Description

The present invention relates to a container with a lid.

The inner stopper is usually fitted into the mouth and neck of the container body by stoppering, but when filling the stopper, the liquid filled in the container jumps and jumps out of the outlet of the inner stopper. The outlet has been closed before. As a means for closing, for example, as shown in FIG. 3, before the inner plug 202 is plugged into the mouth and neck portion 201 of the container body 200, the inner cap 204 is screwed into the inner plug dispensing cylinder 203. In addition, it is known that the overcap 205 is fitted to the container body 200 at the time of shipment, or the lower end of the peripheral wall of the inner plug fitted into the container body neck is closed with a press breakable closing plate. (Patent Document 1).

Hereinafter, the present invention will be described with reference to embodiments shown in the drawings.
Reference numeral 1 denotes a container, and a first protrusion 3 is provided around the upper outer surface of the body 2. Further, the mouth and neck portion 5 stands from the upper end of the trunk portion 2 via the shoulder portion 4. A second protrusion 6 is provided on the outer surface of the mouth and neck portion 5, and a third protrusion 7 is provided on the outer surface of the mouth and neck portion above the second protrusion 6.

  Reference numeral 10 denotes an inner plug, and a step portion 12 is provided around the inner surface of the lower end of the outer tube 11 fitted to the outer surface of the mouth neck portion 5 portion above the second protrusion 6, and the step portion 12 is provided in the third protrusion. It is fitted to the underside of the strip 7.

  A first inward flange 13 is attached to the upper end of the outer cylinder 11, and an inner cylinder 14 is provided through the inner periphery of the first inward flange 13. The lower part of the inner cylinder 14 is in contact with the inner surface of the upper part of the mouth / neck part 5, and a male screw 15 is formed on the outer surface of the upper part of the inner cylinder 14.

  From the upper end of the inner cylinder 14, a pouring cylinder 17 that constitutes a pouring outlet is erected via the second inward flange 16. The thus configured inner plug 10 is fitted into the mouth-and-neck portion 5 by a stopper. At that time, the stepped portion 12 forcibly gets over the third protrusion 7 and is fitted to the lower surface thereof.

  Reference numeral 20 denotes a transition plug, which is placed on the upper surface of the extraction cylinder 17 on the upper end of the bottomed peripheral wall 21 fitted to the upper inner surface of the extraction cylinder 17 and is provided with an outward flange 23. On the inner peripheral surface of the peripheral wall 21, a groove made of a concave portion constituting the first engagement portion 22 is provided. Further, the upper outer surface of the peripheral wall 21 is formed in a large outer diameter portion, and the large outer diameter portion is in close contact with the upper inner surface of the extraction tube 17.

  Reference numeral 30 denotes an overcap that hangs the inner and outer double cylinders 32 and 33 having different heights from the peripheral edge of the top surface 31 so that the lower end of the outer cylinder 33 is placed on the first protrusion 3 and on the inner surface of the inner cylinder 32. The formed female screw 34 is screwed into the male screw 15.

A fitting cylinder 35 having a bottom opening is suspended from the central portion of the top surface 31 into the peripheral wall 21 of the transition plug. On the outer peripheral surface of the fitting cylinder 35, a second engaging portion 36 constituted by a convex portion that engages with the first engaging portion 22 is provided.

Next, the operation will be described.
Before plugging into the container 1, the transition stopper 20 is fitted into the dispensing cylinder 17 of the inner stopper 10 to form the container stopper. The inside plug of the container thus obtained is plugged into the mouth / neck portion 5 of the container filled with the liquid.

  Since the inner stopper pipe 17 is closed by the transition stopper 20, even if the container vibrates during the stoppering and the liquid in the container jumps up, it does not jump out of the outlet of the outlet cylinder 17. After the stoppering, the overcap 30 is fitted into the container.

At that time, the fitting cylinder 35 hanging from the top surface 31 is fitted into the transition plug 20, and at the same time, the second engaging portion 36 is engaged with the first engaging portion 22. In this way, the container is shipped with the overcap 30 fitted to the container.

  To open the cap, the overcap may be rotated so that the female screw 34 of the inner cylinder of the overcap 30 is screwed upward from the male screw 15 of the inner plug. Then, the fitting cylinder 35 of the overcap and the transition plug Since the peripheral wall 21 is connected via the first and second engaging portions 23, 36, the transition plug 20 is detached upward from the dispensing cylinder 17 and moves to the overcap 30.

That is, the transition plug 20 is detached from the inner plug 10 and is integrally connected to the overcap 30. In this way, the transition plug 20 is detached from the inner plug dispensing cylinder 17 and moved to the overcap 30 because the overcap 30 and the transition plug are more than the fitting force between the transition plug 20 and the middle plug dispensing cylinder 17. This is because the engaging force with the first and second engaging portions 22, 36 with 20 is stronger.

  In order to close the container after the liquid in the container has been poured out, the overcap 30 may be fitted into the container, and the transition plug 20 integrally connected to the overcap is disposed in the dispensing cylinder 17. As a result of the fitting, the inner tube dispensing cylinder 17 is closed. That is, the transition plug 20 serves as a blocking member for preventing the liquid from splashing when the stopper is plugged, and also serves as a blocking plug when the dispensing tube of the inner plug is not used.

  FIG. 2 shows a second embodiment. In the first embodiment, the fitting cylinder 42 of the overcap 30 is fitted into the peripheral wall 21 of the transition plug, but in this embodiment, the fitting cylinder of the overcap 30 is the outer periphery of the outward flange 40 of the transition plug 20. It differs in that it is fitted to the surface.

  That is, an engagement protrusion as a first engagement portion 41 is provided on the outer peripheral surface of the outward flange 40 of the transition plug 20, while the second engagement is provided on the lower inner surface of the fitting cylinder 42 of the overcap. An engaging projection as a joint portion 43 is provided around, and the engaging projection of the overcap is engaged with the lower surface of the engaging projection of the transition plug.

With this configuration, when the overcap 30 is rotated for opening, the transition plug 20 is pulled out of the middle plug dispensing cylinder 17 and moved to the overcap 30 as in the first embodiment. Since other configurations are the same as those of the first embodiment, the description thereof is omitted.

  FIG. 3 shows a third embodiment. Reference numeral 101 denotes a container, and a male screw portion 104 is formed on the outer surface of the upper end portion of the body portion 102 via an upward stepped portion 103. At the upper end of the male screw portion 104, a mouth and neck portion 106 stands up via a shoulder portion 105. A first protrusion 107 is provided around the outer surface of the mouth and neck portion 106, and a second protrusion 108 is provided around the outer surface of the upper end portion of the mouth and neck portion 106.

  110 is an inner plug, and a fitting portion 112 is provided around the inner surface of the lower end of the outer cylinder 111 fitted to the second protrusion 108, and the fitting portion 112 is in contact with the lower surface of the second protrusion 108. .

  An inward flange 113 is attached to the upper end of the outer cylinder 111, an inner cylinder 114 that hangs from the inner and outer intermediate portions of the inward flange 113 is fitted to the inner surface of the upper end of the mouth and neck portion 106, and the inward flange 113 A pouring cylinder 115 that constitutes the pouring port stands from the inner periphery. The middle portion of the upper portion of the extraction tube 115 is reduced in diameter to be formed in the reduced diameter portion 116, and the first fitting portion 117 is provided around the outer surface of the extraction tube 115 below the reduced diameter portion 116. .

  120 is a transition plug, and a second fitting portion 122 is provided on the inner surface of the lower end inner surface of the top peripheral wall 121 fitted to the upper outer surface of the dispensing cylinder 115, and the second fitting portion 122 is a first fitting portion. 117 is engaged with the lower surface. A third fitting portion 123 is provided around the outer surface of the peripheral wall 121.

  Reference numeral 130 denotes an overcap. The outer peripheral wall 132 is suspended from the peripheral edge of the top surface 131, and a female screw portion 133 formed on the inner surface of the lower end portion of the outer peripheral wall 132 is screwed into the male screw portion 104. A fitting cylinder 134 is fitted from the center of the top surface 131 to the outer surface of the peripheral wall 121 of the transition plug 120. A fourth fitting portion 135 is provided around the inner surface of the lower end portion of the fitting cylinder 134, and the fourth fitting portion 135 is engaged with the lower surface of the third fitting portion 123.

With this configuration, when the overcap 130 is rotated for unsealing, the fitting force between the fitting tube 134 of the overcap 130 and the transition plug 120 is the fit between the transition plug 120 and the dispensing tube 115. Since the resultant force is greater than the resultant force, the transition plug 120 is extracted from the middle plug extraction tube 115 and transferred to the overcap 130 as in the first embodiment.

Next, a method for manufacturing a container having the above configuration will be described.
First, before the inner stopper 10 is plugged into the mouth-and-neck portion 5 of the container filled with the contents, the transition stopper 20 is fitted into the inner stopper dispensing cylinder 17 (first step). Subsequently, the inner stopper 10 fitted with the transition stopper 20 is plugged into the mouth / neck portion 5 of the container (second step).
