Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a container with a screw-type cap.

[0002]

[Prior Art]

 Threaded caps are widely used.

[0003]

[Problems to be solved by the device]

 In the conventional screw cap, the cap rotation speed for screwing is the same as the cap rotation speed for screwing. Generally, the screwed portion is liable to loosen due to vibrations and the like, and in order to prevent the loosening, the lead of the screw is reduced and the screwing length is increased. Since the number of rotations for unscrewing increases, the operation becomes troublesome.

The present invention does not reduce the number of rotations when the cap is screwed, which is useful for preventing loosening, and accurately rotates the cap slightly so that the rotation when the cap is unscrewed is not necessary. The cylindrical part of the female screw that is screwed into the male screw of the neck is pulled up to the top so that the lid can be opened.

[0005]

[Means for Solving the Problems]

 A container body 1 having a male screw 2 on the outer surface of the mouth / neck portion 3 standing upright, and a cap 4 screwed to the outer surface of the mouth / neck portion 3 for sealing the upper end surface of the mouth / neck portion. From both the left and right parts of the top wall 6, elastically deformable peripheral wall partial plates 7, 7 having female screw parts 8, 8 for screwing with the male screw parts on the left and right sides of the mouth and neck are hung down. An inner cap 5 that erects a first fitting cylinder 10 that surrounds the first engagement strip 9 from the top wall; and a second engagement strip 12 that rotatably fits to the first engagement strip. The second fitting cylinder 13 is hung from the second top wall 14, and the outer cap 11 that hangs around the inner cap 5 from the outer circumference of the second top wall 14 and hangs the peripheral wall 15 is formed. The lower outer surface of the first engaging protrusion 18 and a plurality of second engaging protrusions 19 at equal intervals from the lower inner surface of the peripheral wall 7, and the first and second engaging protrusions thereof. The first and second engaging protrusions are provided so as to be engageable with a play allowance when the outer cap is rotated, and the first and second engaging protrusions engage at least one when engaging in the outer cap tightening direction. The tip end surface of the protrusion is in contact with the peripheral wall 15 or the peripheral wall partial plate 7, and when the outer cap is engaged in the loosening direction, the first engagement protrusion tip and the peripheral wall 15 and the second engagement are engaged. A clearance allowance for screwing and detaching the peripheral wall partial plate 7 can be formed between the tip of the protrusion and the peripheral wall partial plate.

[0006]

[Action]

 When the outer cap 11 is rotated in the loosening direction, that is, the counterclockwise direction from the screwed state shown in FIGS. 1 and 2, the second engagement protrusion 19 is moved to the first engagement protrusion 18 as shown in FIG. Touch the side of the tightening direction. In this state, between the tip end surface of the first engaging protrusion 18 and the inner surface of the peripheral wall of the outer cap 11, and between the second engaging protrusion 9 and the outer surface of the peripheral wall partial plate 7 of the inner cap 5. Since the gaps 20 and 21 are formed respectively, if the cap 4 is strongly pulled upward from this state, the female screw portions 8 and 8 climb onto the male screw 2 and the peripheral wall partial plates 7 and 7 of the inner cap are pulled out. The cap 4 can be removed from the outer surface of the mouth / neck part 3 by pulling it upwards against the elasticity, so that the peripheral wall partial plates 7 and 7 can be removed. Elastic return.

When the cap is screwed, it can be screwed in the same manner as in a normal case.

【Example】

 Reference numeral 1 denotes a container body for erecting a mouth / neck portion 3 having a male screw 2 attached to the outer surface thereof.

Reference numeral 4 denotes a cap, which comprises an inner cap and an outer cap.

The inner cap 5 hangs elastically deformable peripheral wall partial plates 7 and 7 from both left and right portions of the first top wall 6 that seals the upper end surface of the mouth and neck. These plates have a shape in which the front and rear portions of the peripheral wall to be screwed onto the outer surface of the mouth and neck are largely cut out, and internal thread portions 8 are provided on the inner surface thereof. The lower part will be described later. Further, a first fitting cylinder 10 around which a first engaging strip 9 is provided is erected from the first top wall 6. The first engaging strip may be a groove as shown, or may be a projecting strip.

Reference numeral 11 denotes an outer cap, which hangs a second fitting cylinder 13 having a second engagement strip 12 rotatably fitted to the first engagement strip 9 from a second top wall 14. In the illustrated example, the second engaging strips are used as protrusions and are fitted into the grooves formed by the first engaging strips, but they may be provided in the opposite manner, and the second fitting tube 13 may be used as the first fitting tube. 10 Instead of fitting on the outer surface, it may be fitted on the inner surface. A peripheral wall 15 is suspended from the outer circumference of the second top wall 14 so as to surround the inner cap 5.

A first engagement protrusion 18 and a second engagement protrusion 19 are attached to the lower outer surface of the peripheral wall partial plates 7, 7 and the lower inner surface of the peripheral wall 15, respectively. These two engaging projections are provided so as to be engaged by the rotation of the outer cap 11 with an appropriate play allowance, and the first engaging projection 18 may be a single piece. The second engaging protrusions 19 are provided at equal intervals on the entire inner surface of the lower portion of the peripheral wall. As shown in FIG. 2 and FIG. 3, the outer surface of the peripheral wall partial plate 7 on the side of the first engagement protrusion 18 is located on the side of the cap loosening direction, that is, on the side of the counterclockwise direction in the illustrated example. The diameter is large and the outer diameter of the side portion in the cap tightening direction, that is, the side portion in the clockwise direction in the illustrated example is small, and the inner surface of the peripheral wall portion on the side of the second engaging protrusion 19 is small. , Inclined portions in the circumferential direction are provided so that the partial inner diameter is large on the side portion in the cap loosening direction and small on the side portion in the cap tightening direction, and as shown in FIG. When the side surface of the first engaging protrusion 18 in the loosening direction and the side surface of the second engaging protrusion 19 in the tightening direction are in contact with each other, at least one of the tips of the first and second engaging protrusions is at least one of them. It contacts the inner surface of the peripheral wall and the outer surface of the peripheral wall partial plates 7, 7, and as shown in FIG. When the surface comes into contact with the side surface of the second engaging protrusion in the loosening direction, the peripheral wall partial plate 7 is screwed and disengaged between the tips of both engaging protrusions and the inner wall of the peripheral wall and the peripheral wall partial plate 7. The relief clearance, that is, the clearances 20, 21 are formed so that the female screw portions 8, 8 can be disengaged from the male screw 2 when the peripheral wall partial plates 7, 7 move away from each other.

[0013]

[Effect of the Invention] Since the present invention has the above-described configuration, the outer cap 11 is slightly rotated when the lid is opened, and then the outer cap is put on the container body regardless of the screw cap. The cap can be removed simply by pulling it up, and the cap can be removed easily and quickly.Therefore, it has the advantage of being a screw-type cap, that is, the certainty of cap closure by screw tightening. In addition, the cap can be easily and quickly opened by so-called undercut fitting.
