  Hereinafter, typical embodiments of the present invention will be described with reference to FIGS. The lid device according to this embodiment has a cap 2 and functions to discharge the contents of the container B with the cap 2 mounted on the mouth portion Ba to the outside by a pressing operation of a part of the cap 2. To do. The lid device further includes an inner plug 1 fitted into the mouth portion Ba of the container B, and the cap 2 is mounted on the mouth portion Ba fitted with the inner plug 1. . In this lid device, the space in the container B and the space in the cap 2 are liquid-tightened by the inner plug 1 until a part of the cap 2 (a pressing portion 203d described later) is first pushed in. It comes to classify into. In the lid device, the two spaces are made to communicate with each other by breaking a part of the inner plug 1 (breakable part 131 described later) by the first pushing operation of the cap 2. That is, such a lid device is capable of discharging the contents of the container B to the outside by removing the inner plug 1 from the mouth portion Ba of the container B and performing the first pushing operation of a part of the cap 2. It has a structure that can produce

  In the illustrated example, the container B has a bottle shape in which the mouth portion Ba is formed in a cylindrical shape having a male screw portion Bb on the outer periphery thereof. In the example shown in the drawing, the cap 2 constituting the lid device having the female screw portion 202 corresponding to the male screw portion Bb is screwed into the mouth Ba after the inner plug 1 constituting the lid device is fitted in the mouth portion Ba. By combining, the cap 2 over the mouth portion Ba is mounted. And in the example of illustration, after making the said fracture | rupture by the first pushing operation of a part of cap 2, by pushing in a part of this cap 2 from the state which has the opening Ba of the container B down, The contents (not shown) of the liquid container B are ejected to the outside from a later-described ejection portion 203b of the cap 2.

  The inner plug 1 includes a thin breakable portion 131. In the illustrated example, the inner plug 1 includes a bottomed short tubular portion 10, an outer casing 11 that surrounds the upper opening of the short tubular section 10, and a further lower end from the protruding end of the outer casing 11. The surrounding wall part 12 which protrudes is provided. The outer diameter of the short cylindrical portion 10 of the inner plug 1 is substantially equal to the inner diameter of the mouth portion Ba of the container B. The distance between the short cylindrical portion 10 and the circumferential wall portion 12 is substantially equal to the thickness dimension of the mouth portion Ba of the container B. In the illustrated example, the short cylindrical portion 10 of the inner plug 1 is fitted from the bottom side to the mouth Ba of the container B to a position where the outer casing 11 contacts the edge of the mouth Ba of the container B. Thus, the mouth portion Ba is liquid-tightly closed by the inner plug 1. In this closed state, the circumferential wall 12 is positioned outside the mouth Ba of the container B.

  In this embodiment, the breakable portion 131 is a groove 132 that is formed in the bottom portion 13 of the inner plug 1 that goes around the central axis x of the container B and has a groove start end and a groove end. . In the illustrated example, such a C-shaped groove 132 is formed on the upper surface of the bottom portion 13 of the inner plug 1 to form a thin breakable portion 131 in the inner plug 1. The groove 132 has a non-breakable portion 133 between the groove start end and the groove end, and the link member 203g described later is moved inward of the container B by the pressing operation of the pressing portion 203d. The bottom center portion located inside the breakable portion 131 is pushed by the member 203g, and the bottom center portion and the bottom outer peripheral portion are separated at the breakable portion 131 leaving the unbreakable portion 133. . By configuring the breakable portion 131 in this way, the space in the cap 2 and the space in the container B can be communicated in a wide range at the time of breakage.

  In this embodiment, the inner plug 1 is made of a material having elastic deformation characteristics such as a soft synthetic resin. Then, at least one of the portions of the inner plug 1 that are divided by the breakable portion 131 is elastically returned toward a position where the breakable portion 131 is closed after the breakable portion 131 is broken. In the illustrated example, the non-breakable portion 133 is used as a hinge portion, and when the downward pressing by the linkage member 203g described later is released, the bottom center portion that becomes one of the divided portions is broken by elastic recovery. It returns to the position where the breakable portion 131 is closed, that is, the position where the bottom center portion and the bottom outer peripheral portion are located on the same surface.

  The cap 2 includes a pressing portion 203d that can be pushed into the cap 2 by elastic deformation, and a discharge portion 203b that discharges the contents of the container B when the pressing portion 203d is pressed. In the illustrated example, the cap 2 includes a main body 20 including the pressing portion 203d and the discharge portion 203b, and a cover 21 that releasably covers an upper portion of the main body 20.

  The main body 20 is configured to have a cylindrical shape with the cylinder lower end opened and the cylinder upper end closed. Between the upper end and the lower end of the cylinder of the main body 20, a circumferential step surface 201 is formed inside the main body 20 and facing downward. The inner diameter of the main body 20 is substantially equal to the outer diameter of the mouth portion Ba of the container B below the circumferential step surface 201, and is smaller than the inner diameter of the mouth portion Ba of the container B above the circumferential step surface 201. The female screw portion 202 is formed below the circumferential step surface 201 inside the main body 20. In the illustrated example, the male screw portion formed on the outer periphery of the mouth portion Ba from the bottom end of the main body 20 to the inside of the main body 20 from the state in which the inner plug 1 is fitted to the mouth portion Ba of the container B as described above. The mouth portion Ba is accommodated by screwing the female thread portion 202 of the main body 20 into Bb. At the end position of the screwing, the circumferential step surface 201 is in close contact with the outer casing 11 of the inner stopper 1 and sandwiches the outer casing 11 with the edge Bc of the mouth portion Ba of the container B. Thereby, in this position, the space in the cap 2 and the outside are separated liquid-tightly.

  A head portion 203 having a discharge portion 203b and a pressing portion 203d is formed above the circumferential step surface 201 in the main body 20. The head part 203 has a base part 203a and a pressing part 203d above the base part 203a. A discharge pipe 203c is provided on the side of the base 203a so as to protrude laterally from the side and communicate with the inside and outside of the base 203a. The discharge pipe 203c functions as the discharge section 203b. The pressing portion 203d is configured to have a short cylindrical shape whose outer diameter is smaller than the outer diameter of the base portion 203a and whose upper end of the cylinder is closed by the disk-like operation portion 203e. The lower end of the cylinder of the pressing portion 203d and the upper portion of the base portion 203a are connected by an elastically deformable portion 203f that is thin. As a result, a pressing operation can be performed with the upper portion of the pressing portion 203d facing inward of the cap 2, and when the pressing operation is stopped, the pressing portion 203d is returned to the position before the pressing operation. .

  In the example shown in the figure, the cover 21 is configured to have a cap-like shape having a size for accommodating the head portion 203 of the main body 20 inside. Reference numeral 22 in the figure denotes a hinge part for connecting the cover 21 and the main body 20, and by elastically deforming the hinge part 22, the cover 21 exposes the position where the head part 203 of the main body 20 is covered. It is designed to rotate between the unfolded position.

  Between the cap 2 and the inner plug 1, there is provided a linking member 203g that moves inward of the container B by a pressing operation of the pressing portion 203d. Then, the breakable portion 131 is broken by the linkage member 203g moved at the time of the first pushing operation of the pressing portion 203d so that the space in the container B and the space in the cap 2 are communicated. .

  In the illustrated example, the link member 203g has an upper end integrally connected to the inner surface of the disk-like operation portion 203e of the pressing portion 203d, and hangs down from the inner surface of the bottom portion 13 of the inner plug 1 by hanging down from the inner surface. The long body 203h is in contact with the rod, and in the illustrated example, it is configured as a rod-shaped body. By configuring the linking member 203g in this manner, the linking member 203g does not interfere with the pushing operation of the pressing portion 203d of the cap 2, and the required rigidity can be imparted to the linking member 203g. . In the example shown in the drawing, such a rod-like body is slightly flat in a cross section perpendicular to the length direction, and has a wide side and a narrow side. The dimension between the upper end and the lower end of the rod-like body is approximately the distance between the disc-like operation portion 203e of the pressing portion 203d and the bottom center portion of the bottom portion 13 of the inner plug 1 before the pushing operation. Match.

  Before the first pushing operation of the pressing portion 203d of the cap 2, the space in the container B and the space in the cap 2 are separated by the inner plug 1, and the contents of the container B are externally discharged from the discharge portion 203b of the cap 2. Is not discharged. When the cap 2 is pushed in for the first time, the link member 203g moved toward the inside of the container B presses a part of the inner plug 1, that is, the bottom center portion of the bottom portion 13 in the illustrated example, to cause the breakage. The possible part 131 can be broken. Then, the space in the container B and the space in the cap 2 can be communicated with each other through the breakable portion thus broken by one touch without using the function of the pressing portion 203d without removing the inner plug 1. After such two spaces are communicated with each other, the pressing portion 203d is pushed in from the state where the mouth portion Ba of the container B is down, so that the pressure on the container B side is increased and the content from the discharge portion 203b is increased. An object can be discharged. The lid device according to the illustrated example is typically configured to be used for closing the mouth portion Ba of the liquid container B having viscosity such as ra oil.

 In this embodiment, at least one of the portions of the inner plug 1 that is divided by the breakable portion 131, in the illustrated example, the bottom central portion of the bottom portion 13 of the inner plug 1 is broken by the breakable portion 131. Since this is elastically returned to a position where it is closed later, the space in the container B and the space in the cap 2 are communicated with each other using the function of the pressing portion 203d. A valve function can be provided, and the contents of the container B do not enter the cap 2 as much as possible unless the pressing portion 203d of the container B is pushed in.

  The linkage member 203g may be configured as an elongated body 203h that is provided on the inner plug 1 side and extends in the direction of the central axis x of the container B, as shown in FIG. In this example, the long body 203h has its lower end integrally connected to the bottom center portion of the bottom portion 13 of the inner plug 1, and its upper end is in contact with the inner surface of the disk-like operation portion 203e of the pressing portion 203d. .

  Further, the linkage member 203g may be provided in both the cap 2 and the inner plug 1 as shown in FIG. In the example shown in FIG. 8, the lower end of the elongated body 203 h whose upper end is integrally connected to the inner surface of the disk-like operation portion 203 e of the container B, and the lower central portion of the bottom portion 13 of the inner plug 1 are arranged at the lower end. The upper end of the long body 203 h that is integrally connected is abutted at an intermediate position of the cap 2.

  Although not shown in the drawings, the linking member 203g is configured such that the lower end of the long body 203h whose upper end is integrally connected to the pressing portion 203d of the cap 2 is integrally connected to the bottom 13 of the inner plug 1. It can also be made.

  FIG. 9 shows an example in which the inner plug 1 is provided with a guide portion 134 at the lower end of the linkage member 203 g protruding downward from the pressing portion 203 d of the cap 2. In this example, a circumferential ridge that accommodates the lower end of the linkage member 203g inside is formed in the bottom center portion of the bottom portion 13 of the inner plug 1 so that the guide portion 134 is provided on the inner plug 1 side. In this way, when the pressing portion 203d of the cap 2 is pushed in, the linkage member 203g can always press the predetermined portion of the inner plug 1 downward with a predetermined amount of force. The breakable portion 131 can be appropriately broken by the first pushing operation of the pressing portion 203d.

  In the example described above, the bottom center portion of the bottom portion 13 of the inner stopper 1 is connected to the bottom peripheral portion by the non-breakable portion 133, but the breakable portion 131 is provided without any breaks around the central axis x of the container B. May be. In this case, first, the bottom center portion can be completely separated from the bottom peripheral portion by the first pushing operation of the pressing portion 203d of the cap 2, and secondly, the arrangement of the linking member 203g, etc. By adjusting, it is possible to leave a part of the breakable portion 131 provided without a break as described above without breaking. Although not shown, a plurality of grooves may be provided radially from the center of the bottom central portion of the bottom portion 13 of the inner plug 1, and these grooves may be used as breakable portions 131.

  In the lid device according to this embodiment, it is possible to easily ensure the provision of the characteristic to the portion that should have the elastic deformation property by using the lid device as a synthetic resin molded product.
