Summary of the Invention
Problems to be Solved by the Invention
[0004] However, in the conventional pouring cap, when inserting a finger inside the ring body with the back of the finger facing backward and pulling up the ring body, the rear end portion of the upper end of the ring body to which the connecting portion is connected may be pressed against the back of the finger, causing pain.
[0005] The present invention has been made in view of the above circumstances, and an object thereof is to provide a pouring cap that can suppress pain felt on the back of the finger when inserting a finger into the ring body and pulling up the ring body.
Means for Solving the Problems
[0006] To solve the above problems, the present invention employs the following means. Specifically, the dispensing cap of the present invention has a covering plate that closes the mouth of a container body that contains contents, the covering plate has a dispensing hole that penetrates in the vertical direction and is connected to a closing plate via a breakable weakening portion that closes the dispensing hole so that it can be opened, a ring body that opens in the vertical direction is provided above the closing plate, the rear ends of the ring body and the closing plate are connected to each other via a connecting portion that extends in the vertical direction, a notch is formed at the rear end of the ring body that opens upward and penetrates in the front-to-back direction, and each part of the ring body that is connected to both sides in the circumferential direction along the ring body with respect to the notch is a thin-walled part that is thinner than the other parts.
[0007] According to the present invention, since a notch is formed at the rear end of the ring body, when inserting a finger into the inside of the ring body with the back of the finger facing backward and pulling up the ring body, it becomes possible to insert the finger downward into the notch, thereby suppressing the vertical pressing force applied to the back of the finger from the upper end of the ring body. In the ring body, each part that runs along the circumferential direction around the notch is formed as a thin-walled section, which is thinner than the other parts. As mentioned above, when pulling up the ring body with your finger, even if the rear end of the ring body is pressed vertically against the back of your finger, the thin-walled section elastically deforms, making it easier for the notch to expand circumferentially. This reduces the vertical pressure applied from the ring body to the back of the finger, thus preventing pain on the back of the finger.
[0008] Of the outer peripheral edge of the thin-walled portion of the ring body as viewed from the radial direction, the upper end portion extending in the circumferential direction and the circumferential end portion extending in the vertical direction that defines the notch portion may be curved toward the outside of the ring body.
[0009] In this case, the outer edge of the thin-walled portion of the ring body, as viewed from the radial direction, has an upper end that extends in the circumferential direction and a circumferential end that extends in the vertical direction and defines the notch, which is curved outwards from the ring body. This makes it easier to insert a finger into the ring body, for example, by preventing a splinter from catching on the upper end of the ring body. Furthermore, as mentioned above, when pulling up the ring body with a finger, even if the upper end of the thin-walled portion is pressed against the back of the finger in the vertical direction, it is less likely to dig into the back of the finger.
[0010] The portion of the inner circumferential surface of the ring body adjacent to the thin-walled portion, and the thin-walled portion itself, may be continuous without any steps.
[0011] In this case, since the portion of the inner circumference of the ring body adjacent to the thin-walled portion, and the thin-walled portion itself, are continuous without any steps, it is possible to eliminate the stepped portion that would strongly press against the finger when pulling up the ring body with the finger, thereby reducing the pain felt by the finger. Furthermore, it becomes easier to elastically deform the thin-walled portion toward the outside of the ring body by inserting the finger inside the ring body.
[0012] The circumferential size of the notch increases from bottom to top, and the connection portion between the upper end extending in the circumferential direction and the circumferential end extending in the vertical direction and defining the notch, of the outer peripheral edge of the thin-walled portion of the ring body as viewed from the radial direction, may be formed in a curved shape that protrudes toward the notch.
[0013] In this case, the circumferential size of the notch increases from bottom to top, and the connecting portion of the outer edge of the thin-walled part of the ring body, viewed from the radial direction, is formed in a curved shape that protrudes toward the notch. As described above, when pulling up the ring body with your finger, it becomes possible to slide your finger smoothly against the connecting portion of the thin-walled part with less snagging, and to insert it downward into the notch, thereby reliably preventing pain on the back of your finger. [Effects of the Invention]
[0014] According to this invention, it is possible to reduce the pain felt on the back of the finger when inserting a finger into the ring and pulling the ring up. [Brief explanation of the drawing]
[0015] [Figure 1] This is a top view of the dispensing cap of one embodiment with the lid open. [Figure 2] This is a cross-sectional view taken along the line II-II in Figure 1. [Figure 3] Figure 1 is a partial perspective view of the ring-shaped body. [Modes for carrying out the invention]
[0016] An embodiment of the dispensing cap will be described below with reference to the drawings. As shown in Figures 1 to 3, the dispensing cap 1 according to this embodiment comprises a mounting cylinder 13 that is attached to the mouth W1 of the container body W in which the contents are contained, and a cap body 15 having a dispensing hole 14 that communicates with the inside of the container body W. The container body W is formed in a bottomed cylindrical shape, and the cap body 15 is formed in a topped cylindrical shape. The container body W and the cap body 15 are arranged coaxially with the common axis O. Hereinafter, the direction along the common axis O will be referred to as the vertical direction, the direction intersecting the common axis O when viewed from the vertical direction will be referred to as the radial direction, and the direction revolving around the common axis O will be referred to as the circumferential direction.
[0017] A lid 27 is connected to the cap body 15 via a hinge portion 26. By rotating the lid 27 vertically around the hinge portion 26, the lid 27 opens and closes the dispensing hole 14. Alternatively, a lid that is detachably screwed onto the cap body 15 may be used without the hinge portion 26. Hereinafter, in the radial direction, the side where the hinge portion 26 is located relative to the common axis O will be referred to as the rear, and the opposite side will be referred to as the front.
[0018] The cap body 15 includes a covering cylinder 28 that covers the mounting cylinder 13 from the outside in the radial direction. As shown in FIG. 1, a part of the circumferential direction of each of the mounting cylinder 13 and the covering cylinder 28 is connected via a non-breakable fixing portion 15b. The fixing portion 15b is provided at a position adjacent to the hinge portion 26 in the circumferential direction. The lower end portions of the mounting cylinder 13 and the covering cylinder 28 are connected via breakable connecting pieces 15a. A plurality of connecting pieces 15a are provided at intervals in the circumferential direction. The covering cylinder 28 and the mounting cylinder 13 are integrally formed. In the state where the lid body 27 is opened, the lid body 27 is pulled together with the covering cylinder 28 via the hinge portion 26, and the cap body 15 can be separated from the container body W by pulling up the mounting cylinder 13 with respect to the mouth portion W1 through the fixing portion 15b while breaking the plurality of connecting pieces 15a.
[0019] The top wall portion 22 of the cap body 15 includes an annular plate portion 23, a sealing cylinder portion 24, a covering plate 25, and a pouring cylinder 21.
[0020] The annular plate portion 23 extends from the upper end portion of the mounting cylinder 13 toward the inside in the radial direction. The annular plate portion 23 is disposed at the upper end opening edge of the mouth portion W1. The sealing cylinder portion 24 extends downward from the inner peripheral edge portion of the annular plate portion 23. The sealing cylinder portion 24 is closely fitted into the mouth portion W1. The covering plate 25 is provided on the inner peripheral surface of the sealing cylinder portion 24 and closes the inside of the mouth portion W1. A pouring hole 14 penetrating in the vertical direction is formed in the covering plate 25. The pouring cylinder 21 extends upward from the inner peripheral edge portion of the annular plate portion 23. The rear portion 21a of the upper end portion of the pouring cylinder 21 extends downward as it goes toward the rear end along the circumferential direction. The pouring cylinder 21 may be provided on the upper surface of the covering plate 25 and surround the pouring hole 14 from the outside in the radial direction, or the pouring cylinder 21 may not be provided.
[0021] The covering plate 25 is provided with a closing plate 25b connected via a breakable weakened portion 25a, which also closes the dispensing hole 14 in a way that allows it to be opened. The closing plate 25b is connected to the inner circumferential surface of the dispensing hole 14 via the weakened portion 25a. The weakened portion 25a is formed as a thin wall that extends continuously along the inner circumferential surface of the dispensing hole 14 when viewed from above or below. A ring-shaped body 29, which is open in the vertical direction, is provided above the closing plate 25b. The ring-shaped body 29 is arranged coaxially with the common axis O.
[0022] The rear ends of the ring body 29 and the closing plate 25b are connected to each other via a connecting portion 25c that extends in the vertical direction. The connecting portion 25c is connected to the inner circumferential surface of the rear end of the ring body 29. Furthermore, the circumferential positions of the connecting portion 25c and the hinge portion 26 may be different from each other. For example, the hinge portion 26 and the connecting portion 25c may be provided separately on both sides of the common axis O in the radial direction.
[0023] Anti-slip ribs 29b are formed on the inner circumferential surface of the front end of the ring body 29. The anti-slip ribs 29b are formed in a circumferentially extending, ridge-like shape, and multiple ribs are formed at intervals in the vertical direction. The anti-slip ribs 29b are provided in the middle of the ring body 29 in the vertical direction. A buffer piece 29c is formed at the lower end opening of the front end of the ring body 29, projecting downward. The buffer piece 29c is formed in a circumferentially extending ridge shape, and multiple buffer pieces are formed at intervals in the circumferential direction. The buffer piece 29c is formed to be elastically deformable. When pulling up the ring body 29 with a finger, the buffer piece 29c can be brought into contact with the pad of the finger, thereby mitigating the vertical pressure applied to the pad of the finger and reducing the feeling of pain in the pad of the finger.
[0024] In this embodiment, a notch 29a is formed at the rear end of the ring body 29, opening upward and extending in the front-to-back direction. The circumferential size of the notch 29a increases from bottom to top. The circumferential sizes of the lower end of the notch 29a and the connecting portion 25c are equal. The circumferential centers of the lower end of the notch 29a and the connecting portion 25c coincide with each other. As shown in Figure 2, the lower end of the notch 29a is located above the upper end of the connecting portion 25c and is adjacent to it in the vertical direction. The portion of the upper end of the ring body 29 located in front of the notch 29a is positioned above the rear end of the dispensing cylinder 21. The lower end of the notch 29a is positioned below the rear end of the upper end of the dispensing cylinder 21.
[0025] Of the ring body 29, each portion that is connected to both sides of the notch 29a in the circumferential direction is a thin-walled portion 11 formed to be thinner than the other portions. The portion of the inner circumferential surface of the ring body 29 adjacent to the thin-walled portion 11, and the thin-walled portion 11 are connected without any steps. That is, the thin-walled portion 11 is formed by the outer circumferential surface of the ring body 29 being recessed radially inward.
[0026] As shown in Figure 3, the connection portion 11c of the outer peripheral edge of the thin-walled portion 11, viewed from the radial outside, is formed in a curved, protruding shape toward the notch portion 29a, between the upper end portion 11a extending in the circumferential direction and the circumferential end portion 11b extending in the vertical direction and defining the notch portion 29a. These upper end portion 11a, circumferential end portion 11b, and connection portion 11c are curved toward the outside of the ring body 29, as shown by the dashed line in Figure 2, for example.
[0027] As shown in Figure 3, of the outer peripheral edge of the thin-walled portion 11 as viewed from the radial outside, the opposing portion 16 that faces the open end 12, which consists of the upper end 11a, the circumferential end 11b, and the connecting portion 11c, extends upward from the lower end of the circumferential end 11b, moving away from the notch 29a along the circumferential direction, and is connected to the upper end 11a. When viewed from the radial outside, the opposing portion 16 has a curved shape that protrudes downward. The circumferential size of the thin-walled portion 11 is larger than the vertical size of the thin-walled portion 11.
[0028] As described above, with the dispensing cap 1 according to this embodiment, since a notch 29a is formed at the rear end of the ring body 29, when inserting a finger into the inside of the ring body 29 with the back of the finger facing backward and pulling up the ring body 29, it becomes possible to insert the finger downward into the notch 29a, thereby suppressing the vertical pressing force applied to the back of the finger from the upper end of the ring body 29.
[0029] Of the ring body 29, each portion connected to both sides of the notch 29a in the circumferential direction is formed as a thin-walled portion 11, which is thinner than the other portions. As described above, when the ring body 29 is pulled up with the finger, even if the rear end of the ring body 29 is pressed vertically against the back of the finger, the thin-walled portion 11 elastically deforms, making it easier for the notch 29a to expand in the circumferential direction. This reduces the vertical pressing force applied from the ring body 29 to the back of the finger, thereby preventing pain on the back of the finger.
[0030] Of the outer peripheral edge of the thin-walled portion 11 as viewed from the radial direction, the upper end portion 11a extending in the circumferential direction and the circumferential end portion 11b extending in the vertical direction and defining the notch portion 29a are curved toward the outside of the ring body 29. This makes it possible to insert a finger into the inside of the ring body 29, for example, by preventing a hangnail from catching on the upper end portion of the ring body 29, and as mentioned above, even if the upper end portion of the thin-walled portion 11 is pressed against the back of the finger in the vertical direction when pulling up the ring body 29 with a finger, it is less likely to dig into the back of the finger.
[0031] Since the portion of the inner circumferential surface of the ring body 29 adjacent to the thin-walled portion 11, and the thin-walled portion 11 itself, are continuous without any steps, it is possible to eliminate any stepped portion that would strongly press against the finger when pulling up the ring body 29 with the finger, thereby reducing pain to the finger. Furthermore, it becomes easier to elastically deform the thin-walled portion 11 toward the outside of the ring body 29 by inserting the finger inside the ring body 29.
[0032] The circumferential size of the notch 29a increases from bottom to top, and the connecting portion 11c of the outer peripheral edge of the thin-walled portion 11, viewed from the radial direction, is formed in a curved shape that protrudes toward the notch 29a. As described above, when pulling up the ring body 29 with a finger, it becomes possible to slide the finger smoothly against the connecting portion 11c of the thin-walled portion 11 with less snagging, while simultaneously inserting it downward into the notch 29a, thereby reliably preventing pain on the back of the finger.
[0033] Furthermore, the technical scope of the present invention is not limited to the embodiments described above, and various modifications can be made without departing from the spirit of the invention.
[0034] The closing plate 25b may be formed to be larger than the dispensing hole 14 when viewed from above, and may be connected to the upper surface of the covering plate 25 via weakening portions intermittently provided along the outer circumferential surface of the closing plate 25b. The open end 12 of the outer peripheral edge of the thin-walled portion 11, as viewed from the radial direction, does not necessarily have to be curved outward from the ring body 29. The thin-walled portion 11 is formed by at least one of the inner and outer circumferential surfaces of the ring body 29 being recessed in the radial direction, and is not limited to the above embodiment; it may be modified as appropriate. The shape of the thin-walled portion 11 when viewed from the radial direction may be, for example, circular or rectangular. The shape and size of the notch 29a are not limited to the above embodiment and may be changed as appropriate, as long as the notch 29a is sandwiched in the circumferential direction by the thin-walled portion 11.
[0035] Furthermore, without departing from the spirit of the present invention, the components in the above embodiments may be replaced with well-known components as appropriate, and the above embodiments and modifications may be combined as appropriate. [Explanation of symbols]
