In the case of using the separate package of (a), after removing the lid from the container, the package is opened and poured out, and the additive is injected into the container. May fall into contact with the container placed in the container, causing it to fall down, and it is not always possible to pour the additive from the package into the container. It may be poured out. In addition, the empty package after adding the additive or the package containing the additive becomes garbage, and the in-store environment deteriorates such as leaving or scattering on the table, or contamination of the table due to leakage of the residual additive. The store takes time to clean up the garbage after the customer leaves.
For this reason, the appearance of a lid having a function of holding the package has been long-awaited, and the provision of the above (b) and (c) has been developed. In the case of (b), the lid is first removed from the container. Then, the package is taken out from the lid, and then the package is opened and poured out. Therefore, there is a problem similar to the case (a). Further, in both cases (a) and (b), when shaking to mix the additive contained in the container with the additive after the additive is injected, there is an annoyance that the lid must be attached again.
On the other hand, the lid having the package of (c) integrally, that is, the lid with the package has the advantage that the problems such as the generation of dust and table contamination do not occur, but the conventional lid with the package has the following disadvantages. Due to the complicated shape, there were difficulties in manufacturing and an increase in manufacturing cost. In addition, there are problems that the package cannot be easily opened and the additive cannot be easily poured out, and the contents are spilled due to severe shaking of the container during the opening operation.
[0006]
Forming a bag together with the substrate by joining the periphery of a flexible synthetic resin sheet to the back surface of the substrate, sealing the additive in the bag, and bending the substrate into a V-shape at its longitudinal middle part Since about 1988, various types of folding-rupture-opening-type packages that opened the bag at the same time as breaking the substrate and let the additive in the bag pressed by the substrate pour out from the broken portion have been known. (See Patent Documents 6 to 10). This package has the advantage that no opening device is required and that any amount of additive can be dispensed.

Next, embodiments of the present invention will be described with reference to the drawings.
1 is a perspective view of an example of a lid and a package used by being attached to the lid in the first embodiment, FIG. 2 is a plan view of the lid and the package, and FIG. FIG. 4 is a plan view showing a state in which the body is mounted, and FIG. 4 is a cross-sectional view illustrating an operation when the additive is poured out from the package mounted on the lid. FIG. 5 is a plan view showing another embodiment, FIG. 6 is a plan view showing still another embodiment, and FIG. 7 is a plan view showing a structure of a broadcasting body in still another embodiment.
[0016]
In FIG. 1, a lid A is formed of a transparent or opaque synthetic resin to be thin, and fits into an opening of a container body such as a disposable cup generally used for housing and providing food and drink. And can be sealed. The lid A has a concave portion 3 in which a portion corresponding to the top plate is depressed into an oval shape inside the outer peripheral wall 1 as an example, and is opened on the upper surface surrounded by the inner peripheral wall 2. A cut line (or a weakened line; the same in the present specification) 4 is formed on the bottom plate at a substantially central portion of the lid, and extends along a line perpendicular to the plane where the distance of the inner peripheral wall 2 is reduced. At both ends of the cutting line, it is desirable to provide auxiliary cutting lines 4a connected in a T-shape or a Y-shape in order to facilitate opening of the cutting line 4 described later.
[0017]
A pair of grooves 5 opening upward and in the direction of the concave portion 3 are formed on the surfaces of the inner peripheral wall 2 where the distance between the inner peripheral wall 2 is narrowed and facing each other, at positions opposite to each other with respect to the cutting line 4.
[0018]
The concave portion 3 and the groove 5 can store and hold a foldable breakable package B containing an additive, which will be described later.
Here, the fold-break openable package B will be described with reference to the example illustrated in FIG. 1. The package B has a substantially rectangular substrate 11 having some rigidity and a flexible surface. The periphery of the synthetic resin sheet 12 is joined by bonding or welding to form a bag 13 together with the substrate, and any additives such as sugar, milk, syrup, lemon water, various seasonings, condiments, etc. are contained in the bag. The substrate 11 is filled with a liquid, a granular material, or the like to be added to food and drink. Usually, a break line (or a weak line or a fold line; the same applies hereinafter) 14 is provided at an intermediate position in the longitudinal direction of the other surface of the substrate 11. Are provided, and bags are provided on both sides of an intermediate portion in the longitudinal direction of the substrate 11. Then, by folding the substrate 11 into a V-shape so that the bag 13 is pressed at the middle portion in the longitudinal direction, the substrate 11 is broken at the break line 14 and opened, and the substrate 11 is opened. The additive is pressurized and injected (or ejected) from the broken portion.
[0019]
Reference numeral 15 denotes a support shaft attached to the substrate 11 so as to be mounted on the lid A according to the present invention. In the example shown in FIGS. From the positions opposite to each other with respect to the extension line of a predetermined length.
[0020]
The package B used in the present invention, except for the point that the support shaft 15 is protruded at both ends in the width direction of the substrate 11, the additive is removed from the broken portion of the substrate by bending and opening the substrate and pressing the bag. Any known shape having the structure to be poured and any other configuration may be added.
[0021]
As shown in FIG. 3, the cover A having the above configuration can accommodate the above-mentioned package B in the concave portion 3, and can also hold the support shafts 15 on both sides by fitting them into the grooves 5 on both sides. . In this case, the length of the substrate 11 is large enough to allow a fingertip to be inserted between both ends of the package B held in the longitudinal direction of the substrate and the surface of the lid A that is far away. Is desirably set. Thereby, when the package B is mounted on the cover A with the support shaft 15 inserted into the groove 5, for example, the tip of the thumb and the tip of the index finger are placed between the substrate and the inner peripheral wall of the cover. It can be inserted and locked easily at both ends of the substrate 11. It is preferable that the bottom of the groove 5 is slightly higher than the bottom of the recess 3 because the fingertip on the substrate 11 can be easily applied.
[0022]
While applying force so as to hold the support shaft 15 of the package B in the groove 5, both ends of the board are raised with fingertips locked on both ends of the board, and the board 11 is held as shown in FIG. It can be bent into a V-shape at the break line, and when the ends of the substrate are brought closer to each other, the substrate 11 is broken at the break line and the bag 12 is opened. The additive pressed in the bag by the substrate is jetted or poured downward from the broken portion.
[0023]
When the substrate of the package is broken, the support shafts 15 are provided on opposite sides of the breaking line, so that when the substrate is bent in a V-shape, the broken portion projects downward in a V-shape. The portions that are present on both sides of the cut line 4 of the bottom plate 6 of the lid A are pushed down to open. Therefore, the additive ejected from the bag of the package B is ejected or poured downward from the opening of the bottom plate 6. Therefore, when the lid A is attached to the container body C containing food and drink as shown by a chain line in FIG. 4, it is only necessary to pull up both ends of the substrate of the package B without opening the lid. Additives can be added to food and drink. In order to prevent the support shaft 15 from moving upward in the groove 5 when performing the folding / rupture opening operation of the package, a protrusion that protrudes from one side or both sides of the groove 5 and narrows the groove is provided. It is desirable to prevent the movement of 15.
[0024]
In the above-described embodiment, since the outer shape is a circular lid, a device for reducing the distance of a part of the inner peripheral wall 2 has been devised. However, as illustrated in FIG. 5A, the lid Ae1 has a rectangular shape. In the case of (1), the thickness of the peripheral wall may be made uniform, and a pair of grooves 5 and 5 communicating from the recess 3 to the outside may be formed in the peripheral wall. Also, depending on the type of food and drink, it may be necessary to mount a plurality of packages on one lid. In that case, as shown in FIG. 5B, a plurality of recesses 3 and 3 may be formed in the lid Ae2, and a pair of grooves 5a and 5b; 5a and 5b may be formed on both sides of each recess.
[0025]
In the above-described embodiment, the pair of support shafts 15 of the package B are provided so as to be deviated at positions opposite to each other with respect to the extension line of the break line, but the substrate 11 is bent in a V-shape. In this case, it is only necessary that the tip of the bent portion can push down the top plate (bottom plate 6) of the lid at the position of the cut line to open the lid. As illustrated in FIG. 6, the groove 5c of the lid Ae3 is The bottom plate (bottom plate 6) may be formed so as to have an appropriate width on an extension of the cut line, and a pair of support shafts 15e having an appropriate width may be provided on an extension of the break line of the substrate 11. In that case, the breaking line 14 may be extended to the support shaft 15e. When the substrate is extended in this manner, the substrate can be easily broken at the time of bending. Further, as shown in FIG. 7, when each support shaft is divided and formed (15e ') so as to be appropriately spaced on both sides of the break line 14 of the substrate 11, the cover is cut off at the time of the bending break opening operation. Can be easily and reliably performed.
[0026]
Further, in the above-described embodiment, the cut line that is opened together with the top plate (bottom plate 4) of the lid when the substrate of the package is folded and broken is opened, but instead of the cut line, the cut line is opened in advance. Slits may be provided. In this case, the mounting state of the package to the lid does not need to satisfy the strict condition of opening the cut line of the lid at the time of the folding / rupture opening operation of the substrate of the package.
[0027]
【The invention's effect】
As described above, according to the first aspect of the present invention, the lid is capable of accommodating the folding and breaking openable package, and the support shaft formed in the package is fitted to be rotatable. A groove for holding is provided, and a cut line or an already opened slit is provided at the bottom of the concave portion when the package is folded and broken and opened in a V-shape. The package can be mounted, and the package is formed into a V-shape by performing a folding break opening operation in which both ends of the substrate of the package are pulled up with a fingertip while holding the support shaft of the mounted package in the groove. Then, the additive stored in the package and pressurized is discharged from the opening or slit formed by the cut line of the lid. Therefore, the additive can be injected into the container body to which the lid is attached without removing the lid.
[0028]
According to the second aspect of the present invention, the lid is provided at a position on the peripheral wall opposite to the extension of the cut line or the extension of the center line of the slit. 5. The package according to claim 4, wherein grooves are formed on opposite sides of the lid so as to serve as bearings of spindles provided at positions closest to each other with respect to the breaking line of the substrate. When the package is bent and opened while holding the support shaft of the mounted package in the groove, the package is opened at the breaking line of the substrate. In the case where the lid has a cut line, the bottom plate of the concave portion of the lid is opened at the cut line by the tip of the bent portion. Therefore, there is an advantage that the sealed state is maintained until the package is folded and opened. Further, when the lid has a slit, the distance from the extension of the break line of the projecting position of the support shaft of the package can be reduced, thereby improving the stability of the folding break opening operation. Can be planned. Furthermore, the additive can be injected into the container body simply by folding and opening the package without removing the lid.
[0029]
According to the third aspect of the present invention, the lid is rotatable on a support shaft protruding from the extension of the break line of the substrate of the foldable break openable package on the extension of the slit on the peripheral wall thereof. Since the pair of grooves for holding is formed, the package according to claim 5 can be mounted on the lid, and the package is bent while holding the spindle of the mounted package in the groove. When the rupture opening operation is performed, the package body is bent and rupture-opened at a rupture line of the substrate, and the opened portion is opened toward a slit provided in the bottom plate of the concave portion of the lid. Since this lid supports the support shafts present on both sides of the package in a straight line, there is an advantage that the bending, breaking and opening operation can be stably performed.
