Description

  The present invention relates to a cap used for a plastic bottle or the like.

  In recent years, caps of various sizes have been used for containers such as beverage food tubes, all of which are configured to separate the cap from the perforations applied to the fixed portion of the cap. For this reason, even if it is an adult, when a hand is wet, a cap slips and it is difficult to open it instantly, and it is not easy for an elderly woman who has no hand strength, a child, or a handicapped person. For this reason, conventionally, in order to facilitate the opening and closing of the cap, a plastic bottle cap in which a plurality of anti-slip fins are attached to the side peripheral surface of the cap body and the cap body (for example, patent) Reference 1) has been devised.

Utility Model Registration No. 3109446

  The biggest advantage of the rotary cap is that it is possible to ingest the drinking water and seasonings contained in the container at any time according to the situation of the place. However, in order to open the cap using a separate device, it is necessary to carry the separate device, and there is a problem in that the work is complicated and complicated for the elderly and children. Further, the cap described in Patent Document 1 has a problem in that each fin is provided so as to extend straight from the upper end to the lower end of the cap, so that a finger may be displaced along the fin and it may be difficult to open the cap. .

  The present invention has been made paying attention to such a problem, and provides a cap that can be easily applied and easily opened and closed even if the finger strength of the elderly or children is weak. For the purpose.

  In order to achieve the above object, a cap according to the present invention has a non-slip protrusion on the side surface of a cap body having an internal thread on the inner periphery, and the protrusion is in the height direction of the cap body. The projecting portions branched in a bifurcated manner from the middle portion to the upper end or the lower end, and are bent to the opposite sides in the circumferential direction.

  The cap according to the present invention is used for containers such as plastic bottles. The cap according to the present invention can be easily opened and closed by putting a finger on the anti-slip protrusion provided on the side surface of the cap body. Since the protruding portion is bifurcated from the middle portion of the cap body to the upper end or the lower end, it is easy to put a finger on either side of the protruding portion. For this reason, both when opening and closing, it is easy to apply a force to the protruding portion, and it is easy to turn the cap body. Thus, the cap according to the present invention is easy to apply force and can be easily opened and closed even if the hand is weak, such as an elderly person or a child.

  In the cap according to the present invention, the protrusion has a reinforcing action on the cap body, and the strength of the cap body can be increased. In the cap according to the present invention, it is preferable that the protrusions are composed of a plurality of, particularly three or more. When there are three protrusions and a thumb, index finger, and middle finger can be put on each protrusion, the force of each finger can be transmitted to the cap body at the same time. For this reason, it can be opened and closed efficiently with a lighter force.

  In the cap according to the present invention, it is preferable that the protruding portion protrudes so as to coincide with the side surface at an upper end and a lower end of the cap body and gradually increase toward the intermediate portion. In this case, the finger force can be concentrated on the middle part of the cap body without being dispersed, and can be opened and closed more easily. In addition, since the protrusions coincide with the side surfaces at the upper end and the lower end of the cap body and the protrusion does not have a corner angle, it is possible to prevent finger injury due to the corner angle. In particular, when used in PET bottle caps and dropped by a vending machine to an outlet, even if a child puts a hand in the outlet, the cap does not have a corner, making it difficult to cause severe injury. The protrusion is less likely to break.

  In the cap according to the present invention, it is preferable that the protrusion has a thickness that gradually decreases from the intermediate portion to the upper end and the lower end of the cap body. In this case, since the protrusion is thick at the intermediate portion of the cap body, it can be concentrated on the intermediate portion of the cap body without dispersing the finger force, and can be opened and closed with a lighter force.

  In the cap according to the present invention, it is preferable that a side surface of the protrusion is smoothly curved from the upper end to the lower end of the cap body. In this case, when a finger is put on the protrusion, the finger can easily fit along the shape of the protrusion. For this reason, it is easy to turn a cap main body and it can open and close more easily.

  In the cap according to the present invention, it is preferable that the cap body is a cap of a beverage plastic bottle, and a plurality of the protrusions are provided at equal intervals around the cap body. In this case, the cap body can be evenly reinforced by the protrusions to increase the strength.

  ADVANTAGE OF THE INVENTION According to this invention, even if it is a person with weak finger | toe strengths, such as an elderly person and a child, the cap which can apply force easily and can be opened and closed easily can be provided.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows a cap according to an embodiment of the present invention.
As shown in FIG. 1, the cap 10 is a cap 10 used for a container 1 such as a beverage plastic bottle, and includes a cap body 11, a fixing portion 12, and three anti-slip protrusions 13. Yes.

  The cap body 11 is provided with a female screw on the inner periphery, and is detachably attached to the mouth of the container 1 provided with a screw on the outer periphery of the mouth. The cap body 11 is provided with a knurled notch 11a for preventing slipping that extends in the height direction from the upper end to the lower end on the side surface. The fixing portion 12 has a ring shape and is provided at the base of the mouth portion of the container 1. Since the fixed portion 12 has a smaller diameter than the outer periphery of the mouth portion of the container 1, it does not come off from the mouth portion. The cap body 11 is provided at the lower end edge at the upper end edge of the fixing portion 12 so as to be separated by a perforated joint. The cap 10 can be opened by rotating the cap body 11 counterclockwise so that the cap body 11 is separated from the fixing portion 12.

  Each protrusion 13 is provided on the side surface of the cap body 11 so as to extend in the height direction of the cap body 11. The cap main body 11 is bifurcated from an intermediate portion 13a between the upper end and the lower end to the lower end, and the side surface of the cap main body 11 is smoothly curved from the upper end to the lower end. The branched protrusions 13 are bent on the opposite sides in the circumferential direction. Each protrusion 13 coincides with the side surface at the upper end and the lower end of the cap body 11, and protrudes so as to gradually increase toward the intermediate portion 13a. Therefore, each protrusion 13 has a protrusion amount from the side surface of the cap body 11 of 0 at the upper end and the lower end of the cap body 11 and the maximum at the intermediate portion 13a. Each protrusion 13 is thickest at the intermediate portion 13a, gradually decreases from the intermediate portion 13a to the upper end and the lower end of the cap body 11, and becomes zero at the upper end and the lower end. The protrusions 13 are provided around the cap body 11 at equal intervals.

Next, the operation will be described.
The cap 10 can be easily opened and closed by placing a finger on each protrusion 13 provided on the side surface of the cap body 11. Since each protrusion 13 is bifurcated from the middle part 13a of the cap body 11 to the lower end, it is easy to get a finger from either the left or right of each protrusion 13. In addition, since each protrusion 13 has a smoothly curved side surface, when the finger is put on each protrusion 13, the finger can easily fit along the shape of the protrusion 13. For this reason, both when opening and closing, it is easy to apply a force to each protrusion 13, and the cap body 11 is easy to turn. As described above, the cap 10 can be easily opened and closed easily even if it is a weak person such as an elderly person, a child, or a handicapped person.

  The cap 10 can hang a thumb, index finger, and middle finger on each of the three protrusions 13, and can simultaneously transmit the force of each finger to the cap body 11. For this reason, it can be opened and closed efficiently and easily. Further, the cap 10 is an intermediate portion 13a between the upper end and the lower end of the cap body 11, and the protrusion amount from the side surface of the cap body 11 is the largest and the thickness is the largest, so that the finger force is not dispersed. It can be concentrated on the middle part of the cap body 11 and can be opened and closed more easily. In addition, each protrusion 13 coincides with the side surface at the upper end and the lower end of the cap body 11, the protrusion amount is 0, and each protrusion 13 does not have a corner, so that it is possible to prevent finger injury due to the corner. . In particular, when it is used for a PET bottle cap and falls to the outlet with a vending machine, even if the child puts a hand in the outlet, the cap 10 has no corner, so it is difficult to cause severe injury, Further, the protrusion 13 is hardly damaged.

  In the cap 10, each protrusion 13 has a reinforcing action on the cap body 11, and the strength of the cap body 11 can be increased. For this reason, even if the material used for the cap body 11 is reduced, it is possible to maintain the strength equal to or higher than that in the case where there is no protrusion 13 and to save resources. In addition, by devising the thickness, shape, number, and arrangement of the protrusions 13, it is possible to minimize the increase in materials used due to the increase in size and weight of the cap body 11.
