TECHNICAL FIELD OF THE INVENTION
The present invention relates to a container with a lid, such as a water bottle and a thermos bottle.
[0002]
[Prior art]
Generally, as shown in FIGS. 6 and 7, a container with a lid is provided with a mouth-side screw thread 5 from the start end 3 to the end 4 within one turn on the outer peripheral surface of the mouth 2 of the container body 1. A lid-side thread 7 is provided on the inner peripheral surface of the cup-shaped lid 6 that covers the mouth 2. A screw end interval A of a predetermined size is formed between the start end 8 of the lid side screw 7 and the end portion 9 located within one turn from the start end 8. Further, the intermediate portion of the cover-side screw 7 is notched, and a predetermined distance is provided between the start-side intermediate end 11 continuous with the start 8 of the cover-side screw 7 and the terminal-side intermediate end 12 continuous with the end 9. An intermediate interval B having a size of
[0003]
The above screw end interval A and the intermediate interval B are provided at a position of about 90 degrees on both sides of the handle 13, and when the user grips the handle 13 and drinks the beverage with the lid 6, the lips touch the lid side thread 7. This also prevents the liquid from running out of the beverage.
[0004]
The above-mentioned lid 6 is screwed by engaging the starting end 8 of the lid-side screw 7 with the lower surface of the starting end 3 of the mouth-side screw 5 and rotating it by approximately 270 degrees. At the end of the screwing, The click concave portion 14 provided near the starting end 8 of the cover side screw thread 7 fits into the click convex portion 15 provided at the end portion of the mouth side screw thread 5 to give a click feeling.
[0005]
In the drawing, reference numeral 16 denotes a screw thread for tightening the inner plug screw.
[0006]
[Problems to be solved by the invention]
In the container with a lid as described above, when the lid 6 is screwed, the start end 8 of the screw 7 on the lid side should normally engage with the start end 3 of the screw 5 on the mouth as described above. As shown in FIG. 8 (a), the distance between the terminal intermediate end portion 12 of the lid side thread 7 and the starting end 3 of the mouth side thread 5 is substantially zero, so that the lid is slightly inclined. Only as shown in FIG. 8B, the end-side intermediate end portion 12 of the cover-side screw 7 may be engaged with the start end 3 of the mouth-side screw 5 first.
[0007]
When the lid 6 is rotated without noticing such engagement, the end-side intermediate end portion 12 enters the lower surface of the start end 3 of the mouth-side thread 5 (when viewed from the container body 1 side, the portion at the intermediate interval B) As a result, the start end 3 of the mouth side thread 5 rides on the end side intermediate end portion 12). Such a situation is a so-called “oblique insertion” of the lid, and screwing of the lid 6 becomes impossible.
[0008]
Therefore, an object of the present invention is to provide a container with a lid having a screw structure in which the above-described oblique insertion does not occur.
[0009]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention provides a mouth-side thread from the start end to the end within one turn on an outer circumferential surface of a mouth of a container body, and an inner circumferential surface of a lid covered on the mouth. A cover-side screw is provided, a predetermined screw end interval is provided between a start end of the cover-side screw and an end within one turn from the start end, and a middle portion of the cover-side screw is cut out. In the container with a lid having a start end side middle end at one end of the intermediate interval to be provided, and a terminal end middle end at the other end, a regulating protrusion is provided on a screw upper surface near the start end of the mouth side screw, The restricting projection is brought into contact with the lower surface of the intermediate end of the starting end to prevent the terminal intermediate end of the cover-side screw from entering the lower surface of the starting end of the mouth-side screw. .
[0010]
A configuration in which the length from the starting end of the mouth-side thread to the regulating protrusion is equal to the size of the intermediate space or a size set in the vicinity thereof, or the upper end surface of the regulating protrusion Is formed on a flat surface of a fixed length along the mouth-side screw, both the upper surface of the starting end of the mouth-side screw and the lower surface of the terminal-side intermediate end of the lid-side screw. Alternatively, a configuration in which one of them is rounded or tapered can be employed.
[0011]
In addition, as another means for solving the above-mentioned problem, a regulating convex portion is provided on the lower surface of the screw near the starting end intermediate end of the lid-side screw, and the restricting convex is formed as the opening-side screw. It is also possible to adopt a configuration in which the upper end is abutted on the upper side screw to prevent the middle end portion on the end side of the cover side screw from entering the lower surface of the start end of the mouth side screw.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. As shown in FIGS. 1 and 2, the liquid container according to the embodiment has the same configuration as that of the above-described conventional example. Therefore, the same portions are denoted by the same reference numerals, and redundant description will be omitted.
[0013]
The difference from the conventional configuration is that a regulating protrusion 17 is provided on the upper surface of the screw near the starting end 3 of the mouth-side screw 5. The restricting projection 17 has a trapezoidal shape in which the upper end surface 18 has a flat surface of a fixed length in the length direction of the thread. The length from the front end 3 of the front end 18a of the flat surface (the end on the side of the start end 3; see FIG. 3A) is equal to or close to the size of the intermediate space B, and the start end 3 of the rear end 18b. Is greater than the intermediate interval B.
[0014]
The intended purpose can be achieved even when the regulating protrusion 17 is moved closer to the start end 3 than the above position and the rear end 18b is provided at a position smaller than the intermediate interval B from the start end 3. Conversely, the front end 18a can be provided at a position larger than the intermediate interval B as shown in FIG. It is preferable to set the position not to exceed the degree.
[0015]
When the lid 6 is placed over the mouth 2 of the container body 1, as shown in FIG. Even when there is, the restricting convex portion 17 abuts on the lower surface of the starting end side intermediate end portion 11 (in other words, the lower surface of the starting end side intermediate end portion 11 rests on the upper end surface 18 of the restricting convex portion 17). An interval C having a certain size is formed between the start end 3 of the side thread 5 and the end-side intermediate end 12 of the lid side thread 7.
[0016]
For this reason, even if the cover 6 is tilted to such an extent as to normally occur in the cover tightening operation, the above-mentioned interval C does not become minus, so that the terminal-side intermediate end portion 12 of the cover-side screw 7 is connected to the mouth-side screw 5. The situation of entering the lower surface of the starting end 3, that is, the oblique entry does not occur.
[0017]
The shape of the regulating protrusion 17 forming the above-mentioned interval C does not necessarily have to be a trapezoid. It may be a simple mountain-shaped restricting convex portion 17 'as shown in FIG. The position of the restricting projection 17 'is set to a position equal to or larger than the intermediate interval B from the start end 3. However, in the case of the trapezoidal regulating protrusion 17 as described above, the flat upper end surface 18 supports the lid 6 stably and is hard to be inclined, so that the oblique entry can be more effectively prevented.
[0018]
After the oblique entry is prevented as described above, with the rotation of the lid 6, the starting end 8 of the lid-side screw 7 engages with the lower surface of the starting end 3 of the mouth-side screw 5, and screw tightening is started. (See FIG. 3 (b).) Further, the portion of the intermediate interval B passes below the start end 3 of the mouth side thread 5 (see FIG. 3 (c)), and rotates about 270 degrees from the start of screw tightening. As a result, the click concave portion 14 near the starting end 8 of the lid side screw thread 7 fits into the click convex portion 15 near the terminal end 9 of the mouth side screw thread 5 to give a click feeling (see FIG. 3D).
[0019]
The starting end 3 of the mouth-side thread 5 and the end-side intermediate end 12 of the lid-side thread 7 may collide with each other when the inclination of the lid 6 is increased. As shown in the figure, the upper surface 21 of the start end 3 and the lower surface 21 'of the end-side intermediate end portion 12 are rounded or tapered so that the collision is reduced and the screw is guided in the normal screw tightening direction. Is desirable.
[0020]
In the above embodiment, the regulating protrusion 17 is provided on the mouth-side screw thread 5, but this regulating protrusion 17 is provided on the start-side intermediate end 11 of the lid-side screw thread 7 as shown in FIG. It may be provided on the lower surface. When provided at this position, the restricting convex portion 17 abuts on the upper surface of the screw near the starting end 3 of the mouth-side screw 5, so that the intermediate between the starting end 3 of the mouth-side screw 5 and the end of the lid-side screw 7. An interval C of a certain size is formed between the end portion 12 and the end portion 12.
[0021]
For this reason, as in the case described above, the interval C does not become negative in the normal lid tightening operation, so that the end-side intermediate end portion 12 of the lid-side screw 7 is connected to the start end 3 of the mouth-side screw 5. Diagonal entry into the lower surface does not occur.
[0022]
【The invention's effect】
As described above, the present invention provides a regulating protrusion on the upper surface of the screw near the start end of the mouth-side screw, and abuts the regulating protrusion on the lower surface of the intermediate portion on the end side, or a cover-side screw. A regulating protrusion is provided on the lower surface of the screw thread near the starting end intermediate end of the thread, and the regulating convex is brought into contact with the upper surface of the mouth-side thread, whereby the terminal-side intermediate end of the lid-side thread is formed. The situation in which the portion enters the lower surface of the start end of the mouth-side thread, that is, oblique entry is prevented, and the lid can be smoothly screwed into the mouth of the container body.
