Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container with a seal lid, and more specifically, removing the flange at the mouth of the container body by opening the lid to fill the filling such as yogurt for beverages and hail in the container body. The present invention relates to a container with a seal lid that can be easily taken or eaten.

[0002]

2. Description of the Related Art A container with a seal lid is generally used in which a filling material is contained in a cup-shaped container body made of a synthetic resin having a flange at its mouth, and a lid is adhered and sealed on the upper surface of the flange.

[0003]

The above-mentioned conventional container with a sealed lid only peels off the lid from the upper surface of the flange when the lid is opened when drinking the filling, and the flange is a container. It remains on the body side.

Therefore, when the filling is made of beverage yogurt or the like, there is a problem that the flange interferes when drinking the filling with the lips attached to the mouth of the container, which makes it difficult to drink.

Further, in the conventional container with a seal lid of this kind, in order to make the lid easy to peel off, the lid is adhered to the upper surface of the flange with an adhesive having a relatively weak adhesive ability. Therefore, even if the lid is slightly peeled off, the appearance of the container does not change, and it is difficult to identify whether the container with the seal lid has been opened once.

Therefore, an object of the present invention is to make the shape of the container body easy to eat and drink when it is used for packaging foods and drinks such as yogurt for drinks and hail, and when the filling material is consumed or eaten. Another object of the present invention is to provide a container with a seal lid, in which the unopened property of the container can be confirmed, and the container body can be manufactured by injection molding using an existing mold.

Further, in the conventional container with a seal lid, as described above, the lid is easily peeled off by making the adhesive strength between the flange and the lid easy to peel, so that the lid is bonded to the flange. It is difficult to control the heat-sealing strength in the process, and it is not easy to manufacture one having a uniform adhesive strength.

Therefore, the object of the present invention is to bond the flange and the lid with a strong adhesive strength without making the adhesive strength easily peelable. An object of the present invention is to provide a container with a seal lid that does not require heat strength control.

[0009]

The above object can be achieved by a container with a seal lid according to the present invention having the following configuration.
That is, in the container with a seal lid of the present invention, a flange is integrally formed at the mouth of a cup-shaped container body, and a filling piece is stored inside the container body, and a tab is provided on the upper surface of the flange. A container with a seal lid, in which a lid is adhered and the mouth of the container body is completely sealed, in which a label is placed on the inner surface of a mold and the container body is molded by injection molding of synthetic resin at the same time. The container body is reinforced by attaching a label to the outer circumference of the peripheral wall portion of the container body, and the flange-side end of the label is located near the base of the flange, and near the base of the flange. A ring-shaped weak portion is provided around the flange, and the flange is removed from the ring-shaped weak portion provided around the base of the flange by the lid opening operation by pinching the knob of the lid. In which is configured to be taken tear in a state of adhering to the back surface.

In the container with a seal lid according to the present invention having the above structure, it is preferable that the lid is adhered to the upper surface of the flange via an adhesive layer.

[0011]

In the container with the seal lid of the present invention, the label is placed on the inner surface of the mold, and the label is attached to the outer periphery of the peripheral wall portion of the container body at the same time when the container body is molded by injection molding of synthetic resin. The container body is reinforced by, and by arranging the end of the label on the flange side in the vicinity of the root of the flange, a weak portion is provided in a ring shape around the vicinity of the root of the flange, and a container with a seal lid is provided. It is configured to be torn off from the ring-shaped weak body portion provided around the base of the flange by the lid opening operation by picking the knob of the lid. There is.

Therefore, when the container with the seal lid of the present invention is to be opened to drink or eat the filling contained in the container body, it is provided in a ring shape around the base of the flange. The flange is torn off from the weak portion, and the flange is attached to the lid, and then removed from the container body to open the lid.

As a result, the container body becomes a complete cup type container without a flange. Therefore, even if the filling material is a drink jelly such as a yogurt for drinks or konjac jelly, it is as if the filling material is contained in an ordinary cup. Like when you drink, you can drink by putting your lips on the mouth of the container body,
Therefore, it is possible to make the container body easy to drink. Further, even if the filling material is a solid material such as hail, it can be used in the same manner.

Further, in the container with the seal lid of the present invention, since the flange integrally formed with the container body is torn off at the same time as the lid is opened, even if a small portion is opened,

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The concrete structure of the container with a seal lid of the present invention will be described below with reference to the accompanying drawings. 1 to 5 show one embodiment of a container with a seal lid according to the present invention. FIG. 1 is a perspective view showing a state in which the lid is almost half opened, and FIG. 2 is a longitudinal sectional view showing the state before the lid is opened. 3 is an enlarged vertical sectional view of a part of the state before opening the lid, FIGS. 4 (A) and 4 (B) are partially enlarged sectional views showing the process of opening the lid, and FIG. 5 is a view of the container with the lid fully opened. FIG.

In these illustrated embodiments, the container body 1 is formed into a cup type having a thread bottom. This container body 1
A filling 9 such as a yogurt for drinks is housed inside.

A flange 2 is integrally formed at the mouth of the upper part of the container body 1. A lid 3 having a tab 4 is strongly adhered to the upper surface of the flange 2,
The lid 3 completely seals the mouth of the container body 1.

Further, a label 6 is placed on the inner surface of the mold on the entire outer circumference of the peripheral wall portion of the container body 1, and at the same time when the container body 1 is molded by injection molding of synthetic resin, the peripheral wall portion of the container body 1 is formed. There is a label 6 attached to the outer periphery.

The container body 1 is made of high impact polystyrene (HIPS) containing white pigment, for example, and has a wall thickness of about 0.6 mm.

The lid 3 is composed of a biaxially oriented polyethylene terephthalate film having a thickness of 16 μ / aluminum foil having a thickness of 15 μ / a polyethylene resin layer having a thickness of 30 μ / a vinyl acetate adhesive layer (heat sealing layer) having a thickness of 25 g / m ^2. It is formed of a laminated sheet and is strongly adhered to the upper surface of the flange 2 of the container body 1 via the heat seal layer 5.

In this embodiment, the label 6 is formed in a shape in which the peripheral wall portion of the container body 1 is expanded with paper. Then, a label having a shape in which the peripheral wall portion of the container body 1 is developed is rolled into a tubular shape, and at the time of injection molding of the container body 1, one end of the label is positioned at the base of the flange of the container body to be molded. As described above, the label 6 is set along the inner peripheral surface of the injection molding die, and the synthetic resin 1 is injection-molded thereinto, so that the label 6 is pressure-bonded to the entire outer periphery of the peripheral wall portion.
The attached container body 1 is molded.

As described above, the container body 1 is reinforced by attaching the label 6 to the entire outer periphery of the peripheral wall portion of the container body 1 during injection molding of the container body 1.

Since the end of the label 6 on the flange 2 side is located at the base of the flange 2, the label 6
A weak portion 7 is formed in a ring shape around the base of the flange 2 where there is no.

The container with a seal lid according to the above embodiment is used and operates as follows. That is, as can be seen from FIGS. 1 and 2, this container with a seal lid is filled with a filling material 9 such as a yogurt for beverage inside the container body 1.
Then, the lid 3 is strongly adhered to the upper surface of the flange 2 by the heat seal layer 5 to seal the filler 9
To package. Then, when the filling 9 in the container is to be drunk or eaten, an operation is performed in which the knob 4 provided on the lid 3 is pinched with a fingertip and the lid 3 is peeled off.

In this embodiment, the label 6 is attached to the entire outer periphery of the peripheral wall of the container body 1 to reinforce the container body 1, while the end of the label 6 on the flange 2 side is attached to the base of the flange 2. By arranging in the portion, a ring-shaped weak body portion 7 is provided around the base of the flange 2.
Moreover, the lid 3 is strongly bonded to the upper surface of the flange 2 via the heat seal layer 5.

Therefore, when a force is applied to the fingertip to peel off the lid 3, the force of the fingertip does not separate the lid 3 firmly adhered to the flange 2 from the flange 2. Due to the so-called notch phenomenon, the crevice 8 is generated in the weak body portion 7 near the base of the flange 2, as shown in FIGS. 4 (A) and 4 (B). The part of the flange 2 is torn off.

As a result, as shown in FIGS. 1 and 4B, the flange 2 is removed while being attached to the back surface of the lid 3. That is, as shown in FIG. 5, it becomes a cup type container without a flange.

Therefore, it becomes possible to drink or eat the filling 9 by putting the lips on the mouth of the container body 1, and the container body 1 is filled with a filling such as a yogurt for drink or hail as the filling 9. Even when it is put, the filling 9 becomes easy to drink or easy to eat.

Further, even if the lid 3 is slightly peeled off, the flange 2 is torn off together with the lid 3, so that the opened state can be seen at a glance, so that the unopened property of the container can be maintained. It is possible to prevent unauthorized opening.

Furthermore, since the adhesive strength between the lid 3 and the flange 2 is not easy peeling and is a strong adhesive, control in the step of adhering the lid 3 to the flange 2 is unnecessary.

Next, FIG. 6 is a partially enlarged vertical sectional view showing another embodiment of the container with a seal lid of the present invention.
(A) And (B) is a partial expanded sectional view which shows the process of opening a lid.

In the embodiment shown in FIGS. 6 and 7, the label 10 having the adhesive layer 11 is attached to the entire outer periphery of the peripheral wall portion of the container body 1. This label 10 is one in which the label 10 is placed on the inner surface of the mold and is attached to the entire outer periphery of the peripheral wall portion of the container body 1 at the same time as the container body 1 is formed by injection molding of synthetic resin.

That is, the label 1 having the adhesive layer 11
As in the case of the embodiment shown in FIGS. 1 to 5, 0 is set in a tubular shape in advance along the inner peripheral surface of the injection molding die, and the synthetic resin is injection molded therein. As a result, the container body 1 in which the label 10 is attached to the entire outer circumference of the peripheral wall portion via the adhesive layer 11 is formed.

The label 10 is formed of, for example, a polyethylene terephthalate film having a vinyl acetate adhesive layer 11 in a shape in which the peripheral wall portion of the container body 1 is expanded.

In this embodiment, the label 10 is wrapped around the lower surface of the flange 2 integrally attached to the container body 1 with a width of, for example, about 1 mm. As a result, the weak portion 12 is provided in a ring shape in the vicinity of the end of the label 10 on the flange 2 side, that is, near the base of the flange 2.

The other structure of this embodiment is the same as that of the embodiment shown in FIGS.

In the container with the seal lid shown in FIG. 6 and FIG. 7, when the gripping piece 4 of the lid 3 is sandwiched by the fingertips and a force is applied to the fingertips in order to peel off the lid 3, the lid 3 is firmly adhered to the flange 2. Without separating the lid 3 from the flange 2
The force of the fingertip is concentrated and applied to the weak portion 12 provided in a ring shape near the base of the flange 2. As a result, FIG.
As shown in (A), the crevasse 13 is attached to the weakened portion 12.
Occurs, and the flange 2 is torn off from this portion.

As a result, when the lid 3 is fully opened, one portion of the flange 2 remains on the mouth side of the container body 1 due to the overlap of the label 10 on the lower surface of the flange 2, and the label body 10 is left on the mouth part of the container body 1. The flange 2 can be removed to the extent that even if the lips are attached, there is almost no discomfort.

Therefore, also in this embodiment, the container body 1 containing the filling 9 can be used like a normal cup type container, and the filling 9 can be easily drinkable or eaten. It will be possible.

Also in this embodiment, when the lid 3 is peeled off, the flange 2 is torn off together with the lid 3, and even if it is slight, it can be seen at a glance, so that the container can be held unopened. It is effective and can prevent unauthorized opening.

Furthermore, in the container with the seal lid of this embodiment, since the label 10 having the adhesive layer 11 is used, the end of the label 10 where the adhesive layer 11 does not exist and the container body 1 are separated. The adhesive strength between them is weaker than the adhesive strength between the adhesive layer 11 on the back surface of the label 10 and the container body 1.

Therefore, when a force is applied to the fingertip in an attempt to peel off the lid 3, the force is concentrated on the weak portion 12 provided in the ring shape near the base of the flange 2 and the weak portion 12 is applied. The so-called notch phenomenon caused by the crevasse 13 is more effectively generated, and the part of the flange 2 can be torn off extremely accurately.

The label 10 having the adhesive layer 11 is formed.
In the case of using, the poorer the affinity between the material of the label 10 and the material of the container body 1, the more easily the crevice 13 is generated in the weak portion 12, and the so-called notch phenomenon occurs more effectively.

[0046]

As described above, in the container with a seal lid of the present invention, a label is attached to the outer periphery of the peripheral wall of the container body to reinforce the container body, and the end of the label on the flange side is attached. By being located near the base of the flange, a ring-shaped weak body portion is provided around the base of the flange, and from the ring-shaped weak body portion provided around the base of the flange by the opening operation, It is configured to be torn off with the flange attached to the back surface of the lid.

For this reason, when an attempt is made to open the lid for drinking or eating the filling contained in the container body, the flange is removed from the weakened portion provided in the shape of a ring around the base of the flange. It is torn off and removed from the container body with the flange attached to the lid.As a result, the container body becomes a cup-shaped container without a flange, so you can drink the filling as if it were in a normal cup. Like eating, the mouth of the container body can be attached to the lips to drink or eat, that is, the filling can be easily or easily eaten.

Further, since the flange integrally formed with the container body is torn off by the lid opening operation, even if it is a little, it can be seen at a glance that the container has been opened, which is effective in preventing unauthorized opening of the container. .

Further, the label is positioned and set in a mold for injection molding so that one end of the label is located near the base of the flange of the container to be manufactured.
Since the container body is molded by performing ordinary injection molding of synthetic resin, it can be manufactured using an existing injection molding die.

According to the container with a seal lid described in claim 2, since the lid is adhered to the upper surface of the flange via the adhesive layer, the adhesive strength between the upper surface of the flange and the lid is high. By opening the lid, the flange from near its base,
There is an effect that can be more accurately torn off.

Further, since the container with a seal lid of the present invention is one in which the lid and the lid of the container body are adhered with a strong adhesive strength without making the adhesive strength between the flange and the lid easily peelable, There is an advantage that it is not necessary to control the heat seal strength in the step of adhering to.
