  However, the conventional bottles are difficult to separate when the stacked bottles are in close contact with each other.

  This invention is made | formed in view of the situation mentioned above, Comprising: It aims at making it easy to isolate | separate the accumulated bottles.

In order to solve the above problems, the present invention proposes the following means.
The bottle according to the present invention is a bottle in which a mouth portion, a main body portion, and a bottom wall portion are continuously provided in this order in the bottle axial direction, and the main body portion is formed with a bent portion so as to be bent and deformable. Is formed over the entire circumference, and of the main body portion, one side portion located on one side in the bottle axial direction with respect to the bent portion is directed toward the other side in the bottle axial direction with the bent portion as a center. The one side portion can be reversely deformed, and the one side portion is reversely deformed to enter the other side portion located on the other side in the bottle axial direction with respect to the bent portion, and in the one side portion that has been reversely deformed. Is provided with an accommodating portion for accommodating the other side portion of another bottle different from the bottle in a state in which the connecting portion connected to the bent portion is protruded in the other side portion, Has a protruding part that protrudes outward in the bottle radial direction. It is characterized in that is.

  According to this invention, in order to stack a plurality of bottles, when the other side portion of another bottle is accommodated in the accommodation portion of one bottle, the connection portion of the other bottle projects from the accommodation portion. Here, the connecting portion is provided with a protruding portion. Therefore, even if the stacked bottles are in close contact with each other, both bottles can be separated from each other in the bottle axial direction by easily applying an external force to the bottles from the protruding portions. Can be made easier.

  The protruding portion may be provided over the entire circumference.

  In this case, the protrusion is provided over the entire circumference. Therefore, for example, it is possible to easily apply an external force from the user to the protruding portion regardless of the direction of the stacked bottles with respect to the user. Thereby, the stacked bottles can be more easily separated.

  The one side portion and the other side portion may be provided with a restricting portion that locks each other when the one side portion is inverted and deformed and restricts the deformation of the one side portion.

  In this case, since the restricting portions are provided in the one side portion and the other side portion, it is possible to easily maintain the state where the one side portion is deformed in an inverted manner and enters the other side portion.

  When the accommodation part of the bottle accommodates the other side part of the other bottle, the bent part of the bottle and the connection part of the other bottle are locked, You may restrict | limit that the other side part approachs into the said accommodating part of the said bottle further.

  In this case, when the accommodation part of one bottle accommodates the other side part of the other bottle, the bent part of one bottle and the connection part of the other bottle are locked, and the other side part of the other bottle Restricts further entry into the container of one bottle. Therefore, it is possible to reliably project the connection portion of the other bottle from the storage portion of one bottle while suppressing the complexity of the bottle structure.

  The protrusion may be disposed at an end portion on the one side of the connection portion.

In this case, the protruding portion is disposed at one end of the connection portion. Therefore, the said edge part of a connection part can be reinforced with a protrusion part. Thereby, since one side part is reversed and deformed, when a force in the bottle axial direction is applied to the bottle, the force applied to the bottle by the end portion of the connecting portion can be effectively received. As a result, the bent portion can be smoothly bent and deformed, and the one side portion can be easily reversed and deformed.
In addition, when the protrusion part is provided over the perimeter, it becomes possible to heighten the reinforcement effect by a protrusion part, and can make it easier to reversely deform one side part.

  According to the present invention, it is possible to easily separate the stacked bottles.
