Description

[Detailed Description of the Invention] [Technical Field] The present invention mainly relates to a small capacity extrusion container.

[Background Art] Conventionally, as a disposable small-capacity container, a structure in which a top film is attached to a base having a recess for storing contents and the recess is sealed is known. The recess for storing contents is rectangular parallelepiped (1986-36626, 52-28709,
52-38550, 52-38551, 54-9579, Jitsukaiaki
51-78873, 54-81876), or the bottom wall of the content storage recess is simply inclined at a uniform angle so that the cross-sectional shape of the recess is triangular (Utility Model No. 58- 15416) etc. Therefore,
When attempting to push out the contents in the concave portion by providing a discharge port in the concave portion for storing contents of such conventional structure and crushing the concave portion, the concave portion for contents storing is difficult to be crushed; There was a problem in that the contents tended to remain in the recesses after extrusion.

[Purpose of the invention] An object of the invention is to provide an extruded container that is easy to crush and in which the contents do not easily remain.

[Structure of the invention] Therefore, in the present invention, a top film is pasted on a base body having a concave part for storing contents in which a narrow part for forming an ejection port is connected, the recess is sealed, and the narrow part for forming an ejection port is formed. In an extrusion container in which the contents in the recess are extruded from the discharge port when the recess is crushed, the bottom wall of the content storage recess is relatively moved closer to the top film as it moves away from the narrow part for forming the ejection port. In addition to gently inclining the bottom wall, a vertical wall opposite to the narrow portion following the bottom wall is relatively steeply inclining in the same direction as the bottom wall, so that the content storage recess is easily crushed and pressed. When crushed, it is easy to flatten without any gaps, and
When crushed, the contents are easily pushed out toward the discharge port to achieve the above object.

[Description of Embodiments] Hereinafter, embodiments of the present invention will be described based on the drawings.

1 to 3 show an embodiment of the extrusion container according to the present invention. In the figure, a recess 2 for storing contents (see FIG. 3) is formed in a base 1 by vacuum-pressure forming, etc., and a recess 2 for storing contents 2 is inserted into the recess 2 through a seal 3 at a flange portion of the base. 1
A top film 4 is attached to the top film 4, thereby sealing the content storage recess 2 (content 5 in the recess 2).

Here, the base body 1 and the top film 4 are made of mutually different or the same synthetic resin materials, and examples of the synthetic resin materials include polystyrene, polypropylene, polyethylene, polyvinyl chloride, polyacrylonitrile, and the like. If 5 is a food product that dislikes oxidation or water vapor, polypropylene/ethylene-vinyl acetate copolymer saponified product/polypropylene, polystyrene/ethylene- These include a laminate film of saponified acetic acid copolymer/polypropylene, polypropylene/polyvinylidene chloride/polyethylene, or a laminate of aluminum foil and synthetic resin material.

In addition, contents 5 include mayonnaise, mustard paste, jam, margarine, butter, cream, mousse,
Food products such as ketchup, toothpaste cosmetic creams, pharmaceutical creams, paints, paints, and other non-food products, especially viscous fluids with relatively low viscosity.

A narrow width part 6 for forming a discharge is connected to one end side of the recess 2 for storing contents, and a recess 7 for gripping is further connected to the narrow width part 6 for forming a discharge. A notch 8 (see Fig. 2) is formed near the forming narrow part 6, and by pinching the picking recess 7 and tearing or twisting it off from the notch 8, the content storage recess is formed. A discharge port 9 (see FIGS. 4 and 5) can be easily formed at one end of the tube 2. Further, as shown in FIG. 2, the content storage recess 2 is formed so that it becomes wider as it moves away from the discharge forming narrow width part 6. In other words, the content storage recess 2 The width is gradually narrowed toward the narrow width portion 6 for discharge formation.

Bottom wall 2 forming the bottom of the content storage recess 2
A is inclined relatively gently (for example, X = about 10 degrees in FIG. 3) so that it approaches the top film 4 as it moves away from the content storage recess 2, and the narrow width for forming the discharge continues from the bottom wall 2A. The standing wall 2B on the opposite side of the section 6 is inclined relatively sharply (for example, Y = 20 to 40 degrees) in the same direction as the bottom wall 2A, and the boundary between the bottom wall 2A and the standing wall 2B is a corner 2C. ing. Further, the vertical wall 2D of the bottom wall 2A on the side of the narrow width part 6 for discharge formation is inclined so as to approach the top film 4 as it approaches the narrow width part 6 for discharge formation from the bottom wall 2A, and the state of the inclination is not particularly limited. The angle may be 90 degrees with respect to the film 4, but in other cases, the angle may be the same as that of the vertical wall 2B, and the vertical wall 2D may be formed in a substantially funnel shape to facilitate squeezing out the contents 5. are doing. Further, the standing walls 2E on both sides of the bottom wall 2A are not particularly limited, but for example, the contents storage recess 2
It is tilted towards the center.

Next, how to use this embodiment will be explained with reference to FIGS. 4 and 5.

After forming the discharge port 9 by an appropriate method, as shown in FIG. 22's abdomen is pressed against the corner 2C. From this state, as shown in FIG. 4B, use the thumb 22 to press the corner 2C.
When the concave part 2 is pressed so as to crush it, the concave part 2
is crushed, and the contents 5 corresponding to the internal capacity of the crushed recess 2 are pushed out from the discharge port 9, and the tip side of the thumb 22 is also squeezed out of the top film as shown in FIG. 4C. 4 side to flatten the entire bottom wall 2A, most of the contents 5 will be extruded from the discharge port 9.

Next, I will explain how to use it other than the above.
As shown in FIG. 5A, place the thumb 22 on the top film 4 side and place the index finger 21 on the bottom wall 2.
As shown in FIG. 5B, it can also be used by pressing the approximate center of the bottom wall 2A with the index finger 21 to crush the entire content storage recess 2. It's good.

This embodiment has the following effects.

Since the standing walls 2B, 2D, and 2E are inclined, if the standing walls 2B, 2D, and 2E are 90 degrees (perpendicular) to the top film 4, the reaction force upon pressing will be large, but unlike this, The reaction force when pressing the bottom wall 2A is small, and the recess 2 for storing contents
Easy to crush.

Further, as the bottom wall 2A and the vertical wall 2B move away from the discharge forming narrow part 6, the top film 4
, so that when the contents storage recess 2 is crushed, the contents 5 in the recess 2A are pushed toward the discharge port 9 side, and the contents 5 are naturally pushed out from the discharge port 9. It will be put away.
Therefore, in addition to being easy to crush, there is an effect that the contents 5 are easy to extrude.

Furthermore, the bottom wall 2A and the standing wall 2B are not sloped uniformly as a whole, but are configured to be continuous from the relatively gently sloped bottom wall 2A to the relatively steeply sloped standing wall 2B. Therefore, if the corner 2C constituting this boundary is crushed, the corner 2C will be inverted (turned inside out) by the pressure of the thumb 22, as shown in FIG. 4B mentioned above. the corner portion 2C)
is pressed against the top film 4, and the contents 5 do not remain on the hand side. Therefore, there is an effect that the contents 5 are easily extruded from the discharge port 9 and are less likely to remain.

In addition, since the bottom wall 2A and the vertical wall 2B have such inclination angles, there is an effect that the capacity of the content storage recess 2 can be easily made sufficient while making the overall length relatively short.

Here, one specific example is as follows.

Substrate 1...polypropylene/saponified ethylene-vinyl acetate copolymer/polypropylene laminate sheet, thickness 0.3 mm Top film 4...uniaxially oriented polypropylene/
Saponified ethylene-vinyl acetate copolymer/uniaxially oriented polypropylene, thickness 100μm Contents 5...Screw tooth brushing, recess for storing contents 2
...Approximately 5 c.c., total length of the recess 2 for storing contents (see Fig. 3 T)...
50mm Height of recess 2 for storing contents (see Figure 3 H)...
10mm, inclination angle of bottom wall 2A (see X in Figure 3)...10
Degree: Angle of inclination of the vertical wall 2B (see Y in Fig. 3)...40 degrees In such a specific example, most of the contents 5 can be pushed out through the discharge port by just one extrusion operation without changing the grip of the index finger 21 and thumb 22. 9 could be easily extruded.

In addition, in the implementation, the content storage recess 2 had a shape that was gradually narrowed toward the discharge forming narrow part 6, but the shape is not limited to this. however,
When the width is gradually narrowed toward the discharge forming narrow part 6, since the content storage recess 2 is crushed from the vertical wall 2B side, the content 5 can be easily extruded from the formed discharge port 9, and the content can remain. It has the effect of having fewer things. Furthermore, when forming the discharge port 9,
This is not limited to the case where the side of the knob recess 7 is separated from the notch 8. For example, the top film 4 is formed to be relatively hard compared to the base 1, and a narrow width for discharge formation is formed at an appropriate position of the hard top film 4. A cut line is formed at a predetermined depth (however, the top film 4 is not completely separated) across the portion 6, and the top film 4 is folded from this cut line to form the discharge port 9. may be done. In this case, the base 1
The content storage recess 2 and the knob recess 7 do not need to be separated.

[Effects of the Invention] As described above, according to the present invention, it is possible to provide an extruded container that is easy to crush and in which the contents do not easily remain.
