Description

[Detailed description of the invention] This invention enables the flat lid to be removed from a container body obtained by forming a laminated resin sheet mainly by vacuum forming without using an adhesive or the like. This relates to a container made of composite resin that can be fitted into and sealed.

Conventionally, a thermoplastic resin sheet is used and vacuum molded to form a box-shaped recess of a desired shape to form a thin-walled container, and the desired articles are placed in the thin-walled container and then separated as needed. A lid made of a material is placed over the edge of the container and closed by heat processing.

Therefore, it is not possible for consumers etc. to close the lid and return it to its original state after confirming the contents of relatively small items.
Therefore, when used to display and sell equipment parts, etc., both the seller and the consumer will experience inconvenience, compared to the previous packaging in containers such as paper boxes.

If the article to be packaged is housed in a paper packaging product, it is not suitable for this purpose because it cannot be made transparent like a plastic box-shaped container so that the appearance of the packaged item can be seen directly.

Therefore, the contents can be identified from the outside in the packaged state, and the user or seller can take out and check the packaged contents as necessary without destroying the packaging container, and when it is no longer needed, it can be returned to the original packaging. A packaging configuration that can be restored to its original condition is desired.

The present invention was developed in view of this situation, and it is possible to check the contents in the packaged state, and also to take out the contents from the container by removing the lid and check the contents, or to check the contents in the packaged state. Although the external appearance of the object cannot be visually checked, the contents can be confirmed by removing the lid, and after confirmation, the lid can be fitted back to the state where it can be packaged and displayed as is, i.e. the lid is fitted into the container. To provide a packaging container whose lid can be removed and closed when necessary without being easily removed.

That is, the present invention provides a means for closing the opening of a container made of Hewei resin, which is shaped mainly by vacuum or mold processing, with a flat lid, and a lid holder of an appropriate width is provided at the inner edge of the opening of the container. The stopper step is shaped, and the lid locking protrusion is bulged inward partially or along the periphery on two opposite sides or the entire periphery of the upper side of the catch step, and the locking step is formed. A locking gap is formed between the protrusion and the upper surface of the lid receiving step, into which the edge of the lid is inserted and engaged, and the lid can be fixed onto the receiving step in the locking gap. In this way, a recess for opening the lid connected to the lid receiving step is provided in the vicinity of or a part of the locking protrusion shape or part thereof.

The lid is made of paperboard or other material that is relatively rigid and has an appropriate thickness, with the product name, other necessary articles, manufacturer's name, etc. displayed on the surface.

Below, the present invention will be described in detail with reference to drawings regarding one embodiment.
The one shown in Figure 1 is the most common single container, in which the container body 1 is formed by vacuum molding a transparent resin sheet such as vinyl chloride resin, and 2 is the flange part. , 3 is a storage box part, and 4 is a lid receiving step formed around the upper part of the storage box part 3, and is formed over the entire circumference with an appropriate width.

Reference numeral 5 denotes locking protrusions, and the ones shown in the figure are protruded inward at two locations on each long side at appropriate intervals, and are provided with an appropriate gap t between them and the lid receiving step 4 as shown in FIG. It is shaped so that it has elasticity and allows the lid to be inserted and removed.

In addition, when the size of the container body 1 is large, the shape or number of the locking protrusions 5 can be increased depending on the size of the container body 1, and they can also be provided on sides other than the two opposing sides in the same manner.

Reference numeral 6 designates a recess into which a tool for removing the lid is inserted, and it is preferably provided at a location where the lifting force is most effectively applied to the lid.

Reference numeral 10 denotes a lid body (see FIGS. 2 and 3), which is made of, for example, paperboard with decorative paper pasted on its surface and a desired print applied thereto, and its external dimensions are the same as those of the lid body of the container body 1. Reception step part 4
Dimensions that approximately match or are slightly smaller are used.

After storing the article A in the container body 1 constructed in this way,
By aligning the lid 10 with the inside of the lid receiving step 4 and pushing it downward, the locking protrusion 5 protruding above the receiving step 4 is formed by vacuum machining. The protrusion 5 is in a swollen state, and the inside is a space communicating with the outside, and the protrusion 5 is softer and more elastic than the whole certain part, so that the protrusion deforms in response to the pressing force. The edge of the lid body 10 is received into the gap 7 on the lower side of the lever, and the locking protrusion 5 is restored by elasticity, so that the lid body 10 is fixed by the locking protrusion 5 and the receiving stepped portion 4. Fixed and closed.

In this state, the lid 10 closes the opening of the container body 1 without floating and fully performs its function as a lid.

To remove the lid from an item packaged in such a state, insert a flat object such as the tip of a screwdriver into the lid opening recess 6 provided in the flange 2 of the container body 1. If the lid body 10 is inserted into the lower edge of the lid body 10 and the lid body 10 is pushed up, the locking protrusion 5 on the side where the recess 6 is provided will act in the opposite direction to that when the lid body is inserted. , one side of the lid 10 is lifted to release the lock, and the lid 10 can be easily removed.

In this way, in the present invention, the locking protrusion is provided on a part of the container by taking advantage of the characteristics of the shape formed by vacuum forming.
A simple packaging container that combines a lid with rigidity and elasticity to create a secure lid when closed, and when the lid needs to be opened, the lid can be removed using tools at hand to take out the contents. can be obtained with a simple structure and can be supplied at low cost, and the above-mentioned conventional problems can now be easily solved.

According to the gist of the present invention, a large number of containers having the structure shown in FIGS. 1 to 3 are made into a series, and a perforation 9 is made in the second part of the flange, and a perforation 9 is made along the perforation. By cutting it out, it can be used as it is as a packaged container for selling over-the-counter products by cutting out the required number of pieces (see Figure 6; the same structural parts as in the previous example are used as is). ).

Further, as another example of the present invention, as shown in FIGS. 4 and 5,
A narrow lid receiving step 4' (which may be wide as appropriate) is provided on the periphery of the opening of the container body 1', and the upper surface of the receiving step 4' and the top surface of the receiving step 4' are provided on two opposing sides. A locking protrusion 5' is formed on the upper side extending inward over almost the entire length with an appropriate gap t, and a recess 6' for opening the lid is formed in the edge 2' on one side. A hanging plate 8 is integrally attached to extend one side of the edge 2' of the main body 1' and attach display paper of appropriate size suitable for exhibition and sales. By using the hanging hole 8', it can be hung for display and sale.

Note that the article A is placed in the storage box part 3' of the container body 1',
Lid body 10 (constructed almost the same as in the above embodiment)
The locking protrusion 5' is compressed and the edge portion is engaged with the gap 7' formed by the locking protrusion 5' and the receiving step portion 4' to be fixed.

In the case of this type, since the locking protrusion 5' extends over the long side, its protrusion amount is kept short within an allowable range, and the locking protrusion 5' is easily deformed when the lid body 10 is fitted into the gap 7. It has a chevron-shaped cross-section so that the lid edge can be engaged within the opening.

Even in such a structure, the same functions as those of the above embodiment can be exhibited and the same effects can be obtained.

Of course, the shape of the container can be determined by vacuum molding, so it can be provided at low cost without increasing manufacturing costs, and it can be made into a convenient and practically effective packaging container for equipment parts, etc. be.

According to the gist of the present invention, it can be used not only in square containers as described above but also in circular containers by providing it at the opening edge of the container, and that it can also be used in any other shape such that it does not sit locally on the lid. Needless to say, it can be adopted as long as it is not a structure.
