Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The draft concerns a cap with an outflow hole.

[0002]

[Prior art]

 A cap is widely used in which a cap with an outflow hole is formed by a cap body having the outflow hole and an auxiliary cap attached to the cap body by opening and closing the outflow hole via a so-called three-point hinge.

[0003]

[Problems to be solved by the device]

 In the above conventional cap, since the auxiliary cap is elastically inverted, the opening and closing of the outflow hole can be ensured, but since the auxiliary cap is formed almost in the same manner as a normal cap, it can be used as a general cap. On the other hand, there are drawbacks that a large amount of molding material is required and the structure is relatively complicated, resulting in high cost.

According to the present invention, the central portion of the top wall of the cap is formed as an elastically reversible ridged portion with a lever and a nozzle, and the ridged portion is elastically flipped up and down by the lever operation, and when rising upward, the nozzle upper end opening is In addition to opening, a lever is provided to close the nozzle opening when the elastic member is depressed downward, and a seal plate that hangs the inlet at the lower end of the nozzle from the top wall of the cap is closed. In addition, it is provided to ensure that the nozzle is sealed tightly.

[0005]

[Means for Solving the Problems]

 The outer peripheral portion of the top wall that hangs the peripheral wall 2 for fitting the neck portion of the container body is formed as a thick-walled flange-shaped portion 3, and the central portion of the top wall surrounded by the flange-shaped portion is formed as an elastically invertible raised portion 5, and the raised portion is formed. Part between the front and rear parts of the inner peripheral edge of the flange-shaped part in a V shape via the first and second hinges 6 and 7, and the inner periphery of the flange-shaped part from both left and right sides of the refractive plate. The elastic thin plates 9 and 9 descending to the left and right edges at substantially the same inclination angle, and the refraction plate 8 is formed by connecting the short plate 10 and the long plate 11 at their respective leading ends through the third hinge 12. In addition, a nozzle 14 that penetrates the short plate is provided, and a lever 15 that elastically reverses the ridge is outwardly protruded from the upper portion of the long plate 11 so that the ridge 5 is elastically inverted downward. The nozzle opening 14a is on the side surface of the intermediate portion of the lever 15, and the lower end inlet 14b of the nozzle 14 is the flange-shaped portion. Sealing plate 17 was Luo vertically is occluded capable respectively.

[0006]

[Action]

 In the state shown in FIGS. 1 and 3, the upper end opening 14a of the nozzle 14 attached to the short plate 10 in a penetrating state is opened to the outside of the cap, and the inlet 14b at the lower end of the nozzle 14 is also opened to the inside of the cap. . When the lever 15 is pushed downward in the drawing from this state, the raised portion 5 is recessed by elastic reversal as shown in FIG. 2, and at this time, the lever 15 is at the nozzle opening 14a and the inlet 14b at the lower end of the lever is at the flange. The seal plate 17 hanging from the shape 3 is closed. In the state shown in FIG. 2, the tip of the lever projects upward and outward from the nozzle opening 14a, and by pushing the tip of the lever to the upper left in the figure, the lever is elastically reversed again as shown in FIG.

[0007]

【Example】

 The cap 1 is integrally formed of a synthetic resin material having excellent flexing and stretching resistance, and has a thick flange-like portion 3 on the outer peripheral portion of the top wall that hangs down the peripheral wall 2 that can be fitted to the outer surface of the neck of the container body. Then, the inner cylinder 4 to be fitted to the outer surface of the mouth / neck portion is hung from the lower surface of the flange portion. The shape of the inner peripheral edge of the flange-shaped portion 3 is determined by the shape of the outer peripheral edge of the raised portion 5 formed by the top wall portion surrounded by the flange-shaped portion.

The raised portion 5 is provided with a refraction plate 8 that is erected in a V shape between the front and rear portions of the inner peripheral edge of the flange-shaped portion through the first and second hinges 6 and 7, and from both left and right sides of the refraction plate. It is formed by elastic thin plates 9 and 9 which descend to the left and right edges of the inner periphery of the flange portion at substantially the same inclination angle. Further, the refraction plate 8 is formed by connecting the respective tip portions of the short plate 10 and the long plate 11 via the third hinge 12. The short plate 10 and the elastic thin plates 9 and 9 may be provided with substantially the same inclination angles, but in this case, a ridge line is formed in the elastic thin plate portion on the side of the connecting portion between the short plate and the long plate. In that case, since the ridgeline has a rib function and makes elastic deformation for elastic reversal difficult, the flange-shaped inner peripheral portions 13, 13 on both left and right sides of the above-mentioned connecting part are circled so that the ridgeline is not formed. The angle of inclination of the elastic thin plates 9 and 9 is adjusted so as to form an arc shape to prevent the occurrence of the ridge line.

A nozzle 14 is attached to the short plate 10 in a penetrating state, and a lever 15 for elastically inverting the raised portion 5 is projected from the upper portion of the long plate 11. The nozzle 14 and the lever 15 are provided so that the opening 14a at the upper end of the nozzle can be closed by the side surface of the intermediate portion of the lever 15 in a state where the ridge 5 is depressed downward as shown in FIG. Therefore, it is advisable to attach a plug-like part 16 to the side surface of the lever. Further, at this time, the lower portion of the lever 15 is laterally arranged so that the lower end inflow port 14b is closed by the seal plate 17 hanging from the flange portion 3. In the example shown in the figure, the central axis of the upper part of the nozzle is provided so as to be orthogonal to the short plate 10 and the end face of the nozzle is parallel to the short plate 10.These are determined by the relationship with the protrusion angle of the lever 15 with respect to the long plate 11. Good.

[0010]

[Effect of device]

 The present invention is configured as described above. When the lever 15 that elastically reverses the ridge is protruded outwardly from the long plate 11 of the ridge 5, and when the ridge is depressed downward, the lever side surface is the nozzle 14. Since the mouth portion 14a is provided so as to be closed, the lever serves as an operation plate for elastically reversing the raised portion and also serves as a lid plate for closing the nozzle opening portion, which simplifies the structure of the cap and further improves the nozzle structure. When the mouth side 14a is closed by the side surface of the lever, the inlet 14b at the lower end of the nozzle is provided so as to be closed by the seal plate 17 that hangs down from the flange-like portion 3. Therefore, the closing is performed twice. You can increase the effect. Furthermore, since the nozzle opening and the inlet 14b are opened and closed by elastic reversal of the raised portion by lever operation, opening and closing can be performed easily and quickly. Furthermore, since the nozzle opening is provided so that the middle portion of the lever side surface is closed, as shown in FIG. 2, the tip of the lever projects above the cap when the opening is closed, thus pushing up the tip. As a result, it becomes easy to invert the upward elasticity of the raised portion 5 performed.
