Description

  The present invention relates to a squeeze container.

  Conventionally, a squeeze container as described in Patent Document 1 has been proposed. A squeeze container is a container capable of reducing the volume of the internal space and discharging the contents by pressing and deforming the container. And when the pressure is released, the original shape is restored, so that the container can be repeatedly pressed. The container of Patent Document 1 is provided with a panel in which the width of the pressing portion is narrowed.

JP 2011-105360 A

  By the way, the squeeze container as described above has a problem that since the position where the panel width is pressed is limited and the pressing position is deviated, the force is difficult to act and the container is difficult to deform. Moreover, when it presses forcibly, the wall of a container may be bent and a shape may not be restored | restored. The present invention has been made to solve the above problems, and an object of the present invention is to provide a squeeze container in which the pressing position is not limited and deformation and restoration can be performed smoothly.

  The squeeze container according to the present invention includes an upper part having an opening, a trunk part continuous from the upper part, and a bottom part closing the lower end part of the trunk part, and is surrounded by the upper part, the trunk part, and the bottom part. The body is formed in a cylindrical shape having a rectangular cross section by connecting a pair of opposed first panels and a pair of opposed second panels, and each of the first panels has a circumferential shape. Each of the first panels is formed with a pressing recess extending along the circumferential direction, and each pressing recess is And curved inward in the radial direction along the axial direction, and the connecting portions between the circumferential ends of the pressing recesses and the second panels protrude outward in the radial direction. It is curved to become.

  According to the squeeze container according to the present invention, the volume of the internal space is reduced by pressing the pressing recess, whereby the contents of the container are discharged from the upper opening. Here, since the first panel in which the depression for pressing is formed is curved so as to protrude radially outward along the circumferential direction, it is pushed back when pressure is applied to the inner space side. Repulsive force acts. Therefore, the container whose inner space volume has been reduced by being pressed can be restored to its original shape when the pressing force is removed, and can be pressed again. Since each first panel is formed with a depression for pressing, as described later, the deformation and restoration by pressing the container can be performed more effectively and smoothly.

  In addition, since each pressing recess is curved so as to protrude radially inward along the axial direction, when the pressing recess is pressed, the force is in the direction in which the pressing recess extends in the circumferential direction. Is transmitted to. That is, the pressing force is transmitted to both ends of the squeeze container, and the pressing recess is deformed so that not only the pressed portion but also the whole is pushed toward both ends. Since the pressing recess extends along the circumferential direction of the first panel, the pressing portion is wide, and the pressing force can be transmitted to both ends as described above, regardless of which position is pressed.

  In this way, the force transmitted to both ends of the pressing recess acts to bend the connecting portion with the second panel. At this time, the connecting portion is not a sharp corner, but is curved so as to protrude radially outward, so that the connecting portion is not bent and the apex of the curve moves to the second panel side. And bend to absorb the applied force. Therefore, it is possible to prevent the body portion from being sharply bent by the pressing. As a result, the squeeze container can be smoothly and repeatedly deformed and restored by pressing the container.

  In the squeeze container, each of the pressing recesses can be curved so as to protrude radially outward along the circumferential direction. If it does in this way, it will become easy to concentrate stress when pressing the crevice for press with a finger, and power can be efficiently transmitted to the crevice for press.

  In the squeeze container, the radius of curvature of at least a part of the connecting portion can be 10 to 50 mm, preferably 10 to 30 mm, and more preferably 10 to 20 mm. By making this curvature radius 10 mm or more, it is possible to prevent the connecting portion from being sharply bent. On the other hand, when the thickness is 50 mm or less, the connecting portion is appropriately curved, so that the mechanical strength can be improved.

  In the squeeze container, in order to make it easier to press the pressing recess with a finger, the axial length of the pressing recess is preferably 10 mm or more. Thereby, a finger can be easily fitted into the depression for pressing. On the other hand, by setting it to 40 mm or less, the pressing recess does not become too large, and the force can be transmitted without applying a large force.

  In the said squeeze container, the width | variety of the position corresponding to the said recessed part for a press can be 10-40 mm in a said 2nd panel. Thus, by providing the width | variety of a 2nd panel, the deformation | transformation area | region of a 2nd panel when a 1st panel is pressed can be ensured, and, thereby, the restoration | restoration of a container can be accelerated | stimulated.

  The said squeeze container can make the length of the circumferential direction of the said 1st panel longer than the length of the circumferential direction of the said 2nd panel. Thereby, since the cross-sectional shape of a squeeze container becomes flat shape, it becomes easy to fit two fingers, especially a thumb and an index finger, in each pressing recessed part of each 1st panel, and it becomes easy to press both 1st panels.

  The said squeeze container WHEREIN: The both ends of the said recessed part for a press can be lowered | hung to the said bottom part side in front view. In this way, for example, when the vicinity of the center of the pressing recess is pressed with the thumb, the thumb can be easily placed along the pressing recess. As a result, the container can be easily pressed.

  The “curved” in the present invention means one arc or a shape in which a plurality of arcs are connected. When a plurality of arcs are connected, the radius of curvature is that of the largest arc. means.

  According to the squeeze container according to the present invention, the pressed location is not limited, and deformation and restoration can be performed smoothly.

It is the BB sectional view taken on the line of FIG. It is a front view explaining the usage method of the squeeze container of FIG. It is the partial side view (a) and front view (b) explaining the usage method of the squeeze container of FIG. It is BB sectional drawing explaining the usage method of the squeeze container of FIG.

  Hereinafter, an embodiment of a squeeze container according to the present invention will be described with reference to the drawings. 1 is a front view of the squeeze container, FIG. 2 is a side view of FIG. 1, FIG. 3 is a cross-sectional view taken along line AA in FIG. 1, and FIG. In the following, for convenience of explanation, the vertical direction in FIG. 1 is referred to as the vertical direction or the axial direction, and the horizontal direction is referred to as the width direction or the circumferential direction. A direction from the center (point Z) in FIG. 3 toward the outside is referred to as a radial direction. And it demonstrates also in other drawings on the basis of these.

  As shown in FIGS. 1-4, the squeeze container 1 which concerns on this embodiment accommodates contents, such as a liquid form, a gel-like foodstuff, and a chemical | medical agent. The squeeze container 1 includes an upper portion 11 having an opening, a trunk portion 12 extending continuously downward from the upper portion 11, and a bottom portion 13 closing the lower end portion of the trunk portion 12. S is formed. The upper part 11 has a cylindrical neck part 111 to which a lid (not shown) is attached, and a cylindrical opening is formed at the upper end of the neck part 111. And the external thread 113 is formed in the periphery of this opening, and the lid | cover which closes an opening can be attached detachably. At the lower end of the neck portion 111, a shoulder portion 112 that is gently curved downward in a front view is provided.

  The body 12 is connected to the lower end of the shoulder 112. The body portion 12 is formed in a cylindrical shape, and the lower end portion thereof is closed by the bottom portion 13. As shown in FIG. 3, the body 12 includes a pair of first panels 121 arranged to face each other, a pair of second panels 122 arranged to face each other so as to be orthogonal to the first panels 121, and first adjacent ones. And four connecting portions 123 that connect the panel 121 and the second panel 122. Thus, the body 12 is formed in a cylindrical shape having a substantially rectangular cross section around the axis Z extending in the vertical direction between the upper portion 11 and the bottom portion 13. Further, in this example, the trunk portion 12 has a circumferential length L1 extending along the first panel 121 longer than a circumferential length L2 extending along the second panel 122. It is formed in a flat shape. Note that L1 is preferably longer than L2.

  Next, each part which comprises the trunk | drum 12 mentioned above is demonstrated. As shown in FIG. 3, the first panel 121 is curved so as to protrude radially outward along the circumferential direction. For example, when the width L1 of the first panel is 40 to 90 mm, the curvature radius R1 of the first panel can be set to 50 to 150 mm. By forming such a curve, a repulsive force when pressed as described later can be generated, and thus the shape can be easily restored after deformation. As shown in FIGS. 1, 2, and 4, a pressing recess 1211 for pressing with a finger is formed in the vicinity of the center in the vertical direction of the first panel 121 so as to extend along the circumferential direction. ing. The pressing recess 1211 extends in the width direction up to the vicinity of both ends of the first panel 121. The shape in front view is generally rectangular, but is curved so that the lower side is convex upward, and both ends are lowered to the bottom side in front view.

  The pressing recess 1211 preferably has a central axial length X of 10 to 40 mm. By setting it to 10 mm or more, it is possible to easily fit a finger, and by setting it to 40 mm or less, the pressing recess 1211 does not become too large, and the squeeze container 1 can be deformed without applying a large force during pressing. It becomes. Further, the pressing recess 1211 is curved in the axial direction and the circumferential direction. Specifically, as shown in FIG. 2, the pressing recess 1211 is curved along the axial direction so as to protrude toward the inner space S, that is, radially inward. The radius of curvature R2 of the pressing recess 1211 can be set to, for example, 10 to 60 mm. Moreover, as shown in FIG. 4, it is curving so that it may become convex to radial direction outward in the circumferential direction. The curvature radius R3 can be set to, for example, 50 to 200 mm.

 The radius of curvature R3 of the pressing recess 1211 is preferably larger than the radius of curvature R1 of the first panel, that is, R3> R1. Thereby, as will be described later, the pressing position is wide, and the pressing force can be transmitted to both ends regardless of which position is pressed.

  Furthermore, the connection part 123 which connects the circumferential direction both ends of the recessed part 1211 for a press and the 2nd panel 122 is curving so that it may protrude in radial direction outward, and the curvature radius R4 of the connection part 123 is 10-10. It can be 50 mm, preferably 10 to 30 mm, more preferably 10 to 20 mm. By setting the curvature radius R4 to 10 mm or more, the connecting portion 123 can be prevented from being sharply bent as will be described later. On the other hand, since the connection part 123 curves moderately by setting it as 50 mm or less, mechanical strength can be improved.

  The curvature radius R4 of the connecting portion 123 is preferably smaller than the curvature radius R3 of the pressing recess, that is, R4 <R3. Thereby, as will be described later, the connecting portion 123 is not bent, but can be curved so as to absorb the applied force so that the portion adjacent to the pressing recess 1211 moves to the second panel side. .

  As shown in FIG. 2, the width L2 of the second panel 122 is narrower than that of the first panel 121. However, in the vertical direction, the width of the position corresponding to the pressing recess 1211 is the smallest, The lower region is wider. The width Y of the narrowest portion is preferably 10 to 40 mm in order to ensure deformation when pressed, as will be described later. The second panel 122 is also curved so as to protrude radially outward along the circumferential direction, but has a large radius of curvature and a smaller degree of curvature than the first panel.

  The bottom portion 13 that closes the lower end portion of the body portion 12 is formed in a rectangular shape in plan view, and has a recess 131 whose center is raised upward. And the area | region around the recessed part 131 is comprised so that an installation surface may be touched.

  The squeeze container 1 can be formed of, for example, polyethylene terephthalate, polyethylene, polypropylene, or the like, and a specific gravity of 0.7 to 2.0, preferably 0.8 to 1.8 can be used. . As a manufacturing method, it can manufacture by well-known blow moldings, such as injection blow molding. Moreover, it is preferable that the thickness of such a container 1 shall be 0.2-2 mm, for example, and it is further more preferable to set it as 0.3-1 mm. From the viewpoint of smoothly performing deformation and restoration by pressing the container 1 repeatedly and smoothly, the thickness of the body portion 12 is preferably 0.4 to 0.7 mm, and more preferably 0.45 to 0.6. The inner volume of the container 1 is preferably 100 to 500 mL, for example, as the content capacity. The height of the container 1 is preferably 10 to 20 cm.

  Next, a method of using the squeeze container configured as described above will be described with reference to FIGS. First, as shown in FIG. 5, a thumb and an index finger (not shown) are arranged in the pressing recesses 1211 of each first panel 121, and the squeeze container 1 is sandwiched between both fingers. Next, each pressing recess 1211 is pressed with the thumb and forefinger. At this time, as shown in FIG. 6A, each pressing recess 1211 is curved so as to protrude radially inward along the axial direction, and as shown in FIG. 6B. The force that presses each pressing recess 1211 is also transmitted in the width direction. That is, the pressing force is transmitted to both ends of the squeeze container 1, and the pressing recess 1211 is deformed so that not only the pressed portion but also the whole is pushed toward both ends.

  In this way, the force F transmitted to both ends of the pressing recess 1211 acts to bend the connecting portion 123 with the second panel 122. At this time, the connecting portion 123 is not a sharp corner portion, but is curved so as to protrude outward in the radial direction, so that the connecting portion 123 is not bent as shown in FIG. Is curved so as to absorb the applied force so as to move toward the second panel 122 (from K1 to K2).

  Along with this, the body 12 is deformed so as to be flat, and the volume is reduced. Thereby, the contents are pushed out and discharged from the upper part 11 of the container to the outside through the discharge hole of the lid part. And if the force which presses the recessed part 1211 for a press is loosened, since the deformation | transformation of the trunk | drum 12 will be restored and it will be in an original shape, it will be in the state which can be pressed again so that the contents can be discharged again.

  As described above, according to the present embodiment, since the pressing recess 1211 extends along the circumferential direction of the first panel 121, the pressing portion is wide, and no matter which position is pressed, as described above. Force can be transmitted to both ends. The force transmitted to both ends of the pressing recess 1211 acts to bend the connecting portion with the second panel, but the connecting portion 123 is not a sharp corner, but protrudes radially outward. Therefore, it is curved to absorb the applied force. Therefore, it is possible to prevent the body portion 12 from being sharply bent by the pressing. As a result, the squeeze container 1 can be smoothly and repeatedly deformed and restored by pressing the container.

  As mentioned above, although one Embodiment of this invention was described, this invention is not limited to this, A various change is possible unless it deviates from the meaning. For example, in the said embodiment, although the cross-sectional shape of the trunk | drum 12 is made into flat shape, it can also be made into square shape.

  The shape of the pressing recess 1211 is not particularly limited as long as it extends at least in the width direction to the vicinity of the end of the first panel 121.

  The pressing recess 1211 is curved radially outward along the circumferential direction as described above, but it is sufficient that it is curved at least in the axial direction, and needs to be curved over the entire circumferential direction. There is no. That is, in order to smoothly connect with the connecting portion 123, at least both ends of the pressing recess 1211 need to be curved, but the center portion does not necessarily have to be curved.

  The curved shape of the connecting portion 123 may be not only a single arc but also a plurality of arcs connected, and the curvature radius of at least one of the arcs is 10 to 50 mm, preferably 10 as described above. It is preferable that it is -30 mm, More preferably, it is 10-20 mm.

  As described above, the second panel 122 may not be curved, and may be formed in a flat surface shape.

  In the above embodiment, the upper portion 11 is constituted by the neck portion 111 and the shoulder portion 112, but the configuration of the upper portion 11 is not limited to this, and at least has an opening to which a lid can be attached. That's fine.
