In the configuration of Patent Document 1, there is room for improvement in terms of ease of operation for pinching the knob to break the weakened portion.

SUMMARY OF THE INVENTION The present invention has been made in consideration of such circumstances, and an object of the present invention is to facilitate the operation of pinching the grip portion to break the weakened portion.

In order to solve the above problems, a container according to an aspect of the present invention includes a bottomed cylindrical main body member for containing contents, and a topped cylindrical lid member for closing the mouth of the main body member. , wherein the peripheral wall of the lid member is formed with a knob projecting radially outward from the peripheral wall and a weakened portion extending in the circumferential direction, the knob extending radially outward from the peripheral wall. a projecting piece projecting in a first direction in the circumferential direction from a radially outer end of the supporting portion; and an operation protrusion projecting in a second direction opposite to the first direction, and the center line of the protrusion and the center line of the operation protrusion are misaligned in a radial direction in a plan view. there is

According to the above aspect, since the radial positions of the center line of the projecting piece and the center line of the operating protrusion are deviated, the thickness of the connecting portion between the operating protrusion and the support portion of the knob is increased. can be used to increase rigidity. As a result, when the operating protrusion is pinched and pulled radially outward, the force can be easily transmitted to the supporting portion, and the weakened portion can be broken more easily.

Here, the peripheral wall may be formed with an eaves portion that protrudes radially outward and covers at least a portion of the knob portion from above.

Since the knob protrudes radially outward from the peripheral wall of the lid member, for example, when the container is distributed or stored, an external force may be applied unexpectedly, such as when the knob hits another article, and the weakened portion may break. be. Therefore, by covering the knob portion from above with the eaves portion as described above, it is possible to prevent the weakened portion from unexpectedly breaking due to another article or the like coming into contact with the knob portion.

Further, the peripheral wall is formed with a convex portion that protrudes radially inward, and the knob portion is deformed or displaced radially outward by contacting the main body member with the convex portion. good too.

According to this configuration, it is possible to make the knob easier to grip by increasing the radially outward protrusion of the knob without increasing the radial dimension of the knob. In addition, since the amount of protrusion of the knob portion can be reduced before the lid member is attached to the main body member, the lid members can be smoothly aligned by an automatic parts feeder (parts feeder), for example, and the assembly machine can be used. Thus, the lid member can be smoothly supplied to the next step.

Further, the knob portion may be formed with an inclined surface connecting a radially outer end surface of the projecting piece and a radially outer end surface of the operating projection.

In this case, the slant surface more reliably increases the thickness of the connecting portion between the operating protrusion and the support portion, thereby increasing the rigidity of the knob portion. In addition, when the operation protrusion is pinched and pulled radially outward, deformation such as bending of the operation protrusion starting from the support portion is suppressed, and force can be more reliably transmitted to the support portion.

According to the above aspect of the present invention, it is possible to facilitate the operation of pinching the knob to break the weakened portion.

It is a side view of the container concerning this embodiment. FIG. 2 is a plan view of the lid member of FIG. 1; FIG. 3 is a cross-sectional view of the lid member of FIG. 2 taken along line III-III. FIG. 2 is a bottom view of the lid member of FIG. 1; FIG. 2 is a cross-sectional view of the container of FIG. 1 taken along line VV. It is a bottom view of the cover member which concerns on the modification of this embodiment, and is a figure which expanded the periphery of a knob part.

Hereinafter, the container of this embodiment will be described based on the drawings.
As shown in FIG. 1 , the container 1 includes a bottomed cylindrical body member 20 in which contents are stored, a topped cylindrical lid member 10 covering the body member 20 , and attached to the bottom of the body member 20 . and a bottom member 30 . The lid member 10 closes the opening 21a (see FIG. 5) of the body member 20. As shown in FIG. The contents are not particularly limited, but liquids such as beverages can be used, for example.

In this embodiment, the body member 20 and the bottom member 30 are made of the same material, and the lid member 10 is made of a different material. As a result, when discarding the container 1, it is possible to save the trouble of sorting the parts after removing the lid member 10.例文帳に追加As the material of the body member 20 and the bottom member 30, for example, resin such as PET can be adopted. As the material of the lid member 10, for example, a resin such as polyethylene can be used.

The lid member 10 is formed with a knob portion 17 and a weakened portion 11a. The lid member 10 is configured such that when the grip portion 17 is pinched and pulled, the weakened portion 11a is broken and the tear band 18 is separated.

(direction definition)
In this embodiment, the central axis of the main body member 20 is called the container axis O. As shown in FIG. Hereinafter, the direction along the container axis O will be referred to as the vertical direction, the mouth portion 21a side of the main body member 20 in the vertical direction will be referred to as the upper side, and the bottom wall side will be referred to as the lower side. A cross section along the container axis O is called a vertical cross section.
Further, in a plan view viewed from above and below, a direction intersecting the container axis O is called a radial direction, and a direction rotating around the container axis O is called a circumferential direction. One direction in the circumferential direction is called a first direction R1, and the direction opposite to the first direction R1 is called a second direction R2 (see FIG. 2). In this embodiment, the weakened portion 11a is broken when the knob portion 17 is pinched and pulled in the first direction R1.

As shown in FIG. 5, the main body member 20 has a tubular main body tubular portion 21 extending in the vertical direction. An upper end opening of the body tubular portion 21 is the above-mentioned mouth portion 21a. A second convex portion 21b is formed on the outer peripheral surface of the main tubular portion 21 so as to protrude radially outward. The second convex portion 21b has an annular shape in a plan view, and faces the peripheral wall 11 of the lid member 10 in the vertical direction.

As shown in FIG. 1 , the bottom member 30 has a connection portion 33 and a skirt portion 34 . Each part of the bottom member 30 is arranged coaxially with the container axis O. As shown in FIG. The bottom member 30 and the body member 20 are connected by a connecting mechanism (not shown).
The connecting portion 33 is formed in a tubular shape extending in the vertical direction. The skirt portion 34 is formed in a tapered tubular shape whose diameter gradually increases downward from the connecting portion 33 . The outer diameter of the lower end portion of the skirt portion 34 is larger than the outer diameter of the main tubular portion 21 of the main body member 20 . The hakama portion 34 is a portion that comes into contact with a placement surface such as a desk when the container 1 is placed on the placement surface such as a desk in an upright posture (the posture shown in FIG. 1). The posture when the container 1 is placed in an upright posture can be stabilized by the hakama portion 34 .

As shown in FIGS. 1 to 3, the lid member 10 has a peripheral wall 11, an annular portion 12, an inner wall portion 13, a closing portion 14, and a canopy portion 15. As shown in FIGS. The lid member 10 is arranged coaxially with the container axis O as a whole.
The peripheral wall 11 is formed in a tubular shape extending in the vertical direction, and is fitted to the mouth portion 21a of the main body member 20 from the radial outside (see FIG. 5). A weakened portion 11a is formed in the central portion of the peripheral wall 11 in the vertical direction. The weakened portion 11a is a slit extending in the circumferential direction, and the peripheral wall 11 can be broken along the weakened portion 11a. The weakened portion 11 a is formed over the entire circumference of the peripheral wall 11 .

A fitting protrusion 11b is formed on the inner peripheral surface of the peripheral wall 11 so as to protrude radially inward. The fitting protrusion 11b is positioned below the weakened portion 11a. The fitting protrusions 11 b intermittently extend over the entire circumference of the peripheral wall 11 and are undercut-fitted to the second protrusions 21 b formed on the main body member 20 . In addition, the fitting projection 11b may be formed continuously over the entire circumference of the peripheral wall 11 . That is, the fitting protrusion 11b may be annular.

The annular portion 12 extends radially inward from the upper end portion of the peripheral wall 11 and has an annular shape in plan view. The annular portion 12 is in contact with the upper end portion of the body member 20 from above.
The inner wall portion 13 is formed in a vertically extending tubular shape and extends downward from the inner peripheral edge of the annular portion 12 . The inner wall portion 13 is fitted into the mouth portion 21a of the body member 20 (see FIG. 5).

The closing portion 14 extends radially inward from the lower end portion of the inner wall portion 13 and has a circular shape in plan view. The opening 21 a is closed by the closing portion 14 .
As shown in FIG. 2 , the eaves portion 15 protrudes radially outward from the peripheral wall 11 . As shown in FIG. 1, the eaves portion 15 is adjacent to the weakened portion 11a of the peripheral wall 11 and arranged above the weakened portion 11a.

As shown in FIGS. 3 and 4, the peripheral wall 11 of the lid member 10 of this embodiment is formed with a knob portion 17 and a convex portion 16 . The knob portion 17 has a projecting piece 17a, an operating projecting portion 17b, and a support portion 17c. The support portion 17c extends radially outward from the peripheral wall 11 . The protruding piece 17a protrudes in the first direction R1 from the radially outer end of the support portion 17c. The operation protrusion 17b protrudes in the second direction R2 from the radially outer end of the support portion 17c. In other words, the projecting piece 17a and the operating projecting portion 17b are supported by the support portion 17c and connected to the peripheral wall 11 by the support portion 17c.

The knob portion 17 is adjacent to the weakened portion 11a and positioned below the weakened portion 11a. With the above configuration, when the operation projection 17b is pinched and pulled in the first direction R1, force is transmitted to the weakened portion 11a through the support portion 17c, causing the weakened portion 11a to break. This makes it possible to separate the portion (opening band 18) of the peripheral wall 11 below the weakened portion 11a from the portion of the peripheral wall 11 above the weakened portion 11a. In addition, since the fitting protrusion 11b is cut off together with the opening band 18, for example, by moving the eaves 15 upward, the cover member 10 can be moved to open the opening 21a of the main body member 20. FIG.

In addition, as shown in FIG. 1, the surface of the knob portion 17 is provided with a marking portion M indicating the direction of the first direction R1 by an arrow. The marking portion M allows the user to easily recognize the first direction R1. In this embodiment, the marking portion M protrudes radially outward from the surface of the knob portion 17 . However, the form of the marking portion M can be changed as appropriate. For example, the marking portion M may be recessed radially inward from the surface of the knob portion 17, or may be provided by printing or the like.

When attaching the lid member 10 to the body member 20 , the lid member 10 is plugged from above the body member 20 . At this time, as shown in FIG. 5, the knob 17 is displaced or deformed radially outward due to the protrusion 16 coming into contact with the main tubular portion 21 . As the knob portion 17 is displaced or deformed radially outward, the amount of protrusion of the knob portion 17 radially outward becomes greater than before the cover member 10 is attached to the main body member 20 . This makes it easier to pinch the operating protrusion 17b and move it in the first direction R1.

Here, in the present embodiment, as shown in FIG. 4, the center line C2 of the projecting piece 17a and the center line C1 of the operating projecting portion 17b are radially displaced from each other in plan view. For this reason, the thickness of the connecting portion of the projecting piece 17a, the operating projecting portion 17b, and the supporting portion 17c is increased. In addition, an inclined surface 17d is formed in the connecting portion. The inclined surface 17d connects the radially outer end surface of the protruding piece 17a and the radially outer end surface of the operating protrusion 17b. As a result, the inclined surface 17d smoothly connects the steps caused by the radial positional deviation of the center line C1 and the center line C2.

In the present embodiment, the center line C2 is positioned radially outward of the center line C1, so that the inclined surface 17d faces the second direction R2 and gradually faces radially inward along the second direction R2. Inclined.
Note that the positional relationship between the center lines C1 and C2 may be reversed. That is, the centerline C2 may be located radially inward of the centerline C1. In this case, the inclined surface 17d may face the first direction R1 and may be inclined so as to gradually extend inward in the radial direction toward the first direction R1.

As described above, the knob portion 17 of the present embodiment includes the support portion 17c extending radially outward from the peripheral wall 11 and protruding in the first direction R1 from the radially outer end portion of the support portion 17c. It has a protrusion 17a and an operation protrusion 17b that protrudes in the second direction R2 from the radially outer end of the support portion 17c. In a plan view, the center line C2 of the protrusion 17a and the center line C1 of the operation protrusion 17b are displaced from each other in the radial direction. With this configuration, it is possible to increase the thickness of the connecting portion between the operation protrusion 17b and the support portion 17c in the knob portion 17, thereby enhancing the rigidity. Therefore, when the operation protrusion 17b is pinched and pulled radially outward, force is easily transmitted to the support portion 17c, and the weakened portion 11a can be broken more easily. Therefore, the operation of breaking the weakened portion 11a becomes easier.

Further, since the knob portion 17 protrudes radially outward from the peripheral wall 11 of the lid member 10, for example, when the container 1 is distributed or stored, the knob portion 17 may unexpectedly come into contact with another article, causing an external force to act. The weakened portion 11a may break. Therefore, the peripheral wall 11 of the present embodiment is provided with a canopy portion 15 that protrudes radially outward and covers at least a portion of the knob portion 17 from above. By covering the knob portion 17 from above with the eaves portion 15 in this way, it is possible to prevent the weakened portion 11a from being suddenly broken by hitting another article or the like against the knob portion 17. - 特許庁

In addition, the peripheral wall 11 is formed with a protrusion 16 that protrudes radially inward, and when the protrusion 16 comes into contact with the main body member 20, the knob 17 is deformed or displaced radially outward. is doing. With this configuration, it is possible to increase the amount of protrusion of the knob 17 to the outside in the radial direction without increasing the radial dimension of the knob 17 , thereby making it easier to grip the knob 17 . In addition, since the amount of projection of the knob portion 17 can be reduced before the lid member 10 is attached to the main body member 20, the lid members 10 can be smoothly aligned by, for example, an automatic parts feeder (parts feeder). Thus, the lid member 10 can be smoothly supplied to the next process such as an assembling machine.

Further, the knob portion 17 is formed with an inclined surface 17d that connects the radially outer end surface of the projecting piece 17a and the radially outer end surface of the operation projecting portion 17b. According to this configuration, the thickness of the connecting portion between the operation protrusion 17b and the support portion 17c can be reliably increased by the inclined surface 17d, and the rigidity of the knob portion 17 can be increased. In addition, when the operation protrusion 17b is pinched and pulled radially outward, the operation protrusion 17b is prevented from being bent from the support portion 17c, and the force can be transmitted to the support portion 17c more reliably. .

The technical scope of the present invention is not limited to the above embodiments, and various modifications can be made without departing from the scope of the present invention.

For example, in the above embodiment, the eaves portion 15 partially covers the knob portion 17 from above, but the eaves portion 15 may cover the entire knob portion 17 from above. Moreover, it is not necessary to provide such a canopy part 15 . Furthermore, the eaves portion 15 may be provided at a position where the knob portion 17 is not covered.

Further, in FIG. 4, the length of the operation protrusion 17b (the amount of protrusion from the support portion 17c) is longer than the length of the protrusion 17a (the amount of protrusion from the support portion 17c). By lengthening the operating protrusion 17b in this way, it is possible to facilitate the operation of pinching the operating protrusion 17b to break the weakened portion 11a. However, the operation protrusion 17b and the protrusion 17a may have the same length.

Further, as shown in FIG. 6, for example, ribs 17e may be provided on the knob portion 17 to further increase the rigidity of the knob portion 17. As shown in FIG. In the example of FIG. 6, the rib 17e extends over the step caused by the deviation between the center line C2 of the protrusion 17a and the center line C1 of the operating protrusion 17b. The rib 17e protrudes radially outward from the operating protrusion 17b. However, if the center line C2 of the protrusion 17a is located radially inwardly of the center line C1 of the operating protrusion 17b, the rib 17e may protrude radially outward from the protrusion 17a.
By increasing the rigidity of the knob portion 17 with such ribs 17e, when the operation protrusion 17b is operated, the force is more easily transmitted to the support portion 17c, and the weakened portion 11a can be broken more reliably.

In addition, it is possible to appropriately replace the components in the above-described embodiment with known components without departing from the scope of the present invention, and the above-described embodiments and modifications may be combined as appropriate.
