[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a structure of a small package of liquid, paste, powder, granule, or granular contents of foods and beverages such as seasonings and beverages, cosmetics or drugs. More specifically, even if it contains solid matter that has a large particle size as the contents and is difficult to be discharged from the discharge part formed in the package, it can be operated by pinching with one finger. The present invention relates to a package having a structure that can be easily extracted or discharged without being caught in a discharge port.
[0002]
[Prior art]
Conventionally, various compact packaging bodies that can easily extract the contents by expanding the protrusions by forming protrusion-like discharge means on the lid surface of the package and pinching with a finger to perform one-touch folding have been proposed. ing.
For example, the package described in JP-A-59-103866 and JP-A-61-104973, or the actual application 61-156750 previously invented by the present applicant (Japanese Utility Model Laid-Open No. 63-64665). This is the case for the package.
[0003]
[Problems to be solved by the invention]
However, such a conventional package has a size (particle size is about 2 mm) that makes it difficult to clog a discharge port even in a container having a narrow discharge port, such as a liquid, paste, powder, or granule. If there is no problem, if the content is a mixture of large solids with a particle size of 2 mm or more, such as granular foods such as granular pepper or vegetable cut pieces, This has caught the discharge port and has a problem that the contents cannot be extracted smoothly.
The present invention is intended to provide a package structure that solves such problems.
[0004]
[Means for Solving the Problems]
In order to solve this problem, the present inventor made various prototypes of packaging bodies having projections obtained by expanding the shape of a conventional substantially pyramid-shaped projection serving as a discharge outlet of the packaging body into a similar shape as it is. We observed the ease of folding and the extraction of contents.
As a result, it has been found that if the height of the tip of the projection is increased, the discharge port can theoretically expand, but the bending stress is difficult to be transmitted to the tip of the projection, and the fracture of the projection is incomplete. Become. In addition, when the width of the protrusion on the lid folding line is increased, the lid is not easily bent, and a packaging body can be formed that can smoothly expand and form the discharge port as expected even if the tip end of the protrusion breaks occasionally. I couldn't.
In any case, by simply increasing the height and width of the conventional pyramid-shaped projections, a package that forms a discharge port that allows easy lid folding and smooth extraction of contents including solids is obtained. Recognized that there was no reason.
Therefore, the inventor next left the tip of the upper half of the pyramid-like protrusion that becomes the starting point of breakage when the lid is folded, with the conventional shape that is easy to break, and a package with a changed shape of the lower half of the protrusion. As a result of producing and confirming the effect as described above, it was discovered that a package that can easily bend the lid and that can smoothly form a large discharge port that can be expected was obtained, and the present invention was completed.
[0005]
That is, the packaging body of the present invention is a flexible lid in which a hard material lid that can be bent along a folding line having a protruding discharge means as a fracture region at the center of the surface, and a peripheral edge fixed to the back surface of the lid. In the package body in which two or more pocket portions that lead to the breaking region of the lid are formed with the container body made of a sexual member, the tip of the discharge means has a substantially pyramid shape having ridge lines in four directions, and the folding The lower half of the ridge line on the same line as the curved line is formed in a shape orthogonal to one end of the substantially rectangular parallelepiped protrusion, and on the plane and the vertical plane of the substantially rectangular parallelepiped protrusion on the same line as the folding line. The folding line is formed , and as another configuration, a hard material that can be bent along a folding line having a protruding discharge means as a fracture region at the center of the surface. A lid and a peripheral edge on the back of the lid A packaging body having two or more pocket portions that lead to the breakage area of the lid with a container body made of a fixed flexible member, and a substantially pyramid shape having ridgelines in all directions at the tip of the discharge means; In addition, the fold curve is formed by using the lower half of the ridge line on the same line as the fold curve as a gentler ridge line. At this time, if the width of the projection on the folding curve is set to 1/5 to 1/4 of the length of the folding curve, the discharge port associated with the fracture of the projection can be appropriately widened at the time of folding, and the bending force is small. This is preferable. If the ridge line perpendicular to the folding line of the pyramid-shaped discharge means (projection) is extended from the middle of the ridge line to the one end of the lid as a gentle hem line, the strength of the lid increases and the bending force increases. Is effectively transmitted to the tip of the protrusion, and the discharge port can be easily formed. Further, as the rule of thumb, the smaller the inner angle of the tip of the projection, the easier the fracture opening becomes, but on the other hand, the discharge port becomes narrower as a rule of thumb. Therefore, if the internal angle of the tip is increased in order to obtain a discharge port with a large opening area, the base of the pyramid-shaped protrusion is expanded and the discharge port is widened, but on the other hand, the tip of the protrusion tends to be difficult to break. The apex angle is preferably 60 degrees or less.
[0006]
Next, the effect | action of the package of this invention is demonstrated with the use aspect.
The package of the present invention has a projection-like discharge means on the lid surface having a substantially pyramid shape having ridge lines in all directions, and at least a ridge line that overlaps the folding line is formed as a gentler ridge line from the middle to the lower side. Or a ridge line on the same line (overlapping side) as the folding line is interrupted in the middle, and the lower half part from the interrupted part is formed as a shape in which one side end of a substantially rectangular parallelepiped protrusion is orthogonally applied to the ridge line Therefore, when the package is pinched with a finger and a one-touch folding operation is performed, the expansion area of the protrusion-shaped discharge means to be expanded is several steps wider than the area of the discharge port of the conventional pyramid-shaped protrusion.
In addition, as the shape of the discharge means, the upper half of the protrusion is left with a tip angle of 60 degrees or less in accordance with the conventional shape that is easy to break, that is, the shape of the tip is not different from the conventional one. The bending force required for starting the breakage may be almost the same as that in the prior art, and the protrusion can be smoothly expanded to form a discharge port.
Note that if only the height and width of a conventional pyramid-shaped protrusion are increased in order to expand the discharge port, the angle of the protrusion tip becomes large and the ease of starting breakage is lost.

DETAILED DESCRIPTION OF THE INVENTION
The present invention will be described below with reference to embodiments shown in the drawings.
1 and 4 show perspective views of one embodiment and other embodiments of the packaging body 1 according to the present invention, FIG. 2 is an enlarged perspective view of the main part of FIG. 1, and FIG. 3 is the packaging body of FIG. It is a perspective view which shows the expansion state of 1 discharge means. 5 is an enlarged perspective view of a main part of FIG. 4, FIG. 6 is a perspective view of a conventional packaging body 1 ′, and FIG. 7 is a perspective view showing an expanded state of the discharge means 3 of the packaging body of FIG. It is.
1 to 3, reference numeral 1 denotes an embodiment of the package of the present invention that contains a liquid, paste, powder, granule, or granular fluid material as contents, and the lid 2 is made of polystyrene or It consists of a hard sheet of length x width (50 mm x 80 mm) and thickness 300 μm made of a polystyrene copolymer, and a protrusion 3 as a protruding discharge means is provided at the center of the surface of the lid 2. Yes. The protrusion 3 has a substantially pyramid shape with a tip angle of 60 degrees or less, and is provided so as to intersect with a folding line 8 provided on a central axis (not shown) on the lid 2. When bent, the rupture is caused from the tip 7 of the protrusion 3.
Further, the ridge line on the side of the substantially pyramid-shaped protrusion 3 that overlaps the folding line 8 is interrupted (interrupted) in the middle thereof, and the one end of the substantially rectangular parallelepiped-shaped protrusion 9 extends from the interrupted portion to the lower half. The shape is orthogonal to the ridgeline.
Therefore, as shown in FIG. 3, when the lid 2 of the package 1 is folded so that the pocket portions 6 and 6 are close to each other, the tip portion 7 of the projection 3 is broken and the projection 3 and the rectangular parallelepiped shape along the ridgeline. The protrusions 9 are also sequentially broken to form a discharge port that is wider than the discharge port of the conventional discharge means in an expanded state.
At this time, the shape of the tip portion 7 of the projection 3 is not different from the conventional pyramid shape, and the tip angle is set to 60 degrees or less, so that the projection 3 is easily started to break by bending the lid 2, The subsequent fracture area can be expanded smoothly. A plurality of strips 4, 4, 4,... Are provided on the surface of the lid 2 in a direction orthogonal to the folding line 8 so that the back surface of the lid 2 is recessed, and is perpendicular to the folding line 8 of the projection 3. The ridgeline in the direction is formed by extending the back surface of the lid 2 so as to extend into the strip, so that even if the lid 2 is bent, the lid 2 can withstand the bending stress and is not easily distorted. This is so that the stress is sufficiently transmitted.
The back side of the lid 2 is fixed to the periphery of the opening of the container body 5 made of a flexible member, which is formed of a thin layer sheet such as polyethylene or aluminum.
The container body 5 has pocket portions 6 and 6 so that the contents can be filled therein. In the present embodiment, the package 1 has the above-described configuration, and when extracting the contents stored in the pocket portions 6 and 6, the lid 2 is sandwiched between fingers and the pointed end portion 7 of the lid 2 is directed downward. When the lid 2 is folded along the folding line 8 so that the right and left pocket portions 6 and 6 are close to each other, both the pocket portions 6 and 6 are pressed and a large pressure is applied to the contents in the direction of the pointed portion 7 of the lid 2. At the same time, the lid 2 is broken from the pointed portion 7, and the projection 3 and the projection 9 provided on the lid 2 are also sequentially broken and expanded to form a discharge port 10 having a large area. The discharge port 10 whose breakage is widened can be easily extracted even if it is a content containing large solid particles having a particle size exceeding 2 mm.
4 to 5 show a package 1 in another embodiment of the present invention. The same portions and the portions having the same action are given the same reference numerals and their perspective views. It is a principal part enlarged view. The package 1 in FIG. 4 is formed by forming the ridge line on the side overlapping the folding line 8 of the pyramidal protrusion 3 as a gradual ridge line from the middle. That is, there is substantially no difference except that the shape of the lower half of the protrusion 3 is different from that in FIG.
[0008]
Therefore, the sharp end 7 of the projection 3 is first broken by bending the lid 2, and then the ridgeline of the projection 3 and the gentle ridgeline connected thereto are sequentially broken to form a discharge port (not shown) that is expanded to a large area. Is. Since the operation and the like at this time are almost the same as those of the previous embodiment, a duplicate description is omitted.
As described above in the embodiment, the package of the present invention can be used to form a further enlarged discharge port when the contents are extracted, and the pointed shape of the protrusion is a conventional product. Therefore, even when a bending stress is applied when the lid is bent, the tip of the protrusion can be easily broken and the discharge port can be widened without any particular difficulty. 6 and 7 are perspective views showing a state in which a conventional packaging body 1 'formed with a pyramidal protrusion 3 and a narrow discharge port 10 having a substantially triangular shape are formed by bending the same.
[0009]
【The invention's effect】
Since the package of the present invention is shaped so that the shape of the protruding discharge means on the lid surface can be expanded as a wide discharge port when the lid is folded, the discharge port can be used even if the content contains solid matter having a large particle size. Smooth extraction without clogging.
Therefore, the contents can be filled with a variety of contents, and the application can be further broadened.
