However, in the above-described conventional bottles, the diameter of the mouth portion, which is a connecting portion between the bottles stacked up and down, is small, and these bottles cannot be stacked stably.
On the other hand, it is conceivable to place the bottom of another bottle on the shoulder using a shoulder having a diameter larger than the mouth, but generally the shoulder is directed radially inwardly perpendicular to the bottle axis. Accordingly, when the bottle bottom is placed on this inclined portion, the stacked state becomes unstable.

  The present invention has been made in view of such circumstances, and it is possible to stably stack a plurality of bottles in the bottle axial direction while including a shoulder portion that is shaped to easily pour the contents. The purpose is to provide bottles.

In order to solve the above problems, the present invention proposes the following means.
The present invention is a bottle in which a mouth portion, a shoulder portion, a body portion, and a bottom portion are continuously provided in this order along the bottle axial direction, and the shoulder portion is deformed so as to be rotatable around an outer peripheral edge portion thereof. In the pouring posture that gradually inclines toward the upper side of the mouth side along the bottle axis direction as it goes inward in the radial direction perpendicular to the bottle axis, and gradually in the bottle axis direction as it goes inward of the radial direction Any of the stacking postures inclined downward toward the bottom side along the bottom can be selected, and the bottom portion is a grounding portion located on the outer peripheral edge portion and a depression recessed on the bottle shaft. The other bottles on the outer peripheral edge portion of the shoulder portion in the stacked posture in a state where the mouth portion is housed in the depressed portion of another bottle different from the bottle. is configured to the grounding portion of is placed, the said opening Between the parts, they provided the neck portion connecting the connecting portion between the shoulder portion of the neck, characterized in that it is inclined gradually toward the outside in the radial direction toward the upper side.

  According to the bottle of the present invention, since either the pouring posture or the stacking posture can be selected by deforming the shoulder portion, the shoulder portion is poured when pouring the contents contained in the bottle. It is easy to pour out the contents by adopting the exit posture. Also, when stacking multiple bottles in the bottle axial direction for storage (stacking), the shoulder is in a stacking posture, and the grounding part at the bottom of the other bottle is placed on the outer peripheral edge of the shoulder By doing so, these bottles can be stacked stably.

Specifically, conventionally, when stacking a plurality of bottles in the bottle axial direction, for example, the mouth portion of one bottle located below is fitted to the bottom of another bottle located above, The bottom of the other bottle was placed on the inclined part of the shoulder, but the other bottle arranged on the one bottle becomes an unstable posture, and these bottles can be stacked stably. could not.
On the other hand, according to the present invention, the mouth portion of the one bottle located below is housed in the recessed portion of the other bottle located above, and the other bottle at the outer peripheral edge portion of the shoulder portion of the one bottle. Since the outer peripheral edge portion (grounding portion) of the bottom portion of the bottle can be supported, the stacking posture of these bottles is stabilized.

  As described above, according to the present invention, it is possible to stably stack a plurality of bottles in the bottle axial direction while providing a shoulder portion that is easy to pour the contents.

Further, between the front Symbol mouth the shoulder, neck portion is provided for connecting the connection portion between the shoulder portion of the neck, gradually inclined toward the outer side in the radial direction toward the upper you are.

Lower the connection portion of the neck portion, from being formed along the shape of the shoulder portion which is a stacked position, when the stack posture shoulders from dispensing position, the shoulder portion by the connecting portion And can be easily deformed into a stack posture. Further, when the shoulder portion is pushed down, the neck portion and the mouth portion above the neck portion are not easily tilted with respect to the bottle shaft, and the stacking posture of the plurality of bottles is further stabilized.

  In the bottle of the present invention, the bottom of the other bottle may be placed on the neck while the shoulder is in the stacking posture.

  In this case, as described above, the grounding portion at the bottom of the other bottle is placed on the outer peripheral edge of the shoulder of the bottle, and the other bottle is also placed on the neck located on the radially inner side of the outer peripheral edge. Since the bottom portion of the bottle is placed, the stacking posture of the plurality of bottles becomes more stable.

  Further, in the bottle of the present invention, a cap that detachably covers the mouth portion is provided, and the cap and the mouth portion are in the recessed portion of the other bottle in a state where the cap is attached to the mouth portion. It is good also as being able to be stored.

  In this case, a plurality of bottles can be stably stacked regardless of before and after filling the contents in the bottle, and it is possible to deal with various stacking modes, which is convenient.

  According to the bottle according to the present invention, it is possible to stably stack a plurality of bottles in the bottle axial direction while having a shoulder portion that is easy to pour the contents.

It is a front view which shows the bottle which concerns on one Embodiment of this invention. It is a figure explaining the state accumulated using the bottle of FIG. 1 in the bottle axial direction.

Hereinafter, bottle 1 concerning one embodiment of the present invention is explained with reference to drawings.

  According to the bottle 1 of the present embodiment described above, since either the pouring posture or the stacking posture can be selected by deforming the shoulder portion 3, the contents accommodated in the bottle 1 are poured out. In some cases, the contents can be easily poured out by setting the shoulder 3 to the pouring posture. Further, when stacking and storing (stacking) a plurality of bottles 1A, 1B in the direction of the bottle axis O, the shoulder 3 of the lower bottle 1A is set in a stacking posture and placed on the outer peripheral edge 3a of the shoulder 3 By placing the grounding portion 5a of the bottom 5 of the upper bottle 1B, these bottles 1A and 1B can be stably stacked.

Specifically, conventionally, when stacking a plurality of bottles in the bottle axial direction, for example, the mouth portion of one bottle located below is fitted to the bottom of another bottle located above, The bottom of the other bottle was placed on the inclined part of the shoulder, but the other bottle arranged on the one bottle becomes an unstable posture, and these bottles can be stacked stably. could not.
On the other hand, according to the present embodiment, the mouth portion 2 of one bottle 1A located below is housed in the depressed portion 5b of the other bottle 1B located above and outside the shoulder portion 3 of one bottle 1A. Since the outer peripheral edge part (grounding part 5a) of the bottom part 5 of the other bottle 1B can be supported by the peripheral edge part 3a, the stacked posture of these bottles 1A and 1B is stabilized.

  As described above, according to the present embodiment, the plurality of bottles 1 can be stably stacked in the direction of the bottle axis O while the shoulder portion 3 having a shape in which the contents are easily poured out is provided.

Moreover, the neck part 6 which connects these is provided between the opening | mouth part 2 and the shoulder part 3, and the connection part (lower part 6b) with the shoulder part 3 in the neck part 6 is gradually diameter as it goes upwards. Since it is inclined toward the outside of the direction, the following effects are produced.
That is, the connecting portion (the lower portion 6b) of the neck portion 6 is formed so as to follow the shape of the shoulder portion 3 in the stacking posture shown in FIG. When the stack posture of FIG. 2 is changed from the posture, the shoulder portion 3 can be easily pushed downward by the connecting portion and can be easily deformed to the stack posture. Further, when the shoulder portion 3 is pushed down, the neck portion 6 and the mouth portion 2 above the neck portion 6 are not easily tilted with respect to the bottle axis O, and the stacked posture of the plurality of bottles 1 is further stabilized.

Further, when the bottom portion 5 of the other bottle 1B can be placed on the neck portion 6 in a state where the shoulder portion 3 of one bottle 1A is in the stacking posture, the following effects can be obtained.
That is, as described above, the grounding portion 5a of the bottom portion 5 of the other bottle 1B is placed on the outer peripheral edge portion 3a of the shoulder portion 3 of the bottle 1A, and is positioned on the radially inner side of the outer peripheral edge portion 3a of the bottle 1A. Since the bottom portion 5 of the other bottle 1B is also placed on the neck portion 6 to be stacked, the stacking posture of the plurality of bottles 1A and 1B becomes more stable.

  Moreover, in this embodiment, the cap 7 which covers the mouth part 2 so that attachment or detachment is possible is provided in the bottle 1 to be stacked, and when the cap 7 is attached to the mouth part 2, the cap 7 and the mouth part 2 are Since it can be stored in the recessed portion 5b of another bottle 1B, a plurality of bottles 1 can be stably stacked regardless of before and after the bottle 1 is filled with the contents, corresponding to various stacking modes. It is easy to use.

  Further, since the panel surface 3b of the shoulder portion 3 is flat, it is easy to allow the deformation of the shoulder portion 3 described above, and the ridge line portion 3c located between the adjacent panel surfaces 3b. This prevents the rigidity of the shoulder 3 from being reduced to a predetermined value or less. The flat panel surface 3b can be easily bulged and deformed according to fluctuations in the internal pressure of the bottle 1.
