Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a novel lid opening tool.
[0002]
[Prior art]
Viscous substances such as honey and lids of containers such as heat-sterilized bottles are extremely difficult to open. In particular, in the case of a person with weak grip or arm strength, such as a child or an elderly person, in addition to these containers, it is often difficult to open a lid of a slightly closed container or a small-diameter lid.
[0003]
For this reason, various lid opening devices have been proposed and marketed. However, the current situation is that there are few ideal ones of this kind of conventional one, such as complicated operation and the fact that the part to be hung on the lid does not slide for use.
[0004]
[Problems to be solved by the invention]
Accordingly, the present inventor has completed the present invention as a result of various prototype researches on a tool that can be easily and reliably opened using the force of gripping the lid.
[Means for Solving the Problems]
That is, the lid opening device of the present invention is a belt-like body having a size that can be wound once or multiple times around the lid of the container, and is attached to the inner side surface of one end of the belt-like body to temporarily adhere to the side surface of the container lid. The main point is to provide a section. Then, this attachment part is temporarily fixed to an arbitrary position on the side surface of the container lid, and the belt-like body is wound around the opening direction starting from there, and the belt-like body portion is gripped with one hand or sandwiched with both hands and opened as it is. When it is turned, the lid is easily opened.
[0006]
In general, the opening device requires both a pressing force for pressing the opening member against the container lid and a force (rotational moment) for rotating the opening member. By the way, in order to transmit the rotational force of the opening lid member to the container lid, a frictional force between them is required. The source of this frictional force is the pressing force. That is, a force for grasping and turning the opening cover is required. The person unconsciously adjusts the power of both.
[0007]
However, this adjustment is difficult for people who do not work well, such as the elderly and people with disabilities, and it is difficult to open or give up if the container lid is tightly closed. Often to do.
[0008]
In addition, small lids with a diameter of around 20 mm, such as recently popular small drinks, are difficult to open even by young people with a small rotational moment. The lid opening tool of the present invention is characterized in that a belt-like body having a thickness of about 1 to 10 mm is wound around the container lid several times, so that the apparent diameter is increased and the moment is increased to facilitate opening. In addition, since one end of the belt-like body is temporarily fixed to the container lid, no slip occurs between the wound belt-like body and the container lid, and the force to rotate the belt-like body is surely applied to the container lid. To be told. At this time, since the belt-like body is wound in the direction to open the container lid, the force of fingers and hands trying to turn in the opening direction by gripping or holding the belt-like body on the outermost circumference of the wrapped belt Works in the direction of tightening the body. Then, when the wound belt-like body is well tightened and there is no play, the force of the finger or hand works to open the container lid. On the other hand, the force of the finger or hand also works to press the wound belt-like body against the container lid and open the lid with the frictional force.
[0009]
The belt-like body of the present invention is made of a flexible and strong material such as rubber, plastic, leather, and fabric. In addition, a material having good sliding properties is preferable. The dimensions are appropriately selected according to the shape and dimensions of the lid to be applied, but generally used are 10 to 50 mm in width, more preferably about 20 to 40 mm, and 1 to 10 mm in thickness. The length is preferably about 2 to 5 mm and the length is about 10 to 100 cm, more preferably about 20 to 50 cm.
[0010]
And the attachment part for temporarily adhering to the side surface of a container lid is provided in the inner surface of the one end part of this belt-like body. The width of the mounting portion is the same as or somewhat narrower than the width of the belt-like body, and the length of the mounting portion is about 1 to 5 cm according to the dimensions of the container lid to be applied. In addition, the attachment portion may be applied with an adhesive, or in the case of a comb or plastic, a part thereof may be subjected to a treatment such as having adhesiveness by chemical change or chemical treatment. Recently, a sheet-like material provided with a large number of micron-order fine suction cups has been provided, but this can also be used as a mounting portion. You may use the sheet | seat provided with many millimeter order suckers. In the case where the adhesive is applied or subjected to an adhesive treatment, there are storage problems such as the adhesive part sticking to the belt-like body or surrounding dust when not in use. In order to prevent this, a protective member may be provided.

DETAILED DESCRIPTION OF THE INVENTION
(Embodiment 1)
Next, the lid opening tool of the present invention will be described more specifically based on the drawings. FIG. 1 is a perspective view showing an example of the lid opening tool 1 of the present invention. The lid opening tool 1 is a belt-like body 2 formed by cutting a flexible polyethylene sheet having a thickness of 3 mm into a width of 30 mm and a length of 50 cm, and is temporarily fixed to the inner surface of one end 2a of the container lid. As the attachment portion 3, an adhesive layer 4 having a thickness of about 2 mm and a length of about 4 cm is provided.
[0012]
The attachment portion 3 may be a member to which a double-sided pressure-sensitive adhesive sheet is adhered, but a sheet base material to which a pressure-sensitive adhesive is firmly applied may be adhered to the belt-like body 2 with a strong adhesive.
[0013]
FIG. 2 is a plan view showing a state in which the lid opening tool 1 is used to open the lid. First, the tip 2a of the belt-like body 2 is pressed against the side surface of the lid 5 of the container to temporarily fix it, and then the belt-like body 2 is wound around the container lid 5. The winding direction is the lid opening direction. In this state, when it is gripped with a finger or hand and rotated in the opening direction, the force F of the five fingers first acts as a force f for fastening the belt-like body 2. Subsequently, when the belt-like body 2 is tightened and no slip occurs, the finger force F acts as a force for rotating the substantially entire side surface of the lid. At this time, since the rotational moment is increased (a → b), the lid can be easily and reliably opened with a weak force.
[0014]
Now, assuming that the thickness of the belt-like body 2 is t, the radius of the container lid 5 is a, and the number of windings is 3, the radius (substantial radius) b with the lid opening device 1 attached is b = a + 3t, The rotational moment increases accordingly.
[0015]
This example relates to a container lid having a small diameter. In this case, it is particularly important that the substantial diameter is increased. On the other hand, in the case of a container lid having a large diameter, the problem of slipping between the opening member and the container lid has a greater influence than the problem of rotational moment. In the case of the lid opening device of the present invention, since one end of the belt-like body is temporarily fixed to the container lid, the problem of slipping between the opening member (belt-like body) and the container lid does not occur. In addition, since the frictional force generated between the hand or finger and the belt-like body is larger than the frictional force between the hand or finger and the container lid, the container having a large diameter is used when the lid opening tool of the present invention is used. In the case of a lid, the lid can be easily opened.
[0016]
(Embodiment 2)
FIG. 3 shows an example of a lid opening device 7 in which a film-like protective member 6 that protects the adhesive layer 4 of the attachment portion 3 is attached to the distal end portion of the belt-like body 2. This protective member 6 covers the adhesive layer 4 when the lid opening tool is not used (chain line in the figure), and causes the adhesive layer 4 to be bare when it is temporarily fixed to the container lid. This protective member 6 prevents dust from adhering to the adhesive layer 4 and sticking to the belt-like body.
[0017]
(Embodiment 3)
FIG. 4 shows an example of another lid opening tool 10 using a suction cup sheet 9 in which a large number of micro suction cups 8 are formed as the attachment portion 3.
[0018]
【The invention's effect】
As described in detail above, the lid opening device of the present invention has a container such as an adhesive layer on the inner surface of one end of a flexible belt-like body having a width of 10 to 50 mm, a thickness of 1 to 10 mm and a length of about 10 to 100 cm. An attachment portion for temporarily adhering to the side surface of the lid is provided.
[0019]
Therefore, the structure is extremely simple, suitable for mass production at low cost, and a lid with a small diameter or a hard lid can be opened easily and easily with a weak force in exactly the same state as a normal opening operation. It is.
