Description

  The present invention relates to a packaging container.

  Patent Literature 1 discloses a packaging container manufactured by filling a cup-shaped container body with contents such as food and closing an upper opening of the container body with a cover member. The cover member has a through-hole for taking out the contents, and a lid portion for opening and closing the through-hole.

JP 2014-061932 A

  By the way, in such a packaging container, the contents are taken out from the through hole by opening the lid and then tilting the packaging container. However, there is a problem that even if the packaging container is tilted, the contents are clogged with each other and the contents cannot be easily taken out. The present invention has been made to solve the above problems, and has as its object to provide a packaging container capable of facilitating removal of contents.

  A packaging container according to the present invention includes a cup-shaped container main body that stores contents, and a cover member that closes an upper opening of the container main body, wherein the container main body has a long axis and a short axis orthogonal to the long axis. And a side wall extending from the periphery of the bottom wall, the pair of first and second surfaces extending in the major axis direction and facing each other, and extending in the minor axis direction and facing each other. A side wall portion having a pair of third and fourth surfaces, wherein at least one of the first surface and the second surface is inclined to be separated from each other as the distance from the bottom wall portion increases, The angle of inclination of the first surface is different from the angle of inclination of the second surface, and the first surface is formed so that a portion near the center in the circumferential direction is convex outward. , A through-hole, and a lid for opening and closing the through-hole so as to be openable and closable. Hole and the lid portion are arranged near the center of the long axis direction.

  According to this configuration, the first surface and the second surface extending in the long axis direction are inclined so as to be separated from each other as the distance from the bottom wall is increased. Therefore, when the packaging container is inclined, the contents are removed. It is easy to guide the cover member side along any of the surfaces. Therefore, the contents can be easily taken out.

  Here, when the inclination angles of the first surface and the second surface are both increased, the balance when the bottom wall portion is installed on a horizontal surface and the packaging container is erected is deteriorated, and the packaging container may easily fall over. There is. On the other hand, it is conceivable that the thickness of the container body is increased to suppress the lowering of the balance, but the cost may be increased. Therefore, in the present invention, the inclination angle of the first surface and the second surface are made different, and the inclination angle of either one of the surfaces is increased, so that the balance at the time of standing can be deteriorated without increasing the wall thickness. It can be prevented and the contents can be easily taken out.

  In addition, since the first surface and the second surface come closer to the bottom wall, the outer shape of the side wall of the container body becomes smaller as it goes to the bottom wall. Therefore, the packaging container can be easily grasped.

  Furthermore, since the inclination angles of the first surface and the second surface are different from each other, it is easy to distinguish these surfaces, and it is possible to prevent the cover member from being erroneously mounted in the wrong direction.

  In the packaging container, the lid can be attached to the second surface side so as to be freely opened and closed by a hinge, and the inclination angle of the first surface can be made larger than the inclination angle of the second surface. .

  According to this configuration, since the hinge is provided on the second surface side, when the lid is opened, the upper end of the packaging container is inclined to the first surface side to take out the contents. At this time, the palm is in contact with the second surface, and the four fingers other than the thumb are in contact with the first surface, so that the user holds the packaging container. Because it is easy to follow, the packaging container can be easily grasped by hand. In addition, since the inclination angle of the first surface is large, the contents can be more easily taken out.

  In the packaging container, the inclination angle of the first surface and the second surface is not particularly limited. For example, the inclination angle of the first surface from a direction perpendicular to the bottom wall is 1.5 to 4 0.5 degree, and the inclination angle of the second surface from the direction extending in the vertical direction can be 0 to 3 degrees.

  According to the packaging container according to the present invention, the contents can be easily taken out.

  Hereinafter, an embodiment of a packaging container according to the present invention will be described with reference to the drawings. Hereinafter, for convenience of description, the description will be made in the directions shown in FIGS. 1 to 4, but the packaging container according to the present invention can be defined without being limited to this direction.

<1. Outline of Packaging Container>
1 is a front view of the packaging container, FIG. 2 is a right side view of FIG. 1, and FIG. 3 is a plan view of FIG. As shown in FIGS. 1 to 3, this packaging container includes a cup-shaped container main body 1 that stores contents such as granular foods, and a cover member 2 that closes an upper opening of the container main body 1. ing. Hereinafter, these members will be described in detail.

<1-1. Container body>
4 is a front view of the container body, FIG. 5 is a sectional view taken along line AA of FIG. 4, FIG. 6 is a sectional view taken along line BB of FIG. 5, FIG. 7 is a plan view of FIG. It is a bottom view. As shown in FIGS. 4 to 8, the container body 1 has an elliptical bottom wall portion 11 and a side wall portion 12 extending upward from the periphery of the bottom wall portion 11, and these are made of a resin material. Are formed integrally. As shown in FIG. 8, the bottom wall portion 11 includes a first side 111 and a second side 112 extending in the longitudinal direction, and a third side 113 and a fourth side 114 extending in the lateral direction, and these are combined. This forms an elliptical outer shape having a major axis and a minor axis orthogonal thereto. The first side 111 is located on the front side, and the second side 112 is located on the rear side. The first side 111 and the second side 112 face each other and are formed in an outwardly convex arc shape. On the other hand, the third side 113 is located on the right side, and the fourth side 114 is located on the left side. The third side 113 and the fourth side 114 face each other and are formed in an outwardly convex arc shape. The short axis is preferably 5 to 30 mm, more preferably 10 to 30 mm, and particularly preferably 15 to 25 mm. On the other hand, the major axis is preferably 20 to 60 mm, more preferably 30 to 50 mm, and particularly preferably 35 to 45 mm. The height of the entire packaging container is, for example, preferably from 50 to 150 mm, more preferably from 55 to 120 mm, and particularly preferably from 70 to 100 mm.

  As shown in FIG. 8, the side wall 12 includes a first surface 121, a second surface 122 extending from the first side 111, the second side 112, the third side 113, and the fourth side 114 of the bottom wall 11, respectively. It has a third surface 123 and a fourth surface 124. Each of the first to fourth surfaces 121 to 124 is curved so as to correspond to the shape of the first to fourth sides 111 to 114 so that the vicinity of the center in the circumferential direction is outwardly convex. However, in the side wall part 12, the connection part 125 with the bottom wall part 11 is formed in an arc-shaped cross section. That is, it is chamfered in an arc shape that is convex outward. Further, a thin portion (upper end portion) 126 having a small thickness is formed over the entire circumference from the upper opening 120 of the side wall portion 12 to a predetermined length downward. The cover member 2 described above is attached to the thin portion 126. In the following, for convenience of description, a portion of the side wall portion 12 below the thin portion 126 may be referred to as a main body portion 127.

  As shown in FIG. 5, the first surface 121 and the second surface 122 of the side wall portion 12 have substantially the same thickness, but the inclination angle of the first surface 121 from the bottom wall portion 11 is larger than that of the second surface 122. Has become. That is, the first surface 121 and the second surface 122 are inclined from the bottom wall portion 11 so as to move away from each other as going upward, but the first surface 121 is inclined more than the second surface 122. I have. For example, the inclination angle α of the first surface 121 from the vertical direction can be 1.5 to 4.5 degrees, and the inclination angle β of the second surface 122 from the vertical direction can be 0 to 3 degrees. The inclination angle α of the surface 121 can be 1.1 to 5 times the inclination angle β of the second surface 122. As an example, the inclination angle α of the first surface 121 can be set to 3 degrees, and the inclination angle β of the second surface 122 can be set to 1.5 degrees.

  Accordingly, the radii of curvature of the first side 111 and the second side of the bottom wall portion 11 are different. For example, the radius of curvature of the first side 111 may be smaller than the radius of curvature of the second side 112. it can. The radius of curvature of the first side 111 can be, for example, 34 to 42 mm (specifically, for example, 39 mm), and the radius of curvature of the second side 112 is 36 to 45 mm (specifically, for example, 41 mm). The radius of curvature of the third side 113 and the fourth side 114 can be the same, for example, can be 4 to 12 mm, and preferably 6.5 to 9.

  Next, the thin portion 126 will be described. As shown in FIG. 4, a groove (engaging portion) 128 extending over the entire circumference in the circumferential direction is formed at an intermediate portion in the vertical direction of the thin portion 126, and the groove 128 is formed in the groove 128. The projections (engaged portions) 225 formed on the front end are fitted. In the thin portion 126, a notch 129 is formed above the groove 128 from the third surface 123 to the first surface 121 and the second surface 122. The notch 129 is formed so as to cut out the entire third surface 123 and further extend slightly to the first surface 121 and the second surface 122. The shape of the portion of the notch 129 corresponding to the first surface 121 and the second surface 122 is symmetric. Therefore, as shown in FIG. 4, when the container main body 1 is viewed from the front side, the rear side of the container main body 1 can be visually recognized through the notch 129. Thus, for example, as shown in FIG. 9, when the laser 5 is irradiated from the front side (one side) of the container body 1 toward the notch 129, the laser 5 does not contact the container body 1 and , And is received by a light receiver 3 arranged on the rear side (the other side) of the container body 1.

  The size of the notch 129 can be determined in consideration of the displacement of the laser 5 to be irradiated. For example, as shown in FIG. 4, when the container body 1 is viewed from the front side in a side view, the length X from the right end of the thin portion 126 is 5 mm or more, and the length Y from the upper end of the container body 1 is 2 mm or more. can do. Thereby, even if the laser 5 is deviated from the target position, it can pass through the notch 129 without fail.

  On the other hand, when the container body 1 is viewed from the front side in a side view, the area of the notch 129 is larger in the thin portion 126 than the groove 128 in order to surely confirm the direction by the laser 5. Is preferably less than 50%, more preferably less than 30%, particularly preferably less than 10%. This is because, for example, if the area of the notch 129 is 50% or more, the laser 5 may pass through the notch 129 even if the direction of the container body 1 is wrong, and the correctness of the orientation can be correctly determined. Because it cannot be done.

  Although not shown, a mark indicating a product, such as a product name and a logo, is formed on the first surface 121 of the container main body 1. Is formed.

<1-2. Cover member>
Next, the cover member 2 will be described with reference to FIGS. 10 and 11. FIG. 10 is a plan view of the cover member in a state where the lid is opened, and FIG. 11 is a cross-sectional view showing a state where the cover member is attached to the container body.

  As shown in FIGS. 1, 3, 10, and 11, the cover member 2 includes a cylindrical peripheral wall portion 21 that covers the thin portion 126 of the container body 1, and a top surface portion 22 that covers an upper portion of the peripheral wall portion 21. , Which are integrally formed of a resin material. When the cover member 2 is attached to the container body 1, as shown in FIG. 11, the peripheral wall portion 21 extends upward from the lower end of the thin portion 126 of the container body 1 and extends slightly above the thin portion 126. It is formed as follows. Further, from the upper end of the peripheral wall portion 21 to the top surface portion 22, it is formed in an arc-shaped cross section so as to protrude outward. When the peripheral wall portion 21 is attached to the thin portion 126 of the container body 1, as shown in FIGS. 1 and 2, the outer surface of the peripheral wall portion 21 and the outer surface of the main body portion 127 of the container body 1 are substantially flush. The thickness of the peripheral wall portion 21 is set such that

  As shown in FIG. 10, the top surface portion 22 is formed in an elliptical shape in plan view so as to correspond to the bottom wall portion 11, and a main body portion 221 having a circular through hole 220 formed in the center; And a rectangular lid 222 attached to the main body 221 so as to open and close the 220. As will be described later, the granular food 6 contained in the container body 1 is discharged from the through hole 220. A rectangular recess 223 in a plan view is formed at the center in the left-right direction of the main body 221, and the above-described through hole 220 is formed in the recess 223. The recess 223 extends from the front end to the rear end of the main body 221, and the lid 222 is attached to the rear end edge of the recess 223 via a hinge 224. The cover 222 is formed in a rectangular shape so as to correspond to the recess 223. When the cover 222 is closed, the cover 222 fits into the recess 223, and the upper surface of the cover 222 and the upper surface of the main body 221 are substantially flush. It is formed to become.

  An annular projection 228 that engages with the inner wall surface of the through hole 220 when the lid 222 is closed is formed on the lower surface of the lid 222, thereby fixing the lid 222 to the main body 221. It has become so. As shown in FIG. 11, a ridge 225 extending in the circumferential direction is formed on the inner wall surface of the main body 221, and the ridge 225 is formed in the groove of the thin portion 126 of the container body 1 as described above. 128, the cover member 2 and the container body 1 are fixed. Further, a rib (projection) 226 extending in the vertical direction is formed at a position corresponding to the notch 129 of the container main body 1 on the inner wall surface of the main body 221, and the cover member 2 is attached to the container main body 1. When this occurs, the rib 226 fits inside the notch 129. At this time, when the direction of the cover member 2 is attached to the container body 1 in a direction opposite to the correct direction, the rib 226 comes into contact with the upper end of the fourth surface 124 of the container body 1 and the cover member 2 2 cannot be pushed into the container body 1.

<2. Manufacturing Method of Packaging Container>
Next, a method of manufacturing the packaging container configured as described above will be described with reference to FIG. First, the container body 1 and the cover member 2 are prepared in advance by injection molding or the like. Next, as shown in FIG. 12, the container main body 1 is disposed in the transfer device 71. A plurality of support portions 72 arranged in a line are arranged in the transport device 71, and these are intermittently moved by the transport device 71. Each support portion 72 is formed with a concave portion 721 having an elliptical shape in plan view so as to fit the lower end portion of the container body 1, and the concave portion 721 is formed so that its longitudinal direction is oriented in the transport direction.

  Then, after the container main body 1 is set in the concave portion 721 of each support portion 72, the laser 5 is irradiated from the front side of the container main body 1 toward the notch 129 at the inspection position (1). At this time, if the laser 5 passes through the notch 129 and is received by the light receiver 3 disposed on the rear side of the container main body 1, it is determined that the container main body 1 is installed in the correct direction. On the other hand, when the laser 5 is irradiated on the container main body 1 and is not received by the light receiver 3, it is determined that the container main body 1 is not installed in the correct direction, and the fact is notified. Thus, the operator stops the transfer device 71 and sets the container body 1 in a correct direction. Thereafter, when the support portion 72 moves to the filling position (2), the granular food is filled from the upper opening 120 of the container body 1.

  When the support portion 72 moves to the mounting position (3) after the food is filled in the container body 1 in this way, the cover member 2 is manually or automatically mounted so as to close the upper opening 120 of the container body 1. At this time, the cover member 2 is arranged such that the hinge 224 is disposed on the second surface 122 side of the container main body 1, but when the orientation is reversed, the cover member 2 is provided by the rib 226 as described above. 2 cannot be pushed into the container main body 1 side, it is possible to recognize that the orientation is not correct. Thus, when the cover member 2 is attached, the packaging container is completed. Thereafter, if necessary, the packaging container can be packaged with a film or the like.

<3. How to use packaging containers>
The packaging container configured as described above is used as follows. First, as shown in FIG. 13, the user holds the packaging container by hand so that the palm contacts the second surface 122, and four fingers other than the thumb contact the first surface 121. open. Subsequently, as shown in FIG. 14, the packaging container is inclined forward, and the food 6 is taken out from the through hole 220. Then, when a desired number of foods 6 are taken out, the lid 222 is pushed with the thumb to close the through hole 220.

<4. Features>
As described above, according to the present embodiment, the following effects can be obtained.
(1) Since the hinge 224 is provided on the second surface 122 side, when the cover 222 is opened, the contents are taken out by inclining the upper end of the packaging container to the front side as described above. At this time, since the palm is in contact with the second surface 122 and the four fingers other than the thumb are in contact with the first surface 121, and the container is grasped, the inclination angle α of the first surface 121 is long. The short ring finger and little finger can be moved along easily, and the container can be held firmly so that the container does not slip from the hand. In addition, when the inclination angle β of the second surface 122 is small, the palm and the container wall fit. Therefore, it becomes easy to support the packaging container by hand. Further, since the inclination angle α of the first surface 121 is large, the contents can be more easily taken out when the packaging container is inclined.

  If the inclination angles of the first surface 121 and the second surface 122 are both increased, the balance when the bottom wall portion 11 is installed on a horizontal surface and the packaging container is erected becomes poor, and the packaging container is likely to fall down. Could be. On the other hand, it is conceivable to increase the wall thickness of the container body 1 to suppress the lowering of the balance, but the cost may be increased. Therefore, in the present embodiment, by reducing the inclination angle of the second surface 122, it is possible to prevent the balance at the time of standing up from being deteriorated without increasing the wall thickness.

  In addition, since the first surface 121 is curved so as to protrude outward in the vicinity of the center in the circumferential direction, a portion of the first surface 121 that protrudes outward is formed to extend in the up-down direction. Therefore, when the packaging container is tilted as shown in FIG. 14, the granular contents 6 head toward the through holes 220 of the cover member 2 while being arranged in a line in the vertical direction near the center of the first surface 121, There is also an advantage that the contents 6 can be easily taken out. In particular, when the contents 6 are formed in an oval (football) type or an oblong (long ellipse) type, the above-described effect is enhanced.

  Furthermore, since the inclination angles of the first surface 121 and the second surface 122 are different, these surfaces can be easily distinguished, and when the cover member 2 is attached, it is possible to prevent the cover member 2 from being attached in the wrong direction.

(2) In the present embodiment, the marks are formed on the first surface 121 by forming irregularities on the molding die. For example, when the irregularities of the molding die become large, when the container body 1 is removed from the molding die. It is necessary to increase the draft angle of. In the present embodiment, by increasing the inclination angle α of the first surface 121 on which the mark is formed, the draft of the first surface 121 is increased, and the mark can be reliably taken out of the mold.

(3) Since the notch 129 is formed from the third surface 123 to the first surface 121 and the second surface 122 of the container body 1, the notch 129 is formed when the container 5 is irradiated with the laser 5 from the front side. The laser 5 can be passed through 129 to the rear side. Then, when the laser 5 is received by the light receiver 3 on the rear side, it can be determined that the container body 1 is installed in the correct direction. Thereby, the correctness of the orientation of the container body 1 can be automatically determined, and the cover member 2 can be accurately attached in the correct direction with respect to the container body 1.

  In addition, the direction of the container main body 1 can be confirmed by visually recognizing the position of the notch 129 without performing inspection using a laser. Therefore, the direction of the container main body 1 can be easily confirmed also by human power. In particular, since the notch 129 is formed at the longitudinal end of the container body 1, the position of the notch 129 can be easily visually recognized. In addition, by forming the notch 129 at the end of the container body 1, for example, when the container body 1 is formed by injection molding or the like, the flow of the resin can be improved and the moldability can be improved. There is also.

  Further, when the cover member 2 is attached to the container body 1, the notch 129 is covered by the peripheral wall portion 21 of the cover member 2, so that the notch 129 can be prevented from being seen from the outside. Thereby, the appearance of the packaging container can be improved.

  Further, since the notch 129 is formed above the groove 128 and does not interfere with the groove 128, the groove 128 and the ridge 225 can be firmly engaged, and as a result, the cover member 2 is attached to the container body 1. It can be firmly fixed.

<5. Modification>
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. The following modifications can be combined as appropriate.

<5-1>
In the above embodiment, the bottom wall portion 11 of the container body 1 is formed in an elliptical shape having a long axis and a short axis, and the shape of the side wall portion 12 is also formed in an elliptical cross section in accordance with this. It is not something to be done. That is, any shape may be used as long as it has a major axis and a minor axis, and has a first surface 121 and a second surface 122 along the major axis direction and having different inclination angles. For example, various cross-sectional shapes such as a rectangular shape and a polygonal shape long in one direction can be adopted. Further, it is not always necessary to provide the thin-walled portion 126, and it is sufficient if the cover member 2 can be attached. Also, the marks need not necessarily be provided on the first surface 121 and the second surface 122.

  In addition, the first surface 121 and the second surface 122 of the container body 1 do not necessarily need to be curved outward, and at least a part of a portion projecting outward has a flat surface with a straight cross section. May be formed. For example, the cross section of the side wall portion 12 including the first surface 121 to the fourth surface 124 can be a polygonal shape such as a hexagonal shape. Further, the shapes of the first surface 121 and the second surface 122 may be different. This is the same for the third surface 123 and the fourth surface 124.

<5-2>
The shape of the cover member 2 is not particularly limited. If the through hole 220 and the lid 222 are near the center in the long axis direction, the lid 222 may be opened and closed by means other than the hinge 224. Further, the shapes of the through hole 220 and the lid 222 may be shapes other than the above-described embodiment. Note that the hinge 224 is preferably provided on the side with a small inclination angle.

<5-3>
Notch 129 is not always necessary and need not be provided.

<5-4>
In the above embodiment, the protrusion 225 of the cover member 2 as the engaged portion of the present invention is fitted in the groove 128 of the container main body 1 as the engaging portion. 1 may have a ridge.
