TITLE OF THE INVENTION
Package BACKGROUND OF THE INVENTION
Field of the Invention This invention relates to the structure of a small package for 3toring therein a liquid, pa~te-like, powdery or granular content such a~ qeasonings and drinks, cosmetics, chemicals, and ~o forth. More particularly, the prexent invention relates to a package which stores at least one kind of content in itq independent pockets and can dispense the contents simultaneously and easily by pinching and rupturing the package by fingerq of one hand without mixing the contents (.~uch as vinegar and oil, coffee and cream, powdery detergents and powdery bleacher, and the like).
De~cription of the Conventional Art Various small packageq whose content can be taken out easily by a finger-pinching operation have been proposed in the pa~t as typified by the packages of Japanese Patent Laid-Open Nos. 103,866/1984 and 140,973/1986. These packages have the ~tructure in which the peripheral portion of a flexible container member is fixed to the reverse of a :
- 1 - ~
relatively stiff, flat and sheet-like lid to define a pocket, a content i~ sealed in the pocket, a bending line such a~ a perforation is formed on the axis at the center of the lid surface so as to make the lid easily bendable and a projection having a pyramidal shape or a shape of a circular truncated cone is formed at the center of the axis in order to easily dispense the content. In this structure, the content can be dispensed with directivity from a narrow zone such as the projection formed on the lid by pinching the package between fingers and bending the lid in a V-shape in such a manner as to compress the pocket with the axis of the lid being the center.
However, in the conventional packages such as described above, the lower part of the pyramidal or circular truncated conical projection disposed at the center of the lid is used a a communication portion communicating with pockets on both sides. Accordingly, the contents can freely move between these pockets, and the package cannot be u~ed when the content~ must not mix with each other. Mixing of the contents before use deteriorates the appearance or reduces the quality of a product when, for example, two kinds of medicine~ (e.g. powdered medicine and liquid medicine for a patient or peanut butter and strawberry jam to be spread on bread are sealed independen~l ~n the pochets.

:~ 2~`9^"1 SUMMARY OF THE INV~NTION
The present invention i-~ directed to provide the structure of a small package which can eliminate the problem of the conventional art described above, does not mix the different kind~ of contents stored independently in the respective pockets before use and can dispense simultaneously these contents from Yeparate discharge ports by a one-touch operation.
The package in accordance with the present invention is characterized in that it compri~eY a lid having a bending line at the center of its surface and made of a stiff material, and a container member fixed to the reverse of the lid around its peripheral portion, forming pockets on both ~ides of the bending line and made of a flexible material, each of the pockets having a communication portion communicating with one of different portion~ on the bending line of the lid but not communicating with another pocket.
BRIEF DESCRIPTION OF THE DRAWINGS
Fig.l show~ one embodiment of the package in accordance with the pre~ent invention, wherein Fig.l(a) is a perspective view, Fig.l(b) is a sectional view taken along line X - X and Fig.l(c) is a perspective view showing the state of its use.
Fig.2 shows another embodiment of the present ~ 2~ 1 fi invention, wherein Fig.~(a) is a perspective view, Fig.2(b) is a sectional view taken along line Y - Y, Fig.2(c) is a sectional view taken along line Y'- Y' and Fig.2(d) is a perspective view showing the state of its use.
DESCR~PT~ON OF THE PREFERRED EMBODI~IENTS
Hereinafter, the present invention will be described with reference to its embodiments shown in the accompanying drawings.
Fig.1 shows one example (P) of the package in accordance with the present invention. Fig.l(a) shows its appearance, Fig.l(b) does its internal structure and Fig.l(c), the state of its use.
In the drawing, reference numeral 1 represents a flat sheet-like lid which is made of a bendable but stiff material such as a synthetic resin (e.g. polyethylene or polystyrene copolymer) but does not have any projection or the like. A bending line 4 consisting of a perforation is formed along the axi~ at the center of the lid surface.
Reference numeral 5 represents a container member whose peripheral portion i~ fixed to the reverse of the lid 1 and which con~ist~ of a flexible sheet member such as polyethylene or aluminum. The bottom of the container member 5 is recessed greatly in such a manner as to define two pockets 6, 6 having a substantially equal capacity with 1 fi the bending line 4 of the lid 1 being the center, a~ shown in Fig.l(b). The container member 5 has communicat~on portions 7, 7 which, formed when the pockets 6, 6 are formed, communicate separately with those portions which are spaced apart from each other on the reverse of the bending line 4 (hereinafter the portions on the bending line 4 communicating with the communication portions 7, 7 are referred to aY "rupture zone 3). In other words, the lid 1 and the pockets 6, 6 are fixed along the bending line 4 so that rear sides of the rupture zones 3, 3 are fixed alternately on both sides of the bending line 4 as the axis of symmetry and the peripheral portions of the rupture zones 3, 3 are fixed except for the rupture zones 3, 3 which are left unfixed, thereby forming a fixed zone 2. Paste-like different contents A and B are sealed into the pockets 6, 6 of the package (P) having the structure described above by a suitable sealing method, respectively.
Before the package (P) having the structure described above is used, the contents A and B stored in the pockets 6, 6 are æealed completely by the lid 1, the fixed peripheral zone of the container member 5 and its fixed portion along the bending line 4 and cannot therefore move freely between the pocket~. When both ends of the lid 1 are pinched by fingers with the bending line 4 being the center and the lid 1 is bent in a V-shape in such a manner as to attract the pockets 6, 6 to each other, the pockets 6, 6 come into contact with each other and are compressed so that a large load i~ applied to the contents A, B and this internal pressure is as such applied straight to the rupture zones 3, 3 on the bending line 4 consisting of a perforation or the like. Then, the rupture zones 3, 3 are broken and the contents A, B are simultaneously flown from the right and left pockets 6, 6 through the respective communication portions 7, 7 and the respective rupture zones 3, 3 to the outside. In this instance, ~ince the portions near both sides of the bending line other than the rupture zones 3, 3 are fixed in the same way as the fixed zone 2 between the reverse of the lid 1 and the peripheral portion of the container member 5, they are not ruptured even when the internal pressure described above is applied thereto, and the internal pressure acts concentratedly upon the unfixed rupture zone~ 3, 3. Incidentally, the rupture will more easily occur if, in order to facilitate opening, a notch or tongue is formed in advance in the rupture zones 3, 3 on the surfaoe of the lid 1 in addition to the perforation.
Therefore, the content~ A, B can be dispensed easily with directivity from the extremely narrow zone on the lid surface, that is, the rupture zones, 3, 3, by the one-hand operation.
Fig.2 shows another embodiment (Q) of the package in accordance with the present invention. Fig.2(a) shows the appearance of the package, Figs.2(b) and 2(c) do its internal struoture and Fig.2(d) shows the state of its use.
In the drawing, reference numeral 1 represents a lid made of a bendable but stiff material (the definite example of which is the same as that of the package P of the foregoing embodiment; hereinafter the same), and a fixed zone 2' with the open peripheral portion of a container member 5 made of a flexible material (the definite example of the material of which iQ the same as that of the package P of the foregoing embodiment) is disposed on the reverse of this lid 1. The bottom of the container member 5 is recessed greatly in such a manner as to define two pockets 6, 6 having a substantially equal capacity with a bending line 4 of the lid 1 being the oenter, as shown in Figs.2~b) and 2~c). Two pyramidal projections la, la are formed on the bending line of the lid l by recessing its reverse. The projections la, la croQs the bending line 4 at two positions on the center axis of the lid 1 ~not shown), and have tips 3', 3' which are easily ruptured or opened when the lid 1 is bent along the bending line 4. Fixing of the pockets 6, 6 inside the zones along the bending line 4 is the same as in the foregoing embodiment. Therefore, the pockets 6, 6 have their respeotive communication portions 7, 7 communicating with the lower portions of the respective projections la, ,~
`` ' ` :
- ~` `
1 fi la. Paste-like different contents A and B are sealed into the pockets 6, 6 of the structure having the structure described above by a suitable sealing method.
Before the package (Q) having the structure described above i~ u~ed, the content~ A, B stored in the pockets 6, 6 are ~ealed completely by the peripheral fixed zone 2' between the lid 1 and the container member 5 by the fixed portion of the container member 5 along the bending line 4 and cannot therefore move freely between the pockets. To dispense these content~ A, B, the lid 1 is first pinched between fingers in such a manner that the tips 3', 3' of the projections la, la of the lid 1 face downward. Then, when the lid 1 iY bent along the bending line 4 in such a manner as to clamp the right and left pockets 6, 6, both pockets 6, 6 come into contact with each other and are compressed.
Thus, a high load is exerted on the contents A, B and the internal pressure is applied as it is through the oommunication portions 7, 7 to the tip portions 3', 3' of the respective projections la, la on the bending line 4. As a re~ult, rupture occurs on the lid 1 from the tip portions 3', 3' so that the contents A, B are dispensed from the rupture portions, respectively. Therefore, with the package (Q), in the ~ame way as the paokage (P), the contents A, B
can be easily taken out with directivity from the extremely narrow zone of the lid surface, that is, the tips 3', 3' by . : ~
.
1 fi one-hand operation.
As described in detail, the package in aocordance with the present invention does not permit free movement of the contents stored in the respective pockets between them.
Therefore, the present invention can prevent the mixture of the contents or non-uniform existence of the contents in either one of the pockets during storage and transportation of the package before its use. Therefore, the appearance of the package can be improved and different kinds of contents which, although to be used simultaneously, will cause degradation of qual~ty upon mixture, can be sealed qeparately into the same package. Since the contents can be dispensed extremely easily by one-touch operation, the package of the present invention can be used in various fieldq for dispensing drinks, cosmetics, chemicals, and so forth.
