Description

  The present invention relates to a structure that can be easily opened when a lid of a packaging container, which is a resin sheet molded product, and a container body are closed.

  The structure of the container body and lid made of resin sheet molding varies depending on the contents, but in the case of an inner fitting container or an outer fitting container with a sealed structure used when storing food with savory food Since the container body and the lid are tightly closed, it may be difficult for the food purchaser to easily open the lid. Therefore, a structure that can be easily opened even with this type of container has been proposed.

  For example, a configuration is known in which a tongue piece having a shape projecting outward in the horizontal direction is formed on a part of each of the container body and the lid body, and the tongue piece is picked with fingers of both hands and opened to be peeled off. However, when the packaging container has a circular shape, the container body and the lid can be fitted at any position, while the two tongue pieces are preferably positioned in an appropriate correspondence. However, when closing the lid after storing the contents in a backyard such as a supermarket, the lid must be closed while paying attention to the relationship between the tongue pieces, and it is troublesome when processing a large amount of products. there were.

  Therefore, as described in Patent Document 1, a recess 14 is provided in a part of the peripheral surface of the container body, and a knob piece 23 in a form protruding outward in the horizontal direction is formed in a part of the lid corresponding thereto, There is an invention in which a knob piece is accommodated in a concave portion with the lid closed, and the lid is opened by pinching the knob piece with a finger and pulling it up when the lid is opened. Further, in the invention described in Patent Document 2, tongue pieces protrude from the corners of the container main body and the lid in a partially overlapping state, and each tongue piece is picked separately when the lid is opened. A simplified configuration is described.

  However, in the configuration described in Patent Document 1, since the knob piece protrudes from the container body when the lid is closed, if clothes or the like are caught on the knob piece during transportation, the lid may be opened carelessly. is there. Further, since the knob pieces are easily caught even if the lid is not opened, there is a possibility that an accident may occur in which a hand or the like hits the knob pieces and drops the goods on the floor when the goods are stacked. On the other hand, in the invention described in Patent Document 2, each tongue piece protrudes outward, and the tongue piece of the lid is configured to be caught independently, so that the lid is also inadvertently opened. There is a risk.

  The present invention solves such a conventional problem, and a packaging container having an opening structure capable of easily operating a lid body when opening the lid and preventing inadvertent opening. It is intended to provide.

In order to achieve the above-described object, the present invention is a packaging container comprising a container body and a lid, and a knob portion that bulges outward from a part of the outer periphery of the lid is formed. A receiving piece corresponding to the knob portion bulges through a connecting portion on a part of the outer periphery of the container body, and the receiving piece extends along the connecting portion so that the knob portion can be sandwiched between fingers. A means that can be deformed and has an outer periphery larger than the outer periphery of the knob portion is employed. According to this means, since the knob portion formed on the lid body does not protrude outside than the receiving piece formed on the container body , the lid is inadvertently touched and opened by the finger. There is nothing. That is, the receiving piece protects the knob portion in a normal state. Moreover, so as to receive pieces deformed along the connecting portion, so that the tip portion of the knob portion by deforming under direction is detached from the receiving piece which in the case of forming the receiving member to the container body Acts and makes it easy to pinch the knob.

Furthermore, the shape of the knob portion was a flat shape. The knob part is only used for opening the lid, but when it is flat, it is easy to be sandwiched between two fingers.

The receiving piece has a flat surface corresponding to the knob portion and an outer peripheral portion of the flat surface on the tip side excluding the connecting portion, which is higher than the thickness of the knob portion , and is closed. Means for forming a protruding portion for accommodating the knob portion inside at a low position where the finger does not touch the periphery of the knob portion was used. Since the protruding portion is higher than the knob portion, the protruding portion is further protected in a state in which the knob portion is accommodated, and at the same time, the peripheral edge of the knob portion is prevented from inadvertently touching a finger or the like. In addition, when a container that does not have a protruding portion is displayed, the knobs of adjacent containers may interfere with each other, and one knob may sink under the other knob. Inadvertent opening may be made as described above. However, the inconvenience can be avoided by providing a protruding portion.

A large number of fine irregularities are formed on one or both of the flat surface of the knob portion and the flat surface corresponding to the knob portion of the receiving piece to avoid sticking to each other and to avoid slipping when pinched with fingers. .

  According to the present invention, when the lid body is closed with respect to the container body, the knob portion is covered with the receiving piece, so that the knob portion is not inadvertently caught by a finger, clothes, etc. Can now be prevented.

Sectional drawing which shows one Embodiment which piled up the container main body and cover body of the packaging container of this invention. The perspective view which shows the state which closed the container main body and the cover body similarly. The perspective view which shows the knob part provided in the cover body similarly. The perspective view which shows the receiving part provided in the container main body.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a cross-sectional view of an essential part showing a state in which a lid 2 is closed with respect to a container main body 1 of a packaging container showing an embodiment of the present invention. The container main body 1 and the lid 2 are externally fitted. Closed. A flange surface 4 is formed on the outer peripheral portion 3 of the container body 1 in a circumferential shape, and a peripheral wall 5 rises from the flange surface 4 in a substantially vertical direction. Reference numeral 6 denotes a fitting receiving surface formed in an inward ring shape in the middle of the peripheral wall 5. A receiving piece 8 bulges from a part of the lower surface of the peripheral wall 5 via an arc-shaped connecting portion 7. Further, the protruding portion 9 seen on the distal end side of the receiving piece 8 is formed so as to surround the periphery of the receiving piece 8 except for the outer periphery of the container body 1. On the other hand, a flange portion 10 corresponding to the flange surface 4 of the container body 1 is also formed on the lid body 2, and an annular fitting convex portion 12 is formed on the wall surface 11 facing downward from the flange portion 10. The fitting convex portion 12 of the lid 2 is configured to be externally fitted to the receiving surface 6. Reference numeral 13 denotes a knob that bulges outward from a part of the outer periphery of the lid 2 and is accommodated inside the protruding portion 9 of the receiving piece 8 of the container body 1 when the lid is closed. Reference numeral 14 denotes a large number of fine irregularities provided on the surface of the knob portion 13 as appropriate. The height of the protruding portion 9 is set to be higher than the thickness of the knob portion 13. If it does in this way, the knob part 13 will not protrude from the protrusion part 9, and a finger | toe etc. will not be caught carelessly.

FIG. 2 shows a state in which the knob portion 13 formed on the lid body 2 is accommodated with respect to the receiving piece 8 formed on the container body 1 when the lid is closed, and the same numbers as those in FIG. Yes. In this embodiment, the shape of the entire container is circular in plan view. However, the shape of the entire container is not limited to a circle, and may be a rectangle, an ellipse, or a polygon such as a hexagon or an octagon. It does not affect.

  In the packaging container thus configured, when closing the lid, the lid body 2 corresponds to the container body 1, and the knob portion 13 of the lid body 2 corresponds to the receiving piece 8 of the container body 1. At the rotational position, the lid is closed in the same manner as a normal outer fitting container. Once the lid is closed, the knob portion 13 is accommodated in a position lower than the protruding portion 9 formed around the receiving piece 8, so that the knob portion 13 is It wo n’t catch you. Next, when the lid is opened, when a downward force is first applied to a part of the receiving piece 8 of the container body 1, preferably the tip of the projecting portion 9, the receiving piece 8 can be easily connected via the connecting portion 7. Deforms to bend downward. If it does so, the knob part 13 of the cover body 2 will detach | leave relatively from the receiving piece 8, and it can pinch the knob part 13 with a finger | toe. Next, the knob 13 can be secured with the fingers of one hand, the receiving piece 8 can be secured with the fingers of the other hand, and the lids can be easily opened by pulling them apart in the opening direction.

In the present embodiment, the container body 1 and the lid body 2 have been described as being configured to be closed by external fitting. However, the fitting structure is not particularly limited, and may be internal fitting or internal / external fitting. The basic structure can be widely adopted as long as it can be formed by expanding the receiving piece 8 from the outer periphery of the container body 1 and can be formed by expanding the knob 13 from the outer periphery of the lid 2. Of course you can. In addition, the receiving piece 8 formed on the container body 1 is formed through the connecting portion 7 to facilitate deformation. However, if the receiving piece 8 can be deformed downward with a small force, the connecting portion 8 7 may be omitted. In addition, an essential configuration in the present invention is that the knob portion 13 does not protrude from the outer periphery of the receiving piece 8, so that it is not necessary to make the outer shape of the knob portion 13 and the outer shape of the receiving piece 8 similar to each other. The shape portion 9 may be omitted as necessary .

The knob portion 13 and the receiving piece 8 are appropriately provided with a large number of fine irregularities. However, when a water droplet or the like enters between the knob portion 13 and the receiving piece 8, both of them closely stick to each other with the water droplet. However, the unevenness may be omitted if molding is performed so as to form a gap between the knob portion 13 and the receiving piece 8, for example. However, it is preferable to provide unevenness when anti-slip is expected when picked with a finger . The shape of the unevenness is not particularly limited, but may be any shape that can exhibit its function, such as a knurled shape, a dot shape, and a large number of stripe shapes.

  By the way, as shown in FIG. 2 and FIG. 4, in this embodiment, the both end receiving pieces 8 of the projecting portion 9 continue to incline gradually downward. In such a configuration, even when the positions of the container main body 1 and the lid body 2 are shifted during the closing operation, the knob body 13 is rotated with respect to each other to adjust the knob portion 13 to the exact position of the receiving piece 8. Can be rotated smoothly. In other words, once the alignment is performed, the knob portion 13 is regulated by the inner wall of the protruding portion 9, so that even if a force in the rotational direction is applied, the knob portion 13 does not rotate carelessly. However, these relationships function in the case where the fitting portion between the container body 1 and the lid body 2 has a circular shape that fits at any angle in the rotation direction.
