Description

The present invention relates to a container, and more specifically to a container having a cap.

As an example of this type of prior art, Patent Document 1 discloses a container including a container body and a cap. A spiral spiral ridge is formed on the outer peripheral surface of the container mouth portion of the container body. Then, between the screwed ridges and the screwed ridges, a loosening prevention ridge for preventing the cap from loosening is formed substantially horizontally on the outer peripheral surface of the container mouth portion. On the other hand, on the inner peripheral surface of the cap, a screwed ridge to be screwed with the screwed ridge is formed. The screwed ridges are formed intermittently rather than a single continuous spiral ridge. When such a cap is put on the container mouth and rotated, the screwed ridges enter between the screwed ridges, the screwed ridges slide with the screwed ridges as a guide, and the cap closes. To go. Then, the screwed ridge rides on the loosening prevention ridge formed between the screwed ridges. When the screwed ridge gets over the loosening prevention ridge, the cap is closed. By forming the anti-loosening ridge, it is possible to regulate the screwed ridge from returning in the opposite direction due to vibration or the like, and it is possible to prevent the cap from being inadvertently loosened.

Japanese Patent No. 2963678

In the container shown in Patent Document 1, in order for the screwed ridge to get over the locking ridge, the cap must be rotated to move the screwed ridge below the locking ridge. At least from the state where the lower end of the screwed ridge is in contact with the upper side of the locking ridge until the upper end of the screwed ridge is located below the lower end of the locking ridge. The threaded ridge must be moved downwards. That is, the screwed ridge must be moved downward by at least the sum of the vertical dimension of the screwed ridge and the vertical dimension of the anti-loosening ridge. Here, since the screwed ridge is formed in a spiral shape, the dimension of the screwed ridge in the vertical direction becomes large. Therefore, the amount of movement of the cap in the vertical direction required for the screwed ridge to get over the loosening prevention ridge is also large. Therefore, the amount of rotation when attaching and detaching the cap becomes large, and the operability is not good.

Therefore, a main object of the present invention is to provide a container in which the cap can be easily attached to and detached from the container body.

In order to achieve the above-mentioned object, a container body having a body portion and a mouth portion extending in a tubular shape from the body portion, and a cap attached to and detached from the mouth portion are provided, and the mouth portion is first fitted to the outer peripheral surface of the mouth portion. The cap has a second fitting portion that can be fitted with the first fitting portion on the inner peripheral surface facing the outer peripheral surface of the mouth portion, and the first fitting portion has the diameter of the mouth portion. It has a first convex portion, a second convex portion, and a third convex portion that project outward in the direction, and the second fitting portion is inward in the radial direction of the cap so as to correspond to the first convex portion. The fourth convex portion that protrudes, the fifth convex portion that protrudes inward in the radial direction of the cap so as to correspond to the second convex portion, and the fifth convex portion that protrudes inward in the radial direction of the cap so as to correspond to the third convex portion. One of the first convex portion and the fourth convex portion is formed in a straight line extending in the circumferential direction of the mouth when the cap is attached to the mouth, and the other is formed. When the cap is attached to the mouth, it is formed in a point shape or a straight line extending in the same direction as one of the caps, and the fourth convex portion is located on the side opposite to the body of the first convex portion in the axial direction of the mouth. It is possible to move from the open position to the closed position located on the body side of the first convex portion, and at least one of the second convex portion and the fifth convex portion is the mouth when the cap is attached to the mouth portion. The first direction side in the circumferential direction of the portion is formed so as to approach the body portion, and when the cap is rotated in the first direction from the state where the fourth convex portion is in the open position, the fifth convex portion slides along the second convex portion. When the 4th convex portion is in the open position, the 5th convex portion is located behind the front end portion of the 2nd convex portion in the first direction so that the 4th convex portion can move to the closed position. At least one of the third convex portion and the sixth convex portion is formed so that the first direction side approaches the body portion when the cap is attached to the mouth portion, and the cap is formed from the state where the fourth convex portion is in the closed position. The fourth convex portion is in the closed position so that the sixth convex portion slides along the third convex portion and the fourth convex portion can move to the open position when the is rotated in the direction opposite to the first direction. In the state, a container is provided in which the sixth convex portion is located anterior to the rear end portion of the third convex portion in the first direction.

According to the present invention, when the cap is rotated in the first direction to move the fourth convex portion from the open position to the closed position (when the cap is attached to the mouth portion of the container body), the fifth convex portion is used. By sliding along the second convex portion, the fourth convex portion is moved to the body side. At this time, the larger the amount of rotation of the cap, the larger the amount of movement of the fourth convex portion in the axial direction of the mouth portion toward the body portion. Here, either one of the first convex portion and the fourth convex portion is formed so as to be a linear shape extending in the circumferential direction of the mouth portion, and the other is formed to be a point shape or a linear shape extending in the same direction as one. Will be done. Therefore, the dimensions of the first convex portion and the dimensions of the fourth convex portion can be reduced in the axial direction of the mouth portion. Therefore, in the axial direction of the mouth portion, the amount of movement required for the fourth convex portion to move from the open position toward the body side, overcome the first convex portion, and move to the closed position is reduced. it can. As a result, the amount of rotation of the cap required for the fourth convex portion to move from the open position to the closed position can be reduced. In addition, the cap can be attached to the mouth just by pushing the cap like the overcap type.

When the cap is rotated in the direction opposite to the first direction to move the fourth convex portion from the closed position to the open position (when the cap is removed from the mouth of the container body), the sixth convex portion is changed to the third convex portion. By sliding along the portion, the fourth convex portion is moved to the side opposite to the body portion. At this time, the larger the amount of rotation of the cap, the larger the amount of movement of the fourth convex portion in the axial direction of the mouth portion to the side opposite to the body portion. Here, as described above, one of the first convex portion and the fourth convex portion is formed in a linear shape extending in the circumferential direction of the mouth portion, and the other is a point shape or a linear shape extending in the same direction as one. Is formed to be. Therefore, the dimensions of the first convex portion and the dimensions of the fourth convex portion can be reduced in the axial direction of the mouth portion. Therefore, in the axial direction of the mouth portion, the movement required for the fourth convex portion to move from the closed position toward the opposite side of the body, to overcome the first convex portion, and to move to the open position. The amount can be reduced. As a result, the amount of rotation of the cap required for the fourth convex portion to move from the closed position to the open position can be reduced.

In this way, the amount of operation of the cap when attaching and detaching the cap to and from the container body can be reduced, and the cap can be easily attached to and detached from the container body.

Preferably, it includes at least one of a plurality of first fitting portions formed on the outer peripheral surface of the mouth portion and a plurality of second fitting portions formed on the inner peripheral surface of the cap. When attaching to the mouth of the container body with the cap removed, it is necessary to first cover the mouth with the cap and position the 4th convex part on the opposite side (open position) of the body of the 1st convex part. There is. If the fourth convex portion is not located in the open position when the cap is put on the mouth portion, the fourth convex portion is positioned in the open position by rotating the cap or the like. Here, when a plurality of first fitting portions (first convex portions) are formed on the outer peripheral surface of the mouth portion, the fourth convex portion is in an open position with respect to any one of the plurality of first convex portions. It should be located at. Thus, the cap when put in the mouth portion, even as a fourth convex portion is not located at the open position, towards the position of the fourth projecting portion of the first hand the first convex portion closest to direction Since the fourth convex portion may be moved, the fourth convex portion can be positioned at the open position without rotating the cap significantly. Further, even when a plurality of second fitting portions (fourth convex portions) are formed on the inner peripheral surface of the cap, any one of the plurality of fourth convex portions is in an open position with respect to the first convex portion. It should be located. Therefore, when the capped mouth portion, even as a fourth protrusion is not positioned at the open position, the fourth convex portion closest to the opposite direction to the first way direction from the first convex portion first Since it is sufficient to move the convex portion toward the one convex portion, the fourth convex portion can be positioned at the open position without rotating the cap significantly. The same effect can be obtained when a plurality of first fitting portions (first convex portions) and a plurality of second fitting portions (fourth convex portions) are formed. In this way, the amount of rotation of the cap when the cap is attached can be reduced.

Further, preferably, a plurality of first fitting portions are formed at equal intervals in the circumferential direction of the mouth portion, and a plurality of second fitting portions are formed around the cap so as to fit with each of the plurality of first fitting portions. It is formed at equal intervals in the direction. In this case, since each of the plurality of second fitting portions is fitted to each of the plurality of first fitting portions, a large fixing force can be obtained and the mouth of the container body is prevented from being removed more easily. It can be attached to the part.

More preferably, the second convex portion is formed in front of the first convex portion in the first direction and on the side opposite to the body portion in the axial direction of the mouth portion, and the third convex portion is the first. It is formed behind the first convex portion in the direction and on the body side of the first convex portion in the axial direction of the mouth portion. In this case, when the cap is attached to the mouth of the container body, the fourth convex portion and the fifth convex portion in the second fitting portion are between the second convex portion and the third convex portion in the first fitting portion. The second fitting portion can be compactly formed so that the and the sixth convex portion are located. Thereby, a plurality of second fitting portions can be easily formed even within a limited range of the inner peripheral surface of the cap.

Preferably, in the adjacent first fitting portions, the sixth convex portion can slide from the second convex portion of one first fitting portion to the third convex portion of the other first fitting portion. A seventh convex portion protruding outward in the radial direction of the mouth portion from the outer peripheral surface of the mouth portion between the second convex portion of one first fitting portion and the third convex portion of the other first fitting portion. Is formed. As described above, when mounting the container body on the mouth portion with the cap removed, it is first necessary to cover the mouth portion with the cap and position the fourth convex portion in the open position. When the cap is put on the mouth, the 4th convex part is not located in the open position and the 6th convex part comes into contact with the 7th convex part. The convex portion slides along the seventh convex portion to the third convex portion adjacent in the first direction, and the sixth convex portion slides along the third convex portion. When the sixth convex portion slides along the third convex portion, the fourth convex portion eventually reaches the open position. Further, when the cap is put on the mouth portion, the fourth convex portion is not located at the open position, and the sixth convex portion comes into contact with the second convex portion of the adjacent first fitting portion on the side opposite to the first direction. The same applies to the case where the cap is rotated in the first direction from that position, and the sixth convex portion slides along the second convex portion to the seventh convex portion adjacent to the first convex portion in the first direction. Then, the sixth convex portion slides along the seventh convex portion and the third convex portion adjacent to each other in the first direction, and the fourth convex portion eventually reaches the open position. In this way, even if the fourth convex portion is not located in the open position when the cap is put on, the fourth convex portion can be easily positioned in the open position simply by rotating the cap. This facilitates the operation of the cap.

Further, preferably, the seventh convex portion connects the second convex portion of one first fitting portion and the third convex portion of the other first fitting portion. In this case, the sixth convex portion can be slid more stably, and the operation of the cap becomes easier.

More preferably, in the axial direction of the mouth portion, the ascending gradient from the body side of the first convex portion to the side opposite to the body portion is ascending from the side opposite to the body portion of the first convex portion to the body portion side. It is formed on a steeper slope than the slope. In this case, it is easier for the first convex portion to push up the fourth convex portion when the fourth convex portion moves from the open position to the closed position than when the fourth convex portion moves from the closed position to the open position. Easy to get over the first convex part. This makes it easier to attach the cap to the mouth of the container body, and after attachment, the cap can be fixed so as not to shift in the axial direction of the mouth.

Preferably, the upward slope of the third convex portion in the direction opposite to the first direction is formed more gently than the upward slope of the first convex portion in the axial direction of the mouth portion from the body side to the side opposite to the body portion. The fourth convex portion is formed in the vicinity of the sixth convex portion. In this case, in the state where the fourth convex portion is in the closed position, the cap is opposed to the first direction rather than pushing up the fourth convex portion by the first convex portion by pulling the cap in the axial direction of the mouth portion of the container body. By rotating in the direction, it becomes easier to push up the sixth convex portion by the third convex portion. Here, when the cap is rotated in the direction opposite to the first direction from the state where the fourth convex portion is in the closed position, the sixth convex portion is pushed up by the third convex portion, and the sixth convex portion is further pushed up by the third convex portion. The fourth convex portion formed in the vicinity of is moved outward in the radial direction of the mouth portion. As a result, the fourth convex portion can easily get over the first convex portion. Therefore, the cap can be fixed so as not to be displaced in the axial direction of the mouth portion, and when it is desired to remove the cap, the cap can be easily removed by rotating the cap in the direction opposite to the first direction.

Further, preferably, the thickness of the cap in the radial direction of the cap is such that the second fitting portion is not formed between the adjacent second fitting portions, rather than the portion where the second fitting portion is formed. Is set to be smaller. When the fourth convex portion moves between the open position and the closed position, the fourth convex portion moves outward in the radial direction of the mouth portion of the container body in order to get over the first convex portion. Therefore, at this time, the portion of the cap where the second fitting portion (fourth convex portion) is formed bulges outward in the radial direction of the mouth portion. On the contrary, the portion of the cap where the second fitting portion is not formed between the adjacent second fitting portions is deformed so as to be pulled inward in the radial direction of the mouth portion. Here, since the thickness of the portion between the adjacent second fitting portions where the second fitting portion is not formed is formed smaller than the thickness of the portion where the second fitting portion is formed, the thickness is adjacent. It is easily deformed between the matching second fitting portions. As a result, the portion of the cap where the second fitting portion (fourth convex portion) is formed tends to bulge outward in the radial direction of the mouth portion, and the cap can be operated with a smaller force.

More preferably, when the cap is attached to the mouth portion, the upward slope from the side opposite to the body portion of the fourth convex portion to the body portion side in the axial direction of the mouth portion is the body portion of the fourth convex portion. It is formed so that the slope is steeper than the upward slope from the side to the side opposite to the body. In this case, it is easier for the first convex portion to push up the fourth convex portion when the fourth convex portion moves from the open position to the closed position than when the fourth convex portion moves from the closed position to the open position. Easy to get over the first convex part. This makes it easier to attach the cap to the mouth of the container body, and after attachment, the cap can be fixed so as not to shift in the axial direction of the mouth.

Preferably, when the cap is attached to the mouth, the ascending slope of the sixth convex portion in the first direction is from the side opposite to the body portion of the fourth convex portion in the axial direction of the mouth portion to the body portion side. The fourth convex portion is formed in the vicinity of the sixth convex portion. In this case, in the state where the fourth convex portion is in the closed position, the cap is opposed to the first direction rather than pushing up the fourth convex portion by the first convex portion by pulling the cap in the axial direction of the mouth portion of the container body. By rotating in the direction, it becomes easier to push up the sixth convex portion by the third convex portion. Here, when the cap is rotated in the direction opposite to the first direction from the state where the fourth convex portion is in the closed position, the sixth convex portion is pushed up by the third convex portion, and the sixth convex portion is further pushed up by the third convex portion. The fourth convex portion formed in the vicinity of is moved outward in the radial direction of the mouth portion. As a result, the fourth convex portion can easily get over the first convex portion. Therefore, the cap can be fixed so as not to be displaced in the axial direction of the mouth portion, and when it is desired to remove the cap, the cap can be easily removed by rotating the cap in the direction opposite to the first direction.

Further, preferably, when the cap is attached to the mouth portion, the second fitting portion has a portion extending in the first direction and a portion extending so that the first direction side approaches the body portion so as to have a substantially V shape. In addition, the fourth convex portion, the fifth convex portion, and the sixth convex portion are integrally formed. In this case, the strength of the second fitting portion can be increased. Therefore, the cap can be securely fixed to the mouth of the container body.

More preferably, the fourth convex portion, the fifth convex portion, and the sixth convex portion are arranged so that when the cap is attached to the mouth portion, the second fitting portion has a linear shape extending in the circumferential direction of the mouth portion. Are integrally formed. In this case, the strength of the second fitting portion can be increased and the second fitting portion can be easily formed. Therefore, the cap can be securely fixed to the mouth of the container body, and the manufacturing cost of the cap can be reduced.

Preferably, the second convex portion at the rear end portion of the second convex portion in the first direction is inclined so as to have an upward slope toward the first direction and to be located on the first direction side as it approaches the body portion. It has 3 sliding surfaces. In this case, when the cap is placed on the mouth of the container body and rotated in the first direction, even if the fifth convex portion comes into contact with the second convex portion (third sliding surface), the cap is kept in the first direction. The fifth convex portion can be slid along the second convex portion (third sliding surface), and the cap can be easily moved to the body side. This makes the cap easier to install.

The second fitting portions 42a to 42d are set to have the same shape and the same dimensions as each other, and are formed at equal intervals (in this embodiment, 90 degree intervals) in the circumferential direction of the cap 14. The second fitting portions 42a to 42d are each formed in a substantially V shape extending in a bifurcated direction in the direction opposite to the second direction M1 in the circumferential direction of the cap 14. The second fitting portion 42a has a fourth convex portion 44a projecting inward in the radial direction of the cap 14 so as to correspond to the first convex portion 22a, and a diameter of the cap 14 corresponding to the second convex portion 24a. It has a fifth convex portion 46a projecting inward in the direction and a sixth convex portion 48a projecting inward in the radial direction of the cap 14 so as to correspond to the third convex portion 26a. The fourth convex portion 44a, the fifth convex portion 46a, and the sixth convex portion 48a are integrally formed.

With reference to FIGS. 7 to 9, the fourth convex portion 44a is formed in a linear shape extending in the circumferential direction of the cap 14 slightly from the center of the axial end of the cap 14 (the sixth convex portion described later). The boundary with the portion 48a is shown by a chain double-dashed line in FIGS. 7 and 8). Further, the fourth convex portion 44a has a seventh sliding surface 50a extending in the circumferential direction of the cap 14 on the other end side of the cap 14 in the fourth convex portion 44a and a cap on one end side of the cap 14 in the fourth convex portion 44a. It has an eighth sliding surface 52a extending in the circumferential direction of 14. Here, one end of the cap 14 indicates an open end in the axial direction of the cap 14, and the other end of the cap 14 indicates a closed end of the cap 14 in the axial direction. The seventh sliding surface 50a is formed so as to have an upward slope from the other end side to the one end side of the cap 14. The eighth sliding surface 52a is formed so as to have an upward slope from one end side to the other end side of the cap 14. The ascending slope of the seventh sliding surface 50a is formed so as to be steeper than the ascending slope of the eighth sliding surface 52a.

The fifth convex portion 46a extends from the front end portion of the fourth convex portion 44a in the second direction M1 toward the other end side of the cap 14 as it advances in the direction opposite to the second direction M1. Further, the fifth convex portion 46a includes a ninth sliding surface 54a extending so that the second direction M1 side approaches one end side of the cap 14 on the other end side of the cap 14 in the fifth convex portion 46a, and the fifth convex portion 46a. On one end side of the cap 14, the second direction M1 side has a tenth sliding surface 56a extending so as to approach one end side of the cap 14. The ninth sliding surface 54a is formed so as to have an upward slope from the other end side to the one end side of the cap 14. The tenth sliding surface 56a is formed so as to have an upward slope from one end side to the other end side of the cap 14. The ascending slope of the tenth sliding surface 56a is formed so as to be steeper than the ascending slope of the ninth sliding surface 54a.

The sixth convex portion 48a extends rearward from the rear end portion of the fourth convex portion 44a in the second direction M1. Further, in the second direction M1, the sixth convex portion 48a has the eleventh sliding surface 58a extending rearward from the rear end portion of the seventh sliding surface 50a and the rear end portion of the eighth sliding surface 52a rearward. It has a twelfth sliding surface 60a extending and a thirteenth sliding surface 62a formed at the rear end of the sixth convex portion 48a. The eleventh sliding surface 58a is formed so as to have an upward slope from the other end side to the one end side of the cap 14. The twelfth sliding surface 60a is formed so as to have an upward slope from one end side to the other end side of the cap 14. The thirteenth sliding surface 62a is formed so as to have an uphill slope in the second direction M1. Further, the ascending slope of the 13th sliding surface 62a is formed more gently than the ascending slope of the 7th sliding surface 50a and the 11th sliding surface 58a.

When such a cap 14 is attached to the mouth portion 18, the fourth convex portion 44a is formed in a linear shape extending in the same direction as the first convex portion 22a in the circumferential direction of the mouth portion 18. The fifth convex portion 46a has a portion (9th sliding surface 54a) extending in substantially the same direction as the second convex portion 24a (fourth sliding surface 34a) so that the first direction D1 side approaches the body portion 16. Further, in the axial direction of the mouth portion 18, the ascending slope of the seventh sliding surface 50a is formed to be steeper than the ascending slope of the eighth sliding surface 52a. The ascending slope of the thirteenth sliding surface 62a in the first direction D1 is formed more gently than the ascending slope of the seventh sliding surface 50a in the axial direction of the mouth portion 18. The second fitting portion 42a includes a portion extending in the first direction D1 (a portion formed by the fourth convex portion 44a and the sixth convex portion 48a) and a portion extending so that the first direction D1 side approaches the body portion 16. It is formed so as to have a substantially V shape having (fifth convex portion 46a).

As described above, the second fitting portions 42b to 42d are each set to have the same shape and dimensions as the second fitting portion 42a, and in the above description of the second fitting portion 42a, the end of the code of each portion "a". Can be easily understood by replacing "" with "b" to "d", and thus the description of the second fitting portions 42b to 42d will be omitted. It should be noted that each part of the second fitting part 42b to 42d is shown by replacing the end "a" of the code of each corresponding part of the second fitting part 42a with "b" to "d" as necessary. There is.

A method of attaching and detaching the cap 14 to and from the mouth portion 18 will be described with reference to FIGS. 10 to 16. In FIGS. 11 to 14, in order to avoid complicating the drawings, the outer shape of the cap 14 is shown by a chain line, and the second fitting portions 42a to 42d are shown by broken lines.

First, referring to FIG. 10, when the cap 14 is attached to the mouth portion 18, the cap 14 and the container body 12 are arranged so as to be offset in the axial direction of the mouth portion 18. At this time, one end (opening side) of the cap 14 is directed toward the mouth portion 18.

With reference to FIG. 11, the cap 14 is moved toward the mouth portion 18 and the cap 14 is put on the mouth portion 18. At this time, the sixth convex portion 48a (12th sliding surface 60a side) comes into contact with the 7th convex portion 38 (sixth sliding surface 40 side). When the cap 14 is put on the mouth portion 18, the sixth convex portion 48a (12th sliding surface 60a side) may come into contact with the second convex portion 24b (third sliding surface 32b side). In the seventh convex portion 38 (sixth sliding surface 40), the sixth convex portion 48a is from the second convex portion 24b (third sliding surface 32b side) to the third convex portion 26a (fifth sliding surface 36a side). When the cap 14 is rotated in the first direction D1, the sixth convex portion 48a (12th sliding surface 60a side) becomes the second convex portion 24b (third slide). The second fitting portion 42a can be moved to the position shown in FIG. 11 by sliding along the moving surface 32b side) and the seventh convex portion 38 (sixth sliding surface 40 side). Here, since the outer peripheral surface of the cap 14 is formed so as to have a substantially regular icositetragon, it is possible to prevent the hand from slipping when the cap 14 is rotated, and the cap 14 can be operated satisfactorily.

When the cap 14 is rotated in the first direction D1 with reference to FIG. 12, the sixth convex portion 48a (12th sliding surface 60a side) is along the third convex portion 26a (fifth sliding surface 36a side). Sliding. Then, the fifth convex portion 46a (the ninth sliding surface 54a side) comes into contact with the second convex portion 24a (the fourth sliding surface 34a side), and the rotation of the cap 14 stops. By stopping the rotation of the cap 14 in this way, it becomes easy to grasp the position of the second fitting portion 42a, and the cap 14 can be operated satisfactorily.

With reference to FIG. 13, the cap 14 is further rotated in the first direction D1 or pushed toward the body portion 16.

When the cap 14 is further rotated in the first direction D1, the fifth convex portion 46a (the ninth sliding surface 54a side) slides along the second convex portion 24a (the fourth sliding surface 34a side). Here, the second convex portion 24a (fourth sliding surface 34a) and the fifth convex portion 46a (9th sliding surface 54a) extend so that the first direction D1 side approaches the body portion 16. Therefore, the fifth convex portion 46a moves toward the body portion 16 while moving in the first direction D1. As a result, the cap 14 moves toward the body portion 16 while rotating in the first direction D1. Then, when the fourth convex portion 44a (the eighth sliding surface 52a side) comes into contact with the first convex portion 22a (the first sliding surface 28a side), the rotation of the cap 14 stops. In this way, the state in which the fourth convex portion 44a is located on the side of the first convex portion 22a opposite to the body portion 16 (the side of the first sliding surface 28a) is defined as the open position (see FIG. 15).

On the other hand, when the cap 14 is pushed toward the body portion 16, the sixth convex portion 48a (12th sliding surface 60a side) slides along the third convex portion 26a (fifth sliding surface 36a side). Here, the third convex portion 26a (fifth sliding surface 36a) extends so that the first direction D1 side approaches the body portion 16. Therefore, the sixth convex portion 48a moves in the first direction D1 while moving toward the body portion 16. As a result, the cap 14 rotates in the first direction D1 while moving toward the body portion 16. Then, when the fourth convex portion 44a (the eighth sliding surface 52a side) comes into contact with the first convex portion 22a (the first sliding surface 28a side), the movement of the cap 14 stops. In this way, even if the cap 14 is pushed toward the body portion 16, the fourth convex portion 44a can be positioned in the open position in the same manner as when the cap 14 is rotated in the first direction D1 (see FIG. 15). ..

With reference to FIGS. 13 and 14, the cap 14 is further rotated in the first direction D1 or further pushed toward the body portion 16.

When the fourth convex portion 44a is in the open position, the fifth convex portion 46a is larger than the front end portion of the second convex portion 24a in the first direction D1 (the boundary with the seventh convex portion 38a shown in FIGS. 2 and 3). Located behind. Therefore, when the cap 14 is further rotated in the first direction D1, the fifth convex portion 46a (the ninth sliding surface 54a side) slides along the second convex portion 24a (the fourth sliding surface 34a side). Then, it moves to the body 16 side while moving in the first direction D1. Along with this, the fourth convex portion 44a also moves to the body portion 16 side while moving in the first direction D1. At this time, the fourth convex portion 44a (8th sliding surface 52a side) is gradually pushed outward along the first convex portion 22a (first sliding surface 28a side) in the radial direction of the mouth portion 18. .. As a result, the cap 14 bulges outward in the radial direction of the mouth portion 18 in the vicinity where the fourth convex portion 44a is formed. Then, the fourth convex portion 44a gets over the first convex portion 22a, and this time, the fourth convex portion 44a (7th sliding surface 50a side) is along the first convex portion 22a (second sliding surface 30a side). It returns inward in the radial direction of the mouth portion 18. In this way, the state in which the fourth convex portion 44a is located on the body portion 16 side (second sliding surface 30a side) of the first convex portion 22a is defined as the closed position (see FIG. 16). In this way, when the fourth convex portion 44a is moved from the open position to the closed position, the fourth convex portion 44a may be moved to the body portion 16 side by the amount of movement P1 in the axial direction of the mouth portion 18. Here, if the second sliding surface 30a and the seventh sliding surface 50a are set to have steep slopes, the fourth convex portion 44a (7th sliding surface 50a side) becomes the first convex portion 22a (second sliding surface). It can quickly return inward in the radial direction of the mouth portion 18 along the moving surface 30a side), and the fourth convex portion 44a can be positioned in the closed position with a click feeling. Therefore, since it can be easily grasped that the cap 14 is closed, it is possible to prevent the cap 14 from being closed too much, and even when the cap 14 is pulled in the axial direction of the mouth portion 18, the fourth convex portion 44a becomes the first convex portion 22a. It is possible to securely fix the cap 14 so that the cap 14 does not come off over the above. In the state where the fourth convex portion 44a is in the closed position, the cap 14 can rotate slightly in the circumferential direction of the mouth portion 18.

On the other hand, when the cap 14 is further pushed toward the body portion 16 while the fourth convex portion 44a is in the open position, the sixth convex portion 48a (12th sliding surface 60a side) becomes the third convex portion 26a (fifth slide). Sliding along the moving surface 36a side), the cap 14 moves in the first direction D1 while moving toward the body portion 16. Then, similarly to the case where the cap 14 is rotated in the first direction D1, the fourth convex portion 44a gets over the first convex portion 22a and moves to the closed position, and the cap 14 is attached to the mouth portion 18 ( (See FIG. 16).

When the cap 14 is removed from the mouth portion 18, the cap 14 is rotated in the direction opposite to the first direction D1. When the cap 14 is in the closed position, the sixth convex portion 48a is in front of the rear end portion of the third convex portion 26a in the first direction D1 (the boundary with the seventh convex portion 38a shown in FIGS. 2 and 3). To position. Therefore, when the cap 14 is rotated in the direction opposite to the first direction D1, the sixth convex portion 48a (13th sliding surface 62a side) is along the third convex portion 26a (fifth sliding surface 36a side). Sliding. Here, the third convex portion 26a (fifth sliding surface 36a) extends so that the first direction D1 side approaches the body portion 16. Further, the third convex portion 26a (fifth sliding surface 36a) has an upward slope in the direction opposite to the first direction D1. Therefore, the sixth convex portion 48a moves in the direction opposite to the first direction D1, moves to the side opposite to the body portion 16, and is pushed outward in the radial direction of the mouth portion 18. Along with this, the fourth convex portion 44a (7th sliding surface 50a side) moves outward in the radial direction of the mouth portion 18 along the first convex portion 22a (second sliding surface 30a side). I will go. Then, after the fourth convex portion 44a gets over the first convex portion 22a, the fourth convex portion 44a (8th sliding surface 52a side) is along the first convex portion 22a (second sliding surface 28a side). It returns inward in the radial direction of the mouth portion 18. Along with this, the sixth convex portion 48a also moves in the direction opposite to the first direction D1, moves to the side opposite to the body portion 16, and returns inward in the radial direction of the mouth portion 18. In this way, the fourth convex portion 44a is moved to the open position (see FIGS. 13 and 15). Then, when the cap 14 is further rotated in the direction opposite to the first direction D1, the cap 14 can be removed from the mouth portion 18.

In the above description, the case where the second fitting portion 42a is fitted with the first fitting portion 20a has been described, but similarly, the second fitting portion 42b has the first fitting portion 20b and the second fitting portion 20b. The joint portion 42c is fitted with the first fitting portion 20c, and the second fitting portion 42d is fitted with the first fitting portion 20d.

According to such a container 10, when the cap 14 is rotated in the first direction D1 to move the fourth convex portion 44a from the open position to the closed position (when the cap 14 is attached to the mouth portion 18 of the container body 12). ), The fourth convex portion 44a is moved toward the body portion 16 by sliding the fifth convex portion 46a along the second convex portion 24a. At this time, the larger the amount of rotation of the cap 14, the larger the amount of movement of the fourth convex portion 44a in the axial direction of the mouth portion 18 toward the body portion 16. Here, the first convex portion 22a is formed in a straight line extending in the circumferential direction of the mouth portion 18, and the fourth convex portion 44a is formed in a straight line extending in the same direction as the first convex portion 22a. Therefore, the dimensions of the first convex portion 22a and the dimensions of the fourth convex portion 44a can be reduced in the axial direction of the mouth portion 18. Therefore, in the axial direction of the mouth portion 18, the fourth convex portion 44a is required to move from the open position toward the body 16 side, get over the first convex portion 22a, and move to the closed position. The amount of movement P1 can be reduced. As a result, the amount of rotation of the cap 14 required for the fourth convex portion 44a to move from the open position to the closed position can be reduced. Further, the cap 14 can be attached to the mouth 18 simply by pushing the cap 14 as in the overcap type.

When the cap 14 is rotated in the direction opposite to the first direction D1 to move the fourth convex portion 44a from the closed position to the open position (when the cap 14 is removed from the mouth portion 18 of the container body 12), the sixth By sliding the convex portion 48a along the third convex portion 26a, the fourth convex portion 44a is moved to the side opposite to the body portion 16. At this time, the larger the amount of rotation of the cap 14, the larger the amount of movement of the fourth convex portion 44a in the axial direction of the mouth portion 18 to the side opposite to the body portion 16. Here, as described above, the first convex portion 22a is formed so as to extend linearly in the circumferential direction of the mouth portion 18, and the fourth convex portion 44a is formed so as to extend linearly in the same direction as the first convex portion 22a. Will be done. Therefore, the dimensions of the first convex portion 22a and the dimensions of the fourth convex portion 44a can be reduced in the axial direction of the mouth portion 18. Therefore, in the axial direction of the mouth portion 18, the fourth convex portion 44a moves from the closed position toward the side opposite to the body portion 16 and moves over the first convex portion 22a to the open position. The amount of movement P1 required for this can be reduced. As a result, the amount of rotation of the cap 14 required for the fourth convex portion 44a to move from the closed position to the open position can be reduced.

In this way, the amount of operation of the cap 14 when attaching / detaching the cap 14 to / from the container body 12 can be reduced, and the cap 14 can be easily attached / detached to / from the container body 12.

When attaching the cap 14 to the mouth portion 18 of the container body 12 from the state where the cap 14 is removed, first, the cap 14 is put on the mouth portion 18 and the fourth convex portions 44a to 44d are placed on the body portion 16 of the first convex portions 22a to 22d. It is necessary to position it on the opposite side (open position). If the fourth convex portions 44a to 44d are not located in the open position when the cap 14 is put on the mouth portion 18, the fourth convex portions 44a to 44d are set to the open position by rotating the cap 14 or the like. Position it. Here, since the plurality of first fitting portions 20a to 20d (first convex portions 22a to 22d) are formed on the outer peripheral surface of the mouth portion 18, any one of the plurality of first convex portions 22a to 22d The fourth convex portion 44a (44b to 44d) may be located at the open position. Therefore, when the cap 14 is put on the mouth portion 18, even if the fourth convex portion 44a (44b to 44d) is not located in the open position, the fourth convex portion 44a (44b to 44d) is positioned from the position of the fourth convex portion 44a (44b to 44d). Since the fourth convex portion 44a (44b to 44d) may be moved toward the first convex portion 22a to 22d closest to the one direction D1, the fourth convex portion 44a to 44a without rotating the cap 14 significantly. The 44d can be positioned in the open position. Further, since the plurality of second fitting portions 42a to 42d (fourth convex portions 44a to 44d) are formed on the inner peripheral surface of the cap 14, any one of the plurality of fourth convex portions 44a to 44d is the first. It may be located in the open position with respect to one convex portion 22a (22b to 22d). Therefore, when the cap 14 is put on the mouth portion 18, even if the fourth convex portions 44a to 44d are not located in the open position, the first convex portions 22a (22b to 22d) are opposite to the first direction D1. Since the fourth convex portions 44a to 44d closest to the direction may be moved toward the first convex portions 22a (22b to 22d), the fourth convex portions 44a to 44d can be moved without significantly rotating the cap 14. It can be positioned in the open position. In this way, the amount of rotation of the cap 14 when the cap 14 is attached can be reduced.

Since each of the plurality of second fitting portions 42a to 42d is fitted to each of the plurality of first fitting portions 20a to 20d, a large fixing force can be obtained and the cap 14 is made more difficult to come off. It can be attached to the mouth 18 of the container body 12.

When the cap 14 is attached to the mouth portion 18 of the container body 12, the second convex portion 24a (24b to 24d) and the third convex portion 26a (26b to 26d) in the first fitting portion 20a (20b to 20d) The fourth convex portion 44a (44b to 44d), the fifth convex portion 46a (46b to 46d), and the sixth convex portion 48a (48b to 48d) in the second fitting portion 42a (42b to 42d) are formed between the two. The second fitting portion 42a (42b to 42d) can be compactly formed so as to be located. Thereby, a plurality of second fitting portions 42a to 42d can be easily formed even within a limited range of the inner peripheral surface of the cap 14.

As described above, when mounting the cap 14 on the mouth 18 of the container body 12 with the cap 14 removed, it is first necessary to cover the cap 14 on the mouth 18 and position the fourth convex portion 44a in the open position. .. When the cap 14 is put on the mouth portion 18, if the fourth convex portion 44a is not located in the open position and the sixth convex portion 48a comes into contact with the seventh convex portion 38, the cap 14 is moved from that position in the first direction D1. When rotated to, the sixth convex portion 48a slides along the seventh convex portion 38 to the third convex portion 26a adjacent to the first direction D1, and the sixth convex portion 48a is further along the third convex portion 26a. Sliding. When the sixth convex portion 48a slides along the third convex portion 26a, the fourth convex portion 44a eventually reaches the open position. Further, when the cap 14 is put on the mouth portion 18, the fourth convex portion 44a is not located at the open position, and the sixth convex portion 48a is adjacent to the first fitting portion 20b on the side opposite to the first direction D1. The same applies when the cap 14 comes into contact with the second convex portion 24b, and when the cap 14 is rotated in the first direction D1 from that position, the sixth convex portion 48a is adjacent to the first direction D1 along the second convex portion 24b. 7 Slide up to the convex portion 38. Then, the sixth convex portion 48a slides along the seventh convex portion 38 and the third convex portion 26a adjacent to the first direction D1, and the fourth convex portion 44a eventually reaches the open position. In this way, even if the fourth convex portion 44a is not located in the open position when the cap 14 is put on, the fourth convex portion 44a can be easily positioned in the open position simply by rotating the cap 14. it can. This facilitates the operation of the cap 14.

Since the seventh convex portion 38 connects the second convex portion 24b of one first fitting portion 20b and the third convex portion 26a of the other first fitting portion 20a, the sixth convex portion 38 is more stable. The portion 48a can be slid, and the operation of the cap 14 becomes easier.

It is easier for the first convex portion 22a to push up the fourth convex portion 44a when the fourth convex portion 44a moves from the open position to the closed position than when the fourth convex portion 44a moves from the closed position to the open position, and the fourth convex portion 44a Is easy to get over the first convex portion 22a. As a result, the cap 14 can be easily attached to the mouth portion 18 of the container body 12, and the cap 14 can be fixed so as not to be displaced in the axial direction of the mouth portion 18 after attachment.

In the state where the fourth convex portion 44a is in the closed position, the cap 14 is first pushed up by the first convex portion 22a by pulling the cap 14 in the axial direction of the mouth portion 18 of the container body 12. By rotating in the direction opposite to the direction D1, it becomes easier to push up the sixth convex portion 48a by the third convex portion 26a. Here, when the cap 14 is rotated in the direction opposite to the first direction D1 from the state where the fourth convex portion 44a is in the closed position, the sixth convex portion 48a is pushed up by the third convex portion 26a, and the sixth convex portion 48a is further pushed up accordingly. , The fourth convex portion 44 formed in the vicinity of the sixth convex portion 48a moves outward in the radial direction of the mouth portion 18. As a result, the fourth convex portion 44a can easily get over the first convex portion 22a. Therefore, the cap 14 can be fixed so as not to be displaced in the axial direction of the mouth portion 18, and when the cap 14 is desired to be removed, the cap 14 can be easily removed by rotating the cap 14 in the direction opposite to the first direction D1.

When the fourth convex portion 44a moves between the open position and the closed position, the fourth convex portions 44a to 44d are outside the radial direction of the mouth portion 18 of the container body 12 in order to get over the first convex portions 22a to 22d. Move towards. Therefore, at this time, the portion of the cap 14 where the second fitting portions 42a to 42d (fourth convex portions 44a to 44d) are formed bulges outward in the radial direction of the mouth portion 18. On the contrary, the portion of the cap 14 where the second fitting portions 42a to 42d are not formed between the adjacent second fitting portions 42a to 42d is deformed so as to be pulled inward in the radial direction of the mouth portion 18. .. Here, the thickness R1 of the portion between the adjacent second fitting portions 42a to 42d where the second fitting portions 42a to 42d are not formed is the portion where the second fitting portions 42a to 42d are formed. Since it is formed to be smaller than the thickness S1, the space between the adjacent second fitting portions 42a to 42d is easily deformed. As a result, the portion of the cap 14 where the second fitting portions 42a to 42d (fourth convex portions 44a to 44d) are formed tends to bulge outward in the radial direction of the mouth portion 18, and the cap is capped with a smaller force. 14 can be operated.

When the cap 14 is attached to the mouth portion 18, the second fitting portion 42a has a substantially V-shape having a portion extending in the first direction D1 and a portion extending so that the first direction D1 side approaches the body portion 16.

The 14th sliding surface 154a is formed so as to have an upward slope from one end side to the other end side of the cap 104. The fifteenth sliding surface 156a has an uphill slope in the second direction M2.

When such a cap 104 is attached to the mouth portion 108, the fourth convex portion 136a is formed in a linear shape extending in the same direction as the first convex portion 112a in the circumferential direction of the mouth portion 108.

As described above, the second fitting portions 134b to 134d are set to have the same shape and dimensions as the second fitting portion 134a, respectively, and in the above description of the second fitting portion 134a, the end of the reference numeral "a" of each portion is set. Can be easily understood by replacing "" with "b" to "d", and thus the description of the second fitting portions 134b to 134d will be omitted. It should be noted that each part of the second fitting part 134b to 134d is shown by replacing the end "a" of the code of each corresponding part of the second fitting part 134a with "b" to "d" as necessary. There is.

The annular convex portion 131 is formed coaxially with the outer peripheral surface of the cap 104.

The annular convex portion 133 is formed coaxially with the outer peripheral surface of the cap 104 in the radial direction of the cap 104 with respect to the annular convex portion 131. The annular convex portion 133 projects so as to slightly expand outward in the radial direction of the cap 104 toward the tip end portion of the annular convex portion 133.

The annular convex portion 135 is formed coaxially with the outer peripheral surface of the cap 104 in the radial direction of the cap 104 with respect to the annular convex portion 133. The annular convex portion 135 projects so as to slightly expand outward in the radial direction of the cap 104 toward the tip end portion of the annular convex portion 135, and a groove extending in the circumferential direction of the cap 104 is formed on the outer peripheral surface of the annular convex portion 135. Will be done.

A method of attaching and detaching the cap 104 to and from the mouth 108 will be described with reference to FIGS. 25 to 31. In FIGS. 26 to 29, the outer shape of the cap 104 is shown by a chain line and the second fitting portions 134a to 134d are shown by broken lines in order to avoid complicating the drawings.

First, referring to FIG. 25, when the cap 104 is attached to the mouth portion 108, the cap 104 and the container body 102 are arranged so as to be offset in the axial direction of the mouth portion 108. At this time, one end (opening side) of the cap 104 is directed toward the mouth 108.

With reference to FIG. 26, the cap 104 is moved toward the mouth 108, and the cap 104 is put on the mouth 108. At this time, the sixth convex portion 140a (14th sliding surface 154a side) comes into contact with the third convex portion 116a (sixth sliding surface 128a side). When the cap 104 is put on the mouth portion 108, the sixth convex portion 140a (14th sliding surface 154a side) becomes the second convex portion 114b (fourth sliding surface 124b side) or the seventh convex portion 130 (the fourth sliding surface 124b side). 7 It may come into contact with the sliding surface 132 side). In the seventh convex portion 130 (seventh sliding surface 132), the sixth convex portion 140a is from the second convex portion 114b (fourth sliding surface 124b side) to the third convex portion 116a (sixth sliding surface 128a side). When the cap 104 is rotated in the first direction D2, the sixth convex portion 140a (14th sliding surface 154a side) becomes the second convex portion 114b (fourth slide). The second fitting portion 134a can be moved to the position shown in FIG. 26 by sliding along the moving surface 124b side) and the seventh convex portion 130 (seventh sliding surface 132 side). Here, since the outer peripheral surface of the cap 104 is formed so as to have a substantially regular icositetragon, it is possible to prevent the hand from slipping when the cap 104 is rotated, and the cap 104 can be operated satisfactorily.

When the cap 104 is further rotated in the first direction D2 with reference to FIG. 27, the sixth convex portion 140a (14th sliding surface 154a side) becomes the third convex portion 116a (sixth sliding surface 128a side). Slide along. Then, the fifth convex portion 138a (10th sliding surface 146a side) comes into contact with the second convex portion 114a (fifth sliding surface 126a side), and the rotation of the cap 104 stops. By stopping the rotation of the cap 104 in this way, it becomes easy to grasp the position of the second fitting portion 134a, and the cap 104 can be operated satisfactorily. Further, the third sliding surface 122a is inclined so as to be located on the D2 side in the first direction as it approaches the body portion 106. Therefore, even if the fifth convex portion 138a (12th sliding surface 150a side) comes into contact with the second convex portion 114a (third sliding surface 122a side) when the cap 104 is rotated in the first direction D2. When the cap 104 is rotated in the first direction D2 as it is, the fifth convex portion 138a (12th sliding surface 150a side) slides along the second convex portion 114a (third sliding surface 122a side). The second fitting portion 134a can be easily moved to the position shown in FIG. 27. In this way, the cap 104 can be easily moved to the body portion 106 side, which facilitates the attachment of the cap 104.

With reference to FIG. 28, the cap 104 is further rotated in the first direction D2 or pushed toward the body portion 106.

When the cap 104 is further rotated in the first direction D2, the fifth convex portion 138a (10th sliding surface 146a side) slides along the second convex portion 114a (fifth sliding surface 126a side). Here, the second convex portion 114a (fifth sliding surface 126a side) and the fifth convex portion 138a (tenth sliding surface 146a) extend so that the first direction D2 side approaches the body portion 106 side. Therefore, the fifth convex portion 138a moves toward the body portion 106 while moving in the first direction D2. Further, when the fifth convex portion 138a (10th sliding surface 146a) slides along the second convex portion 114a (fifth sliding surface 126a side), the fifth convex portion 138a and the second convex portion 114a Since the contact surface with the user becomes large, it is possible to prevent the fifth convex portion 138a from being damaged. When the fifth convex portion 138a moves toward the body portion 106 while moving in the first direction D2, the cap 104 moves toward the body portion 106 while rotating in the first direction D2. Then, when the fourth convex portion 136a (the ninth sliding surface 144a side) comes into contact with the first convex portion 112a (the first sliding surface 118a side), the rotation of the cap 104 stops. The state in which the fourth convex portion 136a is located on the side of the first convex portion 112a opposite to the body portion 106 (the side of the first sliding surface 118a) is defined as the open position (see FIG. 30). When the fourth convex portion 136a is in the open position, the tip portion of the annular convex portion 133 presses the inner peripheral surface of the opening of the mouth portion 108, so that the sealing property can be maintained even in this state.

On the other hand, when the cap 104 is pushed toward the body portion 106, the sixth convex portion 140a (14th sliding surface 154a side) slides along the third convex portion 116a (sixth sliding surface 128a side). Here, the third convex portion 116a (sixth sliding surface 128a) extends so that the first direction D2 side approaches the body portion 106. Therefore, the sixth convex portion 140a moves in the first direction D2 while moving toward the body portion 106 side. As a result, the cap 104 rotates in the first direction D2 while moving toward the body portion 106. Then, when the fourth convex portion 136a (the ninth sliding surface 144a side) comes into contact with the first convex portion 112a (the first sliding surface 118a side), the movement of the cap 104 stops. In this way, even if the cap 104 is pushed toward the body portion 106, the fourth convex portion 136a can be positioned in the open position in the same manner as when the cap 104 is rotated in the first direction D2 (see FIG. 30). ..

With reference to FIG. 29, the cap 104 is further rotated in the first direction D2 or further pushed toward the body portion 106.

When the fourth convex portion 136a is in the open position, the fifth convex portion 138a is located behind the front end portion of the second convex portion 114a in the first direction D2. Therefore, when the cap 104 is further rotated in the first direction D2, the fifth convex portion 138a (10th sliding surface 146a side) slides along the second convex portion 114a (fifth sliding surface 126a side). Then, it moves to the body 106 side while moving in the first direction D2. Along with this, the fourth convex portion 136a also moves to the body portion 106 side while moving in the first direction D2. At this time, the fourth convex portion 136a (9th sliding surface 144a side) is gradually pushed outward along the first convex portion 112a (first sliding surface 118a side) in the radial direction of the mouth portion 108. .. As a result, the cap 104 bulges outward in the radial direction of the mouth portion 108 in the vicinity where the fourth convex portion 136a is formed. Then, the fourth convex portion 136a gets over the first convex portion 112a, and this time, the fourth convex portion 136a (the eighth sliding surface 142a side) is along the first convex portion 112a (the second sliding surface 120a side). It returns inward in the radial direction of the mouth portion 108. In this way, the state in which the fourth convex portion 136a is located on the body portion 106 side (second sliding surface 120a side) of the first convex portion 112a is defined as the closed position (see FIG. 31). When the fourth convex portion 136a is in the closed position, the annular convex portion 131 is in close contact with the opening of the mouth portion 108, the annular convex portion 133 presses the inner peripheral surface of the opening of the mouth portion 108, and the cap 104. Is attached to the mouth 108. In this way, when the fourth convex portion 136a is moved from the open position to the closed position, the fourth convex portion 136a may be moved toward the body portion 106 by the amount of movement P2 in the axial direction of the mouth portion 108. Here, if the second sliding surface 120a and the eighth sliding surface 142a are set to have steep slopes, the fourth convex portion 136a (the eighth sliding surface 142a side) becomes the first convex portion 112a (second sliding surface). It can quickly return inward in the radial direction of the mouth portion 108 along the moving surface 120a side), and the fourth convex portion 136a can be positioned in the closed position with a click feeling. Therefore, since it can be easily grasped that the cap 104 is closed, it is possible to prevent the cap 104 from being closed too much, and even when the cap 104 is pulled in the axial direction of the mouth portion 108, the fourth convex portion 136a is the first convex portion 112a. It can be securely fixed so that the cap 104 does not come off over the above. In the state where the fourth convex portion 136a is in the closed position, the cap 104 can rotate slightly in the circumferential direction of the mouth portion 108.

On the other hand, when the cap 104 is further pushed toward the body portion 106 while the fourth convex portion 136a is in the open position, the sixth convex portion 140a (14th sliding surface 154a side) becomes the third convex portion 116a (sixth slide). It slides along the moving surface 128a side) and moves in the first direction D2 while moving toward the body 106 side. Then, similarly to the case where the cap 104 is rotated in the first direction D2, the fourth convex portion 136a gets over the first convex portion 112a and moves to the closed position, and the cap 104 is attached to the mouth portion 108 ( (See FIG. 31).

When the cap 104 is removed from the mouth 108, the cap 104 is rotated in the direction opposite to the first direction D2. When the cap 108 is in the closed position, the sixth convex portion 140a is located in front of the rear end portion (see FIG. 18) of the third convex portion 116a in the first direction D2. Therefore, when the cap 104 is rotated in the direction opposite to the first direction D2, the sixth convex portion 140a (15th sliding surface 156a side) is along the third convex portion 116a (sixth sliding surface 128a side). Sliding. Here, the third convex portion 116a (sixth sliding surface 128a) extends so that the first direction D2 side approaches the body portion 106. Further, the third convex portion 116a (sixth sliding surface 128a) has an upward gradient in the direction opposite to the first direction D2. Therefore, the sixth convex portion 140a moves in the direction opposite to the first direction D2, moves to the side opposite to the body portion 106, and is pushed outward in the radial direction of the mouth portion 108. Along with this, the fourth convex portion 136a (8th sliding surface 142a side) moves outward in the radial direction of the mouth portion 108 along the first convex portion 112a (second sliding surface 120a side). I will go. Then, after the fourth convex portion 136a gets over the first convex portion 112a, the fourth convex portion 136a (the ninth sliding surface 144a side) is along the first convex portion 112a (the first sliding surface 118a side). It returns inward in the radial direction of the mouth 108. Along with this, the sixth convex portion 140a also moves in the direction opposite to the first direction D2, moves to the side opposite to the body portion 106, and returns inward in the radial direction of the mouth portion 108. In this way, the fourth convex portion 136a is moved to the open position (see FIGS. 28 and 30). Then, when the cap 104 is further rotated in the direction opposite to the first direction D2, the cap 104 can be removed from the mouth portion 108.

In the above description, the case where the second fitting portion 134a is fitted with the first fitting portion 110a has been described, but similarly, the second fitting portion 134b has the first fitting portion 110b and the second fitting portion 110b. The joint portion 134c is fitted with the first fitting portion 110c, and the second fitting portion 134d is fitted with the first fitting portion 110d.

According to such a container 100, when the cap 104 is rotated in the first direction D2 to move the fourth convex portion 136a from the open position to the closed position (when the cap 104 is attached to the mouth portion 108 of the container main body 102). ), The fourth convex portion 136a is moved toward the body portion 106 by sliding the fifth convex portion 138a along the second convex portion 114a. At this time, the larger the amount of rotation of the cap 104, the larger the amount of movement of the fourth convex portion 136a in the axial direction of the mouth portion 108 toward the body portion 106. Here, the first convex portion 112a is formed in a straight line extending in the circumferential direction of the mouth portion 108, and the fourth convex portion 136a is formed in a straight line extending in the same direction as the first convex portion 112a. Therefore, the dimensions of the first convex portion 112a and the dimensions of the fourth convex portion 136a can be reduced in the axial direction of the mouth portion 108. Therefore, in the axial direction of the mouth portion 108, the fourth convex portion 136a is required to move from the open position toward the body 106 side, overcome the first convex portion 112a, and move to the closed position. The amount of movement P2 can be reduced. As a result, the amount of rotation of the cap 104 required for the fourth convex portion 136a to move from the open position to the closed position can be reduced. Further, the cap 104 can be attached to the mouth 108 by simply pushing the cap 104 as in the overcap type.

When the cap 104 is rotated in the direction opposite to the first direction D2 to move the fourth convex portion 136a from the closed position to the open position (when the cap 104 is removed from the mouth 108 of the container body 102), the sixth By sliding the convex portion 140a along the third convex portion 116a, the fourth convex portion 136a is moved to the side opposite to the body portion 106. At this time, the larger the amount of rotation of the cap 104, the larger the amount of movement of the fourth convex portion 136a in the axial direction of the mouth portion 108 to the side opposite to the body portion 106. Here, as described above, the first convex portion 112a is formed so as to extend linearly in the circumferential direction of the mouth portion 108, and the fourth convex portion 136a is formed so as to extend linearly in the same direction as the first convex portion 112a. Will be done. Therefore, the dimensions of the first convex portion 112a and the dimensions of the fourth convex portion 136a can be reduced in the axial direction of the mouth portion 108. Therefore, in the axial direction of the mouth portion 108, the fourth convex portion 136a moves from the closed position toward the side opposite to the body portion 106, gets over the first convex portion 112a, and moves to the open position. The amount of movement P2 required for this can be reduced. As a result, the amount of rotation of the cap 104 required for the fourth convex portion 136a to move from the closed position to the open position can be reduced.

In this way, the amount of operation of the cap 104 when attaching and detaching the cap 104 to and from the container body 102 can be reduced, and the cap 104 can be easily attached to and detached from the container body 102.

When attaching the cap 104 to the mouth 108 of the container body 102 from the state where the cap 104 is removed, first, the cap 104 is put on the mouth 108 and the fourth convex portions 136a to 136d are placed on the body portion 106 of the first convex portions 112a to 112d. It is necessary to position it on the opposite side (open position). If the fourth convex portions 136a to 136d are not located in the open position when the cap 104 is put on the mouth portion 108, the fourth convex portions 136a to 136d are set to the open position by rotating the cap 104 or the like. Position it. Here, since the plurality of first fitting portions 110a to 110d (first convex portions 112a to 112d) are formed on the outer peripheral surface of the mouth portion 108, any one of the plurality of first convex portions 112a to 112d. The fourth convex portion 136a (136b to 136d) may be located at the open position. Therefore, when the cap 104 is put on the mouth portion 108, even if the fourth convex portion 136a (136b to 136d) is not located in the open position, the fourth convex portion 136a (136b to 136d) is the first from the position of the fourth convex portion 136a (136b to 136d). Since the fourth convex portion 136a (136b to 136d) may be moved toward the first convex portion 112a to 112d closest to the one direction D2, the fourth convex portion 136a to 136a without rotating the cap 104 significantly. 136d can be positioned in the open position. Further, since the plurality of second fitting portions 134a to 134d (fourth convex portions 136a to 136d) are formed on the inner peripheral surface of the cap 104, any one of the plurality of fourth convex portions 136a to 136d is the first. It may be located in an open position with respect to one convex portion 112a (112b to 112d). Therefore, when the cap 104 is put on the mouth portion 108, even if the fourth convex portions 136a to 136d are not located in the open position, the first convex portions 112a (112b to 112d) are opposite to the first direction D2. Since the fourth convex portions 136a to 136d closest to the direction may be moved toward the first convex portions 112a (112b to 112d), the fourth convex portions 136a to 136d can be moved without significantly rotating the cap 104. It can be positioned in the open position. In this way, the amount of rotation of the cap 104 when the cap 104 is attached can be reduced.

Since each of the plurality of second fitting portions 134a to 134d is fitted to each of the plurality of first fitting portions 110a to 110d, a large fixing force can be obtained and the cap 104 is less likely to come off. It can be attached to the mouth 108 of the container body 102.

When the cap 104 is attached to the mouth 108 of the container body 102, the second convex portions 114a (114b to 114d) and the third convex portions 116a (116b to 116d) in the first fitting portion 110a (110b to 110d) The fourth convex portion 136a (136b to 136d), the fifth convex portion 138a (138b to 138d), and the sixth convex portion 140a (140b to 140d) in the second fitting portion 134a (134b to 134d) are formed between the two. The second fitting portions 134a (134b to 134d) can be compactly formed so as to be located. Thereby, a plurality of second fitting portions 134a to 134d can be easily formed even within a limited range of the inner peripheral surface of the cap 104.

As described above, when the cap 104 is attached to the mouth portion 108 of the container body 102 from the state where the cap 104 is removed, it is first necessary to cover the mouth portion 108 with the cap 104 and position the fourth convex portion 136a in the open position. .. When the cap 104 is put on the mouth portion 108, if the fourth convex portion 136a is not located in the open position and the sixth convex portion 140a comes into contact with the seventh convex portion 130, the cap is moved from that position to the first direction D2. When rotated, the sixth convex portion 140a slides along the seventh convex portion 130 to the third convex portion 116a adjacent to the first direction D2, and the sixth convex portion 140a further slides along the third convex portion 116a. Sliding. When the sixth convex portion 140a slides along the third convex portion 116a, the fourth convex portion 136a eventually reaches the open position. Further, when the cap 104 is put on the mouth portion 108, the fourth convex portion 136a is not located at the open position, and the sixth convex portion 140a is adjacent to the first fitting portion 110b on the side opposite to the first direction D2. The same applies to the case of contact with the second convex portion 114b of the above, and when the cap 104 is rotated in the first direction D2 from that position, the sixth convex portion 140a is adjacent to the first direction D2 along the second convex portion 114b. It slides to the seventh convex portion 130. Then, the sixth convex portion 140a slides along the seventh convex portion 130 and the third convex portion 116a adjacent to the first direction D2, and the fourth convex portion 136a eventually reaches the open position. In this way, even if the fourth convex portion 136a is not located in the open position when the cap 104 is put on, the fourth convex portion 136a can be easily positioned in the open position simply by rotating the cap 104. it can. This facilitates the operation of the cap 104.

Since the seventh convex portion 130 connects the second convex portion 114b of one first fitting portion 110b and the third convex portion 116a of the other first fitting portion 110a, the sixth convex portion 130 is more stable. The portion 140a can be slid, and the operation of the cap 104 becomes easier.

When the fourth convex portion 136a moves from the open position to the closed position, it is easier for the first convex portion 112a to push up the fourth convex portion 136a than when the fourth convex portion 136a moves from the closed position to the open position, and the fourth convex portion 136a Is easy to get over the first convex 112a. This makes it easier to attach the cap 104 to the mouth 108 of the container body 102, and after mounting, the cap 104 can be fixed so as not to be displaced in the axial direction of the mouth 108.

In the state where the fourth convex portion 136a is in the closed position, the cap 104 is first pushed up by the first convex portion 112a by pulling the cap 104 in the axial direction of the mouth portion 108 of the container body 102. By rotating in the direction opposite to the direction D2, it becomes easier to push up the sixth convex portion 140a by the third convex portion 116a. Here, when the cap 104 is rotated in the direction opposite to the first direction D2 from the state where the fourth convex portion 136a is in the closed position, the sixth convex portion 140a is pushed up by the third convex portion 116a, and the sixth convex portion 140a is further pushed up accordingly. , The fourth convex portion 136 formed in the vicinity of the sixth convex portion 140a moves outward in the radial direction of the mouth portion 108. As a result, the fourth convex portion 136a can easily get over the first convex portion 112a. Therefore, the cap 104 can be fixed so as not to be displaced in the axial direction of the mouth portion 108, and when the cap 104 is desired to be removed, the cap 104 can be easily removed by rotating the cap 104 in the direction opposite to the first direction D2.

When the fourth convex portion 136a moves between the open position and the closed position, the fourth convex portions 136a to 136d are outside the radial direction of the mouth portion 108 of the container body 102 in order to get over the first convex portions 112a to 112d. Move towards. Therefore, at this time, the portion of the cap 104 where the second fitting portions 134a to 134d (fourth convex portions 136a to 136d) are formed bulges outward in the radial direction of the mouth portion 108. On the contrary, the portion of the cap 104 where the second fitting portions 134a to 134d are not formed between the adjacent second fitting portions 134a to 134d is deformed so as to be pulled inward in the radial direction of the mouth portion 108. .. Here, the thickness R2 of the portion between the adjacent second fitting portions 134a to 134d where the second fitting portions 134a to 134d are not formed is the portion where the second fitting portions 134a to 134d are formed. Since it is formed smaller than the thickness S2, it is easily deformed between the adjacent second fitting portions 134a to 134d. As a result, the portion of the cap 104 where the second fitting portions 134a to 134d (fourth convex portions 136a to 136d) are formed tends to bulge outward in the radial direction of the mouth portion 108, and the cap is capped with a smaller force. 104 can be operated.

The fourth convex portion 136a, the fifth convex portion 138a, and the sixth convex so that the second fitting portion 134a extends in the circumferential direction of the mouth portion 108 when the cap 104 is attached to the mouth portion 108. The portion 140a is integrally formed. In this case, the strength of the second fitting portion 134a can be increased and the second fitting portion 134a can be easily formed. Therefore, the cap 104 can be securely fixed to the mouth 108 of the container body 102, and the manufacturing cost of the cap 104 can be reduced.
