その一つの形態として、積層ボトルの軸線方向に沿って
一直線に接合部を設けたものがある。In this laminated bottle, the inner layer is removably laminated inside the outer layer, and the outer layer and a part of the inner layer are joined together. There are various thoughts about the installation position of the joint portion that joins the outer layer and the inner layer,
As one form thereof, there is one in which a joint portion is provided in a straight line along the axial direction of the laminated bottle.

の密着部分の両側に密閉空間３４，３５を形成する。FIG. 6 is a cross-sectional view of a laminated bottle 30 having only one joint 33 extending linearly along the axial direction. In this case, when the inner layer 32 peels from the outer layer 31 as the content decreases, the peeling starts from a portion away from the joint portion 33. Then, as the shrinkage of the inner layer 32 progresses, the peeled inner layer 32 adheres to the inner layer 32 in the vicinity of the joint portion 33 as shown in FIG.
【０００５】このように密閉空間３４，３５が生じる

虞があり、不経済であった。When the sealed spaces 34 and 35 are generated in this manner, the contents in the sealed spaces 34 and 35 may remain unpoured, which is uneconomical.

場合があった。Further, in many cases, a laminated bottle of this type is
A pour pump (not shown) is attached to the mouth cylinder of the laminated bottle, and the suction pipe of the pour pump is inserted into the inner layer from the mouth cylinder, but the peeled inner layer contracts as described above. Then, the inner layer pushes and bends the suction tube, which may interfere with the normal operation of the dispensing pump and adversely affect the dispensing of the contents.

らである。This problem similarly occurs when two joint portions extending linearly along the axial direction are provided facing each other in the circumferential direction. When two joining portions are provided in this way, the inner layer is divided into two, but the peeling of the inner layer starts from one side and progresses, and both sides simultaneously peel,
Because it does not contract. The reason why the peeling starts from only one side in this way is that the inner layer is generally uneven in thickness in the circumferential direction, and the thin side is easier to peel from the outer layer than the thick side. When two joints are provided in the circumferential direction, it is difficult to arrange the joints at equal intervals, and a slight dimensional error occurs in the circumferential direction. At that time, the longer circumferential length is outside the shorter one. This is because it is easy to peel from the layer.

Another object of the present invention is to obtain a laminated bottle that does not interfere with the normal operation of the pouring pump.

項１に対応）。The present invention adopts the following means in order to solve the above problems. The present invention provides a laminated bottle comprising at least two layers of an inner layer and an outer layer that are releasably laminated to each other, wherein a part of the inner layer and the outer layer are joined at a joint portion extending along the axial direction, The three or more joints are provided in the circumferential direction so as to be spaced apart from each other, and the distance between the two joints adjacent to each other is measured along the circumferential direction, and the distance between the two joints is the axial center of the laminated bottle. The dimension measured in a straight line via the is set to substantially the same dimension (corresponding to claim 1).

分の剥離が始まり、順次に剥離、収縮が行われる。In the laminated bottle of the present invention, when the inner layer peels from the outer layer and shrinks as the content decreases, the inner layer is divided into the same number as the number of joints and peels and shrinks. Which section of the inner layer starts peeling depends on the thickness distribution of the inner layer and the difference in the circumferential length between the joints, and when shrinkage of the inner layer of the first peeled section is completed, another section is separated. Peeling starts, and peeling and shrinking are sequentially performed.

いるので、接合部で分割された内側層の各区分は、各区
分の途中部が積層ボトルのほぼ軸中心に到達した時に収
縮を終了し、これ以上の収縮は寸法上、不可能となる。Since the dimension between the joints is set as described above, each section of the inner layer divided at the joints contracts when the middle part of each section reaches approximately the axial center of the laminated bottle. When it is finished, no further shrinkage is possible due to its dimensions.

位置であっても構わない。At least one air hole is preferably provided between the joints of the outer layers (corresponding to claim 2). With this configuration, air can be surely allowed to flow from the air holes between the outer layer and the inner layer, and the inner layer can be reliably and smoothly contracted. The installation position of the air hole may be any position such as the mouth cylinder part, body part, and bottom part of the laminated bottle.

している。The laminated bottle 1 is provided with a cylindrical body portion 2 and a cylindrical mouth tube portion 3 connected to the upper portion of the body portion 2. The laminated bottle 1 is entirely formed by laminating an outer layer 11 and an inner layer 12 from the mouth tube portion 3 to the bottom portion 4 of the body portion 2. The outer layer 11 and the inner layer 12 have three joints 1
3A, 13B, and 13C are joined to each other, but at portions other than these joined portions 13, the outer layer 11 and the inner layer 12 are in contact with each other and can be separated. FIG. 2 shows a state before the inner layer 12 is separated from the outer layer 11.

３Ａ間についても同様である。By the way, when the outer diameter of the inner layer 12 is D, the separation dimension L 1 measured along the circumferential direction of two adjacent joints (for example, 13A and 13B) is L 1 = πD / 3 = 1 .05D, which is approximately the same as the dimension L 2 = D measured linearly between the two joints (13A, 13B) via the axial center P of the laminated bottle 1. This dimensional relationship is between the joints 13B and 13C, or the joints 13C and 1C.
The same applies between 3A.

配するのが一般的である。In this laminated bottle 1, a spout pump (not shown) is attached to the mouth cylinder part 3, and a suction pipe of the spout pump is inserted from the mouth cylinder part 3 into the inner layer 12 so that the inside of the inner layer 12 is covered. Pump up the stored contents and pour out. This time,
Generally, the suction pipe of the pouring pump is arranged substantially at the axial center of the laminated bottle 1.

側層１１から剥離することはない。For example, in FIG. 2, the joints 13A, 13A
Assuming that the inner layer 12A located between B is first separated from the outer layer 11, the inner layer 12B located between the joints 13B and 13C is kept until the inner layer 12A finishes shrinking.
The inner layer 12C located between the joint portions 13C and 13A is not separated from the outer layer 11.

2A almost completes its contraction when its middle portion in the circumferential direction comes into contact with the suction pipe of the pump. And the inner layer 1
When the contraction of 2A is completed, the inner layer 12B or 12C
Either one of them peels off from the outer layer 11 and starts shrinking,
When the contraction of the inner layer is completed, the inner layer that remains last is separated from the outer layer 11 and starts contracting.

する。Since the inner layer 12 always contracts in such a form, almost all of the contents can be discharged by the discharge pump. In addition, when the inner layers 12A to 12C contract, air flows between the outer layer 11 and the inner layers 12A to 12C from the air holes 14 provided in the corresponding portions, and the inner layers 12A to 12C contract. Surely and smoothly.

出ポンプを正常に動作せしめることができる。Further, the inner layers 12A to 12C of the respective sections, due to their dimensions, only lightly contact the suction pipe of the pouring pump and cannot push and bend the suction pipe. Therefore, the contraction of the inner layer 12 does not adversely affect the operation of the pouring pump, and the pouring pump can be normally operated until the final contents are poured.

空気孔を設けなくても、内側層の収縮が可能である。When the bottom of the bottle is formed by pinch-off processing, the inner layers are completely joined together, but the outer layers are not joined together. Therefore, when a shock is applied by poking the bottom of the bottle with a rod or the like after molding, a slit is formed between the outer layer and the inner layer in the pinch-off portion, and air is formed between the outer layer and the inner layer from this slit. Inflow is possible. Therefore, in this way, it is possible to shrink the inner layer without providing air holes in the outer layer.
