Description

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

  As a prior art of a large synthetic resin bottle-type container with a grip portion, for example, in Patent Document 1, two gripping recesses 8 that can insert a fingertip are formed on both sides of the body portion 3, and both gripping recesses are formed. An invention relating to a grip bottle 1 in which a grip portion constituted by a grip portion 9 provided between 8 is formed integrally is described.

  In this grip bottle 1, the grip bottle 1 is gripped by inserting a thumb into one gripping recess 8 formed in the body portion 3 and inserting another finger into the other gripping recess 8. It can be carried around.

  The invention described in Patent Document 1 adopts a shape in which the bottom wall 82 that constitutes the gripping recess 8 expands toward the outside of the bottle toward the bottom of the bottle, thereby forming the gripping recess 8. This makes it possible to blow-mold the holding recess 8 without using an insert.

JP 2006-8190 A

  However, in the invention described in Patent Document 1, the vertical peripheral walls 84a and 84b constituting the gripping concave portion 8 are greatly expanded in diameter in order to improve the shapeability of the gripping portion 9. For this reason, there is an inclination angle with the straight line K including the vertical peripheral wall 84b with respect to the horizontal axis passing through the central axis O of the bottle 1 (corresponding to the straight line Q in FIG. Therefore, there is a problem that slip is likely to occur between the vertical peripheral wall 84b and the fingertip.

  Further, even when the content liquid is poured out and the remaining amount is reduced, if the grip portion is continuously gripped with a large gripping force, the body portion 3 including the gripping concave portion 8 is easily deformed, and the grip portion is easily held. May decrease.

  Further, the gripping recess 8 is formed without using a movable nest, and since the depth dimension of the gripping recess 8 cannot be formed so deeply, the grip is shallow and the grip portion is easy to hold. There is also a problem that is difficult.

  In order to solve the above-described problems in the prior art, the present invention makes it possible to more stably support the fingertip by improving the ease of gripping at the grip portion by making it easier for the fingertip to get into the grip recess. It is an object of the present invention to create a pinch grip type bottle-shaped container having a gripping concave portion.

Among the means for solving the above problems, the main means of the present invention is as follows.
A gripping recess is formed in each side wall portion of the body of the bottle-type container that is oppositely disposed in the left and right direction, and the back wall portion is positioned behind the gripping recess and the gripping recess in the front-rear direction. In the pinch grip type bottle container that uses the region including
The gripping recess includes a bottom wall that constitutes a depressed bottom surface, a vertical circumferential wall that is disposed opposite to both positions in the front-rear direction across the bottom wall, and a lateral circumferential wall that is disposed opposite to both positions in the vertical direction across the bottom wall. And formed with
It is said that the inclination angle of the vertical peripheral wall with respect to the horizontal axis extending in the front-rear direction passing through the central axis of the bottle-type container is formed at a substantially right angle.

  The inventors of the present application observe the posture in which the user grips the grip portion when the content liquid is poured out in a relatively large pinch grip bottle type container having an internal capacity of 1 liter or more. In particular, depending on the inclination angle of the vertical peripheral wall with respect to the horizontal axis center line, the stability of the hook inserted into the holding concave portion of the finger inserted into the holding concave portion is different, and when the grip portion is strongly gripped The inventors found out that deformation is likely to occur in the side wall portion of the body portion including the holding recess, and have come up with the means of the present invention.

  That is, the inclination angle of the vertical peripheral wall of the holding recess formed in the side wall portion of the trunk portion, more specifically, the inclination angle of the vertical peripheral wall with respect to the horizontal axis center line extending in the front-rear direction through the central axis of the bottle-type container is substantially perpendicular. By using the means to form the above, the degree of hooking (holding function) of the finger with respect to the vertical peripheral wall constituting the concave portion for gripping is improved, and the concave portion for gripping functions as a concave rib having a vertical peripheral wall substantially at right angles By doing so, the rigidity of the side wall portion of the trunk portion including the holding recess is improved.

  According to another aspect of the present invention, in the invention described in claim 1, the deepest part width, which is the opposing dimension between the bottom wall of one gripping recess and the bottom wall of the other gripping recess, is less than 0 mm. It is said to be large and not more than the outer diameter of the neck portion.

  In the above means, a so-called deep grip is achieved by increasing the amount of penetration of the fingertip into the holding recess.

  According to another aspect of the present invention, in the invention described in claim 1 or 2, the flat cross-sectional shape of the back wall portion is a semicircular shape.

  In the above means, the shape of the back wall portion is brought close to the shape of the palm in the gripped state.

Since the present invention has the above-described configuration, the following effects can be obtained.
In the main configuration of the present invention, when the bottle-type container becomes a large-sized blip type bottle of 1 liter or more, if the inclined posture cannot be stably maintained, the outflow rate of the content liquid is not stabilized, thereby further Although the tilting posture may fluctuate, a gripping recess with a vertical peripheral wall formed at a substantially right angle as described above can produce a gripping portion that has a large latching effect and is easy to hold and is easy to compare. Even a user with a small target palm can perform a stable dispensing operation.

  Furthermore, even when the content liquid is poured out and the remaining amount is reduced, the grip portion can be prevented from being deformed even if the grip portion is continuously gripped with a large gripping force. It becomes possible to continue to maintain ease.

  Further, the outermost diameter of the neck portion, wherein the deepest portion width according to claim 2, which is the opposing dimension between the bottom wall of one gripping recess and the bottom wall of the other gripping recess, is larger than 0 mm. In the configuration having dimensions or less, the shape of the grip portion can be made thin and easy to grip, so that a pinch grip type bottle container that is easier to hold than ever can be obtained.

  Further, in the configuration in which the flat cross-sectional shape of the back wall portion according to claim 3 is a semicircular shape, when the grip portion is gripped by hand, the gripped palm and the back wall portion can be fitted. Therefore, it is possible to provide a pinch grip type bottle container that is easier to hold.

It is a front view which shows one Example of the pinch grip type bottle-type container of this invention. It is a side view of FIG. It is a rear view of FIG. It is a plane sectional view in the IV-IV line in FIG.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below along the examples with reference to the drawings.

In the following description, the direction along the front and back of the bottle-type container 1 is the front-rear direction, the direction between both side surfaces is the left-right direction, and the direction between the mouthpiece and the bottom is the up-down direction. And

  This bottle-type container 1 is a biaxially stretched blow molded product made of synthetic resin, has an overall height of 337 mm, a maximum diameter of 126 mm, an internal volume of 2.7 liters, and a bottom portion 8 that exhibits a seat function at the lower end. A cylindrical mouth in which a thread is engraved on the outer peripheral surface through a tapered tubular shoulder 3 and neck ring 2a having a diameter reduced upward at the upper end of the bottomed tubular body 4 provided continuously. It has a structure in which the cylindrical portion 2 is continuously provided.

  The shoulder 3 has a truncated cone shape at the top and a polygonal frustum at the bottom. 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 is provided between 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 deformation of the entire polygonal frustum-shaped portion, that is, the deformation that impairs the appearance, while allowing the deformation of the individual panels 3p during decompression. Demonstrate.

  Side wall portions 5, 5 are arranged opposite to each other on the left and right sides of the body portion 4, and regions recessed from the center of the side wall portions 5, 5 in the front-rear direction are recessed 11, 11. In addition, gripping recesses 12, 12 formed by further recessing the recesses 11, 11 are provided at substantially central portions of the recesses 11, 11.

  At the boundary portion between the shoulder portion 3 and the body portion 4 and at the boundary portion between the body portion 4 and the bottom portion 8, peripheral ribs 7 and 7 that function as a reinforcing peripheral rib are formed. And the label sticking part 4A which can affix a label etc. on the surface of the trunk | drum 4 between the upper peripheral rib 7 and the lower peripheral rib 7 and the front part of the front is provided. (See FIG. 1).

  As shown in FIGS. 2 and 4, the holding recess 12 includes a bottom wall 12 a that forms a depressed bottom surface that is the deepest portion, and a vertical peripheral wall 12 b that is opposed to both positions in the front-rear direction across the bottom wall 12 a. 12b and horizontal peripheral walls 12c and 12c arranged opposite to each other in the vertical direction across the bottom wall 12a. The vertical peripheral walls 12b and the horizontal peripheral walls 12c are provided around the bottom wall 12a. Is formed.

  In FIG. 4, an imaginary line passing through the central axis O of the bottle-type container 1 and extending in the front-rear direction is defined as a horizontal axis center line TCL. At this time, the inclination angle of the vertical peripheral walls 12b, 12b provided at both ends in the front-rear direction, that is, the inclination angle α of the vertical peripheral walls 12b, 12b with respect to the horizontal axis center line TCL is set to be substantially perpendicular. Here, the fact that the inclination angle α is substantially a right angle means that the more preferable inclination angle α is 90 degrees and includes a range of 85 degrees to 95 degrees including manufacturing errors.

Further, the deepest portion width Wd, which is the opposite dimension between the bottom wall 12a of the holding recess 12 formed in one side wall portion 5 in the left-right direction and the bottom wall 12a of the holding recess 12 formed in the other side wall portion 5, is , Larger than 0 mm and not more than the outer diameter dimension φ of the neck portion 2b located at the lower end of the neck ring 2a. In this embodiment, the outer diameter dimension φ of the neck portion 2b is 35 mm and the deepest width Wd is 16 mm, but these dimensions are not limited to this.
The outer diameter dimension φ of the neck portion 2b is an immovable dimension in which the diameter dimension does not change before and after the preform is biaxially stretch blow molded, and the deepest width Wd is the outer diameter dimension φ of the immobile neck portion 2b. Is set as the standard.

  In the present invention, the left and right gripping recesses 12 and 12 and the back wall portion 6 formed between the both gripping recesses 12 and 12 in a semicircular shape with a flat cross section at the rear part of the body portion 4 are provided. The area to include is the grip portion G.

  And as mentioned above, by making the deepest part width Wd below the outer diameter dimension φ of the neck part 2b, the shape of the grip part G can be made thin and easy to grip, and the inside of the gripping recesses 12 and 12 Since it becomes possible to increase the amount of penetration of each fingertip, a deeper grip can be achieved. Therefore, it can be set as the pinch grip type bottle container which is easier to hold than ever.

  The formation of both gripping recesses 12 and 12 as described above is performed simultaneously with biaxial stretch blow molding of the preform. For example, as shown in FIG. 4, the movable nestings 31 and 31 are placed on the horizontal axis center line TCL. On the other hand, it is possible to form by adopting a process of moving in the direction approaching each other from the left and right directions, which are vertical directions, and then moving to the original position.

  In the bottle-shaped container 1 of the present invention, when gripping from the rear and positioning the thumb in one gripping recess 12 and positioning the other finger in the other gripping recess 12 and gripping the grip portion G, The abdomen of the finger comes into contact with the longitudinal peripheral wall 12b located rearward of the gripping recess 12, but the inclination angle α of the longitudinal peripheral walls 12b, 12b with respect to the horizontal axis center line TCL is set to be substantially perpendicular as described above. As a result, slipping between the belly of each finger and the longitudinal peripheral wall 12b is suppressed, and a large latching effect is generated during this time. Therefore, even a user with a relatively small palm can stabilize the pouring operation using the bottle-type container 1.

  Further, the holding recesses 12 and 12 having the vertical peripheral walls 12b and 12b formed at substantially right angles at both ends in the front-rear direction of the bottom wall 12a function as concave ribs against an external force such as a holding force. In addition, the distortion in the side wall portion 5, that is, the occurrence of the depression deformation that impairs the appearance of the side wall portion 5 of the body portion 4 including the gripping concave portion 12 is suppressed.

Further, two reinforcing ribs 13 (see FIG. 2) are provided in the holding recess 12 so as to cross the arch shape (see FIG. 4). The reinforcing rib 13 functions to increase the mechanical strength of the gripping recess 12, and the two reinforcing ribs 13 divide the gripping recess 12 into upper and lower three sections approximately equally. However, with this section, the fingertip of one finger can be stably positioned in any of the sections in the holding recess 12.
The number of reinforcing ribs 13 disposed in the holding recess 12 is not limited to the above embodiment (two), but the size of the bottle-type container 1 or the holding recess 12 may be one or three. The number can be set according to the shape and the like.

  The circumferential length of the grip portion G in the circumferential direction is such that the grip portion G is positioned in a state where the thumb is positioned in one gripping recess 12 and the other finger is positioned in the other gripping recess 12. Since it is necessary to be able to grip, it is set to a substantially constant value in accordance with the average palm size.

  In this bottle-type container 1, the palm fits into the semi-circular back wall portion 6 in the state where the grip part G is gripped, so that the ease of holding the grip part G can be improved. It becomes possible to support stably

  As mentioned above, although the structure of this invention and its effect were demonstrated along the Example, embodiment of this invention is not limited to the said Example.

  The pinch grip type bottle container of the present invention is further developed in the bottle field in which a pinch grip part is formed by forming a concave part for gripping on both side wall parts of the body part to pursue ease of holding as a large bottle container. This can be achieved over a wide area.
