Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a glass bottle having a shape such that a cap can be easily opened, and more particularly to a glass bottle having a neck portion in a bottle body.

[0002]

2. Description of the Related Art In a glass bottle filled with contents such as jams, the mouth of the bottle is sealed with a cap made of metal or plastic so that the contents will not be spilled from the bottle. This cap is usually constructed so that it can be screwed onto the outer periphery of the mouth portion provided with a threaded portion so that the mouth portion can be sealed at any time even after once opened. Therefore, when opening the cap, it is a usual method to hold the bottle with one hand, hold the cap with the other hand, and twist both hands in opposite directions to open the cap. In such bottles, the conventional bottle body is generally a straight bottle having the same thickness in the upper portion, the central portion and the lower portion of the bottle.

[0003]

However, when opening the cap as described above, particularly when opening the cap for the first time after purchasing the product, the cap is generally tightly closed, and the surface of the bottle is Because it is slippery,
With a straight bottle, it was difficult to apply force and it was difficult to open the cap. Therefore, an object of the present invention is to provide a glass bottle having a bottle shape that is easy to grasp and easy to open the cap.

[0004]

DISCLOSURE OF THE INVENTION The present invention relates to a glass bottle in which a cap is screwed into a mouth portion to seal a bottle body,
A round bottle having a substantially circular horizontal section, a bottle body having a constriction, a full capacity of the bottle of 200 to 1,000 ml, a height of the bottle body of 70 to 200 mm, and a body diameter of 60 to 100.
mm, constriction diameter 48 to 80 mm, outer diameter 50 to
85 mm, the ratio of the diameter of the body to the diameter of the waist is 0.80 to 0.
95, the width of the constricted portion is 15 to 35 mm.

By providing a constricted portion on the bottle body, the fingers of the hand holding the bottle body can fit the constricted portion and firmly grip the body, so that force is required when opening the cap. Easy to put. In addition, it is desirable to provide the concavity and convexity on the constricted portion. This is because the finger becomes more slippery and the force can be applied more stably. The uneven processing includes, for example, forming a carved pattern vertically or obliquely in the width direction of the constricted portion that is shallow so that the hand does not hurt, and performing a satin finish on the bottle surface of the constricted portion. Of course, the method of processing the unevenness is not limited to these, and in short, any method can be used as long as it can be caught on a finger and becomes difficult to slip.

The full capacity of the bottle is 200 to 1,000 ml.
The reason is that for bottles of 199 ml or less, the height of the bottle body is inevitably low, and the bottle body becomes thin, and if a constriction is provided, the surface for labeling the contents becomes very small. Because it is not practical. Also,
This is because the constricted part becomes too thin, which makes it difficult to apply force. On the other hand, for bottles of 1,001 ml or more, the height of the bottle body inevitably increases and the body of the bottle becomes thicker. Therefore, even if a constricted portion is provided, the label sticking surface can be secured, but as described below In relation to the grip width that is easy to put in,
This is because the bottle becomes too thick and it becomes difficult to apply force, which is not preferable.

Next, the reason why the height of the bottle is 70 to 200 mm is that it is too low for a bottle having a height of 69 mm or less, as described above. This is because it is difficult to secure the label side in other places. On the other hand, a bottle with a height of 201 mm or more is too high, so use a spoon or jam knife, especially from the bottom or center of the bottle. It is difficult to scoop out the remaining contents.

Further, the diameter of the constricted portion is 48 to 80 mm because the constricted portion is provided to facilitate grasping and exerting force when opening the cap, so that the constriction of the person and the squeeze width are limited. Due to the relationship, it is limited to a diameter that is easy to grip. The reason for this is that the ergonomically defined width is as long as it is easy for people to put their effort into it. As a basis for ergonomics, Table 1 shows the relationship between grip strength and grip width. This is "Handbook of Numerical and Numerical Formulas" (1992).
It was published in April of the year). The upper table of Table 1 is a numerical representation of the relationship between grip strength and grip width, and the lower graph is a graphical representation of this. The grip strength is expressed as a relative value when the maximum value is 100. According to Table 1, the grip strength is 55 for both men and women.
The maximum value appears when mm. The maximum value was 55 mm
The grip width with 80% or more when the grip strength of 100% was set as 100% was taken as the grip width that makes it easy for a person to put effort. That is, the upper limit of the diameter of the constricted portion is set to 80 mm because the gripping width of 80% or more is the limit value of the grip width for both men and women, and it is difficult to apply force if the diameter is larger than this. On the other hand, the lower limit of the diameter of the waist is set to 48 mm.
Even if the diameter is smaller than this, a gripping force of 80% or more is obtained, but if it is 47 mm or less, it becomes difficult to pass the constricted portion with the contents on the spoon.

[Table 1]

Further, the ratio of the barrel diameter of the bottle to the diameter of the constricted portion is 0.80 to 0.95, because the difference between the diameter of the barrel and the diameter of the constricted portion is more than that, the body and the constricted portion. It is difficult to hold the force because the step is large and it is difficult to grip, and conversely, if the difference is less than this, it is not possible to expect the effect of providing the constricted portion, that is, the effect of easy application of force and easy opening of the cap Because.

Therefore, the reason why the bottle has a body diameter of 60 to 100 mm is that the diameter of the constricted portion is set to a grip width that makes it easy for humans to put effort into it as described above, and the diameter of the constricted portion and the body diameter are This is because the ratio is set to such a value that the effect of the necked portion can be more exerted as described above.

The outer diameter of the mouth is 50 to 85 mm because it is difficult to scoop out the contents with a spoon in a bottle having a smaller diameter than that, which is not practical. On the contrary, in the case of a bottle having a mouth with a larger diameter, the cap cannot be held in the palm of the hand, which makes it difficult to open the cap.

Next, since the width of the constricted part is 15 to 35 mm, the constricted part needs to be provided with a width that allows the fingers to fit therein so that the bottle can be firmly gripped.
It is limited by the relationship with the width of the finger. That is,
This is because the constricted portion provided on the bottle body is usually gripped by the thumb and the index finger, and thus the width needs to be such that the thumb, which is the thickest finger, fits. According to the ergonomic statistics (reference document “Japanese anthropometric data” (issued in October 1997), as shown in Table 2, the average width of the thumb of a Japanese person is 19.1 mm. The width of the constricted part is a numerical value obtained by giving a slight width to the width of the thumb in consideration of the balance with the size of the bottle, securing the label surface, etc. If the constricted part is narrower than this, the fingers This is because it does not fit snugly, so it becomes difficult to apply force, and conversely, if it is wider than this, it does not serve as a constricted part, where the width of the constricted part is as shown in FIG. The distance (H4) between the end points (P points) of the inward R portions (p) on both sides.

[Table 2]

The height of the bottle body is 74 mm or more,
The constriction starts from the position 25 to 45 mm from the end of the mouth toward the bottom, because the bottle with a relatively high bottle body has a space to hold in the bottle body. Since it often has a part, it is easier to apply force by providing a constricted part on the body near the mouth because it is closer to the cap. Also, the height of the bottle body is less than 74 mm, and the constricted portion starts from the position of 30 to 40 mm from the bottom end toward the bottom. Since there is no space to hold the body of the bottle and it is not possible to hold the body firmly, the bottom is often held on the palm of the hand.Therefore, it is better to hold the bottle body with a constriction near the bottom. Because it is easy to open the cap. Here, the height of the bottle body is divided based on 74 mm, as shown in Table 3, according to the above "human body measurement data of Japanese people", from the forefinger to the little finger holding the bottle body. This is because the average value of the width (hand width) of 74.0 mm is 74.0 mm. In this way, if the bottle body is higher than this, it is easier to open the cap by providing a constriction in the body near the mouth because the distance between the hand opening the cap and the hand holding the bottle is closer. On the contrary, if the height is less than this, it is difficult to grip the torso and open the cap.Therefore, providing a constriction near the bottom makes it easier to open the cap. Good. As described above with reference to FIGS. 1 and 2, the height of the bottle body is the height from the bottom of the bottle to the start point of the bottle shoulder (the point where the diameter starts to decrease toward the mouth) (H
5) is said.

[Table 3]

The constricted portion must be provided on either the mouth side or the bottom side of the bottle body. Because
As described above, a label for displaying the product name, raw material, manufacturer, etc. of the contents must be attached to the bottle body, and in order to secure the area, the neck portion must be attached to the bottle body. This is because there are restrictions on the locations where they can be provided. That is, it is not practical to provide the constricted portion near the center of the bottle body, because it is preferable that the label is as large as possible for the advertising effect and sales promotion.

When the height of the bottle body is 74 mm or more,
It was decided that the constricted part would start at a distance of 25 to 45 mm from the end of the mouth, and the distance between the thumb and forefinger of the hand holding the constricted part and the thumb of the hand holding the cap was a little apart. This is because it is easier to apply force, and the distance between the starting point of the constricted portion and the end of the mouth needs to be wider than the width of the thumb. That is, if the distance between the starting point of the necked portion and the end of the mouth is less than the above, it becomes difficult to apply force because the distance between the cap and the necked portion is too narrow. This is because the spacing is too wide and the hands are too far apart to make it difficult to put force.

Further, when the height of the bottle body is less than 74 mm, the constricted portion starts at a distance of 30 to 40 mm from the bottom end, as described above. It often has a bottom instead of the bottom, and if you have a bottle bottom, you will need to support the bottle from below, so it is necessary to provide a constriction so that the belly of five fingers fits in the constriction. is there. Therefore, the distance from the bottom end to the starting point of the constriction is limited around the length from the fingertip to the second joint. According to the above “human body measurement data of Japanese people”, the average value of the length from the fingertip of the middle finger to the second joint (second middle node length of the middle finger) is ergonomically determined as shown in Table 4, male and female, and age. Since each of the other average values is approximately 30 to 40 mm, if the constricted part is set to this value, the belly of the finger of the handle just fits the constricted part, and the cap can be easily opened.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will now be described in detail with reference to the drawings showing the embodiments. FIG. 1 is a side view of a relatively high bottle (high bottle) of a bottle body of the embodiment, and FIG. 2 is a side view of a relatively low bottle (low bottle) of a bottle body of the embodiment. FIG. 4 is an explanatory diagram of how to grip the glass bottle (high bottle) of the embodiment. 5 to 7 are explanatory views of how to grip the glass bottle (low bottle) of the embodiment.

Both bottles of the examples are round bottles, the horizontal cross-section of which is round.

The high bottle of the embodiment shown in FIG. 1 has a full capacity of 583 ml and a height (H1) of the main body of 114 m.
m, the body diameter (D1) is 72 mm, the constricted portion diameter (D2) is 63.5 mm, the outer diameter (D3) is 59.9 mm, the ratio of the body diameter to the constricted portion diameter is 0.88, and the constricted portion Width (H4)
Is 19 mm. Also, the constriction is 28m from the end of the mouth.
It starts from the position of m toward the bottom (H2). This is because the high bottle of this embodiment has a bottle body height (H5) of 89.5 mm, and since the four fingers of the handle can be accommodated as described above, the body may be grasped and the cap may be opened. Since it is considered to be many, a waist is provided in the trunk near the mouth.

The low bottle of the embodiment shown in FIG. 2 has a bottle full capacity of 577 ml and a bottle body height (H1) of 99 m.
m, body diameter (D1) is 78 mm, waist diameter (D2) is 72 mm, outer diameter (D3) is 59.9 mm, body diameter to neck diameter ratio is 0.92, waist width ( H4) is 1
It is 9 mm. Further, the constricted part starts from the position 30 mm from the bottom end toward the bottom (H3). This is because the height (H5) of the bottle body of the low bottle of this embodiment is 7
It is relatively low at 1.5 mm, and there are cases where four fingers cannot fit in the torso part, and because the torso diameter or the diameter of the constricted part is relatively large, it is difficult to apply force when grasping the torso part,
Since it is thought that there are many cases with a bottom, a waist is provided in the body near the bottom.

Further, in both the high bottle and the low bottle of the embodiment, the constricted portion is processed to have an uneven shape. As shown in FIG. 3, the high bottle is engraved with thin engraved patterns of the namelets at equal intervals on the outer periphery of the constricted portion, and as shown in FIGS.
The low bottles have thin vertical carving patterns at equal intervals on the outer circumference of the neck. As a result, it becomes a catch on the finger that holds the constricted portion, and it becomes easier to put more effort on the hand.

With respect to how to hold a bottle, a simple questionnaire was conducted as to whether it is easier to open the cap by holding the body or the bottom. For this, a straight bottle having the same dimensions as the high bottle and the low bottle of the embodiment was used, and one male and one female were used.
We asked 0 people whether it is easier to open the "body" or "bottom" of the high and low bottles. As a result, in the case of high bottles, 16 people chose "body",
Whereas "bottom" was selected by 4 people, in the case of low bottles, "body" was selected by 4 people and "bottom" was selected by 16 people. As a result, a bottle with a relatively high height has a space to hold it in the barrel, so it has a barrel that is relatively low, and if the barrel diameter is large, there is no space to hold it in the barrel and the barrel is thick. It was difficult to hold, so it was confirmed that it had a bottom.

Therefore, a bottle having a space for gripping in the body has a constriction in the body near the mouth, and a bottle having no space for gripping in the body has a constriction in the body near the bottom. By grasping the part, the effect of making it easier to open the cap will be further exerted. Therefore, the high bottle of the embodiment has a constricted portion in the body near the mouth, and the low bottle of the embodiment has a constricted portion in the body near the bottom.

How to grip the bottle of the embodiment is shown in FIGS. As shown in FIG. 3, when the cap of the high bottle of the embodiment is opened, the bottle body is generally gripped so that the thumb and forefinger of the handle fit to the constricted portion. On the other hand, when opening the cap of a low bottle, how to grip the bottle body is the same as how to grip the high bottle described above, by gripping the constricted part with the thumb and forefinger and grasping the bottle body. As a way of gripping by gripping and eventually gripping the ring finger with the ring finger, and as a grip method peculiar to low bottles, put the bottom of the bottle on the palm and fit the belly of five fingers to the neck. There is a way to hold like this. This is shown in FIGS.

Next, a further questionnaire was conducted in order to verify whether the effect of the constricted portion was exhibited and the shape of the bottle of the example was such that the cap could be easily opened. Among the high bottles, low bottles, and high bottles and low bottles of the same size and straight bottles having no constriction,
We asked 50 males and 50 females to try to find out which bottle was the easiest to hold and to put their effort into. The questionnaire is for one person, in order of increasing strength 1
Asked to select 2 bottles, 1st and 2nd.
It was calculated as a point and the second place was 1 point. The results are shown in Table 5.

[Table 5]

As shown in Table 5, the most common answer to this questionnaire is a high bottle having 123 points "neck" and then a low bottle having 99 points "neck". Met. From this, it was confirmed that it is easier to apply force and to open the cap more easily when the bottle is provided with a constricted portion than in the straight bottle.

[0027]

According to the present invention, the bottle body is provided with the constricted portion, and the bottle has a full capacity, the height of the bottle, the body diameter, the diameter of the constricted portion, the width of the constricted portion, and the body diameter. Ergonomically designed to consider the optimal value such as the ratio of the diameter of the constricted part, which makes it easy for a person to grasp and apply force. The number of bottles has decreased and the cap has become a bottle shape that is easy to open.
