Abstract
An envelope of plastic material (1) comprises a profile (2) being provided
with pressure-closing members (4, 5) and sealed in the upper part of a face (6) of
the envelope; and a free profile (3) being provided with pressure-closing members
(4, 5) to be engaged in closing members of profile (2) and sealable at the upper
part of the other inner surface (7) of the envelope after filling of the same.
Description
- The present invention relates to an envelope of plastic material suitable for being filled with different solid and liquid products, and sealed. As it is known, it is a matter of preformed envelopes made from a roll of plastic film having an open side for the filling and being resealable once the sealing is broken through known plastic pressure profiles. In the field of the filling technique of plastic envelopes, it is known that these comprise internal sides joined together in their upper part wherein the filling takes place, by male and female pressure-closing members, so that the filling of the envelope is accomplished by moving apart said members. This operation has however the drawback that the automatic filling machines encounter serious difficulties in opening the envelopes in the product introducing step.
- As a matter of fact, this opening procedure with the moving apart of said members is hardly solvable but by means of mechanic-pneumatic systems that may even spoil the outer surface of the envelope itself and not correctly work with the discharge of the product.
- The object of the present invention is to eliminate the above mentioned drawbacks, by making an envelope with the new features as described in detail hereafter and illustrated in the attached drawings, wherein:
- FIGURES 1 and 2 show respectively the scheme of an envelope of the prior art in the filling and sealing step;
- FIGURES 3 and 4 show respectively the scheme of an envelope according to the present invention in the filling and sealing step;
- FIGURE 5 shows a vertical sectional view of the upper part of the envelope according to the present invention; and
- FIGURE 6 shows a horizontal sectional view along line IV-IV of the envelope of figure 5, in a reduced scale.
-
- Referring to the schematically shown figures 1 and 2, an
envelope 1 according to the prior art, with a closed bottom not shown in the figures, has twoprofiles 2 and 3 provided with male and female pressure-closingjoint members members members - According to figures 3, 4, 5, 6 of the present invention, in
envelope 1 with the internal sides 6 and 7, only profile 2 is sealed to the internal side of the envelope, while theother profile 3 is free and fixed to profile 2 by means of male andfemale members profile 3 has the ends 3' fixed at the ends of profile 2 at the intersection points of sides 6 and 7 of the envelope. - For filling the product into the envelope, according to arrow A, the envelope is easily open without any difficulty by means of suction cups and pliers 8, since side 7 is free and
profiles 2 and 3 are fixed each other. - After filling, the envelopes are sealed by means of a sealing bar 9, so as to close the upper edges of internal sides 6 and 7 above
profiles 2, 3, and by means of sealing bar 9' withstriking member 10 the free profile is sealed to side 7. The envelopes of the present invention, with the above-described features, can be open for filling without any difficulty and therefore there is no risk to spoil the external surface of the envelopes, neither leakage of the product occurs. - Furthermore, once the sealing is broken, the envelope can be resealed by means of the pressure
plastic profiles - It is to be noticed that the male and female
pressure engaging members profile 3 is made integral with second inner side 7 only after filling of the envelope, with the above mentioned advantages. - It will be possible to make changes of practical-constructive type to the invention, without departing from the scope of the inventive idea as claimed below.
Claims (3)
- An envelope of plastic material (1) comprising two internal sides (6, 7) in the upper part of the envelope that are suited to be sealed by means of male and female pressure members (4, 5), characterized in that it comprises a profile (2) which is provided with said members and integral with a first inner side (6); and a free profile (3) which is provided with said members being engageable in the members of profile (2) and sealable to the second inner side (7) after filling of the envelope.
- The envelope according to claim 1, characterized in that the free profile (3) has the ends (3') fixed at the ends of profile (2) at the intersection points of the sides (6, 7).
- The envelope according to the previous claims, characterized in that the edges of the inner sides (6, 7) above the profiles (2, 3) are suited to be sealed each other by a sealing bar (9), and the side (7) too is suited to be sealed to the free profile (3) by means of a sealing bar (9') with a striking member (10).
