<Mating condition between cap body and skirt>
The cap of the present invention can be used by fitting the cap main body (10) and the skirt (50) so as to be relatively rotatable about the cap axis. 9 to 14 show the state in which the cap body (10) and the skirt (50) are fitted together.

9 and 10 show a cap (100) in which the cap body (10) and the skirt (50) are fitted together, in which the lid (40) is prevented from swinging in the opening direction. . 9 is a side sectional view, and FIG. 10 is a front sectional view.

Referring to Figures 9 and 10, a cap body rotation recess (22) formed on the outer surface of the cap base suspension (26) and a skirt rotation protrusion (22) formed on the inner surface of the skirt suspension (56). It can be understood that the portion (52) is rotatably fitted around the cap axis.

In this state, the cap mouth (24) and the skirt opening (51) are integrally connected to the inside of the container.

In this state, the skirt engaging arm (53) further penetrates the skirt engaging arm through-hole (21) formed in the cap base flat portion (25) and protrudes inward from the lid suspension portion (46). The lid engaging claw (41) is engaged with the claw at the tip of the skirt engaging arm (53). This prevents the lid (40) from swinging in the opening direction.

12 and 13 show a cap (100) in which the cap body (10) and the skirt (50) are fitted together, in which the lid (40) can swing in the opening direction. 12 is a side sectional view, and FIG. 13 is a front sectional view. 12 and 13 correspond to the state shown in FIGS. 9 and 10, in which the skirt (50) is rotated about the cap axis by 90° while the cap body (10) remains fixed. .

12 and 13, the cap body rotation concave portion (22) on the outer surface of the cap base suspension portion (26) and the skirt rotation protrusion (52) on the inner surface of the skirt suspension portion (56) are As in the case of FIGS. 9 and 10, they are rotatably fitted and the cap opening (24) and the skirt opening (51) are integrally communicated with the inside of the container.

However, in this case, due to the relative rotation between the cap body (10) and the skirt (50), the position of the skirt engaging arm (53) deviates from the position where it can be engaged with the lid engaging claw (41). ing. Therefore, the skirt engaging arm (53) does not appear in the side sectional view of FIG. 12, but appears in the front sectional view of FIG. 13 where the lid portion engaging claw (41) does not exist. In this state, there is no element that prevents the lid (40) from swinging in the opening direction, so the lid can be opened.

(Number of cap body engaging portions and skirt engaging portions)
In the cap (100) shown in FIGS. 9, 10, 12 and 13, the cap body (10) has lid portion engaging claws (41) as cap body engaging portions, and the skirt (50) engages the skirt. It has a skirt engaging arm (53) as a joining portion, and the number of pairs of these cap body engaging portion and skirt engaging portion is one. However, the number of pairs of the cap body engaging portion and the skirt engaging portion may be one, or two or more. Preferably 1 to 4 pairs, more preferably 1 or 2 pairs.

(Snap cap engaging portion and snap skirt engaging portion)
Reference is now made to FIGS. 11 and 14. FIG. FIG. 11 shows a cap (100) in which the cap body (10) and the skirt (50) are fitted together, in which the lid portion (40) is prevented from swinging in the opening direction, as shown in FIG. It is an AA arrow view. FIG. 14 is an AA view of FIG. 12 showing a state in which the lid (40) can be swung in the opening direction. 11 and 14, the section of the cap base suspension (26) of the cap body (10) forming the inner circle and the skirt (50) forming the outer circle are shown respectively. of the skirt suspension (56) are visible.

The cap base suspension (26), which appears as an inner circle in FIG. A cap body recess (23) is formed in the gap between the two cap body recess forming protrusions (23a, 23b) in the set.

In FIG. 11, the skirt suspension (56), which appears as an outer circle, has skirt ridges (54) on two inner walls approximately every 180°.

The cap body recess (23) of the cap base suspension (26) functions as a snap cap engaging portion, and the skirt protrusion (54) of the skirt suspension (56) functions as a snap skirt engaging portion. . That is, when the skirt engaging arm (53) and the lid engaging claw (41) are engaged to restrict the rocking of the lid (40) in the opening direction, the cap body recess ( 23) and the skirt projection (54) are snapped together, thereby limiting the relative rotation of the skirt (50) and the cap body (10) about the cap axis. In FIG. 11, the skirt protrusions (54) of the skirt suspension (56) are located at two locations in the horizontal direction of the drawing, respectively, in the horizontal direction of the cap body recess (23) of the cap base suspension (26). are engaged (snap-engaged) with two of

In order for the skirt (50) to rotate from the state shown in FIG. 11, the skirt projection (54) needs to get over the cap main body recess forming projections (23a, 23b). Here, if the rotational force applied between the skirt (50) and the cap body (10) is small, the skirt projections (54) cannot get over the cap body recess formation projections (23a, 23b), resulting in snap engagement. cannot be removed. However, if the applied rotational force is large, the cap base suspension (26) or the skirt suspension (56), or both, will elastically deform and the skirt projections (54) will become two (a pair of) caps. Either of the body recess forming projections (23a, 23b) is overcome to disengage the snap engagement, allowing the skirt (50) to rotate relative to the cap body (10). As a result, the state shown in FIGS. 12 and 13, in which the lid portion (40) can swing in the opening direction, can be achieved, and the cap can be opened. When the cap is opened, the contents of the container can be removed through the cap mouth (24) and the skirt opening (51), which are integrally connected to the interior of the container.

The small rotational force applied between the skirt (50) and the cap body (10) includes, for example, rotational force that is accidentally applied due to vibration during transportation, rotational force that is applied when an infant tries to open the cap. A rotational force or the like is conceivable in the case of careless touching. The large rotational force is, for example, the rotational force when an adult holds the skirt (50) with one hand and turns the cap body (10) with the other hand with the intention of opening the cap.

Here, if one of the two projections forming the concave portion of the cap body is a projection so large that it cannot be overcome even by a large rotational force, the snap engaging portion of the cap of the present invention can also be used for rotational direction control. can be done.

In the cap (100) of FIG. 11, one of the two (a set of) cap body recess forming projections is the large cap body recess forming projection (23a), and the large cap body recess forming projection (23a) and the small cap body recess forming projection (23a) The formation order of the body recess forming projections (23b) is configured to be opposite to the order of formation of the other adjacent pairs on the outer wall of the cap base suspension portion (26). That is, when the inner circumference of FIG. 11 is viewed clockwise from the right set,
A set of large cap body recess forming protrusions (23a) and small cap body recess forming protrusions (23b) in order (right side of FIG. 11);
A set of small cap body recess forming protrusions (23b) and large cap body recess forming protrusions (23a) in that order (lower side of FIG. 11);
A set of large cap body recess forming protrusion (23a) and small cap body recess forming protrusion (23b) in order (left side of FIG. 11); and small cap body recess forming protrusion (23b) and large cap body recess forming protrusion (23a) (upper side of FIG. 11);
exist in the order of

By setting the arrangement order of the cap body recess forming projections as described above, the skirt (50) of the cap (100) can be rotated 90 degrees clockwise with respect to the cap body (10), but can be rotated in the opposite direction. Clockwise rotation is prevented.

FIG. 14 is a view taken along line AA in FIG. 12 showing a state in which the lid (40) can be swung in the opening direction. (26) remains fixed, while the skirt suspension (56), which appears as the outer circle, is rotated 90° clockwise. In FIG. 14, the skirt protrusions (54) of the skirt suspension section (56) are located at two locations in the vertical direction of the drawing, and are respectively located in the vertical direction of the cap body recesses (23) of the cap base suspension section (26). It snaps into two.

When a rotational force is applied between the skirt (50) and the cap body (10) in this state, the skirt projections (54) cannot get over the large cap body recess forming projections (23a). ) is prohibited from rotating clockwise with respect to the cap body (10). As a result, the skirt engagement arm (53) of the skirt (50) is prevented from rotating beyond the forming range of the skirt engagement arm through-hole (21) of the cap base (20). Damage to the arm (53), the skirt engagement arm through-hole (21), etc. can be prevented.

On the other hand, for counterclockwise rotation of the skirt (50), if the rotational force applied between the skirt (50) and the cap body (10) is small, the skirt protrusion (54) will form a small cap body recess. It cannot get over the protrusion (23b) and cannot rotate. However, if the applied rotational force is large, the skirt projection (54) will overcome the small cap body recess forming projection (23b), causing the skirt (50) to rotate counterclockwise with respect to the cap body (10). becomes possible. Therefore, in the cap (100) of this aspect, it is possible to prevent the skirt (50) and the cap body (10) from rotating relative to each other while the cap is being opened. The comfort of use is ensured when the container is opened.

In the cap of this embodiment, the skirt projection (54) contacts the adjacent large cap body recess forming projection (23a) in FIG. position can be rotated approximately 90° clockwise. This rotation angle can be arbitrarily adjusted by the number and arrangement of the skirt protrusions (54) and the cap body recesses (23). This rotation angle may be appropriately set according to, for example, the number of pairs of the skirt engaging portion and the cap body engaging portion, the angle of the arc of the skirt engaging arm through hole (21), and the like.

As described above, the cap main body concave portion (23) and the skirt convex portion (54) work together to prevent the skirt (50) and the cap main body (10) from rotating relative to each other in the closed state. functions to prevent unintentional opening; to allow easy opening when necessary.

The cap body concave portion (23) and the skirt convex portion (54) preferably further prevent the skirt (50) and the cap body (10) from rotating relative to each other when the cap is opened. It also functions to prevent excessive rotation of the skirt (50) and the cap body (10) to prevent breakage of the cap.

Even when the cap body (10) and the skirt (50) rotate relatively, the cap base (20) and the lid (40) do not rotate relatively, so the lid engagement arm cap base through hole ( 29) need not have an arcuate shape like the skirt engaging arm through hole (21) in the typical example. The lid engagement arm cap base through-hole (29) only needs to have a size and shape that allows the lid engagement arm (47) to pass therethrough and to be removed from the penetration state.

On the other hand, the lid portion engagement arm skirt through hole (58) formed in the skirt flat portion (55) of the skirt (50) is designed to allow the lid portion to rotate with the relative rotation of the cap body (10) and the skirt (50). It may have an arcuate shape at a predetermined angle to allow arcuate movement of the lid engaging arm (47) and prevent excessive rotation of the lid engaging arm (47). For the arcuate shape of the lid engaging arm (47), the above description of the skirt engaging arm (53) in the typical example applies as is or with appropriate modifications made by those skilled in the art. you can

Furthermore,
the skirt-engaging portion is a skirt-engaging arm extending from the skirt;
the cap body engaging portion is a lid portion engaging arm extending from the lid portion toward the skirt engaging arm;
The cap base has a lid engagement arm through hole for passing the lid engagement arm through to reach the skirt engagement arm,
Caps are also included in the invention.

FIG. 16 shows a side cross-sectional view of the cap of this embodiment when the cap main body and the skirt are fitted together and the cap is closed. FIG. 16 corresponds to FIG. 9 used to describe the above typical example.

In the cap (120) of FIG. 16, the cap body (10) has a lid engagement arm (47) extending downward in the drawing from the lower surface of the lid flat portion (45). One skirt (50) has a skirt engaging arm (53) extending from the skirt flat portion (55) toward the tip of the lid engaging arm (47). A lid engagement arm cap base through-hole (29) is formed in the cap base flat portion (25). The lid engaging arm (47) passes through a lid engaging arm cap base through hole (29) formed in the cap base flat surface (25), reaches the skirt engaging arm (53), and engages the lid. The claw at the tip of the part engaging arm (47) and the claw at the tip of the skirt engaging arm (53) are engaged. In the cap (120) of FIG. 16, such a mechanism prevents the lid (40) from swinging in the opening direction.

In the cap (120) of FIG. 16, similar to the cap (110) of FIG. 15, even when the cap body (10) and the skirt (50) rotate relatively ), the lid engaging arm cap base through-hole (29) need not have an arcuate shape like the skirt engaging arm through-hole (21) in the typical example, It suffices to have a size and shape that allows the lid engaging arm (47) to be penetrated and removed from the penetrated state.

(Another example of snap cap engaging portion and snap skirt engaging portion)
The cap of the present invention includes a snap cap that restricts relative rotation between the skirt and the cap body by snap engagement when the skirt engagement portion and the cap body engagement portion are engaged. An engagement portion and a snap skirt engagement portion are provided.

In the typical example described above, the snap cap-engaging portion is the cap body recess, the snap skirt-engaging portion is the skirt protrusion, and by relatively rotating the skirt and the cap body, the caps can be The configuration was such that the body concave portion and the skirt convex portion were arranged to engage or disengage the snap engagement.

However, the snap cap engaging portion and the snap skirt engaging portion may be a combination of a cap body projection and a skirt recess. The skirt recess may be formed in the gap between two skirt recess forming projections that are arranged in close proximity.

FIG. 17 shows a schematic cross-sectional view for explaining the configuration of the snap cap engaging portion and the snap skirt engaging portion in the cap of this embodiment. FIG. 17 corresponds to FIG. 11 used to describe the above typical example.

In the cross-sectional view of the cap (130) shown in FIG. 17, the skirt suspension (56), which appears as an outer circle, has two skirt recess-forming projections (60a, 60b) on the inner wall at approximately 90° intervals. has a set consisting of In each of these sets, a skirt recess (60) is formed between two skirt recess forming projections (60a, 60b).

Further in the cap (130) of FIG. 17, the cap base suspension (26), which appears as an inner circle, has cap body projections (28) on two inner walls approximately every 180°.

In FIG. 17, the cap body projections (28) of the cap base suspension (26) are located in two horizontal locations in the figure, and each of the skirt recesses (60) of the skirt suspension (56) is located horizontally. It snaps into two.

Whether or not the cap body projections (28) can get over the skirt recess formation projections (60a, 60b) depends on the magnitude of the rotational force applied between the skirt (50) and the cap body (10). If the rotational force applied between the skirt (50) and the cap body (10) is small, the cap body protrusion (28) will not be able to climb over the skirt recess forming protrusions (60a, 60b), thus releasing the snap engagement. Therefore, the relative rotation between the skirt (50) and the cap body (10) is restricted, and the unplugging prevention state is maintained. When the rotational force applied between the skirt (50) and the cap body (10) is large, the cap body protrusion (28) climbs over one of the skirt recess forming protrusions (60a, 60b) to disengage the snap engagement. and the skirt (50) can rotate relative to the cap body (10) to allow the cap to be opened.

Thus, the skirt recess (60) and the cap body projection (28) collectively act as a snap engagement to control the relative rotation of the skirt (50) and the cap body (10) by snap engagement. can function.

In the cap (130) of FIG. 17, one of the two skirt recess forming protrusions may be a protrusion so large that it cannot be overcome even by a large rotational force, so as to have a rotational direction control function.

In the cap (130) of FIG. 17, one of the two (a set of) skirt recess forming protrusions is a large skirt recess forming protrusion (60a), and the large skirt recess forming protrusion (60a) and the small skirt recess forming protrusion (60a) The formation order of (60b) is configured to be opposite to the formation order of the other adjacent pairs on the inner wall of the skirt suspension portion (56).

In the cap (130) of FIG. 17, the cap body protrusion (28) cannot get over the large skirt recess forming protrusion (60a). Therefore, the skirt (50) is prevented from rotating counterclockwise with respect to the cap body (10).
