Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container having a canopy for closing an opening and a container canopy for closing an opening of the container.

[0002]

2. Description of the Related Art Generally, a container having an opening has a canopy to close the opening. A container provided with such a canopy securely closes the opening so that the inside of the container is closed. It is required that it can be sealed. Therefore, the canopy is provided with a skirt portion corresponding to the opening side portion, and the engagement state is secured between the skirt portion and the container main body to seal the gap between the edge portion of the opening portion and the canopy. I am trying to do it.

In order to engage between the skirt portion and the container body, hitherto, an engaging portion, for example, an annular ring extending over the entire circumference of the body outer surface of the container body, has been used. A protrusion is provided, and a locked portion, such as an annular hook, that can be engaged with this locking portion is provided on the inner peripheral surface of the skirt. It is designed to be in close contact with the edge.

Some canopies are provided with openable and closable holes so that the contents can be taken out. The holes are mainly provided for taking out the contents, If this hole is used when filling the contents into the container body, the disadvantage that the filling amount per unit time is small will occur.Therefore, the contents can be filled into the container body only by removing the canopy from the container body. The opening of the main body is opened.

When the canopy is removed from the container body, the above-mentioned engagement between the skirt portion and the container body is released. This engagement is intended to seal between the canopy and the container body. The strong engagement state is ensured, and the canopy cannot be easily removed from the container body as it is.

Therefore, conventionally, a canopy provided with vertical cuts at a plurality of places (for example, eight places) of the skirt is used, and when the canopy is removed from the container body, each of the cuts is removed by a driver or the like. By cutting open to the lower end of the skirt, the skirt portion can be easily widened and the engagement between the locking portion and the locked portion can be easily released.

The cut portion functions as a virgin seal of the canopy with respect to the container. That is, when the notch is not cut open, it means that the canopy has not been removed from the container body, and in addition to providing a virgin seal in the hole for taking out contents,
After the product is shipped, it will be guaranteed to be new.

[0008]

As described above, in the conventional container, only the engagement between the locking portion provided on the container main body and the locked portion provided on the skirt portion of the canopy by the single circling portion. Maintains the sealing action between the container body and the canopy, and if the engaging force is increased to secure this sealing action, it becomes difficult to remove the canopy from the container body. There is a problem.

That is, when the engagement force between the container main body and the canopy is set to be weak, the canopy may easily come off due to a shock to the container during handling such as transportation. If the engagement force between the skirts is set to be strong, when the number of cuts provided on the skirt is small, the engagement force does not become weak even when the skirt is cut open, and the canopy cannot be easily removed from the container body. Have

Further, since the canopy is curved when it is removed from the container body, if the skirt has a large number of cuts, a large force is applied to the cuts when it is deformed by external force or when the canopy is attached. This may cause cracks in the cuts, especially when the canopy becomes unusable if the number of times the canopy is attached and detached is increased, and because the cuts are cut open, the opening will not be sealed when the canopy is attached again. However, there is a problem in that the function as a canopy may be impaired.

Further, if a large number of cuts are provided to facilitate the expansion of the skirt, each of these cuts needs to be cut open with a screwdriver or the like, which is troublesome for the operator. Further, there is a problem in that the notched portion can be visually observed from the outside, which makes the entire container unattractive.

Therefore, according to the present invention, the seal between the canopy and the container body can be surely maintained at the time of shipping the product or at the time of transportation, and when the user tries to remove the canopy from the container body. Preparatory work required only once and subsequent removal operation are simplified, and the function of the canopy is not impaired even if the canopy is attached to and detached from the container body multiple times after completion of this preparatory work. The purpose is to

[0013]

A container according to the present invention is provided with an upper side engaging portion and a lower side lower engaging portion following the upper side engaging portion, for example, on the opening side portion of the outer peripheral surface of the body portion. The main body and the upper part of the skirt corresponding to the opening side portion of the container body are provided with an upper locking part and an upper locked part that is in a state of being engaged, for example, around the entire circumference of the skirt. It consists of a lower locking part and a canopy provided with a lower locked part that is in an engaged state. By cutting off the lower part of the skirt part, the space between the lower locking part and the lower locked part is cut off. The engagement state of is released.

Further, the container canopy of the present invention is provided with a skirt portion corresponding to the opening side portion of the outer peripheral surface of the body of the container body, and the opening side portion of the container body is provided above the skirt portion. The upper locking portion is provided with an upper locked portion that is engaged with, for example, the entire circumference of the upper locking portion, and the lower part that can be cut off of the skirt portion is in a state of being engaged with the lower locking portion of the opening side portion. Each of the locked parts is provided, and the lower part of the skirt is cut off while being attached to the container body so that the engagement between the lower locked part and the lower locked part is released. It was done.

As the shape to be cut off in the skirt portion of each of the container and the container canopy, one having a piece for removing the canopy extending downward from a part of the upper portion of the skirt after cutting is used. You may

It should be noted that, under the restriction that the sealing condition between the opening of the body and the skirt is kept within a predetermined range,
The upper locking part and the lower locking part on the outer peripheral surface of the body part, and the upper locked part and the lower locked part on the inner peripheral surface of the skirt part are partially covered in one round of the corresponding peripheral surface. You may make it form only in the removed part.

However, in order to ensure this sealed state, at least the upper engaging portion and the upper engaged portion closer to the contents of the container body are provided on the outer peripheral surface of the body portion and the inner peripheral surface of the skirt portion. It is desirable to form it over the entire circumference.

[0018]

As described above, the upper locked portion engages with the upper locking portion of the container body at the upper portion of the skirt portion, and the lower locked portion at the lower portion of the cuttable skirt portion has the lower locked portion below the container body. Since the canopy is engaged with the side locking part, the canopy is securely held in the opening side part of the container body by the double engagement, and the opening side part and the canopy are securely sealed. I have to.

Then, the lower portion of the skirt is cut off to release the engagement between the lower locking portion and the lower locked portion, so that the canopy has the upper locking portion and the upper locked portion. It will be held in the container body only by the engagement between. Therefore, the engagement force between the skirt portion and the container body becomes weaker, and it becomes easier to remove the canopy from the container body than in the case of double engagement up to that point.

That is, before the lower part of the skirt is cut off, the canopy cannot be easily removed because the two engagements are maintained, but after the lower part of the skirt is cut off, the upper locking part and the upper side Only the engagement with the locked portion is performed, and since the engagement is performed near the opening, the canopy can be easily removed.

Further, the canopy removal operation piece is formed after the lower part of the skirt is cut off,
By holding the canopy removal operation piece and pulling it upward, the engagement between the upper locking portion and the upper locked portion can be easily released, and thus the canopy is easily removed from the container body. It becomes possible.

The object taking-out hole portion, 15 is a canopy removing piece portion, and 16 is a thick portion.

As shown in FIG. 1, the container body 1 is provided with an upwardly directed opening portion 1a (see FIG. 3), and the outer peripheral surface of the body portion 2 is provided at the opening portion 1a side. A hook-shaped upper locking portion 3 that faces is provided. Further, on the outer peripheral surface of the body portion 2, a lower locking portion 4 located below the upper locking portion 3 is provided, and an annular projecting piece 5 is provided below the lower locking portion 4.

The upper locking portion 3 and the lower locking portion 4
Are provided in an integrated state with the container body 1, but the invention is not limited to this, and they may be formed separately and attached to a predetermined location of the container body 1. The container body 1 is made of synthetic resin such as plastic or metal as its material.

Next, the canopy 6 attached to the opening 1a side of the container body 1 is provided with a skirt portion 7 into which the opening 1a side portion of the outer peripheral surface of the body portion 2 can be fitted. Is provided in a state where the upper portion 8 and the lower portion 9 are connected to each other through the lateral groove 10, and the portion of the lower portion 9 can be cut off from the upper portion 8 along the lateral groove 10.

As shown in FIGS. 1 and 2, a hook-shaped upper engaged portion 11 engageable with the upper engaging portion 3 is provided on the inner peripheral surface of the upper portion 8 and the inner portion of the lower portion 9 is A hook-shaped lower locked portion 12 that can be engaged with the lower locking portion 4 is provided on the peripheral surface. When these are engaged, the packing 13 provided on the canopy 6 comes into close contact with the edge portion of the opening 1a, thereby sealing the inside of the container body 1.

Since the two upper and lower engaged states are secured in this manner, the canopy 6 cannot be easily removed from the container body 1. At this time, the annular protruding piece 5 functions to protect the engagement between the lower locking portion 4 and the lower locked portion 12 from below. Each of the upper locking portion 3, the upper locked portion 11, the lower locking portion 4, and the lower locked portion 12 should be provided over the outer circumference of the body 2 and the inner circumference of the skirt 7. However, the present invention is not limited to this, and it may be provided at a plurality of positions that divide the circumference so that the two engage with each other.

The upper locking portion 3 and the upper locked portion 11
The engagement between the lower locking portion 4 and the lower locked portion 12 is not limited to the hook-shaped one as shown in the drawing, and, for example, a protrusion is formed on the outer peripheral surface of the body portion 2. It is also possible to provide either one of the hole and the hole and provide the skirt 7 with the other so that the projection and the hole engage with each other.

Further, it means that the canopy 6 has not been removed until the lower portion 9 of the skirt portion 7 is cut off, which also has a function as a so-called virgin seal. It should be noted that the canopy 6 is provided with an openable / closable contents taking-out hole 14, and the contents stored in the container body 1 are taken out from the contents taking-out hole 14.

Next, when the canopy 6 is attached to the container body 1, as shown in FIGS. 3 and 4, by forcibly fitting the opening 1a side portion of the container body 1 in the skirt portion 7, The engaging portion 3 and the upper engaged portion 11 and the lower engaging portion 4 and the lower engaged portion 12 are brought into an engaged state.

That is, when the canopy 6 is forcibly fitted into the container body 1, first, in the upper locked portion 11 and the lower locked portion 12, the taper surface 11a and the taper surface 12a are respectively the upper locking portions. It is pushed outward by being guided by 3 or the lower locking portion 4, whereby the upper portion 8 and the lower portion 9 are pushed outward against the elastic force of themselves.

After that, when the upper locked portion 11 and the lower locked portion 12 cross over the upper locked portion 3 or the lower locked portion 4, the upper portion 8 and the lower portion which are once spread outwardly. 9 contracts by their own elastic force, so that the upper locking portion 3 and the upper locked portion 11 as well as the lower locking portion 4 are
Further, the engagement between the lower locked portions 12 is as shown in FIGS. 1 and 2.

Subsequently, when removing the canopy 6 from the container body 1, first, a rod-shaped member such as a screwdriver having a sharp tip is inserted into the insertion portion 10b to cut open the vertical groove 10a, and further, as shown by a dotted line in FIG. Then, by pulling the cut-out piece of the lower part 9, the lower part 9 is cut open along the lateral groove 10 and is cut off from the upper part 8 when the skirt part 7 is rotated once.

The horizontal groove 10 and the vertical groove 10a are shown in FIG.
As shown in FIG. 5, the predetermined portion of the skirt portion 7 is formed thin and formed into a groove shape that can be easily cut open, but the present invention is not limited to this, and instead of this groove shape, For example, a broken line may be used.

By cutting off the lower portion 9 of the skirt portion 7, the engagement between the lower locking portion 4 and the lower locked portion 12 is released, whereby the canopy 6 is fixed to the upper locking portion. 3 is attached to the container body 1 only by the engagement between the upper side locked portion 11 and the upper locked portion 11, and the engaging force as a whole is weakened as compared with the initial state. The work to remove from 1 becomes easy.

When the removed canopy 6 is attached to the container body 1 again, the upper portion 8 of the skirt portion 7 is fitted into the opening portion 1a of the container body 1 so that the upper locking portion 3 and the upper locked portion 11 are connected to each other. To be engaged.

Next, as shown in FIG. 5, the lower portion 9 of the skirt portion 7 has a canopy removal operation piece extending downward from a part of the upper portion 8 of the skirt portion 7 after being cut, as a shape to be cut. You may make it use the thing in which the part 15 is formed. That is, the skirt portion 7 has a lateral groove.
Two vertical grooves 10a and 10c following 10 are provided with a predetermined width.

Therefore, as shown in FIG. 6 (a), a screwdriver or the like is inserted into the insertion portion 10b to cut open the vertical groove 10a, and then, as shown in FIG. 6 (b), the vertical groove 10a of the lower portion 9 is formed. By cutting the side portion along the horizontal groove 10 to the vertical groove 10c, the lower portion 9 is cut from the upper portion 8 with the canopy removal operation piece 15 left as shown in FIG. 6 (c). Become.

At this time, since the thick portions 16 are provided on both sides of the canopy removing operation piece 15 so as to block the lateral groove 10, the canopy removing operation piece 15 is not cut off at the same time as the lower portion 9 is cut off. I have to. Note that the lateral groove 10 may not be provided in the portion of the canopy removal operation portion 15.
Further, it is optional whether the lower locked portion 12 is provided in the lower portion of the canopy removal operation piece 15.

When the canopy removal operation piece 15 is provided, the canopy 6 is removed after the lower portion 9 is cut off as shown in FIG.
When removing the canopy,
It is possible to more easily release the engagement between the upper locking portion 3 and the upper locked portion 11 by pulling up and holding it. In the case where the lateral groove 10 is provided between the thick portions 16, the lateral groove 10 facilitates bending of the canopy removal operation piece 15 and is easy for the user to use.

Further, the canopy removal operation piece 15 is not limited to the shape shown in the figure, and for example, the one where the lower end of the canopy removal operation piece 15 is located below the lower portion 9 is used. Moreover, the canopy removal operation piece 15 is not limited to a single piece, and a plurality of pieces may be provided on the skirt 7. In this case, the canopy removal operation piece 15
It is necessary to cut off each of the lower portions 9 sandwiched between.

Thus, until the lower portion 9 of the skirt portion 7 is cut off, the engagement between the upper locking portion 3 and the upper locked portion 11 (upper engagement) and the lower locking portion 4 are performed. Lower locked part 12
The canopy 6 and the container body 1 are integrated with each other by the engaging force based on both the engagement between (and the lower side), and after the lower portion 9 of the skirt portion 7 is cut off, the two are exclusively due to the upper engaging force. It is one.

Therefore, the upper and lower engaging forces are determined based on their respective roles, and for example, in the case of the upper engaging force, the contents are closer to the contents until the lower portion 9 of the skirt portion 7 is cut off. Based on the design concept, it is necessary to ensure the sealing function at the engaging portion, and to emphasize the sealing function by the upper engagement rather than the ease of detaching the canopy 6 even after the lower portion 9 of the skirt portion 7 is cut off. A relatively strong engagement force will be set.

On the contrary, when prioritizing the ease of removal of the canopy 6 after the lower portion 9 of the skirt portion 7 is cut off, the upper engaging force is set to be relatively weak, and this weakness is supplemented. In this way, the lower engaging force tends to be set relatively strong.

In any case, after the lower portion 9 of the skirt portion 7 is cut off, the lower side engagement is released, so that the engaging force as a whole is weakened from the beginning, so that the canopy 6 is removed from the container body 1. Will be easier than it was initially.

[0047]

According to the present invention, the container body is provided with the upper locking portion and the lower locking portion, and the upper locked portion and the lower locked portion which are engaged with the upper locking portion and the lower locking portion are provided above the skirt portion of the canopy. Since it is provided on each of the lower part that can be cut and cut, the canopy can be firmly attached to the container main body by the engagement of these two points, and the inside of the container main body can be reliably sealed, and the canopy and the container can be shipped at the time of product shipment or transportation. The seal between the main body and the main body can be reliably maintained, and only the engagement between the upper locking part and the upper locked part can be done by a simple procedure such as cutting off the lower part of the skirt, weakening the overall engaging force. By doing so, the canopy can be made removable.

When removing the canopy from the container body,
Since there is no vertical cut in the skirt, it is not easily damaged even when the canopy is greatly curved, and the function of the canopy can be maintained even if the removed canopy is attached to and detached from the container body several times. You can

When the canopy removal operation piece is formed, the user holds the canopy removal operation piece and pulls it up to remove the canopy. The engagement between the locked portions can be released more easily, and the canopy can be easily removed by the user even when the engagement force between the upper locking portion and the upper locked portion is strong.
