Constitutes the screwing portion 10 with respect to. And the screwing part 10
At the lower end of the blade, the lower edge is saw-toothed through four easily breakable connecting portions provided in a symmetrical manner, that is, the easily breakable portion 11.
A cylindrical blade 12a is provided continuously.

The cylindrical blade 12 is provided with a notch 13 at an upper diametrically symmetric position, a notch edge facing the cylindrical portion 8 of the lid 2 as an inclined surface 14, and from the side of the cylindrical portion 8. Is the slope
A projecting piece 15 is provided facing the projecting piece 14, and the inclined surface 14 and the projecting piece 15 constitute separating means by a cam structure. That is, the lid 2
When is rotated with respect to the cylindrical blade 12 in the direction of arrow 16, a force in a direction in which the cylindrical blade 12 is separated from the lid 2 is obtained.

A ridge 17 is provided along the longitudinal direction at a position diametrically symmetric on the outer wall of the cylindrical blade 12.

The assembly of the cylindrical body 1 and the lid 2 is performed by forcibly pushing the lid 2 into the inside of the cylindrical body 1, and the thread 5 of the cylindrical body 1 and the cylindrical shape on the side of the lid 2 are pushed. The threads 9 provided on the portion 8 are engaged with each other, and the projections 6 provided on the inner wall of the cylindrical body 1 and the projections 17 provided on the outside of the cylindrical blade 12 are engaged with each other.

In this embodiment, compared to the height of the cylindrical body 1,
The length of the cylindrical blade 12 connected to the cylindrical blade 12 through the easily breakable portion 11 is short, and the saw blade 12a of the cylindrical blade 12 projects from the lower opening of the cylindrical body 1 when assembled. There is no.

The spout of the container of the above embodiment is attached by welding the annular ridge 4 of the cylindrical body 1 to the container wall 18 shown by a chain line in FIG. The container wall 18 is configured by laminating a synthetic resin film 18b on the front and back of a paper plate 18a, and the portion to which this spout is attached is formed with a through hole 18b in advance in the paper plate 18a and only the synthetic resin film 18b is formed. The opening portion 28 is formed by the following. Therefore, if the diameter of the cylindrical blade 12 is smaller than the diameter of the opening portion 28, it is advantageous because a margin can be obtained in the mounting accuracy of the cylindrical body 1 to the container wall 18.

When the lid 2 is rotated in the direction of the arrow 16 at the time of opening the container, the screwing portion 10 and the cylindrical body 1 are unscrewed as shown in FIG. Since the provided cylindrical blade 12 is prevented from rotating by the engagement of the ridge 17 and the ridge 6, the easily breakable portion 11 is broken and becomes separate from the lid 2,
It moves in the direction of arrow 19 by the action of the separating means between the projecting piece 15 and the inclined surface 14. As a result, the container wall 18 is broken open by the serrated blade 12a of the cylindrical blade 12, as shown in the figure.

The breaking opening is completed by rotating the lid 2 by about 90 degrees (since the inclined surface 14 is formed in a range of about 90 degrees).
When the screw is rotated to completely unscrew the threaded portion 10, the contents of the container can be poured out through the cylinder 1. By screwing the lid 2 back onto the cylinder 1, the opened cylinder 1 can be closed.

The engagement between the tubular portion 8 of the lid 2 and the inside of the opening of the tubular body 1 is not limited to the threaded portion 10 in which the thread 9 is provided on the tubular portion 8 as in the above embodiment. Instead, as shown in FIG. 5, an annular ridge 30 is provided inside the opening of the cylindrical body 1, and an annular ridge 31 is also provided on the cylindrical portion 8 of the lid 2 so as to engage with each other. Can also.

In this case, the rotation of the lid 2 can only separate the cylindrical blade 12. Therefore, after the break opening of the container wall is performed, the lid 2 is pulled out from the cylindrical body 1 or pushed in, so that the cylindrical body 12 is removed. 1 is to be opened and closed.

The annular ridges 30 and 31 may be continuous but may be discontinuous at a predetermined angle to facilitate removal of the lid 2.

Further, the top plate 7 of the lid 2 may be formed in a plane circular or polygonal shape so that the directionality (in the rotation direction) with respect to the cylindrical body 1 is eliminated. In this case, a large number of ridges 6 provided on the inner wall of the cylindrical body 1 are formed at predetermined intervals, and the ridges 17 of the cylindrical blade 12 are engaged even when the lid 2 is inserted in any direction. You should be able to do it.

Next, the embodiment shown in FIGS. 6 to 8 will be described. Structurally, the same parts as those of the above embodiment are denoted by the same reference numerals, and description thereof will be omitted.

The thread 5 provided inside the opening of the cylindrical body 1 is provided discontinuously at every 90 degrees, and below the discontinuous portion of the thread 5,
Guide ridges 20 and 20 are installed vertically, and a vertical groove 21 between guide ridges 20 and 20 is provided.
Is formed. The lid 2 has a tubular blade 12 connected to the tubular portion 8 via an easily breakable portion 11, and a lower end of the tubular portion 8 and the tubular blade 12.
The upper end of the upper surface is formed by separating the inclined surfaces 22 and 23 having the gradients in opposite directions every 90 degrees in the circumferential direction.

The assembly of the cylindrical body 1 and the lid 2 in this embodiment is performed by pushing the lid 2 into the cylindrical body 1 by aligning the positions of the ridges 17 and the longitudinal grooves 21, and engaging the thread 5 and the thread 9. Combine.

FIG. 9 shows a state of being attached to the container wall 18 and a state of opening. The opening of the container is performed by rotating the lid 2 in the same manner as in the previous embodiment, and after the easily breakable portion 11 is broken, the inclined surface 22 of the cylindrical portion 8 of the lid 2 and the inclination of the cylindrical blade 12 are adjusted. The cylindrical blade 12 is pushed out by the separating means by the surface 23, and the container wall 18 is broken open.

Container wall 18 that is broken open by the sawtooth blade 12a of the cylindrical blade 12
Is formed by laminating synthetic resin film layers 25 and 26 on the front and back surfaces of a paper layer 24 as shown in FIG.
An annular marking line (score) 27 is provided in advance at a position opposing to, and is a scheduled opening portion. Therefore, by making the diameter of the cylindrical blade 12 smaller than the diameter of the annular marking line 27, it is possible to obtain a margin in the accuracy of the mounting position of the cylindrical body 1 with respect to the container wall 18. The portion of the saw blade 12a of the cylindrical blade 12 may be an end surface of the cylinder without being sharpened, or the end of the cylinder may be tapered so that the tip side becomes thinner.

In the above two embodiments, the screwing portion 10 of the lid 2 to the cylinder 1 is used.
The length continuously connected to the mounting portion by the easy cutting portion 11 of the cylindrical blade 12 is set to be shorter than the height of the cylindrical body 1. This is when the lid 2 is assembled to the cylinder 1
The saw-toothed blade 12 of the cylindrical blade 12 from the lower end of the cylindrical body 1 (the side of the annular flange 3)
This was effective in preventing a from protruding.

However, the length connected to the mounting portion and the cylindrical blade 12 through the easily breakable portion 11 was made longer than the height of the cylindrical body 1 and the cover 2 was rotated so as to be screwed into the cylindrical body 1. Sometimes, the function of the separating means is obtained (for example, FIGS. 7 to 9).
The embodiment shown in the figure is also a good one. In this case, the lid 2
The opening of the container wall 18 is made by the operation of screwing the container into the cylinder 1, and the opening of the cylinder 1 can be closed by the top plate 7 of the lid 2. Becomes possible.

Next, in the embodiment shown in FIG.
In addition to forming 12a, there is no rotation preventing means such as a ridge or a vertical groove between the outer wall of the cylindrical blade 12 and the inner wall of the cylindrical body 1 so that the cylindrical blade 12 can be rotated. The length of the cylindrical portion 8 of the lid 2 connected to the cylindrical blade 12 via the easily breakable portion 11 is longer than the height of the cylindrical body 1.

The opening operation in this embodiment is performed by rotating the lid 2 in a direction in which the lid 2 is screwed into the cylindrical body 1. This rotation causes the cylindrical blade 12
First, it descends while rotating with the lid 2 and moves toward the container wall 18 side. When the saw-toothed blade 12a of the cylindrical blade 12 bites into the container wall 18, the rotation is hindered. As a result, the easily breakable portion 11 integrating the lid 2 and the cylindrical blade 12 is broken. After the easily breakable portion 11 breaks, the separating means by the inclined surfaces 22 and 23 acts, and the cylindrical blade 12 is strongly pushed down toward the container wall 18 to break and open the container wall 18.

(Effects of the Invention) As described above, according to the invention, there is an effect that the opening of the container wall can be broken by rotating the lid,
Since the spout is composed of two members, a cylindrical body that can be attached to the container wall and a lid that is integrated through a connection part that can easily break the cylindrical blade, the effect of improving the efficiency of production and assembly can be improved. is there.

In addition, since the cylindrical blade is connected to the lid, no burrs remain on the cylindrical body after opening, and there is an effect that a user can provide a safe container without a risk of injuring the hand or mouth at the edge of the cylindrical body. .

The length of the lid or the threaded part connected to the cylindrical blade via the easily breakable connecting part was set to the length equal to or less than the height of the cylindrical body. Therefore, there is no danger that the lower edge of the cylindrical blade protrudes from the cylindrical body, and there is an effect that it is possible to prevent the container wall from being unexpectedly broken.

Further, when the diameter of the cylindrical blade is smaller than the diameter of the opening portion provided in advance on the container wall, there is a margin in the accuracy of the fixing position of the cylindrical body to the container wall, which is advantageous in the fixing work.
