TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a full-open type container that is opened by removing the entire lid from a body.
[0002]
[Prior art]
Generally, this type of full-open type container can be easily opened by removing almost the entire lid by a tab operation, so that it is often used for storing solid or semi-solid foods such as fish meat and prepared foods. Used.
FIG. 6 shows an example of a full-open type container, (a) is a perspective view of the container, and (b) is an enlarged partial cross-section on the S surface of (a) after the lid is opened and the contents are taken out. It is shown.
The full-open type container 30 has a bottomed cylindrical body 31, a full-open type lid 32 attached to one end of the body 31 by winding a peripheral portion thereof, and a part of the lid 32. And a tab 33 formed on the upper surface of the main body.
[0003]
A notch 321 is formed in the lid 32 concentrically with the trunk 31. By operating the tab 33, the lid 32 is separated from the trunk 31 at the cut 321 and is opened. It has become.
In addition, as for such a full-open can open structure, for example, “Can lid and its manufacturing method” in Patent Document 1 and “Fizzy beverage can and its manufacturing method” in Patent Document 2 are known. .

[Patent Document 1]
JP 2001-31087 A [Patent Document 2]
JP 2001-180671 A
However, the conventional containers described in the above patent documents have the following problems.
That is, there is a problem in that when the paste-like content having high adhesiveness is opened and taken out, the content sticks to the inner peripheral wall or the bottom of the body, and the content cannot be easily taken out.
As shown in FIG. 6B, when the lid 32 is cut off from the body 31 at the cut 321, the opening edge after the removal of the lid 32 projects from the inner peripheral wall of the body 31. When forming the portion 312a and taking out the slurry-like or paste-like content M, there is a problem that the content M tends to remain inside the overhanging portion 312a. Furthermore, there is a problem that it is difficult to remove the contents M remaining between the overhang portion 312a and the inner peripheral wall of the body portion 31 because the overhang portion 312a is in the way.
[0006]
In addition, since the lid 32 is cut off from the trunk 31 at the cut 321, once the lid is opened, the lid 32 cannot be attached to the trunk 31 again, and the container 30 cannot be reused. .
Furthermore, when the container 30 is discarded after the contents are taken out, the bottom cover integrated with the body 31 hinders the container 30 from being crushed, and there is a problem that the container 30 becomes bulky at the time of disposal.
In addition, as shown in FIG. 6B, there is a problem that the periphery of the overhang portion 321 becomes edge-shaped after the lid is opened, and it is dangerous to insert the hand inside the container 30 and take out the contents.
[0007]
In addition, in consideration of safety when the operator inserts his / her hand into the inside of the container and removes the contents after removing the lid portion, there is a case in which the periphery of the overhang portion has a rounded edge ( For example, see Patent Document 3).
[0008]
[Patent Document 3]
JP-A-9-39963
In the container described in Patent Document 3, at a position close to the canopy of the trunk, the trunk wall of the trunk is protruded toward the center of the can, and is crushed and overlapped to obtain a score (cut). A ridge projecting more toward the center of the body than the body wall is formed around the body wall.
Therefore, there is a problem that the processing steps are complicated and the manufacturing cost of the container is increased. Also, this container cannot solve the other problems described above.
[0010]
[Problems to be solved by the invention]
The present invention has been proposed in order to solve such problems of the conventional technology, and it is easy to open the lid and take out the contents, can be used repeatedly as a container, and can be disposed of. It is an object of the present invention to provide a container which can be manufactured at a low cost, in which the processing of the container at the time of opening is easy and the safety of the periphery of the opening can be enhanced after the lid is opened.
[0011]
[Means for Solving the Problems]
In order to achieve the above object, the inventors of the present invention have conducted intensive research, and as a result, formed openings at both ends of the body, and covered at least one of the openings with an openable and closable lid. I thought I could achieve my goal.
[0012]
That is, the double-ended container according to claim 1 is a full-open type container that is opened by removing the entire lid from the body, and has openings at both ends of the body, and at least the body. A hook portion is formed outside the periphery of one of the openings, and a lid is hooked on the hook portion to seal.
According to this configuration, since openings are formed at both ends of the body portion, it is easy to take out even highly adhesive contents such as paste-like contents.
In addition, since the latching portion for latching the lid is formed outside the peripheral edge of the opening, it is possible to eliminate the projecting portion from the inner peripheral wall of the trunk, and it is possible to take out all without leaving the contents Become. Further, it is possible to secure safety when the contents are taken out by inserting a hand into the inside of the container.
In addition, since both ends of the body are open, the body is easily crushed at the time of disposal, and the container can be discarded without being bulky.
[0013]
It is preferable that at least one of the lids is a royal cap, and a latch portion for latching the latched portion of the royal cap is formed around at least one opening edge of the body. Further, in this case, it is preferable that the periphery of the opening is folded back to the outside of the body to form the annular hook portion.
The royal cap can be easily opened with one hand by pressing substantially the center of the top surface. In addition, since the royal cap can be used repeatedly, the container can be reused.
Furthermore, by covering the royal cap on both openings of the body, it is possible to simultaneously open both ends of the container with one hand.
[0014]
Further, a sealing member for sealing may be interposed between the lid and the body.
When a royal cap is used as the lid, considerable resilience can be expected due to its elasticity.However, by interposing such a sealing seal, it is possible to further enhance the sealing performance of the container. it can.
[0015]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, a preferred embodiment of a double-ended container according to the present invention will be described with reference to the drawings.

FIG. 1 is an exploded perspective view of a double-sided container according to a first embodiment of the present invention, and FIG. 2 is a partially enlarged cross-sectional view of a main part of the double-sided container, showing a locked state of a lid and a body. FIGS. 3A and 3B are diagrams illustrating the operation of the double-ended container according to this embodiment. FIG. 3A illustrates a closed state, FIG. 3B illustrates an opened state, and FIG. It is a figure explaining the use method of the container which has both ends open of an embodiment.
[0016]
The open-ended container 10 has a cylindrical body 11 having an upper opening 111 and a bottom opening 112 formed at both ends, a royal cap 12 which is covered by one end of the body 11, and serves as an upper lid for sealing the upper opening 111. And a royal cap 13 which is covered by the other end of the body 11 and seals the bottom opening 112 as a bottom lid.
The body 11 may be formed of a metal thin plate and may be formed into a cylindrical shape by welding both ends, or may be formed by drawing a metal thin plate into a cylindrical shape.
[0017]
At both ends of the body 11, annular hooks 113 for hooking the royal caps 12 and 13 by bending the entire periphery of the periphery of the upper opening 111 and the periphery of the bottom opening 112 of the body 11, 114 are formed.
As shown in FIG. 2, lower ends 113 a of the hooks 113, 114 hook hooks 122, 132 formed at equal intervals around the top surfaces 121, 131 of the royal caps 12, 13. The upper ends 113b of the hooks 113, 114 are in close contact with the body 11 together with the top surfaces 121, 131 of the royal caps 12, 13, and are formed as portions for keeping the open-ended container 10 in a sealed state. ing.
[0018]
The hooks 113 and 114 can be formed using a known technique such as press molding. Although not shown, an annular or sheet-shaped sealing member may be interposed between the peripheral edge of the opening of the body 11 and the royal caps 12 and 13 in order to enhance the sealed state of the container 10 with both ends open.
[0019]
In this embodiment, as described above, the royal caps 12 and 13 are used as lids. The royal caps 12 and 13 are advantageous in that they can be opened with a single touch and can maintain a high sealing property by their elasticity.
The royal caps 12 and 13 include top surfaces 121 and 131 for sealing the upper opening 111 and the bottom opening 112 of the body 11, and a plurality of hooks 122 and 132 formed around the top surfaces 121 and 131. It is composed of
As shown in FIG. 3, the royal caps 12 and 13 have bulges at the centers of the top surfaces 121 and 131, and a convex state (a state shown in FIG. 3A) by applying a pressing force to the centers. And a concave state (a state shown in FIG. 3B). Then, with this deformation, the lower ends of the hooked portions 122 and 132 open and close in the radial direction.
[0020]
That is, when the top surfaces 121 and 131 of the royal caps 12 and 13 are in a convex state, the lower ends of the hooked portions 122 and 132 are closed in the radial direction, and the hooking portions 113 and 114 of the body 11 are closed. The lower end and the hooked portions 122 and 132 are in a hooked state, and the top surfaces 121 and 131 are pressed against the opening periphery of the body 11. When the top surfaces 121 and 131 of the royal caps 12 and 13 are in a concave state, the lower ends of the hooks 122 and 132 are opened in the radial direction, and the lower ends of the hooks 113 and 114 of the body 11 are closed. The engagement with the engaging portions 122 and 132 is released, and the royal caps 12 and 13 can be removed.
[0021]
FIG. 4 is a view for explaining a method of opening the royal caps 12, 13 of the double-ended container 10 having the above configuration.
The double-ended container 10 of the present invention can be opened with only one hand H. As shown in the figure, a pressing force is simultaneously applied to the top surface 121 of the royal cap 12 and the top surface 131 of the royal cap 13 by sandwiching the top and bottom of the double-sided container 10 between the thumb and another finger. As a result, the top surfaces 121 and 131 are deformed from the convex state to the concave state, and the lower ends of the hooks 122 and 132 are opened in the radial direction, so that the hooks 122 and 132 and the hooks 113 and 114 are Is released (see FIG. 3). Therefore, the royal caps 12 and 13 can be opened, and the contents can be taken out.
[0022]
In the double-ended container 10 of this embodiment, since there is no protrusion such as a projecting portion on the inner peripheral wall of the body 11, and both ends (the upper opening 111 and the bottom opening 112) of the body 11 are simultaneously opened. All of the contents can be easily taken out. In addition, after the lid is opened, the peripheral edges of the upper opening 111 and the bottom opening 112 do not become edge-shaped, so that safety when inserting a hand and performing work can be ensured.
[0023]
Furthermore, by returning the top surfaces 121 and 131 of the royal caps 12 and 13 to the original convex state and covering the both ends of the body 11, it is possible to reuse the double-sided container 10. Therefore, the body part 11 and the royal caps 12 and 13 can be collected by the manufacturer and reused as the double-ended container 10 again, so that the resources can be effectively used.
In addition, the cylindrical body 11 having both open ends can be easily crushed and does not become bulky when the container is discarded.
[0024]
The royal caps 12 and 13 may be of the same type, or may have different pressing forces for deforming from a convex state to a concave state. By doing so, it is possible to open only the other (for example, the royal cap 12) while maintaining the closed state of one (for example, the royal cap 13).
In addition, the double-ended container 10 having the above-described configuration is suitable for storing solid or semi-solid contents, but in particular, slurry or paste-like contents such as tuna, corned beef, pet food, mousse, etc. It is also suitable for storing non-food items such as wax, grease, paint, etc., in addition to the above-mentioned food items.
