SOLUTION: In a cap 1 for a tube to be used for a tube filled with paint or toothpaste formed in a drumlike shape with its one end being a closed end 2 while the other end being an open end 3 where a relation of its overall length (a) to its maximum width (b) is a<=b, a plurality of ribs 4, each extending from the open end 3 to the closed end 2, are formed at the external wall at its side, and extensions 5, each projecting beyond the closed end 2, are provided at the ribs 4. Therefore, when the cap 1 is swallowed erroneously and the inside of a throat is blocked with the cap 1, passage is ensured for air with grooves 6 and 7 between the ribs 4 and between the extensions 5, and thereby suffocation is prevented.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tube cap used for a tube filled with paints such as paints and poster colors, daily products such as toothpaste and shampoo, and food products such as seasonings and spices.

[0002]

2. Description of the Related Art Conventionally, a tube cap is known which has a closed end at one end and an open end at the other end and has the same ratio of the total length to the maximum width or a longer maximum width.
Further, various improvements have been made in terms of design and advantages in use. For example, it is known that the outer side wall of the cap is provided with a rib extending from one end to the other end so that the hand does not slip when the cap is opened and closed.

By the way, in recent years, many applications have been made regarding caps for the purpose of preventing choking due to accidental ingestion by infants and the like. For example, in Japanese Utility Model Laid-Open No. 5-46486, "a plurality of vertical grooves are provided in the axial direction from the cap closed end, and one end of the vertical groove is provided on the outer surface of the cap opening side through a plurality of ribs. A writing instrument cap having a tube integrally provided therein is disclosed. Most caps intended to prevent suffocation due to such accidental ingestion are caps for writing instruments such as felt-tip pens and markers, and this type of cap usually has a total length longer than the diameter.
A slender type is used. Therefore, the air flow passage is formed only in the longitudinal direction from the closed end to the open end.

[0004]

If the cap used in the tube has the same ratio of the total length to the maximum width or the maximum width is longer, it is assumed that the cap is accidentally swallowed and gets stuck in the throat.
The following two cases are possible. The first case is in the vertical direction, that is, the case where the side surface of the cap is in contact with the throat wall, and the second case is in the lateral direction, that is, the case where the end surface of the cap is in contact with the throat wall.

On the other hand, in the above-described conventional suffocation preventive cap, since the air flow passage is formed only in the longitudinal direction from the closed end to the open end, air may not flow depending on the direction in which the cap is clogged. There is. That is, when the configuration of the choking prevention cap for a writing instrument that has been conventionally proposed is applied to a tube cap, the intended purpose of preventing choking may not be achieved.

The present invention provides a cap for a tube intended to prevent suffocation by allowing air to flow regardless of the direction in which the cap is clogged if the cap is temporarily clogged by accidental ingestion. This is an issue.

[0007]

DISCLOSURE OF THE INVENTION The present invention relates to a tubular tube cap in which one end is a closed end and the other end is an open end, and the ratio of the total length to the maximum width is the same or the maximum width is longer. A gist is a tube cap characterized in that a plurality of ribs extending from one end to the other end are provided on a side surface outer wall, and a projection from the end surface is provided on part or all of these ribs. is there.

[0008]

When the side surface of the tube cap of the present invention comes into contact with the inner wall of the throat and becomes clogged, the groove formed by the rib extending from one end to the other end of the outer wall of the side surface serves as an air circulation groove. When the end surface comes into contact with the inner wall of the throat and becomes clogged, the groove formed by the protruding portion from the end surface extending to the rib serves as an air circulation groove, which is related to the direction of the cap when swallowed. It is possible to secure the circulation of air.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the accompanying drawings. 1 and 2 show a first embodiment of the present invention. 1 is a vertical sectional view of the first embodiment, and FIG. 2 is a sectional view taken along the line AA of FIG. The cap 1 is a cylindrical body having one end as a closed end 2 and the other end as an open end 3, and is made of synthetic resin or metal. The total length a and the maximum width b of the cap 1 are the total length a ≦
It has the relationship of the maximum width b. A plurality of ribs 4 extending from the open end 3 to the closed end 2 are formed on the outer side wall of the cap 1. A projecting portion 5 projecting from the closed end 2 is extended to the rib 4.

The cap 1 has a female screw formed on its inner wall, and is intended to be fastened to a tube (not shown) by screwing, but the method of fastening the cap 1 and the tube is the same as the above-mentioned screwing. In addition to this, a conventionally known method such as press fitting or fitting and fixing with ribs can be adopted. In addition, in the first embodiment, the protruding portions 5 are provided so as to extend over all the ribs 4, but the number of the extending portions 5 is appropriately set according to the required air circulation amount and the like. Can be set. The size and the number of the ribs 4 can also be appropriately set according to the required air circulation amount.

When the cap 1 according to the first embodiment is accidentally swallowed, and when the cap 1 is vertically clogged in the throat,
When air circulates through the groove 6 formed between the ribs 4 and between the protrusions 5 to prevent suffocation and is blocked in the lateral direction, it is surrounded by the groove 6 formed by the protrusions 5 and the protrusions 5. Since air circulates through the space 7 outside the closed end 2 that is closed, suffocation can be prevented.

A second embodiment of the present invention is shown in FIGS.
FIG. 3 is a longitudinal sectional view of the second embodiment, and FIG. 4 is A- of FIG.
FIG. 3 is a sectional view taken along line A. The second embodiment is different from the first embodiment in that the closed end 1 is attached to the protruding portion 15 protruding from the closed end 12.
The second embodiment is the same as the first embodiment except that the extension 15a extending toward the center of the second member is formed. In the second embodiment, the protrusion 15 on the closed end 12 side is formed with the extension 15a toward the center of the closed end 12, so the cross-sectional area of the space 17 surrounded by the closed end 12 and the protrusion 15 is narrow. Therefore, when the cap 11 is laterally blocked in the throat, the bulging of the throat wall into the space 17 is suppressed, and the air flow passage can be secured more reliably, and the choking prevention effect is further enhanced.

FIG. 5 and FIG. 6 show a third embodiment of the present invention.
FIG. 5 is a vertical cross-sectional view of the third embodiment, and FIG. 6 is A- of FIG.
FIG. 3 is a sectional view taken along line A. The third embodiment is the same as the first embodiment,
The procedure is the same as that of the first embodiment except that a columnar protrusion 28 having a circular cross section is formed at a position where the closed end 22 does not contact the protrusion 25. In the third embodiment, since the columnar protrusion 28 is formed on the closed end 22, the cross-sectional area of the space 27 formed by the closed end 22, the protrusion 25, and the columnar protrusion 27 is the same as in the first embodiment, that is, the columnar protrusion. Since it becomes narrower than when 27 is not formed, swelling of the throat wall to the space 27 is suppressed when the cap 21 is laterally clogged in the throat, and an air flow passage can be more reliably secured and choking is prevented. The effect is also higher.

Here, the columnar protrusion 27 in the third embodiment is used.
Does not need to be circular in cross section, and can be formed in any shape such as a polygon, a star, or an ellipse, and its height is such that the total length a of the cap 21 and the maximum width b are a ≦ It can be arbitrarily set within a range satisfying the relationship of b.

7 and 8 show a fourth embodiment of the present invention.
FIG. 7 is a vertical sectional view of the fourth embodiment, and FIG. 8 is A- of FIG.
FIG. 3 is a sectional view taken along line A. The fourth embodiment is the same as the first embodiment,
The procedure is the same as that of the first embodiment except that the projecting portion 35 extending to the plurality of ribs 34 is provided on the open end 33 side instead of the closed end 32. In the fourth embodiment, the open end 3 of the cap 31 is
By forming the protruding portion 35 protruding from the end surface on the 3 side,
When the cap 31 is accidentally swallowed and gets stuck laterally in the throat, the groove 36 formed by the projection 35 and the projection 35 are formed.
Air circulates in the space 37 surrounded by, that is, the inside of the cap 31, and asphyxiation can be prevented.

Since the space 37 can be formed so that its depth is substantially the same as the entire length of the cap 31, the closed end 32 is formed.
The effect of the bulging of the throat wall on the space 36 is reduced as compared with the case where the protrusion is formed on the side, and a higher choking prevention effect can be obtained.

In the tube cap according to the present invention, since the ribs are provided from one end to the other end on the outer wall of the side surface of the cap in order to form the air flow passage by the groove between the ribs, the air flow passage is provided. Should be formed so that That is, the rib is not limited to being continuously provided from one end to the other end, but may be provided with a notch so that an air flow passage can be secured.

[0018]

Since the cap according to the present invention has the above-mentioned structure, even if the cap that is accidentally swallowed gets stuck in the throat, air circulation can be ensured regardless of the direction of the swallowed cap. , Can prevent suffocation.
