【Example】

 Hereinafter, an embodiment of a cap with a housing according to the present invention will be described with reference to the drawings.

In FIG. 1, reference numeral 10 denotes a cap with a housing portion, which can be attached to a mouth 22 of a container 20 described later to close the mouth opening of the container 20.

The accommodating portion cap 10 is formed of a lid having a hat-shaped cross section, and an upwardly projecting portion 12 is provided at the center of a step wall 11 having a substantially horizontal plane and the entire step wall 11 is covered. A flange 13 is provided so as to project downward on the peripheral edge.

The projecting portion 12 has an opening 14 b on the inner surface side of the cap 10 with a housing portion, which projects into the flange 13 and opens downward by a peripheral wall 14 a projecting below the step wall 11. The recess 14 is formed.

The peripheral wall 14 a is formed so that the amount of protrusion from the step wall 11 is smaller than the distance between the upper surface 24 a of the top wall 24 and the upper end 22 a of the mouth 22 described later.

The recess 14 can be sealed by closing the opening 14 b with a shrink film 15.

The recess 14 functions as an accommodating portion, and a seasoning, a medicine, a sports drink, a detergent, or the like, which is made of powder or granules P as a solute that melts in a liquid such as water as a solvent, Be accommodated. The contained material may be a liquid that does not melt or break the shrink film 15.

The flange 13 has a ridge 16 that engages with the ridge 23 of the mouth portion 22 on the inner surface side, and functions as a container mounting portion for tightening and mounting the container-equipped cap 10 on the container 20. To do.

The shrink film 15 can be shrunk by heating, and by pre-forming, the shrink film 15 is slightly expanded in diameter from the opening 14a and formed into a dish shape with a raised peripheral edge.

The shrink film 15 is attached to the peripheral wall 14a by covering the opening 14b after accommodating the contents in the recess 14, and after mounting, shrinking by heating and fixing the shrink film 15 to seal the opening 14b. can do.

The shrink film 15 is formed of a biaxially stretched polyethylene terephthalate film having a thickness of about 30 to 50 μm, or a film of aluminum vapor-deposited on biaxially stretched polyethylene terephthalate. The higher the draw ratio, the better.

Then, the contents are filled in the recess 14 and the opening 14 b is closed by the shrink film 15, so that the seasoning, medicine and the like are hermetically housed in the housing unit cap 10.

As shown in FIG. 2, the container 20 has a mouth portion 22 that forms an opening (mouth portion opening) in which the upper portion of the container body 21 is narrowed and reduced in diameter. The container can be contained in the main body 21 or the contents can be taken out from the main body 21.

The mouth portion 22 has a ridge 23 on the outer peripheral portion thereof, and the ridge 16 of the flange 13 is engaged with the ridge 23 to mount the cap 10 with a housing portion on the mouth portion 22. You can A top wall 24 that closes the mouth 22 is formed inside the mouth 22 substantially parallel to the upper end 22a.

A protrusion 25 having a tip 25 a reaching the upper end 22 a is formed substantially in the center of the top wall 24, and two through holes 26 penetrating the front and back surfaces of the top wall 24 are formed around the protrusion 25. Has been formed.

Therefore, when the cap 10 with a housing portion is attached to the container 20, the shrink film 15 is removed so that the opening 14 b communicates with the mouth opening of the container 20 and the container body is provided with the through hole 26. By connecting the cap 10 with the accommodating portion to the mouth 22 of the container 20 by bringing the upper end 22a into contact with the inner surface of the step wall 11, the shrink film 15 faces the top wall 24. It will be broken by the protrusion 25.

The protrusion 25 functions as a film opening means for breaking the shrink film 15.

The cap 10 with a housing part may be attached to the container 20 by screwing with a screw, fitting with a fitting means such as a protrusion, or the like. Any container can be used as long as it has a mouth portion that can be tightened and attached via the ridges 16 regardless of the shape and size of the container body.

Next, the operation of the cap with a housing having the above structure will be described.

First, as shown in FIG. 3, the container-equipped cap 10 is attached to the container 20 in which the liquid L is filled in the container body 21.

When the mounted cap 10 with the accommodating portion is mounted and the inner surface of the step wall 11 is brought close to the upper end 22 a and the tips 25 a of the projections 25 come into contact with the shrink film 15, the shrink film 15 is perforated.

At the same time when the hole is opened, the shrink film 15 in the contracted and tensioned state is cracked and broken all over the area.

When the shrink film 15 is broken, the opening 14 b opens and the contents contained in the recess 14 fall into the container body 21.

Then, the contained substance that is a solute is easily dissolved in the liquid L that is a solvent, and a mixed liquid in which the contained substance is dissolved in the liquid L is formed in the container body 21.

As described above, by using the shrink film 15 as the film that closes the opening 14b, the container 20 for the contents at the time of opening is compared with the case where another film is used or the opening method such as half-cutting. Moving in is done more smoothly.

In other words, the shrink film 15 is severely torn and opened by just piercing the tip 25a a little, so that the contents in the recess 14 can be reliably and simultaneously moved into the container 20.

Further, FIG. 4 shows another example of the cap with a containing portion.

The accommodating portion cap 30 is formed in a cup shape having an upper wall 30a and an outer peripheral wall 30b, and is opened by an inner peripheral wall 30c projecting parallel to the outer peripheral wall 30b on the back surface of the upper wall 30a. The recess 14 is provided as a housing portion having the portion 31a. The opening 31 a is closed by the shrink film 15.

The outer peripheral wall 30 b has a ridge 32 that engages with the ridge 23 of the mouth portion 22 on the inner surface thereof, and serves as a container mounting portion for tightening and mounting the cap 30 with a housing portion on the container 20. And function (see (a)). Other configurations and operations are similar to those of the cap 10 with a containing portion.

The cap 33 with the accommodating portion does not form the peripheral wall 14 a of the cap 10 with the accommodating portion, but forms the recess 14 as the accommodating portion only by the projecting portion 12 and closes the opening 14 b with the film 15. (See (b)). Other configurations and operations are the same as those of the cap 10 with the accommodating portion.

By the way, in the above embodiment, the projection 25 as the film opening means for breaking the shrink film 15 is formed on the container 20, but a film opening means may be provided in addition to the container 20.

By providing the film opening means separately, the shrink film 15 can be broken even in a container having no film opening means.

FIG. 5 shows the adapter 34 attached to the mouth portion 22.

The adapter 34 is formed in a cylindrical shape having an upper opening 34b and a lower opening 34c together with the peripheral wall 34a, and is attached to the mouth portion 22 by engaging a groove portion 39 described later with the protrusion 23.

The partition wall 35 that closes the inside of the adapter 34 is formed substantially parallel to the upper end of the peripheral wall 34a, and the partition wall 35 is provided with a projection 36 having a tip 36a directed upward at substantially the center. At the same time, two through holes 37 are formed around the protrusion 36 to penetrate the front and back surfaces of the partition wall 35.

A protrusion 38 that engages with the protrusion 13 of the cap 10 with a housing portion is formed on an upper portion of the outer surface of the peripheral wall 34 a, and a groove portion 39 that engages with the protrusion 23 is formed on a lower portion of the inner surface. Has been.

Therefore, the cap 10 with the accommodating portion can be attached to the container 20 via the adapter 34 attached to the mouth portion 22, and when the cap 10 with the accommodating portion is attached to the container 20, the shrink film 15 is broken by the protrusion 36. As a result, the opening 14b is opened, and the accommodation portion 14 and the inside of the container body 21 communicate with each other through the through hole 37 (see (a)).

Further, the adapter 40 has a peripheral wall 41a and a bottom portion 41b, and is formed in a cup shape having an outer diameter smaller than the inner diameter of the mouth portion 22 of the container body 21, and can be inserted into the mouth portion 22. it can.

A flange 42 is formed around the upper opening 41c at the upper end of the peripheral wall 41a. By bringing the flange 42 into contact with the upper end of the mouth portion 22, the adapter 40 is inserted in the mouth portion 22. Retained.

The bottom portion 41 b has the same structure as the partition wall 35 of the adapter 34, and has a protrusion 43 and a through hole 44 corresponding to the protrusion 36 and the through hole 37.

In addition, the adapter 40 has the same configuration and operation as the adapter 34, and when the adapter 40 is attached to the container body 21, the height of the entire container 20 is not increased ( (See (b)).

The cap 10 with the housing portion and the adapters 34, 40 may be attached to the container 20 by screwing with a screw or fitting using a fitting means such as a protrusion.

Further, the cap 10 with the accommodating portion can be used regardless of the shape and size of the container main body as long as it is a container having a mouth part that can be tightened and attached via the adapters 34 and 40. can do.

Further, as an example in which the film opening means is provided in addition to the container 20, the cap with the accommodating portion may be provided with the film opening means.

The cap 50 with an accommodating portion shown in FIG. 6A is a hinge type cap in which a lid body is provided on the cap body via a hinge portion, and is a body that can be attached to the mouth of a container (not shown). It has a (cap body) 51 and an accommodating portion 52 composed of a lid body connected to the body 51 via a hinge 57 described later.

Here, the main body 51 has the same function as the flange 13, and the container has the same configuration as the container 20 except that the top wall 24 is not formed. The main body 51 is formed in a cylindrical shape in which the upper end 51a and the lower end 51b communicate with each other, and has a ridge 53 that engages with a ridge at the mouth of the container at the lower portion on the inner surface side. The main body 51 functions as a container mounting portion for tightening and mounting the cap 50 with a storage portion on a container. Further, a top wall 54 that closes an opening is formed in the upper portion of the main body 51 in substantially parallel to the upper end 51a. The top wall 54 has a projection 55 having a height at which the tip 55a projects from the upper end 51a and a blade 55b protruding in a cross shape in four directions when viewed from above. In addition, two through holes 56 penetrating the front and back surfaces of the top wall 54 are formed around the protrusion 55.

The accommodation portion 52 is connected to the upper end 51 a via a hinge 57 so as to be rotatable upward.

The housing portion 52 is formed in a cup shape having an opening 52 a that opens toward the top wall 54 at the upper end, and can be sealed by closing the opening 52 a with a shrink film 58.

The accommodating portion 52 and the shrink film 58 have the same functions as the recess 14 and the shrink film 15 in the above embodiment.

Therefore, the cap 50 with the accommodating portion is accommodated by closing the hinge 57, rotating the accommodating portion 52 upward, and bringing the end portion on the opening 52a side into contact with the upper end 51a of the main body 51. The part 52 and the main body 51 can be integrated.

When the end on the opening 52 a side is brought into contact with the upper end 51 a, the shrink film 58 is broken by the tip 55 a of the protrusion 55. The protrusion 55 functions as a film opening means for breaking the shrunk film 58.

Then, by removing the shrink film 58, the opening 52a can be communicated with the opening of the main body 51, and is communicated with the inside of the container main body 21 through the through hole 56.

Further, as another embodiment of the cap with a housing portion, as shown in FIG. 6B, a step 61 having an enlarged inner diameter is formed on the upper end 51a of the main body 51, and the opening of the housing portion 52 is formed. A step 62 corresponding to the step 61 may be formed on the outer peripheral edge of the portion 52a, and the cap 60 with the accommodating portion may have the same structure as the cap 50 with the accommodating portion other than the above.

The cap 60 with the accommodating portion is accommodated when the hinge 57 is closed by the steps 61 and 62 and the accommodating portion 52 is rotated upward to bring the opening 52a into contact with the upper end 51a of the main body 51. When the opening 52 a is brought into contact with the upper end 51 a and the shrink film 58 is broken by the projection 55, the contents inside the housing 52 are separated from the main body 51 when the portion 52 is fitted to the main body 51. Can prevent spillage.

The operation of the caps 50 and 60 with the accommodating portion is similar to that in the cap 10 with the accommodating portion.

The shrink film 58 is not necessarily limited to the shrink film, and various films can be selected, but a film obtained by laminating an aluminum foil on a polyethylene film or a polyethylene film is also preferable.

Therefore, since it is not necessary to separately prepare a member for opening in the caps 50 and 60 with the accommodating portion, the structure of the container in which the cap with the accommodating portion is mounted can be simplified, and the hinge portion serves as a fulcrum. As a result, the accommodating portion can be opened by simply closing the lid.

Further, FIG. 7 shows another example of the container in which the cap with the containing portion can be used.

The container 70 has two opening portions 72 that are openings in the upper portion of the container body 71, and the opening portion 72 of the same shape is projected (see (a)), or different. It is a so-called two-necked bottle such as one in which the mouth portions 72 and 73 having a curved shape are provided to project (see (b)).

In this container 70, a trigger 74 for ejecting the liquid in the container body 71 can be attached to one mouth portion 72 (mouth portion 73), and the other mouth portion 72 has a housing portion. The cap 10 can be attached. Other configurations and operations are similar to those of the container 20.

Then, the contained material is moved into the container main body 71 from the other mouth 72 to which the cap 10 with the accommodating portion is attached to form a mixed liquid in which the liquid in the container main body 71 and the contained material are mixed. Then, the mixed liquid can be ejected by the trigger 74 (see (b)).

For this reason, the caps 10, 30, 33, 50, 60 with accommodating portions according to the present invention are particularly useful for refill containers.

Then, for example, when the non-refillable container is filled with a mixed liquid which can be formed by a solvent liquid, the used container is filled with the solvent, and this time, the mixture is mixed. The soot such as powder forming a liquid is filled in the recess 14 (accommodation part 52) and the cap 10 with a storage part 10, 30, 33, 50, 60 (refill cap) is attached, and the powder in the recess 14 is attached. A mixed liquid can be formed by mixing the body and the liquid in the container body.

In addition, in the case of a mixed solution in which the mixed solute is likely to precipitate and cannot be easily mixed when it is precipitated, for example, when heat or the like is not added, the caps 10, 30, 33, 50, 60 with accommodating parts Precipitation can be prevented by containing the solute and mixing it with the solvent immediately before use.

Further, in the case of a mixed solution which cannot be changed over time and needs to be mixed at the time of use, the solute is contained in the caps 10, 30, 33, 50, 60 with the accommodating portion until just before use, and the solute is not used. The effect of changes over time can be avoided by mixing with.

The films of the caps with the accommodating portions and the film opening means of the containers and the adapter are the film opening means when the caps with the accommodating portions are attached to the containers and the adapters, respectively. It is formed in a shape with a position and height that can be broken by. Further, the film opening means in each embodiment is not limited to the protrusions 25 and 36, and may be the protrusion 55.

As described above, since the caps 10, 30, 33, 50, 60 with the accommodating portions can be used as refill products which are replenishment products with the contents refilled, the containers can be reused. Therefore, it can greatly contribute to resource saving.

[0081]

[Effect of the device]

 According to the cap with the accommodating portion according to the present invention, when used, the accommodating portion can be sufficiently opened with a slight force to reliably move the contained object from the accommodating portion into the container.

In addition, according to the cap with the accommodating portion in which the lid is provided via the hinge portion, since the film opening means is integrally provided with the cap with the accommodating portion, it is not necessary to separately prepare the film opening means. In addition to the ease of assembling at the time of use, the housing section can be opened by simply closing the lid with the hinge section as a fulcrum.
