CONTAINER WITH A CATCH FOR PRESSING AND OPENING A LID
An important object of the present invention is to provide a container the contents of which can be easily 5 removed from the inner case by pressing and pushing the top of the quadrilateral hollow three-dimensional body at the right end of the inner case and by taking the inner case out of the outer case.
Another object of the present invention is to provide 10 a container which is capable of holding rather long and fragile articles such as ampules for injection and safely retaining them without allowing them to come into contact with each other and break.
Still another object of the present invention is to pro- 15 vide a container which is capable of displaying its contents in shop windows when its inner case is allowed to be partially removed from the outer case.
Still a further object of the present invention is to provide a container which is capable of being manufac- 20 tured by machinery on a mass production basis with a marked decrease in the number of cumbersome pasting processes in assembling it.
In order to make containers for holding long and fragile articles such as ampules, it has hitherto been 25 necessary for one to provide the body of a case with no top, to provide a partition therein for insertion of the contents and to provide a lid on the top. In making such containers, various delicate operations such as pasting the body and the lid, the formation of the body and of 30 the partition, and the insertion and adjustment of those things are required. Thus, they are unsuitable for mass production by machinery.
What is more, such containers have a complicated construction and are very expensive. Besides, it has a 35 further defect in that it is difficult to insert or withdraw such contents as ampules.
On the other hand, the containers of the present invention are not only suitable for mass production at low cost in simple mechanical manufacturing processes, but are also capable of safely retaining fragile and long articles.
The present invention will now be described in detail by way of example with reference to the accompanying drawings in which:
FIG. 1 is a perspective view of the container as a whole.
FIG. 2 is a perspective view of the inner case. The letter A indicates a basic type and B a variation thereof. 5Q
FIG. 3 is a perspective view of the inner case of the basic type with the contents held therein.
FIG. 4 is a perspective view of the container with its lid open, its inner case being of the basic type. 55
FIG. S is a center longitudinal sectional view of the inner case. The letter A indicates a basic type and B a variation thereof.
FIG. 6 is an expansion view of the inner case. The letter A indicates a basic type and B a variation thereof. 6Q
FIG. 7 is an expansion view of the outer case.
Referring now to the drawings and specifically to FIGS. 1,2,5 and 6 the letter X designates an inner case. Outer front and back walls 3 and 3' are integrally con- 65 nected at fold lines 2 and 2' on the front and back of the base plate 1 of the said inner case X to the base plate 1. Inner front and back walls 5 and 5', which are
slightly narrower than the outer front and back walls, are integrally connected at fold lines 4 and 4' to the outer front and back walls. In the middle of the edges of the inner front and back walls 5 and 5' are provided slits 6 and 6', which are twice as high as the thickness of the material for the inner case. A left side wall 8 is integrally connected at a fold line 7 to the left edge of the base plate 1. There is also integrally formed a slanting left side wall 13 having any number of cut-off portions 11 and 12 for partition having fold lines 11' and 12'. Side wall 13 is made slightly narrower than the width of the base plate 1 by allowing both side edges TO and 10' of the wall 13 to be cut off from a fold line 9. An inner case left portion fixing wall 15 is integrally connected to the edge of the slanting left side wall 13 at a fold line 14, the wall 15 being approximately as wide as the base plate 1. A right side wall 17 is integrally connected to the right end of the base plate 1 at a fold line 16. To the right side wall 17 are integrally connected a lid 21 and an inner lid 22 in turn, the widths of which are made narrower than that of the base plate 1 by allowing their both side edges 20 and 20' to be cut at fold lines 18 and 19 in turn.
Extending through said lid 21 to said inner lid 22 are provided fold lines 23' and 24' which form cut-off portions 23 and 24 corresponding in number to the number of cut-off portions 11 and 12 of the slanting left side wall 13. To the right edge of the inner lid 22 is integrally connected an inner case lid fixing wall 26 at a fold line 25, the wall 26 being approximately as wide as the base plate 1.
The assembling of the inner case is just as has been described above. The outer front and back walls 3 and 3' are allowed to rise and bend at the fold lines 2 and 2'. The fold lines 7,9, and 14 are bent and then the lugs 27 and 27' of an inner case left portion fixing wall 15 are inserted into and fixed in the slits 6 and 6' cut in the inner front and back walls 5 and 5' folded along the inside of the outer front and back walls 3 and 3' at the fold lines 4 and 4'. Similarly, the fold lines 18; 19 and 25 are folded to form a quadrilateral hollow threedimensional body, and then lugs 28 and 28' on both sides of an inner case lid fixing wall 26 are inserted into and fixed in said slits 6 and 6' to form the inner case X with its top open.
Next, referring to FIGS. 1, 2, 3'A, 4, 5A, and 6, an outer case Y is constructed as follows: A cut-off portion 30 is provided at the right edge of an upper wall 29, and a pasting portion 31 of front and back walls is pasted; and the right side is opened while the remaining five sides are closed to form the outer case Y. Then, the inner case X is slidably inserted into the outer case Y. Since any desired number of cut-off portions 11 and 12, and 23 and 24 are provided at corresponding locations on the slanting left side wall 13, and the lid 21 and the inner lid 22; the contents such as a pair of injection bottles or of ink eraser bottles, as shown in FIG. 3, will not be damaged by colliding with each other in transit.
In opening the lid, just push and press the lid 21 appearing in an arched shape under the cut-off portion 30 at the right edge of the upper wall 29 of the outer case X, as shown in FIG. 1, with a finger until it becomes more or less flat, and slide the inner case X out of the outer case Y. Thus, the contents can be removed by a simple oprations.
