recess 15a formed on the outer peripheral surface of the distal end portion of the mounting cylinder 15 as shown in FIG. 2B, and is covered and supported by the front exterior cylinder 10A.

Therefore, it is not necessary to use a conventional spindle pin to support the torsion coil spring 14. This end portion 14 (b) itself has a spring property, and biases the coil portion 14c of the torsion coil spring 14 inward in the radial direction of the front exterior cylinder 10A, and the rear end of the closed lid 13 is first. It does not project outward from the surface of the exterior / exterior cylinder 10A and is flush with the surface. When the lid 13 is opened, the other end 14b of the torsion coil spring 14 is elastically bent, and the coil portion 14c is displaced outward and escapes.

On the other hand, a spiral cylinder 16 is fitted on the inner peripheral surface of the guide cylinder 11 so as to be slidable in the axial direction and rotatable in the circumferential direction. The spiral cylinder 16 is a sliding cylinder that comes in and out from the front end open end of the front exterior cylinder 10A that constitutes the container body. This spiral tube 16
A vertical guide groove 16f is formed on the outer peripheral surface of the spiral cylinder 16 from the tip to the middle portion.
A guide protrusion 16g protruding from the inner surface of 15 is inserted.
As a result, the spiral cylinder 16 is attached to the mounting cylinder 15, that is, the front exterior cylinder 10A.
And the inside of the mounting cylinder 15, that is, the inside of the front exterior cylinder 10A, are slidable in the axial direction.

An outer spiral groove 16A is formed on the outer peripheral surface of the spiral cylinder 16. As is apparent from FIG. 2, the shape of the external spiral groove 16A is such that, starting from the top end portion 16a of the tip end of the spiral cylinder 16, it starts obliquely and descends to the base end portion of the spiral cylinder 16. There is. An external horizontal groove 16C is formed following the end of the external spiral groove 16A so as to have a length that makes one round in the circumferential direction on the outer peripheral surface of the base end portion of the spiral cylinder 16.

A first protrusion 17 protruding and fixed to the inner peripheral surface of the guide cylinder 11 engages with the external spiral groove 16A, and when the first protrusion 17 is rotated integrally with the rear exterior cylinder 10B, Spiral tube 16
Is configured to advance a distance corresponding to a linear stroke between the top end portion 16a of the external spiral groove 16A and the external horizontal groove 16C.

Further, an internal spiral groove 16B is formed on the inner peripheral surface of the spiral cylinder 16, and the internal spiral groove 16B has an internal horizontal concave portion that follows the starting end when the proximal end side of the spiral cylinder 16 is the starting end. The groove 16D is formed to have a length that makes one round in the circumferential direction on the inner peripheral surface of the base end portion of the spiral cylinder 16.

Further, a holder guide cylinder 18 is rotatably fitted on the inner peripheral surface of the spiral cylinder 16, and a guide 18 is provided from the bottom of the holder guide cylinder 18.
a protrudes, and this guide element 18a engages with the vertical slit 11b of the guide cylinder 11 to guide the movement of the holder guide cylinder 18 in the axial direction, and the holder guide cylinder 18 guides the guide cylinder 11 and the rear exterior cylinder.
It is designed to rotate together with the 10B.

Further, the holder guide cylinder 18 is regulated so that it cannot slide in the axial direction of the spiral cylinder 16 due to the engagement by the engagement claw portions 18e and 18f. Further, also in this holder guide cylinder 18, vertical slits 18b are formed in the longitudinal direction of the peripheral surface, and horizontal slits 18c and 18d are respectively formed at the tip and the base end of the vertical slits 18b, as shown in FIG. Are formed. The length of each of the horizontal slits 18c and 18d becomes a length that makes one round around the outer circumference or the inner circumference of the spiral cylinder 16 when the lengths of the outer horizontal concave groove 16C and the inner horizontal concave groove 16D are added thereto.

A holder 20 holding a stick-shaped cosmetic material 19 such as lipstick is fitted on the inner peripheral surface of the holder guide cylinder 18 so as to be movable back and forth in the axial direction. A second protrusion 21 is provided on the outer peripheral surface of the holder 20, and the second protrusion 21 is engaged with the internal spiral groove 16B of the spiral cylinder 16 through the vertical slit 18b of the holder guide cylinder 18. ing.

Next, the operation mode and operation of the embodiment having the above configuration will be described. First, in the initial state of FIG. 1, the first protrusion 17 is located at the start end of the external spiral groove 16A of the spiral cylinder 16, the second protrusion 21 of the holder 20 passes through the horizontal slit 18d, and the spiral cylinder The inner edge 16e of the inner horizontal groove 16D of 16 abuts.

When it is integrated with the front exterior cylinder 10A via 5, the rear exterior cylinder 10B, the guide cylinder 11, the holder guide cylinder 18, and the holder 20 are integrally rotated with respect to the wire cylinder 16, so that the first protrusion 17 spirals. The outer spiral groove 16A of the cylinder 16 descends down the slope from the top end 16a, and the spiral cylinder 16 moves forward in the guide cylinder 11 and the front exterior cylinder 10A by a predetermined distance in the opposite direction.

Due to the forward movement of the spiral cylinder 16, the tip end of the spiral cylinder 16 comes into contact with the end 14b of the torsion coil spring 14 from below to bend and displace it. By this action, the coil portion 14c of the torsion coil spring 14 escapes to the outside, in other words, moves outward in the radial direction orthogonal to the longitudinal axis of the front exterior cylinder 10A, and the lid 13 also extends to the tip of the spiral cylinder 16 in the meantime. The pushing force of the portion causes the torsion coil spring 14 to rotate about the virtual axis of the coil portion 14c, thereby opening the open end of the front exterior cylinder 10A. At this time, the holder guide cylinder 18 and the holder 20 are also advanced by the same distance along with the spiral cylinder 16.

During this time, the second protrusion 21 of the holder 20 moves in the internal horizontal concave groove 16D on the inner surface of the spiral cylinder 16 to the start end of the internal spiral concave groove 16B, and exits the horizontal slit 18d to the base end of the vertical slit 18b. is made of.
