Description

  The present invention relates to a pinch grip type bottle-shaped container in which a grip function part is integrally formed by forming recesses oppositely on both side wall portions of a body part of a large synthetic resin bottle-type container with a grip function part. .

  As a prior art of a large synthetic resin bottle-type container with a grip function part, for example, Patent Document 1 discloses that both side walls of the body part are different from a bottle-type container having a structure in which a separately formed handle is attached to a container body. A concave portion is formed on the portion so that the fingertip can penetrate substantially to the first joint, and a grip portion composed of both the concave portion and the back wall portion located between the concave portions is integrally formed. A pinch grip bottle-type container is described.

  Then, using this grip portion, as shown in the explanatory view of FIG. 8, the thumb is made to enter one recess 111 formed on the side wall portion of the trunk portion 104 and the other finger is made to enter the other recess 111. The body 104 of the bottle-type container can be gripped so as to sandwich the back wall portion 106.

This type of pinch-grip bottle-type container reduces the manufacturing cost, simplifies the manufacturing process, and saves the consumption of resin material, compared to a bottle-type container configured to attach a separately formed handle to the container body. From the point of view of resource utilization, there are not only many advantages, but there is also an advantage that even if the bottle type container has a size of several liters, the gripping property is stably exhibited.

On the other hand, in general, the pinch grip type bottle container of the kind described above has a large storage capacity, and in the case of a large size of about 4 liters, the weight becomes very large in the state filled with the content liquid. It is necessary to be able to take a stable gripping posture according to each operation situation, such as an operation of tilting and dispensing the content liquid, or an operation of hanging and carrying it by hand.
In particular, there is a demand for a bottle-type container that can maintain the tilted posture more stably in the operation of pouring the content liquid, or that can be poured at a desired speed by finely adjusting the tilt angle.

  Therefore, the present invention provides a pinch grip type bottle-type container having a size of several liters so that the inclined posture can be maintained more stably when the content liquid is poured out, or the inclination angle is finely adjusted at a desired speed. It is a technical problem to create a shape in the vicinity of the grip portion so that the pouring operation can be performed.

Among the means for solving the above technical problems, the main configuration of the present invention is as follows.
A mouth tube portion is erected above the body portion via a tapered tubular shoulder portion whose diameter is reduced upward, and a recess is formed on each side wall portion of the body portion so as to face each other. And in a pinch grip type bottle-shaped container that is a blow molded product made of synthetic resin that forms a grip portion with a back wall portion between both concave portions,
This fingertip fits in the position where the fingertip of the index finger extending diagonally upward contacts the rear peripheral wall of the trunk, which is positioned higher than the recess, from the state where the grip portion is held between the thumb and other fingers. To form a concave locking recess,
It is said.

  The inventors of the present application are observing the posture in which the user grips the grip portion when pouring the content liquid in this kind of pinch grip type bottle type container having a capacity of about 4 liters. The hook of the index finger located at the top of one of the recesses is relatively unstable to the middle finger and ring finger, and the index finger is removed from the recess when pouring the content liquid by tilting the bottle-shaped container, It has been found that if it is extended obliquely upward and applied to the rear wall of the body part, the tilted posture can be stably maintained and the tilt angle can be finely adjusted, and the configuration of the present invention has been invented.

That is, the fingertip is positioned at the position where the fingertip of the index finger extending obliquely upward contacts the rear peripheral wall located above the concave portion of the torso in a gripping manner with the thumb and other fingers. By adopting a configuration of forming a recessed recess to fit into,
By fitting the fingertip into this locking recess, the locking effect is exerted, and the inclination of the bottle-type container can be stably maintained via the tip of the index finger extending obliquely upward, and more It is possible to pour the contents with fine adjustment.

In particular, if the bottle-type container is large enough to be about 4 liters, if the tilted posture cannot be maintained stably, the outflow speed of the liquid contents will not be stabilized, and the tilted posture will further fluctuate. The locking effect of the fingertip of the forefinger by such a locking recess is very effective, and even a person with a relatively small palm can stably perform the dispensing operation.
Furthermore, the tilt angle can be finely adjusted by the fingertip fitted in the locking recess, and the content liquid can be poured out at a desired outflow rate.

  Here, the details of the formation position of the locking recess, the shape such as size and depression depth, the number of formation, etc. are the capacity of the bottle type container (weight at filling), diameter, width of the back wall part, or use of the container This can be determined appropriately in consideration of the embodiment.

  According to another configuration of the present invention, in addition to the main configuration described above, a pair of left and right locking recesses are formed on the rear peripheral wall of the body portion.

  The locking recesses can be formed in one place depending on the use mode of the container. However, it is preferable to form a pair of left and right locking recesses on the rear peripheral wall of the trunk so that it can be held by either the left or right hand.

  Still another configuration of the present invention is such that the center line of the bottom surface of the locking recess is inclined obliquely upward and outward with respect to the left and right center line of the back wall portion, and the inclination angle is in the range of 20 ° to 40 °. It is said.

With the above configuration, by setting the inclination angle of the center line of the bottom surface of the locking recess in the range of 20 ° to 40 °, the grip portion is extended obliquely upward from the state of being gripped by the thumb and other fingers. The fingertip of the index finger can be naturally fit into the locking recess without being noticed by the user.
Here, the inclination angle can be determined in the range of 20 ° to 40 ° in consideration of the capacity of the bottle-type container, the diameter, the width of the back wall portion, and the like.

  Still another configuration of the present invention is such that the formation position in the left-right direction of the locking recess in the rear peripheral wall of the trunk portion is set in the vicinity of the left-right position corresponding to the left and right side edges of the back wall portion.

The above configuration relates to the setting of the formation position of the locking recess, and the formation position in the left and right direction of the locking recess in the rear peripheral wall of the trunk is defined as the vicinity of the left and right positions corresponding to the left and right side edges of the back wall portion. By doing so, the fingertip of the index finger extended obliquely upward from the state in which the grip portion is held between the thumb and other fingers is naturally fit into the locking recess without any user awareness. be able to.
Since the left and right positions that can be determined by the above configuration are only a guide, they are referred to as “near the left and right positions” in the above configuration.

  According to still another configuration of the present invention, a circumferential groove is formed in the peripheral wall at a position directly above the concave portion of the body portion, and a locking concave portion is formed in a height range from directly above the circumferential groove to the boundary with the shoulder portion. It is said.

  The above configuration also relates to the setting of the formation position of the locking recess, but by forming the locking recess in the height range from directly above the circumferential groove to the boundary position with the shoulder, the contact of the fingertip with the circumferential groove is achieved. Since the depression deformation of the peripheral wall of the trunk portion accompanying the contact is suppressed, the fingertip can be fixed in a more stable state by the locking recess.

  Still another configuration of the present invention is a polygonal frustum shape in which a plurality of trapezoidal panels formed in a depressed shape so as to surround the peripheral edge with a stepped portion are arranged in parallel in the circumferential direction. The upper end portion of the locking recess is configured to be positioned immediately below the lower end of the ridge line portion that is formed between the adjacent panels.

When the inside of the bottle-shaped container is in a decompressed state, the trapezoidal panel formed in the depressed state further deforms by sinking and absorbs the volumetric deformation of the bottle-shaped container due to decompression without significantly impairing the appearance. A so-called vacuum absorbing function is exhibited.
Here, the ridge line portion formed by the adjacent panels is a polygonal frustum-shaped portion of the shoulder portion, and ribs that suppress the distorted depression deformation as a whole while allowing the depression deformation of each panel during decompression. By having a configuration in which the upper end portion of the locking recess is located immediately below the lower end of the ridge line portion, the depression deformation of the peripheral wall when the fingertip is brought into contact is more effectively achieved. It becomes possible to suppress.
On the other hand, it is possible to prevent damage to the vacuum absorption function of each panel due to the formation of the locking recess.

  In addition, according to the said structure, although it is necessary to match | combine the formation position of a latching recessed part and the formation position of the ridgeline part 3r, the shape of the polygonal frustum-shaped part of a shoulder part, for example, how many panels are formed, etc. Is determined in consideration of not only the design of the shoulder and the vacuum absorbing function, but also the optimal formation position of the locking recess.

  In the pinch grip type bottle-shaped container having the main configuration of the present invention, the grip portion is gripped by the thumb and another finger in a holding recess formed in the rear peripheral wall positioned higher than the recess of the trunk portion. By fixing the fingertip of the index finger extending obliquely upward, the locking effect of this locking recess is exerted, and the inclination of the bottle-shaped container is inclined via the tip of the index finger extending obliquely upward In addition to being able to maintain the adjustment stably, it is possible to pour the content liquid by finely adjusting the inclination adjustment.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below along the examples with reference to the drawings.
1 to 5 show an embodiment of a pinch grip type bottle-type container according to the present invention. FIG. 1 is a front view, FIG. 2 is a side view, FIG. 3 is a rear view, and FIG. . FIG. 5 is a plan sectional view taken along line AA in FIG.

  This bottle type container 1 is a biaxially stretched blow molded product made of synthetic resin, has an overall height of 395 mm, a maximum diameter of 137 mm, an internal volume of 4 liters, and a bottom 8 that exhibits a seat function at the lower end. A cylindrical mouth tube portion 2 in which a thread is engraved on the outer peripheral surface is connected to the upper end of the provided bottomed tubular body portion 4 through a tapered tubular shoulder portion 3 whose diameter is reduced upward. It has a set structure.

As for the shape of the shoulder part 3, the upper part is a truncated cone shape, and the lower part is a polygonal frustum shape. In the lower polygonal frustum-shaped portion, the panels 3p are formed in parallel with each other in the eight circumferential directions. A ridge line portion 3r remains between the adjacent panels 3p.
When the inside of the bottle-type container 1 is in a reduced pressure state, the individual panel 3p is further deformed and exhibits a reduced pressure absorption function, and the ridgeline portion 3r is affected by external force during pressure reduction or contact with a fingertip or the like. On the other hand, the function as a vertical rib is exhibited, and the function of suppressing the distorted deformation that damages the entire polygonal frustum-shaped part and impairs the appearance while allowing the dented deformation of each panel 3p at the time of decompression. Demonstrate.

  A pair of vertically long recesses 11 are recessed and formed in the body portion 4 at a rear side position slightly above the both side wall portions 5 in an opposed posture. Further, the concave portions 11 are further depressed in the upper regions of both the concave portions 11 so that the vertically elongated small concave portions 12 are opposed to each other.

  In this small concave portion 12, three concave portion reinforcing ribs 13 (see FIG. 2) are provided so as to cross the arch shape (see FIG. 5). The recessed portion reinforcing rib 13 exhibits a function of increasing the mechanical strength of the small recessed portion 12, and the three recessed portion reinforcing ribs 13 divide the inside of the small recessed portion 12 into four sections vertically and approximately equally. And by this division, the fingertip of one finger can be stably positioned in any of the respective sections in the small recess 12.

  Further, on the bottom surface 12b of the small recess 12 of each section of the small recess 12 partitioned by the recess reinforcing rib 13, a small protrusion 15 for enhancing the releasability of the blow molded bottle mold container 1 from the blow mold is provided. Forming.

  Then, between the both concave portions 11 and the concave portions 11, the peripheral wall is slightly depressed in the central axis direction of the body portion 4 to form a vertically long rectangular shape and a flat shape of the back wall portion 6 (FIGS. 2 and 3). 5) (see the white arrow in FIG. 5), the circumferential length of the grip portion G in the circumferential direction is the small recess 12 on the one recess 11 side. Since it is necessary to enable gripping (see FIG. 6) with the thumb positioned and another finger positioned in the small recess 12 of the other recess 11, it is substantially constant according to the average palm size. Set the value to

  Next, a circumferential groove 16 that functions as a circumferential rib is formed in the circumferential wall portion of the body portion 4 at a position directly above the recess 11. Then, a pair of left and right engaging recesses 14 are recessed in a reverse C shape at a symmetrical position in the height range of the rear peripheral wall of the body portion 4 from directly above the circumferential groove 16 to the boundary with the shoulder portion 3. Forming.

As shown in the explanatory view of FIG. 7 (a), the locking recess 14 tilts the index finger as shown in FIG. 7 (b) from a state where the grip portion G is gripped between the thumb and other fingers. It is formed at a position where the fingertip of the index finger just hits in a state where it extends upward.
Here, FIGS. 7A and 7B are diagrams when gripping with the right hand, but when the gripping is performed with the left hand, the fingertip of the index finger hits the locking recess 14 on the left side.

  Then, when the bottle-shaped container 1 is tilted and the content liquid is poured out, the index finger is extended obliquely upward as shown in FIG. 7B, and the fingertip is locked so as to fit into the locking recess 14. The pouring posture can be stably maintained, and the pouring speed can be easily controlled by finely adjusting the inclination angle.

The position where the locking recess 14 is formed takes into consideration the capacity (filling weight) of the bottle-shaped container, the body diameter, the width of the back wall portion 6, and the use mode and the average palm size of the user. In this embodiment, the position where the locking recess 14 is formed is set according to the following criteria.
(1) About a height position, it is set as the height range ranging from just above the circumferential groove 16 to the boundary position with the shoulder part 3.
(2) The formation position in the left-right direction is in the vicinity of the left-right position corresponding to the left and right side edges 6s of the back wall portion 6 (see FIG. 3).
(3) With respect to the forming direction, the center line of the bottom surface of the locking recess 14 is inclined 30 ° obliquely upward and outward with respect to the left and right center line CL of the back wall portion 6. (Refer to the inclination angle TH in FIG. 3)
(4) The upper end portion of the locking concave portion 14 is positioned directly below the lower end of the ridge line portion 3r.

Then, the index finger extended obliquely upward from the state (see FIG. 7 (a)) in which the grip portion G is gripped between the thumb and other fingers by the above (1), (2), and (3). The fingertip can be naturally and naturally fitted into the locking recess 14 without the user being aware of it.
In addition, the rib effect of the circumferential groove 16 and the ridge line portion 3r is exhibited by (1) and (4), the surface rigidity of the circumferential wall in the vicinity of the locking recess 14 is increased, and the circumferential wall is depressed when the fingertip is brought into contact therewith. Can be effectively suppressed.

  Here, although the reference | standard which concerns on the formation position of the above-mentioned latching recessed part 14 of (1)-(4) shows a typical example, this reference | standard is not exact | strict and it is a bottle as mentioned above. The capacity (filling weight) of the mold container, the trunk diameter, the width of the back wall portion 6, and the use mode and the average palm size of the user can be set as appropriate. For example, the inclination angle TH of the locking recess 14 is generally preferably determined in the range of 20 ° to 40 °.

For the reference (4), it is necessary to align the upper end portion of the locking recess 14 and the lower end portion of the ridge line portion 3r. Therefore, the polygonal frustum of the shoulder portion 3 such as how many panels 3p are used. The shape of the shape portion is determined in consideration of the design position of the shoulder portion 3 and the reduced pressure absorption function, and the optimum formation position of the locking recess 14.
In this embodiment, the panel (3p) is set to 8 pieces, and 4 pieces are formed on the left and right sides so that the reference (4) can be realized.

  In the case of this embodiment, the lower edge of the panel 3p has an arc shape, but the upper end portion of the locking recess 14 is arranged so as to fit between the adjacent arc-shaped lower end edges, and is positioned in the vicinity. Thus, the reduced pressure absorption function of the panel 3p is not impaired.

Next, in the bottle-type container 1 of the present embodiment, a large number (five) of reinforcing lateral ribs 22 that are projecting ribs are provided on the back wall portion 6 constituting the grip portion G at regular intervals. No. 22 increases the surface rigidity of the flat back wall portion 6 so that when the grip portion G is gripped with a large force by hand, the back wall portion 6 cannot endure and is curved outwardly of the container 1. The bottle-shaped container 1 cannot be stably held due to deformation, and the spout becomes unstable and difficult to pour. Further, it is possible to reliably prevent problems such as the content liquid unexpectedly popping out due to deformation. it can.
Further, a firm grip feeling can be obtained when the grip portion G is firmly grasped by hand.

As mentioned above, although embodiment and the effect of the pinch grip type bottle-type container of this invention were described along the Example, embodiment of this invention is not limited to the said Example. For example, the capacity of the bottle-type container is not limited to 4 liters, and the formation position of the locking recess 14 is not limited to the criteria (1) to (4) adopted in this embodiment, In consideration of the capacity, diameter, back wall width, or usage of the bottle-shaped container, the fingertip of the index finger that extends obliquely upward from the grip portion G held in a gripping shape with the thumb and other fingers is applied. The contact position can be determined according to the basic configuration requirement.
Further, the number of the locking recesses 14 formed is not limited to a pair of left and right, and the number of the locking recesses 14 can be increased and the index finger can be applied to any one of them.

  As described above, the pinch grip-type bottle-shaped container of the present invention is formed with the locking recess into which the fingertip of the index finger extending obliquely upward fits, so that the bottle-shaped container is inclined particularly when the content liquid is poured out. Can be stably maintained, and the tilt angle can be finely adjusted so that the liquid can be poured stably at a desired speed. As a large bottle-shaped container of about several liters Wide range of usage is expected.
