  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In addition, in each figure, the same members or parts are denoted by the same numerals and symbols in the tens place in the reference numerals, and duplicate descriptions are omitted.

  The dispensing container 100 of the embodiment shown in FIG. 1 is preferably used as a container for storing a relatively high content liquid (for example, a content liquid having a viscosity of about 5000 to 30000 mPa · s) such as an emulsion or a hand cream. In addition, the liquid content can be poured out without squeezing the side surface (body portion) of the container, and the container main body 102, the pouring cap 104, and the outer shell body 106 are mainly used. And a bottom pushing member 108 and an overcap 110.

  The container main body 102 has a mouth tube portion 102a, a shoulder portion 102b, a cylindrical body portion 102c, and a bottom portion 102d in order from the top. The container body 102 includes an outer layer body 112 and an inner layer body 114 that is thinner than the outer layer body 112 and is releasably adhered to the inner surface of the outer layer body 112. The storage space S1. The inner layer body 114 can be deformed and deformed inside the outer layer body 112 as the content liquid stored in the storage space S1 is poured out by a method described later and the content liquid decreases.

  Such a container body 102 is formed by, for example, blow molding a laminated parison formed by co-extrusion of a synthetic resin material for the outer layer body 112 and a synthetic resin material for the inner layer body 114 having low compatibility with a mold. Can be formed.

  The outer layer body 112 holds the outer shape of the container main body 102, and corresponds to each part of the container main body 102 in order from the top, the mouth tube portion 112a, the shoulder portion 112b, the cylindrical trunk portion 112c, and the bottom portion 112d. have.

  The bottom portion 112d of the outer layer body 112 is formed to have a smaller diameter than the body portion 112c, and a slit-like outside air introduction opening 118 for introducing outside air between the outer layer body 112 and the inner layer body 114 is formed on the bottom surface 116 thereof. Has been. Therefore, when the bottom pressing member 108 is pressed by a method described later, the air between the outer layer body 112 and the bottom pressing member 108 is introduced through the outside air introduction opening 118, thereby pressurizing the inner layer body 114.

  In this embodiment, the outside air introduction opening 118 opens a cut-off portion (pinch offline) formed on the bottom surface 116 of the outer layer body 112 by the joint of the mold when the container body 102 is formed by blow-molding the laminated parison. It is configured as an open bottom structure. Note that the outside air introduction opening 118 is not limited to the above structure, and may be any other type such as a through-hole formed by a punch or the like as long as it can introduce outside air between the outer layer body 112 and the inner layer body 114. It can also be configured.

  As shown in FIGS. 1 and 2, a bottom pushing member 108 is attached to the bottom 112 d of the outer layer body 112. In this embodiment, the bottom pressing member 108 includes a pressed portion 120 made of a synthetic resin or an elastomer that can be elastically deformed by a user's pressing operation, and a mounting portion 122 that fixes the pressed portion 120 to the bottom 112 d of the outer layer body 112. And have. The pressed portion 120 has a flange 124 sandwiched between the bottom surface 116 of the outer layer body 112 and the mounting portion 122 on the outer peripheral edge thereof, and is formed in a dome shape extending downwardly toward the container axis O therefrom. A space S <b> 2 is defined between the pressed part 120 and the bottom surface 116 of the outer layer body 112. In the center of the pressed portion 120, an outside air intake hole 126 for taking in outside air is provided between the bottom surface 116 of the outer layer body 112. Accordingly, the space S2 communicates between the outer layer body 112 and the inner layer body 114 through the outside air introduction opening 118 and also communicates with the outside of the container through the outside air intake hole 126.

  The mounting portion 122 includes a cylindrical mounting wall 132 formed on the inner peripheral surface of a female screw 130 that is screwed to a male screw 128 formed on the outer peripheral surface of the bottom portion 112 d of the outer layer body 112, and an outer peripheral surface of the mounting wall 132. A cylindrical grounding wall 134 extending downward from at least one of the grounding wall 134 in order to avoid interference with the user's finger during the pressing operation of the pressed portion 120 by the user. In the illustrated example, two notches 135 are formed at opposite locations. The outer peripheral surface of the ground wall 134 is preferably flush with the outer peripheral surface of the outer shell 106. In addition, in the example of illustration, although the to-be-pressed part 120 and the mounting part 122 are formed as a different body, you may form as an integral member.

  The outer shell body 106 has a cylindrical body portion 106c that covers the body portion 112c of the outer layer body 112 and a shoulder portion 106b that covers the shoulder portion 112b of the outer layer body 112, and a pouring cap is provided at the upper end of the shoulder portion 106b. 104 is integrally provided and held by the outer layer body 112 via the pouring cap 104. The outer shell body 106 is opened at the lower end, and can be attached to the container body 102 so as to be covered from above, and can be detachably fixed to the container body 102 via the pouring cap 104. The outer shell body 106 is formed with higher rigidity than the outer layer body 112 so as to restrict squeeze deformation of the body portion 112 c of the outer layer body 112. For this purpose, for example, a material having a higher tensile elastic modulus than the resin material of the outer layer body 112 is used as the material of the outer shell body 106, or the outer shell body 106 is formed thicker than the outer layer body 112. The outer shell 106 can be made of glass or metal. Further, when the outer shell body 106 is mounted by screwing the pouring cap 104 onto the inner surface of the shoulder section 106b of the outer shell body 106, rib-shaped protrusions formed on the outer peripheral surface of the shoulder section 112b of the outer layer body 112. A rib-like convex portion 137 is formed which overcomes 136 and provides a click feeling and prevents the pouring cap 104 and the outer shell body 106 from easily loosening.

  The dispensing cap 104 is attached to the mouth tube portion 102a of the container main body 102 (the mouth tube portion 112a of the outer layer body 112). In this embodiment, the dispensing cap 104 is an integral member with the outer shell body 106 and is therefore formed of the same material as the outer shell body 106. The pouring cap 104 has a top wall 140 that erects a cylindrical pouring outlet 138 in the center, and a cylindrical wall 142 that is suspended from the outer peripheral edge of the top wall 140, and has an internal thread formed on the cylindrical wall 142. 144 is configured to be screwed into a male screw 146 formed in the mouth tube portion 112a of the outer layer body 112. However, the present invention is not limited to this, and the pouring cap 104 is formed in the mouth tube portion of the outer layer body 112 as in an embodiment described later. It may be fixed to 112a through an undercut or the like.

  The overcap 110 covers the mouth tube portion 102 a of the container body 102 and seals the tip of the spout 138 of the spout cap 104. The overcap 110 hangs on the disk-shaped upper wall 148 and the outer peripheral edge of the upper wall 148. An annular seal protrusion 152 is formed at the center of the lower surface of the upper wall 148 and is fitted to the tip of the spout 138 of the spout cap 104. A threaded portion 156 that engages with a threaded portion 154 formed on the outer peripheral surface of the cylindrical wall 142 of the dispensing cap 104 is formed on the inner peripheral surface of the side wall 150. Instead of the overcap 110, the spout 138 may be hermetically sealed with a lid provided integrally and freely openable / closable on the spout cap 104 via a hinge.

  Further, in the dispensing container 100 of this embodiment, an annular concave rib 158 serving as a concave portion is provided over the entire circumference of the container body 102 at a substantially central position in the height direction. The concave rib 158 is formed by bending the container main body 102, that is, the outer layer body 112 and the inner layer body 114, inwardly over the entire circumference. The concave rib 158 has an annular recess on the outer peripheral surface side of the container body 102 and a rib-like shape on the inner peripheral surface side. Such a concave rib 158 can be formed, for example, by providing a molding rib in an annular shape at a corresponding position on the inner surface of the mold when blow molding a laminated parison using a mold.

  The position where the concave rib 158 is provided is, for example, when the portion of the inner layer body 114 below the concave rib 158 is inverted upward (from the mouth tube portion 102a side) with the concave rib 158 as a starting point. It is preferable that the tip of the inverted portion of the body 114 reaches the mouth tube portion 102 a but does not reach the top wall 140 of the pouring cap 104. The concave rib 158 may be formed intermittently along the circumferential direction.

  To dispense the content liquid using the thus constructed dispensing container 100, first, the overcap 110 is removed, and the dispensing container 100 is tilted obliquely downward as shown in FIG. In this state, as shown in FIG. 3 (b), the pressed portion 120 is opened while the outside air intake hole 126 of the pressed portion 120 of the bottom pressing member 108 is closed with a finger. When a pressing operation is performed toward the cylindrical portion 102 a, the air in the space S <b> 2 between the pressed portion 120 and the bottom surface 116 of the outer layer body 112 is pressurized, and the pressurized air passes through the outside air introduction opening 118 and the outer layer body 112 and the inner layer body 114. The inner layer body 114 is pressurized by the pressurized air, and the content liquid is pushed out through the spout 138 of the spout cap 104. When the content liquid is poured out, the inner layer body 114 is deformed and deformed by the volume of the poured out content liquid. At this time, since the outside air introduction opening 118 is disposed on the bottom surface 116 of the outer layer body 112, when the content liquid is poured out, the inner layer body 114 starts to peel from the bottom side portion. Subsequently, when the outside air intake hole 126 is opened and the pressed portion 120 is released, the inside of the space S2 becomes negative pressure due to the shape restoration based on the elastic characteristics of the pressed portion 120, and the outside air flows into the space S2. And the to-be-pressed part 120 returns to the original dome shape.

  In this way, when the pressed portion 120 is repeatedly pressed and released, and the content liquid is poured out from the inner layer body 114, the inner layer body 114 gradually moves from the bottom side toward the mouth tube portion 102a. Volume reduction deformation occurs while peeling from the outer layer body 112. However, when the peeling of the inner layer body 114 reaches the concave rib 158, as shown in FIG. 3 (c), the force to peel the inner layer body 114 is weakened by the lower slope 158a in the concave rib 158, Further peeling is prevented, and the inner layer body 114 is inverted and deformed from the concave rib 158 toward the mouth tube portion 102a, whereby the content liquid can be collected in the direction of the spout 138.

  Further, by reversing and deforming the inner layer body 114, it is possible to prevent the content liquid flow path toward the spout 138 from being blocked, and the tip of the inverted portion of the inner layer body 114 reaches the mouth tube portion 102a. When it reaches, the content liquid in the inner layer body 114 is pushed out from the spout 138 by this tip, so that the content liquid can be smoothly poured out even when the remaining amount of the content liquid decreases. .

  As described above, according to the dispensing container 100, even if the content liquid is poured out, it is possible to prevent the inflow of outside air from the spout 138 into the inner layer body 114. Therefore, the contents contained in the inner layer body 114 Deterioration due to contact of liquid with air can be suppressed. If the content liquid has a high viscosity, the content liquid stays in the region from the mouth tube portion 102a to the spout 138, so that the same function as the check valve is exhibited by the content liquid staying in the portion, Intrusion of outside air through the spout 138 can be prevented without providing a check valve.

  Further, in the dispensing container 100, the bottom pressing member 108 is provided on the bottom 112d of the outer layer body 112, and the inner layer body 114 is pressed using the bottom pressing member 108 to discharge the content liquid. The degree of freedom of design of the outer shell body 106 to be put on the body 112 can be increased, the appearance of the outer shell body 106 can be superior to that of a conventional squeeze-type dispensing container, and a high-class feeling can be given. Is possible. Further, by making the outer shell body 106 detachable, it is possible to replace the outer shell body 106. For example, when the content liquid in the container body 102 becomes empty, the outer shell body 106 is removed and a new one is removed. It can be reused by being mounted on a new container body 102.

  With reference to FIG. 4, the modification of the extraction container 100 shown in FIG. 1 is demonstrated. The pouring container 200 according to this modification is formed by separating the pouring cap 204 from the outer shell body 206.

  Specifically, the outer shell body 206 includes a cylindrical body portion 206c that covers the body portion 212c of the outer layer body 212 and a tapered tubular shoulder portion 206b that covers the shoulder portion 212b of the outer layer body 212. A fitting claw 260 that fits with the outer surface of the shoulder of the outer layer body 212 is provided on the inner surface of 206b. Further, the cylindrical wall 242 of the pouring cap 204 is formed shorter than that of the embodiment shown in FIG. 1 and is held by undercut fitting on the outer surface of the mouth tube portion 202a of the container body 202.

  In the pouring container 200, the screw portion 255 that engages with the screw portion 256 of the overcap 210 is provided not on the cylindrical wall 242 of the pouring cap 204 but on the outer peripheral surface of the mouth tube portion 212 a of the outer layer body 212. ing.

  With reference to FIG. 5, a dispensing container 300 of another embodiment according to the present invention will be described. In the dispensing container 300 of this embodiment, the outer layer body 312 is formed so as to be expandable and contractable in the outer shell body 306 along the height direction (the container axis O direction), and the outer layer body 312 is formed by pressing the bottom pressing member 308. The inner layer body 314 is pressurized by being reduced in the height direction, and the content liquid is poured out.

  Specifically, the concave portion formed at a substantially central position in the height direction of the container body 302 is formed as a mountain fold bent portion 358 that is bent and formed in a bellows shape over the entire circumference.

  As shown in FIGS. 5 and 6, the bottom pressing member 308 includes a disk-shaped pressed portion 320 having a push button 320 a protruding at the center, and a mounting portion 322 erected on the outer periphery of the pressed portion 320. The mounting portion 322 is screwed to the bottom 312d of the outer layer body 312. In this embodiment, since the pressing force of the pressed portion 320 is efficiently transmitted to the body portion 312c of the outer layer body 312 and the mountain fold bent portion 358 is contracted, the pressed portion 320 is increased in rigidity so as not to be deformed by the pressing operation. And is reinforced by reinforcing ribs 362. Further, in order to guide the movement of the bottom pushing member 308 by the outer shell body 306, the outer shell body 306 extends downward beyond the bottom pushing member 308, and a lower end portion thereof is a grounding portion 334. In addition, although the to-be-pressed part 320 and the mounting part 322 are formed as an integral member, these may be formed separately.

  In order to dispense the content liquid using the thus constructed dispensing container 300, first, the overcap 310 is removed, and the dispensing container 300 is tilted obliquely downward as shown in FIG. In this state, as shown in FIG. 7B, the pressed portion 320 is opened while the outside air intake hole 326 of the pressed portion 320 of the bottom pressing member 308 is closed with a finger. When a pressing operation is performed toward the cylindrical portion 302 a, the pressing force is transmitted to the body portion 312 c of the outer layer body 312 via the mounting portion 322, and the mountain folding portion 358 is contracted and deformed, and the mountain portion 312 c of the outer layer body 312 is The lower portion of the bent portion 358 moves toward the mouth tube portion 302a while being guided by the outer shell body 306. Thereby, the content liquid in the inner layer body 314 is pressurized, and the content liquid is pushed out through the spout 338 of the spout cap 304. Subsequently, when the outside air intake hole 326 is opened and the pressure to the pressed portion 320 is released, the body portion 312c of the outer layer body 312 is originally positioned by the shape restoration (extension) based on the elastic characteristics of the mountain fold bent portion 358. In this case, the negative pressure is generated between the outer layer body 312 and the inner layer body 314, and the air in the space S2 flows through the outside air introduction opening 318, and the inner layer body 314 is separated from the bottom side portion. In the pressing operation of the bottom pushing member 308 after the second time, air exists between the outer layer body 312 and the inner layer body 314. Therefore, when the outside air intake hole 326 is closed with a finger and the pressed portion 320 is pressed, The air between the inner layer bodies 314 is pressurized, the inner layer body 314 is pressurized by the pressurized air, and the content liquid is pushed out through the spout 338 of the spout cap 304.

  Thus, when the pressed portion 320 is repeatedly pressed and released, and the content liquid is poured out from the inner layer body 314, the inner layer body 314 gradually moves from the bottom side toward the mouth tube portion 302a. Volume reduction deformation occurs while peeling from the outer layer body 312. However, when the peeling of the inner layer body 314 reaches the mountain fold bent portion 358, as shown in FIG. 7C, the force for peeling the inner layer body 314 is caused by the lower slope 358a in the mountain folded bent portion 358. As a result of the weakening, further peeling is prevented, and the inner layer body 314 is inverted and deformed toward the mouth tube 302a starting from the mountain fold bent portion 358, thereby collecting the content liquid in the direction of the spout 338. Can do.

  Further, by reversing and deforming the inner layer body 314, it is possible to prevent the content liquid flow path toward the spout 338 from being blocked, and the tip of the inverted portion of the inner layer body 314 reaches the mouth tube portion 302a. When it reaches, the content liquid in the inner layer body 314 is pushed out from the spout 338 by the tip, so that the content liquid can be smoothly poured out even when the remaining amount of the content liquid decreases. .

  As described above, according to the dispensing container 300, even if the content liquid is poured out, it is possible to prevent the outside air from flowing into the inner layer body 314 from the spout 338, so that the contents contained in the inner layer body 314 are stored. Deterioration due to contact of liquid with air can be suppressed. In addition, when the viscosity of the content liquid is high, the content liquid stays in a region from the mouth tube portion 302a to the spout 338, so that the same function as the check valve is exhibited by the content liquid staying in the portion, Intrusion of outside air through the spout 338 can be prevented without providing a check valve.

  Further, in the dispensing container 300, the bottom pressing member 308 is provided on the bottom 312d of the outer layer body 312 and the inner layer body 314 is pressed using the bottom pressing member 308 to discharge the content liquid. The degree of freedom of design of the outer shell body 306 to be put on the body 312 can be increased, the appearance of the outer shell body 306 can be superior to that of a conventional squeeze-type pouring container, and a high-class feeling can be given. Is possible. Further, by making the outer shell body 306 detachable, the outer shell body 306 can be replaced. For example, when the content liquid in the container body 302 becomes empty, the outer shell body 306 is removed and a new one is removed. It can be reused by being mounted on a new container body 302.

  With reference to FIG. 8, the modification of the extraction container 300 shown in FIG. 5 is demonstrated. The pouring container 400 according to this modification is formed by separating the pouring cap 404 from the outer shell body 406.

  Specifically, the outer shell 406 has a cylindrical body 406c that covers the body 412c of the outer layer body 412, and a tapered cylindrical shoulder 406b that covers the shoulder 412b of the outer layer 412. A fitting claw 460 that fits with the outer surface of the shoulder 412b of the outer layer body 412 is provided on the inner surface of 406b. Further, the cylindrical wall 442 of the dispensing cap 404 is formed shorter than that of the embodiment shown in FIG. 5 and is held by undercut fitting on the outer surface of the mouth tube portion 402a of the container body 402.

  Further, in the pouring container 400, the screw portion 455 that engages with the screw portion 456 of the overcap 410 is provided not on the cylindrical wall 442 of the pouring cap 404 but on the outer peripheral surface of the mouth tube portion 412 a of the outer layer body 412. ing.

  As mentioned above, although demonstrated based on the example of illustration, this invention is not limited to the above-mentioned embodiment, A various change and addition are possible. For example, in the above-described embodiment, the container main bodies 102, 202, 302, and 402 are laminated by forming the outer layer bodies 112, 212, 312, and 412 and the inner layer bodies 114, 214, 314, and 414 by the blow molding of the laminated parison.
