The holding part 62 is provided, and the spoon 63 can be attached to the food and drink holding part 62 of the knob 61. Therefore, the cap with reseal function can be resealed if it is put on the mouth portion 65 after eating or drinking food or drink in the container 64, and the spoon 63 is attached to the food and drink holding portion 62 of the knob 61. Thus, the spoon 63 can be stored in a sanitary manner so as not to dissipate. Instead of the spoon 63, it is possible to attach a straw to the food and drink holding part 62 of the knob 61.

  However, the cap with the reseal function in Patent Document 1 can reseal the container 64 and can store the spoon 63 and the straw so as not to dissipate hygienically, but the knob extended from the outer periphery of the cap 60. Since 61 protrudes greatly outward, it is bulky as a whole and there is a possibility that it may become an obstacle during distribution.

  Therefore, the object of the present invention is to allow the container to be resealed after opening, and to store the straw etc. in a sanitary and non-dissipating manner, and it is not bulky and does not become an obstruction factor during distribution. It is to provide a cap with a reseal function.

The present invention has been proposed in order to achieve the above object, and is characterized by having the following configuration.
That is, according to the present invention, the cap body has a top wall and a skirt wall hanging from the periphery of the top wall to seal the mouth of the container, and a straw insertion hole is provided in the vicinity of the periphery of the top wall. Forming a small lid that opens and closes the straw insertion hole via a hinge on the top wall of the cap body, and on the side facing the hinge of the small lid, outward from the periphery of the top surface of the small lid An extending opening / closing knob piece is connected via a bent portion that can be bent downward, and the opening / closing knob piece has a straw holding portion.

  Further, according to the present invention, the straw holding portion includes an opening in which a part of a peripheral edge of the opening / closing knob piece is cut out, and a straw holding hole continuously extending from the opening to the center. A cap with a reseal function is provided in which a line passing through the center of the straw and a center of the holding hole of the straw is substantially parallel to a line where the bent portion is bent.

  According to the invention, the cap body is pasted with a film that can be pierced by a straw, and at least the straw insertion hole and the inside of the container are shut off when the cap body is attached to the mouth of the container. A cap with reseal function is provided.

  Moreover, according to this invention, the cap with a reseal function which provided the inner ring which seals the straw insertion hole of the said cap main body on the inner surface of the said small lid is provided.

  The cap with resealing function of the present invention opens a small lid with an opening / closing knob piece close to the skirt wall of the cap body at the bent portion, bares the straw insertion hole, inserts the straw, and sucks the beverage in the container. Drink. In the case of reseal, the straw is pulled out from the straw insertion hole, the small lid is closed by the opening / closing knob piece, and the straw is held in the straw holding portion. Therefore, the container can be resealed and can be stored in a hygienic and non-dissipating manner, such as a straw, and before the consumer uses the container, the opening and closing knob piece is bent by the bent portion to skirt the container. Since it is close to the wall, there is an effect that it is not bulky and does not become an obstacle to distribution.

  The cap with a reseal function according to the present invention has a straw passing through the center of the opening and the center of the holding hole when the straw is inserted into the holding hole by placing the straw in the opening of the straw holding part. Therefore, when the straw is held in the holding portion after use, the straw can be inserted into and inserted into the holding hole through the opening without any trouble that the bent portion bends. Therefore, in addition to the above effect, there is an effect that the insertion and removal of the straw is extremely easy.

  In addition, the cap with a reseal function of the present invention attaches the cap body to the mouth of the container, so that the seal between the straw insertion hole of the cap body and the inside of the container before piercing by the straw is a film on the lower surface of the straw insertion hole. This can be done by pasting. Therefore, in addition to the effects described above, the film can be sealed with high accuracy before being pierced with a straw, and after filling the container with a beverage, it is only necessary to attach the cap body to the mouth, and separately to the mouth. There is an effect that the process of applying a film for sealing can be omitted.

  In the cap with a reseal function of the present invention, when the straw insertion hole is covered with a small lid, the inner ring of the small lid is fitted into the straw insertion hole, and the straw insertion hole is sealed. Therefore, in addition to the above effect, there is an effect that the seal after the piercing of the film by the straw can be performed with high accuracy. Alternatively, it is possible to seal only with an inner ring instead of sealing with a film.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  FIG. 1 is a side view showing a state where a cap with a reseal function according to an embodiment of the present invention is mounted on a container, FIG. 2 is a longitudinal sectional view of the cap with a reseal function in FIG. 1, and FIG. 3 is a cap with a reseal function in FIG. FIG. 4 is a longitudinal sectional view of FIG. In the drawing, a cap 1 with a reseal function is attached to the mouth 3 of a container 2 in a liquid-tight manner, and has a top wall 4 and a skirt wall 5 that hangs down from the periphery of the top wall 4. The mouth portion 3 is sealed, a straw insertion hole 6 is provided in the vicinity of the periphery of the top wall 4 to form a cap body 7, and the straw insertion hole 6 is opened and closed via a hinge 8 in the top wall 4 of the cap body 7. A small lid 9 is provided, and on the side of the small lid 9 facing the hinge 8, an opening / closing knob piece 10 extending outward from the peripheral edge of the top surface 4 of the small lid 9 can be bent downward. Further, the opening / closing knob piece 10 has a straw holding portion 12.

  The container 2 can be filled with beverages such as milk beverages, coffee beverages, fruit juice beverages, and the cap 3 with the reseal function of the present invention can be liquid-tightly attached to the mouth 3 of the container 2, Although there is no limitation in particular in a shape etc., it is preferably used for a cup type thing. The material is mainly synthetic resin or paper, but is not limited thereto. As will be described later with reference to FIG. 5, it can be arbitrarily selected whether or not the straw 14 is provided in advance on the side wall 13 of the container 2.

  As described above, the cap body 7 is composed of the top wall 4 and the skirt wall 5 depending from the periphery thereof, and is attached to the mouth 3 of the container 2 in a liquid-tight manner. The mounting mechanism includes an inner cylinder 20 concentrically provided on the inner surface of the top wall 4 inside the skirt wall 5, a fitting groove 21 is formed therebetween, and the mouth 3 of the container 2 is formed in the fitting groove 21. Make it liquid-tight by fitting. Further, the straw insertion hole 6 is provided in the vicinity of the peripheral edge of the top wall 4, and the straw insertion hole 6 is liquid-tightly opened and closed by the small lid 9 provided on the top wall 4 via a hinge 8. That is, the inner ring 22 is provided on the inner surface of the small lid 9, and the straw insertion hole 6 is sealed by the inner ring 22.

  Further, when a film 24 that can be stabbed by a straw 14 described later is attached so as to cover the lower surface of the straw insertion hole of the cap body 7 and the cap body 7 is attached to the mouth 3 of the container 2, at least the straw insertion hole 6 and The inside of the container 2 is shut off. Therefore, when the cap body 7 is attached to the mouth 3 of the container 2, the cap 1 with the reseal function has a film 24 that seals between the straw insertion hole 6 of the cap body 7 and the inside of the container 2 before being pierced by the straw 14. It will be possible. Therefore, the sealing of the straw insertion hole 6 before the film 24 is pierced by the straw 14 becomes more accurate, and after the beverage is filled in the container 2 during the manufacturing process, the cap body 7 is attached to the mouth 3 thereof. As a result, the step of attaching the film 24 to the container mouth 3 can be omitted.

  An opening / closing knob piece 10 is provided on the side of the small lid 9 facing the hinge 8, and the opening / closing knob piece 10 extends outward from the peripheral edge of the top surface of the small lid 9. It is connected to the small lid 9 via the portion 11 and can be bent downward by the bent portion 11 so that the opening / closing knob piece 10 can be along the skirt wall 5 of the cap body 7. That is, at the time of physical distribution in a state where the cap 1 with a reseal function is attached to the mouth 3 of the container 2 filled with beverage, the opening / closing knob piece 10 for opening and closing the small lid 9 becomes an obstacle to the physical distribution. must not. Therefore, it is desirable that the outer diameter R1 of the opening / closing knob piece 10 along the skirt wall 5 of the cap body 7 be equal to or smaller than the other maximum outer diameters of the cap 1 with the reseal function and the container 2. As described above, when the outer diameter R1 is equal to or smaller than the other maximum outer diameter, it is possible to prevent an increase in the distribution capacity due to the opening / closing knob piece 10 and to reduce the chance of collision between them, thereby achieving good distribution. It becomes possible.

  The opening / closing knob piece 10 has the straw holding portion 12, which has an opening 30 in which a part of the periphery of the opening / closing knob piece 10 is cut out, and a later-described straw 14 extending continuously from the opening 30 to the center. A line L1 passing through the center of the opening 30 and the center of the holding hole 31 of the straw 14 is substantially parallel to a line L2 where the bent portion 11 is bent. For this reason, when the straw 14 is pushed into the opening 30 of the straw holding part 12 and pushed into the holding hole 31, the line L1 passing through the center of the opening 30 and the center of the holding hole 31 is substantially parallel to the line L2 at which the bent part 11 bends. Therefore, even if the straw 14 is pushed from the opening 30 toward the holding hole 31, the straw 14 can be easily inserted into and removed from the holding hole 31 through the opening 30 without bending the bent portion 11.

  FIG. 5 shows a state in which a straw 14 is provided on the side wall 13 of the container 2 to which the cap 1 with a reseal function is attached. The straw 14 is placed in the packaging bag 32 to maintain a sanitary state, and the packaging bag 32 is attached to the side wall 13 of the container 2, whereby the straw 14 is held in close contact with the side wall 13. Further, the straw 14 contained in the packaging bag 32 should not be an obstructive factor during distribution as described above. Therefore, it is desirable that the outer diameter of the state in which the straw 14 containing the packaging bag 32 is tightly held on the side wall 13 of the container 2 is equal to or smaller than the other maximum outer diameter of the cap 1 with the reseal function and the container 2.

  6 and 7 show a state where the cap 1 with a reseal function is attached to a container 2A having a shape different from that of the container 2 of FIGS. 1 to 5, and the straw 14 is provided on the side wall 40 of the container 2A. That is, the container 2A is provided with a recess 41 on the side wall 40, and the straw 14 is tightly held on the side wall 40 while straddling the recess 41. Since the recess 41 is formed on the side wall 40 of the container 2A over the entire circumference in the circumferential direction, the recess 41 exists over the entire circumference of the side wall 4, and the straw 14 containing the packaging bag 32 is held in close contact with the side wall 40. However, when the straw 14 is removed with fingers, the tip of the fingers enters the recess 41 and the straw 14 can be grasped very easily, and the straw 14 can be easily removed from the side wall 40.

  Since the upper and lower ends of the straw are in close contact with or close to the side wall of the container, the straw does not get in the way when the product is transported. In particular, from the viewpoint of physical distribution, as in the case of FIG. 5, the outer diameter of the state in which the straw 14 containing the packaging bag 32 is tightly held on the side wall 40 of the container 2A is equal to or smaller than the other maximum outer diameter of the container 2A. It is desirable. In addition, this recessed part 41 does not need to exist over the perimeter of the side wall 40 of 2 A of containers. That is, it is sufficient that the concave portion 41 has such a shape that the tip of the finger can enter into the recess 41 to the extent that the straw 14 can be easily grasped with a finger.

Next, with reference to FIG. 5 thru | or 10, the utilization condition of the cap 1 with a reseal function which becomes the said structure is demonstrated.
First, the straw 14 containing the packaging bag 32 that is tightly held on the side wall 13 of the container 2 or the side wall 40 of the container 2A filled with the beverage shown in FIG. Next, the opening / closing knob piece 10 which is close to the skirt wall 5 of the cap body 7 is grasped with fingers, and the small lid 9 is opened to expose the straw insertion hole 6 naked (see FIG. 8). Then, the straw 14 being cut through the packaging bag 32 is taken out, the straw 14 is inserted from the straw insertion hole 6, the film 24 is pierced at the tip, and the straw 14 is inserted into the container 2 or 2A to suck the beverage. Drink (see Figure 9).

  In the case of resealing, the straw 14 is removed from the straw insertion hole 6, the small lid 9 is closed by the opening / closing knob piece 10, and the removed straw 14 is pushed into the opening 30 of the straw holding part 12 toward the holding hole 31. The straw 14 can be easily inserted and held in the holding hole 31 without bending the bent portion 11 (see FIG. 10). Thus, the cap 1 with resealing function can reseal the straw insertion hole 6, the beverage remaining from the container 2 or 2A is not spilled, and the straw 14 and the like can be stored hygienically and not dissipated, In addition, since the opening / closing knob piece 10 can be brought close to the skirt wall 5 of the cap body 7 by the bent portion 11, it does not become bulky and does not hinder the distribution.

  If the beverage remaining in the container 2 or 2A is to be sucked again, the straw 14 inserted and held in the holding hole 31 is inserted, the small lid 9 is opened by the opening / closing knob piece 10, and the straw is inserted. The hole 6 is bare and a straw 14 is inserted, and the straw 14 can be inserted into the container 2 or 2A to suck and drink. If the beverage still remains in the container 2 or 2A, the above reseal case may be repeated.

  Although the first embodiment of the present invention has been described above, it should be understood that the specific configuration is not limited to this, and that changes can be made as appropriate without departing from the scope of the present invention.

  The cap with resealing function of the present invention is not bulky and does not hinder physical distribution when it is desired to reseal containers with leftover beverages and to store hygienic and non-dissipating straws after use. If you want to do so, it has high utility value.
