It is a figure which shows the state which has displaced the double container from the state of FIG.

  Hereinafter, the present invention will be described more specifically with reference to the drawings. In this specification, claims, and abstract, “upper” means the side where the pouring cap is positioned with respect to the outer layer body when the double container is placed on a horizontal surface (upright posture). And “below” is the opposite side.

  In FIG. 1, the symbol A shows one embodiment of a double container according to the present invention. The double container A includes an inner layer body 10 that contains the content liquid and an outer layer body 20 that houses the inner layer body 10 inside. A measuring member 30, a check valve 40, a pouring tap 50, and an overcap 60 are provided above the outer layer body 20.

  The inner layer body 10 includes a filling space S for containing the content liquid therein. The inner layer body 10 is made of a thin synthetic resin and can be deformed by volume reduction.

  The outer layer body 20 has flexibility, and has a circular bottom portion 21, and a body portion 22 that extends from the outer edge portion of the bottom portion 21 with substantially the same diameter upward and then contracts in diameter. A cylindrical mouth portion 23 connected to the upper portion of the body portion 22 is integrally connected. The mouth part 23 is provided with an upper opening 23a, and an outward projection 23b extending along the circumferential direction (which may be annular or intermittent) on the outer peripheral surface of the mouth part 23.

The outside air introduction hole may be provided in any of the bottom portion 21, the body portion 22, and the mouth portion 23. In addition, air can be introduced between the inner layer body 10 and the outer layer body 20 in the outside air introduction hole, and a check valve for preventing the outflow of air from each other may be provided. In addition, when providing the outside air introduction hole in the bottom portion 21 of the outer layer body 20, the inner layer bodies 10 are bonded to each other at the rib (pinch-off portion) on the parting line formed at the time of molding, and the outer layer bodies 20 are not bonded to each other. When the parting line is pushed from the outside, the outer layer body 20 is easily cracked to form a slit. Thereby, outside air can be sucked into the outer layer body 20 and the inner layer body 10 from the slit.

  In this embodiment, the inner layer body 10 and the outer layer body 20 are obtained by laminating synthetic resins having low compatibility with each other so as to be peelable, and blow molding a parison formed by laminating these synthetic resin materials. It was obtained by. In addition to blow molding, a preform formed into a test tube is biaxially stretch blow molded, or an outer layer body and an inner layer body are individually formed, and then the inner layer body is mounted in the outer layer body. It may be used. Although not shown, one or a plurality of adhesive bands that extend in the vertical direction between the inner layer body 10 and the outer layer body 20 and partially join the inner layer body 10 and the outer layer body 20 to each other. May be provided.

  The measuring member 30 includes a partition wall 31 that covers the upper opening 23a. The partition wall 31 of the present embodiment has a shape protruding downward. An annular portion 31a extending downward is provided on the lower surface of the central portion of the partition wall 31, and a communication port 32 connected to the filling space S is provided on the inner peripheral side of the annular portion 31a. Further, the communication port 32 is provided with a plurality of ribs 31b arranged at intervals in the circumferential direction.

  A cylindrical tubular wall 33 extending upward is integrally connected to the upper portion of the partition wall 31. On the outer peripheral surface of the cylindrical wall 33, a male screw portion 33a for holding the overcap 60 is provided. Here, the space surrounded by the partition wall 31 and the cylindrical wall 33 functions as a measuring chamber K in which the content liquid can be measured by storing the content liquid in the filling space S through the communication port 32.

  A cylindrical mounting cylinder 34 that surrounds the mouth 23 in the circumferential direction is integrally connected to the upper portion of the partition wall 31. An inward projection 34 a that engages with the outward projection 23 b is provided on the inner peripheral surface of the mounting cylinder 34, and the measuring member 30 is mounted on the mouth portion 23 by a stopper. The measuring member 30 may be attached with screws instead of the outward projections 23b and the inward projections 34a. In this case, it is preferable that the screw for holding the measuring member 30 and the screw for holding the overcap 60 (a male screw portion 33a and a female screw portion 62a described later) have a reverse screw relationship. Further, it is preferable to provide a detent mechanism so that the measuring member 30 does not rotate with respect to the outer layer body 20.

  The measuring member 30 is such that at least the whole or a part of the cylindrical wall 33 is transparent or translucent so that the level of the content liquid introduced into the measuring chamber K can be visually recognized. The cylindrical wall 33 is preferably provided with a scale so that the amount of the content liquid can be confirmed according to the level of the content liquid.

  The check valve 40 has a support portion 41 that is inserted into the communication port 32. Since the lower part of the support part 41 bulges outward in the radial direction, the support part 41 engages with the rib 31b and is retained. In addition, a disc-shaped valve body portion 42 extending toward the radially outer side is provided on the upper portion of the support portion 41. The valve body portion 42 abuts on the upper surface of the partition wall 31 and closes the communication port 32 in a state where the support portion 41 is engaged with the rib 31b. This prevents outside air from entering the filling space S. In addition, if the internal pressure of the filling space S increases, the valve body 42 is separated from the partition wall 31 and opens the communication port 32.

  The spout 50 is attached to the upper part of the cylindrical wall 33. The spout 50 includes an annular fitting wall 51 held on the inner peripheral surface of the cylindrical wall 33, a disk-like upper wall 52 that is integrally connected to the fitting wall 51, and a central portion of the upper wall 52. And a pouring tube 54 that surrounds the pouring port 53 and stands up and has an upper end curved radially outward to form a lip.

  The overcap 60 includes a disk-shaped top wall 61 and an outer peripheral wall 62 that is integrally connected to the outer edge of the top wall 61. Further, a female screw part 62 a corresponding to the male screw part 33 a is provided on the inner peripheral surface of the outer peripheral wall 62, and the overcap 60 is detachably held by the measuring member 30. In order to hold the overcap 60, an undercut may be provided instead of these screw portions.

  In order to measure the content liquid with the double container A configured in this way, after removing the overcap 60, the outer layer body 20 is pressed in a state where the double container A is in the upright posture as shown in FIG. To do. Thereby, since the inner layer body 10 is pressed directly from the outer layer body 20 or via the air between the inner layer body 10 and the outer layer body 20, the filling space S is pressurized. Then, the pressurized content liquid pushes up the valve body 42, and the valve body 42 is separated from the partition wall 31. Accordingly, the content liquid in the filling space S is introduced into the measuring chamber K through the gaps between the communication port 32 and the plurality of ribs 31b. When the pressure on the outer layer body 20 is released and the filling space S returns to the original pressure, the valve body portion 42 immediately sits on the partition wall 31 and the inflow of the content liquid into the measuring chamber K is stopped. For this reason, the amount of the content liquid measured in the measurement chamber K can be finely adjusted by repeating the pressing to the outer layer body 20 and the release thereof. In addition, after releasing the press to the outer layer body 20, the outer layer body 20 tries to return to the original shape with its own restoring force. At this time, since air is taken in between the inner layer body 10 and the outer layer body 20 from an outside air introduction hole (not shown), the outer layer body 20 is restored while only the inner layer body 10 is subjected to volume reduction deformation.

  Then, after measuring the desired amount, the double container A is displaced to the tilted posture as shown in FIG. As a result, the entire liquid in the measuring chamber K can be poured out through the spout 53 and the pour cylinder 54.

  When it is not necessary to measure the content liquid, the outer layer body 20 is pressed in a state where the double container A is in an inclined posture. In this case, since the content liquid in the filling space S is not stored in the measuring chamber K but is directly poured out from the dispensing cylinder 54, an appropriate amount of the content liquid can be poured out while the outer layer body 20 is being pressed. it can.

  Next, another embodiment of the double container according to the present invention will be described with reference to FIGS. In FIG. 4, the symbol B shows another embodiment of the double container according to the present invention.

  Further, the outer layer body 120 includes a bottom portion 121 formed in a raised bottom shape, a body portion 122 having a substantially cylindrical shape with a reduced diameter at the top portion, and a mouth portion 123 having a smaller diameter than the body portion 122. I have. The mouth portion 123 includes an upper opening 123a on the radially inner side. In addition, a cylindrical upper peripheral wall 124 that extends upward and has a diameter larger than that of the mouth portion 123 is provided on the upper portion of the mouth portion 123. Here, a shrink film F is provided on the outer peripheral surface of the outer layer body 120 so as to cover the body portion 122 and the mouth portion 123. In addition, the shrink film F is provided arbitrarily. The inner layer body 110 is provided over the entire inner surface of the outer layer body 120 (from the bottom 121 to the upper opening of the upper peripheral wall 124).

  The inner plug 130 includes a partition wall 131 having a disk shape. A communication port 132 connected to the filling space S is provided at the center of the partition wall 131. An annular wall 133 that extends upward is connected to the outer edge of the partition wall 131, and a flange portion 134 that extends radially outward is provided at the top of the annular wall 133. The annular wall 133 is fitted and held in the mouth portion 123 so as to sandwich the inner layer body 110 in the upper opening 123a.

  Here, the space surrounded by the partition wall 131 and the upper peripheral wall 124 functions as a measuring chamber K in which the content liquid can be measured. At least the whole or a part of the upper peripheral wall 124 is transparent or translucent so that the liquid level of the content liquid can be visually recognized. Further, similarly to the cylindrical wall 33, it is preferable to provide a scale on the upper peripheral wall 124.

  The check valve 140 is formed by connecting an annular base 141 and a disc-shaped valve body 142 with three elastic pieces 143 in the present embodiment, and forms a so-called three-point valve. It is. In addition, various things, such as a 1 point valve and a 2 point valve, are employable. The base 141 is fitted and held on the inner peripheral surface of the annular wall 133. The valve body 142 is seated on the upper surface of the partition wall 131 so as to cover the communication port 132.

  The dispensing cap 150 includes a sealing wall 151 that covers the upper opening of the upper peripheral wall 124 and closes the measuring chamber K, and a base 152 that surrounds the upper peripheral wall 124 in the circumferential direction and is fitted and held on the upper peripheral wall 124.
