FIG. 8 is a diagram illustrating a state in which the bottle container 100 according to the embodiment is crushed, in which (a) illustrates the shape of the mouth-and-neck portion 10 when viewed in the axial center X direction of the mouth-and-neck portion 10, b) shows the cross-sectional shape of the shoulder portion 21 of the main body portion 20.

The bottle container 100 according to the present embodiment has a mouth / neck portion 10 and a main body portion 20 having a larger cross-sectional area than the mouth / neck portion 10 and accommodating contents. Here, the cross-sectional area of the mouth-and-neck part 10 means, for example, the cross-sectional area of the mouth-and-neck part 10 when cut along a plane orthogonal to the axis X of the mouth-and-neck part 10. In this case, the cross-sectional area of the main body portion 20 means the cross-sectional area of the main body portion 20 when cut along a plane orthogonal to the extension line of the axis X of the mouth-and-neck portion 10. Since the helical thread 15 and the thread groove 16 are formed on the outer peripheral surface of the mouth-and-neck portion 10, the mouth-and-neck portion 10 is formed in a male screw shape. On the outer peripheral surface of the mouth / neck portion 10, a screw dividing portion 31 formed by dividing the screw thread 15 is formed so as to extend in parallel with the axis X of the mouth / neck portion 10. A groove-like portion 40 is formed on the outer surface of the main body 20 so as to extend in the extending direction of the screw dividing portion 31 when the screw dividing portion 31 is viewed from the front. When the bottle container 100 is crushed on the end of the main body 20 opposite to the thread dividing portion 31 side of the groove 40, the middle of the groove 40, or the extension of the groove 40. A pressing portion 50 indicating the pressing position is formed.
Here, in this specification, “looking straight” means viewing the target portion in a state of facing the target portion. For example, looking straight at the screw dividing portion 31 means viewing the screw dividing portion 31 while facing the screw dividing portion 31.

  Moreover, the bottle container stuffed product 200 according to the present embodiment includes a bottle container 100 according to the present embodiment, a content 160 accommodated in the bottle container 100, and a lid attached to the mouth and neck portion 10 of the bottle container 100. Part 153.

  In addition, in this specification, the upper and lower positional relationship of each component in the bottle container 100 and the bottle container stuffed product 200 will be described as the positional relationship when the bottle container 100 is placed upright on a horizontal surface. . However, this positional relationship does not necessarily match the positional relationship when the bottle container 100 and the bottle container stuffed product 200 are used, stored, transported, manufactured, or the like.

  First, the structure of the bottle container 100 will be described with reference to FIGS.

The bottle container 100 is thinly formed of a flexible material so that it can be easily crushed by hand. In the bottle container 100, the inner surface has a concave shape at a portion where the outer surface has a convex shape.
The bottle container 100 can be produced, for example, by blow molding using a resin material.
However, the material of the bottle container 100 is not limited to resin. The bottle container 100 may be formed to be thin using a metal material, for example.

  The bottle container 100 includes a mouth / neck portion 10 and a main body portion 20. The mouth-and-neck portion 10 is formed in a cylindrical hollow shape. The upper end of the mouth and neck 10 is an opening 10a. A main body 20 is connected to the lower end of the mouth / neck 10. The main body portion 20 is a hollow body having a bottom, and the contents can be accommodated therein. The internal space of the mouth / neck portion 10 and the internal space of the main body portion 20 communicate with each other.

  More specifically, the mouth-and-neck portion 10 is formed in, for example, a cylindrical large-diameter portion 11 and a cylindrical shape that is positioned above the large-diameter portion 11 and smaller in diameter than the large-diameter portion 11. And a tapered portion 12 which is located between the small diameter portion 13 and the large diameter portion 11 and which connects the small diameter portion 13 and the large diameter portion 11 to each other. The diameter of the lower end of the tapered portion 12 is the same as the diameter of the large diameter portion 11, and the diameter of the upper end of the tapered portion 12 is the same as the diameter of the small diameter portion 13. The tapered portion 12 is formed in a tapered shape that gradually decreases in diameter from the lower end toward the upper end. The small diameter part 13, the taper part 12, and the large diameter part 11 are arranged coaxially with each other.

On the outer peripheral surface of the mouth-and-neck portion 10, a spiral thread 15 centering on the axis X of the mouth-and-neck portion 10 is formed. As a result of the thread 15 being formed on the outer peripheral surface of the mouth-and-neck portion 10, the portion between the adjacent screw threads 15 on the outer peripheral surface of the mouth-and-neck portion 10 constitutes a thread groove 16. Specifically, for example, the screw thread 15 is formed on the outer peripheral surface of the large-diameter portion 11, and the screw groove 16 is configured by a part of the outer peripheral surface of the large-diameter portion 11.
By forming the screw thread 15 and the screw groove 16 in this way, the mouth-and-neck portion 10 has a male screw shape.

Further, a neck ring 17 is formed on a portion of the outer peripheral surface of the large-diameter portion 11 positioned below the portion where the screw thread 15 is formed. The neck ring 17 is an annular ridge, and is formed along a plane orthogonal to the axis X of the mouth-and-neck portion 10. For example, the protruding height from the outer peripheral surface of the large-diameter portion 11 is equal between the neck ring 17 and the screw thread 15.
The neck ring 17 is a guide for allowing the manufacturing apparatus (not shown) to stably hold the bottle container 100 when the bottle container 100 is molded and when the bottle container 100 is filled with contents. It functions as a part.

  Note that a so-called pedestal (see reference numeral 18 in FIG. 10) is not formed at the lower end position of the mouth / neck portion 10 (the boundary portion between the mouth / neck portion 10 and the main body portion 20). For this reason, the mouth-and-neck portion 10 can be easily crushed.

The main body 20 includes, for example, a shoulder 21 adjacent below the mouth and neck 10, a trunk 22 adjacent below the shoulder 21, and a bottom 23 adjacent below the trunk 22. And have.
The shoulder 21 has a cross-sectional area that is reduced upward (for example, gradually reduced).
The bottom 23 is reduced (for example, gradually reduced) in cross-sectional area downward.
The body portion 22 has a cylindrical shape with a substantially constant cross-sectional area from the upper end portion to the lower end portion.

Although the cross-sectional shape of the main-body part 20 may be circular, it is formed in the ellipse shape, for example. That is, the main body 20 has, for example, a flat shape having a first direction in which the thickness dimension of the outer shape is relatively small and a second direction in which the thickness dimension of the outer shape is relatively large. For this reason, the main body part 20 has a relatively wide front part 20a and a back part 20b, and a pair of relatively narrow side parts 20c, 20d.
In other words, the main body portion 20 has a flat shape in which a cross section perpendicular to the axis X of the mouth-and-neck portion 10 has a short axis and a long axis. In the shoulder portion 21, the short axis and the long axis are gradually shortened upward, and in the bottom portion 23, the short axis and the long axis are gradually shortened downward. In the body portion 22, the lengths of the short axis and the long axis can be made substantially constant. In the structure illustrated in FIG. 1 and the like, in the body portion 22, the length of the long axis is slightly longer toward the lower side, but gradually becomes longer, and has a highly stable shape.

  A first ridge line (ridge line) 81 extending along the circumferential direction of the main body portion 20 is formed at the boundary portion between the shoulder portion 21 and the body portion 22. More specifically, the first ridge line 81 is formed over the entire circumference in the circumferential direction of the main body 20, or is formed over the entire circumference in the circumferential direction of the main body 20. In addition, in an arbitrary cross section intersecting the first ridgeline 81 among the cross sections along the axial center of the mouth-and-neck part 10, the outline of the main body part 20 is bent at the boundary between the shoulder part 21 and the trunk part 22. (FIG. 3D).

  Similarly, a second ridge line 82 extending along the circumferential direction of the main body portion 20 is formed at the boundary portion between the body portion 22 and the bottom portion 23. More specifically, the second ridge line 82 is formed over the entire circumference in the circumferential direction of the main body 20, or is formed over the entire circumference in the circumferential direction of the main body 20. Of the cross-sections along the axis of the mouth-and-neck part 10, the external line of the main body part 20 is bent at the boundary between the body part 22 and the bottom part 23 in any cross-section that intersects with the second ridgeline 82. (FIG. 3 (d)).

The first ridge line 81 is formed in a wavy line shape, for example. For example, the first ridge line 81 swells most upward in the horizontal central portion of the front surface portion 20a and the back surface portion 20b, and swells downward most in the horizontal central portion of the side surface portion 20c and the side surface portion 20d.
Similarly, the second ridge line 82 is formed in, for example, a wavy line shape. For example, the second ridge line 82 is formed in a shape that is substantially vertically symmetric with respect to the first ridge line 81. That is, for example, the second ridge line 82 swells downward most in the horizontal central part of the front part 20a and the back part 20b, and swells upward most in the horizontal central part of the side part 20c and the side part 20d. Yes.

As described above, on the outer peripheral surface of the mouth-and-neck portion 10, the screw dividing portion 31 having a form that divides the screw thread 15 is formed. The screw dividing portion 31 extends in parallel to the axis X of the mouth / neck portion 10. More specifically, for example, the screw dividing portion 31 extends in parallel to the axis X. Therefore, the screw parting portion 31 extends linearly.
The screw parting portion 31 is formed, for example, at a portion that becomes the center of the mouth-and-neck portion 10 when the back surface portion 20b is viewed from the back (state of FIG. 1A). In addition, the screw thread 15 circulates the outer peripheral surface of the mouth-and-neck part 10 a plurality of times, and when the back surface part 20b is viewed from the back, the screw thread 15 is formed in a plurality of strips. The screw dividing portion 31 extends vertically so as to divide the plurality of threads 15.
When the bottle container 100 has the neck ring 17 as in the present embodiment, it is preferable that the thread dividing portion 31 also divides the neck ring 17.

  For example, the upper end position of the screw dividing portion 31 coincides with the upper end position of the tapered portion 12, and the lower end position of the screw dividing portion 31 coincides with the lower end position of the large diameter portion 11. In addition, as will be described later, the screw dividing portion 31 is connected to the groove-shaped portion 40, for example.

The thread dividing portion 31 is, for example, a second groove-shaped portion formed in a groove shape in which at least the end on the groove-shaped portion 40 side is recessed from the screw groove 16. More specifically, for example, the entire thread dividing portion 31 is a second groove-shaped portion. And the 2nd groove-shaped part and the groove-shaped part 40 are formed in the groove shape which continues mutually. That is, the second groove-shaped portion constitutes a part of the single groove, and the groove-shaped portion 40 constitutes the remaining portion of the single groove.
For example, the second groove-shaped portion is formed at the same depth as the outer peripheral surface of the small-diameter portion 13. That is, the distance from the axial center X of the mouth-and-neck portion 10 to the outer peripheral surface of the small-diameter portion 13 and the distance from the axial center X to the bottom of the second groove-shaped portion of the screw dividing portion 31 are equal to each other.

  The screw dividing portion 31 is formed, for example, in a trapezoidal cross-sectional shape (see FIG. 3A, FIG. 4A, FIG. 5A, etc.). Thereby, when discarding the bottle container 100, for example, in the mouth-and-neck portion 10, the mouth-and-neck portion 10 is crushed by crushing the mouth-and-neck portion 10 until the portions located on both sides of the screw dividing portion 31 come into contact with each other. It can be made sufficiently flat (see FIG. 8A). In addition, although the cross-sectional shape of the screw parting part 31 may be V-shaped or U-shaped, the mouth-and-neck part 10 can be crushed more flatly by using a trapezoidal shape.

  As described above, the groove-shaped portion 40 is formed on the outer surface of the main body portion 20. The groove-shaped portion 40 is a portion having a shape that is recessed from the portion around the groove-shaped portion 40 on the outer surface of the main body portion 20. The groove-like portion 40 extends in the extending direction of the screw dividing portion 31 when the screw dividing portion 31 is viewed from the front. More specifically, for example, when the screw dividing portion 31 is viewed from the front, the screw dividing portion 31 and the groove portion 40 are arranged so that the screw dividing portion 31 and the groove portion 40 exist on the same straight line. It is preferable. In other words, the groove-like portion 40 preferably extends along a plane including the axis X of the mouth-and-neck portion 10 and the screw dividing portion 31.

  For example, the groove-like portion 40 is formed in the main body portion 20 at least in a portion adjacent to the mouth-and-neck portion 10. That is, in the main body portion 20, at least a portion adjacent to the mouth / neck portion 10 is formed with a groove-like portion 40 extending in the extending direction of the screw dividing portion 31 when the screw dividing portion 31 is viewed from the front.

  For example, the screw dividing portion 31 and the groove-like portion 40 are connected to each other. That is, the screw parting portion 31 and the groove-like portion 40 are continuously formed with each other. More specifically, the screw parting portion 31 and the groove-like portion 40 are formed in a single continuous groove shape and do not have a step at the boundary between them. For example, the lower end of the groove-shaped portion 40 reaches the first ridgeline 81 or reaches a position near the first ridgeline 81.

Furthermore, a second screw dividing portion 32 formed by dividing the screw thread 15 is formed in the mouth and neck portion 10. The second screw dividing portion 32 has the same structure as the screw dividing portion 31. The second screw dividing portion 32 is formed to extend in parallel with the screw dividing portion 31. More specifically, for example, the second screw dividing portion 32 extends in parallel with the axis X of the mouth-and-neck portion 10. Therefore, the second screw dividing portion 32 extends linearly. The second screw dividing portion 32 is formed on the outer peripheral surface of the mouth and neck portion 10 at a location facing the screw dividing portion 31 with the axis X interposed therebetween.
When the bottle container 100 has the neck ring 17 as in the present embodiment, it is preferable that the second screw dividing portion 32 also divides the neck ring 17.

Further, the mouth-and-neck portion 10 is formed with a pair of low-step portions 33 formed by forming or dividing the screw thread 15 at a lower step than the surroundings. The low step portion 33 is formed on each of the outer peripheral surfaces of the mouth-and-neck portion 10 as the side surfaces when the portion where the screw dividing portion 31 is formed is the front surface.
When the bottle container 100 includes the neck ring 17 as in the present embodiment, it is preferable that the neck ring 17 is formed at a lower stage than the surroundings or is divided at the place where the low stage part 33 is formed.

In the case of the present embodiment, the low step portion 33 is, for example, a portion having a shape obtained by partially cutting and removing the screw thread 15 along a plane parallel to the axis X of the mouth-and-neck portion 10 (see FIG. 5 (a), (b) etc.).
By forming the low step portion 33 in this way, when the bottle container 100 is molded by blow molding or the like, it can be easily released from the molding die, and the thread 15 can be left as much as possible. Therefore, the mouth-and-neck portion 10 and the lid can be more reliably screwed together.
More specifically, the low step portion 33 is, for example, a portion having a shape obtained by partially cutting and removing the thread 15 and the neck ring 17 along a plane parallel to the axis X of the mouth-and-neck portion 10. It is.

  For example, the distance from the axis X of the mouth-and-neck portion 10 to the thread groove 16 and the distance from the axis X to the low step portion 33 are equal to each other. Specifically, for example, the distance from the center 33a of the low step portion 33 to the axis X in plan view and the distance from the screw groove 16 to the axis X are equal to each other, and the low step portion 33 has its center 33a. , The thread 15 and the neck ring 17 are divided. That is, on the outer peripheral surface of the mouth-and-neck portion 10, each of the portions that become the side surfaces when the portion where the screw dividing portion 31 is formed is a front surface. The center 33a) of the part 33 is formed, and the distance from the axis X of the mouth-and-neck part 10 to the screw groove 16 is equal to the distance from the axis X to the side screw part. A center 33 a of the low step portion 33 extends in parallel with the axis X.

Here, in the case of the present embodiment, in the low step portion 33, the portion (center 33 a) dividing the screw thread 15 and the neck ring 17 has substantially no width in the circumferential direction of the mouth and neck portion 10. . In other words, in the low step portion 33, the portion dividing the screw thread 15 and the neck ring 17 is a point in a plan view and a line in a side view, and is not a plane.
However, the low step portion 33 may be formed so that a portion of the low step portion 33 dividing the screw thread 15 has a width in the circumferential direction of the mouth-and-neck portion 10. That is, in FIG. 5A, the right lower step 33 may be dug further to the left, and the left lower step 33 may be dug further to the right.
Or the low step part 33 does not need to divide the thread 15. That is, in FIG. 5A, the low step portion 33 may be formed so that the right low step portion 33 is located on the right side and the left low step portion 33 is located on the left side.

  Of the longitudinal cross section of the bottle container 100, the first longitudinal cross section including the axis X of the mouth and neck portion 10 and passing through the screw dividing portion 31 and the second screw dividing portion 32, and the mouth and neck portion 10. For example, the second longitudinal section including the axis X and passing through the center 33a of the pair of low step portions 33 is orthogonal to each other.

  As described above, the pressing portion 50 is the end portion of the main body portion 20 on the opposite side of the groove-shaped portion 40 from the screw dividing portion 31 side, the middle portion of the groove-shaped portion 40, or on the extension of the groove-shaped portion 40. It is formed in the part. Specifically, for example, the lower end portion of the groove-like portion 40 reaches the pressing portion 50, and the pressing portion 50 is formed in a portion of the trunk portion 22 adjacent to the end portion of the groove-like portion 40. . For this reason, the press part 50 is located in the upper end of the center part in the horizontal direction of the trunk | drum 22, for example.

  In the case of this embodiment, the pressing part 50 is a recessed part. The shape of the pressing portion 50 is not particularly limited, but is preferably a shape that fits the belly of a finger (for example, a thumb) when the bottle container 100 is crushed, for example, a horizontally long elliptical shape is suitable. .

  The upper edge of the pressing portion 50 constitutes a part of the boundary line between the trunk portion 22 and the shoulder portion 21. That is, the upper edge of the pressing portion 50 constitutes a second portion 81 b that is a part of the first ridge line 81. A portion of the first ridge line 81 other than the second portion 81b is a first portion 81a. The first portion 81a and the second portion 81b may be continuous with each other or may be divided. In the example shown in FIG. 1A and the like, the first portion 81a and the second portion 81b are continuous (connected) to each other.

  Moreover, the groove-shaped part 40 and the screw parting part 31 are formed, for example, connected by a smooth curve. That is, the second groove portion of the thread dividing portion 31 includes a first end portion 31a that is an end portion of the second groove portion on the groove portion 40 side, and the groove portion 40 is the groove portion 40. Including the second end portion 40a which is the end portion on the second groove-like portion side, including the axial center X of the mouth-and-neck portion 10 and the boundary portion 35 between the first end portion 31a and the second end portion 40a. In the cross section cut along the plane, the boundary portion 35 is formed in a smooth curved shape (see FIGS. 3D, 3E, and 2A). By doing in this way, since the level | step difference and edge do not generate | occur | produce in any part in the 2nd groove-shaped part and the groove-shaped part 40, it becomes easier to crush the bottle container 100 further. That is, since the series of grooves constituting the second groove-shaped portion and the groove-shaped portion 40 do not have a portion where the extending direction changes sharply, the bottle container 100 can be smoothly and along the series of grooves. Can be crushed continuously.

  Further, the depth of the groove-like portion 40 is once deepened from the end portion (that is, the upper end portion) of the groove-like portion 40 on the screw dividing portion 31 side toward the pressing portion 50 side. It is preferable that the depth gradually decreases from the deepest portion 40b toward the pressing portion 50 (see FIG. 3E). By doing in this way, in the cross section of FIG.3 (e), the change of the extension direction of a series of groove | channels from the thread part 31 to the groove part 40 is made into the boundary of the screw part 31 and the groove part 40. The portion 35 can also be loosened. In other words, the radius of curvature at the boundary 35 can be made sufficiently large in the cross section of FIG. As a result, the boundary portion 35 between the thread dividing portion 31 and the groove-shaped portion 40 can be easily crushed, so that the bottle container 100 can be crushed more easily.

Further, on the outer surface of the main body portion 20, a side groove portion 60 is formed from the body portion 22 to the shoulder portion 21 at a portion that becomes a side surface when the portion where the groove portion 40 is formed is a front surface. Yes. That is, side groove portions 60 are formed from the body portion 22 to the shoulder portion 21 on the outer surfaces of the side surface portion 20c and the side surface portion 20d of the main body portion 20, respectively. The side groove portion 60 extends along a plane including the axis X of the mouth-and-neck portion 10 and the center 33 a of the low step portion 33.
Specifically, for example, two side surface groove portions 60 are formed in parallel to each other on one side surface portion 20 c from the body portion 22 to the shoulder portion 21. Similarly, on the other side surface portion 20d, for example, two side surface groove portions 60 are formed in parallel to each other from the body portion 22 to the shoulder portion 21.

In the side surface groove portion 60, when the portion formed in the body portion 22 is referred to as a first portion 61, the first portion 61 is formed from the upper end to the lower end of the body portion 22, for example. The groove depth of the first portion 61 is, for example, formed constant from one end of the first portion 61 to the other end.
Moreover, in the side surface groove part 60, when the part formed in the shoulder part 21 is called the 2nd part 62, the 2nd part 62 is formed ranging from the lower end of the shoulder part 21 to an upper end, for example. For example, the groove depth of the second portion 62 gradually decreases toward the mouth-neck portion 10 side. For this reason, when the bottle container 100 is molded by blow molding or the like, it can be easily released from the molding die.
Moreover, the lower end part (3rd part 63) of the side surface groove part 60 is located in the upper end part of the bottom part 23, for example.

Furthermore, on the outer surface of the main body portion 20, the shoulder portion 21 of the portion that becomes the side surface when the portion where the groove-like portion 40 is formed is the front surface is directed from the mouth-and-neck portion 10 side toward the trunk portion 22 side. An extending ridge 70 is formed. That is, of the outer surface of the side surface portion 20c and the side surface portion 20d of the main body portion 20, the shoulder portion 21 is formed with a ridge 70 extending from the mouth / neck portion 10 side toward the body portion 22 side. . The protruding height of the ridge 70 is gradually increased toward the mouth and neck 10 side.
In each of the side surface portion 20 c and the side surface portion 20 d in the shoulder portion 21, the protrusion 70 is formed at a portion sandwiched between the second portions 62 of the two side surface groove portions 60.
The upper end portion 70a of the ridge 70 is located at, for example, the lower end portion of the mouth / neck portion 10 (the lower end portion of the large diameter portion 11).

  Note that, in each of the side surface portion 20 c and the side surface portion 20 d in the body portion 22, the intermediate portion 65 sandwiched between the two side surface groove portions 60 protrudes relative to the side surface groove portions 60. Therefore, it is substantially like a ridge. As shown in FIG. 1B and the like, for example, the ridge 70 and the intermediate portion 65 are positioned in a straight line with each other in a side view and are connected to each other.

  The bottle container 100 is configured as described above.

Next, the bottle container stuffed product 200 shown in FIG. 6 will be described in detail.
The bottle container stuffed product 200 includes the bottle container 100 described above, the contents 160 accommodated in the bottle container 100, and the lid portion 153 attached to the mouth / neck portion 10 of the bottle container 100.

The form of the content 160 is not limited to a liquid form (including a paste form), but may be a solid form (for example, a granular form (including a granular form) or a powder form). .
The type of the content 160 is not particularly limited. Examples of the contents 160 include liquid soap (hand soap, body soap), shampoo, rinse, detergent, food, and the like.

  When the content 160 is liquid, for example, the content 160 having a viscosity at 30 ° C. of 500 to 50,000 mPa · s (measured with a B-type viscometer) is accommodated in the bottle container 100.

  Here, as an example, an example will be described in which the content 160 is a liquid hand soap and the bottle container-filled product 200 includes a dispenser pump 150 attached to the mouth and neck portion 10.

  As the dispenser pump 150, a pump having a known structure can be used. The dispenser pump 150 includes a type that discharges the liquid content 160 in the form of bubbles and a type that discharges while the liquid content 160 is in a liquid state.

  The dispenser pump 150 includes a screw-type lid portion 153 attached to the mouth-and-neck portion 10, a pump portion 156 provided integrally with the lid portion 153, a conduit portion 157 communicating with the pump portion 156, and a user. An operation unit 151 that is pushed in and a discharge unit 152 that discharges the contents 160 are provided.

The lid portion 153 is formed in a cylindrical shape that is open at the lower end side and closed at the upper end side to form the top surface portion. The inner peripheral surface of the lid portion 153 is formed in a female screw shape that is screwed into the mouth / neck portion 10. That is, a thread 155 that protrudes inward is formed on the inner peripheral surface of the lid 153. The dispenser pump 150 is attached to the bottle container 100 by screwing the lid portion 153 with the mouth neck portion 10. Further, an annular seal portion 154 is provided on the inner surface of the top surface portion of the lid portion 153, and the upper end surface of the small diameter portion 13 of the mouth-and-neck portion 10 with the dispenser pump 150 attached to the bottle container 100. It abuts against the seal portion 154.
The conduit portion 157 and the discharge portion 152 communicate with each other through the pump portion 156, the top surface portion of the lid portion 153, and the operation portion 151.

  The operation part 151 is pushed downward against the bias of a spring (not shown) built in the pump part 156, and the push part is released, whereby the contents 160 in the bottle container 100 are connected to the conduit by the action of the pump part 156. The contents 160 are sucked up through the section 157, and the contents 160 are discharged from the discharge section 152 by a specified amount. By releasing the force that pushes the operation unit 151 downward after discharging, the operation unit 151 is raised to the original position in accordance with the bias of the spring.

  Here, the example of the preferable range of the dimension ratio of each part in case the bottle container 100 is produced with synthetic resins, such as polyethylene, is demonstrated.

The ratio (W1: D1) between the width W1 (FIG. 5 (a)) and the depth D1 (FIG. 5 (a)) at the open end of the screw dividing portion 31 (the position of the top of the thread 15) is 5: A range of 1 to 1: 1 is preferred. By setting W1: D1 in such a range, the force to return the mouth and neck 10 when it is crushed can be suppressed, so that the mouth and neck 10 can be easily maintained in a crushed state. It becomes easy to attach the cover part 153. Moreover, since the rigidity of the screw parting part 31 can be moderately suppressed, the mouth-and-neck part 10 is easily crushed.
Similarly, the ratio (W2: D1) of the width W2 (FIG. 5 (a)) and the depth D1 (FIG. 5 (a)) at the bottom of the thread dividing portion 31 is also 5: 1 to 1: 1. It is preferable to be in the range.

  The ratio (W1: W2) of the width W1 at the opening end of the thread dividing portion 31 to the width W2 at the bottom is preferably in the range of 7: 1 to 1: 1. By setting W1: W2 in such a range, it is possible to suppress a force to return the mouth and neck 10 when the mouth and neck 10 are crushed, so that the mouth and neck 10 can be easily maintained in a crushed state. It becomes easy to attach the cover part 153. Further, the bottle container 100 can be easily formed.

  The ratio (Φ: W1) between the inner diameter Φ of the neck 10 (FIG. 5A) and the width W1 at the open end of the thread dividing portion 31 is preferably in the range of 2: 1 to 11: 1. . By setting Φ: W1 in such a range, it is possible to suppress the force to return the mouth and neck 10 when the mouth and neck 10 are crushed, so that the mouth and neck 10 can be easily maintained in a crushed state. Since the rigidity can be moderately suppressed, the mouth and neck portion 10 is easily crushed.

  The ratio (Φ: D1) of the inner diameter Φ of the mouth / neck portion 10 to the depth D1 of the screw dividing portion 31 is preferably in the range of 40: 1 to 6: 1. By setting Φ: D1 in such a range, it becomes easy to maintain the mouth-and-neck portion 10 in a crushed state, and the rigidity of the screw dividing portion 31 can be moderately suppressed, so that the mouth-and-neck portion 10 is easily crushed.

  It is preferable that the ratio (thickness: depth) of the thickness of the mouth / neck portion 10 and the depth D1 of the screw dividing portion 31 is in the range of 1: 4 to 1: 1. By setting the ratio of the thickness of the mouth / neck portion 10 and the depth D1 of the screw dividing portion 31 to such a range, the rigidity of the screw dividing portion 31 can be moderately suppressed. It becomes easy to attach the lid 153 to the neck 10.

  Further, the second screw dividing portion 32 can be formed with the same dimensional ratio as that of the first screw dividing portion 31.

  For the groove 40, at the upper end of the groove 40, the ratio of the width and depth at the opening end, the ratio of the width and depth at the bottom, and the ratio of the width at the opening and the width at the bottom. Can be formed at the same dimensional ratio as in the first thread dividing portion 31.

Moreover, about the protruding item | line 70, it is preferable to make the height into below that width. By doing so, since the rigidity of the stepped portion formed by the ridges 70 can be suppressed, the bottle container 100 can be easily crushed.
Further, the maximum width of the ridge 70 is set to be 1 to 4 times the minimum width of the ridge 70, whereby the bottle container 100 can be smoothly bent and deformed along the ridge 70.
In addition, it is preferable that the protruding item | line 70 is extended so that the lower end of the low step part 33 and the 1st ridgeline 81 may be connected.

Moreover, it is preferable that the width | variety (width | variety in an opening end) of the side surface groove-shaped part 60 is 4 mm or more and 15 mm or less. By setting the width of the side groove portion 60 in such a range, the bottle container 100 can be easily maintained in a crushed state.
The depth of the side groove portion 60 can be appropriately set according to the width of the side groove portion 60.
The width of the intermediate portion 65 is preferably set to be equal to the width of the ridge 70.

  The dimensions of the other parts of the bottle container 100 can be set as appropriate according to the size of the bottle container 100.

  Next, the operation of crushing and folding the bottle container 100 of the bottle container-packed product 200 will be described.

  When the contents 160 of the bottle container stuffed product 200 are used up, the dispenser pump 150 is first removed from the bottle container 100. Next, in order to crush the bottle container 100, the user holds the bottle container 100 by hand.

  Here, a pressing portion 50 that is a concave portion is formed on the back surface portion 20 b of the bottle container 100, and the groove portion 40 extends toward the pressing portion 50, and a screw is provided on the extension of the groove portion 40. A dividing portion 31 is also formed. For this reason, the user can easily recognize that the bottle container 100 can be crushed smoothly by pressing the pressing portion 50. For this reason, for example, the user holds the bottle container 100 with both hands so that the user can easily press the pressing portion 50, and puts the thumbs of both hands against the pressing portion 50, and the side portions 20c and 20d and the front surface with the palm and the remaining fingers. Supports part 20a.

  Next, the pressing part 50 is pressed with the thumbs of both hands, and the bottle container 100 is crushed (see FIG. 7A). At this time, since the pressing portion 50 is a concave portion, the finger sits well against the pressing portion 50 and the pressing portion 50 is easily pushed. Moreover, since the press part 50 is a recessed part formed beforehand, the main-body part 20 can be crushed smoothly by enlarging the depth and area of the recessed part.

  By pressing the pressing portion 50, the back surface portion 20b is recessed toward the front surface portion 20a, and the volume of the bottle container 100 is reduced. At this time, the back surface portion 20b of the shoulder portion 21 along the groove portion 40 is easily bent into a valley fold shape (V-shape) (see FIG. 8B), and the shoulder portion 21 is crushed. Further, since the shoulder portion 21 and the mouth and neck portion 10 are adjacent to each other, the mouth and neck portion 10 is also crushed as the shoulder portion 21 is crushed. Further, by directly pressing the mouth and neck part 10 with a finger so that the screw part 31 is closer to the second screw part 32 side, the mouth and neck part 10 can be sufficiently crushed as shown in FIG. it can.

  In this way, a series of crushing operations from the main body 20 to the mouth and neck 10 can be performed easily and smoothly.

  Here, the mouth and neck portion 10 is formed with a screw dividing portion 31, a second screw dividing portion 32, and a pair of low step portions 33. For this reason, the mouth-and-neck part 10 bends mainly at the center 33 a of the screw dividing part 31, the second screw dividing part 32, and the pair of low step parts 33. Specifically, for example, as shown in FIG. 8A, for example, the screw dividing portion 31 and the second screw dividing portion 32 are each bent into a valley fold shape, and the centers 33a of the pair of low step portions 33 are respectively peaks. Bends into a folded shape. For this reason, the shape when the mouth-and-neck portion 10 is viewed from the opening 10a side in the axial center X direction is, for example, a shape in which a figure 8 is bent (FIG. 8A).

  In the mouth and neck portion 10, not only the screw dividing portion 31 but also the second screw dividing portion 32 is formed, so that the second portion at the final stage of the operation of pushing the screw dividing portion 31 into the second screw dividing portion 32 side or the like. Since the screw parting portion 32 is deformed, the mouth and neck portion 10 can be flattened more easily and sufficiently.

  The centers 33 a of the screw parting portion 31, the second screw parting part 32, and the low step part 33 extend in parallel with the axis X of the mouth-and-neck part 10. That is, the center 33a of each of the screw dividing portion 31, the second screw dividing portion 32, and the low step portion 33 extends linearly, so that the mouth and neck portion 10 is connected to the screw dividing portion 31 and the second screw dividing portion 32. And it can bend more smoothly along the center 33a of the low step portion 33.

Here, the groove part 40 is formed in the main body part 20, and when the main body part 20 is crushed, the main body part 20 is valley-folded along the groove part 40, and thus the groove part 40 exists. Compared with the case where it does not, it is easy to crush the main-body part 20, and the valley fold state is easy to be hold | maintained. That is, since the bottle container 100 has the groove-shaped portion 40 having a simple structure, the bottle container 100 is easily crushed and easily held in a crushed state.
In addition, when the groove-shaped portion 40 is not formed, it is easier to return elastically after the main body portion 20 is crushed than when the groove-shaped portion 40 is formed, and thus it is difficult to maintain the crushed state. .

  Moreover, since the screw parting part 31 and the groove-shaped part 40 are mutually connected, a series of crushing operation | movement from the main-body part 20 to the mouth neck part 10 can be performed much more smoothly and continuously. Moreover, since the screw parting part 31 and the groove-like part 40 are connected to each other, the deformation of the main body part 20 can be smoothly transmitted to the mouth-and-neck part 10, so that the mouth-and-neck part 10 can be obtained simply by crushing the main body part 20. Also, the time required for the crushing operation of the bottle container 100 can be shortened.

  Moreover, since the screw parting portion 31 is formed in a groove shape that is recessed from the screw groove 16, the mouth and neck part 10 can be more reliably bent into the valley fold shape along the screw parting portion 31.

Further, as described above, the first ridge 81 is formed in the bottle container 100. As shown by the one-dot chain line in FIG. 7A, in the state before the bottle container 100 is crushed, the portion in the vicinity of the first ridge line 81 in the main body 20 protrudes outward from the main body 20. It is the shape of.
On the other hand, as shown by a solid line in FIG. 7A, in the state after the bottle container 100 is crushed, the portion in the vicinity of the first ridgeline 81 on the back surface portion 20 b of the main body portion 20 is A convex shape is formed inward. That is, the protruding direction of the shape of the portion in the vicinity of the first ridgeline 81 on the back surface portion 20b of the main body portion 20 is reversed before and after the bottle container 100 is crushed.
And after the bottle container 100 is crushed in this way, it becomes a convex shape inward (inverted), so that the portion in the vicinity of the first ridgeline 81 on the back surface portion 20b of the main body portion 20 is: It becomes easier to retain the shape in a crushed state. That is, the main body 20 is in a locked state so that the collapsed state is maintained.
Therefore, the bottle container 100 is easier to hold the crushed state by the first ridgeline 81.
In particular, since the first ridge line 81 is formed in a wavy line shape, the first ridge line 81 is more securely held as described above than in the case where the first ridge line 81 is formed horizontally. easy.

In addition, since the side surface groove portions 60 are formed on the side surface portions 20c and 20d of the main body portion 20, the main body portion 20 can be easily bent along the side surface groove portion 60, and the main body portion 20 can be bent. It can be crushed more easily.
In particular, since each of the side surface portions 20c and 20d has two side surface groove portions 60 formed in parallel with each other, the intermediate portion 65 positioned between the two side surface groove portions 60 has a side surface groove. The protrusions are relatively raised with respect to the shape portion 60. Therefore, the main body portion 20 can be crushed by bending the main body portion 20 along the side groove portions 60 on both sides using the intermediate portion 65 as a guide. That is, it is possible to easily realize a mountain fold shape in which the intermediate portion 65 is a ridge.
Moreover, since the side surface groove-shaped part 60 is formed ranging from the upper end to the lower end of the trunk | drum 22, it can crush the trunk | drum 22 from the upper end to the lower end easily.

Moreover, since the protruding item | line 70 is formed in the side parts 20c and 20d of the shoulder part 21 of the main-body part 20, it is made to bend the shoulder part 21 along the protruding item | line 70 by using the protruding item | line 70 as a guide. The shoulder portion 21 can be easily crushed. That is, a mountain fold shape in which the convex portion 70 becomes a ridge can be easily realized. Since the ridge 70 is formed at a portion sandwiched between the second portions 62 of the two side surface groove portions 60, the both side portions of the ridge 70, that is, the second portion 62 of the side surface groove portion 60. , The shoulder 21 can be bent more easily and the shoulder 21 can be crushed.
Further, the depth of the second portion 62 of the side groove portion 60 in the shoulder portion 21 is gradually shallower toward the mouth neck portion 10 side, while the protruding height of the ridge 70 is the mouth neck portion 10. Since the height is gradually increased toward the side, it is possible to suppress a change in the height difference between the ridge 70 and the second portion 62 of the side groove portion 60. As a result, the shoulder portion 21 can be easily deformed and crushed from the mouth / neck portion 10 side to the trunk portion 22 side.

  After finishing the first stage crushing as shown in FIG. 7 (a), FIG. 8 (a), (b), for example, by performing the second stage crushing as shown in FIG. The volume of the container 100 can be further reduced. That is, for example, the bottom portion 23 is crushed and the bottom portion 23 is folded so that the bottom portion 23 covers the back surface portion 20b, whereby the bulk of the bottom portion 23 is increased. Can be suppressed.

  In this way, the bottle container 100 can be crushed and its volume can be reduced, so that the bottle container 100 can be prevented from becoming bulky when discarded after use, and the volume of waste can be reduced. Can do.

According to the embodiment as described above, on the outer peripheral surface of the mouth-and-neck portion 10, the screw dividing portion 31 formed by dividing the screw thread 15 extends in parallel with the axis X of the mouth-and-neck portion 10. A groove-like portion 40 is formed on the outer surface of the main body 20 so as to extend in the extending direction of the screw dividing portion 31 when the screw dividing portion 31 is viewed from the front.
And the press part 50 which shows the press position at the time of crushing the bottle container 100 is formed in the main-body part 20, The press part 50 is the edge part on the opposite side to the screw parting part 31 side in the groove-shaped part 40. In the middle of the groove-like portion 40 or an extension of the groove-like portion 40. Therefore, by pressing the pressing portion 50 and crushing the main body portion 20, the deformation can be smoothly transmitted to the groove-shaped portion 40, and the main body portion 20 can be deformed along the groove-shaped portion 40. That is, since the pressing portion 50 is disposed at a position suitable for pressing and crushing the main body portion 20, the main body portion 20 is easily deformed along the groove-shaped portion 40 by pressing the pressing portion 50. Can be crushed.
And when crushing the main-body part 20, since the groove-shaped part 40 becomes a valley fold shape easily, the main-body part 20 can be crushed easily. Furthermore, since the screw parting portion 31 exists on the extension of the groove-like part 40, the main body part 20 can be crushed and the mouth-and-neck part 10 can be easily crushed by being folded into a valley fold along the screw parting part 31. Therefore, the part from the main-body part 20 to the mouth neck part 10 can be crushed easily.
In addition, when the bottle container 100 is crushed, the main body portion 20 is valley-folded along the groove-shaped portion 40, so that the valley-folded state is easily maintained as compared with the case where the groove-shaped portion 40 is not present. That is, since the bottle container 100 has the groove-shaped portion 40 with a simple structure, the bottle container 100 is not only easily crushed but also easily held in a crushed state.
As described above, it is possible to easily crush the portion from the main body portion 20 to the mouth neck portion 10 and to easily maintain the crushed state with a simple structure.

In the technique of Patent Document 1, as described above, the main body portion is not structured so as to facilitate crushing except for the bottom portion, and therefore a series of crushing operations from the main body portion to the mouth and neck portion. It is considered that it is not always easy to carry out smoothly.
Furthermore, in the technique of Patent Document 1, in order to maintain the state in which the container is crushed, a concave portion is provided on one opposing surface of the container, and a convex portion that can be fitted to the concave portion on the other opposing surface. Are formed. For this reason, processing of a complicated shape is required at the time of molding of the container, and the inner volume is reduced for the bulk of the container. Moreover, since many unevenness | corrugations are formed in the inner surface of a container, the residue of the content in a container will also arise easily.

  On the other hand, according to the bottle container 100 according to the present embodiment, since the groove-shaped portion 40 and the screw dividing portion 31 are formed, a series of crushing operations from the main body portion 20 to the mouth-and-neck portion 10 is smoothly performed. It can be carried out. In addition, since the bottle container 100 does not have a fitting structure for holding the crushed state, the bottle container 100 can be made a simple structure, the bottle container 100 can be easily molded, and the bottle Residue of the content 160 in the container 100 can be suppressed, and the content 160 can be used up efficiently. Moreover, it is easy to ensure a large inner volume of the bottle container 100 as much as possible.

  Further, according to the bottle container 100 according to the present embodiment, the main body portion 20 is formed with the pressing portion 50 indicating the pressing position when the bottle container 100 is crushed. The part from the part 20 to the mouth and neck part 10 can be easily crushed.

In addition, the thread dividing portion 31 is a second groove-shaped portion formed in a groove shape in which at least the groove-shaped portion 40 side is recessed from the screw groove 16, and the second groove-shaped portion and the groove The shape portion 40 is formed in a groove shape continuous with each other.
Therefore, the mouth-and-neck portion 10 can be more reliably bent into a valley fold shape along the second groove-shaped portion of the screw dividing portion 31.
Further, since the second groove-shaped portion and the groove-shaped portion 40 of the screw dividing portion 31 are formed in a continuous groove shape, a series of crushing operations from the main body portion 20 to the mouth neck portion 10 are smoother. And continuously. In addition, since the deformation of the main body 20 can be smoothly transmitted to the mouth-and-neck portion 10, it can be expected that the mouth-and-neck portion 10 is also crushed to some extent by simply crushing the main body portion 20.

Further, the second groove-shaped portion of the screw dividing portion 31 includes a first end portion 31a that is an end portion on the groove-shaped portion 40 side in the second groove-shaped portion, and the groove-shaped portion 40 is the groove-shaped portion 40. The second end portion 40a that is the end portion on the second groove-like portion side is included. And in the cross section cut | disconnected by the plane containing the axial center X of the mouth-and-neck part 10, and the boundary part 35 of the 1st end part 31a and the 2nd end part 40a, the boundary part 35 is formed in the smooth curve shape. ing.
Thereby, since a level | step difference and an edge do not generate | occur | produce in any part in the 2nd groove-shaped part and the groove-shaped part 40, it becomes easy to crush the bottle container 100 further.

  Moreover, since the depth of the groove-shaped part 40 once becomes deep from the edge part by the side of the screw parting part 31 in the said groove-shaped part 40 toward the press part 50 side, it becomes shallow gradually, Therefore The bottle container 100 It becomes easier to crush.

  Moreover, since the pressing part 50 is a recessed part, the sitting of the finger with respect to the pressing part 50 is good, the pressing part 50 is easy to be pushed in, and the depth and area of the recessed part are expanded, so that the main body part 20 is smoothly crushed. be able to.

  Further, on the outer peripheral surface of the mouth-and-neck portion 10, a second screw-splitting portion 32 formed by dividing the screw thread 15 is provided at a location facing the screw-splitting portion 31 across the axis X of the mouth-and-neck portion 10. It is formed so as to extend in parallel with the dividing portion 31. Therefore, the mouth / neck portion 10 can be easily bent along the second screw dividing portion 32, so that the degree of freedom of deformation of the mouth / neck portion 10 is improved. Therefore, compared with the case where there is no 2nd screw parting part 32, while the mouth neck part 10 can be crushed more easily and flatly, the crushed state can be hold | maintained more easily.

  Further, on the outer peripheral surface of the mouth-and-neck portion 10, the thread 15 is formed at a lower level than the surrounding portion or divided in each of the portions that become side surfaces when the portion where the screw dividing portion 31 is formed is the front surface. As a result, a low step portion 33 is formed. Therefore, since the mouth and neck part 10 can be easily bent at the low step part 33, the degree of freedom of deformation of the mouth and neck part 10 is further improved. Therefore, compared with the case where there is no low step part 33, while the mouth neck part 10 can be crushed more easily and flatly, the crushed state can be hold | maintained more easily.

  Further, the distance from the axis X of the mouth-and-neck portion 10 to the screw groove 16 is equal to the distance from the axis X to the low step portion 33. Therefore, the gap between the screw thread (for example, screw thread 155) of the lid (the lid part 153, etc.) attached to the mouth / neck part 10 and the low step part 33 can be suppressed as much as possible, so the low step part 33 is formed. It is possible to suppress a decrease in sealing performance.

  Further, on the outer surface of the main body portion 20, a side groove portion 60 is formed from the body portion 22 to the shoulder portion 21 at a portion that becomes a side surface when a portion where the groove portion 40 is formed is a front surface. Therefore, the main body portion 20 can be easily bent along the side groove portion 60. Therefore, the main body 20 can be crushed more easily.

  Further, two side surface groove portions 60 are formed in parallel to each other from the body portion 22 to the shoulder portion 21, and a portion of the shoulder portion 21 sandwiched between the two side surface groove portions 60 has a mouth. A ridge 70 extending from the neck 10 side toward the body 22 side is formed. Therefore, it is possible to more easily bend the shoulder 21 along the portions on both sides of the ridge 70, that is, the second portion 62 of the side groove portion 60, and crush the shoulder 21.

  Moreover, in the outer surface of the main body portion 20, the shoulder portion 21 of the portion that becomes the side surface when the portion where the groove-like portion 40 is formed is the front surface is directed from the mouth and neck portion 10 side toward the trunk portion 22 side. An extending ridge 70 is formed. Therefore, even if the main body 20 is thin, the deformation of the ridge 70 itself is suppressed, so that the shoulder 21 is bent along the ridge 70 using the ridge 70 as a guide. 21 can be easily crushed.

In addition, a first ridge line 81 extending along the circumferential direction of the main body 20 is formed at the boundary between the shoulder 21 and the body 22. Therefore, in a state after the bottle container 100 is crushed, a portion in the vicinity of the first ridge line 81 on the crushed surface of the main body portion 20 has a convex shape (outer side) toward the inner side of the main body portion 20. It becomes concave toward the direction). That is, the protruding direction of the shape of the portion is reversed before and after the bottle container 100 is crushed. Therefore, the portion is easily held in a crushed state.
In addition, the presence of the first ridgeline 81 and the second ridgeline 82 improves the rigidity of the bottle container 100 and can also improve the shape retention during use, storage, transportation, and the like.

Further, a first ridge line 81 extending along the circumferential direction of the main body portion 20 is formed at the boundary portion between the shoulder portion 21 and the body portion 22, and the groove-like portion 40 is formed in the shoulder portion 21 at the mouth and neck. The first ridge line 81 extends from the boundary with the part 10. A pressing portion 50 that is pressed when the bottle container 100 is crushed is formed in a portion adjacent to the end portion of the groove-shaped portion 40 in the body portion 22, and a boundary portion between the pressing portion 50 and the shoulder portion 21 is the first portion. A part of the one ridge line 81 (second portion 81b) is formed.
Thus, since the groove-shaped part 40 is extended toward the 1st ridgeline 81, the main-body part 20 can be deform | transformed along the groove-shaped part 40 more reliably by pressing the press part 50. FIG. it can. Moreover, since the boundary part of the press part 50 and the shoulder part 21 comprises a part (2nd part 81b) of the 1st ridgeline 81, by pressing the press part 50, a 1st ridgeline is ensured. 81 can be inverted as described above so that the crushed state can be maintained.

Next, a modified example of the bottle container 100 will be described.

The bottle container 100 according to the first modification is different from the bottle container 100 according to the above-described embodiment in that the screw dividing part 31 and the second screw dividing part 32 are not formed in a groove shape. It is comprised similarly to the bottle container 100 which concerns on said embodiment.

  In the first modification, the thread dividing portion 31 is formed in a curved shape along the outer peripheral surface of the large-diameter portion 11 of the mouth-and-neck portion 10. That is, the thread dividing portion 31 is formed in a shape in which the thread 15 is partially removed to the same height as the thread groove 16.

  Although not shown, the second screw dividing portion 32 is also formed in a shape in which the screw thread 15 is partially removed to the same height as the screw groove 16, similarly to the screw dividing portion 31.

  Even in the first modification, since the groove portion 40 is provided as in the above-described embodiment, the same effect as in the above-described embodiment can be obtained.

<Modification 2>
FIG. 9B is a view showing the upper back of the bottle container 100 according to the second modification. The bottle container 100 according to the first modified example is different from the bottle container 100 according to the above-described embodiment in that the screw dividing part 31 and the groove-like part 40 are not connected to each other. It is comprised similarly to the bottle container 100 which concerns on embodiment.

  Also in the case of this modification, when the screw dividing portion 31 is viewed from the front, the screw dividing portion 31 and the groove-like portion 40 are arranged so that the screw dividing portion 31 and the groove-like portion 40 exist on the same straight line. Preferably it is. In other words, the groove-like portion 40 preferably extends along a plane including the axis X of the mouth-and-neck portion 10 and the screw dividing portion 31.

  Even in the second modified example, since the groove-like portion 40 is provided, the same effect as that of the above embodiment can be obtained.

<Modification 3>
FIGS. 10A and 10B are diagrams showing a bottle container 100 according to the modified example 3, in which (a) is a plan view, (b) is a front view, (c) is a bottom view, and (d) is a D- of (b). It is a cut end view along the D line. The bottle container 100 according to the present modified example is different from the bottle container 100 according to the above-described embodiment in that it has a pedestal portion 18, and is otherwise configured in the same manner as the bottle container 100 according to the above-described embodiment. ing.

  The pedestal 18 is formed as an upward step surface at the upper end of the shoulder 21. The pedestal portion 18 is formed in an annular shape so as to surround the mouth and neck portion 10 in plan view.

Further, the pedestal portion 18 is also divided at the portion where the side groove portions 60 and the upper ends of the ridges 70 are located (the pedestal portion 18 does not exist).

  In the case of this modification, since the bottle container 100 has the pedestal portion 18, when the lid portion is attached to the mouth / neck portion 10, a gap is generated between the lower end surface of the lid portion and the main body portion 20. It can suppress and the appearance of the bottle container 100 can be improved.

  Even in the third modified example, the same effect as the above-described embodiment can be obtained. That is, even when it has the base part 18 like the modification 3, the bottle container 100 can be crushed easily by having the structure of embodiment mentioned above.

In each of the above-described embodiments and modified examples, the example in which the screw dividing portion 31 extends in parallel with the axis X of the mouth-and-neck portion 10 has been described, but the present invention is not limited to this example.
For example, the screw parting portion 31 may be formed in a meandering shape along a line parallel to the axis X. Also in this case, the screw parting portion 31 extends in parallel with the axis X. In this case, it is preferable that the screw parting portion 31 has a width that includes at least a straight line parallel to the axis X. By doing so, the mouth and neck part 10 can be easily crushed.
Alternatively, the depth of the thread dividing portion 31 may vary in the longitudinal direction. For example, for example, the depth of the screw dividing portion 31 may be deepened downward, may be shallow, or deep portions and shallow portions may be alternately repeated.

  Similarly, the second thread dividing portion 32 may be formed in a meandering shape along a line parallel to the axis X, or the depth may vary in the longitudinal direction.

Moreover, in the above, the example in which the groove-like part 40 was formed by one continuous groove over the entire length thereof was described. However, the groove-shaped portion 40 may be configured by a plurality of portions (a plurality of groove-shaped portions) formed discontinuously with each other. That is, the groove-like portion 40 may be composed of a plurality of portions that are intermittently arranged along the extending direction of the screw dividing portion 31 when the screw dividing portion 31 is viewed from the front.
Moreover, in this case, it is preferable that the portion closest to the screw dividing portion 31 among the plurality of portions of the groove-like portion 40 is connected to the screw dividing portion 31. A series of crushing operations over the neck 10 can be performed smoothly.

  In the above description, the first ridge line 81 and the second ridge line 82 are formed in a wavy shape that undulates in the vertical direction. However, the first ridge line 81 and the second ridge line 82 are horizontal. (In a straight line in front view, back view, side view, etc.).

Further, when the bottle container 100 is produced by blow molding, it is also necessary to control the thickness of each part of the bottle container 100 by appropriately adjusting the thickness of each part in the parison used for blow molding. Can be done according to.
For example, the main body 20 can be easily crushed by forming the main body 20 thinner than the mouth-and-neck 10.
Further, by forming the body portion 22 to be thinner than the shoulder portion 21 and the bottom portion 23 in the body portion 20, the body portion 20 can be crushed more easily.
Moreover, you may vary the thickness of each part in the circumferential direction of the main-body part 20 as needed. In this case, by forming the back surface portion 20b and the front surface portion 20a thinner than the side surface portions 20c and 20d, the back surface portion 20b and the front surface portion 20a can be easily deformed and the main body portion 20 can be easily crushed.
On the other hand, by forming the side surface portions 20c and 20d thinner than the back surface portion 20b and the front surface portion 20a, it is possible to reduce the force that the side surface portions 20c and 20d attempt to return elastically after being crushed. The maintained state can be easily performed.

  Further, the bottle container 100 may not have the neck ring 17.

Moreover, in the above, although the example in which the pressing part 50 was a recessed part was demonstrated, the pressing part 50 may be a convex part. Also in this case, the user can easily recognize that the pressing unit 50 should be pressed when the bottle container 100 is crushed.
Further, the pressing portion 50 may be a portion with a mark (not shown) indicating that the pressing portion 50 is a portion that is pressed when the bottle container 100 is crushed. For example, the mark is printed on the main body 20, or a label (not shown) on which the mark is printed is attached to the main body 20. Also in this case, the user can easily recognize that the pressing unit 50 should be pressed when the bottle container 100 is crushed.
