Description

This invention relates to containers, and more particularly to containers with caps.

Containers with caps may be shipped by air. When a container is being airlifted, the pressure around the container drops. Under such a reduced pressure environment, the pressure inside the container increases, and there is a risk that the cap may come off. Therefore, Patent Document 1 proposes a container mouth portion 2 having an annular tightening flange 14 formed on the outer peripheral surface thereof, and a container lid 16 attached to the container mouth portion 2 . The annular clamping flange 14 has a downwardly radially outwardly sloping upper surface 14a and a downwardly radially inwardly sloping lower surface 14b. A locking projection 28 is formed on the inner peripheral surface of the container lid 16 . The locking projection 28 climbs over the annular tightening flange 14 and engages with the lower surface 14b of the annular tightening flange 14, so that the container lid 16 is stably held on the container opening 2, thereby avoiding the above-mentioned adverse effects during air transportation. can be suppressed.

Japanese Utility Model Laid-Open No. 57-151237

In Patent Document 1, the container lid 16 can be removed from the container opening 2 by moving the locking projection 28 over the lower surface 14b of the annular tightening flange 14 toward the upper surface 14a of the annular tightening flange 14. can. However, in Patent Document 1, the inclination of the lower surface 14b of the annular tightening flange 14 is formed in the same manner over the entire circumference of the container mouth portion 2 . Therefore, when removing the container lid 16 from the container mouth portion 2, it is not easy for the locking projection 28 to get over the lower surface 14b of the annular tightening flange 14, and the container lid 16 can be easily removed from the container mouth portion 2. is not.

SUMMARY OF THE INVENTION Therefore, it is a primary object of the present invention to provide a container which can increase the fixing force of the cap and can easily remove the cap.

In order to achieve the above object, a container body having a body and a mouth extending cylindrically from the body, and a cap attached to and detached from the mouth are provided. The cap has a first portion and a second portion that protrude radially outward from the cap, and the cap has a third portion that protrudes radially inward from the inner peripheral surface facing the outer peripheral surface of the mouth. The first part locks the third part so that the cap does not come off from the mouth when the third part is positioned in the first closed position facing the first part, and also holds the mouth. The second part is provided in front of the second part in the first direction of the direction, and the second part moves over the second part from the state in which the third part is positioned in the second closed position facing the second part to close the cap to the mouth. A container is provided that is formed to slope less gently than the first portion toward the side opposite the body so that it can be removed from the container.

According to the present invention, the mouth has a first portion and a second portion that protrude outward in the radial direction of the mouth on the outer peripheral surface of the mouth. The second portion is formed so as to have a gentler upward slope than the first portion toward the side opposite to the trunk portion. In other words, the first portion is formed to be steeper than the second portion toward the side opposite the barrel. Therefore, when the cap is attached to the mouth, the first portion, which is formed to be steeper than the second portion, engages the third portion, thereby preventing the cap from coming off the mouth. . On the other hand, when the cap is removed from the mouth portion, the cap is removed by applying a force to the cap that allows the third portion to climb over the second portion, which is formed to have a gentler upward slope than the first portion. It can be easily removed from the mouth. In this way, the slope of the first portion that locks the third portion so that the cap does not come off from the mouth differs from the slope of the second portion that the third portion climbs over to remove the cap from the mouth. The fixing force of the cap can be increased and the cap can be easily removed.

Preferably, the mouth further has a fourth portion that protrudes radially outward from the mouth from a side opposite to the barrel from the first portion on the outer peripheral surface of the mouth, and the fourth portion comprises: The third part has a gentler upward slope than the first part toward the trunk side so that the third part can move from the first open position facing the fourth part to the first closed position over the fourth part. is formed as In this case, when the third portion moves over the fourth portion and moves to the first closed position, a click feeling is generated. Therefore, it is possible to know that the cap has been attached to the mouth by a click feeling, so that the cap can be attached more securely to the mouth.

Moreover, preferably, the mouth has a diameter such that the outer peripheral surface of the mouth is located at least in front of the third portion in the first direction when the third portion is located at the first open position. It further has a fifth portion projecting outward in the direction, and the fifth portion is formed such that the first direction side approaches the barrel. In this case, by rotating the cap in the first direction, the third portion moves in the first direction along the fifth portion to approach the barrel without getting over the fifth portion. Therefore, by rotating the cap, the third portion can be moved over the fourth portion to the first closed position, so that the cap can be easily attached to the mouth.

More preferably, the mouth further has a sixth portion projecting radially outward of the mouth from the side opposite to the barrel from the second portion on the outer peripheral surface of the mouth, and the sixth portion is , the third portion can move from the second closed position to the second open position facing the sixth portion by overcoming the second portion, and the third portion can move over the sixth portion from the second open position to the second closed position. It is formed so that it cannot be moved to a position. In this case, the sixth part locks the third part so that the third part is not in the second closed position when the cap is attached to the mouth. Accordingly, the third portion is prevented from moving through the second open position, through the second closed position, and into the first closed position to attach the cap to the mouth, and the third portion moves from the first open position. The cap can be attached to the mouth by moving to the first closed position. As a result, it is possible to know that the cap has been attached to the mouth by a click feeling, so that the cap can be attached more securely to the mouth.

Preferably, the sixth portion extends from the rear of the second portion toward the fourth portion in the first direction. In this case, even if the third portion is not positioned at the first open position and contacts the sixth portion when the cap is placed over the mouth, the third portion can be moved to the first position by rotating the cap in the first direction. It can be moved towards 4 parts. Therefore, since the third portion can be easily moved to the first open position when the cap is attached to the mouth, the cap can be easily attached to the mouth.

Also preferably, the height of the second portion is lower than the height of the first portion in the radial direction of the mouth. In this case, the height of the first portion is higher than the height of the second portion. Therefore, when the cap is attached to the mouth, the first portion, which is higher than the second portion, engages the third portion, so that the cap can be attached so as not to come off from the mouth. On the other hand, when removing the cap from the mouth, the cap can be easily removed from the mouth by the third part getting over the second part, which is lower in height than the first part. In this way, the fixing force of the cap can be further increased, and the cap can be removed more easily.

More preferably, the mouth portion has a diameter such that the outer peripheral surface of the mouth portion is located at least behind the third portion in the first direction when the third portion is located in the second closed position. It further has a seventh portion projecting outward in the direction, and the seventh portion is formed such that the first direction side approaches the trunk. In this case, by rotating the cap in a direction opposite to the first direction, the third portion moves along the seventh portion in a direction opposite to the first direction without overriding the seventh portion. Move away from the department. Therefore, by rotating the cap, the third portion can be moved over the second portion to the second open position, so that the cap can be easily removed from the mouth.

According to the present invention, it is possible to obtain a container in which the fixing force of the cap can be increased and the cap can be easily removed.

Here, the axial direction of the cap 14 is the direction indicated by arrow I in FIGS. 2, 9 and 11, the radial direction of the cap 14 is the direction indicated by the arrow J in FIGS. The circumferential direction is the direction indicated by arrow K in FIGS. The cap 14 has a plurality (four in this embodiment) of sixth projections 50a to 50d formed on the inner peripheral surface so as to be fittable with the fitting portions 20a to 20d, respectively.

The sixth protrusions 50a to 50d are set to have the same shape and size, and are formed at equal intervals (in this embodiment, at intervals of 90 degrees) in the circumferential direction of the cap 14. As shown in FIG. Each of the sixth protrusions 50a to 50d linearly extends in the circumferential direction of the cap 14 in the vicinity of one end of the cap 14 in the axial direction. Here, the one end of the cap 14 means the open end of the cap 14 in the axial direction, and the other end of the cap 14 means the closed end of the cap 14 in the axial direction.

In this embodiment, the upward slopes of the 13th surface 52a, the 14th surface 54a and the 15th surface 56a are set to approximately 90 degrees.

As described above, the sixth protrusions 50b to 50d are each set to have the same shape and dimensions as the sixth protrusion 50a. The description of the sixth projections 50b to 50d will be omitted since they can be easily understood by reading them as "b" to "d". It should be noted that each portion of the sixth convex portions 50b to 50d is illustrated by replacing the suffix "a" of the corresponding portions of the sixth convex portion 50a with "b" to "d" as necessary.

In this embodiment, the first surfaces 32a to 32d respectively correspond to the first portion, the fourth surfaces 36a to 36d respectively correspond to the second portion, and the sixth convex portions 50a to 50d respectively correspond to the third portion. , the second surfaces 33a to 33d correspond to the fourth portion, and the ninth surfaces 44a to 44d respectively correspond to the fifth portion. Also, the sixth surface 38a and the twelfth surface 48a correspond to the sixth portion. Similarly, the sixth surface 38b and the twelfth surface 48b, the sixth surface 38c and the twelfth surface 48c, and the sixth surface 38d and the twelfth surface 48d respectively correspond to the sixth portion. Each of the eleventh surfaces 46a to 46d corresponds to the seventh portion.

A method of attaching and detaching the cap 14 to the opening 18 will be described with reference to FIGS. 12 to 18. FIG. 12 to 18, the illustration of the sixth projections 50b to 50d is omitted in order to avoid complication of the drawings. Also, the outer shape of the cap 14 is indicated by a dashed line, and the sixth convex portion 50a is indicated by a broken line.

Referring to FIG. 12, cap 14 is first placed over opening 18 . At this time, when the sixth convex portion 50a contacts the sixth surface 38a, since the sixth surface 38a is formed on the side opposite to the body portion 16 with respect to the fourth surface 36a, the sixth convex portion 50a contacts the sixth surface 38a. 2 It is locked to the sixth surface 38a so as not to be positioned at the closed position (described later). In this embodiment, the upward slope of the sixth surface 38a and the upward slope of the fourteenth surface 54a in the cross section FF are set to approximately 90 degrees, so that the sixth surface 38a can more reliably engage the sixth convex portion 50a. can be locked. When the cap 14 is put on the mouth portion 18, the sixth convex portion 50a may come into contact with the twelfth surface 48a. The twelfth surface 48a is connected to the sixth surface 38a. Therefore, when the sixth convex portion 50a contacts the twelfth surface 48a, rotating the cap 14 in the first direction D moves the sixth convex portion 50a along the twelfth surface 48a and the sixth surface 38a. , the sixth convex portion 50a can be moved to the position shown in FIG.

12 and 14, when the cap 14 is further rotated in the first direction D from the state of FIG. 12, the sixth projection 50a moves along the sixth surface 38a. And the 6th convex part 50a contacts the 2nd surface 33a and the 9th surface 44a before long. When the sixth convex portion 50a contacts the second surface 33a and the ninth surface 44a, the sixth convex portion 50a faces the second surface 33a in the axial direction of the mouth portion 18. As shown in FIG. Thus, the position where the sixth convex portion 50a faces the second surface 33a is defined as the first open position (see FIGS. 14 and 19). Further, referring to FIGS. 12 and 13, the eighth surface 42a inclines so as to be located on the first direction D side as it approaches the body portion 16. As shown in FIG. Therefore, as shown in FIG. 13, even if the sixth convex portion 50a contacts the eighth surface 42a when the cap 14 is rotated in the first direction D from the state shown in FIG. When rotated in the direction D, the sixth convex portion 50a moves toward the trunk portion 16 side while moving in the first direction D along the eighth surface 42a. As a result, the sixth convex portion 50a can be easily moved to the first open position, and attachment of the cap 14 is facilitated.

14 and 15, cap 14 is further rotated in first direction D from the state of FIG. The ninth surface 44a is positioned at least in front of the sixth convex portion 50a in the first direction D when the sixth convex portion 50a is positioned at the first open position. That is, the ninth surface 44a has a portion positioned at least in front of the sixth convex portion 50a in the first direction D when the sixth convex portion 50a is positioned at the first open position. Therefore, when the cap 14 is further rotated in the first direction D from the state of FIG. 14, the sixth convex portion 50a moves toward the trunk portion 16 side while moving in the first direction D along the ninth surface 44a. Accordingly, the sixth convex portion 50a is gradually pushed up radially outward of the mouth portion 18 along the second surface 33a. As a result, the cap 14 bulges outward in the radial direction of the mouth portion 18 in the vicinity of where the sixth convex portion 50a is formed. Then, the sixth convex portion 50a returns radially inward of the mouth portion 18 after passing over the second surface 33a and the third surface 34a. When the sixth convex portion 50a overcomes the second surface 33a and the third surface 34a and returns radially inward of the mouth portion 18, the sixth convex portion 50a comes into contact with the tenth surface 45a, and the cap 14 is closed. It is locked to the tenth surface 45a so as not to rotate in the first direction D, and faces the first surface 32a in the axial direction of the mouth portion 18. As shown in FIG. Thus, the position where the sixth convex portion 50a faces the first surface 32a is defined as the first closed position (see FIGS. 15 and 20). When the sixth projecting portion 50a is positioned at the first closed position, the first surface 32a engages the sixth projecting portion 50a from the side opposite to the trunk portion 16 from the sixth projecting portion 50a. Therefore, when the sixth convex portion 50a is positioned at the first closed position, the cap 14 is attached to the mouth portion 18 so as not to come off the mouth portion 18 . In this embodiment, the upward slope of the first surface 32a and the fifteenth surface 56a is set to approximately 90 degrees, so the first surface 32a is positioned so that the cap 14 does not come off the mouth portion 18. It can be locked more securely. The cap 14 can also be attached to the mouth portion 18 by pushing the cap 14 toward the body portion 16 when the sixth convex portion 50a is positioned at the first open position.

In this embodiment, when the cap 14 is attached to the mouth portion 18, the axial direction of the cap 14 and the axial direction of the mouth portion 18, the radial direction of the cap 14 and the radial direction of the mouth portion 18, and the circumferential direction of the cap 14. The circumferential direction of the mouth portion 18, and the first direction D and the second direction L are aligned with each other.

15 and 16, when removing the cap 14 from the mouth portion 18, the cap 14 is first rotated in the direction opposite to the first direction D. As shown in FIG. Then, the sixth convex portion 50a comes into contact with the eleventh surface 46a. When the sixth convex portion 50a contacts the eleventh surface 46a, the sixth convex portion 50a faces the fourth surface 36a in the axial direction of the mouth portion 18. As shown in FIG. Thus, the position where the sixth convex portion 50a faces the fourth surface 36a is defined as the second closed position (see FIGS. 16 and 21).

16 to 18, the cap 14 is further rotated in the direction opposite to the first direction D from the state shown in FIG. The eleventh surface 46a is formed to be positioned at least rearward in the first direction D of the sixth protrusion 50a when the sixth protrusion 50a is positioned at the second closed position. That is, the eleventh surface 46a has at least a portion located behind the sixth convex portion 50a in the first direction D when the sixth convex portion 50a is positioned at the second closed position. Therefore, when the cap 14 is further rotated in the direction opposite to the first direction D from the state of FIG. It moves to the side opposite to the body part 16. - 特許庁Accordingly, the sixth convex portion 50a is gradually pushed up along the fourth surface 36a radially outward of the mouth portion 18 (see FIGS. 17 and 22). As a result, the cap 14 bulges outward in the radial direction of the mouth portion 18 in the vicinity of where the sixth convex portion 50a is formed. Then, the sixth convex portion 50a returns radially inward of the mouth portion 18 after passing over the fourth surface 36a and the seventh surface 40a. When the sixth convex portion 50a moves over the fourth surface 36a and the seventh surface 40a and returns radially inward of the mouth portion 18, the sixth convex portion 50a moves toward the sixth surface 38a in the axial direction of the mouth portion 18. Oppose. Thus, the position where the sixth convex portion 50a faces the sixth surface 38a is defined as the second open position (see FIGS. 18 and 23). In addition, since the thirteenth surface 52a is formed so that the first direction D side approaches the trunk portion 16, the sixth convex portion 50a can be smoothly moved along the eleventh surface 46a. Further, the eleventh surface 46a is formed to have a steeper slope than the fourth surface 36a, and the upward slope of the thirteenth surface 52a is set to be approximately 90 degrees. It can move more reliably along the 11th surface 46a without getting over the 11th surface 46a. The cap 14 can be removed from the mouth portion 18 by moving the cap 14 to the opposite side of the body portion 16 while the sixth convex portion 50a is in the second open position.

In the above description, the case where the sixth convex portion 50a fits with the fitting portion 20a has been described. 20c and the sixth convex portion 50d are fitted with the fitting portion 20d. Also, the sixth convex portion 50a can be fitted with any one of the fitting portions 20b to 20d. do.

According to the container 10 as described above, the mouth portion 18 has the first surface 32a and the fourth surface 36a that protrude outward in the radial direction of the mouth portion 18 on the outer peripheral surface of the mouth portion 18 . The fourth surface 36a is formed to have a gentler upward slope than the first surface 32a toward the side opposite to the body portion 16. As shown in FIG. In other words, the first surface 32a is formed so as to be steeper than the fourth surface 36a toward the side opposite to the body portion 16 . Therefore, when the cap 14 is attached to the mouth portion 18, the first surface 32a, which is formed to be steeper than the fourth surface 36a, engages the sixth convex portion 50a, thereby attaching the cap 14 to the mouth portion. It can be installed so as not to come off from 18. On the other hand, when the cap 14 is removed from the mouth portion 18, a sufficient force is applied so that the sixth convex portion 50a can get over the fourth surface 36a which is formed to have a gentler upward slope than the first surface 32a. Cap 14 can be easily removed from mouth 18 by rotating cap 14 . In this way, the inclination of the first surface 32a that engages the sixth projection 50a to prevent the cap 14 from coming off the opening 18 and the inclination of the first surface 32a that engages the sixth projection 50a in order to remove the cap 14 from the mouth 18 are the same. Since the inclination is different from that of the four surfaces 36a, the fixing force of the cap 14 can be increased and the cap 14 can be easily removed.

Further, when removing the cap 14 from the mouth portion 18, the cap 14 is rotated by applying a force to the extent that the sixth convex portion 50a can get over the fourth surface 36a, and the cap 14 is moved to the opposite side of the body portion 16. need to move. In other words, the cap 14 does not come off from the mouth portion 18 unless a sufficient force is applied so that the sixth convex portion 50a can get over the fourth surface 36a. Therefore, for example, even when the container 10 is knocked down while the sixth convex portion 50a is positioned at the second closed position, it is possible to prevent the cap 14 from coming off from the mouth portion 18 .

A click feeling is generated when the sixth protrusion 50a moves over the second surface 33a and the third surface 34a to move to the first closed position. Therefore, since it is possible to know that the cap 14 has been attached to the mouth portion 18 by a click feeling, the cap 14 can be attached more securely to the mouth portion 18 .

By rotating the cap 14 in the first direction D, the sixth convex portion 50a approaches the body portion 16 while moving in the first direction D along the ninth surface 44a without getting over the ninth surface 44a. to move. Therefore, by rotating the cap 14, the sixth convex portion 50a can move over the second surface 33a and the third surface 34a to the first closed position, so that the cap 14 can be easily attached to the mouth portion 18. FIG.

The sixth surface 38a locks the sixth convex portion 50a so that the sixth convex portion 50a is not positioned at the second closed position when the cap 14 is attached to the mouth portion 18 . Therefore, the sixth convex portion 50a is prevented from moving through the second open position, through the second closed position, and into the first closed position to prevent the cap 14 from being attached to the mouth portion 18. The cap 14 can be attached to the mouth 18 by moving from the first open position to the first closed position. As a result, it is possible to know that the cap 14 has been attached to the mouth portion 18 by a click feeling, so that the cap 14 can be attached more securely to the mouth portion 18.例文帳に追加

Even if the sixth convex portion 50a contacts the sixth surface 38a or the twelfth surface 48a when the cap 14 is placed over the mouth portion 18, the sixth convex portion 50a can be removed by rotating the cap 14 in the first direction D. 50a can be moved toward the second surface 33a. Therefore, when the cap 14 is attached to the mouth portion 18, the sixth protrusion 50a can be easily moved to the first open position, so that the cap 14 can be attached to the mouth portion 18 easily.

In the radial direction of the mouth portion 18, the height T1 of the fourth surface 36a and the height of the portion of the seventh surface 40a connecting the fourth surface 36a and the sixth surface 38a are higher than the height T2 of the first surface 32a. is also low. In other words, the height T2 of the first surface 32a is higher than the height T1 of the fourth surface 36a and the height of the portion of the seventh surface 40a that connects the fourth surface 36a and the sixth surface 38a. Therefore, when the cap 14 is attached to the mouth portion 18, the first surface 32a of the fourth surface 36a and the seventh surface 40a, which is higher than the portion connecting the fourth surface 36a and the sixth surface 38a, is the sixth surface. By locking the convex portion 50a, the cap 14 can be attached so as not to come off from the mouth portion 18. As shown in FIG. On the other hand, when the cap 14 is removed from the mouth portion 18, the portion connecting the fourth surface 36a and the sixth surface 38a of the fourth surface 36a and the seventh surface 40a which are lower than the first surface 32a is the sixth convex. The cap 14 can be easily removed from the mouth portion 18 by the portion 50a getting over. Thus, the cap 14 can be more easily removed while the fixing force of the cap 14 can be further increased.

By rotating the cap 14 in the direction opposite to the first direction D, the sixth protrusion 50a rotates in the opposite direction to the first direction D along the eleventh surface 46a without getting over the eleventh surface 46a. It moves away from the trunk 16 while moving. Therefore, by rotating the cap 14, the sixth convex portion 50a can move over the fourth surface 36a and the seventh surface 40a to the second open position, so that the cap 14 can be easily removed from the mouth portion 18. .

In the above-described embodiment, the case where the plurality of fitting portions 20a to 20d are formed so as to be shifted by 90 degrees in the circumferential direction of the mouth portion 18 and formed continuously has been described, but the present invention is not limited to this. . The plurality of fitting portions need not be formed so as to be shifted by 90 degrees. Also, at least one fitting portion may be formed.

In the above-described embodiment, a case has been described in which the plurality of sixth protrusions 50a to 50d are formed at regular intervals in the circumferential direction of the cap 14, but the present invention is not limited to this. At least one 6-protrusion should be formed.
