DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cap with a display device, and more particularly to a cap having a display device mounted on a top surface, which can strongly hold the display device before opening. The present invention relates to a cap with a display device, which can be easily separated after opening, and can be easily assembled and mounted.

[0002]

2. Description of the Related Art As a method for sealing an opening of a container such as a milk bottle, a sealing method using a paper stopper has been widely used.

[0003] However, this method has the advantages that the sealing structure and the process of attaching the paper stopper are simple and can be performed at low cost, but the tamper-evident property (property of preventing unauthorized opening) is insufficient, and the safety of the contents is low. Is not fully assured, leakage of the contents is not completely prevented at the distribution stage, and the container needs to be formed in a middle-thick wall shape in order to install a paper stopper. It has drawbacks that it cannot be achieved and is not suitable for resealing after opening. Further, in order to enhance the tamper-evident property, a film or the like is often put on the opening of the container. However, the tamper-evident property is still insufficient, and the number of steps is increased, resulting in an increase in cost.

In order to solve these problems, a method has been proposed in which a cap made of a synthetic resin having tamper-evident property is attached to the opening of a container (Japanese Utility Model Application Laid-Open No. 63-11 / 1988).
No. 4955, JP-A-9-58719, etc.). However, these methods are superior in the tamper-evident property and the sealing property as compared with the method using a paper stopper.However, when the cap is to be labeled, the label must be printed directly on the synthetic resin. However, there are drawbacks such as a higher printing cost and a tendency for the printed ink to drop off, as compared with the case of printing on a medium.

[0005] Further, even if a conventional synthetic paper cap is attached after the conventional paper stopper is attached to the opening of the container,
There are drawbacks such that the display on the paper stopper becomes difficult to see, the number of steps increases, and the cost increases.

[0006]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned drawbacks of the conventional container sealing cap, facilitates display printing, simplifies the manufacturing process, reduces the manufacturing cost,
Further, it is another object of the present invention to provide a cap with an indicator that can be easily collected from a container and easily recycled.

In other words, the holding portion 3 has a circular concave portion into which the display device can be fitted, and the diameter of the bottom surface of the concave portion is slightly larger than the inner diameter of the most visited portion on the inner peripheral surface. The inner peripheral surface of the recess has a shape gradually inclined inward. In addition, the degree of inwardness is such that the display device 6 can be easily attached to and detached from the holding unit 3 and can be easily used in a natural state.
That is, the design is designed such that the display 6 does not detach from the holding unit 3 unless a forced force is applied from the outside. Further, the holding portion 3 becomes gradually thinner as it goes upward, and the upper end portion of the holding portion 3 is shaved to make it easier to mount the display 6 in the holding portion 3. In addition,
In the cap with a display device of the present invention, as long as the cap has the above function, the holding portion does not necessarily have to be annular,
For example, it may be provided intermittently on the top surface.

The display device 6 is a member having an upper surface on which necessary indications such as a product name and a manufacturer name are attached, and has a shape capable of being held in the holding portion 3. A circular plate having an outer shape slightly larger than the inner diameter of the part. Display 6
The material is not particularly limited as long as it has sufficient hardness to be held in the holding portion 3, but is usually used for milk bottles for reasons such as ease of printing and cost. A paper having a certain thickness, such as a paper stopper to be used, is used. That is, the cap 1 does not require a special method of printing directly on a synthetic resin when displaying, and can use a normal printing method on paper.

The side score portion 4 is provided circumferentially at the lower end of the outer shell portion 8, and the tamper-evident band portion 5 formed below the side score portion 4 is removed from the cap portion 2 when the container is opened. It is a portion formed to be thin so that it can be easily torn. The tamper evidence band portion 5 is provided below the side score portion 4 and includes a ring portion 12, a vertical score portion 13, a knob 14, a ridge 15 and a side hole 19.

The ring portion 12 is connected to the lower end of the outer shell portion 8 via the side score portion 4, and has the same inner diameter as the outer shell portion 8 (FIG. 3). The ring portion 12 is designed to fit on the outer peripheral surface of the container when the cap 1 is mounted on the container. The ring section 12 is provided with a vertical score section 13. The vertical score portion 13 has a thin wall thickness similar to that of the side score portion 3 and is easily severable. As shown in FIGS. 1B and 1C, the vertical score portion 13 rises obliquely from the lower end portion of the ring portion 12, and then rises horizontally. And reaches the lower end of the side hole 19. The side hole 19 is a hole provided adjacent to the vertical score portion 13 and the side score portion 3.

In the vicinity of the upper end of the vertical score section 13, a knob 1 is provided.
4 are provided. FIG. 4A is an enlarged plan view of the knob 14. The grip portion 14 includes a foot portion 20 provided adjacent to the side score portion 4, the vertical score portion 13, and the side hole 19, a grip portion 21 coupled to a tip of the foot portion 20, a ring portion 12 and a grip portion 21. And an auxiliary foot portion 23 connected to the second member. The auxiliary foot 23 is a member that can be easily cut by applying an outward force to the grip 21 when removing the tamper-evidence band 5,
When the cap 1 is continuously stoppered and stored, the cap 1 attached to an adjacent container is supported.
Has the function of preventing the knob portions of the lock members from locking each other. Further, the grip 21 has a jaw 22 protruding from the foot 20 on the side opposite to the side hole 19.

An annular ridge 1 is provided on the inner peripheral surface of the ring portion 12.
5 are provided. The protrusion 15 has the same inner diameter as the protrusion ring 10 (FIG. 3), and is designed to be engageable with a circumferential groove provided on the outer peripheral surface of the container. The tamper-evident band portion 5 has the above-described structure, so that when the container is not opened, the tamper-evident property (tamper-evident prevention property) of the cap 1 is ensured. At the time of opening, the side score portion 4 and the vertical score portion 13 are removed from the cap 1 by tearing.

The inner diameter of the ridge 15 is designed to be slightly smaller than the outer diameter of the peripheral groove of the container to be engaged. The degree of the reduction is caused by the fact that the cap 1 can be easily attached to the container and the inner diameter of the ridge 15 is smaller than the outer diameter of the peripheral groove when the cap 1 is attached to the container. A force is applied to the outer portion 12 in the outward direction, and as a result, a force is applied inward to the holding portion 3 at the upper end of the outer shell portion 8 formed integrally with the ring portion 12, so that a force is applied to the inside of the holding portion 3. This is an extent to which the attached display device 6 can be more firmly held. In other words, ridge 15
Has a height equal to or greater than a certain value, so that the holding force of the holding unit 3 with respect to the display device 6 is increased. In addition, the ridge 15
If it is provided on one circumference, it may not necessarily be annular, and may be partially cut or provided intermittently.

Next, the method of use and operation of the cap 1 will be described. First, the display 6 is mounted in the holder 3. As described above, since the holding portion 3 is made of a material which is gradually inwardly directed upward and is elastically deformable, the outer diameter of the holding portion 3 is slightly larger than the inner diameter of the opening of the holding portion 3. By pushing the display 6 having the display 6 into the holder 3, the display 6 can be closely fitted to the holder 3. Further, due to the inward direction of the holding unit 3, the display device 6 once mounted does not detach from the holding unit 3 unless a force is applied from the outside.

The cap 1 is moved from the lower end of the cap 1
It can be mounted on the container 16 by pushing it into the opening of the container 16, whereby the container 16 is sealed. As described above, the provision of the holding portion 3 on which the display device 6 can be fitted is provided on the top surface 7 because when the cap 1 is loaded into the opening of a container, for example, a bottle using a stoppering machine.
This means that the special technical effect that the fitting of the display device 6 to the holding portion 3 and the mounting of the cap 1 to the opening of the container can be performed at the same time is achieved. That is, the fitting of the indicator 6 and the fitting of the cap 1 to the container opening can be performed by one operation. For example, a cap holding member that can hold the cap 1 and can move up and down, a fixed body (pressed body) having a lower end surface having the same shape as the display device 6 above the cap 1 held by the cap holding member, When a stoppering device including a vertically movable holding device that holds the container so as to be located directly below the cap 1 is used, the indicator 6 is lightly placed in the concave portion of the cap 1. By raising the container toward the cap 1, fitting the cap 1 into the opening of the container, further raising the cap 1 and the container, and pressing the cap 1 together with the indicator 6 against the lower end surface of the fixed body, With a single rising operation, the cap can be attached to the container mouth and the indicator can be fitted and attached to the recessed portion of the cap. When the cap 1 is pushed into the container 16, the cap 1 receives an internal pressure from the inside of the container. As described above, since the top surface 7 of the cap 1 has a structure curved downward, the internal pressure is reduced. It can be effectively eliminated. FIG. 5 is an enlarged cross-sectional view of a part of the cap 1 and the container 16 when the cap 1 is mounted on the container 16.

The protruding ring 10 and the protruding ridge 15 are formed in an upper circumferential groove 17 which is two circumferential grooves provided near the container opening.
And the lower peripheral groove 18 respectively. As described above, since the inner diameter of the ridge 15 is designed to be slightly smaller than the outer diameter of the lower circumferential groove 18, when the cap 1 is mounted on the container 16, the ring portion 12 provided with the ridge 15 Spread slightly outward. This allows the top surface 7 to be
An inward force is applied to the holding portion 3 with the periphery of the fulcrum as a fulcrum. Then, the display device 6 mounted in the holding unit 3
The holding section 3 holds the sheet more strongly.
That is, by attaching the cap 1 to the container,
It has a structure that generates a stronger holding force on the display 6 than when it is not mounted on the container. Therefore, when the cap 1 is not attached to the container, the display 6 is easily detachable, whereas when the cap 1 is attached to the container, the display 6 is not easily detached from the holding portion 3. Further, in the cap 1, since the outer shell 8 and the ring 12 are designed to have the same inner diameter, the lever principle is more effective than when the inner diameter of the ring 12 is larger than the inner diameter of the outer shell 8. And the indicator 6 can be more strongly held by the holder 3. For this reason, it is usually unnecessary to bond the display 6 to the top surface 7.

When opening the container 16, the cap 1
Works as follows. As shown in FIG. 4B, when a force is applied to the grip 21 of the knob 14 in the direction in which the vertical score 13 is provided, the auxiliary foot 23 is cut off, and the jaw 2 is cut.
The tip of 2 contacts the ring portion 14. Further, the grip 21
Is applied to the ring portion 12 connected to the foot portion 20 by the lever action with the tip of the jaw portion 22 as a fulcrum, and the vertical score portion 13 and the side score portion 3 are torn. That is, the cap 1 has a structure in which the initial force necessary for tearing the longitudinal score portion 13 and the side score portion 4 is reduced by utilizing the principle of leverage so that the container can be easily opened.

Further, the grip portion 21 is pulled along the outer periphery of the container, the longitudinal score portion 13 and the side score portion 4 are torn, and the tamper-evident band portion 5 is removed from the cap portion 2. Thereafter, the grip tab 11 is pushed upward, the cap portion 2 is removed from the container 16, and the container 16 is opened. The cap 1 from which the tamper-evident band portion 5 has been removed is detachable from the container 16.

When the used cap 1 is discarded, the cap 2 and the display 6 can be separated as follows. By applying a downward force to the outer shell 8, the cap 2 is deformed into a distorted state,
The tight fitting state of the display 6 to the holding unit 3 is released. Since the display device 6 is attached to the holding unit 3 without using an adhesive, a jig such as a nail or a needle is inserted into a gap generated between the holding unit 3 and the display device 6, and the display device 6 is inserted. Can be removed from the holding unit 3. This work can be performed in the same manner in both manual work and mechanical work. That is, in the cap 1, the separation and collection in each household and the mechanical continuous separation after the used cap is collected by the trader can be easily performed. Therefore, the cap 1 is effective in recycling resources.

The cap 1 other than the display 6 can be manufactured by a known method of molding a synthetic resin or the like. The display device 6 can also be manufactured by a known method of manufacturing a paper stopper or the like.

The assembly of the cap 1 and the mounting of the cap 1 on the container 16 can be performed separately, but can be performed in a single step as described above as follows. The display device 6 is placed on the opening of the holding portion 3 of the cap 1 to which the display device 6 is not attached. This cap 1 is placed over the opening of the container 16. The cap 1 is pushed into the container 16 from above the display 6 using a tapping machine. Thus, the attachment of the display device 6 to the cap and the attachment of the cap 1 to the container 16 are completed at the same time.
That is, the cap 1 can be assembled and mounted in one step, and the manufacturing process can be simplified.
