Description

The present invention relates to a device for easily rotating and opening a cap of a PET bottle.

Generally, beverages such as tea, juice, and natural water are widely sold in a so-called PET bottle, which is sealed in a plastic bottle container and the opening of the bottle container is sealed with a screw lid-shaped cap. However, this type of bottled beverage is tightly tightened and screwed into the cap to ensure internal airtightness, and is sealed with the lower edge of the cap connected to the lower ring member.
The opening of such a bottle is generally performed by grasping the cap with a finger and rotating the cap while disconnecting the connection portion with the ring member, but the cap is tightly tightened and screwed as described above. Since it is connected to the ring member at the same time, it is difficult to open it for elderly people, children, and people with weak fingers such as paralysis of fingers.

In order to solve such a problem, the invention relating to "PET bottle cap opener" is described in Japanese Patent Application Laid-Open No. 3047967, and "PET bottle mouth cap and can tab opening device" is published in Japanese Patent Application Laid-Open No. 2001-114395. The invention relating to "PET bottle cap opener" is described in JP-A-2003-300597, and the invention relating to "PET bottle-dedicated opener" is described in JP-A-2004-203478. The inventions relating to the "water bird type screw lid opener" are disclosed in the publication.

The inventions and the like disclosed in these publications are essentially devices that increase the coefficient of friction applied to the cap to make it easier to rotate the cap, but the present invention provides this at a lower cost. , The purpose is that it can also be used as a coaster on which glasses and cups are placed.

The present invention relates to a cap opener for easily rotating and opening a cap of a PET bottle, and which can also be used as a coaster on which a glass, a cup, or the like is placed.

The present invention is a cap opener used when opening a screw cap-shaped sealing cap of a sealed container such as a PET bottle, and is composed of a flexible flat base member having a predetermined thickness. In the substantially central portion of the above, a slit portion having a predetermined length and a predetermined width was excavated, and small holes were provided at both ends of the slit portion in the longitudinal direction in order to prevent the crack from expanding. The base member is related to a cap opener, which is characterized in that it can also be used as a coaster on which a glass, a cup, or the like is placed.
It is preferable to use a soft rubber or resin material for the flexible flat base member having a predetermined thickness because it can be manufactured at low cost and can withstand repeated use, and the thickness thereof is 2 It is preferably about 6 mm from the viewpoint of usability, and it is preferable to be able to obtain a circular or polygonal planar shape from the viewpoint of the property of being used as a coaster.

The slit portion having the predetermined length and the predetermined width has a length of 1/2 to 3/4 of the plane width at the portion of the base member provided with the slit portion, and the width is 0.5 to 1. It is preferably about 0 mm.
If such a slit portion is simply excavated in a material such as soft rubber or resin, cracks will expand from both ends in the longitudinal direction of the slit portion, and therefore, as described above, both ends in the longitudinal direction of the slit portion will be formed. Is provided with a small hole in order to prevent the crack from expanding in the slit.

Of course, it is also possible to apply so-called embossing on the surface of the planar base member to increase friction, or to provide vertical grooves for increasing friction on both inner surfaces of the slit portion.
In addition, although the description is given in this specification as a cap opener for a PET bottle container for beverages for convenience of explanation, a cap for a glass container or a liquid seasoning using a similar screw cap-shaped sealing cap is used. Of course, it is also possible to use the PET bottle cap opener according to the present invention for opening the cap.

That is, the user inserts a PET bottle cap into the slit portion while widening the slit portion excavated in the substantially central portion of the base member so as to push open, and then the cap surface of the base member. The cap is rotated by covering most of the cap and increasing the coefficient of friction applied to the cap.
By covering most of the cap surface with the base member, it is possible to rotate the cap with less force in addition to increasing the diameter of the cap in a pseudo manner, and in particular, the force of the finger. For people with weakness, it is easy to rotate the cap so that it can be grasped with the palm.

Further, since the base member can take a circular or polygonal planar shape, the cap opener according to the present invention can also be used as a coaster on which a glass, a cup, or the like is placed.
Circular or polygonal flat coasters made of soft rubber or resin materials are already generally manufactured and sold at low cost for applications such as novelty, and the slit portion is excavated in the slit portion. The PET bottle cap opener according to the present invention can be provided at low cost because only a step of providing small holes at both ends in the longitudinal direction is added.

FIG. 1 is a plan view of a cap opener according to the present invention.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. Needless to say, various changes and / or additions can be made to these embodiments as long as they do not deviate from the technical idea of the present invention.
For example, molding the planar base member into a substantially flower shape or a substantially animal shape is also free as long as the effect of the present invention is not impaired.

FIG. 1 is a plan view of a cap opener according to an embodiment of the present invention.
As shown in FIG. 1, a slit portion 2 having a predetermined length and a predetermined width is excavated in a substantially central portion of the base member 1 in a plan view having a substantially quadrangular planar shape, and the slit portion 2 is formed. Small holes 3 are provided at both ends in the longitudinal direction in order to prevent the slit from expanding.
The user inserts a PET bottle cap into the slit portion 2 while widening the slit portion 2 excavated in the substantially central portion of the base member 1 so as to push open the slit portion 2, and then uses the base member 1. The cap is rotated by covering most of the surface of the cap and increasing the coefficient of friction applied to the cap.
By covering most of the surface of the cap with the base member 1, it is possible to rotate the cap with less force in addition to increasing the diameter of the cap in a pseudo manner, and especially for the fingers. For people with weak power, it is easy to rotate the cap as if holding it with the palm.

In various prototypes by the inventor, when the length of the slit portion 2 is 50 mm to 60 mm and the width is 0.5 mm in the planar base member 1 having a 90 mm square and a thickness of 4 mm, about 350 generally available on the market. A particularly suitable usability was obtained for use with a cap of a PET bottle having a capacity of milliliter to about 2 liter.
