JP3670173B2 - Container with safety cap - Google Patents

Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a container with a so-called safety cap.
[0002]
[Prior art]
As a safety cap provided to prevent the infant from opening the lid, for example, the outer cap is urged upwardly and fitted to the outer surface of the inner cap, and the outer cap is raised with respect to the inner cap screwed to the container neck. If the outer cap is idle, the lid cannot be opened, but when the outer cap is pushed down against the bias and turned in the direction of opening, the inner and outer caps engage with each other so that the inner cap can be unscrewed from the mouth and neck. The cap is known.
[0003]
[Problems to be solved by the invention]
In the conventional safety cap, the outer cap must be rotated in the screwing direction while the outer cap is pressed down against the inner cap screwed to the outer surface of the mouth and neck of the container. In addition, since the two operations of pressing down for unlocking and turning for opening the lid are simultaneously performed with one hand, it is difficult for an adult to open the lid. .
[0004]
The present invention is provided so that the lid can be unlocked with one hand and the lid can be opened with the other hand so that the above-mentioned drawbacks can be removed.
[0005]

Further, the engagement between the inner teeth 35 and the engagement teeth 21 was made detachable by pushing the tip of the leaf spring inward from the state where the lock ring was pulled up to the upper limit.
[0006]
An engaging means having the first means as the second means and engaging the lock ring 41 by forcibly pulling the lock ring 41 up to the upper limit with respect to the outer peripheral wall 34 and releasing it by forcibly pushing down from the upper limit position. They were formed on the outer surface of the outer peripheral wall and the inner surface of the cylindrical portion 42 of the lock ring.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
The container of the present invention includes a container body, a cylindrical lock member, a cap, and a cylindrical lock ring.
[0008]
The container body 1 erects a large-diameter tube 4 from the upper end of the body portion 2 through the shoulder portion 3, and a small-diameter mouth neck portion 6 for screwing the cap through the inward flange 5 from the upper end of the large-diameter tube. It is desirable to attach an engagement protrusion 7 on the outer surface of the large-diameter cylinder 4 for fitting and fixing a cylindrical lock member, which will be described later, so that it cannot be pulled out and cannot be rotated.
[0009]
The cylindrical lock member 11 hangs down the middle cylinder 14 from the upper end of the inner cylinder 12 fixed to the outer surface of the large-diameter cylinder 4 via the first outward flange 13, and the second outward flange 15 from the lower end of the intermediate cylinder. Through which the outer cylinder 16 stands. Both the left and right portions of the first and second outward flanges 13 and 15 and the middle cylindrical tube wall portion between these left and right portions are notched as shown in FIG. As shown in FIG. 1, the cylinder 16 left and right cylinder wall sections are cut to the upper part of the section, and horizontal lines 17 and 17 are separated, and these lines are separated from the front end of the horizontal line to the lower end of the outer cylinder, and vertical lines 18 and 18 are drilled. The springs 19 and 19 are formed. Further, as shown in FIG. 4, engaging plates 22 and 22 having engaging teeth 21 on their outer surfaces are erected from the lower edges of the tip end portions of the two leaf springs through the inwardly extending plates 20 and 20, respectively. A gap is provided between the inner surface of the engagement plate and the inner cylinder 12.
[0010]
The cap 31 hangs a screwed tube 32 to the outer surface of the mouth and neck from the outer periphery of the top plate 33, hangs an outer peripheral wall 34 from the outer periphery of the top plate, and forms a lower part of the outer peripheral wall as an internal gear-shaped tube on the inner surface of the tube. A plurality of internal teeth 35 are provided. The internal gear-shaped cylinder is fitted between the middle cylinder 14 and the engagement plate 22 and the outer cylinder 16 as described above, and the inner teeth 35 are not engaged with the engagement teeth 21 of the engagement plate 22 and the cap screwing direction. The inner teeth and the engaging teeth are both formed into a saw-tooth shape formed of an upright surface and an inclined surface so as to slide and engage with each other in the loosening direction. The outer peripheral wall 34 has a slightly larger outer diameter at the lower half portion relative to the upper half portion, and a ridge 36 is provided around the upper end of the large outer diameter portion and a small groove 37 is provided at the lower end portion of the ridge. There are around.
[0011]
A cylindrical lock ring 41 is fitted to the outer surface of the outer peripheral wall 34 of the cap 31 so as to be movable up and down for a fixed stroke. The lock ring has an upper end portion of the cylindrical portion 42 bent upward and inward to form an engaging portion 43, and a wide concave groove 44 is provided on the lower inner surface of the engaging portion, and at the lower end of the concave groove. A small ridge 45 is provided around. Then, the protrusion 36 of the above-described cap is fitted into the concave groove so that the lock ring 41 can be moved up and down, and when the lock ring is raised to the upper limit, it is locked into the small concave groove 37 of the outer peripheral wall of the cap. The small protrusion 45 of the ring can be fitted to keep the lock ring pulled up. Further, the lock ring has an engaging protrusion 46 on the outer surface of the intermediate portion, and the lower end of the cylindrical portion is cut off in the state shown in FIG. The lower end of the cylindrical portion is provided so as to be disengaged above the leaf spring 19 when engaged with the inner surface of the portion and when pulled up to the upper limit as shown in FIG. Yes.
[0012]
In the above configuration, in the cap screwed state shown in FIG. 1, the inner teeth 35 and the engaging teeth 21 are engaged with each other so that the cap cannot be screwed off.
[0013]
When the cap is screwed off, the lock ring 41 is pulled up as shown in FIG. 2, and the lower end of the cylindrical portion is moved above the leaf spring 19. When the leaf springs 19 and 19 are pressed inward from this state as shown in FIG. 3, the engagement between the inner teeth and the engagement teeth is released, so that the cap 31 can be screwed together with the lock ring.
[0014]
When the cap is screwed, the inner teeth 35 and the engaging teeth 21 slide and do not mesh with each other, so that they can be screwed together. The lock ring may be lowered to the lower limit either before or after the cap screwing.
[0015]
【The invention's effect】
The present invention has the above-described configuration, and the inner teeth 35 and the engaging teeth 21 slide when the cap is screwed, so that the cap can be screwed and engaged in the screwing direction. The cap cannot be screwed unless the teeth are engaged, that is, the lock is removed. The lock can be removed by pulling up the lock ring 41 to the upper limit and then pushing the leaf springs 19 and 19 inward. With the other hand holding, the leaf springs 19, 19 can be pushed inwardly to disengage the engaging teeth 21 from the internal teeth 35, and then the cap 31 can be unscrewed with the one hand, thus removing the lock. And the cap can be unscrewed with different hands, so that the cap can be easily unscrewed.
[0016]
The operation of pulling the leaf spring inward by lowering the lock ring by its own weight by providing an engaging means for lifting the lock ring to the upper limit and locking it to the upper limit position as in the case of claim 2. Can be prevented.
