FIG. 1 is a front view showing the main parts of a container with a bottle spout cap according to a first embodiment of the present invention, and FIG. 2 is a half cross section taken along the container axis O from a position on the outer peripheral side II in FIG. 3 are cross-sectional views taken along line III--III in FIG. 1.
In the following description, the direction indicated by the arrow α in the circumferential direction around the container axis O passing through the center of the container body in FIG. 1 is defined as the opening direction, and the opposite direction is defined as the reverse opening direction. Further, a direction along the container axis O is defined as an axial direction (or longitudinal direction), and a direction orthogonal to this container axis O is defined as a radial direction.

As shown in FIGS. 1 and 2, the container with a bottle opening cap of the present invention includes an upper lid part 2, a sealing cylinder part 3 connected to the upper lid part 2, and a sealing cylinder part 3 provided on the lower surface of the upper lid part 2. The bottle opening cap 1 includes a bottle opening cap 1 having a stopper body 4 and integrally formed of a synthetic resin material, and a container body 20 to which the bottle opening cap 1 is attached.
An outer peripheral wall 5 is provided hanging from the outer peripheral edge of the upper lid part 2. This outer peripheral wall 5 is formed with a knurling 5a, which is composed of a plurality of vertical grooves and exhibits an anti-slip effect particularly in the circumferential direction.
Below the outer circumferential wall 5 constituting the upper lid part 2, a sealing cylinder part 3 formed by forming a side wall part 6 into a cylindrical shape is connected. Between the outer circumferential wall 5 on the upper lid part 2 side and the side wall part 6 on the sealing tube part 3 side, there is a vertical separation part that is breakable and formed through a thin part 11a formed by thinning the bottom of the recessed groove. 11 are arranged horizontally around the periphery. By breaking the vertical separation part 11, it is possible to separate the upper lid part 2 and the sealing tube part 3 in the vertical direction.

A window hole 7 that penetrates in the radial direction is bored in the axially central position of the sealing cylinder part 3 . The window holes 7 are opened in the shape of a horizontal band (rectangular shape having long sides in the circumferential direction), and are formed in plurality at predetermined intervals in the circumferential direction.
In the sealing cylinder part 3, a window hole 7 at an arbitrary location is arranged in an inclined manner between a corner on one end side in the circumferential direction of the upper edge part 7a and the vertical separation part 11. A first thin portion 12 (circumferential separation portion Q) is formed. Further, a knob 8 having a horizontal U-shape is formed at the lower end of the sealing tube 3, and a notch 10 is formed between the knob 8 and the sealing tube 3 facing in the reverse opening direction. It is formed. A second thin part 13 (circumferential separation part Q ) is formed along the knob portion 8.

Like the vertical separation part 11, the first thin part 12 and the second thin part 13 are formed so as to be breakable by thinning the bottom of the groove provided in the side wall part 6, and both of them are made breakable by thinning the groove bottom provided in the side wall part 6. A circumferential separation portion Q is formed by breaking the material in a substantially longitudinal direction and dividing it in the circumferential direction. Note that the longitudinal separation section 11 and the circumferential separation section Q are collectively referred to as a separation section.
A slit-shaped notch 14 is formed between the end 13a of the second thin-walled portion 13 and the notch 10, and the knob 8 extends radially outward from the end 13a of the second thin-walled portion 13 as a starting point. It can be easily bent and deformed. Furthermore, a protrusion 8a (protrusion P) that protrudes radially inward is formed on the inner peripheral surface of the knob 8, and an arrow α indicating the opening direction is carved on the outer peripheral surface of the knob 8. There is.

Further, on the upper edge 7a of each window hole 7, a locking portion 9 projecting outward in the radial direction in a convex curved shape is connected via a connecting portion 9a formed to be elastically deformable. It is disposed so as to be foldable toward the inner circumferential surface of the side wall portion 6 forming the portion 3 . As shown in FIG. 2, the locking part 9 is folded back toward the inner circumferential surface of the sealing cylinder part 3, and in this state, a locked part 22 is provided around the outer circumferential surface of the bottle mouth part 21 in a concave curved shape. By being locked to, movement of the bottle spout cap 1 in the axial direction along the container axis O with respect to the bottle spout portion 21 is restricted. Note that the locking portion 9 having a convex curved surface and the locked portion 22 having a concave curved surface are formed with the same radius of curvature.

As shown by the broken line in FIG. 2, the inner circumferential surface of the locking part 9, which was facing radially inward before being folded back, is in close contact with the inner circumferential surface of the side wall part 6 while facing radially outward after being folded back. do. The end portion 9b of the locking portion 9, which was located below the connecting portion 9a in the axial direction before folding back, is located above the connecting portion 9a in the axial direction after folding back, and is located within the side wall portion 6. It can come into contact with a stepped portion 6b provided on the inner circumferential surface near the lower end of the vertical separating portion 11, and further movement upward in the axial direction is restricted.

The plug body part 4 is a cylindrical member with a cavity formed inside, and its inner peripheral surface is formed without any level difference, but the outer peripheral surface has a diameter that varies from the lower surface of the upper lid part 2 to the lower end. It is formed with That is, the upper end portion 4A from the lower surface of the upper lid portion 2 to the approximately intermediate position in the axial direction is formed to have a larger diameter than the lower end portion 4B from the approximately intermediate position to the lower end. A plurality of reinforcing vertical ribs 4a are formed on the outer peripheral surface of the upper end portion 4A at predetermined intervals in the circumferential direction. The axial length of the vertical rib 4a is shorter than the axial length of the upper end 4A, and the lower end of the vertical rib 4a can come into contact with the upper end of the bottle opening 21 of the container body 20. It is. Of the upper end portion 4A, the lower part of the upper end portion 4A (the portion located below the lower end of the vertical rib 4a) is formed with a slightly larger dimension than the inner circumferential surface of the bottle mouth portion 21. It functions as a seal portion 15 that performs sealing by tightly fitting into the upper inner circumferential surface of 21.

In order to attach the bottle spout cap 1 having the above structure to the bottle spout 21 of the container body 20, first, using a jig or the like, while elastically deforming the connecting portion 9a, the locking portion 9 is attached to the sealing tube portion. 3. Push back toward the inside of the side wall portion 6 that forms part 3. As a result, the locking portion 9 faces inward in the radial direction, and the end portion 9b is set to be located above the connecting portion 9a (see FIG. 2).

Next, the bottle mouth cap 1 is plugged, and the stopper body part 4 is fitted into the bottle mouth part 21. At this time, since the lower end of the vertical rib 4a on the side of the stopper body 4 comes into contact with the upper end of the bottle spout 21, further downward movement of the bottle spout cap 1 with respect to the bottle spout 21 is restricted. At the same time, the locking part 9 enters the locked part 22 while sliding on the outer peripheral surface of the bottle spout 21 to complete the locking, and the bottle spout cap 1 moves upward relative to the bottle spout 21. is regulated.

Also, at this time, the protrusion 8 a protruding from the inner circumferential surface of the knob 8 comes into contact with the outer circumferential surface of the bottle opening 21 . As a result, as shown in FIG. 2, the tip side of the knob 8 having the protrusion 8a is deformed radially outward from the end 13a side of the second thin wall portion 13, and the outer periphery of the bottle opening 21 is deformed. A gap S is formed between the surface and the inner circumferential surface of the deformed knob part 8. Further, since the seal part 15 on the stopper part 4 side is pushed into the bottle mouth part 21 and is tightly fitted to the inner circumferential surface of the bottle mouth part 21, the container body 20 can be set in a sealed state. This operation of attaching the bottle spout cap 1 to the bottle spout 21 is performed using a capping machine (not shown).

Next, a method of opening the bottle spout cap having the above structure from the bottle mouth portion will be explained.
First, the second thin portion 13 is broken by grasping the knob 8 and rotating the pinched knob 8 in the opening direction indicated by the arrow α while pulling the knob 8. At this time, a gap S is formed between the outer circumferential surface of the bottle mouth part 21 and the inner circumferential surface of the deformed knob part 8, so that by inserting a fingertip, a nail, etc. into this gap S, the knob can be removed. The portion 8 can be easily held.
The breakage of the second thin part 13 reaches the lower edge 7b of the window hole 7, and when the knob part 8 continues to rotate in the opening direction, the first The thin wall portion 12 breaks, and the break reaches the longitudinal separation portion 11. The sealing cylinder part 3 is divided in the circumferential direction by breaking the second thin part 13 and the first thin part 12 that constitute the circumferential separating part Q in this order substantially vertically upward.
Further, the finger holding the knob 8 is pulled around the sealing cylinder part 3 in the opening direction. Then, the vertical separation part 11 is broken over the entire circumference, and the upper lid part 2 and the sealing cylinder part 3 are separated in the vertical direction, so that the sealing cylinder part 3 can be removed from the bottle mouth part 21.

Even after the sealing cylinder part 3 is removed, the stopper part 4 is tightly fitted into the bottle mouth part 21 to form a strong seal, and the top lid part 2 remains exposed above the bottle mouth part 21. Therefore, by grasping the knurling 5a formed on the outer circumferential wall 5 of the upper lid part 2 and pulling out the stopper part 4 to open it, the liquid inside the container body 20 can be poured out through the bottle mouth part 21. becomes possible.
Further, after opening the bottle, it is possible to re-close (re-cap) the bottle by tightly fitting the stopper body part 4 into the bottle mouth part 21.

FIG. 4 is a half-sectional view showing the main parts of a container with a bottle mouth cap as a second embodiment of the present invention, and FIG. 5 is a half-sectional view showing another configuration of the second embodiment.
The bottle mouth cap shown in the second embodiment differs from the first embodiment in that the knob 8 is flexibly deformed toward the outside in the radial direction, and other structures and effects are different from those in the first embodiment. Since they are the same, the same members will be described below with the same reference numerals, focusing on the differences from the first embodiment.

In the second embodiment shown in FIG. 4, instead of providing the protrusion 8a on the inner circumferential surface of the knob 8 of the first embodiment, a protrusion P is provided on the outer circumferential surface of the bottle opening 21 of the container body 20. 24. The protrusion 24 protrudes radially outward from the outer circumferential surface of the bottle mouth 21, and the protrusion 24 is formed in a convex annular shape over the entire circumference of the outer circumference of the bottle mouth 21. Alternatively, a plurality of hemispherical protrusions 24 may be formed at predetermined intervals in the circumferential direction.

Further, in another configuration of the second embodiment shown in FIG. It is configured to utilize the annular protrusion 23 originally formed in the container, and the sealing is performed so that the knob 8 rides on the annular protrusion 23 when the bottle opening cap 1 is attached to the bottle opening 21 of the container body 20. The length dimension (vertical dimension) of the cylindrical portion 3 along the axial direction is longer than that of the first and second embodiments.

As shown in FIGS. 4 and 5, when the bottle spout cap 1 is plugged and attached to the bottle spout 21 of the container main body 20, the knob 8 provided at the lower end of the sealing tube 3 will open as shown in FIG. In the second embodiment, the knob 8 rides on the protrusion 8a, and in the other configuration of the second embodiment shown in FIG. Therefore, a gap S can be formed between the inner circumferential surface of the deformed knob part 8 and the outer circumferential surface of the bottle mouth part 21. Therefore, as in the first embodiment, by inserting a fingertip, a nail, or the like into the gap S, the knob 8 can be easily grasped.

Incidentally, as in the second embodiment, the protrusions 24 are formed in a convex annular shape over the entire circumference of the outer peripheral surface of the bottle opening 21, or the protrusions 24 are semispherical and are spaced at predetermined intervals in the circumferential direction. In the configuration in which a plurality of bottles are formed, even if the bottle spout cap 1 is capped without positioning it in the circumferential direction, the knob 8 always rides on the protrusion 24 and is able to bend and deform. .

FIG. 6 is a front view showing the main parts of a container with a bottle mouth cap as a third embodiment of the present invention, and FIG. 7 is an enlarged view of area A in FIG. 6.
The main difference between the bottle opening cap 1 shown in the third embodiment and the first embodiment is that the sealing tube 3 is provided with a bellows part 16 as an elastically deformable part, and other structures and functions are different. Since this embodiment is almost the same as the first embodiment, the following explanation will focus on the points that are different from the first embodiment, and the same members will be described with the same reference numerals.

In the third embodiment shown in FIGS. 6 and 7, a bellows portion 16 is provided as an elastically deformable portion in which a part of the sealing tube portion 3 is narrowed and is elastically deformable, and a bellows portion 16 is located at a position opposite to the knob portion 8. The two thin-walled portions 13 are interposed therebetween.

The bellows portion 16 has a V-shaped configuration in which a part of the sealing tube portion 3 is narrowed into a thin plate shape, and is configured in a direction in which the sealing tube portion 3 is contracted in the circumferential direction (that is, the diameter is reduced) (two points in FIG. 7). (See the bellows part 16 indicated by a chain line) and in the circumferentially expanding (that is, diameter expanding) direction (see the bellows part 16 indicated by a solid line in FIG. 7). Therefore, when releasing the mold in the manufacturing process of the bottle cap 1 or when plugging the bottle spout 21 into the bottle spout 21, the shock applied to the second thin wall portion 13, which is the weakened portion, can be buffered. I can do it. Thereby, it is possible to effectively prevent the second thin portion 13 from breaking.

Further, in the bottle mouth cap 1 according to the third embodiment, a crease portion 17 is formed in the knob portion 8 . In this embodiment, the fold part 17 includes a first fold part 17a formed in the horizontal direction (opening direction) from the end of the knob part 8 on the notch part 10 side, and a window continuous to the first fold part 17a. A second fold part 17b is formed in the vertical direction (axial direction) up to the lower end part 7b of the hole 7, and a second fold part 17b is formed in an oblique direction toward the lower end part of the knob part 8, continuing from the upper end part of the second fold part 17b. The third fold portion 17c is formed by three folds.

The protrusion 8a protruding from the inner peripheral surface of the knob 8 allows the knob 8 to easily deform or bend along the crease 17 when the knob 8 is bent and deformed radially outward. Therefore, a larger gap S can be formed between the outer circumferential surface of the bottle mouth part 21 and the inner circumferential surface of the deformed knob part 8, and the knob part 8 can be made easier to pick.

In addition, in this embodiment, the fold part 17 is comprised of three continuous folds, the first fold part 17a, the second fold part 17b, and the third fold part 17c, but in the present invention, However, the crease portion 17 may have any shape as long as it is a shape that allows the knob portion 8 to be easily deformed or folded back toward the outside in the radial direction. Further, the fold 17 has a thin shape that can be deformed, and the configuration of the first to third folds (17a, 17b, 17c) serves as a mark (arrow) indicating the direction in which the knob 8 is pulled.

Another configuration of the third embodiment shown in FIG. 8 is a configuration in which a W-shaped bellows portion 16 is provided instead of the V-shaped bellows portion 16. This W-shaped bellows portion 16 is also elastically deformable in the direction of decreasing and expanding the diameter of the sealing cylinder portion 3. Therefore, it is possible to buffer the impact applied to the second thin wall portion 13, which is the weakened portion, when releasing the mold or plugging the bottle into the mouth portion 21, and more effectively prevents the second thin wall portion 13 from breaking. can be prevented.

FIG. 9(A) is a front view showing the main parts of a container with a bottle spout cap as a fourth embodiment of the present invention, and FIG. 9(B) is a cross-sectional view taken along line AA in FIG. 9(A). be.
The main difference between the bottle opening cap 1 shown in the fourth embodiment and the third embodiment described above is that a thin plate piece 18 is formed as an elastic deformation part in the sealing cylinder part 3, and other structures and Since the functions are the same as those of the third embodiment, the following explanation will focus on the points that are different from the third embodiment, and the same members will be described with the same reference numerals.

In the fourth embodiment shown in FIGS. 9(A) and 9(B), a thin plate piece 18 formed by thinning a part of the sealing cylinder part 3 is placed as an elastic deformation part at a position facing the knob part 8. It is provided via the second thin portion 13.

The thin plate piece 18 is a thin thin plate that protrudes outward in an arch shape, and can be elastically deformed in the direction of reducing or expanding the diameter of the sealing cylinder portion 3. Therefore, when the bottle spout cap 1 is released from the mold or when the bottle spout 21 is capped, the impact applied to the second thin wall portion 13, which is the weakened portion, can be buffered. Thereby, it is possible to effectively prevent the second thin portion 13 from breaking.

Although the structure of the present invention and its effects have been described above with reference to Examples, the embodiments of the present invention are not limited to the above-mentioned Examples.

For example, in the above embodiment, the upper lid part 2, the sealing cylinder part 3, and the stopper part 4 are integrally made of synthetic resin. Alternatively, the stopper body portion 4 may be formed as a separate member. For example, the upper lid part 2 and the sealing cylinder part 3 may be made of metal such as aluminum, and the stopper part 4 may be made of synthetic resin or cork.

The present invention can be applied to a wider range of applications in the field of containers with caps for bottle openings.
