  The top wall 7 that is continuous with the upper end of the side wall 6 is composed of a peripheral pressed portion 8, a thin connecting portion 9, and a central pressing portion 10. The peripheral thick part 8 is located on the outer peripheral side of the top wall 7 and extends inward in the radial direction from the upper end of the side wall 6, but its length is short. The thin connecting portion 9 is formed thinner than the peripheral thick portion 8 and includes an annular wall 21, an action base portion 22, and an inversion portion 23 toward the inner (center) side. The annular wall 21 is connected to the inside of the thick peripheral wall portion 8 and extends downward to be disposed at a slight distance from the side wall 6 so that the wall thickness decreases from the upper end side toward the lower end. . The lower end of the annular wall 21 is connected to the action base 22, and the action base 22 is an annular bottom formed so as to extend slightly inward in the radial direction of the extraction tool 1 in the initial state.

The inner peripheral end of the action base portion 22 is connected to the reversing portion 23. The reversing portion 23 extends in a conical cylinder shape from the action base portion 22 to the inside and upward at a relatively large angle, and forms an inflection point 23a at the intermediate portion. .
The inner end of the working base portion 22 is connected to the central pressing portion 10. The central pressing portion 10 is a circular plate member. When the thin connecting portion 9 applies a downward pressing force to the central pressing portion 10, the entire opening device 3 can be positioned at the lower position from the state shown in FIGS. 4 and 5 to the state shown in FIGS. 6 and 7. That is, when the central pressing portion 10 is pressed, the action base 22 is started by the deformation action of the resin, and the reversing portion 23 can be reversed and bent. Therefore, the opening tool 3 can move forward from the raised position in the initial state to the lower position.

An opening tool 3 is provided on the bottom surface 10 a of the central pressing portion 10. The opening tool 3 includes a main part 17, a cutting auxiliary part 18, a diameter expansion auxiliary part 19, and a cutting part 20.
The main portion 17 has a column shape and is formed so as to hang from the center portion of the central pressing portion 10, and a cutting portion 20 formed so that the tip is pointed in a conical shape is formed at the lower end portion. The cutting assisting part 18 extends radially from the outer peripheral part of the main part 17 in a wing shape in four directions (intervals of 90 degrees in the circumferential direction) with reference to the center line of the main part 17. The cutting assisting portion 18 extends in the radial direction to the outer peripheral end of the bottom surface 10a of the central pressing portion 10, and in the vertical direction, the upper end position of the cutting portion 20 from the bottom surface 10a downward, that is, the substantially proximal end side of the conical shape. Extends to position.

The diameter expansion assisting portion 19 extends radially from the outer peripheral portion of the main portion 17 in a wing shape in four directions (intervals of 90 degrees in the circumferential direction) with respect to the center line, and is disposed at an intermediate position between adjacent cutting assisting portions 18. Has been. Therefore, the adjacent cutting assisting portions 18 are arranged at 45 ° intervals in the circumferential direction. The diameter expansion assisting portion 19 extends to the vicinity of the outer peripheral end of the bottom surface 10a of the central pressing portion 10 in the radial direction, and is formed to be shorter than the length of the cutting assisting portion 18 downward from the bottom surface 10a in the vertical direction. .
On the lower tip side of the cutting assisting portion 18, enlarged diameter portions 18 a and 18 b that are inclined upward from the center O side are formed. The enlarged diameter portion 18a on the distal end side is formed so as to be inclined more gently than the enlarged diameter portion 18b located on the upper side.
On the distal end side of the diameter expansion assisting portion 19, a diameter expansion portion 19 a that is inclined upward and outward from the center O side is formed. The inclination of the enlarged diameter portion 19a is formed so that the inclination becomes gentler than that of the enlarged diameter portions 18a and 18b of the cutting assisting portion 18.

The side portions 18c and 19b of the cutting assisting portion 18 and the diameter expansion assisting portion 19 are parallel to the center line O of the main portion 17, and the lengths in the radial direction from the center line O to the side portions are formed to have the same size. Has been.
The lengths of the side portions 18c and 19b in the vertical direction are such that when the reversing portion 23 of the opening device 3 is reversed and the opening device 3 is in the lower position, the lower ends of the side portions 18c and 19b are lower than the interior material 14. The length to be positioned, in other words, the positions of the enlarged diameter portions 18 a, 18 b and 19 a are set to be lower than the interior material 14.
A blocking sheet 16 is attached to the upper surface of the peripheral thick part 8 of the top wall 7 to cover the thin connecting part 9 and the central pressing part 10.

Next, the effect | action of the extraction tool with an opening tool of this embodiment is demonstrated.
When using the dispensing tool 1 with an opening tool, the closing sheet 16 is peeled off, or the central pressing portion 10 is pressed downward from above the closing sheet 16. The closing sheet 16 plays a role in preventing mischief, and if the closing sheet 16 is not damaged, it is confirmed that the sealing state of the container body 12 is maintained without the opening device 3 being lowered. Is done. Note that the closing sheet 16 may be easily broken by forming a weakened portion such as a perforation on the inner peripheral side slightly from the position where the closing sheet 16 is attached to the peripheral thick portion 8. If it does so, operation at the time of pressing down central pressing part 10 from the upper part of closure sheet 16 will become easy.

When the central pressing part 10 is pressed, a force acts on the reversing part 23 that supports the central pressing part 10, and a force that reverses the reversing part 23 downwards acts. Since the action base 22 is provided at the lower end of the annular wall 21, it can be an action starting point where the reversing part 23 is reversed without moving further downward. Therefore, the inversion part 23 is inverted below the action base part 22 by the deformation force of the resin, and the opening tool 3 can be moved downward.
By pushing down the central pressing portion 10, the blocking portion 14 a of the interior material 14 covering the opening 15 a of the exterior material 15 is expanded.
In the opening tool 3, the cutting part 20 having a sharp tip initially breaks through the blocking part 14a, and then the blocking parts in the order of the enlarged diameter parts 18a and 18b of the cutting assisting part 18 as the opening tool 3 moves downward. The breakage of 14a is advanced and expanded, and the enlarged diameter portion 19a of the enlarged diameter auxiliary portion 19 pushes the closed portion 14a behind the cutting auxiliary portions 18a and 18b.

Although the portion where the opening 15a is formed is not visible to the user, since the tip of the cutting portion 20 is located immediately above the opening 15a, the cutting portion 20 can be removed by simply pushing the central pressing portion 10 downward. The blocking portion 14a can be pierced, and a portion corresponding to the opening 15a of the blocking portion 14a is broken.
Thus, when breaking the closing part 14a, it breaks through by the pressing force of the user, but after breaking through the closing part 14a, the reversing force (tensioning force) of the reversing part 23, the cutting assisting part 18 and the diameter expanding assisting part The side portion 18c and the side portion 19b of the 19 are in close contact with the peripheral portion of the opening 15a, or the exterior material 15 is further broken from the peripheral portion of the opening 15a, and the leading end of the opening tool 3 is inserted into the opening 15a. Can be held in.

When the beverage is poured out, the lid member 26 is opened. As described above, the lid member 26 is positioned upward after being opened by the elastic force of the hinge 27 and the like so as not to return by gravity, so as not to prevent the beverage from flowing out.
As shown in FIG. 8, the beverage is poured out by inclining the container body 12 so that the spout 25 faces downward. The circular spout 25 is formed in the range from substantially the upper end to the lower end of the side wall 6 of the pouring tool 1, and can allow the beverage to flow out satisfactorily.
In particular, the lower end side of the spout 25 is formed with the spout 25 formed by leaving only the thickness of the base 5 which is the welded portion of the container body 12 and the thickness of the spout 25 and making them close to each other. A large amount of beverage can be dispensed simply by tilting. Further, the spout 25 is flush with or substantially flush with the side surface 12a of the container body 12, and the length from the edge of the opening 15a to the spout 25 is the horizontal length between the peripheral thick part 8 and the thin connecting part 9. Therefore, the length from the edge part of the opening tool 3 to the side part 12b of the container main body 12 can be shortened, and a drink can be poured out only by tilting the container main body 12 a little.

As described above, when the beverage is allowed to flow out, the remaining broken piece 14a in which the closed portion 14a of the interior material 14 still remaining at the periphery of the opening 15a is cut is formed between the enlarged diameter portions 18a, 18b, and 19a. It is conceivable to try to close the gap.
In the present embodiment, since the side portions 18c and 19b of the cutting assisting portion 18 and the diameter expansion assisting portion 19 bite into the edge of the opening 15a, the remaining broken fragments 14 are restricted from facing inward, and the diameter expanding portion 18a. , 18b, 19a can be prevented from being blocked. Further, since the tip of the opening device 3 protrudes from the opening 15a, even if the residual broken piece 14b attempts to block the enlarged diameter portions 18a, 18b, 19a, the length (including the enlarged diameter portions 18a and 19a) ( The ridge line) is longer than the length of the residual broken piece 14b, and the flow path is not completely blocked.
Further, since the flow path is between the blades of the cutting assisting portion 18 and the diameter expansion assisting portion 19, a total of eight flow passages are formed, and the flow passage on the outlet 25 side (lower side) is mainly used. The flow path on the opposite side (upper side) from the spout 25 is an air inflow port, and the air replacement property is good and the flow rate of the beverage can be increased.
After the desired amount of beverage has flowed out, the lid member 26 can be closed to close the spout 25 for the next use.

Next, 2nd Embodiment in the outflow tool with an opening tool of this invention is described. In addition, in this embodiment, since it differs with respect to the extraction tool with an opening tool of the said 1st Embodiment about the opening tool 3, and other components are the same, only an opening tool is demonstrated.
As shown in FIGS. 9 to 11, an opening tool 31 is provided on the bottom surface 10 a of the central pressing portion 10 of the dispensing tool 1. The unsealing tool 31 is provided with a main portion 32 having a shape in which a cylindrical portion or a prismatic portion is cut out, and the main portion 32 has a cutout portion 33 cut out in the vertical direction on the side where the spout portion 24 is formed. In the present embodiment, the notch 33 is opened so as to be opened approximately 90 degrees in the circumferential direction of the main portion 32, and the cross-sectional shape of the main portion 32 is formed in an arc shape.

The front end of the main portion 32 is formed in a shape that is cut obliquely, and the main portion 32 is formed to be inclined so that the side away from the lid member 26 is long and the portion close to the lid member 26 is short. The inclined part is a cutting blade 34. The cutting blade 34 is disposed immediately above the opening 15a formed in the exterior material 15 of the container body 12. The size of the arc shape of the main portion 32 is that the radius of the opening 15a is substantially the same as the radius of the arc of the main portion 32. It is formed slightly smaller.
A locking projection 35 extending in the arc direction along the outer peripheral surface is formed at an intermediate portion in the vertical direction of the main portion 32, and protrudes in a semicircular shape from the outer peripheral surface. In this embodiment, the locking protrusions 35 are continuously formed in a semicircular shape, but a plurality of locking protrusions 35 may be formed in the circumferential direction at the same height position. As shown in FIG. 11, the height at which the locking protrusion 35 is formed is such that when the reversing portion 23 of the dispensing tool 1 is reversed and the opening tool 31 is in the lower position, the locking protrusion 35 is on the lower surface of the exterior material 15. It is formed in the length located in. In other words, when the opening tool 3 is in the lowered position, the locking projection 35 is formed so as to get over the opening 15a.

Next, the operation of the second embodiment will be described.
When the user pours out the beverage, the container body 12 is tilted so that the lid member 26 is opened and the spout 25 is directed downward.
In the present embodiment, the tip of the opening tool 31 is located on the side away from the lid member 26, and the portion near the lid member 26 is located on the upper end side of the slope. Therefore, the closing portion 14a is cut at the distal end side away from the lid member 26, and the remaining cut piece 14b is connected to the side closer to the lid member 26 side as shown in FIG. Therefore, when the beverage is allowed to flow out by tilting the container body 12, the tip of the residual cut piece 14b faces downward when the beverage passes through the main portion 32, and when there is a flow of the beverage, it is pushed back to the side wall 12a.

In addition, since the tip of the opening tool 31 protrudes from the opening 15a, the length of the cutting blade 34 in the inclination direction is the residual breakage even if the residual broken piece 14b attempts to block the inflow port 36. It is sufficiently longer than the length of the fragment 14b and is not completely blocked.
In addition, since the beverage flows out from the spout 25 through the notch 33 from the inside of the container body 12, it does not pass through the pipe-shaped portion blocked in a cylindrical shape, has good air replacement, and reduces the outflow amount. Can do a lot.
Since the locking projection 35 is formed on the outer peripheral portion of the main portion 32, the main portion 32 is held in the opening 15a, and the opening tool 31 can be stably held in the lowered position.

The present invention has been described in detail based on the embodiments with reference to the accompanying drawings. However, the present invention is not limited to the above-described embodiments, and other modifications can be made without departing from the scope of the present invention. Or it can be changed.
Although the shape of the spout part 24 and the spout 25 is circular in consideration of sealing performance in this embodiment, it may be formed in a quadrangle. The lid member 26 is connected to the hinge 27, but the lid member 26 may be a separate member without being integrated with the pouring tool 1.
