[Problems to be solved by the invention]
Among the conventional positioning containers for caps described above, the one shown in FIG. 4 uses a projection provided on the shoulder of the container main body to perform the rotational positioning of the cap. However, when the container main body is a glass bottle, It has been difficult to form a projection with an accurate dimension at an accurate position of the shoulder. Therefore, the click feeling when the cap is rotated is unstable, and the quality of the product is likely to vary. In some cases, the locking state of the cap is loose and the cap may be returned carelessly. Further, since an elastic member is required separately from the cap for closing the bottle mouth, there is a problem that the number of parts is increased and the assembling time is required.
[0006]
Further, in the one shown in FIG. 5, in order to store the pressing body in the cap, the cap must have a double structure composed of an outer lid and an inner lid, which also has a large number of parts, and There is a problem that the cost increases because the assembling work is also required.
[0007]

In order to solve the above-mentioned problems, in the present invention, a positioning container for a cap is provided below a position near a terminal end of a screw portion formed on an outer periphery of a mouth portion, and a glass container main body provided with a rib extending vertically in a vertical direction. A screw ridge is provided on the inner wall surface of the inner peripheral wall, the elastic ridge having a locking projection is provided at an end position of the screw ridge. A cap made of a synthetic resin integrally formed on the peripheral wall, and at a fastening end position of the cap, a locking projection provided on the cap rides over a climbing rib provided on the container body, and the cap is fixed to a predetermined position with respect to the container body. It is characterized in that it is locked at the rotation position.
[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described in detail based on illustrated embodiments.
[0010]
FIG. 1 is an exploded perspective view showing an embodiment of the container according to the present invention. In the figure, reference numeral 1 denotes a container main body formed in a rectangular tube shape from glass. On a shoulder 4 of the container main body 1, a mouth portion 2 having a screw portion 3 formed on the outer periphery is provided.
[0011]
Reference numeral 7 denotes a cap which is screwed into the mouth 2 of the container main body 1. The cap 7 is provided inside the outer peripheral wall 8 with an outer peripheral wall 8 having substantially the same shape as the outer shape of the container main body 1. It is formed of a synthetic resin in a double structure including a cylindrical inner peripheral wall 9. On the inner wall surface of the inner peripheral wall 9, a screw ridge 10 that is screwed with the screw portion 3 provided on the mouth 2 of the container body 1 is provided.
[0012]
In FIG. 1, reference numeral 6 denotes a seal packing mounted on the back surface of the cap 7.
[0013]
Here, in the positioning container of the present invention, at a position near the end (lower end in FIG. 1) of the screw portion 3 provided in the mouth portion 2 of the container main body 1, the screw root 3a is vertically closed below the screw portion 3 below. As shown in FIG.
[0014]
An elastic piece 11 is formed on the inner peripheral wall 9 of the cap 7 on which the screw ridge 10 is provided so that the terminal position (the lower end position in FIG. 1) of the screw ridge 10 is cut out in a substantially U-shape. At the same time, a locking projection 12 is provided on the surface of the elastic piece 11 at a position continuous with the end of the screw ridge 10.
[0015]
The cap 7 is formed using a mold having a conventionally known split mold core called a split mold. Therefore, the screw ridges 10 formed on the inner wall surface 9 are not continuous, and are divided into a plurality.
[0016]
The positioning container for the cap of the present invention has the above-described configuration.
[0017]
Next, the function of each part when positioning the cap will be described. First, the cap 7 is put on the mouth 2 of the container body 1 and the cap 7 is turned in the direction of tightening the screw (usually clockwise rotation). A screw ridge 10 provided on the periphery engages with a screw portion 3 provided on the mouth portion 2 of the container body 1, and is guided by the screw portion 3 to move downward. At this time, the screw ridge 10 provided on the inner periphery of the cap 7 is divided into a plurality of forms, but each is located on the extension of the screw and provided symmetrically about the center. Its function is no different from a normal screw.
[0018]
Eventually, the locking projection 12 provided on the cap 7 near the tightening end position of the cap 7 comes into contact with the climbing rib 5 provided near the end of the screw portion 3. At this time, in the container of the present invention, since the locking projection 12 is provided on the surface of the elastic piece 11 formed by a part of the inner peripheral wall 9, when the cap 7 is further tightened from this state, the elastic piece 11 bends outward (outer peripheral wall side), the locking projection 12 rides over the climbing rib 5, and the elastic piece 11 returns to its current state with its own elastic restoring force at that position, so that the cap 7 has a snap feeling. Accordingly, the locking state shown in FIG. 2 and FIG. 3 is established, and the locking is performed so as not to be inadvertently loosened. At this time, the cap 8 is positioned so that its side surface coincides with the side surface of the container body. Therefore, when the cap 7 is not closed to the locking position, the state can be seen at a glance from the outside.
[0019]
In order to remove the cap 7, it is sufficient to rotate the cap 7 in a direction to loosen the cap 7 completely opposite to the above, so that the elastic piece 11 is first bent and the locking projection 12 gets over the rib 5 and Since the locked state is released, the cap 7 is then turned in the direction of loosening and removed from the mouth 2 of the container body 1 as in a normal container.
[0020]
As described above, in the container for positioning a cap of the present invention, the cap 7 is locked and unlocked with a snap feeling, and even if the container is a non-cylindrical container, the cap 7 is fixed to the container body 1. It is locked in a state where it has been aligned.
[0021]
In the illustrated embodiment, the container has a rectangular tube shape. However, in the cap positioning container of the present invention, the cap 7 is positioned at a predetermined rotation position with respect to the container body 1. As described above, both plane shapes may be the same, and for example, the plane shape may be an elliptical shape, a polygonal shape, or a different shape such as a gourd shape or an arch shape.
[0022]
Further, in the illustrated embodiment, the elastic piece 11 has a shape in which the peripheral wall at the end position of the screw ridge 10 is cut out in a U-shape, but the elastic piece 11 is a part of the inner peripheral wall 9. For example, it may be formed by cutting the inner peripheral wall 9 into an upward U-shape or a downward U-shape.
[0023]
【The invention's effect】
As described above, in the cap positioning container of the present invention, since the elastic piece having the locking projection is formed at the end position of the screw ridge of the cap having the double peripheral wall by using the peripheral wall, The cap can be integrally formed of a synthetic resin, and the cost can be reduced in combination with the elimination of the assembling labor. Further, since no excessive force acts on this elastic piece, the operation is reliable, a reliable operation feeling is obtained, and the durability that can withstand repeated use is obtained. Further, since the overriding rib provided on the container body is provided on the outer periphery of the mouth, the overriding rib can be formed with high dimensional accuracy even in the case of a glass bottle, and is stable when the cap is locked and released. There is also an effect that a click feeling can be obtained.
