  By the way, in such a pouring container, when the container main body is tilted, the contained liquid and the outside air are replaced, and the liquid is poured out. For example, as shown in Patent Document 1 In the case of a small-diameter dispensing cylinder, it is difficult to smoothly replace the content liquid and air, and the content liquid to be dispensed may pulsate and scatter around, leaving a problem in terms of ease of use.

  The objective of this invention exists in the place which proposes the new extraction container which can prevent the pulsation of the content liquid poured out with inclination of a container main body.

The present invention includes a container main body that contains the content liquid and a pouring cap that is attached to the mouth of the container main body, and the content liquid is poured out of the pouring cap by displacing the container main body in a tilted posture. A dispensing container,
The container main body has a volume-removable inner layer body having a content liquid storage space inside thereof, and forms an outer shell of the container main body to house the inner layer body inside and between the inner layer body and the outside world. Consists of an outer layer body with an outside air introduction hole that is always in communication,
The outside air introduction hole is provided at the bottom of the outer layer body,
The pouring cap has a pouring outlet through which the accommodation space and the outside world communicate with each other at the time of pouring,
The inner layer body is deformed and deformed in accordance with the extraction of the content liquid, and the content liquid is extracted without replacement with the outside air. After the content liquid is completely dispensed, the container body is returned to the standing posture. And a pour-out container in which outside air is drawn into the housing space from the pour-out port to restore the inner layer body.

  Here, the “outside air introduction hole in which the (outer layer body) and the inner layer body communicate with each other and the outside world at all times” means that the outside air introduction hole remains open during the dispensing of the content liquid. For example, it is intended that an air check valve for preventing air from escaping from the space between the outer layer body and the inner layer body to the outside is not provided. The same applies to the “outlet where the accommodation space and the outside world are always in communication”, and the outlet remains open while the content liquid is poured out, for example, air enters the inner layer from the outside. It is intended that no liquid check valve is provided to prevent this.

  The pouring cap has a through-hole provided in the top wall covering the mouth portion, and a cap body having the upper opening of the pouring cylinder rising from an edge of the through-opening as the pouring port, and the cap body A lid that is connected via a hinge, and the lid is provided with a seal cylinder that is inserted into the extraction cylinder and closes the extraction cylinder, and a finger hook portion that is disposed opposite to the hinge. It is preferable.

  According to the dispensing container having the above-described configuration, the inner layer body that contains the content liquid can be volume-reduced and deformed, and the volume decreases as the content liquid is dispensed. The liquid can be dispensed and the pulsation of the content liquid is prevented.

  In addition, if the lid of the pouring cap is provided with a seal tube that is inserted into the pouring tube and closes the pouring tube, and a finger hook that is placed opposite the hinge, the liquid content is not intended when not in use. Therefore, it is possible to prevent malfunctions that are poured out, and the lid can be opened with one hand during use, which improves usability.

It is a figure which shows one Embodiment of the extraction container according to this invention, and has shown the extraction container of the standing posture in a partial cross section by side view. It is a figure which shows the state by which the pouring container of FIG. 1 is displaced to a tilting attitude and content liquid is poured out. It is a figure which shows the state which returned the pouring container of FIG. 2 to the standing posture.

  Hereinafter, the present invention will be described more specifically with reference to the drawings. FIG. 1 is a view showing an embodiment of a dispensing container according to the present invention, and shows a partially standing sectional view of a dispensing container in a standing posture. In the present specification, claims, abstract, and drawings, the “up” direction and “down” direction refer to the orientation of the dispensing container in the standing posture.

  In FIG. 1, the code | symbol 1 shows one Embodiment of the extraction container of this invention. The dispensing container 1 includes a container body 10 that stores the content liquid and a dispensing cap 20 that is attached to the mouth of the container body 10. Is provided.

  The container main body 10 includes an inner layer body 11 having a content liquid storage space M that can be reduced in volume, and an outer layer body 12 that forms an outer shell of the container main body 10 and accommodates the inner layer body 11 inside. In the present embodiment, the outer layer body 12 erects the cylindrical body portion 14 from the edge of the circular bottom portion 13, and the shoulder portion 15 that is reduced in diameter toward the radially inner side at the upper portion of the body portion 14. A cylindrical mouth / neck portion 16 serving as a mouth portion of the container body 10 is integrally connected via the. A screw portion 16 a is provided on the outer peripheral surface of the mouth and neck portion 16. Further, although not shown, the outer layer body 12 is provided with a through hole (outside air introduction hole) that constantly communicates with the inner layer body 11 and the outside. Note that the constant communication means that the content liquid in the storage space M is returned to the standing posture again after the content liquid is poured out while the container body 10 in the standing posture is tilted. Means that the outside air introduction hole remains open. For example, a check valve for preventing air from escaping from the space between the inner layer body 11 and the outer layer body 12 to the outside is Intended not to be provided.

  The container body 10 in this embodiment is formed by laminating an inner layer body 11 formed of a thin synthetic resin capable of volume reduction and an outer layer body 12 formed of a synthetic resin having low compatibility with the inner layer body 11. It is obtained by blow molding a parison formed by laminating these synthetic resin materials. The outside air introduction hole is formed by applying a pressing force from the outside to the joint (bottom seal portion) between the inner layer body 11 and the outer layer body 12 formed in the bottom portion 13 of the outer layer body 12 at the time of blow molding. It is formed by a bottom crack-like gap. In addition, the container main body 10 may be such that the inner layer body 11 and the outer layer body 12 are individually formed in advance, and then the inner layer body 11 is mounted in the outer layer body 12. Further, the outside air introduction hole is not limited to the one using the bottom crack-like gap, and a through-hole may be formed in the body part 14 or the mouth neck part 16.

  The dispensing cap 20 includes a cap body 21 that is attached to the mouth and neck portion 16. The cap body 21 has a cylindrical outer peripheral wall 22 that surrounds the mouth-and-neck portion 16, and a screw portion 22 a that engages with the screw portion 16 a of the mouth-and-neck portion 16 is provided on the inner peripheral surface of the outer peripheral wall 22. ing. In order to attach the cap body 21 to the mouth-and-neck portion 16, an undercut may be used instead of these screw portions. Further, a top wall 23 covering the mouth and neck portion 16 is integrally connected to the upper end of the outer peripheral wall 22, and a through opening 23 a is provided at a position shifted radially outward from the central axis O of the container body 10. . Furthermore, a substantially cylindrical pouring cylinder 24 is provided at the edge of the through-opening 23a so as to stand upward and bend its upper end radially outward to form a lip. In the upper part, an upper opening 24a through which the accommodation space M and the outside world communicate with each other is provided as an outlet for the content liquid. Here, the term “continuous communication” means that the upper opening 24a remains open while the content liquid is being dispensed (while the lid 27 is opened), as in the case of the outside air introduction hole described above. It is intended that no liquid check valve or the like is provided between the space M and the upper opening 24a.

  Further, the pouring cap 20 has a hinge 26 integrally connected to the outer peripheral wall 22 of the cap body 21 on the opposite side of the pouring cylinder 24 across the central axis O, and the lid 26 is attached to the hinge 26. They are connected together. The lid body 27 includes an outer wall 28 that is continuous with the outer peripheral wall 22 of the cap body 21, and a top wall 29 that is integrally connected to the upper end of the outer wall 28 and covers the dispensing cylinder 24. A sealing cylinder 29a is provided which is inserted into the dispensing cylinder 24 and comes into liquid-tight contact with the inner peripheral surface thereof. In addition, on the outer wall 28, a finger hooking portion 28 a that is a finger hook when opening the lid 27 is provided on the side opposite to the hinge 26 across the central axis O (a portion facing the hinge 26). .

  When discharging the content liquid from the dispensing container 1 configured as described above, the lid 27 is first opened as shown in FIG. In opening the lid 27, the lid 27 can be opened with one hand by placing the thumb on the finger-hanging portion 28 a, holding the container body 10 with the remaining fingers or palm, and lifting the thumb upward. After that, by displace the pouring container 1 in the tilted posture, the content liquid in the accommodation space M flows through the through opening 23a by its own weight, flows into the inside of the pouring cylinder 24, and is poured from the upper opening 24a. Is issued. Here, since the inner layer body 11 is deformable and deformable, the content liquid is poured out without replacement with the outside air. That is, the pulsation of the content liquid can be prevented even if the dispensing cylinder 24 has a small diameter. Since the outer layer body 12 is provided with an outside air introduction hole (in this embodiment, a bottom crack-like gap not shown), even if the inner layer body 11 undergoes a volume reduction deformation, the inner layer body 11 and the outer layer body Since the outside air enters between each other, the volume reduction deformation of the inner layer body 11 is not hindered.

  When the container body 10 is returned to the original standing posture as shown in FIG. 3 after the dispensing of the content liquid is completed, the content liquid in the storage space M is poured out in accordance with the posture change of the container body 10. Since the fluid flows from the side to the bottom 13 side of the outer layer body 12, the inner layer body 11 that has undergone the volume reduction deformation is restored at this time. As a result, the outside air is drawn into the accommodation space M from the upper opening 24a of the dispensing cylinder 24, so that the residual content liquid adhering to the upper opening 24a is drawn into the inside of the dispensing cylinder 24 together with the outside air (residual content liquid Dripping prevention).

  In addition, when not in use, the lid 27 is closed, so that the seal cylinder 29a comes into liquid-tight contact with the inner peripheral surface of the dispensing cylinder 24. This prevents the liquid from being unintentionally poured out. it can. Further, the operation of closing the lid 27 can be performed with one hand.

  The dispensing container according to the present invention is not limited to the above-described embodiment, and various modifications can be made within the scope according to the claims. In the embodiment described above, a delamination container (so-called delamination container) obtained by blow-molding a laminated parison obtained by extruding an outer layer body and an inner layer body is used, and a bottom crack-like gap or through-hole is formed in the outer layer body. For example, when the outer layer body and the inner layer body are separately formed and then a double container is used in combination, the mouth and neck of the outer layer body and the cap body are used. An air passage (for example, a groove that cuts out the threaded portion of the outer layer body or the cap body or a spiral gap formed between the threaded screw portions) is provided between the outer peripheral wall and the outer layer body. At least one of the mouth and neck of the inner layer and the mouth and neck of the inner layer body is provided with a protrusion or groove facing the other, and air from the ventilation path is used as an outside air introduction path with a gap or groove formed around the protrusion as an outer layer. To flow between the body and the inner layer It can be.

  According to the present invention, since the pulsation of the content liquid poured out as the container body is tilted can be suppressed even in a small-diameter dispensing cylinder, a convenient dispensing container in which the content liquid is not scattered around is provided. Can be provided.
